Coherent Corp.’s Chief Financial Officer, Sherri R. Luther, sold 2,000 shares in the open market on May 12, 2026 at $372.96 per share, for a total value of about $745.92K. A sale of this size by a CFO tends to draw attention because the CFO is closely involved in the company’s financial reporting, cash flow, and budgeting, and investors often watch their trading for signals about confidence and valuation. This transaction follows another sale by Luther on April 22, 2026, when she also sold 2,000 shares at $351.00 per share, showing a repeat pattern of similar-sized sales in recent weeks. While insider selling can happen for many non-business reasons—such as taxes, diversification, or pre-planned trading—it still matters as a data point because it reduces the insider’s exposure to the stock. Broader insider activity has also leaned toward selling recently. Over the last 30 days, another insider, Howard H. Xia, sold roughly $172.00K of shares on May 11, 2026. With multiple insiders selling close together, investors may want to monitor whether these sales continue and how they compare with any insider buying, which is generally viewed as a clearer sign of personal conviction.
