On June 11, COHERENT fell 3.1% in after-hours trading, trading at $343.75/share, with trading volume of $13.85 million. The decline reflects continued selling pressure stemming from a bearish research report on co-packaged optics (CPO) technology.

On the news front, SemiAnalysis published a report on June 9 arguing that large-scale CPO commercialization has been pushed back to 2028-2029, significantly later than the market's prior expectation of full-volume deployment in 2027. Core bottlenecks cited include low optical engine yields, high co-packaging integration difficulty, and unfavorable system-level cost economics. The report triggered a sector-wide selloff, with COHERENT plunging over 11% on June 9 and falling another 11% intraday on June 10. Although NVIDIA executives publicly rebutted the report, stating CPO expansion and delivery would proceed as planned in the second half of the year, market panic has persisted. Within the Electronic Components sector, Corning fell 3.47% on the same day, reflecting broader sector weakness.
