Overstock.com CEO Taking Temporary Leave of Absence

Overstock.com President Jonathan Johnson named Acting CEO

SALT LAKE CITY — February 12, 2013 — Overstock.com, Inc. today announced that its CEO and Chairman of the Board Dr. Patrick Byrne will be taking a personal leave of absence for medical reasons.  Overstock.com President Jonathan Johnson will serve as Acting CEO during Dr. Byrne’s leave of absence.  Dr. Byrne will remain Chairman of the Board.

Dr. Byrne, in recent years, had undergone various procedures regarding cardiac issues that may stem from his earlier episodes of cancer, and his leave of absence is associated with these cardiac issues.

“We’ve worked hard this past year and delivered good results; our team is executing exceptionally well, putting points on the board. We have set our company plan for 2013 and I have great confidence in my colleagues to execute it,” said Byrne.

Johnson has been with the company for over ten years, and has served as President since July 2008.  He also serves as corporate secretary.  Prior to becoming President, he served in various roles including Senior Vice President and General Counsel. “My colleagues and I will continue to execute on our plan,” said Johnson, “and we look forward to the time when Patrick returns to the helm.”
