Key Details

• Transaction date: 2026-01-23 (Form filed 2026-01-27)
• Disposition to issuer (code D): 1,759 shares @ $0.00 — forfeiture of part of a previously reported restricted stock award (footnote F1)
• Tax withholding (code F): 149 shares @ $59.69 — shares withheld by issuer to satisfy tax liability totaling $8,894 (footnote F2)
• Shares owned after transaction: not specified in the summary provided in this filing
• These were not open-market sales; they reflect forfeiture and tax withholding rather than a cash sale

Context

• Forfeitures and issuer tax-withholdings are administrative actions tied to equity awards and typically do not indicate a trading decision or immediate market sentiment by the insider.
• Footnotes clarify the forfeiture was from a prior restricted stock award and that the 149 shares were withheld to meet tax obligations upon vesting.
