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.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. As with many other companies BWX Technologies, Inc. (NYSE:BWXT) makes use of debt. But the real question is whether this debt is making the company risky.

When Is Debt A Problem?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. 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 step when considering a company's debt levels is to consider its cash and debt together.

What Is BWX Technologies's Net Debt?

The image below, which you can click on for greater detail, shows that at June 2022 BWX Technologies had debt of US$1.38b, up from US$1.18b in one year. On the flip side, it has US$71.2m in cash leading to net debt of about US$1.31b.

How Strong Is BWX Technologies' Balance Sheet?

According to the last reported balance sheet, BWX Technologies had liabilities of US$409.4m due within 12 months, and liabilities of US$1.59b due beyond 12 months. Offsetting this, it had US$71.2m in cash and US$721.0m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$1.21b.

This deficit isn't so bad because BWX Technologies is worth US$4.84b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.

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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

BWX Technologies has a debt to EBITDA ratio of 2.7, which signals significant debt, but is still pretty reasonable for most types of business. However, its interest coverage of 12.1 is very high, suggesting that the interest expense on the debt is currently quite low. One way BWX Technologies could vanquish its debt would be if it stops borrowing more but continues to grow EBIT at around 20%, as it did over the last year. 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 BWX Technologies'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, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. In the last three years, BWX Technologies created free cash flow amounting to 11% of its EBIT, an uninspiring performance. For us, cash conversion that low sparks a little paranoia about is ability to extinguish debt.

Our View

When it comes to the balance sheet, the standout positive for BWX Technologies 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 conversion of EBIT to free cash flow makes us a little nervous about its debt. When we consider all the elements mentioned above, it seems to us that BWX Technologies is managing its debt quite well. Having said that, the load is sufficiently heavy that we would recommend any shareholders keep a close eye on it. There's no doubt that we learn most about debt from the balance sheet. However, not all investment risk resides within the balance sheet - far from it. To that end, you should be aware of the 2 warning signs we've spotted with BWX Technologies .
