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 Willis Lease Finance Corporation (NASDAQ:WLFC).
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. Simply put, it is used to assess the profitability of a company in relation to its equity capital.
The formula for return on equity is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders’ Equity
So, based on the above formula, the ROE for Willis Lease Finance is:
17% = US$123m ÷ US$714m (Based on the trailing twelve months to September 2025).
The ‘return’ is the amount earned after tax over the last twelve months. One way to conceptualize this is that for each $1 of shareholders’ capital it has, the company made $0.17 in profit.

Arguably the easiest way to assess company’s ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, Willis Lease Finance has a better ROE than the average (14%) in the Trade Distributors industry.
That’s what we like to see. Bear in mind, a high ROE doesn’t always mean superior financial performance. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.
Most companies need money — from somewhere — to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
It seems that Willis Lease Finance uses a huge volume of debt to fund the business, since it has an extremely high debt to equity ratio of 3.14. Its ROE is respectable, but it’s not so impressive once you consider all of the debt.
