Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' So it seems the smart money knows that debt - which is usually involved in bankruptcies - is a very important factor, when you assess how risky a company is. Importantly, Tidewater Inc. (NYSE:TDW) 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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. When we examine debt levels, we first consider both cash and debt levels, together.

How Much Debt Does Tidewater Carry?

You can click the graphic below for the historical numbers, but it shows that as of December 2023 Tidewater had US$734.4m of debt, an increase on US$169.0m, over one year. On the flip side, it has US$274.4m in cash leading to net debt of about US$460.0m.

How Healthy Is Tidewater's Balance Sheet?

The latest balance sheet data shows that Tidewater had liabilities of US$328.7m due within a year, and liabilities of US$696.3m falling due after that. On the other hand, it had cash of US$274.4m and US$268.4m worth of receivables due within a year. So it has liabilities totalling US$482.3m more than its cash and near-term receivables, combined.

Given Tidewater has a market capitalization of US$4.67b, it's hard to believe these liabilities pose much threat. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward.

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (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).

Tidewater's net debt is sitting at a very reasonable 1.5 times its EBITDA, while its EBIT covered its interest expense just 4.0 times last year. While these numbers do not alarm us, it's worth noting that the cost of the company's debt is having a real impact. Notably, Tidewater's EBIT launched higher than Elon Musk, gaining a whopping 658% on 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 Tidewater's ability to maintain a healthy balance sheet going forward.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So it's worth checking how much of that EBIT is backed by free cash flow. In the last two years, Tidewater's free cash flow amounted to 49% of its EBIT, less than we'd expect. That's not great, when it comes to paying down debt.

Our View

Tidewater's EBIT growth rate suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. But truth be told we feel its interest cover does undermine this impression a bit. When we consider the range of factors above, it looks like Tidewater is pretty sensible with its use of debt. That means they are taking on a bit more risk, in the hope of boosting shareholder returns. 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. These risks can be hard to spot. Every company has them, and we've spotted 3 warning signs for Tidewater (of which 1 is significant!) you should know about.
