Note 1 — Basis of Presentation

The accompanying unaudited Consolidated Financial Statements of Veeco have been prepared in accordance with U.S. GAAP as defined in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 270 for interim financial information and with the instructions to Rule 10-01 of Securities and Exchange Commission Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements as the interim information is an update of the information that was presented in Veeco’s most recent annual financial statements. For further information, refer to Veeco’s Consolidated Financial Statements and Notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2024 (“2024 Form 10-K”). In the opinion of management, all adjustments considered necessary for a fair presentation have been included. All such adjustments are of a normal, recurring nature.

Veeco reports interim quarters on a 13-week basis ending on the last Sunday of each quarter. The fourth quarter always ends on the last day of the calendar year, December 31. The 2025 interim quarters end on March 30, June 29, and September 28, and the 2024 interim quarters end on March 31, June 30, and September 29. These interim quarters are reported as March 31, June 30, and September 30 in Veeco’s interim consolidated financial statements.

The preparation of financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Although these estimates are based on management’s knowledge of current events and actions it may undertake in the future, actual results may differ from these estimates.

Accounting Standards Recently Adopted

In December 2023, the FASB issued ASU 2023-09:Improvements to Income Tax Disclosures (Topic 740). This amendment requires public entities annually to disclose consistent categories and greater disaggregation of information in the rate reconciliation and for income taxes paid. It also includes certain other amendments to improve the effectiveness of annual income tax disclosures. This authoritative guidance is effective for the Company’s annual reporting periods beginning January 1, 2025. The amendments require increased annual disclosures on current and comparable reporting periods presented in annual company filings. The resulting new annual disclosure requirements will be reflected in the Company’s 2025 report on Form 10-K.

In November 2024, the FASB issued ASU 2024-04,Debt – Debt with Conversion and Other Options (Subtopic 470-20) which clarifies the conditions in which induced conversion accounting applies to convertible debt by outlining three criteria that must be met for an entity to apply the induced conversion model. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2025 (and interim reporting periods within those annual reporting periods), with early adoption permitted. The Company has decided to adopt ASU 2024-04 on a prospective basis effective during the three and six months ended June 30, 2025, and has applied the amendments in this ASU to the repurchase of the 2027 Notes. Refer to Note 4Liabilities for further details.

Recent Accounting Standards Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statements Expenses (Subtopic 220-40),” to improve income statement expenses disclosure. The standard requires more detailed information related to the types of expenses, including (among other items) the amounts of purchases of inventory, employee compensation, depreciation and intangible asset amortization included within each interim and annual income statement’s expense caption, as applicable. This authoritative guidance can be applied prospectively or retrospectively and will be effective for financial statements issued for annual periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently in the process of evaluating the impact of adoption on its consolidated financial statements.

Pending Merger with Axcelis Technologies, Inc.

On September 30, 2025, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Axcelis Technologies, Inc., a Delaware corporation (“Axcelis”), and Victory Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Axcelis (“Merger Sub”). Pursuant to the Merger Agreement, and subject to the satisfaction or waiver of the conditions specified therein, Merger Sub will merge with and into Veeco (the “Merger”), with Veeco surviving as a wholly-owned subsidiary of Axcelis. See Note 10Subsequent Events for additional information.

Note 2 — Income Per Common Share

Basic income per share is calculated by dividing net income by the weighted average number of shares outstanding during the period. Diluted income per share is calculated by dividing net income available to common shareholders by the weighted average number of shares used to calculate basic income per share plus the weighted average number of common share equivalents outstanding during the period. The dilutive effect of outstanding options to purchase common stock and share-based awards is considered in diluted income per share by application of the treasury stock method. The dilutive effect of performance share units is included in diluted income per common share if the performance targets have been achieved, or would have been achieved if the reporting date was the end of the contingency period. Finally, the Company includes the dilutive effect of shares issuable upon conversion of its Notes in the calculation of diluted income per share using the if-converted method. The Company must settle the principal amount of the 2029 Notes in cash, and has the option to settle any excess of the conversion value over the principal amount in any combination of cash or shares. As such, the Company only includes the excess shares that may be issuable above the principal amount of the 2029 Notes in the dilutive share count, if the effect would be dilutive.

