On June 25, Lumentum Holdings rose 3.02% in after-hours trading, trading at 867.81 USD/share, with turnover of approximately $198 million. The gain was primarily driven by a continued recovery across the communication equipment sector and the reinforcement of a new growth narrative around near-packaged optics (NPO) technology.

On the sector front, communication equipment stocks broadly strengthened, with Applied Optoelectronics up 4.31%, Ciena up 3.15%, Arista Networks up 2.94%, and Nokia up 2.82%, generating positive linkage effects. On the company-specific front, Lumentum's CEO previously stated at the Mizuho Technology Conference that the NPO opportunity could be larger than co-packaged optics (CPO), with mass production expected in the second half of 2027 and significantly increased laser demand per rack. This narrative has continued to offset market concerns over CPO production delays flagged by SemiAnalysis, which warned of timelines slipping to 2028-2029 due to system-level yields of only approximately 19%.
