Southern National Bancorp of Virginia Inc. Reports Record Earnings of $1.7 Million for 2007, Compared to $1.0 Million for 2006

CHARLOTTESVILLE, Va., Jan. 17, 2008 (PRIME NEWSWIRE) -- Southern National Bancorp of Virginia, Inc. (Nasdaq:SONA) announced today that net income for the year ended December 31, 2007, was $1.7 million compared to $1.0 million in the year ended December 31, 2006.

Income before income taxes for 2007 increased to $1.8 million from $1.0 million in 2006, an increase of 83%. Net interest income for 2007 was $10.7 million, up 80% from 2006.

Net income for the fourth quarter of 2007 was $147 thousand down from $381 thousand for the fourth quarter of 2006. The decline was attributable to the after-tax impact of an "other than temporary impairment" charge related to a FHLMC perpetual preferred stock held in the available-for-sale portfolio. Net interest income after provision for loan losses was $2.4 million for the fourth quarter of 2007, up from $1.7 million in the fourth quarter of 2006. Excluding the impairment charge, noninterest income was $281 thousand during the fourth quarter of 2007, compared to $80 thousand during the same quarter of the prior year. Approximately 20% of the growth in noninterest income excluding the impairment charge was accounted for by growth in account maintenance and deposit service fees primarily due to an increase in the number of deposit accounts. BOLI income in the fourth quarter of 2007 was $145 thousand compared to nothing in the fourth quarter of 2006.

Southern National Bancorp of Virginia Inc.'s subsidiary Sonabank N.A. opened a branch in Warrenton, Virginia in April, 2007. As a result, at the end of 2007 Sonabank had six branches in Virginia: its original branch in Charlottesville, one in Clifton Forge (a branch purchased from First Community Bank) and branches in McLean, Fairfax and Reston (resulting from the purchase of 1st Service Bank).

Despite the additional branch and the impairment charge, Southern National's efficiency ratio improved from 75% in 2006 to 69% in 2007, excluding the impairment charge.

On December 19th, 2007, Southern National Bancorp announced that it had entered into an agreement with Founders Corporation of Leesburg, Virginia to purchase certain assets and to assume its lease at 1 East Market Street in Leesburg in the 100 year old Loudoun National Bank building. Sonabank also submitted an application to open a branch at that location and, subject to approval by the Office of the Comptroller of the Currency, expects to open in Leesburg in early February. The Board of Directors of Founders Corp and certain other investors in Founders Corp will become the members of Sonabank's new Leesburg Advisory Board.

Total assets of Southern National Bancorp of Virginia were $377.3 million as of December 31, 2007, up from $290.6 million as of December 31, 2006. Most of the growth in assets was attributable to organic growth in the loan portfolio as well as an increase in investment securities. Sonabank closed $98.9 million of loans in 2007, net of participations sold and net of renewals. As a result, net loans receivable grew from $201.8 million at the end of 2006 to $257.9 million at the end of 2007.

Net Interest Margin

The net interest margin was 3.65% in 2007 compared to 4.01% in 2006. The decline in the net interest margin resulted in a variety of factors including:

First, the Federal Reserve reduced the Fed Funds target rate three times in late 2007. Sonabank is neither a buyer or seller of Fed Funds. However, over $98.0 million of our commercial loans and commercial real estate loans are priced at a spread over the Prime Rate which by custom moves with the Fed Funds target rate. On the liability side of our balance sheet much of our funding is based on certificates of deposit (CDs) which reprice over the course of months rather than immediately as is the case with the Prime Rate. Moreover, this fall and early winter when the Federal Reserve cut the Fed Funds rate, LIBOR which partially drives U.S. CD rates did not follow.

Second, in 2006 we owned no bank owned life insurance (BOLI). In 2007, we owned an average of $7.6 million of BOLI. Because the income from BOLI is not interest income, the opportunity cost of owning it causes net interest margin to be understated. We estimate this understatement to have reduced net interest margin by nine basis points.

Commercial mortgages grew 24% from December 31, 2006 to December 31, 2007. With Wall Street's vastly diminished interest in commercial mortgages we believe that this is a significant opportunity for all community banks. We have already seen and are negotiating potential loans on income producing properties, with owner guarantees and strong debt service coverage ratios which just months ago would have been snapped up by the conduits at very attractive yields. Those deals are just not available today. Going forward, this is an opportunity not only for Sonabank but for all of the community banks which are adequately capitalized and have money to lend. It is a paradigm shift between "structured finance" and old fashioned sensible lending.

Our residential mortgage loan portfolio declined from $63.1 million at December 31, 2006, to $51.9 million at December 31, 2007. Sonabank is not in the business of originating residential mortgages, except as an accommodation to our business banking customers. The vast majority of these loans resulted from our acquisition of 1st Service Bank in December 2006. None of them were sub-prime at origination. They are predominantly 5/1 hybrid adjustable rate mortgages (ARMs). During the first half of 2007, prepayments of the acquired ARMs were $9.1 million. In the second half of the year, however, prepayments slowed to $3.6 million as a result of dislocations in the mortgage market but more importantly as a result of the changed expectations on the part of the mortgage holders of what they would be facing when their mortgages repriced to 1/1 ARMs. They simply don't have to refinance to avoid having to pay a much higher rate. The alarmist rhetoric in the media to the contrary notwithstanding, the facts, at least as far as Sonabank's portfolio is concerned are as follows:



In 2008, $18.7 million of our hybrid ARMs reprice to 1/1 ARMs. The current coupon is 5.35%. They will reprice to a weighted average spread of 2.875% over the 1 year Treasury which as of today is under 3%. In other words, if they were all to reprice now the weighted average rate increase would be about a half percent.

