("Arq", the "Company," "we," "us", "our," or similar pronouns) is an environmental technology company principally engaged in the sale of consumable air, water, and soil treatment solutions including activated carbon ("AC") and chemical technologies. Our proprietary AC products enable customers to reduce air, water, and soil contaminants, including mercury, per - and polyfluoroalkyl substances ("PFAS") and other pollutants, to meet the challenges of existing and pending air quality and water regulations. We manufacture and sell AC and other chemicals used to capture and remove contaminants for the coal-fired power generation, industrial, municipal water and air, water and soil treatment and remediation markets (collectively, the advanced purification technologies or "APT" market). Our predecessor, ADA-ES, Inc. ("ADA"), a Colorado corporation, was incorporated in 1997. Pursuant to an Agreement and Plan of Merger, effective July 1, 2013, the Company (formerly known as Advanced Emissions Solutions, Inc. ("ADES")), a Delaware company incorporated in 2011, succeeded ADA as the publicly-held corporation and ADA became a wholly-owned subsidiary of the Company. In 2018, we acquired ADA Carbon Solutions, LLC ("Carbon Solutions") to enter into the broader AC market and to expand our product offerings in the mercury control industry and other applicable AC markets. In February 2023, we acquired 100% of the equity of the subsidiaries of Arq Limited (the "Arq Acquisition," and hereafter the Arq Limited subsidiaries referred to as "Legacy Arq") to secure access to a feedstock, a manufacturing facility and certain patented processes to manufacture new advanced granular activated carbon ("GAC") products for sale into markets to the APT and other markets. In February 2024, as part of a larger rebranding, the Company changed its name to Arq, Inc., and on February 1, 2024, our common stock commenced trading under the ticker symbol, "ARQ". This Annual Report on Form 10-K is referred to as the "Form 10-K" or the "Report." As used in this Report, the terms the "Company," "we," "us" and "our" means Arq, Inc. and its consolidated subsidiaries. Products and Markets AC is a specialized sorbent material that is used widely in a host of industrial and consumer applications to remove impurities, contaminants and pollutants from gas, water, soil and other product or waste streams. AC is produced by activating carbonaceous raw materials, including wood, coal, nut shells, resins and petroleum pitch. Properties such as surface area, pore volume, surface chemical functionalities and particle size and form can be specifically engineered to selectively target various contaminants to meet end-use application requirements. Our AC products are manufactured in several different forms that are important for the end-use application, including powdered activated carbon ("PAC"), granular activated carbon, and colloidal carbon product ("CCP"). Key markets for AC products include removal of pollutants from coal-fired electrical generation and other industrial processes, treatment of drinking and waste waters, industrial and renewable gas purification and odor removal, automotive gasoline emission control, soil and ground water remediation and food and beverage process and product purification. Demand for AC products has been, and is expected to continue to be driven by increasing environmental regulations pertaining to water, soil, and air quality, especially in the developed and more industrialized areas of the world, and general consumer attention towards environmental issues. Additionally, we believe enhanced environmental and health advisory issues will continue to drive demand for AC in rapidly developing countries. We pursue opportunities to expand and diversify our customer base into markets for our purification products including industrial applications, water treatment plants and other end markets. In addition, we see significant opportunities emerging in the soil, sediment and groundwater treatment markets. Increased attention has been drawn to the monitoring and treatment of heavy metals, organic and inorganic compounds in groundwater to improve overall ground and drinking water quality across North America. AC, in various forms, has and will continue to play a key role in these remediation efforts. Our current products (also referred to as "consumables") are used to purify contaminated liquid, soil, and gas streams from a variety of industrial sources including coal-fired power plants and wastewater treatment plants and other end markets. Most of the North American coal-fired power generators installed equipment to control air pollutants, such as mercury, prior to or since the implementation of the Mercury and Air Toxics Standards ("MATS"). However, many power generators need consumable products to complement the operation of installed equipment on a recurring basis to more effectively capture mercury and other contaminants. AC has been adopted as the most widely-used technology to capture mercury due to product efficiency and 1 -------------------------------------------------------------------------------- effectiveness, and currently accounts for the majority of the mercury control consumables in the North American market. We offer AC and other chemical products and work with customers as they develop and implement a compliance control strategy that utilizes the consumables solutions that fit with their unique operating and pollution control configuration. Coal-fired power plants continue to be a significant, though declining, source of electricity generation in the United States ("U.S."). Demand for our AC products related to coal-fired electricity generation is highly dependent on the availability and cost of alternative energy sources, such as natural gas, solar and wind energy. We continue to pursue markets for our purification products outside of coal-fired power generation, including industrial applications, (such as waste-to-energy and cement making), water treatment and other markets. For the purification of water, our AC products have been used in the treatment of drinking water, wastewater, contaminated soil and groundwater to adsorb compounds causing unpleasant taste and odor and other toxic contaminants. Both industrial and municipal wastewater treatment plants have deployed the use of our AC products in their treatment processes. Groundwater contamination has become a matter of increasing concern to federal and state governments as well as to the public, especially over recent years. The U.S. AC market may see significant growth from water purification markets, especially if future regulations are passed controlling certain chemicals in drinking water. At present, individual states are primarily responsible for the protection of groundwater and drinking water. The existing technologies for treatment of groundwater, including removal of the soil for external treatment or landfill, pumping the groundwater above surface for treatment and/or installing treatment trenches or barriers all utilize PAC and GAC products. An emerging technology generating increasing interest by site engineering firms and owners is injecting highly engineered ACs into the subsoil, also described as "in situ" treatment, to intercept the contamination plume or to treat the groundwater. In response to this market opportunity, in late 2021, we developed a new Colloidal Carbon Product ("CCP") platform, FluxSorb RC, which is currently in the initial stages of field testing at multiple contaminated soil and groundwater remediation treatment sites. Legacy Arq Products and Markets With the acquisition of Legacy Arq in February 2023, we now control bituminous coal waste reserves and own a manufacturing facility, both located in Corbin Kentucky (the "Corbin Facility"). Our facility will remediate these reserves, using a patented manufacturing process to convert bituminous coal waste into a purified, microfine carbon powder known as Arq powderTM ("Arq Powder") for high value applications, such as for a raw material to produce GAC products. We expect by the end of 2024 to begin using Arq Powder as a feedstock to produce high-quality GAC products for sale in the APT and other markets. We believe Arq Powder has additional potential for us to access new markets and applications. We expect to secure customer interest in Arq Powder as an additive into other markets, such as components for asphalt. These products utilizing Arq Powder are expected to have a lower carbon footprint compared to similar products utilizing conventional materials. These applications are currently in various stages of proof of concept testing or preliminary customer testing. Sales and Customers We sell consumables primarily though our internal sales group and are generally under contracts ranging from one to five years. We generally recognize revenue on an order-by-order basis. Revenue from our top three customers comprised approximately 37% of our consumables revenue for the year ended December 31, 2023, and the loss of any of these customers would have a material adverse effect on our operating results. Seasonality The timing of the sale of our consumable products is dependent upon several factors. Power generation is weather dependent, with electricity and steam production varying in response to heating and cooling demands. As a result, our revenue is generally higher in our first and third fiscal quarters during the warmer and colder months of the year. Abnormally high and low temperatures during the summer and winter months, respectively, may significantly increase coal consumption for electricity generation and cause increased impurities within various municipalities' water sources, and thus increase the demand for our products. Additionally, power generating units routinely schedule maintenance outages in the spring and/or fall depending on the operation of their boilers. During the period in which an outage may occur, which may range from one week to over a month, our product sales may decrease. Also, our revenue and sales volumes are highly dependent upon the level of coal consumption at coal-fired power plants, which in turn is significantly affected by the prices of competing power generation sources, such as natural gas and renewables. 2 -------------------------------------------------------------------------------- During periods of low natural gas prices, natural gas provides a competitive alternative to coal-fired power generation and therefore, coal consumption for power generation may be reduced, which in turn reduces the demand for our products. In contrast, during periods of higher prices for competing power generation sources, coal consumption generally increases and thus demand for our products also increases. In water purification, the sale of our products depends on demand from municipal water treatment facilities that use these products. Depending on weather conditions and other environmental factors, the summer months historically have the highest demand for our PAC products in water treatment. One of the major uses for PAC is for the treatment of taste and odor episodes caused by increased degradation of organic contaminants and natural materials in water that occurs during the summer months. Additionally, the rainy season generally results in more demand for PAC products to water municipalities due to rain run-offs and contaminant dilution. Competition Our primary competitors in the AC consumables industry include Cabot Norit Americas, Inc., which is owned by One Equity Partners, Calgon Carbon, which is owned by Kuraray Co., Ltd. and Donau Carbon Company. Sources and Availability of Raw Materials Currently, the principal raw material we use in the manufacturing of AC is lignite coal, which is readily available through our 100% ownership of a lignite coal mine (the "Five Forks Mine") located in Saline, Louisiana. All production from the Five Forks Mine is used in our manufacturing process. The Five Forks Mine is operated for us by a subsidiary of the North American Coal Company. We may also periodically purchase various ACs to supplement our inventory levels or to produce various products to serve certain AC markets. We purchase these various ACs through supply agreements or spot purchases with the producers. With the Arq Acquisition, in 2023, we secured a second feedstock, Arq Powder, which is made from bituminous coal waste, used in manufacturing of GAC products. Through internal testing, we have demonstrated that Arq Powder can be shaped and successfully activated using industrially available equipment and technology with our proprietary know-how. Arq Powder has unique properties, including low levels of impurities and small average particle size, which when used as a feedstock to produce certain carbon products may provide for advantages compared to lignite coal, other bituminous coals, or oil-based feedstocks in terms of cost and performance. In the U.S., the availability of feedstock for GAC manufacturing is limited, as it is either supplied by specialty mined coal or coconut husks, which need to be imported. Between the Corbin Facility and the Five Forks Mine, we will have a fully integrated supply chain in multiple feedstocks - bituminous coal fines (Corbin Facility) and lignite coal (Five Forks Mine) to produce both GAC and PAC products. We purchase various additives utilized in the production of AC. The manufacturing of AC is dependent upon these various additives, which are subject to price fluctuations and supply constraints. In addition, the number of suppliers who provide the necessary additives needed to manufacture our ACs is limited. We purchase these additives through supply agreements or spot purchases with the producers. Supply agreements with these producers are generally renewed on an annual basis. We also purchase additives that are included in certain chemical products for resale to our customers through contracts with suppliers. The manufacturing of these chemical products is dependent upon certain discrete additives, which are subject to price fluctuations and supply constraints. In addition, the number of suppliers who provide the necessary additives needed to manufacture our chemical products are limited. We purchase these chemical products through spot purchases with the producers. Due to the seasonality of our business, which is primarily driven by our high concentration of customers in the coal-fired plant market, our sales and inventory levels may vary throughout the year. We are able to supplement the available production at our Red River Plant by purchasing third party consumables to meet customer demand for our consumables. Facilities We own and operate a manufacturing plant (the "Red River Plant"), located in Coushatta, Louisiana. We also operate a production and distribution facility located on land we lease in Coushatta. In addition, we own and operate the Corbin Facility, where we process bituminous coal waste and apply patented technology to produce Arq Powder. In January 2024, the Company executed a contract with a third-party contractor for the construction of a GAC facility at the Red River Plant, (the "GAC Facility") and immediately commenced construction operations. The Company expects to complete commissioning activities at the GAC Facility by the end of 2024 and estimates that total construction costs including all equipment purchases will be in the range of $62 to $67 million. 3 -------------------------------------------------------------------------------- As of January 2024, major construction work at the Corbin Facility remains on track to be completed on time. We expect to commence commissioning activities during the first half of 2024 and estimate that total construction and commissioning costs at the Corbin Facility will be in the range of $10 to $15 million. In March 2023, we sold 100% of the membership interests in Marshall Mine, LLC, which owned a shuttered lignite mine located outside of Marshall, Texas to a third party. Research and Development Activities We conduct research and product development activities for further enhancement of our consumables. For the years ended December 31, 2023 and 2022, we incurred research and development costs of $3.3 million and $2.1 million, respectively. Legislation and Environmental Regulations Our products and services are used for the reduction of pollutants and other contaminants. Legislation and regulations limit the amount of pollutants and other contaminants permitted and may increase the need for our products. Below is a summary of the primary legislation and regulation that currently affects the market for our current products. Federal MATS Affecting Electric Utility Steam Generating Units The U.S. Environmental Protection Agency ("EPA") final "MATS Rule" went into effect in April 2012. The EPA structured the MATS Rule as a Maximum Achievable Control Technology-based ("MACT-based") hazardous pollutant regulation applicable to coal and oil-fired Electric Utility Steam Generating Units ("EGU"). EGUs generate electricity through steam turbines and have a capacity of 25 megawatts or greater and provide for, among other provisions, control of mercury, control of acid gases such as hydrochloric acid and other Hazardous Air Pollutants ("HAPs"). Approximately 1,260 units in the U.S. were coal-fired EGUs when the rule was enacted. According to our estimates, the MATS Rule sets a limit that we believe requires the capture of 80-90% plus of the mercury in the coal burned in electric power generation boilers as measured at the exhaust stack outlet for most plants. The MACT-based standards are also known as National Emission Standards for Hazardous Air Pollutants ("NESHAP"). Plants generally had four years to comply with the MATS Rule, and implementation of the MATS Rule is now largely completed. We estimate that 58% of the coal-fired units that were operating in December 2012 when the MATS Rule was finalized have been permanently shut down, leaving approximately 406 units in operation in the U.S. as of December 31, 2023. In May 2020, the EPA reconsidered and found that it was not "appropriate and necessary" to regulate HAPs emissions from coal- and oil-fired EGUs. However, the EPA expressly stated that the reconsideration neither removed coal- and oil-fired EGUs from the list of sources that must comply with the MATS rule, nor rescinded the MATS Rule, which has remained continuously in effect. On February 15, 2023, the EPA issued a final rule revoking the May 2020 reconsideration and affirming that it is "appropriate and necessary" to regulate HAP emissions from coal- and oil-fired EGUs. On April 3, 2023, the EPA issued a proposed update to MATS that, amongst other potential modifications, proposed a reduction to the mercury emission limits for lignite coal-fired EGUs. This proposal is currently pending. State Mercury and Air Toxics Regulations Affecting EGUs In addition, certain states have their own mercury rules that are similar to or more stringent than the MATS Rule. Coal-fired electricity generating units in the U.S. are subject to consent decrees that require the control of acid gases and particulate matter, in addition to mercury emissions. U.S. Federal Industrial Boiler MACT In January 2013, the EPA issued the final set of adjustments to the MACT-based air toxics standards for industrial boilers, including mercury, particulate matter and acid gas emission limits. Existing boilers typically had until January 31, 2017 to comply with the rule. The EPA published an amended final rule of the industrial boiler MACT ("IBMACT"), representing technical corrections and clarifications. On July 21, 2022, the EPA issued a further update of the IBMACT, which, among other things, updated emission limits to certain HAPs. The EPA estimated that approximately 600 coal-fired boilers will be affected by IBMACT, in industries such as pulp and paper. Our estimates, based on conversations with plant operators, suggest that most of the affected plants have either shut down or switched fuels to natural gas to comply with the regulation. 4 -------------------------------------------------------------------------------- Effluent Limitation Guidelines In 2015, the EPA set the first federal limits known as effluent limitation guidelines ("ELGs") on the levels of toxic metals in wastewater that can be discharged from power plants. The final rule requires, among other things, zero discharge for fly ash and bottom ash transport water and limits on mercury, arsenic, selenium, and nitrate from flue gas desulfurization ("FGD") wastewater. In September 2017, the EPA finalized a rule that delayed the original compliance deadlines for certain wastewater streams from November 2018 to November 2020, with the possibility that plants would not need to comply until December 2023 with state approval. In April 2019, the U.S. Court of Appeals for the Fifth Circuit struck down the EPA’s ELGs that apply to leachate wastewater and "legacy wastewater," and directed the EPA to revise the limits on the levels of toxic metals in those wastewater streams. In November 2019, the EPA proposed to revise the ELGs for bottom ash and FGD wastewater. The final rule, published in the Federal Register on October 13, 2020 and effective on December 14, 2020, does not directly regulate halogens. It does, however, propose to establish a voluntary incentives program for the removal of certain halides. In many (though not all) of the proposed treatment options that the EPA is considering, selenium in FGD wastewater would be regulated. Some halogens may impact the effectiveness of biological wastewater treatment systems that are often used for the removal of selenium. On August 3, 2021, the EPA initiated a supplemental rule-making initiative to strengthen certain discharge limits and stated its intention to issue a proposed rule for public comment in Fall of 2022, and issued a proposed rule on ELGs for the Steam Electric Power Generating Category on March 29, 2023. This proposed rule seeks to establish more stringent discharge standards for certain wastewater generated at coal fired power plants, and is currently under review by the EPA. Additional U.S. Legislation and Regulations In October 2021, the EPA released its PFAS Strategic Roadmap, laying out its approach to addressing PFAS and other pollutants. The PFAS Strategic Roadmap sets timelines by which the EPA plans to take certain actions through 2024, including establishing a national primary drinking water regulation for certain PFAS and taking Effluent Limitations Guidelines actions to regulate certain PFAS discharges from industrial categories. On March 14, 2023, the EPA proposed a National Primary Drinking Water Regulation ("NPDWR") for six specific PFAS substances. NPDWR seeks to establish legally enforceable maximum contaminant levels ("MCL") for the 6 PFAS substances, including a proposed MCL for Perfluorooctane Acid ("PFOA") and Perfluorooctane Sulfonate ("PFOS") of 4.0 parts per trillion. Under this proposed rule, drinking water utilities would have three years from the publication of a final rule to comply. The EPA has submitted its final rule with respect to the NPDWR for interagency review and should issue a final rule after this review is completed. International Regulations There are various international regulations related to mercury control. In Canada, the Canada-Wide Standard ("CWS") was initially implemented in 2010, with increasingly stringent limits through 2020 and varying mercury emissions caps for each province. China and Germany both have limits for mercury emissions that are less stringent than U.S. limits and are typically met using co-benefits from other installed air pollution control equipment designed to control other pollutants. In May 2017, the EU ratified the Minimata Convention on Mercury, triggering mercury control regulations with implementation starting in 2021. Specific emissions limits for dust, nitrogen oxides (NOx), sulfur dioxide (SO2), mercury and particulate matter (PM) are currently being developed, guided by the best available technologies reference ("BREF") document for limiting stack emissions and liquid effluents from industrial processes. The BREF conclusions for large coal-fired electricity generating units were adopted by the European Commission in July 2017. In October 2022, the European Commission proposed new directives for better and more cost-effective treatment of urban wastewater, which included amongst other things new standards on micropollutants and new monitoring requirements for microplastics. In January of 2024, there was a provisional agreement that revised the October 2022 proposed directives. If the revised directive is adopted by the European Parliament and the Council, it will become enforceable on European Union Member States. Based on the existing and potential regulations, we believe the international market for activated carbon products may expand in the coming years. 5 -------------------------------------------------------------------------------- Mining Environmental and Reclamation Matters Federal, state and local authorities regulate the U.S. coal mining industry with respect to matters such as employee health and safety and the environment, including the protection of air quality, water quality, wetlands, special status species of plants and animals, land uses, cultural and historic properties and other environmental resources identified during the permitting process. Reclamation is required during production and after mining has been completed. Materials used and generated by mining operations must also be managed according to applicable regulations and law. The Surface Mining Control and Reclamation Act of 1977 ("SMCRA"), establishes mining, environmental protection, reclamation and closure standards for all aspects of surface mining. Mining operators must obtain SMCRA permits and permit renewals from the Office of Surface Mining (the "OSM") or from the applicable state agency if the state agency has obtained regulatory primacy. A state agency may achieve primacy if the state regulatory agency develops a mining regulatory program that is no less stringent than the federal mining regulatory program under SMCRA. The Five Forks Mine operates in Louisiana, which has achieved primacy and issues permits in lieu of the OSM. Mine operators are often required by federal and/or state laws, including SMCRA, to assure, usually through the use of surety bonds, payment of certain long­term obligations including mine closure or reclamation costs, federal and state workers’ compensation costs, coal leases and other miscellaneous obligations. Although surety bonds are usually non-cancelable during their term, many of these bonds are renewable on an annual basis and collateral requirements may change. As of December 31, 2023, we posted a surety bonds of approximately $7.5 million and $3.0 million for reclamation of the Five Forks Mine and the Corbin Facility, respectively. Intellectual Property As of December 31, 2023, we held 83 U.S. patents and 8 international patents that were issued or allowed, 13 additional U.S. provisional patents or applications that were pending, and 2 international patent applications that were either pending or filed relating to different aspects of our technology. During the year ended December 31, 2023, we were granted 3 new patents, and obtained an additional 87 patents and patent applications through the Arq Acquisition. Within the Legacy Arq patent portfolio, there are 7 granted U.S. patents, 10 pending U.S. applications, 19 granted international patents, and 51 pending international patent applications. Our existing patents generally have terms of 20 years from the effective date of filing, with our next patents expiring in 2024. During the year ended December 31, 2023, 7 U.S. and 6 international patents and applications from our patent portfolio were abandoned, as we determined that they no longer represent future markets or economic opportunities for us. Further, 22 international patents and applications from the Legacy Arq patent portfolio were abandoned in jurisdictions that were determined to no longer represent future markets or economic opportunities for us. As of December 31, 2023, we owned over 50 trademark registrations and applications globally. During the year ended December 31, 2023, we obtained an additional 33 trademarks from the Arq Acquisition. Safety, Health and Environment Our operations are subject to numerous federal, state, and local laws, regulations, rules and ordinances relating to safety, health, and environmental matters ("SH&E Regulations"). These SH&E Regulations include requirements to maintain and comply with various environmental permits related to the operation of many of our facilities, including mine health and safety laws required for continued operation of the Five Forks Mine. Employees As of December 31, 2023, we employed 173 personnel, of which 171 were employed full-time. Arq Acquisition On February 1, 2023 (the "Acquisition Date"), we entered into a Securities Purchase Agreement (the "Purchase Agreement") with Arq Limited ("Arq Ltd."), a company incorporated under the laws of Jersey, pursuant to which we acquired all of the direct and indirect equity interests of Arq Ltd.'s subsidiaries (the "Arq Acquisition," and hereafter referred to as "Legacy Arq") in exchange for consideration (the "Purchase Consideration") totaling $31.2 million and consisting of (i) 3,814,864 shares of the Company's common stock, par value $0.001 per share (the "Common Stock"), valued at $12.4 million and (ii) 5,294,462 shares of the Company's Series A Convertible Preferred Stock, par value $0.001 per share (the "Series A Preferred Stock"), valued at 6 -------------------------------------------------------------------------------- $18.8 million. On June 13, 2023, our stockholders approved the conversion of all of the outstanding shares of the Series A Preferred Stock and the corresponding issuance of 5,362,926 shares of Common Stock. On February 1, 2023, and pursuant to the Arq Acquisition, we entered into subscription agreements with certain persons (the "Subscribers"), which included existing shareholders of Arq Ltd., three of which were appointed to our board of directors, pursuant to which the Subscribers subscribed for and purchased 3,842,315 shares of Common Stock for an aggregate purchase price of approximately $15.4 million and at a price per share of $4.00 (the "PIPE Investment"). The securities issued to the Subscribers under the Subscription Agreements were issued pursuant to an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"), Rule 506 of Regulation D, which is promulgated thereunder, and Regulations S of the Securities Act. The Company and its affiliates relied on this exemption from registration based in part on representations made by each of the Subscribers under the Subscription Agreements. Pursuant to the terms of the Purchase Agreement, we entered into a Registration Rights Agreement (the "Registration Rights Agreement") with Arq Ltd. and the Subscribers to the Subscription Agreements described above. On January 25, 2024, we filed a registration statement on Form S-3/A with the Securities and Exchange Commission ("SEC") to register all shares of Common Stock issued in the Purchase Agreement, all shares of Common Stock issued in the PIPE Investments, and all shares of Common Stock issued from the conversion of all shares of the Series A Preferred Stock subject to the Registration Rights Agreement and 325,457 underlying shares of Common Stock issuable upon the exercise of the Warrant (as defined below) issued as consideration in the CFG Loan (as defined below). The registration was declared effective by the SEC on January 31, 2024. Loan Agreement On February 1, 2023, and pursuant to the Arq Acquisition, we, as borrower, certain of subsidiaries, as guarantors, and CF Global Credit, as administrative agent and lender, entered into a $10.0 million term loan (the "CFG Loan") upon execution of a Term Loan and Security Agreement (the "Loan Agreement"). The CFG Loan has a term of 48 months and bears interest at a rate equal to either (a) Adjusted Term SOFR (subject to a 1.00% floor and a 2.00% cap) plus a margin of 9.00% paid in cash and 5.00% paid in kind or (b) Base Rate plus a margin of 8.00% paid in cash and 5.00% paid in kind, which interest on the CFG Loan in each case shall be payable (or capitalized, in the case of in kind interest) quarterly in arrears. In addition, in connection with the Loan Agreement and as consideration for the CFG Loan, we issued to CF Global a warrant (the "Warrant") to purchase 325,457 shares of Common Stock. The Warrant has an exercise price of $0.01 per share, subject to adjustment as set forth in the Warrant, is exercisable immediately, contains a cashless exercise provision and expires on February 1, 2030.

