Dividend paying stocks like Alliant Energy Corporation (NASDAQ:LNT) tend to be popular with investors, and for good reason - some research suggests a significant amount of all stock market returns come from reinvested dividends. Unfortunately, it's common for investors to be enticed in by the seemingly attractive yield, and lose money when the company has to cut its dividend payments.

While Alliant Energy's 3.0% dividend yield is not the highest, we think its lengthy payment history is quite interesting. When buying stocks for their dividends, you should always run through the checks below, to see if the dividend looks sustainable.

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 be form a view on if a company's dividend is sustainable, relative to its net profit after tax. Looking at the data, we can see that 62% of Alliant Energy's profits were paid out as dividends in the last 12 months. This is a fairly normal payout ratio among most businesses. It allows a higher dividend to be paid to shareholders, but does limit the capital retained in the business - which could be good or bad.

We also measure dividends paid against a company's levered free cash flow, to see if enough cash was generated to cover the dividend. Last year, Alliant Energy paid a dividend while reporting negative free cash flow. While there may be an explanation, we think this behaviour is generally not sustainable. It's positive to see that Alliant Energy's dividend is covered by both profits and cash flow, since this is generally a sign that the dividend is sustainable, and a lower payout ratio usually suggests a greater margin of safety before the dividend gets cut.

Is Alliant Energy's Balance Sheet Risky?

As Alliant Energy 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. Alliant Energy has net debt of 5.02 times its earnings before interest, tax, depreciation and amortisation (EBITDA) which implies meaningful risk if interest rates rise of earnings decline.

We calculated its interest cover by measuring its earnings before interest and tax (EBIT), and dividing this by the company's net interest expense. Interest cover of less than 5x its interest expense is starting to become a concern for Alliant Energy, and be aware that lenders may place additional restrictions on the company as well. High debt and weak interest cover are not a great combo, and we would be cautious of relying on this company's dividend while these metrics persist.

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 Alliant Energy's dividend payments. During this period the dividend has been stable, which could imply the business could have relatively consistent earnings power. During the past ten-year period, the first annual payment was US$0.75 in 2009, compared to US$1.42 last year. This works out to be a compound annual growth rate (CAGR) of approximately 6.6% a year over that time.

Dividends have grown at a reasonable rate over this period, and without any major cuts in the payment over time, we think this is an attractive combination.

Dividend Growth Potential

Dividend payments have been consistent over the past few years, but we should always check if earnings per share (EPS) are growing, as this will help maintain the purchasing power of the dividend. Earnings have grown at around 6.0% a year for the past five years, which is better than seeing them shrink! The rate at which earnings have grown is quite decent, and by paying out more than half of its earnings as dividends, the company is striking a reasonable balance between reinvestment and returns to shareholders.

We'd also point out that Alliant Energy issued a meaningful number of new shares in the past year. Regularly issuing new shares can be detrimental - it's hard to grow dividends per share when new shares are regularly being created.

Conclusion

To summarise, shareholders should always check that Alliant Energy's dividends are affordable, that its dividend payments are relatively stable, and that it has decent prospects for growing its earnings and dividend. First, the company has a payout ratio that was within an average range for most dividend stocks, but it paid out virtually all of its generated cash flow. Second, earnings growth has been mediocre, but at least the dividends have been relatively stable. While we're not hugely bearish on it, overall we think there are potentially better dividend stocks than Alliant Energy out there.

Earnings growth generally bodes well for the future value of company dividend payments. See if the 8 Alliant Energy analysts we track are forecasting continued growth with our free report on analyst estimates for the company.
