SEC Form DEF 14A filed by Sky Harbour Group Corporation

The Annual Meeting will be held at our corporate offices located at Conference Room 2, Terminal M, 136 Tower Road, Westchester County Airport, White Plains, New York 10604.

We have elected to take advantage of rules adopted by the Securities and Exchange Commission that allow companies to furnish proxy materials to their stockholders by providing notice of and access to these documents on the Internet instead of mailing printed copies. Those rules allow a company to provide its stockholders with the information they need, while lowering the costs of delivery and reducing the environmental impact of the Annual Meeting. Most of our stockholders will not receive printed copies of our proxy materials unless requested, but instead will receive a Notice of Internet Availability of Proxy Materials, or Notice, with instructions on how they may access and review our proxy materials and our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 on the Internet and how they may cast their vote via the Internet. If you would like to receive a printed or e-mail copy of our proxy materials, please follow the instructions for requesting the materials in the Notice that is being sent to you.

Details regarding admission to the Annual Meeting and the business to be conducted are described in the accompanying proxy materials. We encourage you to read this information carefully.

Your vote is important. Whether or not you plan to attend the Annual Meeting, we hope you will vote as soon as possible. You may vote over the Internet, by telephone or by mailing a proxy card. Voting over the Internet, by telephone or by written proxy will ensure your representation at the Annual Meeting regardless of whether or not you attend in person. We urge you to read the accompanying material regarding the matters to be voted on at the meeting and to submit your voting instructions using one of these voting options.

Thank you for your ongoing support of Sky Harbour Group Corporation.

Your vote is important. Whether or not you plan to attend the Annual Meeting, we hope you will vote as soon as possible. You may vote over the Internet, by telephone or by mailing a proxy card. Voting over the Internet, by telephone or by written proxy will ensure your representation at the Annual Meeting regardless of whether or not you attend in person.

Beginning on or about May 5, 2025, a Notice of Internet Availability of Proxy Materials (the “Notice of Internet Availability”) will be mailed to our stockholders of record as of the Record Date. In addition, the proxy statement, the accompanying proxy card or voting instruction form, and our 2024 Annual Report to Stockholders (the “2024 Annual Report”) are available at www.proxyvote.com. As more fully described in the Notice of Internet Availability, all stockholders may choose to access these materials online or may request printed or emailed copies.

If you have any questions regarding this information or the proxy materials, please visit the investor relations page of our website at www.skyharbour.group or contact our investor relations department at [email protected].

We have prepared these materials for our 2025 annual meeting of stockholders (the “Annual Meeting”). The Annual Meeting is scheduled to be held on Thursday, June 19, 2025 at 10:00 a.m. Eastern Time, and will be held at our corporate offices located at Conference Room 2, Terminal M, 136 Tower Road, Westchester County Airport, White Plains, New York 10604. You are invited to attend and are requested to vote on the proposals described in this Proxy Statement.

Pursuant to rules adopted by the U.S. Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials to our stockholders via the Internet. Accordingly, on or about May 5, 2025, we sent you a Notice of Internet Availability of Proxy Materials (the “Notice of Internet Availability”).

Pursuant to rules adopted by the SEC, the proxy materials, including the Notice of 2025 Annual Meeting of Stockholders (the “Notice of Annual Meeting”), this Proxy Statement and proxy card or, for shares held in street name (held for your account by a broker or other nominee), voting instruction form, and our 2024 Annual Report (collectively, the “Proxy Materials”), are available to stockholders on the Internet. We believe electronic delivery will expedite the receipt of materials and will help lower our costs and reduce the environmental impact of our annual meeting materials. Accordingly, we have sent a Notice of Internet Availability to stockholders of record and beneficial owners of our Class A common stock, par value $0.0001 per share (the “Class A Common Stock”) and Class B common stock, par value $0.0001 per share (the “Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”) as of April 22, 2025, the record date for the Annual Meeting (the “Record Date”). We have also provided a Notice of Internet Availability to holders of our warrants to purchase shares of our Class A common stock as of the Record Date.

The Notice of Internet Availability provides instructions as to how stockholders may access and review the Proxy Materials on the website referred to in the Notice of Internet Availability or, alternatively, how to request that a printed set of the Proxy Materials, including a proxy card, be sent to them by mail. The Notice of Internet Availability also provides voting instructions. In addition, stockholders of record may request to receive the Proxy Materials in printed form by mail or electronically by e-mail on an ongoing basis for future stockholder meetings. Please note that while our Proxy Materials are available at the website referenced in the Notice of Internet Availability, and our Notice of Annual Meeting, Proxy Statement and 2024 Annual Report are available on our website, no other information contained on either website is incorporated by reference in or considered to be a part of this Proxy Statement. Warrant holders will have access to the Proxy Statement and 2024 Annual Report but will not be entitled to vote.

There are two matters scheduled for a vote:

The Board recommends that you vote:

Only stockholders of record at the close of business on the Record Date, April 22, 2025, will be entitled to vote at the Annual Meeting. On the Record Date, there were 33,814,358 shares of the Company’s Class A Common Stock and 42,046,356 shares of the Company’s Class B Common Stock outstanding. The holders of our Class A Common Stock have the right to one vote for each share of Class A Common Stock they held as of the Record Date and the holders of our Class B Common Stock have the right to one vote for each share of Class B Common Stock they held as of the Record Date. The holders of our Class A Common Stock and Class B Common Stock are voting as a single class on all matters presented at the Annual Meeting.

Stockholders of Record. If shares of our Common Stock are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered the stockholder of record with respect to those shares of Common Stock, and the Proxy Materials were provided to you directly by us. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or to vote live at the Annual Meeting. Throughout this Proxy Statement, we refer to these registered stockholders as “stockholders of record.”

Street Name Stockholders. If shares of our Common Stock are held on your behalf in a brokerage account or by a bank or other nominee, you are considered to be the beneficial owner of shares of Common Stock that are held in “street name,” and the Proxy Materials were forwarded to you by your broker, bank or other nominee, who is considered the stockholder of record with respect to those shares of Common Stock. As the beneficial owner, you have the right to direct your broker, bank or other nominee as to how to vote your shares. Beneficial owners are also invited to attend the Annual Meeting.

Warrant holders will have access to the Proxy Statement and 2024 Annual Report but will not be entitled to vote.

Stockholders of record may vote over the Internet, by telephone or by mail as described below. Stockholders also may attend the Annual Meeting and vote in person. The method you use to vote will not limit your right to vote at the Annual Meeting if you decide to attend the Annual Meeting in person. Whether or not you plan to attend the Annual Meeting in person, we encourage you to vote your shares before the Annual Meeting over the Internet, by phone or by mail.

As a street name stockholder, you have the right to direct your broker, bank or other nominee regarding how to vote the shares in your account by following the instructions provided by your broker, bank or other nominee. You are also invited to attend the Annual Meeting. The Proxy Materials you receive from your broker, bank or other nominee will include your unique control number.

If you return a signed and dated proxy card without marking any voting selections, your shares will be voted in accordance with the recommendations of our Board stated above, namely: (i) “FOR” the election of all seven of our director nominees to serve until the 2026 Annual Meeting; and (ii) “FOR” the ratification of the appointment of EA as our independent registered public accounting firm for the fiscal year ending December 31, 2025. However, if you are a street name stockholder, you must provide voting instructions to your broker, bank or other nominee in accordance with their instructions in order for your shares to be properly voted. If any other matter is properly presented at the meeting, your proxy (one of the individuals named on your proxy card) will vote your shares using their best judgment.

