ClearSign Technologies Corp 8-K

ClearSign Technologies Corporation (CLIR) filed a Form 8-K reporting a Certificate of Amendment filed with Delaware on March 6, 2026 to implement a 1-for-10 reverse stock split. The Reverse Stock Split will become effective at 12:01 a.m. Eastern Time on March 16, 2026, and the company expects its common stock to trade on a post-split basis on the opening of trading on March 16, 2026 under CUSIP 185064201.

• No fractional shares will remain outstanding; holders of fractional shares will receive shares rounded up to the next whole share at the participant level with the Depository Trust Company (DTC).

Why It Matters
A reverse split reduces the number of outstanding shares and increases the per-share price proportionally but does not change the company’s market value or individual ownership percentages (aside from effects of fractional-share handling). Investors should note the effective date (March 16, 2026), the CUSIP change for post-split trading, and that warrants and equity awards will be adjusted, which affects strike/exercise amounts. Check brokerage accounts after market open on March 16 for updated share counts and prices and review your warrant/equity award notices for adjusted terms.
