**Explanatory Note**

As previously reported in our Current Report on Form 8-K filed with the Securities and Exchange Commission on January 26, 2023 (the "Initial Form 8-K"), on January 21, 2023, Marianne De Backer, Ph.D., notified us of her decision to resign from our board of directors. The effective date of Dr. De Backer's resignation had not been established at the time of the Initial Form 8-K. The effective date of Dr. De Backer's resignation has now been determined, and accordingly we are amending the Initial Form 8-K to include that information.

In accordance with Rule 12b-15 of the Securities Exchange Act of 1934, as amended, the complete text of Item 5.02 of the Initial Form 8-K, as amended hereby, is set forth below.

**Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.**

**(b)** On January 21, 2023, Marianne De Backer, Ph.D., notified us of her decision to resign from our board of directors as a result of her recent appointment as Chief Executive Officer of Vir Biotechnology, Inc., and in consideration of her additional time commitments associated with such position, as well as the "overboarding" policies of shareholder advisory firms. In connection with such notice, Dr. De Backer informed us the effective date of her resignation had not been determined but it would likely be late in the first quarter or in the second quarter of 2023.

On March 27, 2023, Dr. De Backer notified us that her resignation from our board of directors will be effective on June 23, 2023.
