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 nine 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. Each elected director's term will last until the 2021 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.

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 the vote of a plurality of the votes cast at any meeting of the shareholders at which directors are to be elected and a quorum is present.

BankUnited, Inc. 2020 Proxy Statement



Board Nominations

Board candidates are selected based on various criteria including their character and reputation, relevant business experience and acumen and relevant educational background. 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.

OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" THE ELECTION OF THE FOREGOING NINE NOMINEES TO THE BOARD OF DIRECTORS

BankUnited, Inc. 2020 Proxy Statement



BOARD OF DIRECTORS AND CORPORATE GOVERNANCE



Role of Board of Directors

The Company's business and affairs are managed under the direction 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, evaluates the Company's 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 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 http://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:

Ÿ 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; and (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;

Ÿ 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

BankUnited, Inc. 2020 Proxy Statement

Ÿ 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 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 March 2020. 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, with the exception of Rajinder P. Singh. Mr. Singh is our Chairman, President and Chief Executive Officer. In making the determination that Dr. Sobti is independent of the Company and its management, the Board of Directors considered that Dr. Sobti is a senior advisor to Credit Suisse, which is a full-service financial institution that, with its affiliates, had directly and indirectly engaged, and may in the future engage, in financial advisory, investment banking and commercial banking services for us and our affiliates, for which it received, or may receive, customary compensation, fees and expense reimbursement. The Board considered that Dr. Sobti is not an employee of Credit Suisse and also has had an independent consulting business since 2007. 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, which was former counsel of the Company, and may in the future engage in legal services for us and our affiliates, for which it received, or may receive, customary compensation, fees and expense reimbursement.



Board of Directors Meetings and Attendance

The Board of Directors held seven meetings during 2019 and acted by written consent five times. Each director attended 75% or more of the meetings of the Board of Directors and Board committees on which they served during 2019 . Directors are expected to attend all meetings of shareholders. All directors attended the 2019 annual meeting.

BankUnited, Inc. 2020 Proxy Statement



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 and our directors also attend conferences and round tables hosted by our primary banking regulators.



Committees of the Board of Directors

The Board has established four committees to facilitate its oversight responsibilities; an Audit Committee, a Risk Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. A description of each Board committee is set forth below.

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 the guidelines for the aggregate levels of acceptable risks 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 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 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

BankUnited, Inc. 2020 Proxy Statement

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.

The Risk Committee also has responsibility for monitoring risks related to information security and cybersecurity and overseeing management's approach to effectively addressing these risks. On a routine basis, the Risk Committee reviews the Company's Information Security Program and regular reporting related to emerging risks and risk metrics in this area. The Risk Committee receives reports from either the Chief Information Security Officer or the Chief Risk Officer and reviews the Information Security Program Annual Report to the Board as well as results of audits of controls and procedures related to information security.

The Risk Committee also reviews regular reporting related to credit, interest rate, liquidity, operational 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 risks, which could impact our financial position and reputation. The Nominating and Corporate Governance Committee is responsible for overseeing the management of risks associated with the independence of our Board.

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.

BankUnited, Inc. 2020 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 Chief Executive Officer ("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 was appointed in May 2019 by our independent directors following the departure of Eugene F. DeMark who did not seek reelection to our Board. Mr. Pauls brings extensive banking and risk management experience to our Board and 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 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 32 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, Compensation and Nominating and Corporate Governance Committee is composed solely of independent directors. Independent directors, therefore, oversee essential, risk-sensitive matters such as the

BankUnited, Inc. 2020 Proxy Statement

quality and integrity of our financial statements; the compensation of our executive officers, including the CEO; the nomination of directors; and the evaluation of the Board, its committees, and its members.

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 2019 , 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.

BankUnited, Inc. 2020 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 accounting controls 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).

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 http://ir.bankunited.com. We expect that any amendments to these codes, or any waivers of their requirements, will be disclosed on our website.



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.

Cash-Based Compensation and Director Compensation Changes Approved in 2019

The Compensation Committee retained Deloitte Consulting, LLP ("Deloitte Consulting") to provide advice regarding non-employee director compensation in March 2019. As one point of reference, Deloitte Consulting reviewed director compensation for directors in BankUnited's Peer Group, as described in "Compensation Discussion and Analysis". In addition to reviewing peer data, Deloitte Consulting and the Compensation Committee considered market and leading practices with respect to director compensation. Based on this review, the Compensation Committee recommended changes to the Company's director compensation program, which were approved by the Board and became effective at the time of the 2019 annual meeting.

BankUnited, Inc. 2020 Proxy Statement

On May 15, 2019, our Board revised our director compensation program by reducing the annual cash retainer from $100,000 to $70,000 annually. The Board also reduced the annual cash retainer for the Chairs of the Audit and the Risk Committees from $75,000 to $35,000. No changes were made to the $25,000 annual cash retainer for the Chairs of the Compensation and Nominating and Corporate Governance Committees. Cash retainers are paid in installments and were prorated effective June 1, 2019 based on the revised fees.

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.

Stock-Based Compensation

The Board further approved changes to the stock-based compensation of the non-employee directors. In past years, including 2018, each non-employee director received an annual grant of 1,000 shares of restricted common stock as well as an additional grant of 2,000 shares of restricted common stock to the Lead Independent Director. In its 2019 review of non-employee director compensation, the Board approved a change from a fixed amount of shares of restricted stock granted annually to an annual grant of restricted common stock with a grant date fair market value equal to the annual cash retainer.

On May 15, 2019, our Board approved a grant of 2,045 shares of restricted common stock (grant date fair value: $70,000) to each non-employee director elected at the 2019 annual meeting to serve a term ending at the 2020 annual meeting. Mr. Pauls received an additional grant of 1,023 shares of restricted common stock (grant date fair value: $35,017) for his service as Lead Independent Director. Each director's restricted common stock grant vests in full on the earlier of the first anniversary of the date of grant or the date of the next annual meeting of shareholders, subject to the director's continued service as a director through the vesting date, except for accelerated vesting in the event of a director's death or disability and in certain circumstances relating to a change in control of the Company.

The following table shows compensation paid, earned or awarded to each of the non-employee members of our Board for 2019 .

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

•

Under our stock retention requirements, directors are required to own shares of the Company's stock with a market value of five times the current annual retainer of $70,000. Under the requirements of the program, the director will not sell equity other than to cover taxes related to the vesting of an equity awards if, after giving effect to such sale, his or her respective retained equity (including vested and unvested equity) has a value that is less than the required multiple for the annual cash retainer.


•	The Company's Insider Trading Policy prohibits directors and executive officers of the Company 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, as well as pledging of the Company's securities as collateral for a loan or from holding securities in a margin account.



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 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. 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

BankUnited, Inc. 2020 Proxy Statement

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. Pursuant to the Company's Amended and Restated By-Laws, shareholders who wish to nominate a candidate for consideration by the Nominating and Corporate Governance Committee for election at the 2021 annual meeting may do so by delivering written notice, no earlier than January 15, 2021 and no later than February 14, 2021, of such nominees' names to BankUnited, Inc., 14817 Oak Lane Miami Lakes, FL 33016, Attention: Corporate Secretary.

The notice must also include a representation that the shareholder giving the notice intends to appear in person or by proxy at the 2021 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.

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 http://ir.bankunited.com, as Annex B to our Corporate Governance Guidelines.

The Company had no Related Party Transactions to report for 2019.

PROPOSAL NO. 2



RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Proposal

The Audit Committee has appointed KPMG LLP to serve as BankUnited, Inc.'s independent registered public accounting firm for its fiscal year ending December 31, 2020. The Audit Committee and the Board of Directors seek to have the shareholders ratify the Audit Committee's appointment of KPMG LLP, which has served as BankUnited, Inc.'s independent registered public accounting firm or independent auditor since 2009. 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 KPMG 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 KPMG LLP.

Representatives of KPMG 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 2020.



Report of the Audit Committee

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 reporting process, including the establishment and maintenance of the system of internal control over financial reporting. KPMG LLP, the Company's independent registered public accounting firm, is 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 KPMG 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 KPMG 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 KPMG 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 KPMG LLP's communications with the Audit Committee concerning independence. The Audit Committee has concluded that KPMG LLP is independent from the Company and its management.

BankUnited, Inc. 2020 Proxy Statement

The Audit Committee meets with the Chief Financial Officer in regular sessions and with representatives of KPMG 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 programs.

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, 2019 , for filing with the SEC.

Key Compensation Decisions Made for 2019 and 2020

Our Compensation Committee implemented certain modifications to our executive compensation program for 2019 and 2020 to better promote the creation of long-term shareholder value and to better align our executive compensation program with current best practices. These changes included:


•	Extended the vesting term of 2019 RSU and PSU awards from three years to four years, subject to the executive's continued service.


•	Adjusted the performance grid of the Long Term Equity-Based Incentive Program (LTIP) for 2020 such that a target payout requires performance at the 50 ^th percentile relative to the Company’s peer group.


