PROPOSALS TO BE VOTED ON BY BANKUNITED, INC. SHAREHOLDERS

PROPOSAL NO. 1

ELECTION OF DIRECTORS

Directors Elected Annually

Our Board of Directors is currently comprised of ten members. The size of the Board of Directors may be fixed from time to time exclusively by our Board of Directors as provided in our Certificate of Incorporation. BankUnited, Inc.'s directors are elected each year by the shareholders at the Company's annual meeting of shareholders. We do not have a staggered or classified board.

Nine director nominees are standing for election at this year's Annual Meeting. All nominees currently serve as directors on our Board of Directors. After many years of service on our Board, on April 1, 2024, Judge A. Gail Prudenti informed the Company that she would not be standing for reelection and her term will expire at this year's annual meeting of shareholders. Judge Prudenti’s decision is for personal reasons and not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies or practices. As a result, the Board of Directors expects to reduce the size of the Board of Directors to nine members shortly following this year's annual meeting of shareholders. Each elected director's term will last until the 2025 annual meeting of shareholders and until such director's successor is duly elected and qualified, or until such director's earlier death, resignation or removal.

Directors of BankUnited, Inc. have historically also served as directors of its wholly-owned subsidiary BankUnited, N.A. (the "Bank"). 

Each director will be elected by a majority of the votes cast, either in person or by properly authorized proxy, in the election of directors at the Annual Meeting.

Under our Amended and Restated By-Laws, at any meeting of the shareholders at which directors are to be elected and a quorum is present, each director nominee receiving a majority of the votes cast at the meeting will be elected as a director. A majority of votes cast means that the number of shares voted “for” a director’s election exceeds 50% of the number of votes cast with respect to that director’s election. Abstentions and broker non-votes will have no effect on the election of directors.

If a nominee for director who is an incumbent director is not elected and no successor has been elected at the meeting, then the director will be required under our Amended and Restated By-Laws to promptly tender his or her resignation as a director. Our Nominating and Corporate Governance Committee would then make a recommendation to the full Board as to whether to accept or reject the resignation.

If the resignation is not accepted by the Board, then the director will continue to serve until the next annual meeting and until his or her successor is duly elected, or his or her earlier death, resignation or removal.

If the director’s resignation is accepted by the Board, then the Board may fill the vacancy.

However, if the number of nominees exceeds the number of positions available for the election of directors, then the directors will be elected by a plurality of the votes cast at any meeting of the shareholders at which directors are to be elected and a quorum is present.

BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Role of Board of Directors

The Company's business and affairs are managed under the direction and oversight of the Board of Directors, which is the Company's ultimate decision-making body, except with respect to those matters reserved to the Company's shareholders. The Board of Directors' mission is to maximize long-term shareholder value. The Board of Directors establishes the Company's overall corporate policies and risk appetite, evaluates the Company's Chief Executive Officer ("CEO") and the senior leadership team and acts as an advisor and counselor to senior management. The Board of Directors also oversees the Company's business strategy, planning and risk management framework, as well as the performance of management in executing the Company's business strategy, assessing and managing risks and managing the Company's day-to-day operations.

Director Independence

Under the New York Stock Exchange ("NYSE") listing standards, in order to consider a director independent, the Board of Directors must affirmatively determine that he or she has no material relationship with the Company. The standards specify the criteria for determining whether directors are independent and contain guidelines for directors and their immediate family members with respect to employment or affiliation with the Company or its independent registered public accounting firm. The Board of Directors also has adopted independence standards to assist it in making independence determinations. The Company's Director Independence Standards contain the formal director qualification and independence standards adopted by the Board of Directors, and are available as part of the Company's Corporate Governance Guidelines on the Company's website at https://ir.bankunited.com.

The Board of Directors determines annually whether a director is independent at the time the Board of Directors approves director nominations for inclusion in the Company's proxy statement and when a director joins the Board of Directors between annual meetings. Although the determination of whether a director is independent relies on the Board's subjective assessment of all of the relevant facts and circumstances, the Company's Director Independence Standards provide that a director will not qualify as independent if:

within the last three years, (i) the director has been an employee of the Company or an immediate family member of the director has been an executive officer of the Company; (ii) the director or an immediate family member of the director has received, during any twelve-month period, more than $120,000 in direct compensation from the Company, other than director and committee fees and pension or other deferred compensation for prior service (provided that such compensation is not contingent in any way on continued service) and compensation received by a family member for service as a non-executive employee of the Company; (iii) the director or an immediate family member of the director was a partner or employee of the Company's independent registered public accounting firm and personally worked on the Company's audit within that time; or (iv) the director or an immediate family member of the director has been employed as an executive officer of a company in which a present executive officer of the Company at the same time served on the compensation committee of that company's board of directors;

the director is a current partner or employee of the Company's independent registered public accounting firm or an immediate family member of the director is a current partner of such firm or a current employee of such firm who personally works on the Company's audit; or

the director or an immediate family member of the director is a current executive officer of a company that has made payments to, or received payments from, the Company for property or services in an

14

BankUnited, Inc. 2024 Proxy Statement

amount which, in any of the last three fiscal years, exceeds the greater of $1 million or 2% of such company's consolidated gross revenue.

The Board undertook its annual review of director independence in April 2024. As a result of this review, the Board affirmatively determined that all of the directors and nominees are independent of the Company and its management under the corporate governance standards of the NYSE and the Company's Director Independence Standards, with the exception of Rajinder P. Singh. Mr. Singh is our Chairman, President and Chief Executive Officer. In making the determination that Mr. Rubenstein is independent of the Company and its management, the Board of Directors considered that Mr. Rubenstein is a retired partner of the law firm Skadden, Arps, Slate, Meagher and Flom, LLP. Skadden currently provides and may in the future provide certain legal services to us and our affiliates, for which it has received, or may receive, customary compensation, fees and expense reimbursement. In determining Dr. Smith Baugh's independence from the Company and its management, the Board of Directors considered that Dr. Smith Baugh, is the President and CEO of the Urban League of Broward County, a 501(c)(3) nonprofit organization in the State of Florida. BankUnited, N.A. has in the past in the ordinary course of business provided certain contributions and financial support to the Urban League of Broward County and its affiliated community development funds, none of which require reporting under the NYSE independence standard or were deemed material by the Board.

Board and Board Committee Performance Evaluations

Each year, the Nominating and Corporate Governance Committee leads the Board through self-evaluation. Through this evaluation process, the directors assess performance, identify areas for improvement and provide feedback.

Board Annual Self-Evaluation:

•Each director completes an open-ended questionnaire with key topics such as board composition and culture; information and resources; effectiveness and oversight;

•Responses are reviewed by the Chair of the Nominating and Corporate Governance Committee;

•The Chair of the Nominating and Corporate Governance Committee leads a discussion of the results with the full Board at the next Board meeting;

•As a result of director feedback, management has updated content and formats of some materials provided to the Board as well as provided training sessions on new regulatory requirements, disclosures and other relevant matters.

Committee Annual Self-Evaluations:

•Each director completes an open-ended questionnaire for each committee on which he or she serves with key topics such as Committee Charter, structure, composition and effectiveness;

•Responses are reviewed by each Committee Chair;

•Each Committee Chair leads a discussion of the results with the full Board at the next Board meeting.

Director Education

Our Board believes that director education is essential to the ability of our directors to provide oversight and fulfill their roles. The Nominating and Corporate Governance Committee provides directors with information regarding external director development and training programs and encourages director participation in such programs. Continuing director education is provided during Board meetings by both internal and external subject

15

BankUnited, Inc. 2024 Proxy Statement

matter experts and our directors also attend conferences and round tables hosted by our primary banking regulators. Some of the topics on which our Board receives regular education include regulatory compliance, Bank Secrecy Act ("BSA")/Anti-Money Laundering ("AML") and cybersecurity.

Board of Directors Meetings and Attendance

In 2023, the Board of Directors held ten meetings and acted by written consent four times. Each director attended 75% or more of the meetings of the Board of Directors and Board committees on which they served during 2023. Directors are expected to attend all meetings of shareholders. All directors attended the 2023 annual meeting.

BankUnited, Inc. 2024 Proxy Statement

None of our executive officers serves or has served as a member of the board of directors, compensation committee or other board committee performing equivalent functions of any entity that has one or more executive officers serving as one of our directors or on our Compensation Committee.

Risk Governance Documents

The Company's Risk Appetite Statement, which is reviewed and approved by the Risk Committee, sets forth guidelines for the aggregate levels of acceptable risk across multiple dimensions and forms the basis of the Company's enterprise risk management framework. It further defines the boundaries for the type and amount of risk that may be undertaken by the Company in pursuing business objectives and initiatives.

    The Company's Risk Management Framework establishes enterprise-wide governance and risk management requirements for monitoring nine categories of risk: strategic risk, credit risk, interest rate risk, liquidity risk, operational risk, compliance risk, BSA/AML risk, reputation risk and price risk.

Risk Management and Oversight

    Our Board of Directors oversees our "three lines of defense" risk management framework, including the company-wide approach to risk management, carried out by our management. Our full Board of Directors determines the appropriate levels of risk for the Company generally, assesses the specific risks faced by us and reviews the steps taken by management to manage those risks. While our full Board of Directors maintains the ultimate oversight responsibility for risk management, its committees oversee risk in certain specified areas.

In particular, the Risk Committee plays a key role in the Board of Directors' exercise of its risk oversight function. The Risk Committee assists the Board in overseeing the Company's enterprise-wide risk management framework, including the risk appetite statement, risk tolerances and limits, and risk management infrastructure. The Risk Committee oversees the risk assessment process to assist the Board and management in identifying emerging risks that could potentially impact the Company's strategic objectives and business plan and provides oversight of certain elements of ESG related risk, including information security and climate related risks. The Risk Committee reviews regular reporting related to credit, interest rate, liquidity, operational, BSA/AML and compliance risk.

The Audit Committee also has a significant role in the Board of Directors' exercise of its risk oversight responsibilities. The Audit Committee is primarily responsible for overseeing matters involving the Company's financial reporting risks and the guidelines, policies and processes for managing such risks, including internal controls over financial reporting. The Audit Committee conducts its risk oversight in a variety of ways, including reviewing management's assessment of the Company's internal control over financial reporting, and reviewing and approving the Company's significant accounting policies. Additionally, the Company's independent registered public accounting firm regularly discusses risks and related mitigation measures that may come to their attention during its regular reviews and audits of the Company's financial statements with the Audit Committee. To ensure candid and complete reporting, the Audit Committee regularly meets in separate executive sessions with management, the head of the Company's internal audit department and the Company's independent registered public accounting firm.

The Compensation Committee is responsible for overseeing the management of risks relating to our executive compensation plans and practices, as well as the incentives created by the compensation awards it administers. The Compensation Committee reviews our incentive plans to ensure that they appropriately balance risk and reward and do not encourage inappropriate risk taking, which could impact our financial position and reputation.

19

BankUnited, Inc. 2024 Proxy Statement

The Nominating and Corporate Governance Committee is responsible for overseeing the management of risks associated with the independence and composition of our Board.

The Board of Directors has delegated certain risk management functions to specific management level committees. The primary role of these committees is to oversee the operational implementation of our business strategies and objectives and ensure alignment with the Board's stated risk appetite.

Pursuant to our Board's instruction, management regularly reports on applicable risks to the relevant committee or the full Board, as appropriate, with additional review or reporting on risks conducted as needed or as requested by our Board and its committees.

Business Continuity

The Company has a Business Continuity Management ("BCM") Policy governing the oversight and implementation of the Company's resilience, continuity and response capabilities during business interruptions impacting our operations, systems, services or employees. The Policy is supported by the BCM Program.The BCM program incorporates four interconnected components - business continuity, crisis management, IT recovery and resilience testing. These components are designed to identify, manage and adequately respond to the impact of potential events that could disrupt our operations and systems or adversely affect the well-being of our employees. The foundation of the business continuity risk management framework includes risk assessment and business impact analysis. The BCM department also assesses the resilience of our significant third party service providers, including assessing the ability to respond to service disruptions or degradations resulting from natural disasters or cyber-security incidents.

20

BankUnited, Inc. 2024 Proxy Statement

Compliance

Compliance risk is the risk to current or projected financial condition and resilience arising from violations of laws or regulations, or from nonconformance with prescribed practices, internal policies and procedures, or ethical standards. The Company has a dedicated compliance function, headed by the Chief Compliance Officer, that promotes a disciplined risk culture and monitors and facilitates compliance with applicable laws and regulations, as well as regulatory expectations articulated in formal guidance by the banking regulators. The Company’s compliance management program includes risk-based testing and monitoring programs, issue identification and reporting, and regulatory change management. Quarterly updates on the compliance program are provided to the Board Risk Committee. The compliance department develops and delivers a comprehensive bank-wide employee training program tailored to job functions, focused on applicable laws and regulations including consumer protection, fair lending, and the Community Reinvestment Act.

BSA/AML/Office of Foreign Assets Control (“OFAC”)

The Company has established and maintains an enterprise-wide BSA/AML/OFAC Policy and Program to ensure that we are in compliance with applicable laws, rules and regulations related to money laundering and terrorist financing activities, sanctions programs and rules administered and enforced by the U.S. Treasury Department’s Office of Foreign Assets Control. The Bank has designated a BSA/OFAC Officer responsible for coordinating and monitoring day-to-day compliance with the BSA/AML/OFAC Policy and Program and applicable laws, rules and regulations. As part of the program, the Financial Crimes Compliance Committee provides cross-business line executive level oversight of the Bank’s compliance with the BSA/AML/OFAC Policy and Program and is chaired by the BSA/OFAC Officer.

