Coherent Corp. and Subsidiaries

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1.    Basis of Presentation

Basis of Presentation

The condensed consolidated financial statements of Coherent Corp. (“Coherent”, the “Company”, “we”, “us” or “our”) for the three and nine months ended March 31, 2026 and 2025 are unaudited. In the opinion of management, all adjustments considered necessary for a fair presentation for the periods presented have been included. All adjustments are of a normal recurring nature unless disclosed otherwise. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2025 filed with the Securities and Exchange Commission (the “SEC”) on August 15, 2025 and in Exhibit 99.1 to our Current Report on Form 8-K dated December 16, 2025 in which we retrospectively recast historical segment reporting to reflect our current organizational structure. The condensed consolidated results of operations for the three and nine months ended March 31, 2026 are not necessarily indicative of the results to be expected for the full fiscal year. The Condensed Consolidated Balance Sheet information as of June 30, 2025 was derived from the Company’s audited consolidated financial statements.

Certain prior year amounts have been reclassified for consistency with the current year presentation.

Note 2.    Recently Issued Financial Accounting Standards

In December 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, on either a prospective or retrospective basis. Early adoption is permitted. ASU 2023-09 is effective for the Company’s year beginning July 1, 2025 and the new disclosure requirements will be reflected in the Company’s Annual Report on Form 10-K for the year ending June 30, 2026.

In November 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40), Disaggregation of Income Statement Expenses.” This ASU requires disclosure about specific types of expenses included in expense captions including purchases of inventory, employee compensation, depreciation, amortization, and depletion. This ASU is effective for our annual disclosures starting in fiscal year 2028 and interim periods starting in fiscal year 2029. Early adoption is permitted. A public entity should apply the amendments in this ASU on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

Note 3.    Revenue from Contracts with Customers

We disaggregate revenue by market and geography. We believe that disaggregating revenue by market and geography provides the most relevant information regarding the nature, amount, timing, and uncertainty of revenues and cash flows. We do not present other levels of disaggregation, such as by type of products, customer, contracts, duration of contracts, timing of transfer of control and sales channels, as this information is not used by our chief operating decision maker (“CODM”) to manage the business.

Effective July 1, 2025, the Company aligned its reporting of revenues into two markets: (i) Datacenter & Communications, and (ii) Industrial. All prior period market and segment disclosure information has been reclassified to conform to the current reporting structure.

10

The following tables summarize disaggregated revenue by market ($000):

	Three Months Ended March 31,				Nine Months Ended March 31,
Markets	2026		2025		2026		2025
Datacenter & Communications	$	1,361,677	$	968,650	$	3,659,627	$	2,736,838

Total Revenues	$	1,805,641	$	1,497,879	$	5,072,648	$	4,280,679

Contract Liabilities

Payments received from customers are based on invoices or billing schedules as established in contracts with customers. Contract liabilities generally relate to payments received in advance of performance under the contract. Contract liabilities are recognized as revenue when the performance obligations have been satisfied. During the nine months ended March 31, 2026, we recognized revenue of $52 million related to customer payments that were included as contract liabilities in the Condensed Consolidated Balance Sheet as of June 30, 2025. We had $70 million of contract liabilities recorded in the Condensed Consolidated Balance Sheet as of March 31, 2026. As of March 31, 2026, $59 million of contract liabilities is included within Other accrued liabilities, and $11 million is included within Other liabilities on the Condensed Consolidated Balance Sheet.

Note 6.    Goodwill and Other Intangible Assets

Effective July 1, 2025, the Company realigned its organizational structure into two reporting segments: (i) Datacenter & Communications, and (ii) Industrial. The information in the table below reflects the impact of this segment change whereby goodwill was reallocated to the respective reporting units on the first day of fiscal 2026 using a relative fair value approach. As a result of the change in reportable segments, the Company performed an impairment assessment immediately before and immediately after the segment change became effective, and no impairment of goodwill was identified.

Changes in the carrying amount of goodwill were as follows ($000):

(1) Other reclassifications include adjustments to goodwill classified as held-for-sale. See Note 7. Assets Held-for-Sale and Sale of Business for further information.

We test goodwill for impairment annually during the fourth quarter of our fiscal year, or more frequently when events or changes in circumstances indicate that fair value is below carrying value.

The gross carrying amount and accumulated amortization of our intangible assets other than goodwill were as follows ($000):

	March 31, 2026						June 30, 2025
	Gross Carrying Amount		Accumulated Amortization		Net Book Value		Gross Carrying Amount		Accumulated Amortization		Net Book Value

Note 7.        Assets Held-for-Sale and Sale of Business

In the fourth quarter of fiscal 2025, management entered into non-binding agreements to sell several entities. As a result of classifying these entities as held-for-sale, the Company recorded non-cash impairment charges of $85 million within the Industrial segment. These charges were recognized in Impairment of assets held-for-sale in our Condensed Consolidated Statements of Earnings (Loss) in the fourth quarter of fiscal 2025 to reduce the carrying values of the entities to their estimated fair value.

On September 2, 2025, the Company completed the sale of its aerospace and defense business, which was part of the Industrial segment, for approximately $400 million, subject to customary post-closing adjustments. In connection with the sale, the Company recorded a gain of $115 million and incurred approximately $9 million in transaction related costs which were recorded in Gain on sale of business and SG&A expenses, respectively, in the Condensed Consolidated Statements of Earnings (Loss) for the first quarter of fiscal 2026.

In the nine months ended March 31, 2026, the Company recorded additional non-cash impairment charges of $20 million within the Industrial segment related to two entities that were classified as held-for-sale during the first and second quarters of fiscal 2026. The charges were recorded in Impairment of assets held-for-sale in the Condensed Consolidated Statements of Earnings (Loss) for the first and second quarters of fiscal 2026 to reduce the carrying value of entities classified as held-for-sale to their estimated fair value.

On January 30, 2026, the Company completed the sale of its product division based in Munich, Germany that makes tools for materials processing. In connection with the sale, the Company recorded a gain of $9 million which was recorded in Gain on sale of business in the Condensed Consolidated Statements of Earnings (Loss) for the third quarter of fiscal 2026. The total loss associated with the sale was $96 million, substantially all of which was recognized in Impairment of assets held-for-sale in the Condensed Consolidated Statements of Earnings (Loss), including $81 million in the fourth quarter of fiscal 2025, $13 million in the first quarter of fiscal 2026 and $11 million in the second quarter of fiscal 2026.

Senior Credit Facilities

On July 1, 2022 (the “Closing Date”), Coherent entered into a credit agreement (the “Credit Agreement”) by and among the Company, as borrower (in such capacity, the “Borrower”), the lenders, and other parties thereto, and JP Morgan Chase Bank, N.A., as administrative agent and collateral agent, which provided for senior secured financing of $4.0 billion, consisting of a term loan A credit facility (the “Term A Facility”) maturing July 1, 2027, with an aggregate principal amount of $850 million, a term loan B credit facility (the “Term B Facility,” and together with the Term A Facility, the “Term Facilities”) maturing July 1, 2029, with an aggregate principal amount of $2,800 million, and a revolving credit facility (the “Revolving Credit Facility,” and together with the Term Facilities, the “Senior Credit Facilities”) maturing July 1, 2027, in an aggregate available amount of $350 million, including a letter of credit sub-facility of up to $50 million. On the Closing Date, the Borrower and certain of its direct and indirect subsidiaries provided a guaranty of all obligations of the Borrower and the other loan parties under the Credit Agreement and the other loan documents, secured cash management agreements and secured hedge agreements with the lenders and/or their affiliates (subject to certain exceptions). The Borrower and the other guarantors have also granted a security interest in substantially all of their assets to secure such obligations. On March 31, 2023, Coherent entered into Amendment No. 1 to the Credit Agreement, which replaced the adjusted LIBOR-based rate of interest therein with an adjusted SOFR-based rate of interest. On April 2, 2024, Coherent entered into Amendment No. 2 to the Credit Agreement, under which the principal amount of term B loans outstanding under the Credit Agreement (the “Existing Term B Loans”) were replaced with an equal amount of new term loans (the “New Term B Loans”) having substantially similar terms as the Existing Term B Loans, except with respect to the interest rate applicable to the New Term B Loans and certain other provisions. On January 2, 2025, Coherent entered into Amendment No. 3 to the Credit Agreement, under which the principal amount of New Term B Loans outstanding under the Credit Agreement were replaced with an equal amount of new term loans (the “New Term B-2 Loans”) having substantially similar terms as the New Term B Loans, except with respect to the interest rate applicable to the New Term B-2 Loans and certain other provisions. The maturity of the New Term B-2 Loans and Revolving Credit Facility was unchanged.

On September 26, 2025, the Company entered into Amendment No. 4 (“Amendment No. 4”) and Amendment No. 5 (“Amendment No. 5”) to the Credit Agreement. Under Amendment No. 4, (i) the existing revolving credit commitments were refinanced and replaced with new senior secured revolving credit commitments, (ii) $350 million of senior secured incremental revolving credit commitments were added, increasing the total revolving credit facility to $700 million (the “2025 Revolving Loans”), including a letter of credit sub-facility of up to $100 million, and (iii) a $1,250 million new tranche of senior secured incremental term A loans was added (the “2025 Incremental Term A Loans”), the proceeds of which were used, in part, to repay all outstanding principal, interest and fees of term A loans outstanding under the Credit Agreement (the “Existing Term A Loans”). As amended, the 2025 Revolving Loans and the 2025 Incremental Term A Loans each bear interest at an adjusted SOFR rate subject to a 0.00% floor plus a range of 1.25% to 2.25% based on the Company’s total net leverage ratio. The interest rate applicable to the 2025 Revolving Loans and the 2025 Incremental Term A Loans is initially a SOFR-based rate plus 1.50% as of March 31, 2026. The 2025 Revolving Loans and the 2025 Incremental Term A Loans mature on the earlier of September 26, 2030 or a “Springing Maturity Date,” which is a date that is 91 days prior to the stated maturity of either (i) the Company’s unsecured senior notes or (ii) the term B loans then outstanding if, on such 91st day, the applicable senior notes or term B loans remain outstanding and liquidity is less than (x) $250 million plus (y) the aggregate outstanding principal amount of such notes or term B loans, as applicable. Under Amendment No. 5, the outstanding New Term B-2 Loans were replaced with an equal amount of new term loans (the “New Term B-3 Loans”) having substantially similar terms as the New Term B-2 Loans, except with respect to the interest rate applicable to the New Term B-3 Loans and certain other provisions. As further amended, the New Term B-3 Loans bear interest at a SOFR-based rate (subject to a 0.50% floor) plus 1.75% as of March 31, 2026. The New Term B-3 Loans will mature on July 1, 2029.

Debt extinguishment costs related to the termination of the Existing Term Loans of $3 million were expensed in Other expense (income), net in the Condensed Consolidated Statement of Earnings during the nine months ended March 31, 2026.

In relation to the Term Facilities, the Company incurred interest expense, including amortization of debt issuance costs and the benefit of the interest rate cap and swap, of $32 million and $111 million in the three and nine months ended March 31, 2026, respectively, and $44 million and $150 million in the three and nine months ended March 31, 2025, respectively, which is included in Interest expense in the Condensed Consolidated Statements of Earnings (Loss).

On July 1, 2023, our interest rate cap became effective, which, together with our interest rate swap (through September 30, 2024), reduced interest expense by $3 million and $14 million during the three and nine months ended March 31, 2026, respectively, and $6 million and $27 million in the three and nine months ended March 31, 2025, respectively. The amortization of debt issuance costs included in interest expense was $3 million and $14 million in the three and nine months ended March 31, 2026, respectively, and $5 million and $14 million in the three and nine months ended March 31, 2025, respectively. Debt issuance costs are presented as a reduction of long-term debt in the Condensed Consolidated Balance Sheets.

As of March 31, 2026, the Company was in compliance with all covenants under the Senior Credit Facilities.

14

The Company had aggregate availability of $668 million under its Revolving Credit Facility as of March 31, 2026.

Debt Assumed through Acquisition

We assumed the remaining balances of three term loans with the closing of the acquisition of Coherent, Inc., two of which were repaid prior to June 30, 2024. The aggregate principal amount outstanding under the remaining assumed term loan is $15 million as of March 31, 2026 and is for a Facility Construction Loan in Germany due in 2030 that bears interest at 1.55% per annum. Payments are made quarterly.

5.000% Senior Notes due 2029

On December 10, 2021, the Company issued $990 million aggregate principal amount of Senior Notes pursuant to the indenture, dated as of December 10, 2021 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee. The Senior Notes are guaranteed by each of the Company’s domestic subsidiaries that guarantee its obligations under the Senior Credit Facilities. Interest on the Senior Notes is payable on December 15 and June 15 of each year, commencing on June 15, 2022, at a rate of 5.000% per annum. The Senior Notes will mature on December 15, 2029.

