Service Excellence in Everything We Do. 2 | 2020 ANNUAL REPORT 2 | 2020 ANNUAL REPORT 2020 ANNUAL REPORT Dear Fellow Shareholders Corporate Update & Strategy With strategic priorities at the forefront, Busey continues to follow a disciplined, consistent and sustained approach toward growth while advancing a customer-centric and collaborative culture as the foundation of your organization. Since 2014, we’ve grown from $3.7 billion to $10.5 billion in assets by executing a sequence of strategic plans—resulting in successful, intentional growth. Although 2020 was strongly influenced by the devastating impact of the coronavirus pandemic on our associates, customers and communities, Busey simultaneously continued to pursue its strategic agenda. Building on critical organizational accomplishments in recent years, key priorities in 2020 included: monitoring and managing the impact of the coronavirus crisis; leveraging technological systems and enhancing overall systems architecture; implementing and refining a regional organic growth model across all business lines; deepening our enterprise risk management framework; and refining merger and acquisition processes and practices to prepare for future acquisitive growth. Beginning in Q1 2020 with the onset of the global pandemic, teams across Busey quickly delivered impactful solutions to protect and inform associates while supporting the customers and communities we serve. As the situation unfolded, we mobilized technological resources to transition more than 60% of associates to remote-working environments to prioritize safety while maintaining productivity, all while continuing to serve customers in the new reality that would remain for the duration of 2020. Concurrently—and in response to mounting economic impacts to customers—Busey developed and implemented its Financial Relief Program in late March 2020. The program included waiving certain fees, along with offering payment deferral for qualifying personal, auto, mortgage and home equity loans. Supporting customers through various external and internal loan relief programs, Busey implemented a six-month Loan Modification Program for commercial and retail clients. Busey’s commercial team processed nearly 1,100 modifications impacting more than $1.1 billion in balances while Busey’s retail team implemented more than 1,000 modifications to portfolio loans impacting over $135.5 million in balances. In further support of business customers, Busey participated in—and quickly organized around—the Small Business Administration’s (SBA) Paycheck Protection Program (PPP), funding approximately $750 million in loans to more than 4,500 businesses in 2020, positively impacting 85,000 jobs across the businesses supported through these efforts. Through December 31, 2020, Busey ranked fourth in the number of PPP loans of all banks headquartered in Illinois, based on published call report data. PPP efforts required tremendous teamwork across the organization to meet limited time restraints and rolling SBA guidance to implement the unique application, credit analysis, approval requirements and loan forgiveness processes associated with the program. Busey’s pandemic response efforts were viewed positively by both associates and customers. A Customer Confidence Pulse Survey revealed 92% of customers had confidence in the organization’s ability to meet their needs while 84% expressed satisfaction with communications received during the pandemic. In a separate, internal COVID-19 pulse survey, 86% of associates agreed or strongly agreed that Busey communicated a clear plan of action in response to coronavirus. Due to PPP loan funding and other Federal Reserve liquidity measures in response to COVID-19, Busey surpassed the $10 billion asset threshold in 2020. While we passed this important threshold earlier than anticipated, preparations have long been in place as we have continued to pursue M&A partnerships with those best positioned to build upon your organization’s strong heritage. With the announcement of our intent to acquire Glenview State Bank, we continue to plan for the financial, operational and regulatory implications of this significant asset milestone. Despite the financial market volatility fueled by the pandemic, Busey Wealth Management generated substantial organic growth in 2020. New assets under care grew by more than $550 million, representing Service Excellence in Everything We Do | 3 the second-best year in new asset generation for the team. With a 50% greater account-opening rate over 2019, Busey’s wealth management assets under care reached $10.2 billion at December 31, 2020. Additionally, promoting organic growth through organizational priorities, in January 2020 we successfully transitioned more than 100,000 customers to an enhanced eBank and Busey – Mobile app, offering improvements such as person-to-person (P2P) payments, faster payment processing, quick access to funds deposited through mobile