NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in millions, except per share data)

**(1)** **Basis of Presentation**

The terms "MKS" and the "Company" refer to MKS Inc., formerly known as MKS Instruments, Inc., and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The interim financial data as of June 30, 2025, and for the three and six months ended June 30, 2025, are unaudited; however, in the opinion of MKS, the interim data includes all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods. The condensed consolidated balance sheet presented as of December 31, 2024 has been derived from the consolidated audited financial statements as of that date. The unaudited condensed consolidated financial statements presented herein have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the "SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the MKS Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 25, 2025.

The preparation of these unaudited condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates and judgments, including those related to revenue recognition, inventory valuation, warranty costs, pension plan valuations, stock-based compensation expense, intangible assets, goodwill, long-lived assets, income taxes and derivatives. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. As a result of rounding, there may be immaterial differences in amounts presented and certain calculations may not sum to the total number expressed in each category or tie to a corresponding schedule.

The Company has three reportable segments: the Vacuum Solutions Division ("VSD"), the Photonics Solutions Division ("PSD") and the Materials Solutions Division ("MSD") as described in Note 15.

**(2)** **Recent Accounting Pronouncements**

<u>Income Taxes (Topic 740): Improvements to Income Tax Disclosures</u>

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"), which focuses on the rate reconciliation and income taxes paid. ASU 2023-09 requires a public business entity ("PBE") to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. For PBEs, the new standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. An entity may apply the amendments prospectively by providing the revised disclosures for the period ending December 31, 2025 and continuing to provide the pre-ASU disclosures for the prior periods or may apply the amendments retrospectively by providing the revised disclosures for all periods presented. The Company is currently evaluating the impact on its consolidated financial statement disclosures; however, adoption will not impact its consolidated balance sheets, cash flows or income statements.

<u>Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses</u>

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses ("ASU 2024-03"), which requires public companies to disclose, in interim and annual reporting periods, additional disaggregated information about certain income statement expense line items in the notes to financial statements. The amendments in ASU 2024-03 are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after

**(4)** **Fair Value Measurements**

In accordance with the provisions of fair value accounting, a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability and defines fair value based upon an exit price model.

The fair value measurement guidance establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance describes three levels of inputs that may be used to measure fair value:

Level 1 Quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted

(in millions, except per share data)

prices that are traded less frequently than exchange-traded instruments or securities or derivative contracts that are valued using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data.

Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the Company categorizes such assets and liabilities based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Assets and liabilities of the Company are measured at fair value on a recurring basis as of June 30, 2025, and are summarized as follows:

<u>Other Fair Value Disclosures</u>

The estimated carrying value and fair value of the Company's debt were as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | June 30, 2025 | June 30, 2025 | December 31, 2024 | December 31, 2024 |
|  | Carrying Value | Fair Value | Carrying Value | Fair Value |
| Term Loan Facility | $3102 | $3112 | $3249 | $3262 |
| Convertible Notes | 1400 | 1385 | 1400 | 1357 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total | $4502 | $4497 | $4649 | $4619 |

---

The estimated fair value of the Company's Term Loan Facility, as defined and further described in Note 8, was determined using available market information based on recent trades or activity of debt instruments with substantially similar risks, terms and maturities, which fall within Level 2 under the fair value hierarchy. The estimated fair value of the Company's Convertible Notes, as defined and further described in Note 8, was determined based on the last traded price of the Convertible Notes for the period ended June 30, 2025, and falls under Level 2 of the fair value hierarchy.

<u>Money Market Funds</u>

Money market funds are cash and cash equivalents and are classified within Level 1 of the fair value hierarchy.

(in millions, except per share data)

<u>Pension and Deferred Compensation Plan Assets</u> 

The pension and deferred compensation plan assets represent investments in mutual funds, exchange traded funds, government securities and other time deposits. These investments are set aside for retirement benefits for employees of certain of the Company's subsidiaries.

<u>Derivatives</u>

As a result of the Company's global operating activities and variable interest rate borrowings, the Company is exposed to market risks from changes in foreign currency exchange rates and interest rates, which may adversely affect its operating results and financial position. When appropriate, the Company uses derivative financial instruments to minimize its exposure to risks from foreign currency exchange rate and interest rate fluctuations. The principal market in which the Company executes its foreign currency and interest rate contracts is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants are typically large commercial banks. The contracts are valued using broker quotations or market transactions.

**(5)** **Derivatives and Net Investment Hedge**

<u>Foreign Exchange Forward Contracts</u>

The Company hedges a portion of its forecasted foreign currency-denominated intercompany sales of inventory and certain of its foreign subsidiaries' operating expenses, over a maximum period of twenty-four months, using foreign exchange forward contracts accounted for as cash-flow hedges. To the extent these derivatives are effective in offsetting the variability of the hedged cash flows, and otherwise meet the hedge accounting criteria, changes in the derivatives' fair value are not included in current earnings but are included in other comprehensive income ("OCI") in stockholders' equity. These changes in fair value will subsequently be reclassified into earnings as applicable, when the forecasted transaction occurs. To the extent that a previously designated hedging transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded in earnings in the period it occurs. The cash flows resulting from foreign exchange forward contracts are classified in the condensed consolidated statements of cash flows as part of cash flows from operating activities.

The Company also enters into foreign exchange forward contracts to hedge against certain monetary asset and liability accounts on the condensed consolidated balance sheet to mitigate the risk associated with certain foreign currency transactions in the ordinary course of business. These derivatives are not designated as cash flow hedging instruments and gains or losses from these derivatives are recorded immediately in other expense (income), net.

The following table summarizes the net notional values of foreign exchange forward contracts outstanding:

---

| | | |
|:---|:---|:---|
|  | June 30, 2025 | December 31, 2024 |
| *Designated as cash flow hedging instruments:* |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Foreign exchange forward contracts - cash flow hedges | $40 | $74 |
| *Not designated as cash flow hedging instruments:* |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Foreign exchange forward contracts - balance sheet hedges | $256 | $154 |

---

As of June 30, 2025, the South Korean won, Canadian dollar and Japanese yen were the largest notional contracts designated as cash flow hedging instruments. As of December 31, 2024, the Japanese yen and South Korean won were the largest notional contracts designated as cash flow hedging instruments.

As of June 30, 2025, the Euro, Chinese yuan and British pound were the largest notional contracts for balance sheet hedges not designated as cash flow hedging instruments. As of December 31, 2024, the Chinese yuan and British pound were the largest notional contracts for balance sheet hedges not designated as cash flow hedging instruments.

