FOR IMMEDIATE RELEASE

UNIVEST CORPORATION OF PENNSYLVANIA – UNIVEST

BANK AND TRUST CO. – REPORTS THIRD QUARTER EARNINGS

SOUDERTON, Pa., October 23, 2013 – Univest Corporation of Pennsylvania (“Univest”) (NASDAQ: UVSP), parent company of Univest Bank and Trust Co. and its insurance, investments and equipment financing subsidiaries, today announced financial results for the quarter ended September 30, 2013. Univest reported net income of $6.0 million or $0.36 diluted earnings per share for the quarter ended September 30, 2013, a 5% increase over the reported net income of $5.8 million or $0.34 diluted earnings per share for the quarter ended September 30, 2012. Net income for the nine months ended September 30, 2013 was $16.3 million or $0.97 diluted earnings per share, a 3% increase in net income compared to $15.8 million or $0.94 diluted earnings per share for the comparable period in the prior year.

Loans

Gross loans and leases increased $44.4 million or 3% from December 31, 2012 and $56.7 million or 4% from September 30, 2012. The growth in loans from the prior year-end and comparable quarter in 2012 occurred in commercial and residential real estate loans and equipment financing. While the longer-term economic outlook remains positive, short-term uncertainty over the direction of fiscal and monetary policy is restraining overall credit demand and the utilization of available credit lines by both businesses and consumers.

Deposits

Total deposits were up $23.7 million from December 31, 2012, mainly due to a product change for existing business and municipal customers which resulted in approximately $68.1 million of customer repurchase agreements, classified as borrowings, being transferred to interest-bearing demand deposits. This transfer was partially offset by a decrease in time deposits of $41.7 million. Total deposits grew $111.1 million from September 30, 2012, primarily due to an increase in demand deposits.

Net Interest Income and Margin

Net interest income increased $300 thousand or 2% to $18.3 million in the third quarter of 2013 compared to the third quarter of 2012. The net interest margin on a tax-equivalent basis for the third quarter of 2013 was 3.84%, consistent with the second quarter of 2013 and the third quarter of 2012. While the tax-equivalent yield on average interest-earning assets declined 16 basis points for the third quarter of 2013 compared to the same period in the prior year, the rate on interest-bearing liabilities was also down 20 basis points compared to the same period. The decline in rate on interest-bearing liabilities was attributable to Univest’s decision to redeem its trust preferred securities and terminate the related interest rate swap and an overall decline in rates paid on time and interest bearing deposits.

Net interest income of $54.4 million for the nine months ended September 30, 2013 was consistent with the same period in 2012. The net interest margin on a tax-equivalent basis for the nine months ended September 30, 2013 was 3.84% compared to 3.92% for the nine months ended September 30, 2012. The decline in the year-to-date net interest margin from the comparable period in the prior year was primarily due to the re-investment of maturing and called investment securities into lower yielding investments. In addition, lower rates on commercial and residential real estate loans due to re-pricing and the competitive environment contributed to the decline. Favorable re-pricing of savings accounts, customer repurchase agreements and certificates of deposit – along with maturities of higher yielding certificates of deposit – partially offset the decline in the year-to-date net interest margin.

Non-Interest Income

Non-interest income for the quarter ended September 30, 2013 was $13.2 million, an increase of $2.3 million or 22% from the comparable period in the prior year. Non-interest income for the nine months ended September 30, 2013 was $35.7 million, an increase of $5.8 million or 19% from the comparable period in the prior year. Insurance commission and fee income increased $384 thousand for the quarter and $1.4 million for the nine months ended September 30, 2013, primarily a result of the acquisitions of the John T. Fretz Insurance Agency, Inc. on May 1, 2013 and Javers Group on May 31, 2012. Investment advisory commission and fee income increased $186 thousand for the quarter and $1.1 million for the nine months ended September 30, 2013 as assets under supervision increased 16% over September 2012. The net gain on sales of securities increased $1.4 million for the quarter and $2.7 million for the nine months ended September, 30 2013. The net gain on sales of other real estate owned was $198 thousand for the quarter and $450 thousand for the nine months ended September 30, 2013. This compares favorably to a net loss on sales and write-downs of $621 thousand and $1.7 million, respectively, for the comparable periods in the prior year. Excess proceeds from bank owned life insurance death benefits of $1.1 million were recognized during the third quarter of 2013. On a year-to-date basis, $1.1 million in excess proceeds from bank owned life insurance death benefits were recognized in 2013 compared to $989 thousand for the same period in the prior year.

