Your vote is important. Whether or not you plan to attend the Annual Meeting, please read the enclosed proxy statement and vote as soon as possible via the Internet, by telephone or, by mailing the completed Proxy Card or voting instruction form (if you received a Proxy Card or voting instruction form in the mail). Using the Internet or telephone voting systems or mailing your completed Proxy Card will not prevent you from voting your shares during the meeting if you are a stockholder of record and wish to do so. Important information about the matters to be acted upon at the meeting is included in the notice of meeting and proxy statement. I am very much looking forward to our 2020 Annual Meeting of Stockholders. Very truly yours, Rod K. Brenneman Independent Chairman This proxy statement is dated March 31, 2020 and is first being sent or made available to stockholders on or about March 31, 2020.

A letter from our CEO Dear CrossFirst Stockholders, CrossFirst Bank started in 2007 with the mission of serving the financial needs of our clients and a passion for building relationships. This mission inspires our long-term strategy and shapes how we operate as a bank. It’s exciting to see how far we have come as we have just completed the best year in the company’s history, which included a successful IPO and we are now listed on the Nasdaq. I’m so proud of the management team and the employees for delivering on the initiatives that we put in place. In the face of a challenging interest rate environment, we strengthened our year-over-year earnings due to our fantastic teams and proven branch-lite operating model. I am very proud to report our 45% increase in net income in fiscal year 2019, along with a 20% growth in assets, and a 22% increase in the deposit base. Our asset-to-employee ratio stands at an exemplary $13.8 million and our efficiency ratio improved by more than 15% to 58%, in part by managing our non-interest expenses which only rose 2% in 2019. This success exemplifies how every day the people of CrossFirst work hard to deliver extraordinary service through character, competence, commitment, and connections. Making these pillars the basis of who we are is vital because we want to empower our employees and lead with service to create an environment where the client always benefits. Thus, we find the right bankers and invest in their strengths to generate client relationships that exceed expectations. We enter 2020 with a strong capital position and expect our growth strategy will allow us to leverage it in an efficient manner, particularly with our expansions into Frisco, TX and the Plaza in Kansas City, MO later this year. As we move forward in the decade, we are preparing for unprecedented low interest rates, a challenging economic environment for 2020, and continued competition from both non- traditional competitors into the financial services sector and traditional banks. Additionally, COVID-19 has significantly slowed consumer spending that will ultimately impact banking and various sectors of the overall economy. We believe we have positioned the company to effectively manage through a tougher economic cycle in 2020.

While the current economic environment looks grim, we believe in the longer-term trend of the American economy and expect things will recover. We will continue focusing on attracting and developing the highest level of talent, improving our profitability and operating efficiency, employing effective credit and enterprise risk management, and continuing our earnings growth momentum to improve profitability. We remain committed to consistent long-term results and returning value to our shareholders. As I meet with teams across our organization, I continue to be impressed with how well they work together to provide extraordinary service for our customers and am confident in our ability to face the challenges of the future and execute our plan to deliver for our customers, communities, employees, and shareholders. Our management is committed to continuing our mission to provide extraordinary service and ensure our employees are dedicated to our core values. Thank you to everyone who contributed to CrossFirst Bankshares’ success in 2019 and we look forward to building upon our foundation and delivering our goals in 2020. Sincerely, George Jones Chief Executive Officer & President

Board & Governance Matters Board & Governance Matters PROPOSAL 1 - Election of Directors The Board of Directors recommends that you vote “FOR” the election of each Class III director nominee. Proxies solicited by our Board will be voted “FOR” the election of each Class III director nominee unless otherwise instructed. The Board believes strong corporate governance is critical to achieving the Company’s long-term goals and maintaining the trust and confidence of investors, employees, customers, regulatory agencies, and other stakeholders. The Board oversees the Company’s business and directs its management. The non-employee directors of the Board are not involved in day-to-day operations. Instead, the Board meets periodically with management to review the Company’s operating plans, multi-year strategic plan and performance against such plans, risks, and business strategies. Directors also consult with management about the Company’s performance outside of formal meetings, which include opportunities for directors to have in-depth conversations with management about particular areas of the business. All of the Class III director nominees set forth below are standing for election at the Annual Meeting. If elected each such director will serve for a term of three years and will hold office until his or her successor has been duly elected and qualified or the director’s earlier resignation, death or removal. The nominees below are current directors of the Company, and each such nominee has indicated that he or she will serve if elected. We do not anticipate that any nominee will be unable or unwilling to stand for election, but if that happens, your proxy will be voted for another person nominated by the Board. The Board may also choose to reduce the number of directors to be elected, as permitted by our Bylaws. The experience, qualifications, attributes and skills of each of the Company’s director nominees are set forth below. The Board believes that an effective board consists of a diverse group of individuals who bring a variety of complementary skills and experiences. The Nominating and Corporate Governance Committee (“Nominating Committee”) and the Board consider the skills and experiences of the directors in the broader context of the Board’s overall composition, with a view toward constituting a board that has the best skill set and experience to oversee the Company’s business. Our directors have a diversity of experience. They collectively have substantive knowledge and skills applicable to our business, including in the areas of public accounting and financial reporting, finance, risk management, business development, technology, marketing, operations, strategic planning, management development and succession, compensation, corporate governance, and banking. The Nominating Committee regularly reviews the composition of the Board and its assessment of the Board’s performance in light of our evolving business requirements to maintain a Board with the appropriate mix of skills and experiences needed for the broad set of challenges that the Company confronts. Annually, we conduct individual interviews with each director that include topics such as Board and committee performance and effectiveness, and leadership of the Board and committees. The Independent Chairman then reports the results of these interviews to the full Board during its self-evaluation. The full Board evaluates such results. In addition, each committee annually conducts a self-evaluation. The Board of Directors currently consists of 17 directors and is divided into three classes having three-year terms that expire in successive years. Six candidates have been nominated for election as Class III directors at the 2020 Annual Meeting for a three-year term expiring in 2023. Upon recommendation of the Nominating Committee, the Board has nominated Rod Brenneman, George Bruce, Jennifer Grigsby, Lance Humphreys, Mason King, and James Kuykendall for re-election as Class III directors. Biographical information about each of the nominees and continuing directors follows. A discussion of the qualifications, attributes and skills of each nominee that led the Board and the Nominating Committee to the conclusion that he or she should continue to serve as a director follows each of the director and nominee biographies. If you are a stockholder of record and you sign your proxy card or vote by telephone or over the Internet but do not give instructions with respect to the voting of directors, your shares will be voted “FOR” the re- election of Messrs. Brenneman, Bruce, Humphreys, King, and Kuykendall and Ms. Grigsby. Each nominee has accepted such nomination; however, in the event that a nominee is unable or declines to serve as a director at the time of the 2020 Annual Meeting, the proxies will be voted for any nominee who shall be designated by the Board to fill such vacancy. If you wish to give specific instructions with respect to the voting of directors, you may do so by indicating your instructions on your proxy card or when you vote by telephone or over the Internet. If you are a beneficial owner holding your shares in street name and you do not give voting instructions to your broker, bank or other intermediary, that organization will leave your shares unvoted on this matter.

