Rhea-AI Summary

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.
