DigitalGlobe

Following months of dry activity in the IPO market, signs of investors' confidence in new companies are starting to emerge. DigitalGlobe Inc. , a satellite imagery provider to the government and commercial enterprises, raised $279.3 million in its initial public offering on Wednesday, in a deal led by underwriters Morgan Stanley and JPMorgan.  Shares of DigitalGlobe, which will trade at the NYSE under the symbol "DGI," were priced at $19 per share.  The estimated range had been $16 to $18 per share.

The Longmont, Colorado-based company brings the count of initial public offerings on a US exchange to five so far this year.  Of those deals, four belong to the tech sector.  Other companies in the pipeline expected to be unveiled this year include SolarWinds, a network management software corporation, and Open Table, an online restaurant company.
