Mattern Capital is a registered investment adviser solely owned by Perry Mattern and has been providing advisory services since 2019. As of December 31, 2023, Mattern Capital has $917,992,626 in discretionary regulatory assets under management. Mattern Capital offers a variety of advisory services, which include investment and wealth management, financial planning, and consulting services. Prior to Mattern Capital rendering any of the foregoing services, clients are required to enter into one or more written agreements with Mattern Capital setting forth the relevant terms and conditions of the advisory relationship (the “Advisory Agreement”). Mattern Capital manages investment portfolios for individuals, high net worth individuals, trusts, businesses and corporations. Mattern Capital will work with a client to determine the client's investment objectives and investor risk profile. These investment objectives may be set forth in a written Investment Policy Statement (IPS) that describes an asset allocation that conforms to a client’s risk tolerance level and expected rate of return requirements. Investment and portfolio allocation software is used to evaluate alternative portfolio designs. Mattern Capital evaluates clients’ existing investments with respect to their IPS and works with new clients to develop a plan to transition from a client’s existing portfolio to the portfolio recommended by Mattern Capital. Mattern Capital then continuously monitors clients’ portfolio holdings and holds regular review meetings with clients regarding their accounts, as necessary. Mattern Capital will utilize the financial information provided by the client to analyze and develop strategies and solutions to assist the client in meeting their financial goals. Mattern Capital will allocate a client’s assets among various investments taking into consideration the client’s unique ability, need, and willingness to take risk. Investment and Wealth Management Services Mattern Capital manages portfolios on a discretionary and, in very limited circumstances, non- discretionary basis. Mattern Capital may also provide its clients with a broad range of services, as described in more detail below. Mattern Capital advises its clients by delivering tailored wealth management services and solutions. These services are based on a comprehensive understanding of each client’s current situation, past experiences, and future goals. With this acquired knowledge Mattern Capital will create, analyze, strategize, and implement goal-oriented investment solutions. These solutions become our client’s investment policy. This policy and our matched strategies are designed to be risk appropriate, cost effective and tax efficient. Mattern Capital provides clients with wealth management services which generally include a broad range of comprehensive financial planning and consulting services, as well as discretionary and/or, in very limited circumstances, non-discretionary management of investment portfolios. Mattern Capital primarily allocates client assets among individual equity and debt securities, exchange-traded funds ("ETFs"), and institutional mutual funds in accordance with the client's stated investment objective and risk/volatility parameter. Mattern Capital may also occasionally recommend clients allocate a certain portion of their assets to independent investment managers ("Independent Managers"). Where appropriate, Mattern Capital may also provide advice about many types of legacy positions or other investments held in client portfolios. Clients may engage Mattern Capital to manage and/or advise on certain investment products that are not maintained at their primary custodian, such as variable life insurance and annuity contracts (to the extent permissible without an insurance license) and assets held in employer sponsored retirement plans and qualified tuition plans (i.e., 529 plans). In these situations, Mattern Capital will direct or make recommendations on a non-discretionary basis for the allocation of client assets among the various investment options available with the product. These assets are generally maintained at the underwriting insurance company or custodian for the plan trustee or administrator and clients retain responsibility for effecting trades in these accounts. Mattern Capital tailors its advisory services to meet the needs of its individual clients and seeks to manage client portfolios in a manner consistent with the client's investment objective and risk tolerance parameter. Mattern Capital consults with clients on an initial and ongoing basis to assess their specific risk tolerance, time horizon, liquidity constraints and other related factors relevant to the management of their portfolios. Clients are advised to promptly notify Mattern Capital if there are changes in their financial situation or if they wish to place any limitations on the management of their portfolios. Clients may impose reasonable restrictions or mandates on the management of their accounts if Mattern Capital determines, in its sole discretion, the conditions would not materially impact the performance of a management strategy or prove overly burdensome to the Firm's management efforts. To the extent a client decides to invest with an Independent Manager or in a particular fund, those managers and funds will have their own investment practices. Those investment practices are described in each managers’ Form ADV or fund’s prospectus, or in its offering or other disclosure documents. In addition, selected money managers or funds typically have discretion to determine the type and amount of securities to be purchased or sold for the client for that portion of the client’s assets managed by the money manager or fund. Mattern Capital makes available to clients the FICA® | For Advisors cash management program sponsored by StoneCastle Cash Management, LLC (‘StoneCastle’). The Federally Insured Cash Account program offered by StoneCastle allows customers the ability to protect their money by placing it in deposit accounts at banks, savings institutions and credit unions in a manner that maintains full insurance of the funds by the Federal Deposit Insurance Corporation (“FDIC”) or National Credit Union Administration (“NCUA”), whichever is applicable. Funds will be deposited within StoneCastle’s network of insured depositories. StoneCastle requires a $250,000 minimum deposit to open a FICA account. Mattern Capital does not receive compensation from StoneCastle if clients participate in this program, nor does Mattern Capital charge any additional fees for this service offering. Mattern Capital will assist clients in signing up for this program and facilitating the transfer of funds between the client’s like-named accounts. Clients participating

