Insights

Insider transactions analyst

Officer purchased 7,500 OBK shares at ~$34.26.

An executive insider bought shares on 10/27/2025 via two open-market purchases totaling 7,500 shares at weighted average prices of $34.25 and $34.27. The filing notes execution across narrow price ranges, consistent with standard market activity.

Post-transaction holdings are diversified by registration: 54,882 shares direct, 2,500 via an IRA, and 14,589 in an issuer retirement plan. Insider buying can be viewed as aligned interest, but the filing does not state strategic rationale or future intentions.

Any market impact depends on broader trading and future disclosures; the filing provides no timing beyond 10/27/2025 and no cash-flow implications for the company.
