Jacobs also announced revenues of $1.7 billion for the first quarter of fiscal 2006 ended December 31, 2005. This compares to revenues of $1.3 billion for the first quarter of fiscal 2005. Jacobs also announced backlog totaling $9.0 billion at December 31, 2005, including a technical professional services component of $4.5 billion. This compares to total backlog and technical professional services backlog of $8.0 billion and $4.5 billion, respectively, at December 31, 2004.

Commenting on the results for the first quarter of fiscal 2006, Jacobs Chairman and CEO Noel G. Watson stated, “Fiscal 2006 is off to a good start. Our backlog continues to grow steadily. We were awarded several important contracts during the quarter, and our prospect list remains strong.”

Commenting on the results for the first quarter of fiscal 2006 and on the Company’s earnings outlook for the remainder of the fiscal year, Jacobs Chief Financial Officer John W. Prosser, Jr. stated, “With the good results of our first quarter, we now expect this year’s growth rate to approach 20 percent before the effects of SFAS 123R.”

The following table reconciles the Company’s reported GAAP net earnings and earnings per share to the non-GAAP financial measure (in thousands, except earnings per share):
