Intergraph Raises Second Quarter and Fiscal Year 2006 Financial Guidance

HUNTSVILLE, Ala., July 11, 2006 -- Intergraph Corporation (NASDAQ: INGR), a leading global provider of spatial information management (SIM) software, today announced that it expects financial results for the second quarter ended June 30, 2006 and fiscal year ending December 31, 2006 to be higher than the previous guidance provided by management in April.

Revenue for the second quarter is now expected to be between $151 and $153 million, above the previously indicated range of $145 to $147 million.  Operating income for the second quarter is now estimated to be in the range of $11.3 to $12.3 million, compared to the previous guidance of $5.0 to $7.0 million.  The Company expects to report a restructuring charge of approximately $5.7 million in the second quarter of 2006, compared to the previous guidance of $4.5 to $5.5 million.  Operating income before restructuring (a non-GAAP financial measure) for the second quarter is now expected to be between $17.0 and $18.0 million, above the previously indicated range of $10.5 to $11.5 million.

Revenue for fiscal year 2006 is expected to be in the range of $600 to $610 million, consistent with the previous guidance.  Operating income for fiscal year 2006 is now estimated to be between $48.6 and $52.6 million, above the previously indicated range of $42.8 to $47.8 million.  The Company estimates total restructuring charges of approximately $10.4 million for the six months ended June 30, 2006 and does not expect to report restructuring charges in the second half of fiscal year 2006.  Operating income before restructuring (a non-GAAP financial measure) for fiscal year 2006 is now expected to be between $59.0 and $63.0 million, above the previously indicated range of $53.0 to $57.0 million.

"Our recent operating performance underscores the progress of Intergraph's business transformation efforts and solid execution of our Strategic Plan.  The increased financial guidance reflects better than anticipated second quarter results and continued operating improvements in both our PP&M and SG&I divisions," said R. Halsey Wise, Intergraph President & CEO.  "In addition, we are pleased to announce the completion of our organizational realignment and associated restructuring charges.  We completed the organizational realignment within our original schedule by the end of the second quarter of 2006 and expect to realize efficiency improvements and annual gross cost savings from these restructuring efforts of approximately $32 million, above our previous estimate of $26 to $29 million.  We believe the organizational realignment and continued investments in new products and capabilities will improve our ability to serve our customers and better position us to capitalize on our attractive market opportunities and Intergraph's increased relevance in the current global environment."

As previously announced, the Company will report actual second quarter financial results on Wednesday, July 26, 2006 after market close.  The Company's management will host a conference call to discuss the second quarter results on Thursday, July 27, 2006 at 11:00 a.m. EDT.  Investors are invited to listen to a live Webcast of the conference call through the investor relations section on Intergraph's Website at www.intergraph.com/investors.
