Southwest Gas Holdings (NYSE:SWX) Takes On Some Risk With Its Use Of Debt

The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. We note that Southwest Gas Holdings, Inc. (NYSE:SWX) does have debt on its balance sheet. But should shareholders be worried about its use of debt?

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

Why Does Debt Bring Risk?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. If things get really bad, the lenders can take control of the business. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Of course, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Southwest Gas Holdings's Debt?

As you can see below, Southwest Gas Holdings had US$5.05b of debt at March 2025, down from US$5.34b a year prior. However, it does have US$406.3m in cash offsetting this, leading to net debt of about US$4.64b.

How Strong Is Southwest Gas Holdings' Balance Sheet?

According to the last reported balance sheet, Southwest Gas Holdings had liabilities of US$1.81b due within 12 months, and liabilities of US$6.51b due beyond 12 months. Offsetting these obligations, it had cash of US$406.3m as well as receivables valued at US$761.8m due within 12 months. So it has liabilities totalling US$7.15b more than its cash and near-term receivables, combined.

When you consider that this deficiency exceeds the company's US$5.82b market capitalization, you might well be inclined to review the balance sheet intently. Hypothetically, extremely heavy dilution would be required if the company were forced to pay down its liabilities by raising capital at the current share price.

View our latest analysis for Southwest Gas Holdings

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (interest cover). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

While Southwest Gas Holdings's debt to EBITDA ratio (4.7) suggests that it uses some debt, its interest cover is very weak, at 2.0, suggesting high leverage. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. On a slightly more positive note, Southwest Gas Holdings grew its EBIT at 18% over the last year, further increasing its ability to manage debt. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Southwest Gas Holdings's ability to maintain a healthy balance sheet going forward. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, Southwest Gas Holdings saw substantial negative free cash flow, in total. While that may be a result of expenditure for growth, it does make the debt far more risky.

Our View

On the face of it, Southwest Gas Holdings's interest cover left us tentative about the stock, and its conversion of EBIT to free cash flow was no more enticing than the one empty restaurant on the busiest night of the year. But on the bright side, its EBIT growth rate is a good sign, and makes us more optimistic. We should also note that Gas Utilities industry companies like Southwest Gas Holdings commonly do use debt without problems. We're quite clear that we consider Southwest Gas Holdings to be really rather risky, as a result of its balance sheet health. For this reason we're pretty cautious about the stock, and we think shareholders should keep a close eye on its liquidity.