Beginning December 15, 2024, the Company may redeem the Senior Notes, in whole at any time or in part from time to time, at the redemption prices set forth in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. In addition, at any time prior to December 15, 2024, the Company had the ability to (but did not) redeem the Senior Notes, at its option, in whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount of the Senior Notes redeemed, plus a “make-whole” premium set forth in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. Notwithstanding the foregoing, prior to December 15, 2024, the Company had the ability to redeem up to 40% of the aggregate principal amount of the Senior Notes using the proceeds of certain equity offerings as set forth in the Indenture, at a redemption price equal to 105.000% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. The Company did not exercise this option.

In relation to the Senior Notes, the Company incurred interest expense of $13 million and $38 million in each of the three and nine months ended March 31, 2026 and March 31, 2025, which is included in Interest expense in the Condensed Consolidated Statements of Earnings (Loss).

The Indenture contains customary covenants and events of default, including default relating to, among other things, payment default, failure to comply with covenants or agreements contained in the Indenture or the Senior Notes and certain provisions related to bankruptcy events. As of March 31, 2026, the Company was in compliance with all covenants under the Indenture.

Note 9.    Leases

We determine if an arrangement is a lease at inception for arrangements with an initial term of more than 12 months, and classify it as either finance or operating.

Finance leases are generally those that allow us to substantially utilize or pay for the entire asset over its estimated useful life. Finance lease assets are recorded in Property, plant and equipment, net, and finance lease liabilities within Other accrued liabilities and Other liabilities on our Condensed Consolidated Balance Sheets. Finance lease assets are amortized in operating expenses on a straight-line basis over the shorter of the estimated useful lives of the assets or the lease term, with the interest component for lease liabilities included in interest expense and recognized using the effective interest method over the lease term.

Operating leases are leases that do not qualify as finance leases and are recorded in Other assets and Operating lease current liabilities and Operating lease liabilities on our Condensed Consolidated Balance Sheets. Operating lease assets are amortized on a straight-line basis in operating expenses over the lease term.

Our lease liabilities are recognized based on the present value of the remaining fixed lease payments, over the lease term, using a discount rate of similarly secured borrowings available to the Company. For the purpose of lease liability measurement, we consider only payments that are fixed and determinable at the time of commencement. Any variable payments that depend on an index or rate are expensed as incurred. We account for non-lease components, such as common area maintenance, as a component of the lease, and include it in the initial measurement of our leased assets and corresponding liabilities. Our lease terms and conditions may include options to extend or terminate. An option is recognized when it is reasonably certain that we will exercise that option.

Our lease assets also include any lease payments made, and exclude any lease incentives received prior to commencement. Our lease assets are tested for impairment in the same manner as long-lived assets used in operations.

15

The following table presents lease costs, which include leases for arrangements with an initial term of more than 12 months, remaining lease terms, and discount rates ($000):

Note 10.     Restructuring Plans

2023 Restructuring Plan

On May 23, 2023, the Board of Directors approved the 2023 Plan which includes site consolidations, facilities moves and closures, as well as the relocation and requalification of certain manufacturing facilities. These restructuring actions were intended to realign our cost structure as part of a transformation to a simpler, more streamlined, resilient and sustainable business model. We evaluate restructuring charges in accordance with ASC 420, Exit or Disposal Cost Obligations (“ASC 420”), and ASC 712, Compensation-Nonretirement Post-Employment Benefits (“ASC 712”).

In the three months ended March 31, 2026, these activities resulted in $4 million of net charges primarily for site closure and move costs and employee termination costs. In the nine months ended March 31, 2026, these activities resulted in $2 million of net recoveries primarily for adjustments to employee termination costs previously accrued partially offset by site move costs. In the three months ended March 31, 2025, these activities resulted in $11 million of net charges primarily for employee termination costs and site move costs. In the nine months ended March 31, 2025, these activities resulted in $43 million of net

16

charges primarily for impairment losses associated with the sale of our Newton Aycliffe business, employee termination costs, site move costs and accelerated depreciation.

Activity and accrual balances for the 2023 Plan were as follows for the first three quarters of fiscal 2026 and 2025 ($000):

At March 31, 2026, $7 million and $22 million of accrued severance related costs were included in other accrued liabilities and other liabilities on our Condensed Consolidated Balance Sheet, respectively, and are expected to result in cash expenditures through fiscal 2028. The current and prior year severance related net charges are primarily comprised of accruals and adjustments for severance and pay for employees being terminated due to the consolidation of certain manufacturing sites, with severance recorded in accordance with ASC 712.

For the three and nine months ended March 31, 2026 and March 31, 2025, restructuring costs were primarily incurred in the Datacenter & Communications segment. Restructuring charges (recoveries) are recorded in Restructuring charges in our Condensed Consolidated Statements of Earnings (Loss).

2025 Restructuring Plan

Commencing in the quarter ended March 31, 2025, and as part of the ongoing strategic review of the Company’s business, the Company’s management approved the 2025 Plan. In connection therewith, the Company incurs charges for related severance

17

and benefits, lease and contract termination costs, asset write-offs, facilities move and other restructuring costs. We evaluate restructuring charges in accordance with ASC 420 and ASC 712.

In the three and nine months ended March 31, 2026, these activities resulted in $31 million and $59 million, respectively, of net charges primarily related to write-off of property and equipment, employee termination and site closure costs. In the three months ended March 31, 2025, these activities resulted in $63 million of net charges primarily for the write-off of property and equipment and employee termination costs. We expect the restructuring actions to be substantially completed by the end of fiscal 2026. However, the actual timing and costs associated with these restructuring actions may differ from our current expectations and estimates and such differences may be material.

Activity and accrual balances for the 2025 Plan were as follows for the first three quarters of fiscal 2026 and 2025 ($000):

	Severance		Asset Write-Offs		Other		Total Accrual

At March 31, 2026, $26 million of accrued severance related costs were included in other accrued liabilities and are expected to result in cash expenditures primarily through fiscal 2026. The current year severance related net charges are primarily comprised of accruals for severance and pay for employees being terminated due to the consolidation of certain manufacturing and distribution sites as well as workforce reductions, with severance recorded in accordance with ASC 712. At March 31, 2026, total liabilities for asset write-offs and other contract costs of $10 million and $12 million were included in other accrued liabilities and other liabilities, respectively, on our Condensed Consolidated Balance Sheet.

The restructuring costs were incurred primarily in the Industrial segment for the three months ended March 31, 2026. For the nine months ended March 31, 2026, restructuring charges were incurred primarily in the Industrial and Corporate segments. For the three months ended March 31, 2025, restructuring charges were primarily incurred in the Industrial and Datacenter & Communications segments. Restructuring charges and recoveries are recorded in Restructuring charges in our Condensed Consolidated Statements of Earnings (Loss).

Note 11.        Contingencies

Regulatory Matters

In January 2025, the Company received an inquiry from the Bureau of Industry and Security (“BIS”) concerning past product sales to Huawei; the Company is cooperating with BIS’s inquiry and conducting an internal review of those sales to determine what products are subject to Export Administrative Regulations (“EAR”) and consequently restricted for export, reexport, and transfer when Huawei is a party to the transaction. The Company has stopped shipping products to Huawei. The Company is

18

currently in discussions with BIS regarding past product sales and cannot predict the outcome of those discussions. While the Company has received requests for additional information in this matter, the Company has not yet received any determination from BIS. In the event that the Company is found to have violated the EAR, the Company may be required to incur significant penalties and/or costs or expense as a result of the inquiry and to comply with, or remedy any violations of these regulations, but at this time, the Company is unable to determine an estimate or range of loss.

Note 12.    Equity and Redeemable Preferred Stock

Common shares issued

On March 2, 2026, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with NVIDIA Corporation (“NVIDIA”), pursuant to which the Company issued and sold 7,788,161 shares of Common Stock at a price of $256.80 per share, for aggregate gross proceeds of $2 billion. The transaction was completed as a private placement in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended. NVIDIA’s investment will support research and development initiatives, future capacity expansion, and operational capabilities, as Coherent expands its manufacturing footprint.

The shares issued to NVIDIA are subject to a contractual lock-up for a period of six months following the closing date, during which NVIDIA may not, without the Company’s prior written consent, directly or indirectly transfer or otherwise dispose of the shares or enter into transactions that transfer the economic risks or benefits of ownership.

The Purchase Agreement includes a price protection provision that is effective for a period of six months following execution of the Purchase Agreement. The Company evaluated the price protection provision under applicable U.S. GAAP, including ASC 815, Derivatives and Hedging, and ASC 480, Distinguishing Liabilities from Equity, and determined that the provision is indexed to the Company’s own stock and meets the criteria for equity classification. Accordingly, the price protection provision is not accounted for as a derivative liability and no separate fair value measurement is required subsequent to issuance. Any potential issuance of additional shares or cash settlement pursuant to the price protection provision, if triggered, will be accounted for as an adjustment to equity.

Preferred stock

As of March 31, 2026, the Company’s amended and restated articles of incorporation authorize the Board of Directors, without shareholder approvals, to issue up to 5 million shares of preferred stock. As of that date, 2.3 million shares of mandatory convertible preferred shares had been previously issued and subsequently converted into shares of the Company’s Common Stock. During the quarter ended December 31, 2025, 75,000 shares and 140,000 shares of previously issued Series B-1 (“Series B-1 Preferred Stock”) and B-2 convertible preferred stock (“Series B-2 Preferred Stock” and, together with the Series B-1 Preferred Stock, the “Series B Preferred Stock”), no par value per share, respectively, were converted into an aggregate of 30.1 million shares of Common Stock. The majority of the Series B-1 and B-2 convertible preferred stock was converted by the holder and the remainder was converted by the Company. No Series B convertible preferred stock was outstanding at March 31, 2026. As a result of the conversion, $2.5 billion was reclassified from Mezzanine Equity to Common Stock during the quarter ended December 31, 2025.

Series B Convertible Preferred Stock - Prior to Conversion in the quarter ended December 31, 2025

In March 2021, the Company issued 75,000 shares of Series B-1 Preferred Stock for $10,000 per share, resulting in an aggregate purchase price of $750 million. On July 1, 2022, the Company issued 140,000 shares of Series B-2 Preferred Stock for $10,000 per share and an aggregate purchase price of $1.4 billion.

The shares of Series B Preferred Stock were convertible into shares of Coherent Common Stock as follows:

•at the election of the holder, each share of Series B Preferred Stock could have been converted into shares of Coherent Common Stock at a conversion price of $85 per share (as it may be adjusted from time to time, the “Conversion Price”); and

•at the election of the Company at the then-applicable Conversion Price if the volume-weighted average price of Coherent Common Stock exceeded 150% of the then-applicable Conversion Price for 20 trading days out of any 30 consecutive trading days.

The issued shares of Series B Preferred Stock had voting rights, voting as one class with the Coherent Common Stock, on an as-converted basis, subject to limited exceptions.

The Series B Preferred Stock was initially measured at fair value less issuance costs, accreted to its redemption value over a 10-year period (using the effective interest method) with such accretion accounted for as deemed dividends and reductions to Net Earnings (Loss) Available to Common Shareholders.

19

Preferred stock dividends are presented as a reduction to Retained earnings on the Condensed Consolidated Balance Sheets. The Company entered into an agreement with the holder of the Series B Preferred Stock to waive dividends effective November 20, 2025. Due to the conversion of the Series B Preferred Stock to Common Stock in the quarter ended December 31, 2025, no dividends were declared or paid for the quarters ended December 31, 2025 or March 31, 2026.

The following table presents dividends per share and dividends recognized:

Note 13.    Noncontrolling Interests

On December 4, 2023, Silicon Carbide LLC (“Silicon Carbide”), one of the Company’s subsidiaries, completed (i) the sale of 16,666,667 Class A Common Units to Denso Corporation (“Denso”) for $500,000,000 pursuant to an Investment Agreement, dated as of October 10, 2023, by and between Silicon Carbide and Denso and (ii) the sale of 16,666,667 Class A Common Units to Mitsubishi Electric Corporation (“MELCO”) for $500,000,000 pursuant to an Investment Agreement, dated as of October 10, 2023, by and between Silicon Carbide and MELCO (collectively, the “Equity Investments”).

As a result of the Equity Investments, the Company’s ownership interest in the Class A Common units of Silicon Carbide LLC was reduced to approximately 75%. Denso and MELCO each own approximately 12.5% of the Class A Common Units of Silicon Carbide.

The Equity Investments in Silicon Carbide enables Coherent to increase its available free cash flow to provide greater financial and operational flexibility to execute its capital allocation priorities, as the aggregate $1 billion investment, net of transaction costs, is being and will continue to be used to fund future capital expansion of Silicon Carbide.

