Online measurement firm comScore is planning to raise as much as $86.3m in a listing on Nasdaq.

The company is yet to decide how many shares it will sell and for how much, but the move is widely expected to fund an expansion of its services outside the US.

In a statement, it said it had appointed Credit Suisse Securities as sole book-running manager for the IPO, while Deutsche Bank Securities, William Blair & Co., Friedman Billings Ramsey & Co. and Jefferies & Co. have been recruited as co-managers.

Founded in 1999, comScore has become one of the leading researchers into consumer behaviour on the web – although its metrics have come under scrutiny in recent months amid complaints from major sites and rising adoption of new technologies like Ajax.

In a filing with the US Securities and Exchange Commission, the company hinted that it would be looking abroad for a good proportion of future revenue growth, and declared that 9% of its sales came from outside the US last year.

Other nuggets of info include:

  • The company’s turnover was $66.3m last year.
  • It was profitable in each quarter in 2006, but made losses in 2005 and 2004 and had debt of almost $100m at the end of last year.
  • 75% of comScore’s 2006 sales came through subscriptions.
  • 12% came from one company – Microsoft.
  • Future services could include metrics on online video consumption and mobile internet usage.
  • It has received $86m since its formation from various private investors.
