Only holders of the Company’s Class B voting common stock (“Class B Stock”) on the record date are entitled to vote at the Meeting and any adjournments thereof. In accordance with the provisions of the Delaware General Corporation Law (the “DGCL”), we will prepare a list of the holders of our Class B Stock (the “Class B Stockholders”) as of the record date. Class B Stockholders named in the list will be entitled to vote their Class B Stock on the matters to be voted on at the Meeting. Holders of Class A non-voting common stock (“Class A Stock”) of the Company are entitled to listen to and view the Meeting and any adjournments thereof, and to submit questions for consideration and response at or after the Meeting by emailing info@opco.com. However, holders of the Company’s Class A Stock (the “Class A Stockholders”) are not entitled to vote with respect to the matters referred to above.

(1)

The election of E. Behrens, T.M. Dwyer, P.M. Friedman, T.A. Glasser, S.J. Kanter, A.G. Lowenthal, R.S. Lowenthal, R.L. Roth and S.E. Spaulding as directors;

(6)

Any other business as may be proper to transact at the Meeting.

•

•

FOR the ratification of the appointment of Deloitte & Touche LLP as our auditors for 2026 and the authorization of our Audit Committee to fix the auditors’ remuneration;

•

•

FOR the approval, in an advisory (non-binding) vote, that a stockholder vote to approve the Company’s executive compensation (Matter 3 above) should occur every 3 years;

•

FOR the approval of the Company’s Amended and Restated Certificate of Incorporation.

Will any other matters be voted on?

The Board of Directors does not intend to present any other matters at the Meeting. The Board of Directors does not know of any other matters that will be brought before our Class B Stockholders for a vote at the Meeting. If any other matter is properly brought before the Meeting, your signed proxy card gives authority to A.G. Lowenthal and D.P. McNamara, as proxies, with full power of substitution, to vote on such matters at their discretion.

How many votes do I have?

Class B Stockholders are entitled to one vote for each share of Class B Stock held as of the close of business on the record date. Holders of Class A Stock are not entitled to vote with respect to the matters referenced above.

What is the difference between holding shares as a stockholder of record and as a beneficial owner?

Many stockholders hold their shares through a broker or bank rather than directly in their own names. As summarized below, there are some distinctions between shares held of record and those owned beneficially.

Stockholder of Record — If your shares are registered directly in your name with our transfer agent, you are considered, with respect to those shares, the stockholder of record, and these proxy materials are being made directly available to you by us. Class B Stockholders may vote the shares registered directly in your name by completing and mailing the proxy card or by submitting a vote electronically on the day of the Meeting.

Beneficial Owner — If your shares are held in a stock brokerage account or by a bank, you are considered the beneficial owner of shares held in street name, and these proxy materials are being forwarded to you by your bank or broker, which is considered the stockholder of record of those shares. As the beneficial owner (if you are a Class B Stockholder), you have the right to direct your bank or broker how to vote and are also invited to attend the Meeting. However, because you are not the stockholder of record, you may not vote those shares at the Meeting unless you bring with you a legal proxy from the stockholder of record. If you are a Class B Stockholder, your bank or broker has enclosed a voting instruction card providing directions for how to vote your shares.

How do I vote?

If you are a Class B Stockholder of record, there are three ways to vote:

•

By completing and depositing your proxy with our transfer agent no later than the last business day preceding the date of the Meeting;

•

By depositing it with our Secretary on the day of the Meeting by emailing it to info@opco.com, Attention: Secretary; or

•

By submitting a vote electronically on the day of the Meeting.

If you are a Class B Stockholder and you return your proxy card, but you do not indicate your voting preferences, the proxies will vote your shares FOR Matters 1, 2, 3, 5 and FOR 3 years with respect to Matter 4, and will use their discretion on any other matters that are submitted for stockholder vote at the Meeting.

Class B Stockholders who are not stockholders of record and who wish to file proxies should follow the instructions of their intermediary with respect to the procedure to be followed. Generally, Class B Stockholders who are not stockholders of record will be provided with either (i) a proxy executed by the intermediary, as the stockholder of record, but otherwise uncompleted and the beneficial owner may complete the proxy and return it directly to our transfer agent; or (ii) a request for voting instructions by the intermediary, as the stockholder of record, and then the intermediary must send to our transfer agent an executed proxy form completed in accordance with any voting instructions received by it from the beneficial owners and may not vote in the event that no instructions are received.

Can I change my vote or revoke my proxy?

bearing a later date and returning such proxy to our Secretary prior to the commencement of the Meeting. In addition, a Class B Stockholder who has given a proxy has the power to revoke it after the commencement of the Meeting as to any matter on which a vote has not been cast under the proxy by delivering written notice of revocation to our Secretary by sending an email to info@opco.com, Attention: Secretary.

How are votes counted?

We will appoint an Inspector of Election at the Meeting. The Inspector of Election is typically a representative of our transfer agent. The Inspector of Election will collect all proxies and ballots and tabulate the results.

Who pays for soliciting proxies?

We will bear the cost of soliciting proxies from our Class B Stockholders. It is planned that the solicitation will be initially by mail, but proxies may also be solicited by our employees. These persons will receive no additional compensation for such services, but will be reimbursed for reasonable out-of-pocket expenses. Arrangements will also be made with brokerage houses and other custodians, nominees and fiduciaries for the forwarding of solicitation materials to the beneficial owners of shares held of record by these persons, and we will reimburse them for their reasonable out-of-pocket expenses. The cost of such solicitation, estimated to be approximately $5,000, will be borne by us.

What is the quorum requirement of the Meeting?

A quorum for the consideration of Matters 1, 2, 3, 4 and 5 shall be Class B Stockholders present in person or by proxy representing not less than a majority of the outstanding Class B Stock.

What are broker non-votes?

Broker non-votes occur when holders of record, such as banks and brokers holding shares on behalf of beneficial owners, do not receive voting instructions from the beneficial holders at least ten days before the Meeting. Broker non-votes and abstentions will not affect the outcome of the matters being voted on at the Meeting, assuming that a quorum is obtained.