•	Provided that equity awards granted after March 1, 2019 will be subject to "double-trigger" vesting provisions in the event of a change in control.

In addition, in determining 2019 AIP awards, the Compensation Committee exercised negative discretion to pay at the target level, despite the achievement of performance at a level that would have resulted in payment at the maximum level.

Except as noted, the executive compensation decisions and payments described in this Proxy Statement were made before the extent of the impact of the COVID-19 pandemic became apparent. The Compensation Committee will consider the business and financial impact to the Company, our shareholders and our employees in making compensation decisions for 2020 and when evaluating 2020 performance in early 2021.

BankUnited, Inc. 2020 Proxy Statement

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 by avoiding undue emphasis on any one metric or short-term goal and having a cap on incentive payments.

Key Elements of our Executive Compensation Program:



Emphasis on Pay for Performance	Attract and Retain Key Executives	Align Interests of our Executives with those of our Shareholders	Balance Risk and Reward - Discourage Inappropriate Risk Taking

Best Practices in Executive Compensation

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



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; all 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 Require equity ownership and retention - CEO equals 6 times base salary and other NEOs equals 3 times base salary	r Do not pay dividends or dividend equivalents on performance stock units (PSUs) or restricted stock units (RSUs) until vested
ü Have a recoupment 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 NEO's compensation opportunity in the form of incentive awards, aligning compensation with the Company's performance
ü All equity awards granted after March 1, 2019 are subject to "double-trigger" vesting provisions upon a change in control

Consideration of Say-on-Pay Vote Results and 2019 Shareholder Engagement Program

At our most recent annual meeting of shareholders, held on May 15, 2019, the Company conducted an advisory vote to approve its executive compensation for the fiscal year ended December 31, 2018. Shareholders approved the compensation of our NEOs, with 66% of the votes present in person or represented by proxy at the meeting and entitled to vote on the matter cast to approve our 2018 executive compensation proposal. We were disappointed in this outcome as this level of support was a significant decline from the 2018 vote, when approximately 98% of the votes cast were in favor of our executive compensation proposal and we had made no significant changes to the structure of our executive compensation program.

Although we have regular, ongoing communications with many of our shareholders, at the direction of the Compensation Committee, we conducted an extensive shareholder engagement program led by Mr. Pauls, our lead independent director, in the fall of 2019. Mr. Dowling, the Chair of our Compensation Committee, also participated in our shareholder engagement program. We held the calls in the fall so that the Compensation Committee could consider shareholder perspectives in determining plan design and performance goals for 2020. When reaching out to our shareholders we asked them to provide us with feedback on our executive compensation programs and our corporate governance practices as well as any other matters of interest to the shareholder.

In calls led by Mr. Pauls, we spoke with the holders of 37% of our total outstanding shares. None of the investors we spoke with expressed any concerns with the overall compensation paid to our executives, and the substantial majority of shareholders we spoke with did not object to any of the features of our compensation plans. We received valuable feedback from our shareholders about our compensation plans and their views about best practices for executive compensation generally. Some of the investors we spoke with thought that one area the Compensation Committee should reconsider was the payout grid associated with our LTIP. This shareholder feedback informed the decision by our Compensation Committee to adjust the LTIP payout grid for 2020 such that target compensation levels can no longer be achieved with less than 50th percentile performance relative to the Company's peer group.

Under our LTIP Program, the Compensation Committee annually establishes equally-weighted performance metrics. Historically the Compensation Committee has used three performance metrics. At the end of the performance period, the Company's performance with respect to each of the equally-weighted performance metrics is assigned a percentile ranking. The amount awarded is determined based on the average

BankUnited, Inc. 2020 Proxy Statement

percentile ranking ("APR") in accordance with a payout grid. The number of PSUs earned at the end of the performance period is determined based on the APR. Payouts are capped at 150% of the executive's target dollar value.

Following the shareholder engagement calls, the Compensation Committee reviewed the design of the LTIP. In March 2020, the Compensation Committee approved the following changes to the performance grid of the LTIP for 2020.

Responding to our Shareholders

WHAT WE HEARD


•	Target payout should require median performance or greater

The Compensation Committee is committed to continuing to be responsive to shareholders' perspectives.



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 executive officers and non-employee directors. Our Compensation Committee meets at least quarterly (six times in person and once by written consent in 2019 ) to approve amounts paid to our executive officers and non-employee directors and administer our incentive plans, 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.

BankUnited, Inc. 2020 Proxy Statement

Role of Management

In evaluating compensation, our Compensation Committee receives and considers information and recommendations from our Chief Executive Officer. 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 Deloitte Consulting as its independent compensation consultant. Deloitte Consulting has worked with the Compensation Committee since 2015 and has assisted 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.

Compensation Peer Group

The Compensation Committee engaged Deloitte Consulting to develop a peer group in 2018. In developing a peer group, Deloitte Consulting reviewed companies that are similar in size based on total assets and market capitalization, have similar business strategies, and compete in the same markets as BankUnited. 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. The peer group was reviewed by the Compensation Committee in 2019, and the only change was the deletion of FCB Financial due to their acquisition by Synovus Financial Corporation in January 2019. The 19 members of the 2019 peer group are:



Bank OZK	Pacwest Bancorp
Bancorpsouth	People's United Financial
Cullen/Frost Bankers	Signature Bank
East West Bancorp	Synovus Financial
FNB Corp	TCF Financial
First Republic Bank	Texas Capital Bancshares
Fulton Financial	UMB Financial Corp
IBERIABANK Corporation	Valley National Bancorp
Investors Bancorp	Western Alliance Bancorporation
New York Community Bank

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.



	Component of Pay	Form of Pay	Objective
Fixed	Base Salary	Cash	To attract and retain key executive talent by providing a level of income security for services rendered during the fiscal year that is not at risk.
At-Risk	Annual Incentive Program	Performance-based cash payment	To reward the achievement of annual financial and other performance related goals, aligning pay with performance.
At-Risk	Long-Term Equity-Based Incentive Program (LTIP)	Restricted Stock Units (RSUs)	To motivate and retain executives by aligning their long-term interests with those of shareholders through sustained performance.
At-Risk	Long-Term Equity-Based Incentive Program (LTIP)	Performance Stock Units (PSUs)

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 of the total target incentive compensation opportunity delivered through long-term incentive compensation.

2019 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 annual incentive awards for Messrs. Singh, Cornish and Bansal and Ms. Lunak. Mr. Richards did not participate in the Annual Incentive Plan in 2019. The Compensation Committee considers the Company's overall strategic objectives when evaluating and establishing performance criteria. The Compensation Committee established the following performance criteria for 2019, measured against the Peer Group:


•	Relative year-over-year percentage growth in revenue, excluding loss-share revenue


•	Relative year-over-year percentage growth in operating expense


•	Relative year-over-year percentage growth in diluted earnings per share (excluding loss share earnings)


•	Relative ratio of non-performing assets to total assets at year-end

For 2018, the annual performance criteria included year-over-year percentage growth in operating net income. The Compensation Committee removed this criteria for 2019. Relative year-over-year percentage growth in operating expense and year-over-year percentage growth in diluted earnings per share (excluding loss share earnings) were added to better align the performance goals with the Company's strategic initiatives. At the end of 2019 , the Company's performance with respect to each of the foregoing measures relative to the 2019 Peer Group was assigned a percentile ranking. All of the performance metrics were weighted equally for purposes of determining the annual incentive payout. The amount awarded was determined based on the average percentile ranking ("APR") in accordance with the following grid. Performance at or above the 75th percentile of the defined peer group would have resulted in the maximum payout.

Committee Exercise of Negative Discretion on the Annual Incentive Plan Performance Results

In reviewing the Company's operating expense growth for 2019, the Compensation Committee members considered the one-time expenses related to the BankUnited 2.0 program and made the determination not to make an adjustment to exclude such expenses in the Company's annual operating expense growth calculation, although adjustments to exclude certain non-recurring expenses were made to some of the peer operating results. In including the one-time expenses, the Company's percentile ranking for operating expense growth was 75.70%, resulting in an overall APR of 73.63% with a target bonus payout. Had the Compensation Committee excluded the one-time expenses related to the BankUnited 2.0 program, the Company's percentile ranking for operating expense growth would have been 86.10% and resulted in an overall APR of 76.23% and a maximum payout.



APR	Payout (% of Target)	Rajinder P. Singh	Leslie N. Lunak	Thomas M. Cornish	Rishi Bansal
0% - 44%	$0	$0	$0	$0	$0
45% - 59%	75%	$1,125,000	$328,125	$708,750	$337,500
60% - 74%	100%	$1,500,000	$437,500	$945,000	$450,000
75% - 100%	150%	$2,250,000	$656,250	$1,417,500	$675,000

BankUnited, Inc. 2020 Proxy Statement

Results for 2019 are summarized below:



	2019 Revenue Growth	2019 Operating Expense Growth	2019 Earnings Per Share Growth	2019 NPA Ratio	APR
BankUnited	12.38%	1.40%	34.32%	0.50
Percentile Ranking	88.30%	75.70%	100.00%	30.50%	73.63%

(1)

For purposes of determining operating net income growth and revenue growth of the Company or its peers, reported amounts may be adjusted to remove the impact of material unusual or non-recurring items. 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. For 2019, BankUnited's operating expenses and net income used in the calculation of earnings per share were adjusted to exclude the impact of a non-recurring $3.8 million pre-tax loss on debt extinguishment. This exclusion did not have an impact on the determination of the amount of the payouts. In calculating BankUnited's ratio of non-performing assets to total assets, the 100% guaranteed portion of SBA loans on non-accrual status totaling $45.7 million and $17.8 million at December 31, 2019 and 2018, respectively, was excluded.