Board & Governance Matters Corporate Governance Process for Nominating Directors Nomination of Directors The Nominating Committee is responsible for identifying, evaluating, and recommending candidates to the Board. The Nominating Committee may consider director candidates from a wide range of sources, including stockholders, officers, and directors. The Board is responsible for nominating directors for election by the stockholders and filling any vacancies on the Board that may occur. The Nominating Committee will continue to evaluate the composition of the Board, including the mix of skills and experiences of existing directors, as well as the potential benefits from new and different perspectives and skill sets. Stockholder Recommendations for Director Candidates Fulfilling its responsibility to identify, evaluate, and recommend director candidates, the Nominating Committee accepts stockholder recommendations of director candidates and evaluates such candidates in the same manner as other candidates. The Nominating Committee determines the need for additional or replacement Board members, then identifies and evaluates the director candidate under the Director Qualifications described below based on the information the Nominating Committee receives with the recommendation or which it otherwise possesses, which may be supplemented by certain inquiries. If the Nominating Committee determines, in consultation with other directors, that a more comprehensive evaluation is warranted, the Nominating Committee may then obtain additional information about the director candidate’s background and experience, including by means of interviews. The Nominating Committee will then evaluate the director candidate further, again using the qualification criteria described herein. The Nominating Committee receives input on such director candidates from other directors, and recommends director candidates to the full Board for nomination. The Nominating Committee may engage a third party to assist in identifying director candidates or to assist in gathering information regarding a director candidate’s background and experience. If the Nominating Committee engages a third party, the Company pays for these services. Stockholders who wish to recommend a candidate for the Nominating Committee’s consideration must submit the recommendation in writing to CrossFirst Bankshares, Inc. 11440 Tomahawk Creek Parkway, Leawood, Kansas, 66211 Attn: General Counsel & Corporate Secretary. The written notice must demonstrate that it is being submitted by a stockholder of record of the Company and include information about each proposed director candidate, including name, age, business address, principal occupation, principal qualifications, and other relevant biographical information. In addition, the stockholder must confirm the candidate’s consent to serve as a director. In 2020, there were no director candidates submitted by stockholders. Stockholders may make recommendations at any time. In addition, stockholders may nominate director candidates by complying with the advance notice bylaw provisions discussed at the end of this Proxy Statement in the “General Information – Stockholder Proposals or Nominations not Submitted Pursuant to Rule 14a-8” section. Director Qualifications Our Corporate Governance Guidelines describe our director qualifications. The Board seeks members who combine a broad and relevant spectrum of experience and expertise with a reputation for integrity. The Board looks for directors that can best perpetuate the Company's success and represent stockholder interests through the exercise of sound judgment, using their diversity of experience. Directors should be selected based upon their potential contributions to the Board and management and their ability to represent the interests of stockholders. Also, the Board will consider the diversity of a candidate’s perspectives, background, and other demographics. When considering potential director candidates, our Board of Directors also considers: (i) whether the individual meets various independence requirements; (ii) the individual’s understanding of banking, the varied disciplines relevant to the success of a publicly traded company in the current business environment and the Company’s business and markets; (iii) the professional expertise, business and financial experience and educational background of the individual; (iv) the individual’s understanding of, and commitment to, high standards of regulatory compliance; (v) the personal and professional integrity of the individual; and (vi) other factors that promote diversity of views and experience. Generally, no director is permitted to serve on more than four public company boards (including the Company’s Board). Management directors may only serve on one other public company board. Our Chairman of the Board may serve on no more than two other public company boards (this is limited to one other board if he is serving as lead director or chairman of another public company board). Proxy Statement Page 9

