WVS FINANCIAL CORP. ANNOUNCES INCREASED NET INCOME AND EARNINGS PER

SHARE FOR THE THREE AND NINE MONTHS ENDED MARCH 31, 2018

Pittsburgh, PA — WVS Financial Corp. (NASDAQ: WVFC), the holding company for West View Savings Bank, today reported net income of $634 thousand or $0.35 per diluted share, for the three months ended March 31, 2018 as compared to $426 thousand or $0.23 per diluted share for the same period in 2017. The $208 thousand increase in net income during the three months ended March 31, 2018 was primarily attributable to a $194 thousand increase in net interest income, a $5 thousand decrease in provisions for loan losses and a $30 thousand decrease in income tax expense. The increase in net interest income during the three months ended March 31, 2018 was attributable to a $524 thousand increase in interest income, which was partially offset by a $330 thousand increase in interest expense. The increase in interest income was primarily attributable to higher average yields on the Company’s investment and mortgage-backed securities as well as an increase in average loan balances when compared to the same period in 2017. The increase in interest expense was primarily attributable to higher rates paid on Federal Home Loan Bank (“FHLB”) borrowings and time deposits and higher average balances of FHLB borrowings outstanding during the three months ended March 31, 2018, when compared to the same period in 2017. The decrease in the provision for loan losses was primarily attributable to lower originations of single-family loans during the quarter ended March 31, 2018, partially offset by an increase in the Company’s ALLL reserve factor for the single family-permanent loan segment, when compared to the same period in 2017. The decrease in income tax expense for the quarter ended March 31, 2018 when compared to the same period of 2017 reflects the reduced federal corporate tax rate offset by higher levels of taxable income.

Net income for the nine months ended March 31, 2018 totaled $1.5 million or $0.84 per diluted share, as compared to $1.2 million or $0.65 per diluted share for the same period in 2017. The $314 thousand increase in net income during the nine months ended March 31, 2018 was primarily attributable to a $524 thousand increase in net interest income and a $28 thousand decrease in provisions for loan losses, which were partially offset by an increase of $239 thousand in income tax expense. The increase in net interest income during the nine months ended March 31, 2018 was attributable to a $1.4 million increase in interest income, which was partially offset by an $881 thousand increase in interest expense. The increase in interest income was primarily attributable to higher average yields on the Company’s investment and mortgage-backed securities as well as an increase in average loan balances when compared to the same period in 2017. Also contributing to the increase in interest income for the nine months ended 2018 were higher average balances and yields attributable to dividends received on FHLB stock. The increase in interest expense was primarily attributable to higher average market rates paid on FHLB borrowings and time deposits which were partially offset by lower average balances of FHLB long-term advances outstanding,

during the nine months ended March 31, 2018, when compared to the same period in 2017. The decrease in the provision for loan losses was primarily attributable to lower originations of single-family loans, which was partially offset by an increase in the Company’s ALLL reserve factor for the single family-permanent loan segment, during the nine months ended March 31, 2018 compared to the same period of 2017. The increase in income tax expense for the nine months ended March 31, 2018 when compared to the same period in 2017 was primarily the result of an additional $133 thousand federal income tax expense due to the write down of the Company’s net deferred tax assets associated with the Tax Cuts and Jobs Act of 2017 as well as higher taxable income. Partially offsetting the $133 write down and the higher taxable income was the reduced corporate federal tax rate effective January 1, 2018.
