When used in this Report, the words such as “expects,” “anticipates,” “plans,” “believes,” “scheduled,” “estimates,” and variations of these words and similar expressions are intended to identify forward-looking statements. Discussions containing such forward-looking statements may be found in Part I - Items 1, 2, and 3 hereof, as well as within this Report generally. ​ In addition, the preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Although these estimates and assumptions are based on knowledge of current events and planned actions to be undertaken in the future, they may ultimately differ from actual results. Operating results for the three months ended March 31 , 2026 are not necessarily indicative of the results that may be expected for the year ending December 31, 2026. All estimates and assumptions are subject to a number of risks and uncertainties that could cause actual results to differ materially from these estimates and assumptions. ​ Forward-looking statements in this discussion include, but are not limited to, those regarding anticipated growth and trends in our business and markets, including trends related to artificial intelligence and high-performance computing, industry outlooks and demand drivers, our investment and growth strategies, our development of new products and technologies, our business outlook for the current and future periods, and other statements that are not historical facts.

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, 2025 (“2025 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 2026 interim quarters end on March 29, June 28, and September 27, and the 2025 interim quarters end on March 30, June 29, and September 28. 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. ​ 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 10 Merger for additional information. ​ 8 Table of Contents 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 months ended March 31, 2026 and 2025 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended March 31, ​ ​ ​ ​ ​ ​ 2026 ​ ​ ​ 2025 ​ ​ ​ ​ ​ ​ ​ ​ (in thousands, except per share amounts) ​ Numerator: ​ ​ ​ ​ ​ ​ ​ ​ Net income (loss) ​ $ ( 324 ) ​ $ 11,947 ​ ​ Interest expense associated with convertible notes ​ ​ — ​ ​ 253 ​ ​ Net income (loss) available to common shareholders ​ $ ( 324 ) ​ $ 12,200 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Denominator: ​ ​ ​ ​ ​ ​ ​ ​ Basic weighted average shares outstanding ​ 60,414 ​ 57,753 ​ ​ Effect of potentially dilutive share-based awards ​ ​ — ​ ​ 693 ​ ​ Dilutive effect of convertible notes ​ — ​ 1,788 ​ ​ Diluted weighted average shares outstanding ​ 60,414 ​ 60,234 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income (loss) per common share: ​ ​ ​ ​ ​ ​ ​ ​ Basic ​ $ ( 0.01 ) ​ $ 0.21 ​ ​ Diluted ​ $ ( 0.01 ) ​ $ 0.20 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Potentially dilutive shares excluded from the diluted calculation as their effect would be antidilutive ​ ​ 232 ​ ​ 954 ​ ​ Maximum potential shares to be issued for settlement of convertible senior notes excluded from the diluted calculation as their effect would be antidilutive ​ ​ N/A ​ ​ 174 ​ ​ ​ ​ 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. ​ 9 Table of Contents 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 March 31, 2026 and December 31, 2025: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Level 1 ​ ​ ​ Level 2 ​ ​ ​ Level 3 ​ ​ ​ Total ​ ​ (in thousands) March 31, 2026 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash equivalents ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Certificate of deposits and time deposits ​ $ 76,124 ​ $ — ​ $ — ​ $ 76,124 Money market cash ​ ​ 20,174 ​ ​ — ​ ​ — ​ ​ 20,174 Total ​ $ 96,298 ​ $ — ​ $ — ​ $ 96,298 Short-term investments ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. treasuries ​ $ 65,522 ​ $ — ​ $ — ​ $ 65,522 Government agency securities ​ ​ — ​ ​ 52,653 ​ ​ — ​ ​ 52,653 Corporate debt ​ ​ — ​ ​ 85,621 ​ ​ — ​ ​ 85,621 Total ​ $ 65,522 ​ $ 138,274 ​ $ — ​ $ 203,796 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash equivalents ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Certificate of deposits and time deposits ​ $ 63,893 ​ $ — ​ $ — ​ $ 63,893 Money market cash ​ ​ 15,327 ​ ​ — ​ ​ — ​ ​ 15,327 Total ​ $ 79,220 ​ $ — ​ $ — ​ $ 79,220 Short-term investments ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. treasuries ​ $ 77,110 ​ $ — ​ $ — ​ $ 77,110 Government agency securities ​ ​ — ​ ​ 53,488 ​ ​ — ​ ​ 53,488 Corporate debt ​ ​ — ​ ​ 96,165 ​ ​ — ​ ​ 96,165 Total ​ $ 77,110 ​ $ 149,653 ​ $ — ​ $ 226,763 ​ There were no transfers between fair value measurement levels during the three months ended March 31, 2026. ​ 10 Table of Contents At March 31, 2026 and December 31, 2025, the amortized cost and fair value of available-for-sale securities consist of: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross ​ ​ ​ Gross ​ ​ ​ ​ ​ ​ Amortized ​ Unrealized ​ Unrealized ​ Estimated ​ ​ Cost ​ Gains ​ Losses ​ Fair Value ​ ​ (in thousands) March 31, 2026 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. treasuries ​ $ 65,743 ​ $ 11 ​ $ ( 232 ) ​ $ 65,522 Government agency securities ​ ​ 52,784 ​ ​ 15 ​ ​ ( 146 ) ​ ​ 52,653 Corporate debt ​ ​ 85,839 ​ ​ 9 ​ ​ ( 227 ) ​ ​ 85,621 Total ​ $ 204,366 ​ $ 35 ​ $ ( 605 ) ​ $ 203,796 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. treasuries ​ $ 77,106 ​ $ 52 ​ $ ( 48 ) ​ $ 77,110 Government agency securities ​ ​ 53,473 ​ ​ 50 ​ ​ ( 35 ) ​ ​ 53,488 Corporate debt ​ 96,144 ​ ​ 86 ​ ​ ( 65 ) ​ 96,165 Total ​ $ 226,723 ​ $ 188 ​ $ ( 148 ) ​ $ 226,763 ​ Available-for-sale securities in a loss position at March 31, 2026 and December 31, 2025 consist of: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Continuous Loss Position ​ ​ ​ for Less than 12 Months ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross ​ ​ ​ ​ ​ Estimated ​ Unrealized ​ ​ ​ Fair Value ​ Losses ​ ​ ​ ​ (in thousands) March 31, 2026 ​ ​ ​ ​ ​ ​ ​ U.S. treasuries ​ $ 44,358 ​ $ ( 232 ) ​ Government agency securities ​ ​ 42,772 ​ ​ ( 146 ) ​ Corporate debt ​ 70,790 ​ ( 227 ) ​ Total ​ $ 157,920 ​ $ ( 605 ) ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 ​ ​ ​ ​ ​ ​ ​ U.S. treasuries ​ $ 37,609 ​ $ ( 48 ) ​ Government agency securities ​ ​ 24,028 ​ ​ ( 35 ) ​ Corporate debt ​ 45,675 ​ ( 65 ) ​ Total ​ $ 107,312 ​ $ ( 148 ) ​ ​ The contractual maturities of securities classified as available-for-sale at March 31, 2026 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2026 ​ ​ Amortized ​ Estimated ​ ​ Cost ​ Fair Value ​ ​ ​ (in thousands) Due in one year or less ​ $ 131,982 ​ $ 131,876 Due after one year through two years ​ ​ 70,488 ​ 70,051 Due after two years through three years ​ ​ 1,896 ​ ​ 1,869 Total ​ $ 204,366 ​ $ 203,796 ​ 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.

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.

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. ​ 15 Table of Contents The carrying value of the 2029 Notes is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2026 ​ ​ December 31, 2025 ​ ​ ​ Principal Amount ​ ​ Unamortized transaction costs ​ ​ Net carrying value ​ ​ Principal Amount ​ ​ Unamortized transaction costs ​ ​ Net carrying value ​ ​ ​ (in thousands) 2029 Notes ​ $ 230,000 ​ $ ( 3,747 ) ​ $ 226,253 ​ $ 230,000 ​ $ ( 3,991 ) ​ $ 226,009 Net carrying value ​ $ 230,000 ​ $ ( 3,747 ) ​ $ 226,253 ​ $ 230,000 ​ $ ( 3,991 ) ​ $ 226,009 ​ Total interest expense related to the 2025 Notes, 2027 Notes, and 2029 Notes is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended March 31, ​ ​ ​ ​ ​ 2026 ​ ​ ​ 2025 ​ ​ (in thousands) ​ Cash Interest Expense ​ ​ ​ ​ ​ ​ Coupon interest expense - 2025 Notes ​ $ — ​ $ 39 ​ Coupon interest expense - 2027 Notes ​ ​ — ​ ​ 234 ​ Coupon interest expense - 2029 Notes ​ ​ 1,653 ​ ​ 1,653 ​ Non-cash Interest Expense ​ ​ ​ ​ ​ Amortization of debt discount/transaction costs- 2025 Notes ​ ​ — ​ ​ 4 ​ Amortization of debt discount/transaction costs- 2027 Notes ​ ​ — ​ ​ 18 ​ Amortization of debt discount/transaction costs- 2029 Notes ​ ​ 244 ​ ​ 235 ​ Total Interest Expense ​ $ 1,897 ​ $ 2,183 ​ ​ The Company determined the 2029 Notes are Level 2 liabilities in the fair value hierarchy and had an estimated fair value at March 31, 2026 of $ 328.4 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.

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 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 March 31, 2026 or December 31, 2025. ​ Other Liabilities ​ Other Liabilities at March 31, 2026 and December 31, 2025 was approximately $ 4.7 million and $ 3.9 million, respectively, which included merger costs, medical and dental benefits for former executives, asset retirement obligations, 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.

