Is Southwest Gas Holdings (NYSE:SWX) A Risky Investment?

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.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. Importantly, Southwest Gas Holdings, Inc. (NYSE:SWX) does carry debt. But the real question is whether this debt is making the company risky.

When Is Debt A Problem?

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 common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. When we examine debt levels, we first consider both cash and debt levels, together.

How Much Debt Does Southwest Gas Holdings Carry?

You can click the graphic below for the historical numbers, but it shows that as of March 2024 Southwest Gas Holdings had US$5.34b of debt, an increase on US$5.09b, over one year. On the flip side, it has US$458.0m in cash leading to net debt of about US$4.88b.

How Strong Is Southwest Gas Holdings' Balance Sheet?

The latest balance sheet data shows that Southwest Gas Holdings had liabilities of US$1.72b due within a year, and liabilities of US$6.81b falling due after that. Offsetting these obligations, it had cash of US$458.0m as well as receivables valued at US$908.8m due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$7.16b.

Given this deficit is actually higher than the company's market capitalization of US$5.31b, we think shareholders really should watch Southwest Gas Holdings's debt levels, like a parent watching their child ride a bike for the first time. 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.

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). The advantage of this approach is that we take into account both the absolute quantum of debt (with net debt to EBITDA) and the actual interest expenses associated with that debt (with its interest cover ratio).

Weak interest cover of 1.9 times and a disturbingly high net debt to EBITDA ratio of 5.4 hit our confidence in Southwest Gas Holdings like a one-two punch to the gut. This means we'd consider it to have a heavy debt load. More concerning, Southwest Gas Holdings saw its EBIT drop by 2.6% in the last twelve months. If it keeps going like that paying off its debt will be like running on a treadmill -- a lot of effort for not much advancement. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Southwest Gas Holdings can strengthen its balance sheet over time. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. 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 net debt to EBITDA 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. Having said that, its ability to grow its EBIT isn't such a worry. It's also worth noting that Southwest Gas Holdings is in the Gas Utilities industry, which is often considered to be quite defensive. After considering the datapoints discussed, we think Southwest Gas Holdings has too much debt. That sort of riskiness is ok for some, but it certainly doesn't float our boat. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it. These risks can be hard to spot. Every company has them, and we've spotted 2 warning signs for Southwest Gas Holdings (of which 1 is concerning!) you should know about.

When all is said and done, sometimes its easier to focus on companies that don't even need debt. Readers can access a list of growth stocks with zero net debt 100% free, right now.
