NEWS RELEASE

CARDINAL ANNOUNCES FOURTH QUARTER EARNINGS

Cardinal Financial Corporation (NASDAQ: CFNL) (the “Company”) today announced quarterly earnings of $5.5 million, or $0.18 per diluted share, for the period ended December 31, 2013.  For the fiscal year, earnings were $25.5 million, or $0.82 per diluted share. This compares to earnings of $13.0 million, or $0.43 per diluted share, and $45.3 million, or $1.51 per diluted share, for the comparable three and twelve month periods of 2012.  Quarterly results were again influenced by the mortgage banking segment of the Company’s business, which reported a net loss of $1.6 million for the fourth quarter of 2013 compared to net income of $3.7 million in the year ago quarter. Additionally, the Company had a write down of $300,000 on investments as a result of the Volcker rule.  Cardinal also incurred approximately $160,000 of merger expenses in the fourth quarter 2013 and $464,000 for the 2013 year related to its acquisition of United Financial Banking Companies, Inc. (UFBC).

Selected Highlights

·                  For the full year, the commercial banking business segment reported net income of $33.9 million in 2013 versus $30.5 million in 2012, an 11% increase.

·                  During the most recent quarter, loans held for investment grew $76.6 million, or 16% annualized, and balances now surpass $2.0 billion. For the year, loans grew $236.7 million, or 13%.

·                  Asset quality remains excellent.  Nonperforming loans decreased to 0.08% of total assets, and the Company had net loan recoveries of 0.03% of average loans outstanding for the year ended December 31, 2013.  The Company continued to have $0 real estate owned and $0 loans 90 days or more past due and still accruing at December 31, 2013.  Non-accruing loans totaled $2.3 million at year end.

·                  Total deposits were $2.06 billion, a decrease of $184.9 million, or 8%, compared to December 31, 2012. Consistent with our focus of growing core, non-maturing deposits, demand deposit and interest checking account balances increased $132.4 million, or 19%, year over year.  Brokered deposits decreased $334.7 million from a year ago, which is correlated to a $411.8 million reduction of mortgage loans held for sale.

·                  Mortgage loan applications decreased 18% to $886 million for the current quarter versus $1.08 billion for the prior quarter. Refinance volume was 22% of total applications, up slightly from 19% in the prior quarter, but significantly down from 67% for the year ago quarter.  In 2013, purchase money originations were over $3.4 billion, an increase of approximately $1.5 billion over 2012 levels.

·                  All capital ratios exceed the regulatory requirements to be considered well-capitalized.  Tangible common equity capital (TCE) as a percentage of total assets was 10.58% at December 31, 2013.

Commercial Banking Segment Income Review

For the current quarter ended December 31, 2013, net income for the commercial banking segment decreased 23% to $7.8 million from $10.2 million for the year ago quarter.  The fourth quarter 2012 included approximately $2.4 million of net proceeds from bank owned life insurance.  Net interest income for the current quarter was $23.2 million compared to $23.9 million for the year ago quarter. The decrease in net interest income for the comparable quarters was due to lower average balances of interest earning assets resulting from a $341.3 million decline in the quarterly average of mortgage loans held for sale. The Company’s tax equivalent net interest margin was 3.65%, equal to the previous quarter, and up from 3.57% for the year ago quarter.  Over the last quarter, the yield on interest earning assets decreased 0.01%, while the cost of interest bearing liabilities also decreased 0.01%.

For the comparable annual periods ended December 31, 2013 and 2012, net income increased 11% to $33.9 million from $30.5 million.  Although the net interest margin has declined over the comparable periods from 3.61% in 2012 to 3.52% in 2013, net interest income increased to $90.6 million versus $89.5 million a year ago due to the growth in average earning assets of approximately $115.4 million for the year 2013.

The allowance for loan losses decreased to 1.37% of loans outstanding at December 31, 2013. The Company’s nonperforming assets decreased to 0.08% of total assets compared to 0.09% at the previous quarter end and 0.25% a year ago.  For the year of 2013, net loan recoveries were 0.03% of average loans outstanding, compared to net charge offs of 0.35% for 2012.  The provision for loan losses was $400,000 for the current quarter and was a negative provision of

$117,000 year to date, versus a provision for loan losses of $1.5 million and $6.9 million for the three month and annual periods ended December 31, 2012, respectively.

Non-interest expense increased 11.7% to $12.5 million for the current quarter compared to $11.2 million for the fourth quarter 2012.  The current quarter includes approximately $160,000 of merger expenses and an impairment charge on certain pooled trust preferred securities of approximately $300,000 resulting from the Volcker rule. During 2013, the Company added commercial lenders, other key positions and opened two de novo banking offices, which accounts for the remaining modest increase in expenses during the fourth quarter of 2013 as compared to the 2012 fourth quarter. For the current quarter versus the third quarter 2013, non-interest expense increased $1.4 million due to the mentioned items and accruals related to performance compensation.  On an annual basis, non interest expense remained relatively flat at $43.8 million for the 2013 year compared to $43.5 million for the year ended 2012.  In November, the bank completed its branch profitability analysis and decided to close two low performing offices during the 1st quarter of 2014.

