Exploring Entegris, Inc. (ENTG) Investor Profile: Who’s Buying and Why?

You've seen Entegris, Inc. (ENTG) stock trading around the $78.28 mark in November 2025, but do you defintely know which major players are building or shedding positions in this critical semiconductor materials supplier? The answer is institutional money, which controls a staggering $13.81 billion worth of shares-that's 176,422,252 total shares as of the September 30, 2025 filings, representing almost all of the float. While firms like BlackRock, Inc. and The Vanguard Group, Inc. remain top holders, the near-term trading tells a more nuanced story: 290 institutions increased their positions, nearly matching the 293 that sold down, showing a real tug-of-war over the stock as the company navigates its Q4 2025 revenue guidance of $790.0 million to $830.0 million. Who is winning that battle, and what does it mean for the consensus 2025 EPS forecast of $2.77? You need to look past the headline price to understand the conviction behind the trades.

Who Invests in Entegris, Inc. (ENTG) and Why?

The short answer is that Entegris, Inc. (ENTG) is overwhelmingly an institutional favorite, with the investment thesis centered on its critical role in the long-term, high-growth semiconductor industry. You're looking at a stock where nearly all the float is held by major asset managers, not individual investors.

The core of the shareholder base is institutional money, which comprises approximately 99.28% of the company's stock, based on recent 2025 filings. This means big players like pension funds and mutual funds are the ones setting the price action. Retail investors, in contrast, hold a tiny fraction, around 0.22%. It's a stock for the professional portfolio, defintely not one driven by social media chatter.

Key Investor Types and Their Weight

When we peel back the institutional layer, we see a clear hierarchy. The top holders are the giants of passive and active management, which signals a belief in the company's foundational, long-term value. Here's the quick math on who owns the most shares, with all amounts based on 2025 fiscal year data:

• BlackRock, Inc.: Held over 17.05 million shares, valued at approximately $1.24 billion as of September 29, 2025.
• The Vanguard Group, Inc.: Held over 16.01 million shares, valued at roughly $1.16 billion as of September 29, 2025.
• T. Rowe Price Group, Inc.: Held over 16.13 million shares, valued at about $1.17 billion as of June 29, 2025.

These passive giants, like BlackRock, Inc. and The Vanguard Group, Inc., hold the stock primarily through index funds and ETFs, making them long-term, sticky capital. Also, Mutual Funds and ETFs collectively account for a significant 59.80% of shares outstanding, representing a market value of $6.60 billion as of September 2025.

Investment Motivations: Purity and Growth

Investors are attracted to Entegris, Inc. for three main reasons: its indispensable market position, its demonstrated cash flow, and the clear growth trajectory tied to advanced chip manufacturing. The company is a key supplier of advanced materials and contamination control solutions-a sort of tollbooth operator for the semiconductor industry. As chips get smaller and more complex, the need for materials purity becomes exponentially more critical, which is Entegris, Inc.'s specialty.

The financials in 2025 support this thesis, even with some short-term market headwinds. For the third quarter of 2025, the company reported Non-GAAP diluted Earnings Per Share (EPS) of $0.72 on net sales of $807 million, meeting analyst consensus. More importantly for a growth company, the forward Price-to-Earnings (P/E) ratio of 19.60 is predicated on an expected earnings growth of 24.79% in the next year. That's a strong growth signal in a cyclical industry.

Plus, the company is generating serious cash flow. They reported a record free cash flow of $191.0 million in Q3 2025, which allowed them to pay down $150 million in debt. This strong cash generation is what allows them to maintain a commitment to shareholders, declaring a quarterly cash dividend of $0.10 per share in Q3 2025.

Strategies: Long-Term Growth vs. Tactical Value

Given the institutional dominance, the primary strategy is a long-term growth holding. These investors are betting on the multi-year secular trend of increasing semiconductor complexity. They see the company as a foundational piece of the global technology roadmap, where their materials science expertise is increasingly valuable.