•	For the year ended December 31, 2019 , the APR was calculated at 73.63%, resulting in Annual Cash Incentives being paid at the target level of $1,500,000 for Mr. Singh, $945,000 for Mr. Cornish, $437,500 for Ms. Lunak and $450,000 for Mr. Bansal.



Mr. Richards

In 2019 , 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 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.

On February 14, 2020, the Compensation Committee evaluated the performance of Mr. Richards based on the factors above and approved a cash incentive award in the amount of $350,000.

2019 LTIP Awards



Messrs. Singh, Cornish and Bansal and Ms. Lunak



Time-Based Awards (RSUs)

In 2019 , Messrs. Singh, Cornish and Bansal and Ms. Lunak were eligible to receive an annual grant of RSUs. On March 26, 2019, the Compensation Committee awarded Mr. Singh 37,448 RSUs, with a grant date fair value of $1,250,014, Mr. Cornish 16,515 RSUs, with a grant date fair value of $551,271, Mr. Bansal 9,737 RSUs, with a grant date fair value of $325,021 and Ms. Lunak 9,362 RSUs, with a grant date fair value of $312,504. For purposes of the 2019 RSUs, the Compensation Committee extended the vesting term from three years to four years subject to the executive's continued service. The first one-fourth vested on December 31, 2019, and one-fourth will vest on each of December 31, 2020, 2021 and 2022.

BankUnited, Inc. 2020 Proxy Statement



Performance-Based Awards (PSUs) - Performance Period January 1, 2019 - December 31, 2022

In 2019 , Messrs. Singh, Cornish and Bansal and Ms. Lunak were eligible to receive an annual grant of PSUs. For purposes of the 2019 PSUs, the Compensation Committee extended the performance period, which in prior years had been three years, such that the performance period for the PSUs granted in 2019 commenced on January 1, 2019, and will end on December 31, 2022.


•	Performance will be measured based on the achievement relative to specified peer companies of three equally-weighted performance metrics determined by the Compensation Committee: (a) relative growth in earnings per share, (b) relative 4-year total shareholder return and (c) relative average annual net charge-off ratio.


•	Relative growth in earnings per share and relative net charge-off ratio are measured against the 2019 Peer Group and relative total shareholder return is measured against the banks in the KBW Regional Bank Index at both the beginning and end of the performance period.


•	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 four-year measurement period based on actual performance.


•	At the end of the performance period, the Company's performance with respect to each of the equally-weighted performance metrics will be assigned a percentile ranking. The number of PSUs earned at the end of the performance period will be determined based on the APR.


•	PSU awards will pay out at the maximum level if the Company's performance is at or above the top third of the defined peer groups.


•	Payouts are capped at 150% of the executive’s target dollar value.

Mr. Richards

Mr. Richards did not participate in the LTIP in 2019.

In 2019, Mr. Richards was eligible to receive a restricted stock award in accordance with the Company's Policy on Incentive Compensation Arrangements, the amount of which was determined on the same basis as his annual incentive award. On February 14, 2020, the Compensation Committee evaluated the performance of Mr. Richards and effective March 2, 2020 approved a restricted stock award of 12,000 shares to Mr. Richards, which are scheduled to vest in equal installments on March 2, 2021, 2022, 2023 and 2024, subject to his continued service.

PSUs Granted in February 2017

As previously disclosed in our 2018 proxy statement, Messrs. Singh and Cornish and Ms. Lunak were granted PSUs in February 2017 for the performance period of January 1, 2017 through December 31, 2019. The

BankUnited, Inc. 2020 Proxy Statement

PSU awards were 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.

Performance was measured based on the achievement relative to the 2017 Peer Group of three equally-weighted performance metrics, which were determined by the Compensation Committee: (a) relative growth in tangible book value (3-year compound annual growth rate), (b) total shareholder return and (c) relative net charge-off ratio.

Relative growth in tangible book value and relative net charge-off ratio were measured against the 2017 Peer Group and total shareholder return was measured against the banks in the KBW Regional Bank Index at both the beginning and end of the performance period.

The Compensation Committee reviewed the Company's performance with respect to each of the performance metrics in March 2020 and determined the percentile ranking for each metric relative to the Company's 2017 peer group. The amount awarded was determined based on the APR in accordance with the following grid. The Company's performance resulted in an APR of 62.60% and under the existing payout structure resulted in a payout at the target level.



2017 PSUs - Award Amounts in Number of Shares
APR	Payout (% of Target)	Rajinder P. Singh	Leslie N. Lunak	Thomas M. Cornish
0% - 33%	-%	-	-	-
34% - 66%	100%	24,868	8,312	14,661
67% - 100%	150%	37,301	12,467	21,992

Results for 2017 are summarized below:



	Growth in Tangible Book Value (3-yr CAGR)	Relative 3-year Total Shareholder Return	Relative Net Charge-off Ratio	APR
BankUnited	13.72%	4.16%	0.08%
Percentile Ranking	81.70%	56.10%	50.00%	62.60%



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 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.

BankUnited, Inc. 2020 Proxy Statement

No Excise Tax Gross-Ups and Limited Perquisites

The Company does not provide excise tax gross-ups to its employees. On June 1, 2019, Mr. Singh relinquished exclusive use of a Company provided automobile and driver and now 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 and on balance with the business use, it is expected that the incremental cost to the Company attributable to personal use will be incidental.

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 senior 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 and options) has a value that is less than the required multiple of his or her salary.

Our current guidelines require:



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 requirement. Mr. Bansal became a NEO in 2017 and Mr. Richards became a NEO in 2019 and are still within their respective three year accumulation periods. The stock ownership requirement may be satisfied by:


•	Vested and unvested common stock


•	Vested and unvested stock options


•	Vested and unvested restricted stock units

(1) Value is based on the $18.46 closing price of our stock on record date, March 20, 2020.

Recoupment Policy

The Company has a recoupment policy, which provides that, if we are required to prepare an accounting restatement of our financial statements due to material noncompliance with any reporting requirement, our Board (or a committee thereof) may require reimbursement or forfeiture of incentive-based compensation received by any of our current or former NEOs during the three-year period preceding the date on which we are required to prepare the accounting restatement. The amount to be recouped is based on the excess of the amount of incentive-based compensation paid based on the erroneous financial information over the amount that would have been paid based on the financial information as restated. This policy is in addition to our ability to seek reimbursement or forfeiture of compensation pursuant to the terms of any plan, policy or agreement or applicable law.

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 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. All Covered Persons are prohibited from engaging in any such hedging transactions while in possession of material non-public information regarding the Company.

Tax Implications

Certain of our performance-based incentive compensation programs were designed to permit the Company to deduct compensation expense under Section 162(m) of the Internal Revenue Code, which historically limited the tax deductibility of annual compensation paid to executives to $1 million, unless the compensation qualified as "performance-based," although the Company reserved the right to pay compensation that did not qualify as "performance-based" from time to time. Federal legislation passed on December 22, 2017, repealed the exemption from Section 162(m)'s deduction limit for "performance-based" compensation and the limitation on deductibility generally was expanded to include all individuals who are considered NEOs in any year beginning after December 31, 2016. As a result, compensation paid to our NEOs in excess of $1 million may not be deductible for taxable years commencing after December 31, 2017, other than with respect to payments made pursuant to certain "grandfathered" arrangements entered into prior to November 2, 2017. Further, no assurance can be given that compensation intended to satisfy the requirements for exemption from Section 162(m) in fact will qualify for future tax deductibility. Despite the change in law, the Compensation

BankUnited, Inc. 2020 Proxy Statement

Committee intends to continue to 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.

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 we rely on principles of sound governance and good business judgment in administering our compensation programs.

Based on its assessment in 2019 , 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 was not a NEO in 2017 or 2018.


(2)	For Mr. Richards, the amount reported for 2019 represents a discretionary bonus earned for performance in 2019 and paid during the first quarter of 2020.

(3)

Amounts shown do not reflect the compensation actually realized in 2019 by the NEOs. Instead, amounts represent the aggregate grant date fair value of performance and restricted shares granted to the NEOs during 2019 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, 2019 .

