Here's Why Kaiser Aluminum (NASDAQ:KALU) Can Manage Its Debt Responsibly

Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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 can see that Kaiser Aluminum Corporation (NASDAQ:KALU) does use debt in its business. But the real question is whether this debt is making the company risky.

Why Does Debt Bring Risk?

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. 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. When we examine debt levels, we first consider both cash and debt levels, 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 June 2022; about the same as the year before. On the flip side, it has US$235.2m in cash leading to net debt of about US$802.0m.

How Healthy Is Kaiser Aluminum's Balance Sheet?

According to the last reported balance sheet, Kaiser Aluminum had liabilities of US$547.5m due within 12 months, and liabilities of US$1.26b due beyond 12 months. Offsetting these obligations, it had cash of US$235.2m as well as receivables valued at US$494.5m due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$1.08b.

Given this deficit is actually higher than the company's market capitalization of US$984.2m, we think shareholders really should watch Kaiser Aluminum's debt levels, like a parent watching their child ride a bike for the first time. Hypothetically, extremely heavy dilution would be required if the company were forced to pay down its liabilities by raising capital at the current share price.

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 (4.2) suggests that it uses some debt, its interest cover is very weak, at 1.8, 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. Looking on the bright side, Kaiser Aluminum boosted its EBIT by a silky 54% in the last year. Like the milk of human kindness that sort of growth increases resilience, making the company more capable of managing 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 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 it's worth checking how much of that EBIT is backed by free cash flow. During the last three years, Kaiser Aluminum generated free cash flow amounting to a very robust 98% of its EBIT, more than we'd expect. That puts it in a very strong position to pay down debt.

Our View

Kaiser Aluminum's conversion of EBIT to free cash flow was a real positive on this analysis, as was its EBIT growth rate. In contrast, our confidence was undermined by its apparent struggle to cover its interest expense with its EBIT. When we consider all the factors mentioned above, we do feel a bit cautious about Kaiser Aluminum's use of debt. While we appreciate debt can enhance returns on equity, we'd suggest that shareholders keep close watch on its debt levels, lest they increase. 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.