However, not everyone is buying and holding forever. The stock saw a decline of 21.37% from November 2024 to November 2025, which, combined with margin pressure in Q3 2025, attracts tactical value investors and hedge funds. These funds are looking for a temporary dip in a quality asset. For example, the stock dropped 7.03% after the Q3 2025 earnings report because investors focused on the decline in GAAP gross margin to 43.5% from 46.0% a year ago, despite the strong cash flow. This kind of sharp, short-term reaction is where hedge funds like D1 Capital Partners L.P. and Durable Capital Partners LP, who have been active buyers, look to capitalize.

Institutional Ownership and Major Shareholders of Entegris, Inc. (ENTG)

If you're looking at Entegris, Inc. (ENTG), you need to know who the major players are because their moves drive volume and can shape corporate strategy. The short answer is that institutional money-funds, banks, and advisors-holds the vast majority of the company, with institutional ownership sitting at an unusually high 116.02% of shares outstanding as of the most recent data.

This figure, over 100%, isn't a typo; it simply means that a significant portion of the stock is being shorted (sold short) by institutions, which increases the total shares held above the float. This is defintely a key data point for any investor, suggesting a complex mix of long-term conviction and short-term bearish bets in the market.

The Top Institutional Investors in ENTG

The top shareholders of Entegris, Inc. are exactly who you would expect to see in a major semiconductor materials and components supplier: the largest passive and active asset managers in the world. These firms hold massive positions, reflecting the company's status as a foundational piece of the global chip supply chain.

As of the September 30, 2025, 13F filings, the top three institutional holders alone control over 48 million shares, representing a substantial portion of the company's market capitalization, which was around $11.34 billion in Q3 2025.

Here's the quick math on the largest positions:

BlackRock, Inc. and The Vanguard Group, Inc. are primarily index fund managers, meaning their positions are largely passive-they buy because ENTG is a component of major indices like the S&P MidCap 400. Still, their sheer size means any portfolio rebalancing has huge market impact.

Recent Shifts: Who's Buying and Selling in Q3 2025

Institutional buying and selling activity in the most recent quarter (Q3 2025) shows a mixed, but slightly net-positive, sentiment among holders. While 293 institutions decreased their positions, 290 institutions actually increased their holdings.

The total shares bought by increasing institutions (26,338,918 shares) slightly outweighed the shares sold by decreasing institutions (24,622,535 shares). This is a subtle accumulation trend, not a stampede in either direction.

• BlackRock, Inc. reduced its stake by -678,348 shares, a modest -3.824% trim, likely a portfolio adjustment rather than a major shift in conviction.
• The Vanguard Group, Inc. added 443,518 shares, a 2.848% increase, consistent with their role in tracking index growth.
• Capital Research Global Investors established a significant new position of 6,974,133 shares, signaling a strong conviction from a major active manager.
• JPMorgan Chase & Co. made a dramatic cut earlier in the year, removing 3,010,726 shares, a -72.3% reduction in Q2 2025.

When you see a large, active manager like Capital Research Global Investors initiating a position of that size, you pay attention. It suggests they see a clear runway for growth, especially given the company's investments in the U.S. and its position in the semiconductor equipment and materials industry.

The Influence of Institutional Money on ENTG's Strategy

These large institutional holders are not just passive investors; they are critical stakeholders who can influence Entegris, Inc.'s stock price and long-term strategy. Their collective voice matters a lot, especially on capital allocation and major strategic pivots.

For a company like ENTG, whose growth is tied to global semiconductor manufacturing, institutional influence is often felt in two main areas:

• Capital Structure and Governance: Firms like BlackRock and Vanguard often push for best-in-class environmental, social, and governance (ESG) standards, and they have the voting power to influence board elections and executive compensation.
• Strategic Investment Alignment: The institutional base is highly attuned to government incentives. For instance, Entegris, Inc. disclosed $110,000 in lobbying during Q3 2025 related to the implementation of the CHIPS and Science Act. This lobbying effort aligns with the interests of large investors who want the company to maximize benefits from the billions in government funding aimed at boosting domestic semiconductor production.

