SAXONBURG, Pa., May 6, 2026 (GLOBE NEWSWIRE) – Coherent Corp. (NYSE: COHR) (“Coherent,”

“We,” or the “Company”), a global leader in photonics, announced financial results today for its third quarter of fiscal year 2026 ended March 31, 2026.

Revenue for the third quarter of fiscal 2026 was $1.81 billion, with GAAP gross margin of 37.7% and GAAP net income of $0.97 per diluted share. On a non-GAAP basis, gross margin was 39.6% with net income per diluted share of $1.41.

“We delivered another quarter of strong financial performance, with accelerating revenue growth, expanding margins, and improving profitability, driven by exceptionally strong demand across our datacenter and communications businesses,” said Jim Anderson, CEO. “As AI datacenter infrastructure continues to scale, we are rapidly expanding capacity to meet demand. With the breadth of our photonic technology portfolio and our manufacturing scale, we believe Coherent is uniquely well positioned to capitalize on this multi-year growth opportunity.”

Sherri Luther, CFO, said, “Significant revenue growth together with gross margin expansion drove a year-over-year increase in our GAAP and non-GAAP EPS. We remain focused on ramping our capital investment to drive increased capacity given our strong visibility into ongoing robust demand.”

During the second fiscal quarter of 2025, the Company refined its methodology to report non-GAAP measures. The change does not impact the Company’s financial position, cash flows, or GAAP consolidated results of operations. Prior period non-GAAP financial measures presented in this press release have been recast to conform to the current presentation.

The Company has disclosed financial measurements in this earnings release that present financial information that are considered to be non-GAAP financial measures. These measurements are not a substitute for GAAP measurements, although the Company’s management uses these measurements as an aid in monitoring the Company’s on-going financial performance. The non-GAAP net earnings attributable to Coherent Corp., the non-GAAP diluted earnings per share, the non-GAAP operating income, the non-GAAP gross margin, the non-GAAP research and development, the non-GAAP selling, general and administration, the non-GAAP operating expenses, the non-GAAP interest and other (income) expense, and the non-GAAP income taxes, measure earnings and operating income (loss), respectively, excluding non-recurring or unusual items that are considered by management to be outside the Company’s standard operation and excluding certain non-cash items. There are limitations associated with the use of non-GAAP financial measures, including that such measures may not be entirely comparable to similarly titled measures used by other companies, due to potential differences among calculation methodologies. Thus, there

can be no assurance whether (i) items excluded from the non-GAAP financial measures will occur in the future or (ii) there will be cash costs associated with items excluded from the non-GAAP financial measures. The Company compensates for these limitations by using these non-GAAP financial measures as supplements to GAAP financial measures and by providing the reconciliations of the non-GAAP financial measures to their most comparable GAAP financial measures. Investors should consider adjusted measures in addition to, and not as a substitute for, or superior to, financial performance measures prepared in accordance with GAAP. All non-GAAP amounts exclude certain adjustments for share-based compensation, acquired intangible amortization expense, restructuring charges (recoveries), impairments of assets held-for-sale, gains on sale of business, integration and site consolidation expenses, integration transaction expenses, and various one-time adjustments. See Table 6 for the Reconciliation of GAAP measures to non-GAAP measures.

Business Outlook – Fourth Quarter Fiscal 2026 (1)

• Revenue for the fourth quarter of fiscal 2026 is expected to be between $1.91 billion and $2.05 billion.

• Gross margin percentage for the fourth quarter of fiscal 2026 is expected to be between 39.0% and 41.0% on a non-GAAP basis.

• Total operating expenses for the fourth quarter of fiscal 2026 are expected to be between $360 million and $380 million on a non-GAAP basis.

• Tax rate for the fourth quarter of fiscal 2026 is expected to be between 18% and 20% on a non-GAAP basis.

• EPS for the fourth quarter of fiscal 2026 is expected to be between $1.52 and $1.72 on a non-GAAP basis.

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.
