Insights

Equity Compensation & Insider Activity Analyst

Routine vesting and PSU settlement; neutral signal.

The filing shows standard equity compensation events: a time-based vest added 8,559 shares and a PSU grant settled for 5,115 shares after an 82% payout. Both were recorded at $0, consistent with non-cash share issuance from awards.

The PSU program tied to three-year relative TSR indicates performance alignment, but this disclosure alone doesn’t change business fundamentals. The officer’s holdings rose to 161,207 shares directly; market impact depends on any future sales, which are not indicated here.