As of the date of this Proxy Statement, we do not know of any matters to be raised at the Annual Meeting other than those referred to in this Proxy Statement. If other matters are properly presented at the Annual Meeting for consideration and you are a stockholder of record and have submitted a proxy card, the persons named in your proxy card will have the discretion to vote on those matters for you.

If you receive more than one set of Proxy Materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the proxy cards in the Proxy Materials to ensure that all of your shares are voted.

Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. A stockholder of record may revoke a proxy in any one of three ways:

If you are a street name stockholder, you must contact your bank, broker or other nominee in order to find out how to change your vote.

Proxies may be solicited on behalf of our Board by our directors and employees. In addition to these mailed Proxy Materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies.

We will pay for the entire cost of soliciting proxies. We may reimburse brokerage firms, banks and other agents for the cost of forwarding Proxy Materials to street name stockholders.

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if the holders of a majority in voting power of shares of Class A Common Stock and Class B Common Stock outstanding as of the Record Date are present or represented by proxy. Abstentions and broker non-votes will be counted towards the quorum requirement.

A broker non-vote occurs when shares held through a broker are not voted with respect to a proposal because (1) the broker has not received voting instructions from the stockholder who beneficially owns the shares and (2) the broker lacks the authority to vote the shares at its discretion on a non-routine proposal. The rules of the New York Stock Exchange (“NYSE”) determine whether matters presented at the Annual Meeting are “routine” or “non-routine” in nature. Proposal 1 regarding the election of directors is considered a non-routine matter, and a broker will lack the authority to vote uninstructed shares at their discretion on such proposals. Proposal 2 is considered a routine matter, and as a result brokers will be permitted to exercise their discretionary authority to vote for the ratification of the appointment of auditors. We encourage you to provide voting instructions to your broker, whether or not you plan to attend the Annual Meeting.

We will count a properly executed proxy card marked “Abstain” as present for purposes of determining whether a quorum is present, but the shares represented by that proxy card will not be voted at the Annual Meeting for the proposals so marked.

Preliminary voting results will be announced at the Annual Meeting. Final voting results will be available in a Current Report on Form 8-K filed with the SEC within four business days after the end of the Annual Meeting.

We believe Mr. Moelis is qualified to serve on our Board because of his significant investment experience.

We have structured our corporate governance in a manner we believe closely aligns our interests with those of our stockholders. Notable features of our corporate governance structure include the following:

Our directors will stay informed about our business by attending meetings of the Board and its committees and through supplemental reports and communications. Our independent directors will meet regularly in executive sessions without the presence of our corporate officers or non-independent directors.

Under the rules of the NYSE, a director will only qualify as an “independent director” if such person is not an officer or employee of the company or its subsidiaries and such person does not have a relationship, which, in the opinion of the Board, would interfere with the director’s exercise of independent judgment in carrying out the responsibilities of a director. Our Board, following consultation with our Nominating and Governance Committee, undertook a review of the independence of each director and director nominee and considered whether each director and director nominee has a material relationship with the Company and Sky that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, the Board determined that five of our seven current directors, Messrs, Jackson, Rozek, Wellmon and Moelis and Mmes. Nancoo and Leiponis are considered “independent” as defined under the listing requirements and rules of the NYSE, and that Messrs. Jackson and Moelis and Mmes. Nancoo and Leiponis are considered independent for purposes of audit committee service under Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In making these determinations, the Board considered the current and prior relationships that each non-employee director and director nominee has with the Company and Sky and all other facts and circumstances the Board deemed relevant in determining independence, including the beneficial ownership of the Company’s Common Stock held by each non-employee director and director nominee and the transactions involving them described in the section entitled “Certain Relationships and Related Party Transactions.”

Our Corporate Governance Guidelines provide our Board with the flexibility to combine the position of Chief Executive Officer with the position of Chairman of the Board in accordance with its determination that utilizing one or the other structure would be in our best interests. Currently, Mr. Keinan serves as Chief Executive Officer and Chairman of the Board. Our Board has determined that combining the roles of Chief Executive Officer and Chairman of the Board is in the best interests of our Company and its stockholders at this time because it promotes unified leadership by Mr. Keinan and allows for a single, clear focus for management to execute the Company’s strategy and business plans.

Our Corporate Governance Guidelines provide that, if the Chairperson of the Board is not an independent director, the Board will annually designate a Lead Independent Director. Though annually designated, the Lead Independent Director is generally expected to serve in such capacity for more than one year. The Lead Independent Director’s responsibilities include presiding at executive sessions of the independent directors, serving as the focal point of communication to the Board regarding management plans and initiatives, ensuring that the role between Board oversight and management operations is respected, providing the medium for informal dialogue with and between independent directors, allowing for free and open communication within that group and performing other functions as requested by the Board from time to time. The Lead Independent Director may be redesignated at any time by a majority of the independent members of the Board.

Our Chairman of the Board is Tal Keinan. Under the NYSE rules, Mr. Keinan is not an independent director. Thus, the Board has also appointed Lysa Leiponis as our Lead Independent Director. Our Board has concluded that our current leadership structure is appropriate at this time. However, our Board will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

One of the key functions of the Board is informed oversight of our risk management process. The Board administers this oversight function directly, with support from its three standing committees, the Audit Committee, the Nominating and Corporate Governance Committee and the Compensation Committee, each of which addresses risks specific to their respective areas of oversight. In particular, our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance guidelines and code of business conduct and ethics, including whether they are successful in preventing illegal or improper liability-creating conduct. Our Compensation Committee will assess and monitor whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

We have adopted an anti-hedging policy, which is designed to prevent any of our directors, officers or employees from entering into a transaction in our securities that is designed to hedge the risks of ownership of our securities. The policy specifically prohibits the purchase or sale of puts, calls, options or other derivative securities based on our securities, as well as prohibits hedging or monetization transactions, such as forward sale contracts, by our directors, officers or employees.

Our Board has adopted an insider trading policy, which governs the purchase, sale and/or other dispositions of our shares by our directors and officers that is reasonably designed to promote compliance with insider trading laws, rules and regulations and applicable NYSE standards.

Stockholders and any interested parties may communicate directly with the independent directors either by writing to the Board, a Board committee, or an individual director at the Company’s principal executive offices or by emailing [email protected]. Management receives all letters and emails sent and forwards proper communications to the Board, a Board committee, or an individual director, who facilitates an appropriate response. Management generally will not forward communications that are primarily solicitations for products or services, matters of a personal nature that are not relevant for stockholders, matters that are of a type that render them improper or irrelevant to the functioning of the Board, or requests for general information about the Company.

The Board has developed and adopted a set of corporate governance principles to provide the framework within which the Board may conduct its oversight of the business and affairs of the Company. These guidelines reflect the Board’s commitment to monitoring the effectiveness of policy and decision making both at the Board and management level, with a view to enhancing stockholder value over the long term. The Corporate Governance Guidelines set forth the practices the Board intends to follow with respect to, among other topics, the role of the Board and management, principal responsibilities and duties of the Board, Board structure and composition, Board procedures, Board committees and Board communication with Company stakeholders. A copy of our Corporate Governance Guidelines can be found on the investor relations page of our website at https://ir.skyharbour.group.

Our Board formed and constituted our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee in January 2022. Our Board may establish other committees to facilitate the management of our business. Our Board and its committees will set schedules for meetings throughout the year and can also act by written consent from time to time, as appropriate. Our Board delegated various responsibilities and authority to its committees as generally described below. The committees regularly report on their activities and actions to the full Board. Each committee of our Board has a written charter approved by our Board. Members will serve on these committees until their resignation or until otherwise determined by our Board. The following table provides membership information for each of such Board committee as of the date of this Proxy Statement:

Our Board had eight meetings and executed two actions by unanimous written consent in the year ended December 31, 2024. All directors attended all meetings.

