It is hard to get excited after looking at Aussie Broadband's (ASX:ABB) recent performance, when its stock has declined 25% over the past three months. It is possible that the markets have ignored the company's differing financials and decided to lean-in to the negative sentiment. Stock prices are usually driven by a company’s financial performance over the long term, and therefore we decided to pay more attention to the company's financial performance. Particularly, we will be paying attention to Aussie Broadband's ROE today.

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. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Is ROE Calculated?

ROE can be calculated by using the formula:

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

So, based on the above formula, the ROE for Aussie Broadband is:

3.9% = AU$7.4m ÷ AU$191m (Based on the trailing twelve months to December 2021).

The 'return' is the profit over the last twelve months. So, this means that for every A$1 of its shareholder's investments, the company generates a profit of A$0.04.

Why Is ROE Important For Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. We now need to evaluate how much profit the company reinvests or "retains" for future growth which then gives us an idea about the growth potential of the company. 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.

Aussie Broadband's Earnings Growth And 3.9% ROE

On the face of it, Aussie Broadband's ROE is not much to talk about. However, given that the company's ROE is similar to the average industry ROE of 3.9%, we may spare it some thought. But then again, Aussie Broadband's five year net income shrunk at a rate of 6.8%. Bear in mind, the company does have a slightly low ROE. Hence, this goes some way in explaining the shrinking earnings.

So, as a next step, we compared Aussie Broadband's performance against the industry and were disappointed to discover that while the company has been shrinking its earnings, the industry has been growing its earnings at a rate of 26% in the same period.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. 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.

Is Aussie Broadband Using Its Retained Earnings Effectively?

Aussie Broadband doesn't pay any dividend, meaning that potentially all of its profits are being reinvested in the business, which doesn't explain why the company's earnings have shrunk if it is retaining all of its profits. It looks like there might be some other reasons to explain the lack in that respect. For example, the business could be in decline.

Summary

In total, we're a bit ambivalent about Aussie Broadband's performance. While the company does have a high rate of reinvestment, the low ROE means that all that reinvestment is not reaping any benefit to its investors, and moreover, its having a negative impact on the earnings 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.
