NEWS RELEASE

CARDINAL ANNOUNCES FIRST QUARTER EARNINGS;

SUCCESSFUL INTEGRATION OF UNITED FINANCIAL BANKING COMPANIES

Cardinal Financial Corporation (NASDAQ: CFNL) (the “Company”) today announced quarterly earnings of $4.3 million, or $0.13 per diluted share, for the period ended March 31, 2014.  This compares to earnings of $7.2 million, or $0.23 per diluted share, for the first quarter of last year.  On January 15th, the Company acquired United Financial Banking Companies, Inc. (UFBC), and during the quarter, the Company incurred $3.2 million of expenses related to this merger and to the conversion of back office systems.  The after-tax impact of these expenses was $0.07 per share. Without these expenses, the Company had adjusted quarterly earnings of $6.5 million, or $0.20 per share.

Selected Highlights

·                  During the quarter, loans held for investment organically grew approximately $67 million, or over 13% annualized.  This is the fourth consecutive quarter of annualized double digit loan growth.

·                  Asset quality remains excellent.  Nonperforming loans were 0.16% of total assets, and the Company had net loan charge offs of 0.12% of average loans outstanding.  The Company had $0 real estate owned at March 31, 2014, and $4.9 million of non-accruing loans.

·                  The Company integrated UFBC’s systems in March.  Quarterly income and expenses include the operations of the former UFBC since the January 15, 2014 combination.

·                  Despite refinance volume slowing to 18% of originations and difficult winter weather conditions that impacted home buying, late quarter activity resulted in mortgage loan

applications increasing to $961 million for the current quarter, up slightly from $886 million for the previous quarter. Mortgage bank segment net loss decreased to $167,000 compared to $1.6 million for the previous quarter and $1.1 million for the first quarter 2013.

·                  All capital ratios exceed the requirements of banking regulators to be considered well-capitalized.  Tangible common equity capital (TCE) as a percentage of total assets was 9.88% at March 31, 2014.

United Financial Banking Companies Acquisition

On January 15, 2014, the Company completed its previously announced acquisition of UFBC and its primary subsidiary, The Business Bank.  In connection with the transaction, 1,616,882 shares of the Company’s common stock were issued to UFBC’s shareholders, along with $26.8 million in cash.   The Company added $329 million of total assets to its balance sheet, including $238 million of loans, net of negative $3.9 million of fair value adjustments, and $295 million of deposits, including a positive $1.2 million fair value adjustment to the CD portfolio.  Additionally, the Company recorded $24.7 million of goodwill and $2.7 million of core deposit intangibles.  During the quarter, the Company incurred legal and accounting costs, contract termination expenses, system conversion and integration expenses, plus employee retention and severance payments related to the acquisition.  These expenses totaled $3.2 million.  Total acquisition costs were initially estimated to be a range of $6.8 to $7.0 million and are not expected to exceed that level.  We expect remaining expenses to be incurred in the second quarter of 2014.  Our expectation of cost savings associated with the acquisition has increased to 50%, up from 40% that was originally reported.   Four banking offices will be consolidated in the second quarter and another two by year end.

Review of Balance Sheet

At March 31, 2014, total assets of the Company were $3.14 billion, an increase of 12% from total assets of $2.82 billion at March 31, 2013. Loans held for investment grew $563 million, or 32%, to $2.35 billion from $1.78 billion a year ago.  Excluding the acquisition of UFBC, loans grew approximately $325 million, or 18% annualized.  Loans held for sale decreased to $265 million compared to $535 million at March 31, 2013. Although brokered CD balances decreased $56 million, overall deposit balances increased $288 million to $2.38 billion at March 31, 2014 versus $2.09 billion at March 31, 2013.  Demand deposits (DDA) increased to $534 million and now represent 22.5% of total deposits.  Organic DDA growth was $82 million, an increase of 23% from a year ago.

For the current quarter, organic loan growth was approximately $67 million, or over 13% annualized.  Organic DDA growth was $10 million, representing a 9.3% annualized increase since year end 2013.

Commercial Banking Segment Income Review

For the current quarter ended March 31, 2014, net income for the commercial banking segment was $5.5 million.  Before the merger and conversion expenses incurred during the current quarter, net income was $7.4 million compared to $9.1 million for the quarter ended March 31, 2013.  Included in the current period results is a provision for loan losses of $1.9 million, versus a negative provision for loan losses of $542,000 that was recorded during the same quarter of 2013.  The increase to the provision for loan loss expense for the current quarter resulted from modest charge offs plus appropriately adding to the allowance for loan growth.

Net interest income for the current quarter was $25.2 million versus $22.4 million for the year ago quarter.  The Company’s tax equivalent net interest margin increased to 3.64% from 3.35% for the same period of last year.  The contribution of the assets and liabilities from UFBC added approximately $2.3 million to net interest income and 0.01% to the margin for the current quarter.

Comparing the current quarter to the same quarter of 2013, the average balance of loans held for sale decreased $278 million and the average loans held for investment balances increased $468 million. The average balance of investments grew $97 million, and the yield on total interest earning assets increased to 4.34% from 4.18%.  Over this same period, average deposit balances increased $50 million and the average balance of other borrowed funds increased $88 million.  The average cost of interest bearing liabilities decreased to 0.96% from 1.08%. The acquisition of UFBC added approximately $200 million to average loan balances and approximately $240 million to average deposit balances, and the yield on loans was enhanced approximately 0.06% while the overall cost of funds decreased by approximately 0.03%.

