FOR IMMEDIATE RELEASE

Hill International Reports First Quarter 2014 Financial Results

Marlton, NJ — May 8, 2014 — Hill International (NYSE:HIL), the global leader in managing construction risk, announced today financial results for the first quarter ended March 31, 2014 (see attached tables).

Total revenue for the first quarter of 2014 was a record $150.0 million, an increase of 10.2% from the first quarter of 2013.  Consulting fee revenue for the first quarter of 2014 was a record $137.2 million, an increase of 12.0% from last year’s first quarter.

EBITDA (as defined below) for the first quarter of 2014 was $8.2 million, a 14.0% decrease from the first quarter of 2013.  Operating profit for the first quarter was $6.0 million, an 18.9% decline from last year’s first quarter.  Net earnings for the first quarter were $0.1 million, or $0.00 per diluted share, compared to a net loss of ($0.4 million) in the first quarter of 2013, or ($0.01) per diluted share.

The company’s total backlog at March 31, 2014 was $978 million compared to $1.027 billion at December 31, 2013.  Twelve-month backlog at March 31, 2014 was a record $400 million compared to $394 million at December 31, 2013.

“Our strong growth has continued into 2014, with Hill having achieved record consulting fees in the first quarter,” said Irvin E. Richter, Hill’s Chairman and Chief Executive Officer. “Our top priority, however, continues to be the lowering of our interest expense so that more of our operating profit can drop to the bottom line, and we expect significant progress on this effort in the near future,” added Richter.

2014 Guidance

Based upon current market conditions and the backlog described above, the company reaffirms its prior estimate that consulting fee revenue for 2014 will be between $575 million and $600 million.  This guidance reflects approximately 12% to 17% growth in consulting fee revenue for the year.

EBITDA Reconciliation

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) for the first quarter of 2014 were $8.2 million compared to $9.5 million in the first quarter of 2013.  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, capital expenditures and debt service.  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:
