ENTEGRIS REPORTS RESULTS FOR THIRD QUARTER OF 2026

•Net sales of $1,006 million.

•GAAP diluted EPS of $1.03.

•Non-GAAP diluted EPS of $1.23.

BILLERICA, Mass., October 29, 2026 - Entegris, Inc. (NASDAQ: ENTG), today reported its financial results for the Company’s third quarter ended September 26, 2026.

Dave Reeder, Entegris’ President and Chief Executive Officer, said: “Entegris is executing well against an attractive long-term opportunity, driven by increasing semiconductor complexity, rising materials intensity, and investment in leading-edge technologies. Our ability to deliver the performance, quality, and reliability our customers require is helping us expand plans of record and secure new design wins, driving strong revenue growth across our unit and capex businesses. That growth, combined with disciplined execution, drove another strong quarter, highlighted by record revenue, continued margin expansion and strong earnings growth, all of which exceeded our guidance range. We also delivered record cash flow, enabling us to accelerate debt repayment and further strengthen our balance sheet. We look forward to discussing the significant opportunities ahead for Entegris and our long-term strategy in more detail at our Capital Markets Day on November 9, 2026.”

Non-GAAP Information

The Company’s condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States (GAAP). Adjusted Net Sales, Adjusted EBITDA, Adjusted Gross Profit, Adjusted Segment Profit, Adjusted Operating Income, non-GAAP Net Income, non-GAAP Adjusted Operating Margin and diluted non-GAAP Earnings Per Common Share, together with related measures thereof, are considered “non-GAAP financial measures” under the rules and regulations of the Securities and Exchange Commission. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. The Company provides supplemental non-GAAP financial measures to better understand and manage its business and believes these measures provide investors and analysts additional and meaningful information for the assessment of the Company’s ongoing results. Management also uses these non-GAAP measures to assist in the evaluation of the performance of its business segments and to make operating decisions. Management believes that the Company’s non-GAAP measures help indicate the Company’s baseline performance before certain gains, losses or other charges that may not be indicative of the Company’s business or future outlook, and that non-GAAP measures offer a more consistent view of business performance. The Company believes the non-GAAP measures aid investors’ overall understanding of the Company’s results by providing a higher degree of transparency for such items and providing a level of disclosure that will help investors generally understand how management plans, measures and evaluates the Company’s business performance. Management believes that the inclusion of non-GAAP measures provides greater consistency in its financial reporting and facilitates investors’ understanding of the Company’s historical operating trends by providing an additional basis for comparisons to prior periods. The reconciliations of GAAP net sales to Adjusted Net Sales (excluding divestiture), GAAP gross profit to Adjusted Gross Profit, GAAP segment profit to Adjusted Operating Income, GAAP net income to Adjusted Operating Income and Adjusted EBITDA, GAAP net income and diluted earnings per common share to non-GAAP Net Income and diluted non-GAAP Earnings Per Common Share and GAAP outlook to non-GAAP outlook are included elsewhere in this release.

(1) In the three months ended September 26, 2026, the Company received $8.3 million of refunds of International Emergency Economic Powers Act (IEEPA) tariffs that were recognized in cost of goods sold as incurred from April 2025 through February 2026 and were not excluded from the Company's non-GAAP results in those periods. The Company excluded the IEEPA tariff refunds from non-GAAP results because they represent a discrete, non-recurring, out-of-period recovery arising from a legal and regulatory development rather than ongoing operating performance.

(2) Restructuring charges resulting from discrete cost saving initiatives inclusive of employee termination benefit and asset impairment charges, primarily related to (i) an internal reorganization, combining two complementary divisions into one and realigning our customer-facing organization, (ii) workforce reductions and (iii) the planned wind-down of the Company’s Life Sciences Fluid Management business.

15 ENTEGRIS THIRD QUARTER 2026 EARNINGS SUMMARY 1.In the three months ended September 26, 2026, the Company received $8.3 million of refunds of International Emergency Economic Powers Act (IEEPA) tariffs that were recognized in cost of goods sold as incurred from April 2025 through February 2026 and were not excluded from the Company's non-GAAP results in those periods. The Company excluded the refunds from non-GAAP results because they represent a discrete, non-recurring, out-of-period recovery arising from a legal and regulatory development rather than ongoing operating performance. 2.Restructuring charges resulting from discrete cost saving initiatives inclusive of employee termination benefit, contract termination costs and asset impairment charges, primarily related to (i) an internal reorganization, combining two complementary divisions into one and realigning our customer facing organization, (ii) workforce reductions and (iii) the planned wind-down of the Company’s Life Sciences Fluid Management business. 3.Non-recurring net loss from the sale of a small, industrial specialty chemicals business. 4.
