Francesca's Holdings says that it fired its chief financial officer, saying that he improperly communicated company information through social media.
The women's clothing retailer also raised its fiscal first-quarter earnings estimate, citing better-than-expected sales.
Its shares rose about 2 percent in morning trading.
The Houston-based company said it terminated Gene Morphis' employment after an investigation by the board that was launched after the company discovered the activity late last week.
Francesca's didn't say in a news release what specific kind of company information Morphis improperly released, or through what form of social media he released it. A company spokeswoman didn't immediately return a call seeking comment.
Morphis could not be reached for comment.
