Achieved 8^th straight quarter of double-digit YoY ASP growth, strong gross margins of 36.4%, 4^th consecutive quarter of positive Adjusted EBITDA and positive net income for the quarter

Signed second largest PAC contract in Arq's history, evidencing sustainability and value of foundational business

Updating timing for first commercial GAC production at Red River to end of Q2 or early Q3 2025

GREENWOOD VILLAGE, Colo., May 07, 2025 (GLOBE NEWSWIRE) -- Arq, Inc. (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 ended March 31, 2025.

Financial Highlights

Generated revenue of $27.2 million in Q1 2025, up 25% over the prior year period, driven largely by higher average sales price ("ASP"), positive changes in product mix and higher volumes sold
Increased ASP in Q1 2025 by approximately 13% over the prior year period, reflecting the 8^th consecutive quarter of double-digit YoY percentage growth in ASP
All powder activated carbon ("PAC") contracts are now net cash producers following the successful resolution of all negative margin agreements as of December 31, 2024
Achieved gross margin of 36.4% in Q1 2025, versus 36.9% reported in the prior year period, driven by improved pricing and favorable customer mix, offset by start-up costs associated with the granular activated carbon ("GAC") line in Q1 2025 and a one-time accounting adjustment in Q1 2024
Reported Net income of $0.2 million in Q1 2025, reflecting a significant improvement over the prior year period Net loss of ($3.4) million
Adjusted EBITDA⁽¹⁾ of $4.1 million in Q1 2025 versus Adjusted EBITDA loss of ($0.4) million in the prior year period, reflecting the 4^th consecutive quarter of positive Adjusted EBITDA
Exited Q1 2025 with cash and restricted cash of $14.8 million
Capital expenditures forecast for full year 2025 remain in line with previous guidance of $8 - $12 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. As of Q1 2025, the Company began adjusting for stock-based compensation in EBITDA calculation; 2024 figures shown have been adjusted consistently.

Recent Business Highlights

Entered into a life-of-asset PAC contract with an existing customer in April 2025, representing the second largest dollar value contract in Arq's history
Appointed 35-year finance veteran Jay Voncannon as Chief Financial Officer. Mr. Voncannon has a strong track record as a proven financial leader and previously served as CFO of Coorstek, a multi-billion dollar privately held global manufacturer of advanced engineered ceramic products; and before that as a finance executive at Koch Industries
Completed mechanical completion of GAC Facility construction in January 2025. Small non-commercial scale volumes of GAC have been produced at Red River, however, not yet at the consistency necessary for commercial scale production. The Company is working through final technical testing related to the product binding and shaping processes and now anticipates first commercial production by the end of Q2 or early in Q3 2025. No material increase in the remaining portion of GAC Facility capital expenditures is anticipated as a result of this updated timeline
Maintaining guidance of a 3 - 6 month ramp-up phase to reach 25-million-pound nameplate capacity at Red River after first commercial production
The Company remains confident in its ability to successfully contract the remaining volumes at attractive pricing once the GAC Facility is fully operational
Arq's position as a fully vertically integrated domestic US supplier of activated carbon remains a unique point of differentiation within the industry and as a result any international tariffs are expected to have a neutral to positive impact on operations

"Our first quarter results demonstrate that the PAC business transformation is ongoing and sustainable," said Bob Rasmus, CEO of Arq. "With our fourth consecutive quarter of positive Adjusted EBITDA and the recent signing of the second largest contract in company history, we have established a robust foundation capable of delivering double-digit millions in annual Adjusted EBITDA. This provides us with the stable platform needed to pursue our exciting growth opportunities in GAC and beyond. To this end, we're thrilled to welcome Jay Voncannon as our new Chief Financial Officer, whose extensive experience in scaling businesses and driving profitability improvements will be invaluable as we enter our next phase of growth."

"As the only domestic producer with a fully vertically integrated supply chain, we are uniquely positioned in the current market environment and believe we have a distinct advantage versus many of our peers who source feedstock internationally," continued Mr. Rasmus. "Strong customer demand persists across our end markets, and we continue to see opportunities to enhance profitability through customer diversification and operational efficiency improvements."

"While we've made significant progress commissioning our GAC facility at Red River, we continue to work through the final commissioning process fine tuning and testing related to product binding and shaping," added Mr. Rasmus. "While we have produced small, non-commercial volumes of GAC, we have yet to achieve the consistency needed for commercial-scale production. Given these challenges, we now expect to achieve commercial production by the end of the second quarter or early third quarter. While this timeline represents a delay from our previous guidance, I remain fully confident in our technology and our team's ability to execute. Fundamentally, this is a decades-long opportunity, and we're committed to getting it right."

First Quarter 2025 Results

Revenue totaled $27.2 million for the first quarter of 2025, reflecting an increase of 25% compared to $21.7 million in the prior year period. The increase was driven predominantly by higher ASP, positive changes in product mix and volumes. ASP for the first quarter of 2025 was up approximately 13% compared to prior year period, marking the 8^th consecutive quarter of double-digit year-over-year percentage growth in ASP.

Costs of revenue totaled $17.3 million for the first quarter of 2025, an increase of approximately 26% compared to $13.7 million in the prior year period, principally driven by an increase in volumes and associated revenue as well as start-up costs associated with the GAC line at Red River.

Gross margin was 36.4% for the first quarter of 2025, compared to 36.9% in the prior year period. Gross margin remained flat, as higher pricing and favorable customer mix was offset by start-up costs associated with the GAC line in Q1 2025 and a one-time accounting adjustment in Q1 2024.

Selling, general and administrative expenses totaled $6.1 million for the first quarter of 2025, compared to $7.7 million in the prior year period. The reduction of approximately $1.6 million, or 21%, was primarily driven by lower payroll and benefits and G&A expenses. A portion of this decrease reflects the capitalization of payroll and benefits associated with our Corbin facility, which became operational in January 2025.

Research and development costs totaled $0.9 million for the first quarter of 2025, compared to $1.6 million in the prior year period. This reduction was primarily due to the Company performing product qualification testing in the prior year period with potential lead-adopters as part of its ongoing GAC contracting process.

Operating income was $0.7 million for the first quarter of 2025, compared to an operating loss of ($3.0) million in the prior year period. The improvement was mainly driven by the factors referenced above.

Net income was $0.2 million in the first quarter of 2025, compared to a net loss of ($3.4) million in the prior year period.

Adjusted EBITDA was $4.1 million for the first quarter of 2025, compared to Adjusted EBITDA loss of ($0.4) million in the prior year period, reflecting the 4^th consecutive quarter of positive Adjusted EBITDA. The increase over the prior year period was primarily driven by higher revenue 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

Capex for 2025 remains in line with previous guidance at $8 - $12 million. Capex totaled $3.7 million for the three months ended March 31, 2025, in line with management expectations.

Cash as of March 31, 2025, including $8.5 million of restricted cash, totaled $14.8 million, compared to $22.2 million as of December 31, 2024. The decrease was largely caused by capex relating to the Red River expansion, trade accounts payable, as well as build-up of inventory and spare parts at Corbin.

Total debt, inclusive of financing leases, as of March 31, 2025, totaled $26.8 million compared to $24.8 million as of December 31, 2024. The increase was driven by an increase in the outstanding principal balance of the Company's revolving credit facility.

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 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 income (loss), our most directly comparable as-reported financial measure calculated in accordance with U.S. GAAP, to EBITDA (loss) and Adjusted EBITDA (loss).
