Penns Woods Bancorp, Inc. Reports Fourth Quarter 2012 Operating Earnings

Williamsport, PA — January 23, 2013 - Penns Woods Bancorp, Inc. (NASDAQ:PWOD)

In 2012 Penns Woods Bancorp, Inc. continued their strong earnings and growth trend.  Record earnings of $13,850,000 were achieved for the twelve month period ending December 31, 2012.  The driving force behind the record net income was growth in loans and deposits with both reaching record levels.  The strong levels of earnings and balance sheet growth led to a stock price that reached an all time high (adjusted for stock splits/dividends) during the fourth quarter of 2012.

Highlights

·                  Net income from core operations (“operating earnings”), which is a non-GAAP measure of net income excluding net securities gains and bank owned life insurance gains on death benefit, decreased to $3,044,000 for the three months ended December 31, 2012 compared to $3,079,000 for the same period of 2011.  Net income from core operations increased to $12,893,000 for the twelve months ended December 31, 2012 compared to $11,952,000 for the same period of 2011.

·                  Operating earnings per share for the three months ended December 31, 2012 were $0.79 basic and dilutive compared to $0.80 basic and dilutive for the same period of 2011.  Operating earnings per share for the twelve months ended December 31, 2012 were $3.36 basic and dilutive compared to $3.12 basic and dilutive for the same period of 2011, an increase of 7.7%.

“Our strategy of acquiring high quality earning assets, while using core deposits to fund their acquisition, is paying rewards as reflected in the strong financial metrics for the three and twelve month periods ended.  Growth in the loan portfolio, in particular home equity products, and in the core deposit portfolio, led by NOW and money market accounts, are two of the primary drivers of this strategy.  Combine this strategy with the knowledge and hard work of our employees and you have the recipe to our success,” said Richard A. Grafmyre, CFP®, President and CEO.

A reconciliation of the non-GAAP financial measures of operating earnings, operating return on assets, operating return on equity, and operating earnings per share, described in the highlights, to the comparable GAAP financial measures is included at the end of this press release.

Net Income

Net income, as reported under GAAP, for the three and twelve months ended December 31, 2012 was $3,096,000 and $13,850,000 compared to $3,395,000 and $12,362,000 for the same periods of 2011.  Results for the three and twelve months ended December 31, 2012 compared to 2011 were impacted by a decrease in after-tax securities gains of $264,000 (from a gain of $316,000 to a gain of $52,000) for the three month periods and an increase in after-tax securities gains of $438,000 (from a gain of $410,000 to a gain of $848,000) for the twelve month periods.  In addition, a gain of $109,000 on death benefit related to bank owned life insurance was recorded during the first quarter of 2012.  Impacting the results for the three and twelve months ended December 31, 2012 was the recognition of $251,000 in expenses related to the announced acquisition of Luzerne National Bank Corporation.  Basic and dilutive earnings per share for the three and twelve months ended December 31, 2012 were $0.81 and $3.61 compared to $0.88 and $3.22 for the corresponding periods of 2011.  Return on average assets and return on average equity were 1.46% and 12.92% for the three months ended December 31, 2012 compared to 1.80% and 17.00% for the corresponding period of 2011.  Earnings for the twelve months ended December 31, 2012 correlate to a return on average assets and a return on average equity of 1.70% and 15.36% compared to 1.69% and 16.60% for the corresponding period of 2011.

Net Interest Margin

The net interest margin for the three and twelve months ended December 31, 2012 was 4.29% and 4.45% compared to 4.78% and 4.70% for the corresponding periods of 2011.  While the net interest margin has decreased year over year, net interest income on a fully taxable equivalent basis has increased $2,257,000 to $34,099,000 for the twelve months ended December 31, 2012 compared to the corresponding period of 2011.  Driving this increase is the growth in the loan portfolio of 17.5% coupled with the continued emphasis on core deposit growth.  The loan growth was driven by several campaigns related to increasing our market share in home equity products.  The primary funding for the loan growth was an increase in core deposits of 15.5%.  These deposits represent a lower cost funding source than time deposits and comprise 73.62% of total deposits at December 31, 2012 compared to 70.34% at December 31, 2011.  The average rate paid on total interest-bearing deposits decreased 23 and 28 basis points (bp) for the three and twelve months ended December 31, 2012 compared to the same periods of 2011.  The decrease in the rate paid on total interest-bearing deposits was led by a decrease in the rate paid on time deposits and money markets.  The rate paid on time deposits decreased 28 and 33 bp for the three and twelve months ended December 31, 2012 compared to the same periods of 2011 and the rate paid on money markets decreased 32 and 37 bp for the three and twelve months ended December 31, 2012 compared to the same periods of 2011.  The duration of the time deposit portfolio, which was shortened over the past several years, continues to be slowly lengthened due to the apparent bottoming or near bottoming of deposit rates.  FHLB long-term borrowings have been increased by $15,000,000 since December 31, 2011 to fund a combination of loan growth and FHLB debt that matured.  Long-term borrowings of $15,000,000 matured during the three months ended December 31, 2012 carrying an average rate of 4.18%, while $15,000,000 was obtained during the third quarter 2012 carrying an average rate of 0.90% and $15,000,000 was obtained during the fourth quarter 2012 carrying an average rate of 0.87%.

