Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 13% in Q2 and 18% YTD compared to 2024. This was driven by higher sales volumes (due to increased coal-fired power generation from higher natural gas prices) and improved pricing.
- Profitability Improvement: Net loss narrowed significantly on a YTD basis ($1.9M loss vs. $5.4M loss in 2024). Adjusted EBITDA turned positive and grew substantially.
- Expense Fluctuations:
- Selling, General & Administrative (SG&A): Decreased 16% in Q2 and 18% YTD, primarily due to payroll capitalization at the Corbin Facility and reduced incentive compensation.
- Research & Development (R&D): Increased significantly (190% in Q2, 40% YTD) due to feedstock consumption during pre-production testing of the new Granular Activated Carbon (GAC) Facility.
- Depreciation: Increased due to decreased absorption in inventory.
- Liquidity: Cash and restricted cash decreased by $6.8 million YTD, primarily due to working capital increases (inventory and receivables) and capital expenditures, partially offset by net borrowings.
Outlook, Commentary, and Risks
- Red River Project: Commissioning of the Red River Plant expansion was completed in August 2025. The company expects to use "Arq Powder" as feedstock for high-quality GAC products in the second half of 2025.
- Corbin Facility: Operations were reduced in April 2025 following a review of inventory requirements. Normal operations are planned to resume in the second half of Q3 2025.
- Regulatory Drivers: The EPA's PFAS National Primary Drinking Water Regulation is expected to drive material increases in GAC demand for water purification, with compliance dates potentially extending to 2031.
- Liquidity Position: Management expects cash on hand and borrowing availability under the Revolving Credit Facility to fund operations for the next 12 months.
- Legal Proceedings: The company commenced legal action in February 2025 against the design firm for the GAC Facility, alleging negligence and breach of contract resulting in cost overruns and delays.
- Risks: Key risks include dependence on coal-fired power generation (affected by natural gas prices), execution risks in ramping up new GAC capacity, and potential impacts from tariffs or changes in environmental regulations.
Investor Verification Checklist
- Verify the timeline for full commercial production and nameplate capacity ramp-up at the Red River Plant.
- Monitor the status of the legal proceedings against the GAC Facility design firm and potential recovery of damages.
- Track the resumption of operations at the Corbin Facility and its impact on cost structures.
- Review the utilization of the $30.0 million Revolving Credit Facility and adherence to liquidity covenants (minimum $5.0 million liquidity requirement resets Dec 1, 2025).
- Assess the impact of natural gas price volatility on coal-fired power generation demand and subsequent product sales volumes.
