FLIR Systems Announces First Quarter

2005 Financial Results; Reaffirms 2005 Guidance

Net Earnings Increase 16%

PORTLAND, OR – April 20, 2005 — FLIR Systems, Inc. (NASDAQ:FLIR) announced today that net earnings in its first fiscal quarter ended March 31, 2005 increased by 16% to $14.7 million, from $12.7 million in the first quarter of 2004. Revenue for the quarter was $108.3 million, approximately unchanged from $108.9 million in the first quarter of 2004. Earnings from operations declined 3% to $21.1 million from $21.9 million for the first quarter of 2004. Net earnings per fully diluted share were $0.19, compared with $0.17 in the first quarter of 2004. All per share amounts have been adjusted to reflect the 2-for-1 stock split that was effective on February 2, 2005.

Revenue from the Company’s Thermography Division increased 18% over the first quarter last year, primarily due to continued strong international sales, and strong demand for the company’s E-Series camera line.

Revenue from the Company’s Imaging Division declined by 9% due to slower order activity from the US Government and delays in the receipt of export licenses to certain international customers.

The backlog of orders grew by 4% to approximately $165 million at March 31, 2005, as compared to $159 million at December 31, 2004.

Cash generated from operations totaled $12 million for the first quarter of 2005. At March 31, 2005, the Company had cash and cash equivalents of approximately $126 million.

“Our financial performance in the first quarter was slightly below our internal expectations, largely as a result of slow order placement activity by the US Government and delays in receiving certain export licenses. However we expect improved order activity as the year progresses, and thus remain comfortable with our outlook for the full year” said FLIR President and CEO Earl R. Lewis. “Our current expectation for the full year 2005 is for earnings per share in the range of $1.12 to $1.18, and revenue in the range of $545 million to $560 million.”
