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. Importantly, Minerals Technologies Inc. (NYSE:MTX) does carry debt. But should shareholders be worried about its use of debt?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. 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. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Minerals Technologies's Debt?

You can click the graphic below for the historical numbers, but it shows that Minerals Technologies had US$982.9m of debt in September 2024, down from US$1.04b, one year before. However, it does have US$324.5m in cash offsetting this, leading to net debt of about US$658.4m.

A Look At Minerals Technologies' Liabilities

According to the last reported balance sheet, Minerals Technologies had liabilities of US$464.0m due within 12 months, and liabilities of US$1.19b due beyond 12 months. Offsetting these obligations, it had cash of US$324.5m as well as receivables valued at US$412.5m due within 12 months. So its liabilities total US$912.2m more than the combination of its cash and short-term receivables.

While this might seem like a lot, it is not so bad since Minerals Technologies has a market capitalization of US$2.43b, and so it could probably strengthen its balance sheet by raising capital if it needed to. 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 4.8 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 10%, as it did over the last year. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Minerals Technologies's ability to maintain a healthy balance sheet going forward. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. In the last three years, Minerals Technologies's free cash flow amounted to 39% of its EBIT, less than we'd expect. That's not great, when it comes to paying down debt.

Our View

Both Minerals Technologies's ability to to grow its EBIT and its net debt to EBITDA gave us comfort that it can handle its debt. On the other hand, its conversion of EBIT to free cash flow makes us a little less comfortable about its debt. When we consider all the factors mentioned above, we do feel a bit cautious about Minerals Technologies's use of debt. While debt does have its upside in higher potential returns, we think shareholders should definitely consider how debt levels might make the stock more risky.
