OUR FIRM The current organizational structure of Berkshire was formed in 2007 when purchased by Kenneth J. Krogulski. Effective December 19, 2022, iM Square Holding 10 LLC purchased a non-controlling interest in Berkshire. iM Square Holding 10 LLC is a wholly owned subsidiary of iM Square Partners Holding, itself a wholly owned subsidiary of iM Square SAS, a Paris-based investment and development platform dedicated to the asset management business, which is owned by Legendre Holding 36, third non-controlling parties and managers. Legendre Holdings, a holding company, is majority-owned (>75%) by Eurazeo SE, a European investment firm. However, Berkshire continues to majority owned by Berkshire employees. As of December 31, 2023, Berkshire had total regulatory assets under management of $2,312,342,944 of which $2,225,716,855 were managed on a discretionary basis and $86,626,089 were managed non- discretionary basis. PORTFOLIO MANAGEMENT AND INVESTMENT ADVISORY SERVICES Berkshire provides portfolio management and investment supervisory services to individuals, foundations, endowments, trusts, estates, corporations, and pension and profit-sharing plans, an exchange traded fund (“ETF”), and private pooled investment vehicles (each a “client” and collectively the “clients”). We seek to tailor our services to meet the individual needs and objectives of our clients. Account management is generally guided by the stated investment objectives and risk tolerance of that client (i.e. growth, safety, income, etc.). These objectives may not always take into consideration all of the related factors applicable to the rendering of “investment supervisory services”; rather, individual clients will decide on the specific direction of their account and Berkshire will manage the account under that principle. Berkshire performs asset management services with respect to investment choices for a client’s asset allocation plan Berkshire will assist the client in establishing appropriate investment objectives and will supervise the chosen investment options of and for the allocation plan and monitor the investments based on criteria established in the Investment Policy Statement (as applicable) that the client has specified, or will specify (such assets hereinafter collectively referred to as the "Account"). Generally, we implement one of two equity strategies if an Account has an equity allocation: a “Core Equity Strategy” or a “Dividend Equity Strategy,” or a fixed income strategy—either “Taxable or “Tax-exempt” or a combination of both. The strategies are described in Item 8 of this brochure. PARTICIPATION IN THIRD PARTY ADVISORY PROGRAMS/WRAP FEE BUSINESS Berkshire participates and seeks to do business in several “wrap fee” programs, whereby Berkshire acts as a third-party money manager for clients of unaffiliated broker dealers and other registered investment advisors. While program specifics and delivery mechanics vary, in general, firms and their financial advisors are appointing Berkshire to manage a portion of their client’s assets in a particular Berkshire strategy according to the client’s overall asset allocation/financial plans. Program Financial Advisors meet directly with the clients in order to establish the relationship, investment goals and determine whether Berkshire’s strategy is suitable for the client. Berkshire generally does not meet directly with the clients and is appointed to manage a portion of client assets in the strategy that was approved by the sponsor’s due diligence team. Arrangements usually take two forms: dual contract manager traded separate accounts and model delivery separate accounts Form ADV Part 2A March 27, 2024 Page 5 Under the dual contract arrangements, separate accounts are referred to Berkshire by each Wrap Fee Program’s individual Financial Advisors or a Registered Investment Advisor. The client signs Berkshire’s management agreement, which specifies Berkshire will manage the portfolio in accordance with the strategy’s objective, and that Berkshire will have limited power of attorney over the account and earn a management fee specified in the contract. The client also signs a separate contract with the sponsor or the sponsor’s program fees. In this format, the sponsor will notify Berkshire of account openings, closings, deposits, withdrawals etc. Berkshire works with the sponsor to establish trading mechanics so Berkshire can effectively manage the portfolios in accordance with the equity strategy the client desires. In these arrangements, Berkshire is responsible for trading, implementation and monitoring of each portfolio. Berkshire systems are in place to allow portfolio managers to manage and monitor account performance, holdings, weightings in a way so results are relatively consistent from account to account and in alignment with the approved strategy. Berkshire fees are typically debited directly from client accounts in accordance with our billing practices subject to the oversight of the sponsor. Berkshire has no control over for other sponsor costs such as trading, advisor fees, or custody fees etc. Wrap sponsor

