Sirius XM Holdings Inc. (NASDAQ:SIRI) stock is about to trade ex-dividend in four days. 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 important as the process of settlement involves a full business day. So if you miss that date, you would not show up on the company's books on the record date. In other words, investors can purchase Sirius XM Holdings' shares before the 11th of February in order to be eligible for the dividend, which will be paid on the 27th of February.

The company's next dividend payment will be US$0.27 per share, on the back of last year when the company paid a total of US$1.08 to shareholders. Calculating the last year's worth of payments shows that Sirius XM Holdings has a trailing yield of 4.8% on the current share price of US$22.60. Dividends are an important source of income to many shareholders, but the health of the business is crucial to maintaining those dividends. So we need to check whether the dividend payments are covered, and if earnings are growing.

If a company pays out more in dividends than it earned, then the dividend might become unsustainable - hardly an ideal situation. Fortunately Sirius XM Holdings's payout ratio is modest, at just 45% of profit. Yet cash flow is typically more important than profit for assessing dividend sustainability, so we should always check if the company generated enough cash to afford its dividend. Fortunately, it paid out only 29% of its free cash flow in the past year.

It's encouraging to see that the dividend is covered by both profit and cash flow. This generally suggests the dividend is sustainable, as long as earnings don't drop precipitously.

Have Earnings And Dividends Been Growing?

Businesses with strong growth prospects usually make the best dividend payers, because it's easier to grow dividends when earnings per share are improving. Investors love dividends, so if earnings fall and the dividend is reduced, expect a stock to be sold off heavily at the same time. That's why it's comforting to see Sirius XM Holdings's earnings have been skyrocketing, up 51% per annum for the past five years. Earnings per share have been growing very quickly, and the company is paying out a relatively low percentage of its profit and cash flow. This is a very favourable combination that can often lead to the dividend multiplying over the long term, if earnings grow and the company pays out a higher percentage of its earnings.

Another key way to measure a company's dividend prospects is by measuring its historical rate of dividend growth. Since the start of our data, nine years ago, Sirius XM Holdings has lifted its dividend by approximately 12% a year on average. Both per-share earnings and dividends have both been growing rapidly in recent times, which is great to see.

To Sum It Up

Should investors buy Sirius XM Holdings for the upcoming dividend? It's great that Sirius XM Holdings is growing earnings per share while simultaneously paying out a low percentage of both its earnings and cash flow. It's disappointing to see the dividend has been cut at least once in the past, but as things stand now, the low payout ratio suggests a conservative approach to dividends, which we like. It's a promising combination that should mark this company worthy of closer attention.

While it's tempting to invest in Sirius XM Holdings for the dividends alone, you should always be mindful of the risks involved.