The standing committees of the Board consist of an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. The composition of each committee and the responsibilities of each of the committees is described below. Members will serve on these committees until their resignation or until as otherwise determined by the Board.

The Audit Committee is composed of Ms. Leiponis and Messrs. Jackson and Moelis, with Mr. Jackson serving as chair of the committee. The Board determined that each of the foregoing meet the independence requirements of Rule 10A-3 under the Exchange Act and the applicable listing standards of the NYSE. The Board determined that Mr. Jackson is an “audit committee financial expert” within the meaning of SEC regulations and applicable listing standards of the NYSE. The Audit Committee’s responsibilities include:

Our Audit Committee had six meetings and executed no actions by written consent in the year ended December 31, 2024. All Audit Committee members attended all meetings of the Audit Committee.

The Compensation Committee is composed of Messrs. Keinan, Jackson, Rozek and Wellmon and Mses. Leiponis and Nancoo, with Ms. Nancoo serving as chair of the committee. Under NYSE listing standards, as a controlled company, the Company is not required to have a compensation committee composed entirely of independent directors. While the Company may rely upon this exemption for controlled companies in the future, the Board determined that each of Mses. Leiponis and Nancoo and Messrs. Jackson, Rozek and Wellmon is independent under the applicable listing standards of the NYSE. The Compensation Committee’s responsibilities include:

The Compensation Committee may form and delegate its authority to subcommittees when appropriate.

As part of the executive compensation process, our Compensation Committee reviewed the extent to which the Company and individual executives, including the Chief Executive Officer, had achieved the performance objectives

that had been established by the Compensation Committee in 2023 as well as the recommendations made by the Chief Executive Officer to the Compensation Committee regarding the form and amount of compensation to be paid to each executive officer, other than himself, as well as other factors such as the economic environment including the impact of inflation on our operating results, the form and amount of compensation to be paid and other relevant factors.

Final deliberations and decisions regarding executive compensation were made by the Compensation Committee, and, in the case of compensation to be paid to our Chief Executive Officer, without the presence of any of our executive officers.

Our Compensation Committee had one meeting and executed one action by unanimous written consent in the year ended December 31, 2024. All Compensation Committee members attended all meetings of the Compensation Committee.

The Company’s Nominating and Corporate Governance Committee is composed of Messrs. Keinan, Moelis and Rozek and Mses. Leiponis and Nancoo, with Ms. Leiponis serving as chair of the committee. Under NYSE listing standards, as a controlled company, the Company is not required to have a nominating and corporate governance committee comprised entirely of independent directors. While the Company may rely upon this exemption for controlled companies in the future, the Board determined that Mses. Leiponis and Nancoo and Messrs. Moelis and Rozek are independent under the applicable listing standards of the NYSE. The Nominating and Corporate Governance Committee’s responsibilities include:

Our Nominating and Corporate Governance Committee had one meeting and executed no actions by unanimous written consent in the year ended December 31, 2024. All Nominating and Corporate Governance Committee members attended all meetings of the Nominating and Corporate Governance Committee.

Our Audit Committee, Compensation Committee, and Nominating and Governance Committee operate under written charters adopted by the Board. These charters are posted on the “Investor Relations” page of our website, https://ir.skyharbour.group/. The information on our website is not incorporated by reference into this Proxy Statement

There are no family relationships among any of our directors or executive officers.

Our bylaws limit the liability of our directors and officers to the fullest extent permitted by the DGCL and we provide them with customary indemnification and advancement and prepayment of expenses. We have entered into customary indemnification agreements with each of our executive officers and directors that provide them, in general, with customary indemnification in connection with their service to us or on our behalf.

We qualify as a “controlled company” within the meaning of the corporate governance standards of the NYSE. Under these rules, a listed company of which more than 50% of the voting power is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain corporate governance requirements, including the requirements that (i) a majority of our Board consist of independent directors, (ii) our Compensation Committee be composed entirely of independent directors and (iii) our Nominating and Corporate Governance Committee be composed entirely of independent directors.

We are not currently relying on any of these exemptions. However, we may in the future rely on some or all of these exemptions. To the extent we rely on any of these exemptions, holders of Class A Common Stock will not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the NYSE.

We have adopted a code of conduct and ethics that applies to our directors, officers and employees in accordance with applicable federal securities laws, a copy of which is available on the investor relations page of our website at www.skyharbour.group. The Company will make a printed copy of the code of conduct and ethics available without charge to any stockholder who requests. Requests for a printed copy may be directed to: [email protected].

If the Company amends or grants a waiver of one or more of the provisions of the Company’s code of ethics, it intends to satisfy the requirements under Item 5.05 of Item 8-K regarding the disclosure of amendments to or waivers from provisions of our code of ethics that apply to our principal executive officer, principal financial officer and principal accounting officer by posting the required information on the “Investor Relations” page on our website at https://ir.skyharbour.group/. The information on our website is not incorporated by reference into this Proxy Statement.

The Nominating and Corporate Governance Committee has the responsibility for reviewing and recommending to the Board candidates for director positions. The Nominating and Corporate Governance Committee will consider nominations made by stockholders. There are no differences in the manner in which the Nominating and Corporate Governance Committee evaluates nominees for director based on whether the nominee is recommended by a stockholder or whether the recommendation comes from another source. To have a candidate considered by the Nominating and Corporate Governance Committee, a stockholder must submit such stockholder’s recommendation in writing in accordance with the procedures described in the section of this Proxy Statement entitled “Stockholder Nominations and Proposals for the 2026 Annual Meeting of Stockholders” and must include the information specified in our bylaws, including information concerning the nominee and information about the stockholder’s ownership of, and agreements related to, our stock.

The Nominating and Corporate Governance Committee, in evaluating Board candidates, considers factors such as character, integrity, judgment, diversity, age, independence, skills, education, expertise, business acumen, business experience, length of service, understanding of our business, and other commitments and the like, all in the context of an assessment of the needs of the Board at the time. The Nominating and Corporate Governance Committee’s objective is to maintain a Board of individuals of the highest personal character, integrity, and ethical standards, that reflect a range of professional backgrounds and skills relevant to our business. The Nominating and Corporate Governance Committee does not have a formal policy with respect to diversity.

The Nominating and Corporate Governance Committee believes that the minimum qualifications for serving as a director are that a nominee demonstrate knowledge of our industry, accomplishment in his or her field, an ability to make a meaningful contribution to the Board’s oversight of our business and affairs, independence under NYSE rules, lack of conflicts of interest, and a record and reputation for integrity and ethical conduct in both his or her professional and personal activities. In addition, the Nominating and Corporate Governance Committee examines a candidate’s specific experiences and skills, time availability in light of other commitments, interpersonal skills and compatibility with the Board, and ability to complement the competency and skills of the other Board members.

The Nominating and Corporate Governance Committee annually reviews with the Board the requisite skills and characteristics of Board members, as well as the composition of the Board as a whole. This assessment includes a consideration of independence, diversity, age, skills, and experience and industry backgrounds in the context of the needs of the Board and the Company, as well as the ability of current and prospective directors to devote sufficient time to performing their duties in an effective manner. Directors are expected to exemplify the highest standards of personal and professional integrity, and to constructively challenge management through their active participation and questioning. In particular, the Nominating and Corporate Governance Committee seeks directors with established strong professional reputations and expertise in areas relevant to the strategy and operations of our business.