The following table presents the activity in noncontrolling interests in Silicon Carbide ($000):

Stock Award Plans

The Company grants equity awards pursuant to the Coherent Corp. Omnibus Incentive Plan (as amended and restated, the “Plan”). The Plan was originally approved by the Company’s shareholders at the Annual Meeting in November 2018, and was subsequently amended, restated and approved by the Company’s shareholders at the Annual Meetings held in November 2020, November 2023 and November 2024. The Plan provides for the grant of stock options, stock appreciation rights, restricted shares, restricted share units, deferred shares, performance shares and performance units to employees (including officers), consultants and directors of the Company.

The Company has an Employee Stock Purchase Plan whereby eligible employees may authorize payroll deductions (subject to certain limitations) of up to 15% (or such lesser amount as may be determined by the plan administrator) of their wages and base salary to purchase shares at an amount which will not be less than 85% of the lower of (i) the fair market value of the common stock on the first trading day of the offering period and (ii) the fair market value of the common stock on the last trading day of the approximately six-month offering period.

Share-based compensation expense for the periods indicated was as follows ($000):

Note 16.    Income Taxes

The Company’s fiscal year-to-date effective income tax rate was 3% at March 31, 2026 compared to 19% for the same period in the prior fiscal year. The variance from the U.S. statutory federal income tax rate of 21% was primarily driven by differences between U.S. and foreign tax rates, as well as discrete tax benefits related to changes in German tax law, releases of uncertain tax positions, and excess tax benefits associated with stock-based compensation.

U.S. GAAP prescribes the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements which includes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As of March 31, 2026 and June 30, 2025, the Company’s gross unrecognized tax benefit, excluding interest and penalties, was $68 million and $124 million, respectively. The Company has classified the uncertain tax positions as non-current income tax liabilities, as the amounts are not expected to be paid within one year. Due to the U.S. valuation allowance, a large portion of the gross unrecognized tax benefit will not impact the tax rate if recognized. As of March 31, 2026, $6 million of the gross unrecognized tax benefit would impact the effective tax rate if recognized. The Company recognizes interest and penalties related to uncertain tax positions in the income tax provision in the Condensed Consolidated Statements of Earnings (Loss). The amount of accrued interest and penalties included in the gross unrecognized income tax benefit was $7 million and $9 million at March 31, 2026 and June 30, 2025, respectively.

Fiscal years 2022 to 2025 remain open to examination by the Internal Revenue Service, fiscal years 2021 to 2025 remain open to examination by certain state jurisdictions, and fiscal years 2012 to 2025 remain open to examination by certain foreign taxing jurisdictions. The Company is currently under examination by the Internal Revenue Service for the fiscal year ended June 30, 2024, New York City for the years ended June 30, 2023 through June 30, 2024; New York for the years ended June 30, 2023 through June 30, 2024; Massachusetts for the year ended June 30, 2023 and for certain subsidiary companies in Vietnam for the years ended June 30, 2017 through September 30, 2021; Malaysia for the years ended June 30, 2021 through June 30, 2023; Singapore for the year ended June 30, 2023; United Kingdom for the years ended June 30, 2022 through June 30, 2023; and Germany for the years ended September 30, 2012 through June 30, 2021. The Company believes its income tax reserves for these tax matters are adequate.

Note 17.    Earnings Per Share

Basic earnings per common share is computed by dividing net earnings available to the common shareholders by the weighted-average number of shares of common stock outstanding during the period.

21

Diluted earnings per common share is computed by dividing the diluted earnings available to the common shareholders by the weighted-average number of shares of common stock and potentially dilutive shares of common stock outstanding during the period. Potentially dilutive shares whose effect would have been anti-dilutive are excluded from the computation of diluted earnings per common share.

The dilutive effect of equity awards is calculated based on the average stock price for each fiscal period, using the treasury stock method. For the three and nine months ended March 31, 2026 and the nine months ended March 31, 2025, diluted shares outstanding include the dilutive effect of the potential shares of Coherent Common Stock issuable from performance and restricted shares. For the three months ended March 31, 2025, as the Company was in a net loss position, there were no dilutive shares.

For the nine months ended March 31, 2026, diluted earnings per share included the potentially dilutive effect of the shares of Coherent Common Stock issuable upon conversion of the Series B Convertible Preferred Stock, calculated using the If-Converted method through their respective conversion dates, as the effect was dilutive. For the three months ended March 31, 2025, diluted loss per share excluded the shares of Coherent Common Stock issuable upon conversion of the Series B Convertible Preferred Stock under the If-Converted method, as the effect was anti-dilutive. For the nine months ended March 31, 2025, diluted earnings per share likewise excluded the potentially dilutive effect of such shares, as the effect was anti-dilutive.

The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations (000, except per share data):

Note 18.    Segment Reporting

The Company’s businesses are organized and managed into segments based on similarities in products and services. Segment determination reflects how the CODM evaluates the Company’s operations for decision-making operating decisions and performance assessment. Effective July 1, 2025, the Company realigned its organizational structure and now identifies multiple operating segments, which are aggregated into two reportable segments: (i) Datacenter & Communications, and (ii) Industrial. In accordance with ASC 280, Segment Reporting, the aggregation of the Company’s segments is based on similarities in economic characteristics, product and service types, production processes, type or class of customers, and distribution methods. Previously, financial results had been reported in the following three segments: (i) Networking, (ii) Materials, and (iii) Lasers. Comparative prior period segment information has been recast to conform to the new segments.

The Datacenter & Communications segment has locations in the United States, Australia, China, Germany, Malaysia, South Korea, Sweden, Switzerland, Thailand, the Philippines and Vietnam. This segment sells primarily into the datacenter and communications market, including transceivers, systems, subsystems, modules, components, optics, and semiconductor devices.

The Industrial segment has locations in the United States, China, Finland, Germany, Italy, Japan, Malaysia, Singapore, South Korea, Spain, Sweden, Taiwan, the Philippines, the United Kingdom and Vietnam. This segment sells primarily into the industrial market, which includes lasers, systems, optics, components and materials for semiconductor and display capital equipment, precision manufacturing, life sciences, consumer electronics, scientific research and automotive and market applications.

Our CODM receives and reviews financial information based on the operating segments that are aggregated into the two reportable segments. Our CODM evaluates each segment’s performance and allocates resources based on segment revenue and segment profit, as our CODM believes segment profit is a more comprehensive profitability measure for each operating segment. Our CODM is regularly provided with segment revenue and segment profit information to assess performance of each segment. Segment profit includes operating expenses directly managed by operating segments, including research and development, direct sales, marketing and administrative expenses. Segment profit does not include share-based compensation, acquisition or integration related costs, amortization and impairment of acquisition-related intangible assets, restructuring charges, impairment charges on assets held-for-sale, gain on sale of businesses and certain other charges or gains. Additionally, we do not allocate Corporate strategic research and development, strategic marketing and sales expenses and shared general and administrative expenses, as these expenses are not directly attributable to our operating segments. The segments are managed separately due to the unique products and markets that each serves. The Company derives its reportable segment results based on how financial information is reported and aggregated within its management reporting system. The CODM uses segment profit as a key metric in the forecasting process and in making decisions related to capital allocation and resource deployment across segments. The accounting policies are consistent across each segment. Assets by segment are not a measure used to assess the performance of the company by the CODM and thus are not reported in our disclosures.

The following table summarizes selected financial information of our operations by segment and reconciles segment profit to consolidated earnings (loss) before income taxes for the periods presented ($000):

Note 19.    Fair Value of Financial Instruments

The FASB defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous markets for the asset and liability in an orderly transaction between market participants at the measurement date. We estimate fair value of our financial instruments utilizing an established three-level hierarchy in accordance with U.S. GAAP. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date as follows:

•Level 1 – Valuation is based upon unadjusted quoted prices for identical assets or liabilities in active markets.

•Level 2 – Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instruments.

•Level 3 – Valuation is based upon other unobservable inputs that are significant to the fair value measurements.

The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement.

On February 23, 2022, we entered into an interest rate cap (the “Cap”) with an effective date of July 1, 2023. On March 20, 2023, we amended the Cap to replace the current reference rate (LIBOR) with SOFR, to be consistent with Amendment No. 1 to the Credit Agreement. See Note 8. Debt for further information. The Cap manages our exposure to interest rate movements on a portion of our floating rate debt. The Cap provides us with the right to receive payment if one-month SOFR exceeds 1.92%. Beginning in July 2023, we began to pay a fixed monthly premium based on an annual rate of 0.853% for the Cap. On September 1, 2024, we increased the notional amount from $500 million to $1,500 million. The fair value of the interest rate cap of $6 million and $17 million is recognized in the Condensed Consolidated Balance Sheet within Prepaid and other current assets and Other assets as of March 31, 2026 and June 30, 2025, respectively.

The Cap, as amended, is designed to mirror the terms of the Credit Agreement as amended on March 31, 2023. We designated the Cap as a cash flow hedge of the variability of the SOFR based interest payments on the Term Facilities. Every period over the life of the hedging relationship, the entire change in fair value related to the hedging instrument will first be recorded within AOCI. Amounts accumulated in AOCI are reclassified into interest expense in the same period or periods in which interest expense is recognized on the Credit Agreement, or its direct replacement. The fair value of the Cap is determined using widely accepted valuation techniques and reflects the contractual terms of the Cap including the period to maturity, and while there are no quoted prices in active markets, it uses observable market-based inputs, including interest rate curves. The fair value analysis also considers a credit valuation adjustment to reflect nonperformance risk of both the Company and the single counterparty. The Cap is classified as a Level 2 item within the fair value hierarchy.

We estimated the fair value of the Senior Notes and the Term Facilities (“Debt Facilities”) based on quoted market prices as of the last trading day prior to March 31, 2026; however, the Debt Facilities have only a limited trading volume and as such this fair value estimate is not necessarily the value at which the Debt Facilities could be retired or transferred. We concluded that this fair value measurement should be categorized within Level 2. The carrying values of the Debt Facilities are net of unamortized discount and issuance costs. See Note 8. Debt for details on the Company’s Debt Facilities.

25

The fair value and carrying value of the Debt Facilities were as follows ($000):

	March 31, 2026				June 30, 2025
	Fair Value		Carrying Value		Fair Value		Carrying Value
Senior Notes	$	972,824	$	985,797	$	973,190	$	985,034
Term A Facility	1,144,902		1,134,543		632,960		616,234
Term B Facility	1,083,380		1,057,180		2,108,938		2,065,880

Our borrowings, including our lease obligations and the Debt Facilities, are considered Level 2 among the fair value hierarchy.

Cash and cash equivalents are considered Level 1 among the fair value hierarchy and approximate fair value because of the short-term maturity of those investments. At March 31, 2026, time deposits of $825 million, with maturities of one year or less, are recorded in Short-term investments on the Condensed Consolidated Balance Sheet are considered Level 1 among the fair value hierarchy and approximate fair value because of the short-term maturity of those investments.

At March 31, 2026, total restricted cash was $633 million, which includes $630 million held by Silicon Carbide LLC and restricted for use only by that subsidiary, and $3 million of cash restricted for other purposes in other entities. At June 30, 2025, total restricted cash was $724 million, which includes $720 million of cash held by Silicon Carbide LLC and restricted for use only by that subsidiary, and $4 million of cash restricted for other purposes in other entities. The restricted cash is invested in money market accounts and time deposits, with maturities of one year or less, that are held-to-maturity, are considered Level 1 among the fair value hierarchy and approximate fair value. Restricted cash that is expected to be spent and released from restriction after 12 months is classified as non-current on the Condensed Consolidated Balance Sheets.

We, from time to time, purchase foreign currency forward exchange contracts that permit us to sell specified amounts of these foreign currencies for pre-established U.S. dollar amounts at specified dates that represent assets or liabilities on the balance sheets of certain subsidiaries. These contracts are entered into for the purpose of limiting translational exposure to changes in currency exchange rates and which otherwise would expose our earnings, on the revaluation of our aggregate net assets or liabilities in respective currencies, to foreign currency risk. At March 31, 2026, we had no foreign currency forward contracts. The fair values of these instruments, when outstanding, are measured using valuations based upon quoted prices for similar assets and liabilities in active markets (Level 2) and are valued by reference to similar financial instruments, adjusted for credit risk and restrictions and other terms specific to the contracts. Realized gains related to these contracts for the three and nine months ended March 31, 2026 were zero and realized gains related to these contracts for the three and nine months ended March 31, 2025 were zero and $16 million, respectively, and were included in Other income, net in the Condensed Consolidated Statements of Earnings (Loss).

