Foci Fiber Optic Communications  (ROCO:3363) 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: Dec. 2025 )
=Net Income/Total Stockholders Equity
=-89.46/2555.578
=(Net Income / Revenue )*(Revenue / Total Assets)*(Total Assets / Total Stockholders Equity)
=(-89.46 / 1563.096)*(1563.096 / 3267.2635)*(3267.2635 / 2555.578)
=Net Margin %*Asset Turnover*Equity Multiplier
=-5.72 %*0.4784*1.2785
=ROA %*Equity Multiplier
=-2.74 %*1.2785
=-3.50 %

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: Dec. 2025 )
=Net Income/Total Stockholders Equity
=-89.46/2555.578
=(Net Income / Pre-Tax Income) * (Pre-Tax Income / Operating Income) * (Operating Income / Revenue) * (Revenue / Total Assets) * (Total Assets / Total Stockholders Equity)
= (-89.46 / -55.788) * (-55.788 / -143.288) * (-143.288 / 1563.096) * (1563.096 / 3267.2635) * (3267.2635 / 2555.578)
= Tax Burden * Interest Burden * Operating Margin % * Asset Turnover * Equity Multiplier
= 1.6036 * 0.3893 * -9.17 % * 0.4784 * 1.2785
=-3.50 %

Note: The net income data used here is four times the quarterly (Dec. 2025) net income data. The Revenue data used here is four times the quarterly (Dec. 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.
