•Fourth-quarter GAAP diluted EPS of $0.25

BILLERICA, Mass., February 13, 2024 - Entegris, Inc. (NASDAQ: ENTG), today reported its financial results for the Company’s fourth quarter ended December 31, 2023. Fourth-quarter sales were $812.3 million, a decrease of 14% from the same quarter last year. Fourth-quarter GAAP net income was $38.0 million, or $0.25 income per diluted share, which included $30.0 million of gain on termination of the Alliance Agreement with MacDermid Enthone, $10.4 million of goodwill impairment, $30.5 million of impairment of long-lived assets, $51.0 million of amortization of intangible assets, $7.8 million of integration costs related to the acquisition of CMC Materials and $14.6 million of other net costs. Non-GAAP net income was $97.9 million for the fourth quarter and non-GAAP earnings per diluted share was $0.65.
Bertrand Loy, Entegris’ president and chief executive officer, said: “Our unit driven model has displayed strong resilience during the current industry downturn. We closed 2023 with fourth quarter sales and non-GAAP EPS results above our guidance. For the year, we outperformed the market by 6 points, driven in large part by our strong position at the leading-edge technology nodes. In addition, we divested three non-core businesses and used the proceeds and free cash flow to pay off $1.3 billion of debt. We also continued to make significant R&D and capacity investments, which are vital for our long-term growth.”
Mr. Loy added: “As we enter 2024, inventories of semiconductors have largely normalized, end demand has stabilized in most segments, and we expect a gradual industry recovery to occur throughout the year. In addition, we expect Entegris will continue to outgrow the market and show leverage in our model.”
Mr. Loy concluded: “We remain as optimistic as ever about the long-term growth prospects for the semiconductor industry. The industry is entering a period of unprecedented technology change and device complexity. This means the market is moving toward Entegris. Our core value proposition in materials science, materials purity, and end-to-end solutions has become increasingly enabling and critical for our customers. This will translate into rapidly expanding Entegris content per wafer, strong outperformance and earnings growth 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). Proforma 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 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.
