(NASDAQ: ARQ) (the 'Company' or 'Arq'), a producer of activated carbon and other environmentally efficient carbon products for use in purification and sustainable materials, today announced its financial and operating results for the quarter and year ended December 31, 2025. Financial Highlights Generated revenue of $120.3 million in FY 2025 ($29.4 million in Q4 2025), up 10% over the prior year, driven largely by positive changes in product mix and overall volumesGross margin of 27.9% in FY 2025 vs. 36.2% in FY 2024, driven by higher costs directly related to granular activated carbon ('GAC') start-up costsGross margin in Q4 2025 of 13.6% vs. 36.3% in Q4 2024, reflecting negative impact of GAC start-up costsRecorded non-cash impairment charge of $45 million related to Corbin assets in Q4 2025, reflecting the temporary idling of the Corbin facility.Reported Net loss of $52.6 million in FY 2025, versus a Net loss of $5.1 million in FY 2024; Q4 2025 Net loss of $50.0 million vs. Net loss of $1.3 million in Q4 2024Adjusted EBITDA of $13.2 million in FY 2025 vs. Adjusted EBITDA of $10.5 million in the prior year(1); Adjusted EBITDA of $0.3 million in Q4 2025 vs. $2.8 million in the prior year period(1), reflecting negative impact of certain GAC start-up costsExited 2025 with cash and restricted cash of $15.0 million, including $8.5 million restricted cashCapital expenditures for FY 2025 totaled $8.6 million (1) Adjusted EBITDA is a non-GAAP financial measure. Please refer to the paragraph titled 'Non-GAAP Measures' for the definitions of non-GAAP financial measures and reconciliations to GAAP measures included in this press release. Recent Business Highlights Pausing GAC production and development to conduct comprehensive engineering and production process optimization review of the Company's GAC businessDelivered record powdered activated carbon ('PAC') business performance with over 117 million pounds of volume for FY 2025Achieved record revenues of $120 million for FY 2025, driven by PAC businessAchieved record Adjusted EBITDA of $13 million for FY 2025 GAC Strategy Updates Arq announced today its decision to pause GAC production to conduct a comprehensive engineering and production process optimization review of the path forward for the Company's GAC business. As a result, the Company does not expect any GAC production in fiscal year 2026. This decision follows independent testing results received in late January 2026 showing the Company's current thermal oxidizer can only support approximately 15 million pounds of annual GAC production and would require additional modifications to achieve our original target of 25 million pounds of annual GAC production or higher. The Company's analysis indicates that a 15 million pound scenario does not deliver acceptable returns and volumes above that amount are required to generate attractive economic returns. The optimization review will determine production scale, capital requirements, and return profiles, all of which need to be finalized before the Company will commit additional investment. These constraints emerged as the Company prepared to transition from its Corbin Wetcake feedstock to bituminous proven performance coal feedstock from other sources, a solution which is expected to address previously announced design challenges. The thermal oxidizer issues and their impact on capacity stem from design flaws by the Company's original engineering consultant, with whom Arq remains in litigation. As a result of the decision to transition away from using Corbin Wetcake for its GAC products, the Company is temporarily idling its Corbin facility and in connection recorded a non-cash impairment charge of $45 million in Q4 2025. Alternative applications for Corbin Wetcake, including asphalt emulsion blending, continue to advance. Leadership Updates Arq has appointed Eric Robinson as VP Operations, effective immediately. Mr. Robinson brings more than 30 years of industrial facilities experience and previously revitalized Arq's Red River plant in 2012, driving a 20% yield improvement, doubling production, and significantly increasing plant availability. His expertise in plant optimization and ramp-up challenges makes him well-suited to lead operational focus during this assessment period. An on-site process engineer with technical oversight has also been appointed, reporting directly to Mr. Robinson. As a result of the Company's decision to idle its Corbin facility, making Arq a single-plant business, and Mr. Robinson stepping into the VP Operations role, the Company has eliminated the Chief Operating Officer role. Deke Williamson will depart the Company, effective April 18, 2026, after playing a pivotal role in enhancing PAC operations to their current profitable state. 