FOR IMMEDIATE RELEASE

BENEFICIAL BANCORP, INC. ANNOUNCES THIRD QUARTER RESULTS AND CASH DIVIDEND TO SHAREHOLDERS

PHILADELPHIA, PENNSYLVANIA, October 20, 2017 — Beneficial Bancorp, Inc. (“Beneficial”) (NASDAQ GS: BNCL), the parent company of Beneficial Bank (the “Bank”), today announced its financial results for the three and nine months ended September 30, 2017.  Beneficial recorded net income of $9.4 million and $27.3 million, or $0.13 and $0.37 per diluted share, for the three and nine months ended September 30, 2017, respectively, compared to net income of $10.1 million and $17.8 million, or $0.14 and $0.24 per diluted share, for the three and nine months ended September 30, 2016.  Net income for the three months ended September 30, 2016 included a $1.8 million investment gain from the sale of stock that we held in a financial institution that was acquired.  Net income for nine months ended September 30, 2016 included $8.8 million of merger and restructuring charges related to the acquisition of Conestoga Bank (“Conestoga”) and the Bank’s expense management reduction program.

On October 19, 2017, the Company declared a cash dividend of 6 cents per share, payable on or after November 9, 2017, to common shareholders of record at the close of business on October 30, 2017.

Highlights for the three and nine months ended September 30, 2017, are as follows:

·                                          Net interest margin totaled 3.09% and 3.06% for the three and nine months ended September 30, 2017 compared to 3.08% and 3.00% for the same periods in 2016, respectively.  Net interest margin year over year has benefited from organic loan growth, the impact of the Conestoga acquisition, and continued improvement in the mix of our balance sheet.

·                                          Net interest income increased $2.4 million and $13.9 million, or 5.9% and 12.5%, respectively, for the three and nine months ended September 30, 2017, compared to the same periods in the prior year primarily due to the Conestoga acquisition and organic growth in our loan portfolio.

·                                          During the nine months ended September 30, 2017, our loan portfolio increased $22.0 million, representing 0.73% annualized loan growth.  Annualized growth of 4.0% in our commercial loan portfolio was offset by decreases in our consumer loans primarily as a result of the run-off of our discontinued indirect auto lending portfolio.

·                                          During the three and nine months ended September 30, 2017, the Company recorded a $352 thousand and a $1.4 million net gain on the sale of $3.6 million and $14.8 million of the guaranteed portion of SBA loans, respectively.

·                                          Charge-offs continue to remain low.  Net charge-offs for the nine months ended September 30, 2017, totaled $2.1 million, or 7 basis points annualized of average loans, compared to net charge-offs of $1.0 million, or 4 basis points annualized of average loans, in the same period in the 2016.

·                                          Asset quality metrics continued to remain strong with a non-performing assets to total assets, excluding government guaranteed student loans, of 0.36% at September 30, 2017.  Our allowance for loan losses totaled $43.3 million, or 1.07% of total loans, as of September 30, 2017, compared to $43.3 million, or 1.08% of total loans, as of December 31, 2016.

·                                          During the nine months ended September 30, 2017, the Company purchased 703,800 shares under its previously announced stock repurchase plan.  Our tangible capital to tangible assets decreased to 15.34% at September 30, 2017, compared to 15.70% at September 30, 2016.  The decrease in this ratio can be

attributed to share repurchases and cash dividends.  Tangible book value per share totaled $11.44 at September 30, 2017.

Gerard Cuddy, Beneficial’s President and CEO, stated “Our financial results continue to improve, driven by growth in our balance sheet, continued favorable asset quality and management of our expense base.  Although we are seeing some growth in our commercial lending businesses, the pace of growth has slowed.  Our focus remains on employee engagement, a superior customer experience, prudent capital management and organic growth to continue to improve the financial performance of our organization.”

Balance Sheet

Total assets increased $79.0 million, or 1.4%, to $5.82 billion at September 30, 2017, compared to $5.74 billion at December 31, 2016.  The increase in total assets was primarily due to an increase in cash and cash equivalents and loan growth, partially offset by a decline in investment securities.

