Is Minerals Technologies (NYSE:MTX) Using Too Much Debt?

Legendary fund manager Li Lu (who Charlie Munger backed) once said, '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. We can see that Minerals Technologies Inc. (NYSE:MTX) does use debt in its business. 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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth at high rates of return. When we think about a company's use of debt, we first look at cash and debt together.

What Is Minerals Technologies's Net Debt?

You can click the graphic below for the historical numbers, but it shows that Minerals Technologies had US$933.9m of debt in December 2019, down from US$1.02b, one year before. However, it also had US$243.2m in cash, and so its net debt is US$690.7m.

A Look At Minerals Technologies's Liabilities

According to the last reported balance sheet, Minerals Technologies had liabilities of US$398.5m due within 12 months, and liabilities of US$1.28b due beyond 12 months. Offsetting these obligations, it had cash of US$243.2m as well as receivables valued at US$376.2m due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$1.06b.

This deficit is considerable relative to its market capitalization of US$1.19b, so it does suggest shareholders should keep an eye on Minerals Technologies's 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).

Minerals Technologies has net debt worth 2.1 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 5.4 times the interest expense. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. The bad news is that Minerals Technologies saw its EBIT decline by 10% over the last year. If earnings continue to decline at that rate then handling the debt will be more difficult than taking three children under 5 to a fancy pants restaurant. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Minerals Technologies 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 we clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, Minerals Technologies produced sturdy free cash flow equating to 57% of its EBIT, about what we'd expect. This cold hard cash means it can reduce its debt when it wants to.

Our View

On the face of it, Minerals Technologies's level of total liabilities left us tentative about the stock, and its EBIT growth rate was no more enticing than the one empty restaurant on the busiest night of the year. But at least it's pretty decent at converting EBIT to free cash flow; that's encouraging. Once we consider all the factors above, together, it seems to us that Minerals Technologies's debt is making it a bit risky. Some people like that sort of risk, but we're mindful of the potential pitfalls, so we'd probably prefer it carry less debt. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it.