What vote is required to approve each matter?

Matter No. 1, election of directors. The election of each of the directors nominated requires the affirmative vote, in person or by proxy, of a simple majority of the Class B Stock voted at the Meeting if a quorum, or a majority of the Class B Stock, is present.

Matter No. 2, appointment of auditors. The ratification of the appointment of the auditors for 2026 and the authorization of the Audit Committee to fix the auditors’ remuneration requires the affirmative vote, in person or by proxy, of a simple majority of the Class B Stock voted at the Meeting if a quorum, or a majority of the Class B Stock, is present.

Matter No. 3, the approval or disapproval, in an advisory (non-binding) vote, of the Company’s executive compensation may be approved or disapproved by the vote, in person or by proxy, of a simple majority of the Class B Stock voted at the Meeting, if a quorum, or a majority of the Class B Stock, is present.

Matter No. 4, the approval or disapproval, in an advisory (non-binding) vote, that a shareholder vote to approve or disapprove executive compensation (Matter 3 above) should occur every 1, 2 or 3 years. A simple majority of the Class B Stock voted at the Meeting if a quorum, or a majority of the Class B Stock, is present is sufficient to adopt the advisory proposal that a shareholder vote to approve or disapprove executive compensation should occur every 1, 2 or 3 years;

Matter No. 5, the approval or disapproval of the Company’s Amended and Restated Certificate of Incorporation may be approved or disapproved by the vote, in person or by proxy, of a majority of the Class B Stock voted at the Meeting, if a quorum, or a majority of the Class B Stock, is present.

Mr. A.G. Lowenthal, our Chairman of the Board of Directors, owns 97.5% of the Class B Stock and intends to vote all of such Class B Stock in favor of each of Matters 1, 2, 3 and 5, and intends to vote for 3 years with respect to Matter 4. As a result, each of the matters before the Meeting is expected to be approved. See “Security Ownership of Certain Beneficial Owners and Management.”

Who can attend the Meeting?

All registered Class A Stockholders, Class B Stockholders, their duly appointed representatives, our directors and officers, and our auditors are entitled to listen to and view the Meeting and have an opportunity to submit questions for consideration and response at or after the Meeting by emailing info@opco.com.

What does it mean if I get more than one proxy card?

It means that you own shares in more than one account. You should vote the shares on each of your proxy cards.

I own my shares indirectly through my broker, bank, or other nominee, and I receive multiple copies of the proxy materials, and other mailings because more than one person in my household is a beneficial owner. How can I change the number of copies of these mailings that are sent to my household?

If you and other members of your household are beneficial owners, you may eliminate this duplication of mailings by contacting your broker, bank, or other nominee. Duplicate mailings in most cases are wasteful for us and inconvenient for you, and we encourage you to eliminate them whenever you can. If you have eliminated duplicate mailings, but for any reason would like to resume them, you must contact your broker, bank, or other nominee.

Multiple stockholders live in my household, and together we received only one copy of these proxy materials. How can I obtain my own separate copy of this document for the Meeting?

You may download them from our Internet web site, www.oppenheimer.com (click on the link to the About Us/Investor Relations page). If you want copies mailed to you and are a beneficial owner, you must request them from your broker, bank, or other nominee. If you want copies mailed to you and are a stockholder of record, we will mail them promptly if you request them from our corporate office by phone at (212) 668-8000, by email at info@opco.com, through our website at https://www.oppenheimer.com/about-us/investor-relations or by mail to 85 Broad Street, New York, NY 10004, Attention: Secretary. We cannot guarantee you will receive mailed copies before the Meeting.

Where can I find the voting results of the Meeting?

We are required to file the voting results in a Current Report on Form 8-K which you can find within four business days of the Meeting on the EDGAR website at www.sec.gov or upon request to our corporate office by phone at (212) 668-8000, by email at info@opco.com, through our website at https://www.oppenheimer.com/about-us/investor-relations, by mail to 85 Broad Street, New York, NY 10004, Attention: Secretary, or by accessing the PDF copy filed with the SEC at www.sec.gov.

Generally, Class A Stockholders are afforded the opportunity to receive notices of all meetings of stockholders and to attend such meetings. However, due to the virtual nature of the Meeting, Class A

Stockholders will not be able to speak at the Meeting and must submit questions by email to info@opco.com. Class A Stockholders are also afforded the opportunity to obtain all informational documentation sent to the Class B Stockholders.

Class B Stockholders are entitled to one vote for each share of Class B Stock held as of the record date for the Meeting.

Appointment and Revocation of Proxies

Each of Albert G. Lowenthal and Dennis P. McNamara (the “Management Nominees”) has been appointed by the Board of Directors to serve as a proxy for the Class B Stockholders at the Meeting.

Class B Stockholders have the right to appoint persons, other than the Management Nominees, who need not be stockholders, to represent them at the Meeting. To exercise this right, the Class B Stockholder may insert the name of the desired person in the blank space provided in the form of proxy accompanying this proxy statement or may submit another form of proxy.

In order to be used at the Meeting, proxies must be deposited with either our transfer agent, Computershare Inc., at its address at Computershare Investor Services, PO Box 43101, Providence, Rhode Island 02940-5067, no later than the last business day preceding the day of the Meeting or with our Secretary on the day of the Meeting, prior to the commencement of the Meeting, by emailing it to info@opco.com, Attention: Secretary.

Each form of proxy confers discretionary authority with respect to amendments or variations to matters identified in the Notice of Meeting to which the proxy relates and other matters which may properly come before the Meeting. Management knows of no matters to come before the Meeting other than the matters referred to in the Notice of Meeting. However, if matters which are not known to management should properly come before the Meeting, the proxies will be voted on such matters in accordance with the best judgment of the person or persons voting the proxies.

A Class B Stockholder who has given a proxy has the power to revoke it prior to the commencement of the Meeting by depositing an instrument in writing executed by the Class B Stockholder or by the stockholder’s attorney-in-fact either with our transfer agent at any time up to and including the last business day preceding the day of the Meeting, or any adjournments thereof, or depositing it with our Secretary on the day of the Meeting, or any adjournments thereof, prior to the commencement of the Meeting, by emailing it to info@opco.com, Attention: Secretary, or in any other manner permitted by law.

