Key Details

• Transaction date: 2026-05-12 (Form 4 filed 2026-05-13) — appears timely, not a late filing.
• Security and amount: 28,509 restricted stock units (RSUs) granted.
• Reported price/value: $0 per unit; total reported acquisition value $0 (typical for RSU grants).
• Vesting (per footnote F1): grant includes RSUs from (i) the annual long-term incentive program (vesting in three equal tranches beginning March 1, 2027) and (ii) a one‑time long-term incentive award (vesting in three equal tranches beginning May 18, 2027). Each vested RSU settles into one share.
• Shares owned after transaction: not specified in the provided filing.
• No 10b5-1 plan, tax withholding sale, or other special codes noted in the details provided.

Context
This was a compensation award (RSUs), not an open‑market buy or sale. RSU grants are common long-term incentive compensation and only convert into actual shares as they vest over time, so they are not an immediate market purchase signal. Retail investors should note the multi-tranche vesting schedule — future vesting events could lead to issuances of shares or secondary sales by the insider when those units vest.