(4)

On March 26, 2019, the Compensation Committee awarded Mr. Singh 37,448 RSUs and 37,448 PSUs, Mr. Cornish 16,515 RSUs and 16,515 PSUs, Ms. Lunak 9,362 RSUs and 9,362 PSUs and Mr. Bansal 9,737 RSUs and 9,737 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 $1,875,021 (as opposed to the target grant date fair value of $1,250,014 reported above); (x) Mr. Cornish would have had a grant date fair value of $826,889 (as opposed to the target grant date fair value of $551,271 reported above); (y) Ms. Lunak would have had a grant date fair value of $468,755 (as opposed to the target grant date of $312,504 reported above); and (z) Mr. Bansal would have had a grant date fair value of $487,515 (as opposed to the target grant date of $325,021 reported above).

(5)

Other than RSUs and PSUs, we typically grant stock awards early in the 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, 2019, Mr. Richards was awarded 10,000 restricted shares for his performance in the 2018 fiscal year and overall contributions to the Company.


(6)	For each of Messrs. Singh, Cornish and Bansal and Ms. Lunak the amounts reported reflect a performance-based cash incentive award earned for performance in 2019 and paid in the first quarter of 2020.

(7)

Includes contributions of $12,600 and $99,900 made by us on Mr. Singh's behalf to our 401(k) plan and Nonqualified Deferred Compensation Plan, respectively, $20,245 for use of a company owned automobile, $48,837 for use of a company paid driver, $5,764 for personal use of the Company's aircraft and $132,124 representing annual service cost recorded by the Company related to Mr. Singh's split-dollar life insurance arrangement. The annual cost of Mr. Singh's split-dollar life insurance is expected to be substantially lower beginning in 2020. In June 2019, Mr. Singh relinquished exclusive use of a Company provided automobile and

(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 2019 , in the following aggregate amounts: $691,678 for Mr. Singh, $787,083 for Ms. Lunak, $224,769 for Mr. Cornish and $569,167 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 2019 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 ranged from 6.08% in 2009 to 6.86% in 2019 . 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. In connection with Mr. Singh's appointment as President and Chief Executive Officer on January 1, 2017, the Company amended his current employment agreement to reflect the change in his title and reporting relationship, the increase in his annual base salary effective January 1, 2017, and to reflect a three-year term, commencing January 1, 2017 (the "Employment Term"). On December 19, 2019, the Company amended Mr. Singh's employment agreement to among other things, extend the term of the agreement for an additional three years commencing on January 1, 2020 and reflect Mr. Singh's current base salary of $1,000,000.

The Employment Term may be extended by mutual agreement of the parties. In the event of the public announcement of a transaction or other event that would constitute a change in control (such announcement, a “Public Announcement”) during the Employment Term, the Employment Term would expire no later than the second anniversary of the change in control, except that the Employment Term would not be automatically extended on or following the date on which such potential change in control were terminated or abandoned.

The employment agreement with Mr. Singh provides that, in the event of his termination of employment by the Company without Cause or by him for Good Reason (as defined in the employment 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 vest on the later of the change in control and the date of termination); (v) continued

BankUnited, Inc. 2020 Proxy Statement

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 employment 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 his employment agreement would automatically convert to time-based RSUs (“Converted RSUs”) that vest at the completion of the three-year performance 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.

Change in Control Agreement with Mr. Richards

Mr. Richards commenced employment with BankUnited, N.A. on January 29, 2018 and has a change of control agreement pursuant to which, he will receive on the date that is six months following consummation of the Change in Control, subject to his continued employment with BankUnited and any successor to BankUnited, a lump sum payment, in an amount equal to: (i) three times his annual base salary, if said Change in Control occurs prior to the first anniversary of his continued employment with BankUnited or (ii) two times his annual base salary, if said Change in Control occurs on or after the first anniversary and prior to the second anniversary of his continued employment with BankUnited or (iii) one time his annual base salary if said Change in Control

BankUnited, Inc. 2020 Proxy Statement

occurs on or after the second anniversary and prior to the third anniversary of his continued employment with BankUnited.

Equity Awards

In the event of a change in control, all outstanding restricted stock awards and RSUs granted prior to March 1, 2019 (other than the equity awards described under "Employment Agreement with Mr. Singh") held by the NEOs that are then unvested would be subject to accelerated vesting, and any performance-based shares to be prospectively awarded with respect to a pending performance period would be granted and vested at target levels. Awards granted after March 1, 2019 (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.

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 31, 2019 ) and calculated using the closing price per share of our common stock on such date ($36.56), and also assumes a cash-out of equity awards in connection with a change in control. The amounts set forth below do not reflect any potential reduction to avoid application of Sections 280G and 4999 of the Internal Revenue Code.

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.

For 2019, our last completed fiscal year:


•	We determined that, as of December 31, 2019 our employee population consisted of approximately 1,529 full- and part-time employees, all of whom were located in the United States. We have no seasonal or temporary 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 2019. In making this determination, we annualized the compensation of approximately 164 full-time employees and part-time employees who were hired in 2019 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 2019 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 2019 Summary Compensation Table included in the 2020 Proxy Statement.

For 2019 , our last completed fiscal year:


•	the median of the annual total compensation of all employees of our company (other than our CEO) was $90,073 and


•	the annual total compensation of our CEO, as reported in the "Total" column of the Summary Compensation Table included elsewhere in this Proxy Statement was $5,320,229 .



	Based on this information, for 2019 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 59.1 to 1.

(4)	These shares are available under the 2010 Plan. The 2009 Plan was frozen on February 12, 2014 and no further awards are available for issuance thereunder.

In connection with the IPO, the Company adopted the 2010 Plan. The 2010 Plan is administered by the Board or a committee thereof and provides for the grant of non-qualified stock options, share appreciation rights, restricted shares, deferred shares, performance shares, unrestricted shares and other share-based awards to selected employees, directors or independent contractors of the Company and its affiliates. The number of shares of common stock authorized for award under the 2010 Plan is 7,500,000, of which 118,847 shares remained available for issuance as of December 31, 2019 .

Shares of common stock delivered under the 2010 and 2014 Plans may consist of authorized but unissued shares or previously issued shares reacquired by the Company. The term of a share option or stock appreciation right issued under the 2010 and 2014 Plans may not exceed ten years from the date of grant and the exercise price may not be less than the fair market value of the Company's common stock at the date of grant. Awards issued prior to March 1, 2019 are subject to full vesting upon a "change in control" (as defined in the 2010 and 2014 Plans). Awards granted after March 1, 2019 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 may be eligible for vesting upon a qualifying termination of employment thereafter.

In March 2020, the Compensation Committee granted awards of 484,830 restricted shares to employees in recognition of their contribution to the Company's performance in fiscal year 2019 and 114,936 restricted shares to Business Unit employees for performance in 2019. On March 13, 2020, the Compensation Committee also approved the issuance of 99,396 shares due to settlement of RSUs and PSUs awarded to Messrs. Singh, Cornish and Bansal and Ms. Lunak. All of the March 2020 issuances were from the 2014 Plan.

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.

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 the 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 2020 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



APPROVAL OF THE AMENDMENT OF THE BANKUNITED, INC. 2014 OMNIBUS EQUITY INCENTIVE PLAN

The Company’s shareholders are being asked to approve amendments to the BankUnited, Inc. 2014 Omnibus Equity Incentive Plan (the “2014 Omnibus Plan”) to 1) increase the number of shares of the Company’s common stock reserved for issuance under the 2014 Omnibus Plan by 2,200,000 shares and 2) extend the termination date of the 2014 Omnibus Plan from May 14, 2024 to May 15, 2030. Both the Compensation Committee and the Board have adopted these amendments, subject to shareholder approval at the annual meeting.

Proposed Amendments to the BankUnited, Inc. 2014 Omnibus Equity Incentive Plan

•

The first proposed amendment will ensure that a sufficient reserve of common stock remains available for issuance under the 2014 Omnibus Plan. As a key element of our compensation program, our equity grants are designed to provide additional incentives to selected management, employees, directors, independent contractors and consultants of the Company or its affiliates in order to retain such persons whose efforts will facilitate the long-term growth and profitability of the Company. The Company relies on equity incentives in the form of stock options, share appreciation rights (“SARs”), restricted shares, deferred shares, performance shares, and other share-based awards. The Company estimates that our remaining share reserve will not be sufficient to permit us to make annual equity grants after 2020. Therefore, the Committee proposes to increase the number of shares of the Company’s common stock reserved for issuance under the 2014 Omnibus Plan from 4,000,000 (of which, 647,276 shares remain available as of the date of this Proxy Statement for issuance pursuant to equity awards that may be granted in the future) to 6,200,000. In determining the number of shares of common stock to reserve under the proposed amendment to the 2014 Omnibus Plan, management and the Compensation Committee evaluated share usage, dilution, overhang, burn rate, and the existing terms of outstanding equity awards, as discussed further in the “Additional Information Regarding Share Increase: Share Usage, Dilution, Burn Rate and Overhang”: The Compensation Committee has determined that 2,200,000 shares are likely to satisfy our compensation needs for at least the next two to three years while maintaining appropriate levels of potential stockholder dilution.