You are cautioned not to place undue reliance on the forward-looking statements made in this Report and to consult filings we have made and will make with the SEC for additional discussion concerning risks and uncertainties that may apply to our business and the ownership of our securities. The forward-looking statements contained in this Report are presented as of the date hereof, and we disclaim any duty to update such statements unless required by law to do so. 9 -------------------------------------------------------------------------------- Item 1A. Risk Factors The following risks relate to us as of the date this Report is filed with the SEC. This list of risks is not intended to be exhaustive, but reflects what we believe are the material risks inherent in our business and the ownership of our securities as of the specified dates. A statement to the effect that the occurrence of a specified event may have a negative impact on our business, results of operations, profitability, financial condition, or the like, is intended to reflect the fact that such an event, if it occurs, would be likely to have a negative impact on your investment in Arq, but should not imply the likelihood of the occurrence of such specified event. The order in which the following risk factors are presented is not intended as an indication of the relative seriousness of any given risk. Risks Related to Our Business We may be unable to meet our projected construction timelines, costs and production ramp up for our capital upgrades at our Red River Plant, or we may experience difficulties in generating and maintaining demand for products manufactured there. Our ability to increase production of GAC on a sustained basis is dependent on the construction and ramp of upgrades at our Red River Plant. The construction of and commencement and ramp of production at this facility are subject to a number of uncertainties inherent in all new manufacturing operations. These include ongoing liquidity requirements for funding the expansion of the facility, ongoing compliance with regulatory requirements, procurement and maintenance of construction materials and services, environmental and operational licenses and approvals for additional expansion, supply chain constraints, hiring, training and retention of qualified employees and the pace of bringing production equipment and processes online with the capability to manufacture high-quality GAC products at scale. If we experience any issues or delays in meeting our projected timelines, costs, or production capacity for the upgrades at the Red River Plant, or generating and maintaining demand for the products we manufacture there, our business, prospects, operating results and financial condition may be harmed. The Company anticipates financing the timely completion of the upgrades to our Red River Plant funded with cash on hand, cash generation, ongoing cost reduction initiatives, potential customer prepayments for GAC contracts, and a planned refinancing and potential expansion of our term loan. If we are not able to secure additional financing, the project timeline for our Red River Plant expansion may be delayed beyond the end of 2024. Our future financial results will suffer if we do not effectively manage our expanded operations following the Arq Acquisition. Following the Arq Acquisition, the size of our business has increased. Our future results depend, in part, upon our ability to manage this expanded business, which poses substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. There can be no assurance that we will be successful or that we will realize the expected operating efficiencies, cost savings, revenue enhancements and other benefits currently anticipated from the Arq Acquisition. Manufacturing Legacy Arq's products and GAC products requires significant capital. Legacy Arq was a development stage entity that to date has not generated any revenue. Legacy Arq has historically had operating losses and required multiple financing rounds to fund its business plan. We are currently spending significant capital to execute our business plan to manufacture Legacy Arq’s products as a feedstock for GAC products. A significant funding source is our cash on hand. We are targeting the end of 2024 for our first commercial production of Legacy Arq products and the end of 2024 for our first commercial production of GAC products. To meet these production timing goals, we will need to raise additional capital in 2024. We may not be successful in obtaining the required financing or, if financing is available to us, such financing may not be on terms that are favorable to us. The failure to obtain financing in 2024 in order to enable the Company to produce Legacy Arq products and GAC products by the end of 2024 could result in a delay in executing our business plan. The Arq Acquisition is requiring significant technological changes in manufacturing that may adversely affect the market acceptance of Legacy Arq’s products. We will be producing new products that we have not yet sold commercially. As such, production to date has not been at full throughput. Legacy Arq’s manufacturing technology has been extensively tested at scale, but continuous operations represent risks including an inability to achieve the scale-up efficiencies that have been assumed in our business plan. In turn, this could 10 -------------------------------------------------------------------------------- impact throughput in the Corbin Facility, which could lead to lower production and higher operating costs. There is also risk of delays that are product-specific. For example, we may not receive adequate customer acceptance or achieve acceptable performance given the specification differentiation between some of Legacy Arq’s products and the industry’s existing conventional products. These risks could have a material adverse effect on our business, operating results and financial condition. There could be no future demand for Legacy Arq’s products. Our initial use for Arq Powder is as a feedstock for AC, and although we believe current conditions are favorable as a result of excess demand versus supply, there can be no guarantee that this will continue. Drivers of demand include factors beyond our control such as population growth and GDP growth, amongst others. Any major global downturn could also materially negatively impact this demand. New AC supply is driven by new manufacturing sites being built, and we have little visibility on what additional manufacturing capacity other manufacturers may add in the future. Our business plan and commercial success also assumes selling Arq Powder into new markets, including as an additive into the carbon black and asphalt markets. Although testing data and feedback from potential customers have been positive to date, there can be no assurance that these products will be commercially viable. As we attempt to develop and grow Arq Powder utilization worldwide, our success will depend on our ability to correctly forecast demand in these new markets. There is no assurance that we will be able to increase our business to meet targets globally, or that projections on which such targets are based will prove accurate, or that the pace of growth or coverage will meet customer expectations. Disruptions at any of our facilities could negatively impact our ability to meet customer supply requirements due to damage to or insufficient production capacity of the Red River Plant and may have a material adverse effect on our business, results of operations and financial condition. We own and operate the Red River Plant, which is our sole manufacturing plant for producing and selling AC products to our customers, and are completing construction and commissioning activities on the Corbin Facility. Our current and future ability to meet customer expectations, manage inventory, complete sales and achieve our objectives for operating efficiencies depends on the full-time operation of the Red River Plant, and the execution of our business plan depends on the completion of the Corbin Facility and the GAC expansion at the Red River Plant. We cannot replicate our manufacturing methods at another plant due to the limited availability of similar manufacturing plants, the additional costs incurred in supplying raw materials such as lignite to another plant, and the risk of revealing our confidential and proprietary technologies and manufacturing processes. If we experience a disruption at these facilities, due to natural disasters, extreme weather, other unanticipated problems such as labor difficulties, pandemics (including the COVID-19 pandemic), equipment failure, cyberattacks or other cybersecurity incidents, capacity expansion difficulties or unscheduled maintenance, we would suffer a loss of inventory to supply customers, likely incur additional costs to deliver products to our customers, and disrupt the ordinary course of our business. In addition, if contractual demand exceeds manufacturing capacity, we would jeopardize our ability to fulfill obligations under our contracts, which could, in turn, result in reduced sales, profitability, contract penalties or terminations and damage to our customer relationships and could have a material adverse effect on our business. While we have insured our facilities against damage or destruction as well as for losses from business interruptions, there can be no assurance that any insurance coverage will be sufficient to cover any such losses. Further, a prolonged disruption in our operations at the Red River Plant due to downtime or having to meet customer requirements that exceed our maximum manufacturing capacity would require us to seek alternative customer supply arrangements, which may not be on attractive terms to us or could lead to delays in distribution of products to our customers, either of which could have a material adverse effect on our business, results of operations and financial condition. There can be no assurance that the Arq Acquisition will result in additional value for our stockholders. There can be no assurance that the Arq Acquisition will provide greater value to our stockholders than that reflected in the current price of our common stock. As a result of the Arq Acquisition, perceived uncertainties related to our future may result in the loss of potential business opportunities and volatility in the market price of our common stock, which may make it more difficult for us to attract and retain qualified personnel and business partners. 11 -------------------------------------------------------------------------------- In connection with the Arq Acquisition, we may be required to take write-downs or write-offs, restructuring and impairment or other charges that could negatively affect our business, assets, liabilities, prospects, outlook, financial condition and results of operations. Although we conducted extensive due diligence in connection with the Arq Acquisition, unexpected risks may arise and previously known risks may materialize in a manner not consistent with our preliminary risk analysis. Further, as a result of the Arq Acquisition, we may be required to take write-offs or write-downs, restructuring and impairment or other charges that could negatively affect our business, assets, liabilities, prospects, outlook, financial condition and results of operations. The failure to successfully integrate the Legacy Arq businesses in the expected timeframe could adversely affect our future business and financial performance. The combination of two independent companies is a complex, costly and time-consuming process. As a result, we have devoted significant management attention and resources to integrate Legacy Arq's business practices and operations. We may not be successful in integrating the operations of Legacy Arq or otherwise realizing the anticipated benefits of the Arq Acquisition. In addition, the integration of Legacy Arq may result in material unanticipated problems, expenses, liabilities, competitive responses, loss of customer relationships and diversion of management’s attention, and may cause our stock price to decline. The difficulties of combining the operations of the two companies include, among others: •managing a larger company; •coordinating geographically separate organizations; •the potential diversion of management’s focus and resources from other strategic opportunities and from operational matters; •performance shortfalls at one or both of the companies as a result of the diversion of management’s attention caused by completing the Arq Acquisition and integrating the combined companies’ operations; •aligning and executing a new business strategy; •retaining existing customers and attracting new customers; •maintaining employee morale and retaining key management and other employees; •the disruption of, or the loss of momentum in, each company’s ongoing business or inconsistencies in standards, controls, systems, procedures and policies; •integrating two unique business cultures, which may prove to be incompatible; •the possibility of faulty assumptions underlying expectations regarding the integration process; •consolidating corporate and administrative infrastructures and eliminating duplicative operations; •coordinating sales, distribution and marketing efforts; •maintaining research and development technology momentum and leading customer technical collaboration progress; •significant changes to current market conditions that may adversely affect the business plan; •integrating IT, communications and other systems; •changes in applicable laws and regulations; •managing tax costs or inefficiencies associated with integrating Legacy Arq's operations; •unforeseen expenses or delays associated with the Arq Acquisition; and •taking actions that may be required in connection with obtaining regulatory approvals. Many of these factors are outside of our control and any one of them could result in increased costs, decreased revenue and diversion of management’s time and energy, which could materially impact our business, financial condition and results of operations. In addition, even if the operations of Legacy Arq are integrated successfully, we may not realize the full benefits from the Arq Acquisition, including the synergies, cost savings or growth opportunities that we expect. These benefits may not be achieved within the anticipated timeframe, or at all. 12 -------------------------------------------------------------------------------- Specifically, the realization of the full benefits from the Arq Acquisition is dependent on our ability to construct expansions to existing facilities and to integrate Arq Powder on the projected timeline and within the projected budget. If these anticipated capital expenditures are delayed, whether as a result of unanticipated challenges in permitting, construction or economic conditions, the cost of such activities may increase and the timing of projected revenue may be impacted. Further, the costs of such construction activities may significantly exceed the budgeted costs. The costs of construction or other anticipated capital expenditures are subject to the effects of the current inflationary environment and we may not be able to successfully offset the effects of inflation. The synergies attributable to the Arq Acquisition may vary from expectations. We may fail to realize the anticipated benefits and synergies expected from the Arq Acquisition. Our success will depend, in significant part, on our ability to successfully integrate the Legacy Arq business and realize the anticipated strategic benefits and synergies. We believe that the combination of the two businesses will allow us to enter into more diversified, higher margin markets with our products. However, achieving these goals requires, among other things, realization of the targeted cost synergies expected from the Arq Acquisition. These anticipated benefits and actual operating, technological, strategic and revenue opportunities may not be realized fully or at all, or may take longer to realize than expected. If we are not able to achieve these objectives and realize the anticipated benefits and synergies expected from the Arq Acquisition within the anticipated timeframe or at all, our business, financial condition and operating results may be adversely impacted. Strategic relationships upon which we rely on are subject to change, which may diminish our ability to conduct our operations. Our ability to successfully produce Legacy Arq’s products and expand their utilization as intended depends on developing and maintaining close working relationships with industry participants. In addition, the dynamics of maintaining these relationships with strategic partners may require us to incur expenses or undertake activities we would not otherwise be inclined to do. If these strategic relationships are not established or maintained, our business prospects may be limited, which could negatively impact our business and results of operations. If we fail to develop or maintain an effective system of internal controls as we integrate Legacy Arq’s business operations and processes with ours, we may not be able to accurately report our financial results or prevent fraud. As a result, stockholders could lose confidence in our financial reporting, which would harm our business and the trading price of our common stock. Effective internal controls are necessary for us to provide reliable financial reports, prevent fraud and operate successfully as a public company. If we cannot provide reliable financial reports or prevent fraud, our reputation and operating results would be harmed. We cannot be certain that our efforts to develop and maintain an effective system of internal controls will be successful, will be able to maintain adequate controls over our financial processes and reporting in the future, or will be able to comply with our obligations under Section 404 of the Sarbanes-Oxley Act of 2002. Any failure to develop or maintain effective internal controls, or difficulties encountered in implementing or improving internal controls, could harm our operating results or cause us to fail to meet our reporting obligations. Ineffective internal controls could additionally lead to increased costs to remediate any failures and could cause investors to lose confidence in our reported financial information, which would likely have a negative effect on the trading price of our common stock. The financial effects of Tinuum Group providing indemnification under performance guarantees of its RC facilities are largely unknown and could adversely affect our financial condition. Tinuum Group, LCC ("Tinuum Group"), of which we hold a 42.5% ownership interest, indemnifies certain utilities and lessees of RC facilities for particular risks associated with the operations and tax treatment of those facilities. We have provided limited, joint and several guarantees of Tinuum Group’s obligations under those leases. To date, we have not been required to make any payments under such guarantees and are not aware of any actual or threatened requests or claims for payment under such guarantees. Nevertheless, if any such obligations are triggered in the future, any substantial payments made under such guarantees could have a material adverse effect on our financial condition, results of operations and cash flows. A pandemic, epidemic or outbreak of an infectious disease such as COVID-19 may materially adversely affect our business. The global or national outbreak of an infectious disease, such as COVID-19, may cause disruptions to our business and operational plans, which may include (i) shortages of employees, (ii) inefficiencies, delays and additional costs in our manufacturing, sales and customer service efforts, (iii) recommendations of, or restrictions imposed by, government and health authorities, including quarantines, to address an infectious disease, such as the COVID-19 pandemic, and (iv) restrictions that 13 -------------------------------------------------------------------------------- we impose, including facility shutdowns, to ensure the safety of employees and others. The COVID-19 pandemic has had, and continues to have, a significant impact around the world, prompting governments and businesses to take unprecedented measures in response. While it is not possible to predict their extent or duration, these disruptions may have a material adverse effect on our business, financial condition and results of operations. Demand for our products and services depends significantly on environmental laws and regulations related to emissions. Uncertainty as to the future of such laws and regulations, changes to such laws and regulations or granting of extensions of compliance deadlines has had, and will likely continue to have, a material effect on our business. A significant market driver for our existing products and services and those planned in the future are existing and expected environmental laws and regulations, particularly those addressing the reduction of mercury and other emissions from coal-fired electricity generating units and proposed regulation of PFAS and other pollutants. If such laws and regulations are delayed, or are not enacted or are repealed or amended to be less strict, or include prolonged phase-in periods, or are not enforced, our business would be adversely affected by declining demand for such products and services. For example: 1.The implementation of environmental regulations regarding certain pollution control and permitting requirements has been delayed from time to time due to various lawsuits. The uncertainty created by litigation and reconsideration of rule-making by the EPA has negatively impacted our business, results of operations and financial condition and will likely continue to do so. 2.To the extent federal, state and local legislation mandating that electric power generating companies serving a state or region purchase a minimum amount of power from renewable energy sources such as wind, hydroelectric, solar and geothermal, and such amount lessens demand for electricity from coal-fired plants, the demand for our products and services would likely decrease. Federal, state and international laws or regulations addressing emissions from coal-fired electricity generating units, climate change or other actions to limit emissions, including public opposition to new coal-fired electricity generating units, has caused and could continue to cause electricity generators to transition from coal to other fuel and power sources, such as natural gas, nuclear, wind, hydroelectric and solar. The potential financial impact on us of future laws or regulations or public pressure will depend upon the degree to which electricity generators diminish their reliance on coal as a fuel source. That, in turn, will depend on a number of factors, including the specific requirements imposed by any such laws or regulations, the periods over which those laws or regulations are or will be phased in, the amount of public opposition and the state and cost of commercial development of related technologies and processes. In addition, public utility commissions may not allow utilities to charge consumers for, and pass on the cost of, emissions control technologies without federal or state mandates. Our development operations at the Corbin Facility are subject to environmental permitting and regulations that can make operations expensive, or prohibit them altogether. We use coal waste as a feedstock to produce Arq Powder, and the majority of coal waste sites targeted by us for development contain potential environmental liabilities. Therefore, we may be subject to potential risks and liabilities associated with pollution of the environment and the disposal of waste products that could occur as a result of these development and production activities. Further, we cannot reasonably predict the impact that any such future laws or regulations or public opposition may have on our results of operations, financial condition or cash flows. With the Arq Acquisition, we are subject to additional significant governmental regulations, which may negatively impact our operations and costs of conducting business. The Corbin Facility's operations are governed by extensive laws and regulations, including: •laws and regulations related to exports, taxes and fees; •labor standards and regulations related to the MSHA; and •environmental standards and regulations related to waste disposal, toxic substances, land use and environmental protection, including environmental protection regulations related to water and air. Existing and possible future laws, regulations and permits governing operations and activities of energy waste companies, or more stringent implementation, could have a material adverse impact on our business and cause increases in capital expenditures or require abandonment or delays in our products. Any future regulations regarding CO2 emissions of coal reclamation and product manufacturing could also impact our future business. 14 -------------------------------------------------------------------------------- Action by the EPA related to Mercury and Air Toxics Standards ("MATS") that decreases demand for our mercury removal products could have a material adverse effect on our business. Our operating performance is largely dependent upon demand for mercury removal-related product, which is largely affected by the amount of coal-based power generation used in the U.S. and the continued regulation of utilities under MATS. In May 2020, the EPA reconsidered and withdrew its 2016 "supplemental finding" associated with the cost benefit analysis of the MATS Rule. In this action, the EPA found that it was not "appropriate and necessary" to regulate Hazardous Air Pollutants ("HAP") emissions from coal- and oil-fired Electric Utility Steam Generating Units ("EGUs"). However, the EPA expressly stated that the reconsideration neither removed coal- and oil-fired EGUs from the list of sources that must comply with the MATS rule, nor rescinded the MATS Rule, which has remained continuously in effect. On February 9, 2022, the EPA published a new proposed rule revoking the May 2020 withdrawal of the 2016 supplemental finding and affirming that it is "appropriate and necessary" to regulate HAP emissions from coal- and oil-fired EGUs. On February 15, 2023, the EPA issued a final rule revoking the May 2020 reconsideration and affirming that it is "appropriate and necessary" to regulate HAP emissions from coal- and oil-fired EGUs. On April 3, 2023, the EPA issued a proposed update to MATS that amongst other potential modifications, proposed a reduction to the mercury emission limits for lignite coal-fired EGUs. Any final action taken by the EPA related to MATS that decreases demand for our products for mercury removal will have a negative effect on our financial results. The timing and content of the proposed updates to the rule are unknown. The failure of tariffs placed on U.S. imports of Chinese AC to adequately address the impact of low-priced imports from China could have a material adverse effect on the competitiveness and financial performance of our business. Our business faces competition in the U.S. from low-priced imports of AC products. If the volumes of these low-priced imports increase, especially if they are sold at less than fair value, our sales of competing products could decline, which could have an adverse effect our earnings. In addition, sales of these low-priced imports may negatively impact our pricing. To limit these activities, regulators in the U.S. have enacted an anti-dumping duty order on steam AC products from China. In November 2023, the order was extended for an additional five years. The amount of anti-dumping duties collected on imports of steam AC from China is reviewed annually by the U.S. Department of Commerce. To the extent the anti-dumping margins do not adequately address the degree to which imports are unfairly traded, the anti-dumping order may be less effective in reducing the volume of these low-priced AC imports in the U.S., which could negatively affect demand and/or pricing for our products. The market for consumables and other products that provide pollutant reduction is highly competitive, and some of our competitors are significantly larger and more established than we are, which could adversely impede our growth opportunities and financial results. We operate in a highly competitive marketplace. Our ability to compete successfully depends in part upon our ability to maintain a production cost advantage, competitive technological capabilities and to continue to identify, develop and commercialize new and innovative products for existing and future customers. We may face increased competition from existing or newly developed products offered by industry competitors or other companies whose products offer a similar functionality as our products and could be substituted for our products, which may negatively affect demand for our products. In addition, market competition could negatively impact our ability to maintain or raise prices or maintain or grow our market position. Additionally, our competitors are significantly larger and/or more established companies in the market for consumables and other products that provide mercury emissions reduction, water treatment and air purification. Reduction of coal consumption by North American electricity power generators could result in less demand for our products and services. If utilities significantly reduce the number of coal-fired electricity generating units or the amount of coal burned without a corresponding increase in the services required at the remaining units, this could reduce our revenue and materially and adversely affect our business, financial condition and results of operations. The amount of coal consumed for North American electricity power generation is affected by, among other things, (1) the location, availability, quality and price of alternative energy sources for power generation, such as natural gas, fuel oil, nuclear, hydroelectric, wind, biomass and solar power; and (2) technological developments, including those related to competing alternative energy sources. Natural gas-fueled generation and renewable energy generation have displaced and may continue to displace coal-fueled generation, particularly from older, less efficient coal-powered generators. We expect that a significant amount of the new power generation necessary to meet increasing demand for electricity generation will be fueled by these sources. The price of natural gas has remained relatively competitive for power generation and the use of natural gas is perceived as having a lower environmental impact than burning coal. Natural gas-fired plants are cheaper to construct, and permits to construct these plants 15 -------------------------------------------------------------------------------- are easier to obtain, and ongoing costs of natural gas-fired plants associated with meeting environmental compliance are lower. Possible advances in technologies and incentives, such as tax credits that enhance the economics of renewable energy sources, could make those sources more competitive than coal. Any reduction in the amount of coal consumed by domestic electricity power generators, whether as a result of new power plants utilizing alternative energy sources or as a result of technological advances, could reduce the demand for our current products and services, thereby reducing our revenue and materially and adversely affecting our business and results of operations. Additionally, long-term changes in environmental regulation that threaten or preclude the use of coal or other fossil fuels as a primary fuel source for electricity production may result in the reduction or closure of a significant number of coal-fired electric generating units, and may adversely affect our business, financial condition and results of operations. The loss of, or significant reduction in, revenue from our largest customers could adversely affect our business, financial condition or results of operations. For 2023, we derived approximately 48% of our total consumable revenue from our five largest customers. Our top three customers accounted for approximately 37% of our total consumable revenue for 2023. If any of our five largest customers were to significantly reduce the quantities of consumables they purchase from us, it may adversely affect our business, financial condition and results of operations. Uncertain geopolitical conditions could adversely affect our business. Uncertain geopolitical conditions, including the conflicts in the Middle East, the invasion of Ukraine, sanctions against Russia and other potential impacts on the world economy and currencies may cause disruptions in our business. These include logistics delays or shortages in producing and shipping certain of our raw materials, increases in energy prices that could increase costs of certain of our raw materials, increases in transportation costs from overall higher gasoline prices and cyber-attacks targeted at U.S. power infrastructure that could impact demand for our products. Disruptions of supply chains may affect volatility in price and availability of raw materials. The continuation of geopolitical conflicts in 2023 has continued to disrupt supply chains, resulting in cost increases for commodities, goods and services in many parts of the world. Disruptions of supply chains and higher costs may continue into 2024 and beyond. The economic effects from these events over longer terms could negatively impact our business and results of operations. The manufacturing and processing of our consumable products requires significant amounts of raw materials. The price and availability of those raw materials can be impacted by factors beyond our control. Our consumable products, exclusive of lignite coal, use a variety of additives. Significant movements or volatility in the costs of additives could have an adverse effect on our working capital or results of operations. Additionally, we purchase certain raw materials from selected key suppliers. While we have inventory of such raw materials, if any of these suppliers are unable to meet their obligations with us on a timely basis or at an acceptable price, we may be forced to incur higher costs to obtain the necessary raw materials or be unable to obtain the materials. We may attempt to offset the increase in raw material costs or challenges in the supply of raw materials with price increases allowed in our contractual relationships, or through cost reduction efforts. If we are unable to fully offset the increased cost of raw materials through price increases, it could significantly impact our business, financial condition and results of operations. We may experience a shortage of reliable and adequate transport capacity and any material increase in transportation costs could have a material adverse effect on our results of operations. We currently plan to transport our Arq Powder based filter cake produced at the Corbin Facility ("Wet Cake") to the Red River Plant by rail and truck. We may experience roadway or railway transportation disruptions that could have a material adverse effect on our operations or financial condition. There can be no assurance that we will be able to secure sufficient truck or railway transport capacity to transport raw materials from the Corbin Facility to the Red River Plant. Further, in the event of railway transport shortages, there can be no assurance that road transportation will be able to satisfy the shortfall. Potential transportation classifications of raw materials may require permitting, and special care and handling to transport such materials. In addition, any material increase in transportation costs could have a negative effect on the competitiveness of our future products, which may in turn have a material adverse effect on our business and results of operations. 