<u>Net Investment Hedge</u>

On January 1, 2023, the Company designated certain Euro-denominated debt as a net investment hedge to hedge a portion of its net investments in certain of its entities with functional currencies denominated in the Euro. On January 22, 2024, the Company prepaid its USD Tranche A in full using, in part, a €250 incremental borrowing under its Euro Tranche B, each as defined and further described in Note 8. On January 22, 2024, the Company designated the additional €250 of its Euro Tranche B as a net investment hedge. As of June 30, 2025, the total principal amount outstanding under its Euro Tranche B

------

MKS INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in millions, except per share data)

was €591 and the entire balance was designated as a net investment hedge. As of December 31, 2024, the total principal amount outstanding under its Euro Tranche B was €596 and the entire balance was designated as a net investment hedge. For these net investment hedges, the Company records foreign currency remeasurement gains and losses within a component of OCI. Recognition in earnings of amounts previously recorded in accumulated OCI is limited to circumstances such as complete or substantially complete liquidation or sale of the net investment in the hedged foreign operations.

<u>Interest Rate Agreements</u> 

The Company has various interest rate swap agreements, which are cash-flow hedges, maturing through January 31, 2029, that exchange a one-month forward-looking term rate based on the variable secured overnight financing rate ("Term SOFR") paid on the outstanding balance of its USD Term Loan Facility, as defined and further described in Note 8, to a fixed rate. The notional value of the agreements was $1,900 and $2,600 as of June 30, 2025 and December 31, 2024, respectively. The Company acquired USD London Interbank Offered Rate interest rate cap agreements as a result of its acquisition of Atotech Limited ("Atotech") on August 17, 2022 (the "Atotech Acquisition"), and utilized these agreements to offset Term SOFR on its Term Loan Facility. The interest rate cap agreements expired on January 31, 2024.

The interest rate swaps are recorded at fair value on the balance sheet and changes in the fair value are recognized in OCI. To the extent these arrangements are no longer effective hedges, the hedging relationship will be discontinued and changes in the fair value of the hedging instruments from the last assessment period that were effective up to the current period will be recorded immediately in earnings. Amounts previously recorded in OCI will remain in OCI and will be reclassified to earnings when the interest payments impact consolidated earnings. If the Company determines that the interest payments are unlikely to occur, amounts previously recorded in OCI will be reclassified to earnings immediately. Changes in the fair value of interest rate caps were recorded immediately in earnings, as the Company did not designate these instruments as hedges and therefore these instruments did not qualify for hedge accounting. The cash flows resulting from interest rate agreements were classified in cash flows from operating activities in the condensed consolidated statements of cash flows.

The following table summarizes the net (losses) gains on derivatives designated as cash flow hedging instruments:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | Three Months Ended<br>June 30, | Three Months Ended<br>June 30, | Six Months Ended<br>June 30, | Six Months Ended<br>June 30, |
|  | 2025 | 2024 | 2025 | 2024 |
| *Foreign exchange forward contracts-cash flow hedges:* |  |  |  |  |
| Net (losses) gains recognized in OCI, net of tax | $(3) | $2 | $(4) | $8 |
| Net gains (losses) reclassified from accumulated OCI into cost of revenues | $2 | $2 | $4 | $1 |
| *Interest rate hedges:* |  |  |  |  |
| Net (losses) gains recognized in OCI, net of tax | $(6) | $— | $(21) | $25 |
| Net gains (losses) reclassified from accumulated OCI into interest expense | $5 | $16 | $12 | $33 |

---

The Company expects an immaterial amount to be reclassified from accumulated OCI into cost of revenues during the next 12 months related to foreign exchange forward contracts. The Company expects a net gain of approximately $9 to be reclassified from accumulated OCI into interest expense during the next 12 months related to interest rate hedges.

The following table summarizes the net (losses) gains on derivatives not designated as hedging instruments:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | Three Months Ended<br>June 30, | Three Months Ended<br>June 30, | Six Months Ended<br>June 30, | Six Months Ended<br>June 30, |
|  | 2025 | 2024 | 2025 | 2024 |
| Net (losses) gains recognized in other expense (income), net | $(5) | $1 | $(4) | $(3) |

---

The interest rate caps resulted in a reduction of $3 to interest expense in the six months ended June 30, 2024.

Derivative instruments are subject to master netting arrangements. However, the Company has elected to record these contracts on a gross basis in the condensed consolidated balance sheet. The location and fair value amounts of derivative instruments reported in the condensed consolidated balance sheet is disclosed in Note 4.

<u>Credit Facilities</u>

In connection with the completion of the Atotech Acquisition, on August 17, 2022 (the "Effective Date") the Company entered into a credit agreement with JPMorgan Chase Bank, N.A., as administrative agent and collateral agent, Barclays Bank PLC, and the lenders from time to time party thereto (the "Credit Agreement"). The Credit Agreement initially provided for (i) a senior secured term loan facility comprised of three tranches: a $1,000 loan (as further refinanced and otherwise modified as described herein, the "USD Tranche A"), a $3,600 loan (as further refinanced and otherwise modified as described herein, the "USD Tranche B") and a €600 loan (as further refinanced and otherwise modified as described herein, the "Euro Tranche B" and together with the USD Tranche A and the USD Tranche B, the "Term Loan Facility"), each of which were borrowed in full on the Effective Date, and (ii) a senior secured revolving credit facility of $500 (as further increased and otherwise modified as described herein, the "Revolving Facility" and, together with the Term Loan Facility, the "Credit Facilities"), with the commitments under each of the foregoing facilities subject to increase from time to time subject to certain conditions. The proceeds of the Term Loan Facility were used on the Effective Date, among other things, to fund a portion of the consideration payable in connection with the Atotech Acquisition and to refinance the existing term loan and revolving credit facilities of the Company and certain indebtedness of Atotech. The Company has entered into five amendments to the Credit Agreement since the Effective Date (as amended, the "Amended Credit Agreement"), including most recently the Fifth Amendment (as defined below).

As of June 30, 2025, after giving effect to all amendments and repayments prior to such date, the Amended Credit Agreement provided for (i) the Term Loan Facility comprised of two tranches: the USD Tranche B in an outstanding principal amount of $2,409 and the Euro Tranche B in an outstanding principal amount of €591 and (ii) the Revolving Facility with aggregate commitments of $675.

As of June 30, 2025, borrowings under the Credit Facilities bore interest at a rate per annum equal to, at the Company's option, any of the following, plus, in each case, an applicable margin: (a) with respect to the Revolving Facility and the USD Tranche B, (x) a base rate determined by reference to the highest of (1) the federal funds effective rate plus 0.50%, (2) the prime rate quoted in The Wall Street Journal, or (3) a forward-looking term rate based on Term SOFR (plus an applicable credit spread adjustment) for an interest period of one month, plus 1.00%; and (y) a Term SOFR rate (plus an applicable credit spread adjustment) for the interest period relevant to such borrowing, subject to a rate floor of (I) with respect to the USD Tranche B, 0.50% and (II) with respect to the Revolving Facility, 0.0%; and (b) with respect to the Euro Tranche B, a Euro Interbank Offered Rate ("EURIBOR") rate determined by reference to the costs of funds for Euro deposits for the interest period relevant to such borrowing adjusted for certain additional costs, subject to a EURIBOR rate floor of 0.0%. As of June 30, 2025, the applicable margins for borrowings under the Credit Facilities were (i) under the USD Tranche B, 1.00% with respect to base rate borrowings and 2.00% with respect to Term SOFR borrowings, (ii) under the Euro Tranche B, 2.50% and (iii) under the Revolving Facility, 1.50% with respect to base rate borrowings and 2.50% with respect to Term SOFR borrowings.