In performing its duties, the Nominating and Corporate Governance Committee may consult with internal or external legal counsel and expert advisers.

We, and certain of our stockholders who own in the aggregate 11,939,462 shares of Class A Common Stock, 41,222,212 shares of Class B Common Stock, and 7,719,779 warrants to purchase Class A Common Stock as of the Record Date (collectively, the “Stockholder Parties”), entered into a Stockholders’ Agreement, dated January 15, 2022 (the “Stockholders’ Agreement”), pursuant to which, among other things, the Stockholder Parties agreed to vote all of our securities that may be voted in the election of our directors held by such Stockholder Parties in accordance with the provisions of the Stockholders’ Agreement. Pursuant to the Stockholders’ Agreement, Tal Keinan and his permitted designees (collectively, the “Founder Holders”) have the right to designate four of our seven directors (each, a “Founder Designee” and collectively, the “Founder Designees”) at any time. Each of Due West and its permitted designees (the “Due West Holders”), Center Sky and its permitted designees (collectively, the “Center Sky Holders”) and the Sponsor and its permitted designees (collectively, the “Sponsor Holders”) have the right to designate one director (the “Due West Designee,” “Center Sky Designee” and the “Sponsor Designee,” as applicable).

In the event that the Founder Holders collectively cease, as of any date after January 25, 2022 (the “Closing Date”), to own our voting stock bearing greater than: (1) thirty-three percent (33%) of the outstanding voting power of the Company held by them at the closing of the Yellowstone Transaction (the “Closing”), the Founder Holders shall only be entitled to nominate three members of our Board as of the date Founder Holders cease to hold the aforementioned requisite securities of the Company; (2) twenty-five percent (25%) of the outstanding voting power of the Company held by them at the Closing, the Founder Holders shall only be entitled to nominate two members of the Company as of the date Founder Holders cease to hold the aforementioned requisite securities of the Company; (3) fifteen percent (15%) of the outstanding voting power of the Company held by them at the Closing, the Founder Holders shall only be entitled to nominate one member of the Board as of the date Founder Holders cease to hold the aforementioned requisite securities of the Company; and (4) five percent (5%) of the outstanding voting power of the Company held by them at the Closing, the Founder Holders shall no longer be entitled to nominate any members of the Board as of the date the Founder Holders cease to hold the aforementioned requisite securities of the Company. The Stockholder Parties agree that, in the event the size of the Board is increased or decreased, the number of Founder Designees that the Founder Holders are entitled to appoint to the Board shall increase or decrease proportionately to the size of the Board. Notwithstanding the foregoing, for so long as the Founder Holders are entitled to nominate at least four members of the Board, at least one Founder Designee must (x) qualify as an “independent director” under NYSE Rules and (y) qualify as an “audit committee financial expert” within the meaning of Regulation S-K of the Securities Act of 1933, as amended (the “Securities Act”). The Founder Holders’ rights to designate directors shall be terminated as set forth in the Stockholders’ Agreement.

Until the Due West Fall-Away Date (as defined below), the Due West Holders, by a majority of shares held by them, shall have the right to nominate, and the Board and the Stockholder Parties will appoint and vote for, the Due West Designee. The Due West Holders have nominated Nick Wellmon to serve as a director. The Due West Designee must at all times qualify as an “independent director” under NYSE Rules. The “Due West Fall-Away Date” shall be the first date following the Closing Date on which either of the following events occurs: (A) the Due West Holders cease to own voting stock of the Company bearing greater than thirty-three percent (33%) of the outstanding voting power of the Company held by them at the Closing; or (B) Due West’s designation rights have been terminated as set forth in the Stockholders’ Agreement.

Until the Center Sky Fall-Away Date (as defined below), the Center Sky Holders, by a majority of shares held by them, shall have the right to nominate, and the Board and the Stockholder Parties will appoint and vote for, the Center Sky Designee. The Center Sky Holders nominated Jordan Moelis as the Center Sky Designee beginning with the 2024 Annual Meeting and have again nominated Mr. Moelis as the Center Sky Designee for the Annual Meeting. Robert Rivkin was previously the Center Sky Designee. The Center Sky Designee must at all times qualify as an “independent director” under NYSE Rules. The “Center Sky Fall-Away Date” shall be the first date following the Closing Date on which either of the following events occurs: (A) the Center Sky Holders cease to own voting stock of the Company bearing greater than thirty-three percent (33%) of the outstanding voting power of the Company held by them at the Closing; or (B) Center Sky’s designation rights have been terminated as set forth in the Stockholders’ Agreement.

Until the Sponsor Fall-Away Date (as defined below), the Sponsor Holders, by a majority of shares held by them, shall have the right to nominate, and the Board and the Stockholder Parties will appoint and vote for, the Sponsor Designee. The Sponsor Holders have nominated Alex B. Rozek to serve as a director. The Sponsor Designee

must at all times qualify as an “independent director” under NYSE Rules. The “Sponsor Fall-Away Date” shall be the first date following the Closing Date on which either of the following events occurs: (A) the Sponsor Holders jointly cease to own voting stock of the Company bearing greater than thirty-three percent (33%) of the outstanding voting power of the Company held by them at the Closing; or (B) the Sponsor’s designation rights have been terminated as set forth in the Stockholders’ Agreement.

The right of any of the Stockholder Parties to designate nominees for appointment to the Board as set forth above shall terminate if at any time (A) such Stockholder Designating Party (as defined in the Stockholders’ Agreement) or any of its affiliates becomes a Competitor (as defined below) of the Company, (B) such Stockholder Designating Party or any of its affiliates commences any legal proceeding against the Company, its subsidiaries or any other member of the Board; or (C) such Stockholder Designating Party or any of its affiliates has the right (whether exercised or not) to designate or appoint a member of or observer to the board of directors (or similar governing body) of any competitor. For purposes of the Stockholders’ Agreement, a “Competitor” shall mean a person engaged, directly or indirectly (including through any partnership, limited liability company, corporation, joint venture or similar arrangement (whether now existing or formed hereafter)), in the business of developing and leasing airport real estate infrastructure in North America but shall not include any financial investment firm or collective investment vehicle that, together with its affiliates, holds less than ten percent (10%) of the outstanding equity of any Competitor and does not, nor do any of its affiliates, have a right to designate any members of the board of directors of any Competitor.

Pursuant to the Stockholders’ Agreement, each nominee to the Board must at all times, satisfy all requirements for service as a director under applicable law, NYSE rules, and any other qualifications as the Board may adopt. Additionally, any such members of, or nominees to, the Board cannot have been disqualified as a “Bad Actor” under Section 506 of Regulation D of the Securities Act, involved in any event enumerated under Item 2(d) or (e) of Schedule 14D under the Exchange Act or Item 401(f) (other than Item 401(f)(1)), of Regulation S-K of the Securities Act, or be subject to any governmental order prohibiting service as a director of a public company. Further, any such nominee or director must agree to be bound to a confidentiality agreement in a form acceptable to the Company and must recuse themselves from deliberations and discussions that, in the reasonable determination of the Board, present an actual or potential conflict of interest with the Company.

In addition to any vote or consent required by the Board or stockholders of the Company, the Company may not change the size of the Board, establish any committee of the Board, change the composition or powers of any committees of the Board (subject to certain exceptions), engage any professional advisers or materially change the nature or scope of the Company’s business or enter into or abandon a line of business, in each case without the consent of a majority of the shares held by the Stockholder Parties. This consent right terminates automatically on the first date on which the combined voting power of the Stockholder Parties no longer exceeds 50% of the total voting power of the Company then outstanding.

