Readers hoping to buy Vulcan Materials Company (NYSE:VMC) for its dividend will need to make their move shortly, as the stock is about to trade ex-dividend. 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. It is important to be aware of the ex-dividend date because any trade on the stock needs to have been settled on or before the record date. Therefore, if you purchase Vulcan Materials' shares on or after the 22nd of May, you won't be eligible to receive the dividend, when it is paid on the 5th of June.

The company's next dividend payment will be US$0.52 per share. Last year, in total, the company distributed US$2.08 to shareholders. Based on the last year's worth of payments, Vulcan Materials stock has a trailing yield of around 0.8% on the current share price of US$267.83. 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. Vulcan Materials is paying out just 23% of its profit after tax, which is comfortably low and leaves plenty of breathing room in the case of adverse events. That said, even highly profitable companies sometimes might not generate enough cash to pay the dividend, which is why we should always check if the dividend is covered by cash flow. It paid out 23% of its free cash flow as dividends last year, which is conservatively low.

It's positive to see that Vulcan Materials'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?

Stocks in companies that generate sustainable earnings growth often make the best dividend prospects, as it is easier to lift the dividend when earnings are rising. If business enters a downturn and the dividend is cut, the company could see its value fall precipitously. Fortunately for readers, Vulcan Materials's earnings per share have been growing at 14% a year for the past five years. Earnings per share are growing rapidly and the company is keeping more than half of its earnings within the business; an attractive combination which could suggest the company is focused on reinvesting to grow earnings further. This will make it easier to fund future growth efforts and we think this is an attractive combination - plus the dividend can always be increased later.

Another key way to measure a company's dividend prospects is by measuring its historical rate of dividend growth. In the last 10 years, Vulcan Materials has lifted its dividend by approximately 18% a year on average. It's great to see earnings per share growing rapidly over several years, and dividends per share growing right along with it.

To Sum It Up

Has Vulcan Materials got what it takes to maintain its dividend payments? We love that Vulcan Materials is growing earnings per share while simultaneously paying out a low percentage of both its earnings and cash flow. These characteristics suggest the company is reinvesting in growing its business, while the conservative payout ratio also implies a reduced risk of the dividend being cut in the future. 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.