16 -------------------------------------------------------------------------------- We face operational risks inherent in mining operations, and our mining operations have the potential to cause safety issues, including those that could result in significant personal injury. We own the Five Forks Mine, a lignite coal mine located in Louisiana, which is operated for us by a third party. Mining operations by their nature involve a high level of uncertainty and are often affected by risks and hazards outside of our control. At the Five Forks Mine, the risks are primarily operational risks associated with the maintenance and operation of the heavy equipment required to dig and haul the lignite and risks relating to producing lower than expected lignite quality or recovery rates. Additionally, the cost of inputs in our mining operation, most notably fuel cost, can create operational risks. The failure to adequately manage these risks could result in significant personal injury, loss of life, damage to mineral properties, production facilities or mining equipment, damage to the environment, delays in or reduced production and potential legal liabilities. Our operations and products are subject to extensive safety, health and environmental requirements that could increase our costs and/or impair our ability to manufacture and sell certain products. Our ongoing operations are subject to extensive federal, state and local laws, regulations, rules and ordinances relating to safety, health and environmental matters, many of which provide for substantial monetary fines and potential criminal sanctions for violations. These include requirements to obtain and comply with various environmental-related permits for constructing any new facilities (or modifications to existing facilities) and operating all of our existing facilities. Costs of complying with regulations could increase, as concerns related to greenhouse gases and climate change continue to emerge. The enactment of new environmental laws and regulations and/or the more aggressive interpretation of existing requirements could require us to incur significant costs for compliance or capital improvements or limit our current or planned operations, any of which could have a material adverse effect on our earnings or cash flow. We may attempt to offset the effects of these compliance costs through price increases, productivity improvements and cost reduction efforts. Our success in offsetting any such increased regulatory costs is largely influenced by competitive and economic conditions and could vary significantly depending on the market segment served. Such increases may not be accepted by our customers, may not be sufficient to compensate for increased regulatory costs or may decrease demand for our products and our volume of sales. We may not be successful in achieving our growth expectations related to new products in our existing or new markets. Our ability to bring new products to the market will depend on various factors, including, but not limited to, solving potential technical or manufacturing difficulties, competition and market acceptance, which may hinder the timeliness and cost to bring such products to production. Further, there can be no assurance that costs incurred to develop new products will result in an increase in revenue. These factors or delays could affect our future operating results. Natural disasters or extreme weather could affect our operations and financial results. We operate facilities, including the Red River Plant, Five Forks Mine and the Corbin Facility, that are exposed to natural hazards, such as floods, windstorms and hurricanes. Extreme weather events present physical risks that may become more frequent as a result of factors related to climate change. Such events could disrupt our supply of raw materials or otherwise affect production, transportation and delivery of our products or affect demand for our products. In addition, extreme and unusually cold or hot temperatures throughout the U.S. could result in abnormally high loads on geographic electrical grids that could result in the failure of coal-fired power plants to produce electricity. If these plants were off-line for a significant period of time, the demand for our products could be less, which would impact our operations and financial results. Conversely, abnormally high loads on geographic electrical grids, resulting in increased demand of coal-fired power plants to produce electricity, could impact our ability to meet customer contracts and demands. Failure to effectively monitor and respond to environmental, social or governance (“ESG”) matters, including our ability to set and meet reasonable goals related to climate change and sustainability efforts, may negatively affect our business and operations. Regulatory developments and stakeholder expectations relating to ESG matters are rapidly changing. Concern over climate change has increased focus on the sustainability of practices and products in the markets we serve, and changes to laws and regulations regarding climate change mitigation may result in increased costs and disruption to operations. Moreover, the standards by which ESG matters are measured are developing and evolving, and certain areas are subject to assumptions that could change over time. If we are unable to recognize and respond to such developments, or if our existing practices and procedures are not adequate to meet new regulatory requirements, we may miss corporate opportunities, become subject to regulatory scrutiny or third-party claims, or incur costs to revise operations to meet new standards. 17 -------------------------------------------------------------------------------- In 2024, we plan to publish our first corporate responsibility and sustainability tear sheet to address the impact of our operations on climate change and discuss material social, governance and environmental issues and our goals related to the same. Any failure or perceived failure to achieve our sustainability goals or to act responsibly with respect to such matters may negatively impact our operations and/or financial condition. While we monitor a broad range of ESG issues, there can be no assurance that we will manage such issues successfully, or that we will successfully meet the expectations of our stakeholders, consumers and employees. Information technology vulnerabilities and cyberattacks on our networks could have a material adverse impact on our business. We rely on information technology ("IT") to manage and conduct business, both internally and externally, with our customers, suppliers and other third parties. Internet transactions involve the transmission and storage of data including customer and supplier business information. Therefore, maintaining the security of computers and other electronic devices, computer networks and data storage resources is a critical issue for us and our customers and suppliers because security breaches could result in reduced or lost ability to carry on our business and loss of, and/or unauthorized access to, confidential information. We have limited personnel and other resources to address information technology reliability and security of our computer networks, and to respond to known security incidents to minimize potential adverse impact. Experienced hackers, cybercriminals and perpetrators of threats may be able to penetrate our network security and misappropriate or compromise our confidential information or that of third parties, create system disruptions or cause shutdowns. These perpetrators of cyberattacks also may be able to develop and deploy viruses, worms, malware and other malicious software programs that attack our information and networks or otherwise exploit any security vulnerabilities of our information and networks. Techniques used to obtain unauthorized access to or sabotage systems change frequently and often are not recognized until after they are launched against a target, and we may be unable to anticipate these techniques or to implement adequate preventative measures. A breach of our IT systems and security measures or those of our third party partners as a result of third party action, malware, employee error, malfeasance or otherwise could materially adversely impact our business and results of operations and expose us to customer, supplier and other third party liabilities. Risks Related to Intellectual Property Failure to protect our intellectual property or infringement of our intellectual property by a third party could have an adverse impact on our financial condition. We rely on a combination of patent, copyright and trademark laws, trade secrets, confidentiality procedures and contractual provisions to protect our proprietary rights. Such means of protecting our proprietary rights may not be adequate because they provide only limited protection or such protection may be prohibitively expensive to enforce. We also enter into confidentiality and non-disclosure agreements with our employees, consultants and many of our customers and vendors, and generally control access to and distribution of our proprietary information. Notwithstanding these measures, a third party could copy or otherwise obtain and use our proprietary information without authorization. We cannot provide assurance that the steps we have taken will prevent misappropriation of our technology and intellectual property, which could negatively impact our business and financial condition. In addition, such actions taken by third parties could divert the attention of our management from the operation of our business. We may be subject to intellectual property infringement claims from third parties that are costly to defend and that may limit our ability to use the disputed technologies. If our technologies are alleged to infringe the intellectual property rights of others, we may be forced to mount a defense to such claims, which may be expensive and time consuming. During the pendency of litigation, we could be prevented from marketing and selling existing products or services and from pursuing research, development or commercialization of new or complimentary products or services. Further, we may be required to obtain licenses to third party intellectual property or be forced to develop or obtain alternative technologies. Our failure to obtain a license to a technology that we may require, or the need to develop or obtain alternative technologies, could significantly and negatively affect our business. Indemnification of third-party licensees of our technologies against intellectual property infringement claims concerning our licensed technology and our products could be financially significant to us. We have agreed to indemnify licensees of our technologies (including Tinuum Group) and purchasers of our products, and we may enter into additional agreements with others under which we agree to indemnify and hold them harmless from losses they 18 -------------------------------------------------------------------------------- may incur as a result of the alleged infringement of third-party rights caused by the use of our technologies and products. Infringement claims, which may be expensive and time-consuming to defend, could have a material adverse effect on our business, operating results and financial condition, even if we are successful in defending ourselves (and the indemnified parties) against them. Our future success depends in part on our ongoing identification and development of intellectual property and our ability to invest in and deploy new products, services and technologies into the marketplace efficiently and cost effectively. The process of identifying customer needs and developing and enhancing products, services and solutions for our customer markets is complex, costly and uncertain. Any failure by us to identify and anticipate changing needs, emerging trends and new regulations could significantly harm our future market share and results of operations. Risk related to tax matters Our ability to utilize our tax assets to offset future income tax liability could be limited from an "ownership change." In general, under IRC Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, ("IRC') a corporation that undergoes an "ownership change" is subject to limitations on its ability to utilize its pre-change net operating losses ("NOLs") and tax credits to offset future taxable income. In general, an ownership change occurs if the aggregate stock ownership of certain stockholders (generally 5% stockholders (as defined in IRC Section 382), applying certain look-through rules) increases by more than 50 percentage points during the testing period (generally a three-year lookback period). An entity that experiences an ownership change generally is subject to an annual limitation on its pre-ownership change tax asset carryforwards. The annual limitation is increased each year to the extent that there is an unused limitation in a prior year. We acquired certain tax assets (the "Legacy Arq Tax Assets") in the Arq Acquisition, totaling approximately $12.5 million. The Legacy Arq Tax Assets are comprised of NOL carryforwards, of which $8.8 million were incurred in the U.S. Further, as of December 31, 2023, we had approximately $86.1 million of general business credit carryforwards (the "Tax Credits"), totaling approximately 77% of consolidated tax assets. Under the IRC and regulations promulgated by the U.S. Treasury Department and the IRS, we may carry forward or otherwise utilize our NOLs and Tax Credits (collectively, "Tax Assets") in certain circumstances to offset current and future federal income tax liabilities, subject to certain requirements and restrictions. However, our ability to use our Tax Assets to offset future federal income tax liability is limited if Legacy Arq or Arq, or both, experience an "ownership change" as discussed above. To the extent that the Tax Assets do not otherwise become limited, we believe that we will have available a significant amount of Tax Assets in future years, and therefore the Tax Assets could be a substantial asset to us. In connection with the Arq Acquisition and PIPE Investment, we issued additional shares of our common stock. We performed an IRC Section 382 analysis as of the Acquisition Date and determined that we had not experienced an "ownership change" as of that date. If we were to experience an "ownership change," it is possible that a significant portion of our Tax Assets could expire before we would be able to use them to offset future federal income tax liability. Prior to the Acquisition Date, Legacy Arq completed numerous equity offerings that resulted in ownership changes. We have not completed a formal IRC Section 382 analysis of Legacy Arq equity changes from its inception through the Acquisition Date, however, we believe that one or more "ownership changes" occurred during this time period as defined under Sections 382 and 383 and that a portion or all the Legacy Arq Tax Assets may subject to an annual limitation. To mitigate the risk of an "ownership change," on May 5, 2017, our board of directors (the "Board") approved the Tax Asset Protection Plan (the "TAPP") and declared a dividend of one preferred share purchase right (each, a "Right") for each outstanding share of our common stock. The TAPP was adopted in an effort to protect stockholder value by attempting to diminish the risk that our ability to use the ADES Tax Credits to reduce potential future federal income tax obligations may become substantially limited (the "Protection Plan"). During the years 2018-2023, we executed amendments to the TAPP (the "TAPP Amendments"), which amended the definition of "Final Expiration Date" under the TAPP to extend the duration of the TAPP and makes associated changes in connection therewith. The most recent TAPP Amendment was approved at our 2023 annual meeting of stockholders and extended the Final Expiration Date to the close of business on December 31, 2024. The TAPP, as amended, is intended to act as a deterrent to any person acquiring beneficial ownership of 4.99% or more of our outstanding common stock without the approval of the Board. Stockholders who beneficially owned 4.99% or more of our outstanding common stock upon execution of the Protection Plan will not trigger the Protection Plan so long as they do not acquire beneficial ownership of additional shares of our common stock. The Board may, in its sole discretion, also exempt any person from triggering the Protection Plan. 19 -------------------------------------------------------------------------------- In connection with the Arq Acquisition and PIPE Investment, we granted a waiver under the TAPP for certain shareholders to acquire more shares of our stock in the future, provided that such acquisition is not expected to, and does not, effect an "ownership change" under IRC Sections 382 and 383. Despite the TAPP, our projections of what will effect an ownership change could be wrong, and with a waiver in place for certain shareholders, there is a risk that we experience an ownership change for purposes of IRC Sections 382 and 383 because of future acquisitions of our common stock. Risks Related to Our Common Stock Our stock price is subject to volatility. The market price of our common stock has experienced substantial price volatility in the past and may continue to do so. The market price of our common stock may continue to be affected by numerous factors, including: a.market perception of the Arq Acquisition; b.actual or anticipated fluctuations in our operating results and financial condition; c.changes in laws or regulations and court rulings and trends in our industry; d.announcements of sales awards; e.changes in supply and demand of components and materials; f.adoption of new tax regulations or accounting standards affecting our industry; g.changes in financial estimates by securities analysts; h.trends in social responsibility and investment guidelines; i.whether we are able and elect to pay cash dividends; j.the continuation of repurchasing shares of common stock under stock repurchase programs; and k.the degree of trading liquidity in our common stock and general market conditions. From January 1, 2023 to December 31, 2023, the closing price of our common stock ranged from $1.25 to $3.66 per share. Stock price volatility over a given period may cause the average price at which we repurchase shares of our common stock to exceed the stock’s price at a given point in time. We believe our stock price should reflect expectations of future growth and profitability. Future dividends are subject to declaration by the Board, and under our current stock repurchase program, we are not obligated to acquire any specific number of shares. If we fail to meet expectations related to future growth, profitability, dividends, stock repurchases or other market expectations, our stock price may decline significantly, which could have a material adverse impact on our ability to obtain additional capital and erode investor confidence, which could further reduce the liquidity of our common stock. We do not expect to repurchase additional shares of our common stock in the near term. Our certificate of incorporation and bylaws contain provisions that may delay or prevent an otherwise beneficial takeover attempt of us. Certain provisions of our certificate of incorporation and bylaws could make it more difficult for a third party to acquire us, even if doing so would be beneficial to our stockholders. These include provisions that: a.Limit the business at special meetings of stockholders to the purpose stated in a notice of the meeting; b.Authorize the issuance of "blank check" preferred stock, which is preferred stock with voting or other rights or preferences that could impede a takeover attempt and that the Board can create and issue without prior stockholder approval; c.Establish advance notice requirements for submitting nominations for election to the Board and for proposing matters that can be acted upon by stockholders at a meeting; and d.Require the affirmative vote of the "disinterested" holders of a majority of our common stock to approve certain business combinations involving an "interested stockholder" or its affiliates, unless either minimum price criteria or procedural requirements are met, or the transaction is approved by a majority of our "continuing directors" (known as "fair price provisions"). 20 -------------------------------------------------------------------------------- These provisions, alone or in combination with each other, may discourage transactions involving actual or potential changes of control, including transactions that otherwise could involve payment of a premium over prevailing market prices to holders of our common stock, or could limit the ability of our stockholders to approve transactions that they may deem to be in their best interest. An increased focus on environmental, social and governance factors by institutional investors may negatively impact our access to capital and the liquidity of our stock price. Some institutional investors have recently adopted ESG investing guidelines that may prevent them from increasing or taking new stakes with companies with exposure to fossil fuels. Additional institutional investors may adopt similar ESG investment guidelines. This could limit both the demand for owning our common stock and/or our access to capital. If such capital is desired, we cannot assure you that we will be able to obtain any additional equity or debt financing on terms that are acceptable to us. Given these emerging trends, liquidity in our common stock and our stock price may be negatively impacted. We require additional funding for our growth plans, and such funding may require us to issue additional shares of our common stock resulting in a dilution of your investment. We estimate our funding requirements in order to implement our growth plans. If the actual funding required to implement growth initiatives should exceed funding estimates significantly, or our funds generated from our operations from such growth initiatives prove insufficient for such purposes, we may need to raise additional funds to meet these funding requirements. These additional funds may be raised by issuing equity or debt securities or by borrowing from banks or other resources. We cannot assure you that we will be able to obtain any additional financing on terms that are acceptable to us, or at all. If we fail to obtain additional financing on terms that are acceptable to us, we may not be able to implement such plans fully. Such financing, even if obtained, may be accompanied by conditions that limit our ability to pay dividends or require us to seek lenders’ consent for payment of dividends, or restrict our ability to operate our business by requiring lender’s consent for certain corporate actions. Further, if we raise additional funds through the issuance of new shares of our common stock, any shareholders who are unable or unwilling to participate in such an additional round of fund raising may suffer dilution of their investment. Certain Legacy Arq shareholders and participants in the PIPE Investment hold a significant portion of the voting power of our common stock. Certain Legacy Arq shareholders and participants in the PIPE Investment hold a significant percentage of our outstanding common stock, and such persons, acting individually or together, could have the ability to exert a substantial influence on actions requiring a stockholder vote. The influence of these significant stockholders may be used in a manner that other stockholders may not support. Any such concentration of ownership may have the effect of delaying certain corporate actions, and may consequently impact the ability of other stockholders to influence the management and policies of the Company. Item 1B. Unresolved Staff Comments None. Item 1C. Cybersecurity Definitions •Cybersecurity incident means an unauthorized occurrence, or a series of related unauthorized occurrences, on or conducted through a registrant's information systems that jeopardizes the confidentiality, integrity, or availability of a registrant's information systems or any information residing therein. •Cybersecurity threat means any potential unauthorized occurrence on or conducted through a registrant's information systems that may result in adverse effects on the confidentiality, integrity, or availability of a registrant's information systems or any information residing therein. •Information systems means electronic information resources, owned, or used by the registrant, including physical or virtual infrastructure controlled by such information resources, or components thereof, organized for the collection, processing, maintenance, use, sharing, dissemination, or disposition of the registrant's information to maintain or support the registrant's operations. 21 -------------------------------------------------------------------------------- Risk Management and Strategy We have established policies and processes for assessing, identifying, and managing material risk from cybersecurity threats, and have integrated these processes into our overall risk management processes. We routinely assess material risks from cybersecurity threats, including any potential unauthorized occurrence on or conducted through our information systems that may result in adverse effects on the confidentiality, integrity, or availability of our information systems or any information residing therein. We engage third parties in connection with our risk assessment processes. We require each third-party service provider to adhere to our internal security policies and certify that it has the ability to implement and maintain appropriate security measures, consistent with all applicable laws, to implement and maintain reasonable security measures in connection with their work with us, and to promptly report any suspected breach of its security measures that may affect our company. These service providers are primarily overseen by our Vice President of Information Technology ("VP of IT") and assist us in monitoring and testing our safeguards, including execution of external penetration testing and ongoing real time vulnerability assessments through our extended detection and response processes to identify cybersecurity threats. We conduct risk assessments in the event of a material change in our business processes that may affect information systems that are vulnerable to such cybersecurity threats through our normal change control processes. These risk assessments include identification of reasonably foreseeable internal and external risks, the likelihood and potential damage that could result from such risks, and the sufficiency of existing policies, procedures, systems, and safeguards in place to manage such risks. Following these risk assessments, we re-design, implement, and maintain reasonable safeguards to minimize identified risks; reasonably address any identified gaps in existing safeguards; and regularly monitor the effectiveness of our safeguards. We devote resources and personnel, including our VP of IT, who reports to our VP of Finance, to manage the risk assessment and mitigation process. As part of our overall risk management, we monitor and test our safeguards and train our employees on the importance of these safeguards. We maintain a formal information security awareness training program for all employees that includes training on matters such as phishing, email security best practices and data protection. Employees also receive random phishing tests at regular intervals to further assess and mitigate overall risk. We maintain a cybersecurity incident response plan to help ensure a timely, consistent and compliant response to actual or attempted cybersecurity incidents impacting the Company. The Response Plan includes (1) detection, (2) analysis, which may include timely notice to our management and audit committee chair, (3) containment, (4) eradication, (5) recovery and (6) post-incident review. We also maintain cybersecurity insurance to manage potential liabilities resulting from specific cybersecurity incidents. It is important to note that although we maintain cybersecurity insurance, there can be no guarantee that our insurance coverage limits will protect us against any future claims or that such insurance proceeds will be paid to us in a timely manner. To date there have been no cybersecurity incidents that have materially affected the Company or its operations. Despite security measures we have implemented, there is always the risk that certain cybersecurity incidents could materially disrupt operational systems limiting our ability to manufacture and deliver products to customers. Governance Our VP of IT has approximately five years of experience in cybersecurity and oversees our cybersecurity policies and processes, including those described in “Risk Management and Strategy” above. Our VP of IT is primarily responsible for assessing and managing our material risks from cybersecurity threats, including monitoring and assessing strategic risk exposure. While management is responsible for the day-to-day management of cybersecurity policies and procedures, our audit committee is tasked with oversight of our risk management process, which includes risks from cybersecurity threats. The processes by which our audit committee is informed about and monitors the Company’s strategy regarding the prevention, detection, mitigation, and remediation of cybersecurity incidents includes the following: Our VP of IT provides quarterly briefings to the audit committee regarding our company’s cybersecurity risks and activities, including any recent cybersecurity incidents and related responses, emerging threats and updates, cybersecurity systems testing, activities of third parties, and the like. Our audit committee and VP of IT provide regular updates to the board of directors on such reports. In the event of an actual cybersecurity threat or incident, management is notified in accordance with the cybersecurity response plan above. 22 -------------------------------------------------------------------------------- Item 2. Properties Office and Facilities We own or lease land and facilities in the following States: Colorado - We lease approximately 24,000 square feet for our corporate headquarters and primary research and development laboratory. Louisiana - We own the Red River Plant, which is located on approximately 61 acres. We also lease approximately 141,000 square feet in various locations that is used for production, distribution and storage. Kentucky - We lease approximately 470 acres in Corbin, Kentucky where we operate the Corbin Facility. Mining As of December 31, 2023, we owned or controlled, primarily through long-term leases, approximately 1,975 acres of coal land for surface mining located in Natchitoches Parish, Louisiana ("Five Forks"). The majority of the Five Forks land is leased for mineral rights and right-of-use purposes that expire at varying dates over the next 30 years and contain options to renew. The remaining land is owned by us. We also have approximately 380 acres of land containing bituminous coal waste at the Corbin Facility for recovery of bituminous coal fines, which is leased through August 31, 2025 and contains options to renew for successive five year terms until all merchantable fines are removed from the premises. Based on current operating assumptions, we intend to renew this lease for an additional five-year term. Based on the materiality and the vertically-integrated company guidelines contained in Regulation S-K of the Securities Act and the Exchange Act, we have concluded that no additional disclosures related to our mining operations are required under this Item. Item 3. Legal Proceedings From time to time, we are involved in various litigation matters arising in the ordinary course of our business. Information with respect to this item may be found in Note 8 "Commitments and Contingencies" to the Consolidated Financial Statements included in Item 8 of this Report. Item 4. Mine Safety Disclosures The statement concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95 to this Report. 23 -------------------------------------------------------------------------------- PART II Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Market for Our Common Stock Effective February 1, 2024, our common stock is quoted on the Nasdaq Global Market under the symbol "ARQ." Prior to that, our common stock was quoted on the Nasdaq Global Market under the symbol "ADES." The trading volume for our common stock is relatively limited. There is no assurance that an active trading market will provide adequate liquidity for our existing stockholders or for persons who may acquire our common stock in the future. Dividends Our most recent dividend payment was in March 2020. We do not intend to declare or pay cash dividends in the foreseeable future. Holders The Company had 875 holders of record of our common stock as of March 5, 2024. The number of holders of record of our common stock is based upon the actual number of holders registered on the books of the Company as of such date and does not include holders of shares that are held in street name by brokers or other nominees. Recent Sales of Unregistered Securities and Use of Proceeds from Registered Securities On February 1, 2023, we entered into subscription agreements with certain persons (the "Subscribers"), which included existing shareholders of Arq Ltd., three of which were appointed to our Board of Directors, pursuant to which the Subscribers subscribed for and purchased 3,842,315 shares of our Common Stock for an aggregate purchase price of $15.4 million and at a price per share of $4.00 (such transaction, the "PIPE Investment"). On July 17, 2023, we entered into a subscription agreement (the "Subscription Agreement") with Mr. Robert "Bob" Rasmus and entities controlled by Mr. Rasmus, in connection with his appointment as our President and Chief Executive Officer. Pursuant to the Subscription Agreement, Mr. Rasmus subscribed for and agreed to purchase 950,000 shares of our common stock, par value $0.001 per share, from the Company for an aggregate purchase price of $1.8 million (at a price per share of approximately $1.90). The securities issued to the Subscribers and Mr. Rasmus under the PIPE Investment and the Subscription Agreement, respectively, were issued pursuant to an exemption from registration under Section 4(a)(2) of the Securities Act, Rule 506 of Regulation D, which is promulgated thereunder, and Regulations S of the Securities Act. We are relying on this exemption from registration based in part on representations made by each of the Subscribers and Mr. Rasmus under their respective subscription agreements. The sale of the securities pursuant to the PIPE Investment has been subsequently registered under the Securities Act on Registration No. 333-276375, which was declared effective on January 31, 2024. The sale of the securities pursuant to the Subscription Agreement (the "Subscriber Shares") has not been registered under the Securities Act or any state securities laws. The Subscriber Shares may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. Purchases of Equity Securities by the Issuer and Affiliated Purchasers Share Repurchases We maintain a program to repurchase up to $20.0 million of shares of our common stock under a stock repurchase program (the "Stock Repurchase Program") through open market transactions at prevailing market prices, of which $7.0 million remained available at December 31, 2023. No purchases were made during the three months ended December 31, 2023. It is unlikely for the foreseeable future that we will resume repurchasing shares of our common stock under the Stock Repurchase Program. Tax Withholding The following table contains information about common shares that we withheld from delivering to employees during the fourth quarter of 2023 to satisfy their respective tax obligations related to stock-based awards. 24 -------------------------------------------------------------------------------- Maximum Number Total Number of (or Dollar Value) Common Shares of Common Shares Purchased as Part that May Yet Be Total Number of Average Price of Publicly Purchased Under Common Shares Paid per Announced Plans the Plans or Period Purchased Common Share or Programs Programs October 1, 2023 to October 31, 2023 — — N/A N/A November 1, 2023 to November 30, 2023 — $ — N/A N/A December 1, 2023 to December 31, 2023 7,969 $ 2.71 N/A N/A Item 6. Reserved 25 -------------------------------------------------------------------------------- Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations Overview We are an environmental technology company and are principally engaged in the sale of consumable air and water treatment solutions primarily based on AC. Our proprietary AC products enable customers to reduce air, soil, and water contaminants, including mercury, PFAS and other pollutants, to help our customers maximize utilization effectiveness and to improve operating efficiencies to meet the challenges of existing and pending air quality, soil, and water regulations. We manufacture and sell AC and other chemicals used to capture and remove contaminants for coal-fired power generation, industrial and water treatment markets, which we collectively refer to as the advanced purification technologies or "APT" market. Our primary products are comprised of AC, which is produced from a variety of carbonaceous raw materials. Our AC products include both PAC and GAC. Additionally, we own the Five Forks Mine, a lignite mine that currently supplies the primary raw material for the manufacturing of our products. In February 2023, we acquired 100% of the equity of the subsidiaries of Arq Limited (hereafter the Arq Limited subsidiaries referred to as "Legacy Arq", and the acquisition itself referred to as the "Arq Acquisition") to secure access to a feedstock, a manufacturing facility and certain patented processes as a means to manufacture additional GAC products for sale into the APT and other markets. With the Arq Acquisition, we now control bituminous coal waste reserves and own a manufacturing facility, both located in Corbin, Kentucky (the "Corbin Facility"), and a process to recover and purify the bituminous coal fines for sale or further conversion to GAC products. Under this manufacturing process, we convert coal waste into a purified, microfine carbon powder known as Arq powderTM ("Arq Powder"). We expect to begin using Arq Powder as a feedstock to begin manufacturing GAC products by the end of 2024 to begin using Arq Powder as a feedstock to produce high-quality GAC products for sale in the APT and other markets. We believe Arq Powder has additional potential for us to access new markets and applications. We expect to secure customer interest in Arq Powder as an additive into other markets, such as components for asphalt. These products utilizing Arq Powder are expected to have a lower carbon footprint compared to similar products utilizing conventional materials. These applications are currently in various stages of proof of concept testing or preliminary customer testing. In February 2024, as part of a larger rebranding, the Company changed its name to Arq, Inc., and on February 1, 2024, our common stock commenced trading under the ticker symbol, "ARQ". Drivers of Demand and Key Factors Affecting Profitability Drivers of demand and current key factors affecting our profitability are sales of our AC products to the APT market. Our operating results are influenced by: (1) changes in our manufacturing production and sales volumes; (2) changes in price and product mix; (3) changes in coal-fired dispatch and electricity power generation sources and (4) changes in demand for contaminant removal within water treatment facilities. Components of Revenue, Expenses and Equity Method Investees The following briefly describes the components of revenue and expenses as presented in the Consolidated Statements of Operations. Descriptions of the revenue recognition policies are included in Note 1 to the Consolidated Financial Statements included in Item 8 of this Report. Revenue and cost of revenue Consumables Our revenue is comprised of the sale of AC products and other chemical-based technology products in the APT market, as well as the sale of other AC products to our largest customer, who services other diverse markets. Consumables cost of revenue Consumables cost of revenue is comprised of all labor, fringe benefits, subcontract labor, additive and coal costs, materials, equipment, supplies, travel costs and any other costs and expenses directly related to the cost of production of consumables. 