1. Basis of Presentation

The consolidated financial statements of Answerthink,Inc. (“Answerthink” or the “Company”) include the accounts of the Company and all of its wholly owned subsidiaries. All material intercompany transactions and balances have been eliminated in consolidation.

In the opinion of management, the accompanying consolidated financial statements reflect all normal and recurring adjustments which are necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows as of the dates and for the periods presented. The consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Accordingly, these statements do not include all the disclosures normally required by accounting principles generally accepted in the United States of America for annual financial statements and should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 30, 2005 included in the Form 10-K filed by the Company with the Securities and Exchange Commission. The consolidated results of operations for the quarter and six months ended March 31,June 30, 2006 are not necessarily indicative of the results to be expected for any future period or for the full fiscal year.

2. Net LossIncome (Loss) Per Common Share

Basic net lossincome (loss) per common share is computed by dividing net lossincome (loss) by the weighted average number of common shares outstanding during the period. With regard to common stock subject to vesting requirements or restricted stock units issued to employees, the calculation includes only the vested portion of such stock. Accordingly, common shares outstanding for the basic net lossincome (loss) per share computation is lower than actual shares issued.

Net lossincome (loss) per common share assuming dilution is computed by dividing net lossincome (loss) by the weighted average number of common shares outstanding, increased by the assumed conversion of other potentially dilutive securities during the period. For the quarters ended June 30, 2006 and July 1, 2005 potentially dilutive securities included 1,711,979 and 2,143,439 of unvested restricted stock units issued to employees and 256,095 and 176,092 of common stock issuable upon the exercise of stock options following the treasury stock method.

Approximately 1.5 million and 2.0 million stock options were excluded from the computations of diluted net income per common share for the quarters ended June 30, 2006 and July 1, 2005 as their stock price was higher than the Company’s average stock price.

Potentially dilutive shares were excluded from the diluted loss per share calculation for the quarterssix months ended March 31,June 30, 2006 and AprilJuly 1, 2005 because their effects would have been anti-dilutive to the loss incurred by the Company. Therefore, the amounts reported for basic and diluted net loss per share were the same for those periods. Potentially dilutive securities which were not included in the diluted loss per share calculation for the quarterssix months ended March 31,June 30, 2006 and AprilJuly 1, 2005 include 1,705,2121,708,596 and 2,181,5912,162,515 shares respectively, of unvested common stock subject to vesting requirements and restricted stock units issued to employees and 327,407291,751 and 293,691234,892 shares respectively, of common stock issuable upon the exercise of stock options following the treasury stock method.

5. Loan Payable

At December 30, 2005, the Company had a loan with a financial institution of $3.7 million, classified as loan payable in the accompanying balance sheet. The loan was secured by $3.7 million of cash, classified as current restricted cash in the accompanying balance sheet as of December 30, 2005. This bank loan carried interest on the balance, net of restricted cash, of 2% over National Westminster Bank’s base rate, which was 4.5% at December 30, 2005. During March 2006, the Company used the restricted cash amount to repay the loan.

6. Restructuring Accrual

The Company recorded restructuring costs of $10.9 million and $5.6 million in fiscal years 2002 and 2001, respectively, for reductions in associates and functional support personnel and for closure and consolidation of facilities and related exit costs. These actions were taken as a result of the decline in demand for technology services throughout 2001 and 2002. The Company took steps to reduce its costs to better align its overall cost structure and organization with anticipated demand for services.

In 2004 and 2003, the Company recorded restructuring costs of $3.7 million and $4.9 million, respectively, to increase existing reserves to account for potentially higher estimated losses on the sublease of facilities as a result of lower than expected sublease rates and longer than expected time estimates to sublease excess facilities. The 2004 and 2003 restructuring costs consisted of additions of $1.8 million and $3.1 million to the 2002 restructuring accrual and $1.9 million and $1.8 million to the 2001 restructuring accrual, respectively. Also in 2004, the 2002 restructuring accrual was reduced by $370 thousand relating to the final settlement of a lease obligation which was recorded as income from discontinued operations in the consolidated statement of operations for the year ended December 31, 2004.