Shareholder Engagement

We engage with our shareholders throughout the year, not just during proxy season. We regularly have discussions with shareholders, potential shareholders, proxy advisory services, rating agencies and investment analysts. Our executive management team participates in investor conferences and other industry conferences. The Board reviews shareholder feedback, which helps shape our policies and practices.

Throughout 2023, we held virtual and telephonic meetings with many of our shareholders. We further held in-person meetings with shareholders representing approximately 30% of our outstanding shares and met with potential investors while attending eight investor conferences. These meetings help us to address corporate governance matters, diversity, corporate strategy, risk management and current trends.

The Board recognizes the value of developing and maintaining strong relationships with our investors and understanding their perspectives. Mr. Pauls, our Lead Independent Director, participates in some meetings and discusses investor feedback with the full board. Investor views and priorities assist the Board in gathering information and making balanced decisions in the best interests of the Company and its shareholders.

21

BankUnited, Inc. 2024 Proxy Statement

Board Leadership Structure

The Board of Directors is responsible for overseeing the exercise of corporate power and seeing that our business and affairs are managed to meet our stated goals and objectives and that the long-term interests of our shareholders are served. The Board of Directors regularly reviews and assesses the effectiveness of the Company's leadership structure in the context of the Company's specific circumstances, culture, strategic objectives and challenges.

The Board of Directors does not have a fixed policy regarding the separation of the offices of Chairman and CEO because it believes that it should maintain flexibility to select the Chairman and determine the Board leadership structure, from time to time, based on criteria that it deems to be in the best interests of the Company and its shareholders.

Our current board leadership structure provides for a combined role of the Chairman of the Board and CEO, along with a Lead Independent Director and the independence of all other directors. The independent directors believe that Mr. Singh's knowledge and background with the Company, his deep industry experience and his demonstrated leadership capability benefits our shareholders and employees and that a combined role of Chairman and CEO will best allow us to execute our strategic initiatives and business plan at this time.

Lead Independent Director

The Board of Directors has appointed Mr. Pauls to serve as our Lead Independent Director. Mr. Pauls brings extensive banking and risk management experience to our Board, is an independent voice on important issues facing the Company and ensures that those issues are fully considered by the Board of Directors.

Primary Responsibilities: In his role as Lead Independent Director, Mr. Pauls' duties include, but are not limited to:

•Presiding over regularly scheduled executive sessions with the non-management directors;

•Serving as a liaison between the Board and senior management;

•Assisting the Board of Directors, our Nominating and Corporate Governance Committee and executive management to ensure compliance with the Company's Corporate Governance Guidelines;

•Assisting the Nominating and Corporate Governance Committee and the CEO in the identification and evaluation of director candidates;

•Participating with management in shareholder engagement meetings and sharing feedback with the full Board (see "Shareholder Engagement" on page 21 for information on our shareholder engagement program);

•Communicating, as appropriate, with our primary bank regulators.

Our Corporate Governance Guidelines provide for additional independent oversight of our operations, risks, business strategy and compensation practices. Consistent with our Corporate Governance Guidelines, the Board of Directors currently consists of independent directors, except for Mr. Singh. Each of the Audit Committee, Risk Committee, Compensation Committee and Nominating and Corporate Governance Committee is composed solely of independent directors. Independent directors, therefore, oversee essential, risk-sensitive matters such as the quality and integrity of our financial statements; the compensation of our named executive officers, including the CEO; the nomination of directors; and the evaluation of the Board, its committees, and its members.

22

BankUnited, Inc. 2024 Proxy Statement

Our Corporate Governance Guidelines also require that the non-management directors meet regularly in executive session without the presence of management, which provides an opportunity for the independent directors to freely express their views on important issues.

Through the Company's overall governance structure described above, the Board of Directors believes it has effectively balanced the need for strategic leadership by the Company's Chairman and CEO with the oversight and objectivity of the independent directors and has created an effective and appropriate leadership structure that is conducive to the risk oversight process. The Board of Directors recognizes that, depending on the circumstances, other leadership structures might be appropriate and in the best interests of the Company. Accordingly, the Board of Directors has the discretion to modify the Company's leadership structure if it believes doing so would be in the best interests of the Company.

Executive Sessions

The rules of the NYSE require the non-management directors of the Company to regularly meet in executive session without management. In 2023, non-management directors of the Company met in executive session four times. The Company's Corporate Governance Guidelines state that a non-management independent director shall be chosen to preside at each executive session. Mr. Pauls currently serves as the Presiding Director. For information regarding how to communicate with non-management directors as a group and one or more individual members of the Board, including the Presiding Director, see "Communications with the Board of Directors" below.

CEO and Senior Management Succession Planning

    Our Nominating and Corporate Governance Committee has responsibility for succession planning with respect to the Company's CEO, as well as oversight of succession planning for other executive management positions. The Nominating and Corporate Governance Committee annually reviews succession plans for the CEO, and considers emergency, interim scenarios as well as long-term scenarios. The Nominating and Corporate Governance Committee further works with our CEO to review succession planning for other executive management positions, including his evaluations of executive officers and development plans for executives. The Chair of the Nominating and Corporate Governance Committee leads a discussion with the full Board following the annual succession planning session.

23

BankUnited, Inc. 2024 Proxy Statement

Communications with the Board of Directors

Any interested parties desiring to communicate with the Board of Directors or any of the independent directors regarding the Company may directly contact such directors by delivering such correspondence to such directors (or the entire Board) in care of the Company's Corporate Secretary at BankUnited, Inc., 14817 Oak Lane, Miami Lakes, FL 33016.

The Audit Committee of the Board of Directors has established procedures for the receipt, retention and treatment of complaints received by us regarding accounting, internal control over financial reporting and auditing matters and the confidential, anonymous submission by our employees of concerns regarding questionable accounting or auditing matters. Persons wishing to communicate with the Audit Committee may do so by writing in care of the Chairman, Audit Committee, BankUnited, Inc., 14817 Oak Lane, Miami Lakes, FL 33016.

Corporate Governance Guidelines, Code of Conduct and Code of Ethics

Our Board has adopted Corporate Governance Guidelines, which set forth a flexible framework within which our Board, assisted by Board committees, directs the affairs of the Company. The Corporate Governance Guidelines address, among other things, the composition and functions of the Board, director independence, compensation of directors, management succession and review, Board committees and selection of new directors.

We also have a Code of Conduct, which is applicable to all directors, officers, employees, agents (including consultants and contractors) and temporary personnel of the Company. We have a separate Code of Ethics for Principal Executive and Senior Financial Officers, which contains provisions specifically applicable to our principal executive officer, principal financial officer, principal accounting officer and controller (or persons performing similar functions).

We have an Ethics Committee, formed to oversee and help define a culture of ethical responsibility. The ethics committee reports periodically to the Audit Committee of the Board. The Company also has a 24 hour ethics hotline which can be used to report suspected violations of the Code of Conduct, accounting, audit or internal accounting control matters. The Company encourages any employee to report such conduct openly, if desired, or anonymously, without fear of retaliation.

The Corporate Governance Guidelines, the Code of Conduct and the Code of Ethics for Principal Executive and Senior Financial Officers are available on our website at https://ir.bankunited.com. We expect that any amendments to these codes, or any waivers of their requirements, will be disclosed on our website.

ESG Practices and Oversight

The Board of Directors oversees ESG matters and has delegated primary responsibility for oversight of those matters, including human capital and diversity, to the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee periodically reports to the full Board on material ESG matters. Our Risk Committee also has oversight for certain ESG related risks. In addition to its oversight of information security and cybersecurity, the Risk Committee, as part of the Company's enterprise-wide risk management framework is responsible for oversight of the identification and mitigation of climate related risks such as those related to credit underwriting and severe weather events. The Compensation Committee may also be involved with oversight of certain human capital matters.

BankUnited, Inc. 2024 Proxy Statement

Environmental Sustainability

We recognize that the world’s climate is changing. Climate change is likely to have profound long-term impacts on our way of life, our communities and more specifically on the way we do business. We recognize that BankUnited operates in and has exposure to areas of the country that may be more exposed to climate change risk over the long-term. While we recognize that the science related to predicting and estimating the long-term impacts of climate change is relatively new and still evolving, we strive to incorporate consideration of climate change risk in our strategic and business decisions.

We continue to monitor the evolution of regulatory developments and industry practice with a view toward developing a more comprehensive framework for assessing, monitoring and managing the impact or potential impact of both physical and transition climate risk on our business. We are currently investing in efforts to help us better dimension the potential impact of climate change on our business and provide more comprehensive disclosures to our stakeholders.

Our BCM department actively monitors severe weather events that may impact the Company's customers, locations or operations including hurricanes, winter storms, flooding and fire. Given our presence in Florida, during hurricane season BCM continuously monitors and tracks storm activity and forecasted paths. The Company has a comprehensive Hurricane Response Plan that outlines measures to be taken before, during and after a storm strikes, including customer outreach, communication plans, evacuation and employee safety, safeguarding real estate assets, activation of a command center, the relocation of staff responsible for critical business processes if necessary and post storm impact assessments on both the Company and its customers. This plan has been tested under both simulated and actual conditions. BCM also assesses the resilience of our significant third party service providers with respect to their ability to respond to service disruptions or degradations resulting from severe weather events. We have migrated our disaster recovery technology infrastructure as well as most of the technology infrastructure supporting daily operations to the cloud to minimize the impact of physical damage to our facilities on our ability to continue uninterrupted operations. Our credit underwriting standards also consider weather event related risks, including risks related to the cost and availability to our borrowers of property and casualty insurance.

We view providing financing that promotes sustainable and environmentally friendly practices as prudent and desirable. We have a dedicated sustainability finance practice in our corporate banking division charged with identifying and furthering these opportunities. At December 31, 2023, our loan portfolio contained $751 million of loans in the categories of renewable energy, energy efficiency, clean transportation, sustainable water, water and waste management, environmental remediation, carbon capture, climate change adaptation, emissions and greenhouse gas reduction, fleet transformation and the financing of energy efficient or LEED certified properties. Our securities portfolio currently contains approximately $321 million in bonds designated by the issuer as green, social or sustainability bonds.

Information Security and Cybersecurity

The Company has a formal information security program and charter, designed to ensure that its information assets are protected in a manner that reduces the risk of unauthorized information disclosure, modification or destruction, whether accidental or intentional. The information security program applies to all employees, contractors and third party service providers, establishes standards and practices for the secure use and management of the Company's data, information and information systems and is consistent with applicable regulatory guidelines and principles. The program requires the identification and assessment of and appropriate response to vulnerabilities and threats that could adversely impact the Company's information and/or data assets.

25

BankUnited, Inc. 2024 Proxy Statement

Our information security organization is led by our Chief Information Security Officer ("CISO"), who has primary responsibility for establishing, maintaining and overseeing the enterprise-wide information security program. The CISO reports administratively to our Chief Information Officer, who reports directly to our CEO. The CISO also has a direct line of reporting to the Risk Committee of the Board. While our information security organization has primary responsibility for the monitoring, detection and containment of internal and external security threats, information security is a shared responsibility. Platform owners and information owners also play critical roles in our information security infrastructure.

The Operational Risk Management Committee oversees information security risk management. The Risk Committee of the Board has board level responsibility for risk oversight related to information security and cybersecurity, for overseeing management's approach to effectively addressing these risks and for reviewing the Information Security Program at least annually. The Risk Committee, and as appropriate the full Board, receive regular reporting from the CISO.

Our information security department, in collaboration with our third-party risk management unit,     evaluates the information technology and security programs of significant third party service providers. These reviews typically leverage current SOC 1 or SOC 2 reports that evaluate the design and operational effectiveness of information technology and security related controls. In addition, the third party’s information technology and security policies and procedures are evaluated to form an overall opinion of the third party service provider's technology and information security posture. Our BCM department assesses the resilience, incident reporting and management capabilities of our significant third party service providers with respect to service disruptions or degradations resulting from information security incidents.

We provide regular and continuous cybersecurity training and education to our employees with a goal of educating them on how to detect potential threats and on their responsibilities to help protect the confidentiality, availability and integrity of the Company's information assets, thereby creating a security aware culture. Engaging our employees with security awareness throughout the year, focusing on behavior at both the office and remote work locations, helps to maintain a high level of security awareness. Our cybersecurity training program consists of new-hire training, monthly newsletters, security tips and videos, regular simulated phishing campaigns directed at all of our employees, a "repeat clicker" program required for employees who click on phishing emails after receiving required training, an annual cybersecurity awareness month, a recognition program, gamification exercises and required annual compliance training for all employees. Our board members also participate in cybersecurity training presented by both internal and external subject matter experts, including presentations and reporting related to emerging cybersecurity and information security matters, and updates on technology, regulatory and legal developments.

We think it is important to measure employee engagement; our most recent employee engagement survey was conducted by a third party in September 2022. Survey results reported an increase in overall engagement, defined as employees who responded favorably, from 73% in 2020 to 81% in 2022. The 81% overall engagement score in 2022 favorably compared to an industry benchmark of 76%. Survey results also reported that 93% of our team members feel that they are treated with respect at BankUnited and 91% feel that BankUnited employees are treated equally regardless of race, ethnicity, age, gender disability, religious beliefs, and sexual orientation.