Our Amended and Restated By-laws dated as of February 25, 2021 (the “Bylaws”) provide that our Board of Directors consists of no less than three and no more than eleven directors to be elected annually. Our Board of Directors currently consists of nine directors. The term of office for each director is from the date of the meeting of stockholders at which the director is elected until the close of the next annual meeting of stockholders or until his or her successor is duly elected or appointed, unless his or her office is earlier vacated, in accordance with our Bylaws.

The Nominating and Corporate Governance Committee of the Board has recommended, and the Board of Directors has determined, that nine directors are to be elected at the Meeting. Management does not contemplate that any of the nominees named below will be unable to serve as a director, but, if such an event should occur for any reason prior to the Meeting, the Management Nominees reserve the right to vote for another nominee or nominees in their discretion.

The following sets out information with respect to the proposed nominees for election as directors as recommended by the Nominating and Corporate Governance Committee and approved by the Board of Directors, in accordance with the Nominating and Corporate Governance Committee Charter (available at www.oppenheimer.com). The Nominating and Corporate Governance Committee has reported that it is satisfied that each of the nominees is fully able and fully committed to serve the best interests of our stockholders. The election of the persons nominated for election as directors requires the affirmative vote of a simple majority of the Class B Stock voted at the Meeting.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR EACH OF THE PERSONS NOMINATED FOR ELECTION AS A DIRECTOR.

Executive Officers

Our executive officers consist of Mr. A.G. Lowenthal, our Chairman, and Mr. R.S. Lowenthal, our Chief Executive Officer, each of whose background is described above, and Mr. Watkins, our Chief Financial Officer and principal financial and accounting officer, whose background is described below.

Brad M. Watkins

Age: 44

Mr. Watkins joined the Company as Executive Vice President and Chief Financial Officer of Oppenheimer & Co. Inc. and Oppenheimer Holdings Inc. on August 1, 2022. He also serves on a number of the Company’s committees, including the Management, Risk Management, Market Risk, Credit Risk, Liquidity Risk, Product Oversight and New Product Committees. Prior to joining the Company, Mr. Watkins was a partner at KPMG, where he worked for approximately 19 years in their Financial Services audit practice serving a multitude of clients, including broker-dealers and other financial institutions. He is a certified public accountant with extensive experience with U.S. GAAP and IFRS requirements, SEC reporting matters and broker-dealer regulatory compliance. Mr. Watkins graduated from New York University’s Stern School of Business with a Bachelor of Science in Accounting in 2003.

In February 2025, the Company announced that Mr. A.G. Lowenthal would step down as Chief Executive Officer of the Company and its primary operating subsidiary, Oppenheimer & Co. Inc. (“Oppenheimer”), effective at the close of the 2025 Annual Meeting of Stockholders. Mr. A.G. Lowenthal has continued in his role as Chairman of the Company and was named Executive Chairman of Oppenheimer. Mr. R.S. Lowenthal, formerly President and Head of Investment Banking of Oppenheimer, was appointed as Chief Executive Officer of the Company and Oppenheimer, effective May 6, 2025. The Board of Directors, most prominently through the work of the Nominating and Corporate Governance Committee, oversaw the transition process and was significantly involved in evaluating and determining that Mr. R.S. Lowenthal was the best candidate to assume the role of Chief Executive Officer, commencing at the conclusion of the Meeting.

Board Leadership Structure

The Board believes that Mr. A.G. Lowenthal, Chairman and former Chief Executive Officer, is best situated to serve as Chairman of the Board because he is the director most familiar with the Company’s business strategy, history and capabilities, and most capable of effectively identifying strategic priorities and leading the discussion and execution of strategy. Independent directors and management add different perspectives and roles in strategy development. Additionally, the Company’s independent directors bring experience, oversight and expertise from outside the Company and, in some cases, outside the industry, and the Chief Executive Officer brings Company-specific and industry-specific experience and expertise.

One of the key responsibilities of the Board of Directors is to develop strategic direction and hold management accountable for the execution of strategy once it is developed. The Board believes an independent Lead Director having the duties described below is in the best interest of stockholders because it provides the appropriate balance between strategy development and independent oversight of management for our Company. The Board’s administration of its oversight function is described in greater detail below under “Risk Management.”

The Board of Directors is responsible for oversight of succession planning for senior executives in the Company. Consequently, succession planning has been an ongoing key topic of discussion for many years. The Board’s succession planning processes are long-term and supported by the Board’s committee structure.

Lead Director

Mr. P. Friedman, an independent director who serves on the Compensation, Compliance and Nominating and Corporate Governance Committees, was selected by the Board to serve as the Lead Director for all meetings of the independent directors held in executive session. The role of the Lead Director is to assure the independence of the Board from management. The Lead Director has the responsibility of

presiding at all executive sessions of the Board, consulting with the Chairman and the Chief Executive Officer on Board and committee meeting agendas, acting as a liaison between management and the non-management directors, including maintaining frequent contact with the Chairman and the Chief Executive Officer and advising them on the efficiency and effectiveness of Board meetings, and facilitating teamwork and communication between the independent directors and management, as well as additional responsibilities that may be assigned to the Lead Director by the Board from time to time.

Executive Sessions

Pursuant to the Company’s Corporate Governance Guidelines, independent directors of the Board meet on a regularly scheduled basis and otherwise as the independent directors determine without the presence of management. The Lead Director chairs these sessions. To ensure strong communication with the Chief Executive Officer, the independent directors, or the Lead Director representing the independent directors, may meet with the Chief Executive Officer and/or the Chairman alone as the independent directors determine.

Board of Directors and Committee Meetings Held

During 2025, the following numbers of Board and committee meetings were held:

	Board of Directors					6
	Audit Committee					5
	Compensation Committee					2
	Compliance Committee					4
	Nominating and Corporate Governance Committee					2

Meeting Attendance

Pursuant to the Company’s policies on meeting attendance, all directors should strive to attend all meetings of the Board and the committees of which they are members. Last year there were six meetings of the Board. We are pleased that all directors attended 100% of the meetings of the Board and all meetings of committees of the Board in 2025 during the periods in which they each served as a director.

