Operating income rose to $5.8 billion from $5.3 billion a year ago, while adjusted operating income increased to $6.1 billion. Net income for the quarter slipped to $4.2 billion from $4.4 billion, reflecting the absence of income tied to AT&T’s former stake in satellite broadcaster DIRECTV. Adjusted EBITDA for the year rose to $46.4 billion from $44.8 billion, while free cash flow increased to $16.6 billion from $15.3 billion. Consumer Wireline continued to benefit from fiber expansion, with 283,000 fiber net adds in the quarter and fiber revenue up 13.6 percent. AT&T said customer convergence continued to improve, with 42 percent of fiber households also subscribing to AT&T wireless services.