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. ​ Tariffs ​ On February 20, 2026, the U.S. Supreme Court issued a decision invalidating tariffs imposed under the International Emergency Economic Powers Act. The Company is continuing to evaluate the impact of these developments on its business and financial statements, and has initiated various processes and procedures to file claims for refunds for these previously paid duties. However, as the tariff landscape continues to shift and evolve, there remains uncertainty as to the amount that will ultimately be refunded, the Company’s ability to collect such refunds, and the timing of such refunds, and as such, the Company has not recorded any adjustments to its financial statements related to these potential refunds. While the Company continues to implement measures to mitigate tariff - related cost pressures, these actions may not fully offset increased costs in future periods. ​ ​ Note 6 — Equity ​ Statement of Stockholders’ Equity ​ The following tables present the changes in Stockholders’ Equity: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Accumulated ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Additional ​ ​ ​ ​ Other ​ ​ ​ ​ ​ Common Stock ​ Paid-in ​ Accumulated ​ Comprehensive ​ ​ ​ ​ ​ Shares ​ Amount ​ Capital ​ Deficit ​ Income ​ Total ​ ​ (in thousands) Balance at December 31, 2025 60,389 ​ $ 604 ​ $ 1,306,176 ​ $ ( 423,065 ) ​ $ 1,794 ​ $ 885,509 Net income (loss) — ​ — ​ — ​ ( 324 ) ​ — ​ ( 324 ) Other comprehensive income (loss), net of tax — ​ — ​ — ​ — ​ ( 472 ) ​ ( 472 ) Share-based compensation expense — ​ — ​ 8,511 ​ — ​ — ​ 8,511 Net issuance under employee stock plans ​ 643 ​ ​ 6 ​ ​ ( 9,568 ) ​ ​ — ​ ​ — ​ ​ ( 9,562 ) Balance at March 31, 2026 61,032 ​ $ 610 ​ $ 1,305,119 ​ $ ( 423,389 ) ​ $ 1,322 ​ $ 883,662 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Accumulated ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Additional ​ ​ ​ ​ Other ​ ​ ​ ​ ​ Common Stock ​ Paid-in ​ Accumulated ​ Comprehensive ​ ​ ​ ​ ​ Shares ​ Amount ​ Capital ​ Deficit ​ Income ​ Total ​ ​ (in thousands) Balance at December 31, 2024 56,828 ​ $ 569 ​ $ 1,227,134 ​ $ ( 458,455 ) ​ $ 1,522 ​ $ 770,770 Net income — ​ — ​ — ​ 11,947 ​ — ​ 11,947 Other comprehensive income (loss), net of tax — ​ — ​ — ​ — ​ 108 ​ 108 Share-based compensation expense — ​ — ​ 9,208 ​ — ​ — ​ 9,208 Settlement of the 2025 Notes ​ 1,104 ​ ​ 11 ​ ​ 26,489 ​ ​ — ​ ​ — ​ ​ 26,500 Net issuance under employee stock plans ​ 360 ​ ​ 3 ​ ​ ( 6,678 ) ​ ​ — ​ ​ — ​ ​ ( 6,675 ) Balance at March 31, 2025 58,292 ​ $ 583 ​ $ 1,256,153 ​ $ ( 446,508 ) ​ $ 1,630 ​ $ 811,858 ​ 19 Table of Contents Accumulated Other Comprehensive Income (“AOCI”) ​ The following table presents the changes in the balances of each component of AOCI, net of tax: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Unrealized ​ ​ ​ ​ ​ ​ ​ Gains (Losses) ​ ​ ​ ​ ​ Foreign ​ on Available- ​ ​ ​ ​ ​ Currency ​ for-Sale ​ ​ ​ ​ ​ ​ ​ Translation ​ ​ ​ Securities ​ ​ ​ Total ​ ​ (in thousands) Balance - December 31, 2025 ​ $ 1,855 ​ $ ( 61 ) ​ $ 1,794 Other comprehensive income (loss) ​ — ​ ( 472 ) ​ ( 472 ) Balance - March 31, 2026 ​ $ 1,855 ​ $ ( 533 ) ​ $ 1,322 ​ There were immaterial reclassifications from AOCI into net income for the three months ended March 31, 2026 and 2025. ​ 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 over one to four 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 months ended March 31, 2026 and 2025: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended March 31, ​ ​ ​ ​ ​ 2026 ​ ​ ​ 2025 ​ ​ ​ ​ ​ (in thousands) ​ Cost of sales $ 1,511 $ 1,343 Research and development ​ ​ 2,506 ​ ​ 3,048 ​ Selling, general, and administrative ​ ​ 4,494 ​ ​ 4,817 ​ Total ​ $ 8,511 ​ $ 9,208 ​ ​ For the three months ended March 31, 2026, equity activity related to non-vested restricted shares and performance shares was as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ Average ​ ​ Number of ​ Grant Date ​ ​ Shares ​ Fair Value ​ ​ (in thousands) ​ ​ ​ Balance - December 31, 2025 ​ 2,551 ​ $ 28.89 Granted ​ 1,113 ​ ​ 30.79 Performance award adjustments ​ 117 ​ ​ 32.25 Vested ​ ( 942 ) ​ ​ 27.70 Forfeited ​ ( 32 ) ​ ​ 23.41 Balance - March 31, 2026 ​ 2,807 ​ $ 30.25 ​ ​ 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. 20 Table of Contents ​ 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 months ended March 31, 2026 and 2025 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended March 31, ​ ​ ​ ​ 2026 ​ ​ ​ 2025 ​ ​ (in thousands, except percentages) Income (loss) before income taxes ​ $ ( 1,483 ) ​ $ 14,984 ​ Income tax expense (benefit) $ ( 1,159 ) $ 3,037 ​ Effective tax rate ​ 78.15 % ​ 20.27 % ​ ​ The Company’s income tax benefit for the three months ended March 31, 2026 was $ 1.2 million, compared to an income tax expense of $ 3.0 million for the comparable prior period. ​ For the three months ended March 31, 2026, the effective tax rate was higher than the U.S. statutory tax rate primarily related to a discrete income tax benefit for share-based compensation windfall. For the three months ended March 31, 2025, the effective tax rate was in line with the U.S. statutory tax rate, which included a $ 1.5 million tax expense related to share-based compensation shortfalls, partially offset by tax benefits related to Foreign-Derived Intangible Income and research and development tax credits. ​ Note 9 — Segment Reporting and Geographic Information ​ The Company operates and measures its results in one operating segment and therefore has one 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 this one operating segment are the same as those described in the Company’s 2025 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.