26 -------------------------------------------------------------------------------- License royalties payable to Tinuum Group In December 2022, the Company and Tinuum Group entered into an agreement (the "Tinuum Group Royalty Agreement") whereby we pay Tinuum Group a royalty (the "Tinuum Group Royalty") for certain of our sales of M-ProveTM products after the expiration of the tax credit program under IRC Section 45 ("Section 45 Tax Credit Program") (beginning January 1, 2022) to certain of the M-45 Facilities. The Tinuum Group Royalty is calculated based on "Net Profit" (as defined in the Tinuum Royalty Agreement) on our sales of M-ProveTM product to certain of the M-45 Facilities. The Tinuum Group Royalty Agreement is for an initial term of five years with automatic renewals of five years unless we and Tinuum Group agree to terminate it. The Tinuum Group Royalty is included in Consumables cost of revenue. Other Operating Expenses Payroll and benefits Payroll and benefits costs include payroll costs, payroll related fringe benefits and stock based compensation expense of research and development, sales and administrative personnel, but exclude such costs related to direct labor that are included in Cost of revenue. Legal and professional fees Legal and professional costs include external legal, audit and consulting expenses. General and administrative General and administrative costs include director fees and expenses, bad debt expense, research and development expense and other general costs of conducting business. Research and development costs provided by third parties, net of reimbursements from cost-sharing arrangements, are charged to expense in the period incurred and are reported in the General and administrative line item in the Consolidated Statements of Operations. Depreciation, amortization, depletion and accretion Depreciation and amortization expense consists of depreciation expense related to property, plant and equipment and the amortization of long-lived intangible assets. Depletion and accretion expense consists of depletion expense related to the depletion of mine development costs and the accretion of mine reclamation liabilities. Other Income (Expense), net Earnings from equity method investments Earnings from equity method investments represent our share of earnings (losses) related to equity method investments, and in 2023, primarily from Tinuum Group. Through December 31, 2021, we had substantial earnings from Tinuum Group and Tinuum Services, LLC ("Tinuum Services"). With the expiration of the tax credit program under IRC Section 45 afforded to producers of refined coal as of December 31, 2021, both Tinuum Group and Tinuum Services commenced winding down their operations related to the Section 45 tax credit program, although we have recognized earnings in both 2022 and 2023 related to residual cash distributions received. Other income (expense) The remaining components of other income (expense) include interest income, interest expense and other miscellaneous items. Results of Operations Presentation of Financial Results For comparison purposes, the following tables set forth our results of operations for the years presented in the Consolidated Financial Statements included in Item 8 of this Report. The year-to-year comparison of financial results is not necessarily indicative of financial results that may be achieved in future years. Our Annual Report on Form 10-K for the year ended December 31, 2023 includes a discussion and analysis of our financial condition and results of operations for the year ended December 31, 2023 compared to the year ended December 31, 2022, disclosed in Item 7 of Part II, "Management’s Discussion and Analysis of Financial Condition and Results of Operations." 27 -------------------------------------------------------------------------------- Year ended December 31, 2023 Compared to Year ended December 31, 2022 Total Revenue and Cost of Revenue A summary of the components of revenue and cost of revenue for the years ended December 31, 2023 and 2022 is as follows: Years Ended December 31, Change (Amounts in thousands except percentages) 2023 2022 ($) (%) Revenue: Consumables $ 99,183 $ 102,987 $ (3,804) (4) % Total revenue $ 99,183 $ 102,987 $ (3,804) (4) % Consumables cost of revenue, exclusive of depreciation and amortization $ 67,323 $ 80,465 $ (13,142) (16) % Consumables revenue and consumables cost of revenue For the years ended December 31, 2023 and 2022, consumables revenue decreased year over year primarily driven by lower volumes sold, which comprised $20.0 million of the total change. Product volumes decreased among power generation customers, primarily due to lower natural gas prices compared to 2022, which contributed to decreased utilization of coal-fired generation and decreased demand for our products. Partially offsetting the decrease was an increase due to improved pricing for our products of approximately $10.6 million, $4.7 million of revenue recognized from the settlement of certain contracts with customers containing minimum quantity purchases ("MQ Contacts") and the impact of favorable product mix of approximately $0.7 million. Consumables gross margin, exclusive of depreciation and amortization, increased for the year ended December 31, 2023 compared to 2022. Driving the increase in gross margin were the impact of the MQ contracts and decreased cost of our feedstock and additives, primarily as a result of decreased production volumes during 2023. Our consumables gross margin was negatively impacted by a decrease in volumes sold. Consumables revenue continues to be affected by electricity demand, driven by seasonal weather and related power generation needs, as well as competitor prices related to alternative power generation sources such as natural gas and renewables. Other Operating Expenses A summary of the components of our operating expenses, exclusive of cost of revenue items (presented above), for the years ended December 31, 2023 and 2022 is as follows: Years Ended December 31, Change (in thousands, except percentages) 2023 2022 ($) (%) Operating expenses: Payroll and benefits $ 15,154 $ 10,540 $ 4,614 44 % Legal and professional fees 9,588 9,455 133 1 % General and administrative 12,641 8,145 4,496 55 % Depreciation, amortization, depletion and accretion 10,543 6,416 4,127 64 % Gain on sale of Marshall Mine, LLC (2,695) — (2,695) * Other (36) 34 (70) (206) % $ 45,195 $ 34,590 $ 10,605 31 % * Calculation not meaningful Payroll and benefits Payroll and benefits expenses increased year over year primarily due to the addition of Legacy Arq employees, which increased expenses by $4.9 million for the year, of which $1.1 million related to severance expense of former executives of Legacy Arq. In addition, for the year ended December 31, 2023, we incurred severance related costs of $1.7 million associated with the termination of three executive employees. These increases were partially offset by a decrease in incentive compensation related 28 -------------------------------------------------------------------------------- to non-Legacy Arq employees for the year ended December 31, 2023 of $1.3 million compared to the corresponding period in 2022. An additional decrease in payroll and benefits was due to retention bonuses with our executive officers and certain other key employees of $1.2 million, which were paid in full in January 2023. Legal and professional fees Legal and professional fees remained flat year over year. General and administrative General and administrative expenses increased for the year ended December 31, 2023 compared to the corresponding period in 2022 as a result of $2.5 million of expenses incurred on behalf of Legacy Arq, which included $1.2 million from rent and occupancy expense from additional leased space. Additional increases period over period of approximately $2.0 million were due to increases in insurance, research and development, travel, recruiting and other outside labor, and director compensation as three new directors were added to the board in connection with the Arq Acquisition. Depreciation, amortization, depletion and accretion Depreciation and amortization expense increased for the year ended December 31, 2023 compared to the corresponding period in 2022 primarily due to depreciation and amortization of approximately $2.8 million from the addition of long-lived assets and intangible assets acquired in the Arq Acquisition. Also contributing to the increase was an increase in Depreciation and amortization expense due to higher production volumes compared to sales volumes which resulted in $1.0 million additional absorption of depreciation in inventory. Gain on sale of Marshall Mine, LLC As discussed above, for the year ended December 31, 2023, we recognized a gain of $2.7 million on the sale of Marshall Mine, LLC. Other Income (Expense), net A summary of the components of our other income (expense), net for the years ended December 31, 2023 and 2022 is as follows: Years Ended December 31, Change (Amounts in thousands, except percentages) 2023 2022 ($) (%) Other income, net: Earnings from equity method investments $ 1,623 $ 3,541 $ (1,918) (54) % Interest expense (3,014) (336) (2,678) 797 % Other 2,630 155 2,475 1,597 % Total other income, net $ 1,239 $ 3,360 $ (2,121) (63) % Earnings from equity method investments The following table presents the equity method earnings by investee for the years ended December 31, 2023 and 2022: Years Ended December 31, Change (in thousands) 2023 2022 ($) (%) Earnings from Tinuum Group $ 1,148 $ 3,455 $ (2,307) (67) % Earnings from Tinuum Services 475 85 390 459 % Earnings from other — 1 (1) (100) % Earnings from equity method investments $ 1,623 $ 3,541 $ (1,918) (54) % 29 -------------------------------------------------------------------------------- Earnings from equity method investments for the year ended December 31, 2023 and 2022 represented cash distributions received from Tinuum Group and Tinuum Services. The decrease was primarily due to Tinuum Group and Tinuum Services continuing to wind down their operations in 2023. Interest expense Interest expense increased for the year ended December 31, 2023 compared to the corresponding period in 2022 primarily due to interest expense of $2.0 million related to the $10 million CFG Loan and interest expense of $0.5 million incurred for the same period related to the $10 million CTB Loan assumed by us in the Arq Acquisition. Other The increase in Other is primarily driven by interest income of $1.8 million generated from the use of cash sweep accounts in 2023. Income tax expense For the year ended December 31, 2023, our reported income tax expense was $0.2 million and was based on an effective rate of (1)%. The difference between our reported income tax expense and the expected federal benefit, as a result of pretax loss recognized for the year ended December 31, 2023, was primarily due to permanent differences related to acquisition-related costs, an increase in the valuation allowance on our deferred tax assets and stock-based compensation. For the year ended December 31, 2022, our reported income tax expense was $0.2 million and was based on an effective rate of (2)%. The difference between our reported income tax expense and the expected federal benefit, as a result of pretax loss recognized for the year ended December 31, 2023, was primarily due to permanent differences related to acquisition-related costs and an increase in the valuation allowance on our deferred tax assets. Accounting for income taxes requires that companies assess whether a valuation allowance should be recorded against their deferred tax asset based on an assessment of the amount of the deferred tax asset that is "more likely than not" to be realized. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that is more likely than not to be realized. We assess a valuation allowance recorded against deferred tax assets at each reporting date. The determination of whether a valuation allowance for deferred tax assets is appropriate requires the evaluation of positive and negative evidence that can be objectively verified. Consideration must be given to all sources of taxable income available to realize the deferred tax asset, including, as applicable, the future reversal of existing temporary differences, future taxable income forecasts exclusive of the reversal of temporary differences and carryforwards, taxable income in carryback years and tax planning strategies. In estimating taxes, we assess the relative merits and risks of the appropriate tax treatment of transactions taking into account statutory, judicial, and regulatory guidance. As of December 31, 2023, we concluded it is more likely than not we will not generate sufficient taxable income within the allowable carryforward periods to realize any of our net deferred tax assets, and fully reserved for such assets as of December 31, 2023. In reaching this conclusion, we primarily considered forecasts of future taxable losses. As of December 31, 2023 and 2022, we had a valuation allowance of $98.8 million and $88.3 million, respectively, on our deferred tax assets. The ability to recognize the remaining deferred tax assets that continue to be subject to a valuation allowance is evaluated on a quarterly basis to determine if there are any significant events that would affect the ability to utilize those deferred tax assets. Our estimate of future taxable income or losses is based on internal projections that consider historical performance, assumptions on future performance and external data. If events are identified that affect our ability to utilize our deferred tax assets, or if additional deferred tax assets are generated, we update our analysis to determine if an increase to a valuation allowance is required. Such an increase could have a material adverse effect on our financial condition and results of operations. Conversely, better than expected results and continued positive results and trends could result in a decrease to a valuation allowance, and any such decreases could have a material positive effect on our financial condition and results of operations. See additional discussion in Note 13 of the Consolidated Financial Statements included in Item 8 of this Report. Tax Assets Through December 31, 2021, we earned substantial tax credits under the Section 45 tax credit program, which expired on December 31, 2021. As of December 31, 2023, we had approximately $86.1 million in Section 45 tax credit carryforwards. 30 -------------------------------------------------------------------------------- In the hypothetical event of an "ownership change," as defined by IRC Sections 382, utilization of general business credits ("Tax Credits") generated prior to the change would be subject to an annual limitation imposed by IRC Section 383 for Tax Credits. In connection with the Arq Acquisition and PIPE Investment, we issued additional shares of our common stock. We performed an IRC Section 382 analysis as of the Acquisition Date and determined that we had not experienced an ownership change as of that date. Prior to the Acquisition Date, Legacy Arq completed numerous equity offerings that resulted in ownership changes. We have not completed a formal IRC Section 382 analysis of Legacy Arq equity changes from its inception through the Acquisition Date, however, we believe that one or more "ownership changes" occurred during this time period as defined under Sections 382 and 383 and that a portion or all the Legacy Arq Tax Assets may subject to an annual limitation. 31 -------------------------------------------------------------------------------- Non-GAAP Financial Measures To supplement our financial information presented in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"), we provide certain supplemental financial measures, including EBITDA and Adjusted EBITDA, which are measurements that are not calculated in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"). EBITDA is defined as earnings before interest, taxes, depreciation and amortization, and Adjusted EBITDA is defined as EBITDA reduced by the non-cash impact of equity earnings from equity method investments and gain on sale of the Marshall Mine, increased by cash distributions from equity method investments, loss on early settlement of a long-term receivable and loss on change in estimate, asset retirement obligations. EBITDA and Adjusted EBITDA should be considered in addition to, and not as a substitute for, net income in accordance with GAAP as a measure of performance. See below for a reconciliation from Net income, the nearest GAAP financial measure, to EBITDA and Adjusted EBITDA. We believe that the EBITDA and Adjusted EBITDA measures are less susceptible to variances that affect the Company's operating performance. We include these non-GAAP measures because management uses them in the evaluation of our operating performance, and believe they help to facilitate comparison of operating results between periods. We believe the non-GAAP measures provide useful information to both management and users of the financial statements by excluding certain expenses, gains, and losses which can vary widely across different industries or among companies within the same industry and may not be indicative of core operating results and business outlook. 32 -------------------------------------------------------------------------------- EBITDA and Adjusted EBITDA The following table reconciles net loss, our most directly comparable as-reported financial measure calculated in accordance with GAAP to EBITDA, (EBITDA Loss), (Adjusted EBITDA Loss) and Adjusted EBITDA. Year ended December 31, 2023 2022 Net loss (1) $ (12,249) $ (8,917) Depreciation, amortization, depletion and accretion 10,543 6,416 Amortization of Upfront Customer Consideration 508 508 Interest expense, net 1,168 97 Income tax expense 153 209 EBITDA (EBITDA Loss) 123 (1,687) Cash distributions from equity method investees 1,623 5,933 Equity earnings (1,623) (3,541) Gain on sale of Marshall Mine, LLC (2,695) — Loss (gain) on change in estimate, asset retirement obligation (37) 34 Loss on early settlement of an account receivable — 535 Adjusted (EBITDA Loss) EBITDA $ (2,609) $ 1,274 (1) Included in Net loss for the year ended December 31, 2023 and 2022 was $4.9 million and $5.0 million, respectively, of transaction and integration costs incurred related to the Arq Acquisition. Additionally, for the year ended December 31, 2023, Net loss included $4.9 million of Legacy Arq payroll and benefit costs and $1.7 million of severance expense related to three executive employees. Liquidity and Capital Resources Current Resources and Factors Affecting Our Liquidity As of December 31, 2023, our principal future sources of liquidity included: •cash on hand, excluding restricted cash of $8.8 million primarily pledged as collateral under a surety bond agreement; and •our operations For the year ended December 31, 2023, our principal uses of liquidity included: •our business operating expenses; •capital and spare parts expenditures; •payments on our lease obligations; •payments for reclamation associated with the Five Forks Mine; and •payment required under the sale of Marshall Mine, LLC. On February 1, 2023, in connection with the Arq Acquisition, we closed the PIPE Investment for an aggregate purchase price of $15.4 million. Further, on February 1, 2023 we entered into the CFG Loan Agreement for $10.0 million, of which we received $8.5 million net proceeds. 33 -------------------------------------------------------------------------------- Tinuum Group and Tinuum Services Distributions The following table summarizes the cash distributions from our equity method investments for the years ended December 31, 2023 and 2022: Year ended December 31, (in thousands) 2023 2022 Tinuum Group $ 1,148 $ 3,455 Tinuum Services 475 2,476 Other — 2 Distributions from equity method investees $ 1,623 $ 5,933 Cash distributions from Tinuum Group and Tinuum Services for 2023 decreased by $4.3 million compared to 2022 primarily due to Tinuum Group and Tinuum Services ceasing material operations as of December 31, 2021. Cash Flows Cash and restricted cash decreased from $76.4 million as of December 31, 2022, to $54.2 million as of December 31, 2023, a decrease of $22.3 million. The following table summarizes our cash flows for the years ended December 31, 2023 and 2022, respectively: Years Ended December 31, (in thousands) 2023 2022 Change Cash provided by (used in): Operating activities $ (16,653) $ (6,061) $ (10,592) Investing activities (28,535) (4,608) (23,927) Financing activities 22,909 (1,679) 24,588 Net change in Cash and Restricted Cash $ (22,279) $ (12,348) $ (9,931) Cash flows from operating activities Cash flows used in operating activities for the year ended December 31, 2023 was $16.7 million compared to cash flows used in operating activities of $6.1 million for the year ended December 31, 2022. The increase in cash used in operating activities was primarily due to the following: (1) an increase in net loss of $3.3 million year over year; (2) a $2.7 million gain on the sale of the Marshall Mine, LLC; (3) a decrease in Distributions from equity method investees, return on investment of $2.3 million year over year; and (4) a net decrease in working capital of $8.9 million primarily as a result of significant payments made in 2023 on accounts payable and accrued expenses assumed in the Arq Acquisition. Offsetting the net increase in cash flows used in operating activities year over year were (1) an increase in Depreciation, amortization, depletion and accretion of $4.1 million; and (2) a decrease in Earnings from equity method investments of $1.9 million. Cash flows from investing activities Cash flows used in investing activities for the year ended December 31, 2023 was $28.5 million compared to cash flows used in investing activities of $4.6 million for the year ended December 31, 2022. The increase was primarily due to an increase in acquisition of property, equipment and intangibles, net, of $18.6 million primarily related to acquisition costs related to the Arq Acquisition, a payment of $2.2 million related to the disposal of Marshall Mine, LLC, increased mine development costs of $2.1 million, and a decrease in distributions from equity earnings in excess of cumulative earnings of $2.0 million. Offsetting the net increase in cash flows used in investing activities year over year was $2.2 million cash acquired as part of the Arq Acquisition. Cash flows from financing activities Cash flows provided by (used in) financing activities for the year ended December 31, 2023 increased by $24.6 million compared to the year ended December 31, 2022 primarily due to proceeds from common stock issued of $16.2 million, 34 -------------------------------------------------------------------------------- including $1.0 million of proceeds from common stock issued to related parties, and net proceeds from the issuance of the CFG Loan Agreement of $8.5 million. Material Cash Requirements Our ability to continue to generate sufficient cash flow required to meet ongoing operational needs and obligations depends upon several factors. These include executing on our contracts and initiatives and increasing our share of the market for APT consumables, including expanding our overall AC business into additional adjacent markets and increasing our gross margin from improving our customer and product mix. Based on current operating levels, we expect that our cash on hand as of December 31, 2023 will provide sufficient liquidity to fund operations for the next 12 months. Capital expenditures We have targeted the end of 2024 for the completion of our Red River Plant expansion that is necessary to commence production of our new GAC products. To meet this target, we will incur substantial capital spend in excess of our originally forecasted amount for additional equipment, labor, and project costs. The Company anticipates financing the timely completion of the project funded with cash on hand, cash generation, ongoing cost reduction initiatives, potential customer prepayments for GAC contracts, and a planned refinancing and potential expansion of our term loan. If we are not able to secure additional financing, the project timeline for our Red River Plant expansion may be delayed beyond the end of 2024. During 2024, we expect to spend between $45 and $50 million on the Red River Plant expansion, depending on the pace of the project, as well as between $5 and $10 million to complete our commissioning of the Corbin Facility. Capital expenditures planned for 2024 are dependent on many factors, including the ability to raise additional funding and approval of certain environmental permits, both of which may impact the timing and amount of capital expenditures. Surety Bonds As of December 31, 2023, we had outstanding surety bonds with regulatory commissions totaling $11.2 million primarily related to the Five Forks Mine and the Corbin Facility. As of December 31, 2023, and as required by our surety bond provider, we held restricted cash of $8.5 million pledged as collateral related to performance requirements required under a reclamation contract for the Five Forks Mine and the Corbin Facility. We expect that the obligations secured by these surety bonds will be performed in the ordinary course of business and in accordance with the applicable contractual terms. To the extent that the obligations are performed, the related surety bonds may be released and collateral requirements may be reduced. However, in the event any surety bond is called, our indemnity obligations could require us to reimburse the surety bond provider. Long Term Requirements For a discussion of our long-term cash requirements, see Item 8. Note 6 of this Report. Contractual Obligations Contractual obligations as of December 31, 2023 are as follows: Payment Due by Period Less than 1 (in thousands) Total year 1-3 years 4-5 years After 5 years CFG Loan $ 12,199 $ — $ — $ 12,199 $ — CTB Loan 13,413 1,110 2,220 2,220 7,863 Finance lease obligations 3,666 2,274 1,307 85 — Operating lease obligations 18,559 3,139 5,747 2,595 7,078 $ 47,837 $ 6,523 $ 9,274 $ 17,099 $ 14,941 The table above excludes our asset retirement obligation ("ARO") related to reclamation of the Five Forks Mine, as the timing and amount of payments to satisfy the ARO are uncertain and are based on numerous factors including, but not limited to, the expected closure date of the Five Forks Mine. As of December 31, 2023, our Consolidated Balance Sheet reflects a liability for AROs of $6.2 million. Additionally, the table above excludes construction costs related to the Red River Plant expansion and Corbin Facility commissioning referred to under "Capital Expenditures" caption above, as the timing and amount of payments 35 -------------------------------------------------------------------------------- to satisfy these obligations are conditional and based on numerous factors including, but not limited to, the pace of construction activities and the timing of mechanical completion of the Red River Plant expansion and commissioning activities at the Corbin Facility. Critical Accounting Policies and Estimates Our significant accounting policies are discussed in Note 1 to the Consolidated Financial Statements included in Item 8 of this Report. In presenting our financial statements in conformity with GAAP, we are required to make estimates and assumptions that affect the amounts reported therein. Several of the estimates and assumptions we are required to make relate to matters that are inherently uncertain as they pertain to future events. Our estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions. We believe that the accounting estimates discussed below are critical to understanding our historical and future performance, as these estimates relate to the more significant areas involving management’s judgments and estimates. Business Combinations, including asset acquisitions We apply the acquisition method to acquisitions of both businesses and assets and allocate the purchase price to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. The purchase price allocation process requires us to make significant estimates and assumptions with respect to assets acquired and liabilities assumed. We believe the assumptions and estimates we make are reasonable, they are based in part on historical experience, market conditions and information obtained from management of the acquired company or group of assets and are inherently uncertain. Examples of critical estimates in valuing certain of long-lived assets, including intangible assets, we have acquired or may acquire in the future include but are not limited to: •future expected cash flows from revenue; •the acquired company’s developed technology as well as assumptions about the period of time the acquired developed technology will continue to be used in the combined company's product portfolio; •the expected use and useful lives of the acquired assets; and •valuation methods and discount rates used in estimating the values of the assets acquired and liabilities assumed. Carrying value of long-lived assets and intangibles We review and evaluate our long-lived assets and intangibles for impairment at least annually, or more frequently when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. An impairment loss is measured and recorded for long-lived assets and intangibles based on the excess of their carrying amounts over their estimated fair values. Fair value is typically determined through the use of an income approach utilizing estimates of discounted pretax future cash flows or a market approach utilizing recent transaction activity for comparable assets. Asset Retirement Obligations Accounting for AROs requires us to make estimates of future costs unique to a specific mining operation that we will incur to complete the reclamation and remediation work required to comply with existing laws and regulations. Any such changes in future costs, the timing of reclamation activities, scope or the exclusion of certain costs not considered reclamation and remediation costs could materially impact the amounts charged to earnings for reclamation and remediation. Additionally, future changes to environmental laws and regulations could increase the scope of reclamation and remediation work required. Reclamation costs related to AROs are allocated to expense over the life of the related mine assets and are periodically adjusted to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. Remediation costs are accrued based on management’s best estimate of the costs expected to be incurred. Such cost estimates may include ongoing care, maintenance and monitoring costs. Reclamation obligations are based on the timing of estimated spending for an existing environmental disturbance. We review, on at least an annual basis, the future expected costs and the timing of such costs for AROs. 36 -------------------------------------------------------------------------------- Income Taxes We account for income taxes under the asset and liability method, which requires judgment in determining income tax expense and the related balance sheet amounts. This includes estimating and analyzing historical and projected future operating results, the reversal of taxable temporary differences, tax planning strategies, and the ultimate outcome of uncertain income tax positions. Actual income taxes paid may vary from estimates depending on changes in income tax laws, actual results of operations, state apportionment and, if applicable, final audits of tax returns by taxing authorities. Tax assessments may arise several years after tax returns have been filed. Changes in the estimates and assumptions used for calculating income tax expense and potential differences in actual results from estimates could have a material impact on our results of operations and financial condition. We recognize deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies and results of recent operations. We establish a valuation allowance against our deferred tax assets when, based upon the weight of all available evidence, we believe it is more likely than not that some portion or all of the deferred tax assets will not be realized. In making this determination, we consider the relative impact of all of the available positive and negative evidence regarding future sources of taxable income and tax planning strategies. However, there could be a material impact to our effective tax rate if there is a significant change in our estimates of future taxable income. If and when our estimates change, or there is a change in the value of deferred tax assets or liabilities warranting the need to reassess the realizability of deferred tax assets, we adjust a valuation allowance through the provision for income taxes in the period in which this determination is made. Refer to Note 13 of our Consolidated Financial Statements included in Item 8 of this Report for additional information regarding our deferred tax assets and liabilities. Recently Issued Accounting Standards Refer to Note 1 of the Consolidated Financial Statements included in Item 8 of this Report for information regarding recently issued accounting standards. 37 -------------------------------------------------------------------------------- Item 7A. Quantitative and Qualitative Disclosures About Market Risk The information under this Item is not required to be provided by smaller reporting companies. 38 -------------------------------------------------------------------------------- Item 8. Financial Statements and Supplementary Data Arq, Inc. Index to Financial Statements Arq, Inc. Consolidated Financial Statements: Report of Independent Registered Public Accounting Firm (Moss Adam LLP, Denver, Colorado, PCAOB ID: 659 ) 40 Consolidated Balance Sheets as of December 31, 2023 and 2022 42 Consolidated Statements of Operations for the years ended December 31, 2023 and 2022 43 Consolidated Statements of Changes in Stockholders’ Equity for the years ended 44 December 31, 2023 and 2022 Consolidated Statements of Cash Flows for the years ended December 31, 2023 and 2022 45 Notes to Consolidated Financial Statements 47 39 -------------------------------------------------------------------------------- Report of Independent Registered Public Accounting Firm To the Shareholders and the Board of Directors of Arq, Inc. and Subsidiaries Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Arq, Inc. and Subsidiaries (the Company) as of December 31, 2023 and 2022, the related consolidated statements of operations, changes in stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2023 and 2022, and the consolidated results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Business Combination – Valuation of Acquired Property, Plant, and Equipment and Developed Technology Intangible Asset As described in Notes 1 and 2 to the consolidated financial statements, in February 2023, the Company acquired 100% of the equity of the subsidiaries of Arq Ltd. (the “Arq Acquisition”) in exchange for total consideration of $31.2 million. The Company accounted for the Arq Acquisition as an acquisition of a business and recorded the assets acquired and liabilities assumed at their respective fair values, including $39.2 million of property, plant, and equipment, and a $7.7 million developed technology intangible asset. Management estimated the fair value of the acquired property, plant and equipment using a combination of valuation methodologies, including the cost and market approaches and the fair value of the developed technology intangible asset using an income approach. The significant assumptions used by management in determining the fair value of the acquired property, plant and equipment primarily included estimated replacement costs and sales prices of the acquired assets as well as the estimated useful lives of the acquired assets. The significant assumptions used by management in determining the fair value of the developed technology intangible asset included the Company’s best estimate of projected financial information, including revenues, growth rates, production ramp-up and capacity, and cost of revenue as well as discount and royalty rates. 40 -------------------------------------------------------------------------------- The principal considerations for our determination that performing procedures relating to the valuation of the acquired property, plant and equipment and developed technology intangible asset relating to the Arq Acquisition is a critical audit matter are (i) the significant judgment by management when determining the significant assumptions used in projecting future financial performance of the acquired business; (ii) especially challenging and subjective auditor judgment involved when performing procedures and evaluating management’s significant assumptions related to revenue and its growth rate, production ramp-up and capacity, and cost of revenue, and the discount and royalty rates utilized; and (iii) involving the use of professionals with specialized skill and knowledge. The primary procedures we performed to address this critical audit matter included: –Obtaining and reading the Securities Purchase Agreement to develop an understanding of the Arq Acquisition. –Evaluating management’s process for determining the fair value of the acquired property, plant and equipment and developed technology intangible asset, including the appropriateness of the valuation methods used. –Testing the completeness and accuracy of the underlying data used in the valuation models. –Evaluating the reasonableness of the significant assumptions used by management related to projected financial information, which primarily related to production ramp-up and capacity, revenue growth, cost of revenues and the discount and royalty rates. Specifically, when evaluating the assumptions related to production ramp-up and capacity and revenue growth rates, we compared the assumptions to industry and market trends, along with updated management forecasts, to evaluate the reasonableness of management’s estimates as of the date of the transaction. –Utilizing professionals with specialized skill and knowledge to assist in evaluating the appropriateness of the valuation models used and the reasonableness of certain significant assumptions including estimated replacement costs and sales prices as well as discount and royalty rates.

