Read This Before Buying OZ Minerals Limited (ASX:OZL) For Its Dividend

Is OZ Minerals Limited (ASX:OZL) a good dividend stock? How can we tell? Dividend paying companies with growing earnings can be highly rewarding in the long term. Yet sometimes, investors buy a stock for its dividend and lose money because the share price falls by more than they earned in dividend payments.

With a 2.2% yield and a nine-year payment history, investors probably think OZ Minerals looks like a reliable dividend stock. A low yield is generally a turn-off, but if the prospects for earnings growth were strong, investors might be pleasantly surprised by the long-term results. Some simple analysis can offer a lot of insights when buying a company for its dividend, and we'll go through this below.

Payout ratios

Dividends are usually paid out of company earnings. If a company is paying more than it earns, then the dividend might become unsustainable - hardly an ideal situation. Comparing dividend payments to a company's net profit after tax is a simple way of reality-checking whether a dividend is sustainable. In the last year, OZ Minerals paid out 54% of its profit as dividends. This is a fairly normal payout ratio among most businesses. It allows a higher dividend to be paid to shareholders, but does limit the capital retained in the business - which could be good or bad.

Another important check we do is to see if the free cash flow generated is sufficient to pay the dividend. Unfortunately, while OZ Minerals pays a dividend, it also reported negative free cash flow last year. While there may be a good reason for this, it's not ideal from a dividend perspective.

With a strong net cash balance, OZ Minerals investors may not have much to worry about in the near term from a dividend perspective.

Dividend Volatility

From the perspective of an income investor who wants to earn dividends for many years, there is not much point buying a stock if its dividend is regularly cut or is not reliable. The first recorded dividend for OZ Minerals, in the last decade, was nine years ago. Although it has been paying a dividend for several years now, the dividend has been cut at least once by more than 20%, and we're cautious about the consistency of its dividend across a full economic cycle. During the past nine-year period, the first annual payment was AU$0.60 in 2010, compared to AU$0.23 last year. The dividend has fallen 62% over that period.

A shrinking dividend over a nine-year period is not ideal, and we'd be concerned about investing in a dividend stock that lacks a solid record of growing dividends per share.

Dividend Growth Potential

Given that dividend payments have been shrinking like a glacier in a warming world, we need to check if there are some bright spots on the horizon. It's good to see OZ Minerals has been growing its earnings per share at 31% a year over the past five years. With recent, rapid earnings per share growth and a payout ratio of 54%, this business looks like an interesting prospect if earnings are reinvested effectively.

Conclusion

When we look at a dividend stock, we need to form a judgement on whether the dividend will grow, if the company is able to maintain it in a wide range of economic circumstances, and if the dividend payout is sustainable. First, the company has a payout ratio that was within an average range for most dividend stocks, but it paid out virtually all of its generated cash flow. Next, earnings growth has been good, but unfortunately the dividend has been cut at least once in the past. In sum, we find it hard to get excited about OZ Minerals from a dividend perspective. It's not that we think it's a bad business; just that there are other companies that perform better on these criteria.
