Movement Alert|Lumentum Holdings Overnight Decline 3.01%, Communication Equipment Sector Weakens Amid Persistent CPO Mass Production Delay Concerns

Market Focus06-26

On June 26, Lumentum Holdings declined 3.01% overnight, trading at approximately $831.87/share, with turnover of $6.49 million.

On the news front, the communication equipment sector broadly weakened, with sector peers Applied Optoelectronics down 5.46%, Nokia down 3.36%, Ciena down 2.28%, and Arista Networks down 1.20%, with sector-wide linkage effects intensifying selling pressure on individual stocks. Meanwhile, independent research firm SemiAnalysis previously published a report indicating that co-packaged optics (CPO) mass production timelines may be delayed to 2028 or even 2029, with system-level yields at only approximately 19% — far below production-ready standards. This fundamental concern over CPO delays continues to weigh on optical communications sentiment.

Notably, while the company's CEO had previously highlighted near-packaged optics (NPO) technology as a potentially larger opportunity than CPO at a Mizuho technology conference, projecting volume production by the second half of 2027, the underlying CPO delay concerns have not been fully resolved and continue to suppress sector valuations.
