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. Its dividend payout ratio is 76% of profit, which means the company is paying out a majority of its earnings. The relatively limited profit reinvestment could slow the rate of future earnings growth. We'd be worried about the risk of a drop in earnings. 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. Dividends consumed 71% of the company's free cash flow last year, which is within a normal range for most dividend-paying organisations.

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?

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 fall far enough, the company could be forced to cut its dividend. This is why it's a relief to see Infomedia earnings per share are up 7.2% per annum over the last five years. While earnings have been growing at a credible rate, the company is paying out a majority of its earnings to shareholders. Therefore it's unlikely that the company will be able to reinvest heavily in its business, which could presage slower growth in the future.
