Principal Ownership Axium Infrastructure US Inc. (the “US Manager”) is a Delaware corporation that was formed on October 22, 2012. The US Manager is wholly owned by Axium Infrastructure Inc., a corporation formed under the laws of Canada (the “Canadian Manager,”, and, together with the US Manager, the “Adviser”). The management team members of the Adviser, comprised of Pierre Anctil and other infrastructure investment professionals, own more than 89% (on a fully diluted basis) of the Canadian Manager. Advisory Services The US Manager provides investment advisory services to certain private investment funds, including AxInfra US LP (the “US Fund”) and its parallel fund AxInfra US (P-1) LP (the “US P-1 Fund” and together with the US Fund, the “US Country Funds”) and AxInfra NA II LP (the “NA II Fund”) and AxInfra US II LP (the “US II Fund”). The Canadian Manager provides investment advisory services to certain private investment funds, including Axium Infrastructure Canada II LP (the “Canadian Fund”, together with the US Country Funds, the NA II Fund, the US II Fund, and the other private investment Funds managed by the Adviser, the “Funds” and, each individually, a “Fund”). The US Manager provides advice to certain other accounts pursuing substantially the same investment strategy as the Funds and may provide investment advisory services to additional private investment funds created by it in the future (together with the US Country Funds, the NA II Fund and the US II Fund, the “Advised Funds”). Like the US Manager, the Canadian Manager is registered as an investment adviser with the SEC under the Advisers Act. The Funds target both operating assets and greenfield investment opportunities with the objective of investing in core energy, transportation and social infrastructure assets. The US Country Funds acquire

and hold investments in infrastructure assets located in the U.S. The Canadian Fund acquires and holds investments in infrastructure assets located in Canada. The other Funds are “feeder” funds that invest (directly or indirectly) in the US Country Funds and/or the Canadian Fund. Affiliates of the US Manager act as the general partners to each of the Funds (each, a “General Partner”). Pursuant to the terms of management, administrative or similar services agreements (generally referred to as “services agreements” herein), the General Partner of each Advised Fund will delegate to the US Manager substantially all its management rights and certain obligations under its limited partnership agreement. The US Manager has overall responsibility for the management of the Advised Funds. The US Manager’s investment advisory services to the Advised Funds include, among other things:
• sourcing investment opportunities;
• managing and arranging acquisitions or dispositions of investments;
• determining exit strategies for investments; and
• overseeing banking, cash management and financing arrangements for the Advised Funds. The US Manager tailors its advisory services to each Advised Fund’s investment strategy, as disclosed in such Advised Fund’s offering documents. The US Manager’s advisory services are described in further detail in the Advised Funds’ private placement memoranda, services agreements and partnership agreements, and in Item 8 below. Additionally, the US Manager may offer investors in the Advised Funds or third parties the opportunity to co-invest with an Advised Fund in certain portfolio companies. Assets under Management As of December 31, 2023, the US Manager had approximately $5,209,091,318 of assets under management (including assets under management through co-investments).
