FIRST BUSEY CORP /NV/

Busey is built upon a strong commitment to associate, customer, stockholder, and community, with its associates as the cornerstone of this unwavering commitment. Busey’s vision, Service Excellence in Everything We Do, starts with Busey’s dedication to its associates. Busey is deeply humbled to be consistently recognized nationally and locally throughout the Company’s footprint, including being named nationally among the Best-In-State Banks and America’s Best Banks by Forbes; the Best Banks to Work For by American Banker; and the Best Places to Work in Money Management by Pension and Investments. Additionally, Busey is consistently named among the Best Places to Work and Best Companies to Work For by associates and publications across our footprint. From exceeding the needs of customers and colleagues to serving their communities selflessly, Busey associates show unmatched dedication to the Company. Their shared experiences are what make these and other awards possible. Since Busey opened its doors 158 years ago, Busey has maintained its core values, creating a strong foundation and shaping its inclusive culture.

Busey remains committed to fostering a welcoming and supportive environment within its organization, the banking profession, and the communities in which it operates. Busey is dedicated to attracting and retaining top talent across a variety of backgrounds and experiences. Teams with varying beliefs and opinions promote productivity, creativity, and innovation, while better meeting and exceeding the needs of Busey’s customer base. Recruiting, supporting, and retaining a workforce with varying perspectives and ideas, while maintaining a welcoming culture, is the foundation of Busey’s core value—One Busey. Busey’s endeavors in this regard are reported to the Employee Benefit and Compensation Committee and to the Board's Enterprise Risk Committee, which hold the organization accountable to this core value at the highest levels of management.

Associate engagement is an important barometer of Busey’s cultural health. Busey regularly solicits feedback to understand the views of its associates about their work environment and Busey’s culture. The results from engagement surveys are used to implement programs and processes designed to enhance engagement and improve the associate experience. With a strong 90% participation rate and an approach focused on continuous improvement, 2025 results remained in-line with the prior year and exceeded expectations. One way Busey keeps associates informed and engaged is through quarterly update calls, which are conducted by Busey leadership. These calls provide important information about the financial health of the Company, but more importantly they provide a cultural touchpoint to solidify Busey’s commitment to its number one asset – its associates. A tenet of Busey’s engaged culture is a commitment to investing in associates through unique, award-winning training and development programs. In 2025, 47% of Busey’s associate base engaged in talent and leadership development programs. Since 2017, Busey has been a proud recipient of the Association for Talent Development’s BEST Award, which is presented to organizations that demonstrate enterprise-wide success as a result of employee talent development.

Additionally, Busey cares about the health and well-being of its associates and their families, as evidenced by a strong investment and an 86% participation rate in Busey’s innovative, holistic health and wellness program, B Well. Investments in B Well include stress management and mental wellness components, lifesaving biometric screenings, access to fitness and wellness coaches, onsite wellness centers, health club reimbursements, on-demand wellness streaming service, and Health Savings Account investments funded by the Company. In 2025, Busey was honored to be recognized among the Healthiest Employers in Illinois, St. Louis, and Florida and received a Silver Well Workplace Award by the Wellness Alliance.
