Regular readers will know that we love our dividends at Simply Wall St, which is why it's exciting to see Changgao Electric Group Co., Ltd. (SZSE:002452) is about to trade ex-dividend in the next three days. Typically, the ex-dividend date is one business day before the record date which is the date on which a company determines the shareholders eligible to receive a dividend. The ex-dividend date is important because any transaction on a stock needs to have been settled before the record date in order to be eligible for a dividend. Thus, you can purchase Changgao Electric Group's shares before the 10th of June in order to receive the dividend, which the company will pay on the 10th of June.

The company's next dividend payment will be CN¥0.07 per share, and in the last 12 months, the company paid a total of CN¥0.07 per share. Calculating the last year's worth of payments shows that Changgao Electric Group has a trailing yield of 1.0% on the current share price of CN¥6.73. If you buy this business for its dividend, you should have an idea of whether Changgao Electric Group's dividend is reliable and sustainable. So we need to investigate whether Changgao Electric Group can afford its dividend, and if the dividend could grow.

View our latest analysis for Changgao Electric Group

If a company pays out more in dividends than it earned, then the dividend might become unsustainable - hardly an ideal situation. Changgao Electric Group has a low and conservative payout ratio of just 16% of its income after tax. Yet cash flow is typically more important than profit for assessing dividend sustainability, so we should always check if the company generated enough cash to afford its dividend. Luckily it paid out just 15% of its free cash flow last year.

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.

Have Earnings And Dividends Been Growing?

Companies with consistently growing earnings per share generally make the best dividend stocks, as they usually find it easier to grow dividends per share. If business enters a downturn and the dividend is cut, the company could see its value fall precipitously. Fortunately for readers, Changgao Electric Group's earnings per share have been growing at 12% a year for the past five years. The company has managed to grow earnings at a rapid rate, while reinvesting most of the profits within the business. Fast-growing businesses that are reinvesting heavily are enticing from a dividend perspective, especially since they can often increase the payout ratio later.

We'd also point out that Changgao Electric Group issued a meaningful number of new shares in the past year. Trying to grow the dividend while issuing large amounts of new shares reminds us of the ancient Greek tale of Sisyphus - perpetually pushing a boulder uphill.

Another key way to measure a company's dividend prospects is by measuring its historical rate of dividend growth. Changgao Electric Group has delivered an average of 9.3% per year annual increase in its dividend, based on the past 10 years of dividend payments. We're glad to see dividends rising alongside earnings over a number of years, which may be a sign the company intends to share the growth with shareholders.

Final Takeaway

From a dividend perspective, should investors buy or avoid Changgao Electric Group? It's great that Changgao Electric Group is growing earnings per share while simultaneously paying out a low percentage of both its earnings and cash flow. It's disappointing to see the dividend has been cut at least once in the past, but as things stand now, the low payout ratio suggests a conservative approach to dividends, which we like. Overall we think this is an attractive combination and worthy of further research.

With that in mind, a critical part of thorough stock research is being aware of any risks that stock currently faces. Every company has risks, and we've spotted 2 warning signs for Changgao Electric Group you should know about.
