Dear Stockholders: Our company has had another strong year, our second best on record. We believe that the key to our continuing success is not about being a certain size by a certain time. It is instead about having the best team, clarity around what is most important, and being purposeful about doing our best every day while having fun doing it. We do not set specific growth goals. Our focus is on having the right players on our team, providing a clear vision and strategy, supporting and engaging our communities, and consistency of what every West Banker does every day on purpose. In 2022, we completed construction of our new bank building in St. Cloud, Minnesota, and began construction of our new corporate headquarters in West Des Moines, Iowa, and our new bank building in Mankato, Minnesota. These buildings represent our commitment to our customers, employees and communities as we build on our successes and invest in our future. Our credit quality remains pristine, and we continue to see opportunities for high-quality loan growth, although at a slower pace than in recent years. We remain diligent in monitoring and managing our credit quality as we expect economic challenges due to the Federal Reserve's efforts to reduce inflation through aggressive interest rate increases. Our bankers are working hard every day to help our customers and communities navigate the uncertainties of the current economic and unprecedented interest rate environment. The pace of interest rate increases this year has put pressure on our net interest margin, as the increasing yield on the loan portfolio is being offset by the increase in deposit and funding costs. Changes in liquidity and competitive deposit pricing, resulting from volatility and uncertainty in the interest rate environment, has put upward pressure on our cost of funds. Despite these challenges, our capital position remains strong. We will continue to use our successful relationship-based business model to grow stockholder value. Our strong financial foundation and incredible team of dedicated West Bankers positions us well to face today's challenges and to capitalize on opportunities. We appreciate and thank you for your continued support and interest in our Company. Sincerely, David D. Nelson CEO and President, West Bancorporation, Inc.

3 We are proud of the national recognition we continually receive for our financial performance. Ranked No. 12 for 2021 among the top 23 performing community banks by Raymond James. West Bank has been selected eight out of the last nine years among a field of 229 publicly traded community banks with assets between $500 million and $10 billion. Ranked No. 13 on the S&P Global's list of America's top 50 performing banks with assets between $3 and $10 billion for 2021. West Bank was the only Iowa bank to make the list and one of the very few from the Midwest to be recognized. Metrics used to rank banks included return on tangible common equity, efficiency ratio and operating revenue growth. Recognized as one of the nation's top 200 banks with assets between $2 and $10 billion by American Banker based on three-year average return on equity as of December 31, 2021. West Bank ranked 39th overall and No. 1 of the 8 Iowa and Minnesota banks on American Banker's list. Despite increasing pressure on net interest margin in the second half of 2022, West Bank is heading into a time of forecasted economic uncertainty from a position of strength: • Net income in 2022 was $46.4 million, the second highest year in our history. • In 2022, loans increased by $286.6 million to $2.7 billion, while credit quality remains outstanding. As of December 31, 2022, our nonperforming loans as a percentage of total loans was 0.01% and there were no loans greater than 30-days past due. • Return on average equity remains strong at 20.71%.    

5 Ground-Breaking Revitalization On June 22, 2022, a crowd of city and industry officials, West Bankers and our construction teams gathered to celebrate the groundbreaking of the new West Bank headquarters. Construction of the 72,000-square-foot building began and is scheduled to be completed in 2024. The new headquarters, located at 3330 Westown Parkway in West Des Moines, is just one mile from the 22nd Street headquarters of the past 50 years. Clearly visible and offering easy access from the bustling thoroughfare of Interstate 235, our new location was strategically chosen to support the revitalization of the Valley West Mall area that has experienced an economic decline over the past decade. "As the oldest business of any type to be founded in West Des Moines, we believe it's very important to remain headquartered here," said David Nelson, West Bank Chair and CEO. "To further demonstrate our support for West Des Moines, we selected a site that is not only highly visible but also in need of reinvestment and redevelopment. As community leaders, we think it's important to support the community that has supported us for so long." Topping Off with Spirit After Iowa weather caused the first cancelation, a rescheduled celebration took place on November 21, 2022, to mark a milestone in the headquarters' construction. Following a tradition dated back to 700 A.D., West Bank held a "Topping Off" ceremony to thank the construction crew for their hard work and dedication to the progression of the building's foundational structure. The final beam, placed horizontally at the top of the building structure, was adorned by an Ironworkers traditional evergreen tree and an American flag, symbolizing the safe completion of a significant task. A West Bank flag was also placed on the beam, along with a banner including the signatures of West Bank employees and board members. The Future View The new, four-story West Bank headquarters is being built upon 7.5 acres of land and will feature a wraparound rooftop terrace along with other areas for hosting bank events. A lower-level walk-out patio will provide visitors and employees with a view of a beautiful water feature. The expansion of available office space will comfortably support current employees, numbering almost 100, while also providing room for growth well into the future.

