Insights

Financial Analyst

TL;DR: Insider proposes sale of 11,612 COHR shares (~$1.23M); recent 10b5-1 activity shows prior systematic sales.

The notice documents a planned sale executed through Morgan Stanley for 11,612 common shares valued at $1,234,820.08 with an expected trade date of 09/16/2025. Acquisition details show a mix of option exercise (6,154 shares, cash-paid) and RSUs (5,458 shares). Recent 10b5-1 sales in July–August 2025 totaled 8,849 shares with reported gross proceeds shown per trade. From a trading-impact perspective, the filing is routine disclosure of insider liquidity rather than new operational or financial information about the issuer.

Corporate Governance Expert

TL;DR: Filing appears procedurally compliant; disclosures indicate reliance on trading plan mechanisms and standard insider representation.

The form includes broker details and the seller's representation about absence of undisclosed material information, consistent with Rule 144 requirements. The presence of prior 10b5-1 sales and the mix of option exercise plus RSUs are typical of executive vesting and planned dispositions. No information in the filing indicates material corporate events or governance changes beyond ordinary insider selling activity.
