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

When Is Debt A Problem?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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 think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does Comms Group Carry?

You can click the graphic below for the historical numbers, but it shows that Comms Group had AU$7.00m of debt in December 2024, down from AU$8.13m, one year before. However, because it has a cash reserve of AU$2.72m, its net debt is less, at about AU$4.28m.

How Healthy Is Comms Group's Balance Sheet?

We can see from the most recent balance sheet that Comms Group had liabilities of AU$10.9m falling due within a year, and liabilities of AU$14.2m due beyond that. Offsetting these obligations, it had cash of AU$2.72m as well as receivables valued at AU$5.87m due within 12 months. So it has liabilities totalling AU$16.5m more than its cash and near-term receivables, combined.

This deficit is considerable relative to its market capitalization of AU$23.0m, so it does suggest shareholders should keep an eye on Comms Group's use of debt. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.

In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its 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).

Even though Comms Group's debt is only 1.7, its interest cover is really very low at 0.91. The main reason for this is that it has such high depreciation and amortisation. While companies often boast that these charges are non-cash, most such businesses will therefore require ongoing investment (that is not expensed.) In any case, it's safe to say the company has meaningful debt. We also note that Comms Group improved its EBIT from a last year's loss to a positive AU$755k. The balance sheet is clearly the area to focus on when you are analysing debt. But it is Comms Group'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 it is important to check how much of its earnings before interest and tax (EBIT) converts to actual free cash flow. Happily for any shareholders, Comms Group actually produced more free cash flow than EBIT over the last year. That sort of strong cash generation warms our hearts like a puppy in a bumblebee suit.

Our View

Comms Group's interest cover and level of total liabilities definitely weigh on it, in our esteem. But its conversion of EBIT to free cash flow tells a very different story, and suggests some resilience. Looking at all the angles mentioned above, it does seem to us that Comms Group is a somewhat risky investment as a result of its debt. That's not necessarily a bad thing, since leverage can boost returns on equity, but it is something to be aware of. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately, every company can contain risks that exist outside of the balance sheet. We've identified 2 warning signs with Comms Group , and understanding them should be part of your investment process.
