We Think Southern (NYSE:SO) Is Taking Some Risk With Its Debt

Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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 The Southern Company (NYSE:SO) makes use of debt. But is this debt a concern to shareholders?

What Risk Does Debt Bring?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. 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 examine debt levels, we first consider both cash and debt levels, together.

What Is Southern's Debt?

As you can see below, at the end of March 2023, Southern had US$59.0b of debt, up from US$54.3b a year ago. Click the image for more detail. And it doesn't have much cash, so its net debt is about the same.

A Look At Southern's Liabilities

According to the last reported balance sheet, Southern had liabilities of US$13.9b due within 12 months, and liabilities of US$86.3b due beyond 12 months. Offsetting these obligations, it had cash of US$1.05b as well as receivables valued at US$3.40b due within 12 months. So it has liabilities totalling US$95.7b more than its cash and near-term receivables, combined.

Given this deficit is actually higher than the company's massive market capitalization of US$76.8b, we think shareholders really should watch Southern's debt levels, like a parent watching their child ride a bike for the first time. In the scenario where the company had to clean up its balance sheet quickly, it seems likely shareholders would suffer extensive 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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

Southern has a rather high debt to EBITDA ratio of 5.6 which suggests a meaningful debt load. However, its interest coverage of 2.8 is reasonably strong, which is a good sign. Looking on the bright side, Southern boosted its EBIT by a silky 56% in the last year. 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 ultimately the future profitability of the business will decide if Southern 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.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs 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, Southern 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 Southern's net debt to EBITDA and its track record of converting EBIT to free cash flow make us rather uncomfortable with its debt levels. But at least it's pretty decent at growing its EBIT; that's encouraging. It's also worth noting that Southern is in the Electric Utilities industry, which is often considered to be quite defensive. Overall, we think it's fair to say that Southern 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. 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.
