As previously announced, on March 29, 2017, Mid Penn and the Bank entered into a merger agreement with The Scottdale Bank & Trust Company (“Scottdale”) under which Scottdale will merge with and into Mid Penn Bank, with Mid Penn Bank remaining as the surviving entity.  The parties have been working closely together to obtain the required regulatory and shareholder approvals to move forward with the transaction and integration activities contemplated by the merger agreement.  Both banks are holding special shareholder meetings on November 17, 2017, to vote to adopt the merger agreement.  The meeting of Mid Penn shareholders will be held beginning at 9:00 a.m., local time, at the Halifax Area Ambulance and Rescue Association, Inc., 31 Bunker Hill Road, Halifax, Pennsylvania.  The meeting of Scottdale shareholders will be held at 2:00 p.m., local time, at the Pleasant Valley Country Club, 440 Pleasant Valley Road, Connellsville, Pennsylvania.

PRESIDENT’S STATEMENT

I am pleased to report Mid Penn's financial results for the three and nine months ended September 30, 2017, which reflect double-digit percentage increases in earnings for both the quarter and year-to-date as compared to the same periods in 2016.  Our earnings for the nine months ended September 30, 2017, when excluding the after-tax impact of merger-related expenses increased 23 percent compared to earnings for the nine months ended September 30, 2016.  Our earnings for the third quarter of 2017, when excluding the after-tax impact of merger-related expenses, reflect an over 30 percent increase compared to the third quarter of 2016.  Our ability to continue to produce and report these phenomenal results represent the commitment of our entire Mid Penn team to grow high quality loans funded by low cost deposits, to grow fee-based revenues, to improve asset quality, and to control operating expenses while investing in important technologies to enhance the customer experience and efficient operation of our Bank.

Given these favorable quarterly results, on October 25, 2017 the Board of Directors declared a cash dividend of $0.13 per common share of Mid Penn stock, payable November 27, 2017 to shareholders of record as of November 8, 2017.

We are grateful to be a part of the communities we serve, and look forward to building new and existing relationships with our commercial, retail, and wealth management customers, both organically and through the expansion of our operating footprint.  We look forward to our special meeting of shareholders on November 17th, as we are confident that our shareholders and those of Scottdale will affirm the decision of our Boards to approve the merger in the best interests of both organizations.  We also are finishing the construction of our newest branch in Halifax, PA, which we expect to begin serving customers in the first quarter of 2018.  

These are exciting times for Mid Penn, both given the continued favorable core performance reflected in our results through September 30, 2017, and as we look towards the opportunities awaiting us for the remainder of 2017 and into the new year and beyond.

OPERATING RESULTS

Net Interest Income and Net Interest Margin

Net interest income was $9,516,000 for the three months ended September 30, 2017, an increase of $758,000 or 9 percent compared to net interest income of $8,758,000 for the three months ended September 30, 2016.  Through the first nine months of 2017, net interest income was $28,101,000, an increase of $2,385,000 or 9 percent compared to net interest income of $25,716,000 for the same period in 2016.

For the three months ended September 30, 2017, Mid Penn’s tax-equivalent net interest margin was 3.64% compared to 3.71% for the three months ended September 30, 2016.  For the nine months ended September 30, 2017, Mid Penn’s tax-equivalent net interest margin was 3.73% versus 3.83% for the nine months ended September 30, 2016.  The decrease in the net interest margin year over year was primarily attributed to the lower yield earned on the investment portfolio.  For the first nine months of 2017, the overall investment portfolio yield was 2.35%, compared to an investment portfolio yield of 2.93% for the same period in 2016.  The reduction was attributed to Mid Penn establishing an $82,625,000 held-to-maturity investment portfolio including lower-risk and lower-yielding U.S. Treasury notes and U.S. agency mortgage-backed securities in the first quarter of 2017.  The held-to-maturity portfolio was established to support the Bank’s growth in public fund deposit pledging requirements.  

Noninterest Income

During the three months ended September 30, 2017, noninterest income was $1,564,000 reflecting an increase of $145,000 or 10 percent compared to noninterest income of $1,419,000 for the three months ended September 30, 2016.  For the nine months ended September 30, 2017, noninterest income totaled $4,362,000, an increase of $313,000 or 8 percent, compared to noninterest income of $4,049,000 for the same period in 2016.

Mid Penn increased its origination and sales activities related to Small Business Administration (“SBA”) loans, resulting in gains of $703,000 from related loan sales during the first nine months of 2017, an increase of $349,000 or 99 percent compared to SBA loan sales gains of $354,000 for the first nine months of 2016.  More qualified small business borrowers continue to take advantage of Mid Penn’s Preferred Lender status with the SBA.