•	The second proposed amendment extends the termination date of the 2014 Omnibus Plan from May 14, 2024 to May 15, 2030. This extension will permit the Company to continue to utilize equity-based compensation as part of our competitive compensation program.

Additional Information Regarding Share Increase: Share Usage, Dilution, Burn Rate and Overhang

The 2,200,000 share increase requested to be approved by shareholders represents 2.38% of our total outstanding common shares as of April 1, 2020. Dilution is the total number of shares subject to equity awards granted (less cancellations) divided by the total outstanding shares.

We manage our long-term dilution by limiting the number of shares subject to equity awards that we grant annually, commonly referred to as burn rate. Burn rate is another measure of dilution that shows how rapidly a company is depleting its shares reserved for equity compensation plans, and differs from annual dilution because it does not take into account forfeitures.

Overview of the Amended 2014 Omnibus Plan

Set forth below is a general description of the material features of the 2014 Omnibus Plan, as amended by the proposed amendments (the “Amended 2014 Omnibus Plan”). This description is qualified in its entirety by reference to the full text of the 2014 Omnibus Plan, which is filed with Appendix A to the Proxy Statement on Schedule 14A of the Company filed April 11, 2014, and the proposed amendment, a copy of which is attached to this Proxy Statement as Appendix A . Shareholders are encouraged to read the 2014 Omnibus Plan in its entirety, a copy of which is attached to this Proxy Statement as Appendix B .

Administration

The Amended 2014 Omnibus Plan may be administered by our Board or by a committee of directors designated by our Board (the "Administrator"). The Administrator has broad administrative authority to interpret the Amended 2014 Omnibus Plan and may prescribe, amend and rescind rules and make all other determinations necessary or desirable for the administration of the Amended 2014 Omnibus Plan. Pursuant to its administrative authority, the Administrator may, among other things: select the persons who will receive awards and determine the types of awards to be granted; determine the terms and conditions of those awards, and amend the terms and conditions of outstanding awards.

BankUnited, Inc. 2020 Proxy Statement

Eligibility for Awards

Employees, directors, independent contractors and consultants of the Company and its affiliates are eligible to receive awards under the Amended 2014 Omnibus Plan. As of April 1, 2020 there were eight non-employee directors and approximately 1,485 employees of the Company and its affiliates who would be eligible to receive awards under the Amended 2014 Omnibus Plan.

Shares Available; Limitations on Awards

As of April 1, 2020, the number of shares of our common stock available for issuance under the Amended 2014 Omnibus Plan is 2,847,031. The aggregate awards granted during any single year to a person who is likely to be a “covered employee” (within the meaning of Section 162(m) of the Internal Revenue Code) may not exceed 1,000,000 shares of our common stock.

The shares of our common stock issued under the Amended 2014 Omnibus Plan may consist of authorized but unissued shares or shares that we may reacquire in the open market, in private transactions, or otherwise. If any shares of common stock subject to an award granted under the Amended 2014 Omnibus Plan are forfeited, cancelled, exchanged or surrendered or if an award otherwise terminates or expires without a distribution of shares to the participant, those shares will again be available for awards under the Amended 2014 Omnibus Plan. Notwithstanding the foregoing, shares surrendered or withheld as payment of either the exercise price of an award (including shares otherwise underlying an award of a SAR that are retained by the Company to account for the grant price of such SAR) and/or withholding taxes in respect of an award will no longer be available for grant under the Amended 2014 Omnibus Plan.

Adjustments for Changes in Capitalization

The Amended 2014 Omnibus Plan provides that, in the event of a merger, consolidation, recapitalization, share dividend or other change in corporate structure affecting our common stock, the Administrator will make, in its sole discretion, an equitable substitution or proportional adjustment in (i) the aggregate number of shares of common stock reserved for issuance under the Amended 2014 Omnibus Plan, (ii) the maximum number of shares of common stock that may be subject to awards granted to a participant in any calendar year, (iii) the kind, number and exercise price subject to outstanding options and SARs granted under the Amended 2014 Omnibus Plan, and (iv) the kind, number and purchase price of shares of common stock subject to outstanding awards of restricted shares, deferred shares, performance shares or other share-based awards granted under the Amended 2014 Omnibus Plan. In addition, in the event of a merger, amalgamation, consolidation, reclassification, spin-off, spin-out, repurchase, reorganization, recapitalization, share dividend or other change in corporate structure affecting the common stock, the Administrator may, in its discretion, terminate all awards in exchange for the payment of cash or in-kind consideration.

Awards

General. The terms and conditions of each award granted under the Amended 2014 Omnibus Plan will be set forth in an award agreement in a form to be determined by the Administrator.

Options. The exercise period of an option may not exceed ten years from the date of grant and the exercise price may not be less than 100% of the fair market value of a share of common stock on the date of grant.

An optionee will have no rights to dividends or distributions or other rights of a stockholder with respect to the shares of common stock subject to an option until the optionee has given written notice of exercise and paid the exercise price and applicable withholding taxes.

Unless the award agreement provides otherwise, in the event of an optionee's termination of employment or service for any reason other than for cause, retirement, disability or death, the optionee's options (to the extent

BankUnited, Inc. 2020 Proxy Statement

exercisable at the time of such termination) generally will remain exercisable until 90 days after such termination and will then expire. Unless the applicable option agreement provides otherwise, in the event of an optionee's termination of employment or service due to retirement, disability or death, the optionee's options (to the extent exercisable at the time of such termination) generally will remain exercisable until one year after such termination and will then expire. Options that were not exercisable on the date of termination of the optionee's employment or service for any reason other than for cause will expire at the close of business on the date of such termination. In the event of an optionee's termination of employment or service for cause, the optionee's outstanding options will expire at the commencement of business on the date of such termination.

Share Appreciation Rights. SARs may be granted under the Amended 2014 Omnibus Plan either alone ("free-standing SAR") or in conjunction with all or part of any option granted under the 2014 Omnibus Plan ("related SAR"). A free-standing SAR granted under the Amended 2014 Omnibus Plan will entitle its holder to receive, at the time of exercise, an amount per share equal to the excess of the fair market value (at the date of exercise) of a share of common stock over a specified price fixed by the Administrator on the date of grant (which shall be no less than fair market value at the date of grant). A related SAR granted under the Amended 2014 Omnibus Plan will entitle its holder to receive, at the time of exercise of the SAR and surrender of the applicable portion of the related option, an amount per share equal to the excess of the fair market value (at the date of exercise) of a share of common stock over the exercise price of the related option. The Administrator may determine to settle the exercise of a SAR in shares of common stock, cash or any combination of both. The exercise price of a SAR may not be less than 100% of the fair market value of a share of common stock on the date of grant. The exercise period of a free-standing SAR may not exceed ten years from the date of grant. The exercise period of a related SAR will expire upon the expiration of its related award.

Participants who are granted SARs shall have no rights as stockholders of the Company with respect to the grant or exercise of such rights.

In the event of a participant's termination of employment or service, free-standing SARs will be exercisable at such times and subject to such terms and conditions as determined by the Administrator in the applicable award agreement, while related SARs will be exercisable at such times and subject to the terms and conditions applicable to the related option.

Restricted Shares, Deferred Shares and Performance Shares. Restricted shares, deferred shares and performance shares may be issued either alone or in addition to other awards granted under the Amended 2014 Omnibus Plan. The Administrator will determine the purchase price and performance objectives, if any, with respect to the grant of restricted shares, deferred shares and performance shares. Subject to the provisions of the Amended 2014 Omnibus Plan and the applicable award agreement, the Administrator has the sole discretion to provide for the lapse of restrictions in installments or the acceleration or waiver of restrictions (in whole or part) under certain circumstances, including the attainment of certain performance goals, a participant's termination of employment or service or a participant's death or disability.

Unless the award agreement provides otherwise, participants with restricted shares and performance shares will generally have all of the rights of a shareholder, including dividend or distribution rights; provided, however that any dividends or dividend equivalents provided with respect to restricted shares, deferred shares or performance shares that are subject to the attainment of specified performance goals will be subject to the same terms, conditions and risk of forfeiture as the underlying awards. Participants with deferred shares will generally not have the rights of stockholders, but, during the restricted period, deferred shares may be credited with dividend or distribution equivalent rights, if the award agreement so provides.

The rights of a participant with respect to restricted shares, deferred shares and performance shares upon termination of the participant's employment or service will be set forth in the applicable award agreement.

