On June 23, Applied Optoelectronics fell 5.54% in pre-market trading, trading at $158.93/share, with turnover of $10.538 million.

On the news front, the decline is primarily driven by persistent industry headwinds stemming from a SemiAnalysis report indicating that large-scale CPO (Co-Packaged Optics) adoption may be delayed until 2028 or even 2029, with system-level yields potentially as low as approximately 19.4% — far below market expectations for near-term rapid volume ramp. This bearish assessment continues to suppress valuations across the optical communications sector.

Within the Communication Equipment sector, the overall sector is broadly under pressure. Among individual stocks, Nokia Oyj down 7.48%, Lumentum down 6.59%, Ciena down 6.06%, Arista Networks down 4.11%, and Cisco down 1.44%.

Applied Optoelectronics is a leading supplier of fiber-optic networking products, with operations focused on cable television, fiber-to-the-home, and data center networking markets. It is one of the few U.S.-based manufacturers with in-house InP laser production capabilities for AI optical modules.
