"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.