The computations of basic and diluted income per share for the three and nine months ended September 30, 2025 and 2024 are as follows:

Note 3 — Assets

Investments

Short-term investments are generally classified as available-for-sale and reported at fair value, with unrealized gains and losses, net of tax, presented as a separate component of stockholders’ equity under the caption “Accumulated other comprehensive income” in the Consolidated Balance Sheets. These securities may include U.S. treasuries, government agency securities, corporate debt, and commercial paper, all with maturities of greater than three months when purchased. All realized gains and losses and unrealized losses resulting from declines in fair value that are other than temporary are included in “Other operating expense (income), net” in the Consolidated Statements of Operations.

Fair value is the price that would be received for an asset or the amount paid to transfer a liability in an orderly transaction between market participants. Veeco classifies certain assets based on the following fair value hierarchy:

Level 1: Quoted prices in active markets that are unadjusted and accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices for identical assets and liabilities in markets that are not active, quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly; and

Level 3: Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Veeco has evaluated the estimated fair value of financial instruments using available market information and valuations as provided by third-party sources. The use of different market assumptions or estimation methodologies could have a significant effect on the estimated fair value amounts.

The following table presents the portion of Veeco’s assets that were measured at fair value on a recurring basis at September 30, 2025 and December 31, 2024:

There wereno transfers between fair value measurement levels during the three and nine months ended September 30, 2025.

At September 30, 2025 and December 31, 2024, the amortized cost and fair value of available-for-sale securities consist of:

Available-for-sale securities in a loss position at September 30, 2025 and December 31, 2024 consist of:

The contractual maturities of securities classified as available-for-sale at September 30, 2025 were as follows:

Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. There wereno realized gains or losses, or unrealized losses from declines in fair value that are other than temporary, for the nine months ended September 30, 2025 and 2024.

Accounts Receivable

Accounts receivable is presented net of an allowance for doubtful accounts of $1.0 million at September 30, 2025 and December 31, 2024. The Company considers its current expectations of future economic conditions when estimating its allowance for doubtful accounts.

Inventories

Inventories at September 30, 2025 and December 31, 2024 consist of the following:

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets primarily consist of supplier deposits, prepaid value-added tax, lease deposits, prepaid insurance, prepaid software and maintenance, and other receivables. The Company had deposits with its suppliers of $12.9 million and $18.7 million at September 30, 2025 and December 31, 2024, respectively.

Property, Plant, and Equipment

Property, plant, and equipment at September 30, 2025 and December 31, 2024 consist of the following:

For the three and nine months ended September 30, 2025, depreciation expense was $4.1 million and $12.6 million, respectively and $4.5 million and $13.8 million, respectively, for the comparable 2024 period.

Goodwill

Goodwill represents the future economic benefits arising from assets acquired in a business combination that are not individually identified and separately recognized. There wereno changes to goodwill during the nine months ended September 30, 2025.

Intangible Assets

Intangible assets consist of purchased technology, customer relationships, patents, trademarks and tradenames, licenses, and backlog, and are initially recorded at fair value. Long-lived intangible assets are amortized over their estimated useful lives in a method reflecting the pattern in which the economic benefits are consumed or amortized on a straight-line basis if such pattern cannot be reliably determined.

The components of purchased intangible assets were as follows:

Other intangible assets primarily consist of patents, licenses, and backlog.

Note 4 — Liabilities

Accrued Expenses and Other Current Liabilities

The components of accrued expenses and other current liabilities at September 30, 2025 and December 31, 2024 consist of:

Warranty

Warranties are typically valid forone year from the date of system final acceptance. The Company estimates the costs that may be incurred under the warranty which are determined by analyzing specific product and historical configuration statistics and regional warranty support costs and are affected by product failure rates, material usage, and labor costs incurred in correcting product failures during the warranty period. Unforeseen component failures or exceptional component performance can also result in changes to warranty costs. Changes in product warranty reserves for the nine months ended September 30, 2025 include:

Contract Liabilities and Performance Obligations

Contract liabilities consist of unsatisfied performance obligations related to advanced payments received and billing in excess of revenue recognized. The contract liability balance as of December 31, 2024 was approximately $65.0 million, of which the Company recognized approximately $48.0 million in revenue during the nine months ended September 30, 2025.

