Kaiser Aluminum (NASDAQ:KALU) Takes On Some Risk With Its Use Of Debt

The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' So it seems the smart money knows that debt - which is usually involved in bankruptcies - is a very important factor, when you assess how risky a company is. We note that Kaiser Aluminum Corporation (NASDAQ:KALU) does have debt on its balance sheet. But the real question is whether this debt is making the company risky.

Why Does Debt Bring Risk?

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. If things get really bad, the lenders can take control of the business. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Of course, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. When we think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does Kaiser Aluminum Carry?

The chart below, which you can click on for greater detail, shows that Kaiser Aluminum had US$1.04b in debt in September 2024; about the same as the year before. However, because it has a cash reserve of US$45.7m, its net debt is less, at about US$995.5m.

A Look At Kaiser Aluminum's Liabilities

According to the last reported balance sheet, Kaiser Aluminum had liabilities of US$382.2m due within 12 months, and liabilities of US$1.26b due beyond 12 months. Offsetting this, it had US$45.7m in cash and US$433.1m in receivables that were due within 12 months. So its liabilities total US$1.17b more than the combination of its cash and short-term receivables.

This deficit is considerable relative to its market capitalization of US$1.26b, so it does suggest shareholders should keep an eye on Kaiser Aluminum's use of debt. Should its lenders demand that it shore up the balance sheet, shareholders would likely face severe dilution.

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).

While Kaiser Aluminum's debt to EBITDA ratio (4.8) suggests that it uses some debt, its interest cover is very weak, at 2.2, suggesting high leverage. In large part that's due to the company's significant depreciation and amortisation charges, which arguably mean its EBITDA is a very generous measure of earnings, and its debt may be more of a burden than it first appears. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. On a lighter note, we note that Kaiser Aluminum grew its EBIT by 26% in the last year. If sustained, this growth should make that debt evaporate like a scarce drinking water during an unnaturally hot summer. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine Kaiser Aluminum's ability to maintain a healthy balance sheet going forward. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So we always check how much of that EBIT is translated into 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

To be frank both Kaiser Aluminum's interest cover and its track record of converting EBIT to free cash flow make us rather uncomfortable with its debt levels. But on the bright side, its EBIT growth rate is a good sign, and makes us more optimistic. Looking at the bigger picture, it seems clear to us that Kaiser Aluminum's use of debt is creating risks for the company. If all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. 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.
