Enrico Digirolomo, a director at Coherent Corp. (COHR), sold 3,911 shares in the open market on March 6, 2026 at $241.50 per share, for total proceeds of about $944,510. For retail investors, the key takeaway is the size of the sale: it’s a near-$1 million transaction by a board member, which can be notable because directors are expected to have a broad view of company strategy and oversight, even if they are not involved in day-to-day operations. This trade also matters in context of recent insider activity. Over the past 30 days, COHR has seen multiple sizeable insider sales, including Stephen A. Skaggs selling about $856,550 on March 9 and CTO Julie Sheridan Eng selling about $375,390 on March 10. Earlier, Eng also completed a large sale on March 2 worth roughly $813,650, indicating that selling has been clustered among senior leaders and board-level insiders in early March. Insider selling can happen for many personal reasons, such as taxes or diversification, but a concentrated run of sales is information investors often track because it reflects how several insiders are choosing to reduce exposure around the same period.
