Ritchie Bros. topped analysts' first-quarter estimates and remains a leader in a highly fragmented industry -- which spells growth opportunity.

In many ways, Ritchie Bros. Auctioneers (NYSE:RBA) is the eBay of heavy machinery. Its auction service helps equipment sellers obtain the highest net return on the sale of their equipment and trucks by using its experience and global bidding audience. The company has a dominant position in the market, and there's plenty of growth to be had, as the industry is extremely fragmented. For instance, used equipment is estimated to be more than a $360 billion market annually, and Ritchie Bros.' leading market share reaches only about $4.2 billion of that amount.

The long-term future growth opportunity looks enticing, and its first quarter of 2016 was solid. Here are some key figures.

Q1 highlights

Ritchie Bros. posted more than $1 billion of gross auction proceeds during the first quarter, which was the first time the company had topped that mark during a Q1. Revenue jumped 14% compared with last year's period, to $131.9 million, well ahead of analysts' estimates of $115.4 million. Revenue would have checked in about $3 million higher if foreign exchange rates had remained consistent with values in 2015.
