“We are extremely pleased with our excellent financial performance in the fourth quarter and for the entire year of 2007, having achieved record revenue, record profits and record backlog,” said Irvin E. Richter, Hill’s Chairman and Chief Executive Officer. “We intend to build on this success in 2008 and beyond through continued strong organic growth, particularly overseas, and through strategic acquisitions,” Richter added.

Fourth Quarter 2007 Results

Total revenue for the fourth quarter of 2007 increased 28.2% to $86.3 million from $67.3 million for the fourth quarter of 2006. Consulting fee revenue for the fourth quarter of 2007 increased 37.7% to $58.7 million from $42.6 million for the prior year quarter. During the fourth quarter of 2007, the growth in Hill’s consulting fee revenue was comprised of 28.1% organic growth and 9.6% acquisition growth.

Consulting fee revenue at Hill’s Project Management Group for the fourth quarter of 2007 increased 50.6% to $40.0 million from $26.5 million for the year earlier quarter. That percentage growth was comprised of 35.2% organic growth, primarily from the Middle East/North Africa region, and 15.4% growth from the acquisition of KJM & Associates, Ltd. (“KJM”) in May 2007.

Consulting fee revenue at Hill’s Construction Claims Group for the fourth quarter of 2007 rose 16.4% to $18.7 million from $16.1 million for the fourth quarter of 2006, entirely the result of organic growth worldwide.

Gross profit increased 39.8% to $28.2 million in the fourth quarter of 2007 from $20.2 million in the fourth quarter of 2006. Gross profit margin as a percentage of consulting fee revenue increased to 48.1% in the fourth quarter of 2007 from 47.4% in the same period last year due to a higher proportion of fourth quarter revenue from the Construction Claims Group, which has a higher gross profit margin than the Project Management Group.

Selling, general and administrative (“SG&A”) expenses grew 38.5% to $24.0 million in the fourth quarter of 2007 from $17.4 million in the same period of 2006. This increase was due primarily to the addition of SG&A expenses of KJM, amortization costs associated with the Knowles and KJM acquisitions and a continued build-up of corporate headquarters staff in connection with Hill’s recent and anticipated growth and as a result of Hill becoming a publicly-traded company in June 2006. SG&A as a percentage of consulting fee revenue was 40.9% during the fourth quarter of 2007, up slightly from 40.7% during the same period in 2006.

Operating profit in the fourth quarter of 2007 improved by 47.3% to $5.0 million (or 8.5% of consulting fee revenue) from $3.4 million (or 8.0% of consulting fee revenue) in the comparable prior-year period.

Income taxes decreased $0.7 million, or 83.8%, from $0.8 million in the fourth quarter 2006 to $0.1 million in the fourth quarter of 2007 even though taxable income increased $1.7 million, or 49.3%, from $3.4 million in the fourth quarter of 2006 to $5.2 million in the fourth quarter of 2007. We continue to realize a large portion of our pre-tax income from foreign jurisdictions which impose lower income tax rates, if any. We also realized a significant tax credit resulting from the reversal of a prior year’s uncertain tax position amounting to $0.6 million.

Net earnings in the fourth quarter of 2007 jumped by 88.8% to $5.1 million (or $0.14 per diluted common share based on approximately 35.9 million diluted common shares outstanding) from $2.7 million (or $0.11 per diluted common shared based on approximately 25.2 million diluted common shares outstanding) in the fourth quarter of 2006. The diluted earnings per share for 2007 were unfavorably impacted by a significant increase in diluted shares outstanding as a result of (i) warrants and options becoming more dilutive due to a significant increase in the market price of the Company’s common stock in late 2007 and (ii) the exercise of substantially all of the Company’s warrants in late 2007. The total cash proceeds generated from the exercise of the warrants was approximately $67.9 million most of which was received during the fourth quarter of 2007.

EBITDA (earnings before interest, taxes, depreciation and amortization) for the fourth quarter of 2007 grew to $5.8 million, an increase of 28.5% from the fourth quarter of 2006. EBITDA is not a measure of financial performance under generally accepted accounting principles (“GAAP”). Management believes EBITDA, in addition to operating profit, net income and other GAAP measures, is a useful indicator of Hill’s financial and operating performance and its ability to generate cash flows from operations that are available for taxes and capital expenditures. Investors should recognize that EBITDA might not be comparable to similarly-titled measures of other companies. This measure should be considered in addition to, and not as a substitute for or superior to, any measure of performance prepared in accordance with GAAP. Reconciliations of EBITDA amounts to the most directly comparable GAAP measures for the three-month periods ended December 31, 2007 and December 30, 2006 are included in the financial information provided as part of this release.

Total backlog at December 31, 2007 was a record $416 million, up from $380 million at September 30, 2007 and from $247 million at the end of 2006. Twelve-month backlog at December 31, 2007 was a record $196 million, up from $179 million at September 30, 2007 and from $129 million at the end of 2006.

