ROCKVILLE, MD, February 7, 2024 – I-Mab (the “Company”) (NASDAQ: IMAB), a global biotech company exclusively focused on bringing highly differentiated immunotherapies and biologics for cancer treatment to patients around the world, today announced that as part of its strategy to become a U.S.-based biotech, its Chinese subsidiaries have entered into definitive agreements with I-Mab Biopharma (Hangzhou) Co., Ltd. (the “Hangzhou Company”), an unconsolidated affiliate of the Company, and a group of China-based investors to divest the Company’s assets and business operations in China.

“This agreement to divest our operations in China marks an important milestone for I-Mab in bringing a greater focus on the U.S. and ex-China markets,” said Xxx Xxxxxx, Director and Chief Executive Officer of I-Mab. “Importantly, we believe that this transaction allows us to reduce significant operational costs and enables us to reallocate our capital on current key priorities and new potential opportunities in further strengthening our portfolio while maintaining a strong balance sheet.”

Pursuant to the definitive agreements, the Company will transfer 100% of the outstanding equity interest in I-Mab Biopharma Co., Ltd. (“I-Mab Shanghai”), a wholly owned subsidiary of the Company that operates the Company’s business in China, on a cash-free and debt-free basis, to the Hangzhou Company for an aggregate consideration of the RMB equivalent of up to US$80 million, contingent on the Hangzhou Company group’s achievement of certain future regulatory and sales-based milestone events. The Company also retains a right of first negotiation outside of Greater China related to three future investigational new drug candidates.

The definitive agreements also provide that the Company’s wholly owned subsidiary, I-Mab Biopharma Hong Kong Limited (“I-Mab Hong Kong”), will transfer the equity interests it holds in the Hangzhou Company to certain participating shareholders of the Hangzhou Company in exchange for extinguishment of the existing repurchase obligations owed by I-Mab Hong Kong to those shareholders in the amount of approximately US$183 million. The total amount of potential repurchase obligations owed by I-Mab Hong Kong and the Company to the non-participating shareholders of the

Hangzhou Company upon the closing of the transaction is expected to range from US$30 million to US$35 million, an amount that includes actual or potential claims in legal proceedings by the non-participating shareholders against I-Mab Hong Kong and the Company in connection with the aforementioned transaction.

The Special Committee to the Board of Directors (the “Board”) of the Company, consisting of Xx. Xxxxx Xxxx-xxxx Xxxx, Dr. Xxxx He, and Mr. Xxxxx Xxxx, each of whom is an independent and disinterested director of the Board, led the evaluation and negotiation of the transaction on behalf of the Company. Xxxxx, LLC served as an independent financial advisor to the special committee and issued a fairness opinion. The Board, acting upon the unanimous recommendation of the special committee, resolved that the proposed transaction is in the best interest of I-Mab and is fair from a financial point of view to the Company and approved the transaction. The transaction is subject to closing conditions and is expected to close by the end of March 2024.

Once the transaction is completed, the Hangzhou Company will acquire I-Mab drug assets in China, including the Greater China rights for eftansomatropin alfa, felzartamab, uliledlimab, givastomig, and lemzoparlimab; bear all future development costs of these assets; and be responsible for the operations of the research & development (R&D) center of I-Mab Shanghai and the manufacturing facility of the Hangzhou Company.

Concurrent with the entry into definitive agreements and to support the ongoing strategic partnership, the Company participated in the Series C fundraising of the Hangzhou Company for an equity interest subscription of US$19 million in cash. Immediately after the closing of the transaction, the Company will directly and through I-Mab Hong Kong own a total of less than 10% of the Hangzhou Company’s registered capital.

To further its transition to a U.S.-based biotech company, I-Mab announced certain management and personnel changes. Xxxxxx Xxxxx, M.D., has accepted the appointment as the Interim Chairperson of the Company, as Xxxxxx Xxxx, M.D., Ph.D., steps down from the Board, effective February 10, 2024, to lead the Hangzhou Company. Xxxxxx Xxx, M.D., Ph.D., will step down from the Board and resign from his executive position with the Company, effective February 10, 2024.
