Shareholders of Record and Beneficial Owners

If your shares are registered directly in your name on the books of the Company maintained with the Company’s transfer agent, Computershare, you are considered the “shareholder of record” of those shares and, if you request to receive a paper copy of them, the proxy materials will be mailed directly to you.

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the “beneficial owner” of shares held in street name (also called a “street name” holder), and, if you request to receive a paper copy of them, the proxy materials will be forwarded to you by your broker, bank or nominee. As the beneficial owner, you have the right to direct your broker, bank or nominee how to vote and are also invited to attend the 2025 Annual General Meeting. However, since you are not a shareholder of record, you may not vote these shares in person at the 2025 Annual General Meeting unless you bring with you a legal proxy duly executed by the shareholder of record. A legal proxy may be obtained from your broker, bank or other nominee.

VOTING OF PROXY, REVOCATION

A proxy that is properly executed, whether by using the Internet, by telephone or by mail, and not subsequently revoked will be voted in accordance with instructions contained therein. If no instructions are given with respect to the matters to be acted upon, proxies will be voted as follows: (1) for the election of Efstratios Georgios Arapoglou and Denis Petropoulos as directors, (2) for the approval of the Company’s 2024 audited financial statements, (3) for the appointment of Ernst & Young (Hellas) as the Company’s auditors for the fiscal year ending December 31, 2025 and to authorize the Audit Committee to set their remuneration, (4) for the approval of the directors’ remuneration, and (5) otherwise in accordance with the best judgment of the person or persons voting the proxy on any other matter properly brought before the 2025 Annual General Meeting.

Any shareholder who votes by completing and returning by mail the proxy card or voting instruction card or by using the Internet or by telephone, may revoke its proxy or change its vote at any time before it is voted at the 2025 Annual General Meeting by (A) delivering written notice to the Secretary of the Company of its revocation, (B) executing and delivering to the Secretary of the Company a later dated proxy by using the Internet, by telephone or by mail, or (C) by appearing in person at the 2025 Annual General Meeting and voting his, her or its shares in person.

EXPENSES OF SOLICITATION

Proxies are being solicited by the Board. The expenses of the preparation of proxy materials and the solicitation of proxies for the 2025 Annual General Meeting will be borne by the Company on behalf of the Board. In addition to solicitation by mail, proxies may be solicited in person, by telephone, telecopy, electronically, or other means, or by directors, officers and regular employees of the Company who will not receive additional compensation for such solicitations. If you choose to vote on the Internet, you are responsible for Internet access charges you may incur. D.F. King Co. Inc. has been engaged by the Company to assist in the solicitation of proxies for a fee of $17,500, plus their costs and expenses.

VOTING SECURITIES

Holders of record of the Company’s Common Shares as of the close of business on April 17, 2025 will be entitled to notice of, and to vote at, the 2025 Annual General Meeting or any adjournments thereof.

VASILEIOS PAPAGEORGIOU

CHIEF MARINE OFFICER

In addition, he heads the newbuilding section and technically led the recent successful large scale fleet expansion and renewal plan. For the past 20 years Mr. Papageorgiou has overseen the construction of more than 128 vessels of diverse type and range, amongst them DP Shuttle tankers and LNG vessels. He has an extended technical academic background, holding Bachelor of Science degrees in Naval Architecture and Marine Engineering and Master of Science degrees in Internal Combustion Engines and Management and Economics. Mr. Papageorgiou initiated his career 52 years ago, being employed for a period of 5 years in the Greek ship and repair yards of Skaramanga, Perama and Elefsis, being engaged in the supervision of ship repairs and new buildings. In 1976 and for a period of 4 years he worked for Chalkis Shipyard and Carras Shipping Co attending repairs and new buildings in Japan and Yugoslavia. In 1980, Mr. Papageorgiou joined Lloyd’s Register of Shipping initially as a junior Ship and Engine Surveyor in the Far East area (Korea, Japan, China, Hong Kong, Philippines). He was the first surveyor of Greek nationality of Lloyd’s Register supervising the construction of new buildings in Asia.