InDuring the first and fourth quarters of 2005, the Company recorded restructuring costs of $2.9 million which related to $1.1 million for the consolidation of additional facilities and related exit costs not included in previously established reserves primarily as a result of the REL Consultancy Group acquisition on November 29, 2005 and $1.8 million for increases in previously established reserves in 2002 and 2001 for the closure and consolidation of facilities, of which $1.1 million is specifically related to the increase of previously established reserves in order to reflect the negotiated buyout of our New York City lease obligation. As a result of the buyout, the Company was fully released from $20 million of future lease obligations, assigned two subleases to the lessor, wrote-off $1.4 million receivable from the lessor, and paid $3.1 million in cash to the lessor. The remaining $700 thousand related to increases in the reserves to account for higher estimated losses on the sublease of facilities as a result of lower than expected sublease rates and longer than expected time estimates to sublease facilities based on current market conditions. The 2005 restructuring costs of $1.8 million related to previously established reserves consisted of additions of $1.2 million and $600 thousand to the 2002 and 2001 restructuring accruals, respectively.

6. Restructuring Accrual (continued)

InDuring the first quarter of 2006, the Company recorded restructuring costs of $6.3 million, which was comprised of $2.8 million relating to the 2005 restructuring for the consolidation of additional facilities and related exit costs primarily as a result of the REL Consultancy Group acquisition and $3.5 million for increases in previously established reserves in 2002 and 2001 for the closure and consolidation of facilities to account for higher estimated losses on the sublease of facilities as a result of lower than expected sublease rates and longer than expected time estimates to sublease facilities based on current market conditions. Included in the $2.8 million is a further reduction of occupied space in our technology focused facility in Philadelphia and related severance costs for a senior executive as the Company’s primary business model shifts to a proprietary best practice and intellectual capital and strategic advisory services firm.

The following table sets forth the detail and activity in the restructuring expense accrual during the quartersix months ended March 31,June 30, 2006 (in thousands):

7. Stock Based Compensation

In December 2004, the Financial Accounting Standards Board issued SFAS No. 123R,Share-Based Payment(“SFAS No. 123R”). This Statement is a revision of SFAS No. 123,Accounting for Stock-Based Compensation(“SFAS No. 123”), and supersedes Accounting Principles Board Opinion No. 25,Accounting for Stock Issued to Employees(“APB No. 25”), and its related implementation guidance. On December 31, 2005, the Company adopted the provisions of SFAS No. 123R using the modified prospective method. SFAS No.123R focuses primarily on accounting for transactions in which an entity obtains employee services in share-based payment transactions. The Statement

Answerthink, Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(unaudited)

7. Stock Based Compensation (continued)

requires entities to recognize compensation expense for awards of equity instruments to employees based on the grant-date fair value of those awards (with limited exceptions). SFAS No. 123R also requires the benefits of tax deductions in excess of recognized compensation expense to be reported as a financing cash flow, rather than as an operating cash flow as prescribed under the prior accounting rules. This requirement reduces net operating cash flows and increases net financing cash flows in periods after adoption. Total cash flow remains unchanged from what would have been reported under prior accounting rules. Upon the adoption of SFAS No. 123R, the Company recognized an immaterial one-time gain based on SFAS No. 123R’s requirement to apply an estimated forfeiture rate to unvested restricted stock and restricted stock unit awards. Previously, the Company recorded forfeitures as incurred for such awards.

Prior to the adoption of SFAS No. 123R, the companyCompany followed the intrinsic value method in accordance with APB No. 25 to account for its employee stock plans. Accordingly, no compensation expense was recognized for the issuance of stock options or shares granted through the Employee Share Purchase Plan (the “ESPP”); however, compensation expense was recognized in connection with the issuance of restricted stock units and common stock subject to vesting requirements. The adoption of SFAS No. 123R primarily resulted in the Company estimating forfeitures for all unvested common stock subject to vesting requirements and restricted stock unit awards and the recognition of compensation expense for the unvested portion of previously granted stock options.