In addition to paying interest on outstanding principal under the Credit Facilities, the Company is required to pay a commitment fee in respect of the unutilized commitments under the Revolving Facility. The commitment fee is subject to adjustment based on the Company's first lien net leverage ratio as of the end of the preceding fiscal quarter. The Company must also pay customary letter of credit fees and agency fees. As of June 30, 2025, the commitment fee was 0.25% per annum.

On January 24, 2025 (the "Fifth Amendment Effective Date"), the Company entered into the Fifth Amendment to Credit Agreement (the "Fifth Amendment"), pursuant to which the Company (i) refinanced its existing USD Tranche B loan and Euro Tranche B loan with a new $2,529 USD Tranche B loan and a new €596 Euro Tranche B loan, (ii) decreased the applicable margin for the USD Tranche B from 2.25% to 2.00% with respect to Term SOFR borrowings and from 1.25% to 1.00% with respect to base rate borrowings and (iii) decreased the applicable margin for the Euro Tranche B from 2.75% to 2.50%. The repriced USD Tranche B loan and Euro Tranche B loan were issued without original issue discount. In connection with the execution of the Fifth Amendment, the Company paid customary fees and expenses to JPMorgan Chase Bank, N.A.

On January 24, 2025, concurrently with the effectiveness of the Fifth Amendment, the Company made a voluntary prepayment of $100 principal amount to the USD Tranche B loan.

On June 27, 2025, the Company made a voluntary prepayment of $100 principal amount to the USD Tranche B loan.

On August 1, 2025, the Company made a voluntary prepayment of $100 principal amount to the USD Tranche B loan.

Under the Amended Credit Agreement, the Company is required to prepay outstanding term loans, subject to certain exceptions, with portions of its annual excess cash flow as well as with the net cash proceeds of certain of its asset sales, certain casualty and condemnation events and the incurrence or issuances of certain debt. If at any time the aggregate amount of outstanding loans, unreimbursed letter of credit drawings and undrawn letters of credit under the Revolving Facility exceeds the aggregate commitments under the Revolving Facility, the Company is required to repay outstanding loans and/or cash collateralize letters of credit, with no reduction of the commitment amount.

The Company may voluntarily prepay outstanding loans under the Credit Facilities from time to time, subject to certain conditions, without premium or penalty other than customary "breakage" costs with respect to Term SOFR or EURIBOR loans; provided, however, that subject to certain exceptions, if on or prior to the date that is six months after the Fifth Amendment Effective Date, the Company prepays any loans under the USD Tranche B or the Euro Tranche B in connection with a repricing transaction, the Company must pay a prepayment premium of 1.00% of the aggregate principal amount of the loans so prepaid. Additionally, the Company may voluntarily reduce the unutilized portion of the commitment amount under the Revolving Facility.

The Company is required to make scheduled quarterly payments each equal to approximately $10 with respect to the USD Tranche B and approximately €2 with respect to the Euro Tranche B, in each case with the balance due thereunder on the seventh anniversary of the Effective Date. There is no scheduled amortization under the Revolving Facility. Any principal amount outstanding under the Revolving Facility is due and payable in full on the fifth anniversary of the Effective Date.

All obligations under the Credit Facilities are guaranteed by certain of the Company's wholly-owned domestic subsidiaries and are required to be guaranteed by certain of the Company's future wholly-owned domestic subsidiaries, and are secured by substantially all of the Company's assets and the assets of such subsidiaries, subject to certain exceptions and exclusions.

The USD Tranche B and the Euro Tranche B are not subject to financial maintenance covenants.

The Amended Credit Agreement contains customary representations and warranties, covenants and provisions relating to events of default. If an event of default occurs, the lenders under the Credit Facilities will be entitled to take various actions, including the acceleration of amounts due under the Credit Facilities and all actions permitted to be taken by a secured creditor. As of June 30, 2025, the Company was in compliance with all covenants under the Amended Credit Agreement.

As of June 30, 2025, the weighted average interest rate of the Term Loan Facility was 5.9%. The Revolving Facility has a maturity date in August 2027 while the USD Tranche B and Euro Tranche B have a maturity date in August 2029. As of June 30, 2025, there were no borrowings under the Revolving Facility.

<u>Convertible Notes</u>

On May 16, 2024, the Company completed a private offering of $1,400 aggregate principal amount of its convertible senior notes due 2030 (the "Convertible Notes").

The net proceeds from the offering were approximately $1,374 after deducting the initial purchasers' discounts and commissions and estimated offering expenses paid by the Company. The Company used approximately $167 of the net proceeds from the offering to pay the cost of the capped call transactions described below. The Company used the remaining net proceeds from the offering to repay approximately $1,206 in borrowings outstanding under the USD Tranche B, together with accrued interest, as well as for general corporate purposes. As a result of the repayment, the Company recorded a $38 loss on extinguishment of debt in the three months ended June 30, 2024.

*Indenture and the Convertible Notes*

On May 16, 2024, the Company entered into an indenture (the "Indenture") with respect to the Convertible Notes with U.S. Bank Trust Company, National Association, as trustee (the "Trustee"). Under the Indenture, the Convertible Notes are senior unsecured obligations of the Company and bear interest at a coupon rate of 1.25% per annum, with interest payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2024. The Convertible Notes will mature on June 1, 2030, unless earlier converted, redeemed or repurchased in accordance with their terms.

Subject to certain conditions, on or after June 5, 2027, the Company may redeem for cash all or any portion of the Convertible Notes at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, if the last reported sale price of the Company's common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the trading day immediately preceding the date the notice of redemption is sent.

The conversion rate for the Convertible Notes is initially 6.4799 shares of the Company's common stock per one thousand dollars principal amount of the Convertible Notes, which is equivalent to an initial conversion price of approximately $154.32 per share. The conversion rate is subject to adjustment upon the occurrence of certain events.

Upon conversion, the Company will pay cash up to the aggregate principal amount of the Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of 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 its conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted. Prior to March 1, 2030, noteholders may convert all or any portion of their Convertible Notes only upon the occurrence of certain events and during certain periods, and thereafter, at any time until the second scheduled trading day immediately preceding the maturity date.

If the Company undergoes a fundamental change (as defined in the Indenture) prior to the maturity date of the Convertible Notes, holders may require the Company to repurchase for cash all or any portion of their Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The Indenture contains customary terms and covenants, including that upon certain events of default that are occurring and continuing, either the Trustee or the holders of at least 25% in aggregate principal amount of the outstanding Convertible Notes may declare 100% of the principal of, and accrued and unpaid interest, if any, on, all the Convertible Notes to be due and payable.

As of June 30, 2025, the Convertible Notes were classified as a long-term liability, net of issuances costs, on the condensed consolidated balance sheet. The Convertible Notes were issued at par and costs associated with the issuance of the Convertible Notes are amortized to interest expense over the contractual term of the Convertible Notes. As of June 30, 2025, the effective interest rate of the Convertible Notes was 1.56%.

