FOR IMMEDIATE RELEASE

OCEANFIRST FINANCIAL CORP.

ANNOUNCES QUARTERLY AND ANNUAL

FINANCIAL RESULTS

TOMS RIVER, NEW JERSEY, January 23, 2013…OceanFirst Financial Corp. (NASDAQ:“OCFC”), the holding company for OceanFirst Bank (the “Bank”), today announced that diluted earnings per share amounted to $1.12 for the year ended December 31, 2012, as compared to $1.14 for the prior year. For the quarter ended December 31, 2012, diluted earnings per share amounted to $0.23, as compared to $0.30 for the corresponding prior year period. Diluted earnings per share for the quarter and the year ended December 31, 2012 were adversely impacted by an additional provision for loan losses of $1.8 million relating to the impact of superstorm Sandy. Additionally, diluted earnings per share for the year ended December 31, 2012 was adversely impacted by $687,000 in net severance expense as previously reported in the third quarter of 2012. These items adversely impacted diluted earnings per share by $.06 and $.09, respectively, for the quarter and the year ended December 31, 2012.

Additional highlights for the quarter and year included:

The Company also announced that the Board of Directors declared its sixty-fourth consecutive quarterly cash dividend on common stock. The dividend for the quarter ended December 31, 2012 of $0.12 per share will be paid on February 15, 2013, to shareholders of record on February 4, 2013.

Chairman and CEO John R. Garbarino observed, “We are pleased to continue to report solid earnings despite a sizeable provision related to the devastation experienced in our area from superstorm Sandy. During the quarter, we also announced a 5% share repurchase plan, renewing the plan previously adopted in the fourth quarter of 2011 which remains an effective means of returning value to our shareholders”.

Results of Operations

Net income for the three months ended December 31, 2012 decreased to $4.0 million, or $0.23 per diluted share, as compared to net income of $5.5 million, or $0.30 per diluted share for the corresponding prior year period. For the year ended December 31, 2012, net income totaled $20.0 million, or $1.12 per diluted share, as compared to net income of $20.7 million, or $1.14 per diluted share, for the prior year. Net income for the quarter and the year ended December 31, 2012 was adversely impacted by the additional loan loss provision relating to

superstorm Sandy of $1.8 million, or $1.1 million, net of tax benefit. Additionally, net income for the year ended December 31, 2012 was adversely impacted by $687,000, or $430,000, net of tax benefit, in net severance expense recognized in the third quarter of 2012. Excluding these items, net income benefited from a decrease in the provision for loan losses (after excluding the impact of superstorm Sandy), an increase in other income, a decrease in operating expenses (after excluding the severance expense) and a reduction in average shares outstanding.

Net interest income for the quarter and year ended December 31, 2012 decreased to $18.0 million and $73.5 million, respectively, as compared to $19.3 million and $77.3 million, respectively, in the same prior year periods, reflecting a lower net interest margin partly offset by greater interest-earning assets. The net interest margin decreased to 3.29% and 3.37%, respectively, for the quarter and year ended December 31, 2012, from 3.53% and 3.59%, respectively, in the same prior year periods due to a change in the mix of average interest-earning assets from higher-yielding loans receivable into lower-yielding short-term investments and investment and mortgage-backed securities available for sale. High loan refinance volume also caused yields on loans and mortgage-backed securities to trend downward. The yield on average interest-earning assets decreased to 3.87% and 4.02%, respectively, for the quarter and year ended December 31, 2012, as compared to 4.29% and 4.43%, respectively, for the same prior year periods. For the quarter and year ended December 31, 2012, the yield on loans receivable benefited from commercial loan prepayment fees of $163,000 and $495,000, respectively, which increased the yield on interest-earning assets and the net interest margin by 3 basis points and 2 basis points, respectively. The cost of average interest-bearing liabilities decreased to 0.67% and 0.75%, respectively, for the quarter and year ended December 31, 2012, as compared to 0.86% and 0.95%, respectively, in the same prior year periods. Average interest-

earning assets increased $6.6 million, or 0.3%, and $28.0 million, or 1.3%, respectively, for the quarter and year ended December 31, 2012, as compared to the same prior year periods. The increases in average interest-earning assets were primarily due to the increases in average investment and mortgage-backed securities, which collectively increased $42.2 million and $70.0 million, for the quarter and year ended December 31, 2012, respectively, and the increase in average short-term investments which increased $12.2 million and $23.3 million, for the quarter and year ended December 31, 2012, respectively. The growth in interest-earning assets was primarily funded by an increase in average transaction deposits and non-interest-bearing deposits, partly offset by a decrease in average time deposits and borrowed funds.