-------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements Note 1 - Summary of Operations and Significant Accounting Policies Nature of Operations Arq Inc. ("Arq" or the "Company", formerly known as Advanced Emissions Solutions, Inc. ("ADES")) is a Delaware corporation with its principal office located in Greenwood Village, Colorado, manufacturing, mining and logistic operations located in Louisiana and mining and manufacturing operations in Kentucky. The Company is an environmental technology company and is principally engaged in the sale of consumable air, water, and soil treatment solutions including activated carbon ("AC") and chemical technologies. The Company's proprietary AC products enable customers to reduce air, water, and soil contaminants, including mercury, per and polyfluoroalkyl substances ("PFAS") and other pollutants, to help our customers meet the challenges of existing and pending air quality and water regulations. The Company manufactures and sells AC and other chemicals used to capture and remove contaminants for coal-fired power generation, industrial, municipal water and air, water, and soil treatment and remediation markets (collectively, the advanced purification technologies or "APT" market). In February 2023, the Company acquired 100% of the equity of the subsidiaries of Arq Limited (the "Arq Acquisition," and hereafter the Arq Limited subsidiaries referred to as "Legacy Arq") to secure access to a feedstock, a manufacturing facility and certain patented processes as a means to manufacture additional granular activated carbon ("GAC") products for sale into the APT and other markets. With the Arq Acquisition, the Company now controls bituminous coal waste reserves and owns a manufacturing facility, both located in Corbin Kentucky (the "Corbin Facility"), and a process to recover and purify the bituminous coal fines for sale or further conversion to GAC products. Under this manufacturing process, the Company expects to be able to convert bituminous coal waste into a purified, microfine carbon powder known as Arq powderTM ("Arq Powder"). See further discussion of the Arq Acquisition in Note 2. Principles of Consolidation The Consolidated Financial Statements include accounts of wholly-owned subsidiaries and variable interest entities ("VIEs") in which the Company is the primary beneficiary. All significant intercompany balances and transactions have been eliminated in consolidation. All investments in partially owned entities for which the Company has the ability to exercise significant influence and holds a 20% or greater ownership interest based on the legal form of the Company's ownership percentage are accounted for using the equity method and are included in the Other long-term assets, net line item in the Consolidated Balance Sheets. As of December 31, 2023, the Company holds equity interests of 42.5% and 50.0% in Tinuum Group, LLC ("Tinuum Group") and Tinuum Services, LLC ("Tinuum Services"), respectively. Cash and restricted cash Cash consists of cash on hand and bank deposits. Restricted cash is primarily comprised of posted cash collateral required under a surety bond contract related to a lignite mine in Louisiana (the "Five Forks Mine") and the Corbin Facility. Concentration of credit risk As of December 31, 2023, the Company holds cash that exceed the Federal Deposit Insurance Corporation ("FDIC") limits (currently $250 thousand) at two financial institutions. If a financial institution was unable to perform its obligations, the Company would be at risk regarding the amount of cash held in excess of the FDIC limits. Fair value measurements The carrying amounts of our cash, restricted cash, accounts receivable, accounts payable and other current liabilities approximate fair value as recorded due to the short-term nature of these instruments. 47 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements Receivables, net Receivables, net are recorded at net realizable value, which includes an appropriate allowance for estimated uncollectible amounts to reflect any loss anticipated on the receivables. Increases and decreases in the allowance for doubtful accounts are established based upon changes in the credit quality of receivables and are included as a component of the General and administrative line item in the Consolidated Statements of Operations. The allowance for doubtful accounts is based on historical experience, general economic conditions and the credit quality of specific accounts and was not material as of December 31, 2023 and 2022. Inventories, net The cost of inventory is determined using the average cost method. Inventories, net are stated at the lower of average cost or net realizable value and consist principally of raw materials and finished goods related to the Company's AC products. Inventories are periodically reviewed for both potential obsolescence and potential declines in anticipated selling prices. The Company makes assumptions about the future demand for and market value of the inventory and estimates the amount of any obsolete, unmarketable, slow moving or overvalued inventory. The composition of Inventories is included in Note 3. Intangible Assets Intangible assets consist of customer relationships, patents, and developed technology. The Company has developed technologies resulting in patents being granted by the U.S. Patent and Trademark Office or other regulatory offices. Legal costs associated with securing the patent are capitalized and amortized over the legal or useful life beginning on the patent filing date. The following table details the components of the Company's intangible assets: As of December 31, 2023 2022 Weighted Average Remaining Amortization Net of Accumulated Net of Accumulated (in thousands, except years) Period (in years) Cost Amortization Cost Amortization Customer relationships 0.0 $ 835 $ — $ 835 $ 226 Patents 11.1 1,600 520 1,490 456 Developed technology 19.1 8,307 7,379 607 165 Total $ 10,742 $ 7,899 $ 2,932 $ 847 Included in the Consolidated Statements of Operations is amortization expense related to intangible assets of $0.8 million and $0.5 million for the years ended December 31, 2023 and 2022, respectively. The estimated future amortization expense for existing intangible assets as of December 31, 2023 is expected to be approximately $0.4 million for the year ended December 31, 2024 and each of the four succeeding fiscal years. Investments The investments in entities in which the Company does not have a controlling interest (financial or operating), but where it has the ability to exercise significant influence over operating and financial policies, are accounted for using the equity method of accounting. Whether or not the Company exercises significant influence with respect to an investee depends on an evaluation of several factors including, among others, representation on the investee company’s board of directors and the Company's ownership percentage. Under the equity method of accounting, an investee company’s financial statements are not consolidated in the Company’s Consolidated Balance Sheets and Consolidated Statements of Operations; however, the Company’s share of the earnings or losses of the investee is reported in the "Earnings from equity method investments" line item in the Consolidated Statements of Operations, and the Company’s carrying value in an equity method investee is reported in the "Other long-term assets, net" line in the Consolidated Balance Sheets. The Company recognizes equity earnings from equity method investments based on its percentage ownership in the investee. The Company recognizes distributions received in excess of the carrying value of an equity method investment as equity 48 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements method earnings in the period the distributions occur to the extent that the Company has not guaranteed any obligations of the investee or is not contractually required to provide additional funding to the investee. Subsequent earnings from investees where the Company has recognized earnings from distributions in excess of the carrying value of the equity method investment are recognized for the excess of cumulative earnings over previously recognized earnings from distributions. Additionally, when the Company's carrying value in an equity method investment is zero, and the Company has not guaranteed any obligations of the investee or is not required to provide additional funding to the investee, the Company will not recognize its share of any reported losses by the investee until future earnings are generated to offset previously unrecognized losses. Therefore, equity income (loss) reported in the Company's Consolidated Statements of Operations for certain equity method investees may differ from a mathematical calculation of net income or loss attributable to its equity interest based on the percentage ownership of the Company's equity interest and the net income or loss attributable to equity owners as shown in the investee's statements of operations. Distributions from equity method investees are reported in the Consolidated Statements of Cash Flows as "return on investment" in Operating cash flows until such time as the carrying value in an equity method investee is reduced to zero. Thereafter, such distributions are reported as "distributions in excess of cumulative earnings" in Investing cash flows. Investments in partially-owned subsidiaries for which the Company has less than 20% ownership are accounted for in accordance with accounting guidance applicable to equity investments that do not qualify for the equity method of accounting. The Company evaluates these types of investments for changes in fair value and, if there is change, recognizes the change in the Consolidated Statement of Operations. If no such events or changes in circumstances have occurred related to these types of investments, the fair value is estimated only if practicable to do so. Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation and include leasehold improvements. Depreciation on assets is computed using the straight-line method over the lesser of the estimated useful lives of the related assets or the lease term (ranging from 1 to 31 years). Maintenance and repairs that do not extend the useful life of the respective asset are charged to operating expenses as incurred. When assets are retired, or otherwise disposed of, the property accounts are relieved of costs and accumulated depreciation and any resulting gain or loss is credited or charged to income. The Company periodically evaluates the recoverability of the carrying value of property, plant and equipment for impairment. Amortization of right of use assets under finance lease is included in depreciation expense and is calculated using the straight-line method over the term of the lease. Leases The Company records a right of use ("ROU") asset and related liability under a contract or part of a contract when it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Control over the use of an identified asset occurs when an entity has both the right to obtain substantially all of the economic benefits from the use of an identified asset and the right to direct the use of that identified asset. The determination of whether a contract contains a lease may require significant assumptions and judgments. For all classes of underlying assets, the Company does not separate nonlease components from lease components and accounts for each separate lease component and the nonlease components associated with that lease component as a single lease component. The Company records lease liabilities and related ROU assets for all leases that have a term of greater than one year. For short-term leases (leases with terms of less than one year), the Company expenses lease payments on a straight-line basis over the lease term. Variable lease payments represent payments made by a lessee for the right to use an underlying asset that vary because of changes in facts or circumstances occurring after the commencement date of a lease other than the passage of time. Variable lease payments that are based on an index or rate, calculated by using the index or rate that exists on the lease commencement date, are included in the measurement of a lease liability. Certain of the Company’s operating leases for office facilities contain variable lease components that are not based on an index or rate, and the Company recognizes these payments as variable lease expense in the period in which the obligation for those payments is incurred. The Company calculates lease liabilities based on the present value of lease payments discounted by the rate implicit in the lease or, if not readily determinable, the Company’s incremental borrowing rate. Finance lease liabilities are subsequently measured by increasing the carrying amount to reflect interest expense on the finance lease liability and reducing the carrying amount of the lease liability to reflect lease payments made during the period. Interest 49 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements on finance lease liabilities is determined in each period during the lease term as the amount that produces a constant periodic discount rate on the remaining balance of the lease liability. ROU assets under finance leases are amortized over the remaining lease term on a straight-line basis. Interest expense related to finance lease liabilities and amortization of ROU assets under finance leases are included in the "Interest expense" and "Depreciation, amortization, depletion and accretion" line items, respectively, in the Consolidated Statements of Operations. Operating lease liabilities are subsequently measured at the present value of the lease payments not yet paid, discounted using the discount rate for the lease established at the inception date of the lease. ROU assets under operating leases are subsequently measured at the amounts of the related operating lease liability, adjusted for, as applicable, prepaid or accrued lease payments, the remaining balance of any lease incentives received, unamortized initial direct costs and impairment. Lease expense from operating leases is recognized as a single lease cost over the remaining lease term on a straight-line basis. Variable lease payments not included in operating lease liabilities are recognized as expense in the period in which the obligation for those payments is incurred. Lease expense from operating leases is included in the "General and administrative" and "Consumables Cost of revenue, excluding depreciation and amortization" line items in the Consolidated Statements of Operations. Other Assets Mine Development Costs Mine development costs are related to the Five Forks Mine and are stated at cost less accumulated depletion and include acquisition costs, the cost of other development work and mitigation costs. Costs are amortized over the estimated life of the related mine reserves, which as of December 31, 2023 is estimated to be 14 years. The Company performs an evaluation of the recoverability of the carrying value of mine development costs to determine if facts and circumstances indicate that their carrying value may be impaired and if any adjustment is warranted. Mine development costs are reported in the "Other long-term assets, net" line item in the Consolidated Balance Sheets. Spare Parts Spare parts include critical spares required to support plant operations. Parts and supply costs are determined using the lower of cost or estimated replacement cost. Parts are recorded as maintenance expenses or capitalized in the period in which they are consumed or put into use. Spare parts are reported in the "Other long-term assets, net" line item in the Consolidated Balance Sheets. Revenue Recognition The Company recognizes revenue from a contract with a customer when a performance obligation under the terms of a contract with a customer is satisfied, which is when the customer controls the promised goods or services that are transferred in satisfaction of the performance obligation. Revenue is measured as the amount of consideration that is expected to be received in exchange for transferring goods or providing services, and the transaction price is generally fixed and generally does not contain variable or noncash consideration. In addition, the Company’s contracts with customers generally do not contain customer refund or return provisions or other similar obligations. Transfer of control and satisfaction of performance obligations are further discussed below. The Company uses estimates and judgments in determining the nature and timing of satisfaction of performance obligations, the standalone selling price ("SSP") of performance obligations and the allocation of the transaction price to multiple performance obligations, if any. The Company’s revenue component is Consumables. Consumables The Company is principally engaged in the sale of consumable products that utilize AC and chemical-based technologies to a broad range of customers, including coal-fired utilities, industrial and water treatment plants, and other diverse markets. The sale of consumable products is comprised of a single performance obligation and is recognized at the point in time when control transfers and the Company's obligation has been fulfilled, which is when the product is shipped or delivered to a customer. Performance obligations for the sale of consumable products do not extend beyond one year. 50 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements Certain contracts with customers require the customers to purchase minimum quantities over the contractual period ("MQ Contracts"). Under these MQ Contracts, the Company reserves the right to bill a customer for any shortfall in the actual quantity purchases and minimum quantity purchases as of the end of the contractual period. The Company recognizes revenue on MQ Contracts based on the satisfaction of all three of the following criteria: (1) the likelihood of a customer not meeting its MQ contract obligations is probable, (2) the amount of the shortfall can be quantified and (3) the Company elects to exercise it right to enforce the billing of the shortfall at some point during the contractual period through a billing subsequent to the contractual period. The determination of when all three criteria are satisfied requires significant judgment. The Company performs shipping and handling activities through the use of third-party shippers and such activities occur prior to a customer obtaining control of goods. As such, the Company accounts for these activities as fulfillment activities and not as separate performance obligations. Shipping and handling costs incurred by the Company in delivering products to customers are billed to customers and are included in the transaction price and included in the "Revenue - Consumables" line item in the Consolidated Statements of Operations. Costs for shipping and handling activities incurred by the Company are included in the "Consumables cost of revenue, excluding depreciation and amortization" line item in the Consolidated Statements of Operations. Practical Expedients and Exemptions The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. Sales and other taxes that are collected concurrently with revenue-producing activities are excluded from revenue. The Company generally expenses sales commissions when incurred, as the amortization period of the asset that the Company would have recognized is one year or less. These costs are recorded in sales and marketing expenses in the "General and administrative" line item in the Consolidated Statements of Operations. Consumables Cost of Revenue Consumables cost of revenue includes all labor, fringe benefits, subcontract labor, additive and coal costs, materials, equipment, supplies, travel costs and any other costs and expenses directly related to the Company’s production of revenue. License Royalties Payable to Tinuum Group In December 2022, the Company and Tinuum Group entered into an agreement (the "Tinuum Group Royalty Agreement") whereby the Company agreed to pay Tinuum Group a royalty (the "Tinuum Group Royalty") on sales of M-ProveTM to certain power plants where Tinuum Group had operated refined coal facilities (the "M-45 Facilities") prior to the expiration of the Section 45 Tax Credit Program on December 31, 2021. Amounts due under the Tinuum Group Royalty Agreement commenced on January 1, 2022. The Tinuum Group Royalty is calculated based on "Net Profit" (as defined in the Tinuum Royalty Agreement) on the Company's sales of M-ProveTM product to the M-45 Facilities. The Tinuum Group Royalty Agreement is for an initial term of five years with automatic renewals of five years unless the Company and Tinuum Group agree to terminate it. The Tinuum Group Royalty is included in Cost of revenue in the Consolidated Statements of Operations. Payroll and Benefits Payroll and benefits costs include payroll costs, payroll related fringe benefits and stock based compensation expense of research and development, sales and administrative personnel, but exclude such costs related to direct labor that are included in Cost of revenue. Payroll and benefits costs include direct payroll, personnel related fringe benefits, sales and administrative staff labor costs and stock compensation expense. Payroll and benefits costs exclude direct labor included in Cost of revenue. Legal and Professional Legal and professional costs include external legal, audit and consulting expenses. General and Administrative General and administrative costs include director fees and expenses, rent, insurance and occupancy-related expenses, bad debt expense, impairments, research and development and other general costs of conducting business. 51 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements Research and Development Research and development costs are charged to expense in the period incurred and are reported within the "Payroll and Benefits" and "General and administrative" line items in the Consolidated Statements of Operations. For the years ended December 31, 2023 and 2022, the Company recorded total research and development costs of $3.3 million and $2.1 million, respectively. Asset Retirement Obligations Asset retirement obligations ("ARO") are comprised of mine reclamation activities required under agreements related primarily to the Five Forks Mine and a coal waste site adjacent to the Corbin Facility (the "Corbin ARO") and are recognized when incurred and recorded as liabilities at fair value. An ARO is accreted over time through periodic charges to earnings. An ARO asset is depreciated over its estimated remaining life. Accounting for AROs requires the Company to estimate future costs unique to a specific mining operation that the Company expects to incur to complete the reclamation and remediation work required to comply with existing laws and regulations. AROs are periodically adjusted to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. On an annual basis, unless otherwise deemed necessary, the Company reviews its estimates and assumptions of its AROs. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred income taxes are provided for temporary differences between the financial reporting basis and tax basis of the Company's assets and liabilities and are tax-effected using enacted tax rates in effect for the year in which the temporary differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in operations in the period that includes the enactment date. The Company maintains valuation allowances where it is more likely than not that all or a portion of deferred tax assets will not be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. The Company records uncertain tax positions on the basis of a two-step process whereby (1) the Company determines whether it is more-likely-than-not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. Stock-Based Compensation Stock-based compensation expense is measured at the grant date based on the estimated fair value of the stock-based award and is generally expensed on a straight-line basis over the requisite service period and/or performance period of the award. Forfeitures are recognized when incurred. Stock-based compensation expense related to manufacturing employees and administrative employees is included in the "Consumables Cost of revenue, exclusive of depreciation and amortization" and "Payroll and benefits" line items, respectively, in the Consolidated Statements of Operations. Stock-based compensation expense related to non-employee directors and consultants is included in the "General and administrative" line item in the Consolidated Statements of Operations. Dividends When a sufficient amount of available earnings exists at the time of a dividend declaration, dividends are charged to Retained earnings when declared. If a sufficient amount of available earnings is not available, dividends declared are charged as a reduction to Additional paid-in capital. Earnings (Loss) Per Share Basic earnings (loss) per share is computed using the weighted-average number of shares of common stock outstanding during the reporting period. Diluted earnings per share is computed in a manner consistent with that of basic earnings per share, while considering other potentially dilutive securities. The treasury stock method is used to determine the dilutive effect of potentially dilutive securities. 52 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements Potentially dilutive securities consist of restricted stock awards ("RSAs") and contingent performance stock units ("PSUs") (collectively, "Potential dilutive shares"). Potential dilutive shares are excluded from diluted earnings (loss) per share when their effect is anti-dilutive. When there is a net loss for a period, all Potential dilutive shares are anti-dilutive and are excluded from the calculation of diluted loss per share for that period. Each PSU represents a contingent right to receive shares of the Company’s common stock, and the number of shares may range from zero to two times the number of PSUs granted on the award date depending upon the price performance of the Company's common stock as measured against a general index and a specific peer group index over requisite performance periods. The number of Potential dilutive shares related to a PSU is based on the number of shares of the Company's common stock, if any, that would be issuable at the end of the respective reporting period, assuming that the end of the reporting period is the end of the contingency period applicable to a PSU. See Note 12 for additional information related to PSUs. The following table sets forth the calculations of basic and diluted earnings (loss) per common share: Years Ended December 31, (in thousands, except per share amounts) 2023 2022 Net loss $ (12,249) $ (8,917) Basic weighted-average number of common shares outstanding 29,104 18,453 Add: dilutive effect of equity instruments — — Diluted weighted-average shares outstanding 29,104 18,453 Loss per share - basic $ (0.42) $ (0.48) Loss per share - diluted $ (0.42) $ (0.48) For the years ended December 31, 2023 and 2022, 1.7 million and 0.6 million weighted-average equity instruments, respectively, were outstanding but were not included in the computation of diluted earnings per share because their effect would have been anti-dilutive. Use of Estimates The preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States ("GAAP") requires the Company’s management to make estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. Actual results could differ from those estimates. Significant financial statement components in which the Company makes assumptions include: •business combinations, including asset acquisitions; •the carrying value of its long-lived assets; •AROs; and •income taxes, including the valuation allowance for deferred tax assets and assessment of uncertain tax positions. Risks and Uncertainties The Company is principally dependent on operations of its APT business and its cash on hand to provide liquidity over the near and long term. The Company's revenue, sales volumes, earnings and cash flows are significantly affected by prices of competing power generation sources such as natural gas and renewable energy. During periods of low natural gas prices, natural gas provides a competitive alternative to coal-fired power generation and therefore, coal consumption may be reduced, which in turn reduces the demand for the Company's products. However, during periods of higher prices for competing power generation sources, there is generally an increase in coal consumption and thus demand for the Company's products also increases. In addition, coal consumption and demand for the Company's products are affected by the demand for electricity, which is higher in the warmer and colder months of the year. As a result, the Company's operating results are subject to seasonal variations whereby its revenue and cost of revenue tend to be higher in its first and third fiscal quarters compared to its second and fourth fiscal quarters. Abnormal temperatures during the summer and winter months may significantly affect coal 53 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements consumption and impurities within various municipalities' water sources, and thus impact the demand for the Company's products. Reclassifications Certain balances have been reclassified from prior years to conform to the current year presentation. Such reclassifications had no effect on the Company’s results of operations or financial position in any of the periods presented. Segments Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by a company's chief operating decision maker ("CODM"), or a decision-making group, in deciding how to allocate resources and in assessing financial performance. As of December 31, 2023, the Company's CODM was the Company's Chief Executive Officer, and the Company concluded that it had one reportable segment. New Accounting Standards Recently Adopted Effective January 1, 2023, the Company adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). The main objective of ASU 2016-13 is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The adoption of ASU 2016-13 did not have a material impact on the Company's financial statements and disclosures. Recently Issued In December 2023, the FASB issued Accounting Standards Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ("ASU 2023-09"). ASU 2023-09 requires entities to disclose: (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) the disaggregation of income taxes paid by jurisdiction. This update also makes several other changes to the income tax disclosure requirements. For public entities, the amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024, with early adoption permitted, and is required to be applied prospectively, but retrospective application is permitted. The Company is currently evaluating the impact of ASU 2023-09 on its income tax disclosures. Note 2 - Arq Acquisition On February 1, 2023 (the "Acquisition Date"), the Company entered into a securities purchase agreement (the "Purchase Agreement") with Arq Ltd. for the Arq Acquisition in exchange for consideration (the "Purchase Consideration") totaling $31.2 million and consisting of (i) 3,814,864 shares of the Company's common stock, par value $0.001 per share (the "Common Stock"), valued at $12.4 million based on the closing price of the Common Stock on the Acquisition Date and (ii) 5,294,462 shares of the Company's Series A Convertible Preferred Stock, par value $0.001 per share (the "Series A Preferred Stock" or the "Preferred Shares"), valued at $18.8 million. The Company also incurred $8.7 million in acquisition-related costs, which have been expensed as incurred. Legacy Arq's principal location is in Corbin, Kentucky where it operates the Corbin Facility, which processes bituminous coal waste into Arq Powder and can be used as an alternative to oil or in-ground mined coal to produce a range of carbon products. With the completion of the Arq Acquisition, the Company intends to sell Arq Powder as a feedstock to produce high-quality AC for use in water and air purification markets. The Company expects to begin using Arq Powder to produce granular activated carbon products by the end of 2024. The Company accounted for the Arq Acquisition as an acquisition of a business. The total Purchase Consideration was $31.2 million and was allocated to the acquired assets and assumed liabilities of Legacy Arq based on their estimated fair values as of the Acquisition Date. The Purchase Consideration was comprised of the fair values as of the Acquisition Date of 3,814,864 shares of Common Stock, valued at $12.4 million, and 5,294,462 Preferred Shares, valued at $18.8 million. The Company also incurred $8.7 million in acquisition-related costs, which were expensed as incurred and included in the "General and administrative" and "Legal and professional fees" line items in the Statements of Operations. 