On the same date, 473 shares were disposed/withheld at $44.22 per share to cover tax liability (code F), totaling $20,916.

Key Details

Shares owned after transaction: not disclosed in this Form 4 filing.
Footnotes: PSUs were granted Jan 18, 2023; initial certification in Jan 2026 approved 80% of earned shares pending competitors’ audited 2025 results; final shares reflect all competitors’ reported 2025 audited results (footnote F1). F2 notes "equivalent shares" updated Nov 2025.
Filing timeliness: Form 4 filed March 17, 2026 for a March 13, 2026 transaction (filed within the normal two-business-day window).

Context

This was not an open-market purchase. The acquisition represents vested PSUs (compensation), while the 473-share disposition was a routine tax-withholding/cashless action to satisfy tax obligations — common when awards vest and not generally interpreted as a directional trading signal.

Footnotes (2)

[F1]The Company granted performance share units ("PSUs") to the reporting person on January 18, 2023. Vesting of the PSUs was based on three-year Company performance relative to select key competitors. Most of these competitors had not reported their 2025 audited financial results when the Company's compensation committee met in January 2026 to certify performance under the PSUs. As a result, the Company's compensation committee approved the issuance of 80% of the shares that the committee determined had been earned according to the information available to the committee at the time. As of March 13, 2026, all such competitors had reported their 2025 audited financial results. Shares of common stock reported hereunder represent shares finally determined to have been earned under the PSUs.
[F2]Equivalent shares as updated November 2025.
