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, Scorpio Tankers Inc. (NYSE:STNG) does carry debt. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. 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. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

How Much Debt Does Scorpio Tankers Carry?

You can click the graphic below for the historical numbers, but it shows that as of June 2024 Scorpio Tankers had US$904.6m of debt, an increase on US$655.4m, over one year. However, it does have US$224.6m in cash offsetting this, leading to net debt of about US$680.0m.

How Strong Is Scorpio Tankers' Balance Sheet?

The latest balance sheet data shows that Scorpio Tankers had liabilities of US$231.5m due within a year, and liabilities of US$840.2m falling due after that. Offsetting these obligations, it had cash of US$224.6m as well as receivables valued at US$227.7m due within 12 months. So its liabilities total US$619.3m more than the combination of its cash and short-term receivables.

Given Scorpio Tankers has a market capitalization of US$3.18b, it's hard to believe these liabilities pose much threat. However, we do think it is worth keeping an eye on its balance sheet strength, as it may change over time.

We use two main ratios to inform us about debt levels relative to earnings. The first is net debt divided by earnings before interest, tax, depreciation, and amortization (EBITDA), while the second is how many times its earnings before interest and tax (EBIT) covers its interest expense (or its interest cover, for short). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

While Scorpio Tankers's low debt to EBITDA ratio of 0.75 suggests only modest use of debt, the fact that EBIT only covered the interest expense by 5.8 times last year does give us pause. So we'd recommend keeping a close eye on the impact financing costs are having on the business. Shareholders should be aware that Scorpio Tankers's EBIT was down 26% last year. If that decline continues then paying off debt will be harder than selling foie gras at a vegan convention. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Scorpio Tankers can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So we always check how much of that EBIT is translated into free cash flow. Over the last three years, Scorpio Tankers actually produced more free cash flow than EBIT. That sort of strong cash generation warms our hearts like a puppy in a bumblebee suit.

Our View

Scorpio Tankers's EBIT growth rate was a real negative on this analysis, although the other factors we considered were considerably better. There's no doubt that its ability to to convert EBIT to free cash flow is pretty flash. When we consider all the elements mentioned above, it seems to us that Scorpio Tankers is managing its debt quite well. But a word of caution: we think debt levels are high enough to justify ongoing monitoring. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it. For example Scorpio Tankers has 2 warning signs (and 1 which is concerning) we think you should know about.

At the end of the day, it's often better to focus on companies that are free from net debt. You can access our special list of such companies (all with a track record of profit growth). It's free.
