In 2020 Matthew O’Brien, Ph.D. assumed day- to-day leadership and principal ownership of our firm. Mark O’Brien continues to serve as Chairman.

O’Brien Greene’s clientele consists of high-net-worth individuals, families, trusts, charities, and pension and profit-sharing plans. Investment Management Services Our firm's principal service is independent discretionary investment management, for which we receive a fixed fee based upon a percentage of assets under management. Our firm operates under a fiduciary duty to our clients, and neither the firm nor our employees sell stocks, bonds, insurance or other financial products, nor do we receive commissions on the purchases or sales of securities in client accounts, or other remuneration from banks, brokerages, or insurance companies. We work with each client to understand their particular financial circumstances, investment time-horizon, and risk tolerance in order to identify appropriate investment objectives and portfolio design. Each client account is individually reviewed and managed. Clients may impose restrictions on investing in certain securities or types of securities due to ethical or other concerns. Each quarter of the year O’Brien Greene composes and sends to our clients a market commentary letter along with a detailed portfolio appraisal and performance report for the preceding period. Clients are responsible for notifying us of material changes in their circumstances that impact their investment objectives or financial situation. Client portfolios managed by O’Brien Greene consist primarily of publicly-listed individual stocks, investment-grade corporate bonds, and U.S. government obligations. Depending upon client objectives, we may maintain positions in treasury bills, money market funds, or other cash equivalents, as well as supplement a client’s holdings in individuals stocks and bonds with certain exchange-traded funds. In addition to overseeing our clients’ separately-managed accounts, our firm is also the general partner of a private fund, viz., the O’Brien Greene Small-Capitalization Stock Fund, L.P. Our private fund was established in 1993 and invests primarily in small public companies. As a private limited partnership, our fund is available only to clients who meet defined accredited investor criteria and is only offered pursuant to a separate disclosure and offering document that details the fund’s objectives, operations, risks, fees and other material information. See “Performance-Based Fees and Side-By-Side Management” below. A subset of our accredit investor clients have chosen to invest in our private fund after reviewing its offering documents; we do not “put” clients into the fund at our own discretion. Financial Planning and Use of eMoney Advisor Software O’Brien Greene’s clients may request us to compose a customized financial plan in order to help them manage cash flow projections, saving objectives, charitable giving, stock option vesting, and so on. The firm generally does not charge an additional fee for basic planning, but may charge a negotiated hourly fee for more in-depth financial plans. To the extent requested by a client, O’Brien Green may recommend the services of other professionals for certain non-investment related purposes, such as trust and estate attorneys, accountants, insurance brokers, and so on. Clients are not under any obligation to engage the services of any such referred professional. We may provide clients who have financial planning needs with access to an online financial dashboard and planning software that we license on our clients’ behalf from eMoney Advisor, LLC. Clients who choose to use this dashboard and planning software are responsible for the input, maintenance, accuracy and completeness of their information. When clients input information about assets or accounts that O’Brien Greene does not manage, and are “held-away” at the direction of an unrelated third-party or self- directed by a client, we are not responsible for monitoring or overseeing these assets or accounts. The dashboard and planning software licensed from eMoney Advisor LLC provides clients access to financial planning concepts and tools which should not, in any manner whatsoever, be construed as services, advice, or recommendations provided by O’Brien Greene. Finally, we are not responsible for any adverse results a client may experience if the client engages in financial planning or uses other tools available through the eMoney software without O’Brien Greene’s assistance or oversight. Use of Mutual Funds and Exchange Trade Funds From time-to-time O’Brien Greene may purchase for its clients’ exchange-traded funds (ETFs) or mutual funds for diversification benefits or exposure to targeted asset classes. ETFs and mutual funds have fees and expenses apart from O’Brien Greene’s advisory fee. Wrap Fee Programs The firm does not participate in wrap-fee programs. Discretionary/Non-Discretionary Account Statistics The firm manages client assets on both a discretionary and non-discretionary basis. “Discretionary” means the firm has the authority to decide what securities to buy and sell without the client’s advance approval. As of December 31, 2022, the firm managed $377,170,000 in total assets; $335,678,492 is managed on a discretionary basis and $41,491,664 on a non-discretionary basis. Retirement Plan / IRA Rollover Recommendation Considerations O’Brien Greene may provide you recommendations and advice concerning your employer retirement plan or other qualified retirement account as part of our advisory services. A recommendation

