"It has been a pleasure getting to know Alan and Melisa and the management team at Lone Star. We are very excited to have them join our organization. We continue to look for opportunities to enhance our presence in the West Texas area and Lone Star Bank’s locations in Lubbock, Midland/Odessa, Big Spring and surrounding areas are an excellent fit for us. The customers of Lone Star will be able to use any of our locations across Texas and Oklahoma after operational integration," David Zalman, Prosperity Senior Chairman and CEO.
