FOR IMMEDIATE RELEASE

NORTHFIELD BANCORP, INC. ANNOUNCES RECORD RESULTS FOR 2011

NOTABLE ITEMS INCLUDE:

AVENEL, NEW JERSEY, FEBRUARY 8, 2012.…NORTHFIELD BANCORP, INC. (NasdaqGS:NFBK-News), the holding company for Northfield Bank, reported basic and diluted earnings per common share of $0.10 and $0.42 for the quarter and year ended December 31, 2011, respectively, as compared to $0.09 and $0.33 for the quarter and year ended December 31, 2010, respectively. Earnings for the quarter and year ended December 31, 2011, included an after-tax bargain purchase gain of $3.6 million, or $0.09 per share, related to an FDIC-assisted transaction completed in October 2011. The Company also transferred $7.4 million of loans to held-for-sale resulting in a charge-off, and related provision for loan losses of $4.0 million ($2.4 million after-tax), or $0.06 per share for the quarter and year ended December 31, 2011. Earnings for the year ended December 31, 2010 included after tax expenses of approximately $1.2 million, or $0.03 per share, related to the Company’s postponed second step offering as well as a $0.02 per share benefit related to a change in New York State and City tax law related to bad debt reserves.

John W. Alexander, Chairman and Chief Executive Officer of Northfield commented, “We are pleased to report that in 2011 Northfield earned the highest net income in the company’s 124 year history and reported our highest annual earnings per share as a public company. We again experienced strong loan growth which allowed us to manage our net interest margin in a low rate environment by continuing to shift our asset mix from lower yielding investments to loans. We have expanded our retail network to 23 branches through de novo branching and through an FDIC-assisted acquisition which was completed in the fourth quarter. Our expansion continues with six branches in various stages of construction – three in Brooklyn, one in Staten Island, and two in New Jersey. We have maintained strong liquidity and have made great strides in deploying our capital with our overall capital level standing at 16.1% at year end. This capital deployment has been accomplished through internal growth and our acquisition, the return of capital through cash dividends, and the adoption and implementation of our third stock repurchase program. Prior to the date of this earnings release, the Board declared a $0.06 dividend, its fourteenth consecutive quarterly dividend.”

Continuing, Mr. Alexander added, “We were able to sustain our strong performance while also making significant progress in reducing the level of non-performing loans. We continue to work with borrowers, when possible, to bring loans back to a performing status. When workouts are not feasible, we look to maximize recovery while minimizing cost and distractions to our core business. Given the length of time, cost, and resources necessary to collect, management identified $7.4 million in loans that it decided to transfer to held-for-sale in the fourth quarter of 2011. These loans were charged down to their estimated fair value of $3.4 million.”

Basis of Discussion and Analysis

During the fourth quarter of 2011, the Company purchased a loan portfolio, with deteriorated credit quality, from the Federal Deposit Insurance Corporation, herein referred to as purchased credit-impaired loans, and transferred certain loans, previously originated and designated by the Company as held-for-investment, to held-for-sale. The accounting and reporting for these loans differs substantially from those loans originated and classified by the Company as held-for-investment. For purposes of reporting, discussion and analysis, management has classified its loan portfolio into three categories: (1) loans originated by the Company and held-for-sale, which are carried at the lower of cost or estimated fair value, less costs to sell, and therefore have no associated allowance for loan losses, (2) Purchased credit-impaired (PCI) loans, which are held-for-investment, and initially valued at estimated fair value on the date of acquisition, with no initial related allowance for loan losses, and (3) Originated loans held-for-investment, which are carried at amortized cost, less net charge-offs and the allowance for loan losses.

Financial Condition

Total assets increased $129.8 million, or 5.8%, to $2.38 billion at December 31, 2011, from $2.25 billion at December 31, 2010. The increase was primarily attributable to increases in net loans held-for-investment of $241.9 million, or 30.0% and cash and cash equivalents of $21.4 million. This increase was partially offset by a decrease in securities available for sale of $145.6 million.

Originated loans held-for-investment, net, totaled $985.9 million at December 31, 2011, as compared to $827.6 million at December 31, 2010. The increase was primarily in multi-family real estate loans, which increased $174.7 million, or 61.6%, to $458.3 million at December 31, 2011, from $283.6 million at December 31, 2010. Insurance premium loans increased $14.6 million, or 32.7%, to $59.1 million and home equity loans increased $1.5 million, or 5.5%, to $29.7 million at December 31, 2011. These increases were partially offset by the transfer of $7.4 million of originated loans held-for-investment, at amortized cost, to held-for-sale, at an estimated fair value, less costs to sell, of $3.4 million, resulting in a charge-off to the allowance for loan losses of $4.0 million. Originated loans held-for-investment also decreased due to decreases in one-to-four family residential of $5.4 million, commercial real estate of $12.5 million, land and construction of $11.9 million, and commercial and industrial loans of $4.3 million. Currently, management is focused on originating multi-family loans, with less emphasis on other loan types.

