Ultralife (NASDAQ:ULBI) Has A Pretty Healthy Balance Sheet

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. We can see that Ultralife Corporation (NASDAQ:ULBI) does use debt in its business. But is this debt a concern to shareholders?

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. If things get really bad, the lenders can take control of the business. 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, debt can be an important tool in businesses, particularly capital heavy businesses. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Ultralife's Net Debt?

You can click the graphic below for the historical numbers, but it shows that as of June 2019 Ultralife had US$15.8m of debt, an increase on none, over one year. However, it also had US$6.82m in cash, and so its net debt is US$8.97m.

A Look At Ultralife's Liabilities

According to the last reported balance sheet, Ultralife had liabilities of US$20.3m due within 12 months, and liabilities of US$15.4m due beyond 12 months. Offsetting this, it had US$6.82m in cash and US$25.1m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$3.75m.

Since publicly traded Ultralife shares are worth a total of US$137.9m, it seems unlikely that this level of liabilities would be a major threat. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse.

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).

Ultralife's net debt is only 1.1 times its EBITDA. And its EBIT covers its interest expense a whopping 48.1 times over. So we're pretty relaxed about its super-conservative use of debt. On the other hand, Ultralife's EBIT dived 16%, over the last year. If that rate of decline in earnings continues, the company could find itself in a tight spot. When analysing debt levels, the balance sheet is the obvious place to start. But it is Ultralife's earnings that will influence how the balance sheet holds up in the future. So when considering debt, it's definitely worth looking at the earnings trend. Click here for an interactive snapshot.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Over the most recent three years, Ultralife recorded free cash flow worth 65% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

Happily, Ultralife's impressive interest cover implies it has the upper hand on its debt. But the stark truth is that we are concerned by its EBIT growth rate. All these things considered, it appears that Ultralife can comfortably handle its current debt levels. 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.
