Pinterest Files Confidentially for U.S. IPO

Pinterest Inc. has filed confidentially for a U.S. initial public offering and is expected to seek a valuation for the company of at least $12 billion, according to a person familiar with the matter.

The visual search site could list toward the end of June, said the person, who asked not to be identified because the details aren’t public. A final decision on the San Francisco-based company’s IPO plans hasn’t been made, the person said.