“The net interest margin has and will continue to encounter challenges as we move forward in the current low rate environment. We continue to add quality earning assets, but the earning assets being added are at a lower rate than the legacy earning assets that are maturing or are repricing lower at their rate reset dates.  In addition, our investment portfolio strategy continues to focus on shortening the portfolio so that we will have an increased level of cash flow when interest rates begin to increase.  This strategy does limit current earnings, but serves a key role in our long-term asset liability management strategy, while reducing risk in an upward rate environment in terms of interest rate and market value depreciation.  On the funding side of the balance sheet there is limited ability to reduce costs as deposit rates have previously been reduced with limited room for reductions remaining as market rates have stabilized at their current levels.  During the second half of 2012, borrowings from the FHLB totaling $30 million at a blended rate of less than one percent were obtained.  These

borrowings replaced $15 million in higher cost FHLB borrowings that were maturing and provided additional funding for the growth in the loan and investment portfolios,” commented President Grafmyre.

Assets

Total assets increased $92,582,000 to $856,535,000 at December 31, 2012 compared to December 31, 2011.  Net loans increased 17.7% to $504,615,000 at December 31, 2012 compared to December 31, 2011 due in large part to campaigns related to increasing home equity product market share.  Housing, transportation, and all other facets related to the Marcellus Shale natural gas exploration are creating loan opportunities and we are aggressively attempting to attract those loans that meet or exceed our credit standards.  The investment portfolio increased $19,165,000 from December 31, 2011 to December 31, 2012 due to a combination of market value increases and the purchase of short maturity bonds that have been utilized to reduce the portfolio duration and to provide current cash flow.

Non-performing Loans

Our non-performing loans to total loans ratio has decreased to 2.29% at December 31, 2012 from 2.75% at December 31, 2011.  The decrease in non-performing loans is primarily the result of a decrease in commercial loan delinquencies due to several partial charge-offs and the receipt of collateral in lieu of payment with the collateral now carried as other real estate owned.  The majority of non-performing loans are centered on several loans that are either in a secured position and have sureties with a strong underlying financial position or have a specific allocation for any impairment recorded within the allowance for loan losses.  Net loan charge-offs of $2,062,000 for the twelve months ended December 31, 2012 represented 0.44% of average loans for the twelve months ended December 31, 2012.  The allowance for loan losses decreased to 1.49% of total loans at December 31, 2012 from 1.64% at December 31, 2011 due to several large charge-offs and the increase in the loan portfolio.

Deposits

Deposits have grown 10.4%, or $60,362,000, to $642,026,000 at December 31, 2012 compared to December 31, 2011, with core deposits (total deposits excluding time deposits) increasing $63,532,000, while higher cost time deposits decreased $3,170,000.  Noninterest-bearing deposits have increased 3.2% to $114,953,000 at December 31, 2012 compared to December 31, 2011.  Also playing a significant role in increasing core deposits were NOW and money market accounts with growth rates of 28.1% and 16.4%, respectively.  Driving this growth is our commitment to easy-to-use products, community involvement, and emphasis on customer service.  We have also successfully implemented a targeted marketing campaign aimed at further strengthening our customer relationships, while also expanding our market penetration.  In addition our newest branch, Danville, opened in January 2012 and has gathered approximately $27 million in deposits during the first twelve months of its operation.

Shareholders’ Equity

Shareholders’ equity increased $13,266,000 to $93,726,000 at December 31, 2012 compared to December 31, 2011.  The accumulated other comprehensive gain of $5,357,000 at December 31, 2012 is a result of an increase in unrealized gains on available for sale securities from an unrealized gain of $2,914,000 at December 31, 2011 to an unrealized gain of $10,164,000 at December 31, 2012.  However, the amount of accumulated other comprehensive gain at December 31, 2012 was also impacted by the change in net excess of the projected benefit obligation over the market value of the plan assets of the defined benefit pension plan resulting in an increase in the net loss of $674,000 to $4,807,000 at December 31, 2012.  The current level of shareholders’ equity equates to a book value per share of $24.42 at December 31, 2012 compared to $20.97 at December 31, 2011 and an equity to asset ratio of 10.94% at December 31, 2012 compared to 10.53% at December 31, 2011.  Excluding accumulated other comprehensive gain/loss, book value per share was $23.02 at December 31, 2012 compared to $21.29 at December 31, 2011.  Dividends per share paid to shareholders were $0.47 and $1.88 for

the three and twelve months ended December 31, 2012 compared to $0.46 and $1.84 for the three and twelve months ended December 31, 2011.

NOTE:  This press release contains financial information determined by methods other than in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”).  Management uses the non-GAAP measure of net income from core operations in its analysis of the company’s performance. This measure, as used by the Company, adjusts net income determined in accordance with GAAP to exclude the effects of special items, including significant gains or losses that are unusual in nature such as net securities gains and losses. Because certain of these items and their impact on the Company’s performance are difficult to predict, management believes presentation of financial measures excluding the impact of such items provides useful supplemental information in evaluating the operating results of the Company’s core businesses. These disclosures should not be viewed as a substitute for net income determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies.
