These 4 Measures Indicate That Corning (NYSE:GLW) Is Using Debt Reasonably Well

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. Importantly, Corning Incorporated (NYSE:GLW) does carry debt. But should shareholders be worried about its use of debt?

What Risk Does Debt Bring?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. 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 thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is Corning's Debt?

As you can see below, Corning had US$7.21b of debt, at December 2024, which is about the same as the year before. You can click the chart for greater detail. On the flip side, it has US$1.77b in cash leading to net debt of about US$5.44b.

A Look At Corning's Liabilities

Zooming in on the latest balance sheet data, we can see that Corning had liabilities of US$4.92b due within 12 months and liabilities of US$11.7b due beyond that. Offsetting this, it had US$1.77b in cash and US$2.05b in receivables that were due within 12 months. So it has liabilities totalling US$12.8b more than its cash and near-term receivables, combined.

This deficit isn't so bad because Corning is worth a massive US$42.3b, 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.

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.

Corning has net debt worth 2.0 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 4.9 times the interest expense. While these numbers do not alarm us, it's worth noting that the cost of the company's debt is having a real impact. Corning grew its EBIT by 3.7% in the last year. Whilst that hardly knocks our socks off it is a positive when it comes to debt. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Corning'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.

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 most recent three years, Corning recorded free cash flow worth 56% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

Both Corning's ability to to convert EBIT to free cash flow and its EBIT growth rate gave us comfort that it can handle its debt. Having said that, its interest cover somewhat sensitizes us to potential future risks to the balance sheet. Looking at all this data makes us feel a little cautious about Corning's debt levels. While debt does have its upside in higher potential returns, we think shareholders should definitely consider how debt levels might make the stock more risky. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it. For example Corning has 4 warning signs (and 1 which doesn't sit too well with us) we think you should know about.
