ENTEGRIS REPORTS RESULTS FOR FIRST QUARTER OF 2024

•Net sales of $771 million, decreased 16% from prior year and 5% sequentially

•Adjusted net sales decreased 5% from prior year and 4% sequentially (excluding the impact of divestitures)

•GAAP diluted EPS of $0.30

•Non-GAAP diluted EPS of $0.68

BILLERICA, Mass., May 1, 2024 - Entegris, Inc. (NASDAQ: ENTG), today reported its financial results for the Company’s first quarter ended March 30, 2024.

Bertrand Loy, Entegris’ president and chief executive officer, said: “We are pleased with our positive start to the year. Sales of $771 million were at the high end of our guidance. Adjusted EBITDA and non-GAAP EPS were above our guidance, even while we increased critical R&D investments. During the quarter, we sold the Pipeline and Industrial Materials (PIM) business, completing all our planned divestitures of non-core assets. Using the PIM sale proceeds and cash on hand, we paid down over $400 million of debt during the quarter.”

Mr. Loy added: "For 2024, our view of the semiconductor industry has not changed. We believe that the market is healthier, with normalizing inventories of semiconductors and a more stable demand environment. We continue to expect a gradual market recovery throughout the year. In addition, we expect Entegris will continue to outgrow the market and show leverage in our model.”

“We remain very optimistic about the long-term growth prospects for the semiconductor industry and Entegris,” he said. “The industry is entering a period of unprecedented technology change and device complexity. Our core competencies in materials science and materials purity, coupled with our unique ability to co-optimize solutions that shorten time to yield, have become increasingly critical for our customers. All of this means the market is moving toward Entegris, translating into rapidly expanding content per wafer and strong outperformance for us for years to come.”

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 divestitures), 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.
