Deposit growth and improved efficiency drive third quarter results

EUGENE, Ore., October 22, 2014 – Pacific Continental Corporation (Nasdaq: PCBK), the holding company of Pacific Continental Bank, today reported financial results for the third quarter 2014.

Recent highlights:

Net income

Net income for third quarter 2014 was $4.4 million or $0.25 per diluted share compared to net income of $3.9 million or $0.22 per diluted share in third quarter 2013. Third quarter 2014 financial results included the recovery of $300 thousand of legal fees expensed in prior reporting periods that improved earnings per diluted share by $0.01. Return on average assets, average book equity, and average tangible equity were 1.18%, 9.69%, and 11.13%, respectively, in third quarter 2014, compared to 1.09%, 8.77%, and 10.12% in third quarter 2013. The Company’s efficiency ratio was 57.04% for the third quarter 2014, compared to 62.81% in third quarter 2013.

“Our current quarter results reflect the success we have had in executing our business strategies,” said Hal Brown, chief executive officer. “We continue to be pleased with our efforts to improve our processes and efficiency, which we believe will result in long-term shareholder returns.”

Capital levels

The Company’s capital ratios continued to be well above the minimum for the FDIC’s minimum “well-capitalized” designation. At September 30, 2014, the Company’s Tier 1 leverage ratio, Tier 1 risk-based capital ratio, and Total risk-based capital ratios were 11.20%, 14.44% and 15.69%, respectively, as compared to 11.26%, 14.48% and 15.73% at June 30, 2014. 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 shares with purchases to take place over the next 12 months. During the third quarter 2014, the Company repurchased 132,358 shares at a weighted average price of $13.60 per share. Since the inception of the share repurchase plan, the Company has repurchased 267,080 shares at a weighted average price of $13.48 per share. Share repurchases and cash dividend payments to shareholders combined to maintain capital levels for third quarter 2014 relatively unchanged from December 31, 2011 levels.

Core deposits

Period-end Company-defined core deposits at September 30, 2014, were $1.05 billion, up $20.7 million from June 30, 2014, and were consistent with typical third quarter seasonal patterns. Average core deposits, which removes daily volatility in balances, for the third quarter 2014 were $1.04 billion compared to $1.01 billion and $972.4 million for second quarter 2014 and third quarter 2013, respectively. At period-end September 30, 2014, noninterest-bearing demand deposits totaled $390.8 million and represented 37.32% of core deposits.

“The success of our well-established business model in attracting core deposits and our focus on building long-term client relationships resulted in acceleration of our core deposit growth,” said Roger Busse, president and chief operating officer. “We continue to provide high levels of personal and technological service to our clients, which build a strong and stable core deposit base to support our lending activities.”

Loans

Outstanding gross loans at September 30, 2014, were $1.04 billion, up $4.7 million from June 30, 2014 and up $57.2 million over September 30, 2013. Loan growth for the first nine months of 2014 represented an annualized growth rate of 5.52%. This growth rate excludes unfunded construction and related lending commitments made during the last two quarters that total $31.5 million. Overall, loan growth during 2014 was primarily attributable to local real estate lending. Loan growth slowed in the current quarter due to pay offs on completed construction loans, early pay offs, and amortization of the portfolio. Loans to dental professionals expanded during the current quarter. At September 30, 2014, loans to dental practitioners totaled $307.1 million and represented 29.65% of the loan portfolio compared to 29.37% and 31.05% of the loan portfolio at June 30, 2014 and September 30, 2013, respectively. National dental loans at September 30, 2014, were $142.8 million, up $9.1 million over June 30, 2014.

Credit quality and statistics

For the sixth 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 September 30, 2014, declined to 1.52% compared to 1.72% at September 30, 2013. The allowance for loan losses as a percentage of nonperforming loans net of guarantees remained very strong at 536.22%. During the third quarter 2014, the Company recorded net loan recoveries totaling $47 thousand. Through September 30, 2014, net loan charge offs were $195 thousand compared to net loan recoveries of $206 thousand for the same period in 2013.

At September 30, 2014, nonperforming assets, net of government guarantees, totaled $16.1 million, or 1.08% of total assets, unchanged from June 30, 2014, but a decrease from the September 30, 2013 ratio of 1.50%. Nonperforming assets at September 30, 2014 were comprised of $2.9 million of nonperforming loans, net of government guarantees, and $13.2 million in other real estate owned. During the third quarter 2014, the Company transferred a $1.2 million nonaccrual commercial real estate loan into other real estate owned that resulted in no additional charge-off. Classified assets at September 30, 2014, totaled $43.5 million, a decrease of $600 thousand from the end of the prior quarter and a decline of $11 million from September 30, 2013. Loans past-due 30-89 days were 0.16% of total loans at September 30, 2014, compared to 0.08% of total loans at June 30, 2014.

“We are pleased with the continued incremental improvement of the overall credit quality of our loan portfolio,” said Casey Hogan, executive vice president and chief credit officer. “We are particularly pleased with the collection efforts of our Special Asset Group that resulted in a large recovery of legal expenses during the quarter.”

Net interest margin

The third quarter 2014 net interest margin averaged 4.28%, a decline of 6 basis points and 29 basis points from second quarter 2014 and third 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 30 basis points was due to nonrecurring interest income recoveries of $982 thousand recorded in third quarter 2013, which resulted in an increase of 30 basis points in the reported margin in that period. During the third quarter 2014, the accretion of loan fair value marks was $95 thousand and positively impacted the net interest margin by 3 basis points.

Noninterest income and expense

Third quarter 2014 noninterest income was $1.2 million, up $41 thousand from second quarter 2014, and down $250 thousand from third quarter 2013. Third quarter 2014 noninterest income also reflected lower merchant processing revenues resulting from the outsourcing of this activity that occurred during the fourth quarter 2013. The outsourcing of merchant processing also eliminated related processing expense.

Noninterest expense in third quarter 2014 was down $120 thousand and $1.3 million from second quarter 2014 and third quarter 2013, respectively. The decrease in noninterest expense on a linked-quarter basis was primarily due to the recovery of legal fees totaling $300 thousand recorded in prior reporting periods. The decline in year-over-year noninterest expense was also due to lower legal fees and reductions in other real estate expense. Third quarter 2013 results included other real estate valuation write-downs totaling $728 thousand that accounted for most of the decline in this category. Year-to-date September 30, 2014, noninterest expense of $27.9 million was down $1.5 million from 2013, when merger-related expense of $1.2 million was excluded from 2013 results.

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 certain non-GAAP financial measures provide investors with information useful in understanding the Company’s financial performance; however, readers of this report 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)