Board & Governance Matters The Corporate Governance Guidelines include a retirement policy for directors. In general, under this policy, any director who has reached the age of 75 at or before the time for his or her election by stockholders or designation by the Board to the Board will not be eligible for election or designation to the Board, and the Board will not nominate for election or designate any such person as a director; provided, that, the Board may waive the application of this policy if the Board determines that the value of a particular director's contribution makes it advisable to do so. The Corporate Governance Guidelines also include a policy regarding a change of director's circumstances. In general, under this policy, any director who retires, or makes a significant change to his or her principal employment or experiences a significant change in his or her personal circumstances that may reasonably have an adverse effect on the director's service on the Board, including his or her independence or the Company's business or reputation, must offer his or her resignation to the Board. The Nominating Committee then will review the appropriateness of that director's continued service on the Board in light of the new circumstances and will make a recommendation to the Board as to whether the resignation should be accepted. Information Concerning Nominees for Election as Directors Director Independence Our Board of Directors adopted our Corporate Governance Guidelines, which contain the director independence guidelines and provide that a majority of the members of the Board must qualify as independent. Our committee charters provide that each of the Audit Committee, the Compensation Committee, the Nominating Committee and the Risk Committee must consist of directors who are independent. The Board uses the Nasdaq Stock Market (“Nasdaq”) Corporate Governance Standards (the “Standards”) and applicable SEC rules to determine independence. In each case, the Board broadly considers all relevant facts and circumstances and applies the guidelines and the Standards in determining whether directors qualify as “independent.” Our Corporate Governance Guidelines are available through the investor relations page of our internet site, http://investors.crossfirstbankshares.com, and in print free of charge to any stockholder who requests a copy. The Board reviewed the independence of all of our current directors. During this review, the Board considered transactions and relationships between each director or any member of his or her immediate family (or any entity of which a director or an immediate family member is an executive officer, general partner or significant equity holder) and the Company and its subsidiaries and affiliates. The Board also considered whether there were any transactions or relationships between directors or any member of their immediate family and members of the Company’s senior management. The purpose of this review was to determine whether any such relationships or transactions existed that were inconsistent with a determination that the director is independent. As a result of this review, the Board affirmatively determined that each of our directors are independent of the Company and its management under the Standards and applicable SEC rules, except George F. Jones, Jr. Michael J. Maddox, and David O’Toole. The Board determined Messrs. Jones, Maddox and O’Toole are not independent because they are employees of the Company or its subsidiary Bank. In determining that each of the directors other than Messrs. Jones, Maddox and O’Toole is independent, the Board considered, among other things, certain relationships, which it determined were immaterial to the directors’ independence. The Board considered that the Company and its subsidiaries in the ordinary course of business have, during the last three years, sold products and services to, and/or purchased products and services from, law firms or companies at which some of our directors were partners or officers during 2019. In each case, the amount paid to or received from these companies in each of the last three years did not exceed the greater of $200,000 or 5% of that organization’s consolidated gross revenues, and in the case of individuals $120,000, the thresholds set forth in the Standards. Board Operations Board and Committee Meetings Our Board held eight meetings during 2019. Each director attended at least 75% or more of the total number of meetings of the Board and the standing committees on which such director served that were held while the director was a member, except Ms. Grigsby. Our Board has established the following standing committees: Audit, Compensation, Nominating, and Risk. The membership and function of each committee and the number of meetings held by each committee during 2019 is described below. Proxy Statement Page 10

The committee charters are available through the investor relations page of our internet site http://investors.crossfirstbankshares.com. All members of the Audit, Compensation, Nominating, and Risk Committees satisfy the standards of independence applicable to members of such committees under applicable Nasdaq rules. In addition, the Board has determined that Mr. Rauckman and Ms. Grigsby are “audit committee financial experts” as such term is defined in Item 407(d) of Regulation S-K under the Exchange Act and are financial experts and have the financial sophistication required applicable Nasdaq rules due to their experience and background. Board Leadership Structure On August 31, 2018, the Board of Directors resolved to separate the roles of Chairman of the Board and Chief Executive Officer in recognition of the differences between the two roles. The Chief Executive Officer is responsible for setting our strategic direction and the day-to-day leadership and performance. The Chairman of the Board provides guidance to the Chief Executive Officer, sets the agenda for board meetings, presides over meetings of the full Board of Directors (including executive sessions), and facilitates communication among the independent directors and between the independent directors and the Chief Executive Officer. Our Board of Directors further believes that the separation of the duties of the Chief Executive Officer and the Chairman of the Board eliminates any inherent conflict of interest that may arise when the roles are combined. The Company's Bylaws, as well as our Corporate Governance Guidelines, provide that the office of the Chairman and the office of the CEO may be, but need not be, held by the same person. The Company has a strong independent Board, with all directors except for Messrs. Jones, O’Toole and Maddox having been determined to be independent under Nasdaq listing standards. Further, as previously noted, all standing committees of the Board are composed solely of independent directors. The Board believes that having an Independent Chairman, separate from the CEO role, is the most appropriate leadership structure at this time. Although the Board believes that this best serves the interests of the Company and its stockholders, the Board retains the flexibility to combine the roles in the future. The Board recognizes its responsibility for the establishment and maintenance of the most effective leadership structure for the Company, taking into account all relevant facts and circumstances. Pursuant to our Corporate Governance Guidelines, the Board has indicated that it will appoint a Lead Director whenever the position of Chairman is not held by an independent director. Non-Employee Director Meetings In accordance with our Corporate Governance Guidelines, the non-employee directors meet regularly in executive sessions without management present. Currently, all non-employee directors are independent. The Independent Chairman, who is independent, presides over executive and independent director sessions. Our Board met five times in executive session. Compensation Committee Interlocks and Insider Participation The following persons served on our Compensation Committee during 2019: Messrs. Brenneman, Bruce, Hansen and Humphreys. During 2019, no member of the Compensation Committee was an officer or employee or former officer of the Company or any of our subsidiaries. None of our executives served as a member of (i) the Proxy Statement Page 12

Board & Governance Matters compensation committee of another entity in which one of the executive officers of such entity served on our Compensation Committee or (ii) the compensation committee of another entity in which one of the executive officers of such entity served as a member of our Board. Board Attendance at Annual Stockholder Meeting Members of our board of directors are invited and encouraged to attend each annual meeting of stockholders. Eleven of our directors attended our 2019 Annual Meeting of Stockholders. Code of Ethics and Business Conduct The Company maintains a Code of Ethics and Business Conduct applicable to all directors, officers and employees, including senior financial officers, and provides a statement of CrossFirst’s policies for conducting business legally and ethically. The Code of Ethics and Business Conduct is available without charge through the investor relations page of our internet site, http://investors.crossfirstbankshares.com, or by writing to the attention of: CrossFirst Bankshares, Inc. 11440 Tomahawk Creek Parkway, Leawood, Kansas, 66211 Attn: General Counsel & Corporate Secretary. Any waivers of the provisions of this Code of Ethics and Business Conduct for directors or executive officers may be granted only in exceptional circumstances by the Board, or an authorized committee thereof, and will be promptly disclosed to the Company’s stockholders as may be required under the Securities and Exchange Commission ("SEC") or Nasdaq rules. Board and Committee Evaluations In order to monitor and improve its effectiveness, and to solicit and act upon feedback they receive, the Board and its committees annually engage in a formal self-evaluation process. The Nominating Committee begins the process each year by reviewing and approving the self-evaluation procedures to ensure the independence and integrity of the process. Each member of the Board is then interviewed regarding his or her board and committee service, and any findings are shared with the Independent Chairman. The Independent Chairman then reports the findings to the Nominating Committee and full Board and each standing committee to facilitate a discussion of the results. Board Role in Risk Oversight Our Board of Directors has ultimate authority and responsibility for overseeing our risk management. Our Board of Directors monitors, reviews and reacts to material enterprise risks identified by management. Our Board of Directors receives specific reports from executive management on credit, interest rate, liquidity, transactional, compliance and legal, strategic, and reputational risks and the degree of exposure to those risks. Our Board of Directors helps ensure that management is properly focused on risk by, among other things, reviewing and discussing the performance of senior management and business line leaders. Committees of our Board of Directors have responsibility for risk oversight in specific areas. The Audit Committee oversees financial, accounting and internal control risk management policies. The Compensation Committee assesses and monitors risks in our compensation program. The Risk Committee, working closely with the Chief Risk Officer, assists our Board of Directors in its oversight of the enterprise-wide risk management of the Company, including but not limited to, risks associated with credit activities, regulatory compliance, vendor management, technology/cybersecurity, investment, markets, products and operational risks. The Company’s subsidiary Bank also has a separate board. The Bank board consists of certain members of the Company’s board. Its members are Messrs. Jones, O’Toole, Maddox, Robinson, Shadwick, King, Geist, Kuykendall and Rauckman. This Bank board meets on a regular basis and its committees also take an active role in risk management. The Bank board regularly shares its materials with the Company’s board on a regular basis. Proxy Statement Page 13

