FLIR Systems Announces Preliminary Third Quarter

2005 Earnings and Revenue Expectations

Company Revises full Year Guidance

PORTLAND, Ore. – October 10, 2005 — FLIR Systems, Inc. (NASDAQ:FLIR) today announced it expects revenue for the quarter ended September 30, 2005 to be approximately $112 million, and net earnings per fully diluted share for the quarter to be in the range of $0.21 to $0.23. Backlog at September 30, 2005 is expected to be approximately $200 million to $205 million, an increase of $30 million to $35 million compared with the backlog at June 30, 2005. The company will announce full third quarter financial results on October 19, 2005.

Full Year Earnings and Revenue Guidance

The Company also revised its full year 2005 financial outlook. Management currently expects revenue for the full year 2005 to be in the range of $510 million to $520 million, and net earnings per fully diluted share to be in the range of $1.12 to $1.17. The Company had previously announced its expectations that revenue would be in the range of $545 million to $555 million and net earnings per fully diluted share would be in the range of $1.17 to $1.22.

Commenting on the third quarter results and the outlook for the year, Earl Lewis, Chairman President and CEO of FLIR, stated “third quarter revenue was disappointing, due largely to lower than expected book and ship business in our Imaging division, and lower than expected European revenue in our Thermography division. Our Imaging division experienced very good bookings in the quarter, resulting in a record level of backlog. While this strong order flow supports our positive long term outlook, we do not expect to recoup the third quarter revenue and earnings shortfall in the fourth quarter, and are thus reducing our revenue and EPS outlook for the year.”
