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 Corporation reported a net loss of $2.19 million for the quarter ended March 31, 2026, slightly wider than the $2.08 million loss a year earlier. Revenue was $191 thousand, down from $401 thousand, as Q1 2025 included larger spare parts and engineering orders.
The company generated a gross loss of $393 thousand versus a prior gross profit, mainly due to a roughly $410 thousand warranty-related cost tied to process burners installed in 2025. Operating expenses fell to $1.89 million, driven by lower R&D and reduced legal spending after a prior special committee.
Cash and cash equivalents were $7.74 million with working capital of $6.61 million and no debt, and management believes this supports more than twelve months of operations. A 1-for-10 reverse stock split effective March 16, 2026 brought the share price back into compliance with Nasdaq’s minimum bid requirement.
ClearSign Technologies filed its Q3 2025 report, showing lower activity and continued operating losses. Revenue was $1.03 million with gross profit of $0.37 million, while the company posted a net loss of $1.43 million for the quarter. For the nine months, revenue was $1.56 million and net loss was $5.19 million.
Cash and cash equivalents were $10.49 million, and working capital totaled $8.17 million as of September 30, 2025. Contract liabilities rose to $1.15 million, reflecting customer prepayments on projects not yet completed. Stockholders’ equity was $9.08 million with no debt.
The company established a new at-the-market program of up to $10.39 million and noted Nasdaq’s extension to regain the $1.00 minimum bid price by March 30, 2026. Operating expenses increased year over year, driven mainly by non-cash RSU vesting tied to board departures and higher legal/audit costs, partially offset by prior China-related accruals not repeating.
