Cactus (NYSE:WHD) has had a great run on the share market with its stock up by a significant 12% over the last three months. Since the market usually pay for a company's long-term fundamentals, we decided to study the company's key performance indicators to see if they could be influencing the market. In this article, we decided to focus on Cactus' ROE.

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 Is ROE Calculated?

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 Cactus is:

20% = US$237m ÷ US$1.2b (Based on the trailing twelve months to September 2024).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.20 in profit.

Why Is ROE Important For 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. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.

Cactus' Earnings Growth And 20% ROE

To start with, Cactus' ROE looks acceptable. Further, the company's ROE compares quite favorably to the industry average of 14%. This probably laid the ground for Cactus' significant 29% net income growth seen over the past five years. We reckon that there could also 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 Cactus' net income growth with the industry and found that the company's growth figure is lower than the average industry growth rate of 53% in the same 5-year period, which is a bit concerning.

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 WHD?

Is Cactus Using Its Retained Earnings Effectively?

Cactus' three-year median payout ratio to shareholders is 21%, which is quite low. This implies that the company is retaining 79% 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.

Moreover, Cactus is determined to keep sharing its profits with shareholders which we infer from its long history of five years of paying a dividend. Our latest analyst data shows that the future payout ratio of the company is expected to drop to 14% over the next three years. However, the company's ROE is not expected to change by much despite the lower expected payout ratio.

Conclusion

Overall, we are quite pleased with Cactus' performance. Particularly, we like that the company is reinvesting heavily into its business, and at a high rate of return. As a result, the decent growth in its earnings is not surprising. With that said, the latest industry analyst forecasts reveal that the company's earnings growth is expected to slow down. Are these analysts expectations based on the broad expectations for the industry, or on the company's fundamentals? Click here to be taken to our analyst's forecasts page for the company.
