Jacobs Engineering Group Inc. Reports Fiscal 2004 Earnings

PASADENA, CALIF. - Jacobs Engineering Group Inc. (NYSE: JEC) today announced net earnings of $129.0 million, or $2.25 per diluted share, on revenues of $4.6 billion for its fiscal year ended September 30, 2004. This compares to net earnings of $128.0 million, or $2.27 per diluted share, on revenues of $4.6 billion for fiscal 2003.

For the fourth quarter of fiscal 2004, Jacobs reported net earnings of $30.5 million, or $0.53 per diluted share, on revenues of $1.2 billion. This compares to net earnings of $33.5 million, or $0.59 per diluted share, on revenues of $1.1 billion for the fourth quarter of fiscal 2003.

Jacobs also announced backlog at September 30, 2004, totaling $7.5 billion, including a technical professional services component of $4.0 billion. This compares to total backlog and technical professional services backlog of $7.0 billion and $3.4 billion, respectively, at September 30, 2003.

Commenting on the results for the year, Jacobs Chairman and CEO Noel G. Watson stated, “Fiscal 2004 was a disappointing year for us with essentially flat profits on a year over year basis.

Prosser, Jr. stated, “For the coming year, we are maintaining our guidance in the range of $2.40 to $2.70 per share.
