&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**PROPOSAL 1.** <br>**<u>Election of Directors</u>.** <br>

The Company's Bylaws provide that the number of directors of the Company shall not be less than 5 nor greater than 15. The Board currently consists of 13 members. The Board has considered and nominated all of the current directors for election at the Annual Meeting, except for Michael J. Gerdin. On February 6, 2023, Mr. Gerdin informed the Company that he will not stand for re-election to the Company Board at the Company's 2023 Annual Meeting of stockholders, scheduled to be held on April 27, 2023. Mr. Gerdin has been a member of the Board since 2013 and will continue to serve as a member of the Board until the 2023 Annual Meeting. Mr. Gerdin also serves as a member of the Compensation Committee. Mr. Gerdin's decision not to stand for re-election to the Board was not a result of any disagreement with the Company pertaining to the Company's operations, policies or practices. As such, at its February 22, 2023 meeting, the Company's Board approved reducing the size of the Board from 13 to 12, effective immediately prior to the Annual Meeting. As a result, proxies cannot be voted for more than 12 nominees.

| | | | |
|:---|:---|:---|:---|
| 83% <br>Independent Directors | 64<br>Average Age | 7 years <br>Average Tenure | 25% <br>Female Representation |

---

The term for directors is until the next annual meeting of stockholders and until their successors are elected and qualified or until their earlier resignation, removal from office, death or incapacitation.

If any nominee or nominees become unavailable for election, it is intended that the size of the Board will be reduced accordingly, provided that the number of nominees shall not be less than five. Any stockholder has the option to withhold authority to vote for any or all nominees. Votes withheld from any nominee will have no effect on the election of directors if the number of nominees is not greater than the number of directors to be elected due to the fact that such elections are by a plurality of the votes cast.

---

| | |
|:---|:---|
| ✔ | **The Board recommends a vote "FOR" each of the nominees listed in the table below. Properly executed proxies will be voted "FOR" the election of the listed individuals, unless contrary instructions are given.** |

---

Information concerning the nominees, including their ages, year first elected as a director of the Company, principal occupation, current assignments on Company committees and description of experience are set forth below. Unless otherwise noted, the nominees have been employed in their principal occupation with the same organization for at least the last five years. All the nominees are currently serving as directors of the Company and as directors of the Company's wholly-owned subsidiary, West Bank.

As noted above, with the exception of Mr. Milligan, who is a director of United Fire Group, Inc., Mr. Noyce, who is a director of United Fire Group, Inc., and Dr. Vaughan, who is a director of Verisk Analytics, Inc. and American International Group, Inc. and was a director of Validus Holdings, Ltd. until July 2018, none of the other above nominees holds a directorship in any other company with a class of securities registered pursuant to Section 12 or subject to Section 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or registered as an investment company under the Investment Company Act of 1940. No other directorships held by nominees in the past five years require disclosure.

None of the nominees for director or executive officers of the Company has any family relationship with any other nominees or with any executive officers of the Company. There are no arrangements or understandings between any of the nominees and any other person pursuant to which he or she was selected as a nominee.

*Board Diversity with Respect to Gender, Ethnicity and Areas of Expertise*

The chart below summarizes the types of knowledge, skills and experiences each of our director nominees possesses that were most relevant to the decision to nominate him or her to serve on the Board. The absence of a mark does not mean the director does not possess that qualification or skill; rather, a mark indicates a specific area of focus or expertise on which the Board relies most heavily. Each director's biography included previously in this proxy statement describes these qualifications and relevant experience in more detail.

On August 6, 2021, the SEC approved amendments to the Listing Rules of the Nasdaq Stock Market ("Nasdaq") related to board diversity. New Listing Rule 5605(f) (the "Diverse Board Representation Rule") requires each Nasdaq-listed company, subject to certain exceptions, (1) to have at least one director who self-identifies as female and (2) to have at least one director who self-identifies as Black or African American, Hispanic or Latinx, Asian, Native American or Alaska Native, Native Hawaiian or Pacific Islander, two or more races or ethnicities, or as LGBTQ+ or (3) to explain why the company does not have at least two directors on its board who self-identify in the categories listed above. In addition, new Listing Rule 5606 (the "Board Diversity Disclosure Rule") requires each Nasdaq-listed company, subject to certain exceptions, to provide statistical information about the company's board of directors, in a uniform format, related to each director's self-identified gender, race and self-identification as LGBTQ+.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 9

Although we are not required to fully comply with the Diverse Board Representation Rule until 2025, we believe we will meet the requirements of that rule assuming the director nominees named in this proxy statement are elected and remain on the Board going forward, based on the self-identified characteristics of the director nominees. Following the 2023 Annual Meeting, the Board will have 25 percent female representation, including a female as the chair of the Nominating and Corporate Governance Committee. We believe that over the next several years, as directors attain the age of 73 years and no longer stand for reelection, the female representation percentage on the Board will increase. In the matrix below, we have provided the statistical information required by the Diverse Board Representation Rule as of December 31, 2022.

**GOVERNANCE AND BOARD OF DIRECTORS**

**General** 

Generally, the Board oversees our business and monitors the performance of our executive officers and management. In accordance with our corporate governance procedures, the Board does not involve itself in the day-to-day operations of the Company, which are monitored by our executive officers and management. Our directors fulfill their duties and responsibilities by attending regular meetings of the full Board, which are scheduled for five times per year; special meetings which are held from time to time as necessary; strategic planning meetings which are held jointly with West Bank semi-annually; and through committee membership, which is discussed below. Our directors also discuss business and other matters with our key executives and our principal external advisors, such as our legal counsel, auditors and other consultants.

The Board currently has 13 directors and will have 12 directors after the Annual Meeting if all nominees set forth in this proxy statement are elected. The Board has determined that the following 10 current directors are "independent" as defined by the Nasdaq Listing Rule 5605(a)(2) and Item 407 of Regulation S-K: Donovan, Elming, Gaer, McMurray, Milligan, Noyce, Parson, Schuler, Vaughan and Worth. The Board has further determined that the independent directors do not have other relationships with the Company that prevent them from making objective, independent decisions. David D. Nelson is an executive officer of the Company and is not considered "independent." Douglas R. Gulling, as a retired executive officer of the Company, and current non-executive employee of West Bank, is also not considered "independent."

The Board held five regularly scheduled meetings and one organizational meeting in 2022. In addition, the Company's Board and West Bank's Board held two combined meetings for the purpose of strategic planning. All directors attended at least 75 percent of the Board meetings and the meetings of any committees on which the director serves. Board members are encouraged to attend the annual meeting of stockholders, and all Board members who were directors at such time attended the 2022 annual meeting of stockholders.

*Other Committees*

Additional committees of the West Bank Board of Directors are described below. Although none of these committees have a charter, there are West Bank policies that describe oversight and responsibility of these areas.

**Trust Committee.** The Trust Committee regularly reviews the trust activities of West Bank. The committee meets four times per year and three independent West Bank directors are on the committee.

**Directors Loan Committee ("DLC").** The DLC monitors lending activities by reviewing information critical to prudent oversight. The committee meets four times per year and four independent West Bank directors are on the committee.

**Code of Ethics**

We have a Code of Conduct in place that applies to all of our directors, officers and employees. The Code of Conduct sets forth the standard of ethics that we expect all of our directors, officers and employees to follow, including our Chief Executive Officer and Chief Financial Officer. The Code of Conduct may be viewed on the Company's website (www.westbankstrong.com) under Investor Relations — Overview — Corporate Governance. We intend to satisfy the disclosure requirements under Item 5.05 of Form 8-K regarding any amendment to or waiver of the Code of Conduct with respect to our Chief Executive Officer and Chief Financial Officer, and persons performing similar functions, by posting such information on our website. The Audit Committee reviews the Code of Conduct annually and reviewed it in 2022 and recommended no changes from the previous year to the Board.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 14

**Environmental, Social and Governance Efforts**

As investor interest in environmental, social and governance ("ESG") matters grows, the Company is responding by increasing communication of such matters in its disclosures. The Company has always been committed to maintaining the highest standards of business conduct and corporate governance, which we believe are essential to running our business effectively, serving our customers and communities, creating long-term value for our stockholders and maintaining our integrity in the marketplace. We monitor developments in the ESG area and review our policies, procedures and business practices in light of such developments. We continue to develop responses to these evolving expectations.

The Board is committed to overseeing our social responsibility efforts. While ESG matters fall under the purview of each of the Board committees as it relates to their individual oversight responsibilities, in 2022, the Nominating and Corporate Governance Committee undertook formal responsibility for providing oversight of the Company's commitment to ESG matters, including providing overall strategic direction on corporate responsibility and reporting. Setting the tone at the top with our Board and executive management, our Board and its committees have a key role in the oversight of our culture by holding executive management accountable for maintaining high ethical, legal and moral standards.

We recognize that understanding our efforts to improve ESG practices is increasingly important to our stockholders, customers and employees and have included some highlights below to share our ongoing commitments in these areas.