'As we move into this next phase, Eric's proven track record at our Red River facility makes him the right man for the job. With these changes, I believe we are well-positioned to execute our PAC business plan and complete our GAC optimization review.' The Company has also made changes to its finance organization. Jay Voncannon will no longer serve as the Company's Chief Financial Officer, effective immediately. Anthony Nathan, who brings eight years of experience with Arq including oversight of all recent equity and credit financings and the Arq Limited/ADES combination (now Arq Inc), has been promoted to VP Finance, where he will oversee strategic planning, financial analysis, budgeting and investor relations. Stacia Hansen continues in her role as Chief Accounting Officer and will also serve as the Company's principal financial officer. Financial Guidance Arq is providing detailed operational and financial guidance for the first time to enhance investor transparency. For fiscal year 2026, Arq expects revenue of $120-125 million. Adjusted EBITDA is projected to be $17-20 million. These projections assume no GAC contribution given the strategic operational changes outlined above. The Company is also providing operational metrics for the first time: PAC average selling price ('ASP') is expected to be $0.88-0.91 per pound (compared to $0.89 in 2025 and $0.82 in 2024) and production volumes are projected at 122-125 million pounds (compared to over 117 million pounds in 2025 and 111 million pounds in 2024). Additional revenue from other chemicals and products is expected to contribute approximately 13-15% of total revenue, generally consistent with prior years. Arq's product portfolio includes a wide range of pricing tiers, including specialty products and engineered materials commanding significant premiums over standardized industrial products. Achieving maximum value at the lowest possible cost for every pound that is produced at the Red River facility remains the objective. That was, and remains, the basis for adding GAC production capacity and is also why the optimization review is essential to determine the optimal production volume and mix that will maximize value. It is also why the impact of the GAC start-up costs (in large part due to design issues by the Company's former engineering consultant) has had such a significant negative effect on the Company's financial performance in the last two quarters. As a result of GAC production delays, the Company has and will be able to take advantage of additional furnace capacity to produce PAC, which, combined with operational efficiencies, is expected to enable higher PAC production volumes than previously anticipated. Management expects that PAC production levels can be maintained or expanded until such time as a clear path forward on the Company's GAC business is defined, providing operational flexibility and revenue optimization opportunities. The 2026 guidance incorporates the Company's routine biennial two-week maintenance turnaround at the Red River plant, which is scheduled to occur in April. Management Commentary 'Today's results reflect Arq's ongoing evolution and a fundamental reset in our approach,' said Mr. Rasmus. 'We believe the decision to pause development of our GAC line is in the best interests of shareholders. While the transition from Corbin-derived feedstock to purchased coal resolves a major operational challenge due to design flaws that constrained our GAC production process, the subsequent testing we have conducted this year has revealed yet another challenge stemming from original design flaws. While I remain confident in our ability to navigate these operational setbacks, we must be certain of the ultimate cost to reach a nameplate capacity that delivers acceptable returns before spending further capital on the project. After evaluating our options, we have therefore concluded that the most prudent path forward is to pause and ensure we are building a plant of optimized scale and attractive economics. GAC market fundamentals remain strong, and our customer relationships remain robust, validating both the market opportunity and our strategic approach.' Mr. Rasmus continued, 'Our foundational PAC business delivered record performance in 2025 with revenues of approximately $120 million, up 10% year-over-year, while Adjusted EBITDA of $13 million represented a 26% improvement despite GAC start-up costs significantly impacting profitability. This demonstrates the benefits of our strategic transformation - sustained volume growth, enhanced product mix, and continued pricing strength as we capture higher-value, higher-margin applications beyond traditional power markets. PAC is now delivering better financial performance than previously expected. While never our end goal, it ensures our downside is protected while upside optionality remains. The PAC business has funded its own turnaround while supporting strategic growth initiatives, demonstrating operational strength and market position durability. While portions of the PAC market are impacted by various regulatory regimes, potential changes to such regulations are mitigated by our healthy orderbook: 96% contract visibility on 2026 volumes, with 75% and 43% visibility through 2027 and 2028 respectively. Our 2026 Adjusted EBITDA guidance of $17-20 million represents a 35-50% improvement on 2025.' Full Year 2025 Results Revenues totaled $120.3 million for full year 2025, compared to $109.0 million in the prior year. The revenue increase was primarily driven by improved ASP and product diversification into higher value end-markets. Cost of revenues totaled $86.8 million for full year 2025, compared to $69.5 million in the prior year. This increase in costs of revenue was primarily related to start-up costs associated with GAC production in Q3 and Q4 2025. Gross margin was 27.9% for full year 2025, compared to 36.2% in the prior year. The reduction was primarily driven by the impact of start-up costs associated with GAC production in Q3 and Q4 2025. Other operating expenses were $86.5 million for full year 2025, compared to $41.4 million in the prior year. The increase was mainly driven by non-cash impairment charges of $44.8 million related to our Corbin facility, and