Insights

TL;DR: Director's entire equity position was extinguished in a merger where shareholders received $1.95 cash plus a contingent value right per share.

The Form 4 reflects a corporate-action disposition, not a voluntary sale, consistent with the announced merger and tender offer by XOMA Royalty Corporation. The material terms cited—$1.95 cash per share plus one CVR per share—are the key economic outcomes for former equity holders. The cancellation and cash settlement of RSUs reduced potential future dilution and converted equity compensation into merger consideration.

TL;DR: Insider holdings were converted and cancelled under merger terms; disclosure aligns with Section 16 reporting requirements.

The filing documents appropriate Section 16 reporting following a change-in-control transaction. Use of Transaction Code U and the attorney-in-fact signature indicate administrative filing compliance. The complete vesting and cash settlement of RSUs is notable for disclosure of how incentive awards were treated at closing.
