Coherent Corp shares came under pressure as investors weighed the company’s heavy push into advanced optical networking hardware against broader market worries about tech spending. The stock move followed news that Coherent is showcasing ultra‑fast 1.6T to 12.8T architectures and next‑gen co‑packaged optics at the OFC 2026 conference.

Despite the slide, Wall Street remains upbeat on the long‑term story. Stifel raised its price target and reiterated a Buy rating, pointing to strong expected demand from AI data centers for Coherent’s high‑speed 400G‑per‑lane links and multi‑technology optical solutions.