Successively, in 1990, Lloyd’s Register appointed him in the post of area Managing Director for the wider region of Greece, Balkans and Middle East, again a position held for the first time by a Greek citizen. Mr. Papageorgiou is an active participant in a wide range of technical committees.

CORPORATE GOVERNANCE

Board of Directors

Our business is managed under the direction of the Board, in accordance with the Companies Act 1981 of Bermuda, as amended (the “Companies Act”) and our Memorandum of Association and Bye-laws. Members of the Board are kept informed of our business through: discussions with the Chairman of the Board, the Chief Executive Officer and other members of our management team; the review of materials provided to directors; and, participation in meetings of the Board and its committees. In accordance with our Bye-laws, the Board has specified that the number of directors will be set at no less than five nor more than fifteen. We currently have nine directors on our Board. Under our Bye-laws, one third (or the number nearest to one third) of the Board (with the exception of any executive director) retires by rotation each year. The Bye-laws require that the one third of the directors to retire by rotation be those who have been in office longest since their last appointment or re-appointment. The Bye-laws specify that where the directors to retire have been in office for an equal length of time, those to retire are to be determined by lot (unless they agree otherwise among themselves). From the current directors, Messrs. Arapoglou and Petropoulos have been selected to stand for re-election at this year’s Annual General Meeting.

During the fiscal year ended December 31, 2024, the full Board held four meetings, one of which was by teleconference, two being held at Megaron Macedonia, 367 Syngrou Avenue, Athens, Greece, and one being held at Vouliagmeni. Each director attended all of the meetings of the Board and all of the meetings of committees of which such director was a member in 2024, except for one director, who attended at least 75% of such meetings.

Independence of Directors

The foundation for the Company’s corporate governance is the Board’s policy that a majority of the members of the Board should be independent. With the exception of the two Executive Directors (Messrs. Tsakos and Saroglou) and one Non-Executive Director (Mr. Jolliffe), the Board believes that each of the other incumbent directors (Messrs. Tommasino, Arapoglou, Mitropoulos and Petropoulos, Dr. Patrinos and Dr. Purnell) is independent under the standards established by the New York Stock Exchange (the “NYSE”) because none has a material relationship with the Company directly or indirectly or any relationship that would interfere with the exercise of their independent judgment as directors of the Company.

The Board made its determination of independence in accordance with its Corporate Governance Guidelines, which specify standards and a process for evaluating director independence. The Guidelines provide that:

•

A director cannot be independent if he or she fails to meet the objective requirements as to “independence” under the NYSE listing standards.

•

If a director meets the objective NYSE standards, he or she will be deemed independent, absent unusual circumstances, if in the current year and the past three years the director has had no related-party transaction or relationship with the Company or an “interlocking” relationship with another entity triggering disclosure under SEC rules.

•

If a director who meets the objective NYSE independence requirements either has had a disclosable transaction or relationship or the Corporate Governance, Nominating and Compensation Committee requests that the Board consider any other circumstances in determining the director’s independence, the Board will make a determination of the director’s independence.

To promote open discussion among the independent directors, those directors met three times in regularly scheduled executive sessions in 2024 without participation of the Company’s management and will continue to do so in 2025. Dr. Patrinos serves as the Presiding Director for purposes of these meetings.

Documents Establishing Our Corporate Governance

The Board and the Company’s management have engaged in an ongoing review of our corporate governance practices in order to oversee our compliance with the applicable corporate governance rules of the NYSE and the SEC.

The Company has adopted a number of key documents that are the foundation of its corporate governance, including:

•

a Code of Business Conduct and Ethics for Directors, Officers and Employees;

•

a Corporate Governance, Nominating and Compensation Committee Charter;

•

an Audit Committee Charter;

•

a Business Development and Capital Markets Committee Charter; and

•

an Environmental and Operational Committee Charter.

