Twitter squawks as user growth and guidance come up light SHARE Twitter Inc. took a beating in after-hours trading today, its stock down more than 11% after missing expectations on user growth and offering lower-than-expected guidance for the next three months. That took the sheen off an otherwise solid performance. Twitter reported a first-quarter profit before certain costs such as stock compensation of 16 cents per share on revenue of $1.04 billion, up 28% from a year ago. Wall Street had modeled an adjusted profit of 14 cents per share on revenue of $1.03 billion. Twitter said its advertising revenue rose 32% from a year ago, to $899 million, while data licensing sales rose 9%, to $137 million.
