Clifton Bancorp Inc. Announces

Financial Results for the First Quarter Ended June 30, 2017;

Declares Cash Dividend

Clifton, New Jersey – July 26, 2017 — Clifton Bancorp Inc. (Nasdaq: CSBK) (the “Company”), the holding company for Clifton Savings Bank (“CSBK”), today announced results for the first quarter ended June 30, 2017. Net income for the first quarter was $1.40 million ($0.07 per share, basic and diluted) as compared to net income of $1.02 million ($0.04 per share, basic and diluted) for the first quarter ended June 30, 2016.

The Board of Directors also announced today a cash dividend of $0.06 per common share for the quarter ended June 30, 2017. The dividend will be paid on or about August 25, 2017 to stockholders of record on August 11, 2017.

Notable Items

Paul M. Aguggia, Chairman and Chief Executive Officer, stated, “We created momentum in the first quarter of our new fiscal year and we look forward to building on several positive trends. Our net income grew 38% over our first quarter one year ago. Our strategic focus on organic growth led to meaningful deposit and loan increases year over year and in the first quarter. We returned capital to our shareholders through the continuation of our repurchase program and regular dividend, as well as a special dividend paid in July 2017 and recorded in the first quarter. In short, we are competing effectively in desirable and competitive markets that continue to challenge our margin but also give us real opportunities to grow prudently and profitably.”

Balance Sheet and Credit Quality Review

Total assets increased $93.2 million, or 6.5%, to $1.53 billion at June 30, 2017, from $1.43 billion at March 31, 2017. The increase in total assets was primarily due to an increase in cash and cash equivalents and loans.

Net loans increased $66.9 million, or 6.6%, to $1.07 billion at June 30, 2017, from $1.01 billion at March 31, 2017. One-to-four family real estate loans increased $13.9 million, or 2.0%, while multi-family and commercial real estate loans increased $52.5 million, or 17.8%, during the quarter ended June 30, 2017. Securities, including both available for sale and held to maturity issues, decreased $11.2 million, or 3.6%, to $304.1 million at June 30, 2017, from $315.3 million at March 31, 2017, mainly because of maturities and repayments. Cash and cash equivalents increased $33.6 million, or 229.5%, to $48.3 million at June 30, 2017, from $14.7 million at March 31, 2017, as a portion of cash flows from deposits and borrowed funds were not yet redeployed into higher yielding assets.

Deposits increased $47.6 million, or 5.6%, to $892.4 million at June 30, 2017 from $844.8 million at March 31, 2017. CSBK launched a new, high-yielding checking account in May 2017 that was responsible for a significant percentage of the quarter’s deposit growth. Borrowed funds increased $49.0 million, or 17.8%, to $324.8 million at June 30, 2017 from $275.8 million at March 31, 2017. The Company’s outstanding borrowings at June 30, 2017 had a weighted average rate of 1.77% and a weighted average term of 19 months. All outstanding borrowings are with the Federal Home Loan Bank of New York.

Total stockholders’ equity decreased $8.5 million, or 2.9%, to $288.1 million at June 30, 2017 from $296.6 million at March 31, 2017, primarily as a result of $4.0 million in repurchases of common stock, and the payment of $6.6 million in cash dividends, which included the impact of the July 2017 $0.25 special dividend totaling $5.3 million, partially offset by net income of $1.4 million.

Nonaccrual loans increased $223,000, or 6.0%, to $3.9 million at June 30, 2017 as compared to $3.7 million at March 31, 2017. Included in nonaccrual loans at June 30, 2017 were five loans totaling $1.0 million that were current or less than 90 days delinquent, but which were previously 90 days or more delinquent and on nonaccrual status pending a sustained period of repayment performance (generally six months). The percentage of nonperforming loans to total gross loans decreased to 0.40% at June 30, 2017 from 0.41% at March 31, 2017. The allowance for loan losses to nonperforming loans increased to 155.38% at June 30, 2017, from 146.11% at March 31, 2017 as nonperforming one-to-four family loans increased slightly and provisions were added (mainly due to significant increases in loans outstanding).

Income Statement Review

Net interest income increased by $947,000, or 13.6%, to $7.9 million for the quarter ended June 30, 2017, as compared to $6.9 million for the quarter ended June 30, 2016. Net interest income increased despite a decrease of 8 basis points in net interest margin and a decrease of $6.7 million in average net interest-earning assets, primarily due to other categories of interest-earning assets being redeployed into CSBK’s highest yielding asset category (multi-family and commercial loans).

The provision for loan losses increased $64,000, or 12.2%, to $590,000 for the quarter ended June 30, 2017, as compared to $526,000 for the quarter ended June 30, 2016. The increase was mainly due to the significant growth in the balance of outstanding loans, partially offset by slightly more favorable trends in qualitative factors considered in the periodic reviews of the general valuation allowance.

Non-interest income for the quarter ended June 30, 2017 decreased $80,000, or 15.2%, to $447,000, as compared to $527,000 for the quarter ended June 30, 2016, as the 2016 period included a $84,000 gain on the sale of securities. There were no sales of securities in the 2017 period.

Non-interest expenses for the quarter ended June 30, 2017 increased $133,000, or 2.4%, to $5.6 million, as compared to $5.5 million for the quarter ended June 30, 2016. The increase consisted primarily of increases in advertising and marketing expenses of $81,000, or 52.9%, and occupancy expenses of $43,000, or 10.3%, partially offset by a decrease in federal deposit insurance premium of $43,000, or 31.2%. The increase in advertising and marketing expenses was mainly related to the costs to promote CSBK’s recently opened Hoboken and Montclair banking centers, as well as the new checking account product referenced above. The increase in occupancy expenses was mainly related to operational costs of the Hoboken and Montclair banking centers. The decrease in federal deposit insurance premium in the 2017 period was due to the revision of the FDIC assessment system, which began on July 1, 2016, and is not reflected in the 2016 period expenses. Revisions for “small institutions” (under $10 billion in assets) resulted in, among other things, a change in the financial ratios method used to determine assessment rates.

Income taxes for the quarter ended June 30, 2017 increased $285,000, or 63.6%, to $733,000, as compared to $448,000 for the quarter ended June 30, 2016. The increase resulted from higher pre-tax income, coupled with an increase in the effective income tax rate. The overall effective income tax rate was 34.3% for the 2017 period compared with 30.6% for the 2016 period, as non-taxable interest from municipal securities and bank-owned life insurance represented a smaller portion of overall income.
