The Company Oberweis Asset Management, Inc. (“Oberweis”) was established in 1989 and is headquartered in suburban Chicago. Oberweis is an independent investment management firm that was founded to seek market inefficiencies in equities globally. Oberweis offers its strategies to retail clients and institutional investors via separately managed accounts (“SMAs”), its own proprietary mutual fund family, The Oberweis Funds, a private fund, Oberweis International Select Fund, LLC and through the provision of model portfolios. Established in 1989, Oberweis is headquartered in suburban Chicago, with additional equity research staff based in New York, London and Hong Kong. Oberweis Culture Oberweis is a bottom-up, active manager that searches for what we believe are superior fundamental, growth, and valuation characteristics in equities globally. The investment teams are led by James W. Oberweis. Teams are responsible for certain geographic areas. Teams employ disciplined and repeatable investment processes that focus on situations in which our proprietary analysis varies positively and materially from the expectations of other investors. The Oberweis culture promotes an entrepreneurial spirit. The team operates in a non- bureaucratic environment that permits timely communication, processing of new information, and nimble decision-making. Oberweis portfolios are managed by small autonomous teams of professionals who are compensated for success and isolated from bureaucracy. Our People Oberweis’ success starts with its people. Oberweis is 100% owned by its employees and the Oberweis family, with James W. Oberweis as the principal shareholder. Many senior professionals are also equity owners. Oberweis’ portfolio managers average 24 years of experience in the industry. Our Services Our retail investment advisory service includes high net-worth clients with accounts generally under $5 million in assets. Oberweis offers its retail advisory service both on a discretionary and non-discretionary basis. Clients can select between a small-cap account or a custom account. Small-cap accounts are invested in micro, small and medium capitalization high growth stocks. Custom accounts are typically also invested in high growth stocks, but a portion of those assets are invested in an appropriate mix of other types of equity securities, mutual funds (including The Oberweis Funds), exchange- traded funds and investment grade fixed income securities to seek to reduce volatility of returns over time. Custom accounts are invested according to the specific investment goals and risk preferences of each individual client. All client accounts are generally invested in a concentrated portfolio of securities that is suitable for the client based upon Oberweis’ understanding of the client’s financial

condition, investment objective and restrictions. Accordingly, a retail account investing in a similar strategy that Oberweis offers to an institutional account is likely not to own certain securities held by that institutional account and will experience different performance from those other advisory accounts. Oberweis does not provide comprehensive financial planning on behalf of its retail clients. The Oberweis financial consultant responsible for establishing and monitoring the client’s account will provide to the client, and, to the extent requested by the client, will assist the client in completing an account application designed to elicit information regarding the client’s financial situation (including cash flow needs), investment objective, goal and restrictions. This information and subsequent discussions with the client will be used by Oberweis to tailor the account’s risk profile and time horizon. The financial consultant also is responsible for assisting clients in making any revisions to their investment objectives should their financial position, investment requirements or goals change. Because of the varying objectives and restrictions of client accounts, it is likely that Oberweis will not be able to invest each account in an identical fashion. Oberweis Securities, Inc. (“OSI”), a registered broker/dealer under common control with Oberweis, executes substantially all trades for client accounts. Custody of most client accounts are maintained by National Financial Services Corporation LLC (“Custodian”), a registered broker-dealer, through which the transactions executed by Oberweis are cleared, or such other brokerage firm, bank or other financial institution as the client may choose. For further information on execution of trades and custodians, please see Brokerage Practices below. For certain international strategies, Oberweis may utilize investment research services provided by its wholly-owned affiliates, Oberweis Asset Management (Hong Kong) Limited (“OAMHK”), which are located in Hong Kong, and Oberweis Asset Management UK Limited (“OAMUK”), which is located in the United Kingdom. Oberweis also provides model portfolio services to certain unified managed account program sponsors. In providing these services, Oberweis does not provide investment advice to, nor does it have discretionary authority over, the accounts of the underlying clients of the sponsor. In that regard, Oberweis has no knowledge of the program sponsor's underlying clients, nor does it have any authority to effect trades on behalf of the sponsor's clients in furtherance of the model strategy. As of December 31, 2023, Oberweis’ total assets under management (both institutional and retail clients) were $3,044,047,364, of which Oberweis manages $3,043,520,409 on a discretionary and $526,955 on a non-discretionary basis.