For the quarter and year ended December 31, 2012, the provision for loan losses was $3.1 million and $7.9 million, respectively, as compared to $2.0 million and $7.8 million, respectively, for the corresponding prior year periods. The increases were due to the additional provision of $1.8 million relating to the impact of superstorm Sandy. Excluding this additional provision, the provision for loan losses decreased $700,000 and $1.7 million for the quarter and year ended December 31, 2012, respectively, partly due to a reduction in both non-performing loans and loans receivable, net at December 31, 2012 as compared to December 31, 2011.

Other income increased to $4.5 million and $18.2 million, respectively, for the quarter and year ended December 31, 2012, as compared to $4.2 million and $15.3 million, respectively, in the same prior year periods due to higher fees and service charges, an improvement in the net gain (loss) from other real estate operations and, for the year ended December 31, 2012, an increase in the net gain on the sale of loans. For the year ended December 31, 2012, the Company recognized a gain of $226,000 on sale of equity securities as compared to the recognition of an other-than-temporary impairment loss on equity securities of $148,000 for the

year ended December 31, 2011. For the year ended December 31, 2012, the net gain on the sale of loans increased $1.0 million, due to an increase in loan sale volume and strong gain on sale margins. However, the net gain on the sale of loans for the quarter and year ended December 31, 2012 was reduced by an increase of $400,000 and $750,000, respectively, in the reserve for repurchased loans. For the quarter and year ended December 31, 2012, fees and service charges increased $190,000 and $723,000, respectively, primarily due to increases in trust and bankcard services revenue. Finally, the net gain (loss) from other real estate operations improved $189,000 and $613,000 for the quarter and year ended December 31, 2012, respectively, as compared to the same prior year periods.

Operating expenses increased by $223,000, to $13.2 million, and by $227,000, to $52.9 million, respectively, for the quarter and year ended December 31, 2012, as compared to $13.0 million and $52.7 million, respectively, for the corresponding prior year periods. Excluding the $687,000 severance related expenses included in compensation and employee benefits, net of expense savings, for the year ended December 31, 2012, operating expenses decreased by $460,000 as compared to the corresponding prior year period. For the quarter and year ended December 31, 2012, compensation and employee benefits costs, net of the severance cost, decreased by $153,000, or 2.3%, to $6.6 million for the quarter ended December 31, 2012 and by $1.2 million, or 4.1%, to $26.9 million for the year ended December 31, 2012. The decreases were due to lower incentive plan expense of $477,000 and $640,000, respectively, for the quarter and year ended December 31, 2012. The decrease for the year ended December 31, 2012 also benefited by $611,000 due to the increase in mortgage loan closings from prior year levels. Higher loan closings in the current period increased deferred loan expense, net of sales commissions to mortgage loan representatives, which is reflected as a decrease in compensation

expense. Additionally, Federal deposit insurance expense decreased by $440,000 for the year ended December 31, 2012 as compared to the prior year due to a lower assessment rate and a change in the assessment methodology from deposit-based to a total liability-based assessment. These changes to Federal deposit insurance affected the expense for the first six months of 2012 as compared to the same prior year period.

The provision for income taxes was $2.1 million and $10.9 million, respectively, for the quarter and year ended December 31, 2012, as compared to $3.0 million and $11.5 million, respectively, for the same prior year periods. The effective tax rate was 34.5% and 35.3%, respectively, for the quarter and year ended December 31, 2012, as compared to 35.5% and 35.6%, respectively, in the same prior year periods.

Financial Condition

Total assets decreased by $32.9 million to $2,269.2 million at December 31, 2012, from $2,302.1 million at December 31, 2011. Cash and due from banks decreased by $15.0 million, to $62.5 million at December 31, 2012, as compared to $77.5 million at December 31, 2011. The cash and due from banks was invested in investment and mortgage-backed securities available for sale, which collectively increased by $17.2 million, to $547.4 million at December 31, 2012, as compared to $530.2 million at December 31, 2011. Loans receivable, net, decreased by $39.8 million, to $1,523.2 million at December 31, 2012 from $1,563.0 million at December 31, 2011 primarily due to prepayments and sale of newly originated 30-year fixed-rate one-to-four family loans. Bank Owned Life Insurance increased by $11.2 million at December 31, 2012 as compared to December 31, 2011 primarily due to an additional investment during the third quarter of 2012.