These documents, along with the Board’s Corporate Governance Guidelines and other important supplemental policies, are posted in the “Corporate Governance” section of the Tsakos Energy Navigation Limited website and may be viewed at http://www.tenn.gr. We will also provide any of these documents in hard copy upon the written request of a shareholder. Shareholders may direct their requests to the attention of Investor Relations, c/o George Saroglou or Paul Durham or Harrys Kosmatos, Tsakos Energy Navigation Limited, 367 Syngrou Avenue, 175 64 P. Faliro, Athens, Greece.

The Board has a long-standing commitment to sound and effective corporate governance practices. The Board’s Corporate Governance Guidelines address a number of important governance issues such as:

•

Selection and monitoring of the performance of the Company’s senior management;

•

Succession planning for the Company’s senior management;

•

Qualifications for membership on the Board;

•

Functioning of the Board, including the requirement for meetings of the independent directors; and

•

Standards and procedures for determining the independence of directors.

The Board believes that the Corporate Governance Guidelines and other governance documents meet current requirements and reflect a very high standard of corporate governance.

Committees of the Board

The Board has established an Audit Committee, a Corporate Governance, Nominating and Compensation Committee, a Business Development and Capital Markets Committee and an Operational, Safety and Environmental (“OSE”) Committee.

Audit Committee

The current members of the Audit Committee are Messrs. Tommasino, Arapoglou and Petropoulos, each of whom is an independent director. Mr. Tommasino serves as the Chairman of the committee. The Audit Committee is governed by a written charter, which is approved and adopted annually by the Board. The Board has determined that the continuing members of the Audit Committee meet the applicable independence requirements, and that all continuing members of the Audit Committee meet the requirement of being financially literate. The Audit Committee held three meetings during the fiscal year ended December 31, 2024. The Audit Committee is appointed by the Board and is responsible for, among other matters:

•

engaging the Company’s external and internal auditors;

•

approving in advance all audit and non-audit services provided by the auditors;

•

approving all fees paid to the auditors;

•

in conjunction with the full Board, approving the Company-wide risk management program; and

assessing whether the Company’s technical and commercial managers have effective procedures for managing risks.

The Board of Directors has determined that each of Messrs. Tommasino, Arapoglou and Petropoulos, whose biographical details are included herein, qualifies as an “audit committee financial expert” under current SEC regulations and each is independent in accordance with SEC rules and the listing standards of the NYSE.

Corporate Governance, Nominating and Compensation Committee

The current members of the Corporate Governance, Nominating and Compensation Committee are Messrs. Arapoglou, Mitropoulos, Tommasino, Petropoulos, Dr. Patrinos and Dr. Purnell, each of whom is an independent director. Dr. Patrinos serves as the Chairman of the committee. The Corporate Governance, Nominating and Compensation Committee is appointed by the Board and is responsible for:

•

developing and recommending to the Board corporate governance guidelines applicable to the company and keeping such guidelines under review;

•

overseeing the evaluation of the Board and management;

•

arranging for an annual performance evaluation of the committee and producing an annual report to the Board;

•

reviewing regularly the Board structure, size and composition and making recommendations to the Board with regard to any adjustments that are deemed necessary;

•

identifying and nominating candidates for the approval of the Board to fill Board vacancies as and when they arise;

•

implementing plans for succession, making recommendations to the Board for the continuation in service of an executive director and recommending directors who are retiring by rotation to be put forward for re-election;

•

producing an annual report on executive compensation as required by the SEC to be included in the Company’s annual proxy statement or annual report.

During 2024, there were three meetings of the Corporate Governance, Nominating and Compensation Committee.

Business Development and Capital Markets Committee

The current members of the Business Development and Capital Markets Committee are Messrs. Arapoglou, Jolliffe, Saroglou and Tsakos. Mr. Jolliffe is Chairman of the committee. The Business Development and Capital Markets Committee was established in 2014 for the purpose of overseeing the financial policies and activities of the Company and its subsidiaries relating to the Company’s capital structure and capital raising activities. The committee reviews and approves presentations to, and communications with, shareholders, financial analysts, and potential investors and oversees the establishment and maintenance of the Company’s relations with investment banks and financial institutions, as well as the development and expansion of the Company’s business, including the evaluation of strategic growth opportunities.