Overview

Coherent Corp. (“Coherent”, the “Company,” “we,” “us” or “our”) is a vertically integrated manufacturing company that develops, manufactures and markets lasers, transceivers, and other optical and optoelectronic devices, modules, and systems, as well as engineered materials, for use in communications, industrial, instrumentation and electronics applications. We generate nearly all of our revenues, earnings, and cash flows from developing, manufacturing, and marketing a wide range of products and services for our end markets. Coherent has broad technical expertise and a deep technology stack in areas of importance to our products, including materials growth and fabrication of specialty materials, semiconductor lasers, passive optics including isolators, transceivers, transport equipment, high power lasers for semiconductor capital equipment, display manufacturing, precision manufacturing, and scientific research. Many of our products include custom integrated software that we develop internally, leveraging our deep domain expertise. Headquartered in Saxonburg, Pennsylvania, Coherent has research and development, manufacturing, sales, service, and distribution facilities worldwide.

Trends and Other Matters Affecting Our Business

Industry Conditions

Coherent is a global leader in photonic technology, which is foundational to the performance and scalability of AI datacenters and critical to many important industrial applications. We are at the center of a significant expansion in optical networking infrastructure, driven by the rapid growth of AI and the increasing need for bandwidth and energy efficiency. We continue to experience strong demand in our Datacenter and Communications markets. The increasing investments by hyperscale and other cloud providers in AI datacenter infrastructures have significantly boosted demand for our datacenter transceivers. Elevated demand for our new ZR/ZR+ transceivers and sustained growth in traditional telecom transport products drove higher shipment volumes for our telecom and other communications solutions. We are investing in manufacturing capacity for the Datacenter and Communications markets, including expanding our indium phosphide capacity in Sherman, Texas, to address our increased customer demand and industry-wide shortage. In our Industrial markets, we are experiencing strong demand in semiconductor capital equipment.

Agreements with NVIDIA

On March 2, 2026, the Company entered into a multi-year strategic agreement with NVIDIA to advance the development of advanced optics technologies, including manufacturing capacity and research and development, to enable next-generation AI infrastructure. The non-exclusive agreement includes a multi-billion-dollar purchase commitment with NVIDIA, as well as future access and capacity rights for advanced laser and optical networking products. Separately, on March 2, 2026, NVIDIA made a $2 billion investment in the Company, through the purchase of shares of the Company’s Common Stock in a private placement. The proceeds from the investment will be used to support research and development, future capacity and operations as we build out our manufacturing capabilities. See Note 12. Equity and Redeemable Preferred Stock for further information.

Change in Reportable Segments

Operating segments are defined as components of a company that engage in business activities from which they may earn revenues and incur expenses, and for which discrete financial information is available and is evaluated regularly by the CODM in deciding how to allocate resources and in assessing performance. Aggregation of similar operating segments into reportable operating segments is permitted if the businesses have similar economic characteristics and meet established qualitative criteria. Effective July 1, 2025, we realigned our organizational structure and identified multiple operating segments which have been aggregated into two reportable segments based on our internal management structure and CODM oversight: (i) Datacenter & Communications, and (ii) Industrial. See Note 18. Segment Reporting for further information.

Restructuring Plans

2023 Plan

On May 23, 2023, the Board of Directors approved the 2023 Plan which includes site consolidations, facilities moves and closures, as well as the relocation and requalification of certain manufacturing facilities. These restructuring actions were intended to realign our cost structure as part of a transformation to a simpler, more streamlined, resilient and sustainable business model.

In the three and nine months ended March 31, 2026, these activities resulted in net charges of $4 million and net recoveries of $2 million, respectively. The current quarter charges are primarily for site closure and move costs and employee termination costs and the current year-to-date recoveries are primarily for adjustments to employee termination costs partially offset by site move costs. In fiscal 2025, these activities resulted in charges of $53 million, primarily for impairment losses associated with the sale of our Newton Aycliffe business, impairment of right-of-use (“ROU”) assets, employee termination costs, site move costs and accelerated depreciation. In fiscal 2024, these activities resulted in $119 million of charges primarily for employee

28

termination costs, and the write-off of property and equipment, net of $65 million from reimbursement arrangements. See Note 10. Restructuring Plans for further information.

2025 Plan

Commencing in the quarter ended March 31, 2025, and as part of the ongoing strategic review of the Company’s business, the Company’s management approved the 2025 Plan to take a number of restructuring actions, including site consolidations, facilities moves and closures, workforce reductions, contract terminations, and certain other associated cost reductions. The 2023 Plan and the 2025 Plan are collectively referred to as the “Restructuring Plans.”

In the three and nine months ended March 31, 2026, these activities resulted in $31 million and $59 million, respectively, of charges primarily related to write-off of property and equipment, employee termination and site closure costs. In fiscal 2025, these activities resulted in $107 million of charges primarily for the write-off of property and equipment and ROU assets, employee and contract termination costs. We expect the restructuring actions to be substantially completed by the end of fiscal 2026. However, the actual timing and costs associated with these restructuring actions may differ from our current expectations and estimates and such differences may be material. See Note 10. Restructuring Plans for further information.

Impairment of Assets Held-for-Sale and Sale of Business

In the fourth quarter of fiscal 2025, management entered into non-binding agreements to sell several entities. As a result of classifying these entities as held-for-sale, we recorded non-cash impairment charges of $85 million within the Industrial segment. These charges were recognized in Impairment of assets held-for-sale in our Consolidated Statements of Earnings (Loss) for the fourth quarter of fiscal 2025 to reduce the carrying values of the entities to their estimated fair value. In the nine months ended March 31, 2026, we recorded additional non-cash impairment charges of $20 million, within the Industrial segment. The charges were recorded in Impairment of assets held-for-sale in the Condensed Consolidated Statements of Earnings (Loss) to reduce the carrying values of the entities that continue to meet the held-for-sale criteria to their estimated fair value.

On September 2, 2025, we completed the sale of our aerospace and defense business, which is part of our Industrial segment, for approximately $400 million and recorded a gain of $115 million to Gain on sale of business in our Condensed Consolidated Statements of Earnings (Loss) for the first quarter of fiscal 2026.

On January 30, 2026, the Company completed the sale of its product division based in Munich, Germany and recorded a gain of $9 million within Gain on sale of business in the Condensed Consolidated Statements of Earnings (Loss) for the third quarter of fiscal 2026. The total loss associated with the sale was $96 million, substantially all of which was recognized through impairment charges within Impairment of assets held-for-sale in the Condensed Consolidated Statements of Earnings (Loss), including $81 million in the fourth quarter of fiscal 2025, $13 million in the first quarter of fiscal 2026 and $11 million in the second quarter of fiscal 2026.

See Note 7. Assets Held-for-Sale and Sale of Business for further information.

Macroeconomic Conditions - Tariffs and Export Controls

In early 2025, the United States implemented significant new tariffs and export restrictions affecting a broad range of countries, commodities and industries. These actions have prompted retaliatory measures from certain foreign governments, including the imposition of tariffs and export controls. On February 20, 2026, the U.S. Supreme Court ruled that tariffs imposed under the International Emergency Economic Powers Act (“EEPA”) were not authorized by the statute. The Company is the importer of record for certain raw materials and products that were previously subject to such tariffs under IEEPA. Significant uncertainty remains regarding how and when any amounts may be recovered. We are evaluating the ruling and potential actions available to us. Because the process, timing, and amount of any recovery are uncertain, we have not recorded any potential benefit from a refund at this time.

These tariffs and export restrictions did not have a material impact on our business, financial condition, operational results and/or cash flows in the third quarter of fiscal 2026.

As a global company with a substantial and diversified manufacturing footprint, this footprint provides us with some insulation against these tariffs, trade sanctions, and other geopolitical challenges. Our geographically diverse supply chain combined with the internal production of many of our most critical technological in-feeds provides adaptability and optionality that benefits our customers. As the tariff, trade sanctions, and export restrictions become clearer, we expect to identify opportunities to mitigate their impact. However, we operate in a dynamic geopolitical environment, and we are not immune to any sustained disruption in global trade conditions. Such disruptions could create future headwinds for the Company and may result in revenue reduction, cost increases on material used in our products or significant production delays, which could adversely affect our business, financial condition, results of operations and cash flows.

29

Critical Accounting Estimates

The preparation of financial statements and related disclosures are in conformity with accounting principles generally accepted in the United States of America and the Company’s discussion and analysis of its financial condition and results of operations require the Company’s management to make judgments, assumptions and estimates that affect the amounts reported in its Condensed Consolidated Financial Statements and accompanying notes.

Note 1 of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025 describes the significant accounting policies and methods used in the preparation of the Company’s consolidated financial statements.

New Accounting Standards

See Note 2. Recently Issued Financial Accounting Standards for a description of recent accounting pronouncements, including the expected dates of adoption and estimated effects, if any, on our consolidated financial statements.

Conversion of Series B Preferred Stock

All outstanding shares of Series B-1 and Series B-2 Preferred Stock were converted to Company Common Stock in the second quarter of fiscal 2026, and no shares of Preferred Stock are currently issued and outstanding. See Note 12. Equity and Redeemable Preferred Stock for further information.

Consolidated

Revenues. Revenues for the three months ended March 31, 2026 increased 21% to $1,806 million, compared to $1,498 million for the same period last fiscal year. Revenues increased $393 million, or 41%, in the Datacenter & Communications segment. Revenue growth in our Datacenter business was fueled by continued strong AI datacenter demand, while our Communications business benefited from increased demand in data center interconnect, scale across and traditional telecom applications. In the Industrial segment, revenue decreased $85 million, or 16%, primarily due to the divestitures of our aerospace and defense business on September 2, 2025 and our Munich, Germany business on January 30, 2026.

Revenues for the nine months ended March 31, 2026 increased 19% to $5,073 million, compared to $4,281 million for the same period last fiscal year. Revenues increased $923 million, or 34%, in the Datacenter & Communications segment. Revenue growth in our Datacenter business was fueled by continued strong AI datacenter demand, while our Communications business benefited from increased demand in data center interconnect, scale across and traditional telecom applications. In the Industrial segment, revenue decreased $131 million, or 8%, primarily due to the divestitures of our aerospace and defense business on September 2, 2025 and our Munich, Germany business on January 30, 2026.

Gross margin. Gross margin for the three months ended March 31, 2026 was $680 million, or 38% of revenues, compared to $528 million, or 35% of revenues, for the same period in the prior fiscal year, representing an increase of 243 basis points. The improvement in gross margin percentage was primarily driven by higher revenue volume, cost reductions in product input costs and efficiency gains from improved cycle times in the manufacturing process and yield improvements within the Datacenter & Communications segment. Gross margin also benefited from pricing optimization in the Datacenter & Communications segment, as well as the divestitures of our aerospace and defense business on September 2, 2025 and our Munich, Germany business on January 30, 2026. Gross margin for the nine months ended March 31, 2026 was $1,882 million, or 37% of revenues, compared to $1,497 million, or 35% of revenues, for the same period in the prior year, representing an increase of 213 basis points. The increase was primarily driven by cost reductions in product input costs, efficiency gains from improved cycle times in the manufacturing process and yield improvements in the Datacenter & Communications segment. In addition, gross margin benefited from pricing optimization in both the Datacenter & Communications and Industrial segments and the divestitures of our aerospace and defense business on September 2, 2025 and our Munich, Germany business on January 30, 2026.

31

Research and development. Research and development (“R&D”) expenses for the three months ended March 31, 2026 were $186 million, or 10% of revenues, compared to $151 million, or 10% of revenues, for the same period last fiscal year. R&D expenses for the nine months ended March 31, 2026 were $507 million, or 10% of revenues, compared to $426 million, or 10% of revenues, for the same period last fiscal year. The increases in R&D expenses were primarily related to continued investment in our product portfolios, particularly in our Datacenter & Communications segment. We continue to prioritize R&D investments in projects with the highest expected return-on-investment, supporting our long-term growth strategy.

Selling, general and administrative. Selling, general and administrative (“SG&A”) expenses for the three months ended March 31, 2026 were $268 million, or 15% of revenues, compared to $231 million, or 15% of revenues, for the same period last fiscal year. SG&A expenses for the nine months ended March 31, 2026 were $778 million, or 15% of revenues, compared to $681 million, or 16% of revenues, for the same period last fiscal year. Although flat for the three months ended March 31, 2026 and slightly decreased for the nine months ended March 31, 2026 as a percentage of revenue, the increases in SG&A expenses in both periods were primarily driven by higher legal, integration and divestiture-related consulting costs, higher facility exit costs and higher share-based compensation expense, partially offset by efficiencies achieved from cost reduction initiatives.

Restructuring charges. Restructuring charges for the three and nine months ended March 31, 2026 were $34 million and $57 million, respectively, and consisted primarily of employee termination costs, asset write-offs and move and other costs due to the consolidation and closure of certain manufacturing sites. Restructuring charges for the three and nine months ended March 31, 2025 were $74 million and $106 million, respectively, and consisted of asset write-offs, employee termination costs, move costs and accelerated depreciation due to the consolidation of certain manufacturing sites as well as impairment losses associated with the sale of our Newton Aycliffe business. See Note 10. Restructuring Plans for further information.