Looking ahead, industry analysts are forecasting long-term growth of the industry, driven by secular growth trends such as artificial intelligence, high-performance computing, mobile connectivity, and the electrification of the automotive industry. Additionally, government investments in the Semiconductor industry are projected to accelerate global spending in next-generation technologies. ​ Growth in the Semiconductor industry, coupled with increasing technological complexity of Semiconductor chips, are expected to drive long-term growth in Wafer Fab Equipment (“WFE”) spending. In an effort to improve chip performance, optimize power consumption, and reduce costs, today’s most advanced Semiconductor manufacturers are shrinking device geometries, investing in more complex transistor designs such as Gate-All-Around and exploring 3D 24 Table of Contents architectures. As a result, growth of the WFE market is forecasted to keep pace with long-term growth of the Semiconductor industry, which we believe should benefit semiconductor capital equipment providers, including Veeco. ​ Veeco’s technologies are at the forefront of enabling new technical innovations in the manufacturing of high-performance AI chips and High-Bandwidth Memory (“HBM”). We continue to invest in new technologies to expand our Serviceable Available Market (“SAM”) to a broad range of new applications. ​ Semiconductor Market ​ Semiconductor revenue comprised 69% of first quarter total revenue primarily driven by system shipments of our Laser Spike Annealing (“LSA”), and our Advanced Packaging, wet processing and lithography products. Semiconductor revenue decreased 12% from the comparable prior period due to a reduction in China revenue of 74% partially offset by increases in Rest of APAC revenue of 38% and United States revenue of 69%. ​ In the logic market, our annealing solutions continue to gain traction at advanced node customers. Our LSA platform is production tool of record at all three Tier 1 logic customers. Our next-generation Nanosecond Annealing (“NSA”) system is progressing through evaluations at Tier 1 logic customers. Our NSA tool addresses critical low-thermal budget applications such as contact annealing, 3D device integration and materials modification. These evaluations are advancing well, and we are anticipating an additional evaluation shipment to a third Tier 1 logic customer in the coming months. ​ In the memory market, we continue to expand our presence as current and future roadmap requirements for Dynamic-Random-Access Memory (“DRAM”) drive the need for low-thermal-budget anneals used in high-band-width memory and vertical DRAM devices. We are the production tool of record at a leading high-bandwidth memory customer, and we continue to make progress with another LSA evaluation system at a second Tier 1 DRAM customer, with potential for pilot line orders in the second half of 2026. ​ We also have two Ion Beam Deposition “IBD300” systems under evaluation at leading DRAM memory customers. Our IBD300 system provides Veeco with another opportunity to expand our SAM to advanced node applications where low resistance films are critical. These initial systems are being evaluated for advanced memory applications, such as DRAM bitline metallization. ​ The ongoing adoption of EUV Lithography for advanced node semiconductor manufacturing continues to drive demand for our Ion Beam Deposition EUV system for mask blanks. Leading logic and memory customers expect EUV and High Numerical Aperture (“High-NA”) lithography to be integral to their future roadmaps. Our Ion Beam Deposition technology is a key enabler of the EUV mask blank Multiple Layer Mirror deposition. Our product roadmap is well positioned as the industry adopts next-generation High-NA EUV lithography, and we are expanding our EUV related business to EUV pellicles which are increasingly being used to improve the productivity of EUV steps. Our IBD-EUV system is also used to form the high-transparency membrane used in pellicles. ​ In Advanced Packaging (“AP”), our wet processing systems are used for several applications, and we continue to see strong demand driven by Heterogenous Integration and 2.5D and 3D Packaging for AI and high-performance computing. In the first quarter, we had an increase in orders for our wet processing systems from leading OSAT customers, supporting high-volume manufacturing of next-generation AI accelerators using 2.5D AP architectures. ​ Looking ahead, we anticipate growth in the semiconductor market in leading-edge investment driven by AI and high-performance computing. ​ Compound Semiconductor Market ​ Compound Semiconductor revenue increased