Operational, Safety and Environmental Committee

The current members of the Operational, Safety and Environmental Committee are Messrs. Jolliffe, Mitropoulos and Papageorgiou and Dr. Patrinos and Dr. Purnell. Mr. Mitropoulos is Chairman of the committee. The primary role of the OSE Committee is to draw the attention of the Board and the Company’s management to issues of concern regarding the safety and security of crew and vessels and the impact of the maritime industry on the environment, to provide an update on related legislation and technological innovations, and more specifically highlight areas in which the Company itself may play a more active role in being in the forefront of adopting operational procedures and technologies that will ensure maximum safety for crew and vessels and contribute to a better environment.

COMPENSATION DISCUSSION AND ANALYSIS

For the year ended December 31, 2024, the aggregate cash compensation of all of the members of the Board was $685,000 per the following annual fee schedule, which was approved by the shareholders of the Company on June 14, 2024:

No fees are paid for service, other than as Chairman, on the Corporate Governance and Nominating and Compensation Committee.

We do not provide benefits for directors upon termination of their service with us.

We do not propose any changes to the fee schedule set forth above for 2025. In Item No. 4, the Board recommends that the shareholders re-approve such fee schedule to be payable to non-management directors for the year ending December 31, 2025.

Management Company

Tsakos Energy Management Limited (“Tsakos Energy Management”), under its management agreement with us, provides overall executive and commercial management of our affairs in exchange for a monthly management fee. Under the terms of our management agreement with Tsakos Energy Management, we paid Tsakos Energy Management total management fees of $19.9 million in 2024, $19.5 million in 2023, and $20.2 million in 2022.

From the management fee we pay Tsakos Energy Management, Tsakos Energy Management in turn pays a management fee to Tsakos Shipping & Trading S.A. (“Tsakos Shipping” or “TST”)/Tsakos Shipmanagement S.A. (“TSM” formerly Tsakos Columbia Shipmanagement S.A.) for its services as technical manager of most of the vessels in our fleet. We prepay or reimburse our technical manager at cost for all vessel operating expenses payable by them in their capacity as technical manager of the fleet. In 2024, 2023 and 2022, an additional amount of $2.2 million, $1.2 million and $nil, respectively, was paid in fees directly by the Company to TST for additional services it provided and seafarers’ training. For additional services and seafarers’ training TSM charged the amount of $nil, $0.6 million and $1.9 million for 2024, 2023 and 2022, respectively.

In 2024, 2023 and 2022, we granted Tsakos Energy Management an incentive award of $7.0 million, $5.0 million and $1.0 million, respectively.

Our management agreement with Tsakos Energy Management was amended and restated on March 8, 2007 and has a term of ten years that renews annually. Tsakos Energy Management may terminate the management

agreement at any time upon not less than one year’s notice. In addition, either party may terminate the management agreement under certain circumstances, including the following:

•

certain events of bankruptcy or liquidation involving either party;

•

a material breach by either party; or

•

a failure by Tsakos Energy Management, for a continuous period of two months, materially to perform its duties because of certain events of force majeure.

Moreover, following a change in control of us, which would occur if at least one director were elected to our Board without having been recommended by our existing Board, Tsakos Energy Management may terminate the agreement on 10 business days’ notice. If Tsakos Energy Management terminates the agreement for this reason, then we would immediately be obligated to pay Tsakos Energy Management the present discounted value of all of the payments that would have otherwise been due under the management agreement up until June 30 of the tenth year following the date of termination plus the average of the incentive awards previously paid to Tsakos Energy Management multiplied by ten. Under these terms, therefore, a termination as of December 31, 2024 would have resulted in a payment of approximately $166.7 million. Under the terms of the Management Agreement between the Company and Tsakos Energy Management, the Company may terminate the agreement only under specific circumstances, such as breach of contract by the manager and change of control in the shareholding of the manager without the prior approval of the Company’s Board of Directors.