The following table shows the effect of adopting SFAS No. 123R on selected reported items (“As Reported”) and what those items would have been under previous guidance under APB No. 25:

Results for the quarter and six months ended AprilJuly 1, 2005 have not been restated. Had compensation expense for employee stock options granted under the Company’s stock plans been determined based on fair value at the grant date consistent with SFAS No. 123, the Company’s net lossincome (loss) and net lossincome (loss) per share for the threequarter and six months ended AprilJuly 1, 2005 would have been adjusted to the pro forma amounts indicated below:

Other information pertaining to option activity during the quarter was as follows (in thousands):

The Company recorded stockstock- based compensation totaling $162$120 thousand and $282 thousand during the quarter and six months ended March 31,June 30, 2006, respectively, related to the unvested portion of previously granted stock options. The Company granted 45,000 options during the quarter and six months ended July 1, 2005.

SFAS No. 123R requires the use of a valuation model to calculate the fair value of stock option awards. The Company has elected to use the Black-Scholes option-pricing model, which incorporates various assumptions including volatility, expected life, and interest rates. The expected volatility is based on the historical volatility of the Company’s common stock over the most recent period commensurate with the estimated expected life of the Company’s stock options. The expected life of an award is based on historical experience and on the terms and conditions of the stock awards granted to employees. The following assumptions were used by the Company to determine the fair value of stock options granted during 2005 using the Black-Scholes options-pricing model:

Restricted Stock Units

Under the stock plans, participants may be granted restricted stock units, each of which represents a conditional right to receive a common share in the future. The restricted stock units granted under this plan generally vest over a four-year period, with 50% vesting on the second anniversary and 25% of the shares vesting on the third and fourth anniversaries of the grant date. Upon vesting, the restricted stock units will convert into an equivalent number of shares of common stock. The amount of expense relating to the restricted stock units is based on the closing market price of the Company’s common stock on the date of grant and is amortized on a straight-line basis over the four-year requisite service period. Restricted stock unit activity for the quartersix months ended March 31,June 30, 2006 was as follows:

The Company recorded stock based compensation totaling $745$1,489 thousand and $605$1,325 thousand, respectively, related to restricted stock units during the quarterssix months ended March 31,June 30, 2006 and AprilJuly 1, 2005.

8. Shareholders’ Equity

Employee Stock Purchase Plan

Effective July 1, 1998, the Company adopted an Employee Stock Purchase Plan to provide substantially all employees who have completed three months of service as of the beginning of an offering period an opportunity to purchase shares of its common stock

through payroll deductions. Purchases on any one grant are limited to 10% of eligible compensation. Participant account balances are used to purchase shares of stock at the lesser of 85% of the fair market value of shares on the first trading day of the six-month offering period or on the last trading day of such offering period. The aggregate fair market value, determined as of the first trading date of the offering period, as to shares purchased by an employee may not exceed $25,000 annually. During the fourth quarter of fiscal 2005, the Board of Directors approved a change to the common stock purchase discount and approved the elimination of the related look back period. As a result, effective beginning in fiscal 2006, shares of our common stock may be purchased by employees at six month intervals at 95% of the fair market value on the last trading day of each six month period. The plan, as amended, is considered non-compensatory, and as such, no stock based compensation was recorded in connection with the plan during the quartersix months ended March 31,June 30, 2006. The Employee Stock Purchase Plan expires on July 1, 2008. A total of 4,275,000 shares of common stock are available for purchase under the plan with a limit of 400,000 shares of common stock to be issued per offering period.

In 2003, 2004 and 2005, the Board of Directors approved the repurchase of an additional $25 million of the Company’s common stock, thereby increasing the total program size to $30 million. Under the repurchase plans, the Company may buy back shares of its outstanding stock from time to time either on the open market or through privately negotiated transactions, subject to market conditions and trading restrictions.

11. Recent Accounting Pronouncements

In July 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109 (FIN 48), which clarifies the accounting for uncertainty in tax positions. This Interpretation requires that the Company recognize in its financial statements, the impact of a tax position, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. The provisions of FIN 48 are effective as of the beginning of the Company’s 2007 fiscal year, with the cumulative effect of the change in accounting principle recorded as an adjustment to opening retained earnings. The Company is currently evaluating the impact of adopting FIN 48 on its financial statements.