On October 14, 2011, the Company purchased PCI loans of approximately $132.4 million, based on the recorded principal balance, net of deferred fees and costs, of a failed institution, as part of a Federal Deposit Insurance Corporation-assisted transaction. Management recorded PCI loans at their estimated fair value of $91.9 million at the date of acquisition. The Company accounts for PCI loans utilizing generally accepting accounting principles applicable to loans acquired with deteriorated credit quality. At the purchase date, the Company estimated the fair value of PCI loans by projecting future cash flows of PCI loans (both amount and timing) and discounted the estimated future cash flows utilizing a current market discount rate, considering current risk-free rates of returns, adjusted for, among other things, credit, liquidity, and prepayment factors. The difference between the Company’s initial carrying value of PCI loans of $91.9 million, and the estimated future cash flows of $135.8 million, represents $43.9 million of future accretable yield that is expected to be recorded as interest income in future periods over the life of the underlying loans. To the extent actual or expected future cash flows are favorable as compared to the Company’s original estimates, accretable yield will increase, and the Company will recognize increased interest income over the remaining life of the loan. To the extent actual or expected future cash flows are unfavorable as compared to the Company’s original estimates, the Company will reduce the carrying value of the PCI loans, through the provision for loan losses, such that discount rate applied at the date of acquisition will remain unchanged. The following details the accretable yield for the quarter and year ended December 31, 2011:

The Company’s securities portfolio totaled $1.1 billion at December 31, 2011, compared to $1.3 billion at December 31, 2010. At December 31, 2011, $1.0 billion of the portfolio consisted of residential mortgage-backed securities issued or guaranteed by Fannie Mae, Freddie Mac, or Ginnie Mae. The Company also held residential mortgage-backed securities not guaranteed by these three entities, referred to as “private label securities.” The private label securities had an amortized cost of $39.9 million and an estimated fair value of $40.5 million at December 31, 2011. In addition to the above mortgage-backed securities, the Company held $100.7 million in securities issued by corporate entities which were all rated investment grade at December 31, 2011, and $11.8 million of equity investments in mutual funds, which focus on investments that qualify under the Community Reinvestment Act and money market mutual funds.

Interest-bearing deposits in other financial institutions totaled $45.7 million at December 31, 2011, as compared to $34.0 million at December 31, 2010. The Company routinely maintains liquid assets in interest-bearing accounts in other well-capitalized financial institutions.

Total liabilities increased $143.8 million from December 31, 2010. The increase was primarily attributable to an increase in deposits of $120.7 million, or 8.8%, and an increase in borrowings of $90.7 million, or 23.2%, partially offset by a decrease of $70.7 million in amounts due to securities brokers for securities purchased but not settled at period end.

The increase in deposits for the year ended December 31, 2011 was due to an increase in transaction accounts of $196.7 million, or 40.8% as compared to December 31, 2010. This increase was partially offset by a decrease in certificates of deposit accounts (issued by the Bank) of $7.9 million, or 1.6%, from December 31, 2010 to December 31, 2011, a decrease in savings accounts of $3.1 million, or 0.9% as compared to December 31, 2010 and a decrease of $65.0 million in short-term certificates of deposit originated through the CDARS^® Network. Deposits originated through the CDARS^® Network totaled $3.4 million at December 31, 2011 and $68.4 million at December 31, 2010. The Company utilizes the CDARS^® Network as a cost effective alternative to other short-term funding sources. The increase in deposits was partially attributable to the FDIC- assisted transaction. The acquired deposits were approximately $109.5 million at December 31, 2011. The increase in borrowings was primarily the result of the Company taking advantage of the current lower interest rate market to reduce interest rate risk, partially offset by maturities during the year ended December 31, 2011. The decrease in due to securities brokers was the result of $70.7 million of security purchases occurring prior to December 31, 2010, and settling after year end, the Company had no such transactions at December 31, 2011.

Total stockholders’ equity decreased by $14.1 million to $382.7 million at December 31, 2011, from $396.7 million at December 31, 2010. The decrease was primarily due to $37.8 million in stock repurchases and the payment of approximately $3.7 million in cash dividends. These decreases were partially offset by net income of $16.8 million for the year ended December 31, 2011, and an increase of $3.4 million in additional paid-in capital primarily related to the recognition of compensation expense associated with equity awards, and an increase in accumulated other comprehensive income of $6.6 million, related primarily to increases in unrealized gains on securities available for sale, net of tax, due to a decrease in general market interest rates.

