Patrick Byrne Returns to Helm at Overstock.com

Byrne resumes as CEO; Jonathan Johnson maintains executive duties and has been nominated to the board

SALT LAKE CITY — April 11, 2013 — Overstock.com, Inc. (NASDAQ: OSTK) announced today that Dr. Patrick M. Byrne has resumed duties as company CEO.

In February, Byrne took a medical leave of absence to address cardiac issues thought to be associated with cancer treatments received much earlier in his life.  Following rest and treatment, Byrne now returns to the company he founded.

Byrne said, “It was good to get away, take some time off, and attend to some things that needed looking after, but it’s great to be back, and I look forward to serving our shareholders once more. I wish to extend my gratitude to Jonathan, who has done a fine job in my absence, and in my view is ready to start providing direction at a board level, while retaining executive responsibilities for a large section of the company.”

During his leave, Byrne retained his position as chairman, but appointed Jonathan Johnson, formerly president, as acting CEO.  “Everyone at the company is pleased Patrick is back, in good shape, and able to continue to direct the business of the company,” Johnson said.

Recently, Johnson was nominated to stand for election to the board of directors at the company’s annual stockholders’ meeting in May.  The company’s proxy materials note that if Johnson is elected, the board intends to appoint Johnson as executive vice chairman of the board.
