ClearSign Technologies Corp (CLIR): Shares Outstanding

Annual figures by period end, from SEC filings.

Stock splits: 1-for-10, first reflected in a filing dated 2026-03-31. Figures are as filed: per-share figures and share counts last reported before a split are on the old share basis, so changes and growth rates across a split are not shown. Splits are read from the filings' own restatements, so a share conversion in a merger or reorganization shows up the same way.

Restated years: each year's figure is from the latest filing that reports it. The company later restated the year ended 2020-12-31 (for example after a spin-off or a discontinued operation), while the year before it was last reported on the old basis. Changes across those points are marked n/c (not comparable), and growth rates are not computed across them.