Cash and cash equivalents increased $190.0 million to $477.0 million at September 30, 2017, from $287.0 million at December 31, 2016.  The increase in cash and cash equivalents was primarily driven by investment maturities and repayments and an increase in borrowed funds to meet projected future liquidity needs and secure lower funding rates.

Investments decreased $124.2 million, or 11.6%, to $951.1 million at September 30, 2017, compared to $1.08 billion at December 31, 2016, as we continued to focus on improving our balance sheet mix by reducing the percentage of our assets in investments and growing our loan portfolio.  We continue to focus on maintaining a high quality investment portfolio that provides a steady stream of cash flows both in the current and in rising interest rate environments.

Loans increased $22.0 million, or 0.73% annualized growth, to $4.03 billion at September 30, 2017, from $4.01 billion at December 31, 2016.  The increase in loans was primarily due to organic growth in our commercial real estate and residential real estate loan portfolios offset by an $89.4 million decrease in our consumer loan portfolio due primarily to a decrease in indirect auto loans resulting from our run-off of this portfolio segment.  As previously disclosed, we decided to exit the indirect lending business in the first quarter of 2017.

Deposits increased $12.7 million, or 0.41% annualized growth, to $4.17 billion at September 30, 2017, from $4.16 billion at December 31, 2016.  Deposit growth was primarily achieved through organic core deposit growth of $33.0 million in savings accounts, partially offset by a decrease in interest bearing business checking accounts.

Borrowings increased $50.0 million to $540.4 million at September 30, 2017, and are being used as a low cost funding source to replace higher cost brokered CDs.

Stockholders’ equity increased $24.6 million, or 2.4%, to $1.04 billion at September 30, 2017, from $1.01 billion at December 31, 2016.  The increase in stockholders’ equity was primarily due to net income of $27.3 million as well as the issuance of 1,015,943 shares from the exercise of stock options resulting in an increase in additional paid in capital, partially offset by the declaration of cash dividends and stock repurchases during the first nine months of 2017.

Net Interest Income

For the three months ended September 30, 2017, net interest income was $42.4 million, an increase of $2.4 million, or 5.9%, from the three months ended September 30, 2016. The increase in net interest income was primarily due to an increase in average interest earning assets of $284.7 million with growth occurring in our higher yielding loan portfolio.  The net interest margin totaled 3.09% for the three months ended September 30, 2017 as compared to 3.08% for the same period in 2016. During the three months ended September 30, 2017, the net interest margin was negatively impacted 11 basis points by higher cash levels due to slower than anticipated loan growth as average cash for the quarter totaled $388.0 million, an increase of $257.1 million from $130.9 million during the three months ended September 30, 2016.

For the nine months ended September 30, 2017, Beneficial reported net interest income of $124.9 million, an increase of $13.9 million, or 12.5%, from the nine months ended September 30, 2016. The increase in net interest income was primarily due to the acquisition of Conestoga during the second quarter of 2016 and strong organic loan growth, which

2

resulted in higher interest earning assets of $501.3 million in 2017 compared to 2016.  Our net interest margin increased to 3.06% for the nine months ended September 30, 2017, from 3.00% for the same period in 2016.

Non-interest Income

For the three months ended September 30, 2017, non-interest income totaled $7.1 million, a decrease of $1.1 million, or 13.8%, from the three months ended September 30, 2016.  The decrease was primarily due to a $1.8 million investment gain recorded during the third quarter of 2016 from the sale of stock that we held in a financial institution that was acquired, and a $493 thousand swap fee earned on a commercial real estate loan recorded during the third quarter of 2016.  These decreases to non-interest income were partially offset by a $352 thousand net gain on the sale of $3.6 million of SBA loans recorded during the third quarter of 2017, a $518 thousand increase in limited partnership earnings, and a $178 thousand increase in interchange fee income.