Impairment of assets held-for-sale. Impairment of assets held-for-sale for the nine months ended March 31, 2026 was $20 million, and represented non-cash impairment charges to reduce our carrying value in entities that continue to meet the held-for-sale criteria at December 31, 2025 to their estimated fair value. See Note 7. Assets Held-for-Sale and Sale of Business for further information.

Gain on sale of business. Gain on sale of business for the three and nine months ended March 31, 2026 was $9 million and $124 million, respectively, and relates to the sales of our aerospace and defense and our Munich, Germany businesses. See Note 7. Assets Held-for-Sale and Sale of Business for further information.

Interest and other, net. Interest and other, net expense for the three months ended March 31, 2026 was $16 million, compared to $62 million for the same period in the prior fiscal year, representing a decrease of $45 million. Included in Interest and other, net, were interest expense on borrowings, foreign currency gains and losses, amortization of debt issuance costs, equity gains and losses from unconsolidated investments, and interest and dividend income on cash balances. For the three months ended March 31, 2026, the decrease of $45 million in comparison to the same period last fiscal year was driven by $16 million lower foreign exchange net losses, $14 million gains on sales from an equity investment and $13 million lower interest expense. The $16 million lower foreign exchange net losses were primarily due to lower volatility of exchange rates during the three months ended March 31, 2026. The $13 million lower interest expense was primarily due to lower interest expense on our Term Loans resulting from lower balances and lower interest rates, partially offset by lower interest expense benefit from our interest rate cap. Interest and other, net expense for the nine months ended March 31, 2026 was $75 million, compared to $126 million for the same period in the prior fiscal year, a decrease of $52 million. Included in Interest and other, net, were interest expense on borrowings, foreign currency gains and losses, amortization of debt issuance costs, losses on debt extinguishment, equity gains and losses from unconsolidated investments, and interest and dividend income on cash balances. For the nine months ended March 31, 2026, the decrease of $52 million in comparison to the same period last fiscal year was driven by $39 million lower interest expense and $36 million gains on sale from an equity investment, partially offset by $10 million lower interest income, $6 million lower foreign exchange net gains and $5 million higher debt extinguishment and debt transaction fees. The $39 million lower interest expense was primarily due to lower interest expense on our Term Loans resulting from lower balances and lower interest rates partially offset by lower interest expense benefit from our interest rate cap and swap. The $10 million lower interest and dividend income was primarily due to decreases in interest rates earned on investments as well as the decrease in average cash and restricted cash balances. The $6 million lower foreign exchange net gains were primarily due to lower volatility of exchange rates during the nine months ended March 31, 2026.

Income taxes. The Company’s year-to-date effective income tax rate at March 31, 2026 was 3% compared to 19% for the same period in the prior fiscal year. The variance from the U.S. statutory federal income tax rate of 21% was primarily driven by differences between U.S. and foreign tax rates, as well as discrete tax benefits related to changes in German tax law, releases of uncertain tax positions, and excess tax benefits associated with stock-based compensation.

Net loss attributable to noncontrolling interests. Net loss attributable to noncontrolling interests for the three and nine months ended March 31, 2026 was $10 million and $14 million, respectively, compared to $14 million and $17 million, respectively, in the same periods in the prior fiscal year. This amount represents the noncontrolling interest holders’ shares of losses of Silicon Carbide LLC. See Note 13. Noncontrolling Interests for further information.

Segment Reporting

Revenues and segment profit for the Company’s reportable segments are discussed below. Our CODM evaluates each segment’s operations for decision-making and performance assessment based on segment revenue and segment profit, as our CODM believes segment profit is a more comprehensive profitability measure for each operating segment. Segment profit includes operating expenses directly managed by operating segments, including research and development, direct sales, marketing and administrative expenses. Segment profit does not include share-based compensation, acquisition or integration related costs, amortization and impairment of acquisition-related intangible assets, restructuring charges, impairment charges on assets held-for-sale, gain on sale of businesses and certain other charges. Additionally, we do not allocate Corporate strategic research and development, strategic marketing and sales expenses and shared general and administrative expenses, as these expenses are not directly attributable to our operating segments. Management believes segment profit to be a useful measure for investors, as it reflects the results of segment performance over which management has direct control and is used by management in its evaluation of segment performance. See Note 18. Segment Reporting for further information on the Company’s reportable segments and for the reconciliation of the Company’s segment profit to earnings (loss) before income taxes, which is incorporated herein by reference. Effective July 1, 2025, we report our financial results in the following two designated segments: (i) Datacenter & Communications and (ii) Industrial.

Comparative prior period segment information has been recast to conform to the new segments.

Datacenter & Communications ($ in millions)

	Three Months Ended March 31,				% Increase	Nine Months Ended March 31,				% Increase
	2026		2025			2026		2025
Revenues	$	1,362	$	969	41%	$	3,660	$	2,737	34%
Segment profit	$	348	$	233	49%	$	923	$	665	39%

Revenues for the three months ended March 31, 2026 increased 41% to $1,362 million, compared to $969 million for the same period in the prior fiscal year. Revenues for the nine months ended March 31, 2026 increased 34% to $3,660 million, compared to $2,737 million for the same period in the prior fiscal year. The increases in revenue of $393 million and $923 million during the three and nine months ended March 31, 2026, respectively, were primarily driven by growth in our Datacenter business reflecting continued strong AI datacenter demand as well as higher Communications business revenue due to increased demand for data center interconnect, scale across and traditional telecom applications.

Segment profit for the three months ended March 31, 2026 increased 49% to $348 million, compared to $233 million for the same period last fiscal year. Segment profit for the nine months ended March 31, 2026 increased 39% to $923 million, compared to $665 million for the same period last fiscal year. The increases in segment profit for the three and nine months ended March 31, 2026 were primarily driven by higher revenues, partially offset by increased R&D investments to support expansion of our product portfolio.

Industrial ($ in millions)

	Three Months Ended March 31,				% Increase (Decrease)	Nine Months Ended March 31,				% Increase (Decrease)
	2026		2025			2026		2025
Revenues	$	444	$	529	(16)%	$	1,413	$	1,544	(8)%
Segment profit	$	101	$	115	(12)%	$	329	$	300	10%

Revenues for the three months ended March 31, 2026 decreased 16% to $444 million, compared to $529 million for the same period in the prior fiscal year. Revenues for the nine months ended March 31, 2026 decreased 8% to $1,413 million, compared to $1,544 million for the same period in the prior fiscal year. The decreases in revenue of $85 million and $131 million during the three and nine months ended March 31, 2026, respectively, were primarily attributable to the divestitures of our aerospace and defense business on September 2, 2025 and our Munich, Germany business on January 30, 2026.

Segment profit for the three months ended March 31, 2026 decreased 12% to $101 million, compared to $115 million for the same period last fiscal year, primarily driven by the divestiture of our aerospace and defense business on September 2, 2025 and our Munich, Germany business on January 30, 2026 as well as increased R&D investments to support our product portfolio, partially offset by lower manufacturing and SG&A costs. Segment profit for the nine months ended March 31, 2026 increased 10% to $329 million, compared to $300 million for the same period last fiscal year. The increase was primarily driven by lower manufacturing costs, favorable product mix and improvements in pricing optimization as well as lower SG&A costs partially offset by increased R&D investments.

Liquidity and Capital Resources

Historically, our primary sources of cash have been provided from operations, long-term borrowings, and advance funding from customers. Other sources of cash include proceeds from the issuance of equity, proceeds received from the exercises of stock options, and sale of equity investments and businesses. Our historic uses of cash have been for business acquisitions, capital expenditures, investment in research and development, payments of principal and interest on outstanding debt obligations, payments of debt and equity issuance costs to obtain financing and payments in satisfaction of employees’ minimum tax obligations. Supplemental information pertaining to our sources and uses of cash for the periods indicated is presented as follows:

Sources (uses) of cash ($ in millions):

	Nine Months Ended March 31,
	2026		2025
Net cash provided by operating activities	$	10	$	503
Proceeds from issuance of common shares	2,000		—
Proceeds from exercises of stock options and purchases of stock under employee stock purchase plan	52		47
Effect of exchange rate changes on cash and cash equivalents and other items	(2)		3
Proceeds from long-term borrowings and revolving credit facilities	1,882		36
Payment of dividends	(11)		—
Debt issuance costs	(9)		—
Purchases of short-term investments	(825)		—
Proceeds from the sale of business	437		27
Proceeds from sale of equity investment	49		—
Other items	(4)		(2)
Payments in satisfaction of employees’ minimum tax obligations	(52)		(49)
Payments on borrowings under revolving credit facilities	(625)		(34)
Payments on existing debt	(1,762)		(386)
Additions to property, plant & equipment	(547)		(309)

Operating activities:

Net cash provided by operating activities was $10 million for the nine months ended March 31, 2026 compared to $503 million for the same period in the prior fiscal year. The decrease in cash flows provided by operating activities during the nine months ended March 31, 2026 compared to the same period in the prior fiscal year was primarily driven by a significant increase in inventories to support higher revenue levels, which resulted in increased working capital usage. This impact was partially offset by higher accounts payable and higher net earnings.

Investing activities:

Net cash used in investing activities was $891 million for the nine months ended March 31, 2026, compared to net cash used of $284 million for the same period in the prior fiscal year. The increase was primarily due to $825 million purchases of short-term investments and higher cash used to fund capital expenditures partially offset by $437 million cash received from the sale of businesses, net of fees, and cash received from the sale of an equity investment.

Financing activities:

Net cash provided by financing activities was $1,476 million for the nine months ended March 31, 2026, compared to net cash used of $386 million for the same period in the prior fiscal year. The increase was primarily due to the $2 billion in proceeds from the issuance of Common Stock to NVIDIA, net of fees, partially offset by higher payments, net of borrowings, on existing debt obligations.

34

Senior Credit Facilities

On September 26, 2025, the Company entered into Amendment No. 4 and Amendment No. 5 to the Credit Agreement. Under Amendment No. 4, (i) the existing revolving credit commitments were refinanced and replaced with the 2025 Revolving Loans, including the 2025 Incremental Term A Loans, the proceeds of which were used, in part, to repay all outstanding principal, interest and fees of the Existing Term A Loans. As amended, the 2025 Revolving Loans and the 2025 Incremental Term A Loans each bear interest at an adjusted SOFR rate subject to a 0.00% floor plus a range of 1.25% to 2.25% based on the Company’s total net leverage ratio. The interest rate applicable to the 2025 Revolving Loans and the 2025 Incremental Term A Loans is initially a SOFR-based rate plus 1.50% as of March 31, 2026. The 2025 Revolving Loans and the 2025 Incremental Term A Loans mature on the earlier of September 26, 2030 or a “Springing Maturity Date,” which is a date that is 91 days prior to the stated maturity of either (i) the Company’s unsecured senior notes or (ii) the term B loans then outstanding if, on such 91st day, the applicable senior notes or term B loans remain outstanding and liquidity is less than (x) $250 million plus (y) the aggregate outstanding principal amount of such notes or term B loans, as applicable. Under Amendment No. 5, the outstanding New Term B-2 Loans were replaced with the New Term B-3 Loans having substantially similar terms as the New Term B-2 Loans, except with respect to the interest rate applicable to the New Term B-3 Loans and certain other provisions. As further amended, the New Term B-3 Loans bear interest at a SOFR-based rate (subject to a 0.50% floor) plus 1.75% as of March 31, 2026. The New Term B-3 Loans will mature on July 1, 2029.

In relation to the Term Facilities, the Company incurred expense of $32 million and $111 million, respectively, for the three and nine months ended March 31, 2026, which is included in Interest expense in the Condensed Consolidated Statements of Earnings (Loss). On July 1, 2023, our interest rate cap became effective, which reduced interest expense by $3 million and $14 million, respectively, during the three and nine months ended March 31, 2026.

During the nine months ended March 31, 2026, the Company made payments of $509 million for the Term Facilities, $502 million of which were voluntary payments.

As of March 31, 2026, the Company had no borrowings outstanding under the Revolving Credit Facility.

Our cash position, borrowing capacity and debt obligations are as follows (in millions):

	March 31, 2026		June 30, 2025
Cash and cash equivalents	$	1,593	$	909
Restricted cash, current	42		9
Restricted cash, non-current	591		715
Short-term investments	825		—
Available borrowing capacity under Revolving Credit Facility	668		315
Total debt obligations	3,194		3,687

Other Liquidity

On March 2, 2026, NVIDIA made a $2 billion investment in the Company through the purchase of shares of the Company’s Common Stock. The proceeds from the investment will be used to support research and development, future capacity and operations as we build out our manufacturing capabilities. We also entered into a multi-year capacity agreement that may require incremental investments in equipment, labor, and working capital to support future production volumes through 2030. While no material liability was recorded at quarter-end solely as a result of entering into the agreement, the arrangement may result in material future cash requirements and could affect revenue concentration, gross margin, and capital expenditures as volumes ramp. See Note 12. Equity and Redeemable Preferred Stock for further information.