This reduction in contract liabilities was offset in part by new billings for products and services which were unsatisfied performance obligations to customers and revenue had not yet been recognized as of September 30, 2025.

As of September 30, 2025, the Company has approximately $46.5 million of remaining performance obligations on contracts with an original estimated duration ofone year or more, of which approximately 60% is expected to be recognized withinone year, with the remaining amounts expected to be recognized betweenone tothree years. The Company has elected to exclude disclosures regarding remaining performance obligations that have an original expected duration ofone year or less.

Convertible Senior Notes

2025 Notes

On November 17, 2020, as part of the privately negotiated exchange agreement, the Company issued $132.5 million of 3.50% convertible senior notes due 2025 (the “2025 Notes”). The 2025 Notes bear interest at a rate of 3.50% per year, payable semiannually in arrears on January 15 and July 15 of each year, commencing on July 15, 2021. On May 19, 2023, in connection with the completion of a private offering of $230.0 million aggregate principal amount of 2.875% convertible senior notes due 2029 described below, the Company repurchased and retired approximately $106.0 million in aggregate principal amount of its outstanding 2025 Notes. The remaining principal amount of $26.5 million 2025 Notes matured on January 15, 2025 and were settled through the issuance of 1.1 million shares of the Company’s common stock to the noteholders.

2027 Notes

On May 18, 2020, the Company completed a private offering of $125.0 million of 3.75% convertible senior notes due 2027 (the “2027 Notes”). The Company received net proceeds of approximately $121.9 million, after deducting underwriting discounts and fees and expenses payable by the Company. Additionally, the Company used approximately $10.3 million of cash to purchase capped calls, discussed below. The 2027 Notes bore interest at a rate of 3.75% per year, payable semiannually in arrears on June 1 and December 1 of each year, commencing on December 1, 2020. The 2027 Notes were scheduled to mature on June 1, 2027, unless earlier purchased by the Company, redeemed, or converted. On May 19, 2023, in connection with the completion of a private offering of $230.0 million aggregate principal amount of 2.875% convertible senior notes due 2029 described below, the Company repurchased and retired approximately $100.0 million in aggregate principal amount of its outstanding 2027 Notes. The remaining principal amount of $25.0 million 2027 Notes were settled on May 15, 2025 in a private transaction with all remaining 2027 Note holders for 1.6 million shares of the Company’s common stock and $5.4 million in cash. The settlement was accounted for as an induced conversion resulting in an inducement expense of approximately $0.7 million for the nine months ended September 30, 2025, which is included within “Other income (expense), net” on the Consolidated Statement of Operations, and a decrease to additional paid-in capital of $20.2 million on the Consolidated Balance Sheets.

2029 Notes

On May 19, 2023, the Company completed a private offering of $230.0 million of 2.875% convertible senior notes due 2029 (the “2029 Notes”). The Company received net proceeds of approximately $223.2 million, after deducting underwriting discounts and fees and expenses payable by the Company. Additionally, the Company used approximately $198.8 million of net proceeds from the offering to fund the cash portion of the 2025 Notes and 2027 Notes extinguishments described above and the remainder for general corporate purposes. The 2029 Notes bear interest at a rate of 2.875% per year, payable semiannually in arrears on June 1 and December 1 of each year, commencing on December 1, 2023. The 2029 Notes mature on June 1, 2029, unless earlier purchased by the Company, redeemed, or converted. The Company will settle any conversions of the 2029 Notes by paying cash up to the aggregate principal amount of the 2029 Notes to be converted, and paying or delivering either cash, shares of Company’s common stock, or a combination of cash and shares of common stock at the Company’s election, in respect of the remainder, if any, of the conversion obligation in excess of the aggregate principal amount of the 2029 Notes being converted.

The 2029 Notes are unsecured senior obligations of Veeco and rank senior in right of payment to any of Veeco’s subordinated indebtedness; equal in right of payment to all of Veeco’s unsecured indebtedness that is not subordinated; effectively subordinated in right of payment to any of Veeco’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally subordinated to all indebtedness and other liabilities (including trade payables) of Veeco’s subsidiaries.