Director Compensation

We use a combination of cash and stock-based incentive compensation to attract and retain independent, qualified candidates to serve on our Board. In setting director compensation, we consider the significant amount of time that directors expend in fulfilling their duties, as well as the skill level we require of members of our Board. Directors who are also our employees do not receive any compensation from us for any period of service on our Board or Board committees that is concurrent with service as an employee.

Directors do not receive fees for attending Board or committee meetings. Non-employee directors are reimbursed for reasonable expenses incurred in connection with Board-related activities.

2023 Director Compensation

Our Compensation Committee periodically reviews and recommends updates to the director compensation program for Board approval. No changes were made to the form or amount of director compensation for 2023.

Cash-Based Compensation

For service in 2023, each non-employee director was eligible to receive an annual cash retainer of $70,000 for his or her service on our Board. The Chairs of the Audit Committee and the Risk Committee each receive an additional annual retainer of $35,000 and the members of the Audit and the Risk committees receive an additional annual retainer of $25,000. The Chairs of the Compensation Committee and the Nominating and Corporate Governance Committee each receive an additional annual retainer of $25,000. Cash retainers are paid in monthly or quarterly installments.

Stock retention requirements and non-hedging policy for our non-management directors

All non-management directors subject to the policy are in compliance with these requirements. Dr. Smith Baugh joined the Board in May 2023 and has three years to comply with the retention requirement.

•The Company's Insider Trading Policy prohibits directors and executive officers of the Company from engaging in short sales of the Company's securities and from engaging in hedging transactions such as (but not limited to) zero-cost collars, equity swaps, and forward sale contracts in the Company's securities.

Director Nominating Process and Diversity

The Board of Directors is responsible for nominating members for election to the Board of Directors and for filling vacancies on the Board of Directors that may occur between annual meetings of shareholders. The Nominating and Corporate Governance Committee is responsible for identifying, screening and recommending

32

BankUnited, Inc. 2024 Proxy Statement

candidates to the Board of Directors for Board membership. When formulating its Board of Directors membership recommendations, the Nominating and Corporate Governance Committee may also consider advice and recommendations from others, including shareholders, as it deems appropriate.

The Nominating and Corporate Governance Committee and the Board of Directors believe that diversity along multiple dimensions, including opinions, skills, perspectives, personal and professional experiences and other differentiating characteristics, is an important element of nomination for Board membership. Our director nominees are 33% diverse by gender (female) and 44% diverse by ethnicity/nationality. The Nominating and Corporate Governance Committee has not identified any specific minimum qualifications that must be met for a person to be considered as a candidate for director. However, Board candidates are selected based on various criteria including experience, skills, expertise, diversity, personal and professional integrity, character, business judgment, time availability in light of other commitments, dedication, conflicts of interest and such other relevant factors that the Nominating and Corporate Governance Committee considers appropriate in the context of the needs of the Board of Directors. Although the Board of Directors does not have a formal diversity policy, the Nominating and Corporate Governance Committee and Board of Directors review these factors, including diversity, in considering candidates for board membership. Board members are expected to prepare for, attend and participate in all Board of Directors and applicable committee meetings and the Company's annual meetings of shareholders.

Candidates Nominated by Shareholders

The Nominating and Corporate Governance Committee will also consider nominees recommended by shareholders. Our Corporate Governance Guidelines provide that nominees recommended by shareholders should be given appropriate consideration in the same manner as other nominees.

The

33

notice must also include a representation that the shareholder giving the notice intends to appear in person or by proxy at the 2025 annual meeting to nominate the person named in the notice.

The Company's Amended and Restated By-Laws also require that the notice provide certain information regarding the candidate whom the Nominating Person proposes to nominate as a director, including (i) certain biographical information, such as name, age, business and residential address and principal occupation, (ii) the information that would be required to be provided if the candidate were a Nominating Person, (iii) a resume or other written statement of the qualifications of the candidate and (iv) all other information regarding the candidate, including the written consent of the candidate indicating that the candidate is willing to be named in the proxy statement as a nominee and serve as a director if elected, that would be required to be disclosed in a proxy statement or other filings made with the SEC in connection with the solicitation of proxies for director elections.

For a complete description of the procedures and disclosure requirements to be complied with by shareholders in connection with submitting director nominations, shareholders should refer to the Company's Amended and Restated By-Laws.

CERTAIN RELATED PARTY RELATIONSHIPS

Review and Approval of Transactions with Related Persons

Transactions by us with related parties are subject to a formal written policy, as well as regulatory requirements and restrictions. These requirements and restrictions include Sections 23A and 23B of the Federal Reserve Act (which govern certain transactions by the Bank with its affiliates) and the Federal Reserve's Regulation O (which governs certain loans by the Bank to its executive officers, directors and principal shareholders). We have adopted policies to comply with these regulatory requirements and restrictions.

Our Board of Directors has also adopted a written policy governing the approval of related party transactions that complies with all applicable requirements of the SEC and the NYSE concerning related party transactions. Related party transactions are transactions in which our Company is a participant, the amount involved exceeds $120,000 and a related party has or will have a direct or indirect material interest. Related parties of our Company include directors (including nominees for election as directors), executive officers, greater than 5% shareholders of our Company and the immediate family members of these persons. Our general counsel, in consultation with management and outside counsel, as appropriate, will review potential related party transactions to determine if they are subject to our Related Party Transactions Policy. If so, the transaction will be referred for approval or ratification to the Nominating and Corporate Governance Committee. In determining whether to approve a related party transaction, the Nominating and Corporate Governance Committee will consider, among other factors, the fairness of the proposed transaction; the direct or indirect nature of the director's, executive officer's or related party's interest in the transaction; the appearance of an improper conflict of interest for any director or executive officer of the Company, taking into account the size of the transaction and the financial position of the director, executive officer or related party; whether the transaction would impair an outside director's independence; the acceptability of the transaction to the Company's regulators; and the potential violations of other Company policies. Additionally, all related party transactions are reviewed by the Audit Committee. Our Related Party Transactions Policy is available on our website at https://ir.bankunited.com, as Annex B to our Corporate Governance Guidelines.

The Company had no reportable related party transactions as defined in the applicable policy for 2023 or to date in 2024 and there are no currently proposed related party transactions that would be reportable under the applicable policy.

PROPOSAL NO. 2

RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Proposal

The Audit Committee has appointed Deloitte & Touche LLP to serve as BankUnited, Inc.'s independent registered public accounting firm for its fiscal year ending December 31, 2024. The Audit Committee and the Board of Directors seek to have the shareholders ratify the Audit Committee's appointment of Deloitte & Touche LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2024. Although BankUnited, Inc. is not required to seek shareholder approval of this appointment, the Board of Directors believes it to be sound corporate governance to do so. If the appointment of Deloitte & Touche LLP is not ratified by the shareholders, the Audit Committee may appoint another independent registered public accounting firm or may decide to maintain its appointment of Deloitte & Touche LLP.

Representatives of Deloitte & Touche LLP will be present at the Annual Meeting and will have the opportunity to make a statement, if they desire to do so, and to respond to appropriate questions.

OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" RATIFICATION OF THE REGISTERED INDEPENDENT PUBLIC ACCOUNTING FIRM FOR 2024.

Report of the Audit Committee

The information contained in this report shall not be deemed to be "soliciting material" or "filed" with the SEC or subject to the liabilities of Section 18 of the Exchange Act, except to the extent that the Company specifically incorporates it by reference into a document filed under the Securities Act or the Exchange Act.

The Audit Committee oversees the Company's financial reporting process on behalf of the Board of Directors. The Audit Committee consists of three directors who have been determined by the Board of Directors to be independent of the Company as prescribed by the NYSE and the SEC. Our Board has further determined that all Committee members are financially literate in accordance with NYSE listing standards and further qualify as "audit committee financial experts" as defined by the SEC. The Company's management has the primary responsibility for the financial statements and for the financial reporting process, including the establishment and maintenance of the system of internal control over financial reporting. Deloitte & Touche LLP, the Company's independent registered public accounting firm for the fiscal year ended December 31, 2023, was responsible for auditing the financial statements prepared by management, expressing an opinion on the conformity of those audited financial statements with U.S. generally accepted accounting principles and auditing the Company's internal control over financial reporting and expressing an opinion on the effectiveness thereof. In this context, the Audit Committee has reviewed the audited financial statements and met and held discussions with management and Deloitte & Touche LLP regarding the fair and complete presentation of those financial statements and the assessment of the Company's internal control over financial reporting.

The Audit Committee has discussed with Deloitte & Touche LLP matters required to be discussed by Auditing Standard No. 1301, as adopted by the Public Company Accounting Oversight Board (the "PCAOB") and has reviewed and discussed Deloitte & Touche LLP's independence from the Company and its management. As part of that review, the Audit Committee has received the required written disclosures and correspondence required by applicable requirements of the PCAOB regarding Deloitte & Touche LLP's communications with the Audit Committee concerning independence. The Audit Committee has concluded that Deloitte & Touche LLP is independent from the Company and its management.

The Audit Committee meets with the Chief Financial Officer in regular sessions and has met with representatives of Deloitte & Touche LLP, in regular and executive sessions, to discuss the results of their examinations, the evaluations of the Company's internal controls and the overall quality of the Company's financial reporting.

In reliance on the reviews and discussions referred to above, the Audit Committee has recommended to the Board of Directors, and the Board has approved, that the audited financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, for filing with the SEC.

EXECUTIVE SUMMARY

Building Long-Term Value for our Shareholders in a Challenging Environment

2023 Key Performance Highlights

2023 was a challenging year for the banking industry, characterized by an unprecedented interest rate environment, restrictive monetary policy and a liquidity event that led to three highly publicized regional bank closures. Our executive management team and board of directors successfully navigated this challenging environment and BankUnited continued to support its customers and serve their banking needs. The Company finished the year strong with robust loan and deposit pipelines, an improved funding mix, strong credit performance and an expanding margin.

Net income for the year ended December 31, 2023 was $178.7 million compared to $285.0 million for the year ended December 31, 2022. For the year ended December 31, 2023, the return on average stockholders' equity was 7.01% and the return on average assets was 0.49%. Earnings for the year were negatively impacted by margin pressure resulting from the cumulative impact of a series of events that have shaped the operating environment and by a $35.4 million FDIC special assessment. Despite these factors, the Company gained strong momentum in 2023 on the execution of near to medium-term strategic priorities that support our long-term vision of building a leading, relationship focused small business and middle market franchise. Those strategic priorities include improving both the funding profile and the asset mix, ultimately leading to margin expansion, while maintaining strong liquidity, capital and credit quality.

•The funding mix improved over the final three quarters of 2023 following the industry liquidity event of March; non-brokered deposits grew by $703 million and FHLB advances were paid down by $2.4 billion between March 31, 2023 and December 31, 2023.

•Consistent with our strategic objective of improving the profitability of the asset mix, during 2023, our core C&I and CRE loan portfolio sub-segments grew by $719 million, from 56% to 60% of loans, while generally lower-yielding residential loans declined by $692 million, from 36% to 33% of loans.

•The net interest margin for the year ended December 31, 2023 was 2.56% compared to 2.68% for the year ended December 31, 2022, due in large part to an unfavorable shift in the funding mix. After declining

42

BankUnited, Inc. 2024 Proxy Statement

from 2.62% for the first quarter of 2023 to 2.47% for the second quarter, margin expanded to 2.56% for the third quarter and 2.60% for the fourth quarter of 2023.

•Credit remains favorable. The NPA ratio was 0.37%, 0.25% excluding the guaranteed portion of SBA loans(1), at December 31, 2023, well below pre-pandemic levels. The net charge-off ratio for the year ended December 31, 2023 was 0.09%.

•Our capital position is robust. The Company’s and the Bank’s capital ratios continued to exceed all regulatory ‘well-capitalized’ guidelines. Consolidated CET1 capital was 11.4% at December 31, 2023.

•Liquidity is ample. Total same day available liquidity was $13.6 billion and the available liquidity to uninsured, non-collateralized deposits ratio was 152% at December 31, 2023.

•Book value and tangible book value per common share grew to $34.66 and $33.62, respectively, at December 31, 2023, from $32.19 and $31.16, respectively, at December 31, 2022.

•In the first quarter of 2023, the Company increased its quarterly cash dividend by $0.02, to $0.27 per share, an 8% increase from the prior year quarterly cash dividend of $0.25 per share.

•In 2023, BankUnited was listed as number one among America's Top 100 Healthiest Employers by Springbuk HR Technology and was recognized by Newsweek as one of America’s Greatest Workplaces.

(1) The ratio of non-performing assets to total assets excludes the guaranteed portion of portion of SBA loans, which is a non-GAAP financial measure. See section entitled "Non-GAAP Financial Measures."

(2) Tangible book value per share is a non-GAAP financial measure. See the section entitled “Non-GAAP Financial Measures” on page 69 of the Company's Form 10-K for the fiscal year ended December 31, 2023 on our website at https://ir.bankunited.com for a reconciliation of this non-GAAP financial measure to the respective comparable GAAP financial measurement.

(3) There is no Tier 1 leverage ratio component in the definition of a well-capitalized bank holding company.

Compensation Philosophy and Objectives

    BankUnited's executive compensation program is centered on a pay-for-performance philosophy, which aligns executive compensation with shareholder value and determines program design. We believe that our compensation program also discourages inappropriate risk-taking by avoiding undue emphasis on any one metric

45

BankUnited, Inc. 2024 Proxy Statement

or short-term goal, including metrics reflective of appropriate risk management and having a cap on incentive payments.

