| PWC Valuation Assessment KPMG Auditing and Accounting The objective of PWC’s work was to carry out a valuation assessment of Banco Inter in accordance with the criteria defined in applicable regulations for purposes of delisting from B3. For the purposes of ICVM 361, PWC’s work included the value calculation of Banco Inter's shares using the following methodologies: • Equity Value per Share; • Weighted Average Price of Share Quotation (“PMPCA”); and • Economic Value, calculated based on the methodologies of market multiples and comparable transactions. For the purposes of Art. 264, PWC also added the equity value calculation of Banco Inter and of Inter Platform using the discounted cash flow method (“DCF”).
