Investment in Equity Investee	Investment in Equity InvesteeIn the third quarter of 2023, the Company, through its wholly owned subsidiary EVERTEC Costa Rica, S.A. (“EVERTEC CR”), entered into an agreement with a corporate partner to jointly develop and provide payment services in the Latin America region. The services will be provided through a newly formed entity which both entities will contribute capital to form. The Company has concluded that the newly formed entity is a joint venture not controlled by the Company and will therefore account for the entity as an equity investee. The Company has committed capital contributions in the amount of $13.5 million, consisting of cash payments amounting to $7.5 million, nonfinancial assets consisting of $3.5 million in development of intellectual property, and $2.5 million in processing cost credits. At September 30, 2023, the Company had contributed $5.5 million in cash from the committed amounts, which represented 9.91% ownership in the joint venture.