Best Practices in Executive Compensation

The Company employs a number of practices that reflect our commitment to good compensation governance.

WHAT WE DO	WHAT WE DON'T DO
ü Use an independent compensation consultant to advise on executive compensation matters	r Do not have compensation programs that encourage unnecessary and excessive risk taking
ü Design compensation programs to drive long-term performance	r No income tax or excise tax gross-ups
ü Incorporate an overriding performance condition in our performance metrics	r No reloading, repricing or backdating options
ü Consider peer group data when making executive compensation decisions; many of our performance metrics are measured relative to the peer group and are formulaic in nature	r Do not permit hedging, pledging or short-selling of the Company's stock by executive officers
ü Set multi-year vesting periods for equity awards	r Do not provide excessive severance arrangements
ü Have an equity ownership and retention policy for NEOs	r Do not pay dividends or dividend equivalents on performance share units (PSUs) or restricted share units (RSUs) until vested
ü Have a compensation recovery policy	r Do not provide guaranteed bonuses to our NEOs
ü Regularly engage with shareholders on compensation and governance matters
ü Maintain an independent Compensation Committee
ü Provide a majority of the NEOs' compensation opportunity in the form of incentive awards, aligning compensation with the Company's performance

Consideration of Say-on-Pay Vote Results

    At our most recent annual meeting of shareholders, held on May 16, 2023 the Company conducted an advisory vote to approve its executive compensation for the fiscal year ended December 31, 2022. Shareholders approved the compensation of our NEOs, with 98.6% of the votes present in person or represented by proxy at the meeting and entitled to vote on the matter cast to approve our 2022 executive compensation proposal. The Compensation Committee considers the high level of support for our recent Say on Pay votes - averaging over 91% for the last five years when reviewing our executive compensation program and will continue to consider shareholder feedback and the results of say-on-pay votes when making future compensation decisions.

HOW COMPENSATION DECISIONS ARE MADE

Role of the Compensation Committee

Our Compensation Committee, which is composed entirely of independent directors, is responsible for overseeing the compensation and benefit programs for our NEOs and non-employee directors. Our Compensation Committee meets at least quarterly (four times in person, three times virtually and once by written consent in 2023) to approve amounts paid to our NEOs and non-employee directors and administer our incentive plans,

46

BankUnited, Inc. 2024 Proxy Statement

which includes the determination of performance metrics, target pay levels, grant amounts and vesting terms of awards under such plans. Our Compensation Committee is responsible for determining whether our executive compensation policies are reasonable and appropriate, that compensation practices meet the stated objectives of those policies and effectively serve the best interests of the Company and our shareholders.

Role of Management

    In evaluating compensation, our Compensation Committee receives and considers information on performance and recommendations on pay from our Chief Executive Officer for our other named executives . Our Compensation Committee has discretion to approve, disapprove or modify recommendations made by our Chief Executive Officer. Our Chief Executive Officer is not present during deliberations or voting by our Compensation Committee relating to his own compensation.

Role of our Independent Compensation Consultant

Pursuant to its charter, our Compensation Committee may in its sole discretion, retain or obtain the advice and assistance of a compensation consultant, legal counsel or other adviser. Our Compensation Committee may retain or obtain the advice of an adviser only after taking into consideration factors related to that person’s independence from management, including each of the factors it is required to take into consideration under the Corporate Governance Standards of the New York Stock Exchange, subject to limited exceptions. Our Compensation Committee is responsible for the appointment, compensation, and oversight of any adviser it retains. The Company is obligated to provide appropriate funding for the compensation of any such adviser.

The Compensation Committee has retained Pay Governance as its independent compensation consultant. The compensation consultant assists the Compensation Committee in reviewing the framework of the Company's executive compensation program as well as compensation packages including direct salary, annual incentive and long-term equity incentive programs for Mr. Singh, Mr. Cornish, Ms. Lunak and Mr. Bansal. Pay Governance does not provide any other services to the Company.

Compensation Peer Group

The Compensation Committee selects a compensation peer group in consultation with its independent compensation consultant, considering such factors as similarity in size based on total assets, market capitalization and number of employees, comparability of size and nature of the loan and deposit portfolios, capital levels, similarity in business model and strategy, geographic footprint, whether a company is a key competitor, proxy advisor-defined peers and other qualitative factors. The Company does not seek to set compensation at a specific level relative to the peer group, but may consider compensation levels of peer group executives as one factor in its evaluation of executive compensation levels. The Compensation Committee further benchmarks certain incentive performance metrics against comparative peer group results and may consider compensation governance practices of peers among other factors in its evaluation of the Company's practices.

47

BankUnited, Inc. 2024 Proxy Statement

The peer group was reviewed by the Compensation Committee, in consultation with its independent compensation consultant, with respect to 2023 incentive awards. The 16 members of the 2023 peer group are:

Ameris Bancorp	Prosperity Bancshares, Inc.
Associated Banc-Corp	SouthState Corporation
BOK Financial Corporation	Synovus Financial Corp.
Cadence Bank	Texas Capital Bancshares, Inc.

2023 COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Overriding Performance Condition

If the Company failed to be well-capitalized at December 31, 2023, as defined by the applicable federal banking regulator for purposes of the prompt corrective action provisions of the Federal Deposit Insurance Act, no performance-based awards would be payable or granted to the Chief Executive Officer, Chief Financial Officer, Chief Operating Officer or Chief Investment Officer regardless of the Company having met the established performance criteria.

2023 Capital Position

•Exceeded all requirements to be considered "well capitalized"

•Total risk-based capital of 13.4%

•CET1 risk-based capital of 11.4%

•Tier 1 leverage ratio of 7.9%

Key Components of our Executive Compensation Program

    Our executive compensation program provides a mix of salary, short- and long-term incentives, and benefits that we believe are aligned with our business strategy and are designed to maximize long-term shareholder value.

    

48

BankUnited, Inc. 2024 Proxy Statement

In light of our focus on paying for performance, the Compensation Committee structures compensation packages for the NEOs such that a majority of each officer's target compensation opportunity is delivered through incentive compensation, with a significant portion (and in the case of the CEO, a majority) of the total target incentive compensation opportunity delivered through long-term incentive compensation.

2023 Base Salaries

     The table below presents the 2022 and 2023 base salaries for each of the NEOs. The Compensation Committee reviews salaries annually. The Committee reviewed base salaries in March 2023 and adjusted the salary for Mr. Richards as a result of this review effective March 1, 2023.

NEO	2022 Base Salary	2023 Base Salary
Rajinder P. Singh	$1,050,000	$1,050,000
Leslie N. Lunak	$525,000	$525,000
Thomas M. Cornish	$661,500	$661,500
Rishi Bansal	$472,500	$472,500
Jay D. Richards	$400,000	$425,000

2023 Annual Incentive Awards

Messrs. Singh, Cornish and Bansal and Ms. Lunak

Each year, the Compensation Committee sets the performance criteria that are used to calculate the annual incentive awards for Messrs. Singh, Cornish and Bansal and Ms. Lunak. Mr. Richards does not participate in the AIP designed for Messrs. Singh, Cornish and Bansal and Ms. Lunak due to the importance of objectivity on the part of the Chief Risk Officer in focusing on credit quality and risk management, and the risk that such objectivity could appear to be compromised if the metrics used to determine AIP awards for the other NEOs were used in determining Mr. Richards' awards.

The Compensation Committee considers the Company's: (i) overall strategy, (ii) specific near-term strategic objectives, (iii) opportunities and challenges presented by external factors, such as the banking liquidity crisis of early 2023, (iv) any feedback received from shareholders, (v) best practices among peers, (vi) advice from the Committee's independent compensation consultant, and other factors the Committee considers relevant when evaluating and establishing performance criteria. In 2023, the Compensation Committee structured the AIP program so that 75% of the AIP awards for Messrs. Singh, Cornish, and Bansal and Ms. Lunak in respect of fiscal 2023 would be determined based on three predetermined financial performance metrics and 25% of the AIP award would be determined by the achievement of key strategic objectives established by the Compensation Committee that position the Company for long-term success. The Compensation Committee believes that basing

50

BankUnited, Inc. 2024 Proxy Statement

25% of the AIP award on achievement of key strategic objectives provides the Committee with a mechanism by which its review of the Company's overall performance for the year, including progress toward achievement of strategic priorities and management's response to uncertainty and volatility in the operating environment, can impact incentive payouts.

Performance Metrics - 75%		Strategic Objectives - 25%
Weight	Measurements	Weight	Measurements
25%	Ratio of Non-Interest-Bearing Demand Deposits (“NIDDA”) to Total Deposits	25%	•Successful navigation of the 2023 Banking Crisis •Regulatory standing of the Company •iCARETM initiatives •Other factors arising during the year that the Committee considers relevant in assessing performance
50%	Relative 1-year growth in Tangible Book Valuer Per Share
	Relative Non-Performing Assets Ratio

The table below presents the 2023 AIP Award Opportunity for each of our NEOs:

Performance Level	Payout (% of Target)	Rajinder P. Singh	Leslie N. Lunak	Thomas M. Cornish	Rishi Bansal
< threshold	—%	–	–	–	–
threshold	50%	$787,500	$229,688	$496,125	$236,250
target	100%	$1,575,000	$459,375	$992,250	$472,500
maximum	150%	$2,362,500	$689,063	$1,488,375	$708,750

For the portion of the AIP award based on performance metrics measured relative to the compensation peer group (relative performance component), the payout is based on an average percentile ranking ("APR"). The following table presents the payout grid for these metrics:

APR	Payout (% of Target)
<25%	—%
25%	50%
50%	100%
75%	150%

For the portion of the AIP award based on performance metrics measured relative to values or levels predetermined by the compensation committee (absolute performance component), performance at the threshold level as established by the compensation committee results in a payout equal to 50% of target, performance at the target level results in a payout at 100% of target and performance at the maximum level results in a payout at 150% of target. Performance below the threshold level results in no payout for this component of the AIP.

For all components of the AIP award, performance between threshold and target and between target and maximum is interpolated on a linear basis.

Absolute Performance Component

The Compensation Committee determined that non-interest bearing demand deposits ("NIDDA") as a percentage of total deposits would have a threshold level of 18% below which no payout is earned, a target level

51

BankUnited, Inc. 2024 Proxy Statement

of 22% at which 100% of the target payout is earned, and a maximum performance level of 25% at which a payout of 150% of target is earned. The value from the Company's Form 10-K as of December 31, 2023 would determine performance.

At December 31, 2023, NIDDA as a percentage of total deposits was 25.8% resulting in a maximum payout of 150% of target for this component, representing 25% of the total AIP award.

Peer Relative Performance Component

The Company's performance with respect to one-year growth in tangible book value per share and the NPA ratio relative to the 2023 compensation peer group were each assigned a percentile ranking compared to the defined compensation peer group. Those two performance metrics were weighted equally for the purpose of calculating an APR used in determining the peer relative performance component, representing 50% of the total annual incentive payout. Performance at the 25th percentile is required to earn a threshold payout of 50% of target, 50th percentile (median) performance is required to earn a target payout of 100% and 75th percentile performance is required to earn a maximum payout of 150% of target. No payment related to this component of the annual incentive award is made unless the threshold performance level is achieved.

For the year ended December 31, 2023, the APR for these two metrics was calculated at 40.8% which interpolated on a linear basis between threshold and target, resulted in a payout of 81.5% of target.

Results for 2023 Performance Metrics, which form the basis for 75% of the AIP awards are summarized in the grids below:

Performance Metric	Threshold	Target	Maximum	Actual at Dec. 31, 2023
NIDDA as % of Total Deposits	18%	22%	25%	25.8%

	Growth in Tangible Book Value Per Share(a)	NPA Ratio(b)	APR
BankUnited	9.02%	0.25%
Percentile Ranking	16.40%	65.10%	40.8%

(a)    For purposes of determining growth in tangible book value of the Company or its peers, reported amounts may be adjusted to remove the impact of material, unusual, or non-recurring items at the discretion of the Compensation Committee. These adjustments of necessity require a certain degree of judgment. The amount of such adjustments is not determined by any of the NEOs whose compensation is impacted by the results and is reviewed by the Compensation Committee. As predefined by the Compensation Committee, growth in tangible book value per share excluded the impact of any FDIC Special Assessment for the Company and the peer group. No other adjustments were made.

(b)    As predefined by the Compensation Committee, the ratio of non-performing assets to total assets excluded the guaranteed portion of portion of SBA loans, which is a non-GAAP financial measure. See section entitled "Non-GAAP Financial Measures."

Strategic Objectives Component

The strategic objectives component of the AIP award is designed to provide the Compensation Committee the ability to impact the amount of annual incentive payments based on a complete review of the Company's overall performance including, in addition to predetermined financial performance metrics, progress toward accomplishment of key strategic priorities and management's response to uncertainty and volatility in the operating environment.

The key strategic priorities identified by the Compensation Committee for fiscal year 2023 and the most important factors considered by the Committee in evaluating each are described below.

Mr. Richards

    In 2023, Mr. Richards was eligible to receive a cash incentive award determined in accordance with the Company's Policy on Incentive Compensation Arrangements, which provides that incentive amounts are to be based on the past, present and expected future contributions of an employee or group of employees to the overall success, safety and soundness of the organization. Factors considered by the Compensation Committee in evaluating those contributions include, among other things, overall individual performance, overall organizational performance, individual contribution to organizational performance, business segment or departmental performance, successful completion of projects or initiatives and level of individual responsibilities. The Company's Policy on Incentive Compensation Arrangements is designed to balance risk and financial, operational and strategic results in a manner that does not encourage employees to expose the Company to imprudent risks.

