Steve Cohen trims Coherent stake despite $2B NVIDIA deal and AI momentum

Billionaire Steve Cohen's Point72 Asset Management has trimmed its stake in Coherent Corp., reducing its holding by nearly 14% to 3.3 million shares in the fourth quarter of 2025. The fund has held the position since Q2 2023, building it to 4.2 million shares by Q2 2024 before recent reductions. Coherent has attracted hedge fund interest following a multi-year strategic agreement with NVIDIA, which is investing $2 billion to expand the company's R&D and US manufacturing capacity. The deal positions Coherent as NVIDIA's primary supplier for its 2027-2028 hardware roadmap, particularly in silicon photonics and co-packaged optics for AI infrastructure. In Q2 fiscal 2026, Coherent reported revenue of $1.7 billion, exceeding analyst estimates, driven by strong demand for optical networking products.

Coherent and Tower Semiconductor achieve 400 Gbps silicon photonics breakthrough for 3.2T optical transceivers

Coherent Corp. and Tower Semiconductor announced a breakthrough demonstrating 400 Gbps-per-lane silicon photonics data transmission for next-generation 3.2T optical transceivers. The development, revealed in late March 2026, targets AI datacentres and co-packaged optics applications. The collaboration combines Coherent's InP laser technology with Tower's silicon photonics platform, supporting the company's AI datacentre optics strategy alongside its existing NVIDIA multi-year agreement. Coherent also presented at ICDT 2026 in Chongqing and SEMICON China 2026 in Shanghai. Analysts project Coherent's revenue could reach $11.4 billion by 2029, requiring 22% yearly growth. However, investors face risks from heavy capital expenditure requirements and potential margin pressure from intense competition, even as the silicon photonics milestone strengthens the company's position in high-speed optical links.