deposit, improved debit card management options and access to eStatements. Modifications and enhancements to technological infrastructure and cybersecurity are integral to Busey’s scale, as we continue to improve the customer experience. By leveraging a regional growth model across all business lines, we strive to attract new customers and deepen existing customer relationships. This strategic focus on regionalization allows for “close to the customer” local leadership and decision-making while providing for efficiency and consistency through centralized, network-wide support services. Simply put, the regional model is about delivering best-in-class banking and wealth management services to our Pillars. Through these focus areas, strategic process improvements and investments in integrated technology platforms, we can serve customers more efficiently and effectively today and for years to come. As we reflect on a year like no other in recent memory, the organization is incredibly grateful for your trusted relationship and the opportunity to serve your unique financial needs. Capital Strength Through your support and our steadfast commitment to balance sheet strength, profitability and growth—in that order—Busey remains a strong, independent financial organization. Busey continues to navigate the economic environment triggered by COVID-19 effectively and prudently. We entered this crisis from a position of strength and remain resolute in our focus on serving our customers, communities and associates while protecting our balance sheet. First Busey’s investment grade credit rating with respect to its subordinated debt was affirmed by Kroll Bond Rating Agency in May 2020 after the onset of the pandemic. To further enhance our strong capital and liquidity positions, Busey completed a successful public offering of $125.0 million 5.25% Fixed-to-Floating Rate Subordinated Notes due 2030 during the second quarter of 2020. This issuance qualifies as Tier 2 capital for regulatory purposes. 4 | 2020 ANNUAL REPORT 4 | 2020 ANNUAL REPORT 4 | 2020 ANNUAL REPORT The organization’s strong capital levels, coupled with its earnings, have allowed us to provide a steady return to stockholders through dividends. We increased our dividend to $0.23 on January 12, 2021 to stockholders of record as of January 22, 2021 and payable on January 29, 2021—representing a nearly 5% increase from the previous quarterly dividend of $0.22 per common share and continuing an uninterrupted history of paying dividends to common stockholders since the bank holding company was organized in 1980. Another indicator of balance sheet strength is Busey’s tangible common equity1 (“TCE”), which increased to $921.1 million at December 31, 2020—an increase of 6.5% over $864.6 million at prior year-end. TCE represented 9.03% of tangible assets at December 31, 2020, compared to 9.26% the preceding year. As of December 31, 2020, Busey remained well-capitalized, exceeding regulatory standards with a Tier 1 Capital Ratio of 13.4% and Total Capital Ratio of 17.0%. Tangible book value per common share was $16.66 at December 31, 2020—up from $15.46 at December 31, 2019. The efficiency ratio for year-end December 31, 2020, was 55.68% compared to 61.29% for 2019. Busey remains focused on expense discipline—the efficiency ratios are impacted by acquisition expenses and other restructuring costs, resulting in an adjusted efficiency ratio1 of 53.02% and 56.35%, for the years ended December 31, 2020 and 2019, respectively. Busey’s net income was $100.3 million for the year-ended December 31, 2020, or $1.83 per diluted common share; adjusted net income1 was $108.7 million for the year-ended December 31, 2020, or $1.98 per diluted common share. During 2020, First Busey incurred $10.7 million in pre-tax non-recurring expenses relating to acquisitions and other restructuring costs. By remaining focused on effectively managing and allocating resources, Busey can continue to serve 1A non-GAAP financial measure, see Non-GAAP financial information in the Company’s 2020 Annual Report on Form 10-K for a reconciliation. 2020 ANNUAL REPORT customers’ needs, reward associates and provide returns to you, Busey’s valued shareholders. financial institution.

Best-In-Class Teams Across the organization, a deliberate approach to talent management has built high-performing, knowledgeable and accountable teams. To support the needs of a growing organization, we continue to implement best- in-class talent management and development practices. Driven by positive and engaged associates, Busey’s achievements in 2020 were unmatched. We are deeply humbled to be consistently recognized nationally and throughout our local organizational footprint as a Best Place to Work and Healthiest Employer. Busey is honored to be named among the Best Banks to Work For in the U.S. by American Banker since 2016 and a Best Place to Work in Money Management by Pensions and Investments since 2018.

