- Projected 22% CAGR in AI photonic components through 2030
Coherent Corp. (COHR) delivered a notable stock rally in mid-March 2026, fueled by robust demand for its photonic and optical networking solutions within AI data centers. The company reported revenue of $348 million for the quarter, marking a 29% year-over-year increase and surpassing analyst expectations by 8%. A key driver was the acceleration in deployment of AI infrastructure by major cloud providers, which increased demand for high-speed optical interconnects and transceivers—core products for COHR. The company’s gross margin expanded to 59.2%, up 120 basis points from the same period in 2025, reflecting improved manufacturing efficiency and favorable product mix. This margin improvement comes amid rising production volumes for 800G and 1.6T optical modules, which are critical for interconnecting AI accelerators. COHR also highlighted that orders for its next-generation silicon photonics platforms grew 45% sequentially, signaling sustained momentum. The positive performance has had ripple effects across the broader semiconductor and cloud infrastructure sector. Competitors such as NVIDIA (NVDA), AMD (AMD), and Intel (INTC) have seen elevated trading volumes and modest gains, as investors reprice valuations around AI infrastructure supply chains. Analysts note that COHR’s success underscores the growing importance of photonic components in AI hardware stacks, with demand projected to grow at a compound annual rate of 22% through 2030. Investors are now closely tracking supply chain dynamics, particularly the integration of optical technologies into AI server architectures. The market is pricing in continued strength for COHR and its peers as data center operators scale AI deployment, with implications for equipment vendors, packaging suppliers, and capital equipment providers.