For so long as the Sponsor Holders continue to own voting stock of the Company bearing at least twenty percent (20%) of the outstanding voting power of the Company held by them at the Closing, the Sponsor shall be entitled to designate one individual to receive notice of and to attend Board meetings on a non-voting basis (a “Board Observer”). Board Observers will receive copies of any materials distributed to members of the Board in connection with any meeting or consent solicitation. The Board may exclude such Board Observer from any portion of the Board meeting or Board materials where, in the exercise of its reasonable discretion, it believes such exclusion is necessary to preserve attorney-client privilege.

Subject to certain exceptions, each Stockholder Party’s obligation to vote its shares of the Company in accordance with the Stockholders’ Agreement is terminated on the first date on which such Stockholder Party no longer has the right to designate a director to the Board. Certain other obligations of each Stockholder Party terminate automatically when such Stockholder Party ceases to own shares of the Company.

Currently, our officers are appointed by the Board and serve at the discretion of the Board, rather than for specific terms of office. Our Board is authorized to appoint persons to the offices set forth in our bylaws as it deems appropriate. Our bylaws provide that our officers may consist of a Chairman of the Board, Chief Executive Officer, Chief Financial Officer, President, Vice Presidents, Secretary, Treasurer, Assistant Secretaries and such other offices as may be determined by the Board.

The following table sets forth information known to us regarding the beneficial ownership of the Class A Common Stock and Class B Common Stock as of April 18, 2025 by:

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days and shares issuable upon the settlement of restricted stock unit (“RSU”) awards held by that person that will vest within 60 days.

The beneficial ownership percentages set forth in the table below are based on approximately 33,858,394 shares of Class A Common Stock and approximately 42,046,356 shares of Class B Common Stock issued and outstanding as of April 18, 2025 and do not take into account the issuance of any shares of Class A Common Stock upon the exercise of warrants to purchase up to approximately 15,798,155 shares of Class A Common Stock that remain outstanding.

Unless otherwise noted in the footnotes to the following table, and subject to applicable community property laws, the persons and entities named in the table have sole voting and investment power with respect to their beneficially owned Class A Common Stock and Class B Common Stock.

Because of their ownership block, our directors and executive officers as a group may be able to effectively influence the outcome of all matters requiring approval by our stockholders, including amendments to our Amended and Restated Certificate of Incorporation and approval of significant corporate transactions.

We describe below the transactions and series of similar transactions, since January 1, 2023, to which we were a party or will be a party, in which:

In connection with the completion of the Yellowstone Transaction, we, and certain of our stockholders, entered into a Stockholders’ Agreement, dated January 15, 2022 (see “Directors, Executive Officers and Corporate Governance – Stockholders’ Agreement”).

Due West, Center Sky, Walter Jackson, Joshua Lobel, Haydeh Davoudi, Amodae Capital LLC, BOC YAC Funding LLC and Tal Keinan (the “Sky Securityholders”) entered into a Registration Rights Agreement, dated September 14, 2021, as amended (the “Registration Rights Agreement”), pursuant to which we granted the Sky Securityholders certain registration rights with respect to our securities owned by the Sky Securityholders. Among other things, the Registration Rights Agreement required us to register the shares of (a) Class A Common Stock issued in connection with the Yellowstone Transaction, (b) shares of Class A Common Stock issuable upon exchange of Sky Common Units and shares of the Class B Common Stock held by Sky Securityholders, and (c) the warrants sold by YAC to the Sponsor in its initial public offering (the “Private Placement Warrants”), including any shares of Class A Common Stock issuable upon the exercise of any Private Placement Warrants (collectively, the “Registerable Securities”). The Registration Rights Agreement also provides the Sky Securityholders with certain customary demand and piggyback registration rights.

Pursuant to the Registration Rights Agreement, we filed registration statements on Form S-1, originally filed with the SEC on April 28, 2022 and May 17, 2022 (File Numbers 333-263905 and 333-264998, respectively) (collectively, the “Registration Statements”), registering the resale of the Registrable Securities permitted to be registered for resale from time to time pursuant to the applicable rules and regulations under the Securities Act. The Registration Statements were declared effective on May 5, 2022, and May 25, 2022, respectively. We bore all of the expenses incurred in connection with the filing of the Registration Statements. We shall use reasonable best efforts to cause the Registration Statements to remain effective (including by renewing or refiling upon expiration), permitting the resale from time to time on a delayed or continuous basis pursuant to Rule 415 by the Sky Securityholders.

In connection with the completion of the Yellowstone Transaction, we, Sky, Tal Keinan (the “TRA Holder Representative”) and the TRA Holders (as defined therein), entered into a tax receivable agreement, dated as of January 25, 2022 (the “Tax Receivable Agreement”). Pursuant to the Tax Receivable Agreement, the Company is generally required to pay the LLC Interests 85% of the amount of savings, if any, in U.S. federal, state, local, and foreign taxes that are based on, or measured with respect to, net income or profits, and any interest related thereto that the Company realizes, or is deemed to realize, as a result of certain tax attributes, including:

On September 20, 2021, the Company entered into a non-exclusive agreement with Echo Echo, LLC, a related party to the Founder and CEO, Mr. Keinan, for the use of a Beechcraft Baron G58 aircraft. The effective date of the agreement was September 8, 2021 and the agreement automatically renews annually. The agreement can be terminated without penalty if either party provides 35 days' written notice, or if the aircraft is sold or otherwise disposed of. The Company is charged per flight hour of use along with all direct operating costs. Additionally, the Company will also incur the pro rata share of maintenance, overhead and insurance costs of the aircraft.

On September 19, 2024, the Company entered into an additional non-exclusive agreement with Echo Echo, LLC for the use of an Epic E1000GX aircraft. The effective date of the agreement was August 30, 2024 and the agreement automatically renews annually. The agreement can be terminated without penalty if either party provides 30 days' written notice, or if the aircraft is sold or otherwise disposed of. Additionally, the Company is responsible for reimbursing its pro rata share of the direct operating costs of the aircraft, exclusive of maintenance and insurance.

For the years ended December 31, 2024, and December 31, 2023, the Company recognized $372 and $215 of expense, within pursuit and marketing expense under the terms of this agreement. The related liability is included in accounts payable, accrued expenses and other liabilities on the consolidated balance sheet as of December 31, 2024.

In September, we entered into a Securities Purchase Agreement (the “2024 Purchase Agreement”) with certain investors, including a partnership controlled by one of our directors, Mr. Rozek, as well as his wife. In connection with the 2024 Purchase Agreement, Mr. Rozek indirectly acquired an aggregate of 128,875 shares of Class A Common Stock for $ $1,224,312.50. Mr. Rozek’s wife also acquired, pursuant to the 2024 Purchase Agreement, an aggregate of 128,875 shares of Class A Common Stock for $ $1,224,312.50. Mr. Rozek disclaims beneficial ownership of the shares acquired by his wife.

We have adopted a written policy relating to the approval of related person transactions. A “related person transaction” is a transaction or arrangement or series of transactions or arrangements in which we participate (whether or not we are a party) and a related person has a direct or indirect material interest in such transaction. Our Audit Committee will review and approve or ratify all relationships and related person transactions between us and (i) our directors, director nominees or executive officers, (ii) any record or beneficial owner of 5% or more of our common stock or (iii) any immediate family member of any person specified in (i) and (ii). The Audit Committee will review all related person transactions and, where the Audit Committee determines that such transactions are in our best interests, approve such transactions in advance of such transaction being given effect.

As set forth in the related person transaction policy, in the course of its review and approval or ratification of a related party transaction, the Audit Committee will, in its judgment, consider in light of the relevant facts and circumstances whether the transaction is, or is not inconsistent with, our best interests, including consideration of various factors enumerated in the policy.

