Warren Buffett famously said, 'Volatility is far from synonymous with risk.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We can see that James Hardie Industries plc (ASX:JHX) does use debt in its business. But the real question is whether this debt is making the company risky.
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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. However, a more common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. 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.
As you can see below, at the end of September 2025, James Hardie Industries had US$5.03b of debt, up from US$1.14b a year ago. Click the image for more detail. However, because it has a cash reserve of US$566.7m, its net debt is less, at about US$4.46b.
Zooming in on the latest balance sheet data, we can see that James Hardie Industries had liabilities of US$1.13b due within 12 months and liabilities of US$6.62b due beyond that. Offsetting this, it had US$566.7m in cash and US$365.5m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$6.81b.
This is a mountain of leverage even relative to its gargantuan market capitalization of US$11.1b. Should its lenders demand that it shore up the balance sheet, shareholders would likely face severe 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.
James Hardie Industries has net debt to EBITDA of 4.3 suggesting it uses a fair bit of leverage to boost returns. On the plus side, its EBIT was 8.5 times its interest expense, and its net debt to EBITDA, was quite high, at 4.3. The bad news is that James Hardie Industries saw its EBIT decline by 19% over the last year. If that sort of decline is not arrested, then the managing its debt will be harder than selling broccoli flavoured ice-cream for a premium. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine James Hardie Industries's ability to maintain a healthy balance sheet going forward.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. In the last three years, James Hardie Industries's free cash flow amounted to 37% of its EBIT, less than we'd expect. That weak cash conversion makes it more difficult to handle indebtedness.
Mulling over James Hardie Industries's attempt at (not) growing its EBIT, we're certainly not enthusiastic. But on the bright side, its interest cover is a good sign, and makes us more optimistic. Looking at the bigger picture, it seems clear to us that James Hardie Industries's use of debt is creating risks for the company. If everything goes well that may pay off but the downside of this debt is a greater risk of permanent losses. 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.
