Some investors rely on dividends for growing their wealth, and if you're one of those dividend sleuths, you might be intrigued to know that Nabaltec AG (ETR:NTG) is about to go ex-dividend in just 4 days. The ex-dividend date is usually set to be one business day before the record date which is the cut-off date on which you must be present on the company's books as a shareholder in order to receive the dividend. The ex-dividend date is of consequence because whenever a stock is bought or sold, the trade takes at least two business day to settle. In other words, investors can purchase Nabaltec's shares before the 26th of June in order to be eligible for the dividend, which will be paid on the 28th of June.

The company's upcoming dividend is €0.28 a share, following on from the last 12 months, when the company distributed a total of €0.28 per share to shareholders. Based on the last year's worth of payments, Nabaltec has a trailing yield of 1.8% on the current stock price of €15.90. Dividends are an important source of income to many shareholders, but the health of the business is crucial to maintaining those dividends. That's why we should always check whether the dividend payments appear sustainable, and if the company is growing.

If a company pays out more in dividends than it earned, then the dividend might become unsustainable - hardly an ideal situation. Nabaltec is paying out just 21% of its profit after tax, which is comfortably low and leaves plenty of breathing room in the case of adverse events. A useful secondary check can be to evaluate whether Nabaltec generated enough free cash flow to afford its dividend. Luckily it paid out just 12% of its free cash flow last year.

It's positive to see that Nabaltec's dividend is covered by both profits and cash flow, since this is generally a sign that the dividend is sustainable, and a lower payout ratio usually suggests a greater margin of safety before the dividend gets cut.

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. This is why it's a relief to see Nabaltec earnings per share are up 2.6% per annum over the last five years. Growth has been anaemic. Yet with more than 75% of its earnings being kept in the business, there is ample room to reinvest in growth or lift the payout ratio - either of which could increase the dividend.
