The entities in Luxembourg are General Partners ( Associé Gérant Commandité ) of funds managed by Antin Infrastructure Partners SAS and Antin Infrastructure Partners UK Limited. 3.3 Changes in scope of consolidation Antin Infrastructure Partners S.A. was incorporated in June 2021. On the date of pricing of the IPO, pursuant to contribution agreements, the Initial Shareholders of Antin Infrastructure Partners SAS and Antin Infrastructure Partners UK Limited have contributed to the Company all of the shares of AIP SAS and AIP UK in exchange for newly issued shares of the Company. Following the contributions in kind, Antin Infrastructure Partners S.A. became the parent company of the Group. Prior to the contributions in kind, AIP SAS and AIP UK were two sub-groups under common ownership and control by the partners of Antin. The contribution transactions are outside the scope of IFRS 3 because the entities AIP SAS and AIP UK have been under common control prior to the contributions in kind. Additional changes to the scope of consolidation during the year ended 31 December 2021 relate to the incorporation of Antin Infrastructure Partners Asia Private Limited in Singapore and the subsidiaries Antin Nextgen Infra Fund I FP GP and GP.

In June 2021, Antin Infrastructure Partners SAS subscribed to the entire share capital of Antin Infrastructure Partners Asia Private Limited, a newly incorporated entity based in Singapore with the objective to increase Antin’s presence in Asia. In August 2021, Antin Infrastructure Partners SAS subscribed to the entire share capital of two newly incorporated entities, Antin Nextgen Infra Fund I Luxembourg FP GP and Antin Nextgen Infra Fund I Luxembourg GP, in order to manage a new growth-oriented infrastructure investment strategy focused on tomorrow’s infrastructure. 3.4 Antin Funds The Antin Funds are managed by a Fund Manager (AIP SAS or AIP UK). The Fund Manager is a direct subsidiary of Antin Infrastructure Partners S.A. The authority and powers of the Fund Manager are defined in the Limited Partnership Agreement of each fund. Determining whether or not a Fund Manager should consolidate its managed funds is based on judgments of whether the Fund Manager is acting in the capacity of a principal or in the capacity of an agent to the fund. Antin is acting in a capacity of an agent and therefore does not consolidate the Antin Funds in its financial statements.