These favorable increases were partially offset by a $1.9 million loss on the termination of an interest rate swap during the second quarter of 2013, which was used as a hedge of trust preferred securities. In addition, the net gain on mortgage banking activities decreased $1.2 million for the quarter and $470 thousand for the nine months ended September 30, 2013. The increase in interest rates during the second quarter of 2013 contributed to a significant decline in refinance activity, reduced demand for new home purchases and lowered gain on sale margins. Mortgage banking originations declined 39% in the third quarter of 2013 from the second quarter of 2013 and the third quarter of 2012.

Non-Interest Expense

Non-interest expense for the third quarter of 2013 was $20.0 million, an increase of $930 thousand or 5% compared to the third quarter of 2012. Salaries and benefits expense increased $817 thousand primarily attributable to the Fretz acquisition and performance-based salary and incentive increases. Commission expense increased $142 thousand mainly due to increased production activity and revenues generated in our equipment finance, investment and insurance businesses partially offset by a decline in mortgage banking commissions.

Non-interest expense for the nine months ended September 30, 2013 was $59.5 million, an increase of $3.0 million or 5% from the comparable period in the prior year. Salaries and benefits expense increased $795 thousand primarily attributable to the Fretz and Javers acquisitions and performance-based salary and incentive increases. Commission expense increased $1.6 million mainly due to increased production activity and revenues generated in our equipment finance, investment and insurance businesses. Additionally, non-interest expense increased due to restructuring charges of $539 thousand recognized during the first quarter of 2013.

Asset Quality and Provision for Loan and Lease Losses

Non-accrual loans and leases, including non-accrual troubled debt restructured loans, decreased to $24.0 million at September 30, 2013, from $32.1 million at December 31, 2012 and $30.5 million at September 30, 2012. The decrease in non-accrual loans from December 31, 2012 was mainly due to charge-offs, foreclosures and pay-downs exceeding additions to non-accrual loans. Net loan and lease charge-offs were $4.0 million during the third quarter of 2013, down from $5.6 million for the third quarter of 2012.

Non-accrual loans and leases as a percentage of total loans and leases (held for investment and nonaccrual loans held for sale) were 1.57% at September 30, 2013, compared to 2.17% at December 31, 2012 and 2.07% at September 30, 2012.

The provision for loan and lease losses was $4.1 million for the third quarter of 2013, compared to $2.2 million for the quarter ended September 30, 2012. The provision for loan and lease losses was $9.6 million for the nine months ended September 30, 2013, compared to $7.7 million for the same period in the prior year. The increase in the loan and lease provision for both the third quarter of 2013 and nine months ended September 30, 2013 was primarily attributable to the intra-dependency of collateral and updated assessments of residential building lots securing loans to a common borrower. The allowance for loan and lease losses as a percentage of loans and leases held for investment was 1.63% at September 30, 2013, compared to 1.67% at December 31, 2012 and 1.84% at September 30, 2012. The allowance for loan and lease losses to nonaccrual loans and leases held for investment equaled 103.59% at September 30, 2013, compared to 77.01% at December 31, 2012 and 97.03% at September 30, 2012.

Capital

Univest continues to remain well-capitalized at September 30, 2013. Total risk-based capital at September 30, 2013 was 13.73%, well in excess of the regulatory minimum for well capitalized status of 10%.

Share Repurchase Plans

During the quarter, Univest repurchased 395,000 shares of common stock at a cost of $7.4 million under its 2007 Board approved share repurchase program. At September 30, 2013, this share repurchase plan was substantially completed. Total shares outstanding at September 30, 2013 were 16,288,597.

On October 23, 2013, Univest’s Board of Directors approved a new share repurchase program for the repurchase of up to 800,000 shares, or approximately 5% of the shares outstanding.

Dividend

On August 16, 2013, Univest declared a quarterly cash dividend of $0.20 per share, payable on October 1, 2013. This represented a 4.21% annualized yield based on the closing price of Univest’s stock on the date the dividend was paid.
