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

David Iben put it well when he said, 'Volatility is not a risk we care about. What we care about is avoiding the 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, 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?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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. Of course, plenty of companies use debt to fund growth, without any negative consequences. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Corning's Net Debt?

You can click the graphic below for the historical numbers, but it shows that as of June 2023 Corning had US$7.62b of debt, an increase on US$6.80b, over one year. However, it also had US$1.54b in cash, and so its net debt is US$6.09b.

How Healthy Is Corning's Balance Sheet?

According to the last reported balance sheet, Corning had liabilities of US$4.41b due within 12 months, and liabilities of US$12.5b due beyond 12 months. Offsetting this, it had US$1.54b in cash and US$1.67b in receivables that were due within 12 months. So it has liabilities totalling US$13.7b more than its cash and near-term receivables, combined.

While this might seem like a lot, it is not so bad since Corning has a huge market capitalization of US$23.4b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.

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). 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 2.2 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 that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. Shareholders should be aware that Corning's EBIT was down 38% last year. 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 ultimately the future profitability of the business will decide if Corning 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, 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 59% 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

We'd go so far as to say Corning's EBIT growth rate was disappointing. But on the bright side, its conversion of EBIT to free cash flow is a good sign, and makes us more optimistic. Looking at the balance sheet and taking into account all these factors, we do believe that debt is making Corning stock a bit risky. That's not necessarily a bad thing, but we'd generally feel more comfortable with less leverage. 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. Case in point: We've spotted 5 warning signs for Corning you should be aware of, and 1 of them is significant.
