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. We can see that PPG Industries, Inc. (NYSE:PPG) does use debt in its business. But is this debt a concern to shareholders?
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. 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 thing to do when considering how much debt a business uses is to look at its cash and debt together.
The image below, which you can click on for greater detail, shows that at September 2025 PPG Industries had debt of US$7.31b, up from US$6.48b in one year. However, because it has a cash reserve of US$1.92b, its net debt is less, at about US$5.40b.
The latest balance sheet data shows that PPG Industries had liabilities of US$5.61b due within a year, and liabilities of US$8.58b falling due after that. Offsetting this, it had US$1.92b in cash and US$3.72b in receivables that were due within 12 months. So it has liabilities totalling US$8.55b more than its cash and near-term receivables, combined.
PPG Industries has a very large market capitalization of US$23.4b, so it could very likely raise cash to ameliorate its balance sheet, if the need arose. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.

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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.
PPG Industries's net debt to EBITDA ratio of about 2.0 suggests only moderate use of debt. And its strong interest cover of 30.8 times, makes us even more comfortable. Sadly, PPG Industries's EBIT actually dropped 2.6% in the last year. If earnings continue on that decline then managing that debt will be difficult like delivering hot soup on a unicycle. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine PPG Industries's ability to maintain a healthy balance sheet going forward. So if you're focused on the future you can check out this free report showing analyst profit forecasts.
Finally, a company can only pay off debt with cold hard cash, not accounting profits. So we always check how much of that EBIT is translated into free cash flow. During the last three years, PPG Industries produced sturdy free cash flow equating to 56% of its EBIT, about what we'd expect. This cold hard cash means it can reduce its debt when it wants to.
When it comes to the balance sheet, the standout positive for PPG Industries was the fact that it seems able to cover its interest expense with its EBIT confidently. But the other factors we noted above weren't so encouraging. For example, its EBIT growth rate makes us a little nervous about its debt. Considering this range of data points, we think PPG Industries is in a good position to manage its debt levels. But a word of caution: we think debt levels are high enough to justify ongoing monitoring. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately, every company can contain risks that exist outside of the balance sheet. To that end, you should be aware of the 1 warning sign we've spotted with PPG Industries .
At the end of the day, it's often better to focus on companies that are free from net debt. You can access our special list of such companies (all with a track record of profit growth). It's free.
