On March 26, 2014, the Board of Directors of Lumber Liquidators Holdings, Inc. (the “Company”) took action to increase the number of directors on the Company’s Board of Directors from eight to nine. In connection with that action, the Board appointed Nancy M. Taylor to serve, effective April 1, 2014, as a new director in the class of directors whose current terms expire in 2015. The Board anticipates naming Ms. Taylor to serve on one or more committees of the Board, but at the time of this Form 8-K, the Board has not determined the committee(s) to which she will be named. The Company will file an amendment to this Form 8-K naming those committees once they are determined.

Ms. Taylor currently serves as the President and Chief Executive Officer of Tredegar Corporation, serving in such roles since January 2010, and is a member of Tredegar’s Board of Directors. Prior to assuming her current positions, she was Executive Vice President of Tredegar responsible for corporate business development in addition to her role as President of Tredegar Film Products. Previously, she served in roles of increasing responsibility at Tredegar since she joined the company in 1991. Before joining Tredegar, she was an associate at the law firm of Hunton & Williams. Ms. Taylor received a B.A. degree at College of the Holy Cross and a law degree from Catholic University of America.

Ms. Taylor’s compensation will be consistent with the compensation policies applicable to the Company’s other non-employee directors as disclosed in our Proxy Statement for our 2014 Annual Meeting of Stockholders.
