Readers hoping to buy Pinnacle Financial Partners, Inc. (NYSE:PNFP) for its dividend will need to make their move shortly, as the stock is about to trade ex-dividend. The ex-dividend date is one business day before a company's record date, which is the date on which the company determines which shareholders are entitled to receive a dividend. The ex-dividend date is of consequence because whenever a stock is bought or sold, the trade takes at least one business day to settle. Therefore, if you purchase Pinnacle Financial Partners' shares on or after the 7th of August, you won't be eligible to receive the dividend, when it is paid on the 28th of August.

The company's next dividend payment will be US$0.50 per share, on the back of last year when the company paid a total of US$2.00 to shareholders. Based on the last year's worth of payments, Pinnacle Financial Partners has a trailing yield of 1.9% on the current stock price of US$107.54. 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. Pinnacle Financial Partners paid out just 22% of its profit last year, which we think is conservatively low and leaves plenty of margin for unexpected circumstances.

Companies that pay out less in dividends than they earn in profits generally have more sustainable dividends. The lower the payout ratio, the more wiggle room the business has before it could be forced to cut the dividend.

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 earnings decline and the company is forced to cut its dividend, investors could watch the value of their investment go up in smoke. This is why it's a relief to see Pinnacle Financial Partners earnings per share are up 5.2% per annum over the last five years.

Another key way to measure a company's dividend prospects is by measuring its historical rate of dividend growth. Pinnacle Financial Partners has delivered 15% dividend growth per year on average over the past 10 years. It's encouraging to see the company lifting dividends while earnings are growing, suggesting at least some corporate interest in rewarding shareholders.

Final Takeaway

From a dividend perspective, should investors buy or avoid Pinnacle Financial Partners? Pinnacle Financial Partners has seen its earnings per share grow slowly in recent years, and the company reinvests more than half of its profits in the business, which generally bodes well for its future prospects. In summary, Pinnacle Financial Partners appears to have some promise as a dividend stock, and we'd suggest taking a closer look at it.

While it's tempting to invest in Pinnacle Financial Partners for the dividends alone, you should always be mindful of the risks involved.

Generally, we wouldn't recommend just buying the first dividend stock you see. Here's a curated list of interesting stocks that are strong dividend payers.