*Financial Inclusion*

West Bank has received the highest available rating, "Outstanding," during its most recent Community Reinvestment Act ("CRA") examination by the Federal Deposit Insurance Corporation ("FDIC"). The regulatory examination reviews how we meet the credit needs of our communities, including low and moderate income neighborhoods, CRA qualified lending, corporate giving and investing and employee volunteering. West Bank's community development lending to developers, nonprofit entities and municipalities benefits communities through services to individuals, job creation, stabilization, economic development and affordable housing. West Bank has a lending and deposit portfolio that supports its nonprofit customers in their mission-driven work to meet community needs.

Since 2009, West Bank has made investments in low-income housing tax credit funds through the Midwest Housing Equity Group totaling over $10.4 million. Midwest Housing Equity Group is a nonprofit tax credit syndicator, creating affordable housing units in the central United States, including Iowa and Minnesota. West Bank has also invested in and funded loans related to a new markets tax credit project totaling approximately $28.9 million. Our involvement assisted a local nonprofit community development corporation to participate in commercial redevelopment activities in one of our primary markets.

West Bank is an SBA Preferred Lender under the federal government's Small Business Administration program. As a SBA Preferred Lender, we were able to participate in the Paycheck Protection Program ("PPP"), which was essential to support businesses in our markets during the COVID-19 pandemic. In 2020 and 2021, we processed nearly 1,500 PPP loans, providing community businesses with more than $300 million in PPP assistance.

West Bank provides financial literacy opportunities through its "Bank Notes" blog and in-person training sessions coordinated with various organizations, including Junior Achievement of Central Iowa's personal finance simulation and the Jordan Scholars program, which provides high school juniors with annual introduction to personal financial responsibility and careers in banking.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 15

*Human Capital Management*

We believe that diversity encourages innovation and inclusion, and our team's differences give us a competitive advantage. Our goal is to foster a culture in which those differences are valued and respected. Our team is made up of 173 full-time employees and 9 part-time employees. We are proud of our culturally and gender diverse workforce, with approximately 18 percent identifying as persons of color and approximately 55 percent as women. Our approach also promotes longevity in our workforce. The average tenure of our employees is over nine years. 72 employees (40 percent) have been with West Bank for over ten years and 42 employees (23 percent) have been with West Bank for over 15 years. Non-teller turnover was approximately 11 percent in 2022.

We conduct periodic company-wide employee engagement surveys to assess employee satisfaction and engagement. Our most recent survey was conducted in 2022, which provided us with valuable feedback regarding West Bank's current culture and employee satisfaction and engagement. Results of the survey, including the valuable employee comments, were reviewed by the executive team and management. Strategies were developed to address topics of noted recurrence, particularly in the areas of communication, transparency, and management openness to staff initiatives and suggestions. Positive comments concerning relationship building, customer service, and commitment to the community demonstrated our outstanding team members are dedicated to company values and aligned with company leadership.

We have adopted a Social Responsibility Statement that includes a written Diversity, Equity and Inclusion statement as well as a Human Rights Policy Statement that apply to all directors, officers and employees. These statements are available on our website at www.westbankstrong.com under Investor Relations/Overview/Governance documents.

*Environmental Sustainability*

The Board carefully considers corporate social responsibility when it works with management to determine the Company's strategic priorities and plans to achieve such priorities. We strive to be a good corporate citizen by conducting business in an environmentally responsible manner, by operating as an employer that is committed to our vibrant and diverse workforce and by maintaining strong ties to the communities in which our customers live, work and do business.

We have adopted an Environmental Policy Statement, which can be found on our website at www.westbankstrong.com under Investor Relations/Overview/Governance documents.

*Strengthening Communities* 

In 2022, sponsorships, donations and grants of more than $735,000 were facilitated through West Bank and the West Bancorporation Foundation, Inc. (the "Foundation") to more than 225 community organizations. The Foundation is the charitable foundation affiliate of the Company. We serve the communities in which we operate through economic development activities, charitable giving and volunteerism by our employees. The Foundation awards grants to organizations focused on human services, arts and culture, and education.

We encourage and support volunteer efforts of our employees who volunteer, serve on boards and provide educational and networking opportunities. In 2022, our employees volunteered over 7,000 hours of community service. This commitment and investment in the communities we serve are foundational to our success.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 16

**Board Leadership Structure**

The Board believes that having a non-chief executive officer director serve as Chair of the Board is in the best interests of stockholders by providing an effective channel for the Board to express its views on management and allows the CEO to focus on leading the Company and the Board Chair to focus on leading the Board, monitoring corporate governance and any stockholder issues. The Board currently intends to maintain the leadership structure of having a non-chief executive officer as Chair. The Board and its Nominating and Corporate Governance Committee believe that this structure will continue to be useful in providing consistent oversight and strategic direction to the Company. The Board expects Mr. Nelson to take the lead in developing strategic plans, providing day-to-day leadership and managing the performance of the Company. The Board expects the Chair to lead the Board meetings, participate in committee meetings and advise West Bank leadership. The Board intends to periodically review its leadership structure and make changes as dictated by the circumstances and the best interests of the stockholders.

**Nominating and Corporate Governance Committee Report**

During 2022, the Nominating and Corporate Governance Committee reviewed the composition of the existing Board, giving specific attention to the questions of the desirable size of the Board and how many insiders should be on the Board. The Board has a policy that no Board member should be nominated for election to the Board who has attained or will attain the age of 73 years on or before the date of the forthcoming annual stockholders' meeting and election of directors. The Nominating and Corporate Governance Committee decided that it was in the best interests of the stockholders to continue the model of having only one current member of management, the Chief Executive Officer, on the Board in order to clearly differentiate the roles of the Board and management. We anticipate that the Board will add the position of Vice-Chair in 2023.

The Nominating and Corporate Governance Committee also evaluated the qualifications and performance of each of the current members of the Board. In its evaluation, the Nominating and Corporate Governance Committee compared each of the current directors to the qualifications and characteristics of a director set forth in the Nominating and Corporate Governance Committee's charter. The Nominating and Corporate Governance Committee then polled each director eligible to stand for re-election to determine his or her willingness to stand for re-election and determined that each director is willing to continue service, except for Michael J. Gerdin who informed the Company on February 6, 2023 that he will not stand for re-election to the Company's Board of Directors. The Nominating and Corporate Governance Committee did not receive any stockholder recommendations for director nominees for the Annual Meeting. No third party was retained, in any capacity, to provide assistance in either identifying or evaluating potential director nominees for the Annual Meeting.

Based on the foregoing, the Nominating and Corporate Governance Committee recommended to the Board that Patrick J. Donovan, Lisa J. Elming, Steven K. Gaer, Douglas R. Gulling, Sean P. McMurray, George D. Milligan, David D. Nelson, James W. Noyce, Rosemary Parson, Steven T. Schuler, Therese M. Vaughan and Philip Jason Worth should be nominated for re-election to the Board at the Annual Meeting. The Board accepted these recommendations.

During 2022, the Nominating and Corporate Governance Committee reviewed its charter and recommended changes to the Board.

The undersigned members of the Nominating and Corporate Governance Committee have submitted this report.

Therese M. Vaughan, Chair

*Stockholder Engagement*

We actively engage with our stockholders on an annual basis to solicit feedback on our executive compensation program. Although over 97 percent of our stockholder votes were in favor of our executive compensation program for 2021 at our 2022 annual meeting, the Company has continued this outreach.

In 2022, we reached out to the Company's largest institutional stockholders which own or control approximately 29 percent of our outstanding shares. We had conversations with three institutions and an additional institution responded but stated that a conversation was not needed at this time.

A group consisting of a combination of some or all of the Chair of the Board, Chair of the Compensation Committee, a member of the Compensation Committee, Chair of the Nominating and Governance Committee and the West Bank Director of Human Resources participated in the discussions with the responding institutional stockholders. The Company representatives explained our compensation philosophy, and representatives of the institutional stockholders shared their views of our executive compensation program, and director compensation. The stockholders also discussed governance, risk management and sustainability matters and Company performance. The Company found the feedback offered during the outreach effort constructive and insightful, providing us with an important perspective on how to enhance our corporate disclosures.

*Overview and Objectives of Our Executive Compensation Programs*

The Company and West Bank share an executive management team. The members of the executive management team, consisting of our NEOs, are compensated by West Bank rather than the Company. Compensation of our NEOs is determined by the Company's Compensation Committee based on their performance and roles for both the Company and West Bank.

The goal of our compensation program is to create superior long-term value for our stockholders by attracting, motivating and retaining outstanding employees who serve our customers while generating financial performance that is consistently better than that of our peers. Accordingly, our compensation program for executives is guided by our business needs and challenges in creating stockholder value. To support the achievement of our business strategies and goals, we strive to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pay for performance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Align executives' financial interests with those of our stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Support the Company's and West Bank's values, strategy and development of employees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Foster a team approach among top executives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Attract and retain leaders capable of delivering strong business results;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provide competitive cash and total compensation opportunities and benefits;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Balance the mix of short-term and long-term incentives; and&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adhere to the highest legal and ethical standards.

