Today we'll take a closer look at Systemair AB (publ) (STO:SYSR) from a dividend investor's perspective. Owning a strong business and reinvesting the dividends is widely seen as an attractive way of growing your wealth. On the other hand, investors have been known to buy a stock because of its yield, and then lose money if the company's dividend doesn't live up to expectations.

A 1.7% yield is nothing to get excited about, but investors probably think the long payment history suggests Systemair has some staying power. There are a few simple ways to reduce the risks of buying Systemair for its dividend, and we'll go through these below.

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. Comparing dividend payments to a company's net profit after tax is a simple way of reality-checking whether a dividend is sustainable. Looking at the data, we can see that 41% of Systemair's profits were paid out as dividends in the last 12 months. A medium payout ratio strikes a good balance between paying dividends, and keeping enough back to invest in the business. Plus, there is room to increase the payout ratio over time.

We also measure dividends paid against a company's levered free cash flow, to see if enough cash was generated to cover the dividend. Unfortunately, while Systemair pays a dividend, it also reported negative free cash flow last year. While there may be a good reason for this, it's not ideal from a dividend perspective.

Is Systemair's Balance Sheet Risky?

As Systemair has a meaningful amount of debt, we need to check its balance sheet to see if the company might have debt risks. A quick way to check a company's financial situation uses these two ratios: net debt divided by EBITDA (earnings before interest, tax, depreciation and amortisation), and net interest cover. Net debt to EBITDA is a measure of a company's total debt. Net interest cover measures the ability to meet interest payments on debt. Essentially we check that a) a company does not have too much debt, and b) that it can afford to pay the interest. With net debt of 2.91 times its EBITDA, Systemair's debt burden is within a normal range for most listed companies.

Net interest cover can be calculated by dividing earnings before interest and tax (EBIT) by the company's net interest expense. With EBIT of 13.48 times its interest expense, Systemair's interest cover is quite strong - more than enough to cover the interest expense.

Dividend Volatility

From the perspective of an income investor who wants to earn dividends for many years, there is not much point buying a stock if its dividend is regularly cut or is not reliable. For the purpose of this article, we only scrutinise the last decade of Systemair's dividend payments. Its dividend payments have fallen by 20% or more on at least one occasion over the past ten years. During the past ten-year period, the first annual payment was kr0.75 in 2009, compared to kr2.00 last year. This works out to be a compound annual growth rate (CAGR) of approximately 10% a year over that time. Systemair's dividend payments have fluctuated, so it hasn't grown 10% every year, but the CAGR is a useful rule of thumb for approximating the historical growth.

It's not great to see that the payment has been cut in the past. We're generally more wary of companies that have cut their dividend before, as they tend to perform worse in an economic downturn.

Dividend Growth Potential

With a relatively unstable dividend, it's even more important to evaluate if earnings per share (EPS) are growing - it's not worth taking the risk on a dividend getting cut, unless you might be rewarded with larger dividends in future. Systemair's earnings per share have been essentially flat over the past five years. Over the long term, steady earnings per share is a risk as the value of the dividends can be reduced by inflation. A payout ratio below 50% leaves ample room to reinvest in the business, and provides finanical flexibility. However, earnings per share are unfortunately not growing much. Might this suggest that the company should pay a higher dividend instead?

Conclusion

To summarise, shareholders should always check that Systemair's dividends are affordable, that its dividend payments are relatively stable, and that it has decent prospects for growing its earnings and dividend. First, we like Systemair's low dividend payout ratio, although we're a bit concerned that it paid out a substantially higher percentage of its free cash flow. Unfortunately, earnings growth has also been mediocre, and the company has cut its dividend at least once in the past. Ultimately, Systemair comes up short on our dividend analysis. It's not that we think it is a bad company - just that there are likely more appealing dividend prospects out there on this analysis.

Earnings growth generally bodes well for the future value of company dividend payments. See if the 3 Systemair analysts we track are forecasting continued growth with our free report on analyst estimates for the company.
