Rosslyn Data Technologies  (LSE:RDT) ROE % Explanation

ROE % measures the rate of return on the ownership interest (shareholder's equity) of the common stock owners. It measures a firm's efficiency at generating profits from every unit of shareholders' equity (also known as net assets or assets minus liabilities). ROE % shows how well a company uses investment funds to generate earnings growth. ROE %s between 15% and 20% are considered desirable.

The factors that affect a company's ROE % can be illustrated with the three-step DuPont Analysis:

ROE %(Q: Oct. 2025 )
=Net Income/Total Stockholders Equity
=-2.75/0.4525
=(Net Income / Revenue )*(Revenue / Total Assets)*(Total Assets / Total Stockholders Equity)
=(-2.75 / 3.024)*(3.024 / 3.841)*(3.841 / 0.4525)
=Net Margin %*Asset Turnover*Equity Multiplier
=-90.94 %*0.7873*8.4884
=ROA %*Equity Multiplier
=-71.6 %*8.4884
=-607.73 %

With this breakdown, it is clear that if a company grows its Net Profit Margin, its Asset Turnover, or its Leverage, it can grow its ROE %.

The factors that affect a company's ROE % can also be illustrated with the five-step DuPont Analysis:

ROE %(Q: Oct. 2025 )
=Net Income/Total Stockholders Equity
=-2.75/0.4525
=(Net Income / Pre-Tax Income) * (Pre-Tax Income / Operating Income) * (Operating Income / Revenue) * (Revenue / Total Assets) * (Total Assets / Total Stockholders Equity)
= (-2.75 / -2.95) * (-2.95 / -2.786) * (-2.786 / 3.024) * (3.024 / 3.841) * (3.841 / 0.4525)
= Tax Burden * Interest Burden * Operating Margin % * Asset Turnover * Equity Multiplier
= 0.9322 * 1.0589 * -92.13 % * 0.7873 * 8.4884
=-607.73 %

Note: The net income data used here is two times the semi-annual (Oct. 2025) net income data. The Revenue data used here is two times the semi-annual (Oct. 2025) revenue data. The same rule applies to Pre-Tax Income and Operating Income.
* In the five-step DuPont Analysis, Operating Income is only available for non-financial companies. Thus, for Insurance companies, we use EBIT as a substitution of Operating Income. For Banks, both Operating Income and EBIT is unavailable. Thus we combined Interest Burden and Operating Margin % into Pretax Margin %, and the DuPont Analysis is divided into four components instead.

Be Aware

Net Income is used.

Because a company can increase its ROE % by having more financial leverage, it is important to watch the equity multiplier when investing in high ROE % companies. Like ROA %, ROE % is calculated with only 12 months data. Fluctuations in company's earnings or business cycles can affect the ratio drastically. It is important to look at the ratio from a long term perspective.

Asset light businesses require very few assets to generate very high earnings. Their ROE %s can be extremely high.