Our executive compensation program is designed to attract, retain and motivate qualified and talented executives to achieve our business goals and to reward them for strong short- and long-term performance. In particular, our Compensation Committee is mindful that our "pay-for-performance" philosophy must align the interests of our executives with those of our stockholders in order to drive long-term, sustainable stockholder value growth. A significant amount of NEO compensation is considered at-risk, made up of annual cash and long-term equity incentive opportunities. The primary elements of our executive compensation program in 2022 consisted of base salary, annual cash incentive opportunities and long-term equity opportunities. The purpose and key features of each element are described below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 26

**Base Salary**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Base salaries are set to be competitive within our industry and are important in attracting talented executives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Base salaries are adjusted annually, effective January 1, but can be adjusted mid-year when there are material changes, such as a change in an executive officer's position, responsibilities, demonstrated performance, or relevant market data.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Base salaries for our NEOs are as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Name** | **Base Salary** <br>**2021** | **Base Salary** <br>**2022** | **Percent** <br>**Change** <br>**2022** |
| David D. Nelson | $485000 | $514000 | 6.0% |
| Jane M. Funk<sup>(1)</sup> | N/A | 300000 | N/A |
| Harlee N. Olafson | 330000 | 350000 | 6.1% |
| Brad L. Winterbottom | 330000 | 350000 | 6.1% |
| Bradley P. Peters | 275000 | 300000 | 9.1% |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Ms. Funk first became an NEO of the Company effective January 1, 2022 with her promotion to CFO.

**Annual Cash Incentive Opportunities** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Annual cash incentive opportunities are intended to motivate and reward executives for the achievement of certain financial goals in comparison to internal and external standards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Annual cash incentive opportunities are based on a percentage of base salary and that percentage is based on: (1) the Company's net profit; and (2) the Company's performance relative to our peer group based on return on average equity, efficiency ratio and total nonperforming assets ratio, equally weighted, according to the following schedule. The performance targets, peer rankings and percent of salaries remains the same as the prior year.

---

| | | |
|:---|:---|:---|
| **Performance** | **Peer Rating** | **Percent of Salary** |
| Maximum | At/above 75<sup>th</sup> percentile | 60% |
| Target | 50<sup>th</sup> percentile | 40% |
| Threshold | 25<sup>th</sup> percentile | 20% |
|  | Below 25<sup>th</sup> percentile | 0% |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If our ranking in the peer group falls between threshold and maximum level performance, our NEOs will be eligible for a proportional cash bonus based upon linear interpolation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The nonperforming assets ratio performance metric is measured by comparing the average of the four fiscal quarter-ending ratios of the Company to the average of the four fiscal quarter-ending ratios of the peer group.

**Long-Term Equity Incentive Opportunities** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Long-term equity awards incentivize executives to deliver long-term value, while also providing a retention vehicle for our executives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 50 percent of the NEO's restricted stock unit ("RSU") awards are subject to performance-based vesting and 50 percent are subject to time-based vesting. Following the date of vesting, 50 percent of the covered shares will be subject to a three-year holding period requirement. The Compensation Committee expects future awards to have a similar structure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The time-based RSUs (the "Time RSUs") vest ratably over five years. The performance-based RSUs (the "Performance RSUs") cliff vest at the end of a three-year performance period based on the Company's relative performance to the identified peer group with respect to its return on average equity, efficiency ratio and total nonperforming assets ratio, with each equally weighted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The total number of RSUs granted to Messrs. Nelson, Olafson, and Winterbottom in 2022 was 15,000 each, the same as the prior year. In each case, 7,500 are Time RSUs and 7,500 are Performance RSUs. The total number of RSUs granted to Ms. Funk and Mr. Peters in 2022 was 12,000. In each case, 6,000 are Time RSUs and 6,000 are Performance RSUs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• RSUs granted to our NEOs do not pay or accrue dividends, or dividend equivalents, during the applicable vesting periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 27

*Pay Mix*

Consistent with our philosophy of aligning executive pay with the short- and long-term performance of the Company, the elements of our executive compensation program evolve and are adjusted over time to support the business goals of the Company and West Bank, and to align the interests of executive management with the interests of our stockholders. To achieve these objectives, the Compensation Committee utilized the primary compensation elements — base salary, annual cash incentive opportunities and long-term equity incentive opportunities — to provide balanced pay packages to our executives. As demonstrated in the following chart, we compensated our NEOs in 2022 with a mix of fixed and variable short- and long-term pay elements, with a significant amount of performance-based and at-risk compensation.

![wtba-20230302_g19.jpg](wtba-20230302_g19.jpg)

*Our Compensation Philosophy and Best Practices*

Our pay-for-performance philosophy and compensation practices provide an appropriate risk-managed framework in which our executives are encouraged to achieve our strategic goals without excessive risk taking in their business decisions. We adhere to several best practices for executive compensation, including:

---

| | |
|:---|:---|
| **What We Do** | **What We Do Not Do** |
| ✔Strong emphasis on pay for performance | ✔No perquisites for executives |
| ✔Maintain rigorous stock ownership guidelines | ✔No golden parachute tax gross-ups |
| ✔Engage independent compensation consultants | ✔No hedging or pledging of Company stock |
| ✔Annual outreach with our institutional stockholders | ✔No dividends paid or accumulated on unvested RSUs |
| ✔ Annual say-on-pay vote | ✔No single-trigger cash or equity payments in the event of a  |
| ✔ Clawback policy for incentive compensation | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;change in control |
| ✔ 50 percent performance-based equity awards for NEOs |  |
| ✔ 3-year holding period on vested RSUs |  |

---

Put simply, our human resource philosophy is to have fewer people than our peers but to pay our people well for their performance. Our business model allows us to operate with fewer employees than the typical commercial bank of our size because we emphasize teamwork and sound practices and focus on business banking. Because we have fewer people, we need to have the right people and ensure that we offer what we consider to be above average pay in exchange for above average performance. In addition to attracting and retaining what we believe is superior talent, our approach also produces longevity in our workforce. The average tenure of our employees is over nine years.

This philosophy extends throughout the Company and includes our NEOs. The Company currently has five executive officers. To succeed with an atypically small team, our CEO leads and fosters a team approach with the non-CEO members of our executive management team who bring a diverse array of experience, expertise and backgrounds. Because of this team strategy, compensation for each of our non-CEO NEOs is historically similar. This approach has consistently proven to produce a winning teamwork structure for the Company and our stockholders.

We also believe in evaluating performance relative to our peer group and implementing performance considerations into our compensation decisions. Rather than setting absolute goals that can be manipulated and may lead to inappropriate risk taking, we emphasize sound behaviors that will lead to long-term success that is better than our peers. For example, we encourage growth by requiring that our bankers focus on relationship building by continuously setting appointments for sales calls and staying in regular contact with our customers. This has proven successful, as over the last decade, our loan portfolio has grown by approximately $1.8 billion, or nearly 20 percent on an average annual basis. None of this growth came from business acquisitions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 28

As we strive to grow, we avoid setting absolute goals of attaining a certain size by a certain time. Instead, we focus on relative metrics such as credit quality, which we believe is more important than the growth of the loan portfolio. We also look at return on average equity and efficiency ratio metrics, each on a relative basis to those of our peer group. We believe that our emphasis on attracting, retaining and appropriately motivating a well-paid team of superior talent, facilitating strong working relationships in that team and evaluating performance appropriately has produced our consistently strong financial results. The Compensation Committee remains committed to continuing our practice of incentivizing and encouraging the pursuit of excellence through our executive compensation program.

***Our Compensation Review Process***

*Role of Compensation Committee*

Our Compensation Committee is composed entirely of independent directors. It is fully responsible for our executive compensation program and reviews the program on at least an annual basis. The Compensation Committee has broad discretion when overseeing and reviewing each element of compensation. When reviewing compensation and making compensation decisions, the Compensation Committee considers the respective responsibilities of each NEO, their performance and experience and also competitive compensation levels based on information and data provided by our independent compensation consultant. In setting compensation levels and incentive goals, the Compensation Committee also reviews our financial results relative to our peer group, and it structures our compensation programs taking into account sound risk management and industry best practices.

The Compensation Committee's primary considerations for executive compensation decisions are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Key financial measurements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strategic initiatives related to our business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Compensation of peer group executives; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Proper risk management.

*Role of Executive Officers in Compensation Decisions*

As requested by the Compensation Committee, some members of management support the Compensation Committee's review and consideration of executive compensation by providing information for the Compensation Committee's review. In particular, the CEO provides recommendations with respect to the other NEOs. Such recommendations from the CEO address, among other items, financial results and analysis, performance evaluations, compensation provided to our NEOs (other than the CEO), technical and regulatory considerations and input on program design and possible modifications.

The Compensation Committee has final discretion over all compensation decisions regarding the CEO and each of the other NEOs. The Compensation Committee discusses the CEO's recommendations and accepts or adjusts them based upon its own assessment of Company strategic goals, executive responsibilities, internal pay equity and its independent review of market data. The CEO is not involved in discussions or determinations relating to his own compensation, and the executive officers are not present during the Compensation Committee's final discussion and determination of the types and amounts of compensation to be paid.

*Role of Compensation Consultant*

Under its charter, the Compensation Committee has the sole authority to select, retain, or replace compensation advisors. The Compensation Committee has historically engaged a compensation consultant to provide independent, objective analyses and professional opinions about executive and director compensation matters. The Compensation Committee believes that working with an independent compensation consultant furthers the Company's objectives to recruit and retain qualified executives, aids the Compensation Committee in aligning executives' interests with those of our stockholders and ensures that our executive compensation program appropriately motivates and rewards ongoing achievement of business goals.

