Mercury NZ (NZSE:MCY) Has A Somewhat Strained Balance Sheet

Some say volatility, rather than debt, is the best way to think about risk as an investor, but Warren Buffett famously said that 'Volatility is far from synonymous with risk.' 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, Mercury NZ Limited (NZSE:MCY) does carry debt. But the real question is whether this debt is making the company risky.

When Is Debt Dangerous?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. 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. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Mercury NZ's Net Debt?

You can click the graphic below for the historical numbers, but it shows that as of June 2021 Mercury NZ had NZ$1.53b of debt, an increase on NZ$1.35b, over one year. On the flip side, it has NZ$180.0m in cash leading to net debt of about NZ$1.35b.

A Look At Mercury NZ's Liabilities

We can see from the most recent balance sheet that Mercury NZ had liabilities of NZ$1.06b falling due within a year, and liabilities of NZ$2.74b due beyond that. On the other hand, it had cash of NZ$180.0m and NZ$320.0m worth of receivables due within a year. So it has liabilities totalling NZ$3.29b more than its cash and near-term receivables, combined.

While this might seem like a lot, it is not so bad since Mercury NZ has a market capitalization of NZ$8.62b, and so it could probably strengthen its balance sheet by raising capital if it needed to. However, it is still worthwhile taking a close look at its ability to pay off debt.

In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its interest cover). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

Mercury NZ's debt is 3.1 times its EBITDA, and its EBIT cover its interest expense 5.4 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. Unfortunately, Mercury NZ's EBIT flopped 14% over the last four quarters. If that sort of decline is not arrested, then the managing its debt will be harder than selling broccoli flavoured ice-cream for a premium. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Mercury NZ can strengthen its balance sheet over time.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So we always check how much of that EBIT is translated into free cash flow. Looking at the most recent three years, Mercury NZ recorded free cash flow of 44% of its EBIT, which is weaker than we'd expect. That's not great, when it comes to paying down debt.

Our View

Mercury NZ's EBIT growth rate was a real negative on this analysis, although the other factors we considered cast it in a significantly better light. But on the bright side, its ability to to cover its interest expense with its EBIT isn't too shabby at all. We should also note that Electric Utilities industry companies like Mercury NZ commonly do use debt without problems. When we consider all the factors discussed, it seems to us that Mercury NZ is taking some risks with its use of debt. While that debt can boost returns, we think the company has enough leverage now. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it.
