Clearsign Technologies Corp Financials

This page shows its income statement, balance sheet, cash flow statement, and key financial ratios.

Revenue gains have not yet overcome the overhead base, leaving cash burn driven by operations rather than investment.
From FY2023 to FY2025, revenue more than doubled, yet gross margin slipped from34.0% to27.2% , implying newer sales carried less gross profit per dollar. With FY2025 operating cash flow at-$4.7M and capex only$4K , the burn is tied to sustaining overhead rather than building assets, so growth has not yet altered the business's cost structure.
