INVESTMENT SERVICES Marble Trail Advisors is a fee-only investment advisory firm providing comprehensive wealth management services to individuals, families, and trusts who desire a deep long-term relationship with trusted financial professionals. Our holistic approach integrates financial planning and investment management. Financial Planning Our investment advisory services frequently begin with the preparation of a financial plan that identifies client goals and financial resources, analyzes the impact of client choices on the attainment of those goals, and identifies actions to achieve them. A typical financial plan will articulate savings, investment, and tax strategies to address retirement, education, and estate planning goals. When appropriate, Marble Trail will coordinate efforts with a client’s attorney, tax accountant, or insurance professional. Our services do not include legal counsel, asset custody, or the sale of any investment or insurance products. We view the financial plan as integral to the relationship and something we will update once a year, or whenever a client’s material financial circumstances or goals change. Investment Management Our investment advice is tailored to meet our clients’ needs and objectives. We document these in the Investment Policy Statement along with each client’s unique financial circumstances, risk tolerance and time horizon. Together these elements inform the investment approach that will maximize the client’s likelihood of attaining their goals. Our firm mainly uses equity securities, exchange traded funds, no-load mutual funds, corporate securities, municipal securities, and U.S. government securities in its portfolio management programs. We will monitor your portfolio’s performance on an ongoing basis and rebalance the portfolio whenever necessary, as changes occur in market conditions, your financial circumstances, or both. Our firm primarily

offers discretionary portfolio management services, which means we make investment decisions and place buy or sell orders in client accounts without explicit prior approval. Any actions taken will be based upon stated investment objectives as documented in the investment policy statement. Referral of Third-Party Money Managers For a portion of client accounts Marble Trail Advisors refers clients to a third-party money manager offering asset management and other investment advisory services. The third-party managers are responsible for continuously monitoring client accounts and making trades in client accounts when necessary. Under this program, we assist you with identifying your risk tolerance and investment objectives. We recommend third-party money managers in relation to your stated investment objectives and risk tolerance, and you may select a recommended third-party money manager or model portfolio based upon your needs. You must approve in writing use of the third-party money manager who provides your designated account with asset management services. We are available to answer questions that you may have regarding your account and act as the communication conduit between you and the third-party money manager. The third-party money manager may take discretionary authority to determine the securities to be purchased and sold for your account. We do not have any trading authority with respect to your designated account managed by the third-party money manager. Clients are advised that there may be other third-party managed programs not recommended by our firm, that are suitable for the client and that may be more or less costly than arrangements recommended by our firm. No guarantees can be made that a client’s financial goals or objectives will be achieved by a third-party investment adviser recommended by our firm. Further, no guarantees of performance can ever be offered by our firm (Please refer to Item 8 – Methods of Analysis, Investment Strategies and Risk of Loss for more details.) Assets Under Management As of March 25, 2024, Marble Trail Advisors managed discretionary assets of $427,920,210 and non-discretionary assets of $3,136,999.
