ClearSign Technologies Corporation — FY2023 Form 10-K
Reporting period: Fiscal year ended December 31, 2023; comparisons are with FY2022.

- FY2023 revenue rose 542.6%, driven mainly by process-burner shipments and customer performance tests. Fourth-quarter revenue was $1.274 million, including a shipment for one of two heaters under a California refinery order.
- Gross profit increased by $0.701 million; management attributed the improvement to higher product shipments and testing. Net loss narrowed by $0.564 million, despite higher operating expenses, partly because of higher gross profit and other income.
- Other income was $0.787 million, including $0.324 million of interest income and $0.255 million of government assistance. The filing reports $0.203 million of other income, net, and $0.005 million of gains from asset sales.
- Total assets were $7.620 million and total liabilities were $2.428 million at December 31, 2023. The company reported no contractual debt obligations; lease liabilities totaled $0.243 million. Contract liabilities were $1.116 million, mostly customer payments received ahead of future project work.
- Investing activities provided $2.490 million, primarily from net redemptions of short-term U.S. Treasury investments. Financing activities used $0.015 million; no common-stock proceeds were raised in 2023.
Business developments and changes
- ClearSign reported commercial deployments of process burners, boiler burners, and enclosed flares. In 2023, it completed contractual obligations for one heater in a 13-burner order; the installed burners met the customer’s NOx permit level, confirmed by a third-party inspector. Completion of work on the second heater was expected in 2024.
- Two boiler-burner orders were received in 2023. Third-party testing validated the 5-ppm emissions result for one; the other had not been installed due to customer construction delays.
- On February 2, 2024, SCAQMD approved new Best Available Control Technology performance guidelines for single- and multi-burner configurations after assessing ClearSign technology at customer sites. The filing says this is not an endorsement but establishes benchmarks the company believes favor its products.
- On February 21, 2024, the company announced that California Boiler received a letter of intent for four ClearSign Core boilers and placed an order for the first burner.
- Revenue remains concentrated in project activity and milestone-based contracts; customers’ on-site delays and subcontractor performance can defer delivery, milestones, and revenue recognition.
Outlook, risks, and unusual items
- Management expects operating losses and negative cash flows for the foreseeable future. The company states that it did not have sufficient working capital to fund operating expenses for the next 12 months as of the report, and that substantial doubt about its ability to continue as a going concern had not been alleviated. The auditor’s report also highlights substantial doubt. The statements do not include adjustments that might result if the company cannot continue as a going concern.
- Management contemplated a public offering under its Form S-3 shelf registration statement in April 2024 and expected that, if completed, it could provide at least 12 months of additional funding. This was a plan, not assured financing. The ATM sales program was suspended on March 18, 2024; sales cannot resume unless a new prospectus supplement is filed.
- Key risks include limited cash and recurring losses; dependence on new financing and market acceptance; slow adoption by risk-averse customers; competition; reliance on subcontractors and partners, including Zeeco; regulatory changes and permitting; supply disruptions; intellectual-property protection; China-related risks; and potential product liability.
- Nasdaq notified the company in November 2023 that it was out of compliance with board-independence and audit-committee composition requirements. The disclosed cure period runs to the earlier of the next annual meeting or November 11, 2024, subject to the stated timing conditions. Failure to regain compliance could result in delisting.
- Unusual FY2023 items included an $81,000 impairment of retired demonstration burners, $14,000 of intangible-asset impairment, and noncash compensation expenses associated with executive and director equity awards. The company also received approximately $1.6 million in a two-year DOE Phase 2 award for hydrogen-burner development; recognized DOE reimbursements were $191,000 in 2023.
- The company is developing a process burner designed to use 100% hydrogen, with a target project end date in 2025. It also continues to seek first adopters for its ClearSign Eye flame sensor. No quantified revenue, earnings, or cash-flow guidance is provided.
Most important facts for investors to verify
- Whether the contemplated public offering was completed, its proceeds and dilution, and the company’s updated cash runway and going-concern assessment.
- Whether remaining refinery-order work and pending boiler and flare projects were installed, accepted, and converted into recognized revenue and cash collections.
- Whether the four-boiler letter of intent progressed to additional purchase orders and deliveries.
- Whether ClearSign regained Nasdaq board and audit-committee compliance within the cure period.
- Whether strategic-partner sales terms, particularly with Zeeco, were finalized and whether partnerships support repeatable sales at sustainable margins.
- Whether customer deployments and regulatory benchmarks translate into broader adoption, and whether hydrogen and sensor products reach commercial milestones within expected timelines.
