"First Bank" is a generic name shared by numerous financial institutions across the United States, and many have undergone name changes throughout their histories due to mergers, acquisitions, or rebranding initiatives. For example, institutions previously known as "FirstBank" were notably merged into PNC Bank following a major acquisition in 2025, which saw the rebranding of those branches to the PNC name. Because the name is so common, whether a specific "First Bank" has changed its name depends entirely on the history of the specific institution you are referencing. Often, regional banks change their names to avoid confusion in new markets or to better align with the branding of a parent organization after a corporate merger or ownership transition.
