Please also address this comment with your interim financial statements. 18. Condensed Financial Information of the Parent Company, page F-40 9. We note your response to comment 28 in which you state that the parent company also carries out research and development activities for new drug discovery. Please help us understand how this statement is consistent with the disclosures made in the Form F-1. In Peter (Peizhi) Luo Adagene Inc. November 10, 2020 Page 3 this regard, we note on page 10 that the parent company, Adagene Inc., was incorporated in February 2011 under the laws of the Cayman Islands as an offshore holding company. In December 2011, Adagene (Suzhou) Limited was incorporated in China, through which you commenced research and development activities in China. On page 73, you state that substantially all of your business operations are in China. On page 81, you state that you are an offshore holding company conducting your operations in China through your PRC subsidiary and that you make loans to the PRC subsidiary. Further, we note that the auditors are located in and organized under the laws of the PRC. As such, it remains unclear why you continue to reflect operating activity (contract liabilities, revenues, research and development expenses) in your standalone financial statements as that of the parent company rather than of the subsidiaries formed to conduct the operations of the entity. It further remains unclear how you are (1) able to recognize income from equity method investees, as no profits have been recognized, and (2) recognize loans to and from your subsidiaries as operating activities as you are stated to be a holding company with no stated operating activities located in the Cayman Islands. Please advise and revise the disclosures and presentations in the document accordingly. You may contact Tracey Houser at 202-551-3736 or Terence O'Brien at 202-551-3355 if you have questions regarding comments on the financial statements and related matters. Please contact Jason Drory at 202-551-8342 or Dorrie Yale at 202-551-8776 with any other questions.