Director Compensation Director Compensation Director Compensation and Role of the Compensation Committee The compensation paid to our non-employee directors further advances the interests of the Company and its stockholders by encouraging increased share ownership to promote long-term stockholder value. The Compensation Committee is responsible for reviewing the effectiveness of the non-employee director compensation program in supporting the Company’s ability to attract qualified directors and align their interests with shareholders. The Compensation Committee reviews director compensation annually and considers a variety of factors, including our financial performance, general market conditions, director compensation at comparable companies, director responsibilities, and trends in director compensation practices. Any recommendations for changes in director compensation are made to our Board. The compensation payable under our directors’ compensation program for 2019 is described below. Compensation Program Description Annual Compensation Amount* Annual Director Fees $30,000 in cash and $30,000 in restricted stock Non-Executive Chairman Fee $25,000 Audit Committee Chair $20,000 Compensation Committee Chair $20,000 Corporate Governance & Nominating Committee Chair $20,000 Risk Committee Chair $20,000 *Each director has the ability to elect to receive the cash portion of such director’s fees in restricted stock In late 2019, Meridian Compensation Partners, LLC, the Company’s compensation consultant, conducted a market review of director compensation. Meridian used the same peer group that it used for executive compensation benchmarking to provide the Board with a market review of Board compensation, which included a review of retainers, meeting fees and equity grants to directors. The Compensation Committee reviewed the data, and after consideration of the same, recommended that the Board approve the following changes to the 2020 Director Compensation Program: (1) added retainers for committee members (except chairs) as follows: $5,000 for Audit Committee members, $2,500 for Compensation, Nominating and Risk Committee members; and (2) increased non- executive chair fee to $30,000. The Board considered the recommendation and approved the changes effective after the 2020 Annual Meeting. Reimbursements Directors are reimbursed for reasonable expenses incurred in attending Board, committee and stockholder meetings, including reasonable expenses for travel, meals and lodging. Directors Deferred Fee Plan In 2018, our Board of Directors adopted a voluntary Directors’ Deferred Fee Plan (the “Directors’ Deferred Fee Plan”) that permits electing directors to receive deferred shares of our common stock in lieu of: (i) cash directors’ fees and (ii) stock directors’ fees. The payment of the deferred shares received under the Directors’ Deferred Fee Plan are deferred for tax purposes until a director’s service on our Board of Directors ends. Before any deferred shares are delivered to a participating director, the director does not have any right to vote any of his or her deferred shares nor to receive any cash dividends on the deferred shares to the extent dividends are payable on shares of our common stock. If and when we pay a cash dividend on our shares, additional deferred shares are credited to a participating director’s account. The additional shares credited have a value equal to the dividends that otherwise would have been payable to a plan account if the hypothetical shares then credited were actual shares of our common stock. All credited whole deferred shares will be settled in actual shares of our common stock and such shares will be issued to a director upon the director’s termination from service on our Board of Directors. Any fractional deferred share will be rounded up to a whole share. The plan applies only to eligible director compensation earned after that date. Proxy Statement Page 14

Executive Compensation Executive Compensation Overview As an Emerging Growth Company under the JOBS Act, we have opted to comply with the executive compensation disclosure rules applicable to “smaller reporting companies” as defined in the rules promulgated under the Securities Act. These rules permit us to limit reporting of compensation disclosure to all persons serving as our principal executive officer during our last completed fiscal year and our two other most highly compensated executive officers, which are referred to as our “named executive officers” or “NEOs.” Our named executive officers for 2019, which consist of our current principal executive officer and the two other most highly compensated executive officers, are: o George F. Jones, Jr., President and Chief Executive Officer of the Company; o W. Randall Rapp, Chief Credit Officer; and o Mike Maddox, President and Chief Executive Officer of the Bank. We compensate our named executive officers through a combination of base salary, annual cash incentives, long- term equity incentives and other benefits, including perquisites. Our Board of Directors believes the executive compensation packages that we provide to our executives, including the named executive officers, should reward performance. Each element of compensation is designed to achieve a specific purpose and to contribute to a total package that is competitive with similar packages provided by other institutions that compete for the services of individuals like our named executive officers. Compensation Program and Objectives The Company's 2019 executive compensation program and compensation decisions were based on the following principles: Pay for Performance Balanced Compensation Structure Market-Competitive Pay Opportunity Our compensation should reflect We seek to deliver a mix of fixed and Our compensation should be Company, business segment, and variable compensation that is competitive relative to our peers in individual performance. aligned with stockholder interests order to attract, motivate and retain a and the long-term interests of the talented executive team. Company and that appropriately balances risk and reward. Pay for Performance Our compensation program is grounded on a pay for performance philosophy and is designed to reward achievement of the Company's financial and strategic goals included in our business plans established before each performance cycle. In determining executive compensation, the Committee considers financial performance and strategic performance factors, risk performance, internal pay equity and individual NEO performance. The majority of our targeted compensation for our NEOs is in the form of variable compensation, a large portion of which is paid in performance shares and restricted stock units (RSUs) tied to the long-term performance of the Company and designed to be aligned with stockholder interests. Financial performance factors considered by the Committee in setting and determining executive annual and long-term compensation include the following:  Adjusted Return on Average Assets (“ROAA”)  Adjusted Earnings Per Share (“EPS”)  Adjusted Net Income Proxy Statement Page 16

