Time Warner — AT&T will buy the media giant for $85.4 billion in cash and stock, worth $107.50 per share compared to a Friday close of $89.48. Lawmakers are already promising heavy scrutiny of the deal because of competitive concerns. Separately, AT&T reported adjusted quarterly profit of 74 cents per share, matching estimates, and raised its dividend by a penny to 49 cents per share.
3M — 3M was upgraded to "overweight" from "equal weight" at Barclays, based on a recent pullback and a recovery in emerging markets, where 3M has significant exposure.