On December 4, 2023, the Company completed two investment agreements under which Silicon Carbide LLC, a Company subsidiary, received $1.0 billion cash in exchange for 25% of the equity of that entity. Such funds have and will continue to be used primarily to fund future capital expansion in our silicon carbide business and will enable us to increase our available free cash flow to provide greater financial and operational flexibility to execute our capital allocation priorities. See Note 13. Noncontrolling Interests included in Item 1 for further information.

The Company believes existing cash, cash flow from operations, and available borrowing capacity from its Senior Credit Facilities will be sufficient to fund its needs for working capital, capital expenditures, repayment of scheduled long-term borrowings and lease obligations, investments in R&D, and internal and external growth objectives at least through the next twelve months.

35

Our cash and cash equivalent balances are generated and held in numerous locations throughout the world, including amounts held outside the United States. As of March 31, 2026, the Company held approximately $808 million of cash, cash equivalents and restricted cash outside of the United States. Generally, cash balances held outside the United States could be repatriated to the United States.

At March 31, 2026, we had $633 million of restricted cash, which includes $630 million at Silicon Carbide LLC that is restricted for use by only that subsidiary.

Item 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risks

We are exposed to market risks arising from adverse changes in foreign currency exchange rates and interest rates. In the normal course of business, we have the option to use a variety of techniques and derivative financial instruments as part of our overall risk management strategy, which is primarily focused on our exposure in relation to the Chinese Renminbi, Euro, Swiss Franc, Japanese Yen, Singapore Dollar and Korean Won. As of September 30, 2024, after weighing the costs and benefits of hedging foreign exchange risks on our global balance sheets, we paused our balance sheet hedging program indefinitely. We continue to analyze these risks and the costs and benefits inherent in a hedging program.

Interest Rate Risks

As of March 31, 2026, our total borrowings include variable rate borrowings, which expose us to changes in interest rates. On February 23, 2022, we entered into an interest rate cap, amended on March 20, 2023, with an effective date of July 1, 2023. On September 1, 2024, we increased the notional amount from $500 million to $1,500 million. If we had not effectively hedged our variable rate debt, a change in the interest rate of 100 basis points on these variable rate borrowings would have resulted in additional interest expense of $6 million and $19 million, respectively, for the three and nine months ended March 31, 2026.

Item 4.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company’s management evaluated, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer and Treasurer, the effectiveness of the Company’s disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this Quarterly Report on Form 10-Q. The Company’s disclosure controls were designed to provide reasonable assurance that information required to be disclosed in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. It should be noted that the design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. However, the controls have been designed to provide reasonable assurance of achieving the controls’ stated goals. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer and Treasurer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report on Form 10-Q.

Changes in Internal Control over Financial Reporting

No changes in the Company’s internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) were implemented during the Company’s most recently completed fiscal quarter that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

36

Part II – Other Information

Item 1.    LEGAL PROCEEDINGS

The Company and its subsidiaries are involved in various claims and lawsuits incidental to its business. The resolution of each of these matters is subject to various uncertainties, and it is possible that these matters may be resolved unfavorably to the Company. Management believes, after consulting with legal counsel, that the ultimate liabilities, if any, resulting from such legal proceedings will not materially affect the Company’s financial condition, liquidity, or results of operations.

Item 1A.    RISK FACTORS

In addition to the other information set forth in this Quarterly Report on Form 10-Q, carefully consider the risk factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended June 30, 2025 and additional risk factors that may be identified from time to time in filings of the Company, any of which could materially affect our business, financial condition or future results. Those risk factors are not the only risks facing the Company. Additional risks and uncertainties not currently known or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Item 5.    OTHER INFORMATION

During the three months ended March 31, 2026, no director or officer (as defined in Rule 16a-1(f) of the Exchange Act) of the Company adopted, modified, or terminated a “Rule 10b5-1 trading agreement” or “non-Rule 10b5-1 trading agreement,” as each term is defined in Item 408 of Regulation S-K of the Exchange Act.

Recently Issued Financial Accounting Standards

In December 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, on either a prospective or retrospective basis. Early adoption is permitted. ASU 2023-09 is effective for the Company’s year beginning July 1, 2025 and the new disclosure requirements will be reflected in the Company’s Annual Report on Form 10-K for the year ending June 30, 2026.

In November 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40), Disaggregation of Income Statement Expenses.” This ASU requires disclosure about specific types of expenses included in expense captions including purchases of inventory, employee compensation, depreciation, amortization, and depletion. This ASU is effective for our annual disclosures starting in fiscal year 2028 and interim periods starting in fiscal year 2029. Early adoption is permitted. A public entity should apply the amendments in this ASU on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

Revenue from Contracts with Customers

Revenue from Contracts with Customers

We disaggregate revenue by market and geography. We believe that disaggregating revenue by market and geography provides the most relevant information regarding the nature, amount, timing, and uncertainty of revenues and cash flows. We do not present other levels of disaggregation, such as by type of products, customer, contracts, duration of contracts, timing of transfer of control and sales channels, as this information is not used by our chief operating decision maker (“CODM”) to manage the business.

Effective July 1, 2025, the Company aligned its reporting of revenues into two markets: (i) Datacenter & Communications, and (ii) Industrial. All prior period market and segment disclosure information has been reclassified to conform to the current reporting structure.

The following tables summarize disaggregated revenue by market ($000):

	Three Months Ended March 31,				Nine Months Ended March 31,
Markets	2026		2025		2026		2025
Datacenter & Communications	$	1,361,677	$	968,650	$	3,659,627	$	2,736,838

Total Revenues	$	1,805,641	$	1,497,879	$	5,072,648	$	4,280,679

Contract Liabilities

Payments received from customers are based on invoices or billing schedules as established in contracts with customers. Contract liabilities generally relate to payments received in advance of performance under the contract. Contract liabilities are recognized as revenue when the performance obligations have been satisfied. During the nine months ended March 31, 2026, we recognized revenue of $52 million related to customer payments that were included as contract liabilities in the Condensed Consolidated Balance Sheet as of June 30, 2025. We had $70 million of contract liabilities recorded in the Condensed Consolidated Balance Sheet as of March 31, 2026. As of March 31, 2026, $59 million of contract liabilities is included within Other accrued liabilities, and $11 million is included within Other liabilities on the Condensed Consolidated Balance Sheet.

Goodwill and Other Intangible Assets

Effective July 1, 2025, the Company realigned its organizational structure into two reporting segments: (i) Datacenter & Communications, and (ii) Industrial. The information in the table below reflects the impact of this segment change whereby goodwill was reallocated to the respective reporting units on the first day of fiscal 2026 using a relative fair value approach. As a result of the change in reportable segments, the Company performed an impairment assessment immediately before and immediately after the segment change became effective, and no impairment of goodwill was identified.

Assets Held-for-Sale and Sale of Business

In the fourth quarter of fiscal 2025, management entered into non-binding agreements to sell several entities. As a result of classifying these entities as held-for-sale, the Company recorded non-cash impairment charges of $85 million within the Industrial segment. These charges were recognized in Impairment of assets held-for-sale in our Condensed Consolidated Statements of Earnings (Loss) in the fourth quarter of fiscal 2025 to reduce the carrying values of the entities to their estimated fair value.

On September 2, 2025, the Company completed the sale of its aerospace and defense business, which was part of the Industrial segment, for approximately $400 million, subject to customary post-closing adjustments. In connection with the sale, the Company recorded a gain of $115 million and incurred approximately $9 million in transaction related costs which were recorded in Gain on sale of business and SG&A expenses, respectively, in the Condensed Consolidated Statements of Earnings (Loss) for the first quarter of fiscal 2026.

In the nine months ended March 31, 2026, the Company recorded additional non-cash impairment charges of $20 million within the Industrial segment related to two entities that were classified as held-for-sale during the first and second quarters of fiscal 2026. The charges were recorded in Impairment of assets held-for-sale in the Condensed Consolidated Statements of Earnings (Loss) for the first and second quarters of fiscal 2026 to reduce the carrying value of entities classified as held-for-sale to their estimated fair value.

On January 30, 2026, the Company completed the sale of its product division based in Munich, Germany that makes tools for materials processing. In connection with the sale, the Company recorded a gain of $9 million which was recorded in Gain on sale of business in the Condensed Consolidated Statements of Earnings (Loss) for the third quarter of fiscal 2026. The total loss associated with the sale was $96 million, substantially all of which was recognized in Impairment of assets held-for-sale in the Condensed Consolidated Statements of Earnings (Loss), including $81 million in the fourth quarter of fiscal 2025, $13 million in the first quarter of fiscal 2026 and $11 million in the second quarter of fiscal 2026.

Current assets and current liabilities held for sale are recorded in Prepaid and other current assets and Other accrued liabilities, respectively, in our Condensed Consolidated Balance Sheets. Noncurrent assets and noncurrent liabilities held for sale are recorded in Other assets and Other liabilities, respectively, in our Condensed Consolidated Balance Sheets. Assets and liabilities held-for-sale are in the Industrial segment. There were no assets or liabilities held for sale as of March 31, 2026.

Senior Credit Facilities

On July 1, 2022 (the “Closing Date”), Coherent entered into a credit agreement (the “Credit Agreement”) by and among the Company, as borrower (in such capacity, the “Borrower”), the lenders, and other parties thereto, and JP Morgan Chase Bank, N.A., as administrative agent and collateral agent, which provided for senior secured financing of $4.0 billion, consisting of a term loan A credit facility (the “Term A Facility”) maturing July 1, 2027, with an aggregate principal amount of $850 million, a term loan B credit facility (the “Term B Facility,” and together with the Term A Facility, the “Term Facilities”) maturing July 1, 2029, with an aggregate principal amount of $2,800 million, and a revolving credit facility (the “Revolving Credit Facility,” and together with the Term Facilities, the “Senior Credit Facilities”) maturing July 1, 2027, in an aggregate available amount of $350 million, including a letter of credit sub-facility of up to $50 million. On the Closing Date, the Borrower and certain of its direct and indirect subsidiaries provided a guaranty of all obligations of the Borrower and the other loan parties under the Credit Agreement and the other loan documents, secured cash management agreements and secured hedge agreements with the lenders and/or their affiliates (subject to certain exceptions). The Borrower and the other guarantors have also granted a security interest in substantially all of their assets to secure such obligations. On March 31, 2023, Coherent entered into Amendment No. 1 to the Credit Agreement, which replaced the adjusted LIBOR-based rate of interest therein with an adjusted SOFR-based rate of interest. On April 2, 2024, Coherent entered into Amendment No. 2 to the Credit Agreement, under which the principal amount of term B loans outstanding under the Credit Agreement (the “Existing Term B Loans”) were replaced with an equal amount of new term loans (the “New Term B Loans”) having substantially similar terms as the Existing Term B Loans, except with respect to the interest rate applicable to the New Term B Loans and certain other provisions. On January 2, 2025, Coherent entered into Amendment No. 3 to the Credit Agreement, under which the principal amount of New Term B Loans outstanding under the Credit Agreement were replaced with an equal amount of new term loans (the “New Term B-2 Loans”) having substantially similar terms as the New Term B Loans, except with respect to the interest rate applicable to the New Term B-2 Loans and certain other provisions. The maturity of the New Term B-2 Loans and Revolving Credit Facility was unchanged.

On September 26, 2025, the Company entered into Amendment No. 4 (“Amendment No. 4”) and Amendment No. 5 (“Amendment No. 5”) to the Credit Agreement. Under Amendment No. 4, (i) the existing revolving credit commitments were refinanced and replaced with new senior secured revolving credit commitments, (ii) $350 million of senior secured incremental revolving credit commitments were added, increasing the total revolving credit facility to $700 million (the “2025 Revolving Loans”), including a letter of credit sub-facility of up to $100 million, and (iii) a $1,250 million new tranche of senior secured incremental term A loans was added (the “2025 Incremental Term A Loans”), the proceeds of which were used, in part, to repay all outstanding principal, interest and fees of term A loans outstanding under the Credit Agreement (the “Existing Term A Loans”). As amended, the 2025 Revolving Loans and the 2025 Incremental Term A Loans each bear interest at an adjusted SOFR rate subject to a 0.00% floor plus a range of 1.25% to 2.25% based on the Company’s total net leverage ratio. The interest rate applicable to the 2025 Revolving Loans and the 2025 Incremental Term A Loans is initially a SOFR-based rate plus 1.50% as of March 31, 2026. The 2025 Revolving Loans and the 2025 Incremental Term A Loans mature on the earlier of September 26, 2030 or a “Springing Maturity Date,” which is a date that is 91 days prior to the stated maturity of either (i) the Company’s unsecured senior notes or (ii) the term B loans then outstanding if, on such 91st day, the applicable senior notes or term B loans remain outstanding and liquidity is less than (x) $250 million plus (y) the aggregate outstanding principal amount of such notes or term B loans, as applicable. Under Amendment No. 5, the outstanding New Term B-2 Loans were replaced with an equal amount of new term loans (the “New Term B-3 Loans”) having substantially similar terms as the New Term B-2 Loans, except with respect to the interest rate applicable to the New Term B-3 Loans and certain other provisions. As further amended, the New Term B-3 Loans bear interest at a SOFR-based rate (subject to a 0.50% floor) plus 1.75% as of March 31, 2026. The New Term B-3 Loans will mature on July 1, 2029.

