Coherent Stock Jumps 9% on SiC Breakthrough for AI Data Centers

Coherent Corp.’s shares jumped 9% after the company announced significant advances in its silicon carbide (SiC) epitaxy technology, signaling a direct challenge to incumbents in the high-growth market for AI data center components.

The company’s announcement on April 10 detailed improvements in the manufacturing of SiC wafers, a critical material for managing power and heat in next-generation AI systems. "These advances in SiC epitaxy reinforce our position to capitalize on the explosive growth in AI," the company stated in its press release, highlighting the material's superior performance over traditional silicon.

The stock rose as much as 9% on the news, reflecting investor optimism that the breakthrough will allow Coherent to capture a larger share of the component market for AI hardware. The advance in epitaxy, the process of growing a thin crystalline layer on a substrate, is crucial for producing the high-quality, large-diameter SiC wafers needed for power-semiconductors in data centers running hardware from companies like Nvidia and AMD. Coherent did not disclose the specific process node or production timeline for the new technology.

The development positions Coherent to better compete with established SiC players like Wolfspeed and STMicroelectronics. As AI models become more powerful, the demand for efficient power semiconductors to manage electricity consumption and thermal output is soaring. This technological advance could strengthen Coherent's market position as a critical supplier, potentially leading to increased revenue and attracting further investment into the optical networking and semiconductor sectors.