Management Compensation

Messrs. Tsakos, Saroglou, Durham, Kosmatos and Papageorgiou serve as Chief Executive Officer, President and Chief Operating Officer, Co-Chief Financial Officer and Chief Accounting Officer, Co-Chief Financial Officer and Chief Marine Officer, respectively. Such individuals are employees of Tsakos Energy Management, except for Mr. Papageorgiou who is an employee of Tsakos Shipping, and, except for the equity compensation discussed below under “Stock Compensation Plan” and the compensation paid to Mr. Papageorgiou for service on the OSE Committee, are not directly compensated by the Company. Although he is not a member of the Board, our Chief Marine Officer, Mr. Papageorgiou serves on the Operational, Safety and Environmental Committee and receives the same $10,000 per annum cash compensation for service on such committee as is paid to non-executive members of the Board serving thereon.

Employees

Tsakos Energy Navigation Limited has no salaried employees. All crew members are employed by the owning-company of the vessel on which they serve, except where the vessel may be on a bareboat charter-out, or where the vessels or the crewing thereof, are under third-party management arranged by our technical managers. All vessel owning-companies are subsidiaries of Tsakos Energy Navigation Limited. Approximately 3,000 officers and crew members served on board the vessels we own and were managed by our technical managers as of December 31, 2024.

Share Ownership

The Common Shares beneficially owned by our directors and executive officers and/or companies affiliated with these individuals are disclosed in “Security Ownership of Certain Beneficial Owners and Management” above.

Stock Compensation Plan

On May 1, 2024, our Board of Directors adopted, in accordance with Bermuda law, the Tsakos Energy Navigation Limited 2024 Equity Incentive Plan (the “2024 Plan”), which replaced the share-based incentive plan

(the “2012 Plan”) adopted in 2012. The 2024 Plan permits us to grant share options or other share based awards with respect to up to 1,000,000 of our common shares to our directors and officers, to the officers of the vessels in the fleet, and to the directors, officers and employees of our manager, Tsakos Energy Management, and our commercial and technical manager, Tsakos Shipping.

The purpose of the 2024 Plan is to provide a means to attract, retain, motivate and reward the persons whose performance of administrative, commercial, management, technical and maritime services are important for the Company by increasing their ownership in our Company. Awards under the 2024 Plan may include options to purchase our common shares, restricted stock units, restricted share awards, other share-based awards (including share appreciation rights granted separately or in tandem with other awards) or a combination thereof.

The 2024 Plan is administered by our Corporate Governance, Nominating and Compensation Committee. Such committee has the authority, among other things, to: (i) select the present or prospective directors, officers, consultants and other personnel entitled to receive awards under the 2024 Plan; (ii) determine the form of awards, or combinations of awards; (iii) determine the number of shares covered by an award; and (iv) determine the terms and conditions of any awards granted under the 2024 Plan, including any restrictions or limitations on transfer, any vesting schedules or the acceleration of vesting schedules and any forfeiture provision or waiver of the same.

In 2023 and 2022, no awards were issued under our 2012 Plan. In 2024, we granted an aggregate of 625,000 restricted common shares under the 2024 Plan to Company directors, officers and other employees and persons who provide services to the Company and its subsidiaries and employees of any management company. The restricted shares are scheduled to vest upon satisfaction of the time-based and performance-based conditions. The time-based condition will be satisfied so long as the participant continues to have a service relationship with the Company or its subsidiaries or any management company on the applicable vesting dates. The performance-based condition will be satisfied upon determination by the Company that the fleet utilization as defined in the awards, equals or exceeds 85% for the period from January 1, 2024 through the end of the last complete fiscal quarter preceding each vesting date. The vesting schedule is as follows: 25% of the shares granted to each recipient on January 1, 2025, 25% to vest on July 1, 2025, 25% to vest on January 1, 2026, and 25% to vest on July 1, 2026. Total stock-based compensation expense recognized for 2024 relating to these restricted shares amounted to $8.1 million, of which $1.7 million was for restricted shares granted to executive officers and $1.1 million was for restricted shares granted to non-executive directors. No stock-based compensation expense was recognized in the years ended December 31, 2023 and 2022.

