FOR IMMEDIATE RELEASE

Hill International Reports Second Quarter 2009 Financial Results;

Consulting Fees Up 11.9% and Net Earnings Up 24.3%

Marlton, NJ – August 4, 2009 – Hill International (NYSE: HIL), the global leader in managing construction risk, announced today financial results for the second quarter ended June 30, 2009 and for the first six months of 2009 (see attached tables). Total revenue for the second quarter of 2009 grew to $104.3 million, an increase of 7.7% from the second quarter of 2008. Consulting fee revenue for the second quarter of 2009 grew to $91.5 million, an increase of 11.9% from the second quarter of 2008. That percentage growth was comprised of 9.3% organic growth and 2.6% growth from acquisitions.

Operating profit for the second quarter of 2009 improved to $6.5 million, an increase of 14.8% from the second quarter of 2008. Net earnings in the second quarter of 2009 grew to $4.7 million (or $0.12 per diluted share based on 40.3 million diluted shares), up 24.3% from the second quarter of 2008.

Total backlog at the end of the second quarter of 2009 increased to $611 million from $598 million at March 31, 2009. Twelve-month backlog at the end of the second quarter of 2009 grew to $279 million from $270 million at March 31, 2009.

“Hill’s financial performance during the second quarter was strong, especially given the ongoing economic recession in which we are operating,” said Irvin E. Richter, Hill’s Chairman and Chief Executive Officer. “In addition, there are signs that our markets are beginning to recover, and we have positive expectations for the second half of the year and heading into 2010,” added Richter.

First Half 2009 Results

Total revenue for the first six months of 2009 rose to $208.3 million, an increase of 17.2% from the first six months of 2008. Consulting fee revenue for the first six months of 2009 grew to $183.7 million, an increase of 21.3% from the first six months of 2008. That percentage growth was comprised of 15.4% organic growth and 5.9% growth from acquisitions.

Operating profit for the first six months of 2009 declined to $10.8 million, a decrease of 3.1% from the first six months of 2008, principally due to previously disclosed first quarter 2009 items such as currency devaluations, an increase in bad debt expense and costs incurred in connection with a discontinued acquisition. Net earnings for

the first six months declined to $9.1 million (or $0.22 per diluted share based on 40.7 million diluted shares), down 14.3% from the first six months of 2008.

EBITDA Reconciliation

(Unaudited)

EBITDA (earnings before interest, taxes, depreciation and amortization) for the second quarter of 2009 rose to $7.9 million, an increase of 17.3% from the first quarter of 2008. 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. A reconciliation of EBITDA to the most directly comparable GAAP measure in accordance with SEC Regulation S-K follows:
