David Iben put it well when he said, 'Volatility is not a risk we care about. What we care about is avoiding the 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 Kaiser Aluminum Corporation (NASDAQ:KALU) makes use of debt. But the more important question is: how much risk is that debt creating?

When Is Debt A Problem?

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. 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. 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 Kaiser Aluminum's Debt?

The chart below, which you can click on for greater detail, shows that Kaiser Aluminum had US$1.04b in debt in March 2024; about the same as the year before. On the flip side, it has US$101.6m in cash leading to net debt of about US$938.7m.

How Strong Is Kaiser Aluminum's Balance Sheet?

According to the last reported balance sheet, Kaiser Aluminum had liabilities of US$384.7m due within 12 months, and liabilities of US$1.25b due beyond 12 months. Offsetting this, it had US$101.6m in cash and US$415.6m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$1.12b.

This deficit is considerable relative to its market capitalization of US$1.51b, so it does suggest shareholders should keep an eye on Kaiser Aluminum's use of debt. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.

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). 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 Kaiser Aluminum's net debt to EBITDA ratio of 4.3, we think its super-low interest cover of 2.4 times is a sign of high leverage. It seems that the business incurs large depreciation and amortisation charges, so maybe its debt load is heavier than it would first appear, since EBITDA is arguably a generous measure of earnings. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. However, it should be some comfort for shareholders to recall that Kaiser Aluminum actually grew its EBIT by a hefty 453%, over the last 12 months. If that earnings trend continues it will make its debt load much more manageable in the future. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Kaiser Aluminum's ability to maintain a healthy balance sheet going forward.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the last three years, Kaiser Aluminum saw substantial negative free cash flow, in total. While investors are no doubt expecting a reversal of that situation in due course, it clearly does mean its use of debt is more risky.

Our View

Mulling over Kaiser Aluminum's attempt at converting EBIT to free cash flow, we're certainly not enthusiastic. But at least it's pretty decent at growing its EBIT; that's encouraging. Looking at the balance sheet and taking into account all these factors, we do believe that debt is making Kaiser Aluminum stock a bit risky. Some people like that sort of risk, but we're mindful of the potential pitfalls, so we'd probably prefer it carry less debt. 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.
