Readers hoping to buy Southside Bancshares, Inc. (NYSE:SBSI) for its dividend will need to make their move shortly, as the stock is about to trade ex-dividend. 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 Southside Bancshares' shares before the 18th of May to receive the dividend, which will be paid on the 1st of June.

The company's next dividend payment will be US$0.36 per share, and in the last 12 months, the company paid a total of US$1.44 per share. Based on the last year's worth of payments, Southside Bancshares stock has a trailing yield of around 4.4% on the current share price of US$32.67. If you buy this business for its dividend, you should have an idea of whether Southside Bancshares's dividend is reliable and sustainable. We need to see whether the dividend is covered by earnings and if it's growing.

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. Southside Bancshares is paying out an acceptable 61% of its profit, a common payout level among most companies.

Have Earnings And Dividends Been Growing?

Companies that aren't growing their earnings can still be valuable, but it is even more important to assess the sustainability of the dividend if it looks like the company will struggle to grow. If earnings decline and the company is forced to cut its dividend, investors could watch the value of their investment go up in smoke. With that in mind, we're not enthused to see that Southside Bancshares's earnings per share have remained effectively flat over the past five years. We'd take that over an earnings decline any day, but in the long run, the best dividend stocks all grow their earnings per share.

The main way most investors will assess a company's dividend prospects is by checking the historical rate of dividend growth. Southside Bancshares has delivered 4.3% dividend growth per year on average over the past 10 years.

The Bottom Line

From a dividend perspective, should investors buy or avoid Southside Bancshares? Southside Bancshares's earnings per share have been essentially flat, and the company is paying out more than half of its earnings as dividends to shareholders. These characteristics don't generally lead to outstanding dividend performance, and investors may not be happy with the results of owning this stock for its dividend.
