What this company does
Written from the business description in Zenas BioPharma, Inc.'s annual report to the U.S. Securities and Exchange Commission, filed 16 March 2026. Every sentence was checked against that document before publication.
Growth
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.
Profitability
Not applicable: equity was zero or negative in this period, so return on equity has no meaning.
Each USD of equity lost 136 cents this year.
The 3-year record
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.
