Rapid Micro Biosystems Director Bika Dafni Receives RSU & Option Grant
What Happened
Bika Dafni, a director of Rapid Micro Biosystems, received equity awards on 2026-05-21: 19,300 restricted stock units (RSUs) and a derivative grant for 38,700 shares (an option-like award). Both items were reported at $0.00 per share (compensatory grants), so no cash changed hands in the filing.
Key Details
- Transaction date: 2026-05-21; Form 4 filed: 2026-05-26 (filed on the SEC deadline given the Memorial Day holiday).
- Grants: 19,300 RSUs (acquired, $0.00) and 38,700 derivative units (acquired, $0.00). Total granted = 58,000 share-equivalents.
- Vesting: Both awards vest in full on the earlier of (i) the first anniversary of the grant date or (ii) the day before the next annual meeting of stockholders, subject to continuous service (per footnotes F1 and F2). The derivative grant becomes exercisable on that same schedule.
- Shares owned after the transaction: not disclosed in this filing.
- No 10b5-1 plan, tax-withholding sale, or late-filing indication is noted in the report.
Context
RSUs convert to shares upon vesting and the derivative award becomes exercisable at vesting; neither represents an immediate open-market purchase or sale. These are standard compensatory grants to a director and should be viewed as such—informative about company compensation and potential future dilution, but not a direct buy/sell signal.