In addition to participation at Board and committee meetings, our directors discharge their responsibilities throughout the year through personal meetings and other communications, including considerable telephone contact with the Chairman, Chief Executive Officer and other members of senior management and each other regarding matters of interest and concern to the Company. It is our policy that our directors attend our stockholders meetings and, at the last Annual Meeting of Stockholders held virtually on May 5, 2025, all of the directors nominated attended.

The Board met in-person throughout 2025. The present intention of the Board is to continue to meet in person in 2026, subject to events necessitating remote meetings. Certain committee meetings of the Board may also be held virtually.

The Company’s most recent Annual Meeting of Stockholders was held on May 5, 2025 in virtual format using technology supplied by our transfer agent, Computershare Inc.

Throughout 2025, most employees worked under a hybrid arrangement that recognizes the benefits of collaboration and hands-on training associated with in-person engagement, along with the importance of flexibility associated with a work-from-home/remote option. Our ability to avoid significant business disruptions is reliant on the continued ability to support our employees that continue to work remotely. To date, there have been no significant disruptions to our business or control processes as a result of this dispersion of employees. The Company believes that in-person engagement at the workplace provides important benefits that are largely lost through remote work, and will continue to encourage employees to work in the office on a regular basis while continuing to provide some flexibility through an ability to work on a remote basis.

Risk Management

The Board, as a whole and also at the committee level, has an active role in overseeing the management of the Company’s strategic, operational, financial and compliance risks, including risks related to cybersecurity. The Board regularly reviews information regarding the Company’s credit, liquidity, cybersecurity systems, and operations, as well as the risks associated with each. The Company’s Compensation Committee is responsible for overseeing the Company’s executive compensation arrangements and assuring that financial incentives for management and employees are appropriate and mitigate against, rather than encourage, employees taking excessive risk exposure with firm capital. Please see “Compensation Policies and Risk” for further information. The Audit Committee oversees management of operational and financial risks. The Company also has a number of internal risk-oversight committees and functions. The Company’s Compliance Committee is responsible for overseeing the Company’s compliance function and the management of compliance and regulatory risk. The Company’s internal Risk Management Committee (composed of management employees) is charged with assessing, reviewing and monitoring the risk environment in which the Company operates, including risks related to cybersecurity, and reports its findings and considerations to the Audit Committee at each regularly scheduled quarterly meeting and more frequently, as needed. The Nominating and Corporate Governance Committee manages risks associated with the governance of the Company, including the composition, responsibilities and independence of the Board of Directors and ethical and regulatory issues, including conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board of Directors is regularly informed through committee reports about such risks, including receiving updates and reports from the Company’s Chief Information Officer and his staff regarding risks related to cybersecurity.

Corporate Governance

Our Class A Stock is listed on the New York Stock Exchange (“NYSE”). We are subject to the corporate governance policies and requirements of the NYSE, the applicable rules of the Securities and Exchange Commission (the “SEC”), the provisions of the Sarbanes-Oxley Act of 2002 and the applicable rules of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“Dodd-Frank”).

Our Nominating and Corporate Governance Committee, Compensation Committee, Audit Committee, Compliance Committee and our Board of Directors continue to monitor regulatory changes and best practices in corporate governance and consider amendments to our practices and policies as appropriate.

Our Corporate Governance Guidelines, and all committee charters, as well as our Code of Conduct and Business Ethics for Directors, Officers and Employees (“Code of Conduct”) and our Financial Whistleblower Policy (“Whistleblower Policy”), are posted on our website at www.oppenheimer.com.

Board of Directors

The fundamental responsibility of the Board of Directors is to oversee the management of our business with a view to maximizing stockholder value and ensuring that corporate conduct occurs in a legal and ethical manner through a system of corporate governance and internal controls appropriate to our business. The Board of Directors has adopted and, pursuant to recommendations from the Nominating and Corporate Governance Committee, updates from time to time a statement of Corporate Governance Guidelines to which it adheres. We have a Code of Conduct which is posted on our website at www.oppenheimer.com. No waivers were granted in 2025 or to date in 2026 under the Code of Conduct for any directors, officers or employees.

In fulfilling its mandate, the Board’s responsibilities include:

•

monitoring and overseeing the Company’s strategic planning;

•

monitoring the performance of the Company’s business, evaluating opportunities and risks, and controlling risk;

•

monitoring systems for audit, internal control and information management;

•

monitoring the performance of senior management of the Company, including the Chief Executive Officer, and delegating responsibility for the day-to-day operations of the Company to senior management;

•

satisfying itself as to the integrity of the Chief Executive Officer and other senior management and ensuring that they create a culture of integrity throughout the Company;

•

overseeing the monitoring of compliance with applicable regulatory requirements, as well as assessing reports related to the Company’s compliance and supervision programs, reviewing findings and communications from regulators, including reports related to regulatory examinations, and assessing the adequacy of the Company’s responses thereto;

•

succession planning for senior management and directors;

•

remuneration of the executive officers and reviewing the general compensation policies of the Company;

•

governance, including composition and effectiveness of the Board;

•

monitoring compliance with the Company’s legal and regulatory compliance policies and related legal and regulatory requirements of the Company’s subsidiaries;

•

monitoring compliance with the Code of Conduct adopted by the Board;

•

reviewing the implementation of significant regulatory initiatives, including those related to anti-money laundering; and

•

receiving regular updates on technology initiatives, including those related to cybersecurity.

Director Independence

Seven of the Company’s nine directors are independent as required by the NYSE Corporate Governance Rules. To be considered independent under these rules, the Board of Directors must determine that a director has no direct or indirect material relationship with the Company. The Board of Directors determined that Mr. Behrens, Mr. Dwyer, Mr. Friedman, Ms. Glasser, Ms. Kanter, Mr. Roth and Ms. Spaulding are independent directors and that Mr. A.G. Lowenthal, Chairman of the Board of Directors, and Mr. R.S. Lowenthal, Chief Executive Officer of the Company and son of Mr. A.G. Lowenthal, are not independent.

