Explanatory Note:

Due to a printer error, on February 4, 2022, a Schedule 13G was inadvertently filed by United Therapeutics Corporation and Lung Biotechnology PBC (together, the “Reporting Persons”) under the CIK of Celularity Operations Inc. as the Subject Company (the “Original Filing”). The correct Subject Company was Celularity Inc., and this Amendment No. 1 (“Amendment No. 1”) is being filed to clarify that the Reporting Persons hold no securities in Celularity Operations, Inc.
