EMC

(EMC)

shares slipped on Wednesday after reporting first-quarter results that missed Wall Street's top- and bottom-line estimates.

Excluding items, EMC earned 39 cents a share, up from 37 cents a share in the prior year's quarter. Analysts surveyed by

Yahoo! Finance

were looking for earnings of 40 cents a share.

Revenue from EMC's Information Storage business grew 3% year over year, with high-end storage sales climbing 10% from the year-ago quarter. The company's RSA Security division grew its revenue 12% over the same period.

also announced plans to make a strategic investment of about $105 million in Pivotal, a specialist cloud company created by EMC and VMware. GE's investment represents a 10% equity stake in the company.
