Coherent slides as investors digest Q3 beat, Q4 outlook and post-earnings run-up
Coherent shares fell after its May 6 fiscal Q3 2026 results and outlook, as investors focused on a Q4 revenue guide of $1.91B–$2.05B and non-GAAP EPS of $1.52–$1.72. The pullback follows a strong run and appears driven by guidance digestion and post-earnings profit-taking despite 21% year-over-year Q3 revenue growth to $1.81B.
1. What’s moving the stock today
Coherent (COHR) is down about 4.84% in the session as the market recalibrates after the company’s fiscal third-quarter 2026 report and forward outlook released May 6, 2026. Traders appear to be selling into the post-earnings tape, focusing on the company’s Q4 framework—revenue of $1.91 billion to $2.05 billion and non-GAAP EPS of $1.52 to $1.72—rather than the headline Q3 beat and upbeat AI datacenter demand commentary.
2. The numbers investors are reacting to
For fiscal Q3 2026 (ended March 31, 2026), Coherent reported revenue of $1.81 billion (+21% year over year), GAAP gross margin of 37.7%, and GAAP EPS of $0.97; on a non-GAAP basis, gross margin was 39.6% and EPS was $1.41. Management highlighted exceptionally strong demand in datacenter and communications, while the Q4 guide set the next bar the stock must clear, amplifying sensitivity to any perception that momentum is already priced in.
3. Context: strong AI optics narrative, but expectations are high
Coherent’s investor materials emphasize rapid datacenter and communications growth and ongoing capacity expansion tied to AI infrastructure. With the stock trading at elevated expectations following a major run, the day’s decline looks consistent with profit-taking and guidance digestion—an outcomes-versus-expectations trade—rather than a single newly disclosed negative operational event.
