This Brochure also describes the business practices of the General Partners, which operate as a single advisory business together with Basalt Infrastructure Partners. Each General Partner’s board will typically consist of representatives of the Adviser and directors independent of the Adviser. In addition to the activities and roles of the General Partners described above, the Adviser has engaged, and intends to continue to engage, its financial industry affiliate, Basalt Infrastructure Partners, LLC (the “Sub-Adviser”), which the Adviser wholly owns and which is separately registered with the SEC as an investment adviser, to provide investment advisory services regarding U.S. and Canadian infrastructure investments for each Fund. The Funds are private investment funds and invest through negotiated transactions primarily in infrastructure assets, or asset-backed companies operating essential energy, transport, communications and utilities in Western Europe and North America (such investments generally referred to herein as “portfolio companies”). Basalt’s investment advisory services to the Funds consist of identifying and evaluating investment opportunities, negotiating

the terms of investments, managing and monitoring investments and achieving dispositions for such investments. Where such investments consist of portfolio companies, the senior principals or other personnel of the Adviser or its affiliates generally serve on such portfolio companies’ respective boards of directors or otherwise act to influence control over management of portfolio companies in which the Funds have invested. Basalt’s advisory services to the Funds are detailed in the relevant private placement memoranda or other offering documents (each, a “Memorandum”), investment management agreements, limited partnership or other operating agreements or governing documents (each, a “Partnership Agreement” and, together with any relevant Memorandum, the “Governing Documents”) and are further described below under “Methods of Analysis, Investment Strategies and Risk of Loss.” In each case, Basalt Infrastructure Partners provides its advice on a non-discretionary basis to the relevant General Partner of a Fund, whose board of directors makes the investment decision on the Fund’s behalf. Each General Partner of a Fund is a wholly-owned subsidiary of Basalt Infrastructure Partners. Investors in each Fund (generally referred to herein as “investors” or “limited partners”) participate in the overall investment program for the relevant Fund, but in certain circumstances are excused from a particular investment due to legal, regulatory or other agreed-upon circumstances pursuant to the Governing Documents; for the avoidance of doubt, such arrangements generally do not and will not create an adviser-client relationship between the Adviser and any investor. Each Fund or the relevant General Partner generally enter into side letters or other similar agreements (“Side Letters”) with certain investors that have the effect of establishing rights (including economic or other terms) under, or altering or supplementing the terms of, the Governing Documents with respect to such investors. Additionally, as permitted by the Governing Documents, the General Partners expect to provide (or agree to provide) investment or co-investment opportunities (including the opportunity to participate in co-invest vehicles) to certain current or prospective investors or other persons, including other sponsors, market participants, finders, consultants and other service providers, portfolio company management or personnel, personnel of the Adviser and/or certain other persons associated with the Adviser and/or their affiliates alongside the relevant Fund’s transactions. Such co-investments typically involve investment and disposal of interests in the applicable portfolio company at the same time and on the same terms as the Fund making the investment. Additionally, for strategic and other reasons, a co-investor or co-invest vehicle (including a co-investing Fund) may be permitted to purchase a portion of an investment from one or more Funds after such Funds have consummated their investment in a portfolio company (also known as a post-closing sell- down or transfer) and fund such purchase (upon initial investment/acquisition of that interest) through Fund investor capital contributions and/or use of a Fund credit facility. Any such purchase from a Fund by a co-investor or co-invest vehicle generally occurs shortly after the Fund’s completion of the investment to avoid any changes in valuation of the investment, but in certain instances could be well after the Fund’s initial purchase. Where appropriate, and in Basalt’s sole discretion, Basalt is authorised to charge, on behalf of the Fund, interest on the purchase to the co- investor or co-invest vehicle (or otherwise equitably to adjust the purchase price under certain conditions), and to seek reimbursement to the relevant Fund for related costs. However, to the extent any such amounts are not so charged or reimbursed (including charges or reimbursements required pursuant to applicable law), they generally will be borne by the relevant Fund. A prospective Fund investor will need to consider whether a proposed investment vehicle is appropriate to the investor’s circumstances based on all relevant factors including, but not limited to, the investor’s investment objectives, liquidity requirements, tax situation and risk tolerance. Prospective investors are strongly encouraged to undertake appropriate due diligence, including but not limited to a review of relevant Fund offering materials. As of December 31, 2023, Basalt had approximately $7,924,239,408 in regulatory assets under management.