BankUnited, Inc. 2020 Proxy Statement

Performance shares may be subject to the achievement of one or more of the following performance goals: (i) earnings, including one or more of operating income, earnings before or after taxes, earnings before or after interest, depreciation, amortization, adjusted EBITDA, economic earnings, or extraordinary or special items, (ii) book value per share (which may exclude nonrecurring items), tangible book value per share and/or growth thereof; (iii) levels of or changes in levels of pre-tax income, after-tax income, net income, net interest income, or fee income; (iv) earnings per share (basic or diluted), core earnings per share and/or growth thereof; (v) operating profit; (vi) revenue, revenue growth or rate of revenue growth; (vii) return measures, including one or more of return on assets (gross or net), return on tangible assets, cash return on assets, cash return on tangible assets, return on investment, return on capital, or return on equity, return on tangible equity, cash return on equity, cash return on tangible equity; (viii) operating expenses; (ix) share price, absolute and/or relative metrics of stock performance, dividends, and/or total capital returned to shareholders; (x) implementation or completion of critical projects or processes; (xi) cumulative earnings per share growth; (xii) levels of or changes in levels of net interest margin, operating margin or profit margin; (xiii) levels of or changes in levels of efficiency ratio or cash efficiency ratio; (xiv) cost targets, reductions and savings, productivity and efficiencies; (xv) levels of or trends in non-performing assets; (xvi) achieving or maintaining specified levels of GAAP and/or regulatory capital; (xvii) levels of or changes in levels of provision, provision rate, net charge-off, or net-charge-off ratio; (xviii) levels of or trends in specified financial statement line items or components thereof, including, but not limited to, cost of deposits, growth of deposits, cost of funds, loan growth, loan yields, or interest earnings asset yields; (xix) strategic business criteria, consisting of one or more objectives based on meeting specified market penetration, geographic business expansion, customer satisfaction, employee satisfaction, human resources management, supervision of litigation, regulatory matters, information technology, and goals relating to acquisitions, divestitures, joint ventures and/or similar transactions, and/or budget comparisons; (xx) personal professional objectives, including any of the foregoing performance goals, the implementation of policies and plans, the negotiation of transactions, the development of long term business goals, formation of joint ventures, and the completion of other corporate transactions; and (xxi) any combination of, or a specified increase in, any of the foregoing.

Other Share-Based Awards. The Administrator may grant other share-based awards upon terms and conditions determined by the Administrator at the date of grant or thereafter.

Treatment of Outstanding Awards upon a Change in Control

The Amended 2014 Omnibus Plan provides that, unless otherwise determined by the Administrator and evidenced in an award agreement, if a change in control occurs, then (i) any unvested or unexercisable portion of an award carrying a right to exercise shall become fully vested and exercisable and (ii) the restrictions, deferral limitations, payment conditions and forfeiture conditions applicable to any other award granted under the Amended 2014 Omnibus Plan will lapse and such unvested awards will be deemed fully vested and any performance conditions imposed with respect to such awards will be deemed to be fully achieved. Notwithstanding the foregoing, with respect to equity awards granted since March 1, 2019, the Compensation Committee has provided that, if such awards are assumed in connection with, or otherwise continued following, a change in control, such awards will not vest automatically in the event of a change in control.

For purposes of the Amended 2014 Omnibus Plan a "change in control" means, in general: (i) a person or entity acquires securities representing 50% or more of our voting power; (ii) certain mergers or amalgamations involving us or any of our subsidiaries and another corporation; (iii) an unapproved change in the majority membership of our Board; (iv) the approval by stockholders of a plan of complete liquidation or dissolution of our company; or (v) the consummation of an agreement for certain sales or dispositions of all or substantially all of our assets.

BankUnited, Inc. 2020 Proxy Statement

Termination of Employment and Service

Unless otherwise provided in an award agreement, upon a participant's termination of employment or service, the participant will forfeit any options to the extent they were not exercisable on the date of such termination. Related SARs shall be exercisable at such time or times and subject to such terms and conditions as the related option. The rights of participants granted free-standing SARs, restricted shares, deferred shares, performance shares or other share-based awards upon a termination of employment or service shall be set forth in the award agreement.

Transferability of Awards

Until such time as the awards are fully vested and/or exercisable in accordance with the Amended 2014 Omnibus Plan or an award agreement thereunder, no purported sale, assignment, mortgage, hypothecation, transfer, charge, pledge, encumbrance, gift, transfer in trust (voting or other) or other disposition of, or creation of a security interest in or lien on, any award or any agreement or commitment to do any of the foregoing by any holder thereof in violation of the provisions of the Amended 2014 Omnibus Plan or an award agreement will be valid, except with the prior written consent of the Administrator, which consent may be granted or withheld in the sole discretion of the Administrator. Unless otherwise determined by the Administrator, an option may be exercised, during the lifetime of the participant, only by the participant or, during any period during which the participant is under a legal disability, by the participant's guardian or legal representative.

Amendment or Termination of Plan

Our Board may amend, alter or terminate the Amended 2014 Omnibus Plan, provided that no such amendment, alteration or termination shall be made that would impair the rights of a participant under any award theretofore granted without such participant's consent.

Determination of Fair Market Value

The fair market value of a share of common stock will be determined by the Administrator in its sole discretion, subject to certain limitations, including if our common stock is admitted to trading on a national securities exchange, the fair market value of a share of common stock will be the closing sales price per share on the applicable date, or if no sale was reported on that date, for the last preceding date on which there was a sale of shares of common stock on the exchange.

Certain Federal Income Tax Consequences

Set forth below is a summary of certain federal income tax consequences of the issuance, receipt, and exercises of options and SARs and the granting and vesting of restricted shares, performance awards and deferred shares, in each case under the Amended 2014 Omnibus Plan. The summary does not purport to cover federal employment tax or other federal tax consequences that may be associated with the Amended 2014 Omnibus Plan, nor does it cover state, local, or non-U.S. taxes. Interested parties should consult their own advisers as to specific tax consequences, including the application and effect of foreign, state and local tax laws.

Options

All options to acquire shares of common stock granted under the Amended 2014 Omnibus Plan are intended to be non-qualified options and are not intended to qualify as "incentive stock options" within the meaning of Section 422 of the Internal Revenue Code. A participant generally will not recognize taxable income upon the grant of an option. Rather, at the time of exercise of the option, the participant will recognize ordinary income for income tax purposes in an amount equal to the excess of the fair market value of the shares of common stock purchased over the exercise price. The Company generally will be entitled to a tax deduction at

BankUnited, Inc. 2020 Proxy Statement

such time and in the same amount that the participant recognizes ordinary income. If the shares of common stock acquired upon the exercise of a non-qualified option are later sold or exchanged, then the difference between the amount received upon such sale or exchange and the fair market value of such shares on the date of such exercise will generally be taxable as long-term or short-term capital gain or loss (if the shares are a capital asset of the optionee), depending upon the length of time such shares were held by the participant.

Share Appreciation Rights

A participant generally will not recognize taxable income upon the grant of a SAR. Rather, at the time of exercise of the SAR, the participant will recognize ordinary income for income tax purposes in an amount equal to the value of any cash received and the fair market value on the date of exercise of any shares of common stock received. The Company generally will be entitled to a tax deduction at such time and in the same amount that the optionee recognizes ordinary income. The participant's tax basis in any shares received will be the fair market value on the date of exercise and, if the shares are later sold or exchanged, then the difference between the amount received upon such sale or exchange and the fair market value of the shares on the date of exercise will generally be taxable as long-term or short-term capital gain or loss (if the shares are a capital asset of the participant) depending upon the length of time such shares were held by the participant.

Restricted Shares and Performance Awards

A participant generally will not be taxed upon the grant of a restricted share or performance award, but rather will recognize ordinary income in an amount equal to the fair market value of the shares at the time the shares are no longer subject to a substantial risk of forfeiture (within the meaning of the Internal Revenue Code). The participant's tax basis in the shares will equal the fair market value of the shares at the time the restrictions lapse, and the participant's holding period for capital gains purposes will begin at that time. Any cash dividends paid on the shares before the restrictions lapse will be taxable to the participant as additional compensation (and not as dividend income). Under Section 83(b) of the Internal Revenue Code, a participant may elect to recognize ordinary income at the time the restricted or performance shares are awarded in an amount equal to their fair market value at that time, notwithstanding the fact that such shares are subject to restrictions and a substantial risk of forfeiture. If such an election is made, no additional taxable income will be recognized by such participant at the time the restrictions lapse, the participant will have a tax basis in the shares equal to their fair market value on the date of their award, and the participant's holding period for capital gains purposes will begin at that time. The Company generally will be entitled to a tax deduction at the time when, and to the extent that, ordinary income is recognized by such participant.

Deferred Shares

In general, the grant of deferred shares will not result in income for the participant or in a tax deduction for the Company. Upon the settlement of such an award, the participant will recognize ordinary income equal to the aggregate value of the payment received, and the Company generally will be entitled to a tax deduction in the same amount.

BankUnited, Inc. 2020 Proxy Statement

Section 162(m) of the Internal Revenue Code

In general, Section 162(m) of the Internal Revenue Code limits the Company’s compensation deduction to $1,000,000 paid in any tax year to any “covered employee” as defined thereunder. Section 162(m) of the Internal Revenue Code may result in all or a portion of the awards granted under the Amended 2014 Omnibus Plan to “covered employees” failing to be deductible to the Company for federal income tax purposes.

Sections 280G and 4999 of the Internal Revenue Code

Awards that are granted, accelerated or enhanced upon the occurrence of a change in control may give rise, in whole or in part, to “excess parachute payments” within the meaning of Section 280G of the Internal Revenue Code and, to such extent, will be non-deductible by the Company and subject to a 20% excise tax payable by the participant under Section 4999 of the Internal Revenue Code.