The Compensation Committee engaged McLagan, a highly specialized, industry-focused team within Aon PLC's Human Capital Solutions business, as its independent compensation consultant in 2022. McLagan reports directly to the Chair of the Compensation Committee. McLagan provides input on marketplace trends and best practices relating to competitive pay levels, as well as developments in regulatory and technical matters, assists the Company in preparing this proxy statement, and otherwise provides no other services to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 29

<u>[Proxy Statement **Table of Contents**](#i395a7129f3904825b4c209607bc21912_10)</u>

The Compensation Committee reviewed McLagan's independence as contemplated by the Compensation Committee's charter and applicable Nasdaq rules and determined that there were no conflicts of interest and that McLagan is independent from the Company, the Compensation Committee members and our executive officers. McLagan was engaged to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Make recommendations for the composition of the Company's peer group;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provide a study of director and executive officer compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provide input on marketplace trends and best practices relating to competitive pay levels;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provide analysis and commentary on regulatory developments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provide proxy statement support; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provide technical support with regard to calculations for RSU usage and expense considerations.

*Use of Peer Group*

Market pay practices are one of many factors we consider in setting executive pay levels and designing compensation programs. The Compensation Committee uses our compensation peer group as one data point when setting executive pay packages. Although useful as a reference, the Compensation Committee does not target any particular percentile or range within this peer group as a specific objective. Instead, our compensation decisions are based on the full consideration of many factors, including, but not limited to, individual and Company performance, market data, internal equity, experience, strategic needs and responsibilities.

For compensation decisions for fiscal year 2022, the following 19 companies were selected as our peer group, as recommended by McLagan. The peer group was selected based on market capitalization, asset size and employee headcount. This is the same peer group used in 2021, except for the removal of Level One Bancorp, Inc. following its acquisition by First Merchants Corp.

***Elements of Compensation***

Our executive compensation program consists of several elements, each with a distinct objective that helps our overall program provide an integrated and competitive total pay package. The following overview explains the structure and rationale of the elements in our executive compensation program for 2022. The principal elements consist of base salary, annual cash incentive opportunities and long-term equity incentive opportunities, each of which is provided pursuant to the terms of an employment agreement between the Company and each NEO. A discussion of the terms of these agreements is contained in this proxy statement under the heading "Potential Payments upon Termination or Change in Control."

*Base Salary*

We compensate our NEOs with annual base salaries to provide a reasonable level of fixed income relative to their respective levels of responsibility. We want our base salaries to be competitive and commensurate with each NEO's experience and knowledge. As provided in our employment agreements with the NEOs, base salaries are established and eligible for review and possible upward adjustment on an annual basis.

*Annual Cash Incentive Opportunities*

Annual cash incentive opportunities are an important element of total compensation for our NEOs. By tying a meaningful portion of cash compensation to achievement of objectively measured financial results for the year, annual cash bonus opportunities support and encourage the achievement of the Company's business goals and strategies and lead to increased value for our stockholders.

Our executive employment agreements provide for participation in the Company's annual incentive plan. Thereunder, each NEO is eligible for a cash bonus as a percentage of his or her annual base salary, based upon the achievement of performance measures described below. Our plan caps maximum bonus opportunities to avoid encouraging excessive risk-taking and to avoid any focus on maximizing short-term results at the expense of long-term soundness. The plan also requires positive Company earnings in order for any bonuses to be paid.

The amount of any annual bonus actually earned is determined based upon quantitative and qualitative analyses of Company performance completed by the Compensation Committee. The quantitative analysis examines the Company's performance relative to our peer group with respect to three key financial measures. The qualitative analysis considers any items deemed relevant by the Compensation Committee, including, for example, regulatory actions, if any, and Company profitability and credit quality. Based on the qualitative analysis, the Compensation Committee may increase or decrease the bonus amounts indicated from the quantitative peer group comparison. The calculation and adjustment of bonuses rest within the Compensation Committee's sole discretion, and its determinations about bonuses are final.

The quantitative analysis has two parts:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)the Company's net profit; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)the Company's performance relative to our peer group, based on three key metrics (equally weighted):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.return on average equity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.efficiency ratio; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.total nonperforming assets to total assets ratio.

Each ratio is defined in Item 7 of our Annual Report on Form 10-K. The Compensation Committee selected these measures because they encompass important aspects of our financial performance: earnings, capital levels, expense control and asset quality. The nonperforming assets to total assets ratio performance metric is measured by comparing the average of the four fiscal quarter-ending ratios of the Company to the average of the four fiscal quarter-ending ratios of the peer group.

For performance periods prior to 2022, the Company utilized the Texas ratio as a performance criterion for annual bonus calculations and Performance RSU vesting. The Texas ratio was replaced with the total nonperforming assets to total assets ratio for the 2022 annual bonus calculation. While this new criterion also addresses an important qualitative measure of the Company's assets, it is more commonly reported by the Company's peer group members than the Texas ratio. The Compensation Committee expects future bonus and Performance RSU grants to include the total nonperforming assets to total assets ratio.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 31

<u>[Proxy Statement **Table of Contents**](#i395a7129f3904825b4c209607bc21912_10)</u>

Based on our ranking among our peers in each of these key metrics, our NEOs are eligible for a cash bonus payment equal to a percentage of salary, according to the following schedule, which remains unchanged from the prior year:

---

| | | |
|:---|:---|:---|
| **Performance** | **Peer Rating** | **Percent of Salary** |
| Maximum | At/above 75<sup>th</sup> percentile | 60% |
| Target | 50<sup>th</sup> percentile | 40% |
| Threshold | 25<sup>th</sup> percentile | 20% |
|  | Below 25<sup>th</sup> percentile | 0% |

---

For 2022 all NEOs share the same incentive opportunities relative to salary.

The Company's financial results for 2022 were above the 75th percentile of our peer group for each of the performance measures. For 2022, each of the NEOs received a cash bonus amount equal to 60 percent of their base salary.

*Long-Term Equity Incentive Opportunities*

Equity compensation is the third primary element of compensation for our NEOs. The purpose of annual equity grants is to provide long-term incentives that align with stockholder interests, tie pay to performance, provide a long-term planning horizon, mitigate adverse risk taking and attract and retain key employees.

The employment agreements with our NEOs generally provide for participation in the Company's equity incentive plan then in effect. Equity awards made prior to April 2021 were made under our 2017 Equity Incentive Plan (the "2017 Equity Plan"), which was adopted by our Board and approved by our stockholders in 2017. In April 2021, our stockholders approved the 2021 Equity Incentive Plan ("2021 Equity Plan") and upon such approval the 2017 Equity Plan was frozen with respect to future grants. The 2021 Equity Plan was designed to promote the Company's long-term financial success by providing a means to attract, retain and reward individuals who can and do contribute to such success and to further align their interests with those of the Company's stockholders. Awards vest, become exercisable and contain such other terms and conditions as determined by the Compensation Committee and set forth in individual agreements with the participants receiving the awards. As of December 31, 2022, there were 442,643 remaining shares available for issuance under the 2021 Equity Plan. The RSU awards granted to our NEOs in 2022 were made under the 2021 Equity Plan.

Pursuant to the terms of the 2017 Equity Plan and 2021 Equity Plan, and the award agreements governing the terms of the awards thereunder, unvested awards are forfeited upon early termination, other than a termination in connection with a change in control or due to the NEO's death, disability or retirement. Outstanding RSUs do not pay or accumulate dividend equivalents during the applicable vesting periods. In addition, the award agreements contain standard confidentiality and non-solicitation covenants for periods following termination of employment. Accordingly, the structure of our equity awards provides a retention incentive and provides important protections for the Company and our stockholders.

Prior to 2021 it was the Company's practice to grant awards solely in the form of RSUs that vest in annual installments tied to continued service over five years. In response to feedback received during our stockholder outreach in 2019 and 2020, the Compensation Committee adopted performance-based vesting for 50 percent of the customary RSU awards made to each of the NEOs, starting with our 2021 grants.

In light of the Company's outstanding performance in 2021, including record net income, the Compensation Committee decided that, in addition to the 2021 annual cash incentive payments received by our then NEOs, it was proper to make one-time restricted stock unit awards with a grant date value of $50,000 to each of the then NEOs. Accordingly, in January 2022, Messrs. Nelson, Olafson, Winterbottom and Peters, each received a one-time special grant of 1,804 Time RSUs, which vested on March 25, 2022 and are subject to a retention requirement such that 50 percent of the covered shares must be retained for a period of three years following the vesting date.

