Here's the quick math on the major holders, based on Q3 2025 filings:

Investment Motivations: Stability and Growth in a Regulated Market

Investors are drawn to Southwest Gas Holdings for a few clear reasons, all tied to its regulated utility status in high-growth territories like Arizona, Nevada, and California.

First, it's the dividend income. The company has paid a quarterly dividend continuously since 1956. The annualized dividend is currently $2.48 per share, translating to a yield of approximately 3.11% in late 2025. That's a reliable income stream for pension funds and income-focused retail portfolios.

Second, regulated asset growth is the core catalyst. The company is actively investing in its infrastructure, with capital expenditures projected at approximately $880 million for the 2025 fiscal year. This investment, which regulators allow the company to earn a return on, is expected to drive the 2025-2029 adjusted net income Compound Annual Growth Rate (CAGR) between 6.0% and 8.0%. Plus, customer growth is strong, adding around 40,000 first-time meter sets over the last twelve months.

Finally, the company's improved financial footing following the Centuri separation is a big draw. S&P upgraded the credit rating for the utility's senior unsecured debt to BBB+ with a stable outlook, which signals lower risk to bond and equity holders alike.

Investment Strategies: Income, Value, and Activism

The strategies employed by the diverse investor base reflect the dual nature of Southwest Gas Holdings: a stable utility and a company undergoing a strategic transformation.

The majority of institutional money, particularly from index funds, employs a simple long-term holding strategy, treating SWX as a defensive, low-volatility utility stock (beta of 0.62). They are classic value investors focused on the predictable earnings and the robust dividend yield.

However, the hedge fund activity, led by firms like Icahn Associates Corporation, is a clear sign of an event-driven or activist value strategy. These investors see a disconnect between the stock's current price and its potential value, often pushing for asset sales, cost cuts, or changes in management to unlock that value. Their goal is a quicker, more dramatic return than a typical utility investor seeks.

What this estimate hides is the tension: the stock is trading at a premium to some discounted cash flow (DCF) fair value estimates, but the full-year 2025 net income guidance is expected toward the top end of the $265 million to $275 million range. This creates an opportunity for short-term traders to play the gap between the strong full-year outlook and the Q3 2025 earnings per share miss of $0.06 versus the $0.09 forecast. It's a tug-of-war between stability and strategic change.

Key Investors and Their Impact on Southwest Gas Holdings, Inc. (SWX)

The key takeaway is that institutional investors own a massive chunk of the company, and the influence of one billionaire, Carl C. Icahn, has permanently reshaped its structure.

Institutional investors-the big funds and money managers-hold about 92.77% of Southwest Gas Holdings, Inc.'s stock, which is typical for a stable utility but also means a few key players can swing the stock price and push for strategic shifts. You see names like Bank of New York Mellon Corp and Intech Investment Management LLC increasing their stakes, signaling confidence in the company's new direction.

• Corvex Management LP: An activist hedge fund that has recently taken a significant position.

The Activist Catalyst: Carl C. Icahn's Influence

Carl C. Icahn's involvement has been the single biggest driver of change for Southwest Gas Holdings, Inc. over the last few years. His activism, often focused on unlocking shareholder value (a fancy term for selling off non-core assets), led directly to the separation of the utility infrastructure services business, Centuri Holdings, Inc. (CTRI), from the core regulated natural gas utility. Honestly, this is why the stock is moving. You can see how the company's financial health is changing in Breaking Down Southwest Gas Holdings, Inc. (SWX) Financial Health: Key Insights for Investors.

This activist pressure is not just talk; it changes the board and management. Icahn Enterprises secured at least three board seats, and after he highlighted that the former CEO's pay had increased by 132% while the stock only rose 15% over a period, the CEO resigned soon after. That's a concrete example of how a major shareholder can directly impact C-suite decisions and corporate governance. The goal was to turn Southwest Gas Holdings, Inc. into a pure-play, fully regulated natural gas business, which is a much simpler, lower-risk profile for investors.

The core of the recent strategic execution is the Centuri divestiture. Following public and private offerings in 2025, Southwest Gas Holdings, Inc. reduced its ownership of Centuri Holdings, Inc. to approximately 52%. The net proceeds from these offerings were used to reduce the company's debt by over $470 million, a crucial balance sheet strengthening move that directly benefits shareholders.

