• Award: 274 stock units granted, acquisition price $0. Total reported value: $0 (units are derivative).
• Vesting: Per footnote, each stock unit equals one share upon vesting; units vest in full on August 15, 2027.

• Filing timeliness: Marked late — indicates the Form 4 was not filed within the usual 2-business-day window.

Context
This was an equity award (grant of stock units), not a market purchase or sale. Stock units are a form of deferred compensation: they do not increase immediately tradable share holdings until they vest and are converted into common stock. Late filings reduce the timeliness of public disclosure but do not by themselves indicate wrongdoing.
