ClearSign Combustion ( (CLIR) ) has provided an update.
On February 24, 2026, ClearSign Technologies held a corporate update call to discuss preliminary, unaudited financial results for the fourth quarter and full year ended December 31, 2025, alongside broader business developments, noting that its auditor had not yet reviewed the figures. Management highlighted that the fourth quarter of 2025 was a record revenue period, driven largely by a 26-burner order for a major Texas Gulf Coast petrochemical customer and supported by growth in flare systems, engineering services, installation work and spare parts, reinforcing the company’s strategy of diversifying revenue and deepening market penetration.
Executives pointed to a strong three-year track record of double-digit annual growth and a compound annual growth rate of about 141%, with full-year revenues up roughly 44% year-over-year, underpinned by rising demand across its burner and flare lines. They also emphasized the operational and strategic significance of the new Gen 2 ClearSign Core burner technology and successful comprehensive testing of a 100% hydrogen-capable burner for a global petrochemical client, which they believe is informing that customer’s long-term upgrade plans and could enhance ClearSign’s role in future fleet modernization and hydrogen-fuel adoption.
The most recent analyst rating on (CLIR) stock is a Buy with a $0.66 price target. To see the full list of analyst forecasts on ClearSign Combustion stock, see the CLIR Stock Forecast page.
Spark’s Take on CLIR Stock
According to Spark, TipRanks’ AI Analyst, CLIR is a Neutral.
The score is held down primarily by weak financial performance (persistent losses, negative cash flow, and a recent TTM revenue decline) and bearish technicals (below key moving averages with negative MACD). Offsetting factors include improving operational signals from the earnings call (gross margin expansion and order flow) and a positive corporate event indicating a record preliminary Q4 revenue surge, supported by a low-debt balance sheet.
