Reviewed NIC structure change on 2019-05-24: RSSD 12937 → 2239288 (1). The location count above reflects the current combined network and is not itself a measure of organic branch growth. 4 structure changes are on record for this entity; see History & events for the full list.
Branch locations reflect the latest registered FDIC location release, not real-time openings. Opening/closing attribution to organic growth vs. merger activity remains unavailable beyond the reviewed structure changes noted above. Annual deposit market share by state is available separately, below.
Annual FDIC Summary of Deposits, by state, as of the 2025 snapshot effective 2025-06-30. Deposits and share are as of that retained annual snapshot, not a quarterly balance — do not compare directly to Call Report deposit figures reported elsewhere on this profile.