54 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements The following table provides the final purchase price allocation to the assets acquired and liabilities assumed as of the date of the Arq Acquisition: (in thousands) Purchase Price Allocation Fair value of assets acquired: Cash $ 1,411 Prepaid expenses and other current assets 2,229 Restricted cash, long-term 814 Property, plant and equipment, net 39,159 Other long-term assets, net 11,717 Amount attributable to assets acquired 55,330 Fair Value of liabilities assumed: Accounts payable and accrued expenses 9,806 Current portion of long-term debt 494 Other current liabilities 103 Long-term debt, net of current portion 9,199 Other long-term liabilities 4,523 Amount attributable to liabilities assumed 24,125 Net assets acquired $ 31,205 The following represents the intangible asset identified as part of the Arq Acquisition and which is included in "Other long-term-assets, net" in the table above: (in thousands) Amount Weighted Average Useful Life (years) Developed technology $ 7,700 20 Series A Preferred Stock In connection with the issuance of the Series A Preferred Stock pursuant to the Purchase Agreement, the Company filed the Certificate of Designations of Preferred Stock for the Series A Preferred Stock (the "Certificate of Designations") with the Secretary of State of the State of Delaware. Under the Certificate of Designations, 8.9 million preferred shares were designated as Series A Preferred Stock. On June 13, 2023 (the "Conversion Date"), the Company's stockholders approved the conversion of all of the outstanding shares of Series A Preferred Stock, including the "Escrow Shares," as defined below, and the corresponding issuance of shares of Common Stock. Upon such approval, each outstanding share of Series A Preferred Stock was automatically converted into the number of shares of Common Stock described below. Each share of Series A Preferred Stock was deemed to have an original issue price of $4.00 per share (the "Original Issue Amount"). The number of shares of Common Stock issued upon conversion of each share of Series A Preferred Stock was equal to the product of (i) the sum of (A) the Original Issue Amount plus (B) an amount equal to the cumulative amount of the accrued and unpaid dividends on such share at such time divided by (ii) the Original Issue Amount, subject to adjustment. Holders of the Series A Preferred Stock were entitled to receive cumulative dividends, which accrued quarterly on the last day of each applicable quarter (whether or not declared or funds for their payment are lawfully available) and were payable quarterly, in arrears, on the earlier to occur of (a) the date any dividend is paid to holders of Common Stock with respect to such quarter and (b) 30 days after the end of each quarter (the "Series A Quarterly Dividend") at the rate per share of Series A Preferred Stock equal to the greater of (i) if the Company declared a cash dividend on the Common Stock with respect to such quarter, the amount of the cash dividend that would be received by a holder of Common Stock in which such share of Series A Preferred Stock would be convertible on the record date for such cash dividend and (ii) an annual rate (the "Rate") of 8.0% of 55 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements the Original Issue Amount compounded quarterly with respect to such quarter. On March 31, 2023, the Company declared a dividend of 68,464 Series A PIK Shares with respect to the accrued dividends on the Preferred Shares for the first quarter of 2023 (the "PIK Dividend"). The PIK Dividend was recorded at the estimated fair value of $0.2 million as of March 31, 2023 and was paid on April 21, 2023. Of the total Preferred Shares issued in the Arq Acquisition, 833,914 were held in escrow (the "Escrow Shares") based on a contingent redemption feature, (the "Contingent Redemption Feature," as defined below). The fair value of the Preferred Shares issued was determined to be $3.46 per Preferred Share on the Acquisition Date (the ("Preferred Share Price") plus the value of the Contingent Feature related to the Escrow Shares. The Escrow Shares were converted into shares of Common Stock on the Conversion Date and continue to be held in escrow (the "Escrow Common Shares"). The Escrow Common Shares are being withheld pending a determination by the IRS that no tax withholding is required on the Purchase Consideration issued to Arq Ltd. (the "Arq Ltd. Tax Liability"). The Company estimated the fair value of the potential Arq Ltd. Tax Liability at $3.3 million. In the event that the IRS determines that no withholding is required by Arq Ltd. in connection with the Purchase Consideration received by Arq Ltd., all of the Escrow Common Shares will be released and delivered to Arq Ltd. In the event that the IRS determines that any amount of withholding is required by Arq Ltd., the Company has agreed to redeem a sufficient number of Escrow Common Shares to fund the required payment to the IRS, and that number of Escrow Common Shares will be returned to the Company. The number of Escrow Common Shares to be returned to the Company is equal to the required withholding amount divided by the Original Issue Amount, not to exceed a maximum of 833,914 Escrow Common Shares, and is equal to $3.3 million based on the Original Issue Amount (the "Maximum Contingent Redemption Amount"). The fair value of the Preferred Escrow Shares was determined on the Acquisition Date and was comprised of the Maximum Contingent Redemption Amount and the fair value of the non-escrowed Preferred Shares ("Non-Preferred Escrow Shares"). The Series A Preferred Stock contained a mandatory redemption feature in the event the Preferred Shares, including future issuances of Series A Preferred Stock issued under dividend requirements, were not converted into shares of Common Stock prior to February 1, 2028. The Company concluded that both the Escrow Shares and the Non Escrow Shares did not meet the definition of mandatorily redeemable financial instruments as there was a substantive conversion feature, and were therefore not classified as liabilities. As both the Escrow Shares and Non Escrow Shares represented financial instruments that were redeemable for cash, SEC guidance mandates that preferred securities which are redeemable upon the occurrence of an event that is not solely within the control of the issuer be classified outside of permanent equity as "temporary equity." Accordingly, the Company classified and reported the Series A Preferred Stock as temporary equity and in the Consolidated Balance Sheet as of as of the Acquisition Date. On the Conversion Date, all shares of Series A Preferred Stock were converted into 5,362,926 shares of Common Stock, and the Company reclassified all of the Series A Preferred Stock to Common Stock as of June 30, 2023. PIPE Investment On February 1, 2023 and pursuant to the Arq Acquisition, the Company entered into Subscription Agreements with certain persons (the "Subscribers"), which included existing shareholders of Arq Ltd., three of which were appointed to the Company's Board of Directors (the "Board"), pursuant to which the Subscribers subscribed for and purchased 3,842,315 shares of Common Stock for an aggregate purchase price of $15.4 million and at a price per share of $4.00 (such transaction, the "PIPE Investment"). 56 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements Unaudited Pro Forma Financial Information The following represents the pro forma effects of the Arq Acquisition as if it had occurred on January 1, 2022. The pro forma net loss for each of the two years presented has been calculated after applying the Company’s accounting policies in effect for those years. In addition, pro forma net loss includes: (1) for the years ended December 31, 2023 and 2022, increases in depreciation and amortization resulting from fair value adjustments to Property, plant, equipment of $0.2 million and $0.1 million, respectively; (2) for the years ended December 31, 2023 and 2022, increases in amortization resulting from fair value adjustments to Intangibles of $0.1 million and $0.4 million, respectively; (3) for the year ended December 31, 2023 and 2022, increases to interest expense for: (a) the issuance of the CFG Loan (as defined below) including stated interest and the amortization of the CFG Loan's discount and issuance costs and (b) amortization of debt discount related to a fair value adjustment to the assumed CTB Loan (as defined below) of Arq of $0.2 million and $2.0 million, respectively; (4) the removal of $1.9 million of Payroll and benefits for compensation expense payable to certain Arq employees triggered by change in control provisions in employment agreements, as well as in employee severance agreements, for the year ended December 31, 2023 but included as additional Payroll and benefits expense for the year ended December 31, 2022; (5) for the years ended December 31, 2023 and 2022, decreases to general and administrative expenses resulting from fair value adjustments to operating leases acquired of $0.1 million and $0.5 million, respectively, and (6) for the year ended December 31, 2022, the addition of $2.4 million of transaction costs incurred for the period from January 1, 2023 through the Arq Acquisition Date, together with the income tax effects on (1) through (6). Since Arq had no revenue for the years ended December 31, 2023 or 2022, pro forma revenue is the same as the Company's reported revenue for those years. Years ended December 31, (in thousands) 2023 2022 Revenue $ 99,183 $ 102,987 Net loss $ (11,119) $ (75,788) Other The amounts of year to date revenue and net loss for Arq for the period from the Acquisition Date to December 31, 2023 are as follows: Year ended December 31, (in thousands) 2023 Revenue $ — Net loss $ (11,660) Note 3 - Inventories, net The following table summarizes the Company's inventories as of December 31, 2023 and 2022: As of December 31, (in thousands) 2023 2022 Product inventory $ 9,524 $ 9,479 Raw material inventory 10,169 8,349 $ 19,693 $ 17,828 57 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements Note 4 - Property, Plant and Equipment The cost basis and accumulated depreciation of property, plant and equipment at December 31, 2023 and 2022 are summarized in the table below: As of December 31, (in thousands) Life in Years 2023 2022 Land and land improvements 5+1 $ 1,225 $ 1,225 Plant and operating equipment 3-29 81,266 33,180 Furniture and fixtures 1-19 1,765 1,709 Machinery and equipment 3-10 2,478 2,116 Leasehold improvements 12 2,149 2,149 Construction in progress 25,059 6,373 113,942 46,752 Less accumulated depreciation (19,293) (11,897) Total property, plant and equipment, net $ 94,649 $ 34,855 1 Land Improvements have a useful life between 5 and 31 years. Included in plant and operating equipment as of December 31, 2023 and 2022 is mining equipment financed under various lease facilities, and obligations due under these facilities are included in long-term debt in the Consolidated Balance Sheets. The total amount recorded for ROU assets as of December 31, 2023 and 2022 related to finance lease obligations was $1.7 million and $2.6 million, respectively, net of accumulated depreciation of $2.7 million and $2.0 million. Depreciation expense for the years ended December 31, 2023 and 2022 was $8.5 million and $4.9 million, respectively. Note 5 - Revenue For the years ended December 31, 2023 and 2022, all material performance obligations related to revenue recognized were satisfied at a point in time. For each of the years ended December 31, 2023 and 2022, approximately 8%, respectively, of Consumables revenue was generated in Canada, and all other revenue was generated in the U.S. In accordance with its revenue recognition policy for MQ Contracts, in December 2023, the Company exercised its right under certain MQ Contracts and recognized $4.7 million of consumables revenue and recorded an unbilled receivable. Trade receivables Trade receivables represent an unconditional right to consideration in exchange for goods or services transferred to a customer. The Company invoices its customers in accordance with the terms of the contract. Credit terms are generally net 30 - 45 days from the date of invoice. The timing between the satisfaction of performance obligations and when payment is due from the customer is generally not significant. Contract assets Contract assets are comprised of unbilled receivables from customers and are included in Receivables, net in the Consolidated Balance Sheets. Unbilled receivables represent a conditional right to consideration in exchange for goods or services transferred to a customer. The following table shows the components of the Company's Receivables, net: As of December 31, (in thousands) 2023 2022 Trade receivables, net $ 11,289 $ 13,789 Unbilled receivables 4,862 — Other 41 75 Receivables, net $ 16,192 $ 13,864 58 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements Contract liabilities Contract liabilities are comprised of deferred revenue, which represents an obligation to transfer goods or services to a customer for which the Company has received consideration from the customer and, if deliverable within one year or less, is included in "Other current liabilities" in the Consolidated Balance Sheets and, if deliverable outside of one year, is included in "Other long-term liabilities" in the Consolidated Balance Sheets.

The Company received net cash proceeds of $8.5 million after deducting the OID and debt issuance costs of $1.3 million. The CFG Loan Agreement also required the issuance of a warrant (the "Warrant") to CFG to purchase 325,457 shares of Common Stock (the "Warrant Shares"), which represented 1% of the post-Arq Acquisition and PIPE Investment (as defined below) fully diluted share capital (as defined in the CFG Loan Agreement), at an exercise price of $0.01 per share. The Warrant has a term of 7 years and contains a cashless exercise provision. The Company allocated the cash proceeds of the CFG Loan Agreement to both the CFG Loan and the Warrant based on their relative fair values. The amount allocated to the Warrant was recorded as a debt discount and is amortized to interest expense over the term of the CFG Loan. The standalone fair value of the CFG Loan was based on a comparison of borrowings and associated credit ratings consistent with those of the Company. The Warrant is exercisable for $0.01 per share, and the fair value is deemed to be equal to the fair value of the underlying shares. Accordingly, the fair value of the Warrant was determined as the number of shares issuable from the exercise of the Warrant (based on 1.0% of post-transaction fully diluted share capital, as defined in the Purchase Agreement) multiplied by the closing share price of the Company's common stock on the Acquisition Date. The CFG Loan matures on February 1, 2027 and bears interest at a rate equal to either (a) Adjusted Term SOFR (subject to a 1.00% floor and a cap of 2.00%) plus a margin of 9.00% paid in cash and 5.00% paid in kind or (b) Base Rate plus a margin of 8.00% paid in cash and 5.00% paid in kind, which interest on the CFG Loan in each case shall be payable (or capitalized, in the case of in kind interest) quarterly in arrears. The Company may prepay the CFG Loan at any time subject to the following prepayment premium: (i) prior to the twelve month anniversary of the Closing Date, the Make-Whole Amount (as defined below), (ii) thereafter but prior to the thirty-six month anniversary of the Closing Date, 2.00% of the outstanding principal amount of the CFG Loan being repaid or prepaid or (iii) thereafter until the maturity date, 1.00% of the outstanding principal amount of the CFG Loan being repaid or prepaid. The "Make-Whole Amount," with respect to any repayment or prepayment, is (i) an amount equal to all required interest payable (except for currently accrued and unpaid interest) on the aggregate principal amount of the CFG Loan subject to such 59 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements prepayment or repayment from the date of such prepayment or repayment through but excluding the date that is the first anniversary of the Closing Date calculated using an interest rate equal to (x) Adjusted Term SOFR for an interest period of one month in effect on the third U.S. Government Securities Business Day prior to such prepayment or repayment plus (y) 14.00% per annum and assuming all interest was paid in cash, plus (ii) a prepayment premium of 2.00% on the aggregate principal amount of the CFG Loan subject to such prepayment or repayment. The CFG Loan is secured by substantially all of the assets of the Company and its subsidiaries (including those acquired in the Arq Acquisition, but excluding those pledged as collateral (the "Arq Loan Assets") under the "CTB Loan," as defined and described below), subject to customary exceptions. The CFG Loan Agreement includes, among others, the following covenants: (1) beginning with the first fiscal quarter after March 31, 2023 and as of the end of each fiscal quarter thereafter, the Company must maintain a minimum unrestricted cash balance of $5.0 million; (2) (x) as of December 31, 2023, for the fiscal year then ended, the Company must have a minimum annual revenue, on a consolidated basis, of $70.0 million, (y) as of December 31, 2024, for the fiscal year then ended, the Company must have a minimum annual revenue, on a consolidated basis, of $85.0 million and (z) for any fiscal year thereafter, the Company must have a minimum annual revenue, on a consolidated basis, of $100.0 million; (3) (x) as of December 31, 2024, for the fiscal year then ended, the Company must have a minimum Consolidated EBITDA of $3.0 million and (y) for any fiscal year thereafter, the Company must have a minimum Consolidated EBITDA of $16.0 million; and (4) beginning after the fiscal quarter ending September 30, 2023, during an LTV Trigger Period, Arq must not exceed a loan to value ratio of 0.40:1.00 (based on the consolidated total assets of the Company and its subsidiaries, but excluding the Arq Loan Assets). CTB Term Loan As consideration in the Arq Acquisition, the Company assumed a term loan (the "CTB Loan") held by certain Arq subsidiaries, as borrowers, as set out in the Arq Loan (the "Arq Subsidiaries") held by Community Trust Bank ("CTB") in the principal amount of $10.0 million. The Company recorded the CTB Loan on the Acquisition Date at its estimated fair value of $9.7 million, with the difference of $0.3 million between the estimated fair value and the principal amount recorded as a debt discount and recognized as interest expense over the term of the CTB Loan. The CTB Loan was originally entered into on January 27, 2021 and is comprised of two promissory notes (the "Notes"): (1) "Note A" in the principal amount of $8.0 million, which is guaranteed by the U.S. Department of Agriculture; and (2) "Note B" in the principal amount of $2.0 million. The Notes mature on January 27, 2036 and bear interest at 6.0% per annum through January 2026 and at the prime rate plus 2.75% thereafter. Beginning January 27, 2023 and for the balance of the term of the CTB Loan, the Arq Subsidiaries are required to make combined interest and principal payments monthly in the fixed amount of $0.1 million. Interest is computed and payable on the outstanding principal as of the end of the prior month and the balance of the fixed monthly payment amount is applied to the outstanding principal.

As consideration for CTB entering into the CTB Loan Modification Agreement, the Borrowers agreed to pay a fee of $50,000 plus additional fees incurred by CTB and were required to deposit an additional $0.7 million into a deposit account (the "Interest Reserve Account" as defined in the CTB Loan Agreement), where the Interest Reserve Account is held as collateral by CTB. The Borrowers may withdraw funds from the Interest Reserve Account beginning one year from the Amendment Date, subject to restrictions as stated in the CTB Loan Modification Agreement. The CTB Loan Modification Agreement clarified and modified certain terms under the CTB Loan Agreement. The principal clarifications and modifications are as follows: •The Borrowers are not entitled to any further disbursements of proceeds under those promissory notes described in the CTB Loan Modification Agreement; •CTB agreed to waive certain financial delivery requirements for fiscal years 2021 and 2022; 60 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements •CTB agreed to waive certain required financial covenants required as of December 31, 2022 and certain required financial covenants as of December 31, 2023; •The Borrowers were required to establish their operating bank accounts with CTB no later than September 30, 2023; and •CTB is authorized to amend and/or amend and restate its then-current security instruments to include additional collateral represented by the Borrowers' acquisition of any equipment or other fixed and/or operating assets in which CTB does not then hold a lien or security interest. The CTB Loan is secured by substantially all assets of the Borrowers and includes among others, the following covenants with respect to the Borrowers, which are tested annually (Capitalized terms are defined in the CTB Loan Agreement): (a) Total Indebtedness to Net Worth greater than 4 to 1; (b) Balance Sheet Equity greater than or equal to 20% of the book value of all assets of the Borrowers; (c) (i) net income plus interest, taxes, depreciation and amortization divided by (ii) interest expense plus current maturities on long-term debt greater than or equal to 1.25 to 1.

On July 14, 2023, the Board appointed Mr. Robert Rasmus to the positions of President and Chief Executive Officer effective July 17, 2023. On July 17, 2023, the Company entered into a Subscription Agreement (the "Subscription Agreement") with Mr. Rasmus and entities controlled by Mr. Rasmus, in connection with his appointment as the Company’s President and Chief Executive Officer.

As of December 31, 2023, the Company had $7.0 million remaining under the Stock Repurchase Program. Note 12 - Stock-Based Compensation On May 16, 2022, the Company's stockholders approved the 2022 Omnibus Incentive Plan (the "2022 Plan"), which permits grants of awards to employees, directors and consultants. Awards may be in the form of options (both nonqualified stock options and incentive stock options), stock appreciation rights, restricted stock, restricted stock units, performance share units, and other stock-based awards and cash-based awards as described under the 2022 Plan. As of December 31, 2023, the Company has 190,281 shares of its common stock authorized for issuance under the 2022 Plan. On June 20, 2017, the Company's stockholders approved the 2017 Omnibus Incentive Plan (the "2017 Plan"), which permits grants of awards to employees, directors and non-employees. Awards may be in the form of shares, rights to purchase restricted stock, bonuses of restricted stock, or other rights or benefits as described under the 2017 Plan. As of December 31, 2023, the Company has zero shares of its common stock authorized for issuance under the 2017 Plan. Expense RSAs - Restricted Stock Awards ("RSA's") are typically granted with vesting terms of three years. The fair value of RSAs is determined based on the closing price of the Company’s common stock on the authorization date of the grant multiplied by the number of shares subject to the stock award. Compensation expense for RSAs is generally recognized over the vesting term on a straight-line basis. PSUs - Performance share units ("PSU's") generally vest over three years and are based on the grantee’s continuous service with the Company, performance measures or a combination of both. Each PSU represents a contingent right to receive shares of the Company’s common stock if the Company meets certain performance measures over the requisite period. Compensation expense is recognized for PSU awards on a straight-line basis over the vesting period based on the estimated fair value at the date of grant using a Monte Carlo simulation model. The Company's Monte Carlo simulation models include the following assumptions: •Risk-free interest rate - The risk-free interest rate for PSUs granted during the period was determined by using a zero-coupon, U.S. Treasury rate for the periods that coincided with the expected terms listed above. •Dividends - As the PSUs granted receive dividend equivalent units, no discount was applied for any dividends declared. •Expected volatility - To calculate expected volatility, the historical volatility of the Company's common stock was used. •Performance period - The Company’s performance period is based on the vesting term of the Company’s PSU awards. Stock Options Stock options vest over three years and have a contractual limit of ten years from the date of grant to exercise. The fair value of stock options granted is determined on the date of grant using the Black-Scholes option pricing model, and the related expense is recognized on a straight-line basis over the entire vesting period. The determination of the grant date fair value of stock options issued is affected by a number of variables, including the fair value of the Company’s common stock, the expected common stock price volatility over the expected term of the stock option, the expected term of the stock option, risk-free interest rates, and the expected dividend yield of the Company’s common stock. The Company's Black Scholes option pricing models include the following assumptions: •Risk-free interest rate - The risk-free interest rate for stock options granted during the period was determined by using a zero-coupon U.S. Treasury rate for the periods that coincided with the expected term of the options. •Dividend yield - An expected dividend yield of zero was included in the calculations, as the Company does not currently pay nor does it anticipate paying dividends on its common stock as of the grant date of the stock options. •Expected volatility - To calculate expected volatility, the historical volatility of the Company's common stock was used. 68 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements •Expected term - The Company’s expected term of stock options was calculated using a simplified method whereby the midpoint between the vesting date and the end of the contractual term is utilized to compute the expected term, as the Company does not have sufficient historical data for options with similar vesting and contractual terms. The following table indicates the weighted average assumptions that were used related to the awards granted during the year ended December 31, 2023: Year ended December 31, 2023 Stock options granted: 1,000,000 Risk-free interest rate 4 % Dividend yield — % Volatility 62 % Expected term (in years) 6 The Company recorded the following compensation expense related to the Stock Plans: Years Ended December 31, (in thousands) 2023 2022 RSA expense $ 1,887 $ 1,679 PSU expense 650 302 Stock option expense 111 — Total stock-based compensation expense $ 2,648 $ 1,981 Stock-based compensation expense related to manufacturing employees and administrative employees is included in the "Consumables cost of revenue, excluding depreciation and amortization" and "Payroll and benefits" line items in the Consolidated Statements of Operations. Stock-based compensation expense related to non-employee directors is included in the "General and administrative" line item in the Consolidated Statements of Operations.

