Is AltaGas Ltd. (TSE:ALA) A Great Dividend Stock?

Is AltaGas Ltd. (TSE:ALA) a good dividend stock? How can we tell? Dividend paying companies with growing earnings can be highly rewarding in the long term. 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.

A high yield and a long history of paying dividends is an appealing combination for AltaGas. We'd guess that plenty of investors have purchased it for the income. Some simple research can reduce the risk of buying AltaGas for its dividend - read on to learn more.

Payout ratios

Companies (usually) pay dividends out of their earnings. If a company is paying more than it earns, the dividend might have to be cut. So we need to form a view on if a company's dividend is sustainable, relative to its net profit after tax. In the last year, AltaGas paid out 31% of its profit as dividends. 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.

Another important check we do is to see if the free cash flow generated is sufficient to pay the dividend. Unfortunately, while AltaGas 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 AltaGas's Balance Sheet Risky?

As AltaGas has a meaningful amount of debt, we need to check its balance sheet to see if the company might have debt risks. A quick check of its financial situation can be done with two ratios: net debt divided by EBITDA (earnings before interest, tax, depreciation and amortisation), and net interest cover. Net debt to EBITDA measures total debt load relative to company earnings (lower = less debt), while net interest cover measures the ability to pay interest on the debt (higher = greater ability to pay interest costs). AltaGas has net debt of 6.92 times its 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 1.72 times its interest expense is starting to become a concern for AltaGas, and be aware that lenders may place additional restrictions on the company as well. Low interest cover and high debt can create problems right when the investor least needs them, and we're reluctant to rely on the dividend of companies with these traits.

Dividend Volatility

One of the major risks of relying on dividend income, is the potential for a company to struggle financially and cut its dividend. Not only is your income cut, but the value of your investment declines as well - nasty. AltaGas has been paying dividends for a long time, but for the purpose of this analysis, we only examine the past 10 years of payments. This dividend has been unstable, which we define as having been cut one or more times over this time. During the past ten-year period, the first annual payment was CA$2.16 in 2010, compared to CA$0.96 last year. The dividend has shrunk at around 7.8% a year during that period. AltaGas's dividend has been cut sharply at least once, so it hasn't fallen by 7.8% every year, but this is a decent approximation of the long term change.

A shrinking dividend over a ten-year period is not ideal, and we'd be concerned about investing in a dividend stock that lacks a solid record of growing dividends per share.

Dividend Growth Potential

Given that dividend payments have been shrinking like a glacier in a warming world, we need to check if there are some bright spots on the horizon. It's good to see AltaGas has been growing its earnings per share at 19% a year over the past five years. Earnings per share have been growing at a good rate, and the company is paying less than half its earnings as dividends. We generally think this is an attractive combination, as it permits further reinvestment in the business.

We'd also point out that AltaGas issued a meaningful number of new shares in the past year. Trying to grow the dividend when issuing new shares reminds us of the ancient Greek tale of Sisyphus - perpetually pushing a boulder uphill. Companies that consistently issue new shares are often suboptimal from a dividend perspective.

Conclusion

To summarise, shareholders should always check that AltaGas's dividends are affordable, that its dividend payments are relatively stable, and that it has decent prospects for growing its earnings and dividend. AltaGas has a low payout ratio, which we like, although it paid out virtually all of its generated cash. We were also glad to see it growing earnings, but it was concerning to see the dividend has been cut at least once in the past. Ultimately, AltaGas 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.
