Pacific Continental Corporation Reports Fourth Quarter and Full Year 2012 Results

Loan Growth, Deposit Growth and Credit Quality Improvement Drive Results

EUGENE, Ore., January 16, 2013 — Pacific Continental Corporation (Nasdaq: PCBK), the holding company of Pacific Continental Bank, today reported financial results for the fourth quarter and full year 2012.

Recent highlights:

Net Income

Net income for fourth quarter 2012 was $3.4 million or $0.19 per diluted share. Fourth quarter 2012 results included $203 thousand of merger expenses related to the Company’s recently announced acquisition of Century Bank in Eugene, Oregon. Return on average assets and return on average tangible equity for fourth quarter 2012 were 0.99% and 8.33%, respectively.

Net income for the year 2012 was $12.7 million, $0.69 per diluted share, and increased $7,312 million or 136.9% over the $5,341 million, $0.29 per diluted share, reported for 2011. Return on average assets and return on average tangible equity for 2012 were 0.96% and 7.94%, respectively, compared to 0.44% and 3.45% in 2011.

“Our current quarter and full year results and recent acquisition announcement clearly demonstrate the successful execution of strategic initiatives,” said Hal Brown, chief executive officer. “Accelerating loan and deposit growth, plus continued credit quality improvement, suggest consistent and strengthening financial performance that supports the board’s decision to increase the cash dividend,” added Brown.

Loan and core deposit growth accelerates

Outstanding gross loans at December 31, 2012, were $871.3 million, up $34.3 million during the fourth quarter. Loan growth during the fourth quarter 2012 represented an annualized growth rate of 16.3%, and was primarily centered in construction and commercial loans. Growth in commercial loans was especially strong, increasing 6.1% during the fourth quarter and 19.4% over year-end 2011. The Bank continued to enjoy success in lending to health care professionals. Dental practice loans, in particular, grew 10.3% during the fourth quarter and 29.9% over December 31, 2011. Contributing to the growth in dental lending was the Company’s expansion of out-of-market dental loans. Out-of-market dental loans at December 31, 2012, were $78.9 million, up $10.5 million during the quarter and up $36.5 million over December 31, 2011.

December 31, 2012, period-end Company-defined core deposits totaled $938.6 million, an increase of $56.0 million over the end of third quarter 2012 and up $52.8 million over December 31, 2011. During 2012, the Company experienced a more typical seasonal core deposit pattern with deposit outflows occurring during the first half of the year followed by growth in core deposits during the second half of the year. As is also typical, at year-end there are approximately $20 million of temporary deposits that are expected to be withdrawn during the first quarter of 2013. At December 31, 2012, noninterest-bearing demand deposits totaled $329.8 million, an 18.4% increase from that of a year ago, and now represent 35.1% of total core deposits. Average core deposits, a measure that eliminates daily volatility, for the fourth quarter 2012 were $900.4 million, up $20.8 million over third quarter 2012.

“Loan and deposit pipelines strengthened throughout 2012 and resulted in significant growth during the fourth quarter,” said Roger Busse, president and chief operating officer. “The positive momentum we have generated in niche banking to health care professionals, nonprofit organizations, and community based businesses, combined with our focus on client relationships and service, suggest excellent prospects for growth during 2013,” added Busse.

Classified assets, provisioning and loan statistics

Classified assets continued a two-year trend of decline, and at December 31, 2012, totaled 31.2% of capital, a decline from the 38.96% reported at December 31, 2011. Nonperforming assets, a subcategory of classified assets, totaled $26.4 million at December 31, 2012, or 1.92% of total assets, a decrease from the December 31, 2011, ratio of 2.92%.

Loans past-due 30-89 days were 0.30% of total loans at December 31, 2012, compared to 0.41% of total loans at December 31, 2011. This is the fourteenth consecutive quarter in which this ratio was near or below one percent.

