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.' 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. As with many other companies Freightways Group Limited (NZSE:FRW) makes use of debt. But should shareholders be worried about its use of debt?

When Is Debt Dangerous?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. 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. Of course, plenty of companies use debt to fund growth, without any negative consequences. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is Freightways Group's Net Debt?

As you can see below, Freightways Group had NZ$265.7m of debt at June 2024, down from NZ$297.2m a year prior. On the flip side, it has NZ$36.1m in cash leading to net debt of about NZ$229.5m.

A Look At Freightways Group's Liabilities

The latest balance sheet data shows that Freightways Group had liabilities of NZ$238.9m due within a year, and liabilities of NZ$662.9m falling due after that. Offsetting this, it had NZ$36.1m in cash and NZ$162.1m in receivables that were due within 12 months. So its liabilities total NZ$703.5m more than the combination of its cash and short-term receivables.

While this might seem like a lot, it is not so bad since Freightways Group has a market capitalization of NZ$1.60b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.

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 Freightways Group's low debt to EBITDA ratio of 1.3 suggests only modest use of debt, the fact that EBIT only covered the interest expense by 3.9 times last year does give us pause. But the interest payments are certainly sufficient to have us thinking about how affordable its debt is. Importantly Freightways Group's EBIT was essentially flat over the last twelve months. We would prefer to see some earnings growth, because that always helps diminish 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 Freightways Group'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.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. During the last three years, Freightways Group generated free cash flow amounting to a very robust 87% of its EBIT, more than we'd expect. That positions it well to pay down debt if desirable to do so.

Our View

On our analysis Freightways Group's conversion of EBIT to free cash flow should signal that it won't have too much trouble with its debt. However, our other observations weren't so heartening. For example, its interest cover makes us a little nervous about its debt. When we consider all the elements mentioned above, it seems to us that Freightways Group is managing its debt quite well. Having said that, the load is sufficiently heavy that we would recommend any shareholders keep a close eye on it. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it. For example - Freightways Group has 2 warning signs we think you should be aware of.