Hill’s balance sheet at December 31, 2007 reflected cash and cash equivalents of $66.1 million, working capital of $102.8 million, total debt of $3.3 million and stockholders’ equity of $128.4 million.

Full Year 2007 Results

Total revenue for the year ended December 31, 2007 increased 48.7% to $290.3 million from $197.5 million for the fiscal year ended December 30, 2006. Consulting fee revenue for 2007 increased 56.3% to $203.1 million from $130.0 million for 2006. During 2007, Hill’s consulting fee revenue growth was comprised of 30.6% organic growth primarily from the Middle East/North Africa region and 25.7% growth from acquisitions.

Consulting fee revenue at Hill’s Project Management Group for 2007 increased 39.6% to $135.0 million from $96.7 million for 2006. That percentage growth was comprised of 29.1% organic growth and 10.5% growth from the acquisition of KJM.

Consulting fee revenue at Hill’s Construction Claims Group for 2007 rose 104.6% to $68.2 million from $33.3 million for 2006. That percentage growth was comprised of 35.4% organic growth and 69.2% growth from the acquisition of James R. Knowles (Holdings) PLC (“Knowles”) in September 2006.

Gross profit increased 63.3% to $96.3 million in 2007 from $59.0 million in 2006. Gross profit margin as a percentage of consulting fee revenue increased to 47.4% in 2007 from 45.4% in 2006 due to a higher proportion of revenue from the Construction Claims Group (as a result of the Knowles acquisition) which has a higher gross profit margin than the Project Management Group.

SG&A expenses grew 66.2% to $80.9 million in 2007 from $48.7 million in 2006. This increase was due primarily to the inclusion of SG&A expenses of Knowles and KJM, amortization costs associated with the Knowles and KJM acquisitions and significantly higher corporate overhead costs as a result of Hill’s recent and anticipated growth and as a result of Hill becoming a publicly-traded company in June 2006. SG&A as a percentage of consulting fee revenue in 2007 was 39.8% as compared to 37.4% in 2006.

Operating profit in 2007 improved by 54.9% to $17.6 million (or 8.7% of consulting fee revenue) from $11.4 million (or 8.7% of consulting fee revenue) in 2006.

Income taxes increased $0.3 million, or 10%, from $2.5 million in 2006 to $2.8 million in 2007 as taxable income increased $5.8 million, or 53%, from $11.1 million in 2006 to $16.9 million in 2007. We continue to realize a large portion of our pre-tax income from foreign jurisdictions which impose lower income tax rates, if any. We also realized a significant tax credit resulting from the reversal of a prior year’s uncertain tax position amounting to $0.6 million.

Net earnings in 2007 increased 64.8% to $14.1 million (or $0.45 per diluted common share based on approximately 31.4 million diluted common shares outstanding) from $8.6 million (or $0.46 per diluted common shared based on approximately 18.5 million diluted common shares outstanding) in 2006. The increase in shares outstanding for 2007 was primarily due to the November 2007 warrant redemption.

EBITDA for 2007 grew to $21.1 million, an increase of 57.3%, from $13.4 million in 2006. Reconciliations of EBITDA amounts to the most directly comparable GAAP measures for years ended December 31, 2007 and December 30, 2006 are included in the financial information provided as part of this release.

Achievement of 2007 Earnout

The Agreement and Plan of Merger, dated December 5, 2005, as amended, between Hill and Arpeggio Acquisition Corporation, provides for certain stockholders of Hill to receive up to an additional 6,600,000 shares of the combined company’s common stock, contingent upon the combined company attaining certain targets for earnings before interest and taxes (“EBIT”) over a four-year period. Hill’s EBIT for the fiscal year ended December 31, 2007 was $17.4 million and the target for the earnout for that year was $13.5 million. Therefore, the contingent shares for 2007 have been earned and an additional 2,300,000 shares of Hill’s common stock are expected to be issued during the second quarter of 2008.

Recent Acquisitions

On February 15, 2008, Hill acquired a 60% interest in Gerens Management Group, S.A., a leading Spanish-headquartered firm that provides project management services on major construction projects throughout Spain as well as in Western Europe and Latin America. The acquisition provided Hill with entry into important new geographic markets. The consideration paid by Hill amounted to €10.8 million ($15.8 million) in cash. In 2007, Gerens had unaudited total revenues of approximately €21.0 million ($30.6 million). At December 31, 2007, Gerens had total backlog of €27.3 million ($39.9 million).

On January 4, 2008, Hill acquired John Shreeves Holdings Ltd. and its operating subsidiary John Shreeves & Partners Ltd. (collectively “Shreeves”), a London-based firm that provides project management and cost consultancy services on private- and public-sector projects throughout the United Kingdom. Shreeves’ clients include some of the largest tenants, developers and public entities in the United Kingdom. For its last fiscal year, ended April 30, 2007, Shreeves had revenues of approximately £2.4 million ($4.9 million).