The Company may redeem for cash, at its option, all or any portion of the outstanding 2029 Notes at any time on or after June 8, 2026, at a redemption price equal to 100% of the principal amount of such 2029 Notes to be redeemed plus accrued and unpaid interest to, but excluding, the redemption date, if the last reported sale price of the common stock has been at least 130% of the conversion price for the applicable series of 2029 Notes then in effect for at least 20 trading

days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides the redemption notice. Upon the Company’s notice of redemption, holders may elect to convert their 2029 Notes based on the conversion rates and criteria outlined below.

The 2029 Notes are convertible at the option of the holders upon the satisfaction of specified conditions and during certain periods as described below. The initial conversion rate is 34.21852 shares of the Company’s common stock per $1,000 principal amount, representing an initial effective conversion price of $29.22 per share of common stock. The conversion rate may be subject to adjustment upon the occurrence of certain specified events.

Holders may convert all or any portion of their 2029 Notes, in multiples ofone thousand dollar principal amount, at their option at any time prior to the close of business on the business day immediately preceding February 1, 2029, only under the following circumstances:

Holders may convert their 2029 Notes at any time, regardless of the foregoing circumstances, on February 1, 2029, until the close of business on the business day immediately preceding the maturity date.

The 2025, 2027, and 2029 Notes were recorded as a single unit within liabilities in the consolidated balance sheets as the conversion features within the Notes were not derivatives that require bifurcation and the Notes did not involve a substantial premium. Transaction costs of $1.9 million, $3.1 million, and $6.8 million incurred in connection with the issuance of the 2025 Notes, 2027 Notes, and 2029 Notes, respectively, were recorded as direct deductions from the related debt liabilities and recognized as non-cash interest expense using the effective interest method over the expected terms of the Notes.

The carrying value of the 2025 Notes, 2027 Notes, and 2029 Notes are as follows:

Total interest expense related to the 2025 Notes, 2027 Notes, and 2029 Notes is as follows:

The Company determined the 2029 Notes are Level 2 liabilities in the fair value hierarchy and had an estimated fair value at September 30, 2025 of $290.7 million.

Capped Call Transactions

In connection with the offering of the 2027 Notes, on May 13, 2020, the Company entered into privately negotiated capped call transactions (the “Capped Call Transactions”), pursuant to capped call confirmations, covering the initial underlying shares of the 2027 Notes of approximately 8.9 million shares, for an aggregate premium of $10.3 million. The Capped Call Transactions feature a $13.98 exercise price and a capped price of approximately $18.46 per share, and mature on June 1, 2027. The Capped Call Transactions are subject to certain adjustments under the terms of the capped call confirmations.

The Capped Call Transactions are separate transactions entered into by the Company with the capped call counterparties, are not part of the terms of the 2027 Notes and did not change the previous holders’ rights under the 2027 Notes. Previous holders of the 2027 Notes did not have any rights with respect to the Capped Call Transactions. The cost of the Capped Call Transactions is not expected to be tax-deductible as the Company did not elect to integrate the Capped Call Transactions into the 2027 Notes for tax purposes. The Company used a portion of the net proceeds from the offering of the 2027 Notes to pay for the Capped Call Transactions, and the cost of the Capped Call Transactions was recorded as a reduction of the Company’s additional paid-in capital in the accompanying consolidated financial statements.

Revolving Credit Facility

On December 16, 2021, the Company entered into a Loan and Security Agreement (the “Loan and Security Agreement”) providing for a senior secured revolving credit facility in an aggregate principal amount of $150 million including a $15 million letter of credit sublimit. The Loan and Security Agreement was subsequently amended to increase the aggregate principal amount to $225 million on August 2, 2024 (the “Third Amendment”), and $250 million on June 16, 2025 (the “Fourth Amendment”) (as amended to date, the “Credit Facility”). The Credit Facility matures on June 16, 2030, subject to a springing maturity date of March 2, 2029 upon the occurrence of certain liquidity events described in the Fourth Amendment. The Credit Facility is guaranteed by the Company’s direct material U.S. subsidiaries, subject to customary exceptions. Borrowings under the Credit Facility are secured by a first-priority lien on substantially all of the assets of the Company, subject to customary exceptions. Subject to certain conditions and the receipt of commitments from the lenders, the Loan and Security Agreement allows for revolving commitments under the Credit Facility to be increased by up to $100 million, with additional amounts available so long as the Secured Net Leverage Ratio (as defined in the Loan and Security Agreement) does not exceed 2.50 to 1.00. The existing lenders under the Credit Facility, are entitled, but not obligated, to provide such incremental commitments.

