Arq, Inc. (ARQ) appointed Peter Owino as Chief Accounting Officer, effective September 1, 2026, and he will remain the company’s principal accounting officer. Arq entered into an employment agreement providing a $350,000 annual base salary, eligibility for a short-term incentive bonus targeted at 55% of base salary, and a long-term incentive award targeted at 75% of base salary.

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. If terminated without Cause or he resigns for Good Reason, he is eligible for 12 months of base salary, bonus for the year of termination based on actual performance, accelerated vesting of time-based equity and performance share units (based on actual performance to the termination date), and a lump-sum payment equal to 12 months of COBRA premiums. The filing also discloses that a prior consulting agreement with Princeton Business Consulting for Owino’s interim role resulted in approximately $200,000 of payments and was terminated upon his appointment. A press release announcing his appointment and inducement awards was issued on August 28, 2026.

Arq, Inc. (ARQ) reported that its Chief Technology Officer, as the reporting person, received an equity compensation grant of 55,000 shares of Common Stock on August 14, 2026. These shares are in the form of restricted stock awards (RSAs) granted under Arq, Inc.'s 2026 Omnibus Incentive Plan, which stockholders approved on June 10, 2026.

The RSAs are scheduled to vest on August 31, 2028. Following this award, the reporting person's directly held Common Stock position increased to 506,648 shares. The transaction is characterized as a grant or award acquisition and carries no per-share purchase price.

Arq, Inc. reported stronger profitability for the quarter ended June 30, 2026. Revenue rose to $29.9 million, up 5% year over year, while cost of revenue declined about 4%, lifting gross margin to 38.5% from 33.3%.

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. reported modestly higher sales but remained unprofitable for the quarter and first half of 2026. For the three months ended June 30, 2026, revenue was $29.9 million versus $28.6 million a year earlier, while net loss narrowed to $0.7 million from $2.4 million. For the six months, revenue reached $58.9 million with a net loss of $1.9 million, improving from a $2.4 million loss in 2025.

Cost controls and mix helped margins: three‑month cost of revenue excluding depreciation fell to $18.4 million from $19.1 million, aided by idling the Corbin facility and lower sales of lower‑margin chemicals. Adjusted EBITDA rose to $5.8 million for the quarter and $8.6 million year‑to‑date. The company changed its turnaround accounting to a deferral method, increasing June 30, 2026 retained earnings by $1.6 million versus the prior method.

Liquidity is tight with $0.9 million of cash and $11.2 million of restricted cash against $30.7 million of debt, including $21.4 million drawn on a $30 million revolving facility. Arq has paused GAC production and expects no GAC output in 2026 or 2027 while an optimization and redesign review continues; litigation with the former GAC design firm is ongoing. Management expects existing cash and revolver availability to fund operations for the next 12 months.
