WVS FINANCIAL CORP. ANNOUNCES INCREASED NET INCOME AND EARNINGS

PER SHARE FOR THE THREE MONTHS ENDED SEPTEMBER 30, 2017

Pittsburgh, PA — WVS Financial Corp. (NASDAQ: WVFC), the holding company for West View Savings Bank, today reported net income of $502 thousand or $0.28 per diluted share, for the three months ended September 30, 2017 as compared to $398 thousand or $0.21 per diluted share for the same period in 2016. The $104 thousand increase in net income during the three months ended September 30, 2017 was primarily attributable to a $177 thousand increase in net interest income, a $42 thousand decrease in non-interest expense, and an $11 thousand decrease in the provision for loan losses, which were partially offset by a $15 thousand decrease in non-interest income and a $111 increase in income tax expense. The increase in net interest income during the three months ended September 30, 2017 was attributable to a $448 thousand increase in interest income, which was partially offset by a $271 thousand increase in interest expense. The increase in interest income for the quarter ended September 30, 2017 was primarily attributable to higher average balances of loans outstanding and investment securities as well as higher yields on mortgage backed securities. The higher average balance of loans outstanding was attributable to increased loan originations in excess of repayments, and were funded primarily from repayments on the Company’s Government agency mortgage-backed securities. The increase in the average balance of investment securities was primarily attributable to the purchase of investment grade floating rate corporate bonds which were primarily funded with FHLB advances and deposits. The increase in interest expense during the three months ended September 30, 2017, when compared to the same period in 2016, was primarily attributable to higher market interest rates paid on FHLB short-term advances and FHLB long-term variable rate advances, and higher average balances of FHLB short-term advances, which were partially offset by lower average balances of FHLB long-term fixed and variable rate advances. The decrease in non-interest expense was primarily attributable to decreases in ATM network and telephone expenses in the three months ended September 30, 2017 when compared to the same period in 2016. The decrease in non-interest income was primarily attributable to lower transaction account service charges and an $8 thousand other than temporarily impairment loss on securities for the quarter ended September 30, 2017, when compared to the same period in 2016. The increase in income tax expense for the three months ended September 30, 2017 was primarily due to higher levels of taxable income, when compared to the same period in 2016. The decrease in the provision for loan losses was primarily due to lower average volumes of loans within the land acquisition and development segment in the Company’s loan portfolio partially offset by an increase in the Company’s single-family loan portfolio.
