Is Tsakos Energy Navigation (NYSE:TEN) A Risky Investment?

Warren Buffett famously said, '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, Tsakos Energy Navigation Limited (NYSE:TEN) does carry debt. But is this debt a concern to shareholders?

What Risk Does Debt Bring?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. 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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Tsakos Energy Navigation's Net Debt?

As you can see below, Tsakos Energy Navigation had US$1.82b of debt, at June 2025, which is about the same as the year before. You can click the chart for greater detail. However, it also had US$283.6m in cash, and so its net debt is US$1.54b.

A Look At Tsakos Energy Navigation's Liabilities

Zooming in on the latest balance sheet data, we can see that Tsakos Energy Navigation had liabilities of US$349.3m due within 12 months and liabilities of US$1.65b due beyond that. On the other hand, it had cash of US$283.6m and US$49.4m worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$1.67b.

The deficiency here weighs heavily on the US$692.6m company itself, as if a child were struggling under the weight of an enormous back-pack full of books, his sports gear, and a trumpet. So we'd watch its balance sheet closely, without a doubt. After all, Tsakos Energy Navigation would likely require a major re-capitalisation if it had to pay its creditors today.

View our latest analysis for Tsakos Energy Navigation

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 we wouldn't worry about Tsakos Energy Navigation's net debt to EBITDA ratio of 4.5, we think its super-low interest cover of 2.2 times is a sign of high leverage. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Worse, Tsakos Energy Navigation's EBIT was down 21% over the last year. If earnings continue to follow that trajectory, paying off that debt load will be harder than convincing us to run a marathon in the rain. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Tsakos Energy Navigation'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 we always check how much of that EBIT is translated into free cash flow. Over the last three years, Tsakos Energy Navigation saw substantial negative free cash flow, in total. While that may be a result of expenditure for growth, it does make the debt far more risky.

Our View

To be frank both Tsakos Energy Navigation's EBIT growth rate and its track record of staying on top of its total liabilities make us rather uncomfortable with its debt levels. And furthermore, its interest cover also fails to instill confidence. Considering everything we've mentioned above, it's fair to say that Tsakos Energy Navigation is carrying heavy debt load. If you play with fire you risk getting burnt, so we'd probably give this stock a wide berth. 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. For example Tsakos Energy Navigation has 3 warning signs (and 1 which is concerning) we think you should know about.

When all is said and done, sometimes its easier to focus on companies that don't even need debt. Readers can access a list of growth stocks with zero net debt 100% free, right now.
