On June 3, COHERENT fell 3.22% in after-hours trading, trading at $406.0 USD/share, with trading volume of approximately $44.33 million. The decline comes as profit-taking pressure emerged following a series of sharp gains driven by major catalysts.

On the news front, the stock had previously surged over 17% on June 2 to $426.89, reaching a 52-week high with an intraday peak of $433.69, fueled by NVIDIA's announcement of a $2 billion strategic investment in Coherent for photonic technology R&D and U.S. domestic manufacturing expansion. The two companies also signed a multi-year strategic agreement to secure key capacity in light sources, optical components, and silicon photonics. Additionally, the broader optical communications sector experienced a full-scale rally, with Marvell Technology surging over 32% and Corning gaining over 10% in the same session.

Fundamentally, the NVIDIA strategic agreement remains in execution, with 1.6T optical module demand continuing to surge. Coherent has raised its small form-factor pluggable optical module shipment target to 5 million units. However, after the rapid consecutive price appreciation, short-term profit-taking pressure led to the after-hours pullback.
