We Think Gulf Marine Services (LON:GMS) Can Stay On Top Of Its Debt

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.' 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. We note that Gulf Marine Services PLC (LON:GMS) does have debt on its balance sheet. But the real question is whether this debt is making the company risky.

When Is Debt A Problem?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. Of course, plenty of companies use debt to fund growth, without any negative consequences. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Gulf Marine Services's Net Debt?

The image below, which you can click on for greater detail, shows that Gulf Marine Services had debt of US$189.7m at the end of June 2025, a reduction from US$245.9m over a year. However, it does have US$15.2m in cash offsetting this, leading to net debt of about US$174.5m.

How Healthy Is Gulf Marine Services' Balance Sheet?

We can see from the most recent balance sheet that Gulf Marine Services had liabilities of US$98.5m falling due within a year, and liabilities of US$164.9m due beyond that. On the other hand, it had cash of US$15.2m and US$36.5m worth of receivables due within a year. So its liabilities total US$211.7m more than the combination of its cash and short-term receivables.

This deficit is considerable relative to its market capitalization of US$259.4m, so it does suggest shareholders should keep an eye on Gulf Marine Services' use of debt. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.

Check out our latest analysis for Gulf Marine Services

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).

Gulf Marine Services has net debt worth 1.9 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 3.5 times the interest expense. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. If Gulf Marine Services can keep growing EBIT at last year's rate of 11% over the last year, then it will find its debt load easier to manage. 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 Gulf Marine Services'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.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Over the last three years, Gulf Marine Services actually produced more free cash flow than EBIT. There's nothing better than incoming cash when it comes to staying in your lenders' good graces.

Our View

On our analysis Gulf Marine Services's conversion of EBIT to free cash flow should signal that it won't have too much trouble with its debt. However, our other observations weren't so heartening. For example, its interest cover makes us a little nervous about its debt. When we consider all the factors mentioned above, we do feel a bit cautious about Gulf Marine Services's use of debt. While we appreciate debt can enhance returns on equity, we'd suggest that shareholders keep close watch on its debt levels, lest they increase. 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 instance, we've identified 2 warning signs for Gulf Marine Services that you should be aware of.