*Capped Call Transactions*

On May 13, 2024, in connection with the pricing of the Convertible Notes, and on May 14, 2024, in connection with the exercise in full by the initial purchasers of their option to purchase additional Convertible Notes, the Company entered into privately negotiated capped call transactions with certain of the initial purchasers of the Convertible Notes or their respective affiliates and other financial institutions. The capped call transactions are expected generally to reduce the potential dilution to the Company's common stock upon conversion of any Convertible Notes and/or offset any cash payments that the Company is required to make in excess of the principal amount of any converted Convertible Notes, as the case may be, with such reduction and/or offset subject to a cap initially equal to $237.42 per share, which represents a premium of 100% over the last reported sale price of $118.71 per share of the Company's common stock on The Nasdaq Global Select Market on May 13, 2024, and is subject to customary adjustments under the terms of the capped call transactions.

The Company evaluated the capped call transactions and determined that they should be accounted for separately from the Convertible Notes. The cost of $167 to purchase the capped call transactions was recorded as a reduction to additional paid-in capital in the condensed consolidated balance sheet as the capped call transactions are indexed to the Company's own stock and met the criteria to be classified in stockholders' equity.

The Company's interest expense was as follows:

**(9)** **Product Warranties**

The Company provides for the estimated costs to fulfill customer warranty obligations upon the recognition of the related revenue. The Company's warranty obligations are affected by shipment volume, product failure rates, utilization levels, material usage and supplier warranties on parts delivered to the Company. Should actual product failure rates, utilization levels, material usage, or supplier warranties on parts differ from the Company's estimates, revisions to the estimated warranty liability would be required. The Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers.

Product warranty activities were as follows:

**(11)** **Income Taxes**

The Company's effective tax rates for the three and six months ended June 30, 2025 were 13.6% and 13.0%, respectively. The Company's effective tax rates for the three and six months ended June 30, 2025 were lower than the U.S. statutory tax rate primarily due to the U.S. deduction for foreign derived intangible income ("FDII") and research and development credits, partially offset by foreign withholding taxes and a waiver of deductions related to U.S. base erosion payments.

The Company's effective tax rates for the three and six months ended June 30, 2024 were (3.6%) and 8.9%, respectively. The Company's effective tax rates for the three and six months ended June 30, 2024 were lower than the U.S. statutory tax rate primarily due to the U.S. deduction for FDII and research and development tax credits, partially offset by an increase in foreign withholding taxes and U.S. base erosion and anti-abuse tax.

On July 4, 2025, the One Big Beautiful Bill Act (the "OBBBA") was enacted into law. The OBBBA includes significant changes to the U.S. tax code, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The OBBBA has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company is currently assessing the impact of the OBBBA on its consolidated financial statements.

| &nbsp;&nbsp;&nbsp;&nbsp;Shares used in net income per common share - diluted | 67.4 | 67.5 | 67.5 | 67.5 |
| Net income per common share: |  |  |  |  |

| &nbsp;&nbsp;&nbsp;&nbsp;Diluted | $0.92 | $0.33 | $1.69 | $0.55 |

---

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

Diluted net income per common share is computed by dividing the diluted net income available to common stockholders by the weighted-average number of shares of common stock and potentially dilutive shares of common stock outstanding during the period. The dilutive effect of equity awards is calculated based on the average stock price for the relevant period, using the treasury stock method. In periods in which a net loss is recognized, the impact of restricted stock units ("RSUs") is not included as they are antidilutive. The dilutive effect of the Convertible Notes is calculated under the if-converted method.

For each of the three and six months ended June 30, 2025, there were 0.2 RSUs that were antidilutive and excluded from the computation of diluted weighted-average shares. For each of the three and six months ended June 30, 2024, the Company had an immaterial quantity of RSUs that were antidilutive and excluded from the computation of diluted weighted-average shares. Shares of common stock that would have been issued if the Convertible Notes had been converted are not included in the calculation of diluted net income per common share as the Company's share price during these periods was below the initial conversion price and inclusion would be antidilutive.

**(13)** **Stock-Based Compensation**

<u>Equity Incentive Plans</u>

Stock-based awards include (i) time-based RSUs, (ii) performance-based RSUs based on the achievement of adjusted EBITDA targets, (iii) performance-based RSUs based on the Company's total stockholder return relative to a group of peers over a three-year performance period and (iv) employee stock purchase plan rights. The Company grants RSUs to employees and directors under the 2022 Stock Incentive Plan and issues shares of common stock under the 2014 Employee Stock Purchase Plan pursuant to its employee stock purchase program.

The following tables present the activity for the RSUs:

<u>Share Repurchase Program</u>

On July 25, 2011, the Company's Board of Directors approved a share repurchase program for the repurchase of up to an aggregate of $200 of its outstanding common stock from time to time in open market purchases, privately negotiated transactions or through other appropriate means. The timing and quantity of any shares repurchased will depend upon a variety of factors, including business conditions, stock market conditions and business development activities, including, but not limited to, merger and acquisition opportunities. These repurchases may be commenced, suspended or discontinued at any time without prior notice. Any repurchased shares are held by the Company as authorized but unissued shares.

During the six months ended June 30, 2025, the Company repurchased approximately 0.5 shares of its common stock for total consideration of $45. During the three months ended June 30, 2025 and the three and six months ended June 30, 2024, there were no repurchases of common stock. The Company has repurchased approximately 3.1 shares of common stock for approximately $172 pursuant to the program since its adoption.

<u>Cash Dividends</u>

Holders of the Company's common stock are entitled to receive dividends when and if they are declared by the Company's Board of Directors. During each of the first and second quarters of 2025 and 2024, the Company's Board of Directors declared a cash dividend of $0.22 per share, each of which totaled $30 for both the six months ended June 30, 2025 and 2024.

On August 4, 2025, the Company's Board of Directors declared a quarterly cash dividend of $0.22 per share to be paid on September 5, 2025 to stockholders of record as of August 25, 2025.

Future dividend declarations, if any, as well as the record and payment dates for such dividends, are subject to the final determination of the Company's Board of Directors.

**(15)** **Business Segment, Geographic Area and Product Information**

<u>Reportable Segments and Products</u>

The Company's Chief Operating Decision Maker (the "CODM"), which is the Company's Chief Executive Officer, utilizes financial information to make decisions about allocating resources and assessing performance for the entire Company, which is used in the decision-making process to assess performance. The Company has a diverse base of customers across its three end markets, semiconductor, electronics and packaging, and specialty industrial. Segment gross margin is the primary measure used by the CODM to assess segment performance and allocate resources. Gross margin, among other measures, is utilized when making decisions about capital and personnel allocations across segments.

The Company has three reportable segments, VSD, PSD and MSD as described below.

VSD delivers foundational technology solutions to semiconductor manufacturing, electronics and packaging and specialty industrial applications. VSD products are derived from the Company's core competencies in vacuum technologies, including pressure measurement and control, flow measurement and control, gas and vapor delivery, gas composition analysis, electronic control technology, reactive gas generation and delivery, power generation and delivery, and fiber optic temperature and position sensing.

