In connection with its initial public offering in October 2014, Wayfair Inc. (the “Company”) employees agreed not to sell securities of the Company during a contractual lock-up period that ended on March 31, 2015, at which time Company policy generally restricted employees from selling securities of the Company until May 13, 2015 other than pursuant to previously adopted Rule 10b5-1 trading plans.

All executive officers and many employees of the Company have entered into currently effective trading plans adopted under Rule 10b5-1. Employees with previously adopted Rule 10b5-1 trading plans were able to sell under those plans on or after April 1, 2015. Approximately 1 million shares of the Company’s common stock are held by employees who have not adopted trading plans.

The information in this report shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as expressly provided by specific reference in such a filing.
