• Q1 Net Loss Widens Significantly

  Arq, Inc. reported a net loss of $0.842 million for Q1 2026, a substantial increase from a net income of $0.203 million in Q1 2025, resulting in diluted EPS of ($0.02).

• GAC Production Halted for FY2026 Due to Design Flaws

  The company decided in March 2026 to pause Granular Activated Carbon (GAC) production and idle its Corbin Facility for the entire fiscal year 2026, citing design flaws in the GAC facility and thermal oxidizer limitations.

• Revenue Exceeds Estimates Amid Operational Challenges

  Revenue increased by 7% to $29.053 million for Q1 2026, surpassing analyst estimates of $27.78 million, primarily driven by higher sales volumes of AC products to the power-generation market.

• Debt Covenant Waivers Secured for CTB Loan

  Arq, Inc. entered into an amendment to its CTB Loan on March 5, 2026, which waived certain financial covenants for fiscal year 2025 and suspended testing for fiscal year 2026, requiring increased deposits as a condition.

Arq, Inc.'s Q1 2026 results reveal a significant widening of its net loss to $0.842 million, despite a 7% increase in revenue to $29.053 million, which exceeded analyst estimates. The most critical development is the decision to pause Granular Activated Carbon (GAC) production for the entirety of fiscal year 2026 and idle the Corbin Facility due to persistent design flaws and thermal oxidizer limitations at the Red River Plant. This operational setback is a major blow to the company's growth strategy in advanced purification technologies and is compounded by ongoing litigation with the original design firm. Furthermore, the company secured a waiver for certain financial covenants on its CTB Loan for FY2025 and a suspension of testing for FY2026, requiring increased deposits. This indicates underlying financial stress and reliance on lender accommodation, despite management's assertion of sufficient liquidity for the next 12 months. While cash flow from operations improved significantly, the substantial operational challenges and financial covenant issues present a negative outlook for investors.
