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.' 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. Importantly, China Southern Power Grid Energy Storage Co., Ltd. (SHSE:600995) does carry debt. But is this debt a concern to shareholders?

When Is Debt Dangerous?

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. 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. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. When we examine debt levels, we first consider both cash and debt levels, together.

What Is China Southern Power Grid Energy Storage's Debt?

The image below, which you can click on for greater detail, shows that at March 2024 China Southern Power Grid Energy Storage had debt of CN¥16.0b, up from CN¥11.1b in one year. However, it does have CN¥3.70b in cash offsetting this, leading to net debt of about CN¥12.3b.

A Look At China Southern Power Grid Energy Storage's Liabilities

According to the last reported balance sheet, China Southern Power Grid Energy Storage had liabilities of CN¥2.19b due within 12 months, and liabilities of CN¥18.7b due beyond 12 months. On the other hand, it had cash of CN¥3.70b and CN¥598.0m worth of receivables due within a year. So it has liabilities totalling CN¥16.6b more than its cash and near-term receivables, combined.

This deficit isn't so bad because China Southern Power Grid Energy Storage is worth CN¥30.8b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But it's clear that we should definitely closely examine whether it can manage its debt without 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.

China Southern Power Grid Energy Storage's debt is 3.6 times its EBITDA, and its EBIT cover its interest expense 4.1 times over. Taken together this implies that, while we wouldn't want to see debt levels rise, we think it can handle its current leverage. Worse, China Southern Power Grid Energy Storage's EBIT was down 42% over the last year. If earnings continue to follow that trajectory, paying off that debt load will be harder than convincing us to run a marathon in the rain. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if China Southern Power Grid Energy Storage 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. During the last three years, China Southern Power Grid Energy Storage burned a lot of cash. 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

On the face of it, China Southern Power Grid Energy Storage's conversion of EBIT to free cash flow left us tentative about the stock, and its EBIT growth rate was no more enticing than the one empty restaurant on the busiest night of the year. But at least its level of total liabilities is not so bad. It's also worth noting that China Southern Power Grid Energy Storage is in the Electric Utilities industry, which is often considered to be quite defensive. We're quite clear that we consider China Southern Power Grid Energy Storage to be really rather risky, as a result of its balance sheet health. For this reason we're pretty cautious about the stock, and we think shareholders should keep a close eye on its liquidity. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it. These risks can be hard to spot.
