Advent Technologies Holdings, Inc. ADNH
What this company does
Written from the business description in Advent Technologies Holdings, Inc.'s annual report to the U.S. Securities and Exchange Commission, filed 6 June 2025. 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.
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.