The Board of Directors has not adopted formal categorical standards to assist in determining independence. The Board has considered the types of relationships that could be relevant to the independence of a director of the Company. These relationships are described in Schedule B to the Company’s Corporate Governance Guidelines, which guidelines are posted on our website at www.oppenheimer.com. The Board of Directors has considered the relationship of each director and has made a determination that seven of the Company’s current nine directors are independent at this time and that seven of the Company’s nine nominees are independent.

At each regular Board and Audit Committee meeting, the independent directors are afforded an opportunity to meet in the absence of management. During 2025, five of the six board meetings were regular meetings. Additionally, at regular meetings of the Audit Committee (four regular meetings annually), the members of the Audit Committee, all of whom are independent, are afforded the opportunity to meet with the independent auditors and the managers of the Company’s Internal Audit Group in the absence of management. Members of the Compliance Committee, all of whom are independent, are afforded the opportunity to meet with the managers of the Company’s compliance functions in the absence of management.

The independent directors and the directors that are not independent understand the need for directors to be independent-minded and to assess and question management initiatives and recommendations from an independent perspective. The Board of Directors’ Lead Director, Mr. Friedman, is an independent director who, among other things, chairs sessions of the independent directors.

Orientation and Continuing Education

The Nominating and Corporate Governance Committee of the Board of Directors, as required by its charter, is responsible for the orientation of new directors to our business and overseeing the continuing education needs of all directors.

The Board of Directors believes that the Company is best served by a board of directors that functions independently of management and that is informed and engaged. The Board of Directors encourages the directors to maintain the skill and knowledge necessary to meet their obligations as directors. Commencing in 2026, the Company and each director obtained a membership in the National Association of Corporate Directors which provides the opportunity for significant in-person and virtual director education sessions. Our directors understand the need to maintain their knowledge and skills and avail themselves of director education literature and programs.

Board and Committee Assessments

The Board conducts a self-evaluation annually to determine whether it and its Committees are functioning effectively. The Nominating and Corporate Governance Committee develops the process for and oversees this annual self-evaluation.

Board Committees

The Board has established an Audit Committee, a Compensation Committee, a Compliance Committee and a Nominating and Corporate Governance Committee. The Audit, Compensation, Compliance and Nominating and Corporate Governance Committees are composed entirely of independent directors, as defined in the NYSE Listed Company Manual and the Company’s Corporate Governance Guidelines. The charters of each committee are available on the Company’s website at www.oppenheimer.com.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee Charter, a copy of which is posted on our website at www.oppenheimer.com, provides that the Nominating and Corporate Governance Committee is responsible for ensuring that our Board of Directors is composed of directors who are fully able and fully committed to serve the best interests of our stockholders. Factors considered by the Nominating and Corporate Governance Committee in assessing director performance and, when needed, recruiting new directors, include skills, character, judgment, experience, ethics, integrity, diversity and compatibility with the existing Board of Directors.

The Nominating and Corporate Governance Committee currently has five members, all of whom are independent. The duties of this Committee are set out as follows:

•

determine the qualifications, qualities, skills and other expertise required to be a director, and develop, and recommend to the Board for its approval, criteria to be considered in selecting nominees for director;

•

identify and screen qualified individuals for Board positions;

•

recommend additions to the Board and persons to fill vacancies on the Board;

•

review the Board’s committee structure and composition and recommend directors to serve as committee members;

•

ensure that the Board is kept up to date with respect to the regulatory environment relevant to governance issues;

•

maintain an orientation program for new directors and oversee the continuing education needs of directors;

•

oversee the evaluation of the Board and management;

•

make recommendations to assure the efficiency of Board meetings;

•

develop, review and make recommendations with respect to our Corporate Governance Guidelines;

•

oversee the Company’s corporate governance policies, practices and procedures;

•

review and approve governance reports for publication in our management proxy statement and Annual Report on Form 10-K; and

•

annually review the Nominating and Corporate Governance Committee’s Charter and recommend and make changes thereto as required.

The Nominating and Corporate Governance Committee will give appropriate consideration to board nominees recommended by Class B Stockholders. Nominees recommended by Class B Stockholders will be evaluated in the same manner as other nominees. Class B Stockholders who wish to submit nominees for director for consideration by the Nominating and Corporate Governance Committee for election at our next Annual Meeting of Stockholders to be held in 2027 may do so by submitting in writing such nominee’s name, in compliance with the procedures and along with the other information required by our Bylaws and Regulation 14A under the Exchange Act (including such nominee’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected), to our Secretary, at 85 Broad Street, 22nd Floor, New York, NY 10004 within the time frames set forth under the heading “Stockholder Proposals.”

The Nominating and Corporate Governance Committee is responsible for the recruitment of persons for Board positions, and for making recommendations to the Board for the appointment of directors to fill vacancies on the Board and for nominees for the slate of directors to stand for election by vote of the Class B Stockholders at the Annual Meeting of Stockholders. In recruiting directors, and when considering the performance of incumbent directors when determining whether to recommend them for re-election, the Nominating and Corporate Governance Committee considers:

•

judgment, character, expertise, skills and knowledge useful to the oversight of the Company’s business;

•

proven track record of sound business judgment and good business decisions;

•

specific knowledge and experience to support the development and/or implementation of business strategy;

•

business or other relevant experience, including, without limitation, understanding of financial and accounting principles and general financial literacy, appropriate knowledge of business and industry issues, prior work for public companies and previous Board experience;

•

availability for Board and committee work;

•

communication and influencing skills;

•

reputation amongst peers;

•

existing relationship(s) with the Company’s management;

•

demonstrated integrity and high ethical standards;

•

diversity of viewpoints, backgrounds, experiences and other demographics; and

•

the extent to which the interplay of the individual’s expertise, skills, knowledge and experience with that of other members of the Board will build a board that is effective, collegial and responsive to the needs of the Company.