Deposits increased by $13.6 million, to $1,719.7 million at December 31, 2012, from $1,706.1 million at December 31, 2011. Federal Home Loan Bank advances decreased $41.0 million, to $225.0 million at December 31, 2012, from $266.0 million at December 31, 2011 due to excess liquidity and cash flows from loans receivable. Stockholders’ equity increased to $219.8 million at December 31, 2012, as compared to $216.8 million at December 31, 2011, primarily due to net income and a reduction in accumulated other comprehensive gain (loss), partly offset by the cash dividend on common stock and by the repurchase of 843,370 shares of common stock for $11.9 million. At December 31, 2012, there were 834,784 shares remaining to be repurchased under the stock repurchase program adopted in the fourth quarter of 2012.

Asset Quality

The Company’s non-performing loans totaled $43.4 million at December 31, 2012, a $634,000 decrease from $44.0 million at December 31, 2011. Net loan charge-offs decreased to $5.6 million for the year ended December 31, 2012, as compared to $9.2 million for the corresponding prior year period. During the fourth quarter of 2011, the Company modified its charge-off policy on problem loans secured by real estate which accelerated the recognition of loan charge-offs. The Company now takes charge-offs in the period the loan, or portion thereof, is deemed uncollectable, generally after the loan becomes 120 days delinquent and a recent appraisal is received which reflects a collateral shortfall. Previously, specific valuation reserves were established until the loan charge-off was recorded upon final resolution of the collateral. The change in the charge-off policy resulted in additional charge-offs in the fourth quarter of 2011 of $5.7 million.

On October 29 and 30, 2012 the primary market area of the Bank was adversely impacted by superstorm Sandy. The storm disrupted operations for most businesses in the area and caused substantial property damage. The Bank provided payment deferrals to residential borrowers impacted by the storm for two months without penalty. An additional extension is considered if adequate documentation is presented. At December 31, 2012, 120 residential loan borrowers requested a payment deferment. For this pool of borrowers, the outstanding principal balance is $28.8 million; the average loan size is $240,000; the weighted average loan-to-value ratio is 61% based on appraised values at the time of origination or a more recent valuation, if available; and 69% of these loans are located in a flood zone. The Bank requires flood insurance on all properties in a flood zone. The Bank’s practice has been to follow-up with all borrowers who received a storm-related payment delay after 45 days to determine the extent of the financial impact caused by the storm and to establish a repayment plan. Through January 19, 2013 the Bank had followed-up with 87 borrowers with principal balances of $19.2 million. The result was as follows:

For the 12 borrowers experiencing financial hardship, the Bank evaluated its security position by aggregating estimated land value and flood insurance for each property. The weighted average loan-to-value ratio for these loans, using only estimated land value and anticipated flood insurance was 65% and no individual loan-to-value ratio exceeded 88%.

The Bank has also contacted most of its commercial loan borrowers. At this time, three commercial real estate borrowers with a combined total outstanding loan balance of $3.6 million have reported substantial property damage. Each of these loans has continued to perform according to their original terms and maintains a loan-to-value ratio prior to the impact of Sandy of less than 25%, based on appraisal values at the time of origination or a more recent valuation, if available. Additionally, six commercial loan borrowers requested short-term payment relief due to the impact of the storm. The Bank has allowed these borrowers to defer principal payments for up to 90 days and all of these borrowers are performing according to the revised terms.

The Bank has evaluated the impact of the storm relative to the adequacy of the allowance for loan losses. Based on the Bank’s evaluation, as described above, there were no loan charge-offs or specific losses identified. Although the ultimate amount of loan losses relating to the storm is uncertain and difficult to predict, and information continues to be gathered, the Bank recorded an additional provision for loan losses of $1.8 million for the quarter and year ended December 31, 2012, solely related to the impact of superstorm Sandy.

The reserve for repurchased loans, which is included in other liabilities in the Company’s consolidated statements of financial condition, was $1.2 million at December 31, 2012, a $498,000 increase from December 31, 2011 due to an additional provision for repurchased loans of $750,000, primarily resulting from an increase in repurchase requests, partly offset by a loss of $252,000 on a single loan repurchased. At December 31, 2012, there were 12 outstanding loan repurchase requests which the Company is disputing, on loans with a total principal balance of $3.6 million, as compared to 4 outstanding loan repurchase requests with a principal balance of $1.2 million at December 31, 2011.
