This section of the Firm Brochure contains a general description of UBS O’Connor LLC (also referred to as “we,” “our,” the “Firm,” or “O’Connor”), as well as information regarding our ownership structure, the types of advisory services we provide and the investment instruments we use, how we tailor advisory services to client needs, and our participation in managed account programs (wrap fee programs). Firm background UBS O’Connor LLC, a Delaware limited liability company, is a wholly-owned subsidiary of UBS Asset Management (Americas) Inc. (“UBS AM”), a wholly-owned subsidiary of UBS Americas Inc., which is a wholly-owned subsidiary of UBS Americas Holding LLC, which in turn is owned by UBS AG and ultimately by UBS Group AG, a publicly traded Swiss corporation (SIX and NYSE: UBS) ("UBS"). The operational structure of UBS is comprised of the Corporate Center and four business divisions: Global Wealth Management, Personal & Corporate Banking, Asset Management and the Investment Bank. The UBS Asset Management business division was formed through the merger of Union Bank of Switzerland and Swiss Bank Corporation in 1998. O’Connor was established in January 2000 when a proprietary trading group within UBS’ Investment Bank Division was transferred to the UBS Asset Management business division, establishing a newly formed investment management entity which provides investment advisory services to various types of pooled investment vehicles and institutional separately managed accounts, which are further described in this Firm Brochure.. O’Connor has been registered with the U.S. Securities and Exchange Commission ("SEC") as an investment adviser since its establishment and is part of the UBS Asset Management business division of UBS. In addition to O’Connor, the UBS Asset Management business division is itself divided into multiple separate businesses that provide asset management services globally. 1. UBS AM offers discretionary and non-discretionary investment advisory, investment management and sub-advisory services to various clients through their Equities, Fixed Income, and Investment Solutions platforms and wrap fee programs. 2. UBS Hedge Fund Solutions ("HFS"), another wholly-owned subsidiary of UBS AM, offers investment advisory services regarding investments in pooled investment vehicles, some of which are registered under the Investment Company Act of 1940, as amended (the “Investment Company Act”), as well as institutional and ultra-high net worth investors. 3. UBS Real Estate & Private Markets ("REPM") includes: UBS Realty Investors LLC (“RE”), which offers real estate investments through commingled real estate funds and individually managed discretionary and non-discretionary real estate accounts; UBS Farmland Investors LLC (“Farmland”), which offers advice to clients in connection with the acquisition or sale and management of agricultural real estate; and direct real estate through infrastructure direct investment ("IDI") and multi-managers ("MM-RE"), which primarily construct bespoke portfolios and funds. 4. UBS Asset Management Trust Company (the "Trust Company") acts as trustee and investment manager to certain collective investment trusts. 5. UBS Fund Management Services ("FMS") provides administrative services primarily to traditional investment funds domiciled outside of the United States. The UBS AM, HFS, REPM, Trust Company and FMS businesses are not covered by this Firm Brochure. Types of advisory services O'Connor primarily provides both discretionary investment management services (clients who have authorized our firm to execute transactions for their accounts without prior approval) and non- discretionary investment advisory services (clients who require that transactions be either traded by or authorized by them in advance) to various types of pooled investment vehicles, (which may or may not be exempt from registration), and institutional separately managed accounts ("SMAs") (collectively, "Clients"). Specific investment objectives, strategies, risks, fees and expenses are described in detail in each Client's investment management agreement, confidential offering memorandum and/or other governing documents (each as applicable, and collectively, "Governing Documents"). Certain of O’Connor’s private investment vehicle Clients may operate under a fund-of-fund, multi- manager, or multi-strategy structure, where O’Connor selects a portfolio of different underlying funds or strategies for such Clients. O’Connor may also engage the services of sub-advisors for certain of its Client accounts. O'Connor generally uses a combination of fundamental and/or quantitative analysis when formulating its investment advice or managing Client assets, but may use additional or alternative approaches as it deems necessary or appropriate. Additionally, O’Connor may seek the advice and assistance of its non-U.S. affiliates within the UBS Asset Management business division in providing investment supervisory services to its U.S. clients (in such capacity, "Participating Affiliates").

Restrictions regarding certain types of services and investments O'Connor is a part of a global financial services firm and may be precluded from acquiring or selling certain securities or investments on behalf of itself and Clients as a result of inside information, conflicts of interests or other applicable laws or regulations. Ultimate ownership by a foreign bank (UBS) subjects O’Connor to certain provisions of the Bank Holding Company Act (“BHCA”). The BHCA may, in certain circumstances, limit our Client's ownership of stock issued by other U.S. companies and other bank holding companies that are subject to the BHCA. O'Connor Client accounts generally will not be able to invest in securities solely issued by UBS. O'Connor or UBS adhere to global policies that require compliance with relevant regulatory and legal requirements. An example of such a requirement would be sanctions, which are any measure or restriction (including those often referred to as embargoes), taken by one or more countries, their respective government agencies or by an international organization, which is aimed at restricting dealings of any kind with or involving another country, specific persons, legal entities, organizations or goods. O'Connor o r UBS may also deem certain additional countries or industries to be high risk and may restrict business activities with certain countries, governments, government controlled entities, territories or persons. In some cases, business activities are expressly prohibited, where other cases may require pre-approval from regional compliance personnel before any business activity can be considered. In addition, O'Connor has policies in place that prohibit securities of certain companies to be included in institutional funds and in discretionary mandates. Such prohibitions include, but are not limited to, a ban on companies involved in the development, production or purchase of cluster munitions and anti- personnel mines, pursuant to the Swiss Federal Act on War Materials. Similarly, other state, federal or national laws may restrict our Client's aggregate ownership of stock issued by certain companies. As a result of these possible limitations, O'Connor may not be able to purchase securities that our models would otherwise indicate that we should, and therefore an account would not participate in the "upside" of such purchase (if any). Assets under management Client regulatory assets under management for O’Connor as of December 31, 2022 are as follows: US Dollar Amount Discretionary: $14,941,616,740 Non-Discretionary $0 Total: $14,941,616,740
