Procter & Gamble Co., whose chief executive officer is under pressure from activist investor Bill Ackman, raised its 2013 earnings forecast after gaining U.S. market share and posting quarterly profit that beat analysts’ estimates.

Net income more than doubled to $4.06 billion, or $1.39 a share, in the second quarter ended Dec. 31, Cincinnati-based P&G said Friday in a statement. Excluding some items, profit of $1.22 a share topped the $1.11 average of estimates compiled by Bloomberg.
