PCSB Financial Corporation Announces Fourth Quarter and Full Year Earnings

Yorktown Heights, New York; August 3, 2017 – PCSB Financial Corporation (the “Company”) (NASDAQ: PCSB), parent of PCSB Bank (the “Bank”), today announced a net loss of $1.8 million for the three months ended June 30, 2017 and net income of $3.2 million for the year ended June 30, 2017. This compares to a net loss of $156,000 for the three months ended June 30, 2016 and net income of $2.9 million for the year ended June 30, 2016.

The following nonrecurring items were recorded in the periods indicated:

• A $5.0 millionpre-tax expense recorded in the three months and year ended June 30, 2017 related to the Company’s contribution and establishment of the PCSB Community Foundation.

• A $919,000pre-tax curtailment of the Bank’s defined benefit plan resulting in a reduction to the salaries and benefits component of noninterest expense recorded in the year ended June 30, 2017.

• A $1.6 million settlement on an acquired loan included in other noninterest income in the year ended June 30, 2017.

• A $521,000 lease write-down expense in the year ended June 30, 2017.

• Merger-related expenses totaling $629,000 and $790,000 for the quarter and year ended June 30, 2016, respectively.

On a non-GAAP basis, which excludes the nonrecurring items discussed above, the Company recorded net income of $1.5 million for the three months ended June 30, 2017 and $5.2 million for the year ended June 30, 2017. This compares to non-GAAP net income of $473,000 for the three months ended June 30, 2016 and $3.7 million for the year ended June 30, 2016 (see page 7 for a reconciliation of GAAP to non-GAAP measures).

Effective April 20, 2017, PCSB Bank completed itsmutual-to-stock conversion and the Company completed its related initial public offering. Accordingly, 2016 financial results are for the Bank only.

President’s Comments

“The end of our fiscal year marks another step in the transformation of PCSB Bank,” said Joseph Roberto, Chairman, President and Chief Executive Officer of PCSB Financial Corporation. “Having raised over $163 million in capital during this past quarter will enable PCSB Bank to continue to be the premier community bank in the Hudson Valley Region.”

Mr. Roberto continued, “We enter our new fiscal year with the excitement of the stock’s strong performance following the IPO and we were pleased to be added to the Russell 2000 index this past quarter. We are also pleased that our fourth quarter reflects increased core earnings, as we move forward in deploying the new capital in a prudent way that will be beneficial to our shareholders. In addition, we continued our commitment to the communities we serve through the establishment and contribution to our foundation.”

Income Statement Summary

Net interest income increased $704,000 to $9.4 million and $1.4 million to $35.7 million for the three months and year ended June 30, 2017, respectively, compared to the same periods in 2016. Net interest income increased as a result of an increase in the average balances of loans and investment securities outstanding, partially offset by an increase in the average balance of deposits and the average rate paid on deposits. The net interest margin decreased from 2.91% for the three months ended June 30, 2016 to 2.81% for the three months ended June 30, 2017 and decreased from 2.92% for the year ended June 30, 2016 to 2.88% for the year ended June 30, 2017. The decreases in the net interest margin were primarily due to the conversion proceeds being initially invested in generally lower yielding securities.

The provision for loan losses decreased $1.4 million and $1.0 million for the three months and year ended June 30, 2017, respectively, compared to the same periods in 2016. Recoveries, net of charge-offs, were $321,000 and $285,000 for the three months and year ended June 30, 2017, respectively, compared to charge-offs, net of recoveries, of $1.2 million and $1.7 million for the three months and year ended June 30, 2016, respectively. Loans classified as substandard and doubtful decreased $10.5 million to $25.1 million at June 30, 2017 from $35.6 million at June 30, 2016.

Noninterest income increased by $112,000 and $2.1 million to $647,000 and $4.1 million for the three months and year ended June 30, 2017, respectively, compared to the same periods in 2016. The $112,000 increase in the three month period ended June 30, 2017 was primarily the result of gains on the sale of foreclosed real estate. The $2.1

million increase in the year ended June 30, 2017 was primarily the result of the receipt of $1.6 million in settlement on a loancharged-off by CMS Bank before the 2015 merger, additional bank owned life insurance income, higher fees and service charges and gains on the sale of foreclosed real estate.