by 31% in the first quarter from the comparable prior year period, comprising 12% of total revenue. In the Compound Semiconductor market, we have a broad portfolio of products which are gaining momentum due to a significant inflection point within the industry with AI data center infrastructure build-out. 25 Table of Contents ​ The AI build-out is impacting interconnects where there is a shift from copper wiring to pluggables and co-packaged optics as data centers demand higher-speed and lower-power communication. Within this space, Indium Phosphide (“InP”) lasers are a major component as the light-source for pluggables and co-packaged optics for next-generation AI infrastructure. As the industry transitions toward future capacity requirements, we believe this represents growth opportunity of approximately $2.0 billion dollars over the next several years. Our technology plays a critical role within the manufacturing of InP lasers and order demand is greatly accelerating across multiple of our products. These products include Lumina MOCVD Arsenide Phosphide batch platform, Wafer Etch and Wafer Storm for etching and metal lift-off, and importantly our Spector ion beam deposition for the laser diode facet coatings. Our Spector ion beam deposition system, designed for the critical laser facet coating step, is essential to the process. Veeco is the market leader in ion beam deposition and is highly differentiated from traditional approaches such as E-beam evaporation, ion assisted deposition or physical vapor deposition (“PVD”). Compared with other approaches, the Spector Ion Beam Deposition (“IBD”) tool delivers low-loss optical films with tight control of thickness, uniformity, and reflectivity – precision that is required for anti-reflective and high-reflective facet coatings on InP. We received orders over $250 million dollars from multiple customers for our MOCVD, wet processing and ion beam deposition tools to support the manufacturing of InP lasers with deliveries starting in 2026 and significantly accelerating in 2027. A large portion of these orders is from a leading supplier of next-generation 800-gig and 1.6-terabit optical transceivers for hyperscale customers, for our Spector IBD systems. This significant order activity underscores the long-term value of our ion beam deposition technology leadership and our expanding role in this rapidly growing market. We have long-standing partnerships with our customers, spanning more than two decades, and we are well positioned across our multiple differentiated products to meet their growing needs in silicon photonics. ​ Additionally, there are other photonics applications driving growth for our products in this space, including red MircoLEDs, low earth orbit solar cells and augmented / virtual reality applications. ​ Lastly, our Propel300mm GaN on Si product continues to be a strong long-term driver tied to AI data center power efficiency, electrification, and high-power density applications. At a leading power IDM customer, we have an evaluation for our Propel300 system in place, and we received a pilot-line order for a multi-chamber system at the end of 2025. As this leading customer ramps and finalizes long-term capacity plans, there is potential for additional system orders in the second half of 2026 for delivery in 2027. ​ We expect our compound semiconductor market to grow as AI, power efficiency and advanced connectivity continue to reshape the industry. ​ ​ Data Storage Market ​ Data Storage market revenue increased by 52% in the first quarter from the comparable prior year period, comprising 6% of total revenue. We address the Data Storage market with sales of our Ion Beam technology and wet process systems driven by demand for cloud and AI data centers. We have seen increase in order activity in the back-half of 2025 and increased customer utilization rates as customers gain traction in new technologies like Heat Assisted-Magnetic-Recording (“HAMR”). Orders received in the third and fourth quarter of 2025 for our ion beam and wet processing equipment from demand for cloud and AI data centers, will drive revenue growth in 2026, principally in the second half. Customer engagement remains strong with our business fully booked in 2026 and extending into 2027. ​ Scientific & Other Market ​ Scientific & Other market revenue decreased by 9% in the first quarter from the comparable prior year period, comprising 13% of total revenue. Sales in the Scientific & Other market are largely driven by sales to government-funded laboratories, universities, and research institutions. We address the Scientific & Other market with several technologies, including MBE, ALD, MOCVD, Wet Processing, and IBD/IBE, which support diverse R&D and niche low-volume production applications. ​ ​ 26 Table of Contents Results of Operations ​ For the three months ended March 31, 2026 and 2025 ​ The following table presents revenue and expense line items reported in our Consolidated Statements of Operations for the indicated periods in 2026 and 2025 and the period-over-period dollar and percentage changes for those line items. Our results of operations are reported as one business segment, represented by our single operating segment. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, ​ ​ Change ​ ​ ​ 2026 ​ ​ 2025 ​ ​ Period to Period ​ ​ ​ (dollars in thousands) ​ Net sales ​ ​ ​ $ 158,341 ​ ​ ​ 100% ​ ​ $ 167,292 ​ ​ ​ 100% ​ ​ $ (8,951) ​ ​ ​ (5)% ​ ​ ​ ​ Cost of sales ​ 102,513 65% ​ ​ 98,825 59% ​ ​ 3,688 4% ​ ​ Gross profit ​ 55,828 35% ​ ​ 68,467 41% ​ ​ (12,639) (18)% ​ ​ Operating expenses, net: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Research and development ​ 29,875 19% ​ ​ 28,514 17% ​ ​ 1,361 5% ​ ​ Selling, general, and administrative ​ 26,016 16% ​ ​ 25,028 15% ​ ​ 988 4% ​ ​ Amortization of intangible assets ​ 705 0% ​ ​ 821 0% ​ ​ (116) (14)% ​ ​ Merger costs ​ 2,012 1% ​ ​ — 0% ​ ​ 2,012 * ​ ​ Other operating expense (income), net ​ (122) (0)% ​ ​ (44) (0)% ​ ​ (78) * ​ ​ Total operating expenses, net ​ 58,486 37% ​ ​ 54,319 32% ​ ​ 4,167 8% ​ ​ Operating income (loss) ​ (2,658) (2)% ​ ​ 14,148 8% ​ ​ (16,806) * ​ ​ Interest income, net ​ 1,175 1% ​ ​ 836 0% ​ ​ 339 41% ​ ​ Income (loss) before income taxes ​ (1,483) (1)% ​ ​ 14,984 9% ​ ​ (16,467) (110)% ​ ​ Income tax expense (benefit) ​ (1,159) (1)% ​ ​ 3,037 2% ​ ​ (4,196) (138)% ​ ​ Net income (loss) ​ $ (324) (0)% ​ ​ $ 11,947 7% ​ ​ $ (12,271) (103)% ​ ​ * Not meaningful Net Sales The following is an analysis of sales by market and by region: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, ​ ​ Change ​ ​ ​ 2026 ​ ​ 2025 ​ ​ Period to Period ​ ​ ​ (dollars in thousands) ​ Sales by end-market ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Semiconductor ​ $ 109,042 69% ​ ​ $ 123,823 74% ​ ​ $ (14,781) (12)% ​ ​ Compound Semiconductor ​ 18,808 12% ​ ​ 14,397 9% ​ ​ 4,411 31% ​ ​ Data Storage ​ 10,213 6% ​ ​ 6,705 4% ​ ​ 3,508 52% ​ ​ Scientific & Other ​ 20,278 13% ​ ​ 22,367 13% ​ ​ (2,089) (9)% ​ ​ Total ​ $ 158,341 100% ​ ​ $ 167,292 100% ​ ​ $ (8,951) (5)% ​ ​ Sales by geographic region ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ United States ​ $ 32,225 20% ​ ​ $ 24,062 15% ​ ​ $ 8,163 34% ​ ​ EMEA ​ 15,784 10% ​ ​ 12,337 7% ​ ​ 3,447 28% ​ ​ China ​ ​ 19,956 ​ 13% ​ ​ ​ 70,892 ​ 42% ​ ​ ​ (50,936) (72)% ​ ​ Rest of APAC ​ 90,364 57% ​ ​ 59,976 36% ​ ​ 30,388 51% ​ ​ Rest of World ​ 12 - ​ ​ 25 - ​ ​ (13) (52)% ​ ​ Total ​ $ 158,341 100% ​ ​ $ 167,292 100% ​ ​ $ (8,951) (5)% ​ ​ ​ Sales decreased for the three months ended March 31, 2026 against the comparable prior year period driven by a decrease in sales in the Semiconductor, and Scientific & Other markets, partially offset by an increase in sales in the 27 Table of Contents Compound Semiconductor and Data Storage markets. By geography, sales decreased in the China region, partially offset by increased sales in the Rest of APAC, United States, and EMEA regions. Sales in the Rest of APAC region for the three months ended March 31, 2026 included sales in Taiwan and Japan of $65.6 million and $9.2 million, respectively. Sales in the Rest of APAC region for the three months ended March 31, 2025 included sales in Japan and Taiwan of $32.5 million, and $14.0 million respectively. In light of the global nature of our business, we are impacted by conditions in the various countries in which we and our customers operate, including the recent tariff and trade dynamics. We expect there will continue to be year-to-year variations in our future sales distribution across markets and geographies. ​ Gross Profit ​ For the three months ended March 31, 2026, gross profit decreased against the comparable prior period primarily due to a decrease in sales volume, as well as a decrease in gross margins. Gross margins decreased principally due to unfavorable product mix and higher logistics costs. Additionally other factors will cause our gross margins to fluctuate each period, including the impact of the evolving tariffs landscape, which may include potential refunds on previously paid tariffs, newly implemented tariffs, or changes to existing tariffs. ​ Research and Development ​ The markets we serve are characterized by continuous technological development and product innovation, and we invest in various research and development initiatives to maintain our competitive advantage and achieve our growth objectives. Research and development expenses increased for the three months ended March 31, 2026 against the comparable prior period due to an increase in personnel-related expenses. ​ Selling, General, and Administrative ​ Selling, general, and administrative expenses increased for the three months ended March 31, 2026 against the comparable prior period due to personnel-related expenses. Merger Costs ​ During the three months ended March 31, 2026, we incurred an additional $2.0 million in legal, accounting, consulting fees and employee-related costs in connection with the proposed Merger. ​ Interest Income (Expense) ​ We recorded net interest income of $1.2 million for the three months ended March 31, 2026, compared to net interest income of $0.8 million for the comparable prior year period. The increase in net interest income was primarily due to reduced interest expense on the 2025 Notes as they matured on January 15, 2025 and the 2027 Notes that were settled on May 15, 2025. ​ Income Taxes ​ Our tax benefit for