In evaluating Mr. Richards' performance for 2023, the Compensation Committee considered Mr. Richards' contribution to organizational performance as aligned with his role as Chief Risk Officer. Criteria specifically considered by the Committee included Mr. Richards' support in further development of a program to cultivate a risk awareness culture with employees and implement an enterprise-wide Risk and Control Self Assessment framework, enhancements to the Company's overall risk assessment framework; maintenance of solid regulatory relations and serving as the primary point of contact with banking regulators; maintaining appropriate portfolio concentrations and reporting on portfolio performance; maintaining acceptable asset quality metrics; and providing input, oversight and effective challenge to the ACL process. Based on consideration of the foregoing factors and others deemed relevant by the Compensation Committee, on February 21, 2024, the Committee approved an annual cash incentive award for Mr. Richards in the amount of $350,000. Mr. Richards'annual cash incentive award was reduced from the 2022 level, in recognition of lower earnings for the Company in 2023.

In 2023, Messrs. Singh, Cornish and Bansal and Ms. Lunak were eligible to receive an annual grant of PSUs. The following chart summarizes the performance metrics that will determine the number of PSUs that ultimately vest:

Relative Performance Metrics - 75%		Absolute Performance Metrics - 25%
Weight	Measurements	Weight	Measurements
75%	Relative improvement in the ratio of Uninsured, Non-Collateralized Deposits to Total Deposits	12.5%	Total Loan Commitments + Total Deposits in new geographies
	Relative 3-year Total Shareholder Return (TSR)	12.5%	Retention rate of high performing employees at the officer level of Senior Vice President and above

•75% of the PSU award will be determined based on the achievement of two equally-weighted performance metrics determined by the Compensation Committee and measured relative to the 2023 compensation peer group. These performance metrics are:

•Relative improvement in the ratio of uninsured, non-collateralized deposits to total deposits based on values reported in the December 31st call report for the years ended December 31, 2022 and December 31, 2025, measured against the compensation peer group

•Relative 3-year total shareholder return ("TSR") measured against banks in the KBW Regional Bank Index at both the beginning and end of the performance period. Banks included in the index at the beginning of the measurement period that declare bankruptcy or insolvency or are closed, transferred, liquidated or put into receivership under a regulatory action will be graded at negative 100% TSR.

•25% of the PSU award will be determined based on the achievement of two performance metrics determined by the Compensation Committee that measure achievement of key strategic milestones. Each of these metrics will determine 12.5% of the total PSU award. Threshold, target and maximum levels of performance for these two performance metrics were set by the Compensation Committee and are not measured relative to the peer group:

•Execution on expansion into new geographies measured as the absolute value of total loan commitments + total deposits in new geographies (including Atlanta, Dallas and other geographies, if any, identified at a future date within the performance measurement period) at the end of the three-year performance measurement period

•Average annual turnover rate of high performing (defined as receiving exceeds expectations performance evaluations) employees at the officer level of Senior Vice President and above.

The metrics described above are those that the Compensation Committee believe best align the compensation of our NEOs with the interests of our shareholders over the three-year performance measurement period and further provides balance between strong relative performance and the achievement of absolute performance goals. Relative three-year total shareholder directly aligns the compensation of our NEOs with financial returns earned by our shareholders over the performance measurement period. Relative improvement in the uninsured, non-collateralized deposits to total deposits ratio measures achievement with respect to a key

55

BankUnited, Inc. 2024 Proxy Statement

liquidity risk measure that has been elevated to prominence within the bank investor community following the 2023 banking liquidity crisis. Execution on expansion into new geographies and retention of key high performing employees are strategic objectives that the Compensation Committee and Board of Directors believe are important to improving future returns.

At the end of the performance period, the Company's performance with respect to each of the two equally-weighted performance metrics that are measured relative to the compensation peer group, which determine 75% of the total PSU award, will be assigned a percentile ranking. The number of PSUs earned with respect to this component of the total award at the end of the performance period will be determined based on the APR. The performance grid for this component of the PSU award is presented below:

APR	Payout (% of Target)
<25%	—%
25%	50%
50%	100%
75%	150%

The performance grid for this component of PSU awards is structured such that a target payout requires performance at the 50th percentile (median). Performance at less than a threshold level of the 25th percentile results in a payout of zero related to this component. Performance at the 50th percentile results in a payout at 100% of target. Performance at or above the 75th percentile results in the maximum payout of 150% of target related to this component.

At the end of the performance period, the Company's performance with respect to the absolute performance metrics, which comprise 25% of the total PSU award, will be determined by comparison to threshold, target and maximum levels predetermined by the Compensation Committee. Performance at the threshold level will result in a payout of 50% of target, performance at the target level will result in a payout at 100% of target and performance at the maximum level will result in a payout at 150% of target for these components of the PSU award. The performance levels for these metrics are presented below:

Performance Level	Payout (% of Target)	Key Employees Turnover Metric (12.5% Weight)	Geographic Expansion Metric (sum of loan commitments and deposits) (12.5% Weight)
Threshold	50%	9.0%	$1.5 billion
Target	100%	6.0%	$2 billion
Max	150%	3.5%	$2.5 billion

For all performance metrics, performance between the threshold and target levels and between the target and maximum performance levels will be interpolated on a linear basis. Awards are capped at 150% of each NEO's target.

The PSU award was denominated in a target number of shares at the beginning of the performance period based on the target value of the PSU award and the fair market value of the Company's common stock at the grant date. The actual number of shares earned will be determined at the end of the three-year performance measurement period based on actual performance.

Mr. Richards

For similar reasons as those discussed above with respect to the AIP, Mr. Richards did not participate in the LTIP that was designed for Messrs. Singh, Cornish and Bansal and Ms. Lunak, but was eligible to receive a restricted share award in accordance with the Company's Policy on Incentive Compensation Arrangements, the amount of which was determined by the Committee based on criteria considered relevant by the Committee, which included:

•Executing proper governance and oversight of Enterprise Risk Management and Credit Risk Management;

•Maintaining a sound enterprise risk management and monitoring framework commensurate with the size and complexity of the organization;

•Ensuring maintenance of a robust credit risk rating system and processes; and

•Promoting a balanced risk-taking culture.

On February 21, 2024, the Compensation Committee evaluated the performance of Mr. Richards for his performance in the 2023 fiscal year and overall contributions to the Company and effective March 1, 2024 approved a restricted share award of 13,000 shares to Mr. Richards, which are scheduled to vest in equal installments on March 1, 2025, 2026, 2027 and 2028, subject to his continued service. In accordance with the SEC rules, we expect to report this grant in the Summary Compensation Table and the 2024 Grants of Plan-Based Awards table below in our 2025 proxy statement.

On February 23, 2023, the Compensation Committee evaluated the performance of Mr. Richards for his performance in the 2022 fiscal year and overall contributions to the Company and granted a restricted share award of 13,000 shares to Mr. Richards. In accordance with the SEC rules, we reported this grant in the Summary Compensation Table and the 2023 Grants of Plan-Based Awards Table below.

PSUs Granted in March 2020

    As previously disclosed in our 2021 proxy statement, Messrs. Singh, Cornish and Bansal and Ms. Lunak were granted PSUs in March 2020. The performance period for the PSUs granted in March 2020 commenced on January 1, 2020 and ended on December 31, 2023.

Performance was based on the achievement relative to selected peers of three equally-weighted performance metrics, which were chosen by the Compensation Committee: (i) relative growth in diluted earnings per share, (ii) relative average annual net charge-off ratio and (iii) relative 4-year total shareholder return. Relative growth in earnings per share and relative average annual net charge-off ratio were measured against the 2020

57

BankUnited, Inc. 2024 Proxy Statement

Compensation Peer Group and relative 4-year total shareholder return was measured against the banks in the KBW Nasdaq Regional Bank Index at both the beginning and the end of the performance period, except for banks that declared bankruptcy or insolvency or were closed, transferred, liquidated or put into receivership under a regulatory action during the performance period; at the direction of the Compensation Committee, these banks were included at a TSR of negative 100%.

The Compensation Committee reviewed the Company's performance with respect to each of the performance metrics in March 2024 and determined the percentile ranking for each metric relative to the compensation peer group. The amount awarded was determined based on the APR in accordance with the following grid. As depicted in the grid, performance at the 25th percentile is required to earn a threshold payout of 50% of target, 50th percentile (median) performance is required to earn a target payout of 100% and 75th percentile performance is required to earn a maximum payout of 150% of target. No payment is made unless the threshold performance level is achieved. Performance between threshold and target and target and maximum performance is interpolated on a linear basis.

Rishi Bansal	$162,500	7,112	$325,000	14,224	$487,500	21,335

The following chart shows the performance results for the PSUs granted in 2020.

	Relative Growth in Earnings per Share	Relative Net Charge-off Ratio	Relative 4-year Total Shareholder Return	APR
BankUnited	32.52%	0.22%	1.13%
Percentile Ranking	33.80%	35.30%	26.20%	31.77%

For the year ended December 31, 2023 at the calculated APR of 31.77%, interpolated on a linear basis,the shares awarded were 35,012 for Mr. Singh, 15,440 for Mr. Cornish, 8,754 for Ms. Lunak and 9,104 for Mr. Bansal. The below target level performance for the 2020 - 2023 LTIP PSUs can be attributed to the establishment of rigorous goals impacted by the challenging economic environment and 2023 banking crisis.

OTHER ELEMENTS OF COMPENSATION

Retirement Programs    

    All of the Company's full-time employees (including the Company's NEOs) are eligible to participate in a 401(k) plan. In addition, certain of the Company's employees, including the NEOs, are eligible to participate in

58

BankUnited, Inc. 2024 Proxy Statement

our Nonqualified Deferred Compensation Plan, the terms of which are described in additional detail below under "Nonqualified Deferred Compensation." The Company has no defined benefit pension plans.

Welfare Programs

    The Company offers a variety of health and other welfare benefit programs to all employees, including medical, dental, vision, life insurance and disability insurance. The Company's NEOs are generally eligible to participate in these employee benefit plans on the same basis as the rest of the Company's employees. In addition, pursuant to Mr. Singh's employment agreement, the Company pays all premiums on and otherwise maintains in good standing a second to die split-dollar life insurance arrangement providing for a death benefit of $15 million.

No Excise Tax Gross-Ups; Perquisites

    The Company does not provide excise tax gross-ups to its employees. Mr. Singh has non-exclusive access to a Company provided automobile and driver primarily for business purposes, with access for personal use depending on availability. This limited transportation perquisite is similar to that offered by companies with which the Company competes for talent and enables employees to better focus on their duties to the Company. In addition, when traveling on Company business, the CEO is occasionally permitted to bring family members on the Company aircraft, which does not result in incremental cost to the Company. The imputed value of this perquisite is included in "all other compensation" in the Summary Compensation Table below.

Limited Severance Arrangements

    In order to promote the retention of our executive leadership team, particularly in the event of a potentially disruptive corporate transaction, the Company provides customary but limited severance arrangements to its NEOs. In addition, the CEO is party to an employment agreement with the Company. The terms of these arrangements are described below under "Potential Payments Upon Termination or Change-in-Control."

OTHER CONSIDERATIONS

Equity Ownership Requirement

We believe that requiring members of our executive management to invest and maintain ownership in our Company better aligns their interests with the interests of our shareholders. The Company's Executive Ownership Policy provides that so long as the executive is employed and a NEO, the executive will not sell equity other than for purposes of tax withholding due upon the settlement of an equity award or to pay the exercise price due upon the exercise of an option if after giving effect to such sale, his or her respective retained equity (including vested and unvested shares) has a value that is less than the stipulated multiple of his or her salary.

The multiples of salary currently stipulated in the policy are:

Named Executive Officer	Minimum Equity Ownership
Chief Executive Officer	6 times base salary
All Other Named Executive Officers	3 times base salary

The NEOs have three years from the date they were appointed as a NEO to meet their target ownership level. The stock ownership requirement may be satisfied by:

•Vested and unvested common stock

•Vested and unvested restricted share units

•Common stock held after the exercise of stock options

(1) Based on the $28.00 closing price of our stock price on March 28, 2024.

Compensation Recovery Policy

In 2023, the Company updated its Compensation Recovery Policy ("the Policy") to comply with new SEC rules and NYSE listing standards with respect to recovery of erroneously awarded incentive-based compensation received by covered executives in the event of a required accounting restatement. The Policy, which is administered by our Compensation Committee, provides that if we are required to prepare an accounting restatement of our financial statements due to material noncompliance with any financial reporting requirement under the securities laws, any incentive compensation granted, earned or vested during the applicable lookback period based on the attainment of a financial reporting measure that exceeds the amount that would have been paid after giving effect to the restatement must be recouped from the covered executives. Any right of recovery under this Policy is in addition to, and not in lieu of, any other remedies or rights of recovery, recoupment, forfeiture or offset that may be available to the Company, however, that there shall be no duplication of recovery of the same compensation.

Anti-Hedging and Anti-Pledging of Company Securities

    Pursuant to our Insider Trading Policy, our directors, executive officers, and other employees and their related parties, which includes spouses, minor children, and other family members who reside in the same household and any other entities in which such persons exercise or share control (“Covered Persons”) are prohibited from engaging in short sales of the Company's securities, pledging the Company’s securities as collateral for a loan or holding the Company’s securities in a margin account.

