Is Sterlite Technologies (NSE:STLTECH) Using Too Much Debt?

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.' 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. Importantly, Sterlite Technologies Limited (NSE:STLTECH) does carry debt. But the real question is whether this debt is making the company risky.

When Is Debt A Problem?

Debt assists a business until the business has trouble paying it off, either with new capital or with free 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. 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. The first step when considering a company's debt levels is to consider its cash and debt together.

How Much Debt Does Sterlite Technologies Carry?

As you can see below, Sterlite Technologies had ₹19.3b of debt at March 2025, down from ₹33.8b a year prior. However, because it has a cash reserve of ₹4.68b, its net debt is less, at about ₹14.6b.

A Look At Sterlite Technologies' Liabilities

Zooming in on the latest balance sheet data, we can see that Sterlite Technologies had liabilities of ₹25.1b due within 12 months and liabilities of ₹10.3b due beyond that. Offsetting this, it had ₹4.68b in cash and ₹9.23b in receivables that were due within 12 months. So its liabilities total ₹21.5b more than the combination of its cash and short-term receivables.

This deficit isn't so bad because Sterlite Technologies is worth ₹55.3b, and thus could probably raise enough capital to shore up 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.

Check out our latest analysis for Sterlite Technologies

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 Sterlite Technologies's debt to EBITDA ratio (2.8) suggests that it uses some debt, its interest cover is very weak, at 0.72, suggesting high leverage. In large part that's due to the company's significant depreciation and amortisation charges, which arguably mean its EBITDA is a very generous measure of earnings, and its debt may be more of a burden than it first appears. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. The good news is that Sterlite Technologies grew its EBIT a smooth 43% over the last twelve months. Like a mother's loving embrace of a newborn that sort of growth builds resilience, putting the company in a stronger position to manage its debt. 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 Sterlite Technologies can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we always check how much of that EBIT is translated into free cash flow. During the last three years, Sterlite Technologies produced sturdy free cash flow equating to 72% of its EBIT, about what we'd expect. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

The good news is that Sterlite Technologies's demonstrated ability to grow its EBIT delights us like a fluffy puppy does a toddler. But we must concede we find its interest cover has the opposite effect. Looking at all the aforementioned factors together, it strikes us that Sterlite Technologies can handle its debt fairly comfortably. On the plus side, this leverage can boost shareholder returns, but the potential downside is more risk of loss, so it's worth monitoring the balance sheet. 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. These risks can be hard to spot. Every company has them, and we've spotted 2 warning signs for Sterlite Technologies (of which 1 is a bit unpleasant!) you should know about.

When all is said and done, sometimes its easier to focus on companies that don't even need debt. Readers can access a list of growth stocks with zero net debt 100% free, right now.
