Zephyr Energy (LON:ZPHR) Has A Somewhat Strained Balance Sheet

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.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. Importantly, Zephyr Energy plc (LON:ZPHR) does carry debt. But the real question is whether this debt is making the company risky.

Why Does Debt Bring Risk?

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. 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, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest at high rates of return. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is Zephyr Energy's Debt?

As you can see below, at the end of June 2023, Zephyr Energy had US$33.7m of debt, up from US$28.6m a year ago. Click the image for more detail. However, because it has a cash reserve of US$6.19m, its net debt is less, at about US$27.5m.

How Strong Is Zephyr Energy's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Zephyr Energy had liabilities of US$37.7m due within 12 months and liabilities of US$14.7m due beyond that. Offsetting this, it had US$6.19m in cash and US$6.04m in receivables that were due within 12 months. So its liabilities total US$40.2m more than the combination of its cash and short-term receivables.

This deficit is considerable relative to its market capitalization of US$61.2m, so it does suggest shareholders should keep an eye on Zephyr Energy's use of debt. Should its lenders demand that it shore up the balance sheet, shareholders would likely face severe dilution.

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).

Even though Zephyr Energy's debt is only 1.5, its interest cover is really very low at 2.0. In large part that's it has so much depreciation and amortisation. While companies often boast that these charges are non-cash, most such businesses will therefore require ongoing investment (that is not expensed.) Either way there's no doubt the stock is using meaningful leverage. Shareholders should be aware that Zephyr Energy's EBIT was down 64% last year. If that earnings trend continues then paying off its debt will be about as easy as herding cats on to a roller coaster. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine Zephyr Energy'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 two years, Zephyr Energy saw substantial negative free cash flow, in total. 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 Zephyr Energy's conversion of EBIT to free cash flow and its track record of (not) growing its EBIT make us rather uncomfortable with its debt levels. But on the bright side, its net debt to EBITDA is a good sign, and makes us more optimistic. Overall, it seems to us that Zephyr Energy's balance sheet is really quite a risk to the business. For this reason we're pretty cautious about the stock, and we think shareholders should keep a close eye on its liquidity. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it.
