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. Importantly, Ormat Technologies, Inc. (NYSE:ORA) does carry debt. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

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. If things get really bad, the lenders can take control of the business. 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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is Ormat Technologies's Net Debt?

The chart below, which you can click on for greater detail, shows that Ormat Technologies had US$2.10b in debt in December 2023; about the same as the year before. However, it also had US$195.8m in cash, and so its net debt is US$1.90b.

A Look At Ormat Technologies' Liabilities

The latest balance sheet data shows that Ormat Technologies had liabilities of US$537.0m due within a year, and liabilities of US$2.22b falling due after that. On the other hand, it had cash of US$195.8m and US$270.2m worth of receivables due within a year. So its liabilities total US$2.29b more than the combination of its cash and short-term receivables.

While this might seem like a lot, it is not so bad since Ormat Technologies has a market capitalization of US$3.93b, 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.

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

While Ormat Technologies's debt to EBITDA ratio (4.8) suggests that it uses some debt, its interest cover is very weak, at 1.9, suggesting high leverage. It seems that the business incurs large depreciation and amortisation charges, so maybe its debt load is heavier than it would first appear, since EBITDA is arguably a generous measure of earnings. It seems clear that the cost of borrowing money is negatively impacting returns for shareholders, of late. Even more troubling is the fact that Ormat Technologies actually let its EBIT decrease by 8.1% over the last year. If that earnings trend continues the company will face an uphill battle to pay off 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 Ormat Technologies's ability to maintain a healthy balance sheet going forward. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So it's worth checking how much of that EBIT is backed by free cash flow. During the last three years, Ormat Technologies burned a lot of cash. 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.

Our View

To be frank both Ormat Technologies's interest cover and its track record of converting EBIT to free cash flow make us rather uncomfortable with its debt levels. And furthermore, its EBIT growth rate also fails to instill confidence. We're quite clear that we consider Ormat Technologies to be really rather risky, as a result of its balance sheet health. So we're almost as wary of this stock as a hungry kitten is about falling into its owner's fish pond: once bitten, twice shy, as they say. 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. We've identified 1 warning sign with Ormat Technologies , and understanding them should be part of your investment process.
