The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' 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 MOS House Group Limited (HKG:1653) makes use of debt. But should shareholders be worried about its use of debt?
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. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.
As you can see below, MOS House Group had HK$92.7m of debt, at September 2025, which is about the same as the year before. You can click the chart for greater detail. However, it does have HK$61.7m in cash offsetting this, leading to net debt of about HK$31.0m.
Zooming in on the latest balance sheet data, we can see that MOS House Group had liabilities of HK$155.5m due within 12 months and liabilities of HK$34.9m due beyond that. Offsetting these obligations, it had cash of HK$61.7m as well as receivables valued at HK$103.7m due within 12 months. So its liabilities total HK$25.1m more than the combination of its cash and short-term receivables.
Since publicly traded MOS House Group shares are worth a total of HK$829.2m, it seems unlikely that this level of liabilities would be a major threat. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward.

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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.
While we wouldn't worry about MOS House Group's net debt to EBITDA ratio of 2.7, we think its super-low interest cover of 1.7 times is a sign of high leverage. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. However, the silver lining was that MOS House Group achieved a positive EBIT of HK$10m in the last twelve months, an improvement on the prior year's loss. There's no doubt that we learn most about debt from the balance sheet. But you can't view debt in total isolation; since MOS House Group will need earnings to service that debt. So if you're keen to discover more about its earnings, it might be worth checking out this graph of its long term earnings trend.
But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So it is important to check how much of its earnings before interest and tax (EBIT) converts to actual free cash flow. Over the last year, MOS House Group 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.
While MOS House Group's interest cover makes us cautious about it, its track record of converting EBIT to free cash flow is no better. But its not so bad at staying on top of its total liabilities. When we consider all the factors discussed, it seems to us that MOS House Group is taking some risks with its use of debt. So while that leverage does boost returns on equity, we wouldn't really want to see it increase from here. 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. For instance, we've identified 2 warning signs for MOS House Group that you should be aware of.
