- Reported Net loss of $0.8 million in Q1 2026 vs. Net income of $0.2 million in Q1 2025
- Adjusted EBITDA(1) of $2.7 million in Q1 2026 vs. $4.1 million in Q1 2025, driven by factors outlined above
- Adjusted EBITDA for Q1 2026 included the negative impact of $0.8 million non-cash inventory revaluation charge for inventory produced in 2025

Recent Business & Other Highlights
- Successfully completed biennial plant turnaround and maintenance (TAR) under budget in April 2026
- Advanced GAC optimization review process with a well-regarded engineering firm and a new equipment design firm
- Progressed asphalt testing with leading U.S. asphalt company, with Corbin wetcake demonstrating differentiated performance characteristics and advancing to small in-field paving tests
- Board and management team ownership increased to more than 20% of the company following meaningful recent purchases
Strategic Optimization Update
Arq’s strategic optimization review remains ongoing as the Company evaluates the most practical path to economically attractive GAC production. Arq continues to work in combination with both an equipment and an engineering firm to further refine process design, capital requirements, and timing. Both firms were selected following extensive diligence to validate their independence, capabilities, and relevant industry expertise. In parallel, the Company is evaluating incremental activated carbon growth alternatives, such as adding reactivation or acid washing capacity, to ensure we are prioritizing the highest-return opportunities. The Company's current goal is to complete the strategic optimization review and have a go-forward GAC strategy in place by Q3 2026.
GAC market fundamentals remain strong and continue to support a favorable pricing environment. The Company is also engaged in active discussions with multiple parties regarding potential opportunities to monetize its Corbin Facility and related technologies. In asphalt, testing with a leading U.S. partner continues to progress, with Corbin wetcake demonstrating differentiated performance characteristics and the work advancing to small-scale in-field paving trials.
Management Commentary
“The first quarter provided a solid foundation for the year ahead and underscored the continued transformation of our PAC business," said Bob Rasmus, CEO of Arq. "Sales increased year-over-year, and gross margins in January and February were exceptionally strong reflecting a business no longer carrying the full burden of GAC production costs. While a March inventory revaluation charge and the carry-over of the remaining GAC costs impacted reported results, underlying performance in the first two months reflects a clear normalization of margins. We also completed our biennial plant maintenance in April ahead of time and under budget. We remain confident in reiterating our full year 2026 guidance of revenue between $120 - $125 million and Adjusted EBITDA of $17 - $20 million.”
Mr. Rasmus continued, “Our GAC optimization review remains underway with two design partners. While we are moving with urgency, we want to take the time necessary to deliver a functional design, a construction and production time frame and a fully costed plan. That work includes evaluating the project’s return profile, the most appropriate funding approach, and potential incremental growth opportunities, including additional reactivation or acid washing capacity at our existing Red River facilities. More broadly, GAC market fundamentals remain highly attractive as the EPA's April 2027 PFAS monitoring deadline approaches. At the same time, our PAC business has evolved into a consistently growing and meaningfully profitable platform with further upside through pricing in higher-value markets, and we continue to make encouraging progress in discussions around our Corbin asset, particularly in asphalt applications."
Mr. Rasmus concluded, “Taken together, we believe we have a profitable core business, multiple compelling avenues for growth, and a clear responsibility to pursue those opportunities in a manner that maximizes shareholder value. We are more aligned with shareholders than ever, with our Board and management team now collectively owning more than 20% of the Company following meaningful recent share purchases. We believe that alignment is important and reflects our confidence in the business, our strategy, and the opportunities ahead.”
First Quarter 2026 Results
Revenue totaled $29.1 million for the first quarter of 2026, reflecting an increase of 7% compared to $27.2 million in the prior year period. The increase was driven predominantly by enhanced sales volumes.
Cost of revenue totaled $19.1 million for the first quarter of 2026, an increase of approximately 10% compared to $17.3 million in the prior year period. This increase was primarily driven by $1.1 million of costs associated with additional chemical sales, $0.8 million of non-cash inventory revaluation and certain GAC carry-costs described above.
Gross margin totaled 34.2% for the first quarter of 2026, compared to 36.4% in the prior year period. The reduction in gross margin was primarily driven by decreases in pricing caused by product mix, the inventory revaluation noted previously, and trailing costs subsequent to pausing production at our GAC facility, partially offset by increased sales volumes.
Selling, general and administrative expenses totaled $7.4 million, compared to $6.1 million in the prior year period. The increase was primarily driven by increases in insurance, recruiting and legal fees.
Research and development costs remained flat for the first quarter of 2026 compared to the first quarter of 2025.
Operating loss was $1.0 million for the first quarter of 2026, compared to operating income of $0.7 million in the prior year period. Net loss was $0.8 million in the first quarter of 2026, or $0.02 per diluted share, compared to net income of $0.2 million in the prior year period. The reduction in both cases was driven by the factors above.
Adjusted EBITDA was $2.7 million for the first quarter of 2026, compared to Adjusted EBITDA of $4.1 million in the prior year period. The reduction was primarily driven by lower net income in the current year period.
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 $0.7 million for the first quarter of 2026, compared to $3.7 million in the prior year period. The decrease was driven by increased spend on completion and commissioning of the GAC facility during the first quarter of 2025.
Cash as of March 31, 2026, totaled $15.9 million, including $11.2 million of restricted cash, compared to $15.0 million as of December 31, 2025.
Total debt, inclusive of financing leases, as of March 31, 2026, totaled $30.2 million compared to $28.5 million as of December 31, 2025. The increase was driven primarily by increased borrowings on the Company’s revolving credit facility with MidCap Financial, which totaled $20.9 million as of March 31, 2026.

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 non-cash gains, increased by 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 (loss) income in accordance with U.S. GAAP as a measure of performance. See below for a reconciliation from net (loss) income, 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.
