Regular readers will know that we love our dividends at Simply Wall St, which is why it's exciting to see Kennametal Inc. (NYSE:KMT) is about to trade ex-dividend in the next 3 days. The ex-dividend date is one business day before the record date, which is the cut-off date for shareholders to be present on the company's books to be eligible for a dividend payment. 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. Thus, you can purchase Kennametal's shares before the 12th of May in order to receive the dividend, which the company will pay on the 26th of May.

The company's next dividend payment will be US$0.20 per share, and in the last 12 months, the company paid a total of US$0.80 per share. Calculating the last year's worth of payments shows that Kennametal has a trailing yield of 1.9% on the current share price of US$41.71. Dividends are an important source of income to many shareholders, but the health of the business is crucial to maintaining those dividends. We need to see whether the dividend is covered by earnings and if it's growing.

If a company pays out more in dividends than it earned, then the dividend might become unsustainable - hardly an ideal situation. Kennametal paid out just 11% of its profit last year, which we think is conservatively low and leaves plenty of margin for unexpected circumstances. Yet cash flows are even more important than profits for assessing a dividend, so we need to see if the company generated enough cash to pay its distribution. It paid out 83% of its free cash flow as dividends, which is within usual limits but will limit the company's ability to lift the dividend if there's no growth.

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 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 encouraged by the steady growth at Kennametal, with earnings per share up 5.6% on average 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.

Another key way to measure a company's dividend prospects is by measuring its historical rate of dividend growth. Kennametal has delivered 1.1% dividend growth per year on average over the past 10 years.

Final Takeaway

Has Kennametal got what it takes to maintain its dividend payments? Earnings per share growth has been modest, and it's interesting that Kennametal is paying out less than half of its earnings and more than half its cash flow to shareholders in the form of dividends. In summary, it's hard to get excited about Kennametal from a dividend perspective.

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