Section 409A of the Internal Revenue Code

Section 409A of the Internal Revenue Code applies to compensation that individuals earn in one year but that is not paid until a future year. This is referred to as nonqualified deferred compensation. If deferred compensation covered by Section 409A of the Internal Revenue satisfies the requirements thereof, then Section 409A of the Internal Revenue Code has no effect on the individual’s taxes. If a deferred compensation arrangement does not meet the requirements of Section 409A of the Internal Revenue Code, the compensation is subject to accelerated taxation in the year in which such compensation is no longer subject to a substantial risk of forfeiture and certain additional taxes, interest and penalties, including a 20% additional income tax. The Amended 2014 Omnibus Plan permits the grant of various types of incentive awards, which may or may not be subject to Section 409A of the Internal Revenue Code. If an award that is subject to Section 409A of the Internal Revenue Code does not satisfy the requirements thereof, the taxable event for such award could apply earlier than intended and could result in the imposition of additional taxes and penalties on the participant.

New Plan Benefits

Awards under the Amended 2014 Omnibus Plan are made at the discretion of the Compensation Committee. Therefore, the benefits or amounts that will be received by or allocated to each named executive officer, all current executive officers as a group, all directors who are not executive officers as a group, and all employees who are not executive officers as a group, under the Amended 2014 Omnibus Plan if the proposed amendment is approved by shareholders are not presently determinable.

BENEFICIAL OWNERSHIP OF THE COMPANY'S COMMON STOCK

The following table sets forth certain information with respect to the beneficial ownership of the Company's equity securities as of the March 20, 2020 record date: (1) each person or entity, based on information contained in Schedules 13G filed with the SEC, who owns of record or beneficially more than 5% of any class of the Company's voting securities; (2) each of the Company's executive officers and directors; and (3) all of the Company's directors and executive officers as a group. Beneficial ownership is determined in accordance with the rules of SEC. To our knowledge, each shareholder will have sole voting and investment power with respect to the shares indicated as beneficially owned, unless otherwise indicated in a footnote to the following table. Unless otherwise indicated in a footnote, the business address of each person is our corporate address, c/o BankUnited, Inc., 14817 Oak Lane, Miami Lakes, Florida 33016.

In computing the number of shares of common stock beneficially owned by a person and the percentage ownership of that person, we deemed outstanding shares of common stock subject to options or warrants held by that person that are currently exercisable or exercisable within 60 days of March 20, 2020. We did not, however, deem these shares outstanding for the purpose of computing the percentage ownership of any other person. Beneficial ownership representing less than 1% is denoted with an asterisk (*).

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors and executive officers and persons who own more than 10% of the issued and outstanding shares of the Company's common stock to file reports of initial ownership of common stock and other equity securities and subsequent changes in that ownership with the SEC and the NYSE. Based solely on a review of such reports and written representations from the directors and executive officers, the Company believes that all reports that were required to be filed under Section 16(a) during 2019 were timely filed except due to an administrative error by the Company during preparation for Hurricane Dorian, a Form 4 reporting one transaction was filed late on behalf of Mr. Alford.

REQUIREMENTS, INCLUDING DEADLINES, FOR SUBMISSION OF PROXY PROPOSALS, NOMINATION OF DIRECTORS AND OTHER BUSINESS OF SHAREHOLDERS

In order to submit shareholder proposals for the 2021 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 be received by the Corporate Secretary at the Company's principal office in Miami Lakes, Florida, no later than December 11, 2020.

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 2021 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, 2021, and no later than February 14, 2021. 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.

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 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?

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 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?

This Proxy Statement and the Company's Annual Report to Shareholders are available on our website at http://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 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 KPMG LLP as our independent registered public accounting firm for 2020.


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

BankUnited, Inc. 2020 Proxy Statement


•	To approve the amendment of the BankUnited, Inc. 2014 Omnibus Equity Incentive Plan.

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 KPMG LLP as our independent registered public accounting firm for 2020.


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


•	"FOR" the approval of the amendment of the BankUnited, Inc. 2014 Omnibus Equity Incentive Plan.

Q: Who is entitled to vote?


A:	All shares owned by you as of the close of business on March 20, 2020 (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 92,398,989 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 in person at the 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 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 Annual Meeting.

Since a beneficial owner is not the shareholder of record, you may not vote your shares in person at the 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 Annual Meeting. If you do not wish to vote in person or you will not be attending the 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 Annual Meeting?"

Q: How can I vote my 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.

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 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;

BankUnited, Inc. 2020 Proxy Statement

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

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 in person 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?

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 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 New York Stock Exchange (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 in person 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 KPMG LLP as our independent registered public accounting firm for 2020 (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 approval of the amendment to the BankUnited, Inc. Omnibus Equity Incentive Plan (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.

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


A:	Proposal 1: Nine directors have been nominated for election at the Annual Meeting. 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. Shareholders cannot cumulate votes in the election of directors. Abstentions and broker non-votes will have no effect on this proposal.

BankUnited, Inc. 2020 Proxy Statement

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 approval of the amendment to the BankUnited, Inc. 2014 Omnibus Equity Incentive Plan 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 and the advisory vote to approve the compensation of our named executive officers, abstentions will have the effect of a vote against approval of the amendment to the BankUnited, Inc. 2014 Omnibus Equity Incentive Plan. 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


•	attending the virtual Annual Meeting and voting online at www.virtualshareholdermeeting.com/BKU2020

BankUnited, Inc. 2020 Proxy Statement

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.

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

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. Shareholders can contact Innisfree M&A Incorporated at 888-750-5834 to answer any questions they may have regarding voting.


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?

The Company has adopted a procedure called "householding," which the Securities and Exchange Commission (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
14817 Oak Lane
Miami Lakes, FL 33016
(305) 231-6400

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, 2019 , as filed with the SEC, are available to shareholders free of charge on BankUnited, Inc.'s website at http://ir.bankunited.com or by writing to BankUnited, Inc., Attn: Investor Relations, 14817 Oak Lane, Miami Lakes, FL 33016. The Company's 2019 Annual Report on Form 10-K accompanies this Proxy Statement.

BankUnited, Inc. 2020 Proxy Statement

Q: Where can I find the voting results of the Annual Meeting?


A:	BankUnited, Inc. will announce preliminary voting results at the Annual Meeting and publish preliminary results, or final results if available, in a Current Report on Form 8-K within four business days of the Annual Meeting.

Section 9. Restricted Shares, Deferred Shares and Performance Shares.

(a) General . Restricted Shares, Deferred Shares or Performance Shares may be issued either alone or in addition to other Awards granted under the Plan. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, Restricted Shares, Deferred Shares or Performance Shares shall be made; the number of Shares to be awarded; the price, if any, to be paid by the Participant for the acquisition of Restricted Shares, Deferred Shares or Performance Shares; the period of time prior to which such shares become vested and free of restrictions on Transfer (the “ Restricted Period ”), if any, applicable to Restricted Shares, Deferred Shares or Performance Shares; the performance objectives (if any) applicable to Deferred Shares or Performance Shares; and all other conditions of the Restricted Shares, Deferred Shares and Performance Shares. If the restrictions, performance objectives and/or conditions established by the Administrator are not attained, a Participant shall forfeit his or her Restricted Shares, Deferred Shares or Performance Shares, in accordance with the terms of the grant. The provisions of the Restricted Shares, Deferred Shares or Performance Shares need not be the same with respect to each Participant.

(b) Restrictions and Conditions . The Restricted Shares, Deferred Shares and Performance Shares granted pursuant to this Section 9 shall be subject to the following restrictions and conditions and any additional restrictions or conditions as determined by the Administrator at the time of grant or, subject to Section 409A of the Code, thereafter:

(1) The Administrator may, in its sole discretion, provide for the lapse of restrictions in installments and may accelerate or waive such restrictions in whole or in part based on such factors and such circumstances as the Administrator may determine, in its sole discretion, including, but not limited to, the attainment of certain performance related goals, the Participant’s termination of employment or service as a director, independent contractor or consultant to the Company or any Affiliate thereof, or the Participant’s death or Disability; provided , however , that the Administrator may not waive the attainment of Performance Goals in the case of any Award that is intended to qualify as “performance-based compensation” under Section 162(m) of the Code. Notwithstanding the foregoing, upon a Change in Control, the outstanding Awards shall be subject to Section 13 hereof.

