&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** *Fourth-quarter revenue (as reported) of $946 million, increased 49% from prior year*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** *Fourth-quarter revenue (proforma), increased 1%*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Full-year 2022 revenue (as reported), increased 43% from prior year*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** *Full-year 2022 revenue (proforma), increased 13%*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** *Fourth-quarter GAAP diluted EPS of $0.38*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** *Fourth-quarter non-GAAP diluted EPS of $0.83*

**BILLERICA, Mass., February 14, 2023 -** <u>Entegris</u>, Inc. (NASDAQ: ENTG), today reported its financial results for the Company's fourth quarter ended December 31, 2022. Fourth-quarter sales were $946.1 million, an increase of 49% from the same quarter last year. Fourth-quarter GAAP net income was $57.4 million, or $0.38 earnings per diluted share, which included $53.5 million of amortization of intangible assets, $18.6 million of integration costs, $0.3 million of deal and transaction costs, $3.6 million contractual and non-cash integration costs. Non-GAAP net income was $124.5 million for the fourth quarter and non-GAAP earnings per diluted share was $0.83. All the results presented herein (unless noted) are shown on a "as reported" basis and not on a "proforma" basis, and as a result do not include CMC Materials' results in prior periods. Results in the second half of 2022 include CMC Materials.

Bertrand Loy, Entegris' president and chief executive officer, said: "Our solid fourth quarter results capped off a strong year for Entegris. Sales (proforma) grew 13 percent in 2022, several points higher than estimated industry growth. This above-market growth was driven in large part by our strong position at the leading-edge technology nodes."

Mr. Loy added: "2023 is shaping up to be an uncertain year for the semiconductor industry. Given this backdrop, we will take the necessary steps to manage costs, prioritize cash flow and debt paydown, while making the R&D investments that are critical for our future growth. Our differentiated unit-driven model and experienced team will be key as we navigate this near-term environment."

Mr. Loy added: "Looking further ahead, the positive long-term secular growth drivers of the semiconductor industry are intact. At the same time, as device architectures become more complex, Entegris breadth of capabilities in material sciences and contamination control enable us to offer unique solutions to help our customers improve performance and shorten their time to yield. We believe these trends and our increasingly mission critical solutions will translate into rapidly expanding content per wafer for Entegris."

**First-Quarter Outlook**

For the first quarter ending April 1, 2023, the Company expects sales of $880 million to $910 million, net income of $8 million to $16 million and diluted earnings per common share between $0.05 and $0.10. On a non-GAAP basis, the Company expects diluted earnings per common share to range from $0.50 to $0.55, reflecting net income on a non-GAAP basis in the range of $75 million to $83 million. The company also expects EBITDA of approximately 25% to 26% of sales, for the first quarter of 2023. First quarter non-GAAP guidance includes an approximately $20 million increase (or $0.11 of non-GAAP EPS) in non-cash equity compensation expense compared to the fourth quarter of 2022, resulting from the alignment of CMC Material's and Entegris' equity benefit plans. The increase is the result of changes in award features and the related accounting, not a significant increase in overall equity grants. In addition, a higher expected tax rate in the first quarter of 2023, is expected to result in an approximately $0.05 impact to non-GAAP EPS, compared to the fourth quarter of 2022.

**Segment Results**

In connection with the completion of the CMC Materials acquisition, the company now operates in four segments (which include the new APS division):

**Specialty Chemicals and Engineered Materials (SCEM):** SCEM provides advanced materials enabling complex chip designs and improved device electrical performance; including high-performance and high-purity process chemistries, gases and materials and safe and efficient delivery systems to support semiconductor and other advanced manufacturing processes.

**Microcontamination Control (MC):** MC offers advanced filtration solutions that improve customers' yield, device reliability and cost; by filtering and purifying critical liquid chemistries and gases used in semiconductor manufacturing processes and other high-technology industries.

**Advanced Materials Handling (AMH):** AMH develops solutions that improve customers' yields by protecting critical materials during manufacturing, transportation, and storage; including products that monitor, protect, transport and deliver critical liquid chemistries, wafers, and other substrates for a broad set of applications in the semiconductor, life sciences and other high-technology industries.

**Advanced Planarization Solutions (APS):** APS develops an end-to-end chemical mechanical planarization (CMP) solution and applications expertise delivered through advanced materials and high purity chemicals; including CMP slurries, pads, formulated cleans and other electronic chemicals used in the semiconductor manufacturing processes.

**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 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.