Income from fiduciary activities was $613,000 for the first nine months of 2017, an increase of $264,000 or 76 percent compared to fiduciary income of $349,000 during the same period in 2016.  These additional revenues were attributed to trust assets under management significantly increasing over the past twelve months as a result successful business development efforts by Mid Penn’s expanded team of trust and retail investment officers.  

For the nine months ended September 30, 2017, service charges on deposits were $554,000, an increase of $70,000 or 14 percent, compared to service charges of $484,000 for the nine months ended September 30, 2016.  This upturn was driven by an increase in the volume of transactional deposit accounts, and by an increase in charges collected including overdraft fees.

ATM debit card interchange income was $689,000 for the nine months ended September 30, 2017, an increase of $66,000 or 11 percent compared to interchange income of $623,000 for the same period in 2016.  The additional income is a result of an increased volume of transactional checking accounts and an increase in Mid Penn Bank ATM debit card transactions across our market area.

Net gains on sales of securities were $42,000 for the first nine months of 2017, a decrease of $371,000 or 90 percent compared to net gains on sales of securities of $413,000 during the same period ended September 30, 2016.  During the first nine months of 2016, Mid Penn took advantage of favorable fixed income investment market conditions and increased fair values on several securities to reposition some of its investment portfolio, including selling a large volume of longer-term and rate-sensitive CMOs, as well as certain municipal bonds and agency notes.

Noninterest Expense

During the three months ended September 30, 2017, noninterest expenses totaled $7,960,000, an increase of $795,000 or 11 percent compared to noninterest expenses of $7,165,000 for the three months ended September 30, 2016.  For the nine months ended September 30, 2017, noninterest expenses totaled $23,320,000, an increase of $2,242,000 or 11 percent compared to noninterest expenses of $21,078,000 for the first nine months in 2016.

Salaries and employee benefits expense increased $1,238,000 or 11 percent during the first nine months of 2017 versus the same period in 2016, with the increase attributable to (i) the addition of lending personnel, credit support staff, and executive management in alignment with Mid Penn’s core banking growth, (ii) added retail staff for three new branch offices at Oregon Pike, New Holland, and Orwigsburg, all of which opened after September 30, 2016, and (iii) increased healthcare costs from Mid Penn’s self-funded medical plan during the first nine months of 2017.

Occupancy expenses for the nine months ended September 30, 2017 increased $330,000 or 21 percent compared to the same period in 2016.  In the twelve months since September 30, 2016, Mid Penn added facility operating costs associated with opening the above-noted three new branch offices, as well as loan production offices in Lancaster and Franklin Counties in Pennsylvania.

Mid Penn’s FDIC assessment increased by $151,000 or 35 percent from $434,000 during the nine months ended September 30, 2016, to $585,000 during the nine months ended September 30, 2017, due to the Company’s growing deposits and assets, which increased the base amount used to determine the FDIC insurance assessment.

Legal and professional fees for the nine months ended September 30, 2017 increased by $69,000 or 13 percent compared to the same period in 2016 due to increased legal and professional fees for wealth management, audit, and public relations activities.

Software licensing fees increased by $81,000 or 8 percent from $1,015,000 during the nine months ended September 30, 2016, to $1,096,000 during the nine months ended September 30, 2017.  The increase is a result of additional costs to upgrade internal systems to better serve our customers, as well as increases in per-transaction and per-account data processing fees as our customer base and transaction volume grow.

Pennsylvania bank shares tax expense decreased $106,000 or 17 percent during the nine months ended September 30, 2017 versus the same period in 2016, due to the additional Pennsylvania-eligible tax credits generated from Mid Penn’s donations to support education and economic development throughout the markets it serves.

FINANCIAL CONDITION

Loans

Total loans at September 30, 2017 were $877,386,000 compared to $813,924,000 at December 31, 2016, an increase of $63,462,000 or 8 percent (or 10 percent on an annualized basis).  The main driver of Mid Penn’s loan growth continues to be commercial loans, including both commercial and industrial financing, and commercial real estate credits.

Deposits

Total deposits increased $91,302,000 or over 9 percent (13 percent on an annualized basis), from $935,373,000 at December 31, 2016 to $1,026,675,000 at September 30, 2017, due to both retail branch deposit growth and cash management sales efforts.

