• Upon closing, the transaction would secure global IP rights for NKGen.
• NKGen and its partners can begin to commercialize troculeucel in Korea, Japan and other markets where natural-killer (“NK”) cell therapy is already legal.
• NKGen proposal included up to $18 million in committed funding.
• Closing expected in 1Q 2025.

SANTA ANA, Calif., Dec. 02, 2024 (GLOBE NEWSWIRE) -- NKGen Biotech, Inc. (Nasdaq: NKGN) (“NKGen” or the “Company”), a clinical-stage biotechnology company focused on the development and commercialization of innovative autologous and allogeneic natural killer cell therapeutics, today announced it has been selected as the preferred stalking horse bidder for NKMax Co., Ltd. (“NKMax”) in NKMax’s court-managed rehabilitation process in South Korea. NKMax filed for rehabilitation in South Korea, roughly similar to Chapter 11 in the US, on April 18, 2024, and currently holds an approximate 25% equity interest in NKGen. NKGen’s proposal included up to $18 million in committed funding from a third-party investor. As is typical in US bankruptcies, there will now be a public offering process, with NKGen having final right of first refusal on any other qualified offers, with the final decision and ultimate rehabilitation plan approved by NKMax’s creditors and the court expected in February 2025 and closing thereafter (the “Acquisition”). NKGen and its financing partners expect to hold a majority of the equity of NKMax at closing.

NKMax currently holds master global rights to the intellectual property (“IP”) for troculeucel (formerly known as SNK01) and other proprietary IP that is licensed to NKGen for markets outside Asia. Such an acquisition is expected to put global rights under the control of NKGen. Prior to entering into the rehabilitation process, NKMax announced plans and commenced initial groundwork to commercialize the troculeucel treatment for Alzheimer’s and other neurodegenerative diseases in Japan and South Korea, where such NK cell treatment is legal already. Additional production capacity at NKMax’s GMP facility will be an added benefit which could help accelerate production for US trials.

“As we have made tremendous progress in our clinical program especially with the launch of our phase II trial for moderate stage Alzheimer’s disease, we felt that it was essential for us to preserve the very close scientific and clinical partnership with the NKMax team, rather than have NKMax acquired by someone without any cell therapy knowledge or experience”, commented Paul Y. Song, MD, Chairman and CEO of NKGen Biotech. “As we continue to work towards US FDA approval, we will be able to begin to commercialize troculeucel in countries like Japan, Thailand, Malaysia, Mexico and others where an autologous non-genetically modified cell therapy is considered as a legal treatment and already readily available. We believe that we will be much stronger and will deliver more value for our patients and shareholders when operated as one global team.”

NKGen does not believe the NKMax rehabilitation process has had any material negative impact on NKGen’s business or prospects.

About Troculeucel

Troculeucel is a novel cell-based, patient specific ex vivo expanded autologous natural killer (“NK”) cell, immunotherapeutic drug candidate. NKGen is developing troculeucel for the treatment of neurodegenerative disorders and a broad range of cancers. Troculeucel is the International Nonproprietary Name (“INN”) for SNK01 assigned by the World Health Organization (“WHO”). The WHO INN approval of troculeucel establishes a universally recognized nonproprietary drug name for SNK01 and marks a significant step on our journey toward bringing this therapy to market.
