Siris has full discretionary authority with respect to investment decisions for the Funds, and its advice is made in accordance with the investment objectives and guidelines set forth in each Fund’s offering memorandum. This Brochure does not constitute an offer to sell or solicitation of an offer to buy any securities. Persons reviewing this Brochure should not construe this as an

offer to sell or solicitation of an offer to buy the securities of any of the Funds described herein. Any such offer or solicitation will be made only by means of a confidential private placement memorandum. As more fully described in each Fund’s private placement memorandum, Siris’ investment objective is to make investments principally in equity or equity-related securities or, in certain circumstances, debt investments in a variety of industries. Siris is not limited in the industries in which it can invest, but intends to focus on investment opportunities in the technology, telecommunications and technology-enabled business services sectors. Siris’ core investment strategy is to (i) understand fundamental market and/or technology transitions and the specific sectors that are impacted by these paradigm shifts, (ii) identify value businesses within these sectors that are in transitional stages, (iii) target mature, leading technology companies that have the potential to unlock growth vectors for long-term strategic positioning, (iv) structure a transaction around a disciplined purchase price and innovative structures that seek to optimize returns and minimize risk, (v) develop and implement a specific business plan to execute strategic value creation initiatives post acquisition, and (vi) successfully exit these investments in a manner designed to optimize returns. Siris’ operations-intensive strategy integrates a group of senior operating executives, consultants, advisors and other professionals in similar roles (“Operating Professionals”), who work closely with the Siris investment team in sourcing, diligencing and implementing post-acquisition operating improvements at target companies. In this context, “Operating Professionals” means operating executives and other similar consultants (regardless of title, including “Executive Partners”, “Executive Advisors” or “Operating Executives”). Please see Item 8 for a more detailed description of Siris’ investment strategies. The descriptions set forth in this Brochure of specific advisory services that Siris offers to the Funds should not be understood to limit in any way Siris’ investment activities. Siris is permitted to offer any advisory services, engage in any investment strategy and make any investment that Siris considers appropriate, subject to each Fund’s investment objectives and guidelines. The investment strategies Siris pursues are speculative and entail substantial risks. Investors should be prepared to bear a substantial loss of capital. There can be no assurance that the investment objectives of any Fund will be achieved. Siris’ advisory services for the Funds are detailed in the applicable limited partnership agreements or other governing agreements of the Funds (each, a “Partnership Agreement” and, together with any investment management agreements, relevant private placement memoranda or other offering documents, the “Governing Documents”), and are further described below under “Methods of Analysis, Investment Strategies and Risk of Loss.” Investors in the Funds (generally referred to herein as “investors” or “limited partners”) 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; such arrangements generally do not and will not create an adviser-client relationship between Siris and any investor. Certain Funds and/or the General Partners have entered into side letters or other similar agreements (“Side Letters”) with certain investors that have the effect of establishing different and preferential rights (including economic or other terms) under, or altering or supplementing the terms of, the relevant Governing Documents with respect to such investors. As of December 31, 2023, Siris manages approximately $7,264,345,445 in assets on a discretionary basis.
