Most readers would already be aware that Tetra Tech's (NASDAQ:TTEK) stock increased significantly by 22% over the past three months. Given the company's impressive performance, we decided to study its financial indicators more closely as a company's financial health over the long-term usually dictates market outcomes. In this article, we decided to focus on Tetra Tech's ROE.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

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 Tetra Tech is:

17% = US$265m ÷ US$1.6b (Based on the trailing twelve months to March 2024).

The 'return' is the yearly profit. That means that for every $1 worth of shareholders' equity, the company generated $0.17 in profit.

What Is The Relationship Between ROE And Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. 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. Assuming all else is equal, companies that have both a higher return on equity and higher profit retention are usually the ones that have a higher growth rate when compared to companies that don't have the same features.

Tetra Tech's Earnings Growth And 17% ROE

To start with, Tetra Tech's ROE looks acceptable. Especially when compared to the industry average of 12% the company's ROE looks pretty impressive. This probably laid the ground for Tetra Tech's moderate 14% net income growth seen over the past five years.

We then compared Tetra Tech's 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 12% in the same 5-year period.

Earnings growth is a huge factor in stock valuation. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. Doing so will help them establish if the stock's future looks promising or ominous. Is TTEK fairly valued? This infographic on the company's intrinsic value has everything you need to know.
