Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). To keep the lesson grounded in practicality, we'll use ROE to better understand Tidewater Renewables Ltd. (TSE:LCFS).
Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.
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 Tidewater Renewables is:
8.2% = CA$14m ÷ CA$169m (Based on the trailing twelve months to September 2025).
The 'return' is the profit over the last twelve months. That means that for every CA$1 worth of shareholders' equity, the company generated CA$0.08 in profit.

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. If you look at the image below, you can see Tidewater Renewables has a lower ROE than the average (11%) in the Oil and Gas industry classification.
Unfortunately, that's sub-optimal. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. A high debt company having a low ROE is a different story altogether and a risky investment in our books.
Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. That will make the ROE look better than if no debt was used.
Tidewater Renewables does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.06. The combination of a rather low ROE and significant use of debt is not particularly appealing. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So I think it may be worth checking this free report on analyst forecasts for the company.
