Arvinas (ARVN) corrects CEO equity grant to 147,179 RSUs in Form 4/A

Rhea-AI Filing Summary

Teel Randy reported acquisition or exercise transactions in this Form 4 filing.

ARVINAS, INC. President and CEO Randy Teel reported an amended equity award, correcting the size of a previously disclosed grant of restricted stock units (RSUs) made on February 26, 2026.

The corrected grant covers 147,179 RSUs, each representing one share of common stock for no cash payment, under the company’s 2018 Stock Incentive Plan. The RSUs vest in four equal annual installments on February 12 of 2027, 2028, 2029 and 2030, contingent on his continued service. Following this correction, Teel is shown as beneficially owning 296,875 shares after the reported transaction.

The amendment fixes an earlier clerical error that had misstated the award as 147,791 RSUs and adjusts the reported post-transaction holdings to match the accurate grant amount.

1. The restricted stock units (each, an "RSU") were granted by the Issuer on February 26, 2026, pursuant to its 2018 Stock Incentive Plan (the "Plan"), and each RSU represents a contingent right to receive one share of the Issuer's common stock upon settlement for no consideration. The RSUs will vest over four years: one-quarter of the RSUs will vest on each of February 12, 2027, February 12, 2028, February 12, 2029 and February 12, 2030, subject to the Reporting Person's continued service with the Issuer on each such vesting date. This amendment is being filed to correct an inadvertent clerical error in reporting the number of RSUs awarded on February 26, 2026. The correct number of RSUs awarded was 147,179, not 147,791, as was originally reported on the Form 4 filed on March 2, 2026. Column 5, the amount of securities beneficially owned following reported transaction(s), has also been corrected accordingly.
