Legendary fund manager Li Lu (who Charlie Munger backed) once said, '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 Guangdong Investment Limited (HKG:270) does have debt on its balance sheet. But the real question is whether this debt is making the company risky.
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. If things get really bad, the lenders can take control of the business. However, a more common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. 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. The first step when considering a company's debt levels is to consider its cash and debt together.
The image below, which you can click on for greater detail, shows that Guangdong Investment had debt of HK$21.9b at the end of June 2025, a reduction from HK$42.7b over a year. On the flip side, it has HK$12.0b in cash leading to net debt of about HK$9.89b.
Zooming in on the latest balance sheet data, we can see that Guangdong Investment had liabilities of HK$18.0b due within 12 months and liabilities of HK$23.3b due beyond that. On the other hand, it had cash of HK$12.0b and HK$8.58b worth of receivables due within a year. So it has liabilities totalling HK$20.6b more than its cash and near-term receivables, combined.
Guangdong Investment has a market capitalization of HK$44.6b, so it could very likely raise cash to ameliorate its balance sheet, if the need arose. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.

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). 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).
Guangdong Investment's net debt is only 1.0 times its EBITDA. And its EBIT easily covers its interest expense, being 24.2 times the size. So we're pretty relaxed about its super-conservative use of debt. On top of that, Guangdong Investment grew its EBIT by 46% over the last twelve months, and that growth will make it easier to handle its debt. 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 Guangdong Investment can strengthen its balance sheet over time. So if you're focused on the future you can check out this free report showing analyst profit forecasts.
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, Guangdong Investment 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.
The good news is that Guangdong Investment's demonstrated ability to cover its interest expense with its EBIT delights us like a fluffy puppy does a toddler. But truth be told we feel its level of total liabilities does undermine this impression a bit. We would also note that Water Utilities industry companies like Guangdong Investment commonly do use debt without problems. Looking at the bigger picture, we think Guangdong Investment's use of debt seems quite reasonable and we're not concerned about it. While debt does bring risk, when used wisely it can also bring a higher return on equity. 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. To that end, you should be aware of the 1 warning sign we've spotted with Guangdong Investment .
