Brand Transition - A Unified Bank Brand Across All Markets 25 On May 20th, we rebranded Union Bank & Trust to Atlantic Union Bank to reduce brand complexity and ensure recognition and clarity in the marketplace. Maintaining ‘Union’ in the new brand is key because it represents the unification of multiple banks that have come together over time to deliver better banking to our customers and has been a focal point for nearly 100 years. the new name references our geographic expansion throughout the Mid-Atlantic region from Maryland to North Carolina.