Debt extinguishment costs related to the termination of the Existing Term Loans of $3 million were expensed in Other expense (income), net in the Condensed Consolidated Statement of Earnings during the nine months ended March 31, 2026.

In relation to the Term Facilities, the Company incurred interest expense, including amortization of debt issuance costs and the benefit of the interest rate cap and swap, of $32 million and $111 million in the three and nine months ended March 31, 2026, respectively, and $44 million and $150 million in the three and nine months ended March 31, 2025, respectively, which is included in Interest expense in the Condensed Consolidated Statements of Earnings (Loss).

On July 1, 2023, our interest rate cap became effective, which, together with our interest rate swap (through September 30, 2024), reduced interest expense by $3 million and $14 million during the three and nine months ended March 31, 2026, respectively, and $6 million and $27 million in the three and nine months ended March 31, 2025, respectively. The amortization of debt issuance costs included in interest expense was $3 million and $14 million in the three and nine months ended March 31, 2026, respectively, and $5 million and $14 million in the three and nine months ended March 31, 2025, respectively. Debt issuance costs are presented as a reduction of long-term debt in the Condensed Consolidated Balance Sheets.

As of March 31, 2026, the Company was in compliance with all covenants under the Senior Credit Facilities.

The Company had aggregate availability of $668 million under its Revolving Credit Facility as of March 31, 2026.

Debt Assumed through Acquisition

We assumed the remaining balances of three term loans with the closing of the acquisition of Coherent, Inc., two of which were repaid prior to June 30, 2024. The aggregate principal amount outstanding under the remaining assumed term loan is $15 million as of March 31, 2026 and is for a Facility Construction Loan in Germany due in 2030 that bears interest at 1.55% per annum. Payments are made quarterly.

5.000% Senior Notes due 2029

On December 10, 2021, the Company issued $990 million aggregate principal amount of Senior Notes pursuant to the indenture, dated as of December 10, 2021 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee. The Senior Notes are guaranteed by each of the Company’s domestic subsidiaries that guarantee its obligations under the Senior Credit Facilities. Interest on the Senior Notes is payable on December 15 and June 15 of each year, commencing on June 15, 2022, at a rate of 5.000% per annum. The Senior Notes will mature on December 15, 2029.

Beginning December 15, 2024, the Company may redeem the Senior Notes, in whole at any time or in part from time to time, at the redemption prices set forth in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. In addition, at any time prior to December 15, 2024, the Company had the ability to (but did not) redeem the Senior Notes, at its option, in whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount of the Senior Notes redeemed, plus a “make-whole” premium set forth in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. Notwithstanding the foregoing, prior to December 15, 2024, the Company had the ability to redeem up to 40% of the aggregate principal amount of the Senior Notes using the proceeds of certain equity offerings as set forth in the Indenture, at a redemption price equal to 105.000% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date.

Leases

We determine if an arrangement is a lease at inception for arrangements with an initial term of more than 12 months, and classify it as either finance or operating.

Finance leases are generally those that allow us to substantially utilize or pay for the entire asset over its estimated useful life. Finance lease assets are recorded in Property, plant and equipment, net, and finance lease liabilities within Other accrued liabilities and Other liabilities on our Condensed Consolidated Balance Sheets. Finance lease assets are amortized in operating expenses on a straight-line basis over the shorter of the estimated useful lives of the assets or the lease term, with the interest component for lease liabilities included in interest expense and recognized using the effective interest method over the lease term.

Operating leases are leases that do not qualify as finance leases and are recorded in Other assets and Operating lease current liabilities and Operating lease liabilities on our Condensed Consolidated Balance Sheets. Operating lease assets are amortized on a straight-line basis in operating expenses over the lease term.

Our lease liabilities are recognized based on the present value of the remaining fixed lease payments, over the lease term, using a discount rate of similarly secured borrowings available to the Company. For the purpose of lease liability measurement, we consider only payments that are fixed and determinable at the time of commencement. Any variable payments that depend on an index or rate are expensed as incurred. We account for non-lease components, such as common area maintenance, as a component of the lease, and include it in the initial measurement of our leased assets and corresponding liabilities. Our lease terms and conditions may include options to extend or terminate. An option is recognized when it is reasonably certain that we will exercise that option.

Our lease assets also include any lease payments made, and exclude any lease incentives received prior to commencement. Our lease assets are tested for impairment in the same manner as long-lived assets used in operations.

The following table presents lease costs, which include leases for arrangements with an initial term of more than 12 months, remaining lease terms, and discount rates ($000):

Restructuring Plans

2023 Restructuring Plan

On May 23, 2023, the Board of Directors approved the 2023 Plan which includes site consolidations, facilities moves and closures, as well as the relocation and requalification of certain manufacturing facilities. These restructuring actions were intended to realign our cost structure as part of a transformation to a simpler, more streamlined, resilient and sustainable business model. We evaluate restructuring charges in accordance with ASC 420, Exit or Disposal Cost Obligations (“ASC 420”), and ASC 712, Compensation-Nonretirement Post-Employment Benefits (“ASC 712”).

In the three months ended March 31, 2026, these activities resulted in $4 million of net charges primarily for site closure and move costs and employee termination costs. In the nine months ended March 31, 2026, these activities resulted in $2 million of net recoveries primarily for adjustments to employee termination costs previously accrued partially offset by site move costs. In the three months ended March 31, 2025, these activities resulted in $11 million of net charges primarily for employee termination costs and site move costs. In the nine months ended March 31, 2025, these activities resulted in $43 million of net

charges primarily for impairment losses associated with the sale of our Newton Aycliffe business, employee termination costs, site move costs and accelerated depreciation.

Activity and accrual balances for the 2023 Plan were as follows for the first three quarters of fiscal 2026 and 2025 ($000):

At March 31, 2026, $7 million and $22 million of accrued severance related costs were included in other accrued liabilities and other liabilities on our Condensed Consolidated Balance Sheet, respectively, and are expected to result in cash expenditures through fiscal 2028. The current and prior year severance related net charges are primarily comprised of accruals and adjustments for severance and pay for employees being terminated due to the consolidation of certain manufacturing sites, with severance recorded in accordance with ASC 712.

For the three and nine months ended March 31, 2026 and March 31, 2025, restructuring costs were primarily incurred in the Datacenter & Communications segment. Restructuring charges (recoveries) are recorded in Restructuring charges in our Condensed Consolidated Statements of Earnings (Loss).

2025 Restructuring Plan

Commencing in the quarter ended March 31, 2025, and as part of the ongoing strategic review of the Company’s business, the Company’s management approved the 2025 Plan. In connection therewith, the Company incurs charges for related severance

and benefits, lease and contract termination costs, asset write-offs, facilities move and other restructuring costs. We evaluate restructuring charges in accordance with ASC 420 and ASC 712.

In the three and nine months ended March 31, 2026, these activities resulted in $31 million and $59 million, respectively, of net charges primarily related to write-off of property and equipment, employee termination and site closure costs. In the three months ended March 31, 2025, these activities resulted in $63 million of net charges primarily for the write-off of property and equipment and employee termination costs. We expect the restructuring actions to be substantially completed by the end of fiscal 2026. However, the actual timing and costs associated with these restructuring actions may differ from our current expectations and estimates and such differences may be material.

Activity and accrual balances for the 2025 Plan were as follows for the first three quarters of fiscal 2026 and 2025 ($000):

	Severance		Asset Write-Offs		Other		Total Accrual

At March 31, 2026, $26 million of accrued severance related costs were included in other accrued liabilities and are expected to result in cash expenditures primarily through fiscal 2026. The current year severance related net charges are primarily comprised of accruals for severance and pay for employees being terminated due to the consolidation of certain manufacturing and distribution sites as well as workforce reductions, with severance recorded in accordance with ASC 712. At March 31, 2026, total liabilities for asset write-offs and other contract costs of $10 million and $12 million were included in other accrued liabilities and other liabilities, respectively, on our Condensed Consolidated Balance Sheet.

The restructuring costs were incurred primarily in the Industrial segment for the three months ended March 31, 2026. For the nine months ended March 31, 2026, restructuring charges were incurred primarily in the Industrial and Corporate segments. For the three months ended March 31, 2025, restructuring charges were primarily incurred in the Industrial and Datacenter & Communications segments.

Regulatory Matters

In January 2025, the Company received an inquiry from the Bureau of Industry and Security (“BIS”) concerning past product sales to Huawei; the Company is cooperating with BIS’s inquiry and conducting an internal review of those sales to determine what products are subject to Export Administrative Regulations (“EAR”) and consequently restricted for export, reexport, and transfer when Huawei is a party to the transaction. The Company has stopped shipping products to Huawei. The Company is

currently in discussions with BIS regarding past product sales and cannot predict the outcome of those discussions. While the Company has received requests for additional information in this matter, the Company has not yet received any determination from BIS. In the event that the Company is found to have violated the EAR, the Company may be required to incur significant penalties and/or costs or expense as a result of the inquiry and to comply with, or remedy any violations of these regulations, but at this time, the Company is unable to determine an estimate or range of loss.

Equity and Redeemable Preferred Stock

Common shares issued

On March 2, 2026, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with NVIDIA Corporation (“NVIDIA”), pursuant to which the Company issued and sold 7,788,161 shares of Common Stock at a price of $256.80 per share, for aggregate gross proceeds of $2 billion. The transaction was completed as a private placement in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended. NVIDIA’s investment will support research and development initiatives, future capacity expansion, and operational capabilities, as Coherent expands its manufacturing footprint.

The shares issued to NVIDIA are subject to a contractual lock-up for a period of six months following the closing date, during which NVIDIA may not, without the Company’s prior written consent, directly or indirectly transfer or otherwise dispose of the shares or enter into transactions that transfer the economic risks or benefits of ownership.

The Purchase Agreement includes a price protection provision that is effective for a period of six months following execution of the Purchase Agreement. The Company evaluated the price protection provision under applicable U.S. GAAP, including ASC 815, Derivatives and Hedging, and ASC 480, Distinguishing Liabilities from Equity, and determined that the provision is indexed to the Company’s own stock and meets the criteria for equity classification. Accordingly, the price protection provision is not accounted for as a derivative liability and no separate fair value measurement is required subsequent to issuance. Any potential issuance of additional shares or cash settlement pursuant to the price protection provision, if triggered, will be accounted for as an adjustment to equity.

Preferred stock

As of March 31, 2026, the Company’s amended and restated articles of incorporation authorize the Board of Directors, without shareholder approvals, to issue up to 5 million shares of preferred stock. As of that date, 2.3 million shares of mandatory convertible preferred shares had been previously issued and subsequently converted into shares of the Company’s Common Stock. During the quarter ended December 31, 2025, 75,000 shares and 140,000 shares of previously issued Series B-1 (“Series B-1 Preferred Stock”) and B-2 convertible preferred stock (“Series B-2 Preferred Stock” and, together with the Series B-1 Preferred Stock, the “Series B Preferred Stock”), no par value per share, respectively, were converted into an aggregate of 30.1 million shares of Common Stock. The majority of the Series B-1 and B-2 convertible preferred stock was converted by the holder and the remainder was converted by the Company. No Series B convertible preferred stock was outstanding at March 31, 2026. As a result of the conversion, $2.5 billion was reclassified from Mezzanine Equity to Common Stock during the quarter ended December 31, 2025.

Series B Convertible Preferred Stock - Prior to Conversion in the quarter ended December 31, 2025

In March 2021, the Company issued 75,000 shares of Series B-1 Preferred Stock for $10,000 per share, resulting in an aggregate purchase price of $750 million. On July 1, 2022, the Company issued 140,000 shares of Series B-2 Preferred Stock for $10,000 per share and an aggregate purchase price of $1.4 billion.

The shares of Series B Preferred Stock were convertible into shares of Coherent Common Stock as follows:

•at the election of the holder, each share of Series B Preferred Stock could have been converted into shares of Coherent Common Stock at a conversion price of $85 per share (as it may be adjusted from time to time, the “Conversion Price”); and

•at the election of the Company at the then-applicable Conversion Price if the volume-weighted average price of Coherent Common Stock exceeded 150% of the then-applicable Conversion Price for 20 trading days out of any 30 consecutive trading days.

