The following paragraph is added as the penultimate paragraph of Item 4 of the Schedule 13D:
On May 23,2022, Golden Meditech Stem Cells (BVI) Company Limited (“GM Stem Cells”), Magnum Opus International Holdings Limited (“Magnum Opus”) and Yuen Kam (“Mr. Kam”, together with GM Stem Cells and Magnum Opus, the “GM Parties”) filed a Schedule 13D with the U.S. Securities and Exchange Commission making a number of claims including that GM Stem Cells has a right to shares owned by the Investor. These claims are false. In response to the false statements made by Mr. Kam, the Investor published a press release that highlighted the following. First, Mr. Kam controls Cellenkos through GM Stem Cells. The Investor disclosed evidence in the ongoing legal proceedings in the Cayman Islands that Mr. Kam is in a relationship, and has children with, the current chairwoman of the Issuer (Ting Zheng). As a result, the Issuer is unable to continue to assert that the acquisition of Cellenkos is an arms’ length commercial transaction in the best interests of the Issuer rather than for the benefit of Mr. Kam and Ms. Zheng. It is clear that Mr. Kam has significant incentives to push the Cellenkos transaction through to the detriment of the Issuer’s shareholders. Second, the alleged share charge agreement in the GM Parties’ Schedule 13D filing is forged. Mr. Kam is now attempting to circumvent the legal proceedings by trying to steal the Investor’s shares using fraudulent share charges and loan documents. There is no credible claim to the Investor’s share ownership and therefore no impact to the Investor’s ability to exercise its rights as shareholders and to work with any other shareholder to safeguard their collective rights as shareholders. Third, the Investor has taken legal action against Mr. Kam related to these fraudulent claims and expect quick resolution in the Investor’s favor. The actions taken by Mr. Kam have no impact on the Investor’s share ownership, the ongoing legal proceedings or the Investor’s commitment to stop the Cellenkos transaction.
