Is Mesa Laboratories (NASDAQ:MLAB) A Risky Investment?

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, Mesa Laboratories, Inc. (NASDAQ:MLAB) does carry debt. But should shareholders be worried about its use of debt?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. 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. The first step when considering a company's debt levels is to consider its cash and debt together.

How Much Debt Does Mesa Laboratories Carry?

The image below, which you can click on for greater detail, shows that Mesa Laboratories had debt of US$175.5m at the end of June 2023, a reduction from US$216.6m over a year. However, because it has a cash reserve of US$33.8m, its net debt is less, at about US$141.7m.

How Healthy Is Mesa Laboratories' Balance Sheet?

According to the last reported balance sheet, Mesa Laboratories had liabilities of US$39.1m due within 12 months, and liabilities of US$215.8m due beyond 12 months. Offsetting these obligations, it had cash of US$33.8m as well as receivables valued at US$35.6m due within 12 months. So it has liabilities totalling US$185.5m more than its cash and near-term receivables, combined.

Mesa Laboratories has a market capitalization of US$575.6m, 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 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).

While we wouldn't worry about Mesa Laboratories's net debt to EBITDA ratio of 3.5, we think its super-low interest cover of 1.5 times is a sign of high leverage. In large part that's due to the company's significant depreciation and amortisation charges, which arguably mean its EBITDA is a very generous measure of earnings, and its debt may be more of a burden than it first appears. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. The good news is that Mesa Laboratories grew its EBIT a smooth 63% over the last twelve months. Like a mother's loving embrace of a newborn that sort of growth builds resilience, putting the company in a stronger position to manage its debt. 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 Mesa Laboratories 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 it's worth checking how much of that EBIT is backed by free cash flow. Happily for any shareholders, Mesa Laboratories actually produced more free cash flow than EBIT over the last three years. There's nothing better than incoming cash when it comes to staying in your lenders' good graces.

Our View

Happily, Mesa Laboratories's impressive conversion of EBIT to free cash flow implies it has the upper hand on its debt. But we must concede we find its interest cover has the opposite effect. Looking at all the aforementioned factors together, it strikes us that Mesa Laboratories can handle its debt fairly comfortably. Of course, while this leverage can enhance returns on equity, it does bring more risk, so it's worth keeping an eye on this one. Above most other metrics, we think its important to track how fast earnings per share is growing, if at all. If you've also come to that realization, you're in luck, because today you can view this interactive graph of Mesa Laboratories's earnings per share history for free.
