Coherent Slips 3.44% in Premarket Despite Strong Quarter, as Investors Weigh Valuation Against Growth
Coherent Corp. is trading lower by 3.44% in premarket today, a counterintuitive reaction to what was by most measures a genuinely strong third quarter fiscal 2026 earnings report. The decline likely reflects profit-taking after a period of elevated expectations, rather than any fundamental concern with the results themselves — a classic "buy the rumor, sell the news" dynamic in a stock that has benefited from intense investor enthusiasm around AI infrastructure spending.
Revenue for the quarter ended March 31, 2026 came in at $1.81 billion, a 21% increase year-over-year on a reported basis and 27% on a pro forma basis. Both figures point to a business riding a powerful and durable demand wave. Gross margin expanded meaningfully, with the GAAP figure coming in at 37.7%, up 243 basis points year-over-year, while the non-GAAP gross margin reached 39.6%, up 105 basis points. The direction of travel on margins is clearly positive, and the pace of improvement suggests that operating leverage is beginning to assert itself as volumes scale.
Earnings per share told a similar story of rapid improvement. GAAP EPS reached $0.97 per diluted share, a $1.08 improvement year-over-year that reflects both the stronger revenue base and the absence of charges that weighed on the prior year period. Non-GAAP EPS came in at $1.41, up $0.50 year-over-year, demonstrating that the underlying cash earnings power of the business is compounding at a meaningful rate.
The driving force behind the results is no mystery. CEO Jim Anderson pointed directly to exceptionally strong demand across the company's datacenter and communications businesses, with AI infrastructure buildout at the center of the growth story. Coherent occupies a strategically important position in the AI supply chain as a maker of photonic components — the transceivers, lasers, and optical networking technology that move data between chips, servers, and data centers at the speeds that modern AI workloads demand. As hyperscalers continue to pour hundreds of billions of dollars into AI infrastructure, the need for high-speed optical interconnects is scaling in lockstep, and Coherent is one of a small number of companies with the photonic technology portfolio and manufacturing scale to meet that demand.
CFO Sherri Luther reinforced that the company's visibility into ongoing demand remains strong, and noted that the company is actively ramping capital investment to expand capacity. That capital commitment is a signal of confidence in the durability of the growth cycle, not a sign of strain — management is investing because customers are asking for more product than Coherent can currently supply.
The 3.44% premarket decline, against this backdrop of accelerating revenue growth, expanding margins, and rising earnings, is best read as a valuation adjustment rather than a fundamental reassessment. Stocks that have run hard on AI optimism are held to an exceptionally high standard at earnings time, and even a strong quarter can disappoint a market that had priced in perfection. For investors with a longer horizon, the underlying trajectory — faster growth, better margins, a critical position in the AI infrastructure stack — remains firmly intact.
