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. Importantly, Motorcar Parts of America, Inc. (NASDAQ:MPAA) does carry debt. But is this debt a concern to shareholders?

What Risk Does Debt Bring?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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 Motorcar Parts of America's Net Debt?

As you can see below, Motorcar Parts of America had US$183.5m of debt at September 2024, down from US$196.8m a year prior. On the flip side, it has US$12.3m in cash leading to net debt of about US$171.2m.

How Healthy Is Motorcar Parts of America's Balance Sheet?

We can see from the most recent balance sheet that Motorcar Parts of America had liabilities of US$393.9m falling due within a year, and liabilities of US$328.3m due beyond that. On the other hand, it had cash of US$12.3m and US$137.7m worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$572.3m.

The deficiency here weighs heavily on the US$124.3m company itself, as if a child were struggling under the weight of an enormous back-pack full of books, his sports gear, and a trumpet. So we'd watch its balance sheet closely, without a doubt. After all, Motorcar Parts of America would likely require a major re-capitalisation if it had to pay its creditors today.

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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

While we wouldn't worry about Motorcar Parts of America's net debt to EBITDA ratio of 3.4, we think its super-low interest cover of 0.65 times is a sign of high leverage. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. Even more troubling is the fact that Motorcar Parts of America actually let its EBIT decrease by 2.6% over the last year. If it keeps going like that paying off its debt will be like running on a treadmill -- a lot of effort for not much advancement. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Motorcar Parts of America'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. Considering the last three years, Motorcar Parts of America 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 Motorcar Parts of America's interest cover and its track record of staying on top of its total liabilities make us rather uncomfortable with its debt levels. Having said that, its ability to grow its EBIT isn't such a worry. Taking into account all the aforementioned factors, it looks like Motorcar Parts of America has too much debt. While some investors love that sort of risky play, it's certainly not our cup of tea. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it.
