Improved Revenue Outlook And Margin Pressure Will Shape Earnings Prospects

Key Takeaways

• Expansion in the Southwest and major infrastructure projects support sustained demand and future earnings growth.
  
• Regulatory tailwinds, cost discipline, and restructuring efforts are improving margin stability, balance sheet strength, and profitability.
  
• Decarbonization trends, regulatory caps, project execution risks, business divestitures, and rising competition from alternative energy threaten growth prospects, profitability, and revenue stability.

Catalysts

Through its subsidiaries, purchases, distributes, and transports natural gas for residential, commercial, and industrial customers in Arizona, Nevada, and California.

• Robust customer growth facilitated by ongoing population and economic expansion in the Southwest, with 40,000 new meter connections in the last 12 months, suggests extended demand for natural gas in core service territories, directly underpinning long-term revenue and earnings growth.
  
• Accelerated infrastructure investment opportunities, exemplified by the Great Basin pipeline expansion project with potential $1.2–$1.6 billion in new capital expenditures, are expected to drive significant rate base growth, supporting higher future regulated revenue and earnings.
  
• Favorable regulatory developments such as Nevada's new alternative ratemaking legislation and progress on formula rates in Arizona and California provide visibility into faster cost recovery and mitigated regulatory lag, which should enhance margin stability and earnings predictability.
  
• Cost discipline demonstrated through O&M increases below inflation and a focus on operational optimization reinforce the ability to expand net profit margins over time, translating to improved long-term profitability.
  
• Ongoing deleveraging and the pending full separation of Centuri should meaningfully strengthen the company's balance sheet and reduce interest expenses, which is expected to improve net margins and free up capital for reinvestment and/or shareholder returns.

Southwest Gas Holdings Future Earnings and Revenue Growth

Assumptions

How have these above catalysts been quantified?

• Analysts are assuming Southwest Gas Holdings's revenue will grow by 10.8% annually over the next 3 years.
• Analysts assume that profit margins will increase from 13.4% today to 18.0% in 3 years time.
• Analysts expect earnings to reach $436.3 million (and earnings per share of $5.97) by about June 2029, up from $238.9 million today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the price target of the analysts, the company would need to trade at a PE ratio of 20.6x on those 2029 earnings, down from 26.8x today. This future PE is greater than the current PE for the US Gas Utilities industry at 16.7x.
• Analysts expect the number of shares outstanding to grow by 0.55% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 7.11%, as per the Simply Wall St company report.

Risks

• Accelerating decarbonization and electrification trends-driven by regulatory, policy, and consumer shifts-threaten long-term demand for natural gas, increasing the risk of revenue stagnation and future stranded asset write-downs.
  
• The imposition of stricter environmental regulations and caps on capital recovery mechanisms (e.g., Arizona's $50 million SIM cap) will raise compliance costs and could constrain the company's ability to recover necessary infrastructure investments, pressuring profitability and earnings growth.
  
• Execution risks remain high around large-scale expansion projects (such as the $1.2–$1.6 billion Great Basin pipeline), where delays, cost overruns, or failure to secure long-term shipping agreements could undermine return on invested capital and materially impact earnings.
  
• Ongoing separation and divestiture of the Centuri segment heightens financial complexity and exposes Southwest Gas Holdings to risks of reduced revenue diversification, as well as potential volatility in net income during and after the transition.
  
• Long-term topline sales are at risk from continued building electrification mandates, increased competition from alternative energy technologies, and the potential for regulatory lag-particularly if future rate adjustments do not align with input cost inflation-collectively placing downward pressure on both revenues and net margins.

Valuation

How have all the factors above been brought together to estimate a fair value?

• The analysts have a consensus price target of $99.25 for Southwest Gas Holdings based on their expectations of its future earnings growth, profit margins and other risk factors.
• In order for you to agree with the analysts, you'd need to believe that by 2029, revenues will be $2.4 billion, earnings will come to $436.3 million, and it would be trading on a PE ratio of 20.6x, assuming you use a discount rate of 7.1%.
• Given the current share price of $88.48, the analyst price target of $99.25 is 10.9% higher.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
