Regular readers will know that we love our dividends at Simply Wall St, which is why it's exciting to see Shenzhen Sunway Communication Co., Ltd. (SZSE:300136) is about to trade ex-dividend in the next couple of days. The ex-dividend date occurs one day before the record date which is the day on which shareholders need to be on the company's books in order to receive a dividend. The ex-dividend date is an important date to be aware of as any purchase of the stock made on or after this date might mean a late settlement that doesn't show on the record date. Meaning, you will need to purchase Shenzhen Sunway Communication's shares before the 14th of June to receive the dividend, which will be paid on the 14th of June.

The company's upcoming dividend is CN¥0.10 a share, following on from the last 12 months, when the company distributed a total of CN¥0.10 per share to shareholders. Last year's total dividend payments show that Shenzhen Sunway Communication has a trailing yield of 0.6% on the current share price of CN¥17.83. Dividends are a major contributor to investment returns for long term holders, but only if the dividend continues to be paid. As a result, readers should always check whether Shenzhen Sunway Communication has been able to grow its dividends, or if the dividend might be cut.

Dividends are typically paid from company earnings. If a company pays more in dividends than it earned in profit, then the dividend could be unsustainable. Shenzhen Sunway Communication has a low and conservative payout ratio of just 18% 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 11% 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?

When earnings decline, dividend companies become much harder to analyse and own safely. Investors love dividends, so if earnings fall and the dividend is reduced, expect a stock to be sold off heavily at the same time. With that in mind, we're discomforted by Shenzhen Sunway Communication's 12% per annum decline in earnings in the past five years. Ultimately, when earnings per share decline, the size of the pie from which dividends can be paid, shrinks.

Another key way to measure a company's dividend prospects is by measuring its historical rate of dividend growth. Shenzhen Sunway Communication has delivered 23% dividend growth per year on average over the past nine years.

The Bottom Line

Should investors buy Shenzhen Sunway Communication for the upcoming dividend? Earnings per share are down meaningfully, although at least the company is paying out a low and conservative percentage of both its earnings and cash flow. It's definitely not great to see earnings falling, but at least there may be some buffer before the dividend needs to be cut. While it does have some good things going for it, we're a bit ambivalent and it would take more to convince us of Shenzhen Sunway Communication's dividend merits.

With that in mind, a critical part of thorough stock research is being aware of any risks that stock currently faces. Case in point: We've spotted 1 warning sign for Shenzhen Sunway Communication you should be aware of.