PSD provides a broad range of solutions including lasers, beam measurement and profiling, precision motion control, vibration isolation systems, photonics instruments, opto-mechanical components, optical elements, laser-based systems for flexible printed circuit board ("PCB") laser processing, laser-based systems for high-density interconnect PCB and package substrate manufacturing.

MSD develops leading process and manufacturing technologies for advanced surface modification, electroless and electrolytic plating, and surface finishing. Applying a comprehensive systems-and-solutions approach, MSD's portfolio includes chemistry, equipment and services for innovative and high-technology applications in the electronics and packaging and specialty industrial markets.

The Company derives its segment results directly from the manner in which results are reported in its management reporting system. The accounting policies that the Company uses to derive reportable segment results are substantially the same as those used for external reporting purposes. The Company groups its product offerings by its reportable segments, VSD, PSD, and MSD. For each reportable segment, the Company also provides services relating to the maintenance and repair of its products, installation services and training. Unallocated corporate expenses represent those costs not specifically related to the operations of each segment and are managed separately at the corporate level and primarily relate to labor costs of global functions such as supply chain, quality control and operations.

The following tables set forth the details of gross profit by reportable segment and the reconciliation to income before income taxes:

***Semiconductor Market***

We are a critical solutions provider for semiconductor manufacturing. Our products are used in major semiconductor processing steps, such as deposition, etching, cleaning, lithography, metrology, and inspection. The semiconductor industry continually faces new challenges, as products become smaller, more powerful and highly mobile. Ultra-thin layers, smaller critical dimensions, new materials, 3D structures, and the ongoing need for higher yield and productivity drive the need for tighter process measurement and control, all of which we support. We believe we are the broadest critical subsystem provider in the wafer fabrication equipment ecosystem and address over 85% of the market. We characterize our broad and unique offering as Surround the Wafer® to reflect the technology enablement we provide across almost every major process in semiconductor manufacturing today.

The semiconductor market is subject to rapid demand shifts, which are difficult to predict, and we cannot be certain as to the timing or extent of future demand or any future softening in the semiconductor capital equipment industry. In addition to these rapid demand shifts, the semiconductor capital equipment industry has recently been subject to significant trade restrictions, especially in key markets, including China.

For the three months ended June 30, 2025, net revenues in our semiconductor market increased by $19 million, or 5%, compared to the prior quarter due to an increase in sales of our semiconductor capital equipment at VSD related to strength in

------

logic and foundry applications, upgrades to support existing NAND memory production and increased service revenues. In addition, net revenues in the semiconductor market were also favorably impacted by foreign currency exchange rates as the U.S. dollar weakened against most major currencies.

For the six months ended June 30, 2025, net revenues in our semiconductor market increased by $126 million, or 18%, compared to the same period in the prior year. The increase was mainly due to an increase in sales of our semiconductor capital equipment at VSD related to strength in logic and foundry applications, upgrades to support existing NAND memory production and increased services revenues.

***Electronics and Packaging Market***

We are a foundational solutions provider for the electronics and packaging market. Our portfolio includes photonics components, laser drilling systems, electronics chemistries and plating equipment that are critical for the manufacturing of PCBs and package substrates, and critical to wafer level packaging ("WLP") applications. Similar to the semiconductor industry, the PCB, package substrate and WLP industries demand smaller features, greater density, and better performance. In addition, the electronics and packaging market also includes sales of our vacuum and photonics solutions for display manufacturing applications. We characterize our complementary offering of laser systems and chemistry solutions as Optimize the Interconnect®, to reflect the unique technology enablement we provide at the Interconnect level within PCBs, package substrates and WLPs.

For the three months ended June 30, 2025, net revenues in our electronics and packaging market increased by $13 million, or 5%, compared to the prior quarter primarily due to an increase in chemistry sales in the electronics market at MSD, mainly as a result of seasonally lower sales in the first quarter due to the Lunar New Year, partially offset by lower sales of PCB via drilling systems at PSD. Net revenues were also favorably impacted by foreign currency exchange rates.

For the six months ended June 30, 2025, net revenues in our electronics and packaging market increased by $82 million, or 19%, compared to the same period in the prior year. This increase was primarily due to higher sales of PCB via drilling systems at PSD and an increase in both chemistry and equipment sales at MSD.

***Specialty Industrial Market***

Our strategy in the specialty industrial market is to leverage our domain expertise and proprietary technologies across a broad array of applications in industrial, life and health sciences, and research and defense markets.

*Industrial*

Industrial encompasses a wide range of diverse applications, including chemistries for functional coatings, surface finishing and wear resistance in the automobile industry, vacuum solutions for synthetic diamond manufacturing and photonics for solar manufacturing. Other applications include vacuum and photonics solutions for light emitting diode and laser diode manufacturing.

*Life and Health Sciences*

Our products for life and health sciences are used in a diverse array of applications, including bioimaging, medical instrument sterilization, medical device manufacturing, analytical, diagnostic and surgical instrumentation, consumable medical supply manufacturing and pharmaceutical production.

*Research and Defense*

Our products for research and defense are sold to government, university and industrial laboratories for applications involving research and development in materials science, physical chemistry, photonics, optics and electronics materials. Our products are also sold for monitoring and defense applications, including surveillance, imaging and infrastructure protection.

For the three months ended June 30, 2025, net revenues in our specialty industrial market increased by $5 million, or 2%, compared to the prior quarter mainly due to higher chemistry sales in the automotive market at MSD as a result of seasonally lower sales in the first quarter due to the Lunar New Year, as well as higher revenue in our general industrial market at MSD. Net revenues in the specialty industrial market were also favorably impacted by foreign currency exchange rates.

For the six months ended June 30, 2025, net revenues in our specialty industrial market decreased by $53 million, or 9%, compared to the same period in the prior year. This decrease was mainly due to lower chemistry sales in the automotive market at MSD, lower revenues in the general industrial market at VSD and MSD as well as lower revenues across the

------

material processing, metrology and spectroscopy markets at PSD. These decreases were partially offset by higher revenue in the general industrial market at PSD.

***International Markets***

Starting in the second quarter of 2024, we changed our basis of reporting geographical net revenues from the location in which the sale originated to the shipped-to location of the end customer. Prior periods have been recast to reflect this change, which was made to better align with how management reviews geographical net revenues.

A significant portion of our net revenues is from sales to customers in international markets. For the six months ended June 30, 2025 and 2024, international net revenues accounted for approximately 81% and 76% respectively, of our total net revenues. A significant portion of our international net revenues was from customers in China, South Korea, Singapore, Taiwan and Japan. We expect international net revenues will continue to account for a significant percentage of total net revenues for the foreseeable future.

Long-lived assets located outside of the United States accounted for approximately 63% and 59% of our total long-lived assets as of June 30, 2025 and December 31, 2024, respectively. Long-lived assets include property, plant and equipment, net, right-of-use assets and certain other assets.

