Warren Buffett famously said, 'Volatility is far from synonymous with risk.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We can see that MTR Corporation Limited (HKG:66) does use debt in its business. But the real question is whether this debt is making the company risky.
Why Does Debt Bring Risk?
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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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, plenty of companies use debt to fund growth, without any negative consequences. When we think about a company's use of debt, we first look at cash and debt together.
What Is MTR's Debt?
The image below, which you can click on for greater detail, shows that at December 2024 MTR had debt of HK$76.7b, up from HK$59.2b in one year. However, it does have HK$22.2b in cash offsetting this, leading to net debt of about HK$54.5b.
How Strong Is MTR's Balance Sheet?
We can see from the most recent balance sheet that MTR had liabilities of HK$30.3b falling due within a year, and liabilities of HK$151.0b due beyond that. Offsetting this, it had HK$22.2b in cash and HK$18.6b in receivables that were due within 12 months. So its liabilities total HK$140.5b more than the combination of its cash and short-term receivables.
This is a mountain of leverage even relative to its gargantuan market capitalization of HK$174.3b. Should its lenders demand that it shore up the balance sheet, shareholders would likely face severe dilution.
View our latest analysis for MTR
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).
We'd say that MTR's moderate net debt to EBITDA ratio ( being 2.0), indicates prudence when it comes to debt. And its commanding EBIT of 21.0 times its interest expense, implies the debt load is as light as a peacock feather. Pleasingly, MTR is growing its EBIT faster than former Australian PM Bob Hawke downs a yard glass, boasting a 128% gain in the last twelve months. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if MTR can strengthen its balance sheet over time.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, MTR saw substantial negative free cash flow, in total. While that may be a result of expenditure for growth, it does make the debt far more risky.

Our View
While MTR's conversion of EBIT to free cash flow has us nervous. For example, its interest cover and EBIT growth rate give us some confidence in its ability to manage its debt. Looking at all the angles mentioned above, it does seem to us that MTR is a somewhat risky investment as a result of its debt. That's not necessarily a bad thing, since leverage can boost returns on equity, but it is something to be aware of. There's no doubt that we learn most about debt from the balance sheet. However, not all investment risk resides within the balance sheet - far from it. These risks can be hard to spot. Every company has them, and we've spotted 2 warning signs for MTR (of which 1 is a bit concerning!) you should know about.
