Pacific Continental Corporation Reports Fourth Quarter and Full Year 2014 Results

Loan growth, deposit growth and efficiency drive record 2014 earnings

EUGENE, Ore., January 21, 2015 — Pacific Continental Corporation (Nasdaq: PCBK), the holding company of Pacific Continental Bank, today reported financial results for the fourth quarter and full year 2014.

Recent highlights:

Net income

Net income for fourth quarter 2014 was $3.6 million or $0.20 per diluted share compared to net income of $3.7 million or $0.20 per diluted share in fourth quarter 2013. Fourth quarter 2014 results included $470 thousand of merger expense related to the pending acquisition of Capital Pacific Bank that reduced net income in the current quarter by approximately $0.02 per share.

Net income for the full year 2014 was a record $16.0 million or $0.89 per diluted share, compared to net income of $13.8 million or $0.76 per diluted share for 2013. Excluding the $470 thousand of merger expense, net income for the year was $16.3 million or $0.91 per share. Return on average assets, average book equity, and average tangible equity were 1.09%, 8.83%, and 10.14%, respectively. The efficiency ratio for the full year 2014 improved to 59.41%.

“Our record earnings for 2014 reflect the efforts of every Pacific Continental employee and the successful execution of our business strategies,” said Roger Busse, chief executive officer. “We are optimistic our results will continue to improve during 2015 on an organic basis, and anticipate our pending acquisition of Capital Pacific Bank in Portland, Oregon will add to our financial performance during the year.”

Core deposits

Period-end Company-defined core deposits at December 31, 2014, were $1.11 billion, up $63.7 million from September 30, 2014, and were consistent with typical fourth quarter seasonal patterns. Outstanding core deposits at December 31, 2014 were up $120.5 million or 12.17% over December 31, 2013. Average core deposits, which removes daily volatility in balances, for the fourth quarter 2014 were $1.08 billion compared to $1.04 billion and $987.2 million for third quarter 2014 and fourth quarter 2013, respectively. At period-end December 31, 2014, noninterest-bearing demand deposits totaled $407.3 million and represented 36.67% of core deposits.

“We strongly believe that a stable and growing core deposit base provides long-term franchise and shareholder value,” said Casey Hogan, chief operating officer. “We continue to provide high levels of personal and technological service to our clients developing long-term deposit relationships to support our lending activities.”

Loans

Outstanding gross loans at December 31, 2014, were $1.05 billion, up $10.1 million from September 30, 2014 and up $51.2 million over December 31, 2013. Overall, loan growth during 2014 was primarily attributable to increased commercial and industrial lending and local real estate lending. Loans to dental professionals were relatively unchanged in fourth quarter 2014 from the previous quarter. During 2014, the Company continued to see expansion of its national dental lending, but experienced a decline in the more seasoned local dental portfolio due to normal principal payments. At December 31, 2014, loans to dental practitioners totaled $306.4 million and represented 29.29% of the loan portfolio compared to 29.65% and 30.89% of the loan portfolio at September 30, 2014 and December 31, 2013, respectively.

Credit quality and statistics

For the seventh consecutive quarter, the Company made no provision for loan losses, reflecting the credit quality of the loan portfolio. With the growth in the loan portfolio, the allowance for loan losses as a percentage of outstanding loans at December 31, 2014, declined to 1.50% compared to 1.60% at December 31, 2013. The allowance for loan losses as a percentage of nonperforming loans net of guarantees remained very strong at 786.17%. During the fourth quarter 2014, the Company recorded net loan charge offs totaling $85 thousand. For the full year 2014, net loan charge offs were $280 thousand, compared to net loan charge offs of $678 thousand in 2013.

At December 31, 2014, nonperforming assets, net of government guarantees, totaled $15.4 million, or 1.02% of total assets, compared to $21.0 million or 1.45% of total assets at December 31, 2013. Nonperforming assets at December 31, 2014 were comprised of $2.0 million of nonperforming loans, net of government guarantees, and $13.4 million in other real estate owned. Loans past-due 30-89 days were 0.15% of total loans at December 31, 2014, compared to 0.16% of total loans at September 30, 2014.

Net interest margin

The fourth quarter 2014 net interest margin averaged 4.24%, a decline of 4 basis points and 14 basis points from third quarter 2014 and fourth quarter 2013, respectively. The decline in the linked-quarter net interest margin was due to lower earning asset yields as the yield on both the loan and securities portfolio fell slightly. The decline in the current quarter net interest margin from last year of 14 basis points was due to nonrecurring interest income recoveries recorded in fourth quarter 2013. During the fourth quarter 2014, the net accretion of loan fair value marks was $90 thousand and positively impacted the net interest margin by 3 basis points.

Noninterest income and expense

Fourth quarter 2014 noninterest income was $1.3 million, up $121 thousand from third quarter 2014, and down $245 thousand from fourth quarter 2013. Fourth quarter 2014 noninterest income reflected increased merchant processing revenues resulting in the linked-quarter improvement. The decline in year-over-year noninterest income resulted from the outsourcing of merchant processing in the fourth quarter 2013. The outsourcing of merchant processing also eliminated related processing expense.

Noninterest expense in fourth quarter 2014 was up $649 thousand over third quarter 2014, primarily due to the $470 thousand of merger expense recorded during the current quarter. For the full year 2014, noninterest expense was down $3.0 million or 7.37%. When the merger related expenses are removed from noninterest expense, $470 thousand related to the Capital Pacific pending acquisition and $1.2 million related to the Century Bank acquisition, noninterest expense declined $2.2 million or 5.64% in 2014 compared to 2013. The decline in year-over-year noninterest expense was primarily due to lower legal fees, business development costs, and reductions in other real estate expense.

Capital levels

The Company’s capital ratios continued to be well above the minimum for the FDIC’s minimum “well-capitalized” designation. At December 31, 2014, the Company’s Tier 1 leverage ratio, Tier 1 risk-based capital ratio, and Total risk-based capital ratios were 11.33%, 14.48% and 15.73%, respectively, as compared to 11.49%, 14.90% and 16.15% at December 31, 2013. The FDIC’s minimum “well-capitalized” designation ratios for these metrics are 5.00%, 6.00% and 10.00%, respectively.

On May 6, 2014, the Company’s board of directors authorized the repurchase of up to five percent or approximately 893,000 of the Company’s outstanding shares with purchases to take place over the following 12 months. During the fourth quarter 2014, the Company did not repurchase any shares. During 2014, the Company repurchased 267,080 shares at a weighted average price of $13.48 per share.

Non-GAAP Financial Measures

In addition to results presented in accordance with generally accepted accounting principles (GAAP), this press release contains certain non-GAAP financial measures. The Company believes that such non-GAAP financial measures provide investors with information useful in understanding the Company’s financial performance; however, readers of this release are urged to review these non-GAAP financial measures in conjunction with the GAAP results as reported.

Financial measures such as tangible shareholders’ equity are considered non-GAAP measures. Management believes including non-GAAP measures along with GAAP measures provides investors with a broader understanding of capital adequacy. Tangible shareholders’ equity is calculated as total shareholders’ equity less goodwill and other intangible assets. Additionally, tangible assets are calculated as total assets less goodwill and other intangible assets.

The following table presents a reconciliation of ending shareholders’ equity (GAAP) to ending tangible shareholders’ equity (non-GAAP), and total assets (GAAP) and total assets (non-GAAP)
