Key Details

Transaction date and price: 2026-01-27 — 42,099 shares withheld at $17.98 per share (total $756,940).
Filing date: Form 4 filed 2026-01-29 (appears to be filed within the usual 2-business-day window).
Shares owned after transaction: Not specified in the filing.
Footnote: Shares were withheld to satisfy tax withholding on RSU settlement. Retained securities remain subject to a 180-day IPO lock-up that began with the final prospectus dated Oct 26, 2025 (lock-up ends in late April 2026), per the footnote.

Context

This was a routine tax-withholding/settlement of equity awards (cashless in effect) rather than an insider selling shares on the open market. Such withholdings are standard when RSUs vest and do not necessarily indicate a change in insider sentiment. The retained shares continue to be subject to the issuer’s IPO lock-up restrictions.
