Some say volatility, rather than debt, is the best way to think about risk as an investor, but Warren Buffett famously said that '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 note that Vianet Group plc (LON:VNET) does have debt on its balance sheet. But should shareholders be worried about its use of debt?
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 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, plenty of companies use debt to fund growth, without any negative consequences. 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 Vianet Group had debt of UK£3.06m at the end of September 2025, a reduction from UK£3.25m over a year. On the flip side, it has UK£2.57m in cash leading to net debt of about UK£493.0k.
According to the last reported balance sheet, Vianet Group had liabilities of UK£2.88m due within 12 months, and liabilities of UK£3.99m due beyond 12 months. Offsetting this, it had UK£2.57m in cash and UK£3.61m in receivables that were due within 12 months. So it has liabilities totalling UK£690.0k more than its cash and near-term receivables, combined.
Given Vianet Group has a market capitalization of UK£20.8m, it's hard to believe these liabilities pose much threat. However, we do think it is worth keeping an eye on its balance sheet strength, as it may change over time.
Check out our latest analysis for Vianet Group
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). 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).
Looking at its net debt to EBITDA of 0.27 and interest cover of 4.8 times, it seems to us that Vianet Group is probably using debt in a pretty reasonable way. But the interest payments are certainly sufficient to have us thinking about how affordable its debt is. One way Vianet Group could vanquish its debt would be if it stops borrowing more but continues to grow EBIT at around 12%, as it did over the last year. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Vianet Group's ability to maintain a healthy balance sheet going forward. 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 always check how much of that EBIT is translated into free cash flow. Over the last three years, Vianet Group actually produced more free cash flow than EBIT. That sort of strong cash generation warms our hearts like a puppy in a bumblebee suit.
The good news is that Vianet Group's demonstrated ability to convert EBIT to free cash flow delights us like a fluffy puppy does a toddler. And that's just the beginning of the good news since its net debt to EBITDA is also very heartening. Zooming out, Vianet Group seems to use debt quite reasonably; and that gets the nod from us. While debt does bring risk, when used wisely it can also bring a higher return on equity. 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. For example - Vianet Group has 1 warning sign we think you should be aware of.