may include you consider withdrawing the assets from your employer's retirement plan or other qualified retirement account and roll the assets over to an individual retirement account ("IRA"). Further, we may offer to you the availability of our advisory services for those funds and securities targeted to be rolled into an IRA or other account for which we charge advisory services management fee compensation. If you elect to roll the assets to an IRA that is subject to our advisory services under a written contract, we will charge you an asset-based fee. This practice presents a potential conflict of interest, because O’Brien Greene has an additional incentive to recommend a rollover to you for the purpose of generating fee-based compensation in addition to making a recommendation solely based upon your needs. O’Brien Greene acts as a fiduciary for all accounts it manages; however, for retirement plan and individual retirement accounts we have a specific responsibility to make certain required disclosures in conjunction with providing rollover advice as follows: When we provide investment advice to you regarding your retirement plan account or individual retirement account, we are fiduciaries within the meaning of Title I of the Employee Retirement Income Security Act and/or the Internal Revenue Code, as applicable, which are laws governing retirement accounts. The way we make money creates some conflicts with your interests, so we operate under a special rule that requires us to act in your best interest and not put our interest ahead of yours. Under this special rule’s provisions, we must:
• Meet a professional standard of care when making investment recommendations (give prudent advice);
• Never put our financial interests ahead of yours when making recommendations (give loyal advice);
• Avoid misleading statements about conflicts of interest, fees, and investments;
• Follow policies and procedures designed to ensure that we give advice that is in your best interest;
• Charge no more than is reasonable for our services; and
• Give you basic information about conflicts of interest. You are encouraged to investigate independently educational materials on the pros and cons of rolling over your 401k / pension into an IRA. Some important considerations are summarized below. You are under no obligation, contractually or otherwise, to complete the rollover. Furthermore, if you do complete the rollover, you are under no obligation to have the assets in an IRA managed by us. It is important for you to understand many employers permit former employees to keep their retirement assets in their company plan. Also, current employees can sometimes move assets out of their company plan before they retire or change jobs. In determining whether to complete the rollover to an IRA, and to the extent the following options are available, you should consider the costs and benefits of each. An employee will often have four options: 1. Leave the funds in your former employer's plan. 2. Move the funds to a new employer's retirement plan. 3. Cash out and take a taxable distribution from the plan. 4. Roll the funds into an IRA rollover account. Each of these options has advantages and disadvantages and before making a change we encourage you to speak with your CPA and/or tax attorney. If you are considering rolling over your retirement funds to an IRA for us to manage it is important you understand the following: 1. Determine whether the investment options in your employer's retirement plan address your needs or whether you might want to consider other types of investments a) Employer retirement plans generally have a more limited investment menu than IRAs. b) Employer retirement plans may have unique investment options not available to the public such as employer securities, or previously closed funds. 2. Your current plan may have lower fees than our fees. a) If you are interested in investing only in mutual funds, you should understand the cost structure of the share classes available in your employer's retirement plan and how the costs of those share classes compare with those available in an IRA. b) You should understand the various products and services you might take advantage of at an IRA provider and the potential costs of those products and services. c) It is likely you will not be charged a separate management fee and will not receive ongoing asset management services unless you elect to have such services. In the event your plan offers asset management or model management, there may be a fee associated with the services that is more or less than our asset management fee. 3. Our strategy may have higher risk than the option(s) provided to you in your plan. 4. Your current plan may offer financial advice, guidance, and/or model management or portfolio options at no additional cost. 5. If you keep your assets titled in a 401k or retirement account, you could potentially delay your required minimum distribution beyond age 70.5 (70 1⁄2). 6. Your 401k may offer more liability protection than a rollover IRA; each state law may vary. a) Generally, federal law protects assets in qualified plans from creditors. Since 2005, IRA assets have been generally protected from creditors in bankruptcies. However, there can be some exceptions to the general rules so you should consult an attorney if you are concerned about protecting your retirement plan assets from creditors. 7. You may be able to take out a loan on your 401k, but not from an IRA. 8. IRA assets can be accessed any time; however, distributions are subject to ordinary income tax and may also be subject to a 10% early distribution penalty unless they qualify for an exception such as disability, higher education expenses or the purchase of a home.
