A Letter from David Kapavik about the Acquisition of SouthStar Bank

Dear Valued Customers, I am pleased to share the news about our bank’s future. The Dinsdale family, owners of Pinnacle Bancorp, Inc., have signed an agreement to acquire SouthStar Bank. We will join an established family of community banks. The transaction will occur early next year, but we will continue operating under the SouthStar Bank name through 2027. I will continue to serve as President and CEO, and our management team and staff will remain the same. I understand you may have concerns or skepticism about the change in ownership. But you have my commitment to continue taking care of you, as we have for the past 31 years I have served as President. I can say this confidently because the family buying the bank already operates their other banks with the same values as SouthStar. On behalf of Executive Vice President of Pinnacle Bancorp, Inc., Matt Dinsdale, I want to share the following message: “Under Pinnacle Bancorp, Inc., SouthStar Bank will continue to operate with local management, local decision-making, local teams, and local control, reflecting both organizations’ shared commitment to community banking. Our heritage and values will continue to build on SouthStar Bank’s strong established foundation for its employees, customers, and communities.” SouthStar Bank will remain the same great bank, with the same 5-star customer service tradition that you know and love that sets us apart from other financial institutions. Our Team and I are genuinely excited about this opportunity and confident in the future it creates for our customers and the communities we have proudly served since 1920. The branches and employees, who know you by name, will continue serving our customers. For daily questions or concerns, please continue to contact and visit your local branch or reach out to any of our loan officers who regularly help you. As a personal guarantee, I am also listing the Moulton branch phone number so you can call me if we are not living up to my commitment to serving you as we always have. I welcome your call at 361.596.4611. Thank you for your continued business and support! David Kapavik CEO & President
