Atlantic Union Bank Completes Merger with Sandy Spring Bank
In the previous year, Atlantic Union and Sandy Spring Bank, based in Olney, officially entered into a merger agreement. This agreement, valued at about $1.6 billion, involved Atlantic Union acquiring Sandy Spring in an all-stock deal. The merger finalized on April 1, 2025, resulting in the formation of the largest regional bank located in the Lower Mid-Atlantic.
On October 14, 2025, Atlantic Union Bank announced that it had successfully integrated all branches and operations of Sandy Spring Bank, officially uniting both entities under the Atlantic Union Bank brand. The sign at the main branch of Sandy Spring Bank was also replaced as part of this transition.
Sandy Spring, established in 1868 and headquartered in Olney, Maryland, reported assets amounting to $14.4 billion, with total deposits at $11.7 billion and loans at $11.5 billion as of September 30, 2024. The merger has propelled the combined institution to total assets of $39.2 billion, deposits of $32 billion, and loans totaling $29.8 billion. The merger notably enhances Atlantic Union’s reach in the Mid-Atlantic, adding 53 branches, nearly doubling its wealth management efforts, and increasing assets under management by over $6.5 billion.
Maria Tedesco, president and chief operating officer of Atlantic Union Bank, indicated that the bank’s team had been diligently working on integrating Sandy Spring’s systems and data since the merger announcement the previous fall. She noted, “This integration not only brings our services together across Virginia, Maryland, North Carolina, and Washington, D.C., but also reinforces our dedication to delivering the services and products our customers value.”
The merger received regulatory approval in February 2025 and was completed two months later, marking a significant advancement for Atlantic Union’s market presence in Maryland and bolstering its status as the premier regional bank in the lower Mid-Atlantic area.
As part of the merger initiatives, Atlantic Union Bank has pledged a $9.5 billion community impact plan designed to promote economic growth and financial accessibility throughout the communities it serves.