As of the end of 2007, all of the residential mortgages which were added to Sonabank's portfolio as a result of the acquisition of 1st Service were subserviced by a third party fee subservicer. Sonabank plans to bring the subservicing function in house during the first quarter of 2008 to augment its control over the function.

The balances outstanding in home equity lines of credit and consumer loans both declined in absolute terms as well as in the percentage of the total portfolio. Neither one of these is a business line Sonabank wants to be in except as an accommodation to our business clients.

Commercial loans grew 172% from December 31, 2006 to December 31, 2007 as Sonabank benefited from two large commercial banks exiting its market area. We expect growth in this area to continue. Commercial lending has been and will continue to be a priority for Sonabank.

Loan Loss Provision/Asset Quality

Southern National Bancorp of Virginia's allowance for loan losses as a percentage of total loans was 1.33% at December 31, 2007 and December 31, 2006. As of December 31, 2007, the ratio of non-accrual loans and other real estate owned (OREO) to total assets was 1.07% compared to 1.14% as of September 30, 2007. The OREO is comprised of the finished lots Sonabank foreclosed on in early 2007 and one single family home. The non-accrual loans are both residential mortgages. After charge-offs the non-accrual loans and the single family home are carried on our books at $623 thousand approximately 30% below the combined original loan amounts of $886 thousand. These loans were acquired when Sonabank bought 1st Service Bank. They were not sub-prime at the time of origination.

One commercial mortgage in the amount of $443 thousand was over 60 days past due as of December 31, 2007. The collateral property is an owner occupied property in which the owner has experienced delays in bringing his business fully on stream.

Investment Securities

Investment securities, available for sale and held to maturity, grew from $57 million at the end of 2006 to $75 million at December 31, 2007. As of the year end 2007 the portfolio was comprised of the following:


 * We own 80,000 shares of FHLMC perpetual preferred 5.57% stock
   Series V. We bought it in April 2007 for approximately $25 a share
   or a total of approximately $2 million. It is an attractive
   investment since there is a 70% dividend exclusion for tax
   purposes. The stock is owned by hundreds of banks and thrifts. In
   November and December 2007, FHLMC issued approximately $6 billion
   in preferred stock with higher yields than the one we own. The
   market price on the stock we own declined to $17.25. Since then it
   has experienced some recovery and it opened on January 16, 2008 at
   $20.00 per share. FHLMC is rated AA3 by Moody's, AA- by Standard
   and Poors and A+ by Fitch. It has a U.S. Government mandated
   minimum capital ratio of 30%. We have had discussions with our
   auditors, and have decided, despite the fact that many of our peers
   have not done so, to take a conservative approach and recognize an
   "other than temporary impairment" charge, which we have done in the
   fourth quarter. This charge reduced our 2007 earnings from
   $2 million to $1.7 million. We do not believe the current market
   price of this security reflects its near-term potential, but
   current market conditions make it difficult to accurately forecast
   the time period required for the security to fully recover.
 * $15.4 million of 15 and 20 year fixed rate conventional FNMA and
   FHLMC residential mortgage backed securities.
 * $23.2 million of hybrid ARM FNMA and FHLMC mortgage backed
   securities, of which $12.6 million is the remaining balance of the
   $17 million created in December 2006 by securitization of
   residential mortgage loans acquired in the 1st Service Bank merger.
 * $13.7 million of single A rated pooled trust preferred securities
   (9 issues) of which more than 80% are bank issued paper with the
   balance in insurance company paper. As of the most recent trustees
   reports none of these issues are in default.
 * $8.3 million in one super-senior pooled trust preferred tranche
   rated AAA with 67% bank collateral and 33% insurance company
   collateral.
 * $6.8 million in two private label AAA rated collateralized mortgage
   obligations (CMOs). The average FICO score of the underlying loans
   at origination in one pool was 723 and 748 on the other. Of the
   1395 loans in the two pools only 21 had FICO scores in the 601-650
   range.
 * $6.0 million in agency CMOs.

Deposits

Non-interest bearing deposits decreased from $19.2 million at December 31, 2006, to $18.1 million at December 31, 2007.

Interest bearing deposits rose from $196.6 million at December 31, 2006, to $247.4 million as of December 31, 2007.

Stockholders Equity

Total stockholders' equity increased from $68.2 million as of December 31, 2006 to $69.3 million as of December 31, 2007. The increase was a result of the retention of earnings offset by an increase in the temporary impairment of our investment securities available for sale.

Southern National Bancorp of Virginia is the holding company for Sonabank N.A., which operates six branches in Virginia. A seventh branch is scheduled to open in Leesburg in February 2008, following approval by the OCC.

Addition to Staff

We are pleased to announce the addition to staff of Joseph L. Borrelli as Senior Vice President, Treasurer. Mr. Borrelli has had over 30 years of banking experience and previously was the founding CFO for two Virginia denovo banks, Cardinal Financial Corporation and Hometown Bank. Most recently he was the CFO for Founders Corporation of Loudoun, Inc. In addition to his treasury responsibilities Mr. Borrelli will head the investor relations function.
