EXPLANATORY NOTE

This Amendment No. 1 to Schedule 13D (this “Schedule 13D/A”) amends and restates the statement on Schedule 13D originally filed with the Securities and Exchange Commission on January 3, 2019 (the “Schedule 13D” or the “Prior Filing”), with respect to Class A Ordinary Shares, $1.00 par value per share (the “Ordinary Shares”), of Aptorum Group Limited, a Cayman Islands exempted company with limited liability whose principal place of business is in Hong Kong (the “Issuer”). The Issuer’s principal executive office is located at 17th Floor, Guangdong Investment Tower, 148 Connaught Road Central, Hong Kong . Unless otherwise indicated, each capitalized term used but not otherwise defined herein shall have the meaning assigned to such term in the Schedule 13D. From and after the date hereof, all references in the Schedule 13D to the Schedule 13D or terms of similar import shall be deemed to refer to the Schedule 13D as amended and supplemented by this Schedule 13D/A.

The purpose of this filing is to revise the beneficial ownership previously reported for Darren Lui, one of the Reporting Persons included in the Schedule 13D. The Prior Filing inaccurately reported that Mr. Lui was deemed to beneficially own the Ordinary Shares held by his brother and sister; Mr. Lui does not have any voting or dispostive power with respect to the Ordinary Shares held by such relatives and therefore we are filing this Schedule 13D/A to remove reference to same from his holdings and update certain other related information in the Prior Filing.

Information set forth in response to any item of the Prior Filing, as amended and restated by this Amendment No. 1 (as so amended and restated, this “Schedule”), shall be deemed to be a response to all other items hereof to which such information is relevant.

CUSIP Number: G6096M106
