Coherent Corp. is a global photonics leader whose lasers, transceivers, and optical components are central to artificial intelligence (AI) datacenter networks. Its fourth quarter of fiscal 2026, ended June 30, 2026, closed out a year in which AI-driven demand for high-speed optical connectivity reshaped the company’s revenue mix. The report carried extra weight because investors were looking for confirmation that accelerating datacenter orders could support the stock’s sharp run and justify continued capacity investments, while also watching how industrial demand and margin trends held up alongside the AI buildout.
For the fourth quarter of fiscal 2026, Coherent reported revenue of $2.05 billion, a 33.8% increase from $1.53 billion in the prior-year period and roughly 42% growth on a pro forma basis. The result topped consensus estimates near $1.99 billion. Non-GAAP EPS came in at $1.74, up 74% from $1.00 a year earlier and above the $1.62 consensus forecast.
On a GAAP (Generally Accepted Accounting Principles) basis, net income attributable to Coherent was $240.5 million, or $1.19 per diluted share, compared with a net loss of $95.6 million, or $0.83 per share, in the year-ago quarter. GAAP gross margin rose to 38.5% from 35.7%, while non-GAAP gross margin reached 40.2%.
Datacenter and Communications revenue grew 59% year over year and represented about 79% of total revenue, while Industrial revenue grew 1%. For full-year fiscal 2026, revenue reached $7.12 billion, up 22.5% from fiscal 2025. Chief Executive Officer Jim Anderson said fiscal 2026 was “an outstanding year” marked by record revenue, margin expansion, and non-GAAP EPS growth more than twice the rate of revenue growth.
For the first quarter of fiscal 2027, Coherent guided revenue to $2.2 billion–$2.4 billion and non-GAAP EPS to $1.85–$2.05, with midpoints above the consensus estimates of approximately $2.14 billion and $1.77, respectively.

Coherent shares rose about 8% in the regular session following the report, reflecting a beat-and-raise quarter, but gave back roughly 3% in extended trading as investors weighed the strong results against the stock’s substantial prior gains and elevated valuation. The mixed after-hours move highlighted a familiar dynamic: AI-linked demand remains robust, yet expectations heading into the print were already high.
Investor sentiment was supported by record revenue, accelerating datacenter growth, and above-consensus guidance. Offsetting those positives were heavy capital expenditures of $556 million in the quarter and negative free cash flow, as the company invests aggressively to expand production capacity. The reaction suggests the market acknowledged execution while remaining sensitive to valuation and the cost of scaling.
The first quarter of fiscal 2027 will be the next major checkpoint. Management’s revenue guidance of $2.2 billion–$2.4 billion implies a meaningful sequential step-up, and investors will watch whether Coherent can sustain that ramp while protecting margins. Non-GAAP gross margin of 40.2% in the fourth quarter keeps the company within reach of its longer-term targets, but quarterly progress will depend on product mix and capacity utilization.
Capacity expansion is a central theme. Coherent is working to double internal indium phosphide production capacity, a key enabler for high-speed optical components, and has pointed to multi-year demand visibility, with customer orders extending into calendar 2028. A previously announced $2 billion investment from NVIDIA and a multiyear co-packaged optics (CPO) supply agreement add strategic weight, though new production ramps carry execution risk.
Other factors to monitor include the pace of capital spending, free cash flow trends, the performance of the smaller Industrial segment, and broader datacenter spending patterns across AI infrastructure. The balance between rapid growth and the cost of enabling that growth will remain a key area of focus for investors.
