I/O ANNOUNCES NEW FOURTH QUARTER
EARNINGS RELEASE AND CONFERENCE CALL SCHEDULE

HOUSTON – MARCH 3, 2006 – Input/Output, Inc. (NYSE: IO) announced today that it will release 2005 fourth quarter and year end results on Wednesday, March 15, 2006 after the market closes. In conjunction with the release, I/O has scheduled a conference call, which will be broadcast live over the Internet, for Thursday, March 16, 2006 at 9:00 a.m. Eastern Time (8:00 a.m. Central).

     I/O had originally scheduled its earnings release for March 8, 2006, but delays resulting from the process of completing the audit of I/O’s 2005 consolidated financial statements have caused I/O to reschedule the release of its financial results for 2005. This delay is expected to also result in I/O delaying the filing of its Annual Report on Form 10-K for the year ended December 31, 2005. If delayed, I/O would expect to file its Form 10-K for 2005 no later than March 31, 2006.

     In previous press releases, I/O management had anticipated 2005 earnings to range between $0.12 and $0.25 per diluted share. I/O management continues to anticipate that its reported earnings for 2005 will be consistent with its previously-announced range.
