Does Mercury NZ (NZSE:MCY) Have A Healthy Balance Sheet?

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.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We note that Mercury NZ Limited (NZSE:MCY) 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?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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. 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 Mercury NZ's Net Debt?

As you can see below, at the end of December 2023, Mercury NZ had NZ$2.01b of debt, up from NZ$1.70b a year ago. Click the image for more detail. On the flip side, it has NZ$89.0m in cash leading to net debt of about NZ$1.93b.

How Strong Is Mercury NZ's Balance Sheet?

According to the last reported balance sheet, Mercury NZ had liabilities of NZ$1.11b due within 12 months, and liabilities of NZ$3.61b due beyond 12 months. Offsetting this, it had NZ$89.0m in cash and NZ$538.0m in receivables that were due within 12 months. So it has liabilities totalling NZ$4.09b more than its cash and near-term receivables, combined.

This deficit isn't so bad because Mercury NZ is worth NZ$9.34b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But it's clear that we should definitely closely examine whether it can manage its debt without 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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

Mercury NZ's debt is 2.6 times its EBITDA, and its EBIT cover its interest expense 3.5 times over. Taken together this implies that, while we wouldn't want to see debt levels rise, we think it can handle its current leverage. Another concern for investors might be that Mercury NZ's EBIT fell 15% in the last year. If that's the way things keep going handling the debt load will be like delivering hot coffees on a pogo stick. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Mercury NZ's ability to maintain a healthy balance sheet going forward.

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 most recent three years, Mercury NZ recorded free cash flow worth 66% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This cold hard cash means it can reduce its debt when it wants to.