Results of Operations

The following table sets forth, for the periods indicated, our results of operations and the percentage relationship to revenues of such results:

Revenues.Revenues for the quarter ended March 31,June 30, 2006 increased by $13.0$7.3 million or 35%17% to $49.8$49.0 million from $36.9$41.7 million in the quarter ended AprilJuly 1, 2005. Revenues for the six months ended June 30, 2006 increased $20.3 million or 26% to $98.8 million from $78.6 million in the six months ended July 1, 2005. The increase in revenues for the quarter and six months ended March 31,June 30, 2006 was primarily attributable to revenue of approximately $6.2$6.3 million and $12.5 million, respectively, relating to REL Consultancy Group Limited (“REL”) which was acquired on November 29, 2005, increased revenue from our membership advisory program sales and related transformation advisory services and increased revenue from our Hyperion implementation practice. Reimbursements as a percentage of revenues during the quarters and six months ended March 31,June 30, 2006 and AprilJuly 1, 2005 were comparable at 10%. During the quartersquarter and six months ended March 31,June 30, 2006, no customer accounted for revenues equal to or greater than 5% of total revenues. During the quarter and Aprilsix months ended July 1, 2005, one customer and two customers, accounted forrespectively, had revenues equal to or greater than 5% of total revenues, which together accountedaccounting for 5% and 11% and 13% of total revenues, respectively. With respect to our two largest customers in 2006, ourOur contracts can be cancelled for convenience by the customer upon 30 days’ notice. Our projects with these customers expire on various dates ranging from April 2006 to September 2006. During the quarter ended March 31, 2006, one of these customersa significant customer filed for bankruptcy protection. In order to mitigate our credit risk, we entered into an agreementagreements with a third party on April 19, 2006 and on June 29, 2006 to sell our pre-bankruptcy accounts receivable from this customer for 65% and 75% of the total outstanding balance.balances, respectively. The remaining 35%amounts due under the terms of the balance has been fully reserved for at March 31,these agreements were collected in full subsequent to June 30, 2006. We do not anticipate any credit and/or collection issues with the other significant customer. The cancellation or significant reduction in the use of services from these key customers could have a material adverse effect on our results of operations. As is customary with most of our significant relationships, we may be able to continue with new and follow-on projects as these initiatives progress into subsequent phases. However, there is no assurance that we will be able to renew these contracts. The cancellation or significant reduction in the use of services from these key customers could have a material adverse effect on our results of operations.

Cost of Service.Cost of service primarily consistconsists of salaries, benefits and incentive compensation for consultants and reimbursable expenses associated with projects. Cost of service was $31.4$29.6 million in the quarter ended March 31,June 30, 2006 an increase of $7.2$5.0 million or 30%20% compared to the quarter ended AprilJuly 1, 2005. Cost of service was $61.0 million in the six months ended June 30, 2006, an increase of $12.2 million or 25% compared to the six months ended

July 1, 2005. This increase was primarily attributable to the increase in total billable headcount as a result of the REL acquisition in November 2005. Consultant average headcount for the six months ended June 30, 2006 was 670 as of March 31, 2006656 compared to 569 asconsultant average headcount of April573 for the six months ended July 1, 2005.

The Hackett Group annualized revenue per professional was $387 thousand for the quarter ended June 30, 2006, as compared to $403 thousand in the quarter ended July 1, 2005. The decrease in The Hackett Group revenue per professional was primarily attributable to lower than expected revenue in our Transformation Advisory practice. Cost of service as a percentage of revenue for the six months ended June 30, 2006 and July 1, 2005 was comparable at $350 thousand in 2006 and $352 thousand in 2005.62%.

Selling, General and Administrative.Selling, general and administrative expenses increased 34%6% to $17.8$17.1 million in the quarter ended March 31,June 30, 2006 from $13.3$16.1 million in the quarter ended AprilJuly 1, 2005. Selling, general and administrative expenses increased 18% to $34.9 million in the six months ended June 30, 2006 from $29.4 million in the six months ended July 1, 2005.

Selling, general and administrative expenses as a percentage of revenues were comparable at 36%35% and 39% and 35% and 37%, respectively, during the quarters and six months ended March 31,June 30, 2006 and AprilJuly 1, 2005. The overall decreases are primarily attributable to benefits achieved from the company’s restructuring efforts to rationalize real estate investments and benefits achieved from the integration of REL’s back office functions.