In March 2022, Messrs. Nelson, Olafson and Winterbottom were each granted 7,500 Time RSUs and 7,500 Performance RSUs. Ms. Funk and Mr. Peters were each granted 6,000 Time RSUs and 6,000 Performance RSUs. Each of the awards will be subject to a retention requirement such that 50 percent of the covered shares must be retained for a period of three years following the vesting date. The Time RSUs are scheduled to vest in five equal annual installments, on March 25 of 2023, 2024, 2025, 2026 and 2027.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 32

<u>[Proxy Statement **Table of Contents**](#i395a7129f3904825b4c209607bc21912_10)</u>

The Performance RSUs are scheduled to vest on March 25, 2025, based on the relative financial performance of the Company to the identified peer group during a three-year performance period consisting of the Company's 2022, 2023 and 2024 fiscal years (the "Performance Period"). The Performance RSUs are subject to three performance targets, each of which is to be weighted equally, and (i) with respect to ROE, calculated as an average of each of the three year-end results; (ii) with respect to efficiency ratio calculated as an average of each of the three year-end results; and (iii) with respect to nonperforming assets to total assets ratio, calculated as an average of each of the twelve quarterly results. Each of these ratios is compared to those of the companies in the SNL Small Cap US Bank Index ("Performance RSU Peer Group") as of the grant date. The Performance RSU Peer Group is "frozen" as of the grant date. Companies may drop out (but may not be added) if financial information becomes unavailable prior to the conclusion of the Performance Period.

These three measures are commonly utilized by banking organizations as reflective of important aspects of their overall financial performance. For the Performance Period, the maximum number of shares of 7,500 (for Messrs. Nelson, Olafson and Winterbottom) or 6,000 shares (for Ms. Funk or Mr. Peters) would be issued on March 25, 2025 for each of the participants if the Company achieves the 75th percentile performance on all three performance measures over the Performance Period. Up to one-third of the maximum number of RSUs subject to the award may be earned for achievement of a given performance metric. None of the Performance RSUs subject to a metric will be earned if performance is below threshold level, while approximately 33 percent will be earned for threshold level performance, approximately 67 percent will be earned for target level performance, and 100 percent will be earned for maximum level performance (or above). Performance between the threshold and maximum levels will earn a number of RSUs based on linear interpolation.

Upon the conclusion of the Performance Period, the performance of the Company and each member of the Performance RSU Peer Group will be calculated for each of the three metrics identified above, (i) with respect to ROE, as an average of each of the three year-end results; (ii) with respect to efficiency ratio, as an average of each of the three year-end results; and (iii) with respect to total nonperforming assets to total assets ratio, as an average of each of the twelve quarterly results. Based upon such calculations, the Company's percentile relative to the Peer Group will be determined. The Compensation Committee expects future awards to NEOs to have a similar structure.

For performance periods prior to 2022, the Company utilized the Texas ratio as a performance criterion for annual bonus calculations and Performance RSU vesting. The Texas ratio was replaced with the total nonperforming assets to total assets ratio for the 2022 Performance RSU grants. While this new criterion also addresses an important qualitative measure of the Company's assets, it is more commonly reported by the Company's peer group members than the Texas ratio. The Compensation Committee expects future bonus and Performance RSU grants to include the total nonperforming assets to total assets ratio.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 33

*Deferred Compensation Plan*

Our NEOs are eligible to participate in the West Bancorporation, Inc. Deferred Compensation Plan (the "Deferred Compensation Plan"). The Deferred Compensation Plan was adopted effective January 1, 2013, to provide key individuals, including our non-employee directors and the NEOs, with additional deferral opportunities in planning for retirement. The Deferred Compensation Plan is an unfunded, nonqualified deferred compensation plan that provides an opportunity for eligible participants to voluntarily defer receipt of a portion of their cash compensation. Though permitted under the plan document, the Company has not made any matching or discretionary Company contributions into the Deferred Compensation Plan on behalf of any of our NEOs. Pursuant to the terms of the Deferred Compensation Plan, the Compensation Committee has set the crediting rate equal to the prime rate, adjusted each January 1, on any amounts voluntarily deferred by plan participants. The crediting rate utilized under the plan is notionally based upon the prime rate and was 3.25 percent for 2022 and 7.50 percent for 2023. Our CEO and two other NEOs currently participate in the Deferred Compensation Plan. None of our non-employee directors are currently participating in the Deferred Compensation Plan.

*2023 Compensation Decisions*

With the assistance of market research completed by McLagan, the Compensation Committee has approved changes to NEO compensation for 2023. Base salary for the CEO will increase 14.8 percent to $590,000. Messrs. Olafson, Winterbottom will each receive a base salary increase of 7.1 percent to $375,000, and Ms. Funk and Mr. Peters will each receive a base salary increase of 8.3 percent to $325,000. The CEO's annual cash incentive opportunity will change to, as a percentage of base salary, 40 percent at threshold, 60 percent at target, 80 percent at maximum performance. The annual cash incentive opportunity will not change for the non-CEO NEOs in 2023. The CEO's long-term equity award is expected to increase to 8,500 Performance RSUs and 8,500 Time RSUs. The non-CEO NEOs' long-term equity awards are expected to be 7,500 Performance RSUs and 7,500 Time RSUs, which is an increase for Ms. Funk and Mr. Peters.

*Employment Agreements*

The Company has employment agreements with certain of its executives, including each NEO, that provide the NEOs with certain severance benefits, as described in this proxy statement under the heading "Potential Payments upon Termination or Change in Control." The Compensation Committee believes these severance benefits reflect market levels of benefits when they were negotiated and represent fair and appropriate consideration for the executive's agreement to the post-termination restrictive covenants. The Company believes that the protections afforded by the agreements are a valuable incentive for attracting and retaining top executives. The Company also believes that in the event of an extraordinary corporate transaction, the agreements could prove important to the Company's ability to retain top management through the transaction process and to provide motivation to the executives to act in the best interests of the Company and its stockholders before, during and after the transaction.

*Perquisites, Retirement and Other Benefits*

As a best practice, we have generally avoided the use of perquisites and other types of benefits for executives, emphasizing instead compensation tied to performance. In 2022, none of the NEOs received any perquisites. Our NEOs participate in our broad-based employee benefit programs, such as medical, dental, disability and life insurance coverage, on the same terms as other eligible employees.

Our NEOs are also eligible to participate in our 401(k) retirement plan on the same terms as other eligible employees. During 2022, the Company made a 100 percent Company matching contribution for participant deferrals into the 401(k) retirement plan, up to a maximum of six percent of a participant's pay. In addition, for 2022, the Company made an additional discretionary Company contribution into the 401(k) retirement plan of four percent of a participant's pay. The Company's contributions, in each case, were subject to applicable IRS limitations.

All employees of West Bank, including our NEOs, are eligible to receive a discretionary annual holiday bonus paid as a percentage of annual salary. Our NEOs participate in the holiday bonus program on the same terms as our other employees. In 2022, as in prior years, this discretionary bonus was equal to two percent of base salary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 34

***Regulatory Considerations***

As a publicly traded financial institution, the Company must comply with multiple layers of regulations when considering and implementing compensation decisions. Although these regulations do not set specific parameters within which compensation decisions must be made, they do require that the Company and the Compensation Committee be mindful of the risks associated with compensation programs designed to incentivize superior performance.

Under the FDIC's 2015 *Interagency Guidelines Establishing Standards for Safety and Soundness*, excessive compensation is prohibited as an unsafe and unsound practice. When determining whether compensation is excessive, the FDIC has directed financial institutions to consider whether aggregate cash amounts paid or non-cash benefits provided to an employee are unreasonable or disproportionate to the services the employee performs. The *Safety and Soundness* standards set forth a framework within which financial institutions should evaluate an employee's compensation, with factors including compensation history, internal pay equity and, if appropriate, comparable compensation practices at peer institutions. This framework also requires the Company to consider its overall financial condition.

Separately, the FDIC, the Federal Reserve, the Office of the Comptroller of the Currency and the Office of Thrift Supervision, together, issued the *Guidance on Sound Incentive Compensation Policies*, (the "Joint Guidance") in 2010. The Joint Guidance complements the *Safety and Soundness* standards and establishes a framework within which financial institutions must assess the soundness of their incentive compensation plans, programs and arrangements. Because the Joint Guidance is limited to senior executive officers and those other individuals who, either alone or as a group, could pose a material risk to the financial institution, it is somewhat narrower in scope than the *Safety and Soundness* standards. With respect to those individuals to which it applies, the Joint Guidance aims to ensure that any available incentive compensation arrangements appropriately balance risk and reward, are compatible with effective controls and risk management and have the support of strong corporate governance.

In addition to the foregoing, proposed rules under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act") that intend to implement further risk assessment guidelines and procedures may eventually be finalized by the financial institution regulatory agencies and the SEC. It is likely the Company will be subject to those further guidelines and procedures if and when they become finalized and effective. During 2011, the regulatory agencies issued initial proposed guidance with respect to the Dodd-Frank Act risk assessment guidelines and procedures, and they revised and re-proposed this guidance in 2016. Depending on whether and when the proposed rules are finalized, the earliest they would likely apply to the Company is for performance periods beginning on or after January 1, 2023. In large part, any guidance under the Dodd-Frank Act would likely restate and codify the frameworks presently set forth in the *Safety and Soundness* standards and the Joint Guidance.