Any member of the Audit Committee who is a related person with respect to a transaction under review will not be permitted to participate in the discussions or approval or ratification of the transaction. Our policy also includes certain exceptions for transactions that need not be reported and provides the Audit Committee with the discretion to pre-approve certain transactions.

Our Audit Committee will review on a quarterly basis all payments that were made to our officers or directors, or our or their affiliates.

For the years ended December 31, 2024 and 2023, our named executive officers consisted of Tal Keinan, our Chief Executive Officer, Francisco X. Gonzalez, our Chief Financial Officer, and Will Whitesell, our Chief Operating Officer. The policies of the Company with respect to the compensation of its executive officers are administered by the Board in consultation with the Compensation Committee. We may also rely on data and analyses from third parties, such as compensation consultants, in connection with its compensation programs. We intend to design and implement programs to provide for compensation that is sufficient to attract, motivate and retain executives of the Company and potential other individuals and to establish an appropriate relationship between executive compensation and the creation of stockholder value.

The following table sets forth information concerning the compensation of the named executive officers for the years ended December 31, 2024 and 2023.

The annual base salary of each named executive officer, and such officer’s incentive bonus opportunity, are expected to be reviewed from time to time and adjusted when our Board or Compensation Committee determines an adjustment is appropriate. For 2024 and 2023, our compensation program consisted of base salary and incentive compensation delivered in the form of cash bonuses, RSUs and stock options.¹

Each of our named executive officers is an at-will employee. Except as set forth below, we have not entered into any employment agreements or offer letters with our named executive officers.

On March 24, 2022, we entered into an employment agreement with Tal Keinan, Chief Executive Officer of the Company, effective as of January 1, 2022, which superseded all previous compensatory arrangements with Mr. Keinan (the “Keinan Employment Agreement”).

Compensation Arrangements. The Keinan Employment Agreement has an initial term of one year, subject to automatic renewal unless either party provides 60 days’ written notice of non-renewal. The Keinan Employment

Agreement provides for an initial base salary of $500,000, subject to periodic review and increase (but not decrease) by the Compensation Committee, and the Compensation Committee must review such base salary at least 90 days prior to the expiration of the Keinan Employment Agreement’s initial term. The Keinan Employment Agreement provides Mr. Keinan with a discretionary target annual incentive bonus equal to 100% of his base salary (the “Annual Bonus”) subject to certain performance metrics. Mr. Keinan’s actual Annual Bonus paid may be more or less than the target bonus. The Annual Bonus may be periodically reviewed and increased (but not decreased) at the discretion of the Compensation Committee of the Board. The Keinan Employment Agreement further provides for (i) reasonable business expense reimbursements, (ii) reimbursement of Mr. Keinan’s reasonable tax preparation expenses and (iii) other standard employee benefits the Company makes available to similarly situated employees.

Equity Awards. Under the Keinan Employment Agreement, Mr. Keinan was entitled to a one-time, time-based grant of restricted stock units (the “RSUs”) under our 2022 Incentive Award Plan (the “2022 Plan”). The RSUs vest over four years with 25% of the RSU Grant vesting on the first anniversary of the grant date and the remaining 75% of the RSU Grant will vest in equal monthly installments thereafter. Additionally, the RSUs vest in full upon a Change in Control (as defined the 2022 Plan), provided Mr. Keinan executes a general release of claims and covenant not to sue. The RSUs are also subject to vesting in full upon retirement if Mr. Keinan’s age plus years of service on his retirement date are equal to or greater than 65 (the “Rule of 65”). The RSUs are subject to additional terms and conditions under the 2022 Plan.

Additionally, as discussed below, under the Keinan Employment Agreement, all stock options, restricted stock units and other equity-based incentive awards subject to time-based vesting criteria will vest in full (or become payable immediately, as the case may be) upon a termination of Mr. Keinan’s employment by us for any reason (i) other than “Cause;” (ii) other than death; (iii) other than “Disability”; or if Mr. Keinan resigns for “Good Reason” (as those terms are defined in the Keinan Employment Agreement).

Obligations Upon Certain Termination Events. Under the Keinan Employment Agreement, if we terminate Mr. Keinan’s employment for any reason (i) other than “Cause;” (ii) other than death; (iii) other than “Disability”; or if Mr. Keinan resigns for “Good Reason,” we will pay him, subject to the restrictions noted below, (i) a continuation of base salary for two years after the date of termination; (ii) an amount equal to the highest Annual Bonus paid to Mr. Keinan within the three years preceding termination, each of (i) and (ii) in accordance with our ordinary payroll practices, and (iii) full vesting of any then-unvested, time-based equity awards.

Obligations in Connection with Death or Disability. In the event of Mr. Keinan’s death or Disability (as defined in the Keinan Employment Agreement), we will pay Mr. Keinan, subject to the restrictions noted below, (i) a prorated portion of his Annual Bonus based upon the applicable year’s target Annual Bonus multiplied by the percentage of the calendar year completed before terminating and (ii) full vesting of any then-unvested, time-based equity awards.

General Release and Restrictive Covenants. In addition, the payment of all severance benefits to Mr. Keinan is subject to him delivering an executed and irrevocable confidential separation agreement and general release of claims and his compliance with the following restrictive covenants:

The Company entered into an employment agreement with Mr. Whitesell, dated as of January 3, 2024 (the “Whitesell Employment Agreement”), setting forth Mr. Whitesell’s compensation, certain other terms, and the commencement of his employment on January 3, 2024 (the “Commencement Date”).

Pursuant to the Whitesell Employment Agreement, Mr. Whitesell will be paid an initial annual base salary of $500,000. Mr. Whitesell will be eligible to receive (1) an annual cash bonus with a target equal to 100% of his annual base salary and (2) an annual bonus consisting of RSUs with a target equal to 200% of his annual base salary, in each case at the discretion of the Compensation Committee upon achievement of performance goals to be established by the Compensation Committee and the Company’s Chief Executive Officer.

The Whitesell Employment Agreement also provides for an initial one-time grant of restricted stock units (the “Initial RSU Grant”) under the Plan to Mr. Whitesell in connection with the commencement of his employment. The

Initial RSU Grant was granted in February 2024 and consisted of 94,210 RSUs (which was equal to $1.1 million divided by the trading average of the Company’s common stock on the NYSE for the ten trading days preceding the grant date). The Initial RSU Grant vests over four years, with 25% of the RSUs vesting on the first anniversary of the grant date and the remaining 75% of the RSUs vesting in equal monthly installments thereafter, subject to Mr. Whitesell’s continued employment with the Company.

Compensation Arrangements. The Whitesell Employment Agreement further provides for (i) reasonable business expense reimbursements; (ii) reimbursement of Mr. Whitesell’s reasonable tax preparation expenses and (iii) other standard employee benefits we make available to similarly situated employees.

Obligations Upon Certain Termination Events. Under the Whitesell Employment Agreement, if the Company terminates Mr. Whitesell’s employment without “Cause,” or Mr. Whitesell resigns for “Good Reason” (as those terms are defined in the Whitesell Employment Agreement), any RSUs previously granted to Mr. Whitesell will continue to vest pursuant to the terms of the respective grants.

General Release and Restrictive Covenants. The payment of all severance benefits to Mr. Whitesell is subject to each delivering an executed and irrevocable confidential separation agreement and general release of claims.

