Is Atlantica Sustainable Infrastructure (NASDAQ:AY) Using Too Much 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 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. We note that Atlantica Sustainable Infrastructure plc (NASDAQ:AY) does have debt on its balance sheet. But should shareholders be worried about its use of debt?

When Is Debt A Problem?

Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. 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 examine debt levels, we first consider both cash and debt levels, together.

How Much Debt Does Atlantica Sustainable Infrastructure Carry?

As you can see below, Atlantica Sustainable Infrastructure had US$5.50b of debt at June 2023, down from US$5.82b a year prior. However, because it has a cash reserve of US$658.9m, its net debt is less, at about US$4.84b.

How Healthy Is Atlantica Sustainable Infrastructure's Balance Sheet?

The latest balance sheet data shows that Atlantica Sustainable Infrastructure had liabilities of US$532.5m due within a year, and liabilities of US$6.66b falling due after that. Offsetting this, it had US$658.9m in cash and US$262.6m in receivables that were due within 12 months. So it has liabilities totalling US$6.27b more than its cash and near-term receivables, combined.

The deficiency here weighs heavily on the US$2.41b 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, Atlantica Sustainable Infrastructure would likely require a major re-capitalisation if it had to pay its creditors today.

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

Weak interest cover of 0.81 times and a disturbingly high net debt to EBITDA ratio of 7.1 hit our confidence in Atlantica Sustainable Infrastructure like a one-two punch to the gut. This means we'd consider it to have a heavy debt load. The good news is that Atlantica Sustainable Infrastructure improved its EBIT by 3.4% over the last twelve months, thus gradually reducing its debt levels relative to its earnings. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Atlantica Sustainable Infrastructure can strengthen its balance sheet over time. 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 clearly need to look at whether that EBIT is leading to corresponding free cash flow. Over the last three years, Atlantica Sustainable Infrastructure actually produced more free cash flow than EBIT. That sort of strong cash generation warms our hearts like a puppy in a bumblebee suit.

Our View

On the face of it, Atlantica Sustainable Infrastructure's interest cover left us tentative about the stock, and its level of total liabilities was no more enticing than the one empty restaurant on the busiest night of the year. But at least it's pretty decent at converting EBIT to free cash flow; that's encouraging. Overall, we think it's fair to say that Atlantica Sustainable Infrastructure has enough debt that there are some real risks around the balance sheet. If everything goes well that may pay off but the downside of this debt is a greater risk of permanent losses. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet. These risks can be hard to spot. Every company has them, and we've spotted 3 warning signs for Atlantica Sustainable Infrastructure (of which 1 is a bit concerning!) you should know about.
