Verizon brought in revenue of $28.6 billion, a 3.7% increase on the prior year's quarter. Analysts surveyed by Thomson Reuters were looking for a top line of $28.558 billion. Verizon earned 64 cents a share, a 12.3% increase from the same period last year, and in line with analysts' forecasts. "Verizon delivered another strong quarter of earnings growth and cash generation, and we remain on track to meet our financial objectives and produce solid double-digit earnings growth for the year," noted Verizon CEO Lowell McAdam, in a statement released before market open Thursday. Operating income margin for the wireless division was 30.8% during the second quarter, a record for the company.
