October 23, 2002
Schedules 3Q02 Earnings Conference Call For Oct. 31st

HOUSTON, October 23, 2002 – Hanover Compressor Company (NYSE: HC), the leading provider of outsourced natural gas compression services, today announced it has completed its review of prior business transactions and, with the concurrence of its independent auditors, will restate 1999 financial results to more properly reflect four transactions totaling revenues of $5.1 million and net income of $2.0 million.

The decision follows completion of reviews by management, the board of directors, and outside counsel of 1999 transactions.

“Senior management is satisfied it has conducted a thorough review of prior transactions and, consequently, will certify and file with the Securities and Exchange Commission within 30 days amended financial results for 1999, 2000 and 2001 to reflect the restatements,” said John Jackson, chief financial officer. He said information concerning its internal investigation will be provided to the SEC.

“Operating managers identified a few transactions that, although relatively small in their overall affect on our historical results, the Company felt warranted restatement in order to assure shareholders that the Company's accounts are accurate and transparent,” said Chad Deaton, chief executive officer. “Our focus now is to begin making the necessary changes that takes Hanover to the next level of performance.”

Restating 1999 financial results will reduce revenues by $5.1 million, pre-tax income by $3.1 million and net income by $2.0 million for 1999. The impact of the restatement of the 1999 transactions on 2000 net income is an increase of $0.4 million and the impact on 2001 net income is a decrease of $0.4 million.