Northfield Bank’s (the Company’s wholly-owned subsidiary) Tier 1 (core) capital ratio was approximately 13.41%, at December 31, 2011. The Bank’s total risk-based capital ratio was approximately 24.69% at the same date. These ratios continue to significantly exceed the required regulatory capital ratios necessary to be considered “well capitalized” under current federal capital regulations. Northfield Bancorp, Inc.’s consolidated average total equity as a percentage of average total assets was 16.95% for the year ended December 31, 2011, as compared to 18.81% for the year ended December 31, 2010.

Asset Quality

Nonperforming Originated Loans (Held-for-Investment and Held-for-Sale)

Nonperforming originated loans totaled $43.9 million (4.3% of total loans held-for-investment and held-for-sale) at December 31, 2011, as compared to $53.4 million (5.5% of total loans) at September 30, 2011, $58.0 million (6.4% of total loans) at June 30, 2011, $56.7 million (6.6% of total loans) at March 31, 2011 and $60.9 million (7.4% of total loans) at December 31, 2010. The following table also shows, for the same dates, Troubled Debt Restructurings (TDR) on which interest is accruing, and accruing loans delinquent 30 to 89 days (dollars in thousands).

Total Non-Accruing Originated Loans

Total non-accruing loans decreased $15.5 million, to $43.8 million at December 31, 2011, from $59.3 million at December 31, 2010. This decrease was primarily attributable to $12.5 million in loans being returned to accrual status during the year ended December 31, 2011. Loans returned to accrual status were current as to principal and interest, and factors indicating doubtful collection no longer existed, including the borrower’s performance under the original loan terms for at least six months. Non-accrual loans also decreased as a result of $4.0 million of pay-offs and principal pay-downs, charge offs of $7.6 million, and the transfer of $2.7 million to other real estate owned. The above decreases in non-accruing loans during the year ended December 31, 2011, were partially offset by $11.3 million of loans being placed on non-accrual status during the year ended December 31, 2011.

Delinquency Status of Total Non-accruing Originated Loans

Generally, loans are placed on non-accrual status when they become 90 days or more delinquent, and remain on non-accrual status until they are brought current, have a minimum of six months of performance under the loan terms, and factors indicating reasonable doubt about the timely collection of payments no longer exist. Therefore, loans may be current in accordance with their loan terms, or may be less than 90 days delinquent, and still be in a non-accruing status.

The following tables detail the delinquency status of originated non-accruing loans (held-for-investment and held-for-sale) at December 31, 2011 and December 31, 2010 (dollars in thousands). All originated delinquent loans in the following two tables are classified as held-for-investment, with the exception of $3.4 million of loans held-for-sale at December 31, 2011. Delinquent loans held-for-sale consisted of $2.3 million in commercial real estate loans, $422,000 in construction and land loans, $473,000 in multifamily loans, and $208,000 in commercial and industrial loans, all of which were 90 days or more delinquent at December 31, 2011, with exception of $633,000 of commercial real estate loans which were 30 to 89 days delinquent.

Originated Loans Subject to Restructuring Agreements

Included in non-accruing loans are loans subject to restructuring agreements totaling $23.3 million and $20.0 million at December 31, 2011, and December 31, 2010, respectively. At December 31, 2011, $19.2 million, or 82.3% of the $23.3 million were performing in accordance with their restructured terms.

The Company also holds loans subject to restructuring agreements, and still accruing, which totaled $18.3 million and $11.2 million at December 31, 2011 and December 31, 2010, respectively. At December 31, 2011, $12.7 million, or 69.0% of the $18.3 million were performing in accordance with their restructured terms. Payments were received subsequent to December 31, 2011, to bring all accruing TDRs current.

The following table details the amounts and categories of the loans subject to restructuring agreements by loan type as of December 31, 2011 and December 31, 2010 (dollars in thousands).

-5-

Originated Loans 90 Days or More Past Due and Still Accruing and Other Real Estate Owned

Loans 90 days or more past due and still accruing decreased $1.5 million to $85,000 at December 31, 2011, as compared to $1.6 million at December 31, 2010. Loans 90 days or more past due and still accruing at December 31, 2011, are considered well-secured and in the process of collection or past maturity, paying interest in accordance with original loan terms, and in the process of renewal.

Other real estate owned amounted to $3.4 million at December 31, 2011 which includes approximately $1.2 million acquired from the FDIC-assisted acquisition, as compared to $171,000 at December 31, 2010.

