MVB Bank Completes Acquisition of Potomac Mortgage Group

Potomac Maintains Name, Commences Integration with MVB’s Mortgage Operations

FAIRMONT, WV, Dec. 21, 2012 – MVB Financial Corp., (OTC Markets Group OTCQB: MVBF), today announced that it has closed its previously announced acquisition of northern Virginia residential mortgage company Potomac Mortgage Group, LLC (PMG). The purchase price was approximately $19 million in cash and MVB common shares.

With the addition of PMG’s annual production of mortgages, MVB’s subsidiary is expected to become a $1 billion mortgage production unit at a time when MVB Bank is experiencing record mortgage lending. The addition of PMG is expected to be accretive to MVB’s earnings beginning in the first quarter of 2013. PMG will retain its identity as a wholly-owned subsidiary of MVB Bank, Inc. PMG’s CEO Ed Dean will continue to operate the mortgage subsidiary as well as oversee MVB’s total mortgage operations.

PMG was rated in the Top 100 Mortgage Companies, based on mortgage loan production, in the country in 2011. This year, MVB has received the highest Superior 5-Star Rating from Bauer Financial, Inc. for each of its reporting periods for the overall safety, soundness and quality of the bank, ranking its credit quality among the best in the industry.

Commenting on the completion of this transaction, MVB Financial Corp. CEO Larry Mazza said, “We are pleased to have completed the purchase of PMG as it will strengthen MVB’s retail mortgage lending platform as well as enable PMG’s continued growth. Both organizations have achieved success in the retail mortgage lending arena that we believe will only be strengthened by a shared platform of talent, advanced technology and high quality operations.”