BankUnited, Inc. 2020 Proxy Statement

(2) Except as provided in Section 17 or in the applicable Award Agreement, the Participant shall generally have the rights of a shareholder of the Company with respect to Restricted Shares or Performance Shares during the Restricted Period. Except as provided in Section 17 or in the applicable Award Agreement, the Participant shall generally not have the rights of a shareholder with respect to Shares subject to Deferred Shares during the Restricted Period; provided , however , that, subject to Section 409A of the Code, an amount equal to dividends declared during the Restricted Period with respect to the number of Shares covered by Deferred Shares shall be paid to the Participant as set forth in the Award Agreement, provided that the Participant is then providing services to the Company. Any dividends or dividend equivalents provided with respect to Restricted Shares, Deferred Shares, or Performance Shares that are subject to the attainment of specified performance goals will be subject to the same terms, conditions and risk of forfeiture as the underlying Awards. Certificates for Shares of unrestricted shares of Common Stock may, in the Company’s sole discretion, be delivered to the Participant only after the Restricted Period has expired without forfeiture in respect of such Restricted Shares, Deferred Shares or Performance Shares, except as the Administrator, in its sole discretion, shall otherwise determine.

(3) The rights of Participants granted Restricted Shares, Deferred Shares or Performance Shares upon termination of employment or service as a director, independent contractor, or consultant to the Company or to any Affiliate thereof terminates for any reason during the Restricted Period shall be set forth in the Award Agreement.

Section 10. Other Share-Based Awards.

The Administrator is authorized to grant Awards to Participants in the form of Other Share-Based Awards, as deemed by the Administrator to be consistent with the purposes of the Plan and as evidenced by an Award Agreement. The Administrator shall determine the terms and conditions of such Awards, consistent with the terms of the Plan, at the date of grant or thereafter, including any Performance Goals and performance periods. Any dividends or dividend equivalents provided with respect to Other Share-Based Awards that are subject to the attainment of specified performance goals will be subject to the same terms, conditions and risk of forfeiture as the underlying Awards. Common Stock or other securities or property delivered pursuant to an Award in the nature of a purchase right granted under this Section 10 shall be purchased for such consideration, paid for at such times, by such methods, and in such forms, including, without limitation, Shares, other Awards, notes or other property, as the Administrator shall determine, subject to any required corporate action.

Section 11. Performance-Based Awards.

To the extent that the Plan is subject to Section 162(m) of the Code, no payment with respect to an Award made under Section 9 or 10 hereof which is intended to qualify as “performance-based compensation” (within the meaning of Section 162(m) of the Code) shall be made to a Participant that is likely to be a Covered Employee prior to the certification by the Committee that the applicable performance criteria based upon one or more Performance Goals have been attained. Such performance criteria shall be established in writing by the Committee not later than the time period prescribed under Section 162(m) of the Code and the regulations thereunder. All provisions of such Awards that are intended to qualify as “performance-based compensation” (within the meaning of Section 162(m) of the Code) shall be construed in a manner to so comply.

BankUnited, Inc. 2020 Proxy Statement

Section 12. Accelerated Vesting In Connection With a Change in Control.

Unless otherwise determined by the Administrator and evidenced in an Award Agreement, in the event that a Change in Control occurs, then:

(1) any unvested or unexercisable portion of any Award carrying a right to exercise shall become fully vested and exercisable; and

(2) the restrictions, deferral limitations, payment conditions and forfeiture conditions applicable to an Award granted under the Plan shall lapse and such Awards shall be deemed fully vested and any performance conditions imposed with respect to such Awards shall be deemed to be fully achieved.

Section 13. Amendment and Termination.

The Board may amend, alter or terminate the Plan, but no amendment, alteration, or termination shall be made that would impair the rights of a Participant under any Award theretofore granted without such Participant’s consent. Unless the Board determines otherwise, the Board shall obtain approval of the Company’s shareholders for any amendment that would require such approval in order to satisfy the requirements of Section 162(m) of the Code, any rules of the stock exchange on which the Common Stock is traded or other applicable law, including, without limitation, repricing of stock options and option exchanges. The Administrator may amend the terms of any Award theretofore granted, prospectively or retroactively, but, subject to Section 5 of the Plan and the immediately preceding sentence, no such amendment shall impair the rights of any Participant without his or her consent.

Section 14. Unfunded Status of Plan.

The Plan is intended to constitute an “unfunded” plan for incentive compensation. With respect to any payments not yet made to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general creditor of the Company.

Section 15. Withholding Taxes.

Each Participant shall, no later than the date as of which the value of an Award first becomes includible in the gross income of such Participant for federal and/or state income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any federal, state, or local taxes of any kind required by law to be withheld with respect to the Award. The obligations of the Company under the Plan shall be conditional on the making of such payments or arrangements, and the Company shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to such Participant. Whenever cash is to be paid pursuant to an Award granted hereunder, the Company shall have the right to deduct therefrom an amount sufficient to satisfy any federal, state and local withholding tax requirements related thereto. Whenever Shares are to be delivered pursuant to an Award, the Company shall have the right to require the Participant to remit to the Company in cash an amount sufficient to satisfy any related federal, state and local taxes to be withheld and applied to the tax obligations. With the approval of the Administrator, a Participant may satisfy the foregoing requirement by electing to have the Company withhold from delivery of Shares or by delivering already owned unrestricted shares of Common Stock, in each case, having a value not exceeding the minimum federal, state and local taxes required to be withheld and

BankUnited, Inc. 2020 Proxy Statement

applied to the tax obligations. Such Shares shall be valued at their Fair Market Value on the date of which the amount of tax to be withheld is determined. Fractional share amounts shall be settled in cash. Such an election may be made with respect to all or any portion of the Shares to be delivered pursuant to an Award. The Company may also use any other method of obtaining the necessary payment or proceeds, as permitted by law, to satisfy its withholding obligation with respect to any Option or other Award.

Section 16. Transfer of Awards.

Until such time as the Awards are fully vested and/or exercisable in accordance with the Plan or an Award Agreement, no purported sale, assignment, mortgage, hypothecation, transfer, charge, pledge, encumbrance, gift, transfer in trust (voting or other) or other disposition of, or creation of a security interest in or lien on, any Award or any agreement or commitment to do any of the foregoing (each, a “ Transfer ”) by any holder thereof in violation of the provisions of the Plan or an Award Agreement will be valid, except with the prior written consent of the Administrator, which consent may be granted or withheld in the sole discretion of the Administrator. Any purported Transfer of an Award or any economic benefit or interest therein in violation of the Plan or an Award Agreement shall be null and void ab initio , and shall not create any obligation or liability of the Company, and any person purportedly acquiring any Award or any economic benefit or interest therein transferred in violation of the Plan or an Award Agreement shall not be entitled to be recognized as a holder of such Shares. Unless otherwise determined by the Administrator in accordance with the provisions of the immediately preceding sentence, an Option may be exercised, during the lifetime of the Participant, only by the Participant or, during any period during which the Participant is under a legal disability, by the Participant’s guardian or legal representative.

Section 17. Continued Employment.

The adoption of the Plan shall not confer upon any Eligible Recipient any right to continued employment or service with the Company or any Affiliate thereof, as the case may be, nor shall it interfere in any way with the right of the Company or any Affiliate thereof to terminate the employment or service of any of its Eligible Recipients at any time. Awards are subject to any clawback policy adopted by the Company from time to time.

Section 18. Effective Date.

The Plan was adopted by the Board on April 8, 2014, and shall become effective on the date that it is approved by shareholders of the Company (the “ Effective Date ”). No Awards may be granted under the Plan prior to the time that the shareholders have approved the Plan. The approval or disapproval of the Plan by the shareholders of the Company shall have no effect on any other equity compensation plan, program or arrangement sponsored by the Company or any of its Affiliates.

Section 19. Term of Plan.

No Award shall be granted pursuant to the Plan on or after the tenth anniversary of the Effective Date, but Awards theretofore granted may extend beyond that date.

Section 20. Section 409A of the Code.

The intent of the parties is that payments and benefits under the Plan comply with Section 409A of the Code to the extent subject thereto or an exemption therefrom, and, accordingly, to the maximum extent permitted, the Plan shall be interpreted and be administered to be in compliance therewith. Any payments described in the Plan that are due within the “short-term deferral period” as defined in Section 409A of the Code shall not be treated as deferred compensation unless applicable law requires otherwise. Notwithstanding anything to the contrary in the Plan, no payment or distribution under this Plan that constitutes an item of deferred compensation under Section 409A of the Code and becomes payable by reason of a Participant’s termination of employment or service with the Company will be made to such Participant until such Participant’s termination of employment or service constitutes a “separation from service” within the meaning of Section 409A of the Code. Notwithstanding anything to the contrary in the Plan, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A of the Code, amounts that would otherwise be payable and benefits that would otherwise be provided during the six (6) month period immediately following the Participant’s termination of employment shall instead be paid on the first business day after the date that is six (6) months following the Participant’s separation from service (or upon the Participant’s death, if earlier). In addition, each amount to be paid or benefit to be provided to the Participant, which constitutes deferred compensation subject to Section 409A of the Code, shall be construed as a separate identified payment for purposes of Section 409A of the Code. The Company makes no representation that any or all of the payments or benefits described in this Plan will be exempt from or comply with Section 409A of the Code and makes no undertaking to preclude Section 409A of the Code from applying to any such payment. The Participant shall be solely responsible for the payment of any taxes and penalties incurred under Section 409A.

Section 21. Governing Law.

The Plan shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to principles of conflicts of law of such state.