Mortgage Banking Segment Income Review

For the current quarter ended December 31, 2013, George Mason Mortgage, the Company’s mortgage banking subsidiary, reported a net loss of $1.6 million versus net income of $3.7 million for the year ago quarter. For the comparable 2013 and 2012 annual periods, the Company reported a net loss of $5.2 million versus net income of $17.6 million, respectively.

Non-interest income, which is reported net of commissions and incentives, was $4.8 million in the current quarter versus $441,000 last quarter and $10.9 million for the fourth quarter of 2012. For the comparable annual periods ended December 31, 2013 and 2012, noninterest income for the mortgage banking segment was $24.8 million versus $54.8 million, respectively.  The SAB 109 accounting adjustment, as reported in Table 4, resulted in a material decrease of $30.8 million in reported gains from mortgage banking activities in fiscal 2013 versus 2012.  George Mason originators produced $4.2 billion of closed loans in 2013 versus $4.1 billion in 2012.  Of this amount, purchase money represents $2.8 billion of closed loans in 2013 versus $1.5 billion in 2012.

For the current quarter, non-interest expense decreased to $8.0 million compared to $8.8 million for the prior quarter. For the annual periods ended December 31, 2013 and 2012, expenses increased to $35.2 million from $29.5 million, respectively. The increase in non-interest expense is attributable to the expansion of the Company’s mortgage banking operations during the first six months of the year.  The mortgage banking segment currently has 192 loan officers, up from 160 officers a year ago.  Over the past year, the Company added 4 offices and now operates in 20 mortgage banking locations.

Mortgage banking originations and related revenues were significantly impacted by the increase in interest rates during the last half of 2013.  Although the average margin on loans sold to investors increased during the current quarter to 2.24% from 1.91% for the third quarter of 2013, overall loan origination volume continued to decline. As previously discussed, certain cost control programs and margin enhancement measures were enacted as a result of the current

operating environment.  The impact of these actions began to be realized during the current quarter.  The Company continues to take action to return the mortgage banking segment to profitability based upon market conditions and its projected production volumes.

Review of Balance Sheet

At December 31, 2013, total assets of the Company decreased $143.7 million to $2.90 billion, a decrease of 5% from total assets of $3.04 billion at December 31, 2012. Loans held for investment grew 13% to $2.04 billion at December 31, 2013, from $1.80 billion at December 31, 2012.  During this period, the Bank’s investment portfolio increased to $360.0 million compared to $286.4 million a year ago. Loans held for sale decreased to $374.0 million compared to $785.8 million at December 31, 2012.  The decrease in total assets is primarily the result of the $411.8 million decrease in mortgage loans held for sale, which was partially offset by a $236.7 million increase in loans held for investment and a $73.3 million increase in total investment securities.

Total deposits were $2.06 billion, a decrease of $185.0 million, or 8%, compared to December 31, 2012.  The Company uses short term brokered CDs as a source of funding for its mortgage loans held for sale portfolio.  As these assets have declined, there has been an associated reduction of its brokered CD portfolio from $616.6 million a year ago to $282.0 million at December 31, 2013. However, demand deposits and interest checking deposits grew $132.4 million over the past year, increasing 19% and reflecting the success of the Bank’s strategic initiatives to generate core deposits.

Dividend Announcement

The Company today also announced that its Board of Directors has declared an increase of $0.02 to its quarterly cash dividend.  A dividend of $0.08 per share will be paid on February 24, 2014 to shareholders of record as of the close of business on February 6, 2014.

Mortgage Revenue Recognition Impact of SAB 109 (Written Loan Commitments Recorded at Fair Value Through Earnings)

For the Three Months and Years Ended December 31, 2013 and 2012

(Dollars in thousands, except share and per share data)

**

Per the accounting guidance set forth by SEC Staff Accounting Bulleting (SAB) #109 regarding mortgage lending activities, the fair value of a “locked” commitment, or an unrealized gain, is recognized in income on the day of the locked commitment (LC). As a result of this revenue recognition, the unrealized gains then become part of the basis of the ensuing loan held for sale (LHFS) when the loan is closed. When the loan is sold to investors, the “price” received is equal to the basis of the loan held for sale, and there is no gain or loss recognized. At any point in time (e.g. quarter end) the fair value of the LCs and the premium to the par value of LHFS represent unrealized gains that have been recognized in income, either in the current period or prior periods. This accounting creates a mismatch between the income recognition on loan production and expense recognition for those same loans, which is discussed below.

In accordance with accounting rules (formally FAS 91), direct (e.g. commissions) and indirect loan expenses associated with originating, underwriting and closing loans are deferred and amortized over the life of the loan. In mortgage banking, this results in the mentioned expenses being recognized at the time of investor purchase of the loan (i.e. loan sale date) which often occurs in the quarter subsequent to the original LC and creates a mismatch in the timing of the revenue and expense. These expenses are “netted” from the gain on sale from mortgage banking activities, which is included in non-interest income.
