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. We note that Greenlam Industries Limited (NSE:GREENLAM) does have debt on its balance sheet. But the more important question is: how much risk is that debt creating?
Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. If things get really bad, the lenders can take control of the business. 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. 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. When we think about a company's use of debt, we first look at cash and debt together.
The image below, which you can click on for greater detail, shows that Greenlam Industries had debt of ₹10.5b at the end of September 2025, a reduction from ₹11.1b over a year. However, it does have ₹669.3m in cash offsetting this, leading to net debt of about ₹9.84b.
According to the last reported balance sheet, Greenlam Industries had liabilities of ₹10.3b due within 12 months, and liabilities of ₹7.85b due beyond 12 months. On the other hand, it had cash of ₹669.3m and ₹2.16b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by ₹15.4b.
Greenlam Industries has a market capitalization of ₹67.8b, 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.
View our latest analysis for Greenlam Industries
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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.
While Greenlam Industries's debt to EBITDA ratio (3.9) suggests that it uses some debt, its interest cover is very weak, at 1.8, suggesting high leverage. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Even worse, Greenlam Industries saw its EBIT tank 27% over the last 12 months. If earnings continue to follow that trajectory, paying off that debt load will be harder than convincing us to run a marathon in the rain. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if Greenlam Industries can strengthen its balance sheet over time.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, Greenlam Industries 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.
To be frank both Greenlam Industries's conversion of EBIT to free cash flow and its track record of (not) growing its EBIT make us rather uncomfortable with its debt levels. Having said that, its ability to handle its total liabilities isn't such a worry. Overall, it seems to us that Greenlam Industries's balance sheet is really quite a risk to the business. So we're almost as wary of this stock as a hungry kitten is about falling into its owner's fish pond: once bitten, twice shy, as they say. 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 Greenlam Industries has 2 warning signs (and 1 which is significant) we think you should know about.