On December 22, 2021, Sky entered into an amended and restated employment agreement with Mr. Gonzalez (the “A&R Gonzalez Employment Agreement”). Mr. Gonzalez has entered into Sky’s standard employee covenants agreement containing customary restrictive covenants. On March 24, 2022, we entered into an amendment to the A&R Gonzalez Employment Agreement in connection with his appointment as Chief Financial Officer, which was further amended on May 17, 2022 (the “Second Gonzalez Amendment”, and together with the A&R Gonzalez Employee Agreement, the “Gonzalez Employment Agreement”.)

Compensation Arrangements. The Gonzalez Employment Agreement provides for annual base salary, which is subject to periodic review and increase (but not decrease) by the Compensation Committee. The Gonzalez Employment Agreement further provides for performance metrics with respect to Mr. Gonzalez’s annual bonus and provides for (i) reasonable business expense reimbursements; (ii) reimbursement of Mr. Gonzalez’s reasonable tax preparation expenses and (iii) other standard employee benefits we make available to similarly situated employees.

Obligations Upon Certain Termination Events. Under the Gonzalez Employment Agreement, if we terminate Mr. Gonzalez’s employment without “Cause,” or Mr. Gonzalez resigns for “Good Reason” (as those terms are defined in the Gonzalez Employment Agreement), we will pay Mr. Gonzalez, subject to the restrictions noted below, a continuation of base salary equal to 24 months, paid in equal installments in accordance with our ordinary payroll practices. If we waive the restrictions in (i) and (ii) below in full or in part, the number of months of base salary paid as severance shall be adjusted to match such restriction period. For example, we may opt to require only a 12-month restriction period, in which case, Mr. Gonzalez shall receive payment equal to that 12-month period.

General Release and Restrictive Covenants. In addition, the payment of all severance benefits to Mr. Gonzalez is subject to his delivering an executed and irrevocable confidential separation agreement and general release of claims and Mr. Gonzalez’s compliance with the following restrictive covenants:

Obligations in Connection with Death or Disability. Under the Gonzalez Employment Agreement, in the event of Mr. Gonzalez’s death or Disability (as defined in the Gonzalez Employment Agreement), the Company will provide Mr. Gonzalez with full vesting of any then-unvested, time-based equity awards, subject to the same general release and restrictive covenants provisions in the Gonzalez Employment Agreement for all other severance benefits.

The Keinan Employment Agreement, the Gonzalez Employment Agreement, and the Whitesell Employment Agreement each provide that any amounts payable under the employment agreements are subject to claw-back or disgorgement, to the extent applicable, under (i) the policies or any claw-back policy adopted by us, (ii) the Dodd-Frank Wall Street Reform and Consumer Protection Act, as amended, and rules, regulations, and binding, published guidance thereunder and (iii) the Sarbanes-Oxley Act of 2002.

In February 2025, the Compensation Committee approved performance bonuses with respect to year 2024 to Messrs. Keinan and Gonzalez of $792,000 and $888,102, respectively. Such bonuses were paid in late February 2025.

Our named executive officers did not participate in, or otherwise receive any benefits under, any pension or retirement plan or non-qualified deferred compensation plan sponsored by us during the years ended December 31, 2024 or 2023.

The following table presents information on all outstanding equity awards held by the Company’s named executive officers as of December 31, 2024.

Under Section 16(a) of the Exchange Act, all executive officers, directors, and each person who is the beneficial owner of more than 10% of the outstanding shares of a company that files reports pursuant to Section 12 of the Exchange Act, are required to report the ownership of such shares, options, and stock appreciation rights (other than certain cash-only rights) and any changes in that ownership with the SEC. Specific due dates for these reports have been established, and we are required to report, in this Proxy Statement, any failure to comply therewith during the fiscal year ended December 31, 2024.

Other than as set forth in the Delinquent Section 16(a) Reports section below, we believe that all of these filing requirements were satisfied by the Company’s executive officers, directors and by the beneficial owners of more than 10% of our Common Shares. In making this statement, we have relied solely on copies of any reporting forms received by us, and upon any written representations received from reporting persons that no Form 5 (Annual Statement of Changes in Beneficial Ownership) was required to be filed under applicable rules of the Commission.

We believe that there has been compliance with all Section 16(a) filing requirements except for Form 4 reflecting transactions for each of the following Section 16 officers to reflect shares of Restricted Stock Units withheld upon subsequent vesting. All of such RSUs were previously reported in full at the time such RSUs were granted, and, in all cases, the subsequent withholding was for the purpose of the payment of taxes upon the vesting of RSU shares: Tal Keinan (twenty-two withholding events); Francisco Gonzalez (thirty-six withholding events); Will Whitesell (one withholding event); and Michael W. Schmitt (thirty-six withholding events).

The following table sets forth information concerning the compensation of our non-employee directors for the year ended December 31, 2024. The compensation of Mr. Keinan, who is an employee of the Company, is fully reflected in the Summary Compensation Table and related discussion above. Mr. Keinan does not receive additional compensation for his service as a director.

Our director compensation plan provides that the non-executive directors of the Board receive annual compensation comprised of a cash retainer of $50,000 and an RSU award with an approximate grant date fair value of $70,000, subject to vesting conditions pursuant to the 2022 Plan. Non-executive directors are required to own $150,000 of our common stock by the third anniversary of their tenure. Further, these non-executive directors receive additional annual cash compensation for committee and Lead Independent Director service as follows:

The director compensation plan, including equity awards, retainer fees, as well as committee, chair, and meeting fees, is designed to attract and retain the most qualified individuals to serve on the Board and we believe is in line with that of other public companies of a similar size. The Board, on the recommendation of our Compensation Committee, is responsible for reviewing and approving any changes to the directors’ compensation arrangements.

As an emerging growth company, the Company will be exempt from certain requirements related to executive compensation, including the requirements to hold a nonbinding advisory vote on executive compensation and to provide information relating to the ratio of total compensation of the Company’s chief executive officer to the median of the annual total compensation of all of the Company’s employees, each as required by the Investor Protection and Securities Reform Act of 2010, which is part of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

The following table summarizes the securities authorized for issuance under our equity compensation plans at December 31, 2024:

The table below sets forth the aggregate fees billed by EA during the years ended December 31, 2024 and 2023.

The formal written charter for our Audit Committee requires that the Audit Committee (i) review and approve, in advance, the scope and plans for the audits and the audit fees and (ii) approve in advance (or, where permitted under the rules and regulations of the SEC, subsequently) all non-audit and tax services to be performed by the independent auditor that are not otherwise prohibited by law or regulations and any associated fees. Our Audit Committee may, in accordance with applicable law, establish pre-approval policies and procedures for the engagement of independent accountants to render services to the Company.

The material in this report is not “soliciting material,” is not deemed “filed” with the SEC and is not to be incorporated by reference in any filing of Sky Harbour Group Corporation under the Securities Act or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

The Audit Committee consists of the three non-employee directors named below and operates under a written charter adopted by our Board. Our Board annually reviews the NYSE’s listing standards definition of independence for Audit Committee members and has determined that each member of the Audit Committee meets that standard. Our Board has also determined that Mr. Jackson qualifies as an audit committee financial expert within the meaning of SEC regulations and meets the financial sophistication requirements of the NYSE.

The principal purpose of the Audit Committee is to assist our Board in its general oversight of our accounting and financial reporting processes and audits of our financial statements. The Audit Committee is responsible for selecting and engaging our independent auditor and approving the audit and non-audit services to be provided by the independent auditor. The Audit Committee’s function is more fully described in its charter, which our Board adopted and which the Audit Committee reviews on an annual basis.