**Critical Accounting Policies and Estimates**

The preparation of our consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires management to make judgments, assumptions and estimates that affect the amounts reported. There have been no material changes in our critical accounting policies since December 31, 2024.

For further information about our critical accounting policies, please see the discussion of critical accounting policies in our Annual Report in the section captioned "Management's Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Estimates."

------

Research and development expenses increased by $6 million for the three months ended June 30, 2025 compared to the prior quarter, mainly due to an increase of $2 million in compensation-related costs, including fringe and variable compensation, and a $2 million unfavorable impact of foreign currency exchange rates. Research and development expenses increased $9 million for the six months ended June 30, 2025 compared to the same period in the prior year, primarily due to an increase of $10 million in compensation-related costs, including fringe and variable compensation.

Our research and development efforts are primarily focused on developing and improving our instruments, components, chemistry, subsystems, systems and process control solutions to improve process performance and productivity. We have thousands of products, and our research and development efforts primarily consist of a large number of projects related to these products, none of which is individually material. Projects typically have a duration of 3 to 36 months but may be extended for development of new products.

We continue to make product advancements designed to meet our customers' evolving needs. We have developed, and continue to develop, new products designed to address industry trends, such as the rising demand for more complex hardware architecture related to increasing investments in artificial intelligence, the shrinking of integrated circuit critical dimensions and technology inflections, and, in the flat panel display and solar markets, the transition to larger substrate sizes, which require more advanced processing and process control technology, the continuing drive toward more complex and accurate components and devices within the handset and tablet market, the transition to 5G for both devices and infrastructure, the growth in units and via counts in the high density interconnect PCB drilling market, and the transition from internal combustion to electric vehicles. In addition, we have developed, and continue to develop, products that support the migration to new classes of materials, ultra-thin layers, and 3D structures that are used in small geometry manufacturing. In our chemistry and equipment plating businesses, a majority of our research and development investment supports existing customers' product improvement needs and their short-term research and development goals, which enables us to pioneer new high-value solutions while limiting commercial risk. Research and development expenses consist primarily of salaries and related expenses for personnel engaged in research and development, fees paid to consultants, material costs for prototypes and other expenses related to the design, development, testing and enhancement of our products.

We believe that the continued investment in research and development and ongoing development of new products are essential to the expansion of our markets. We expect to continue to make significant investment in research and development activities. We are subject to risks from products not being developed in a timely manner, as well as from rapidly changing customer requirements and competitive threats from other companies and technologies. Our success depends on many of our products being designed into new generations of equipment for the semiconductor, electronics and packaging, and specialty industrial markets. We seek to develop products that are technologically advanced so that they are positioned to be chosen for use in each successive generation of semiconductor capital equipment and advanced markets applications. If our products are not chosen to be designed into our customers' products, our net revenues may be reduced during the lifespan of those products.

Our effective tax rates for the three months ended June 30, 2025 and March 31, 2025 were 13.6% and 12.3%, respectively. Our effective tax rates for the three months ended June 30, 2025 and March 31, 2025 were lower than the U.S. statutory tax rate, mainly due to the U.S. deduction for foreign derived intangible income ("FDII") and research and development credits, partially offset by foreign withholding taxes and a waiver of deductions related to U.S. base erosion payments.

Our effective tax rates for the six months ended June 30, 2025 and 2024 were 13.0% and 8.9%, respectively. Our effective tax rate for the six months ended June 30, 2025 was lower than the U.S. statutory tax rate mainly due to the U.S. deduction for FDII and research and development credits, partially offset by foreign withholding taxes and a waiver of deductions related to U.S. base erosion payments. Our effective tax rate for the six months ended June 30, 2024 was lower than the U.S. statutory tax rate mainly due to the U.S. deduction for FDII and research and development credits, partially offset by an increase in foreign withholding taxes and U.S. base erosion and anti-abuse tax.

Our future effective tax rate depends on various factors, including the impact of tax legislation, further interpretations and guidance from U.S. federal and state governments on the impact of proposed regulations issued by the Internal Revenue Service, as well as the geographic composition of our pre-tax income and changes in income tax reserves for unrecognized tax benefits. We monitor these factors and timely adjust our estimates of the effective tax rate accordingly. While we believe we have adequately provided for all tax positions, amounts asserted by taxing authorities could materially differ from our accrued positions as a result of uncertain and complex application of tax laws and regulations. Additionally, the recognition and measurement of certain tax benefits include estimates and judgment by management. Accordingly, we could record additional provisions or benefits for U.S. federal, state, and foreign tax matters in future periods as new information becomes available.

The Organisation for Economic Co-operation and Development ("OECD") and participating OECD member countries continue to work toward the enactment of a 15% global minimum corporate tax rate for large multinational enterprise groups, also known as "Pillar Two." Many of the participating countries have enacted legislation that became effective beginning in 2024, while other countries continue to work on defining the underlying rules and administrative procedures. Although the enacted and effective legislation in some countries was applicable to us as of January 1, 2024, and increased our effective

------

income tax rate, the increase did not have a material impact on our overall results of operations or cash flows. We will continue to monitor and evaluate the impact of the developing legislation.

On July 4, 2025, the One Big Beautiful Bill Act (the "OBBBA") was enacted into law. The OBBBA includes significant changes to the U.S. tax code, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework, and the restoration of favorable tax treatment for certain business provisions. The OBBBA has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. We are currently assessing the impact of the OBBBA on our consolidated financial statements.

**Liquidity and Capital Resources**

Cash and cash equivalents at June 30, 2025 and December 31, 2024 totaled $674 million and $714 million, respectively. The primary driver of our current and anticipated future cash flows is, and we expect will continue to be, cash generated from operations, consisting primarily of our net income, excluding non-cash charges and changes in operating assets and liabilities.

Our total cash and cash equivalents at June 30, 2025 consisted of $97 million held in the United States and $577 million held by our foreign subsidiaries. We believe that our current cash and investments position and available borrowing capacity, together with the cash anticipated to be generated from our operations, will be sufficient to satisfy our estimated working capital, planned capital expenditure requirements, payments of debt, and any future cash dividends declared by our Board of Directors or share repurchases through at least the next 12 months and the foreseeable future.

In periods when our sales are growing, higher sales to customers will result in increased trade receivables, and inventories will generally increase as we build products for future sales. This may result in lower cash generated from operations. Conversely, in periods when our sales are declining, our trade accounts receivable and inventory balances will generally decrease, resulting in increased cash from operations.

Net cash provided by operating activities was $306 million for the six months ended June 30, 2025 and resulted from net income of $114 million, which included non-cash charges of $175 million, mainly the result of $172 million in depreciation and amortization, partially offset by $80 million in deferred income taxes and a net decrease in working capital of $17 million. The net decrease in working capital was primarily due to increases in accrued compensation of $31 million and income taxes payable of $19 million as well as a decrease of other current and non-current assets of $11 million, partially offset by increases in trade accounts receivable of $10 million and inventories of $24 million as well as a decrease in other current and non-current liabilities of $14 million.

Net cash used in investing activities was $45 million for the six months ended June 30, 2025 primarily related to capital expenditures.

