Warren Buffett famously said, '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 Furukawa Electric Co., Ltd. (TSE:5801) does use debt in its business. But is this debt a concern to shareholders?
Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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, debt can be an important tool in businesses, particularly capital heavy businesses. The first step when considering a company's debt levels is to consider its cash and debt together.
The chart below, which you can click on for greater detail, shows that Furukawa Electric had JP¥341.8b in debt in September 2025; about the same as the year before. However, because it has a cash reserve of JP¥73.6b, its net debt is less, at about JP¥268.2b.
The latest balance sheet data shows that Furukawa Electric had liabilities of JP¥437.7b due within a year, and liabilities of JP¥209.3b falling due after that. Offsetting these obligations, it had cash of JP¥73.6b as well as receivables valued at JP¥261.3b due within 12 months. So it has liabilities totalling JP¥312.0b more than its cash and near-term receivables, combined.
Furukawa Electric has a market capitalization of JP¥741.5b, 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.
Check out our latest analysis for Furukawa Electric
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.
Furukawa Electric has net debt to EBITDA of 3.0 suggesting it uses a fair bit of leverage to boost returns. But the high interest coverage of 9.0 suggests it can easily service that debt. Importantly, Furukawa Electric grew its EBIT by 47% over the last twelve months, and that growth will make it easier to handle its 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 Furukawa Electric'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.
But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So we always check how much of that EBIT is translated into free cash flow. Over the last three years, Furukawa Electric recorded negative free cash flow, in total. Debt is usually more expensive, and almost always more risky in the hands of a company with negative free cash flow. Shareholders ought to hope for an improvement.
On our analysis Furukawa Electric's EBIT growth rate should signal that it won't have too much trouble with its debt. However, our other observations weren't so heartening. To be specific, it seems about as good at converting EBIT to free cash flow as wet socks are at keeping your feet warm. Looking at all this data makes us feel a little cautious about Furukawa Electric's debt levels. While we appreciate debt can enhance returns on equity, we'd suggest that shareholders keep close watch on its debt levels, lest they increase. 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.
