KIRA Β· ClearSign Technologies Corp had $5.2M of revenue in fiscal 2025, up 45.6% on the year before. Its operating margin was β127.5%, up 53.0Β pts: of every 100 in sales, about β127 is left after running the business.

How much cash comes in, and where does it go?
KIRA Β· Free cash flow was β$4.7M in fiscal 2025, β90.6% of revenue.
Cash from operations minus capital spending.
In plain words: Profit on paper is not the same as cash in the bank. Free cash flow is the cash left after paying to run and maintain the business: the money it can hand back to shareholders, save or invest.

KIRA Β· No open-market insider trades in the last 12 months.
Open-market purchases and sales by officers, directors and 10% owners, from Form 4 filings. βPlanβ marks trades under a pre-arranged Rule 10b5-1 plan.

Can it carry its debts, and how well does it use its money?
Cash, debt and the ratios that show how comfortably ClearSign Technologies Corp can carry it.