an increase in research and development costs relating to GAC start-up, partially offset by a material reduction in SG&A to $22.6 million compared to $28.7 million in the prior year. Operating loss totaled $53.0 million for full year 2025, compared to an operating loss of $2.0 million in the prior year. The increase in loss was mainly driven by the factors referenced above, especially the impairment charge. Interest expense was $2.4 million for full year 2025, compared to $3.3 million in the prior year. The reduction was primarily driven by lower average interest rates on our outstanding debt facilities. Net loss was $52.6 million, or $1.27 per diluted share for full year 2025, compared to Net loss of $5.1 million, or $0.14 per diluted share in the prior year. The increase in net loss was primarily driven by higher cost factors referenced above. Adjusted EBITDA was $13.2 million for full year 2025, compared to an Adjusted EBITDA of $10.5 million in the prior year. The increase was mainly driven by our continued focus on increasing revenues while lowering costs, including SG&A. Fourth Quarter 2025 Results Revenue totaled $29.4 million for the fourth quarter of 2025, reflecting an increase of 9% compared to $27.0 million in the prior year period. The increase was driven predominantly by enhanced volumes and pricing. ASP for the fourth quarter of 2025 were up approximately 7% compared to prior year period, marking the twelfth consecutive quarter of year-over-year percentage growth in ASP. Cost of revenue totaled $25.4 million for the fourth quarter of 2025, an increase of approximately 48% compared to $17.2 million in the prior year period. This increase was a direct consequence of start-up costs associated with GAC production. Gross margin reduced to 13.6% for the fourth quarter of 2025, compared to 36.3% in the prior year period. The reduction in gross margin was driven by higher costs associated with GAC start-up. Selling, general and administrative remained flat in Q4 2025 compared to the prior year period. Research and development costs totaled $1.2 million in the fourth quarter of 2025, compared to $0.7 million in the prior year period. This increase was primarily due to testing relating to initial GAC production. Operating loss was $51.2 million for the fourth quarter of 2025, compared to an operating income of $0.4 million in the prior year period. The reduction was mainly driven by the factors referenced above. Net loss was $50.0 million in the fourth quarter of 2025, or $1.20 per diluted share, compared to a net loss of $1.3 million, or $0.03 per diluted share, in the prior year period. The reduction was mainly driven by the factors referenced above. Adjusted EBITDA was $0.3 million for the fourth quarter of 2025, compared to Adjusted EBITDA of $3.8 million in the prior year period. The reduction was primarily driven by the significant one-off items discussed above. See note below regarding the use of the non-GAAP financial measure Adjusted EBITDA and a reconciliation to the most comparable GAAP financial measure. Capex and Balance Sheet Capital expenditures totaled $8.6 million for full year 2025, compared to $85.2 million in the prior year. The reduction was driven by the conclusion of expansion work at our Red River and Corbin facilities. In December 2024, the Company closed a $30 million ABL credit facility (the 'ABL Facility') with MidCap Financial, a leading commercial finance company focused on middle market transactions. Total available borrowing capacity for the ABL Facility is determined by a borrowing base calculation based on a certain percentage of eligible accounts receivable and inventory. Drawdown from the ABL Facility with MidCap Financial totaled $19.0 million as of December 31, 2025. Cash as of December 31, 2025, including $8.5 million of restricted cash, totaled $15.0 million, compared to $22.2 million as of December 31, 2024. The reduction was largely driven by increased expenditures relating to initial GAC production. Total debt, inclusive of financing leases, as of December 31, 2025, totaled $28.5 million compared to $24.8 million as of December 31, 2024. The increase was driven by increased utilization of the ABL Facility.

Investor Contact: Anthony Nathan, Arq Marc Silverberg, ICR [email protected] Note on Non-GAAP Financial Measures To supplement our financial information presented in accordance with U.S. Generally Accepted Accounting Principles ('U.S. GAAP'), we provide certain supplemental financial measures, including EBITDA and Adjusted EBITDA, which are measurements that are not calculated in accordance with U.S. 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 other non-cash gains, increased by cash distributions from equity method investments, share-based compensation expense, other non-cash losses and non-recurring costs and fees. EBITDA and Adjusted EBITDA should be considered in addition to, and not as a substitute for, net income (loss) in accordance with U.S. GAAP as a measure of performance. See below for a reconciliation from net income (loss), the nearest U.S. GAAP financial measure, to EBITDA and Adjusted EBITDA. We believe that the EBITDA and Adjusted EBITDA measures are less susceptible to variances that affect our 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. EBITDA and Adjusted EBITDA: The following table reconciles net loss, our most directly comparable as-reported financial measure calculated in accordance with U.S. GAAP, to (EBITDA Loss) EBITDA and Adjusted EBITDA.
