SAXONBURG, Pa., November 4, 2026 (GLOBE NEWSWIRE) – Coherent Corp. (NYSE: COHR)

(“Coherent,” “We,” or the “Company”), a global leader in photonics, announced financial results today for its first quarter of fiscal year 2027 ended September 30, 2026.

Revenue for the first quarter of fiscal 2027 was $2.37 billion, with GAAP gross margin of 39.1% and GAAP net income of $1.90 per diluted share. On a non-GAAP basis, gross margin was 40.6% with net income per diluted share of $2.09.

“Q1 marked a strong start to fiscal 2027, with pro forma revenue up 56% year over year and non-GAAP EPS up 80%,” said Jim Anderson, CEO. “Our established businesses delivered strong growth, while new growth areas are beginning to ramp. As AI datacenters transition from copper to optical connectivity, Coherent’s broad photonics platform and manufacturing scale position us to help customers meet rising needs for bandwidth and energy efficiency. We expect fiscal 2027 pro forma revenue growth to exceed 60%.”

Sherri Luther, CFO, said, “Our Q1 results delivered substantial operating leverage and durable gross margin expansion, driven by pricing optimization and cost improvements. This margin strength gives us the confidence to raise our longer-term target. We expect to achieve our first quarter with non-GAAP gross margin above 45% before the end of calendar 2028.”

Operating Income is defined as earnings before income taxes, interest expense, and other expense or income, net.

Additional Revenue and Gross Margin Guidance

• Expect to achieve our first $3 billion revenue quarter by the end of fiscal 2027.

• Expect fiscal 2027 pro forma revenue growth to exceed 60%, more than double our fiscal 2026 pro forma growth rate.

• Expect first $4 billion revenue quarter in fiscal 2028.

• New Gross Margin Target; Expect to achieve our first quarter with non-GAAP gross margin above 45% before the end of calendar 2028.

The Company has not provided a quantitative reconciliation of forward-looking non-GAAP gross margin percentage, non-GAAP operating expenses, non-GAAP tax rate and non-GAAP earnings per share, because we cannot, without unreasonable efforts, forecast certain items required to develop comparable GAAP measures. These items include, without limitation, restructuring charges, integration, site consolidation and other expenses, foreign exchange gains (losses), and share based compensation expense. The variability of these items could significantly impact our future GAAP financial results and we believe that the inclusion of any such reconciliations would imply a degree or precision that could be confusing or misleading to investors.