The Nominating and Corporate Governance Committee is also responsible for initially assessing, against the Company’s standards for directors’ independence, whether a candidate would be independent and whether continuing directors continue to be independent and advising the Board of that assessment.

Notes to 2025 Director Compensation Table

(1)

In the year ending December 31, 2025 we paid directors’ fees as follows:

	Annual Retainer Fee			$50,000

	Committee Chairmen, except Audit			$15,000

(2)

The values of restricted stock awards (granted under the Company’s 2024 Incentive Plan) represent the grant date fair value of awards granted in the fiscal year. The underlying assumptions and methodology used to value our stock awards are described in note 17 to our consolidated financial statements for the year ended December 31, 2025 included in our Annual Report on Form 10-K for the year ended December 31, 2025 which is available on our web site at www.oppenheimer.com or in paper on request. Details of restricted stock awards held by the Named Executives appear in the “Outstanding Equity Awards Table” and notes thereto, appearing below. Details of options and restricted stock held by our non-employee directors appear below under “Director Stock-based Compensation.”

(3)

Non-employee directors receive annual stock awards of restricted Class A Stock as determined by the full Board of Directors (1,500 restricted shares each on January 29, 2025 and 1,400 shares on February 26, 2026) which vest as follows: 25% six months from the initial grant date and 25% on each subsequent one year anniversary of the grant date. Directors are expected to accumulate and hold at least 6,000 shares of the Company’s Class A Stock and have three years after joining the Board of Directors to achieve that position.

In 2025, the directors were paid directors’ fees in cash of $705,000 in the aggregate. Directors are reimbursed for travel and related expenses incurred in attending board and committee meetings. The directors who are not our employees are also entitled to the grant of stock awards under the Company’s 2024 Incentive Plan, which was adopted effective as of March 1, 2024 and ratified by our stockholders on May 6, 2024. Reference is made to the table under “Director Stock-based Compensation” below. Directors who are our employees are not entitled to receive compensation for their service as directors.

The Company has not made contributions to any tax exempt organizations in which an independent director serves as an executive officer.

We operate in a challenging marketplace in which our success depends upon, among other things, our ability to attract and retain non-employee directors of the highest caliber. The Board believes that we must offer a competitive non-employee director compensation program if we are to successfully attract and retain the best possible candidates for these important positions of responsibility.

Director Stock-based Compensation

Under its charter, the Compensation Committee is required to discharge the Board of Directors’ responsibilities relating to compensation of our senior executive officers and to report on its practices to our stockholders in our annual proxy statement.

MATTER NO. 3

ADVISORY (NON-BINDING) VOTE ON EXECUTIVE COMPENSATION

In response to the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Section 14A of the Exchange Act, we are providing Class B Stockholders with an opportunity to cast an advisory (non-binding) vote on the compensation of our named executive officers identified in the “Summary Compensation Table” (“Named Executives”, commonly referred to as “say on pay” vote). Your vote is advisory and will not be binding on our Board of Directors. However, the Compensation Committee will take into account the outcome of the vote when making future executive compensation recommendations. It was determined at our 2023 Annual Meeting that this advisory vote take place every three years. The advisory votes that took place at our 2011, 2014, 2017, 2020 and 2023 Annual Meetings endorsed the referenced compensation. You are also being asked to vote on the frequency of this advisory vote at the Meeting (See Matter No. 4).

Our compensation policy is designed to recruit, motivate, reward and retain the high performing executive talent required to create superior long-term stockholder returns; reward executives for short-term performance, as well as growth in enterprise value over the long-term; provide a competitive compensation package relative to peers and competitors; and ensure effective utilization and development of talent by employing appropriate management processes, such as performance appraisal and management development.

Stockholders are encouraged to read the Compensation Discussion and Analysis (“CD&A”) section of this proxy statement, which describes our compensation policies and practices. The policies and practices described in the CD&A provide a compensation framework which enables us to retain and appropriately reward the executive officers that we believe are critical to our long-term success, while linking that compensation to our corporate objectives and performance.

For example:

•

our Named Executives do not generally have employment agreements;

•

our Named Executives do not receive supplemental retirement benefits;

•

other than access to two parking spaces, our Named Executives do not receive any perquisites that are not generally available to all employees;

•

our incentive compensation is reviewed annually by the Compensation Committee to ensure that we are not encouraging undue risk-taking and we are aligning executive compensation with the strategic objectives and performance of the Company;

•

our Chief Executive Officer’s annual salary and incentive compensation is established by the Compensation Committee which is composed of independent directors;

•

a substantial portion of our Chief Executive Officer’s compensation is driven by performance goals which are established annually by the Compensation Committee from a broad array of financial, performance and strategic parameters; and

•

we have approved a compensation recovery policy which provides for the recovery, under certain circumstances, of all of the incentive compensation received by our executive officers (currently our Chairman, Chief Executive Officer and Chief Financial Officer), as well as cash bonuses and any profits realized from the sale of securities of the Company during the twelve month period following the issuance in the case of a restatement of our financial statements, the unvested incentive compensation of other officers and employees designated by the Compensation Committee received during the three fiscal years prior to a restatement of our financial statements, and a portion of the unvested incentive compensation paid to our executive officers and other designated officers and employees in the case of material misconduct or other violative behavior.

This Matter No. 3, commonly known as a “say on pay” proposal, gives you, as a Class B Stockholder, an opportunity to endorse or not endorse the compensation we pay to our Named Executives on an advisory basis, pursuant to the following resolution:

RESOLVED THAT:

The compensation paid to Oppenheimer Holding Inc.’s Named Executives, as disclosed pursuant to the Securities and Exchange Commission’s compensation disclosure rules, including the Compensation Discussion and Analysis, compensation tables, and narrative discussion set forth on pages 38-55 of this Proxy Statement, is hereby approved.

To be effective, this resolution must be passed by the affirmative vote of a simple majority of the votes cast by the Class B Stockholders at the meeting. Mr. A.G. Lowenthal owns 97.5% of the Class B Stock and has informed the Company that he intends to vote all of such Class B Stock in favor of the proposal. See “Security Ownership of Certain Beneficial Owners and Management.”