The total grant-date fair value of RSAs vested for the years ended December 31, 2023 and 2022 was $2.0 million and $1.7 million, respectively.

PSUs PSUs outstanding remain unvested until either the requisite performance condition of the grant is met, or the third anniversary of their issuance date, at which time the actual number of vested shares will be determined based on the actual price performances of the Company’s common stock relative to a broad stock index and a peer group performance index.

These temporary differences result in taxable or deductible amounts in future years. Details of the Company’s deferred tax assets and liabilities are summarized as follows: As of December 31, (in thousands) 2023 2022 Deferred tax assets Tax credits $ 86,125 $ 86,125 Net operating loss carryforwards 17,018 2,892 Intangible assets 1,061 2,638 Employee related liabilities 1,047 1,968 Operating lease obligations 2,506 1,828 ARO, net of reimbursements 1,428 1,448 Research and development capitalization 1,227 739 Other investments 515 518 Equity method investments — 325 Inventory 612 315 Interest limitations 121 77 Other 647 429 Total deferred tax assets 112,307 99,302 Less valuation allowance (98,836) (88,293) Deferred tax assets 13,471 11,009 Less: Deferred tax liabilities Property and equipment and other (9,230) (7,702) Right of use operating lease assets (2,454) (1,800) Upfront customer consideration (1,383) (1,507) Equity method investments (404) — Total deferred tax liabilities (13,471) (11,009) Net deferred tax assets $ — $ — Accounting for income taxes requires that companies assess whether a valuation allowance should be recorded against a deferred tax asset based on an assessment of the amount of the deferred tax asset that is "more likely than not" to be 72 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements realized. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that is more likely than not to be realized. The Company assesses a valuation allowance recorded against deferred tax assets at each reporting date. The determination of whether a valuation allowance is appropriate requires the evaluation of positive and negative evidence that can be objectively verified. Consideration must be given to all sources of taxable income available to realize a deferred tax asset, including, as applicable, the future reversal of existing temporary differences, future taxable income forecasts exclusive of the reversal of temporary differences and carryforwards, taxable income in carryback years and tax planning strategies. In estimating taxes, the Company assesses the relative merits and risks of the appropriate tax treatment of transactions taking into account statutory, judicial and regulatory guidance. As of December 31, 2023, the Company concluded it is more likely than not the Company will not generate sufficient taxable income within the applicable net operating loss and tax credit carry-forward periods to realize any of its net deferred tax assets. For the year ended December 31, 2023, the Company increased a valuation allowance from December 31, 2022 by $10.5 million and as of December 31, 2023, has a valuation allowance equal to 100% of its net deferred tax assets. In reaching this conclusion, the Company primarily considered forecasts of future taxable losses. The following table presents the approximate amount of federal and state net operating loss carryforwards and federal tax credit carryforwards available to reduce future taxable income, along with the respective range of years that the net operating loss and tax credit carryforwards would expire if not utilized: As of December 31, (in thousands) 2023 Beginning expiration year Ending expiration year Federal net operating loss carryforwards (1) $ 10,177 2035 Indefinite Foreign net operation loss carryforwards $ 3,629 Indefinite Indefinite State and other net operating loss carryforwards $ 3,211 2025 Indefinite Federal tax credit carryforwards $ 86,125 2032 2041 (1) Approximately $8.8 million of the federal net operating loss carryforwards were acquired in the Arq Acquisition, of which $6.2 million have expiration dates beginning in 2035. The following table sets forth a reconciliation of the beginning and ending unrecognized tax positions on a gross basis for the years ended December 31, 2023 and 2022: Years Ended December 31, (in thousands) 2023 2022 Balance as of January 1 $ 54 $ 54 Lapse of applicable statute of limitations — — Balance as of December 31 $ 54 $ 54 For the years ended December 31, 2023 and 2022, the Company did not record any adjustments or recognize interest expense for uncertain tax positions. Interest and penalties related to uncertain tax positions are accrued and included in the "Interest expense" line item in the Consolidated Statements of Operations. Additional information related to the components of "Interest expense" is included in Note 10. The Company files income tax returns in the U.S., various states and the United Kingdom. The Company is no longer subject to U.S. federal examinations by tax authorities for years before 2020. The Company is generally no longer subject to state examinations by tax authorities for years before 2016. U.S. federal income tax rules, and Sections 382 of the Internal Revenue Code in particular, could substantially limit the use of Section 45 tax credits and other tax assets if the Company experiences an "ownership change" (as defined in the Internal Revenue Code). In general, an ownership change occurs if the aggregate stock ownership of certain stockholders (generally 5% stockholders, applying certain look-through rules) increases by more than 50 percentage points over such stockholders' lowest percentage ownership during the testing period (generally three years). 73 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements An entity that experiences an ownership change generally will be subject to an annual limitation on its pre-ownership change tax loss and credit carryforwards equal to the equity value of the entity immediately before the ownership change, multiplied by the long-term, tax-exempt rate posted monthly by the Internal Revenue Service (subject to certain adjustments). The annual limitation would be increased each year to the extent that there is an unused limitation in a prior year. In connection with the Arq Acquisition and PIPE Investment, we issued additional shares of our common stock. We performed an IRC Section 382 analysis as of the Acquisition Date and determined that we had not experienced an ownership change as of that date. The Company acquired certain tax assets (the "Legacy Arq Tax Assets") in the Arq Acquisition, totaling approximately $12.5 million. The Legacy Arq Tax Assets are comprised of net operating loss carryforwards, of which $8.8 million were in the U.S. Prior to the Acquisition Date, Legacy Arq completed numerous equity offerings that resulted in ownership changes. We have not completed a formal IRC Section 382 analysis of Legacy Arq equity changes from its inception through the Acquisition Date, however, the Company believes that one or more "ownership changes" occurred during this time period as defined under Sections 382 and 383 and that a portion or all the Legacy Arq Tax Assets may subject to an annual limitation. On May 5, 2017, the Board approved the declaration of a dividend of rights to purchase Series B Junior Participating Preferred Stock for each outstanding share of common stock as part of a tax asset protection plan (the "TAPP"), which is designed to protect the Company’s ability to utilize its net operating losses and tax credits. The TAPP is intended to act as a deterrent to any person acquiring beneficial ownership of 4.99% or more of the Company’s outstanding common stock. During the years 2018-2023, we executed amendments to the TAPP (the "TAPP Amendments"), which amended the definition of "Final Expiration Date" under the TAPP to extend the duration of the TAPP and makes associated changes in connection therewith. The most recent TAPP Amendment was approved at our 2023 annual meeting of stockholders and extended the Final Expiration Date to the close of business on December 31, 2024. Note 14 - Major Customers Revenue from external customers who represent 10% or more of the Company’s revenue for the years ended December 31, 2023 and 2022 were as follows: Years ended December 31, Customer Revenue Type 2023 2022 A Consumables 19% 18% B Consumables 9% 11% Note 15 - Related Party Transactions Consumables Cost of Revenue For the year ended December 31, 2023, the Company recognized $0.7 million of Tinuum Group Royalty expense, which is included in the "Consumables cost of revenue, exclusive of depreciation and amortization" line item in the Consolidated Statement of Operations. Tinuum Group Obligation As of December 31, 2023 and 2022, the Company had an outstanding liability of $1.7 million related to its contractual amount due under the Tinuum Group Obligation, which is included in the "Other current liabilities" line item in the Consolidated Balance Sheet. Refer to Note 8 for further discussion. Note 16 - Defined Contribution Savings Plans The Company sponsors a qualified defined contribution savings plan (the "401(k) Plan") that allows participation by eligible employees who may defer a portion of their gross pay. The Company makes contributions to the 401(k) Plan based on percentages of an employee's eligible compensation as specified in the 401(k) Plan, and such employer contributions are in the form of cash. 74 -------------------------------------------------------------------------------- Arq, Inc. and Subsidiaries Notes to Consolidated Financial Statements The following table presents the amount of the Company's contributions made to the 401(k) Plans: Years Ended December 31, (in thousands) 2023 2022 401(k) Plans employer contributions $ 613 $ 552 75 -------------------------------------------------------------------------------- Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None. Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures As required by Rule 13a­15(b) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), we have evaluated, under the supervision of and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a­15(e) and 15d­15(e) under the Exchange Act) as of the end of the period covered by this annual report. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Based upon this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2023. Management’s Report on Internal Control over Financial Reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. The Company's internal control over financial reporting includes those policies and procedures that: 1.Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; 2.Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of our management and directors; and 3.Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on our financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Under the supervision of, and with the participation of our management, including the principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework and criteria established in Internal Control-Integrated Framework in 2013, issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2023. We acquired Legacy Arq during the first quarter of 2023 (refer to Item 8. Note 2 of this Report). As permitted by Securities and Exchange Commission Staff interpretive guidance for newly acquired businesses, management excluded Legacy Arq from its evaluation of internal control over financial reporting as of December 31, 2023. We are in the process of documenting and testing Legacy Arq's internal controls over financial reporting. We will incorporate Legacy Arq into our annual report on internal control over financial reporting for our year ending December 31, 2024. As of December 31, 2023, Legacy Arq net assets totaled $40.5 million. Legacy Arq contributed $11.7 million of net loss in our Consolidated Statements of Operations for the year ended December 31, 2023. Changes in Internal Control Over Financial Reporting There has been no change in our internal control over financial reporting (as defined in Rules 13a­15(f) and 15d­15(f) under the Exchange Act) during the fourth quarter of 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 76 -------------------------------------------------------------------------------- Item 9B.

Spencer Wells, Director Robert Rasmus, Director Date: March 12, 2024 Date: March 12, 2024 83 EX-4.10 2 exhibit410descriptionofreg.htm EX-4.10 Exhibit 4.10 DESCRIPTION OF REGISTRANT SECURITIES The following descriptions of our capital stock and certain provisions of our second amended and restated certificate of incorporation, our bylaws, as amended, and our Tax Asset Protection Plan (as defined below), as amended, are summaries and are qualified by reference to our second amended and restated certificate of incorporation and bylaws. Our authorized capital stock consists of 150,000,000 shares of capital stock, par value $0.001 per share, of which: •100,000,000 shares are designated as common stock; and •50,000,000 shares are designated as preferred stock. Common Stock As of December 31, 2023, we had 33,172,938 shares of common stock issued and outstanding. Voting Rights Each holder of common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders. Our second amended and restated certificate of incorporation does not provide for cumulative voting rights. Our bylaws provide that the election of any director and proposals designated by the directors will be decided by a plurality of the votes cast at a meeting of the stockholders by the holders of stock entitled to vote in the election. With respect to matters other than the election of directors and proposals designated by the director as being subject to a plurality vote, such matters shall be approved if the votes cast favoring the matter exceed the votes cast opposing the mater at a meeting of the stockholders by the holders of stock entitled to vote. The holders of one-third of the voting power of the outstanding shares of Common Stock entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum for the transaction of business at all meetings of the stockholders. Dividends Our bylaws provide that, subject to applicable law, dividends upon shares of our capital stock may be declared by the board of directors and may be paid in cash, in property or in shares of our capital stock, unless otherwise provided by applicable law. Liquidation In the event of our liquidation, dissolution or winding up, whether voluntary or involuntary, after payment or provision for payment of our debts and other liabilities and the preferential amounts to which the holders of any outstanding shares of preferred stock are entitled to receive on dissolution, liquidation, or winding up, the holders of the common stock are entitled to share on a pro rata basis in our remaining assets. Rights and Preferences Holders of our common stock have no preemptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions applicable to our common stock. The rights, preferences and privileges of the holders of our common stock are subject to and may 1 -------------------------------------------------------------------------------- be adversely affected by the rights of the holders of shares of any series of our preferred stock that we may designate in the future. Fully Paid and Nonassessable All of our outstanding shares of common stock are fully paid and nonassessable. Preferred Stock As of December 29, 2023, there were no shares of preferred stock outstanding. We previously designated 8,900,000 shares as Series A Convertible Preferred, and issued 5,294,462 shares. All were subsequently converted in Common Stock. We also have 50,000 shares of Series B Junior Participating Preferred Stock, par value $0.001 per share, authorized and reserved for issuance upon the exercise of the Rights (as defined below) under our Tax Asset Protection Plan, as described below. Our second amended and restated certificate of incorporation provides that our board of directors has the authority, subject to limitations prescribed by Delaware law, to issue preferred stock in one or more series, to establish from time to time the number of shares to be included in each series, and to fix the designation, powers, preferences, and rights of the shares of each series and any of its qualifications, limitations, or restrictions, in each case without further vote or action by our stockholders. Our board of directors also has the authority to increase or decrease the number of shares of any series of preferred stock, but not below the number of shares of that series then outstanding, without any further vote or action by our stockholders. Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring, or preventing a change in control of our company and might adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock. We have no current plan to issue any shares of preferred stock. Anti-Takeover Provisions Certain provisions of Delaware law, and our amended and restated certificate of incorporation and amended and restated bylaws, which are summarized below, may have the effect of delaying, deferring, or discouraging another person from acquiring control of us. They are also designed, in part, to encourage persons seeking to acquire control of us to negotiate first with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us because negotiation of these proposals could result in an improvement of their terms. Delaware Takeover Statute and Certain Business Combinations We have elected not to be governed by the provisions of Section 203 of the DGCL. In general, Section 203 prohibits a public Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, subject to certain exceptions. Our second amended and restated certificate of incorporation includes provisions requiring 2 -------------------------------------------------------------------------------- certain business combinations to be approved by the affirmative vote of the holders of at least a majority of the voting power of the then outstanding voting stock, voting together as a single class, including the affirmative vote of the holders of at least a majority of the voting power of the then outstanding voting stock not owned directly or indirectly by any interested stockholder (i.e. a person who owns 10% or more of our outstanding voting stock) or any affiliate of an interested stockholder. Subject to some exceptions set forth in the second amended and restated certificate of incorporation, such affirmative vote shall be required notwithstanding the fact that no vote may be required, or that a lesser percentage may be permitted, by applicable law or in any agreement with any national securities exchange or otherwise. Removal of Directors; Vacancies. The DGCL provides that a director may be removed, with or without cause, by the holders of a majority of the shares entitled to vote at an election of directors. Our bylaws provide that newly created directorships resulting from an increase in the authorized number of directors and any vacancies occurring in the board of directors, may be filled by the affirmative votes of a majority of the remaining members of the board of directors, although less than a quorum. A director so elected shall hold office until the earlier of the expiration of the term of office of the director whom he or she has replaced, a successor is duly elected and qualified or the earlier of such director’s death, resignation or removal. No Cumulative Voting. The DGCL provides that stockholders are not entitled to cumulate votes in the election of directors unless a corporation’s certificate of incorporation provides otherwise. Our second amended and restated certificate of incorporation does not provide for cumulative voting. Stockholder Meetings; Requirements for Advance Notice. Our bylaws provide that special meetings of stockholders for any purpose or purposes may be called pursuant to a resolution approved by the board of directors or by the holders of shares entitled to cast not less than 20% of the votes at the meeting, and shall be held at such place, on such date, and at such time as the board of directors shall fix. Our bylaws provide that notice of the place, if any, date, hour, the record date for determining the stockholders entitled to vote at the meeting (if such date is different from the record date for stockholders entitled to notice of the meeting) and means of remote communication, if any, of every meeting of stockholders shall be given not less than ten days nor more than 60 days before such meeting (unless a different time is specified by law) to every stockholder entitled to vote at the meeting as of the record date for determining the stockholders entitled to notice of the meeting and that notices of special meetings shall also specify the purpose or purposes for which the meeting has been called. Authorized but Unissued Shares. Our authorized but unissued shares of common stock and preferred stock will be available for future issuances without stockholder approval, except as required by the listing standards of Nasdaq, and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred stock could render more difficult or discourage an attempt to obtain control of the company by means of a proxy contest, tender offer, merger or otherwise. 3 -------------------------------------------------------------------------------- Tax Asset Protection Plan. On May 5, 2017, our board of directors approved the Tax Asset Protection Plan (the "Original TAPP", and as amended up to the date of this disclosure, the “TAPP”) and declared a dividend of one preferred share purchase right (each, a "Right") for each outstanding share of our common stock. During the years 2018-2023, we executed amendments to the TAPP (the "TAPP Amendments"), which extend the duration of the TAPP to a later “Final Expiration Date” and make associated changes in connection therewith. The most recent TAPP Amendment was approved at our 2023 annual meeting of stockholders and extended the Final Expiration Date to the close of business on December 31, 2024. Subject to the terms, provisions and conditions of the TAPP, if the Rights become exercisable, each Right would initially represent the right to purchase one ten-thousandth of a shares of our Series B Junior Participating Preferred Stock, par value $0.001 per share, for a purchase price of $50.00, subject to certain adjustments. The description and terms of the Rights were set forth in the Original TAPP, dated as of May 5, 2017, by and between us and Computershare Trust Company, N.A., as Rights Agent, as amended. The TAPP was adopted in an effort to protect stockholder value by attempting to diminish the risk that our ability to use certain general business credits carryforwards to reduce potential future federal income tax obligations may become substantially limited if we experience an "ownership change," as defined by Section 382 of the Internal Revenue Code. The TAPP is intended to act as a deterrent to any person acquiring beneficial ownership of 4.99% or more of our outstanding common stock without the approval of the board of directors. Stockholders who beneficially owned 4.99% or more of our outstanding common stock upon execution of the TAPP will not trigger the TAPP so long as they do not acquire beneficial ownership of additional shares of our common stock. The board of directors may, in its sole discretion, also exempt any person from triggering the TAPP. Limitations of Liability and Indemnification Our bylaws provide that the Company is only authorized to provide indemnification to present or former directors or officers after a determination to do so (i) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (ii) by a committee of such directors designated by a majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by the stockholders. If a determination to provide indemnification is made, then to the fullest extent permitted by applicable law, any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason of the fact that such person is or was a director or officer of the corporation, or is or was a director or officer of the corporation serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful, 4 -------------------------------------------------------------------------------- except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper. Our second amended and restated certificate of incorporation and amended and restated bylaws further provide that to the fullest extent permitted by law, a director shall not be personally liable to the Company or to our stockholders for monetary damages for any breach of fiduciary duty as a director. No amendment to, modification of or repeal of this provision shall apply to or have any effect on the liability or alleged liability of any director for or with respect to any acts or omissions of such by a director occurring prior to such amendment. The limitation of liability and indemnification provisions in our organizational documents may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against directors and officers, even though an action, if successful, might benefit us and our stockholders. Moreover, a stockholder’s investment may be harmed to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable. There is no pending litigation or proceeding naming any of our directors or officers as to which indemnification is being sought, nor are we aware of any pending or threatened litigation that may result in claims for indemnification by any director or officer. Transfer Agent and Registrar The transfer agent and registrar for our common stock is Computershare Trust Company, N.A. Listing Our common stock is listed on Nasdaq under the symbol "ARQ." 5 EX-10.3 3 exhibit103formof2022omnibu.htm EX-10.3 Exhibit 10.3 ADVANCED EMISSIONS SOLUTIONS, INC. 2022 OMNIBUS INCENTIVE PLAN RESTRICTED STOCK AWARD AGREEMENT 1.Award of Shares. ADVANCED EMISSIONS SOLUTIONS, INC., a Delaware corporation (the “Company”), hereby awards to the Grantee (the “Grantee”) named in the Notice of Restricted Stock Award (the “Notice”), the Total Number of Shares Awarded set forth in the Notice (the “Shares”), subject to the Notice, this Restricted Stock Award Agreement (the “Agreement”) and the terms and provisions of the Company’s 2022 Omnibus Incentive Plan (as amended from time to time, the “Plan”), and any written employment, retention or severance agreement the Grantee has with the Company or its Affiliate addressing the award and vesting of Company common stock (the “Employment Agreement”), all of which are incorporated herein by reference. Unless otherwise defined herein, capitalized terms used herein shall have the meanings set forth in the Plan. All Shares awarded hereunder will be deemed issued to the Grantee as fully paid and non-assessable Shares and the Grantee will have the right to vote the Shares at meetings of the Company’s stockholders. The Company shall pay any applicable stock transfer taxes imposed upon the issuance of the Shares to the Grantee hereunder. 2.Consideration. The grant of the Shares is made in consideration of the services to be rendered by the Grantee to the Company or its Affiliate. 3.Transfer Restrictions. The Shares awarded to the Grantee hereunder may not be sold, transferred by gift, pledged, hypothecated, or otherwise transferred or disposed of by the Grantee prior to the date when the Shares become vested pursuant to the Vesting Schedule set forth in the Notice. Any attempt to transfer Restricted Stock in violation of this Section 3 will be null and void and, if any such attempt is made, the Shares will be forfeited by the Grantee and all of the Grantee’s rights to such Shares shall immediately terminate without any payment or consideration by the Company. 4.Evidence of Stock. The Restricted Stock may be credited to the Grantee in book entry form and held, along with any Additional Securities (as defined below and which shall also constitute “Restricted Stock” under this Agreement), in custody by the Company or an agent for the Company until the applicable restrictions have expired and the Grantee provides other instructions. If any certificates are issued for Restricted Stock during any Period of Restriction, such certificates shall bear an appropriate legend as determined by the Company referring to the applicable terms, conditions and restrictions and the Grantee shall deliver such certificate(s). 5.Distributions. The Company shall disburse to the Grantee all dividends and other distributions paid or made in cash with respect to the Shares and Additional Securities (whether vested or not), less any applicable withholding obligations, in one lump sum payment, within 30 days after the date the Shares (or Additional Securities) with respect to which the dividends or distributions were made become vested. If the Shares or Additional Securities are forfeited without becoming vested, any such dividends or distributions also will be forfeited and the Grantee shall have no right to such dividends or distributions. 6.Taxes. The Grantee shall, as Shares of Restricted Stock vest, or at the time withholding is otherwise required by any Applicable Law (including in the event Grantee coordinates with the Company to make a timely election pursuant to Section 83(b) of the Code), pay the Company the amount necessary to satisfy any applicable foreign, federal, state, and local income and employment tax withholding obligations in a form of payment acceptable to the Company. The Company will withhold that portion of Grantee’s vested Shares to cover the applicable withholding tax liability unless Grantee notifies the Company that Grantee desires to elect to pay the applicable withholding tax liability by other means at least five business days prior to the applicable vesting date and in a form of payment acceptable to the Company. -------------------------------------------------------------------------------- 7.Additional Securities. Any securities received as the result of ownership of the Restricted Stock (the “Additional Securities”), including, but not by way of limitation, warrants, options and securities received as a stock dividend or in a stock split, or as a result of a recapitalization or reorganization or other similar change in the Company’s capital structure, shall be retained in book entry form in the same manner and subject to the same conditions and restrictions as the Shares of Restricted Stock with respect to which they were issued, including, without limitation, the Vesting Schedule set forth in the Notice and the forfeiture provisions set forth in Section 8. The Grantee shall be entitled to direct the Company to exercise any warrant, option or other right received as Additional Securities upon supplying the funds necessary to do so, in which event the securities so purchased shall constitute Additional Securities, but the Grantee may not direct the Company to sell any such warrant, option or right. If Additional Securities consist of a convertible security, the Grantee may exercise any conversion right, and any securities so acquired shall constitute Additional Securities. 8.Forfeiture of Shares. If the Grantee’s Continuous Service terminates prior to the vesting of any Shares for any reason, with or without Cause (including death or disability), then all of the unvested Shares of Restricted Stock shall automatically be deemed forfeited to the Company upon such termination of Continuous Service, without any action by the Company or Grantee and without any consideration due or payable to Grantee, and Grantee shall cease to have any further right, title or interest in the forfeited Restricted Stock. Upon forfeiture, the Company and/or its assigns shall become the legal and beneficial owner of the Shares forfeited and all rights and interest thereon or related thereto, and the Company shall have the right to transfer to its own name or its assigns the number of Shares forfeited, without any action by the Grantee. 9.Stop-Transfer Notices. In order to ensure compliance with the restrictions on transfer set forth in this Agreement, the Notice or the Plan, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 10.Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 11.Restrictive Legends. Grantee understands and agrees that the Company may cause the legend set forth below or legends substantially equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares, if applicable, together with any other legends that may be required by the Company or by state or federal securities laws: THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER, INCLUDING POSSIBLE FORFEITURE, AS SET FORTH IN THE RESTRICTED STOCK AWARD AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER AND SUCH TRANSFER RESTRICTIONS, INCLUDING POSSIBLE FORFEITURE, ARE BINDING ON TRANSFEREES OF THESE SHARES. 12.Transferability. No benefit payable under, or interest in, this Agreement or in the Shares that are scheduled to be issued hereunder shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge and any such attempted action shall be void and no such benefit or interest shall be, in any manner, liable for, or subject to, your or your beneficiary’s debts, contracts, liabilities or torts; provided, however, nothing in this Section 12 shall prevent transfer by will or by applicable laws of descent and distribution, as further described in Section 14 of the Plan. 13.No Contract for Employment. This Agreement is not an employment or service contract and nothing in this Agreement shall be deemed to create in any way whatsoever any obligation of the Grantee to continue in the employ or service of the Company, or of the Company to continue to employ Grantee. -------------------------------------------------------------------------------- 14.Applicability of Plan. This Agreement is subject to all the provisions of the Plan, which provisions are hereby made a part of this Agreement, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of this Agreement and those of the Plan, the provisions of the Plan shall control. 15.No Compensation Deferral. This Award is not intended to constitute “nonqualified deferred compensation” within the meaning of Section 409A. To the extent that the Award is nevertheless deemed to be subject to the acceleration of tax imposed under Section 409A for any reason, this Award shall be interpreted in accordance with Section 409A. Notwithstanding any provision herein to the contrary, in the event that following the Grant Date, the Committee determines that the Award may be or become subject to the acceleration of tax imposed under Section 409A, the Committee may adopt such amendments to the Plan and/or this Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Committee determines are necessary or appropriate to (a) preserve the intended tax treatment of the benefits provided with respect to this Award, or (b) comply with the requirements of Section 409A to avoid the acceleration of tax thereunder. Any such action may include, but is not limited to, delaying payment, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A, to a Grantee who is a “specified employee” within the meaning of Section 409A to the first day following the six-month period (or, if earlier, the date of the Grantee’s death) after the date of the Grantee’s “separation of service” as defined in Section 409A. The Company shall use commercially reasonable efforts to implement the provisions of this Section 15 in good faith; provided that neither the Company, the Committee nor any Employee, Director or representative of the Company or of any of its Affiliates shall have any liability to Grantee with respect to this Section 15. 16.Acknowledgement. The Company may, in its sole discretion, decide to deliver any documents related to Awards awarded under the Plan or future Awards that may be awarded under the Plan by electronic means or request your consent to participate in the Plan by electronic means. You hereby consent to receive such documents by electronic delivery and agree to participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated by the Company. 17.Entire Agreement: Governing Law. The Notice, the Plan, this Agreement, and any Employment Agreement, constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and the Grantee with respect to the subject matter hereof, and may not be modified adversely to the Grantee’s interest except by means of a writing signed by the Company and the Grantee. In the event of any conflict between the terms set forth in the Notice or this Agreement and in the Plan, the terms of this Agreement shall control. These agreements are to be construed in accordance with and governed by the State of Delaware, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Plan to the substantive law of another jurisdiction. Should any provision of the Notice or this Agreement be determined by a court of law to be illegal or unenforceable, the other provisions shall nevertheless remain effective and shall remain enforceable. 18.Headings. The captions used in this Agreement are inserted for convenience and shall not be deemed a part of this Agreement for construction or interpretation. 19.Dispute Resolution. The provisions of this Section 19 shall be the exclusive means of resolving disputes arising out of or relating to the Notice, the Plan and this Agreement. The Company, the Grantee, and the Grantee’s assignees (the “parties”) shall attempt in good faith to resolve any disputes arising out of or relating to the Notice, the Plan and this Agreement by negotiation between individuals who have authority to settle the controversy. Negotiations shall be commenced by either party by notice of a written statement of the party’s position and the name and title of the individual who will represent the party. Within 30 days of the written notification, the parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to resolve the dispute. If the dispute is not resolved by negotiation within 90 days of the written notification, the parties agree that any suit, action, or proceeding arising out of or relating to the Notice, the Plan or this Agreement shall be brought in the United States District Court for the District of Colorado (or should such court lack jurisdiction to hear such action, suit or proceeding, in a Colorado state court located in City and County of Denver, Colorado) and that the parties shall submit to the jurisdiction of such court. The parties irrevocably waive, to the fullest extent permitted by law, any objection the party may have to -------------------------------------------------------------------------------- the laying of venue for any such suit, action or proceeding brought in such court. The parties also expressly waive any right they have or may have to a jury trial of any such suit, action or proceeding. If any one or more provisions of this Section 19 shall for any reason be held invalid or unenforceable, it is the specific intent of the parties that such provisions shall be modified to the minimum extent necessary to make it or its application valid and enforceable. 20.Compliance with Laws. Notwithstanding anything contained in this Agreement or the Plan, the Company may not take any actions hereunder, and no award shall be granted, that would violate the Securities Act of 1933, as amended (the “Act”), the Exchange Act, the Code, or any other securities or tax or other Applicable Law or regulation. Notwithstanding anything to the contrary contained herein, the Shares issuable upon vesting shall not be issued unless such Shares are then registered under the Act, or, if such Shares are not then so registered, the Company has determined that such vesting and issuance would be exempt from the registration requirements of the Act. 21.Notices. Any notice required or permitted hereunder shall be given in writing and shall be deemed effectively given upon personal delivery, upon transmission via facsimile or email with confirmation of successful transmission by the sending machine or upon deposit in the United States mail by certified mail (if the parties are within the United States) or upon deposit for delivery by an internationally recognized express mail courier service (for international delivery of notice), with postage and fees prepaid, addressed to the other party at its address as set forth in the Notice, or to such other address as such party may designate in writing from time to time to the other party. If an on-line or electronic system is established for participants in the Plan as described in Section 16 of this Agreement, effective notice may also be given and governed by the notice provisions of such on-line or electronic system. 22.Further Assurances. The parties agree to execute such further instruments and to take such further action as may reasonably be necessary to carry out the intent of this Agreement. 23.Counterparts. This Agreement may be signed in two counterparts, each of which will be an original, but both of which will constitute one and the same instrument.

