Is Dedicare AB (publ) (STO:DEDI) a good dividend stock? How can we tell? Dividend paying companies with growing earnings can be highly rewarding in the long term. On the other hand, investors have been known to buy a stock because of its yield, and then lose money if the company's dividend doesn't live up to expectations.

In this case, Dedicare likely looks attractive to dividend investors, given its 6.4% dividend yield and eight-year payment history. It sure looks interesting on these metrics - but there's always more to the story . Before you buy any stock for its dividend however, you should always remember Warren Buffett's two rules: 1) Don't lose money, and 2) Remember rule #1. We'll run through some checks below to help with this.

Payout ratios

Dividends are typically paid from company earnings. If a company pays more in dividends than it earned, then the dividend might become unsustainable - hardly an ideal situation. As a result, we should always investigate whether a company can afford its dividend, measured as a percentage of a company's net income after tax. Dedicare paid out 89% of its profit as dividends, over the trailing twelve month period. It's paying out most of its earnings, which limits the amount that can be reinvested in the business. This may indicate limited need for further capital within the business, or highlight a commitment to paying a dividend.

Another important check we do is to see if the free cash flow generated is sufficient to pay the dividend. The company paid out 80% of its free cash flow as dividends last year, which is adequate, but reduces the wriggle room in the event of a downturn. It's encouraging to see that the dividend is covered by both profit and cash flow. This generally suggests the dividend is sustainable, as long as earnings don't drop precipitously.

While the above analysis focuses on dividends relative to a company's earnings, we do note Dedicare's strong net cash position, which will let it pay larger dividends for a time, should it choose.

Dividend Volatility

One of the major risks of relying on dividend income, is the potential for a company to struggle financially and cut its dividend. Not only is your income cut, but the value of your investment declines as well - nasty. Looking at the last decade of data, we can see that Dedicare paid its first dividend at least eight years ago. Although it has been paying a dividend for several years now, the dividend has been cut at least once, and we're cautious about the consistency of its dividend across a full economic cycle. During the past eight-year period, the first annual payment was kr1.00 in 2012, compared to kr2.60 last year. This works out to be a compound annual growth rate (CAGR) of approximately 13% a year over that time. The dividends haven't grown at precisely 13% every year, but this is a useful way to average out the historical rate of growth.

It's not great to see that the payment has been cut in the past. We're generally more wary of companies that have cut their dividend before, as they tend to perform worse in an economic downturn.

Dividend Growth Potential

With a relatively unstable dividend, it's even more important to evaluate if earnings per share (EPS) are growing - it's not worth taking the risk on a dividend getting cut, unless you might be rewarded with larger dividends in future. Dedicare has grown its earnings per share at 2.4% per annum over the past five years. Dedicare's earnings per share have barely grown, which is not ideal - perhaps this is why the company pays out the majority of its earnings to shareholders. When the rate of return on reinvestment opportunities falls below a certain minimum level, companies often elect to pay a larger dividend instead. This is why many mature companies often have larger dividend yields.

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, we think Dedicare is paying out an acceptable percentage of its cashflow and profit. Second, earnings growth has been ordinary, and its history of dividend payments is chequered - having cut its dividend at least once in the past. In sum, we find it hard to get excited about Dedicare 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.

Investors generally tend to favour companies with a consistent, stable dividend policy as opposed to those operating an irregular one. Still, investors need to consider a host of other factors, apart from dividend payments, when analysing a company. Taking the debate a bit further, we've identified 3 warning signs for Dedicare that investors need to be conscious of moving forward.
