Entegris, Inc. (ENTG) Up 9.9% — Should I Move From Watching to Buying?
Entegris, Inc. (ENTG) is surging on Monday, last trading at $140.70 on the NASDAQ — a $12.72 gain from the prior close of $127.98. The rally recovers a meaningful slice of ground the stock has given up since peaking at $186.94 on June 22, 2026. Even after today's jump, ENTG trades roughly 24.7% below that 52-week high. For investors who believe the AI-driven materials cycle is still in its early innings, that gap is room to run.
Volume so far stands at 444,375 shares against a 90-day average of roughly 2.64 million, with the regular session still open. The bulk of the day's turnover is still ahead.
Why Entegris, Inc. Price is Moving Higher
The broad backdrop is a powerful semiconductor rebound. The Philadelphia Semiconductor Index was up 4.78% at an intraday check, and chip names are rallying even as NVIDIA Corporation (NVDA) has slipped 3.87%. Equipment and infrastructure names are leading the charge. Applied Materials, Inc. (AMAT) is up 10.59% and Broadcom Inc. (AVGO) has gained 9.04%, which places ENTG among the session's front-runners. Entegris is rising roughly twice as fast as the sector index, though, and that points to company-specific enthusiasm layered on top of the tailwind.
That enthusiasm has been building all month around Entegris's AI materials strategy. On November 3, the company said it had acquired Advanced Abrasives and planned a Taiwan manufacturing line for silicon-carbide polishing products. The same day, it announced a partnership with Element Six on diamond-based thermal materials for AI chip packaging. Two days later, on November 5, Entegris expanded its collaboration with Kioxia on materials for future 3D flash memory. All of that converges on today, when Entegris is hosting its Capital Markets Day with its thermal-management strategy on the agenda. That puts the company's newest AI-packaging initiatives in front of investors on the same session the sector is ripping higher.
The fundamentals give the story weight. Entegris reported Q3 results on October 29, and adjusted EPS came in at $1.23, well ahead of the $1.02 estimate. Revenue reached $1.006 billion against a $923.81 million consensus, a 25% year-over-year increase that pushed quarterly sales past the $1 billion mark. Adjusted EBITDA margin expanded to 30.2% from 27.3%, so the growth is coming with improving profitability. Management also guided Q4 sales to $1.025 billion to $1.055 billion and adjusted EPS to $1.32 to $1.40, which signals that the momentum is expected to carry through year-end.
What is the Entegris, Inc. Rating - Should I Buy?
Weiss Ratings assigns ENTG a B- rating. Current recommendation is Buy. The rating reflects a company with strong growth, a sturdy balance sheet and a solid record of rewarding shareholders. Its share price swings are the main reason the rating is held below the B tier.
The core of the case is strong. The Excellent rating on the Growth Index is backed by 24.61% revenue growth, an impressive pace for a materials supplier whose sales track wafer starts and fab utilization rather than end-product hype. The Excellent Solvency Index rating shows that Entegris has the financial footing to fund acquisitions like Advanced Abrasives and new capacity in Taiwan without stretching itself. The Excellent rating on the Total Return Index reflects how well the stock has rewarded holders over the measurement period, even accounting for the pullback from June's high. The Efficiency Index is rated Good rather than Excellent. A 9.55% ROE and an 11.14% profit margin are respectable, but they still trail the 30.2% adjusted EBITDA margin the business generated last quarter. That gap suggests reported returns have room to catch up as integration and amortization costs roll off.
Where the picture becomes more nuanced is volatility and income. The Weak Volatility Index rating is easy to see in today's price action. A roughly 10% single-session jump on a sector-wide chip rebound comes only months after a slide of nearly 25% from the $186.94 peak. Holders need a tolerance for sharp swings in both directions, especially with the stock priced at a forward P/E of 55.70 that leaves little cushion if growth stumbles. The Weak Dividend Index rating follows from a 0.28% yield. Entegris is a growth vehicle that reinvests heavily in capacity and technology, and income investors should look elsewhere.
Within the Information Technology sector, Entegris is on par with Micron Technology, Inc. (MU, B-) and Applied Materials, Inc. (AMAT, B-), two names also benefiting from the AI build-out. It sits a notch below NVIDIA Corporation (NVDA, B), Broadcom Inc. (AVGO, B) and Texas Instruments Incorporated (TXN, B). That company is a strong one for a specialty materials supplier with a market cap of $21.83 billion.
About Entegris, Inc.
Entegris, Inc. (ENTG) is an Information Technology company headquartered in Billerica, Massachusetts. The company supplies the specialty materials and high-purity process solutions that chipmakers rely on to manufacture advanced semiconductors. Its portfolio spans chemical mechanical planarization slurries, pads and post-CMP cleaners, along with specialty chemicals, deposition precursors and selective etch materials. Those products are used at nearly every critical step of wafer processing.
The second pillar of the business centers on contamination control and purity. Entegris makes liquid and gas filtration and purification systems that strip particles and impurities out of process fluids at the parts-per-trillion level. It also makes fluid-handling components and wafer-handling products such as front-opening unified pods and reticle pods, which protect wafers and photomasks as they move through the fab. As chip geometries shrink and 3D architectures like advanced flash memory and stacked logic multiply process steps, demand rises for both the volume and the purity of these materials.
Entegris's competitive edge comes from deep integration with leading chipmakers, which often qualify its materials into specific process recipes. Once qualified, those products are costly and time-consuming to replace, which makes them sticky. The company is pushing that position into AI packaging and power semiconductors. Its silicon-carbide polishing products, the Advanced Abrasives acquisition, and diamond-based thermal materials developed with Element Six all target the heat and precision challenges of next-generation AI chips. The expanded Kioxia collaboration on future 3D flash memory adds another long-term relationship in memory.
Investor Outlook
Entegris, Inc. (ENTG) carries a Weiss Rating of B- (Buy), and today's rally pairs a sector rebound with a company actively positioning itself as a materials leader for AI chip packaging. Investors should watch for takeaways from the November 9 Capital Markets Day on thermal-management revenue opportunities. They should also watch whether Q4 results land within the $1.025 billion to $1.055 billion sales range and the $1.32 to $1.40 adjusted EPS range management has guided.