Delinquency Status of Accruing Originated Loans 30-89 Days Delinquent

Loans 30 to 89 days delinquent and on accrual status at December 31, 2011, totaled $21.1 million, an increase of $1.3 million, from the December 31, 2010 balance of $19.8 million. The following tables set forth delinquencies for accruing loans by type and by amount at December 31, 2011 and December 31, 2010 (dollars in thousands).

Payments were received subsequent to December 31, 2011, on $14.3 million of the loans included in the table above.

-6-

PCI Loans (Held-for-Investment)

PCI loans were recorded at estimated fair value using expected future cash flows deemed to be collectible on the date acquired. Based on its detailed review of PCI loans and experience in loan workouts, management believes it has a reasonable expectation about the amount and timing of future cash flows and accordingly has classified PCI loans ($88.5 million at December 31, 2011) as accruing, even though they may be contractually past due. At December 31, 2011, based on recorded contractual principal, 9.0% of PCI loans were past due 30 to 89 days, and 16.1% were past due 90 days or more, as compared to 8.0% and 13.9% at October 14, 2011.

Results of Operations

Comparison of Operating Results for the Three Months Ended December 31, 2011 and 2010

Net income was $3.8 million for the quarters ended December 31, 2011 and December 31, 2010. Significant variances are as follows: a $1.8 million increase in net interest income, a $3.5 million increase in non-interest income, a decrease of $2.4 million in income tax expense, an increase of $5.5 million in the provision for loan losses, and a $2.3 million increase in non-interest expense.

Net interest income increased $1.8 million, or 11.2%, as interest-earning assets increased by 9.2% to $2.2 billion. The change in the composition of our asset mix towards loans has resulted in a two basis point increase in yields earned on interest earning assets to 4.23% for the current quarter as compared to 4.21% for the prior year comparable period. Yields on loans include $1.4 million in interest income recognized on PCI loans with an average balance of $76.7 million contributing approximately 26 basis points to the net interest margin. Additionally rates paid on interest-bearing liabilities decreased eight basis points to 1.33% for the current quarter as compared to 1.41% for the prior year comparable period. The quarter ended December 31, 2011, included prepayment penalties of $317,000 compared to $45,000 for the quarter ended December 31, 2010. The increase in average interest earning assets was due primarily to increases in average loans outstanding of $240.0 million, $16.2 million in mortgage-backed securities and $17.3 million in interest-earning assets in other financial institutions, partially offset by a decrease in other securities of $89.1 million. Other securities consist primarily of investment-grade shorter-term corporate bonds, and government-sponsored enterprise bonds.

Non-interest income increased $3.5 million or 202.3%, to $5.3 million for the quarter ended December 31, 2011, as compared to $1.8 million for the quarter ended December 31, 2010. This increase was primarily a result a $3.6 million bargain purchase gain, net of tax, associated with the FDIC-assisted acquisition and a $103,000 increase in fees and service charges for customer services, partially offset by decreases income on Bank Owed Life Insurance (BOLI) of $40,000, a decrease in securities transactions, net, of $55,000, and a decrease in other income of $24,000.

Non-interest expense increased $2.3 million, or 22.9%, for the quarter ended December 31, 2011, as compared to the quarter ended December 31, 2010, due primarily to compensation and employee benefits increasing by $1.3 million, or 24.8%, due to increased staff related to branch openings and the FDIC-assisted acquisition, an increase in occupancy expense of $351,000, or 24.4%, primarily due to increases in rent and amortization of leasehold improvements relating to new branches and the renovation of existing branches, an increase in other non-interest expense of $331,000, and a $273,000 increase in professional fees.

-7-

The provision for loan losses was $7.5 million for the quarter ended December 31, 2011; an increase of $5.5 million, or 281.6%, from the $2.0 million provision recorded in the quarter ended December 31, 2010. The increase in the provision for loan losses in the current quarter was due primarily to increased charge-offs primarily due to the transfer of $7.4 million of non performing loans to held-for-sale and increased loan originations. This increase was partially offset by a shift in the composition of our loan portfolio to multi-family loans, which generally require lower general reserves than other commercial real estate loans and decreases in non-performing loans, during the quarter ended December 31, 2011, as compared to the quarter ended December 31, 2010. During the quarter ended December 31, 2011, the Company recorded net charge-offs of $6.1 million (including $4.0 million related to loans transferred to held for sale) compared to net charge-offs of $1.1 million for the quarter ended December 31, 2010.

