Banking the Sunshine State

Florida’s $800B economy is 70% larger than any other state in the southeastern United States and maintains an attractive tax policy. If the Sunshine State was a country, Florida’s economy would be the 18th largest in the world – larger than Saudi Arabia, Poland, Chile and Argentina. With a population nearing 20 million and 1,000 more people moving down each day, Florida passed New York as the 3rd most populous state in the US. Why invest in Florida?

Summary and Investment Thesis Florida is an economic powerhouse and is dramatically improving CenterState is an attractive investment as one of the largest publicly traded banks headquartered in Florida Strong organic loan and deposit growth, along with M&A initiatives, continue to result in positive operating leverage and continued double digit EPS growth year over year Core Deposit Franchise with strong DDA base should result in upside to net interest margin performance in a higher rate environment