The Company is also subject to the SEC's rules regarding risk assessment, which apply to all publicly traded companies. The SEC rules require the Company to determine whether any of its existing incentive compensation plans, programs or arrangements create risks that are reasonably likely to have a material adverse effect on the Company. Accordingly, the Company's Compensation Committee completes a risk assessment of the Company's compensation programs and components on an annual basis. The Committee has determined that the Company's incentive compensation plans, programs and arrangements do not create risks that are reasonably likely to have a material adverse effect on the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 35

------

<u>[Proxy Statement **Table of Contents**](#i395a7129f3904825b4c209607bc21912_10)</u>

The Compensation Committee believes that its regular, overall assessment of the compensation plans, programs and arrangements established for the Company's NEOs includes a sensible, responsible approach toward balancing risks and rewarding reasonable, but not necessarily easily attainable, goals. The Committee annually revisits the frameworks set forth in the *Safety and Soundness* standards and the Joint Guidance, as both are effective parts of the Committee's overall assessment of the balance between risk and reward in the Company's compensation arrangements. In addition, the Committee continues to monitor the status of the proposed guidance under the Dodd-Frank Act and remains prepared to incorporate into its risk assessment procedures any new guidelines and procedures as may be necessary or appropriate.

Finally, when making decisions about executive compensation, the Company also considers the impact of other regulatory provisions, including: Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"), regarding the tax deductibility of certain compensation; Section 409A of the Code regarding nonqualified deferred compensation; Section 280G of the Code regarding excise taxes and deduction limitations on golden parachute payments made in connection with a change in control; and the impact of FASB ASC Topic 718, which requires the Company to recognize the compensation cost of grants of equity awards based upon their grant date fair value.

***Other Compensation and Governance Policies***

*Share Ownership and Retention Guidelines*

We believe our NEOs and non-employee directors should have a significant equity interest in the Company. To promote equity ownership and align the interests of our executives and directors with those of our stockholders, we maintain the following share retention and ownership guidelines for our senior officers and directors.

---

| | |
|:---|:---|
| CEO | 3x base salary |
| Other NEOs or Executive Vice Presidents | 3x base salary |
| Non-employee Directors | 3x annual cash retainer |

---

The ownership guidelines are the same for each executive, including the CEO, to reflect the same team approach applicable to other elements of our executive compensation program. Until the stock ownership guideline levels are met, executives and directors are expected to retain at least 50 percent of any applicable shares received (on a net after-tax basis) pursuant to our equity incentive plans. If an officer fails to satisfy the guidelines, 25 percent of such officer's annual incentive bonus, if any, is paid in shares of Company stock until the ownership guideline is satisfied. A failure to satisfy the guidelines by a director is considered by the Nominating and Corporate Governance Committee when evaluating such director's qualifications for nomination. These guidelines are subject to periodic review by the Compensation Committee, and compliance is monitored on an annual basis. The guidelines for non-employee directors include annual cash retainer fees received from both the Company and West Bank.

For purposes of compliance with these guidelines, share ownership includes shares owned outright by the individual or his or her immediate family members who share the same household, shares held by the individual in an IRA account, fully vested shares held by the individual under a Company retirement plan and RSUs (both vested and unvested) granted to the individual under any Company equity incentive plan.

As of December 31, 2022, all of our NEOs and non-employee directors hold shares in excess of the requirements in the guidelines, with the exception of two non-employee directors who first became subject to the retention guidelines in 2021 and 2022, respectively, and one new NEO who first became subject to the retention guidelines in 2022. They are expected to make continuing progress towards compliance with the guidelines and until they individually reach the required minimums, they will each be required to retain at least 50 percent of any applicable shares received (on a net after-tax basis) pursuant to our equity incentive plans.

*Clawback Policy*

Effective as of January 27, 2021, the Company maintains a formal clawback policy which provides the Board with the authority to recover certain bonus or other incentive compensation (whether paid in cash or stock) paid to any NEO in appropriate circumstances where there has been a restatement of the Company's financial statements filed with the SEC. While the Compensation Committee believes its risk assessment procedures are effective, it is prepared to implement any additional steps that may be deemed necessary to fully comply with the rules required to be issued under the Dodd-Frank Act, when finalized and adopted by Nasdaq.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 36

------

<u>[Proxy Statement **Table of Contents**](#i395a7129f3904825b4c209607bc21912_10)</u>

In addition to the formal clawback policy, in the event the Company is required to seek or demand recoupment of any payments made to our NEOs pursuant to law, our employment agreements provide for return of any severance-related payments upon request of the Company. Additionally, all equity awards granted under our 2017 Equity Plan and the 2021 Equity Plan, are subject to cancellation, recoupment, rescission or payback in accordance with applicable law.

*Insider Trading Policy*

The Company's insider trading policy permits open market transactions in Company stock beginning the day after the second full trading day after quarterly earnings have been made public until the 10th day of the third month in the quarter. In addition, our NEOs may purchase Company stock through the 401(k) retirement plan. Changes to purchases under the 401(k) retirement plan may be made only during the period when open market transactions are permitted.

*Anti-Hedging Policy*

The Company's insider trading policy prohibits all employees and directors from entering into any hedging transactions involving the Company's stock.

*Anti-Pledging Policy*

The Company's insider trading policy prohibits all NEOs and directors from keeping Company stock in a margin account. In addition, NEOs and directors may not pledge Company stock as collateral for a loan.

*Acceleration of Equity Awards*

Our award agreements under the 2017 Equity Plan and the 2021 Equity Plan utilize a "double trigger" approach to vesting upon a change in control, rather than a "single trigger" approach under which awards would vest solely upon a change in control. Under our double trigger approach, vesting of our time-based equity awards occurs upon a change in control only if the outstanding equity awards are not fully assumed by the acquiror, or if they are assumed but the participant is subsequently terminated without cause or resigns for good reason. With respect to the Performance RSUs granted to our NEOs beginning in 2021, the awards vest immediately in connection with a change in control based upon the greater of actual performance through the date of a change in control or target-level performance without proration. We believe this approach provides adequate employment protection while reducing, for our stockholders' benefit, potential transaction costs associated with the awards, as compared to plans with single trigger acceleration upon a change in control.

*No Tax Gross-Ups*

Under Section 280G of the Code, an executive may be subject to excise taxes on certain benefits received in relation to a change in control of the Company. While some companies provide excise tax gross-ups to executives, to place the executive in the same tax position as if the excise tax did not apply, we do not believe it is necessary to provide this benefit to our executives. Our employment agreements with the NEOs therefore omit any provision for such a gross-up.

**Potential Payments upon Termination of Employment or Change in Control**

Each of our NEOs is party to an employment agreement with the Company and West Bank pursuant to which the NEO is entitled to a minimum annual salary and participation in our annual incentive plan and other benefit plans.

The table below sets forth the estimated amount of compensation payable to each of our NEOs upon termination of such NEO's employment in the event of (1) the NEO's disability or death, (2) termination by the Company without cause or by the officer for good reason, in each case other than in connection with a change in control or (3) termination by the Company without cause or by the NEO for good reason, in each case during the period beginning six months before, and ending 24 months after, a change in control. The amounts shown assume the termination was effective as of December 31, 2022, and that the price of Company stock as of termination was the closing price of $25.55 on December 30, 2022 (the last trading day of the year). The value of the Performance RSUs included in the "Acceleration of Stock Awards" rows is reported at maximum performance. The actual amounts to be paid can be determined only following the NEO's termination. We do not provide any benefits to our NEOs solely as a result of a change in control (no single-trigger benefits).

*Termination and Change in Control Benefits under 2017 and 2021 Equity Incentive Plans*

All awards under the 2017 Equity Plan and the 2021 Equity Plan then held by the participant will become fully vested immediately if (1) such plans and their respective award agreements are not fully assumed in a change in control, or (2) such plans and their respective award agreements are fully assumed in the change in control and the participant is terminated by the Company or a subsidiary without cause or the participant resigns for good reason.

Further, under the 2017 Equity Plan and the 2021 Equity Plan, all RSUs generally will become fully vested upon the participant's termination of service due to the participant's disability or death. In the event that the participant retires (as defined under each plan), the outstanding RSUs will continue to vest as scheduled provided that the participant signs a release and waiver and does not compete with the Company.

Under the 2021 Equity Plan, with respect to the Performance RSUs granted to our NEOs in 2021 and thereafter, the awards will vest immediately in connection with a change in control based upon the greater of actual performance through the date of a change in control or target level performance without proration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 44

*Termination under Deferred Compensation Plan*

In the event of a change in control of the Company or the participant's separation from service due to death or disability, amounts deferred by a participant will be distributed in a lump sum, and Company contributions, if any, will be distributed in accordance with the participant's elections.

**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 our median employee's annual total compensation and the annual total compensation of Mr. Nelson, our President and Chief Executive Officer (the "Pay Ratio") as of December 31, 2022. The Pay Ratio, as set forth below, is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K.

We identified our median employee as of December 31, 2021, excluding Mr. Nelson, using a measure of "total cash compensation," which is defined as the sum of base salary, bonus, incentives, holiday, paid time off and overtime pay, as reflected in our payroll records. We believe this is a reasonable measure of total compensation. Our employee population consisted of 181 employees as of December 31, 2021. This population includes all full-time and part-time employees. We annualized the compensation of employees who were hired during 2021, based on the portion of the year for which they were employed. No full-time equivalent adjustments were made for part-time employees. Since we do not widely distribute annual equity awards to our employees, such awards were excluded from our compensation measure for identifying our median employee.

