New York ? Sears Holdings Corp., the third-largest U.S. retailer, named Aylwin B. Lewis as its new chief executive officer and president Thursday while reporting that its second-quarter earnings rose 4.5 percent but missed expectations.

Sears Holdings, which was formed through Kmart Holding’s acquisition of Sears, Roebuck & Co. on March 24, said former CEO Alan J. Lacy would continue to serve as vice chairman and a director, and as a member of the office of the chairman.

Lewis had served as president and CEO of Kmart and Sears retail, and as a director.

Sears said second-quarter net income grew to $161 million, or 98 cents per share, from $154 million, or $1.54 per share, a year ago. The latest period includes $42 million of restructuring costs related to the merger. Sears did not provide a per-share cost of the $42 million charge.

Total revenue rose to $13.19 billion from $4.8 billion last year, due to the addition of Sears revenue of $8.6 billion.