    Directors and executive officers of the Company are prohibited from engaging in hedging transactions with respect to Company securities such as (but not limited to) zero-cost collars, equity swaps, and forward sale contracts. Any other Covered Person is prohibited from engaging in any such hedging transactions while in possession of material non-public information regarding the Company.

Tax Implications

    Section 162(m) of the Internal Revenue Code generally disallows a federal income tax deduction to public companies for compensation greater than $1 million paid in any tax year to covered executive officers. Despite this limitation on the tax deductibility of executive compensation, the Compensation Committee considers it important to design and implement compensation programs that it believes are competitive and in the best interests of the Company and its shareholders.

Compensation Risk Assessment

At least annually, our Compensation Committee assesses the compensation policies and practices applicable to our employees, including our executive officers, and considers whether such policies and practices create risks that are reasonably likely to have a material adverse effect on the Company. Additionally, our Enterprise Risk Management group periodically performs an independent risk assessment of all of the Company's

60

BankUnited, Inc. 2024 Proxy Statement

incentive compensation arrangements, including those applicable to our NEOs. The most recent such risk assessment was completed in 2020.

We believe our compensation programs strike the appropriate balance between the short-term and long-term performance of the Company. We consider the potential risks in our business when designing and administering our compensation programs, and we believe our balanced approach to performance measurement and compensation decisions mitigates the risk that employees, including our executive officers, will be encouraged to undertake excessive or inappropriate risk. The Company's compensation program also is subject to internal controls and to audit by our internal audit function, and we rely on principles of sound governance and good business judgment in administering our compensation programs.

Based on its assessment in 2023, our Compensation Committee has determined, in its reasonable business judgment, that the Company's compensation policies and practices as generally applicable to its executive officers and employees do not create risks that are reasonably likely to have a material adverse effect on the Company.

1.Mr. Richards base salary was increased from $400,000 to $425,000 effective March 1, 2023.

2.For Mr. Richards, who in accordance with the Company's Policy on Incentive Compensation Arrangements does not participate in the AIP program that is designed for our other NEOs, the amount reported for 2023 represents an incentive bonus earned for performance in 2023 and paid during the first quarter of 2024.

3.Amounts shown do not reflect the compensation actually realized in 2023 by the NEOs. Instead, amounts represent the aggregate grant date fair value of RSUs, PSUs and RSAs granted to the NEOs during 2023 calculated in accordance with FASB ASC Topic 718. For additional information on the assumptions used in determining fair value for share-based compensation, refer to Notes 1 and 12 to the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

4.On March 24, 2023, the Compensation Committee awarded Mr. Singh 70,106 RSUs and 70,106 PSUs, Mr. Cornish 30,917 RSUs and 30,917 PSUs, Ms. Lunak 17,527 RSUs and 17,527 PSUs and Mr. Bansal 18,228 RSUs and 18,228 PSUs. For PSUs, the amount included is based on the probable outcome of performance conditions, which is equal to the target amount. Assuming satisfaction of performance conditions at the maximum level, the PSUs granted to (w) Mr. Singh would have had a grant date fair value of $2,264,073 (as opposed to the target grant date fair value of $1,509,382 reported above); (x) Mr. Cornish would have had a grant date fair value of $998,454 (as opposed to the target grant date fair value of $665,643 reported above); (y) Ms. Lunak would have had a grant date fair value of $566,024 (as opposed to the target grant date of $377,356 reported above); and (z) Mr. Bansal would have had a grant date fair value of $588,673 (as opposed to the target grant date of $392,449 reported above).

5.Other than RSUs and PSUs, we typically grant restricted share awards to Mr. Richards, who in accordance with the Company's Policy on Incentive Compensation Arrangements does not participate in the LTIP program that is designed for our other NEOs, in the first quarter of each year as part of total year-end compensation awarded for prior year performance. As a result, the amounts for those stock awards generally appear in the Summary Compensation Table for the year after the performance year upon which they were based. On March 1, 2023, Mr. Richards was awarded 13,000 restricted shares for his performance in the 2022 fiscal year and overall contributions to the Company. In accordance with the SEC rules, the value of the restricted shares awarded to Mr. Richards in March 2024 for his performance in the 2023 fiscal year and overall contributions to the Company is not included here and will be reported in the Company's proxy statement for the 2025 annual meeting of stockholders.

6.For each Messrs. Singh, Cornish, Bansal and Ms. Lunak the amounts reported reflect a performance-based cash incentive award earned for performance in 2023 and paid in the first quarter of 2024.

1.Mr. Richards does not participate in the Company's Nonqualified Deferred Compensation Plan.

2.The full amount of the contribution for Messrs. Singh and Bansal and Ms. Lunak to the Nonqualified Deferred Compensation Plan is reflected as compensation earned as part of each executive's "Salary", and/or "Bonus" or "Non-Equity Incentive Plan Compensation" in 2023 in the "Summary Compensation Table for 2023."

3.Amounts reflect our contributions, if any, to the Nonqualified Deferred Compensation Plan for the applicable NEO. These amounts are also reported in the "All Other Compensation" column of the "Summary Compensation Table for 2023."

4.These amounts include amounts previously reported in the Summary Compensation Table as "Salary," "Bonus," "Non-Equity Incentive Plan Compensation" or "All Other Compensation" for years prior to 2023, in the following aggregate amounts: $1,018,124 for Mr. Singh, $397,500 for Ms. Lunak and $516,409 for Mr. Bansal.

Our Nonqualified Deferred Compensation Plan allows each NEO to defer up to 100% of salary and cash bonus or incentives. Mr. Singh is eligible to receive company matching contributions under the plan. For the 2023 plan year, we contributed an amount equal to 100% of the first 1% plus 70% of the next 5% of eligible compensation that Mr. Singh elected to defer under the plan. Amounts deferred by a NEO are vested at all times and amounts that we contribute on the executive's behalf will become vested upon the earlier to occur of a change in control (as defined in the plan), the executive's death, disability, attainment of age 65 or completion of two years of service. The Company credits each participant's account with income based on either an annual interest

rate determined by the Company's Compensation Committee or returns of selected investment portfolios, as elected by the participant. The annual interest rate has varied from year but has ranged from a low of 5.00% in 2021 to a high of 7.50% in 2023. Amounts deferred under our Nonqualified Deferred Compensation Plan are distributed upon a date or dates specified by the executive, which may be no earlier than January 1 of the third plan year following the plan year in which the compensation would have otherwise been paid to the executive, or upon the earliest to occur of the executive's separation from service, disability or a change in control.

Potential Payments Upon Termination or Change-in-Control

The employment arrangements with our NEOs provide for certain severance payments and benefits, to the extent applicable, in the event of a termination of employment as described below:

Employment Agreement with Mr. Singh

Mr. Singh is the only executive subject to an employment agreement. Mr. Singh has been a party to various employment agreements with us since July 2009. Mr. Singh's current employment agreement (the "Agreement") provides for a term of three years commencing on January 1, 2023 (the "Employment Term") and reflects his current base salary of $1,050,000.

Commencing on January 1, 2026 and on January 1 of each year thereafter, the Employment Term will automatically renew for additional one-year periods on the same terms and conditions contained in the Agreement unless at least 90 days prior to any such anniversary date either party shall notify the other in writing that it does not wish to extend the Employment Term beyond the then applicable expiration date. In the event of the public announcement of a transaction or other event that would constitute a change in control, as defined, (a "Public Announcement") during the Employment Term, the Employment Term would be automatically extended as necessary such that it expires on the later of the last day of the then-current Employment Term and the second anniversary of the change in control.

The employment agreement with Mr. Singh provides that, in the event of termination of his employment by the Company without Cause or by him for Good Reason (as defined in the Agreement) during the Employment Term, Mr. Singh would be entitled to receive, subject to an execution of a release of claims against the Company, (i) payment of an amount equal to two times the sum of his base salary and target annual incentive opportunity (or three times such sum if termination occurs on or following a change in control); (ii) payment of his prorated annual incentive award based on actual performance for the year of termination (or a prorated annual incentive award based on target performance if termination occurs on or following a change in control); (iii) full vesting of his RSU awards (and any other time-based equity awards); (iv) vesting of his PSU awards based on actual achievement for the performance criteria (or, if the termination occurs following a Public Announcement, the PSU awards will convert into a time-based RSU award (with the number of units determined based on the award agreement) that vests on the later of the change in control and the date of termination); (v) continued coverage under the Company’s group health plans at the Company’s expense for up to 24 months following termination; and (vi) continuation of Mr. Singh's split-dollar life insurance arrangement.

In addition, the employment agreement provides that, in the event of Mr. Singh's termination of employment during the Employment Term, due to his death or Disability (as defined in the Agreement), Mr. Singh would be entitled to receive the benefits described in (iii)-(vi) above. In the event Mr. Singh's employment with the Company terminates for any reason following expiration of the Employment Term he would be entitled to receive the benefits described in (iii), (iv) and (vi) above.

Upon a change in control, the PSU awards granted to Mr. Singh under the Agreement would automatically convert to time-based RSUs (“Converted RSUs”) that vest at the completion of the performance

67

BankUnited, Inc. 2024 Proxy Statement

period, subject to his continued employment with the Company through the vesting date. In the event of Mr. Singh’s termination of employment due to death or Disability, without Cause by the Company, for Good Reason by Mr. Singh or for any reason following the expiration of such employment agreement, prior to a Public Announcement, any unvested portions of the PSU awards would vest based on actual achievement of the performance criteria. If any such termination occurs on or following a Public Announcement and contingent on the consummation of the change in control, the Converted RSUs would fully vest on the later to occur of (i) the date of such change in control and (ii) the termination date.

Mr. Singh's employment agreement does not require the Company to reimburse him for the amount of any golden parachute excise tax imposed under Section 4999 of the Internal Revenue Code. Instead, if the payments to be received by Mr. Singh under the employment agreement would result in the imposition of the golden parachute excise tax, the amount payable would be paid in full or reduced to such lesser amounts that would result in no portion of the payments being subject to the golden parachute excise tax, whichever would result in Mr. Singh's receipt of the greatest amount under his employment agreement on an after-tax basis.

Mr. Singh is subject to confidentiality and non-disparagement obligations under his employment agreement as well as non-competition and non-solicitation covenants for a period of 18 months following a termination of employment during the Employment Term by the Company for Cause or following Mr. Singh's voluntary resignation without Good Reason.

The employment agreement is subject to regulatory laws to the extent applicable.

Change in Control Agreement with Ms. Lunak and Mr. Bansal

Ms. Lunak and Mr. Bansal have change in control agreements pursuant to which, if the executive's employment is terminated by the Company without Cause (as defined in the change in control agreement), or by the executive due to a reduction in base salary, each within six months following a change in control of the Company, the executive would be entitled to a payment in the amount equal to one year of his or her base salary, payable on the date that is six months following the change in control. The agreement further provides for payment, on the date that is six months following completion of the change in control, of a lump sum retention bonus equal to one year of base salary (as in effect immediately prior to the change in control), subject to his or her continued employment with BankUnited and any successor to BankUnited through such date.

Equity Awards

All equity awards (other than the equity awards described under "Employment Agreement with Mr. Singh") that are assumed in connection with, or otherwise continued following, a change in control are not subject to vesting upon a change in control, but are subject to accelerated vesting in the event of a termination of employment without cause or for good reason within 24 months following the change in control.

BankUnited, Inc. 2024 Proxy Statement

The following table provides information concerning the estimated payments and benefits that would be provided in the circumstances described above for each of the NEOs, which were estimated assuming that the triggering event took place on the last business day of the fiscal year (December 29, 2023) and calculated using the closing price per share of our common stock on such date ($32.43), and also assumes a cash-out of equity awards in connection with a change in control.

CEO PAY RATIO

    As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of our CEO. The pay ratio included in this information is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. Given the different methodologies that companies may use to determine their CEO pay ratio, the ratio reported below may not be comparable to the ratios reported by other companies.

We are using the same median employee for our 2023 pay ratio calculation as we used for the 2021 and 2022 calculations. We have not had a significant acquisition, divestiture or reduction in our workforce and the Company's compensation practices have not changed during 2023 in a way that would be expected to significantly impact the pay ratio or median employee. Further, the designated median employee's title, job responsibilities and circumstances have remained similar throughout 2023. As disclosed in our 2021 proxy statement, to determine the median employee and the CEO pay ratio for 2021, we took the following steps:

•We determined that, as of December 31, 2021 our employee population consisted of approximately 1,465 full- and part-time employees, including two temporary employees, all of whom were located in the United States. We have no seasonal employees.

•To identify the “median employee” from our employee population, we compared the amount of gross pay of our employees (excluding our CEO) as reflected in our payroll records as reported to the Internal Revenue Service on Form W-2 for 2021. In making this determination, we annualized the compensation of approximately 242 full-time employees and part-time employees who were hired in 2021 but did not work for us for the entire fiscal year.

•Once we identified our median employee, we combined all of the elements of such employee's compensation for 2021 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K.

•With respect to the annual total compensation of our CEO, we used the amount reported in the "Total" column of our 2021 Summary Compensation Table included in the 2022 Proxy Statement.

    For 2023, our last completed fiscal year:

•based on 2023 compensation for the "median employee" identified in 2021 as described above, we determined the median of the annual total compensation of all employees of our company (other than our CEO) was $100,141 and

•the 2023 annual total compensation of our CEO, as reported in the "Total" column of the Summary Compensation Table included elsewhere in this Proxy Statement was $5,962,451.