Borrowings will bear interest at a floating rate which can be, at the Company’s option based on certain conditions in the Loan and Security Agreement, either (a) an alternate base rate plus an applicable rate ranging from 0.25% to 1.00% or (b) a Secured Overnight Financing Rate (“SOFR”) (with a floor of 0.00%) for the specified interest period plus an applicable rate ranging from 1.25% to 2.00%, in each case, depending on the Company’s Secured Net Leverage Ratio (as defined in the Loan and Security Agreement). The Company will pay an unused commitment fee ranging from 0.20% to 0.30% based on unused capacity under the Credit Facility and the Company’s Secured Net Leverage Ratio. The Company may use the proceeds of borrowings under the Credit Facility to pay transaction fees and expenses, provide for its working capital needs and reimburse drawings under letters of credit and for other general corporate purposes.

The Loan and Security Agreement, contains customary affirmative covenants for transactions of this type, including, among others, the provision of financial and other information to the administrative agent, notice to the administrative agent upon the occurrence of certain material events, preservation of existence, maintenance of properties and insurance, compliance with laws, including environmental laws, the provision of additional guarantees, and an affiliate transactions covenant, subject to certain exceptions. The Loan and Security Agreement, contains customary negative covenants, including, among others, restrictions on the ability to merge and consolidate with other companies, incur indebtedness, refinance our existing convertible notes, grant liens or security interests on assets, make investments, acquisitions, loans, or advances, pay dividends, and sell or otherwise transfer assets.

The Loan and Security Agreement, contains financial maintenance covenants that require the Borrower to maintain an Interest Coverage Ratio (as defined in the Loan and Security Agreement) of not less than 3.00 to 1.00, a Total Net Leverage Ratio (as defined in the Loan and Security Agreement) of not more than 4.50 to 1.00, and a Secured Net Leverage Ratio (as defined in the Loan and Security Agreement) of not more than 3.00 to 1.00, in each case, tested at the end of each fiscal quarter. The Loan and Security Agreement, also provides for a number of customary events of default, including, among others: payment defaults to the lenders; voluntary and involuntary bankruptcy proceedings; covenant defaults; material inaccuracies of representations and warranties; certain change of control events; material money judgments; and other customary events of default. The occurrence of an event of default could result in the acceleration of obligations and the termination of lending commitments under the Loan and Security Agreement.

No amounts were outstanding under the Credit Facility as of September 30, 2025 or December 31, 2024.

Other Liabilities

Other Liabilities at September 30, 2025 and December 31, 2024 was approximately $3.8 million, which included medical and dental benefits for former executives, asset retirement obligations, contingent consideration, and tax liabilities.

Note 5 — Commitments and Contingencies

Leases

The Company’s operating leases primarily include real estate leases for properties used for manufacturing, R&D activities, sales and service, and administration, as well as certain equipment leases. Some leases may include options to renew for a period of up to 5 years, while others may include options to terminate the lease. The weighted average remaining lease term of the Company’s operating leases as of September 30, 2025 was 10 years, and the weighted average discount rate used in determining the present value of future lease payments was 5.7%.

The following table provides the maturities of lease liabilities at September 30, 2025:

Operating lease costs for the three and nine months ended September 30, 2025 were $1.2 million and $3.8 million, respectively, and $1.2 million and $3.6 million, respectively for the comparable 2024 period. Variable lease costs for the three and nine months ended September 30, 2025 were $0.3 million and $0.9 million, respectively and $0.3 million and $1.0 million, respectively for the comparable 2024 period. Additionally, the Company has an immaterial amount of short-term leases. Cash outflows from operating leases for the nine months ended September 30, 2025 and 2024 were $5.4 million and $5.0 million, respectively.

Receivable Purchase Agreement

The Company entered into a receivable purchase agreement with a financial institution to sell certain of its trade receivables from customers without recourse, up to $30.0 million at any point in time. Pursuant to this agreement, the Company soldno receivables for the three and nine months ended September 30, 2025, and $30.0 million was available under the agreement for additional sales of receivables as of September 30, 2025. The Company soldno receivables for the three months and $8.0 million for the nine months ended September 30, 2024. The net sale of accounts receivable under the agreement is reflected as a reduction of accounts receivable in the Company’s Consolidated Balance Sheet at the time of sale and any fees for the sale of trade receivables were not material for the periods presented.

