Legendary fund manager Li Lu (who Charlie Munger backed) once said, 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' 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. As with many other companies Nagahori Corporation (TSE:8139) makes use of debt. But the more important question is: how much risk is that debt creating?
Debt assists a business until the business has trouble paying it off, either with new capital or with free 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 common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. Of course, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest 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.
You can click the graphic below for the historical numbers, but it shows that as of September 2025 Nagahori had JP¥12.2b of debt, an increase on JP¥10.1b, over one year. On the flip side, it has JP¥2.17b in cash leading to net debt of about JP¥10.1b.
According to the last reported balance sheet, Nagahori had liabilities of JP¥13.9b due within 12 months, and liabilities of JP¥1.53b due beyond 12 months. Offsetting this, it had JP¥2.17b in cash and JP¥3.44b in receivables that were due within 12 months. So its liabilities total JP¥9.84b more than the combination of its cash and short-term receivables.
While this might seem like a lot, it is not so bad since Nagahori has a market capitalization of JP¥32.6b, and so it could probably strengthen its balance sheet by raising capital if it needed to. However, it is still worthwhile taking a close look at its ability to pay off debt.
Check out our latest analysis for Nagahori
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). The advantage of this approach is that we take into account both the absolute quantum of debt (with net debt to EBITDA) and the actual interest expenses associated with that debt (with its interest cover ratio).
While Nagahori's debt to EBITDA ratio of 9.8 suggests a heavy debt load, its interest coverage of 7.8 implies it services that debt with ease. Overall we'd say it seems likely the company is carrying a fairly heavy swag of debt. The bad news is that Nagahori saw its EBIT decline by 11% over the last year. If earnings continue to decline at that rate then handling the debt will be more difficult than taking three children under 5 to a fancy pants restaurant. There's no doubt that we learn most about debt from the balance sheet. But it is Nagahori's earnings that will influence how the balance sheet holds up in the future. So if you're keen to discover more about its earnings, it might be worth checking out this graph of its long term earnings trend.
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. Over the last three years, Nagahori saw substantial negative free cash flow, in total. While investors are no doubt expecting a reversal of that situation in due course, it clearly does mean its use of debt is more risky.
To be frank both Nagahori's net debt to EBITDA and its track record of converting EBIT to free cash flow make us rather uncomfortable with its debt levels. But at least it's pretty decent at covering its interest expense with its EBIT; that's encouraging. Looking at the bigger picture, it seems clear to us that Nagahori's use of debt is creating risks for the company. If all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. 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.
