📌 Verification of Confirmed Derivatives Market Measures Figures

This disclosure serves as a preliminary notice outlining the calculation formulas and implementation date for derivative market measures aligned with the rights offering schedule. Because confirmed numerical figures are derived by applying the closing stock price on the day prior to the ex-rights date into the provided formulas, checking the final measure results announced on that day is necessary for understanding the numerical determination structure.