For the nine months ended September 30, 2017, non-interest income totaled $21.6 million, an increase of $2.0 million, or 10.2%, from the nine months ended September 30, 2016.  The increase was primarily due to a $1.4 million net gain on the sale of $14.8 million of SBA loans recorded during the nine months ended September 30, 2017, a $921 thousand increase in limited partnership earnings, a $627 thousand increase in interchange fee income, a $394 thousand increase in income from other life insurance, and a $322 thousand increase in insurance and advisory commission and fee income.  These increases to non-interest income were partially offset by a $1.8 million investment gain recorded during the third quarter of 2016 from the sale of stock that we held in a financial institution that was acquired, and a $493 thousand swap fee earned on a commercial real estate loan recorded during the third quarter of 2016.

Non-interest Expense

For the three months ended September 30, 2017, non-interest expense totaled $33.8 million, an increase of $576 thousand, or 1.7%, from the three months ended September 30, 2016.  The increase in non-interest expense was primarily due to an increase in salaries and employee benefits of $641 thousand due primarily due to increased costs associated with equity awards granted under the 2016 Omnibus Incentive Plan as well as annual merit increases.

For the nine months ended September 30, 2017, non-interest expense totaled $103.4 million, a decrease of $230 thousand, or 0.2%, from the nine months ended September 30, 2016. The decrease in non-interest expense was primarily due to $8.8 million of merger and restructuring charges related to the acquisition of Conestoga and our April 2016 expense management reduction program recorded during the nine months ended September 30, 2016.  This decrease to non-interest expense was partially offset by an increase in salaries and employee benefits of $5.6 million and a $1.6 million increase in board fees due primarily to increased costs associated with equity awards granted under the 2016 Omnibus Incentive Plan as well as annual merit increases. The decrease in non-interest expense during the nine months ended September 30, 2017 was also offset by a $513 thousand increase in occupancy expense related to the acquisition of Conestoga Bank.

Income Taxes

For the three months ended September 30, 2017, we recorded a provision for income taxes of $5.5 million, reflecting an effective tax rate of 36.8%, compared to a provision for income taxes of $4.9 million, reflecting an effective tax rate of 32.8% for the three months ended September 30, 2016.  The increase in the effective tax rate for the three months ended September 30, 2017 compared to the same period a year ago is primarily due to non-deductible compensation and lower tax-exempt interest income.

For the nine months ended September 30, 2017, we recorded a provision for income taxes of $13.7 million, reflecting an effective tax rate of 33.5%, compared to a provision for income taxes of $9.1 million, reflecting an effective tax rate of 33.9%, for the nine months ended September 30, 2016.  The net reduction in the effective tax rate for the nine months ended September 30, 2017 compared to the same period a year ago was primarily lowered by the impact of excess tax benefits recorded to income tax expense in 2017 associated with stock based compensation, partially offset by non-deductible compensation and lower tax-exempt interest income.  Management believes the effective tax rate for the remainder of 2017 will likely remain closer to the 35.0% statutory tax rate.

Asset Quality

Non-accruing loans, excluding government guaranteed student loans, increased $8.7 million to $20.8 million at September 30, 2017, compared to $12.1 million at December 31, 2016.  Our ratio of non-performing assets to total assets, excluding government guaranteed student loans, increased to 0.36% at September 30, 2017, compared to 0.22% at December 31, 2016.  The increase in non-accruing loans can primarily be attributed to the downgrade to doubtful and change to non-accrual of a shared national credit during the first quarter of 2017 with an outstanding balance of $8.7 million as of September 30, 2017.  The Company has reviewed the status of this shared national credit and determined that no charge-off or specific reserves were required as of September 30, 2017.

As a result of loan growth and charge-offs, we recorded a $750 thousand and $2.1 million provision for loan losses during the three and nine months ended September 30, 2017, respectively.

Our allowance for loan losses totaled $43.3 million, or 1.07% of total loans, as of September 30, 2017, compared to $43.4 million, or 1.06% of total loans, as of June 30, 2017, and $43.3 million, or 1.08% of total loans, as of December 31, 2016.
