System1, Inc. SST
What this company does
Written from the business description in System1, Inc.'s annual report to the U.S. Securities and Exchange Commission, filed 11 March 2026. Every sentence was checked against that document before publication.
Compound annual rates per period — left blank where that exact year isn't on file, the series crosses a loss, or (per-share rows) a split falls inside the window.
Each USD of equity lost 118 cents this year.
EPS, diluted, dividend per share and shares outstanding are shown without shading, and a vertical line marks the year the share count changed — the series crosses a large, unexplained change in share count, so the years on either side are not on a comparable scale.
