Is Kaiser Aluminum (NASDAQ:KALU) Using Too Much Debt?

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.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. As with many other companies Kaiser Aluminum Corporation (NASDAQ:KALU) makes use of debt. But is this debt a concern to shareholders?

When Is Debt A Problem?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth at high rates of return. When we think about a company's use of debt, we first look at cash and debt together.

What Is Kaiser Aluminum's Debt?

You can click the graphic below for the historical numbers, but it shows that as of March 2022 Kaiser Aluminum had US$1.04b of debt, an increase on US$838.7m, over one year. On the flip side, it has US$261.0m in cash leading to net debt of about US$775.8m.

A Look At Kaiser Aluminum's Liabilities

The latest balance sheet data shows that Kaiser Aluminum had liabilities of US$554.6m due within a year, and liabilities of US$1.28b falling due after that. Offsetting this, it had US$261.0m in cash and US$557.7m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$1.01b.

This deficit is considerable relative to its market capitalization of US$1.47b, 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.

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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

While we wouldn't worry about Kaiser Aluminum's net debt to EBITDA ratio of 3.9, we think its super-low interest cover of 1.9 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. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. The good news is that Kaiser Aluminum grew its EBIT a smooth 57% over the last twelve months. Like a mother's loving embrace of a newborn that sort of growth builds resilience, putting the company in a stronger position to manage its debt. 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. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we always check how much of that EBIT is translated into free cash flow. Happily for any shareholders, Kaiser Aluminum actually produced more free cash flow than EBIT over the last three years. That sort of strong cash conversion gets us as excited as the crowd when the beat drops at a Daft Punk concert.

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. But truth be told its interest cover had us nibbling our nails. Considering this range of data points, we think Kaiser Aluminum is in a good position to manage its debt levels. Having said that, the load is sufficiently heavy that we would recommend any shareholders keep a close eye on it. There's no doubt that we learn most about debt from the balance sheet. But ultimately, every company can contain risks that exist outside of the balance sheet. Case in point: We've spotted 3 warning signs for Kaiser Aluminum you should be aware of, and 2 of them are potentially serious.