Executive Compensation Practices and Policies Supporting Strong Corporate Governance and Compensation Programs We continue to maintain our disciplined approach to executive compensation with a focus on pay for performance, strong governance, risk management, and simplicity as evidenced by the following practices:  Pay for Performance: The majority of the targeted compensation for our NEOs is in the form of variable compensation linked to the long-term financial and strategic goals of the Company. Incentive compensation metrics are based on contribution margin, adjusted EPS and adjusted ROAA and NEOs’ goals are designed to be aligned to the plan.  Stockholder alignment: Our compensation program is designed to be aligned with our long-term interests and those of our stockholders with deferred long-term incentives (“LTI”) in the form of RSUs and Performance Shares linked to stock price appreciation.  Independent oversight: Our Compensation Committee includes only directors who are independent under applicable Nasdaq listing standards and the Committee is advised by an independent compensation consultant.  Incentive award limits: NEOs' incentive awards have a maximum payout cap.  Clawback of incentive compensation: Our Employee Compensation Policy and equity awards provide for clawbacks that allow us to recover shares issued pursuant to RSUs and PSUs under certain circumstances.  Risk management: We regularly evaluate the risk impact of the design of our incentive compensation program.  Balanced change in control protection: Our change in control severance policy includes a double trigger and does not provide excise tax gross-ups for any employees.  Restrictive covenants: LTI awards to NEOs are subject to non-competition and non-solicitation provisions.  Stock ownership requirements: Contractual stock ownership requirements for our NEOs. Balanced Compensation Structure The Committee determines compensation targets (sum of base salary, target Annual Cash Incentive (“AIP”) and LTI opportunities) for the NEOs at the beginning of the year, based on each executive’s role and market practice and our desired pay mix. Actual pay will vary based on Company and individual performance. Target AIP and LTI opportunities are established for, and communicated to, the NEOs at the beginning of the year or, if later, at the time of any subsequent increase in AIP or LTI opportunity. The actual year-end AIP awards paid and LTI awards made to the NEOs are determined by the Committee based on its evaluation of financial performance and other performance factors, risk performance and individual performance. The Committee also considers compensation levels of other executives in similar roles both within the Company and at industry peers before making compensation decisions. The Committee uses discretion to exercise its judgment instead of solely relying on a formulaic structure which it believes provides the right level of transparency while maintaining the flexibility necessary to pay amounts deemed appropriate for performance. The Committee has determined that a balance of the following pay components provides an effective combination of risk and reward: (At Risk) Time-based Element Base Salary Restricted Annual Incentive Performance Shares Stock Units Highlights Fixed compensation Award of Time Annual cash bonus Annual award of performance based on scope of based RSUs that opportunity based on shares that will vary and vest responsibility, impact on vest in 1/3 Company financial based on achievement of our the organization, increments over performance, primarily 3-year performance goals expertise, experience, and 3 years contribution margin, and individual performance. other performance factors, risk and individual performance.

The Company's General Counsel and its Chief Risk Officer may direct senior leaders from the Company's Human Resources, Legal, and Risk Management teams to compile and analyze information about the Company's incentive compensation practices and payment history to understand how evaluation of business risk events affect certain AIP and LTI performance measures and compensation decisions. After evaluation of the data and based on upon management’s evaluation of compensation risks, the Company’s General Counsel prepares a report of the risk assessment, which includes any recommendations for risk adjustments to incentive compensation in connection with risk events. Such report is then shared with the Committee. Peer Group For 2019 compensation decisions, the peer group consisted of the following companies: Enterprise Financial Services Horizon Bancorp, Inc. Mercantile Bank Corporation Corp Allegiance Bancshares, Inc. Stock Yards Bancorp, Inc. Veritex Holdings, Inc. Triumph Bancorp, Inc. Independent Bank Corporation 1st Source Corporation Equity Bancshares, Inc. CBTX, Inc. Meta Financial Group, Inc. First Internet Bancorp Sterling Bancorp, Inc. National Bank Holdings Corporation QCR Holdings, Inc. Market-Competitive Pay Opportunity The Committee reviewed and considered competitive market data from the following sources when approving NEO compensation: proxy data from an established peer group of companies (discussed above) and other market survey data from companies within the financial services industry. Role of the Compensation Committee The Committee is responsible for the review and approval of all aspects of the Company’s executive compensation program and makes all decisions regarding the compensation of the Company’s NEOs. Specifically, the Committee has responsibility to, among other things: Proxy Statement Page 18

