Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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 HF Sinclair Corporation (NYSE:DINO) makes use of debt. But the real question is whether this debt is making the company risky.

What Risk Does Debt Bring?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. When we think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does HF Sinclair Carry?

You can click the graphic below for the historical numbers, but it shows that HF Sinclair had US$2.67b of debt in September 2024, down from US$3.17b, one year before. However, because it has a cash reserve of US$1.23b, its net debt is less, at about US$1.44b.

How Strong Is HF Sinclair's Balance Sheet?

The latest balance sheet data shows that HF Sinclair had liabilities of US$2.96b due within a year, and liabilities of US$4.25b falling due after that. On the other hand, it had cash of US$1.23b and US$1.38b worth of receivables due within a year. So it has liabilities totalling US$4.61b more than its cash and near-term receivables, combined.

HF Sinclair has a market capitalization of US$7.96b, so it could very likely raise cash to ameliorate its balance sheet, if the need arose. However, it is still worthwhile taking a close look at its ability to pay off debt.

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). 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).

Looking at its net debt to EBITDA of 1.4 and interest cover of 5.2 times, it seems to us that HF Sinclair is probably using debt in a pretty reasonable way. But the interest payments are certainly sufficient to have us thinking about how affordable its debt is. Shareholders should be aware that HF Sinclair's EBIT was down 86% last year. If that earnings trend continues then paying off its debt will be about as easy as herding cats on to a roller coaster. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if HF Sinclair 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.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the last three years, HF Sinclair recorded free cash flow worth a fulsome 81% of its EBIT, which is stronger than we'd usually expect. That positions it well to pay down debt if desirable to do so.

Our View

Neither HF Sinclair's ability to grow its EBIT nor its level of total liabilities gave us confidence in its ability to take on more debt. But its conversion of EBIT to free cash flow tells a very different story, and suggests some resilience. Looking at all the angles mentioned above, it does seem to us that HF Sinclair is a somewhat risky investment as a result of its debt. That's not necessarily a bad thing, since leverage can boost returns on equity, but it is something to be aware of. There's no doubt that we learn most about debt from the balance sheet. However, not all investment risk resides within the balance sheet - far from it. For instance, we've identified 3 warning signs for HF Sinclair that you should be aware of.
