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 Tidewater is:

16% = US$175m ÷ US$1.1b (Based on the trailing twelve months to March 2025).

The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.16 in profit.

What Has ROE Got To Do With Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. 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.

A Side By Side comparison of Tidewater's Earnings Growth And 16% ROE

To start with, Tidewater's ROE looks acceptable. On comparing with the average industry ROE of 12% the company's ROE looks pretty remarkable. This certainly adds some context to Tidewater's exceptional 70% net income growth seen over the past five years. However, there could also be other causes behind this growth. 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.

As a next step, we compared Tidewater's net income growth with the industry and found that the company has a similar growth figure when compared with the industry average growth rate of 58% in the same period.

Earnings growth is an important metric to consider when valuing a stock. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. Doing so will help them establish if the stock's future looks promising or ominous. One good indicator of expected earnings growth is the P/E ratio which determines the price the market is willing to pay for a stock based on its earnings prospects. So, you may want to check if Tidewater is trading on a high P/E or a low P/E, relative to its industry.

Is Tidewater Using Its Retained Earnings Effectively?

Tidewater doesn't pay any regular dividends currently which essentially means that it has been reinvesting all of its profits into the business. This definitely contributes to the high earnings growth number that we discussed above.