Restructuring Costs.We did not record any restructuring costs for the quarters ended June 30, 2006 and July 1, 2005. However, we recorded restructuring costs of $6.3 million in the quarter ended March 31, 2006 which was comprised of $2.8 million relating to the 2005 restructuring for the consolidation of additional facilities and related exit costs primarily as a result of the REL Consultancy Group acquisition and $3.5 million for increases in previously established reserves in 2002 and 2001 for the closure and consolidation of facilities to account for higher estimated losses on the sublease of facilities as a result of lower than expected sublease rates and longer than expected time estimates to sublease facilities based on current market conditions. Included in the $2.8 million is a further reduction of occupied space in our technology focused facility in Philadelphia and related severance costs for a senior executive as the Company’s primary business model shifts to a proprietary best practice intellectual capital and strategic advisory services firm. WeAdditionally, we recorded restructuring costs of $1.1 million in the quarter ended April 1, 2005 to increase previously established reserves in order to reflect the negotiated buyout of our New York City lease obligation.

Income Taxes.We recorded income taxes of $365$697 thousand for the quartersix months ended March 31,June 30, 2006.

This amount reflects an estimated annual 7% tax rate for 2005 for$19 thousand, primarily attributable to certain state and foreign taxes. The liability method of accounting for deferred income taxes requires that a change in the valuation allowance for deferred tax assets be included in income tax expense or benefit for the current period.

Liquidity and Capital Resources

We may decide to raise additional funds in order to fund expansion, to develop new or enhanced products and services, to respond to competitive pressures or to acquire complementary businesses or technologies. There is no assurance, however, that additional financing will be available when needed or desired.

Recent Accounting Pronouncements

In July 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109 (FIN 48), which clarifies the accounting for uncertainty in tax positions. This Interpretation requires that we recognize in our financial statements, the impact of a tax position, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. The provisions of FIN 48 are effective as of the beginning of our 2007 fiscal year, with the cumulative effect of the change in accounting principle recorded as an adjustment to opening retained earnings. We are currently evaluating the impact of adopting FIN 48 on our financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

At March 31,June 30, 2006, our exposure to market risk related primarily to changes in interest rates on our investment portfolio. Our marketable investments consist primarily of short-term fixed interest rate securities. We invest only with high credit quality issuers and we do not use derivative financial instruments in our investment portfolio. We do not believe that a significant increase or decrease in interest rates would have a material impact on the fair value of our investment portfolio.

Exchange Rate Sensitivity

We face exposure to adverse movements in foreign currency exchange rates, as a portion of our revenues, expenses, assets and liabilities are denominated in currencies other than the U.S. Dollar, primarily the British pound and the euro. These exposures may change over time as business practices evolve. Currently, we do not hold any derivatives contracts that hedge our foreign currency risk, but we may adopt such strategies in the future.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of our disclosure controls and procedures (“Disclosure Controls”) pursuant to Rule 13a-14(c) and Rule 15d-14(c) under the Securities Exchange Act of 1934. Based upon that evaluation, the CEO and CFO concluded that our Disclosure Controls are effective in timely alerting them to material information required to be included in our periodic SEC filings. On November 29, 2005, our Hackett Group Limited (UK) subsidiary acquired REL Consultancy Group Limited (UK) or REL. Our management has not yet completed an evaluation of the effectiveness of internal control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission for the acquired subsidiary as it was not considered material to the results of our operations, financial position and cash flows from the date of acquisition through December 30, 2005. We intend to disclose all material changes to internal control over financial reporting resulting from the acquisition, if any, within the time period for our first annual assessment of the internal control over financial reporting that is required of this entity.

Limitations on the Effectiveness of Controls

Our management, including our CEO and CFO, does not expect that our Disclosure Controls and internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the companyCompany have been detected. These inherent limitations include the realities that judgementsjudgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control.

Changes in Internal Controls

With the exception of the implementation of internal controls relating to REL,there were no changes in our internal control over financial reporting that occurred during the period covered by this Quarterly report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. The Company’s disclosure controls and procedures have been updated to ensure that the financial information of REL has been properly recorded.