In connection with the 2024 audit, in the performance of its oversight function, the Audit Committee reviewed and discussed with management the audited financial statements of the Company included in our Annual Report on Form 10-K for the years ended December 31, 2024 and 2023. The Audit Committee also discussed with the independent auditors of the Company for the year ended December 31, 2024 the matters required to be discussed by applicable requirements of the Public Company Accounting Oversight Board (the “PCAOB”) and approved by the SEC. The Audit Committee and received from and discussed with the independent auditor the written disclosures and the letter required by applicable requirements of the PCAOB regarding the independent auditor’s communications with the Audit Committee concerning independence.

Based upon the review and discussions referred to above, the Audit Committee recommended to the Board that the Company’s financial statements be included in the 2024 Annual Report on Form 10-K filed with the SEC on March 27, 2025.

Our Board currently consists of seven directors. The term of each our seven directors expires at the Annual Meeting.

Our Board has nominated Tal Keinan, Walter Jackson, Alethia Nancoo, Alex B. Rozek, Lysa Leiponis, Jordan Moelis, and Nick Wellmon for election at the Annual Meeting. If they are elected, they will serve on our Board until our 2026 Annual Meeting and until their respective successors have been elected and qualified. The nominees for director at the Annual Meeting, their ages as of March 31, 2025, and their positions and offices held with the Company are set forth below. Other biographical information for the members of our Board is set forth in this Proxy Statement under the heading “Directors, Executive Officers and Corporate Governance—Directors and Executive Officers.”

Certain of our stockholders who hold an aggregate of 53,195,564 shares of common stock as of the Record Date, April 22, 2025, have agreed to vote “FOR” each of the nominees listed in this Proxy Statement as a director.

Each person nominated for election has agreed to serve if elected. Directors are elected by a plurality of the votes properly cast in person or by proxy. This means that nominees receiving the highest number of “FOR” votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the nine nominees named below. However, if you are a street name stockholder, which means that your shares are held by a broker, bank or other nominee, your shares will not be voted for the election of directors unless you have provided voting instructions to your nominee.

We believe that the director nominees reflect a Board that is comprised of directors who (i) are predominantly independent, (ii) are of high integrity, (iii) have broad, business related knowledge and experience at the policy-making level in business, government, or technology, including their understanding of the Company’s industry and business in particular, (iv) have individual qualifications, relationships, and experience that would increase the overall effectiveness of the Board, (v) meet other requirements as may be required by applicable rules, such as financial literacy or financial expertise with respect to audit committee members, (vi) are committed to enhancing stockholder value, and (vii) have sufficient time to carry out their duties and to provide insight and practical wisdom based on experience. Specific experiences, qualifications, attributes or skills of nominees that contributed to our conclusion that the nominees should serve as directors are noted in their biographies. See “Directors, Executive Officers and Corporate Governance — Directors and Executive Officers.”

The Audit Committee appoints our independent registered public accounting firm. In this regard, the Audit Committee evaluates the qualifications, performance and independence of our independent registered public accounting firm and determines whether to re-engage our current firm. As part of its evaluation, the Audit Committee considers, among other factors, the quality and efficiency of the services provided by the firm, including the performance, technical expertise, industry knowledge and experience of the lead audit partner and the audit team assigned to our account; the overall strength and reputation of the firm; the firm’s global capabilities relative to our business; and the firm’s knowledge of our operations. Prior to the Yellowstone Transaction, EA served as Sky’s independent registered public accounting firm since 2019. Neither EA nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors and providing audit and permissible non-audit related services. Upon consideration of these and other factors, the Audit Committee has appointed EA to serve as our independent registered public accounting firm for the year ending December 31, 2025. Representatives of EA are expected to be present at the Annual Meeting, will have the opportunity to make a statement if such representatives desire to do so and will be available to respond to appropriate questions.

Neither our bylaws nor other governing documents or law require stockholder ratification of the selection of EA as our independent registered public accounting firm. However, the Board is submitting the selection of EA to the stockholders for ratification pursuant to the rules of the NYSE and as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of different independent auditors at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

The affirmative vote of the holders of a majority of the votes cast at the Annual Meeting will be required to ratify the appointment of EA as our independent registered public accounting firm for the fiscal year ending December 31, 2025. Abstentions and broker non-votes will be counted as present for purposes of determining the presence of a quorum but will not be considered as votes cast for or against this proposal and will therefore have no effect on the outcome of the vote.

Pursuant to Rule 14a-8 under the Exchange Act, some stockholder proposals may be eligible for including in the Company’s proxy statement for the 2026 Annual Meeting. To be considered for inclusion in next year’s proxy statement, stockholder proposals must be received by our Secretary at to our principal executive office, located at 136 Tower Road, Westchester County Airport, White Plains, New York 10604, no later than the close of business on January 6, 2026.Our bylaws provide notice procedures for stockholders to nominate a person as a director and to propose business to be considered by stockholders at an annual meeting outside the processes of Rule 14a-8. To be timely, a stockholder’s notice must be delivered to the Company at 136 Tower Road, Suite 205, Westchester County Airport, White Plains, NY 10604, not later than the close of business on the 90th day nor earlier than the opening of business on the 120th day before the anniversary date of the immediately preceding annual meeting of stockholders; provided, however, that in the event that the annual meeting is called for a date that is not within 30 days before or 60 days after such anniversary date, notice by the stockholder to be timely must be so received not later than the later of (x) the close of business on the 90th day before the meeting and (y) the close of business on the 10th day following the day on which public announcement of the date of the annual meeting was first made by the Company. Nominations and proposals also must satisfy other requirements set forth in the Bylaws. The Chairman of the Board may refuse to acknowledge the introduction of any stockholder proposal not made in compliance with the foregoing procedures. Assuming the date of the Annual Meeting is not so advanced or delayed, stockholders who wish to make a proposal at the 2026 Annual Meeting must notify us no earlier than February 20, 2026 and no later than March 21, 2026. Such notice must provide the information required by our bylaws with respect to each matter the stockholder proposes to bring before the 2026 Annual Meeting. You are advised to review our bylaws, which describe such information and other requirements about advance notice of stockholder proposals and director nominations. A copy of our current bylaws may be found on the investor relations page of our website at www.skyharbour.group.

In addition, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 of the Exchange Act no later than April 20, 2026.

If you reside at the same address as one or more of our stockholders, your broker, bank or other nominee may have sent you a notice explaining that your household will receive only one annual report and proxy statement for each company in which you hold stock through that broker, bank or other nominee. This practice of sending only one copy of proxy materials is known as “householding.” This procedure reduces printing costs and postage fees, and helps protect the environment as well. If you received a householding communication, only one copy of our Proxy Materials will be sent your address, unless contrary instructions were given by any stockholder at that address.

Upon written or oral request, we will promptly deliver a separate copy of the Proxy Materials to any stockholder at a shared address to which a single copy of documents was delivered. If you and another stockholder of record with whom you share an address participate in householding and you wish to receive an individual copy of our Proxy Materials now or discontinue your future participation in householding, please contact Broadridge Financial Solutions, Inc. toll-free at 1-866-540-7095 or by writing to Broadridge Financial Solutions, Inc., Attn: Householding Department, 51 Mercedes Way, Edgewood, NY 11717. Any stockholders who share the same address and currently receive multiple copies of our proxy materials who wish to receive only one copy in the future can contact their bank, broker or other nominee or our investor relations department at the address or telephone number listed above.

The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters as our Board may recommend.

It is important that your shares be represented at the Annual Meeting, regardless of the number of shares that you hold. You are, therefore, urged to vote at your earliest convenience on the Internet or by telephone as instructed, or by executing and returning a proxy card in the envelope provided.
