On July 1, Coherent fell 5.13% in regular trading, trading at $370.98/share, with turnover of $147 million. The decline was driven by a broad selloff across the U.S. optical communications sector.

On the news front, the optical communications sector experienced collective weakness, with Corning falling over 9%, Marvell Technology down nearly 3%, and Lumentum dropping over 2%. Storage stocks also declined in tandem, with Micron Technology down 3% and SanDisk falling over 4%. As a core optical communications name, Coherent tracked the broader sector pullback. Notably, Coherent's fundamentals showed no apparent negative catalysts — the company recently secured a $50 million CHIPS Act subsidy in mid-June earmarked for expansion of its 6-inch indium phosphide production line at its Sherman, Texas facility. The current decline appears to reflect broader industry sentiment deterioration rather than company-specific headwinds.
