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 can see that De Neers Tools Limited (NSE:DENEERS) does use debt in its business. But the real question is whether this debt is making the company risky.
When Is Debt A Problem?
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. If things get really bad, the lenders can take control of the business. 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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. When we think about a company's use of debt, we first look at cash and debt together.
What Is De Neers Tools's Net Debt?
You can click the graphic below for the historical numbers, but it shows that as of September 2025 De Neers Tools had ₹635.2m of debt, an increase on ₹537.2m, over one year. And it doesn't have much cash, so its net debt is about the same.
A Look At De Neers Tools' Liabilities
Zooming in on the latest balance sheet data, we can see that De Neers Tools had liabilities of ₹746.5m due within 12 months and liabilities of ₹331.5m due beyond that. On the other hand, it had cash of ₹7.68m and ₹459.7m worth of receivables due within a year. So it has liabilities totalling ₹610.6m more than its cash and near-term receivables, combined.
While this might seem like a lot, it is not so bad since De Neers Tools has a market capitalization of ₹1.18b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.
See our latest analysis for De Neers Tools
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).
De Neers Tools's net debt is sitting at a very reasonable 2.4 times its EBITDA, while its EBIT covered its interest expense just 6.7 times last year. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. Also relevant is that De Neers Tools has grown its EBIT by a very respectable 26% in the last year, thus enhancing its ability to pay down debt. When analysing debt levels, the balance sheet is the obvious place to start. But it is De Neers Tools's earnings that will influence how the balance sheet holds up in the future. So when considering debt, it's definitely worth looking at the earnings trend. Click here for an interactive snapshot.
Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. Over the last three years, De Neers Tools 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.
Our View
De Neers Tools's conversion of EBIT to free cash flow was a real negative on this analysis, although the other factors we considered cast it in a significantly better light. For example its EBIT growth rate was refreshing. Looking at all the angles mentioned above, it does seem to us that De Neers Tools 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. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately, every company can contain risks that exist outside of the balance sheet.