the three months ended March 31, 2026, was $1.2 million, compared to $3.0 million of tax expense for the comparable prior period. For the three months ended March 31, 2026, the effective tax rate was higher than the U.S. statutory tax rate primarily related to a discrete income tax benefit for share-based compensation windfall. For the three months ended March 31, 2025, the effective tax rate was in line with the U.S. statutory tax rate, which included a $1.5 million tax expense related to share-based compensation shortfalls, partially offset by tax benefits related to Foreign-Derived Intangible Income and research and development tax credits. ​ 28 Table of Contents Liquidity and Capital Resources ​ Our cash and cash equivalents, restricted cash, and short-term investments are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, ​ December 31, ​ ​ ​ ​ 2026 ​ ​ ​ 2025 ​ ​ (in thousands) Cash and cash equivalents ​ $ 179,535 ​ $ 163,466 Short-term investments ​ 203,796 ​ 226,763 Total ​ $ 383,331 ​ $ 390,229 ​ At March 31, 2026 and December 31, 2025, cash and cash equivalents of $34.0 million and $23.6 million, respectively, were held outside the United States. As of March 31, 2026, we had $27.5 million of accumulated undistributed earnings generated by our non-U.S. subsidiaries for which the U.S. tax has previously been provided. Approximately $13.4 million of undistributed earnings will be subject to foreign withholding taxes if distributed back to the United States and we accrued $1.4 million for foreign withholding taxes for the undistributed earnings. ​ We believe that our projected cash flow from operations, combined with our cash and short-term investments, will be sufficient to meet our projected working capital requirements, contractual obligations, and other cash flow needs for the next twelve months, including scheduled principal and interest payments on our convertible senior notes, purchase commitments, and payments required under our operating leases. ​ A summary of the cash flow activity for the three months ended March 31, 2026 and 2025 is as follows: ​ Cash Flows from Operating Activities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, ​ ​ ​ ​ ​ ​ ​ 2026 ​ ​ ​ 2025 ​ ​ ​ ​ ​ (in thousands) ​ Net income (loss) ​ $ (324) ​ $ 11,947 ​ Non-cash items: ​ ​ ​ ​ ​ ​ ​ Depreciation and amortization ​ 5,037 ​ 5,035 ​ Non-cash interest expense ​ 244 ​ 257 ​ Deferred income taxes ​ (1,088) ​ 1,567 ​ Share-based compensation expense ​ 8,511 ​ 9,208 ​ Changes in operating assets and liabilities ​ (4,445) ​ (8,022) ​ Net cash provided by (used in) operating activities ​ $ 7,935 ​ $ 19,992 ​ ​ Net cash provided by operating activities was $7.9 million for the three months ended March 31, 2026 and was due to net loss of $0.3 million and adjustments for non-cash items of $12.7 million, partially offset by a decrease in cash flow from changes in operating assets and liabilities of $4.4 million. The changes in operating assets and liabilities were largely attributable to an increase in accounts receivables, and inventories, partially offset by an increase in contract liabilities, accrued expenses, and accounts payable. ​ Cash Flows from Investing Activities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, ​ ​ ​ ​ ​ 2026 ​ ​ ​ 2025 ​ ​ ​ ​ ​ (in thousands) ​ Capital expenditures ​ $ (5,103) ​ $ (6,755) ​ Changes in investments, net ​ 22,794 ​ 21,278 ​ Net cash provided by (used in) investing activities ​ $ 17,691 ​ $ 14,523 ​ ​ The cash provided by investing activities during the three months ended March 31, 2026 was primarily attributable to net cash provided for investment activity, partially offset by capital expenditures. The cash provided by investing activities 29 Table of Contents during the three months ended March 31, 2025 was primarily attributable to net cash used for investment activity, partially offset by capital expenditures. Cash Flows from Financing Activities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, ​ ​ ​ ​ ​ 2026 ​ ​ ​ 2025 ​ ​ ​ ​ ​ (in thousands) ​ Settlement of equity awards, net of withholding taxes ​ $ (9,558) ​ $ (5,276) ​ Net cash provided by (used in) financing activities ​ $ (9,558) ​ $ (5,276) ​ ​ The cash used in financing activities for the three months ended March 31, 2026 was related to cash used to settle taxes related to employee equity programs, offset by cash received under the Employee Stock Purchase Plan. The cash used in financing activities for the three months ended March 31, 2025 was related to cash used to settle taxes related to employee equity programs, partially offset by cash received under the Employee Stock Purchase Plan. ​ Convertible Senior Notes ​ We have $230.0 million outstanding principal balance of convertible senior notes that bear interest at a rate of 2.875% per year, payable semiannually in arrears on June 1 and December 1 of each year, and mature on June 1, 2029, unless earlier purchased by the Company, redeemed, or converted. ​ We believe that we have sufficient capital resources and cash flows from operations to support scheduled interest payments on this debt. In addition, in June 2025, we increased the total funds available to us through our revolving credit