Costa Mesa-based Experian Information Solutions Inc. saw a 10% lift in revenue for the year through March, for a total of $2.09 billion.

Experian Information operates as the North America division of Dublin, Ireland-based Experian PLC, which also has operations in Latin America, Asia and the U.K.

The Costa Mesa-based unit accounted for about 47% of the total revenue for the parent. Its earnings before interest and taxes totaled $658 million, up 18% from a year earlier. That makes up 56% of total earnings before interest and taxes for all of Experian’s continuing operations, which topped $1.17 billion, up 19% from a year ago.

“We saw a positive lift ... fueled by an improved lending environment in the U.S. and investments in new products and data sources," said Victor Nichols, chief executive of Experian North America.

The Costa Mesa office employs more than 1,200 workers.

Part of the recently revenue growth came from the $185 million buy of Austin, Texas-based Medical Present Value Inc. last June, which helped the company expand in the medical payments industry.
