For purposes of this Brochure, the “Adviser” means Stockbridge Partners LLC, a Delaware limited liability company, together (where the context permits) with its affiliates that serve as general partners of the Funds (as defined below) and other affiliates that provide advisory services to and/or receive management fees from Clients. Such affiliates may or may not be under common control with Stockbridge Partners LLC but possess a substantial similarity of personnel and/or equity owners with Stockbridge Partners LLC. These affiliates are generally formed for tax, regulatory or other purposes in connection with the organization of the Funds (as defined below). The Adviser is wholly owned by BPSP, L.P., which is in turn wholly owned by Berkshire Partners Holdings LLC. Berkshire Partners LLC (together with its affiliates, including general partner entities, that provide advisory services to and/or receive fees from pooled investment vehicles advised by Berkshire Partners LLC, “Berkshire”), which is also wholly owned by BPSP, L.P., is an investment adviser and affiliate of Stockbridge Partners LLC and has prepared a separate brochure and Form ADV. For the avoidance of doubt, the term “Adviser” as used herein does not include Berkshire, and the term “Berkshire” does not include the Adviser. The Adviser currently serves as the investment manager to certain funds in a master-feeder structure, including a “feeder” vehicle (the “Feeder Vehicle”) organized to invest exclusively in a fund engaging in investment activity (the “Main Fund”). The Adviser may also in the future organize and serve as general partner (or in an analogous capacity) to one or more “parallel funds” organized to invest with the Main Fund in a side-by-side structure and to one or more other feeder vehicles organized to invest exclusively in the Main Fund or in such parallel funds. As of the date of this Brochure, the Adviser also advises one separate account and may, in the future, advise others (each, an “Account,” and the clients for whom such Accounts are maintained, “Separate Account Clients”). The Main Fund and, where the context permits, the Feeder Vehicle, together with any other funds that the Adviser may from time to time advise, are each referred to as a “Fund” and collectively referred to as the “Funds”

and, together with the Separate Account Clients, the “Clients.” The Funds are exempt from registration under the Investment Company Act of 1940, as amended (the “1940 Act”), and the Funds’ interests are not registered under the Securities Act of 1933, as amended (the “Securities Act”). The Adviser’s services consist of identifying investment opportunities for Clients, and managing, monitoring, and disposing of such investments. The Adviser seeks to invest Client assets primarily in companies that exhibit earnings sustainability and growth due to the characteristics of the industries in which they compete, their positions within those industries and the capabilities of their management teams to execute their business plans. The Adviser focuses on investments with the potential for long-term capital appreciation, with a primary geographic focus in the United States, although the Adviser also pursues international investments on behalf of its Clients. Although the Adviser, on behalf of its Clients, primarily makes relatively long-term investments in publicly traded equities, the Adviser’s strategy allows for strategic short sales to hedge certain risks or to capitalize on market misunderstandings of fundamentals. Investment advice is provided directly to each Client, and not individually to investors in the Funds (in accordance with separate investment advisory, investment management, or portfolio management agreements, as applicable (each, an “Advisory Agreement”), the applicable governing agreement of a Fund (such as a limited partnership agreement or analogous organizational document (each, an “Organizational Document”)) and/or side letters with limited partners of a Fund (“Side Letters,” and together with the Advisory Agreements and the Organizational Documents, the “Governing Documents”)). A Client (or underlying investors in a Fund) may generally negotiate to impose investment restrictions in the Governing Documents of the applicable Fund or Account with respect thereto at the time the Fund or Account is established. The Adviser has been in business since 2006. As of December 31, 2022, the Adviser managed a total of $4,388,898,896 of Client assets, all of which is managed on a discretionary basis. The Adviser does not participate in wrap fee programs.