Recent Investor Moves and What They Signal

The most telling recent move in the 2025 fiscal year came from the primary activist himself. Carl C. Icahn sold a substantial block of shares, liquidating 1,500,000 shares on September 25, 2025, at an average price of $77.91 per share. The total value of that sale was a staggering $116,865,000.00. This reduced his position by 19.91%, but he still owns a massive stake of 6,032,604 shares.

Here's the quick math: selling a chunk after a major strategic win (the Centuri spin-off) suggests he's monetizing some of the value he helped create, but his remaining position, valued at approximately $470 million, shows he is defintely still deeply committed to the company's future. You don't hold that many shares if you think the story is over.

Also, other funds are stepping in. Corvex Management LP, another activist-oriented fund, established a new position in Q2 2025, acquiring shares valued at $19,449,861. This is a clear signal that other smart money believes there's still value to be unlocked in the newly simplified utility structure. They are buying the new story. This table summarizes the notable Q2/Q3 2025 activity:

The clear action for you is to map your investment thesis against this new, pure-play utility profile. The activist pressure has already forced the biggest structural change, so the focus now shifts to regulatory progress and operational efficiency. Finance: review the Q3 2025 earnings report for any new guidance on capital expenditure and rate base growth by next week.

Market Impact and Investor Sentiment

You're looking at Southwest Gas Holdings, Inc. (SWX) right now and the investor profile is defintely shifting, moving from a complex conglomerate to a focused, regulated utility. The overall sentiment among major shareholders is cautiously positive, largely driven by the successful, full separation of its construction services business, Centuri Holdings, Inc., which closed in the third quarter of 2025. This strategic move fundamentally de-risked the balance sheet, which is what utility investors crave.

The market has responded by pushing the stock to a 52-week high of $82.1 USD in November 2025, reflecting renewed confidence in the pure-play natural gas distribution model. Institutional investors own a commanding stake, with ownership hovering around 92.77% of the company's stock, showing that the big money is betting on this new, streamlined focus.

Recent Market Reactions and Key Investor Moves

The most significant market reaction came after the company completed the Centuri divestiture. Here's the quick math: the final sell-downs generated approximately $879 million in net proceeds, which Southwest Gas Holdings used to fully repay its term loan and bank debt. This deleveraging immediately strengthened the company's financial profile, leading S&P Global Ratings to upgrade the company's credit rating to 'BBB+' with a stable outlook. That's a clear signal from the credit market that the company is on solid footing.

Still, the picture isn't uniform. Activist investor Carl C. Icahn, a major shareholder, sold 1,500,000 shares in September 2025 for roughly $116.9 million, cutting his position by nearly 20%. While large sales can spook the market, this move is likely a profit-taking event following the restructuring success he advocated for, rather than a vote of no confidence in the regulated utility business itself. The stock's resilience suggests the market saw it that way, too.

• Stock hit 52-week high of $82.1 USD in November 2025.
• S&P Global Ratings upgraded credit to 'BBB+' post-Centuri sale.
• Icahn Group reduced stake by nearly 20% in Q3 2025.

Analyst Perspectives on the New SWX Narrative

Analysts are now mapping the near-term opportunities to the company's core regulated business. The consensus rating is a 'Moderate Buy,' with an average price target of $84.50. Firms like Mizuho initiated coverage with an 'Outperform' rating and a $91.00 target, citing the strengthened balance sheet and clear growth path.

The positive outlook is grounded in the company's operational performance, especially the utility's ability to secure rate relief and drive customer growth. The trailing 12-month utility Return on Equity (ROE) reached 8.3%, a key metric for utility investors, and the company added approximately 40,000 new meter sets in the 12 months leading up to Q3 2025. This steady customer base growth in high-demand territories-Arizona, Nevada, and California-is the engine of future earnings.

What this estimate hides is the Q3 2025 earnings per diluted share (EPS) from continuing operations, which was $0.06, missing the analyst consensus of $0.09. However, the consolidated diluted EPS was a massive $3.74, due to the one-time gain from the Centuri sale, which is a big-picture win. Management affirmed its full-year 2025 net income guidance of $265 million to $275 million, now expecting to land toward the top end of that range, which is a solid sign of operational discipline. For a deeper dive into the company's long-term strategy, you should review their Mission Statement, Vision, & Core Values of Southwest Gas Holdings, Inc. (SWX).