Purchase Commitments

Veeco has purchase commitments of $128.2 million at September 30, 2025 to secure the rights to various assets and services to be used in the future in the normal course of business, substantially all of which become due within one year.

Bank Guarantees

Veeco has bank guarantees and letters of credit issued by a financial institution on its behalf as needed. At September 30, 2025, outstanding bank guarantees and standby letters of credit totaled $7.6 million, and unused bank guarantees and letters of credit of $35.1 million were available to be drawn upon.

Legal Proceedings

The Company is involved in various legal proceedings arising in the normal course of business. The Company does not believe that the ultimate resolution of these matters will have a material adverse effect on its consolidated financial position, results of operations, or cash flows.

Note 6 — Equity

Statement of Stockholders’ Equity

The following tables present the changes in Stockholders’ Equity:

Accumulated Other Comprehensive Income (“AOCI”)

The following table presents the changes in the balances of each component of AOCI, net of tax:

There were immaterial reclassifications from AOCI into net income for the three and nine months ended September 30, 2025 and 2024.

Note 7 — Share-based Compensation

Restricted share awards are issued to employees and to members of our board of directors that are subject to specified restrictions and a risk of forfeiture. The restrictions typically lapse overone tofour years and may entitle holders to dividends and voting rights. Other types of share-based compensation include performance share awards, performance share units, and restricted share units (collectively with restricted share awards, “restricted shares”), as well as options to purchase common stock.

Share-based compensation expense was recognized in the following line items in the Consolidated Statements of Operations for the three and nine months ended September 30, 2025 and 2024:

For the nine months ended September 30, 2025, equity activity related to non-vested restricted shares and performance shares was as follows:

Note 8 — Income Taxes

Income taxes are estimated for each of the jurisdictions in which the Company operates. Deferred income taxes reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting

purposes and the amounts used for income tax purposes, as well as the tax effect of carryforwards. Realization of net deferred tax assets is dependent on future taxable income.

At the end of each interim reporting period, the effective tax rate is aligned with expectations for the full year. This estimate is used to determine the income tax provision on a year-to-date basis and may change in subsequent interim periods.

Income before income taxes and income tax expense for the three and nine months ended September 30, 2025 and 2024 were as follows:

The Company’s income tax expense for the three and nine months ended September 30, 2025 was $1.3 million and $5.2 million, respectively, compared to $2.7 million and $5.7 million, respectively, for the comparable prior period.

For the three and nine months ended September 30, 2025, the effective tax rate was favorably impacted by the tax benefits related to Foreign-Derived Intangible Income and research and development tax credits. Additionally, the effective tax rate was also impacted by a discrete income tax expense resulting from the share-based compensation shortfall. For the three and nine months ended September 30, 2024, the effective tax rate was favorably impacted by the tax benefits related to Foreign-Derived Intangible Income and research and development tax credits. Additionally, the effective tax rate was lower than the U.S. statutory tax rate primarily relating to a discrete income tax benefit for share-based compensation windfall.

The One Big Beautiful Bill Act (“OBBBA”) was enacted on July 4, 2025, which contains a broad range of tax law changes affecting businesses. The provisions of the OBBBA have different effective dates where some are effective in 2025 and others not until 2026. The Company continues to evaluate the full effects of the legislation. Based on our analysis, these impacts have not had a material effect on Company’s financial position, results of operations or cash flow in the current fiscal year. The provisions effective in 2025 have been reflected in the Company’s consolidated operating results for the three and nine months ended September 30, 2025.

