Insights

TL;DR Insider exercised vested options and sold shares under a 10b5-1 plan; direct holdings remain material.

The Form 4 reports option exercises of 22,000 and 7,500 shares at exercise prices of $12.03 and $12.48, respectively, with concurrent sales at $45.00 per share executed under a 10b5-1 plan adopted on 12/04/2024. The disclosure shows 69,425 shares held directly after the transactions and multiple blocks held indirectly via irrevocable and family trusts. This is a routine, preplanned liquidity event rather than an unplanned sale; it provides clear, itemized post-transaction ownership figures for investor review.

TL;DR Transactions were prearranged under a 10b5-1 plan and the filing confirms vesting status and trust-held indirect ownership.

The filing explicitly states the trades were effected pursuant to a Rule 10b5-1 trading plan adopted on December 4, 2024, and that the option shares were fully vested and exercisable when exercised. The Form 4 also discloses several sizable indirect holdings held in named irrevocable trusts and a family trust, with the specific share counts listed. From a governance standpoint, the filing meets Section 16 transparency requirements by documenting the plan, exercise prices, sale price, and post-transaction beneficial ownership.