LONG TERM INCENTIVE PLAN UNDER THE 2017 OMNIBUS INCENTIVE PLAN Performance Stock Unit Agreement Terms and Conditions 1.Award of Performance Stock Units. The Company hereby confirms the grant to you, as of the Grant Date and subject to the terms and conditions of this Agreement, the LTIP and the Omnibus Plan, of an award of Performance Stock Units (the “Units”) in an amount initially equal to the Target Number of Performance Stock Units specified on the cover page of this Agreement. The number of Units that may actually be earned and become eligible to vest pursuant to this Award can be between 0% and 200% of the Target Number of Units, but may not (except for any Dividend Equivalent Units credited to you pursuant to Section 6 below) exceed the Maximum Number of Performance Stock Units specified on the cover page of this Agreement. Each Unit that is earned as a result of the performance goals specified in Appendix A to this Agreement having been satisfied and which thereafter vests represents the right to receive one Share of the Company’s common stock. Prior to their settlement or forfeiture in accordance with the terms of this Agreement, the Units granted to you will be credited to a performance stock unit account in your name maintained by the Company. This account will be unfunded and maintained for book-keeping purposes only, with the Units simply representing an unfunded and unsecured contingent obligation of the Company. 2.Restrictions Applicable to Units. Neither this Award nor the Units subject to this Award may be sold, assigned, transferred, exchanged or encumbered, voluntarily or involuntarily, other than (i) a transfer upon your death in accordance with your will, by the laws of descent and distribution or pursuant to a beneficiary designation submitted in accordance with Section 6.5 of the LTIP, or (ii) to the extent allowed by the Committee, pursuant to a domestic relations order. Following any such transfer, this Award shall continue to be subject to the same terms and conditions that were applicable to the Award immediately prior to its transfer. Any attempted transfer in violation of this Section 2 shall be void and without effect. The Units and your right to receive Shares in settlement of any Units under this Agreement shall be subject to forfeiture except to extent the Units have been earned and thereafter vest as provided in Sections 4 and 5. 3.No Shareholder Rights. The Units subject to this Award do not entitle you to any rights of a holder of the Company’s common stock. You will not have any of the rights of a shareholder of the Company in connection with any Units granted or earned pursuant to this Agreement unless and until Shares are issued to you in settlement of earned and vested Units as provided in Section 5. 4.Vesting and Forfeiture of Units. Subject in all cases to Section 8 of this Agreement, the Units shall vest at the earliest of the following times and to the degree specified. a.Scheduled Vesting. The number of Units that have been earned during the Performance Period, as determined by the Committee in accordance with Appendix A, will vest on the Scheduled Vesting Date, so long as your Continuous Service has been continuous from the Grant Date to the Scheduled Vesting Date. For these purposes, the “Scheduled Vesting Date” means the date the Committee certifies (i) the degree to which the applicable performance goals for the Performance Period have been satisfied, and (ii) the number of Units that have been earned during the Performance Period as determined in accordance Appendix A, which certification shall occur no later than March 10 of the calendar year immediately following the calendar year during which the Performance Period ended. (b) -------------------------------------------------------------------------------- b.Disability. If your Continuous Service terminates by reason of your Disability prior to the Scheduled Vesting Date, then you will be entitled to have vest on the date your Continuous Service terminated a pro rata portion of the Target Number of Units specified on the cover page of this Agreement. The pro rata portion shall be determined by multiplying your Target Number of Performance Stock Units by a fraction whose numerator is the number of days during the Performance Period prior to your employment termination date and whose denominator is the number of days in the Performance Period. c.Death. If your Continuous Service terminates by reason of your death prior to the Scheduled Vesting Date, then you will be entitled to have vest on the date your Continuous Service terminates a pro rata portion of the Target Number of Units specified on the cover page of this Agreement. The pro rata portion shall be determined in the same manner as provided in Section 4(b) above. d.Retirement. If your Continuous Service terminates by reason of your Retirement (as defined in Section 9 below) prior to the Scheduled Vesting Date, then you will be entitled to have vest on the Scheduled Vesting Date a pro rata portion of the Units that would otherwise have been determined to have been earned during the Performance Period in accordance with Appendix A if your Continuous Service had been continuous until the Scheduled Vesting Date. The pro rata portion shall be determined in the same manner as provided in Section 4(b) above. e.Qualifying Termination. If your Continuous Service terminates prior to the Scheduled Vesting Date, and if such termination of Continuous Service constitutes a Qualifying Termination (as defined in Section 9 below), then you will be entitled to have vest on the Scheduled Vesting Date a pro rata portion of the Units that would otherwise have been determined to have been earned during the Performance Period in accordance with Appendix A if your Continuous Service had been continuous until the Scheduled Vesting Date. The pro rata portion shall be determined in the same manner as provided in Section 4(b). f.Change in Control. If a Change in Control occurs after the Grant Date but before the Scheduled Vesting Date and your Continuous Service continues to the date of the Change in Control, then the Performance Period will be truncated and will end as of the date of the Change in Control. You will be entitled to have vest as of the date of the Change in Control the number of Units that are determined to have been earned based on actual performance against the performance goals specified in Appendix A over the truncated Performance Period. g.Forfeiture of Unvested Units. To the extent any of Sections 4(a) through (f) is applicable to this Award, any Units that do not vest on the applicable vesting date as provided therein shall immediately be forfeited. If your employment terminates prior to the Scheduled Vesting Date under circumstances other than as set forth in Sections 4(b) through (f), all unvested Units shall immediately be forfeited. 5.Settlement of Units. Subject to Section 8 below, as soon as practicable after any date on which Units vest (but no later than the 15th day of the third calendar month following the vesting date), the Company shall cause to be issued and delivered to you (or to your personal representative or your designated beneficiary or estate in the event of your death, as applicable) one Share in payment and settlement of each vested Unit. Delivery of the Shares shall be effected by the issuance of a stock certificate to you, by an appropriate entry in the stock register maintained by the Company’s transfer agent with a notice of issuance provided to you, or by the electronic delivery of the Shares to a brokerage account you designate, and shall be subject to the tax withholding provisions of Section 7 and compliance with all applicable legal requirements as provided in the Omnibus Plan and LTIP, and shall be in complete satisfaction and settlement of such vested Units. The Company will pay any original issue or -------------------------------------------------------------------------------- transfer taxes with respect to the issue and transfer of Shares to you pursuant to this Agreement, and all fees and expenses incurred by it in connection therewith. If the Units that vest include a fractional Unit, the Company shall round the number of vested Units to the nearest whole Unit prior to issuance of Shares as provided herein. 6.Dividend Equivalents. If the Company pays cash dividends on its Shares while any Units subject to this Agreement are outstanding, then on the date this Award vests pursuant to Section 4 above, a Total Dividend Equivalent amount will be credited to your performance stock unit account and shall be deemed reinvested in additional Units (“Dividend Equivalent Units”). The Total Dividend Equivalent amount will be determined by multiplying the number of underlying Units determined to have vested by the per share amount of each cash dividend paid on the Company’s common stock with a record date and payment date occurring between the Grant Date and the applicable vesting date, and adding those products together. Each of those products is referred to as a “Dividend Equivalent Amount.” The number of Dividend Equivalent Units to be credited to your performance stock unit account pursuant to this deemed reinvestment will be determined by dividing each Dividend Equivalent Amount by the Fair Market Value of a share of the Company’s common stock on the applicable dividend payment date and adding those quotients together. Any Dividend Equivalent Units so credited will be fully vested and subject to settlement with the underlying Units as provided in Section 5 above. 7.Tax Consequences and Withholding. No Shares will be delivered to you in settlement of vested Units unless you have made arrangements acceptable to the Company for payment of any federal, state, local or foreign withholding taxes that may be due as a result of the delivery of the Shares. You hereby authorize the Company (or any Affiliate) to withhold from payroll or other amounts payable to you any sums required to satisfy such withholding tax obligations, and otherwise agree to satisfy such obligations in accordance with the provisions of Section 17 of the Omnibus Incentive Plan. You may elect to satisfy such withholding tax obligations by having the Company withhold a number of Shares that would otherwise be issued to you in settlement of the Units and that have a fair market value equal to the amount of such withholding tax obligations by notifying the Company of such election prior to the Vesting Date. 8.Forfeiture of Award and Compensation Recovery a.Forfeiture Conditions. Notwithstanding anything to the contrary in this Agreement, if your Continuous Service is terminated for Cause, or if, during the term of your Continuous Service with the Company and its Subsidiaries and for one year after such Continuous Service ends (the “Restricted Period”), you breach any of the restrictive covenants contained in your employment agreement, if any, then (i) you shall immediately forfeit this Award and any right to receive Shares that have not yet been issued pursuant to Section 5, and (ii) with respect to Shares that have been issued pursuant to this Award, either (A) you shall return such Shares to the Company, or (B) you shall pay to the Company in cash an amount equal to the Fair Market Value of such Shares as of the respective vesting date of the underlying Units. b.Compensation Recovery Policy. In addition to the provisions in Sections 8(a), to the extent that this Award and any compensation associated therewith is considered “incentive-based compensation” within the meaning and subject to the requirements of Section 10D of the Exchange Act, this Award and any compensation associated therewith shall be subject to potential forfeiture or recovery by the Company in accordance with any compensation recovery policy adopted by the Board or the Committee in response to the requirements of Section 10D of the Exchange Act and any implementing rules and regulations thereunder adopted by the Securities and Exchange Commission or any national securities exchange on which the Company’s Shares are then listed. This Agreement may be unilaterally amended by the Committee to comply with any such compensation recovery policy. -------------------------------------------------------------------------------- c.Remedies.

Notwithstanding the foregoing, any change in (ii) that applies in substantially the same manner to similarly situated Participants will not be deemed to be Good Reason. b.Qualifying Termination. “Qualifying Termination” means you cease to be an Employee (or other Company service provider) due either to an involuntary termination for reasons other than Cause or a resignation for Good Reason. c.Cause. “Cause” means “Cause” as defined in the Omnibus Plan. d.Disability. “Disability” means that you are unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months. e.Retirement. “Retirement” means a termination of your Continuous Service, other than for Cause, occurring at or after age 65. 10.Notices.

EX-95 11 exhibit95-minesafety2023.htm EX-95 EXHIBIT 95 Mine Safety and Health Administration Safety Data We are committed to maintaining a safe work environment and working to ensure environmental compliance across all of our operations. The health and safety of our employees and limiting the impact to communities in which we operate are critical to our long-term success. We employ practices and conduct training to help ensure that our employees work safely. Furthermore, we utilize processes for managing, monitoring and improving safety and environmental performance. The following disclosures are provided pursuant to Securities and Exchange Commission (SEC) regulations, which require certain disclosures by companies required to file periodic reports under the Securities Exchange Act of 1934, as amended, that operate coal mines regulated under the Federal Mine Safety and Health Act of 1977 (the "Mine Act"). The disclosures reflect United States (U.S.) mining operations only. Mine Safety Information. Whenever the Mine Safety and Health Administration (MSHA) believes that a violation of the Mine Act, any health or safety standard, or any regulation has occurred, it may issue a violation which describes the associated condition or practice and designates a time frame within which the operator must abate the violation. In some situations, such as when MSHA believes that conditions pose a hazard to miners, MSHA may issue an order removing miners from the area of the mine affected by the condition until hazards are corrected. Whenever MSHA issues a citation or order, it generally proposes a civil penalty, or fine, as a result of the violation that the operator is ordered to pay. Citations and orders can be contested and appealed and, as part of that process, are often reduced in severity and amount, and are sometimes vacated. The number of citations, orders and proposed assessments vary depending on the size and type (underground or surface) of the company and mine. We are required to report citations and orders issued to us by MSHA during the year ended December 31, 2023, as reflected in our systems. Our required disclosure covers only those mines that were issued orders or citations during the period presented and, commensurate with SEC regulations, does not reflect orders or citations issued to independent contractors working at our mines. Due to timing and other factors, our data may not agree with the mine data retrieval system maintained by MSHA. The proposed assessments for the year ended December 31, 2023 were taken from the MSHA system as of March 8, 2024. Additional information about MSHA references we are required to report is as follows: •Section 104 S&S Violations: The total number of violations received from MSHA under section 104(a) of the Mine Act that could significantly and substantially contribute to a serious injury if left unabated. •Section 104(b)Orders: The total number of orders issued by MSHA under section 104(b) of the Mine Act, which represents a failure to abate a citation under section 104(a) within the period of time prescribed by MSHA. This results in an order of immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been abated. •Section 104(d) Citations and Orders: The total number of citations and orders issued by MSHA under section 104(d) of the Mine Act for unwarrantable failure to comply with mandatory health or safety standards. •• Section 104(e) Notices: The total number of notices issued by MSHA under section 104(e) of the Mine Act for a pattern of violations that could contribute to mine health or safety hazards. •Section 110(b)(2)Violations: The total number of flagrant violations issued by MSHA under section 110(b)(2) of the Mine Act. •Section 107(a) Orders: The total number of orders issued by MSHA under section 107(a) of the Mine Act for situations in which MSHA determined an imminent danger existed. •Proposed MSHA Assessments: The total dollar value of proposed assessments from MSHA. •Fatalities: The total number of mining-related fatalities. Our first mine is located in the Gulf Coast Lignite Region, in Natchitoches Parish, Louisiana (the "Five Forks Mine"). For the year ended December 31, 2023, there were no reportable citations or orders issued to the Five Forks Mine. Our second mine is located in Knox, Kentucky ("Corbin Project"). For the year ended December 31, 2023, there were no reportable citations or orders issued to Corbin Project. Our third mine is located in Mingo, West Virginia ("Mine Four"). For the year ended December 31, 2023, there were no reportable citations or orders issued to Mine Four. Pending Legal Actions. The Federal Mine Safety and Health Review Commission (the "Commission") is an independent adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act. These cases may involve, among other questions, challenges by operators to citations, orders and penalties they have received from MSHA, or complaints of discrimination by miners under section 105 of the Mine Act. The following is a brief description of the types of legal actions that may be brought before the Commission. -------------------------------------------------------------------------------- •Contests of Citations and Orders: A contest proceeding may be filed with the Commission by operators, miners or miners’ representatives to challenge the issuance of a citation or order issued by MSHA, including citations related to disputed provisions of operators' emergency response plans. •Contests of Proposed Penalties (Petitions for Assessment of Penalties): A contest of a proposed penalty is an administrative proceeding before the Commission challenging a civil penalty that MSHA has proposed for the violation. Such proceedings may also involve appeals of judges' decisions or orders to the Commission on proposed penalties, including petitions for discretionary review and review by the Commission on its own motion. •Complaints for Compensation: A complaint for compensation may be filed with the Commission by miners entitled to compensation when a mine is closed by certain withdrawal orders issued by MSHA. The purpose of the proceeding is to determine the amount of compensation, if any, due miners idled by the orders. •Complaints of Discharge, Discrimination or Interference: A discrimination proceeding is a case that involves a miner’s allegation that he or she has suffered a wrong by the operator because he or she engaged in some type of activity protected under the Mine Act, such as making a safety complaint. This category includes temporary reinstatement proceedings, which involve cases in which a miner has filed a complaint with MSHA stating he or she has suffered discrimination and the miner has lost his or her position. •Applications for Temporary Relief: An application for temporary relief from any modification or termination of any order or from any order issued under certain subparts of section 104 of the Mine Act may be filed with the Commission at any time before such order becomes final. For the year ended December 31, 2023, there were no pending or legal actions before the Commission at Five Forks Mine, Corbin Project or Mine Four. EX-97 12 exhibit97clawbackpolicy.htm EX-97 Exhibit 97 Advanced Emissions Solutions, Inc. COMPENSATION RECOUPMENT (CLAWBACK) POLICY Recoupment of Incentive-Based Compensation It is the policy of Advanced Emissions Solutions, Inc. (the “Company”) that, in the event the Company is required to prepare an accounting restatement of the Company’s financial statements due to the Company’s material non-compliance with any financial reporting requirement under the federal securities laws (including any such correction that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period), the Company will recover on a reasonably prompt basis the amount of any Incentive-Based Compensation Received by a Covered Executive during the Recovery Period that exceeds the amount that otherwise would have been Received had it been determined based on the restated financial statements. Policy Administration and Definitions This Policy is administered by the Compensation Committee (the “Committee”) of the Company’s Board of Directors and is intended to comply with, and as applicable to be administered and interpreted consistent with, and subject to the exceptions set forth in, Listing Standard 5608 adopted by The Nasdaq Stock Market to implement Rule 10D-1 under the Securities Exchange Act of 1934, as amended (collectively, “Rule 10D-1”). For purposes of this Policy: “Incentive-Based Compensation” means any compensation granted, earned, or vested based in whole or in part on the Company’s attainment of a financial reporting measure that was Received by a person (i) on or after October 2, 2023 and after the person began service as a Covered Executive, and (ii) who served as a Covered Executive at any time during the performance period for the Incentive-Based Compensation. A financial reporting measure is (i) any measure that is determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements and any measure derived wholly or in part from such a measure, and (ii) any measure based in whole or in part on the Company’s stock price or total shareholder return. Incentive-Based Compensation is deemed to be “Received” in the fiscal period during which the relevant financial reporting measure is attained, regardless of when the compensation is actually paid or awarded. “Covered Executive” means any “executive officer” of the Company as defined under Rule 10D-1. “Recovery Period” means the three completed fiscal years immediately preceding the date that the Company is required to prepare the accounting restatement described in this Policy, all as determined pursuant to Rule 10D-1, and any transition period of less than nine months that is within or immediately following such three fiscal years. If the Committee determines the amount of Incentive-Based Compensation Received by a Covered Executive during a Recovery Period exceeds the amount that would have been Received if determined or calculated based on the Company’s restated financial results, such excess amount of Incentive-Based Compensation shall be subject to recoupment by the Company pursuant to this Policy. For Incentive-Based Compensation based on stock price or total 1 -------------------------------------------------------------------------------- shareholder return, where the amount of erroneously awarded compensation is not subject to mathematical recalculation directly from the information in an accounting restatement, the Committee will determine the amount based on a reasonable estimate of the effect of the accounting restatement on the relevant stock price or total shareholder return. In all cases, the calculation of the excess amount of Incentive-Based Compensation to be recovered will be determined without regard to any taxes paid with respect to such compensation. The Company will maintain and will provide to The Nasdaq Stock Market documentation of all determinations and actions taken in complying with this Policy. Any determinations made by the Committee under this Policy shall be final and binding on all affected individuals. The Company may effect any recovery pursuant to this Policy by requiring payment of such amount(s) to the Company, by set-off, by reducing future compensation, or by such other means or combination of means as the Committee determines to be appropriate. The Company need not recover the excess amount of Incentive-Based Compensation if and to the extent that the Committee determines that such recovery is impracticable, subject to and in accordance with any applicable exceptions under The Nasdaq Stock Market listing rules, and not required under Rule 10D-1, including if the Committee determines that the direct expense paid to a third party to assist in enforcing this Policy would exceed the amount to be recovered after making a reasonable attempt to recover such amounts. The Company is authorized to take appropriate steps to implement this Policy with respect to Incentive-Based Compensation arrangements with Covered Executives. Any right of recoupment or recovery pursuant to this Policy is in addition to, and not in lieu of, any other remedies or rights of recoupment that may be available to the Company pursuant to the terms of any other policy, any employment agreement or plan or award terms, and any other legal remedies available to the Company; provided that the Company shall not recoup amounts pursuant to such other policy, terms or remedies to the extent it is recovered pursuant to this Policy. The Company shall not indemnify any Covered Executive against the loss of any Incentive-Based Compensation (or provide any advancement of expenses in such instance), including any payment or reimbursement for the cost of third-party insurance purchased by any Covered Executives to fund potential recovery obligations under this Policy. 2 -------------------------------------------------------------------------------- ADVANCED EMISSIONS SOLUTIONS, INC.