The allowance for loan losses decreased to 1.24% of loans outstanding at March 31, 2014 from 1.37% at December 31, 2013.  This ratio decrease is primarily the result of the addition of $238 million of acquired loans. The allowance for loan losses on the Company’s legacy portfolio was 1.36% of loans outstanding at quarter end 2014.  The Company’s nonperforming assets were 0.16% of total assets at March 31, 2014 compared to 0.08% at December 31, 2013 and 0.20% at March 31, 2013.  For the current quarter, there were modest net charge offs equal to 0.12% of average loans outstanding, compared to net recoveries of 0.03% for the previous quarter and net recoveries of 0.07% for the year ago quarter.

Non-interest income was $932,000 for the current quarter compared to $794,000 for the year ago quarter ended March 31, 2013.  Deposit fees increased to $535,000, or 7%, from the year ago quarter.  The UFBC transaction added approximately $134,000 to non-interest income for the first quarter 2014.

Non-interest expense was $15.8 million for the current quarter versus $10.1 million for the year ago quarter ended March 31, 2013.  Before the merger and conversion expenses mentioned above, non-interest expense was $13.0 million, and the bank’s efficiency ratio was 49.8%.  Approximately $1.5 million of the expense increase from the year ago quarter is attributable to expenses associated with the former UFBC.  The Company also incurred $200,000 of intangible expense amortization as a result of the transaction.  Another $360,000 of the expense increase resulted from the Company adding two branches in 2013.  The remaining expense increase was incurred to support the Company’s business initiatives.  During the first quarter of 2014, the

Company closed two underperforming branches which are expected to provide $700,000 in future annual cost savings.

Mortgage Banking Segment Income Review

For the current quarter ended March 31, 2014, net loss for the mortgage banking segment was $167,000 versus a net loss of $1.1 million for the quarter ended March 31, 2013, and a net loss of $1.6 million for the previous quarter ended December 31, 2013.

Non-interest income, which is reported net of commissions, incentives and certain salary expenses, was $7.4 million versus $7.1 million in the same prior year quarter and $4.8 million for the last quarter of 2013.  Net gains from mortgage banking activities were $7.4 million for the most recent quarter versus $6.3 million for the year ago quarter and $4.2 million for the last quarter of 2013.  The net gains from mortgage banking activities for the current quarter increased $3.6 million as a result of the Staff Accounting Bulletin (SAB) 109. For the year ago quarter and the previous quarter, the SAB 109 adjustments were decreases of $4.7 million, and $2.3 million, respectively, in unrealized gains that impacted reported income.

Loan applications totaled $961 million during the first quarter of 2014, up slightly from the previous quarter as origination trends picked up late in the quarter to offset lower refinance activity and the impact of several winter weather events.  January, February and March applications totaled $285 million, $299 million and $376 million, respectively.  During the quarter, closed loans were $551 million and loans sold to investors totaled $562 million, versus $797 million and $758 million, respectively, for the previous quarter. The margin on loans sold to investors was 2.17%, 2.24% and 1.91% for the current and previous two quarters.

Other sources of non-interest income, including managed mortgage company affiliate fees and title insurance income, have become insignificant as George Mason has exited these lines of business.

For the current quarter, reported non-interest expense was $8.3 million.  This compares to $9.2 million for the quarter ended March 31, 2013 and to $8.0 million for the quarter ended December 31, 2013.  A portion of fixed salary expense associated with loan closings each quarter are accounted for as an offset to income, similar to commissions and incentives.  As loan closings declined during the current quarter, the salary expense classified as contra-revenue declined to $1.8 million, versus $2.4 million for the previous quarter and $3.4 million for the third quarter of 2013.  Without the reclassification of these salary expenses, core non-interest expense declined to $10.1 million for the current quarter, versus $10.4 million and $12.2 million for the previous two quarters, respectively.  For these same periods, core salary and benefit expense was $6.2 million, $6.4 million and $7.6 million.  The decrease is a direct result of a 24% reduction in the non production workforce since last September. First quarter salary and benefit expenses included $288,000 of seasonally higher payroll taxes and retirement benefits, compared to the previous quarter ended December 31, 2013.

The Company is continuing to take actions to return its mortgage banking segment to meaningful profitability with each expense category being monitored, analyzed and measured in relation to production expectations.

Capital & Dividend Announcement

Subsequent to the acquisition of UFBC, the Company remains in excess of well capitalized levels.  The tier 1 capital ratio 10.72% and the total risk based capital ratio is 11.71%.  Because of its continued capital strength, the Company today also announced that its Board of Directors has declared another dividend of $0.08 per share that will be paid on May 23, 2014 to shareholders of record as of the close of business on May 8, 2014.

MANAGEMENT COMMENTS

Bernard H. Clineburg, Chairman and Chief Executive Officer of the Company, said:

“The first quarter was highlighted by the completion of the acquisition and consolidation of UFBC.  Our team worked diligently to complete the conversion in six months and continues to create further revenue opportunities and operating efficiencies.  Since our September 9th, 2013 announcement, we saw both the UFBC loan and deposit balances increase, attesting to our successful integration process and the acceptance of the Cardinal brand.  Not to be overlooked is our organic commercial loan and deposit growth, which continued to be strong as we attracted new clients and expanded existing relationships.  We are pleased with the momentum of our purchase money activity and the progress toward right-sizing our mortgage banking operations.

As always, we will continue to concentrate on gaining profitable market share, either through de novo expansion or acquisition, which will increase our franchise value.  We remain committed to building and maintaining a strong financial services company for our shareholders, employees, clients and the communities we serve.”

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

Net Income Reconciliation for the Impact of Merger and Acquisition Expenses and SAB 109

**

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.