STRONG VALUES Our team of West Bankers is always at the heart of everything we do. As a community bank, our focus remains on ensuring our values are lived out through continual learning, quality customer service, and growth as individuals and professionals. We're proud of the recognition our team members receive for their loyalty and dedication to providing outstanding banking experiences. Sara Larson and Gabe Olson both recently graduated from Iowa Banker's Association (IBA) Leaders in Advocacy, a 10-month program focused on building a base of leaders educated on banking industry issues and communicating effectively with legislators and regulators. In addition to creating an advocacy plan for their respective banks, program participants attended monthly meetings and visits to the state Capitol, and joined the IBA for its annual Capitol Hill Visit in Washington D.C. Jon Hummel was named the 2022 Leaders of Tomorrow "Up and Coming Banker of the Year" in July at the Community Bankers of Iowa's annual conference in Okoboji, Iowa. Recipients of the award were chosen for exemplifying the best in the future of independent community banking. Alice Jensen (retired 2021) was honored by the IBA for more than 50 years of service at West Bank. Jensen received the award during the September IBA Annual Convention in Des Moines. She was one of 24 individuals recognized for reaching the impressive 50-year milestone. Upon recognizing award recipients, IBA President and CEO John Sorensen said, "Each year, it's amazing to hear these bankers' stories of dedication to their communities and the many relationships they formed throughout their 50-plus years of service. We're honored to be able to celebrate the exemplary commitment and experience of Alice Jensen."

We have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of West Bancorporation, Inc. and its subsidiary as of December 31, 2022 and 2021, and the related consolidated statements of income, comprehensive income (not presented herein), stockholders' equity (not presented herein) and cash flows (not presented herein) for each of the three years in the period ended December 31, 2022; and in our report, dated February 22, 2023, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed financial statements is fairly stated, in all material respects, in relation to the consolidated financial statements from which it has been derived. Des Moines, Iowa \| February 22, 2023 Reconciliation of net interest income and net interest margin on an FTE basis to GAAP: Net interest income (GAAP) $91,740 $95,059 $82,833 Tax-equivalent adjustment (1) 1,122 1,202 707 Net interest income on an FTE basis (non-GAAP) $92,862 $96,261 $83,540 Average interest-earning assets $3,361,091 $3,152,138 $2,614,342 Net interest margin on an FTE basis (non-GAAP) 2.76% 3.05% 3.20% Reconciliation of efficiency ratio on an FTE basis to GAAP: Net interest income on an FTE basis (non-GAAP) $92,862 $96,261 $83,540 Noninterest income 10,208 9,729 9,602 Adjustment for realized securities gains, net - (51) (77) Adjustment for losses on disposal of premises and equipment, net 29 84 9 Adjusted income $103,099 $106,023 $93,074 Noninterest expense $45,051 $43,380 $39,054 Efficiency ratio on an adjusted FTE basis (non-GAAP) (2) 43.70% 40.91% 41.96% 2022 2021 2020 Non-GAAP financial measures include the Company's presentation of net interest margin on a fully taxable equivalent (FTE) basis and the presentation of the efficiency ratio on an FTE basis, excluding certain noninterest income and expenses. The following table reconciles the non-GAAP financial measures to GAAP. (1) Computed on a tax-equivalent basis using a federal income tax rate of 21 percent, adjusted to reflect the effect of the nondeductible interest expense associated with owning tax-exempt securities and loans. Management believes the presentation of this non-GAAP measure provides supplemental useful information for proper understanding of the financial results, as it enhances the comparability of income arising from taxable and nontaxable sources. (2) The efficiency ratio expresses noninterest expense as a percent of fully taxable equivalent net interest income and noninterest income, excluding specific noninterest income and expenses. Management believes the presentation of this non-GAAP measure provides supplemental useful information for proper understanding of the Company's financial performance. It is a standard measure of comparison within the banking industry. A lower ratio is more desirable. W E S T B A N C O R P O R A T I O N , I N C .
