PRESS RELEASE

Territorial Bancorp Inc.

Announces Fourth Quarter 2012 Results

Honolulu, Hawaii, February 4, 2013 - Territorial Bancorp Inc. (NASDAQ: TBNK) (the “Company”), headquartered in Honolulu, Hawaii, the holding company parent of Territorial Savings Bank, announced net income of $3.8 million or $0.38 per basic and $0.37 per diluted share for the three months ended December 31, 2012, compared to $3.4 million or $0.33 per basic and diluted share for the three months ended December 31, 2011. For the year ended December 31, 2012, the Company earned $14.8 million or $1.47 per basic share and $1.45 per diluted share, compared to $12.8 million for the year ended December 31, 2011, or $1.19 per basic share and $1.17 per diluted share. The Company’s earnings grew by 16.0% in 2012. The increase in earnings for the fourth quarter and for the year was primarily due to gains on sale of investment securities and higher mortgage loan production that increased interest income and generated greater gains on sale of loans.

The Company also announced that its Board of Directors today approved a quarterly cash dividend on its common stock of $0.12 per share. The dividend is expected to be paid on March 4, 2013 to stockholders of record as of February 18, 2013.

Allan Kitagawa, Chairman and Chief Executive Officer, said “This past year we were successful in increasing our residential mortgage loan production. Our staff was able to close a record number of mortgage loans. As a result, our loan portfolio grew despite a significant increase in prepayments of existing loans due to the drop in mortgage rates in 2012. We continue to improve shareholder returns by repurchasing stock and paying dividends. In December of 2012, because the future tax rate on dividends could have increased dramatically, we declared a special dividend of $0.10 per share. When added to our four quarterly dividends, we paid our shareholders a total of $0.54 per share during 2012. We felt that this was an opportunity to thank our shareholders who have supported us over the past three and one-half years. I am pleased to announce that because of our strong performance we will be paying a quarterly dividend of $0.12 per share.”

Interest Income

For the three months ended December 31, 2012 and 2011, net interest income was $12.3 million and $13.1 million, respectively. The decrease in net interest income was due to a $1.7 million decrease in interest and dividend income earned which was partially offset by an $820,000 decrease in interest expense. Total interest and dividend income was $14.2 million for the three months ended December 31, 2012 compared to $15.9 million

for the three months ended December 31, 2011. The decrease in interest and dividend income occurred primarily due to a decline in interest earned on investment securities which totaled $4.9 million for the three months ended December 31, 2012 compared to $6.7 million for the three months ended December 31, 2011. This decrease resulted from a $40.9 million reduction in the Bank’s investment portfolio, principally due to an increase in repayments. This decrease was offset by an increase of $160,000 in interest earned on loans and other investments. Total interest expense decreased by $820,000 due to the continuation of the lower interest rate environment and the payoff of securities sold under agreements to repurchase.

Interest Expense and Provision for Loan Losses

Total interest expense decreased to $1.9 million for the three months ended December 31, 2012 compared to $2.7 million for the three months ended December 31, 2011. The decrease in interest expense is primarily due to a $369,000 reduction of interest expense on deposits and a $450,000 reduction of interest expense on securities sold under agreements to repurchase. Provision for loan losses decreased to $243,000 for the three months ended December 31, 2012 compared to $335,000 for the three months ended December 31, 2011.

Noninterest Income

Noninterest income was $2.3 million for the three months ended December 31, 2012 compared to $1.6 million for the three months ended December 31, 2011. The increase in noninterest income was primarily due to a $558,000 increase in gain on sale of loans created by higher loan production during the quarter and a $194,000 increase in gain on sale of investment securities.

Noninterest Expense

Noninterest expense increased to $8.7 million for the three months ended December 31, 2012 as compared to $8.4 million for the three months ended December 31, 2011. The increase in noninterest expense was primarily due to higher salary and employee benefit expense, occupancy expense and other general and administrative expenses.