makes representations the Berkshire strategy under consideration is “suitable” for each client. These accounts are included in Berkshire’s separate wrap fee composite. Under model delivery or UMA format, Berkshire also acts as a third-party money manager for clients of unaffiliated broker dealers and other registered investment advisors. Each program sponsor sets the rules, fees and requirements for these programs. For a single fee, a program sponsor or its advisors may recommend our strategy, for use in client accounts. Unlike dual contract Separately Managed Account’s (“SMA”) listed above the majority of operations are handled entirely by the wrap program/UMA sponsor. Berkshire only provides a model portfolio holdings and percentage weightings. Berkshire at its discretion will notify the sponsor of changes to the model, as applicable. It is upon the wrap sponsor or overlay manager to implement trading and maintenance in compliance with the model. Most of these arrangements are covered by a detailed master sub advisory arrangement between Berkshire and the sponsor. While Berkshire provides models on a timely basis, changes or implementation are at the discretion of the sponsor or overlay manager. Since implementation is at the discretion of the sponsor, account performance is not included in any of Berkshire’s composites. Fees may vary from sponsor to sponsor based on a variety of factors including potential asset levels, technology, and market opportunity. There is no management agreement between Berkshire and the end client, and all of Berkshire’s fee is collected by the sponsor and then paid to Berkshire. Berkshire receives a percentage of the overall Sponsor’s Wrap Program Fee calculated based on the portion of the client’s assets that Berkshire manages. For more information please refer to the program sponsor’s wrap fee program brochure. Berkshire has contracts or dual contract agreements with a number of Wrap Fee and UMA sponsors. TAX ALPHA TRANSITION PROGRAM ("Tax Alpha Program”) The Tax Alpha Program is intended for large-cap taxable accounts whereby investment advisers engage Berkshire via a manager traded SMA. Berkshire then seeks to create a temporary hybrid portfolio that is comprised of Berkshire holdings and highly appreciated legacy positions of the prior manager, with the goal of creating a highly correlated client portfolio to the Berkshire Dividend Growth Strategy, while seeking to limit tax liability. POOLED INVESTMENT VEHICLES Berkshire is the general partner and investment advisor for two limited partnerships or private funds: Berkshire Growth Fund (“BGF”) and Berkshire Partnership (“BP”) (each a “Fund” and collectively the “Funds”). In no event should this brochure be considered to be an offer of interest in a private fund or relied upon in determining to invest. This is not an offer of, or an agreement to provide, advisory services directly to any recipient. Also, all Funds investors and qualified potential investors should refer to the Funds’ Confidential Private Offering Memorandum and other offering documents. Form ADV Part 2A March 27, 2024 Page 6 DEFINED CONTRIBUTION PLAN ADVISORY SERVICES Berkshire occasionally provides investment recommendations to Plan Sponsors based on an agreed upon Investment Policy Statement. Berkshire provides advice on selection of investment options and model portfolios for the Plans. Berkshire does not have investment discretion over plan participant’s accounts and thus do not report the funds as assets under management. However, Berkshire is available to participants to answer questions regarding the investment options available within their plan. The Investment Policy Statement and Plan Investment Options (as applicable) are reviewed with the Plan Sponsor annually. Plan sponsors choose their own custodians and third-party administrators. NON-DISCRETIONARY ADVISORY SERVICES Berkshire occasionally provides non-discretionary investment advisory services to clients whereby Berkshire provides recommendations or supervision of assets held by outside managers. In managing these non-discretionary relationships, Berkshire generally uses the same sources of information and investment research personnel as the Firm uses to manage other client accounts. These are clients of the program sponsor or investment adviser and not Berkshire’s client accounts. The program manager may receive or act upon a model portfolio concurrently or after we take similar actions for our client accounts. As a result, the program sponsor and the firm may compete for execution quality, price or timing. ETF SUBADVISOR Berkshire serves as subadvisor to iMGP Berkshire Dividend Growth Equity ETF (”BDVG”) an ETF, which is a series of the Litman Gregory Funds Trust. BDVG was launched on June 30, 2023, and iM Global Partner Fund Management LLC, is the investment adviser.
