QS Energy, Inc. develops Applied Oil Technology (AOT) for crude oil pipelines and remains in the development stage with no revenue for the three- and six-month periods ended June 30, 2026. The company reported a six‑month net loss of $2,944,000, a significant improvement from $11,813,000 a year earlier, driven mainly by lower stock-based compensation and reduced cash operating costs.
At June 30, 2026, cash was $120,000, stockholders’ deficit was $5,498,000, and total liabilities were $5,705,000. Management and the auditor highlight substantial doubt about the ability to continue as a going concern, given recurring losses, negative operating cash flow of $1,228,000, and heavy reliance on new financing.
Key past-due obligations include $3,167,000 owed to Temple University under license agreements and 46 convertible notes plus accrued interest totaling $1,201,000 in default, as well as $197,000 owed under a former officer’s separation agreement. The company continues to pursue collaboration and distribution arrangements with VIPS Petroleum and Laksel for potential AOT deployments but discloses that no purchase orders, contracts, or revenue have yet resulted.
QS Energy’s Q1 2026 report shows a much smaller loss but continued financial strain and no revenue. The company generated no revenue and reported a net loss of $781,000, compared with $9,674,000 a year earlier, mainly due to sharply lower non-cash stock-based compensation and reduced operating expenses.
Cash was only $33,000 at March 31, 2026, after using $468,000 in operating cash flow, partly offset by $495,000 of warrant exercise proceeds. The company has a stockholders’ deficit of $5,789,000, past-due notes and obligations exceeding $1,209,000 plus $3,167,000 owed to Temple University, and its auditors and management highlight substantial doubt about its ability to continue as a going concern while commercialization efforts for its AOT technology have not yet produced contracts or revenue.
QS Energy filed its Q3 2025 10‑Q, reporting continued losses and tight liquidity. The company posted a net loss of $1,964,000 for the quarter and $13,777,000 for the nine months ended September 30, 2025, with no revenues.
Cash was $49,000 as of September 30, 2025, and management stated there is “substantial doubt” about the ability to continue as a going concern. Stockholders’ deficit was $5,446,000. Operating expenses were $12,050,000 and research and development was $1,395,000 for the nine‑month period.
Current liabilities totaled $5,550,000, including accounts payable under Temple University license agreements of $3,167,000 and convertible notes payable, net, of $1,294,000. The company disclosed 42 notes and accrued interest aggregating $1,070,000 past due. An amendment confirmed $3,167,000 owed to Temple due by October 11, 2025, which remained unpaid as of this filing.
QS Energy increased its share count through conversions and equity-based awards, with 529,194,266 shares outstanding as of September 30, 2025, and 537,448,950 as of November 7, 2025.
