SOUTH PORTLAND — Buoyed by growth in multiple divisions, South Portland-based Wright Express Corp. reports 2010 full-year revenue of roughly $390 million, up 24 percent from 2009.

Net income for the year, however, was $88 million, down from $140 million in 2009.

In a media release, CEO Michael Dubyak attributed the gains to strong existing customer sales and growth of the company’s payment processing, MasterCard and vehicle businesses.

Wright also reported fourth-quarter 2010 gains. During the period, revenue jumped to $114.9 million, a 38 percent increase from the same period in 2009. Net income rose to $18 million during the period, up from $12 million in 2009.

In the fourth quarter, the company serviced 17 percent more vehicles and saw double-digit gains in fuel transactions, payment processing and transaction processing. In addition, MasterCard purchase volume grew 54 percent during the quarter, said the media release.

Wright Express projects first-quarter 2011 revenue will come in between $113 million and $118 million, and full-year 2011 revenue is expected to fall between $497 million and $517 million.
