Readers hoping to buy Vonovia SE (ETR:VNA) for its dividend will need to make their move shortly, as the stock is about to trade ex-dividend. The ex-dividend date is commonly two business days before the record date, which is the cut-off date for shareholders to be present on the company's books to be eligible for a dividend payment. 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. Meaning, you will need to purchase Vonovia's shares before the 29th of May to receive the dividend, which will be paid on the 25th of June.

The company's next dividend payment will be €1.22 per share. Last year, in total, the company distributed €1.22 to shareholders. Based on the last year's worth of payments, Vonovia stock has a trailing yield of around 4.2% on the current share price of €28.99. We love seeing companies pay a dividend, but it's also important to be sure that laying the golden eggs isn't going to kill our golden goose! So we need to check whether the dividend payments are covered, and if earnings are growing.

Dividends are usually paid out of company profits, so if a company pays out more than it earned then its dividend is usually at greater risk of being cut. Vonovia lost money last year, so the fact that it's paying a dividend is certainly disconcerting. There might be a good reason for this, but we'd want to look into it further before getting comfortable. Given that the company reported a loss last year, we now need to see if it generated enough free cash flow to fund the dividend. If cash earnings don't cover the dividend, the company would have to pay dividends out of cash in the bank, or by borrowing money, neither of which is long-term sustainable. What's good is that dividends were well covered by free cash flow, with the company paying out 20% of its cash flow last year.

Have Earnings And Dividends Been Growing?

Companies with falling earnings are riskier for dividend shareholders. Investors love dividends, so if earnings fall and the dividend is reduced, expect a stock to be sold off heavily at the same time. Vonovia reported a loss last year, and the general trend suggests its earnings have also been declining in recent years, making us wonder if the dividend is at risk.
