Is Santos (ASX:STO) 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.' 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. As with many other companies Santos Limited (ASX:STO) makes use of debt. But is this debt a concern to shareholders?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is Santos's Debt?

As you can see below, at the end of June 2024, Santos had US$5.56b of debt, up from US$4.93b a year ago. Click the image for more detail. However, because it has a cash reserve of US$1.66b, its net debt is less, at about US$3.90b.

How Strong Is Santos' Balance Sheet?

The latest balance sheet data shows that Santos had liabilities of US$2.78b due within a year, and liabilities of US$11.1b falling due after that. Offsetting this, it had US$1.66b in cash and US$892.0m in receivables that were due within 12 months. So its liabilities total US$11.4b more than the combination of its cash and short-term receivables.

This deficit is considerable relative to its very significant market capitalization of US$15.5b, so it does suggest shareholders should keep an eye on Santos' use of debt. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.

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).

Santos has net debt of just 1.2 times EBITDA, suggesting it could ramp leverage without breaking a sweat. And remarkably, despite having net debt, it actually received more in interest over the last twelve months than it had to pay. So there's no doubt this company can take on debt while staying cool as a cucumber. In fact Santos's saving grace is its low debt levels, because its EBIT has tanked 33% in the last twelve months. Falling earnings (if the trend continues) could eventually make even modest debt quite risky. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Santos 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 most recent three years, Santos recorded free cash flow worth 73% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This cold hard cash means it can reduce its debt when it wants to.

Our View

We feel some trepidation about Santos's difficulty EBIT growth rate, but we've got positives to focus on, too. To wit both its interest cover and conversion of EBIT to free cash flow were encouraging signs. We think that Santos's debt does make it a bit risky, after considering the aforementioned data points together. Not all risk is bad, as it can boost share price returns if it pays off, but this debt risk is worth keeping in mind. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet. To that end, you should be aware of the 1 warning sign we've spotted with Santos .
