Arq, Inc. (ARQ) appointed Peter Owino as Chief Accounting Officer, effective September 1, 2026, and he will remain the company’s principal accounting officer.

As an inducement to join as an employee, Owino received 100,000 restricted stock awards granted outside Arq’s 2026 Omnibus Incentive Plan, vesting in three equal annual installments subject to continued service.

Net loss narrowed to $0.7 million (‑$0.02 per share) from $2.4 million (‑$0.06 per share) a year earlier. Adjusted EBITDA increased to $5.8 million, a 59% gain, marking the ninth consecutive quarter of positive Adjusted EBITDA, driven by pricing, volume growth and the core PAC business, with no drag from prior GAC production costs.
Arq reaffirmed full‑year 2026 guidance of $120–$125 million in revenue and $17–$20 million in Adjusted EBITDA. At June 30, 2026, total assets were $233.0 million, cash and restricted cash were $12.1 million (including $11.2 million restricted), and total debt was $30.7 million, mainly borrowings on a revolving credit facility. Capital expenditures were $1.2 million in the quarter, and net cash used in operating activities improved to $2.7 million for the first half of 2026.
Arq, Inc. amended the employment agreement of President and CEO Robert Rasmus, setting a defined term that expires on July 23, 2029, subject to earlier termination or resignation. As of the amendment effective date, his annual salary is set at $50,000, and he is no longer eligible for an annual bonus or participation in the company’s long-term incentive compensation plan, with certain business expenses reimbursable.
In connection with the amendment, the compensation committee approved equity awards under the 2026 Omnibus Incentive Plan: 600,000 time-based RSUs vesting 300,000 on the second anniversary of grant and 300,000 on the third, with acceleration upon a Change in Control or specified termination events; and 600,000 performance-based RSUs, vesting in three 200,000-unit tranches if the 30-Day VWAP reaches $3.00, $6.00, and $9.00 per share, respectively, before the third anniversary, with early-achieved tranches vesting no earlier than the first anniversary and subject to similar acceleration and dilution adjustments.
Arq and Mr. Rasmus also extended the performance period for 400,000 Inducement RSUs from July 17, 2026 to July 17, 2029.
Arq, Inc. reported that its previously announced leadership change has been formalized through a Separation Agreement with former Chief Accounting Officer Stacia Hansen.

Arq, Inc. reported first quarter 2026 revenue of $29.1 million, up about 7% from $27.2 million a year earlier, mainly from higher sales volumes. Gross margin declined to 34.2% from 36.4% as pricing pressure, an inventory revaluation charge and GAC carry-costs outweighed volume gains.
The company posted a net loss of $0.8 million, or $0.02 per diluted share, versus net income of $0.2 million in the prior-year period. Adjusted EBITDA was $2.7 million compared with $4.1 million, reflecting lower margins and the non-cash inventory revaluation. Arq ended the quarter with $15.9 million in cash and restricted cash, including $11.2 million restricted, and total debt of $30.2 million.
Management reaffirmed full-year 2026 guidance for revenue of $120–$125 million and Adjusted EBITDA of $17–$20 million. The ongoing GAC strategic optimization review is expected to yield a go-forward strategy by Q3 2026, while the PAC business and Corbin asphalt opportunities continue to progress.
Arq, Inc. detailed separation arrangements for former executives Jeremy “Deke” Williamson and Jay Voncannon. Effective April 29, 2026, Williamson will receive approximately $361,500, equal to twelve months of base salary, paid bi-weekly, plus accelerated vesting of 34,270 restricted shares and 49,736 performance share units, subject to a total shareholder return calculation within sixty days, and a lump-sum payment equal to twelve months of COBRA premiums. Voncannon will receive statutory COBRA benefits for eighteen months and accelerated vesting of 50,000 restricted shares. Both executives agreed to customary releases of claims under their Separation and General Release Agreements.
Arq, Inc. reported that it entered into a Ninth Amendment to its Tax Asset Protection Plan with Computershare Trust Company, N.A. as rights agent. The amendment updates the definition of the plan’s “Final Expiration Date.”
Under the Ninth Amendment, the Final Expiration Date will be the close of business on the earlier of December 31, 2027, or December 31, 2026 if stockholder approval has not been obtained before that date. The amendment and its terms are set out in full in Exhibit 4.1 to the report.
Arq, Inc. amended its revolving credit facility again on March 31, 2026, entering a fifth amendment to its Credit, Security and Guaranty Agreement with MidCap Funding IV Trust and other lenders. This amendment replaces the existing minimum liquidity covenant with a $2.5 million availability reserve requirement, which will rise to $5 million starting in January 2027.
The amendment also allows certain eligible equipment and defined Rolling Stock to be counted in the borrowing availability calculation and temporarily relaxes the definition of Eligible Accounts to permit higher single-customer concentration until August 2026. The full amendment text is referenced as Exhibit 10.1.
Arq, Inc. reported 2025 results showing strong revenue growth but a sharp swing to loss as it pauses its granular activated carbon (GAC) ramp. Revenue reached $120.3 million, up 10% from 2024, driven by record powdered activated carbon (PAC) volumes and pricing, but a non‑cash impairment of about $45 million tied to the Corbin facility pushed full‑year net loss to $52.6 million versus a $5.1 million loss a year earlier.
Gross margin fell to 27.9% from 36.2%, mainly from GAC start‑up costs, and Q4 margin dropped to 13.6%. Adjusted EBITDA improved to $13.2 million from $10.5 million as lower SG&A and PAC strength offset part of the GAC drag. The company is idling Corbin, conducting a comprehensive GAC optimization review, and does not expect GAC production in 2026.
Leadership changes include appointing Eric Robinson as VP Operations, eliminating the COO role, and reorganizing the finance team. For 2026, Arq guides to revenue of $120–125 million and Adjusted EBITDA of $17–20 million, assuming no GAC contribution. PAC ASP is expected at $0.88–0.91 per pound on 122–125 million pounds of volume, with additional chemicals contributing 13–15% of revenue.
Arq, Inc. entered into a fourth amendment to its Revolving Credit Agreement with MidCap Funding IV Trust and other lenders. This amendment extends earlier changes to how borrowing availability is calculated and temporarily adjusts the company’s minimum liquidity covenant.
Under the revised covenant, Arq must maintain at least $2.0 million of liquidity from December 10, 2025 through March 31, 2026, increasing to $5.0 million starting April 1, 2026 and at all times thereafter. The full legal terms are contained in Amendment No. 4, filed as an exhibit.
Arq, Inc. entered into a third amendment to its Revolving Credit Agreement with MidCap Funding IV Trust and related lenders. The amendment extends prior changes to how borrowing availability is calculated and temporarily relaxes the company’s minimum liquidity requirement.
Under the revised covenant, minimum liquidity is set at $2.0 million from December 10, 2025 through February 27, 2026, increasing to $5.0 million from February 28, 2026 and at all times thereafter. This adjustment provides Arq with near‑term liquidity flexibility while re-establishing a higher long‑term threshold.
Arq, Inc. reported that it entered into a second amendment to its existing Credit, Security and Guaranty Agreement with MidCap Funding IV Trust and the lenders party to that agreement. The amendment updates how borrowing availability is calculated under the revolving credit facility and revises the company’s minimum liquidity covenant.
Under the revised covenant, the minimum liquidity required from December 10, 2025 through January 30, 2026 is set at $2.0 million. Beginning January 31, 2026 and at all times thereafter, the minimum liquidity requirement increases to $5.0 million. The full text of the amendment is filed as an exhibit for reference.