Investments

Mid Penn added a held-to-maturity pool to its overall investment portfolio during the first nine months of 2017, and at September 30, 2017, had $82,625,000 of amortized cost invested in held-to-maturity securities.  No securities were designated as held-to-maturity at December 31, 2016.  Mid Penn’s total available-for-sale securities portfolio decreased $37,112,000 or 28 percent, from $133,625,000 at December 31, 2016 to $96,513,000 at September 30, 2017, as some available-for-sale investments were sold to fund both the held-to-maturity pool and loan growth.

Capital

Shareholders’ equity increased by $6,924,000 or 10 percent, from $70,467,000 at December 31, 2016 to $77,391,000 at September 30, 2017.  The increase during the first nine months of 2017 was attributed to both (i) growth in retained earnings through an increase in year-to-date net income and (ii) other comprehensive income primarily due to the after-tax unrealized appreciation in the value of the available-for-sale investment portfolio since December 31, 2016.  Regulatory capital ratios for both Mid Penn and the Bank exceeded regulatory “well-capitalized” levels at both September 30, 2017 and December 31, 2016.

ASSET QUALITY

Total nonperforming assets were $8,523,000 at September 30, 2017, compared to $5,759,000 at December 31, 2016 and $6,026,000 at September 30, 2016.  The ratio of nonperforming assets to total loans and other real estate was 0.97% as of September 30, 2017, compared to 0.71% as of December 31, 2016, and 0.76% as of September 30, 2016.  The increase in nonperforming assets is primarily due to one larger loan relationship totaling $4.5 million, with a $150,000 specific allowance allocation, being placed on nonaccrual status during the third quarter of 2017.  Mid Penn had net loan recoveries of $94,000 for the nine months ended September 30, 2017, compared to net loan charge-offs of $6,000 during the same period of 2016.  During the first nine months of 2017, Mid Penn successfully recovered principal from continued collection and workout efforts on previously impaired loan relationships, including a $318,000 recovery from a loan that was partially charged-off in 2010.

Management performs a monthly evaluation of the adequacy of the loan and lease loss allowance and based on this evaluation, no loan loss provision was recorded for the three months ended September 30, 2017, compared to a loan loss provision of $585,000 for the three months ended September 30, 2016.  For the nine months ended September 30, 2017, the recorded loan loss provision was $225,000 compared to a loan loss provision of $1,320,000 for the nine months ended September 30, 2016.  The significant net principal recoveries during the nine months ended September 30, 2017 added $94,000 to the allowance for loan loss balance.  Additionally, during the nine months ended September 30, 2017, Mid Penn had favorable workouts of certain impaired credits which reduced the amount of required specific allocations in the allowance.  The allowance for loan and lease losses as a percentage of total loans was 0.86% at September 30, 2017, compared to 0.88% at December 31, 2016, and 0.95% at September 30, 2016.  Loan loss reserves as a percentage of nonperforming loans were 88% at September 30, 2017, compared to 130% at December 31, 2016, and 135% at September 30, 2016.  Management believes, based on information currently available, that the allowance for loan and lease losses of $7,502,000 is adequate as of September 30, 2017 to cover specifically identifiable loan losses as well as estimated losses inherent in the portfolio.

RECONCILIATION OF NON-GAAP MEASURES (Unaudited:)

This press release contains financial information determined by methods other than in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"). For tangible book value, the most directly comparable financial measure calculated in accordance with GAAP is our book value.  We believe that this measure is important to many investors in the marketplace who are interested in changes from period to period in book value per common share exclusive of changes in intangible assets.  Goodwill and other intangible assets have the effect of increasing total book value while not increasing our tangible book value.  We believe that the adjusted efficiency ratio is useful to investors because, by removing the impact of foreclosed assets and non-recurring merger-related expenses, it allows investors to more easily compare our efficiency to other companies and banks in the industry.  We believe earnings per share excluding the after-tax impact of merger-related expenses provides important supplemental information in evaluating Mid Penn’s operating results because these charges are not incurred as a result of ongoing operations.  Income tax effects of non-GAAP adjustments are calculated using the applicable statutory tax rate for the jurisdictions in which the charges (benefits) are incurred, while taking into consideration any valuation allowances or non-deductible portions of the non-GAAP adjustments. This non-GAAP disclosure has limitations as an analytical tool, should not be viewed as a substitute for financial measures determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of Mid Penn’s results and financial condition as reported under GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies. Management believes that this non-GAAP supplemental information will be helpful in understanding Mid Penn’s ongoing operating results. This supplemental presentation should not be construed as an inference that Mid Penn’s future results will be unaffected by similar adjustments to be determined in accordance with GAAP.
