SAXONBURG, Pa., August 12, 2026 – Coherent Corp. (NYSE: COHR)

(“Coherent,” “We,” or the “Company”), a global leader in photonics, announced financial results today for its fiscal fourth quarter and full year fiscal 2026 ended June 30, 2026.

Revenue for the fourth quarter of fiscal 2026 was $2.05 billion, with GAAP gross margin of 38.5% and GAAP net income of $1.19 per diluted share. On a non-GAAP basis, gross margin was 40.2% with net income per diluted share of $1.74.

“Fiscal 2026 was an

outstanding year for Coherent, with record revenue, significant margin expansion, and non-GAAP EPS growth that was more than twice the rate of revenue growth,” said Jim Anderson, CEO. “We enter

fiscal 2027 with exceptional customer demand, expanding production capacity, and multiple new growth platforms beginning to ramp. As AI datacenter architectures increasingly transition from copper to optical connectivity, we believe Coherent’s

broad photonic technology portfolio and manufacturing scale uniquely position us to deliver accelerating growth and capitalize on this multi-year opportunity.”

Sherri Luther, CFO, said, “Strong operational execution across our business drove meaningful gross margin expansion and converted our top-line revenue growth into robust GAAP and non-GAAP EPS growth. As we enter fiscal 2027, we remain disciplined in our capital allocation, prioritizing investments to expand

manufacturing capacity so we can efficiently fulfill the ongoing acceleration in customer demand.”

(1)

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.

(2)

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 administrative expenses, 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

2

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 – First Quarter Fiscal 2027(1)

Revenue for the first quarter of fiscal 2027 is expected to be between $2.2 billion and $2.4 billion.

Gross margin percentage for the first quarter of fiscal 2027 is expected to be between 39.5% and 41.5% on a non-GAAP basis.

Total operating expenses for the first quarter of fiscal 2027 are expected to be between $400 million and

$420 million on a non-GAAP basis.

Tax rate for the first quarter of fiscal 2027 is expected to be between 18% and 20% on a non-GAAP basis.

EPS for the first quarter of fiscal 2027 is expected to be between $1.85 and $2.05 on a non-GAAP basis.

(1)

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.

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.

(2)

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 to business divestitures.

(3)

Financing fees include debt extinguishment costs and various fees related to closing the new Credit Agreement

and repricing our Term Loan B as well as the conversion of Preferred Stock to Common Stock.

(4)

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.

(5)

Impairment of assets

held-for-sale relate to several entities classified as held-for-sale at June 30,

2026, December 31, 2025, September 30, 2025 and/or June 30, 2025.

(6)

Gain on sale of business is due to the sale of our aerospace and defense and Munich tools businesses.

(7)

Gain on sale of investment is due to the sale of shares in an equity method investment.

(8)

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.

For fiscal year 2026, the Company’s non-GAAP normalized tax rate is 19%. This projected

normalized tax rate was be applied to each quarter of fiscal year 2026. The Company’s non-GAAP normalized tax rate on non-GAAP net income may be adjusted during

the year to account for events or trends that the Company believes materially impact the original annual non-GAAP normalized tax rate including, but not limited to, significant changes resulting from tax

legislation, acquisitions or dispositions, entity structures or operational changes and other significant events. 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.

Fourth Quarter Fiscal 2026 August 12,

2026 Investor Presentation Exhibit 99.2

Forward-Looking Statements This

presentation contains forward-looking statements relating to future events and expectations, including our expectations regarding our estimates and projections for our business outlook for the first quarter of fiscal 2027, each of which is based on

certain assumptions and contingencies. The forward-looking statements are made pursuant to the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995 and relate to the Company’s performance on a going-forward

basis. 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 described in this presentation. The Company believes that

all forward-looking statements made by it herein 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 herein 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) our failure to accurately estimate

customer demand and future sales and/or fluctuations in purchasing patterns of customers and end users; (iv) the ability of the Company to retain and hire key employees; (v) the terms of the Company’s indebtedness and ability to service such

debt (vi) the timely release of new products and acceptance of such new products by the market; (vii) the introduction of new products by competitors and other competitive responses; (viii) the risks to realizing the benefits of investments in

R&D and commercialization of innovations; (ix) the risks that the Company’s stock price will not trade in line with industrial technology leaders; (x) the impact of international conflict and economic volatility in either domestic or

foreign markets, including risks related to the impact of trade protection measures, such as import tariffs by the United States or retaliatory actions taken by other countries; and/or (xi) the risks relating to forward-looking statements and other

“Risk Factors” identified from time to time in our filings with the 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 and Form 10-K, which

filings are available from the SEC. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. 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 August 12, 2026. 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 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

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.
