Absci (ABSI) CFO/CBO Zachariah Jonasson Receives RSU & Option Awards

What Happened

Zachariah Jonasson, Absci's Chief Financial Officer and Chief Business Officer, was granted equity on March 2, 2026: 135,400 restricted stock units (RSUs) and a derivative option covering 534,400 shares (total 669,800 shares). Both awards are reported at $0.00 (no cash purchase). On March 3, 2026, 10,848 shares were withheld at $2.80/share to satisfy tax withholding obligations, totaling $30,374. This filing is an amendment to correct the option expiration date (now March 1, 2036).

Context

These were grants/awards (not open-market purchases or exercises followed by sales). The option grant is a derivative grant that will vest over time — it was not exercised or sold. Tax-withholding by the company is a routine administrative action and does not indicate a voluntary sale by the insider.
