Key Details

• Filing date: Feb 3, 2026; Period of report: Jan 28, 2026. Transactions span Jan 28–Feb 2, 2026.
• Total shares disposed: 17,625; total reported proceeds ≈ $254,323.
• Shares owned after the reported transactions: not specified in the provided filing excerpt.
• Footnotes: some sales were made pursuant to a pre-established Rule 10b5-1 trading plan; other disposals were securities withheld to satisfy tax obligations incident to vesting (Rule 16b-3(e)).
• No indication in the provided data that the filing is late.

Context

• The mix of open-market sales under a 10b5-1 plan and securities withheld for taxes suggests routine insider activity (pre-arranged sales and tax-related withholding) rather than an unscheduled disposition.
• For retail investors: outright purchases generally carry more informational weight than routine sales or tax-withholdings. These transactions are informative about share movement but do not, by themselves, indicate management’s current view of the company.