Year Ended December 31, 2012 Results

For the year ended December 31, 2012 net interest income was $50.9 million compared to $51.4 million for the year ended December 31, 2011. Total interest and dividend income decreased to $60.1 million for the year ended December 31, 2012 from $62.7 million for the year ended December 31, 2011 because of an increase in repayments on higher yielding loans and securities. Total interest expense decreased to $9.2 million for the year ended December 31, 2012 from $11.3 million for the year ended December 31, 2011, due to decreases in interest expense on deposits and interest paid on securities sold

under agreements to repurchase. Provision for loan losses decreased to $415,000 for the year ended December 31, 2012 compared to $418,000 for the year ended December 31, 2011.

Noninterest income was $7.1 million for the year ended December 31, 2012 compared to $5.1 million for the year ended December 31, 2011. This increase in noninterest income was primarily due to higher mortgage loan production that generated greater gain on sale of loans which increased to $2.4 million for the year ended December 31, 2012, compared to $711,000 for the year ended December 31, 2011 and gain on sale of investment securities which rose to $1.2 million for the year ended December 31, 2012 compared to $451,000 for the year ended December 31, 2011. These increases in noninterest income were offset somewhat by a total decrease of $500,000 in service fees on loan and deposit accounts and other noninterest income.

Noninterest expense was $34.4 million for the year ended December 31, 2012 compared to $34.7 million for the year ended December 31, 2011. The decrease in noninterest expense was primarily due to a $1.0 million decrease in compensation and employee benefits and a $98,000 decrease in federal deposit insurance premiums. A significant portion of the decrease in compensation and employee benefits was due to $696,000 of stock benefit plan expenses which the Company recognized in 2011 due to the death of a director which resulted in the immediate vesting of stock awards. These decreases in noninterest expense were offset by increases of $321,000 on loss of extinguishment of debt, $258,000 in occupancy expense, and $237,000 in other general and administrative expenses. The loss on extinguishment of debt occurred when the Bank paid off $25.0 million of higher costing borrowings.

Assets and Equity

Total assets grew to $1.575 billion at December 31, 2012 from $1.538 billion at December 31, 2011. Cash and cash equivalents increased to $182.8 million at December 31, 2012 from $131.9 million at December 31, 2011. Investment securities held to maturity decreased to $554.7 million as of December 31, 2012 from $653.9 million at December 31, 2011 as repayments and sales exceeded the amount of securities purchased. Loans receivable grew to $774.9 million at December 31, 2012 from $688.1 million at December 31, 2011 due to an increase in residential mortgage loan originations. The growth in loans receivable was funded primarily by a $71.7 million increase in deposits. Deposits increased to $1.238 billion at December 31, 2012 from $1.166 billion at December 31, 2011. Total stockholders’ equity increased to $219.0 million at December 31, 2012 from $214.0 million at December 31, 2011. The growth in stockholders’ equity was primarily due to the Company’s earnings for the year ended December 31, 2012, which were offset by the cost of shares repurchased under the Company’s stock buyback program and dividend payments. The Board of Directors has authorized three repurchase programs. Through the end of December 31, 2012, the Company had repurchased a total of 1,684,171 shares, compared to 1,336,975 shares as of December 31, 2011.

Asset Quality

Total delinquent loans 90 days or more past due and not accruing totaled $2.0 million (8 loans) at December 31, 2012, compared to $2.3 million (9 loans) at December 31, 2011. Non-performing assets totaled $4.4 million at December 31, 2012 compared to $3.3 million at December 31, 2011. The increase in nonperforming assets occurred after we classified $2.2 million of existing loans as nonaccrual. However, the ratio of non-performing assets to total assets of 0.28% at December 31, 2012 remains one of the lowest in the country. The allowance for loan losses at December 31, 2012 was $1.7 million and represented 0.22% of total loans. At December 31, 2011, the allowance for loan losses was $1.5 million and represented 0.22% of total loans.
