ClearSign Combustion ( (CLIR) ) has provided an announcement.
On April 9, 2026, ClearSign reported record fourth-quarter 2025 revenue of $3.7 million and full-year revenue of $5.2 million, a 44% annual increase, highlighting growing industry recognition and a stronger order backlog driven by its flexible-fuel, hydrogen-capable ClearSign Core-2 burner technology. Operationally, the company secured major engineering orders for dozens of process burner heaters from U.S. refiners, logged successful sub-5 ppm emissions tests with the U.S. Department of Energy, booked additional low-emission flare and hydrogen-capable burner testing work, delivered new M-series burners to gas processing facilities, and closed 2025 with $9.2 million in cash and 5,328,730 post–reverse split shares outstanding.
The most recent analyst rating on (CLIR) stock is a Hold with a $6.00 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 back primarily by weak financial performance (large losses and ongoing cash burn despite improving revenue). Offsetting this are positive technical signals and a constructive earnings-call backdrop featuring strong year-over-year growth and an expanding backlog/pipeline, though valuation support is limited due to negative earnings and no dividend.