facility from $225 million to $250 million and extended the maturity until June 16, 2030, subject to a springing maturity date of March 2, 2029. The Company has no immediate plans to draw down on the facility. Interest under the facility is variable based on the Company’s secured net leverage ratio and is expected to bear interest based on SOFR plus a range of 125 to 200 basis points, if drawn. There is a yearly commitment fee of 20 to 30 basis points, based on the Company’s secured net leverage ratio, charged on the unused portion of the Facility. ​ In connection with the Merger, the convertible senior notes will be assumed by Axcelis. ​ Contractual Obligations and Commitments ​ We have commitments under certain contractual arrangements to make future payments for goods and services. These contractual arrangements secure the rights to various assets and services to be used in the future in the normal course of business. We expect to fund these contractual arrangements with cash generated from operations in the normal course of business. ​ Item 3. Quantitative and Qualitative Disclosures about Market Risk ​ Interest Rate Risk ​ Our exposure to market rate risk for changes in interest rates primarily relates to our investment portfolio. We centrally manage our investment portfolios considering investment opportunities and risks, tax consequences, and overall financing strategies. Our investment portfolio includes fixed-income securities with a fair value of approximately $203.8 million at March 31, 2026. These securities are subject to interest rate risk and, based on our investment portfolio at March 31, 2026, a 100 basis point increase in interest rates would result in a decrease in the fair value of the portfolio of $1.5 million. While an increase in interest rates may reduce the fair value of the investment portfolio, we will not realize the losses in the Consolidated Statements of Operations unless the individual fixed-income securities are sold prior to recovery or the loss is determined to be other-than-temporary. ​ 30 Table of Contents Currency Exchange Risk ​ We conduct business on a worldwide basis and, as such, a portion of our revenues, earnings, and net investments in foreign affiliates is exposed to changes in currency exchange rates. The economic impact of currency exchange rate movements is complex because such changes are often linked to variability in real growth, inflation, interest rates, governmental actions, and other factors. These changes, if material, could cause us to adjust our financing and operating strategies. Consequently, isolating the effect of changes in currency does not incorporate these other important economic factors. ​ Changes in currency exchange rates could affect our foreign currency denominated monetary assets and liabilities and forecasted cash flows. We may enter into monthly forward derivative contracts from time to time with the intent of mitigating a portion of this risk. We only use derivative financial instruments in the context of hedging and not for speculative purposes and have not historically designated our foreign exchange derivatives as hedges. Accordingly, changes in fair value from these contracts are recorded as “Other, net” in our Consolidated Statements of Operations. We execute derivative transactions with highly rated financial institutions to mitigate counterparty risk. ​ Our net sales to customers located outside of the United States represented approximately 80% and 86% of our total net sales for the three months ended March 31, 2026 and 2025, respectively. We expect that net sales to customers outside the United States will continue to represent a large percentage of our total net sales. Our sales denominated in currencies other than the U.S. dollar represented approximately 2% and 6% of total net sales for the three months ended March 31, 2026 and 2025, respectively. ​ A 10% change in foreign exchange rates would have an immaterial impact on the consolidated results of operations since most of our sales outside the United States are denominated in U.S. dollars. ​ Item 4. Controls and Procedures ​ Evaluation of Disclosure Controls and Procedures ​ Our principal executive and financial officers have evaluated and concluded that our disclosure controls and procedures are effective as of March 31, 2026. The disclosure controls and procedures are designed to ensure that the information required to be disclosed in this report filed under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and is accumulated and communicated to our principal executive and financial officers as appropriate to allow timely decisions regarding required disclosure. ​ Changes in Internal Control Over Financial Reporting ​ During the quarter ended March 31, 2026, there were no changes in internal control that have materially affected or are reasonably likely to materially affect internal control over financial reporting. ​ PART II—OTHER INFORMATION ​ Item 1. 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. ​ Item 1A. Risk Factors ​ Information regarding risk factors appears in the Safe Harbor Statement at the beginning of this quarterly report on Form 10-Q, in Part I — Item 1A of our 2025 Form 10-K.