“We continued to make solid progress in reducing our level of problem assets during 2012 and our pending resolutions and collection activities suggest this trend should continue in 2013,” said Casey Hogan, executive vice president and chief credit officer. “The diligence of our Credit Administration staff is apparent as we recorded net recoveries for the second consecutive quarter,” added Hogan.

The Company recorded no provision for loan losses in the fourth quarter of 2012, reflecting improved credit quality and recoveries recorded during the quarter. During the fourth quarter 2012, the Company

had net loan recoveries of $62 thousand compared to net recoveries of $108 thousand in third quarter 2012. For the year 2012, the Company recorded net loan charge offs of $496 thousand or an annualized 0.06% of average loans.

The allowance for loan losses as a percentage of outstanding loans at December 31, 2012, was 1.88% compared to 1.82% at December 31, 2011.

Capital management

In February 2012, the Company’s board of directors authorized the repurchase of up to five percent of the Company’s shares issued and outstanding, or approximately 922,000 shares, with the purchases to take place over 12 months. During the fourth quarter 2012, the Company repurchased 65,100 shares at a weighted average price of $9.04 per share including commissions. Since the inception of the repurchase plan, the Company has repurchased 641,637 shares at a weighted average price of $8.85 per share. Share repurchases and regular and special cash dividends totaling $0.31 per share during 2012 combined to keep capital levels relatively unchanged from prior year-end, a capital leverage strategy that is likely to continue in 2013.

The Company’s capital ratios continue to be well above the minimum FDIC “well-capitalized” designated levels. At December 31, 2012, the Company’s Tier 1 leverage ratio, Tier 1 risk-based capital ratio, and Total risk-based capital ratio were 12.33%, 16.90% and 18.15%, respectively, as compared to 13.09%, 17.97% and 19.22% at December 31, 2011. The FDIC’s current minimum “well-capitalized” designation ratios are 5.00%, 6.00% and 10.00%, respectively.

Net interest margin

The fourth quarter 2012 net interest margin was 4.11%, a decline of 5 and 48 basis points from the net interest margins reported for third quarter 2012 and fourth quarter 2011, respectively. For the year 2012, the net interest margin was 4.24%, down 37 basis points from 2011. The contraction in the net interest margin was due to lower yields on the Company’s loan and securities portfolio. Loan yields continued to contract during the fourth quarter 2012 when compared to the prior quarter and prior year as new loan production in this historically low interest rate environment was booked at yields lower than the average yield on the existing portfolio. The yield on the securities portfolio was impacted by low long-term interest rates that accelerated prepayments on the agency mortgage-backed segment of the portfolio, thus increasing the amortization of premiums and reinvestment of cash flows from the portfolio at lower rates than the average yield on the portfolio.

Noninterest income and expense

Fourth quarter noninterest income was $1.4 million, relatively unchanged from the prior quarter and up $65 thousand from the fourth quarter last year. For the year 2012, noninterest income was $5.7 million compared to $5.9 million in 2011. Noninterest income in 2011 included $884 thousand of gains on the sale of securities. Excluding the 2011 gains on the sale of securities, 2012 noninterest income was up 15.2% over prior year.

Noninterest expense in fourth quarter 2012 was up $193 thousand over the prior quarter and declined by $876 thousand, or 9.0%, from fourth quarter 2011. For the year 2012 noninterest expense of $35.1 million was down $2.0 million or 5.3% from prior year. The fourth quarter 2012 increase in noninterest expense compared to the prior quarter was primarily due to merger related expenses of $203 thousand. The decline in full year 2012 noninterest expense from last year was due to reductions in FDIC insurance

assessments, other real estate expense, and costs, such as legal fees related to collection of problem assets. A portion of the decline in these three categories was offset by an increase in personnel expense. For 2012, the Company’s efficiency ratio was 62.9%, a decline from the 2011 efficiency ratio of 65.0%, reflecting continued expense control during a time of compressed interest margins.
