The social media company known for its disappearing messages got crushed again by a challenging ad market, and the stock fell by double digits on Wednesday. Revenue in the quarter was flat at $1.3 billion, which matched analyst estimates, and the company's adjusted earnings per share of $0.14 fell from $0.22 in the quarter a year ago -- though that still beat the consensus at $0.11. It lost $289 million on a GAAP basis, and the company continues to spend aggressively on share-based compensation, despite promises to reel it in.
