Westinghouse Air Brake Technologies' (NYSE:WAB) stock is up by a considerable 21% over the past three months. As most would know, fundamentals are what usually guide market price movements over the long-term, so we decided to look at the company's key financial indicators today to determine if they have any role to play in the recent price movement. Specifically, we decided to study Westinghouse Air Brake Technologies' 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. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How Do You Calculate Return On Equity?

Return on equity 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 Westinghouse Air Brake Technologies is:

10% = US$1.1b ÷ US$10b (Based on the trailing twelve months to September 2024).

The 'return' refers to a company's earnings over the last year. That means that for every $1 worth of shareholders' equity, the company generated $0.10 in profit.

What Is The Relationship Between ROE And Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. 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.

A Side By Side comparison of Westinghouse Air Brake Technologies' Earnings Growth And 10% ROE

On the face of it, Westinghouse Air Brake Technologies' ROE is not much to talk about. Next, when compared to the average industry ROE of 15%, the company's ROE leaves us feeling even less enthusiastic. In spite of this, Westinghouse Air Brake Technologies was able to grow its net income considerably, at a rate of 23% in the last five years. We reckon that there could be other factors at play here. For example, it is possible that the company's management has made some good strategic decisions, or that the company has a low payout ratio.

We then compared Westinghouse Air Brake Technologies' net income growth with the industry and we're pleased to see that the company's growth figure is higher when compared with the industry which has a growth rate of 15% in the same 5-year period.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. 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 WAB?

Is Westinghouse Air Brake Technologies Using Its Retained Earnings Effectively?

Westinghouse Air Brake Technologies' three-year median payout ratio to shareholders is 16%, which is quite low. This implies that the company is retaining 84% of its profits. So it seems like the management is reinvesting profits heavily to grow its business and this reflects in its earnings growth number.

Additionally, Westinghouse Air Brake Technologies has paid dividends over a period of at least ten years which means that the company is pretty serious about sharing its profits with shareholders. Upon studying the latest analysts' consensus data, we found that the company's future payout ratio is expected to drop to 9.0% over the next three years. The fact that the company's ROE is expected to rise to 15% over the same period is explained by the drop in the payout ratio.

Conclusion

In total, it does look like Westinghouse Air Brake Technologies has some positive aspects to its business. Despite its low rate of return, the fact that the company reinvests a very high portion of its profits into its business, no doubt contributed to its high earnings growth.
