Each General Partner is subject to the Advisers Act pursuant to the Management Company’s registration in accordance with SEC guidance. This Brochure also describes the business practices of the General Partners, which operate as a single advisory business together with the Management Company. The Funds are private equity funds and invest through negotiated transactions in operating entities, generally referred to herein as “portfolio companies.” The Advisers’ 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. From time to time, where such investments consist of portfolio companies, the senior principals or other personnel of the Advisers or their 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. The Advisers’ 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 (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.” Investors in the Funds participate in the overall investment program for the applicable 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 Advisers and any investor. The Funds or the General Partners generally enter into side letters or other similar agreements (“Side Letters”) with certain investors that have the effect of establishing rights under, or altering or supplementing the terms (including economic or other terms) of, the Governing Documents with respect to such investors. Additionally, from time to time and as permitted by the Governing Documents, the Advisers 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, O2 personnel and/or certain other persons associated with O2 and/or its affiliates alongside a particular 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. However, from time to time, for strategic and other reasons, a co-investor or co-invest vehicle (including a co-investing Fund) purchases a portion of an investment from one or more Funds after such Funds have consummated their investment in the portfolio company (also known as a post-closing sell-down or transfer), which generally will have been funded 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. Where appropriate, and in an Adviser’s sole discretion, such Adviser reserves the right to charge 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 such amounts are not so charged or reimbursed, they generally will be borne by the relevant Fund. As of December 31, 2022, O2 managed $1,1 46,266,281 in client assets on a discretionary basis. The Management Company is principally owned and controlled by Todd Fink and Luke Plumpton.