Based on this information, for 2023 the ratio of the annual total compensation of Mr. Singh, our Chairman, President and Chief Executive Officer, to the median of the annual total compensation of all employees was 59.5 to 1.

PAY VERSUS PERFORMANCE

As required by Section 953(a) of the Dodd-Frank Act, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid to our principal executive officer ("PEO"), Rajinder P. Singh and non-PEO NEOs (as a group) and certain Company financial performance metrics. For further information concerning our pay-for-performance philosophy and how we align executive compensation with Company financial performance, please refer to the Compensation Discussion and Analysis above.

The following table reports the compensation of our PEO and the average compensation of our non-PEO NEOs as reported in the Summary Compensation Table for the past four fiscal years, as well as their "Compensation Actually Paid" (or "CAP") as calculated pursuant to SEC rules, and certain performance measures required by the rules.

1.The PEO for each year reported was Rajinder P. Singh.

2.The non-PEO NEOs for each year reported were Thomas M. Cornish, Leslie N. Lunak, Rishi Bansal and Jay D. Richards.

3.Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company's stock price at the end and the beginning of the measurement period by the Company's stock price at the beginning of the measurement period. The beginning of the measurement period for each year in the table is December 31, 2019. Historical stock performance is not necessarily indicative of future stock performance.

4.The peer group used for comparison is the KBW Nasdaq Regional Bank Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. Historical stock performance is not necessarily indicative of future stock performance.

5.The ratio of NIDDA to total deposits was determined to be our Company-Selected Measure for 2023. This metric is a performance measure for our 2023 AIP awards and is important to improving the long-term return profile of the Company.

6.The amounts shown for Compensation Actually Paid have been calculated in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually earned, realized, or received by the Company's NEOs. These amounts reflect the amounts set forth in the "Total" column in the Summary Compensation Table with certain adjustments as shown in the table below. Equity fair values are calculated in accordance with FASB ASC Topic 718 and the valuation assumptions used to calculate equity fair values did not materially differ from those disclosed at the time of grant.

Discussion of Performance Measures

Relationship Between PEO and Average Non-PEO NEOs Compensation Actually Paid and the Ratio of NIDDA/Total Deposits

The ratio of NIDDA/Total Deposits, the company selected measure included in the Pay Versus Performance Table, directly impacted compensation actually paid as it was a performance measure used in determining the amount of AIP awards for 2023. While the ratio of NIDDA/Total Deposits declined from 12/31/21 to 12/31/23, this decline was expected as it was consistent with industry trends, the interest rate environment, and restrictive monetary policy. Comparatively, the Company's ratio of NIDDA/Total Deposits declined by 4.7% from 12/31/21 to 12/31/23 while this ratio for the population of banks with between $20 billion and $50 billion in total assets declined by an average of 7.1%. Over the period 12/31/19 (the start of the periods presented in the Pay Versus Performance Table) to 12/31/23, the Company's ratio of NIDDA/Total Deposits improved by 8.1% compared to average improvement of 0.4% for the population of banks with between $20 billion and $50 billion of total assets. The level of NIDDA impacts the Company's long-term earnings performance because it directly impacts the cost of funds and the net interest margin, which in turn directly impact net income and earnings per share. This measure is also important because it is closely aligned with the Company's currently most significant strategic priority, growing non-interest bearing deposits.

Relationship Between Company TSR and KBW Regional Index TSR

The following chart compares our cumulative TSR over the four most recently completed fiscal years to that of the KBW Nasdaq Regional Banking Index over the same period.

The chart above illustrates that while the Company's stock outperformed the index for approximately the first 2 1/2 years of the four-year period presented and underperformed the index over the final 1 1/2 years, on a cumulative basis, the Company's stock has performed consistently with the KBW Regional Bank Index over the periods presented.

BankUnited, Inc. 2024 Proxy Statement

The two preceding charts evidence volatility over the most recent two fiscal years presented in Compensation Actually Paid to our NEOs and in the relationship between Compensation Actually Paid and both company TSR and net income. The following factors were the most significant contributors to this volatility:

•The most significant contributing factor was volatility in the Company's share price. At the date of grant for LTIP awards granted in 2023, the closing price of the Company's common stock was $22.46 while at December 31, 2023 (the most recent measurement date reflected), the closing price of the Company's common stock was $32.43.

•In 2022, Compensation Actually Paid was reduced by the forfeiture of PSUs granted in 2019; these PSUs did not vest and were forfeited because the related performance conditions were not met.

•A third but less significant factor was an increase in the total AIP award for 2023 as compared to 2022, reflecting (i) management's success in defending the non-interest bearing deposit base as discussed above under the heading "Relationship Between PEO and Average Non-PEO NEOs Compensation Actually Paid and the Ratio of NIDDA/Total Deposits" and (ii) the Compensation Committee's consideration of management's successful response to and navigation of the 2023 banking liquidity crisis.

Performance measures the Company considered most important to the determination of compensation actually paid for 2023 include (the measures in this list are not ranked):

■Ratio of NIDDA/Total Deposits

■Non-performing Assets Ratio

■Total Shareholder Return (TSR)

■Management's successful response to and navigation of the 2023 banking liquidity crisis

PROPOSAL NO. 3

ADVISORY VOTE TO APPROVE THE COMPENSATION OF THE NAMED EXECUTIVE OFFICERS ("SAY-ON-PAY")

    As required by Section 14A of the Securities Exchange Act, the Board of Directors is providing our shareholders the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement in accordance with the compensation disclosure rules of the SEC. This vote is referred to as a "Say-on-Pay" vote, which we hold annually.

    As described in more detail under the heading "Compensation Discussion and Analysis," we believe that our executive compensation programs appropriately motivate and retain our executives while effectively aligning the interests of our named executive officers with those of our shareholders. We target total compensation for our NEOs at market and peer group competitive levels, while delivering pay which is linked to company performance over time.

    The vote on this resolution is not intended to address any specific element of compensation; rather, the vote relates to the compensation of our named executive officers generally, as described in this Proxy Statement in accordance with the compensation disclosure rules of the SEC. Because the vote is advisory, it will not be binding upon our Board of Directors or Compensation Committee and we will not be required to take any action as a result of the outcome of the vote. However, our Board of Directors and Compensation Committee value the opinions of our shareholders and will take the results of the vote into consideration when making compensation decisions.

    For the reasons set forth above, and others described elsewhere in this Proxy Statement, the Board of Directors recommends approval of the following non-binding resolution:

"RESOLVED, that the shareholders hereby APPROVE, on an advisory basis, the compensation paid to the Company's named executive officers, as disclosed pursuant to the compensation disclosure rules of the SEC in the Company's Proxy Statement for the 2024 Annual Meeting of shareholders pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis section, the compensation tables and any related material disclosed in this Proxy Statement."

OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" THE RESOLUTION APPROVING THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS ON AN ADVISORY, NON-BINDING BASIS, AS DISCLOSED IN THIS PROXY STATEMENT PURSUANT TO ITEM 402 OF REGULATION S-K, INCLUDING THE COMPENSATION DISCUSSION AND ANALYSIS, COMPENSATION TABLES AND RELATED MATERIAL DISCLOSED IN THIS PROXY STATEMENT.

PROPOSAL NO.4

ADVISORY VOTE TO APPROVE THE FREQUENCY OF THE SHAREHOLDER VOTE TO

APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS IN THE FUTURE

Pursuant to Section 14A of the Securities Exchange Act, we are asking shareholders to vote on whether

future advisory votes on executive compensation of the nature reflected in Proposal 3 on "Say-on-Pay" above

should occur every year, every two years, or every three years.

Our Board believes that continuing to conduct an advisory "Say-on-Pay" vote annually is the most appropriate policy and in the best interest of the Company's shareholders. This gives shareholders the opportunity to provide more regular feedback on our executive compensation program based on the most recent information presented in our proxy statement and enables the Compensation Committee and the Board of Directors to stay better informed of shareholder concerns.

The Company, the Compensation Committee and the Board of Directors has determined that holding an

advisory vote on executive compensation every year is appropriate and in the best interests of the Company's

shareholders. The Company further recommends that our shareholders cast non-binding advisory votes for a "Say on-Pay" proposal on executive compensation brought before our shareholders each year.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS VOTE "EVERY

YEAR" ON THE FREQUENCY OF THE SHAREHOLDER VOTE TO APPROVE THE

COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS IN THE FUTURE.

In order to submit shareholder proposals for the 2025 annual meeting of shareholders for inclusion in the Company's Proxy Statement pursuant to Rule 14a-8 promulgated under Section14(a) of the Exchange Act materials must have been received by the Corporate Secretary at the Company's principal office in Miami Lakes, Florida, no later than December 5, 2024.

The proposals must comply with all of the requirements of SEC Rule 14a-8. Proposals should be addressed to: Corporate Secretary, BankUnited, Inc., 14817 Oak Lane, Miami Lakes, FL 33016. As the rules of the SEC make clear, simply submitting a proposal does not guarantee its inclusion.

The Company's Amended and Restated By-Laws also establish an advance notice procedure with regard to director nominations and shareholder proposals that are not submitted for inclusion in the Proxy Statement, but that a shareholder instead wishes to present directly at an annual meeting. To be properly brought before the 2025 annual meeting of shareholders, a notice of the nomination or the matter the shareholder wishes to present at the meeting must be delivered to the Corporate Secretary at the Company's principal office in Miami Lakes, Florida (see above), not less than 90 or more than 120 days prior to the first anniversary of the date of this year's Annual Meeting. As a result, any notice given by or on behalf of a shareholder pursuant to these provisions of the Company's Amended and Restated By-Laws (and not pursuant to Exchange Act Rule 14a-8) must be received no earlier than January 15, 2025, and no later than February 14, 2025. All director nominations and shareholder proposals must comply with the requirements of the Company's By-Laws, a copy of which may be obtained at no cost from the Corporate Secretary of the Company. In addition to complying with the advance notice and other requirements of the Company's By-Laws, shareholders who intend to solicit proxies in support of director nominees other than the Company's nominees must provide timely notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 16, 2025.

Other than the proposals described in this Proxy Statement, the Company does not expect any matters to be presented for a vote at the Annual Meeting. If you grant a proxy, the persons named as proxy holders on the proxy card will have the discretion to vote your shares on any additional matters properly presented for a vote at the Annual Meeting. If for any unforeseen reason, any one or more of the Company's nominees is not available as a candidate for director, the persons named as proxy holders will vote your proxy for such other candidate or candidates as may be nominated by the Board of Directors.

The chairman of the meeting may refuse to allow the transaction of any business not presented beforehand or made in compliance with the foregoing procedures, or to acknowledge the nomination of any person not made in compliance with the foregoing procedures.

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS
AND THE ANNUAL MEETING

Q:    Why am I receiving these materials?

A:    We are providing these proxy materials to you in connection with the solicitation by the Board of Directors of BankUnited, Inc., of proxies to be voted at the Company's virtual Annual Meeting. You are receiving this Proxy Statement because you were a BankUnited, Inc. shareholder as of the close of business on the Record Date. This Proxy Statement provides notice of the virtual Annual Meeting, describes the four proposals presented for shareholder action and includes information required to be disclosed to shareholders.

Q:    How do I get electronic access to the proxy materials?

A:    This Proxy Statement and the Company's Annual Report to Shareholders are available on our website at https://ir.bankunited.com. If you are a shareholder of record, you may elect to receive future annual reports or proxy statements electronically by registering your email address at www.proxyvote.com. If you hold your shares in street name, you should contact your broker, bank or other nominee for information regarding electronic delivery of proxy materials. An election to receive proxy materials electronically will remain in effect for all future annual meetings unless revoked. Shareholders requesting electronic delivery may incur costs, such as telephone and internet access charges, that must be borne by the shareholder.

Q:    What proposals will be voted on at the Annual Meeting?

A:    There are four proposals scheduled to be voted on at the virtual Annual Meeting:

•To elect nine directors identified in this Proxy Statement to the Board of Directors to serve until the next annual meeting of shareholders and until that person's successor is duly elected and qualified, or until that person's earlier death, resignation or removal.

•To ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for 2024.

•To approve, on an advisory basis, the compensation of our named executive officers.

•To vote, on an advisory basis, on the frequency of the shareholder vote to approve the compensation of our named executive officers in the future.

82

BankUnited, Inc. 2024 Proxy Statement

Q:    What is the Board of Directors' voting recommendation?

A:    The Company's Board of Directors recommends that you vote your shares:

•"FOR" each of the nominees to the Board of Directors.

•"FOR" the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for 2024.

•"FOR" the approval, on an advisory basis, of the compensation of our named executive officers.

•"EVERY ONE YEAR" on the frequency of the shareholder vote to approve the compensation of our named executive officers in the future.

Q:    Who is entitled to vote?

A:    All shares owned by you as of the close of business on March 18, 2024 (the "Record Date") may be voted by you. You may cast one vote per share of common stock that you held on the Record Date. These shares include shares that are:

•held directly in your name as the shareholder of record; and

•held for you as the beneficial owner through a broker, bank or other nominee.

On the Record Date, BankUnited, Inc. had 74,774,024 shares of common stock issued and outstanding.

Q:    What is the difference between holding shares as a shareholder of record and as a beneficial owner?

A:    Many of our shareholders hold their shares through a broker, bank or other nominee rather than directly in their own name. As summarized below, there are some differences between shares held of record and those owned beneficially.

