Could Siemens Healthineers AG (ETR:SHL) be an attractive dividend share to own for the long haul? Investors are often drawn to strong companies with the idea of reinvesting the dividends. If you are hoping to live on the income from dividends, it's important to be a lot more stringent with your investments than the average punter.

Some readers mightn't know much about Siemens Healthineers's 2.0% dividend, as it has only been paying distributions for a year or so. Before you buy any stock for its dividend however, you should always remember Warren Buffett's two rules: 1) Don't lose money, and 2) Remember rule #1.

Payout ratios

Dividends are typically paid from company earnings. If a company pays more in dividends than it earned, then the dividend might become unsustainable - hardly an ideal situation. So we need to form a view on if a company's dividend is sustainable, relative to its net profit after tax. Siemens Healthineers paid out 49% of its profit as dividends, over the trailing twelve month period. This is a medium payout level that leaves enough capital in the business to fund opportunities that might arise, while also rewarding shareholders. Besides, if reinvestment opportunities dry up, the company has room to increase the dividend.

In addition to comparing dividends against profits, we should inspect whether the company generated enough cash to pay its dividend. The company paid out 68% of its free cash flow, which is not bad per se, but does start to limit the amount of cash Siemens Healthineers has available to meet other needs. 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.

Dividend Volatility

Before buying a stock for its income, we want to see if the dividends have been stable in the past, and if the company has a track record of maintaining its dividend. This company has been paying a dividend for less than 2 years, which we think is too soon to consider it a reliable dividend stock. Its most recent annual dividend was €0.70 per share.

We like that the dividend hasn't been shrinking. However we're conscious that the company hasn't got an overly long track record of dividend payments yet, which makes us wary of relying on its dividend income.
