Is Southwest Gas Holdings (SWX) Priced Too Richly For Its Earnings?

Listen to the news

Southwest Gas Holdings has given shareholders a strong ride in recent years, which puts a brighter spotlight on whether the current share price lines up with what its earnings can reasonably support. With the stock now trading at US$87.45, the key issue is how that market tag stacks up against the profit power of the underlying utility business.

  • Over the past 3 years the stock has returned 67.9%, which raises a clear question about whether earnings have kept pace with that kind of share price climb.
  • The group relies on a regulated gas distribution model, so the way its allowed returns, operating costs, and capital spending translate into net income may support or limit how much investors are prepared to pay for each dollar of earnings.

The issue now is whether Southwest Gas Holdings' current market price is adequately backed by its earnings when judged against the Fair Ratio benchmark.

Is Southwest Gas Holdings Getting Expensive on Earnings?

The P/E ratio usually works well for a regulated utility such as Southwest Gas Holdings because earnings are a central focus for both regulators and investors. At a current P/E of 22.3x, the stock trades above the Gas Utilities industry average of 14.0x and above the broader peer group on about 16.3x earnings. That places a relatively rich price on each dollar of the company’s profit compared with many similar gas distributors.

The Fair Ratio, which reflects what investors might expect to pay for Southwest Gas Holdings once its growth outlook, margins, size, and risk profile are accounted for, implies a lower earnings multiple than where the shares now change hands. The present 22.3x P/E therefore sits above that tailored benchmark, so buyers are paying a premium versus what this model suggests for the utility’s fundamentals. That leaves the question of whether the quality and resilience of Southwest Gas Holdings' earnings justify paying up on this measure, or whether the premium multiple may be asking too much at the current price.