Net cash used in financing activities was $309 million for the six months ended June 30, 2025, consisting primarily of normal quarterly debt payments and a voluntary debt prepayment that together totaled $225 million, as well as the repurchase of our common stock of $45 million and dividend payments of $30 million.

On July 25, 2011, our Board of Directors approved a share repurchase program for the repurchase of up to an aggregate of $200 million of our outstanding common stock from time to time in open market purchases, privately negotiated transactions or through other appropriate means. The timing and quantity of any shares repurchased depends upon a variety of factors, including business conditions, stock market conditions and business development activities, including, but not limited to, merger and acquisition opportunities. These repurchases may be commenced, suspended or discontinued at any time without prior notice. Any repurchased shares are held by us as authorized but unissued shares.

During the six months ended June 30, 2025, we repurchased approximately 546,000 shares of our common stock for total consideration of $45 million. During the three months ended June 30, 2025 and six months ended June 30, 2024, we did not repurchase any shares of common stock. We have repurchased approximately 3.1 million shares of common stock for approximately $172 million pursuant to the program since its adoption.

Holders of our common stock are entitled to receive dividends when and if they are declared by our Board of Directors. During each of the first and second quarters of 2025 and 2024, our Board of Directors declared a cash dividend of $0.22 per share, totaling $30 million for each of the six months ended June 30, 2025 and 2024. On August 4, 2025, our Board of Directors declared a quarterly cash dividend of $0.22 per share to be paid on September 5, 2025 to stockholders of record as of August 25, 2025. Future dividend declarations, if any, as well as the record and payment dates for such dividends, are subject to the final determination of our Board of Directors.

<u>Credit Facilities</u>

In connection with the completion of the Atotech Acquisition, on August 17, 2022 (the "Effective Date") we entered into a credit agreement with JPMorgan Chase Bank, N.A., as administrative agent and collateral agent, Barclays Bank PLC, and the lenders from time to time party thereto, which we have amended several times since including, most recently, in January 2025 (as amended, the "Amended Credit Agreement"). As of June 30, 2025, the Amended Credit Agreement provided for (i) a senior secured term loan facility comprised of two tranches: a $2.4 billion loan (the "USD Tranche B") and a €591 million loan (the "Euro Tranche B" and together with the USD Tranche B, the "Term Loan Facility") and (ii) a senior secured revolving credit facility of $675 million (the "Revolving Facility" and, together with the Term Loan Facility, the "Credit Facilities"), with the commitments under each of the foregoing facilities subject to increase from time to time subject to certain conditions. In each of January 2025 and June 2025, we made voluntary prepayments of $100 million principal amount to the USD Tranche B loan.

As of June 30, 2025, borrowings under the Credit Facilities bore interest at a rate per annum equal to, at our option, any of the following, plus, in each case, an applicable margin: (a) with respect to the USD Tranche B and the Revolving Facility, (x) a base rate determined by reference to the highest of (1) the federal funds effective rate plus 0.50%, (2) the prime rate quoted in The Wall Street Journal, or (3) a forward-looking term rate based on the variable secured overnight financing rate ("Term SOFR") (plus an applicable credit spread adjustment) for an interest period of one month, plus 1.00%, and (y) a Term SOFR rate (plus an applicable credit spread adjustment) for the interest period relevant to such borrowing, subject to a rate floor of (I) with respect to the USD Tranche B, 0.50% and (II) with respect to the Revolving Facility, 0.0%; and (b) with respect to the Euro Tranche B, a Euro Interbank Offered Rate ("EURIBOR") rate determined by reference to the costs of funds for Euro deposits for the interest period relevant to such borrowing adjusted for certain additional costs, subject to a EURIBOR rate floor of 0.0%. As of June 30, 2025, the applicable margins for borrowings under the Credit Facilities were (i) under the USD Tranche B, 1.00% with respect to base rate borrowings and 2.00% with respect to Term SOFR borrowings, (ii) under the Euro Tranche B, 2.50% and (iii) under the Revolving Facility, 1.50% with respect to base rate borrowings and 2.50% with respect to Term SOFR borrowings.

In addition to paying interest on outstanding principal under the Credit Facilities, we are required to pay a commitment fee in respect of the unutilized commitments under the Revolving Facility. The commitment fee is subject to adjustment based on our first lien net leverage ratio as of the end of the preceding fiscal quarter. We must also pay customary letter of credit fees and agency fees. As of June 30, 2025, the commitment fee was 0.25% per annum.

As of June 30, 2025, the principal outstanding on the Term Loan Facility was $3.1 billion, and the weighted average interest rate was 5.9%. The Revolving Facility has a maturity date in August 2027 while the USD Tranche B and Euro Tranche B have a maturity date in August 2029. As of June 30, 2025, there were no borrowings under the Revolving Facility.

We are required to make scheduled quarterly principal payments equal to approximately $10 million with respect to the USD Tranche B and approximately €2 million with respect to the Euro Tranche B, in each case with the balance due thereunder on the seventh anniversary of the Effective Date. There is no scheduled amortization under the Revolving Facility. Any principal amount outstanding under the Revolving Facility is due and payable in full on the fifth anniversary of the Effective Date.

Under the Amended Credit Agreement, we are required to prepay outstanding term loans, subject to certain exceptions, with portions of our annual excess cash flow as well as with the net cash proceeds of certain of its asset sales, certain casualty and condemnation events and the incurrence or issuances of certain debt. If at any time the aggregate amount of outstanding loans, unreimbursed letter of credit drawings and undrawn letters of credit under the Revolving Facility exceeds the aggregate commitments under the Revolving Facility, we are required to repay outstanding loans and/or cash collateralize letters of credit, with no reduction of the commitment amount.

We may voluntarily prepay, and have voluntarily repaid, outstanding loans under the Credit Facilities from time to time, subject to certain conditions, without premium or penalty other than customary "breakage" costs with respect to Term SOFR or EURIBOR loans. Additionally, we may voluntarily reduce the unutilized portion of the commitment amount under the Revolving Facility.

On August 1, 2025, we made a voluntary prepayment of $100 million principal amount to the USD Tranche B loan.

All obligations under the Credit Facilities are guaranteed by certain of our wholly-owned domestic subsidiaries and are required to be guaranteed by certain of our future wholly-owned domestic subsidiaries, and are secured by substantially all of our assets and the assets of such subsidiaries, subject to certain exceptions and exclusions.

Under the Amended Credit Agreement, we have the ability to incur additional incremental debt facilities in an amount up to (x) the greater of (1) $1,011 million and (2) 75% of consolidated last 12 months earnings before interest, taxes, depreciation, and amortization, plus (y) an amount equal to the sum of all voluntary prepayments of term loans under the Term Loan Facility, plus (z) an additional unlimited amount subject to pro forma compliance with certain leverage ratio tests (based on the security and priority of such incremental debt).

------

The Amended Credit Agreement contains customary representations and warranties, covenants and provisions relating to events of default. As of June 30, 2025, we were in compliance with all covenants under the Amended Credit Agreement. The USD Tranche B and the Euro Tranche B are not subject to financial maintenance covenants.

