These unaudited Condensed Consolidated Financial Statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”), and, therefore, omit certain information and footnote disclosures necessary to present the unaudited Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Consolidated Financial Statements and notes thereto included in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the SEC on February 27, 2026. The results of operations 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 or any other future period, and we make no representations related thereto.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition and deferred revenues, useful lives of intangible assets and property, plant and equipment, goodwill, income taxes, contingent liabilities, the fair values of financial instruments, stock-based compensation and the valuation of investments in privately held companies among others. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. In connection with the 2025 Restructuring activities discussed in Note 14 “Restructuring and Other Charges,” we committed to a plan to dispose of, other than by sale, specifically identified manufacturing assets prior to the end of their estimated useful lives during the third quarter of 2025. Accordingly, we have revised the estimated useful lives of these assets to reflect our use through the disposal date. For the three months ended March 31, 2026, we recorded $15.6 million of accelerated depreciation expense related to these assets. The increase in depreciation expense negatively impacted Net income, net of tax, by $11.8 million or $0.17 per basic share and $0.16 per diluted share. We have materially completed the disposition of these assets as of March 31, 2026.

The amendments in this ASU also require the application of ASC 360-10 disclosure requirements for all capitalized internal-use software costs, regardless of how those costs are presented in the financial statements. The provisions of ASU 2025-06 are effective for all entities for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years. Early adoption is permitted. The Company is evaluating the effect of this pronouncement on its annual consolidated financial statements. On November 4, 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures.” The amendments in this ASU require a public entity to disclose, in the notes to the financial statements, specified information about certain costs and expenses, including the amounts of inventory purchases, employee compensation, depreciation and intangible asset amortization. For public business entities, the provisions of ASU 2024-03 are effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. There will be no impact to our consolidated balance sheets or statements of operations; however, the Company is evaluating the effect of this pronouncement on our consolidated financial statement disclosures.

Actual results could differ materially from those estimates. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition and deferred revenues, useful lives of intangible assets and property, plant and equipment, goodwill, income taxes, contingent liabilities, the fair values of financial instruments, stock-based compensation and the valuation of investments in privately held companies among others. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