Noninterest expense increased $4.6 million and $4.2 million to $12.9 million and $34.4 million for the three months and year ended June 30, 2017, respectively, compared to the same periods in 2016. These increases were caused primarily by the $5.0 million contribution to the PCSB Community Foundation in the fourth fiscal quarter of 2017. Additionally, in the year ended June 30, 2017 the Company recorded a nonrecurring $919,000 reduction in salaries and benefits expense from the curtailment of the defined benefit pension plan. Excluding the impact of the charitable foundation contribution, noninterest expense for the three months ended June 30, 2017 would have decreased $355,000, primarily due to decreases of $629,000 in merger-related expenses, $188,000 in occupancy and equipment expenses and $138,000 in FDIC assessments, partially offset by increases of $345,000 in salaries and benefits and $190,000 in other operating expenses. Excluding the impact of the curtailment and charitable foundation contribution, noninterest expense for the year ended June 30, 2017 increased $85,000, which was primarily due to increases of $859,000 in salaries and benefits (excluding curtailment), $742,000 in occupancy and equipment expenses, and $141,000 in advertising, partially offset by decreases of $790,000 inmerger- related expenses, $336,000 in professional fees, $330,000 in FDIC assessments and $134,000 in postage and supplies expense. The increases in salaries and benefits for both periods were due primarily to an increase in retirement expenses, including ESOP expense which commenced in April 2017. The increase in occupancy and equipment for the year ended June 30, 2017 was due primarily to a $521,000 impairment charge on an operating lease. The decreases in professional fees were due primarily to the Bank hiring consultants in the 2016 periods to assist with the implementation of the internal control requirements of the FDIC Improvement Act (“FDICIA”).

The Company recorded an income tax benefit of $1.0 million for the three months ended June 30, 2017 and income tax expense of $1.3 million for the year ended June 30, 2017, compared to an income tax benefit of $181,000 for the three months ended June 30, 2016 and income tax expense of $1.1 million for the year ended June 30, 2016. The effective income tax rate was 28.2% and 27.9% for the years ended June 30, 2017 and 2016, respectively.

Balance Sheet Summary

Total assets increased $164.4 million to $1.4 billion at June 30, 2017 from $1.3 billion at June 30, 2016. This increase was primarily due to increases of $112.4 million in total investment securities, $27.3 million in net loans receivable, $18.9 million in cash and cash equivalents, and $2.2 million in bank premises and equipment. The $112.4 million increase in total investment securities was primarily due to the purchase of investment securities funded by the conversion proceeds. The $27.3 million increase in net loans was primarily due to an increase of $51.8 million in commercial mortgage loans, partially offset by decreases of $8.3 million in residential mortgage loans, $7.3 million in commercial loans, $3.2 million in other loans secured, $2.7 million in consumer and installment loans, and $2.6 million in construction loans.

Total liabilities decreased $5.5 million to $1.1 billion at June 30, 2017 from $1.2 billion at June 30, 2016. This decrease was primarily due to a $24.2 million decrease in total deposits, partially offset by a $22.5 million increase in advances from the FHLB. The $24.2 million decrease in total deposits was caused by $23.8 million in deposits being used to purchase stock in the offering and a $32.3 million decrease in certificates of deposit, partially offset by a $31.9 million increase in core deposit accounts. The Bank’s strategy has been to focus on attracting lower cost checking accounts while allowing higher cost certificates of deposit to roll off.

Total stockholders’ equity increased $169.9 million to $279.8 million at June 30, 2017 from $109.9 million at June 30, 2016. This increase was primarily due to net conversion proceeds of $163.5 million, net income of $3.2 million and a $2.8 million decrease in accumulated other comprehensive loss. At June 30, 2017 the Company’s book value per share and tangible book value per share were $15.41 and $15.04, respectively. At June 30, 2017, the Bank was considered “well capitalized” under applicable regulatory guidelines.