in this program will receive a copy of the StoneCastle Form ADV. Independent Managers As mentioned above, Mattern Capital may select certain Independent Managers to actively manage a portion of its clients' assets. Pursuant to the terms of the investment advisory agreement, Mattern Capital shall have the discretion to appoint and terminate these third-party advisers. The specific terms and conditions under which a client engages an Independent Manager may also be set forth in a separate written agreement with the designated Independent Manager. In addition to this brochure, clients will also receive the written disclosure documents of the respective Independent Managers engaged to manage their assets. Mattern Capital evaluates a variety of information about Independent Managers, which may include the Independent Managers' public disclosure documents, materials supplied by the Independent Managers themselves and other third-party analyses it believes are reputable. To the extent possible, Mattern Capital seeks to assess the Independent Managers' investment strategies, past performance and risk results in relation to its clients' individual portfolio allocations and risk exposure. Mattern Capital also takes into consideration each Independent Manager's management style, returns, reputation, financial strength, reporting, pricing and research capabilities, among other factors. Mattern Capital continues to provide services relative to the discretionary or non-discretionary selection of the Independent Managers. On an ongoing basis, Mattern Capital monitors the performance of those accounts being managed by Independent Managers. Mattern Capital seeks to ensure the Independent Managers' strategies and target allocations remain aligned with its clients' investment objectives and overall best interests. Financial Planning and Consulting Services Mattern Capital starts with an extensive review of a client's family situation which includes assets and liabilities as well as estate, tax, and insurance needs. The Firm then employs a risk tolerance and risk capacity-focused simulation to get a detailed cash flow analysis and proposed asset allocation. Together, this information is analyzed to develop a proposed financial plan, which is designed to be dynamic in nature, ever-evolving due to life changes resulting from changes in cash flow needs, risk tolerance, time horizon, or investment objectives. Mattern Capital’s financial planning and consulting services may include any or all of the following functions: Business Planning Liability Management Cash Flow Forecasting Risk Management Trust and Estate Planning Charitable Planning Financial Planning Distribution Planning Investment Consulting Tax Planning Insurance Planning Retirement Plan Consulting While each of these services is available on a stand-alone basis, certain of them may also be rendered in conjunction with investment portfolio management services, as part of a comprehensive wealth management engagement (described in more detail below). In performing these services, Mattern Capital is not required to verify any information received from the client or from the client's other professionals (e.g., attorneys, accountants, etc.), and is expressly authorized to rely on such information. Mattern Capital may recommend clients engage the firm for additional related services, or we may recommend other professionals to implement recommendations made by Mattern Capital. Such additional services by Mattern Capital or another professional will be provided for additional compensation, commensurate with the nature, extent, complexity, and other characteristics of such services. Clients are advised that a conflict of interest exists because the firm will have an incentive to recommend such additional services based on the compensation to be received, rather than solely based on the client's needs, and in some cases, based on the prospect of cross-referrals of advisory clients from the other professional or his or her firm. Mattern Capital also provides advice in the form of financial consultations. This service consists of consultations based on specific investment and financial concerns of the client. Consulting services may include, for example, assistance with establishing and implementing a retirement plan, preparation or review of an investment policy statement, the compilation of reports on various investment accounts, and asset allocation recommendations. The scope and depth of the consultation varies depending on the client's particular circumstances and needs. Mattern Capital provides financial planning and consulting services to non-advisory clients for a fixed fee or hourly fee. Clients are under no obligation to act upon any recommendations made by Mattern Capital under a financial planning or consulting engagement or to engage the services of a third-party professional. Clients retain the absolute right to decide whether or not to act on such recommendations, and if they choose to act on such recommendations, whether to engage the Firm or such professional for such services or to engage another investment adviser or professional of their choosing, which may charge less (or more) for such services. Should a client choose to implement the recommendations contained in the plan, Mattern Capital suggests the client work closely with his/her attorney, accountant and/or insurance agent. Implementation of financial plan recommendations is entirely at the client's discretion. Financial planning recommendations are of a generic nature and are not limited to any specific product or service offered by a broker dealer or insurance company. No Legal, Accounting or Tax Advice. Mattern Capital will act solely in its capacity as a registered investment advisor and does not provide any legal, accounting or tax advice. Client should seek the counsel of a qualified accountant and/or attorney when necessary. Mattern Capital may assist clients with tax harvesting and we will work with a client’s tax specialist to answer any questions related to the client’s portfolio account. Family Office Services Clients may desire services that are not part of our traditional wealth management, financial planning, or investment management engagement. Some examples include bill paying and expense management, various aspect of the estate settlement process, financial education for children and grandchildren, broad family support services, family meeting and governance, and many other highly customizable concierge level services. These services will be negotiated individually based on the complexity and time commitment required and billed separately through a consulting agreement and can be cancelled at any time by either party.