The Company recorded an income tax benefit of $466,000 for the quarter ended December 31, 2011, compared to an expense of $2.0 million for the quarter ended December 31, 2010. The effective tax rate (benefit rate) for the quarter ended December 31, 2011, was (13.9 %), as compared to 34.0% for the quarter ended December 31, 2010. The decrease in rate was due primarily to the $5.9 million bargain purchase gain recorded in the FDIC-assisted transaction being recorded net of tax, of $2.3 million and lower taxable income.

Comparison of Operating Results for the Year Ended December 31, 2011 and 2010

Net income increased $3.0 million, or 22.0%, to $16.8 million for the year ended December 31, 2011, as compared to $13.8 million for the year ended December 31, 2010, due primarily to an increase of $3.5 million in net interest income and an increase in non-interest income of $5.0 million, partially offset by a $2.5 million increase in the provision for loan losses, an increase of $2.8 million in non-interest expense and an increase of $127,000 in income tax expense.

Net interest income increased $3.5 million, or 5.7%, as interest-earning assets increased by 8.8% to $2.2 billion. The general decline in interest rates has resulted in yields earned on interest earning assets to decline 14 basis points to 4.17% for the current year as compared to 4.31% for the prior year, while rates paid on interest-bearing liabilities decreased 11 basis points to 1.42% for the current year as compared to 1.53% for the prior year comparable period. Yields on loans include $1.4 million in interest income recognized on PCI loans with an average balance of $19.3 million contributing approximately seven basis points to the net interest margin. Additionally, the year ended December 31, 2011, included prepayment penalties of $812,000 compared to $67,000 for the year ended December 31, 2010. The increase in average interest earning assets was due primarily to increases in average loans outstanding of $153.5 million and $124.3 million in mortgage-backed securities, partially offset by a decrease in other securities. Other securities consist primarily of investment-grade shorter-term corporate bonds and government-sponsored enterprise bonds.

Non-interest income increased $5.0 million, or 73.0%, to $11.8 million for the year ended December 31, 2011, as compared to $6.8 million for the year ended December 31, 2010. This increase was primarily a result of a $3.6 million bargain purchase gain, net of taxes, associated with the FDIC-assisted acquisition in October 2011, a $750,000 increase in gains on security sales, a $364,000 increases in fees and service charges for customer services, and a $694,000 increase in income earned on bank owned life insurance, generated by increased cash surrender values, primarily resulting from higher levels of bank owned life insurance. The Company routinely sells securities when market pricing presents, in management’s assessment, an economic benefit that outweighs holding such securities, and when smaller balance securities become cost prohibitive to carry. These increases were partially offset by an increase of $255,000 in other-than-temporary credit impairment charges recognized on two private label mortgage backed securities and an equity mutual fund and a decrease of $120,000 in other income.

Non-interest expense increased $2.8 million, or 7.4%, for the year ended December 31, 2011, as compared to the year ended December 31, 2010, due primarily to compensation and employee benefits expense increasing $2.6 million, which resulted primarily from increases in employees related to additional branch and operations personnel, and to a lesser extent, salary adjustments effective January 1, 2011. Occupancy expense increased $1.1 million, or 22.3%, over the same time period, primarily due to increases in rent and amortization of leasehold improvements relating to new branches and the renovation of existing branches. These increases were partially offset by decreased professional fees of $1.3 million, primarily resulting from the expensing of approximately $1.8 million in costs incurred for the Company’s postponed, second-step stock offering in the prior year partially offset by increased costs related to loan workouts.

The provision for loan losses was $12.6 million for the year ended December 31, 2011; an increase of $2.5 million, or 24.8%, from the $10.1 million provision recorded in the year ended December 31, 2010. The increase in the provision for loan losses in the current year was due primarily to increased charge-offs and increased loan originations partially offset by a shift in the composition of our loan portfolio to multi-family loans, which generally require lower general reserves than other commercial real estate loans and decreases in non-performing loans, during the year ended December 31, 2011, as compared to the year ended December 31, 2010. During the year ended December 31, 2011, the Company recorded net charge-offs of $7.6 million compared to net charge-offs of $3.7 million for the year ended December 31, 2010. Including $4.0 related to the transfer of $7.4 million of loans to held-for-sale.

The Company recorded income tax expense of $6.5 million and $6.4 million for the years ended December 31, 2011, and 2010, respectively. The effective tax rate for the year ended December 31, 2011, was 27.8%, as compared to 31.6% for the year ended December 31, 2010. The decrease in rate was due primarily to the $5.9 million bargain purchase gain recorded in the FDIC-assisted transaction being recorded net of tax, of $2.3 million and lower taxable income in the current year as a result of in an increase in tax exempt bank owned life insurance income of $694,000.