<u>Convertible Notes</u>

On May 16, 2024, we completed a private offering of $1.4 billion aggregate principal amount of convertible senior notes due 2030 (the "Convertible Notes").

We used approximately $167 million of the net proceeds from the offering to pay the cost of the capped call transactions described below. We used the remaining net proceeds from the offering to repay approximately $1.2 billion in borrowings outstanding under the USD Tranche B, together with accrued interest, as well as for general corporate purposes.

*Indenture and the Convertible Notes*

On May 16, 2024, we entered into an indenture (the "Indenture") with respect to the Convertible Notes with U.S. Bank Trust Company, National Association, as trustee. Under the Indenture, the Convertible Notes are senior unsecured obligations of ours and bear interest at a coupon rate of 1.25% per annum, with interest payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2024. The Convertible Notes will mature on June 1, 2030, unless earlier converted, redeemed or repurchased in accordance with their terms.

Subject to certain conditions, on or after June 5, 2027, we may redeem for cash all or any portion of the Convertible Notes at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the trading day immediately preceding the date the notice of redemption is sent.

The conversion rate for the Convertible Notes is initially 6.4799 shares of our common stock per one thousand dollars principal amount of the Convertible Notes, which is equivalent to an initial conversion price of approximately $154.32 per share. The conversion rate is subject to adjustment upon the occurrence of certain events.

Upon conversion, we will pay cash up to the aggregate principal amount of the Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock, at our election, in respect of the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted. Prior to March 1, 2030, noteholders may convert all or any portion of their Convertible Notes only upon the occurrence of certain events and during certain periods, and thereafter, at any time until the second scheduled trading day immediately preceding the maturity date.

If we undergo a fundamental change (as defined in the Indenture) prior to the maturity date of the Convertible Notes, holders may require us to repurchase for cash all or any portion of their Convertible Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The Indenture contains customary terms and covenants, including that upon certain events of default that are occurring and continuing, either the trustee or the holders of at least 25% in aggregate principal amount of the outstanding Convertible Notes may declare 100% of the principal of, and accrued and unpaid interest, if any, on, all the Convertible Notes to be due and payable.

As of June 30, 2025, the Convertible Notes were classified as a long-term liability, net of issuances costs, on the condensed consolidated balance sheet. The Convertible Notes were issued at par and costs associated with the issuance of the Convertible Notes are amortized to interest expense over the contractual term of the Convertible Notes. As of June 30, 2025, the effective interest rate of the Convertible Notes was 1.56%.

------

*Capped Call Transactions*

On May 13, 2024, in connection with the pricing of the Convertible Notes, and on May 14, 2024, in connection with the exercise in full by the initial purchasers of their option to purchase additional Convertible Notes, we entered into privately negotiated capped call transactions with certain of the initial purchasers of the Convertible Notes or their respective affiliates and other financial institutions. The capped call transactions are expected generally to reduce the potential dilution to our common stock upon conversion of any Convertible Notes and/or offset any cash payments that we are required to make in excess of the principal amount of any converted Convertible Notes, as the case may be, with such reduction and/or offset subject to a cap initially equal to $237.42 per share, which represents a premium of 100% over the last reported sale price of $118.71 per share of our common stock on The Nasdaq Global Select Market on May 13, 2024, and is subject to customary adjustments under the terms of the capped call transactions.

<u>Lines of Credit and Borrowing Arrangements</u> 

Certain of our Japanese subsidiaries have lines of credit and a financing facility with various financial institutions, many of which generally expire and are renewed at three-month intervals with the remaining having no expiration date. The lines of credit and financing facility provided for aggregate borrowings as of June 30, 2025 and December 31, 2024 of up to an equivalent of $14 million and $19 million, respectively. There were no borrowings outstanding under these arrangements at June 30, 2025 and December 31, 2024.

<u>Derivatives</u> 

We enter into derivative instruments for risk management purposes only, including derivatives designated as hedging instruments and those utilized as economic hedges. We operate internationally, and in the normal course of business, are exposed to fluctuations in interest rates and foreign exchange rates. These fluctuations can increase the costs of financing, investing and operating the business. We have used derivative instruments, such as foreign exchange forward contracts and net investment hedges, to manage certain foreign currency exposure, and interest rate swaps and caps to manage certain interest rate exposure. We do not enter into derivative instruments for trading or speculative purposes.

By nature, all financial instruments involve market and credit risks. We enter into derivative instruments with major investment grade financial institutions and no collateral is required. We have policies to monitor the credit risk of these counterparties. While there can be no assurance, we do not anticipate any material non-performance by any of these counterparties.

<u>Interest Rate Swap</u>

We have various interest rate swap agreements described further in Note 5 of the condensed consolidated financial statements. These interest rate swap agreements exchange the variable Term SOFR rate to a fixed rate in order to manage the exposure to interest rate fluctuations associated with the variable Term SOFR rate paid on the outstanding balance of the Term Loan Facility.

**Contractual Obligations**

There have been no changes outside the ordinary course of business to our contractual obligations as disclosed in our Annual Report.

**Recent Accounting Pronouncements**

<u>Income Taxes (Topic 740): Improvements to Income Tax Disclosures</u>

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"), which focuses on the rate reconciliation and income taxes paid. ASU 2023-09 requires a public business entity ("PBE") to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. For PBEs, the new standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. An entity may apply the amendments prospectively by providing the revised disclosures for the period ending December 31, 2025 and continuing to provide the pre-ASU disclosures for the prior periods or may apply the amendments retrospectively by

------

providing the revised disclosures for all periods presented. We are currently evaluating the impact on the consolidated financial statement disclosures; however, adoption will not impact our consolidated balance sheets, cash flows or income statements.

<u>Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses</u>

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses ("ASU 2024-03"), which requires public companies to disclose, in interim and annual reporting periods, additional information about certain income statement expense line items in the notes to financial statements. The amendments in ASU 2024-03 are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impact on the consolidated financial statement disclosures; however, adoption will not impact our consolidated balance sheets, cash flows or income statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Information concerning market risk is contained in the section entitled "Quantitative and Qualitative Disclosures About Market Risk" contained in our Annual Report. As of June 30, 2025, there were no material changes in our exposure to market risk from December 31, 2024.

ITEM 4. CONTROLS AND PROCEDURES.

**Evaluation of Disclosure Controls and Procedures**

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2025. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the U.S. Securities and Exchange Commission's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer's management, including its principal executive and principal financial officers, or persons performing similar functions as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2025, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in U.S. Securities and Exchange Commission's rules and forms and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

**Changes in Internal Control over Financial Reporting**

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1A. RISK FACTORS.

ITEM 5. OTHER INFORMATION.

For the three months ended June 30, 2025, none of our directors or officers (as defined in Rule 16a-1(f) under the Exchange Act) adopted or terminated a trading arrangement for the sale or purchase of Company securities that is either (1) a contract, instruction or written plan intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or (2) a "non-Rule 10b5-1 trading arrangement" (as defined in Item 408(c) of Regulation S-K).
