Insights

Corporate Governance Expert

TL;DR Insider sale of 2,000 shares executed under a 10b5-1 plan reduces direct holdings to 23,836 shares; procedural disclosure appears complete.

The sale recorded on 08/13/2025 is explicitly tied to a Rule 10b5-1 plan adopted on November 21, 2024, which mitigates concerns about opportunistic timing. The director remains a holder with 23,836 shares, and the Form 4 was filed by one reporting person with a Power of Attorney signature. From a governance perspective, use of a pre-established plan and timely Form 4 filing align with standard compliance practices. The filing contains no derivatives or other transactions to suggest broader portfolio changes.

Securities Analyst

TL;DR Director executed a routine, pre-planned sale of 2,000 COHR shares; transaction size is small relative to typical institutional holdings.

The reported disposition used transaction code S at a price of $122.23, leaving the reporting person with 23,836 shares. The explicit mention of a 10b5-1 plan indicates the sale was prearranged rather than opportunistic. No information on total outstanding shares or percentage ownership is provided, so the market impact or change in insider alignment cannot be quantified from this filing alone.
