**PRESS RELEASE** 

**COHERENT CORP. REPORTS FIRST QUARTER FISCAL 2026 RESULTS** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Q1 REVENUE OF $1.58B, INCREASED 17% Y/Y AND, ON A PRO FORMA BASIS, 19% Y/Y ADJUSTED FOR SALE OF AEROSPACE & DEFENSE BUSINESS** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Q1 GAAP GROSS MARGIN OF 36.6%, INCREASED 249 bps Y/Y; Q1 NON-GAAP GROSS MARGIN OF 38.7%, INCREASED 200 bps Y/Y** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** **Q1 GAAP EPS OF $1.19, IMPROVED $1.23 Y/Y; Q1 NON-GAAP EPS OF $1.16, IMPROVED $0.49 Y/Y** 

SAXONBURG, Pa., November 5, 2025 (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 2026 ended September 30, 2025.

Revenue for the first quarter of fiscal 2026 was $1.58 billion, with GAAP gross margin of 36.6% and GAAP net income of $1.19 per diluted share. On a non-GAAP basis, gross margin was 38.7% with net income per diluted share of $1.16.

Jim Anderson, CEO, said, "Revenue growth of 19% year-over-year in the September quarter on a pro forma basis was driven by strong demand from AI-related datacenters and communications. We expect continued strong growth throughout this fiscal year based on increasing datacenter and communications demand along with our continued production capacity expansion."

Sherri Luther, CFO, said, "Significant revenue growth and gross margin expansion drove a year-over-year increase in our GAAP and non-GAAP EPS. During the quarter, we paid down $400 million of our debt. We also refinanced our debt which will reduce our interest expense and further strengthen our balance sheet."

<sup>(1)</sup> 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. 

<sup>(2)</sup> The Company has disclosed financial measurements in this earnings release that present financial information 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.

**Highlights from First Quarter Fiscal 2026** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Closed Sale of Aerospace and Defense Business.** We closed the sale of our Aerospace and Defense business.
The transaction is immediately accretive to both gross margin and EPS.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Introduced a High-Power 400 mW CW Laser for Co-Packaged Optics (CPO) and Silicon Photonic Designs.** We are currently sampling to multiple customers our new 400 mW CW lasers, which offer best in class performance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **ECOC'25 Award for Most Innovative Photonic Component.** Industry's first 400G Differential-EML to enable power and cost efficient 3.2T data center transceivers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Extending the Reach of 1.6T Direct Detect Transceivers to 6 km.** Through a unique embedded dispersion
compensation technique, we demonstrated 6 km 1.6T links based on EMLs, offering a cost-effective and lower-power alternative for scale across networks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Demonstrated a Next-Gen 2D VCSEL Array-Based Solution for AI Scale-up Networks.** These arrays represent a breakthrough in short-reach optical interconnects for Near-Packaged Optics (NPO) and Co-Packaged Optics (CPO), which enable
compact, power-efficient links for the scale-up portion of AI networks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **ECOC'25 Award for Optical Transport.** Our Multi-Rail Technology platform leverages
advanced optical amplification technology enabling unprecedented levels of power, space and cost efficiency.

**Business Outlook – Second Quarter Fiscal 2026<sub>(</sub><sub>1</sub><sub>)</sub>** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenue for the second quarter of fiscal 2026 is expected to be between $1.56 billion and
$1.70 billion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gross margin percentage for the second quarter of fiscal 2026 is expected to be between 38% and 40% on a non-GAAP basis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total operating expenses for the second quarter of fiscal 2026 are expected to be between $300 million and
$320 million on a non-GAAP basis.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• EPS for the second quarter of fiscal 2026 is expected to be between $1.10 and $1.30 on a non-GAAP basis.

<sup>(1)</sup> 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.

As part of this calculation, we also added back the preferred cash dividend to earnings used to calculate diluted earnings per share.

<sup>(1)</sup> 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. 

<sup>(2)</sup> Integration, site consolidation and other costs include retention and severance payments and other integration costs related to the acquisition of Coherent, Inc., implementation of common technology systems and costs related business divestitures.

<sup>(3)</sup> Financing fees includes debt extinguishment costs and various fees related to closing the new Credit Agreement and repricing our Term Loan B.

<sup>(4)</sup> Restructuring charges include non-cash impairment charges for production assets and improvements on leased facilities, loss on sale of a facility, severance, contract termination costs and other costs related to the restructuring plans.

