AGL Energy (ASX:AGL) has had a great run on the share market with its stock up by a significant 11% over the last three months. We wonder if and what role the company's financials play in that price change as a company's long-term fundamentals usually dictate market outcomes. Specifically, we decided to study AGL Energy's ROE in this article.

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How To Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for AGL Energy is:

13% = AU$703m ÷ AU$5.4b (Based on the trailing twelve months to June 2024).

The 'return' refers to a company's earnings over the last year. One way to conceptualize this is that for each A$1 of shareholders' capital it has, the company made A$0.13 in profit.

What Is The Relationship Between ROE And Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company’s earnings growth potential. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don’t share these attributes.

AGL Energy's Earnings Growth And 13% ROE

To start with, AGL Energy's ROE looks acceptable. Further, the company's ROE compares quite favorably to the industry average of 9.9%. For this reason, AGL Energy's five year net income decline of 12% raises the question as to why the high ROE didn't translate into earnings growth. Based on this, we feel that there might be other reasons which haven't been discussed so far in this article that could be hampering the company's growth. These include low earnings retention or poor allocation of capital.

That being said, we compared AGL Energy's performance with the industry and were concerned when we found that while the company has shrunk its earnings, the industry has grown its earnings at a rate of 8.3% in the same 5-year period.

Earnings growth is an important metric to consider when valuing a stock. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. By doing so, they will have an idea if the stock is headed into clear blue waters or if swampy waters await. Has the market priced in the future outlook for AGL?

Is AGL Energy Efficiently Re-investing Its Profits?

When we piece together AGL Energy's low three-year median payout ratio of 20% (where it is retaining 80% of its profits), calculated for the last three-year period, we are puzzled by the lack of growth. The low payout should mean that the company is retaining most of its earnings and consequently, should see some growth. It looks like there might be some other reasons to explain the lack in that respect. For example, the business could be in decline.

Moreover, AGL Energy has been paying dividends for at least ten years or more suggesting that management must have perceived that the shareholders prefer dividends over earnings growth. Upon studying the latest analysts' consensus data, we found that the company's future payout ratio is expected to rise to 57% over the next three years. Despite the higher expected payout ratio, the company's ROE is not expected to change by much.

Summary

On the whole, we do feel that AGL Energy has some positive attributes. However, given the high ROE and high profit retention, we would expect the company to be delivering strong earnings growth, but that isn't the case here. This suggests that there might be some external threat to the business, that's hampering its growth. With that said, we studied the latest analyst forecasts and found that while the company has shrunk its earnings in the past, analysts expect its earnings to grow in the future.