Providing unwavering guidance, 6 | 2020 ANNUAL REPORT 6 | 2020 ANNUAL REPORT 2020 ANNUAL REPORT leadership and support, we continue to develop exceptional teams that seek to build upon the positive and collaborative culture of this remarkable organization. Looking Forward On December 27, 2020, the Economic Aid Act became law, extending the authority to make PPP loans through March 31, 2021 and revising certain PPP requirements. On January 6, 2021, the SBA issued Interim Final Rules related to first and second draw loans under the PPP and Busey began actively assisting customers under the extended PPP programs. Your organization remains steadfast in its response to the pandemic, addressing these challenges promptly, thoughtfully and strategically. Over the past year, the entire Busey organization banded together to ensure we are supporting Busey’s Pillars through these unprecedented times. Similarly, we are equally as diligent in efforts to identify new acquisition partners to propel Busey forward. On January 19, 2021, First Busey signed an agreement to acquire Cummins-American Corp. (CAC), the holding company for Glenview State Bank (GSB)—comprised of seven branches in the greater Chicagoland market, specifically the NorthShore and Northwest communities, with $1.4 billion in assets and $1.1 billion in wealth assets under care. The GSB partnership will enhance Busey’s existing deposit, commercial banking and wealth management presence in the Chicago-Naperville-Elgin, IL-IN-WI Metropolitan Statistical Area, improving deposit market share from 32nd to 20th while increasing our full-service branch footprint to 75 banking centers, including 60 throughout Illinois. The pro forma franchise, based on December 31, 2020 balances, will have combined total assets of $11.9 billion and over $11.3 billion in wealth assets under management. It is anticipated GSB will be merged with and into Busey Bank at a date following the completion of the CAC merger—expected in the second quarter of 2021, subject to customary conditions and required approvals. At the time of the bank merger, GSB banking centers will become banking centers of Busey Bank. Strategic acquisitions have resulted in successful, intentional growth for Busey’s banking and wealth management services. These strategic partnerships are developed with like-minded organizations best positioned to build upon Busey’s strong heritage—in Southwest Florida with Investors’ Security Trust, a prominent wealth management firm, closing in September 2019; across the metro east area of St. Louis with TheBANK of Edwardsville in January 2019; in west central Illinois with South Side Bank in October 2017; reaching Chicagoland with First Community Financial Bank in July 2017; entering Greater St. Louis with Pulaski Bank in April 2016; and expanding in the Peoria, Illinois area with Herget Bank in January 2015. Thank you for your support of our continued growth as we unite with another customer- and community-centric organization, offering significant growth possibilities for all of our Pillars—associates, customers, shareholders and communities. Summary Over the past several decades, there have been numerous periods of tremendous economic expansion and contraction. While the early ‘80s and ‘08 recessions were quite significant, the devastating reach of the coronavirus pandemic and the resulting health and socioeconomic uncertainties have been unprecedented. Since mid-March 2020, the sweeping impacts and significant resources needed to respond to the pandemic—and ensuing dynamic changes to business, competitive and economic conditions—necessitated constant evaluation and thoughtful reprioritization of strategic initiatives and priorities throughout the year. Despite unparalleled challenges brought on by COVID-19, Busey has remained poised to respond and adjust to the global crisis while acting as a source of strength for associates, customers and communities. Through sheer determination and dedication, the organization’s nearly 1,400 associates reaffirmed the spirit and strength of Team Busey with empathy, understanding and compassion. Simply stated, the performance of our associates during this pandemic has been truly remarkable. One learns more during times of trouble and uncertainty—I learned how much of a true blessing it is to work alongside our Busey associates. Because of a remarkable foundation—resilient associates, loyal customers, united community support and committed shareholders—we are in position to continue the organization’s organic and acquisitive growth. By remaining efficient, nimble and responsive, Busey continues to serve customers’ needs, reward associates for performance, and provide total value to you, our loyal shareholders. It is with sincere appreciation that I thank you, valued shareholders, for your sustained support. VAN A.