<sup>(5)</sup> Impairment of assets held-for-sale relate to several entities classified as held-for-sale at September 30, 2025 and/or June 30, 2025.

<sup>(6)</sup> Gain on sale of business is due to the sale of our aerospace and defense business.

<sup>(7)</sup> Gain on sale of investment is due to the sale of shares in an equity method investment.

<sup>(8)</sup> The Company adopted a full-year, normalized tax rate for the computation of the non-GAAP income tax provision for fiscal year 2026. We believe this approach provides investors with a more consistent view of our underlying operating performance. In estimating the full-year non-GAAP normalized tax rate, the Company utilized a full-year financial projection that considers multiple factors such as changes to the Company's current operating structure, expected reserve changes for the year, and other significant tax matters to the extent they are applicable to the full fiscal year financial projection. In addition to the adjustments described above, this normalized tax rate excludes the impact of share-based awards, amortization of acquisition-related intangible assets, integration and restructuring charges, foreign exchange gain/(loss), and certain tax valuation allowances. 

The first quarter and full-year fiscal year 2026 outlook assume a projected annual effective tax rate of 19% for non-GAAP unless adjusted for material events. The non-GAAP tax rate utilized in future periods will be reviewed annually to determine whether it remains appropriate in consideration of our financial results. These additional non-GAAP financial measures should not be considered substitutes for any measures derived in accordance with GAAP and may be inconsistent with similar measures presented by other companies.

(1) The total number of shares used to calculate earnings per share in Q1 increased to 190.7 million, primarily
because of accounting rules that require us to include our Series B Preferred Shares as if they were converted into common shares. As part of this calculation, we also added back the preferred cash dividend to earnings used to calculate diluted
earnings per share.

The forward-looking statements in this investor presentation involve risks and uncertainties, which could cause actual results, performance, or trends to differ materially from those expressed in the forward-looking statements herein or in previous disclosures. The Company believes that all forward-looking statements made by it in this presentation have a reasonable basis, but there can be no assurance that management's expectations, beliefs, or projections as expressed in the forward-looking statements will actually occur or prove to be correct. In addition to general industry and global economic conditions, factors that could cause actual results to differ materially from those discussed in the forward-looking statements in this presentation include but are not limited to: (i) the failure of any one or more of the assumptions stated herein to prove to be correct; (ii) changes in demand in the Company's end markets along with the Company's ability to respond to such market changes; (iii) risks relating to future integration and/or restructuring actions; (iv) fluctuations in purchasing patterns of customers and end users; (v) the ability of the Company to retain and hire key employees; (vi) the terms of the Company's indebtedness and ability to service such debt in connection with its acquisition of Coherent, Inc.; (vii) the timely release of new products and acceptance of such new products by the market; (viii) the introduction of new products by competitors and other competitive responses; (ix) the Company's ability to assimilate other recently acquired businesses, and realize synergies, cost savings, and opportunities for growth in connection therewith, together with the risks, costs, and uncertainties associated with such acquisitions; (x) the risks to realizing the benefits of investments in R&D and commercialization of innovations; (xi) the risks that the Company's stock price will not trade in line with industrial technology leaders; (xii) the impact of trade protection measures, such as import tariffs by the United States or retaliatory actions taken by other countries; and/or (xiii) the risks relating to forward-looking statements and other "Risk Factors" identified from time to time in our filings with the Securities and Exchange Commission ("SEC"), including our Annual Report on Form 10-K for the fiscal year ended June 30, 2025, and our subsequently filed Quarterly Reports on Form 10-Q, which filings are available from the SEC. The Company disclaims any obligation to update information contained in these forward-looking statements, whether as a result of new information, future events or developments, or otherwise. Unless otherwise indicated in this presentation, all information in this presentation is as of November 5, 2025. This presentation contains non-GAAP financial measures and key metrics relating to the Company's past performance. We believe the presentation of these non-GAAP financial measures enhances investors' overall understanding of our historical financial performance and assists investors in comparing our performance across reporting periods. These non-GAAP financial measures are in addition to, and not as a substitute for or superior to, measures of financial performance prepared in accordance with U.S. GAAP. There are a number of limitations related to the use of these non-GAAP financial measures versus their nearest GAAP equivalents. For example, other companies may calculate non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. As required by Regulation G, we have provided reconciliations of those measures to the most directly comparable GAAP measures in the section captioned "GAAP to NON-GAAP RECONCILIATION." 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.
