Southern National Bancorp of Virginia Inc. reports earnings of $1.0 million for its first full year of operations

For immediate release

Monday, January 22nd, 2007

Charlottesville, Virginia, January 22nd, 2007 – Southern National Bancorp of Virginia Inc. (NASDAQ: SONA) announced today that net income for the year ended December 31, 2006, was $1.0 million compared to a net loss of $2.3 million for the initial operating period from April 14, 2005 to December 31, 2005. Further comparisons are not meaningful since the periods are not comparable. Moreover, the net loss for the period ended December 31, 2005, included $1.2 million of pre-opening and organizational costs.

Net income for the fourth quarter of 2006 was $381 thousand up from $26 thousand for the fourth quarter of 2005. Net interest income after provision for loan losses was $1.7 million for the fourth quarter of 2006, up from $665 thousand in the fourth quarter of 2005. Non interest income was $94 thousand during the fourth quarter of 2006, compared to $43 thousand during the same quarter of the prior year. Approximately 80.4% of the growth in non interest income was accounted for by growth in account maintenance and deposit service fees primarily due to an increase in the number of deposit accounts.

Southern National Bancorp of Virginia, Inc. and its subsidiary Sonabank N.A. completed the acquisition of 1st Service Bank of McLean, Virginia as of the close of business on December 1, 2006. As a result, at the end of 2006 Sonabank had five branches in Virginia: one in Charlottesville, one in Clifton Forge and three in Northern Virginia. Georgia Derrico, CEO of Southern National Bank of Virginia stated: “The acquisition of 1st Service brings us into the heart of Fairfax County, which has the second highest median family income in the U.S. It is a market we know well. 1st Service was an excellent institution with superb customer service but handicapped by a legal lending limit of $1.3 million and limited product base. Since the


completion of the merger with 1st Service Bank, Sonabank has a legal lending limit of over $7.0 million and is aggressively offering state of the art products such as Check 21. Our new Regional Branch Manager has been in the Northern Virginia market for over twenty years. We expect to be competitive in this market.”

Total assets of Southern National Bancorp of Virginia were $290.6 million as of December 31, 2006, up from $122.9 million as of December 31, 2005. Of the growth in assets, $117.7 million was attributable to the acquisition of 1st Service. Net loans receivable grew from $74.0 million at the end of 2005 to $201.8 million at the end of 2006 with $91 million of the loan growth resulted from loans brought over from 1st Service. Of 1st Service’s loans at the time of closing, $74.8 million were single family residential loans. Between December 1, 2006 and the end of the year, Sonabank securitized with FNMA approximately $17 million of 1st Service’s loans and as of year end those loans were reflected on the balance sheet as securities. The loan growth during the year not associated with the 1st Service acquisition was $36 million, or 49%

Southern National Bancorp of Virginia’s allowance for loan losses as a percentage of total loans at December 31, 2006 remained relatively stable at 1.33% compared to 1.36% at the previous year-end.

Investment securities, available for sale and held to maturity, grew from $40 million at the end of 2005 to $59 million at December 31, 2006. The growth was predominantly the result of the approximately $17 million in residential mortgages of 1st Service Bank which were securitized in December 2006.

Non-interest bearing deposits increased from $6.3 million at December 31, 2005, to $19.2 million at December 31, 2006, primarily as a result of acquiring $11.6 million of non-interest bearing deposits from 1st Service Bank.

Interest bearing deposits rose from $70.9 million at December 31, 2005, to $196.6 million as of December 31, 2006. Of this increase, $67.3 million was acquired in the merger with 1st Service and $60.3 million was due to our increasing our brokered deposits in part to reduce 1st Service’s more expensive borrowed funds.

Total stockholders’ equity increased from $32.3 million as of December 31, 2005 to $68.2 million as of December 31, 2006. The increase was a result of the completion of the IPO in November which raised $26.4 million, the acquisition of 1st Service Bank, and net income for the year.

Going forward, the Office of the Comptroller of the Currency has approved Sonabank’s application to open a branch in Warrenton, Virginia adjacent to its already existing administrative offices. The lease has been signed and construction will begin shortly. The Warrenton branch is expected to open in March or April, 2007. Georgia Derrico, CEO stated: “We couldn’t to be more excited to be re-entering a market which many of us know well and where we have long standing relationships.”

 


Southern National Bancorp of Virginia is the holding company for Sonabank N.A., which operates 5 branches in Virginia.