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVES AS DISCLOSED IN THIS PROXY STATEMENT.

MATTER NO. 4

ADVISORY (NON-BINDING) VOTE ON THE FREQUENCY OF AN ADVISORY VOTE
ON EXECUTIVE COMPENSATION

In response to the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Section 14A of the Exchange Act, we are providing Class B Stockholders with an opportunity to cast an advisory (non-binding) vote on how frequently we should seek an advisory vote on the compensation of our Named Executives, commonly referred to as a “say on pay” vote, as provided in Matter No. 3.

Dodd-Frank and Section 14A of the Exchange Act requires us, not less frequency than once every three years, to submit a proposal allowing our Class B Stockholders to vote, in an advisory, non-binding vote, on whether the frequency of a vote on executive compensation will occur every 1, 2, or 3 years. As a Class B Stockholder of the Company, you are being provided the opportunity to vote on the frequency of the vote on executive compensation.

Your vote is advisory and will not be binding upon our Board of Directors. However, the Compensation Committee will take into account the outcome of the vote when considering the frequency of submitting to Class B Stockholders a resolution to afford Class B Stockholders the opportunity to vote on executive compensation.

The Company’s Board of Directors recommends that Class B Stockholders vote “FOR” the resolution to have a vote on executive compensation every three years. The Company’s compensation programs and policies have remained consistent over many years and, therefore, your Board does not believe that a more frequent vote on executive compensation would provide a benefit.

The accompanying form of proxy provides for four choices (every 1, 2 or 3 years or abstain). Class B Stockholders are voting on one of these periods, and are not voting to approve or disapprove the Company’s recommendation.

The frequency of the Class B Stockholder vote on executive compensation (every 1, 2 or 3 years) will be determined by a plurality of votes cast “FOR” the year receiving the highest number of votes, even if such votes do not constitute a majority. Abstentions will not be counted as votes cast either for or against the proposal. Mr. A.G. Lowenthal owns 97.5% of the Class B Stock and has informed the Company that he intends to vote all such Class B Stock in favor of holding a vote on executive compensation every three years. See “Security Ownership of Certain Beneficial Owners and Management”.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE “3 YEAR” FREQUENCY OPTION ON FUTURE ADVISORY VOTES ON EXECUTIVE COMPENSATION.

MATTER NO. 5

APPROVAL OF AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

General

After careful consideration, the Board of Directors has unanimously approved, and recommends that stockholders approve, the amendment and restatement of our Certificate of Incorporation (the “Current Charter”), as described below and as set forth in Appendix 1 (the “Amended and Restated Charter”). The Board of Directors believes it is in the Company’s best interest to take the opportunity to amend and restate our Current Charter to provide for the indemnification of the Company’s directors and officers to the extent permitted by the DGCL, to remove provisions that are no longer relevant, and to make certain non-substantive clarifying enhancements.

Summary of Changes

The Amended and Restated Charter reflects the following principal changes:

Director and Officer Indemnification. The Amended and Restated Charter provides for indemnification and advancement of expenses to the Company’s directors and officers to the fullest extent permitted by the DGCL (as it may be amended from time to time). The Board of Directors believes that the addition of this provision aligns our governance practices with those commonly adopted by other public companies, and supports the Company’s ability to attract and retain qualified directors and officers. Serving as a director or officer carries substantial risk of litigation and regulatory exposure, and the Board of Directors believes that it benefits the Company and its stockholders to ensure that our directors and officers can perform their duties independently and in the best interest of stockholders without undue concern about personal liability. Furthermore, the Board of Directors believes that the absence of such protections could discourage qualified directors and officers from serving in such roles due to potential exposure to personal liability and the risk that substantial expense may be incurred in defending lawsuits, regardless of their merit. The indemnification applies to directors and officers of the Company and, in certain circumstances, to individuals serving at the request of the Company in similar capacities for other entities, as set forth in the Amended and Restated Charter.

Irrelevant Provisions and Clarifying Language. In addition, certain provisions in our Current Charter are no longer applicable or require updates. These include outdated registered office information and references to the Company’s domestication over a decade ago. The Board believes it is in the best interest of the Company to revise the Current Charter to include clear, updated language and remove irrelevant provisions.

Timing and Effect of the Amended and Restated Charter

If the proposed Amended and Restated Charter is approved by our stockholders, it will become effective immediately upon its filing with the Secretary of State of the State of Delaware.

Vote Required for Approval

The approval of Matter No. 5 requires, pursuant to Section 242 of the DGCL, the affirmative vote of the stockholders holding a majority of the outstanding Class B Stock entitled to vote thereon. Mr. A.G. Lowenthal owns 97.5% of the Class B Stock and has informed the Company that he intends to vote all of such Class B Stock in favor of the proposal. See “Security Ownership of Certain Beneficial Owners and Management.”

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE TO APPROVE THE AMENDED AND RESTATED CHARTER.

EXECUTIVE COMPENSATION AND RELATED INFORMATION

2025 Company Performance

The U.S. economy in 2025 remained in growth mode, with real GDP growth around 2% — cooler than earlier years, yet clearly expansionary. Consumer spending moderated but held up, helped by easing inflation and real wage gains. With year over year gains on benchmark equity indexes, higher income participants continued to fuel consumer spending. Housing and other rate-sensitive sectors lagged, while investment tied to AI, energy, and infrastructure were particularly strong, with AI spending plans fueling optimism.

Inflation drifted lower toward 21∕2 – 3%, allowing the Federal Reserve to pivot from “higher for longer” to cautious late-year rate cuts. After an initial scare based on early tariff announcements from the new Administration, markets and equities rallied and credit spreads tightened well before policy easing began. The labor market cooled without any significant impact on the rate of unemployment, reinforcing the soft-landing narrative that dominated investor sentiment.

Higher tariffs impacted consumer prices, as well as the costs of goods going into supply chains. This cost pressure threatened to slow a growing economy, but ultimately led to little macro drag. For markets, 2025 was constructive: stocks delivered strong overall returns, led by large-cap tech and productivity-driven sectors, while IPOs, debt issuance, and M&A activity picked up as capital markets reopened. The year was less about acceleration and more about confidence returning — steady growth, falling inflation, and healthier financial conditions.

