What: Shares of E2open (NASDAQ:EOPN) have plunged today by as much as 28% after the company reported fourth-quarter results.

So what: Non-GAAP revenue in the fourth quarter totaled $18.1 million, shy of the $19.7 million in adjusted sales that investors were expecting. The bottom line also registered a miss, with the adjusted loss of $0.06 coming in below the consensus estimate of a $0.05 per share non-GAAP net loss. CEO Mark Woodward's comments about the company adding a record number of new customers in the quarter didn't make investors feel any better.

Non-GAAP net loss is guided to $0.18-$0.22 per share, similarly falling short of the $0.03 per share loss that most were expecting. Full-year sales outlook is for $75 million to $77 million.