To calculate the 2022 ratio of compensation of our median employee to that of Mr. Nelson, we calculated the median employee's annual total compensation consistent with the calculation of Mr. Nelson's annual total compensation as reported for 2022 in the "Total" column of the Summary Compensation Table included in this proxy statement. This includes total cash compensation as described above as well as Company matching and discretionary contributions to participants in our 401(k) retirement plan and equity awards, as applicable. The annual total compensation for the median employee was $72,040. Mr. Nelson's total compensation was $1,262,648. The Pay Ratio of Mr. Nelson's annual total compensation to the annual total compensation of the identified median employee as of December 31, 2022 was approximately 17.5 to 1.

**Pay Versus Performance** 

In August 2022, the SEC adopted final rules (the "Final Rules") implementing Section 14(i) ("Section 14(i)") of the Exchange Act, as added by Section 953(a) of the Dodd-Frank Act. The Final Rules and Section 14(i) require registrants to disclose the relationship between executive compensation registrants actually paid and the financial performance of the registrants. In accordance with the Final Rules and Section 14(i), the following tabular and graphical disclosures set forth the relationship between the compensation actually paid to our NEOs and our financial performance.

Section 14A of the Exchange Act requires the Company to conduct an advisory stockholder vote to approve the compensation of NEOs. This proposal, commonly known as a "say-on-pay" proposal, gives stockholders the opportunity to endorse or not endorse the Company's pay program for its NEOs. We currently hold our say-on-pay vote every year. The Company is requesting stockholder approval, on an advisory basis, of the compensation of the Company's NEOs for 2022 as listed in the Summary Compensation Table, appearing in the "Executive Compensation" section in this proxy statement, and as described in more detail in this proxy statement. The Company believes that its executive compensation programs, as explained in the "Executive Compensation" section of this proxy statement, are straightforward and reasonable. As explained, the general objectives of, and important factors for, the Company's executive compensation program include significant emphasis on the long-term success of the Company through long-term performance of its executives. Stockholders are urged to carefully read the "Executive Compensation" section of this proxy statement, as well as the Summary Compensation Table and narrative disclosures that describe the compensation of our NEOs in 2022. The Board has previously approved the 2022 compensation.

The following resolution is submitted for stockholder approval:

"RESOLVED, that West Bancorporation, Inc.'s stockholders approve, on an advisory basis, its executive compensation as described in the section captioned 'Executive Compensation' and the tabular disclosure regarding named executive officer compensation contained in the West Bancorporation Inc. proxy statement dated March 7, 2023."

Approval of this resolution requires that the number of votes cast "FOR" the proposal exceed the number of votes cast "AGAINST" such proposal. In tabulating the votes, abstentions and broker non-votes will be disregarded and have no effect on the outcome of the vote. While this say-on-pay vote is required, as provided in Section 14A of the Exchange Act, it is not binding on the Board and may not be construed as overruling any decision by the Board. However, the Compensation Committee will take into account the outcome of the votes when considering future compensation arrangements.

**INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FEES AND SERVICES**

**Proposal 3. <u>Ratify the Appointment of Independent Registered Public Accounting Firm.</u>** 

The Audit Committee of the Board has reappointed RSM US LLP ("RSM"), independent registered public accountants, as the Company's independent registered public accounting firm for the year ending December 31, 2023. RSM will conduct the annual audit of the Company and its subsidiaries for 2023. RSM has served as the Company's independent registered public accounting firm since 1998. In support of the reappointment of RSM as the Company's independent registered public accounting firm, the Audit Committee considered the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The firm's independence, objectivity and professional skepticism;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The firm's compliance with the SEC requirement to rotate the lead engagement partner and concurring review partner every five years;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Quality of services provided;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Quality of communication and interaction with the firm;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A review of the firm's most recent Public Company Accounting Oversight Board ("PCAOB") inspection report; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Audit and non-audit fees.

The Company is asking its stockholders to ratify the appointment of RSM as the Company's independent registered public accounting firm for 2023. A description of the fees for services rendered by RSM for 2022 and 2021 and a description of the Company's policy regarding the approval of independent registered public accountants' fees are set forth in the next sub-section.

In the event the stockholders fail to ratify the appointment, the Audit Committee will consider this factor when making any future determination regarding RSM. Even if the selection is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time if it determines that such a change would be in the best interests of the Company and its stockholders. Ratification of the appointment of RSM requires that the number of votes cast "FOR" the proposal exceed the number of votes cast "AGAINST" such proposal. In tabulating the votes, abstentions and broker non-votes will be disregarded and have no effect on the outcome of the vote.

A representative from RSM will be present at the Annual Meeting. The representative will have the opportunity to make a statement and will be available to respond to appropriate questions from stockholders.

**Audit Fees**

During the period covering the fiscal years ended December 31, 2022 and 2021, RSM performed the professional services listed in the following table.

---

| | | |
|:---|:---|:---|
| | **2022** | 2021 |

| Audit-related fees <sup>(2)</sup> | **84000** | 31000 |
| Tax fees <sup>(3)</sup> | **12978** | 9503 |
| All other fees <sup>(4)</sup> | **12345** | 9660 |

(1)Audit fees represent fees for professional services provided for the audit of the Company's annual financial statements, review of the Company's quarterly financial statements in connection with the filing of current and periodic reports and reporting on internal controls in accordance with Section 404 of the Sarbanes-Oxley Act.

(2)Audit-related fees represent fees for professional services provided for the audit of the Company's 401(k) retirement plan and fees related to procedures performed in conjunction with the Company's subordinated debt offering in 2022.

(3)Tax fees represent fees for professional services related to tax compliance, which included review of tax returns, tax planning and advice, and a cost segregation study in 2022.

(4)All other fees represent fees for information technology services.

The Audit Committee considered whether the non-audit services provided to the Company by RSM are compatible with maintaining RSM's independence and concluded that the independence of RSM is not compromised by the provision of such services. The Audit Committee pre-approves all audit services and permitted non-audit services, including the fees and terms of those services, to be performed for the Company by its independent registered public accounting firm prior to engagement.

**GENERAL MATTERS**

**QUESTIONS AND ANSWERS**

---

| | |
|:---|:---|
| **What is a proxy statement?** | A proxy statement is a document required by the Securities and Exchange Commission (the "SEC") that, among other things, explains the items on which you are asked to vote on at the Annual Meeting. |
| **Why did I receive access to this proxy statement and proxy card?** | We have made the proxy materials available to you over the internet because you were a stockholder of record of the Company at the close of business on February 17, 2023 (the "Record Date"). As a stockholder of record on the Record Date, you are entitled to vote at the Annual Meeting. This proxy statement describes the matters that will be presented for consideration by the stockholders at the Annual Meeting. It also gives you information concerning those matters to assist you in making an informed decision on each matter.<br>If you vote pursuant to the instructions set forth in the notice and herein, you appoint the proxy holders as your representatives at the Annual Meeting. The proxy holders will vote your shares as you have instructed, thereby ensuring your shares will be voted whether or not you attend the Annual Meeting. Even if you plan to attend the Annual Meeting, we ask that you instruct the proxies how to vote your shares in advance of the meeting just in case your plans change. |
| **Why did I receive a notice regarding the internet availability of proxy materials instead of paper copies of the proxy materials?** | We are using the SEC's notice and access rule that allows us to furnish our proxy materials over the internet to our stockholders instead of mailing paper copies of those materials to each stockholder. As a result, beginning on or about March 7, 2023, we sent our stockholders by mail a notice containing instructions on how to access our proxy materials over the internet and vote. **This notice is not a proxy card and cannot be used to vote your shares.** If you received a notice this year, you will not receive paper copies of the proxy materials unless you request the materials by following the instructions on the notice.  |
| **What matters will be voted on at the meeting?** | You are being asked to vote on the following matters proposed by our Board: <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)the election of 12 directors to serve on the Board until the next annual meeting of stockholders and until their successors are elected and qualified; <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)the approval, on a nonbinding basis, of the 2022 compensation of the named executive officers, commonly known as a "say-on-pay" proposal; and<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)the ratification of the appointment of RSM US LLP as our independent registered public accounting firm for the 2023 fiscal year. <br>These matters are more fully described in this proxy statement. We are not aware of any other matters that will be voted on at the Annual Meeting. However, if any other business properly comes before the meeting, the persons named as proxies for stockholders will vote on such matters in a manner they consider appropriate. |
| **How do I vote?** | After reviewing this document, please submit your proxy using any of the voting methods indicated on the notice. You may vote by telephone, by internet, by mail if you complete, sign, date and mail the proxy card you received in the mail, if you received paper copies of the proxy materials, or in person at the Annual Meeting. By submitting your proxy, you authorize the individuals named in it to represent you and vote your shares at the Annual Meeting in accordance with your instructions. Your vote is important. **Whether or not you plan to attend the Annual Meeting, please submit your proxy card promptly in the enclosed envelope, or through the internet or via telephone by following the instructions on the proxy card.**<br>If you sign and return your proxy card but do not mark the card to provide voting instructions, the shares represented by your proxy card will be voted "FOR" all 12 nominees named in this proxy statement, "FOR" the approval of the say-on-pay proposal and "FOR" the ratification of the appointment of RSM US LLP as our independent registered public accounting firm for the 2023 fiscal year.<br>If you are a beneficial owner and a broker or other fiduciary is the record holder of your shares (which is usually referred to as "street name" ownership), then you received this proxy statement from the record holder of the shares that you beneficially own. The record holder should have given you instructions for directing how the record holder should vote your shares. It will then be the record holder's responsibility to vote your shares in the manner you direct.<br>If you want to vote in person, please come to the Annual Meeting. We will distribute ballots to anyone who wants to vote at the meeting. Please note, however, that if your shares are held in the name of a broker or other fiduciary (i.e., in street name), you will need to arrange to obtain a legal proxy from the record holder to vote in person at the meeting. Even if you plan to attend the Annual Meeting, we ask that you complete and return your proxy card or vote via the internet or by telephone in advance of the Annual Meeting in case your plans change. |

