Coherent Corp recorded an insider sale on March 9, 2026, when director Stephen A. Skaggs sold 3,523 shares of the company's common stock, generating approximately $856,550 in proceeds. The shares were transacted at a weighted average price of $243.1309, with individual trades executed between $237.90 and $250.00.
The disposition was carried out under a Rule 10b5-1 trading arrangement that Skaggs established on December 3, 2025. After the March 9 transaction, Skaggs's direct holdings in Coherent total 16,864 shares.
Market performance since the sale has been notable. The stock is trading at $251.41, representing a 278% gain over the last 12 months. Independent analysis cited by InvestingPro indicates that, based on Fair Value metrics, Coherent's shares currently appear overvalued.
Beyond insider activity, Coherent has expanded its product portfolio with announcements targeting optical transmission and AI data-center cooling and connectivity. The company introduced single- and dual-chip uncooled 980nm micro-pump lasers intended for coherent transmission systems, with published capability of delivering up to 700mW per fiber of output.
In thermal management for AI accelerators, Coherent launched the Thermadite 800 Liquid Cold Plates, which the company says provide thermal conductivity markedly higher than copper. On the connectivity front, Coherent unveiled the CHR1074, a 224Gbps quad-channel transimpedance amplifier designed for 800G and 1.6T optical transceivers, and described as employing a fast-settling architecture to bolster performance in AI and cloud infrastructure applications.
In a separate corporate development, S&P Dow Jones Indices has announced that Coherent will be added to the S&P 500 index, with the change set to take effect soon. The timing of the index inclusion was disclosed by S&P Dow Jones Indices.
Industry commentary referenced in recent coverage notes that Bank of America has a constructive view on optical networking stocks, pointing to strong demand and constrained supply across the sector. That outlook did not single out Coherent in the bank's remarks.
Taken together, the insider sale, the string of product launches aimed at optical transmission and AI infrastructure, and the impending S&P 500 inclusion frame a period of heightened activity for Coherent. At the same time, third-party valuation indicators cited by InvestingPro suggest investors may want to weigh current market multiples against Fair Value assessments.