Note 9 — Segment Reporting and Geographic Information

The Company operates and measures its results inone operating segment and therefore hasone reportable segment: the development, manufacture, sales, and support of semiconductor and thin film process equipment primarily sold to make electronic devices. The accounting policies of thisone operating segment are the same as those described in the Company’s 2024 Form 10-K. The Chief Operating Decision Maker (“CODM”), the Chief Executive Officer, assesses segment performance and decides how to allocate resources based on net income that is reported on the Consolidated Statements of Operations. The measure of segment assets is reported on the Consolidated Balance Sheet as total assets. The Company does not have intra-entity sales or transfers. The CODM uses net income to evaluate income generated from segment assets (return on assets) in deciding whether to reinvest profits into the segment or into other parts of the Company, such as for acquisitions. Net income is used to monitor forecast versus actual results. The CODM also uses net income in competitive analysis by benchmarking the Company’s competitors. The competitive analysis along with the monitoring of forecasted versus actual results are used in assessing performance of the segment. The Company regularly provides management reports to the CODM on a consolidated expense basis which includes actuals, forecasted, and budgeted information. These reports are similar to the Company’s consolidated financial statements.

There are no additional expenses categories and amounts that meet the definition of significant expense items that are regularly provided to the CODM and included in the reported measure of net income.

Veeco serves the following four end-markets:

Semiconductor

The Semiconductor market refers to early process steps in logic and memory applications where silicon wafers are processed. There are many different process steps in forming patterned wafers, such as deposition, etching, masking, and doping, where the microchips are created but remain on the silicon wafer.

Note 10 — Subsequent Events

Merger Agreement with Axcelis Technologies, Inc.

On September 30, 2025, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Axcelis Technologies, Inc. a Delaware corporation (“Axcelis”), and Victory Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Axcelis (“Merger Sub”). Pursuant to the Merger Agreement, and subject to the satisfaction or waiver of the conditions specified therein, Merger Sub will merge with and into Veeco (the “Merger”), with Veeco surviving as a wholly-owned subsidiary of Axcelis. The Merger Agreement was unanimously approved by Veeco’s board of directors (except forone (1) independent director who serves on the Axcelis board of directors as well and thus recused himself) and is subject to certain customary closing conditions, including the approval by the stockholders of each company and various regulatory approvals. Subject to the satisfaction or (to the extent permissible) waiver of such conditions, the Merger is currently expected to close in the second half of 2026.

Under the terms of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of Company common stock issued and outstanding immediately prior to the Effective Time (other than shares owned by Axcelis, the Company, Merger Sub, or their wholly-owned subsidiaries) will be converted into the right to receive 0.3575 newly issued shares of Axcelis common stock (the “Axcelis Common Stock”). No fractional shares of Axcelis will be issued in the Merger, and the Company stockholders will receive cash in lieu of fractional shares as part of the merger consideration. Following the Merger, Axcelis’ common stockholders are expected to own approximately 58.4% of the shares of Axcelis Common Stock on a fully diluted basis, and the Company’s common stockholders will own approximately 41.6%.

The Merger Agreement contains customary representations, warranties, and covenants, including restrictions on the conduct of business prior to closing and provisions regarding the treatment of the Company’s outstanding equity awards and employee benefits. The Merger Agreement may be terminated under certain circumstances, including by mutual consent of the Company and Axcelis or if the Merger is not consummated by September 30, 2026 (subject to automatic extensions until as late as June 30, 2027 under certain conditions with respect to the receipt of regulatory approvals).

If the board of directors of either party makes an Adverse Recommendation Change, as defined in the Merger Agreement, the other party shall have the right to terminate the Merger Agreement, and the non-terminating party will be

required to pay the other party the following termination fee: (i) if the non-terminating party is Axcelis, a termination fee of $108,700,000; and (ii) if the non-terminating party is Veeco, a termination fee of $77,500,000. Each party may also be required to pay such termination fee if such party enters into a competing proposal within twelve months of termination of the Merger Agreement under certain circumstances. In addition, if the Merger Agreement is terminated by a party as a result of the other party’s failure to obtain stockholder approval, or is terminated by a party due to the other party’s breach of the Merger Agreement that would result in a failure of an applicable closing condition (subject to the applicable cure period set forth in the Merger Agreement), then the non-terminating party will be required to pay a fixed expense reimbursement amount of $15,000,000.

The Company incurred approximately $2.6 million in legal, accounting, consulting fees and employee-related costs in connection with the proposed Merger during the three and nine months ended September 30, 2025, included as part of Selling, General, and Administrative expenses on the Consolidated Statement of Operations.

Additional information regarding the Merger Agreement and the proposed Merger is included in the Company’s Current Report on Form 8-K filed with the SEC on October 1, 2025.