Executive Compensation  Review, approve, and administer all compensation programs affecting NEOs and evaluate whether such plans are aligned with the Company’s compensation structure policies;  Annually review and approve: o Performance criteria, goals, and award vehicles used in our compensation plans for our NEOs, and o Performance of and compensation delivered to our NEOs;    Review the Company’s compensation practices to evaluate whether such practices take into account risk outcomes in making compensation determinations and do not encourage imprudent risk-taking; and   Review and approve any contracts, policies, or programs related to compensation, contractual arrangements, or severance plans affecting NEOs. As described below, the Compensation Committee consults with management with respect to the compensation of the NEOs, other than the CEO. Role of NEOs in Compensation Decisions. Our CEO, senior Company Human Resources personnel, CFO and General Counsel provide information to the Compensation Committee at their request. Examples of information that management provides the Compensation Committee includes: business strategy, financial performance, risk assessments, accounting and legal considerations. Management representatives also provide the Compensation Committee with preliminary reviews of Company and executive performance for their determination of compensation pay decisions. The CEO provides feedback and recommendations on executives’ overall contribution to Company performance and individual responsibility for business segment, functional, and/or strategic goals. For 2020 compensation decisions, the CEO provided his recommendations during the Committee's October 2019 meeting and provided his final recommendations to the Committee during the Committee's February 2020 meeting. No NEO was involved in his or her own pay recommendations or decisions and the Compensation Committee meets in executive session. The role of the Committee and its consultant are discussed below. The decisions of the Committee for 2019 performance are reflected below under "Components of Compensation." Use of Consultants The Compensation Committee has retained Meridian Compensation Partners, LLC (“Meridian”) to provide independent counsel on the design and market competitiveness of the Company’s executive compensation program. Periodically, Meridian conducts a benchmarking study utilizing a peer group. The purpose of this assessment is to provide market perspective to the Compensation Committee as it sets base salaries and incentive opportunities for the next year. In October 2018, Meridian conducted a competitive market analysis to provide guidance relating to setting 2019 compensation opportunities. The peer group was selected to represent banks of similar asset size (positioning the Company at median) with a similar business model. Applicable SEC rules require companies to assess whether the work of any compensation consultant who has played any role in determining or recommending the amount or form of executive or director compensation raises any “conflicts of interest.” If so, the company must disclose in its proxy statement the nature of any such conflict of interest and how it is being addressed. The Compensation Committee reviewed the relationships among Meridian and the Company’s trustees and executive officers in order to assess whether the work done by Meridian raised any conflicts of interest. The Compensation Committee did not identify any such conflicts of interest in its inquiry of these parties as a part of this assessment. Under its charter, the Compensation Committee also has the authority to retain, approve fees for and terminate advisors, consultants and legal counsel as it deems necessary to assist in the fulfillment of its responsibilities. Prior to engaging any such advisor, consultant or legal counsel, the Compensation Committee considers the independence assessment of such advisor pursuant to applicable Nasdaq and SEC rules, but the committee retains discretion to engage any such advisor, without regard to its independence, after considering the findings in such assessment. Components of Compensation Base Salary We provide each of our current named executive officers with a competitive fixed annual base salary. The base salaries for our named executive officers are reviewed annually by the Compensation Committee by taking into account the results achieved by each executive, his or her future potential, scope of responsibilities and experience, and competitive pay practices. For the fiscal year ended December 31, 2019, our named executive officers received annual base salaries as follows: (i) $463,500 for Mr. Jones; (ii) $350,000 for Mr. Rapp; and (iii) $360,500 for Mr. Maddox. Proxy Statement Page 19

Executive Compensation Annual Incentive Program Each of our current named executive officers are entitled to participate in our Annual Incentive Program, which provides for an annual cash award to be determined by the Compensation Committee based on attainment of certain performance criteria. Our Annual Incentive Program is designed to motivate and reward superior performance, attract and retain talent, encourage teamwork and collaboration, and ensure incentives are appropriately risk balanced. Pursuant to the terms of the Annual Incentive Program, participants are awarded a cash incentive based on attainment of Company and individual performance goals during each calendar year. Award opportunities and performance goals are approved by the Compensation Committee at the beginning of each year. For 2019, the Company must have achieved at least a threshold level of net income for any awards to be paid and awards are subject to reduction for certain items. Each participant under the Annual Incentive Program is assigned an incentive award target with threshold, target, and stretch performance levels of achievement. If actual performance falls below the threshold level of performance there would be no award payout. Performance at the threshold, target and stretch performance levels would result in payments equal to 50%, 100%, and 150% of the targeted incentive opportunity. Payouts for performance between the threshold and target or target and stretch performance levels would be interpolated to reward incremental improvement. Payouts may be adjusted by the Compensation Committee based upon its determination of whether the participant met his or her individual performance goals. For 2019, the threshold achievement level net income number was $30,075,532, the Company’s actual performance was $28,473,000. Because the Company did not achieve the threshold performance level of net income, no Annual Incentive Awards were paid to Messrs. Jones and Maddox. In connection with negotiations for him to join CrossFirst, Mr. Rapp received a guaranteed Annual Incentive Award of $175,000 for 2019 only and a $30,000 signing bonus. Equity Awards We grant equity awards to our employees, including our named executive officers, in order to drive achievement of our long-term financial objectives and value creation for stockholders, provide rewards for our overall performance and tie value to our stock price performance, align our employees’ interests with those of our stockholders and promote equity ownership among our employees. A summary of our equity compensation plans is provided below under “Equity Based Plans.” For 2019, we granted the long-term equity incentives described below to our named executive officers. In 2019, we granted time-based restricted stock units and performance shares to Messrs. Jones and Maddox as follows: Name Grant Date No. of RSUs Performance Shares George F. Jones, Jr. 2/27/19 7,476 7,476 Mike Maddox 2/27/19 4,652 4,652 The above time-based restricted stock unit awards granted to Messrs. Jones and Maddox in February 2019 will vest annually in one-third increments. Mr. Rapp did not receive annual awards as he was not an executive with CrossFirst at the time of grant. The performance shares support the achievement of our long-term strategic and financial objectives and create an incentive to deliver stockholder value. The award of performance shares granted are contingent upon 3-year performance goals established for EPS and ROA, which are equally weighted. The performance shares granted in February 2019 to Messrs. Jones and Maddox will cliff vest in 2022 based on certification of performance, and can vary between 50% of target for threshold performance and 150% of target for performance at maximum. Linear interpolation will be used if achievement is between values, and the entire award will be forfeited if threshold performance is not met on both measures. Other Awards The Compensation Committee awarded Messrs. Jones and Maddox a bonus in connection of their work on the initial public offering of $97,335 and $63,088 respectively. The Committee also evaluated the results under our Annual Incentive Plan, including net income that was modestly below the plan threshold. Proxy Statement Page 20

