Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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. As with many other companies Minerals Technologies Inc. (NYSE:MTX) makes use of debt. But the more important question is: how much risk is that debt creating?

When Is Debt A Problem?

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, plenty of companies use debt to fund growth, without any negative consequences. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Minerals Technologies's Debt?

The image below, which you can click on for greater detail, shows that Minerals Technologies had debt of US$991.4m at the end of June 2024, a reduction from US$1.04b over a year. However, it also had US$316.4m in cash, and so its net debt is US$675.0m.

A Look At Minerals Technologies' Liabilities

According to the last reported balance sheet, Minerals Technologies had liabilities of US$453.6m due within 12 months, and liabilities of US$1.19b due beyond 12 months. Offsetting this, it had US$316.4m in cash and US$405.1m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$927.0m.

This deficit isn't so bad because Minerals Technologies is worth US$2.52b, and thus could probably raise enough capital to shore up 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).

Minerals Technologies has net debt worth 1.8 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 4.6 times the interest expense. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. One way Minerals Technologies could vanquish its debt would be if it stops borrowing more but continues to grow EBIT at around 14%, as it did over the last year. 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 Minerals Technologies 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 the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Looking at the most recent three years, Minerals Technologies recorded free cash flow of 39% of its EBIT, which is weaker than we'd expect. That weak cash conversion makes it more difficult to handle indebtedness.

Our View

On our analysis Minerals Technologies's EBIT growth rate should signal that it won't have too much trouble with its debt. However, our other observations weren't so heartening. For instance it seems like it has to struggle a bit to cover its interest expense with its EBIT. When we consider all the factors mentioned above, we do feel a bit cautious about Minerals Technologies's use of debt. While we appreciate debt can enhance returns on equity, we'd suggest that shareholders keep close watch on its debt levels, lest they increase. 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 Minerals Technologies .

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.