| | |
|:---|:---|
| **If I hold shares in the name of a broker, who votes my shares?** | If your broker holds your shares in its name and you have not provided voting instructions for your shares, your broker may choose to either leave your shares unvoted or vote your shares on certain "routine" matters on which the broker is deemed to have discretionary voting authority. The ratification of the appointment of a company's independent registered public accounting firm is considered a routine matter, while the election of directors and the approval of say-on-pay proposals are considered nonroutine matters. Thus, if you do not provide instructions to your broker as to how it should vote the shares beneficially owned by you, your broker will be able to vote on the ratification of the appointment of RSM US LLP as our independent registered public accounting firm but will not be permitted to vote on the election of directors or the approval of the say-on-pay proposal. If your broker does not receive instructions from you on how to vote on a particular matter on which your broker does not have discretionary authority to vote, your broker will return the proxy to us indicating the broker does not have authority to vote on these matters. This is referred to as a "broker non-vote" with respect to the nonroutine matters and will affect the outcome of the voting as described below under "What options do I have in voting on each of the proposals?" Therefore, we encourage you to provide directions to your broker as to how you want your shares voted on all matters brought before the Annual Meeting. |
| **If I hold shares in the West Bancorporation 401(k) retirement plan, who votes my shares?** | If you are a holder of stock in the Company's 401(k) retirement plan (the "Plan"), you can direct the trustee of the Plan (the "Trustee") how to vote the number of shares you hold in the Plan for each proposal included in this proxy statement. If you do not provide timely voting directions to the Trustee, then the Trustee shall vote the shares held for your benefit in the same proportion as those shares of stock held in the Plan for which the Trustee has received proper directions for voting. |
| **What if I change my mind after I return my proxy?** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If you hold your shares in your own name, you may revoke your proxy and change your vote at any time before the polls close for the meeting. You may do this by:<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• signing another proxy card with a later date and returning that proxy card to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• timely submitting another proxy via the internet;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• timely submitting another proxy via telephone;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sending notice to us at the address below that you are revoking your proxy; or<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• voting in person at the meeting.<br>All written notices of revocation and other written communications with respect to revocation of proxies should be sent to Broadridge Financial Solutions, Inc., 51 Mercedes Way, Edgewood, NY 11717. If you hold your shares in the name of your broker and desire to revoke your proxy, you will need to contact your broker. |
| **How many votes do we need to hold the Annual Meeting?** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The holders of a majority of the outstanding shares of the Company entitled to vote as of the Record Date must be present in person or by proxy at the meeting in order to hold the meeting and conduct business. Shares are counted as present at the meeting if the stockholder either:<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• has properly submitted a signed proxy card or other form of proxy (through the internet or telephone); or<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• attends the Annual Meeting in person.<br>Shares of common stock held by stockholders abstaining from voting but otherwise present at the meeting in person or by proxy, votes withheld, and broker non-votes are included in determining whether a quorum is present. On the Record Date, there were 16,640,413 shares of common stock issued and outstanding, all of which were entitled to vote. Therefore, at least 8,332,207 shares need to be present, in person or by proxy, at the Annual Meeting to conduct business. Each share of common stock is entitled to one vote.  |
| **What happens if a nominee is unable to stand for re-election?** | The Board may, by resolution, provide for a lesser number of directors or designate a substitute nominee. In the latter case, shares represented by proxies may be voted for a substitute nominee at the discretion of the proxy holders. Proxies cannot be voted for more than 12 nominees. We have no reason to believe any nominee will be unable to stand for election. |

|:---|:---|
| **What options do I have in voting on each of the proposals?** | The directors are elected by a plurality of the votes cast by the shares entitled to vote, and the 12 nominees receiving the greatest number of votes cast "FOR" their election will be elected as directors of the Company. Votes withheld from any nominee will have no effect on the election of directors if the number of nominees is not greater than the number of directors to be elected due to the fact that such elections are by a plurality of the votes cast. <br>The number of votes cast "FOR" the proposal must exceed the number of votes cast "against" such proposal to approve the say-on-pay proposal and the ratification of the appointment of RSM US LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023. The vote on our executive compensation is advisory and is not binding on the directors of the Company. However, the Compensation Committee of the Board will consider stockholder votes in establishing our compensation plans for subsequent years.<br>Broker non-votes and abstentions will not be counted as votes cast, but will count for purposes of determining whether a quorum is present. So long as a quorum is present, broker non-votes and abstentions will have no effect on the outcome of the matters to be presented for a vote at the Annual Meeting.  |
| **Where do I find the voting results of the Annual Meeting?** | We will announce preliminary voting results at the Annual Meeting. The voting results will also be disclosed in a Current Report on Form 8-K that we will file with the SEC within four business days after the meeting. |
| **Who bears the cost of soliciting proxies?** | The Company will bear the cost of soliciting proxies. In addition to solicitations by mail, our officers, directors or employees, without extra compensation, may solicit proxies in person, via email or by telephone. We may reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to stockholders. |
| **What is householding?** | In some instances, only one notice is being delivered to two or more stockholders who share an address. The Company will promptly deliver a notice to any stockholder who makes such a request. Any stockholder who wishes to receive a separate copy of the notice in the future may notify Melissa L. Gillespie, Corporate Secretary, at 1601 22<sup>nd</sup> Street, West Des Moines, Iowa 50266, or by calling 515-222-2300. Alternatively, any stockholders sharing an address who are receiving multiple copies of the notice may also notify Ms. Gillespie to request delivery of only one copy. |

Certain directors of the Company have direct and indirect material interests in loans made by West Bank. All the loans were made in West Bank's ordinary course of business, on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with other persons not related to West Bank or the Company, and did not involve more than the normal risk of collectability or present other unfavorable features. None of the loans have been classified as nonaccrual, past due, troubled debt restructured or potential problem loans. The Board considered these loans when reviewing the independence of its directors and determined that such loans did not prevent the relevant directors from being able to serve as independent directors. Similarly, all certificates of deposit and depository relationships with these persons were made in the ordinary course of business and involved substantially the same terms, including interest rates, as those prevailing at the time for comparable depository relationships with persons not related to the Company or West Bank.

The Audit Committee's charter requires the Audit Committee to review and approve all related-party transactions that must be disclosed. All transactions between the Company or its subsidiaries and any related person, including loans made by West Bank involving $120,000 or more, are reviewed to determine whether all material facts of the transaction are known to the Audit Committee, the transaction complies with known legal requirements, and the transaction is fair to the Company and West Bank. The Audit Committee completed the required review of the fiscal year 2022 related-party transactions, and all transactions were approved and ratified.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;![wtba-20230302_g5.jpg](wtba-20230302_g5.jpg)2023 Proxy Statement \| 53

In order for a proposal from a stockholder to be eligible for inclusion in the Company's proxy statement and proxy card relating to the 2024 annual meeting of stockholders, the proposal must be received by the Company by November 8, 2023. However, if the date of the 2024 annual meeting is changed by more than 30 days from April 27, 2024, the proposal must be received a reasonable time before the Company begins to print and send its proxy materials for the 2024 annual meeting in order to be eligible for inclusion in the Company's proxy statement and proxy card. Upon timely receipt of any such proposal, the Company will determine whether to include such proposal in the proxy statement and proxy card in accordance with applicable SEC regulations governing stockholder proposals and the solicitation of proxies.

In order for a stockholder to propose other business to be considered at the 2024 annual meeting (but not included in the Company's proxy statement) the stockholder must deliver written notice of the proposed business to the Corporate Secretary of the Company not later than January 22, 2024, which is 45 days prior to the first anniversary date of the date stockholders received access to the proxy materials for the preceding year's annual meeting. The notice must contain the information required by the Company's bylaws.

Stockholders wishing to recommend names of individuals for possible nomination to the Board may do so according to the following procedures:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Submit the recommendation to Ms. Gillespie, Corporate Secretary of the Company, no later than November 8, 2023, which is 120 days prior to the anniversary of this year's proxy mailing date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Prove the person making the recommendation is a Company stockholder who owns shares with a market value of at least $2,000 at the time the submission is provided.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.If the person being recommended is aware of the submission, include a signed statement from such nominee so indicating.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.If the person being recommended is not aware of the submission, include an explanation why the nominee is not aware of his or her nomination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.Comply with the additional requirements as described in Article III, Section 15 of the Company's Amended and Restated Bylaws.

In addition to satisfying the foregoing requirements under our bylaws, to comply with the SEC's universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the board of directors' nominees must provide notice that sets forth the information required by SEC Rule 14a-19 no later than November 8, 2023 (unless we move the meeting up or delay it by more than 30 days from April 27, 2024).

The written submission must be mailed or hand delivered to:
