The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says '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. Importantly, OXIDE Corporation (TSE:6521) does carry debt. But is this debt a concern to shareholders?
Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. 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, OXIDE had JP¥9.99b of debt, at August 2025, which is about the same as the year before. You can click the chart for greater detail. However, because it has a cash reserve of JP¥2.43b, its net debt is less, at about JP¥7.56b.
The latest balance sheet data shows that OXIDE had liabilities of JP¥5.95b due within a year, and liabilities of JP¥6.06b falling due after that. Offsetting this, it had JP¥2.43b in cash and JP¥1.11b in receivables that were due within 12 months. So it has liabilities totalling JP¥8.47b more than its cash and near-term receivables, combined.
While this might seem like a lot, it is not so bad since OXIDE has a market capitalization of JP¥20.3b, and so it could probably strengthen its balance sheet by raising capital if it needed to. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.
Check out our latest analysis for OXIDE
In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its interest cover). 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).
Weak interest cover of 2.1 times and a disturbingly high net debt to EBITDA ratio of 5.9 hit our confidence in OXIDE like a one-two punch to the gut. This means we'd consider it to have a heavy debt load. One redeeming factor for OXIDE is that it turned last year's EBIT loss into a gain of JP¥332m, over the last twelve months. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine OXIDE's ability to maintain a healthy balance sheet going forward.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So it is important to check how much of its earnings before interest and tax (EBIT) converts to actual free cash flow. In the last year, OXIDE created free cash flow amounting to 6.0% of its EBIT, an uninspiring performance. That limp level of cash conversion undermines its ability to manage and pay down debt.
To be frank both OXIDE's interest cover and its track record of managing its debt, based on its EBITDA, make us rather uncomfortable with its debt levels. Having said that, its ability to grow its EBIT isn't such a worry. Overall, we think it's fair to say that OXIDE has enough debt that there are some real risks around the balance sheet. If all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet. For example OXIDE has 2 warning signs (and 1 which is concerning) we think you should know about.
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.
