Loan Growth and Interest Recoveries Drive Earnings

EUGENE, Ore., October 16, 2013 – Pacific Continental Corporation (Nasdaq: PCBK), the holding company of Pacific Continental Bank, today reported financial results for the third quarter 2013.

Recent highlights:

Net income

Net income for third quarter 2013 was $3.9 million or $0.22 per diluted share compared to net income of $3.4 million or $0.19 per diluted share in third quarter 2012. Included in the period were loan recoveries and interest recoveries, on two loans, totaling $613 thousand and $982 thousand, respectively. Also included in the period was a $728 thousand write down on a commercial land development property held in other real estate. Return on average assets, average book equity, and average tangible equity were 1.09%, 8.77%, and 10.12%, respectively, in third quarter 2013, compared to 1.03%, 7.52%, and 8.56% for the same quarter last year.

“We are pleased with the recent quarter and year-to-date results that reflect the excellent work of all departments within the bank,” said Hal Brown, chief executive officer. “Loan and deposit growth strongly supported the board’s decision to increase our regular dividend,” added Brown.

Loan growth

Outstanding gross loans at September 30, 2013, were $978.7 million, up $18.2 million over the prior quarter end and up $141.7 million from third quarter 2012. After removing the loans acquired in the Century Bank transaction, organic loan growth for the first nine months of 2013 was $59.7 million representing an annualized growth rate of 9.15%. Loan growth for the third quarter was primarily centered in construction lending and commercial loans. At September 30, 2013, loans to dental professionals totaled $303.9 million representing 31.05% of the total loan portfolio. Outstanding loans to dental professionals grew 12.23% during the first nine months of 2013 and 23.74% over September 30, 2012. National dental lending at September 30, 2013, totaled $122.5 million, up $20.2 million during the third quarter.

“We are pleased to report that the sustained loan growth has been attributable to long standing commercial clients who are now taking advantage of the improving economy, combined with our strong health care referral network and concerted calling efforts on the part of our bankers,” said Roger Busse, president and chief operating officer. “While competition for loans continues, we anticipate that our strong loan pipelines should lead to continued growth,” added Busse.

Core deposit growth accelerates

Period-end Company-defined core deposits at September 30, 2013, were $1.0 billion and represented an increase of $56.9 million from the prior quarter end, reflecting the typical seasonal growth pattern during the last half of the year. At period-end September 30, 2013, noninterest-bearing demand deposits totaled $379.6 million and represented 37.37% of core deposits. Century Bank core deposit retention remained strong with September 30, 2013 balances at 94.31% of the February 1, 2013 acquisition total.

Net interest margin

The third quarter 2013 net interest margin, on a tax equivalent basis, was 4.58%, representing a linked-quarter increase of 38 basis points from second quarter 2013, and an increase of 42 basis points from third quarter 2012. Included in the third quarter net interest margin was $982 thousand of interest recoveries, which contributed 30 basis points to the third quarter margin. In addition, the accretion of the Century Bank loan fair value market adjustment positively impacted the net interest margin by 5 basis points.

Classified assets, provisioning and loan statistics

At September 30, 2013, classified assets totaled $54.5 million and represented 30.25% of regulatory capital, compared to $56.1 million and 31.18% of regulatory capital at December 31, 2012. Classified asset levels were temporarily increased by $5.8 million as a result of the Century Bank acquisition. Third quarter 2013 classified assets were lower than pre-acquisition levels.

Nonperforming assets, a subcategory of classified assets, totaled $21.8 million at September 30, 2013, or 1.50% of total assets, a decrease from December 31, 2012, and September 30, 2012, ratios of 1.92% and 2.14%, respectively. Nonperforming assets were comprised of $5.2 million of nonperforming loans, net of government guarantees, and $16.6 million in other real estate owned. Loans past-due 30-89 days were 0.37% of total loans at September 30, 2013, compared to 0.30% at December 31, 2012. This is the seventeenth consecutive quarter in which this ratio was near or below one percent.

Classified dental loans totaled 2.16% of total dental loans with net charge offs of $377 thousand through September 30, 2013. National dental lending statistics remain positive with no loans past due, and 0.60% of the national dental lending portfolio considered classified.

“Principal and interest recoveries of more than $1.7 million during the quarter reflected the successful efforts of our legal and special assets teams who diligently work on problem loan collection well after loan charge offs occurred,” said Casey Hogan, executive vice president and chief credit officer.

The Company made no provision for loan losses during the third quarter 2013, with quarter to date net recoveries of $499 thousand. The allowance for loan losses as a percentage of outstanding loans at September 30, 2013, was 1.72% compared to 1.88% at December 31, 2012, and 1.95% at September 30, 2012. The allowance for loan losses as a percentage of total nonperforming loans, net of government guarantees, improved to 325.94% at September 30, 2013, from 167.87% reported one year ago, reflecting both a reduction in nonperforming loans and an overall general improvement in the quality of the loan portfolio.

Capital levels

The Company’s capital ratios continued to be well above the minimum FDIC “well-capitalized” designated levels. At September 30, 2013, the Company’s Tier 1 leverage ratio, Tier 1 risk-based capital ratio, and Total risk-based capital ratios were 11.56%, 15.16% and 16.42%, respectively, as compared to 12.53%, 17.37% and 18.62% at September 30, 2012, reflecting improved capital leverage. The FDIC’s minimum “well-capitalized” ratios are 5.00%, 6.00% and 10.00%, respectively.

In February 2013, the Company’s board of directors authorized a stock repurchase plan. The plan authorizes the repurchase up to 892,000 shares or five percent of the Company’s outstanding shares. The plan commenced on April 1, 2013, with purchases to occur over a 12-month period. No shares were repurchased under the plan.

Noninterest income and expense

Noninterest income for the third quarter was $1.4 million, up $32 thousand over third quarter 2012, reflecting a small increase in both service charge and bankcard income. Noninterest expense in third quarter 2013 was up $1.7 million over third quarter 2012, with a portion of the increase centered in other real estate expense, which includes the effects of the $728 thousand third quarter other real estate write down. In addition, compensation and business development expenses were up, reflecting the addition of business development personnel who have increased calling efforts during 2013 as evidenced by the Bank’s loan growth. The third quarter efficiency ratio was 63.82% compared to 62.70% for third quarter 2012.
