Rhea-AI Filing Summary

Entegris (ENTG) authorized a share repurchase program for up to $500 million of outstanding common stock and outlined an updated long-term financial model. The program has no expiration date, does not require Entegris to repurchase a particular amount, and may be suspended or discontinued at any time. Repurchases may be made through open-market purchases, privately negotiated transactions, accelerated share repurchase arrangements or Rule 10b5-1 trading plans; management will determine amounts and timing based on market conditions and other factors. Entegris expects to increase its quarterly cash dividend by 10% beginning in the first quarter of 2027, subject to the Board's discretion and approval of the declaration, amount and timing.

The long-term targets are approximately 15% revenue CAGR, 55% adjusted gross margin, 35% adjusted operating margin and 30% adjusted earnings-per-share CAGR. Entegris's capital allocation framework calls for returning approximately 50% of excess cash to shareholders. The adjusted targets are non-GAAP measures; the company says it cannot reconcile these forward-looking measures because excluded items cannot be reasonably predicted and could be material.

compound annual growth rate financial
"compound annual growth rate (CAGR) for revenue"
The compound annual growth rate (CAGR) shows how much an investment or value has grown, on average, each year over a specific period. It considers the effect of growth that compounds or builds upon itself, similar to how interest accumulates in a savings account. Investors use CAGR to compare different investments’ long-term performance and to understand how steady or consistent their growth has been over time.
adjusted gross margin financial
"adjusted gross margin of approximately 55%"
Adjusted gross margin is a measure of how much profit a company makes from its sales after accounting for certain expenses or one-time costs, but before deducting other operating expenses. It helps investors see the company's core profitability more clearly by removing factors that might distort the usual profit picture, similar to a runner measuring their speed without considering obstacles or weather. This metric provides a clearer view of the company's ongoing financial health.
accelerated share repurchase arrangements financial
"accelerated share repurchase arrangements or Rule 10b5-1 trading plans"
A contractual program in which a company hires an investment bank to buy back a large block of its own shares immediately, while the bank acquires those shares from the market or borrows them and later settles the transaction with the company based on the actual market price over a predetermined period. The arrangement gives the company an immediate reduction in shares outstanding and transfers the risk of short‑term price movement to the bank; final settlement typically adjusts the exact number of shares delivered or requires a cash payment or receipt tied to the average share price during the settlement window.
non-GAAP financial measures financial
"measures that are not presented in accordance with U.S. generally accepted accounting principles"
Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.

NEWS RELEASE

ENTEGRIS DETAILS GROWTH STRATEGY AND LONG-TERM FINANCIAL MODEL AT 2026 CAPITAL MARKETS DAY


•
Entegris updates its long-term revenue CAGR target to ~15%, driven by customers’ increasing materials intensity and contamination control requirements

•
Disciplined execution and capital efficiency expected to support significantly higher profitability and cash flow

•
Board authorizes $500 million share repurchase program

BILLERICA, Mass., November 9, 2026 - Entegris, Inc. (Nasdaq: ENTG), a leading supplier of critical advanced materials and process solutions for the semiconductor and other high-technology industries, today outlined its long-term growth strategy and financial model at its 2026 Capital Markets Day.

Dave Reeder, President and Chief Executive Officer of Entegris, said, “AI is driving a new era of semiconductor innovation, accelerating technology transitions and increasing the complexity of device architectures. As the requirements for materials and purity continue to rise, Entegris is more critical than ever to enabling the industry’s most advanced technologies. Our technology leadership, broad portfolio and strong customer partnerships, position us to capture these opportunities, while we continue to accelerate innovation, productivity and execution across the company. We expect strong revenue and earnings growth, together with greater capital efficiency, to drive increased cash flow, enabling us to invest in growth while returning approximately 50% of excess cash to shareholders.”

At Capital Markets Day, Entegris introduced an updated long-term financial model targeting a compound annual growth rate (“CAGR”) for revenue of approximately 15%, adjusted gross margin of approximately 55%, adjusted operating margin of approximately 35%, and adjusted earnings per share CAGR of approximately 30%. The company expects revenue growth, significant margin expansion and greater capital efficiency will accelerate cash flow generation.

With significant progress made in reducing its net leverage ratio, Entegris also outlined its long-term capital allocation framework, focused on investing in organic growth and innovation, executing a disciplined approach to strategic M&A and returning approximately 50% of excess cash to shareholders.

In support of this capital allocation framework, Entegris announced that its Board of Directors has authorized a $500 million share repurchase program and that the company expects to raise its quarterly cash dividend by 10% starting in the first quarter of 2027, subject to declaration by the Board. Share repurchases may be made from time to time through open market purchases, privately negotiated transactions, accelerated share repurchase arrangements or Rule 10b5-1 trading plans, in amounts and at times determined by management based on market conditions and other factors. The repurchase program does not obligate the company to acquire any particular amount of its common stock and may be suspended or discontinued at any time.

A webcast replay of the Capital Markets Day event and the accompanying presentation materials will be available on the Investor Relations section of Entegris’ website at investor.entegris.com.

USE OF NON-GAAP FINANCIAL MEASURES

This news release contains references to “Adjusted Operating Margin,” “Adjusted Gross Margin,” “Diluted Non-GAAP Earnings per Common Share” and other measures that are not presented in accordance with U.S. generally accepted accounting principles (“GAAP”).  Management uses these non-GAAP financial measures to evaluate Entegris, Inc.’s (the “Company”) operating and financial performance and for planning purposes, and believes they provide investors with useful supplemental information and facilitate period-to-period comparisons by excluding items that management does not consider indicative of the Company’s ongoing operating performance.  The non-GAAP financial measures should not be considered in isolation or as a substitute for GAAP financial measures but should instead be read in conjunction with the GAAP financial measures. Non-GAAP financial measures have limitations: they do not reflect all of the amounts associated with the Company’s results as determined in accordance with GAAP, the excluded items may recur and may have a material impact on the Company’s reported results, and other companies may calculate similarly titled measures differently, which may limit their usefulness as comparative measures.  Further information with respect to and reconciliations of such historical measures, and of the estimated 2026 non-GAAP financial measures presented, to the most directly comparable GAAP measure can be found on our website. The Company does not provide a reconciliation of the forward-looking non-GAAP financial measures reflected in its long-term financial targets to the most directly comparable GAAP measures because certain items excluded from these non-GAAP measures, such as restructuring, acquisition-related and impairment charges, cannot be reasonably predicted or estimated without unreasonable efforts due to their inherent uncertainty. These items could be material, individually or in the aggregate, to the Company’s future GAAP results.