Executive Compensation The Committee recognized that certain unanticipated external factors contributed to these results, including changes that impacted collectability of a loan. The Committee also considered key achievements of Mr. Jones and Mr. Maddox during 2019, including adjusting our business model to increase profitability. Based on this assessment, the Committee determined to award discretionary awards to Mr. Jones and Mr. Maddox at the threshold level under the plan ($139,050 and $90,125 respectively). Mr. Rapp received an award of 45,162 Stock Settled Appreciation Rights as negotiated in connection with his joining CrossFirst. Mr. Rapp also received a $20,000 spot bonus during 2019. Other Benefits and Perquisites The named executive officers participate in the Company’s broad-based employee welfare benefit plans, such as medical, dental, vision, supplemental disability and term life insurance. The named executive officers also participate in the Company’s 401(k) plan. The Company makes safe harbor matching contributions of 100% of employees’ salary deferral amounts on the first 1% of employees’ compensation (excluding any expense repayments, fringe benefits, moving expenses, deferred compensation and welfare benefits) plus 50% of employees’ salary deferral amounts on over 1% of employees’ compensation but not over 6% of employees’ compensation. The named executive officers are provided the same welfare benefits and 401(k) plan matching contributions and participate in the cost at the same rate as all other employees. We provide our named executive officers with certain perquisites that we believe are reasonable and consistent with our overall compensation program to better enable us to attract and retain superior employees for key positions. These perquisites include in some cases mobile communications (including iPhones, iPads and a data plan), the use of an automobile or an automobile allowance, and country club memberships, as discussed in more detail in connection with the description of the employment agreements of our named executive officers below. The Compensation Committee periodically reviews the levels of perquisites and other personal benefits provided to named executive officers. Based on these reviews, perquisites may be adjusted on an individual basis. Employment Agreements Employment Agreement with George F. Jones, Jr. On May 1, 2018, we entered into an amended employment agreement with Mr. Jones pursuant to which he serves as the Chief Executive Officer of the Company for a term continuing through December 31, 2021 and as a Director of the Company.

Furthermore, in the employment agreement the Company agrees that Mr. Jones will be eligible for retirement under the 2018 Equity Incentive Plan as of April 29, 2021, and that if Mr. Jones retires on December 31, 2021, any SARs granted to him on or before December 31, 2020 shall be fully vested.

The equity awards granted in 2019 shall become fully vested no later than December 31, 2021.

Change in Control In the event the Company experiences a change in control, all of the time-vesting outstanding equity awards listed above will become fully vested as of the date of the change in control, while any performance-vesting equity award will vest at a target level of goal achievement as of the date of the change in control.

The named executive officer or his estate may only exercise a stock appreciation right which vests due to the named executive officer’s termination of employment due to death or disability within the 12- month period following the date of the named executive officer’s termination of employment due to death or disability. Termination of Employment due to Qualified Retirement In the event a named executive officer experiences a termination of employment due to qualified retirement, a pro rata portion of the named executive officer’s time-based vesting restricted stock units will vest upon the named executive officer’s retirement. For named executive officers, any stock appreciation rights with a date of grant preceding the named executive officer’s termination of employment due to qualified retirement by 12 months or more shall become vested upon the named executive officer’s termination of employment due to qualified retirement. Such Proxy Statement Page 27

Executive Compensation stock appreciation rights may only be exercised during the 12-month period following the named executive officer’s termination of employment due to qualified retirement. An executive officer must have attained the age of 65, be in good standing with the Company and have been employed with the Company for no less than 5 years to be eligible for qualified retirement. As of December 31, 2019 no named executive officer was eligible for a qualified retirement. Proxy Statement Page 28

Audit Matters Audit Matters PROPOSAL 2 Ratification of Appointment of Independent Registered Public Accounting Firm The Audit Committee has the sole authority and responsibility to appoint, compensate, retain, oversee, evaluate and, when appropriate, replace the independent public accounting firm. Each year the Audit Committee evaluates the qualifications and performance of the independent public accounting firm and considers, as appropriate, the rotation of the independent audit firm. Based on this evaluation, the Board of Directors and the Audit Committee recommend that you approve the ratification of the appointment of BKD LLP (“BKD”) to serve as our independent registered public accounting firm for the 2020 year. The Board of Directors and the Audit Committee believe the continued retention of BKD is in the best interest of the Company and its stockholders. BKD has served as the independent registered public accounting firm for the Company since 2009. Consistent with the regulations adopted pursuant to the Sarbanes-Oxley Act of 2002 and the Audit Committee’s Charter, the lead audit partner having primary responsibility for the audit and the concurring audit partner are rotated every five years. The current lead BKD audit partner was designated commencing with the 2017 audit. A representative of BKD will be present at the Annual Meeting, will have the opportunity to make a statement, if desired, and will be available to respond to appropriate questions. The Board of Directors recommends a vote “FOR” the ratification of BKD’s appointment as our independent registered public accounting firm for the 2020 year. Proxies solicited by the Board will be voted “FOR” this ratification unless otherwise instructed. Independent Registered Public Accounting Firm Fees The Audit Committee pre-approves all audit and non-audit fees associated with the Company’s retention of BKD. The following table summarizes the aggregate fees (including related expenses) for professional services provided by BKD related to 2019 and 2018 (amounts in thousands). 2019 2018 Audit Fees (1) 639,434 251,011 Audit-Related Fees (2) 87,812 85,488 Tax Fees (3) 132,503 146,957 All Other Fees (4) - - Total 859,749 483,456 (1) Audit fees include financial statement audits, review of interim financial statements, audit committee meetings, accounting and auditing consultations, comfort letters and consents.

