Is L.B. Foster (NASDAQ:FSTR) A Risky Investment?

Simply Wall St

Warren Buffett famously said, 'Volatility is far from synonymous with risk.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. We can see that L.B. Foster Company (NASDAQ:FSTR) does use debt in its business. But is this debt a concern to shareholders?

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. 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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. When we examine debt levels, we first consider both cash and debt levels, together.

How Strong Is L.B. Foster's Balance Sheet?

We can see from the most recent balance sheet that L.B. Foster had liabilities of US$123.6m falling due within a year, and liabilities of US$157.0m due beyond that. Offsetting this, it had US$12.0m in cash and US$98.7m in receivables that were due within 12 months. So its liabilities total US$169.9m more than the combination of its cash and short-term receivables.

This is a mountain of leverage relative to its market capitalization of US$212.3m. This suggests shareholders would heavily diluted if the company needed to shore up its balance sheet in a hurry.

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).

L.B. Foster has net debt worth 1.5 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 5.8 times the interest expense. While these numbers do not alarm us, it's worth noting that the cost of the company's debt is having a real impact. Importantly, L.B. Foster grew its EBIT by 64% over the last twelve months, and that growth will make it easier to handle its debt. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine L.B. Foster's ability to maintain a healthy balance sheet going forward. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

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. During the last three years, L.B. Foster generated free cash flow amounting to a very robust 90% of its EBIT, more than we'd expect. That puts it in a very strong position to pay down debt.

Our View

L.B. Foster's conversion of EBIT to free cash flow suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. But, on a more sombre note, we are a little concerned by its level of total liabilities. All these things considered, it appears that L.B. Foster 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. Even though L.B. Foster lost money on the bottom line, its positive EBIT suggests the business itself has potential. So you might want to check outhow earnings have been trending over the last few years.