Shareholder of Record. If your shares are registered directly in your name with the Company's transfer agent, Computershare, you are considered, with respect to those shares, the shareholder of record, and these proxy materials are being sent directly to you by the Company. As the shareholder of record, you have the right to grant your voting proxy directly to certain officers of BankUnited, Inc. or to vote at the virtual Annual Meeting. The Company has enclosed or sent a proxy card for you to use. You may also vote on the internet or by telephone, as described below under the heading "How can I vote my shares without attending the virtual Annual Meeting?"

Beneficial Owner. If your shares are held in an account by a broker, bank or other nominee, like many of our shareholders, you are considered the beneficial owner of shares held in street name, and these proxy materials were forwarded to you by that organization. As the beneficial owner, you have the right to direct your broker, bank or other nominee how to vote your shares, and you are also invited to attend the virtual Annual Meeting.

Since a beneficial owner is not the shareholder of record, you may not vote your shares at the virtual Annual Meeting unless you obtain a "legal proxy" from the broker, bank or other nominee that is the shareholder of record of your shares giving you the right to vote the shares at the virtual Annual Meeting. If you will not be attending the virtual Annual Meeting, you may vote by proxy. You may vote by proxy over the internet or by telephone, as described below under the heading "How can I vote my shares without attending the virtual Annual Meeting?"

Q:    How can I vote my shares at the virtual Annual Meeting?

A:    Shareholder of Record. Shares held directly in your name as the shareholder of record may be voted at the virtual Annual Meeting. You will need to have the 16-digit control number to vote your shares at the virtual Annual Meeting.

    Beneficial Owner. Shares held in street name may be voted at the virtual Annual Meeting. You will need the 16-digit control number provided on the instructions that accompanied your proxy materials to vote your shares at the virtual Annual Meeting.

Q:    How can I vote my shares without attending the virtual Annual Meeting?

A:    Whether you hold your shares directly as the shareholder of record or beneficially own your shares in street name, you may direct your vote without attending the virtual Annual Meeting by voting in one of the following manners:

•Internet. Go to the website listed on your proxy card or voting instruction card and follow the instructions there. You will need the control number included on your proxy card or voting instruction form;

•Telephone. Dial the number listed on your proxy card or your voting instruction form. You will need the control number included on your proxy card or voting instruction form; or

•Mail. Complete and sign your proxy card or voting instruction card and mail it using the enclosed, prepaid envelope.

84

BankUnited, Inc. 2024 Proxy Statement

If you vote on the internet or by telephone, you do not need to return your proxy card or voting instruction card. Internet and telephone voting for shareholders will be available 24 hours a day and will close at 11:59 p.m., Eastern Time, on May 14, 2024.

Q:    What is the quorum requirement for the Annual Meeting?

A:    A quorum is necessary to hold a valid Annual Meeting. A quorum exists if the holders of a majority of the Company's capital stock issued and outstanding and entitled to vote thereat are present at the virtual Annual Meeting or represented by proxy. Abstentions and broker non-votes are counted as present for determining whether a quorum exists. A broker non-vote occurs when an intermediary holding shares for a beneficial owner does not vote on a particular proposal because the intermediary does not have discretionary voting power for that particular proposal and has not received instructions from the beneficial owner.

Q:    What happens if I do not give specific voting instructions?

A:    Shareholder of Record. If you are a shareholder of record and you submit a signed proxy card or submit your proxy by telephone or the internet but do not specify how you want to vote your shares on a particular proposal, then the proxy holders will vote your shares in accordance with the recommendations of the Board of Directors on all matters presented in this Proxy Statement. With respect to any other matters properly presented for a vote at the virtual Annual Meeting, the proxy holders will vote your shares in accordance with their best judgment.

Beneficial Owners. If you are a beneficial owner of shares held in street name and do not provide the broker, bank or other nominee that holds your shares with specific voting instructions, under the rules of the NYSE, the broker, bank or other nominee that holds your shares may generally vote on routine matters but cannot vote on non-routine matters such as the election of directors. If the broker, bank or other nominee that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, the broker, bank or other nominee that holds your shares will inform the inspector of election that it does not have the authority to vote on this matter with respect to your shares. This is generally referred to as a "broker non-vote." Therefore, we urge you to give voting instructions to your broker. Shares represented by such broker non-votes will be counted in determining whether there is a quorum. Because broker non-votes are not considered entitled to vote, they will have no effect on the outcome on non-routine matters other than reducing the number of shares present at the virtual annual meeting or by proxy and entitled to vote from which a majority is calculated for proposals that require the approval of a majority of the shares represented at the meeting and entitled to vote on the proposal.

Q:    Which proposals are considered "routine" or "non-routine"?

A:    The ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for 2024 (Proposal No. 2) is a matter considered routine under applicable rules. A broker or other nominee may generally vote on routine matters, and therefore no broker non-votes are expected to exist in connection with Proposal No. 2.

    The election of directors (Proposal No. 1), the advisory vote to approve the compensation of our named executive officers (Proposal No. 3) and the advisory vote on the frequency of the shareholder vote to approve the compensation of our named executive officers in the future (Proposal No. 4) are matters considered non-routine under applicable rules. A broker or other nominee cannot vote without instructions on non-routine matters, and therefore there may be broker non-votes with respect to each of Proposal No.1, Proposal No. 3 and Proposal No. 4.

85

BankUnited, Inc. 2024 Proxy Statement

Q:    What is the voting requirement to approve each of the proposals?

A:     Proposal 1: Nine directors have been nominated for election at the virtual Annual Meeting. Each director will be elected by a majority of the votes cast, either in attendance or by properly authorized proxy, in the election of directors at the virtual Annual Meeting. Shareholders cannot cumulate votes in the election of directors. Abstentions and broker non-votes will have no effect on this proposal.

An incumbent director nominee who fails to receive the affirmative vote of a majority of the votes cast will be required to tender his or her resignation for the consideration of the Board. The Board’s Nominating and Corporate Governance Committee would then make a recommendation to the Board as to whether to accept or reject the resignation, or as to any other action to be taken. Upon such recommendation and any other factors it may deem appropriate and relevant, the Board will then make a determination regarding the director’s resignation within ninety days of the certification of the election results and publicly disclose its determination.

    Proposal 2: The ratification of the appointment of our independent registered public accounting firm requires the affirmative vote of a majority of the votes represented at the meeting and entitled to vote on the proposal. In accordance with Delaware law, only votes cast "for" a matter constitute affirmative votes. A properly executed proxy marked "abstain" with respect to the ratification of the appointment of our independent registered public accounting firm will not be voted, although it will be counted for purposes of determining whether there is a quorum. Since abstentions will not be votes cast "for" the ratification of the appointment of our independent registered public accounting firm, they will have the same effect as negative votes or votes against that matter.

    Proposal 3: The advisory vote to approve the compensation of our named executive officers requires the affirmative vote of a majority of the votes represented at the meeting and entitled to vote on the proposal. Similar to the vote to ratify the appointment of our independent registered public accounting firm, abstentions will also have the effect of a vote against approval of the compensation of our named executive officers. Broker non-votes will have no effect on this item.

Proposal 4: The advisory vote on the frequency of the shareholder vote to approve the compensation of our named executive officers in the future - every three (3) years, every two (2) years or every one (1) year - the alternative receiving the greatest number of votes will be the frequency that the shareholders will recommend to the Board of Directors. Abstentions and broker non-votes will have no effect on this item.

Q:    What does it mean if I receive more than one proxy or voting instruction card?

A:    It means your shares are registered differently or are in more than one account. Please provide voting instructions for all proxy and voting instruction cards you receive.

Q:    Who will count the vote?

A:    A representative of Broadridge Financial Solutions, Inc. ("Broadridge") will tabulate the votes and act as the inspector of election.

Q:    Can I revoke my proxy or change my vote?

A:    Yes. You may revoke your proxy or change your voting instructions at any time prior to the vote at the Annual Meeting by:

•providing written notice to the corporate secretary of the Company;

•delivering a valid, later-dated proxy or a later-dated vote on the internet or by telephone; or

BankUnited, Inc. 2024 Proxy Statement

•attending the virtual Annual Meeting and voting online at www.virtualshareholdermeeting.com/BKU2024

    Please note that your attendance at the virtual Annual Meeting will not cause your previously granted proxy to be revoked unless you specifically so request. Shares held in street name may be voted by you at the virtual Annual Meeting only if you obtain a signed proxy from the stockholder of record giving you the right to vote the shares.

Q:    Who will bear the cost of soliciting votes for the Annual Meeting?

A:    The Company will pay the entire cost of preparing, assembling, printing, mailing and distributing these proxy materials. In addition to the mailing of these proxy materials, the solicitation of proxies or votes may be made in person, by telephone or by electronic and facsimile transmission by our directors, officers and employees, who will not receive any additional compensation for such solicitation activities. In addition, the Company may reimburse its transfer agent, brokerage firms and other persons representing beneficial owners of shares of BankUnited, Inc.'s common stock for their expenses in forwarding solicitation material to such beneficial owners. We have also retained Innisfree M&A Incorporated to assist in the solicitation of proxies at an anticipated approximate cost of $10,000 plus reasonable out-of-pocket expenses.

Q:    I share an address with another shareholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials?

A:    The Company has adopted a procedure called "householding," which the SEC has approved. Under this procedure, we deliver a single copy of this Proxy Statement and the Annual Report to multiple shareholders who share the same address unless we received contrary instructions from one or more of the shareholders. This procedure reduces the Company's printing costs, mailing costs and fees. Shareholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written or oral request, a separate copy of this Proxy Statement and the Annual Report will be promptly delivered to any shareholder at a shared address to which the Company delivered a single copy of any of these documents. To receive a separate copy of this Proxy Statement or the Annual Report, or to receive a separate copy of our proxy materials in the future, shareholders may write or call the Company at the following address and telephone number:

BankUnited, Inc.

Attn: Investor Relations

Shareholders who hold shares in street name (as described above) may contact their broker, bank or other nominee to request information about householding. Shareholders sharing an address can request delivery of a single copy of our proxy materials if they are currently receiving multiple copies by following the same procedures outlined above.

Q:    How can I obtain a copy of BankUnited, Inc.'s Annual Report on Form 10-K?

A:    Copies of the Company's Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the SEC, are available to shareholders free of charge on BankUnited, Inc.'s website at https://ir.bankunited.com or by writing to BankUnited, Inc., Attn: Investor Relations, 14817 Oak Lane, Miami Lakes, FL 33016.

NON-GAAP FINANCIAL MEASURES

Non-performing assets to total assets, excluding the guaranteed portion of SBA loans is a non-GAAP financial measure. Management believes this measure is relevant to ensure a meaningful basis for comparison to other financial institutions and to provide a more accurate representation of the nature and level of risk reflected in the ratio. The guaranteed portion of SBA loans carry nominal risks, as they are government-insured. The following table reconciles the non-GAAP financial measurement of non-performing assets to total assets, excluding the guaranteed portion of SBA loans to the comparable GAAP measurement of non-performing assets to total assets at the dates indicated (dollars in thousands):

	December 31, 2023			December 31, 2022			December 31, 2021

Compensation Actually Paid vs. Total Shareholder Return

Relationship Between PEO and Average Non-PEO NEOs Compensation Actually Paid and Company TSR

The following chart sets forth the relationship between the amount of Compensation Actually Paid to our PEO, the average amount of Compensation Actually Paid to our Non-PEO NEOs, and the Company's cumulative TSR over the four most recently completed fiscal years.

Compensation Actually Paid vs. Net Income

Relationship Between PEO and Average Non-PEO NEOs Compensation Actually Paid and Net Income

The following chart sets forth the amount of Compensation Actually Paid to our PEO, the average amount of Compensation Actually Paid to our Non-PEO NEOs, and our net income during the four most recently completed fiscal years.

Compensation Actually Paid vs. Company Selected Measure

Relationship Between PEO and Average Non-PEO NEOs Compensation Actually Paid and the Ratio of NIDDA/Total Deposits

The ratio of NIDDA/Total Deposits, the company selected measure included in the Pay Versus Performance Table, directly impacted compensation actually paid as it was a performance measure used in determining the amount of AIP awards for 2023. While the ratio of NIDDA/Total Deposits declined from 12/31/21 to 12/31/23, this decline was expected as it was consistent with industry trends, the interest rate environment, and restrictive monetary policy. Comparatively, the Company's ratio of NIDDA/Total Deposits declined by 4.7% from 12/31/21 to 12/31/23 while this ratio for the population of banks with between $20 billion and $50 billion in total assets declined by an average of 7.1%. Over the period 12/31/19 (the start of the periods presented in the Pay Versus Performance Table) to 12/31/23, the Company's ratio of NIDDA/Total Deposits improved by 8.1% compared to average improvement of 0.4% for the population of banks with between $20 billion and $50 billion of total assets. The level of NIDDA impacts the Company's long-term earnings performance because it directly impacts the cost of funds and the net interest margin, which in turn directly impact net income and earnings per share. This measure is also important because it is closely aligned with the Company's currently most significant strategic priority, growing non-interest bearing deposits.

Total Shareholder Return Vs Peer Group

Relationship Between Company TSR and KBW Regional Index TSR

The following chart compares our cumulative TSR over the four most recently completed fiscal years to that of the KBW Nasdaq Regional Banking Index over the same period.

The chart above illustrates that while the Company's stock outperformed the index for approximately the first 2 1/2 years of the four-year period presented and underperformed the index over the final 1 1/2 years, on a cumulative basis, the Company's stock has performed consistently with the KBW Regional Bank Index over the periods presented.