Audit Matters Policy Regarding Pre-Approval of Independent Registered Public Accounting Firm Services In order to assure the continued independence of our independent registered public accounting firm, the Audit Committee has adopted a policy requiring pre-approval of audit and non-audit services performed by our independent registered public accounting firm. Under that policy, the Audit Committee pre-approves a list of audit, audit-related and permitted non-audit services that may be provided by the independent registered public accounting firm without obtaining specific pre-approval from the Audit Committee. In addition, the Audit Committee sets pre- approved fee levels for the pre-approved services. Any type of service that is not included on the list of pre-approved services or that exceeds pre-approved fee levels must be specifically pre-approved by the Audit Committee. The Audit Committee has delegated to the Chair of the Audit Committee the authority to pre-approve any audit or permitted non-audit service to be performed by the independent registered public accounting firm, provided that such approvals are presented to the full Audit Committee at the next scheduled meeting and that estimated fees for such services are not in excess of certain limits. The Audit Committee reviews its pre-approval policy annually for purposes of assuring its continued appropriateness and compliance with applicable law and listing standards. Audit Committee Report The Company’s Audit Committee oversees and reports to the board of directors regarding accounting and financial reporting processes, the audits of the financial statements, the qualifications and independence of the independent registered public accounting firm engaged to provide independent audits and related services, and the performance of the internal audit function and independent registered public accounting firm; and also performs the other duties of the committee specified by federal securities laws and regulations, the Federal Deposit Insurance Act and related regulations, the listing standards of the Nasdaq, and its charter. The committee (1) has reviewed and discussed the audited financial statements included in the Company’s 2019 Annual Report on Form 10-K with management; (2) has discussed with our independent registered public accounting firm all matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (‘PCAOB”) and the rules of the SEC and Nasdaq); and (3) has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCABOB regarding the independent accountant’s communications with the committee concerning independence and has discussed independence with the independent registered public accounting firm. Based upon this review, discussion, disclosures, and materials described in (1) through (3), the committee recommended to the board of directors that the audited financial statements be included in the 2019 Annual Report on Form 10-K. The committee also has considered whether the amount and nature of non-audit services rendered by the independent accountant are consistent with its independence. Submitted by the Audit Committee of the Board of Directors: Kevin Rauckman (Chair) Steven W. Caple Jennifer Grigsby James Kuykendall Steve Swinson The information contained in the Audit Committee Report shall not be deemed to be “soliciting material” or to be “filed” with the Securities and Exchange Commission, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that we specifically incorporate it by reference in such filing.

Related Person Transactions Policies and Procedures Regarding Related Person Transactions Transactions by us or the Bank with related persons are subject to regulatory requirements and restrictions. These requirements and restrictions include the Affiliates Act and the Federal Reserve’s Regulation W (which governs 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 stockholders). We have adopted policies to comply with these regulatory requirements and restrictions. In addition, our Board of Directors has adopted a written policy governing the approval of related person transactions that complies with all applicable requirements of the SEC and Nasdaq concerning related person transactions. Related person transactions are transactions in which we are a participant, the amount involved exceeds $120,000 and a related person has or will have a direct or indirect material interest. Related persons of the Company include directors (including nominees for election as directors), executive officers, beneficial holders of more than 5% of our capital stock and the immediate family members of these persons. Any related person transaction proposed to be entered into by the Company, or any of its subsidiaries, must be reported to the Company’s General Counsel and shall be reviewed and approved or ratified by the Audit Committee in accordance with the terms of the policy. In determining whether to approve a related person transaction, that committee will consider, among other factors, the approximate dollar value of the amount of the related person’s interest in the transaction, the nature of the Company’s participation in the transaction, whether the transaction was undertaken in the ordinary course of business of the Company, whether the transaction with the related person is on terms no less favorable to the Company than terms that could have been reached with an unrelated third party and the purpose of and the potential benefits to the Company of the transaction. In addition to the compensation arrangements with directors and executive officers described in “Director Compensation” and “Executive Compensation” above, the following is a description of each transaction since January 1, 2019, and each proposed transaction in which:  we have been or are to be a participant;  the amount involved exceeds or will exceed $120,000 ; and  any of our directors, executive officers or beneficial holders of more than 5% of our common stock, or any immediate family member of or person sharing the household with any of these individuals (other than tenants or employees), had or will have a direct or indirect material interest. Transactions During fiscal year 2019: (i) George Bruce and his affiliates acquired 10,000 shares of common stock for $5.00 per share through the exercise of warrants; (ii) Jay Shadwick acquired 13,500 shares of common stock for $5.00 per share through the exercise of warrants; (iii) Mike Maddox acquired 40,000 shares of common stock for $5.00 per share through the exercise of warrants; and (iv) Michael Robinson acquired 13,500 shares of common stock for $5.00 per share through the exercise of warrants. On December 18, 2018, we provided notice to all holders of our Series A Preferred Shares of our intent to redeem all outstanding Series A Preferred Shares on January 30, 2019 at a redemption price of $25.00 per share. Upon redemption, we paid holders of Series A Preferred Shares the redemption price per share of the Series A Preferred Shares and the holders’ pro rata share of a 30-day dividend for January 2019 in the aggregate amount of $175.0 thousand. Affiliates of the following directors held Series A Preferred Shares, and such affiliates received such redemption price and the pro rata share of such dividend: (i) George Bruce (2,000 shares); (ii) Ron Geist (20,000 shares); (iii) Jennifer Grigsby (10,000 shares); and (iv) Lance Humphreys (2,000 shares). Certain of our officers, directors and principal stockholders, as well as their immediate family members and affiliates, are clients of, or have or have had transactions with us or the Bank in the ordinary course of business. These transactions include deposits, loans and other financial services related transactions. Related person transactions are made in the ordinary course of business, on substantially the same terms, including interest rates and collateral (where applicable), as those prevailing at the time for comparable transactions with persons not related to us, and do not involve more than normal risk of collectability or present other features unfavorable to us. Any loans we originate with officers, directors and principal stockholders, as well as their immediate family members and affiliates, are approved by our Board of Directors in accordance with the Bank’s regulatory requirements. As of March 20, 2020, our officers, directors and principal stockholders as well as their immediate families and affiliated companies, as a group, were indebted directly and indirectly to us approximately $17 million, while deposits Proxy Statement Page 34

Related Person Transactions from this group totaled approximately $55 million as of such date. As of March 20, 2020, no related party loans were categorized as non-accrual, past due, restructured or potential problem loans. We expect to continue to enter into transactions in the ordinary course of business on similar terms with our officers, directors and principal stockholders, as well as their immediate family members and affiliates. We have engaged Crews & Associates, Inc., an SEC-registered securities dealer, to execute certain trades of municipal bonds on our behalf. Crews & Associates, Inc. is a wholly-owned subsidiary of First Security Bancorp, a beneficial holder of more than 5% of our capital stock. In connection with these trades, we paid Crews & Associates, Inc. aggregate commissions of approximately $100 thousand in fiscal year 2019, $86.5 thousand in fiscal year 2018, and $313.5 thousand in fiscal year 2017. In addition, from time to time, we sell loan participations to, purchase loan participations from and participate in syndicated loans, shared national credits and loan participations with, First Security Bank, a subsidiary of First Security Bancorp. These transactions are conducted in the ordinary course of business, with terms and conditions comparable to those applicable to entities that are not related persons.
