NEWS RELEASE

RITCHIE BROS. AUCTIONEERS ANNOUNCES
FIRST QUARTER RESULTS AND DECLARES DIVIDEND

FOR IMMEDIATE RELEASE: May 2, 2006

VANCOUVER, BRITISH COLUMBIA — Ritchie Bros. Auctioneers Incorporated (NYSE: RBA; TSX: RBA) today announced that the Company’s net earnings for the quarter ended March 31, 2006 were $13.2 million, or $0.38 per diluted weighted average share, compared to $13.7 million, or $0.40 per diluted share, for the equivalent period in 2005. Net earnings for the first quarter of 2005 would have been $10.4 million, or $0.30 per diluted share had after-tax gains of $3.3 million recorded on the sale of excess property, which the Company does not consider part of its normal operations, been excluded. All dollar amounts are presented in United States dollars.

Gross auction sales for the quarter ended March 31, 2006 were a record $572 million, representing a 25% increase over the first quarter of 2005, making this the largest first quarter gross auction sales in the Company’s history. Auction revenues in the first quarter of 2006 were $56.0 million, an increase of 15% compared to the equivalent quarter in the prior year. The Company’s auction revenue rate (auction revenues as a percentage of gross auction sales) was 9.79% in the first quarter of 2006, compared to 10.65% in the same quarter of the previous year.

During the quarter ended March 31, 2006, Ritchie Bros. held 32 industrial auctions at locations throughout North America, Europe, the Middle East, Australia and Mexico and set five regional gross auction sales records, including the largest auction held in the Company’s history in February in Orlando, Florida, which posted gross auction sales of over $113 million. The Company also held 24 agricultural auctions, which generated gross auction sales of $30.4 million, compared to four agricultural auctions with gross auction sales of $4.2 million in the corresponding quarter in 2005.

The Company sold in excess of 47,000 lots from over 6,100 industrial consignments and had more than 52,000 bidder registrations at its industrial auctions during the quarter ended March 31, 2006. Internet bidding continued to enhance the Company’s live auctions, and in the first quarter of 2006 the Company sold nearly $90 million worth of trucks and equipment to on-line buyers using the Company’s rbauctionBid-Live system.

Although the Company’s auctions have varied in size over the last 12 months, the average Ritchie Bros. industrial auction in the 12 month period ended March 31, 2006 attracted over 1,300 bidder registrations (12 months ended March 31, 2005 — 1,300) and featured more than 1,300 lots (12 months ended March 31, 2005 — 1,200) consigned by 185 consignors (12 months ended March 31, 2005 — 168), generating average gross auction sales of approximately $13.5 million per auction (12 months ended March 31, 2005 — $12.0 million).

The Company continued the expansion of its auction site network during the first quarter of 2006, opening new permanent auction sites in Nashville, Tennessee and Buxton, North Dakota. The Buxton site joined Ritchie Bros. network as part of the acquisition of the agricultural auction business of Dennis Biliske Auctioneers. Subsequent to March 31, 2006, the Company completed the acquisition of approximately

140 acres of land near Springfield, Ohio, on which it intends to construct a new permanent auction site. It also held its first sale on its new permanent auction site in Saskatoon, Saskatchewan. The Saskatoon site is expected to hold primarily agricultural auctions.

Peter Blake, the Company’s CEO, commented: “Our results to date in 2006 are evidence to us of our increasing market share. Despite the ongoing tight supply of good quality, late model equipment in many of our regions, we have been able to grow our gross auction sales thanks to the ever-increasing number of buyers and sellers participating in our unreserved auctions. Equipment owners are continuing to find that our unreserved auctions are more efficient than alternative ways of buying and selling trucks and equipment. We are able to create value for our customers by matching local supply with global demand in an open and transparent manner.”

The Company’s Board of Directors today announced the declaration of a quarterly cash dividend of 18 cents per common share payable on June 16, 2006 to shareholders of record on May 26, 2006.

Gross auction sales represent the aggregate selling prices of all items sold at auction and are not presented in the Company’s consolidated financial statements; the comparable financial statement measure is auction revenues, consisting primarily of commissions earned on consigned equipment and net profit on the sale of equipment purchased by Ritchie Bros. and sold in the same manner as consigned equipment.