When you see institutional money accumulating, it's a vote of confidence in the management team's ability to execute on capital-intensive projects, like the announced $700 million investment in the United States, including a new Technology Center in Illinois. Their long-term view is what anchors the stock, even when short-term market volatility is high.

Key Investors and Their Impact on Entegris, Inc. (ENTG)

The investor profile for Entegris, Inc. (ENTG) is dominated by large, passive institutional money, meaning the stock's direction is heavily influenced by the collective sentiment of Wall Street's biggest players, not a single activist. You're looking at a company where institutional ownership sits at a high 116.02% as of October 2025, which is common for a major player in the semiconductor supply chain.

This high ownership level means that the company's stock price movements are defintely tied to institutional rotation-the big funds moving in and out of the sector. When they buy, the stock moves; when they trim, it feels it. It's a passive, but powerful, form of influence.

The Institutional Giants and Their Recent Moves

The top shareholders in Entegris, Inc. are the usual suspects, the massive index and mutual fund managers whose moves reflect broad market strategies rather than a deep, activist dive. As of the September 30, 2025, filings (Q3 2025), the top three institutional holders control a significant chunk of the company's equity, totaling over 48 million shares.

The largest holders are BlackRock, Inc., Vanguard Group Inc, and Price T Rowe Associates Inc /Md/. Their sheer size makes their quarterly 13F filings a critical data point for any investor. Here's a quick look at their Q3 2025 positions:

• BlackRock, Inc.: Holds 17,058,703 shares, but reduced their stake by 678,348 shares in the quarter.
• Vanguard Group Inc: Holds 16,017,716 shares, increasing their position by 443,518 shares.
• Price T Rowe Associates Inc /Md/: Holds 15,344,778 shares, adding 205,263 shares.

It's important to note the split sentiment: BlackRock, Inc. was a net seller, while Vanguard Group Inc and Price T Rowe Associates Inc /Md/ were net buyers. This tells you that while some funds are taking profits or rebalancing, others are still accumulating, signaling a mixed view on the near-term growth trajectory following the Q3 2025 Non-GAAP diluted EPS of $0.72.

Why Funds Are Buying and Selling Now

The recent buying and selling activity is a direct reflection of the semiconductor cycle and the company's positioning within it. For example, in Q2 2025, we saw a massive addition of 3,977,842 shares by Barrow Hanley Mewhinney & Strauss Llc, a significant vote of confidence valued at an estimated $320,812,957. Also in Q2 2025, Duquesne Family Office LLC added 1,645,885 shares. You see conviction in the long-term materials science story here.

On the flip side, some major funds like JPMorgan Chase & Co removed 3,010,726 shares in Q2 2025, and BlackRock, Inc. also removed 2,712,813 shares in the same quarter. This selling often represents a rotation out of capital-intensive semiconductor equipment stocks and into other, perhaps faster-growing, tech segments, especially given the Q4 2025 sales guidance of $790 million to $830 million, which is solid but not explosive.

Investor Influence: Beyond the Trading Floor

While there are no public activist campaigns (Schedule 13D filings) driving a strategic overhaul, the investors still exert real influence. The sheer concentration of shares means their votes matter immensely at the Annual Meeting of Stockholders. At the 2025 meeting, shareholders approved the election of eight directors and ratified the appointment of KPMG LLP as the independent accounting firm for the fiscal year 2025.

More subtly, investors are pushing for better governance. A stockholder proposal for the adoption of simple majority voting received significant support at the 2025 meeting, showing a preference for a more straightforward voting standard. This kind of engagement, while not a headline-grabbing fight, drives long-term value. Plus, the company spent $110,000 on lobbying in Q3 2025, primarily on issues related to the CHIPS and Science Act, which is a direct action to protect and enhance the value of their semiconductor-related business, a move strongly supported by the institutional base. For more on the company's long-term strategy, you can review its Mission Statement, Vision, & Core Values of Entegris, Inc. (ENTG).

