WHO WE ARE. We are an investment adviser registered with the SEC under the Investment Advisers Act of 1940, as amended (the “Advisers Act”) and were established in May 26, 2016. We are a Delaware limited liability company. We are owned by The TCW Group, Inc. (the “TCW Group” and together with its affiliated companies, “TCW”), WAM Capital LLC (“WAM”), an affiliate of Wedbush Capital (“Wedbush”), certain members of our investment team (the “Investment Team”) and certain other minority owners (collectively, the “Ownership Group”). Initially, we are managed by a board of managers comprised of representatives from each of TCW and the Investment Team. In February 2013, TCW management and private investment funds affiliated with alternative asset manager The Carlyle Group (together with such affiliated funds, “Carlyle”) acquired TCW Group. On December 27, 2017, Nippon Life Insurance Company acquired a 24.75% minority stake in TCW Group. As a result of the transaction, TCW management and employees have increased their ownership in the firm to approximately 44.07% and Carlyle maintains a 31.18% interest in TCW Group. THE SERVICES WE OFFER. We provide investment advice and management services to Funds, as defined below, and separate accounts (each, an “Account”) that invest all or a significant portion of their assets in publicly-traded companies. We manage investments of the Funds, as defined below, in accordance with the investment objectives and strategies set forth in the Funds’ offering documents. Such investments are tailored to the Funds’ particular needs, but are not tailored to the individual needs of any Fund investor (limited partner). We manage Accounts in conformity with a client’s chosen strategy and clients have a limited ability to tailor such strategies or restrict certain securities. We provide investment advisory services to the following investment vehicles:  TCW Sepulveda Long/Short Equity Fund I LP, TCW Sepulveda Long/Short Equity Master Fund, Ltd., and TCW Sepulveda Focused Value Fund, LP (collectively, the “Funds”), whose investment objectives are to deliver attractive risk-adjusted returns while protecting capital in various market conditions. We seek to achieve the Funds’ investment objective by making value-oriented investments through an opportunistic, fundamentally- driven, long/short equity strategy, primarily in the equity securities of small capitalization

companies. We employ a focused, bottom-up research intensive and fundamental value- based approach to building a portfolio of high conviction investment opportunities. We seek to preserve capital and mitigate risk through limited diversification, hedging activities and adherence to a value-oriented investment philosophy. We will generally offer the Funds only to certain qualified institutional and individual investors. The terms of each Fund are described in its private placement memorandum and limited partnership agreement or similar agreement (“Offering Material”), which are delivered to each potential investor prior to the time they invest. Although the Funds are not managed with the specific objectives and risk tolerances of investors in mind, we may agree with certain Account clients on investment guidelines that restrict the securities or types of securities that we invest in on their behalf. ASSETS UNDER MANAGEMENT. As of December 31, 2022, we had $351,686,356 in discretionary assets under management and $0 in non-discretionary assets under management. The TCW Group of Companies, including affiliated entities, had approximately $205.2 billion in assets under management as of that date. IMPORTANT NOTICE.