Mid-year momentum drove the U.S. Equity markets to record highs with the S&P 500 off its high but closing at 6845.5 (up 17.9%) at year-end. Markets were again led by the “Magnificent Seven” which were up by 22.7% in 2025 (contributing over 25% of the increase in the index). The other major averages, the Dow Jones Industrial Average and the NASDAQ Composite, reached 48,063.29 (up 14.9%) and 23,241.99 (up 21.1%), respectively. Both short-term and long-term U.S. Treasury yields declined, reflecting both Federal Reserve reductions in the overnight rate, as well as lower inflation, with unemployment remaining low (4.6%).

•

The Company made considerable progress in 2025 with our Wealth Management business significantly and positively impacting results. Although lower interest rates and lower balances reduced returns from our FDIC program, our Client Assets Under Management reached an all-time record at $55.2 billion, with Assets Under Administration also reaching a record high during the year, and ending with $143.3 billion at year-end.

•

We saw a meaningful pick-up in the revenues derived from our Capital Markets Division as transactional revenues increased in both Equities and Fixed Income, and we saw an increase in business from Investment Banking. The Company’s total revenues reached $1.638 billion, up 14.4%, driving earnings of $148.4 million or $14.13 per share up from $71.5 million or $6.91 per share in 2024.

•

Our book value reached $93.81 per share, with tangible book value reaching $76.78 per share. The operating results drove a significant increase in our share price. We maintained our regular quarterly dividend of $0.18 per share and declared a Special Dividend of $1.00 per share payable in early January 2026. We again reduced our share buy-backs, given the significant movement in our share price, re-purchasing only 46,292 shares at an average price of $64.36 per share for the entire year. Our shares outstanding at year-end were 10,487,240 and our shareholders’ equity reached an all-time record of $983.8 million.

•

In 2025, we continued to maintain a stable financial advisor headcount of 924 year-over-year despite some disappointing losses during the year. We continued to attract top-tier professionals despite intense competition across our industry. We began a new training program for recent graduates with a desire to pursue a career in Wealth Management, and the program was oversubscribed, permitting us to be particularly selective. In addition to advisors, we added branch managers in key markets to enhance growth.

•

Investment Banking revenues increased significantly in 2025 to $260.4 million, up more than 56.2% from $166.8 million in the prior year, with significantly increased activity from M&A

assignments and equity underwritings. Looking ahead to 2026, we anticipate a rebound in M&A activity, increased private credit opportunities, and an active IPO market, as well as continued demand for strategic advisory mandates.

•

We continued to add to our staff in public finance and saw a significant increase in public finance revenues, particularly in our participation in the underwriting of municipal bonds for major public issuers. Our public finance revenues reached $15.5 million for the year.

•

Our Institutional Equities business experienced significant growth in 2025, fueled by increased market volatility and the availability of both primary and secondary underwritings during the year. Notable trends, such as focusing on the AI related stocks, further amplified trading activity and commission growth in equities, options and convertible bonds. Our continued investment in Equity Research also played a critical role in driving our growth.

•

Our Fixed Income Division achieved record revenue growth, surpassing previous high-water marks and solidifying our position in the middle market. This success was driven by important investments in experienced individuals with specialized capabilities including the progress shown by our new distressed debt team, who joined in 2024.

The Compensation Committee and the Board of Directors believe that the policies and practices described in the following Compensation Discussion and Analysis provide a compensation framework which enables us to retain and appropriately reward the executive officers that we believe are critical to our long-term success, while linking that compensation to our corporate objectives and performance.

For example:

•

•

a substantial portion of our Chairman’s and our Chief Executive Officer’s compensation is variable and is normally driven by performance goals which are established annually by the Compensation Committee from a broad array of financial, performance and strategic parameters;

•

The Company remains committed to and actively engaged in the high-priority work of succession planning. In February 2025, the Company announced the transfer of the role of Chief Executive Officer from the Chairman to the President of the Company;

•

Base salaries paid to our Named Executives in 2025 were not increased from 2024 levels, except for an increase in our CEO’s base salary when he was appointed CEO in May; and

•

On February 6, 2026, the Compensation Committee awarded a total of 330,440 restricted shares of Class A Stock to our employees. Of these restricted shares, 138,685 shares will cliff vest three years from the date of the grant and 191,755 will cliff vest five years from the date of the grant. These awards will be expensed over the applicable three or five year vesting period.

The foregoing 2025 Company Performance and Compensation Highlights do not purport to be complete and are subject to, and qualified in their entirety by reference to, the Compensation Discussion and Analysis set forth below which, together with our Annual Report on Form 10-K for the year ended December 31, 2025, should be read in its entirety for a more complete understanding of our compensation policies, practices, and the compensation awarded to, earned by, or paid to our executive officers for 2025.

Compensation Discussion and Analysis

The following pages include our Compensation Discussion and Analysis.

Introduction

The following Compensation Discussion and Analysis describes the material elements of compensation for our named executive officers identified in the “Summary Compensation Table” (the “Named Executives”). The Compensation Committee, which is comprised entirely of independent directors, (i) develops, in consultation with the Chief Executive Officer, criteria related to incentive compensation for certain senior executives of the Company’s subsidiaries; (ii) reviews recommendations made by the Chief Executive Officer with respect to the salary, bonus and other compensation paid and provided to our senior management; and (iii) annually develops criteria related to incentive compensation for, and approves the compensation of, Mr. A.G. Lowenthal, our Chairman, and Mr. R.S. Lowenthal, our Chief Executive Officer.

Certain processes and procedures of the Compensation Committee are discussed below, including its role in dealing with the Chairman’s and the Chief Executive Officer’s compensation and the compensation of the other Named Executives. The Compensation Committee considers recommendations from the Chairman and from the Chief Executive Officer with respect to the compensation of the Named Executives (other than the Chairman or the Chief Executive Officer), as it does on compensation matters such as aggregate year-end allocation of incentive compensation and stock awards for other employees.
