Kosacz Barbara 4

What Happened

• Barbara Kosacz, a director of XOMA Royalty Corp (XOMA), was granted 3,586 restricted stock units (RSUs) on May 21, 2026. The grant is reported as an award (transaction code A) at $0.00 per unit, so there was no cash exchanged at grant.
• These RSUs represent the right to receive one share of common stock per RSU at settlement; the filing does not show immediate share ownership or any sale/purchase in the open market.

Key Details

• Transaction date: 2026-05-21; Filing date (Form 4): 2026-05-26 (appears to be filed late).
• Grant: 3,586 RSUs at $0.00; reported acquisition value $0 at grant.
• Shares owned after transaction: Not specified in the filing.
• Footnote (F1): RSUs vest in equal monthly installments over 12 months from the grant date, subject to continued service.
• Remarks: Exhibit 24 (Power of Attorney) included with the filing.

Context

• RSUs are compensation awards that convert to actual shares only upon vesting; this grant is compensation for service rather than a market purchase or sale and does not by itself signal immediate buying or selling.
• Because the award vests over the next 12 months, any future share deliveries (and potential sales) would depend on vesting and any subsequent transactions, which would be reported separately.