Total stock compensation expense recognized was $nil for the years ended December 31, 2023 and December 31, 2022.

REPORT OF THE AUDIT COMMITTEE

The Tsakos Energy Navigation Limited Audit Committee of the Board is composed entirely of non-management directors. The members of the Audit Committee meet the independence and financial literacy requirements set forth by the SEC and the NYSE and Nicholas F. Tommasino, Efstratios Georgios Arapoglou and Denis Petropoulos each qualify as an “audit committee financial expert” as defined by the SEC.

The Audit Committee of the Board operates pursuant to a written charter, which may be accessed through the Corporate Governance section of the Company’s website at http://www.tenn.gr. In accordance with this charter, the Audit Committee assists the Board of Directors in fulfilling its oversight responsibility relating to the integrity of the Company’s financial statements and system of internal controls. The Audit Committee reviews and assesses the adequacy of its charter on an annual basis.

The Company’s Management team has the primary responsibility for the financial statements and the reporting process, including the system of internal controls. The Audit Committee assists the Board in its general oversight of the Company’s financial reporting processes. Specifically, the Audit Committee:

•

Reviewed and discussed the Company’s annual audited financial statements and quarterly financial statements, including the Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the Company’s Form 20-F for the year ended December 31, 2024, with Company management and Ernst & Young (Hellas), its Independent Auditors.

•

The Committee also reviewed related issues and disclosure items, including the Company’s earnings press releases, and performed its regular review of critical accounting policies and the processes by which the Company’s Chief Executive Officer and Co-Chief Financial Officers certify the information contained in its quarterly and annual filings.

•

Discussed with Ernst & Young (Hellas) the matters required to be discussed by the Public Company Accounting Oversight Board. The Committee also received the written disclosures and letter from Ernst & Young (Hellas) required by applicable requirements of the Public Company Accounting Oversight Board regarding Ernst & Young (Hellas)’s communications with the Audit Committee concerning independence and discussed with Ernst & Young (Hellas) their independence and related matters.

•

As part of its review of audit matters, the Audit Committee supervises the relationship between the Company and its independent public accountants, including: having responsibility to recommend to the Board for Shareholder approval the selection, compensation and retention of the independent public accountants; approving the nature and type of their services; approving their audit and non-audit services; reviewing the plan for and the results of the annual audit and quarterly reviews of the Company’s Consolidated Financial Statements; and confirming their independence. The Audit Committee has evaluated Ernst & Young (Hellas)’s qualifications, performance and independence, including that of the lead audit partner. As part of the engagement process, the Audit Committee considers whether to rotate the independent public accountants. The Audit Committee has recommended to the Board that the Shareholders approve the selection of Ernst & Young (Hellas) as the Company’s independent public accountants for the year 2025.

During the year 2024, the Audit Committee held three meetings. During these meetings, the Audit Committee met with representatives of Ernst & Young (Hellas), both with management present and in private sessions without management present, to discuss the results of the audit and to solicit their evaluation of the Company’s accounting principles, practices and judgments applied by management and the quality and adequacy of the Company’s internal controls. At such meetings, the Audit Committee also met in private sessions with the Head of Compliance & Internal Audit, who reports directly to the Audit Committee, to discuss the audit results for 2024 and audit plans for 2025. The Audit Committee continually reviews specific areas of risk management with the Company.

In performing the above described functions, the Audit Committee acts only in an oversight capacity and necessarily relies on the work and assurances of Company management and the independent public accounting firm, which, in their report, expresses an opinion on the conformity of the Company’s annual financial statements to accounting principles generally accepted in the United States.

In addition, in reliance upon the reviews and discussions as outlined above, the Audit Committee recommended, and the Board of Directors approved, the inclusion of the Company’s audited financial statements in its annual report on Form 20-F for the year ended December 31, 2024 for filing with the SEC and presentation to the Company’s shareholders.
