We Think Corning (NYSE:GLW) Is Taking Some Risk With Its Debt

Some say volatility, rather than debt, is the best way to think about risk as an investor, but Warren Buffett famously said that 'Volatility is far from synonymous with risk.' 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 the more important question is: how much risk is that debt creating?

What Risk Does Debt Bring?

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. Of course, plenty of companies use debt to fund growth, without any negative consequences. The first step when considering a company's debt levels is to consider its cash and debt together.

How Much Debt Does Corning Carry?

The image below, which you can click on for greater detail, shows that at December 2023 Corning had debt of US$7.33b, up from US$6.72b in one year. On the flip side, it has US$1.78b in cash leading to net debt of about US$5.55b.

A Look At Corning's Liabilities

The latest balance sheet data shows that Corning had liabilities of US$4.32b due within a year, and liabilities of US$12.3b falling due after that. On the other hand, it had cash of US$1.78b and US$1.57b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$13.3b.

This deficit isn't so bad because Corning is worth a massive US$27.7b, 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.

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (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 2.1 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 4.5 times the interest expense. It seems that the business incurs large depreciation and amortisation charges, so maybe its debt load is heavier than it would first appear, since EBITDA is arguably a generous measure of earnings. Importantly, Corning's EBIT fell a jaw-dropping 30% in the last twelve months. If that earnings trend continues then paying off its debt will be about as easy as herding cats on to a roller coaster. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine Corning's ability to maintain a healthy balance sheet going forward.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the most recent three years, Corning recorded free cash flow worth 62% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This cold hard cash means it can reduce its debt when it wants to.

Our View

Corning's EBIT growth rate was a real negative on this analysis, although the other factors we considered cast it in a significantly better light. But on the bright side, its ability to to convert EBIT to free cash flow isn't too shabby at all. When we consider all the factors discussed, it seems to us that Corning 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. 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.

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.
