Absci (ABSI) CLO awarded RSUs and 356,300-share option in Form 4

Rhea-AI Filing Summary

Absci Corp Chief Legal Officer Shelby J. Walker reported equity awards and a related tax-withholding share disposition. On March 2, Walker received a grant of 90,300 shares of common stock as restricted stock units under Absci’s 2021 Stock Option and Incentive Plan, and a separate stock option covering 356,300 shares at an exercise price of $0.00 per share.

The RSUs and the option are scheduled to vest in three substantially equal annual installments beginning on March 1, 2027, subject to continued service. On March 3, 9,825 shares of common stock at $2.80 per share were withheld by Absci to cover tax obligations tied to RSU vesting, which the filing states was not a discretionary trade. After these transactions, Walker directly owned 139,775 shares of common stock.

Insights

Equity Compensation Analyst

Routine equity awards with tax withholding, no open-market trading.

Absci granted its Chief Legal Officer 90,300 restricted stock units and a 356,300-share stock option, both vesting over three years starting on March 1, 2027. These awards align the executive’s compensation with future company performance through time-based vesting.

The F-code transaction for 9,825 shares at $2.80 per share is explicitly described as shares withheld to satisfy tax obligations upon RSU vesting, not a discretionary sale. From an investor perspective, this is standard administrative activity and does not change the fundamental outlook.
