TransUnion said on Thursday that its initial public offering was priced at $22.50 per share, meaning the company is valued at an estimated $4 billion.
In a news release, the credit bureau said it would receive net proceeds of about $626.5 million. Company officials said TransUnion sold 29.5 million shares in the offering and could sell an additional 4.4 million if an over-allotment is fully exercised.
The IPO comes three years after the private equity firm Advent International and the private equity arm of Goldman Sachs agreed to buy TransUnion from Madison Dearborn Partners, a private equity firm based in Chicago, and from the Pritzker family. That deal, announced in February 2012, valued TransUnion at more than $3 billion.
TransUnion posted revenue of $1.3 billion in 2014 and narrowed its net loss to $12.5 million last year from $35.1 million in 2013.
TransUnion, based in Chicago, provides a variety of information services for businesses and consumers, including consumer credit reporting, automotive valuation data and analytic services for risk management. It operates in 33 countries in Africa, Asia, Latin America and North America.
The company was founded in 1968 as a parent company for the Union Tank Car Company, a railcar leasing company, and it expanded into credit reporting a year later.
TransUnion helps businesses analyze data related to its consumers, verify identities and investigate potential fraud. It also enables consumers to view their credit profiles, manage personal information and guard against identity theft.
