Joseph W. Turner President and Chief Executive Officer

To our Stockholders, Stakeholders, and Team Members,

As we reflect on the year 2024, we are proud of what Great Southern has accomplished in an environment marked by both complexity and opportunity. Our theme this year, Resilient Growth: Building Long-Term Value, resonates deeply with our journey-a year in which we navigated economic uncertainties and heightened competition while remaining steadfast in our mission to deliver sustainable value to our stakeholders.

Our financial performance in 2024 underscores the strength of our business model and our commitment to disciplined execution. We generated net income of $61.8 million, or $5.26 per diluted common share, reflecting our ability to adapt to shifting market dynamics while maintaining a long-term focus on growth and stockholder value creation. Our success is grounded in a strong, customer-focused culture that fosters innovation, operational excellence, and financial discipline.

RESILIENCE THROUGH ADAPTABILITY AND DISCIPLINE Throughout 2024, resilience became our hallmark. Rising deposit costs and fluctuations in interest rates presented challenges, but through strategic balance sheet management and proactive interest rate positioning, we stabilized earnings and strengthened our capital base. Our net interest margin improved to 3.49% in the fourth quarter, up from 3.30% in the same period in 2023, showcasing our ability to navigate pressures while optimizing yields and controlling funding costs.

Our proactive approach to interest rate management played a key role in offsetting the impacts of rising deposit rates. As maturing deposits were repriced or replaced at higher market rates, we strategically managed funding costs while maintaining loan yield growth. We anticipate the 2024 Federal Reserve rate cuts will provide relief in 2025, contributing to further margin stabilization. Additionally, our proactive risk management contributed to continued outstanding asset quality. Non-performing assets declined to $9.6 million, representing just 0.16% of total assets, and net charge-offs fell to $155,000 in the fourth quarter-testament to our disciplined approach to lending and credit risk.

As a financial institution with a legacy of trust, we recognize that resilience is built on a foundation of long-term planning, strategic investments, and a customer-first approach. We have taken decisive action to ensure that we are not only weathering current economic headwinds but positioning ourselves for future success through enhanced lending strategies, careful liquidity management, and continued

operational efficiencies. By prioritizing capital preservation and strategic reinvestment, we continue to create sustainable financial strength for our stakeholders.

STRATEGIC GROWTH ACROSS KEY SEGMENTS Targeted loan growth remained central to our strategy, with gross loans increasing by $100.8 million during the year. Our multi-family residential loan portfolio led this growth, driven by sustained demand in key markets. Meanwhile, we managed a strategic transition of construction loans to completed multi-family residential and commercial projects, reflecting our ability to balance growth opportunities with prudent risk management.

We also recognize that banking is not just about numbers, but about supporting the individuals, families, and businesses that drive our local economies. Our small business lending initiatives expanded in 2024, helping local entrepreneurs and enterprises gain access to the capital they need to grow and thrive. Whether it is through commercial real estate financing, business lines of credit, or tailored banking solutions, we remain committed to serving the diverse needs of our customers.

Our loan pipeline remains strong, particularly in construction and multi-family lending, ensuring we will have ample opportunity to support our customers in 2025. We remain focused on meeting market demand while maintaining sound underwriting practices to ensure long-term portfolio stability. Additionally, we are committed to leveraging relationships within our communities to support small businesses, further

EXPENSE MANAGEMENT AND TECHNOLOGY INVESTMENTS

Our commitment to disciplined expense control allowed us to manage non-interest expenses at $141.5 million in 2024, consistent with the previous year, even as we continued investing in strategic initiatives. Our efficiency ratio was 64.40% in 2024, compared to 63.16% in 2023.

A key achievement in 2024 was working with our partners to identify opportunities to advance various technologies and solutions. Many of these projects will be completed during 2025. This large-scale technology transformation is more than an operational upgrade-it is a commitment to enhancing customer experience, increasing efficiency, and providing greater security in our banking services. With cybersecurity threats evolving, we have prioritized investments in cutting-edge security infrastructure, ensuring that customer data remains protected while enhancing digital banking capabilities.

In tandem with this reinvestment in core technologies, we are also implementing a comprehensive refresh of our products and services lineup, ensuring a renewed focus on addressing the evolving needs of both retail and business customers. By integrating advanced digital solutions, expanding online banking capabilities, and enhancing in-branch services, we are committed to providing seamless, secure, and convenient banking experiences.

• 7,400+ VOLUNTEER HOURS, VALUED AT MORE THAN $200,000 Employees actively engaged in mentorship programs, financial literacy workshops, environmental sustainability efforts, and hands-on community service projects.

We believe that by working together with local leaders, businesses, and nonprofit organizations, we can build a stronger, more inclusive financial ecosystem that benefits all.

Through these efforts, we have solidified our role as a responsible corporate citizen, strengthening relationships and reinforcing our commitment to fostering economic and social well-being across our footprint. We are immensely proud of the work we have accomplished.

LOOKING AHEAD TO 2025

As we move into 2025, our strategy will remain grounded in disciplined growth, prudent risk management, and forward-looking investments. We will complete the construction of a next-generation banking center in Springfield, Missouri, which will integrate state-of-the-art technology and flexible service models to elevate the customer experience. Additionally, we will expand our digital capabilities to ensure secure, intuitive, and efficient banking services tailored to the needs of today's customers.

We remain confident that our unwavering commitment to innovation, community service, and customer satisfaction will continue to define Great Southern Bancorp as an industry leader. By prioritizing long-term sustainability, enhanced financial inclusion, and operational excellence, we are not only reinforcing our leadership in banking but also ensuring a legacy of strength and prosperity for generations to come.
