Here's Why Sotera Health (NASDAQ:SHC) Has A Meaningful Debt Burden

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.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. Importantly, Sotera Health Company (NASDAQ:SHC) does carry debt. But is this debt a concern to shareholders?

When Is Debt Dangerous?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. When we think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does Sotera Health Carry?

The chart below, which you can click on for greater detail, shows that Sotera Health had US$2.23b in debt in September 2024; about the same as the year before. However, it also had US$307.4m in cash, and so its net debt is US$1.92b.

How Strong Is Sotera Health's Balance Sheet?

We can see from the most recent balance sheet that Sotera Health had liabilities of US$195.5m falling due within a year, and liabilities of US$2.48b due beyond that. On the other hand, it had cash of US$307.4m and US$176.6m worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$2.19b.

This is a mountain of leverage relative to its market capitalization of US$3.63b. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.

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).

While Sotera Health's debt to EBITDA ratio (3.5) suggests that it uses some debt, its interest cover is very weak, at 2.3, suggesting high leverage. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. On the other hand, Sotera Health grew its EBIT by 29% in the last year. If sustained, this growth should make that debt evaporate like a scarce drinking water during an unnaturally hot summer. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine Sotera Health's ability to maintain a healthy balance sheet going forward.

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. Considering the last three years, Sotera Health actually recorded a cash outflow, overall. Debt is usually more expensive, and almost always more risky in the hands of a company with negative free cash flow. Shareholders ought to hope for an improvement.

Our View

To be frank both Sotera Health's interest cover and its track record of converting EBIT to free cash flow make us rather uncomfortable with its debt levels. But on the bright side, its EBIT growth rate is a good sign, and makes us more optimistic. Looking at the balance sheet and taking into account all these factors, we do believe that debt is making Sotera Health stock a bit risky. That's not necessarily a bad thing, but we'd generally feel more comfortable with less leverage. 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. Be aware that Sotera Health is showing 2 warning signs in our investment analysis , and 1 of those is concerning...
