WVS FINANCIAL CORP. ANNOUNCES INCREASED NET INCOME AND EARNINGS PER

SHARE FOR THE THREE AND NINE MONTHS ENDED MARCH 31, 2017

Pittsburgh, PA — WVS Financial Corp. (NASDAQ: WVFC), the holding company for West View Savings Bank, today reported net income of $426 thousand or $0.23 per diluted share, for the three months ended March 31, 2017 as compared to $329 thousand or $0.17 per diluted share for the same period in 2016. The $97 thousand increase in net income during the three months ended March 31, 2017 was primarily attributable to a $108 thousand increase in net interest income, a $43 thousand decrease in non-interest expense, and a $6 thousand decrease in provisions for loan losses, which were partially offset by a $59 thousand increase in income tax expense. The increase in net interest income during the three months ended March 31, 2017 was attributable to a $193 thousand increase in interest income, which was partially offset by an $85 thousand increase in interest expense. The increase in interest income was primarily attributable to higher average balances of loans outstanding, when compared to the same period in 2016. The increase in interest expense was primarily attributable to higher average rates paid on FHLB borrowings and time deposits during the three months ended March 31, 2017, when compared to the same period in 2016. The decrease in non-interest expense was primarily attributable to lower FDIC deposit insurance premiums and legal expenses during the quarter ended March 31, 2017, when compared to the same period in 2016. The decrease in the provision for loan losses was primarily attributable to a decrease in non-residential loan balances which were partially offset by an increase in the Company’s single-family loan portfolio.

Net income for the nine months ended March 31, 2017 totaled $1.219 million or $0.65 per diluted share, as compared to $933 thousand or $0.49 per diluted share for the same period in 2016. The $286 thousand increase in net income during the nine months ended March 31, 2017 was primarily attributable to a $304 thousand increase in net interest income, an $80 thousand decrease in non-interest expense, and an $18 thousand decrease in provisions for loan losses, which were partially offset by a $60 thousand decrease in non-interest income. The increase in net interest income during the nine months ended March 31, 2017 was attributable to a $527 thousand increase in interest income, which was partially offset by a $223 thousand increase in interest expense. The increase in interest income was primarily attributable to higher average balances of loans outstanding, when compared to the same period in 2016. The increase in interest expense was primarily attributable to higher average rates paid on FHLB borrowings, which were partially offset by lower average balances of FHLB borrowings, during the nine months ended March 31, 2017, when compared to the same period in 2016. The decrease in non-interest expense was primarily attributable to decreases in FDIC insurance premiums, legal and compensation expenses which were partially offset by higher data processing and charitable contribution expenses during the nine months ended March 31, 2017, when compared to the same period in 2016. The decrease in non-interest income for the nine months ended March 31, 2017 was primarily attributable to a realized loss on a trading security and the absence of investment securities gains, when compared to the same period in 2016. The decrease in the provision for loan losses was primarily attributable to a decrease in non-residential loan balances which were partially offset by an increase in the Company’s single-family loan portfolio.
