ClearSign Technologies Corporation (CLIR) reported second quarter 2026 results and operational progress. Revenue for the quarter was $560,000, up from $133,000 a year earlier, with a gross profit margin of 41%. The quarterly net loss narrowed by $373,000, driven largely by a $368,000 reduction in general and administrative expenses following lower legal costs.
Net cash used in operations was $1.2 million versus $511,000 in the prior-year quarter, and cash and cash equivalents totaled $9.9 million as of June 30, 2026. A subsequent private equity sale of 500,000 shares at $3.54 per share added about $1.7 million in net proceeds, giving a pro forma cash balance of roughly $11.6 million. Shares outstanding were 5,328,730 as of June 30 and 6.8 million as of August 8.
Operationally, ClearSign highlighted orders for six M1 midstream burners for top-tier West Texas operators, development of a licensing/royalty model with a heater manufacturer, progress on a 32-burner California refinery project and a 26-burner Gulf Coast petrochemical project, and growth of its flare line with full-system projects typically in the $750,000–$1.5 million range. A 36-burner Texas project is on hold pending customer financing. The board added former ExxonMobil global technology leader Larry Saddler.
ClearSign Technologies Corporation reported higher revenues but continued losses for the three and six months ended June 30, 2026. Quarterly revenue rose to $560 thousand from $133 thousand a year earlier, and six‑month revenue increased to $751 thousand from $534 thousand, driven by flare system deliveries, spare parts, CFD studies, and burner projects.
Despite this growth, the company recorded a net loss of $1.3 million for the quarter and $3.5 million year‑to‑date, modestly better than prior‑year losses. Year‑to‑date gross profit turned negative, mainly due to a large warranty accrual tied to 2025 burner installations. Cash and cash equivalents were $9.9 million with working capital of $8.8 million, supported by a June underwritten offering providing about $3.4 million in net proceeds and a July private placement adding approximately $1.75 million. Management states it expects to fund operations for over twelve months but continues to anticipate operating losses and reliance on equity financing.
ClearSign Technologies Corp filed an initial beneficial ownership report for Larry Michael Saddler, who is identified as a director of the company.

Under an offer letter consistent with ClearSign’s non-executive director compensation policy, Saddler will receive $60,000 in annual cash compensation, payable quarterly and optionally convertible into restricted stock units, plus $40,000 annually in non-statutory stock options granted quarterly, all under the Amended and Restated 2021 Equity Incentive Plan.
