We Think Mercury Systems (NASDAQ:MRCY) Is Taking Some Risk With Its Debt

David Iben put it well when he said, 'Volatility is not a risk we care about. What we care about is avoiding the permanent loss of capital.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. As with many other companies Mercury Systems, Inc. (NASDAQ:MRCY) makes use of debt. But should shareholders be worried about its use of debt?

Why Does Debt Bring Risk?

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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Mercury Systems's Debt?

You can click the graphic below for the historical numbers, but it shows that as of December 2022 Mercury Systems had US$511.5m of debt, an increase on US$451.5m, over one year. However, it also had US$76.9m in cash, and so its net debt is US$434.6m.

How Healthy Is Mercury Systems' Balance Sheet?

The latest balance sheet data shows that Mercury Systems had liabilities of US$200.6m due within a year, and liabilities of US$603.3m falling due after that. Offsetting this, it had US$76.9m in cash and US$479.3m in receivables that were due within 12 months. So its liabilities total US$247.6m more than the combination of its cash and short-term receivables.

Since publicly traded Mercury Systems shares are worth a total of US$3.20b, it seems unlikely that this level of liabilities would be a major threat. However, we do think it is worth keeping an eye on its balance sheet strength, as it may change over time.

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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

While we wouldn't worry about Mercury Systems's net debt to EBITDA ratio of 3.0, we think its super-low interest cover of 2.5 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. Even worse, Mercury Systems saw its EBIT tank 32% over the last 12 months. If earnings keep going like that over the long term, it has a snowball's chance in hell of paying off that 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 Mercury Systems 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.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So we always check how much of that EBIT is translated into free cash flow. Considering the last three years, Mercury Systems actually recorded a cash outflow, overall. Debt is far more risky for companies with unreliable free cash flow, so shareholders should be hoping that the past expenditure will produce free cash flow in the future.

Our View

To be frank both Mercury Systems's conversion of EBIT to free cash flow and its track record of (not) growing its EBIT make us rather uncomfortable with its debt levels. But at least it's pretty decent at staying on top of its total liabilities; that's encouraging. Overall, we think it's fair to say that Mercury Systems has enough debt that there are some real risks around the balance sheet. If all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. There's no doubt that we learn most about debt from the balance sheet. But ultimately, every company can contain risks that exist outside of the balance sheet. Case in point: We've spotted 1 warning sign for Mercury Systems you should be aware of.
