Coherent Rerates as AI Infrastructure Leader Following Strong Q3 Earnings Surge

Amid the accelerating global race to expand cloud computing infrastructure, Coherent has delivered robust Q3 results that signal a fundamental shift in its business model. The company reported a 27% increase in revenue and a 55% surge in earnings per share (EPS), driven by its data center exposure rising to 75%. According to reports, the firm is successfully transitioning from a cyclical optical supplier to a strategic AI infrastructure enabler, supported by strong backlog visibility extending through 2028.

This performance aligns with a broader sector rerating seen across AI hardware peers; market data shows significant growth trajectories for companies like Nvidia and Broadcom as they scale to meet hyperscale data center demands. Compared to previous quarters, Coherent's 27% revenue jump underscores its critical role in producing indium phosphide for AI ecosystems. This strategic pivot has led to a valuation rerating, as investors move away from viewing the stock through a cyclical lens toward a structural growth narrative.

Looking ahead, traders are monitoring Coherent shares (0HYA.L) to gauge the sustainability of this momentum following the May 2026 closes. Key catalysts in the upcoming economic calendar include speeches from Federal Reserve officials, such as Governor Waller on May 19, 2026. These updates will be crucial for assessing the interest rate environment, which directly impacts the capital expenditure budgets of the big tech firms driving AI infrastructure demand.