The issued shares of Series B Preferred Stock had voting rights, voting as one class with the Coherent Common Stock, on an as-converted basis, subject to limited exceptions.

The Series B Preferred Stock was initially measured at fair value less issuance costs, accreted to its redemption value over a 10-year period (using the effective interest method) with such accretion accounted for as deemed dividends and reductions to Net Earnings (Loss) Available to Common Shareholders.

Preferred stock dividends are presented as a reduction to Retained earnings on the Condensed Consolidated Balance Sheets. The Company entered into an agreement with the holder of the Series B Preferred Stock to waive dividends effective November 20, 2025. Due to the conversion of the Series B Preferred Stock to Common Stock in the quarter ended December 31, 2025, no dividends were declared or paid for the quarters ended December 31, 2025 or March 31, 2026.

The following table presents dividends per share and dividends recognized:

Income Taxes

Income Taxes

The Company’s fiscal year-to-date effective income tax rate was 3% at March 31, 2026 compared to 19% for the same period in the prior fiscal year. The variance from the U.S. statutory federal income tax rate of 21% was primarily driven by differences between U.S. and foreign tax rates, as well as discrete tax benefits related to changes in German tax law, releases of uncertain tax positions, and excess tax benefits associated with stock-based compensation.

U.S. GAAP prescribes the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements which includes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As of March 31, 2026 and June 30, 2025, the Company’s gross unrecognized tax benefit, excluding interest and penalties, was $68 million and $124 million, respectively. The Company has classified the uncertain tax positions as non-current income tax liabilities, as the amounts are not expected to be paid within one year. Due to the U.S. valuation allowance, a large portion of the gross unrecognized tax benefit will not impact the tax rate if recognized. As of March 31, 2026, $6 million of the gross unrecognized tax benefit would impact the effective tax rate if recognized. The Company recognizes interest and penalties related to uncertain tax positions in the income tax provision in the Condensed Consolidated Statements of Earnings (Loss).

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per common share is computed by dividing net earnings available to the common shareholders by the weighted-average number of shares of common stock outstanding during the period.

Diluted earnings per common share is computed by dividing the diluted earnings available to the common shareholders by the weighted-average number of shares of common stock and potentially dilutive shares of common stock outstanding during the period. Potentially dilutive shares whose effect would have been anti-dilutive are excluded from the computation of diluted earnings per common share.

The dilutive effect of equity awards is calculated based on the average stock price for each fiscal period, using the treasury stock method. For the three and nine months ended March 31, 2026 and the nine months ended March 31, 2025, diluted shares outstanding include the dilutive effect of the potential shares of Coherent Common Stock issuable from performance and restricted shares. For the three months ended March 31, 2025, as the Company was in a net loss position, there were no dilutive shares.

For the nine months ended March 31, 2026, diluted earnings per share included the potentially dilutive effect of the shares of Coherent Common Stock issuable upon conversion of the Series B Convertible Preferred Stock, calculated using the If-Converted method through their respective conversion dates, as the effect was dilutive. For the three months ended March 31, 2025, diluted loss per share excluded the shares of Coherent Common Stock issuable upon conversion of the Series B Convertible Preferred Stock under the If-Converted method, as the effect was anti-dilutive. For the nine months ended March 31, 2025, diluted earnings per share likewise excluded the potentially dilutive effect of such shares, as the effect was anti-dilutive.

The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations (000, except per share data):

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

The Company’s businesses are organized and managed into segments based on similarities in products and services. Segment determination reflects how the CODM evaluates the Company’s operations for decision-making operating decisions and performance assessment. Effective July 1, 2025, the Company realigned its organizational structure and now identifies multiple operating segments, which are aggregated into two reportable segments: (i) Datacenter & Communications, and (ii) Industrial. In accordance with ASC 280, Segment Reporting, the aggregation of the Company’s segments is based on similarities in economic characteristics, product and service types, production processes, type or class of customers, and distribution methods. Previously, financial results had been reported in the following three segments: (i) Networking, (ii) Materials, and (iii) Lasers. Comparative prior period segment information has been recast to conform to the new segments.

The Datacenter & Communications segment has locations in the United States, Australia, China, Germany, Malaysia, South Korea, Sweden, Switzerland, Thailand, the Philippines and Vietnam. This segment sells primarily into the datacenter and communications market, including transceivers, systems, subsystems, modules, components, optics, and semiconductor devices.

The Industrial segment has locations in the United States, China, Finland, Germany, Italy, Japan, Malaysia, Singapore, South Korea, Spain, Sweden, Taiwan, the Philippines, the United Kingdom and Vietnam. This segment sells primarily into the industrial market, which includes lasers, systems, optics, components and materials for semiconductor and display capital equipment, precision manufacturing, life sciences, consumer electronics, scientific research and automotive and market applications.

Our CODM receives and reviews financial information based on the operating segments that are aggregated into the two reportable segments. Our CODM evaluates each segment’s performance and allocates resources based on segment revenue and segment profit, as our CODM believes segment profit is a more comprehensive profitability measure for each operating segment. Our CODM is regularly provided with segment revenue and segment profit information to assess performance of each segment. Segment profit includes operating expenses directly managed by operating segments, including research and development, direct sales, marketing and administrative expenses. Segment profit does not include share-based compensation, acquisition or integration related costs, amortization and impairment of acquisition-related intangible assets, restructuring charges, impairment charges on assets held-for-sale, gain on sale of businesses and certain other charges or gains. Additionally, we do not allocate Corporate strategic research and development, strategic marketing and sales expenses and shared general and administrative expenses, as these expenses are not directly attributable to our operating segments. The segments are managed separately due to the unique products and markets that each serves. The Company derives its reportable segment results based on how financial information is reported and aggregated within its management reporting system. The CODM uses segment profit as a key metric in the forecasting process and in making decisions related to capital allocation and resource deployment across segments. The accounting policies are consistent across each segment. Assets by segment are not a measure used to assess the performance of the company by the CODM and thus are not reported in our disclosures.

The following table summarizes selected financial information of our operations by segment and reconciles segment profit to consolidated earnings (loss) before income taxes for the periods presented ($000):

Fair Value of Financial Instruments

9 Months Ended

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The FASB defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous markets for the asset and liability in an orderly transaction between market participants at the measurement date. We estimate fair value of our financial instruments utilizing an established three-level hierarchy in accordance with U.S. GAAP. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date as follows:

•Level 1 – Valuation is based upon unadjusted quoted prices for identical assets or liabilities in active markets.

•Level 2 – Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instruments.

•Level 3 – Valuation is based upon other unobservable inputs that are significant to the fair value measurements.

The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement.

On February 23, 2022, we entered into an interest rate cap (the “Cap”) with an effective date of July 1, 2023. On March 20, 2023, we amended the Cap to replace the current reference rate (LIBOR) with SOFR, to be consistent with Amendment No. 1 to the Credit Agreement. See Note 8. Debt for further information. The Cap manages our exposure to interest rate movements on a portion of our floating rate debt. The Cap provides us with the right to receive payment if one-month SOFR exceeds 1.92%. Beginning in July 2023, we began to pay a fixed monthly premium based on an annual rate of 0.853% for the Cap. On September 1, 2024, we increased the notional amount from $500 million to $1,500 million. The fair value of the interest rate cap of $6 million and $17 million is recognized in the Condensed Consolidated Balance Sheet within Prepaid and other current assets and Other assets as of March 31, 2026 and June 30, 2025, respectively.

The Cap, as amended, is designed to mirror the terms of the Credit Agreement as amended on March 31, 2023. We designated the Cap as a cash flow hedge of the variability of the SOFR based interest payments on the Term Facilities. Every period over the life of the hedging relationship, the entire change in fair value related to the hedging instrument will first be recorded within AOCI. Amounts accumulated in AOCI are reclassified into interest expense in the same period or periods in which interest expense is recognized on the Credit Agreement, or its direct replacement. The fair value of the Cap is determined using widely accepted valuation techniques and reflects the contractual terms of the Cap including the period to maturity, and while there are no quoted prices in active markets, it uses observable market-based inputs, including interest rate curves. The fair value analysis also considers a credit valuation adjustment to reflect nonperformance risk of both the Company and the single counterparty. The Cap is classified as a Level 2 item within the fair value hierarchy.

We estimated the fair value of the Senior Notes and the Term Facilities (“Debt Facilities”) based on quoted market prices as of the last trading day prior to March 31, 2026; however, the Debt Facilities have only a limited trading volume and as such this fair value estimate is not necessarily the value at which the Debt Facilities could be retired or transferred. We concluded that this fair value measurement should be categorized within Level 2. The carrying values of the Debt Facilities are net of unamortized discount and issuance costs. See Note 8. Debt for details on the Company’s Debt Facilities.

The fair value and carrying value of the Debt Facilities were as follows ($000):

	March 31, 2026				June 30, 2025
	Fair Value		Carrying Value		Fair Value		Carrying Value
Senior Notes	$	972,824	$	985,797	$	973,190	$	985,034
Term A Facility	1,144,902		1,134,543		632,960		616,234
Term B Facility	1,083,380		1,057,180		2,108,938		2,065,880

Our borrowings, including our lease obligations and the Debt Facilities, are considered Level 2 among the fair value hierarchy.

Cash and cash equivalents are considered Level 1 among the fair value hierarchy and approximate fair value because of the short-term maturity of those investments. At March 31, 2026, time deposits of $825 million, with maturities of one year or less, are recorded in Short-term investments on the Condensed Consolidated Balance Sheet are considered Level 1 among the fair value hierarchy and approximate fair value because of the short-term maturity of those investments.

At March 31, 2026, total restricted cash was $633 million, which includes $630 million held by Silicon Carbide LLC and restricted for use only by that subsidiary, and $3 million of cash restricted for other purposes in other entities. At June 30, 2025, total restricted cash was $724 million, which includes $720 million of cash held by Silicon Carbide LLC and restricted for use only by that subsidiary, and $4 million of cash restricted for other purposes in other entities. The restricted cash is invested in money market accounts and time deposits, with maturities of one year or less, that are held-to-maturity, are considered Level 1 among the fair value hierarchy and approximate fair value. Restricted cash that is expected to be spent and released from restriction after 12 months is classified as non-current on the Condensed Consolidated Balance Sheets.

We, from time to time, purchase foreign currency forward exchange contracts that permit us to sell specified amounts of these foreign currencies for pre-established U.S. dollar amounts at specified dates that represent assets or liabilities on the balance sheets of certain subsidiaries. These contracts are entered into for the purpose of limiting translational exposure to changes in currency exchange rates and which otherwise would expose our earnings, on the revaluation of our aggregate net assets or liabilities in respective currencies, to foreign currency risk. At March 31, 2026, we had no foreign currency forward contracts. The fair values of these instruments, when outstanding, are measured using valuations based upon quoted prices for similar assets and liabilities in active markets (Level 2) and are valued by reference to similar financial instruments, adjusted for credit risk and restrictions and other terms specific to the contracts. Realized gains related to these contracts for the three and nine months ended March 31, 2026 were zero and realized gains related to these contracts for the three and nine months ended March 31, 2025 were zero and $16 million, respectively, and were included in Other income, net in the Condensed Consolidated Statements of Earnings (Loss).

Basis of Presentation

The condensed consolidated financial statements of Coherent Corp. (“Coherent”, the “Company”, “we”, “us” or “our”) for the three and nine months ended March 31, 2026 and 2025 are unaudited. In the opinion of management, all adjustments considered necessary for a fair presentation for the periods presented have been included. All adjustments are of a normal recurring nature unless disclosed otherwise. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2025 filed with the Securities and Exchange Commission (the “SEC”) on August 15, 2025 and in Exhibit 99.1 to our Current Report on Form 8-K dated December 16, 2025 in which we retrospectively recast historical segment reporting to reflect our current organizational structure. The condensed consolidated results of operations for the three and nine months ended March 31, 2026 are not necessarily indicative of the results to be expected for the full fiscal year. The Condensed Consolidated Balance Sheet information as of June 30, 2025 was derived from the Company’s audited consolidated financial statements.

Reclassification

Certain prior year amounts have been reclassified for consistency with the current year presentation.

Recently Issued Financial Accounting Standards

In December 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, on either a prospective or retrospective basis. Early adoption is permitted. ASU 2023-09 is effective for the Company’s year beginning July 1, 2025 and the new disclosure requirements will be reflected in the Company’s Annual Report on Form 10-K for the year ending June 30, 2026.

In November 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40), Disaggregation of Income Statement Expenses.” This ASU requires disclosure about specific types of expenses included in expense captions including purchases of inventory, employee compensation, depreciation, amortization, and depletion. This ASU is effective for our annual disclosures starting in fiscal year 2028 and interim periods starting in fiscal year 2029. Early adoption is permitted. A public entity should apply the amendments in this ASU on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.