Your next step should be to track the next round of 13F filings to see if the net accumulation trend from the Q3 2025 data continues, especially as the stock price sits around $78.28 per share as of mid-November 2025.

Market Impact and Investor Sentiment

The investor sentiment toward Entegris, Inc. (ENTG) is a classic study in market complexity right now: institutional conviction remains high, but near-term market jitters are causing a sharp price correction. You have a semiconductor materials supplier that is mission-critical to the industry's future, yet the stock has declined approximately 27% over the past year, with a quick one-month drop of 21.43% leading into November 2025.

This kind of volatility is a direct result of mixed signals. While the overall institutional ownership is immense-with funds holding a total value of around $13.81 billion-the recent trading activity shows major players moving in opposite directions. Mutual Funds, for example, increased their holdings significantly in September 2025, climbing from 78.53% to 90.63%. That's a strong vote of confidence from long-term capital.

But still, the overall institutional holding slightly dipped to 113.29% in September 2025, a small but notable decrease from the prior month's 114.81%. That's a cautious signal.

The Tug-of-War Among Major Shareholders

Looking at the recent 13F filings from Q2 2025, you see a clear institutional tug-of-war. Some of the largest asset managers are either aggressively accumulating or significantly divesting, which is why the stock price action feels so choppy. This tells me that while the long-term thesis is solid, there's a real debate on the near-term cyclical bottom for the semiconductor industry.

Here's the quick math on who's buying and who's selling:

• Buyers: Barrow Hanley Mewhinney & Strauss LLC added 3,977,842 shares in Q2 2025, a massive increase of 129.7%. Price T Rowe Associates Inc. MD also boosted its stake by 21.1%, acquiring an additional 2,361,065 shares.
• Sellers: JPMorgan Chase & Co. removed 3,010,726 shares from its portfolio, a 72.3% reduction. BlackRock, Inc. also sold off, removing 2,712,813 shares, which was a 13.3% decrease in its position.

Honestly, when you see a firm like BlackRock selling over 2.7 million shares, it defintely gets your attention, but it's often a portfolio rebalancing or risk-off move, not necessarily a fundamental indictment of the company's future. The insider selling by SVP Joseph Colella of 3,577 shares in early November 2025 is a minor data point, but it doesn't help the sentiment.

Market Response to Q3 2025 Results and Analyst Views

The stock market's response has been swift and unforgiving to any sign of weakness. When Entegris, Inc. reported its Q3 2025 financial results, the market reacted negatively, driving the stock down approximately 4.8% in pre-market trading. This wasn't because the company missed its own guidance-it met it-but because it fell short of Wall Street's more optimistic expectations.

Specifically, the reported net sales of $807.1 million for Q3 2025 missed the analyst consensus of $820.3 million. Plus, the Q4 2025 sales outlook of $790 million to $830 million was also below the analyst estimate of $844.2 million. Soft guidance always hurts. The GAAP diluted earnings per share (EPS) for Q3 2025 was $0.46, while the non-GAAP diluted EPS came in at $0.72.

Analyst perspectives are still mostly positive on the long-term picture, despite the near-term headwinds. The average price target is a 'Hold' at $97.57, but the median target is actually higher at $101.0. Mizuho, for instance, issued an 'Outperform' rating with a $108.0 target in October 2025. What this estimate hides is the conviction that Entegris, Inc. is a materials play on the increasing complexity of semiconductor manufacturing.

The core thesis for the bulls is that the company is a leader in advanced materials-things like CMP slurries and selective etch-which means its 'content per wafer' is increasing as devices become more complex. This allows for higher Average Selling Prices (ASPs) and better gross margins down the road. The consensus narrative suggests the stock is 27.6% Undervalued based on its long-term growth trajectory. So, the big money is buying the future, even if the present is a little bumpy.
