F1	Grant of restricted stock units. The restricted stock units vest in four equal installments, assuming continuous service on each vesting date, as follows: March 29, 2024; March 29, 2025; March 29, 2026; and March 29, 2027.
F2	Includes 2,500 shares acquired under the Assembly Biosciences, Inc. Amended and Restated 2018 Employee Stock Purchase Plan on November 14, 2022.
F3	The sale reported on this Form 4 represents shares sold by the reporting person to cover tax withholding obligations in connection with the vesting and settlement of Restricted Stock Units ("RSUs"). The sale is mandated by an administrative rule adopted by the Compensation Committee of the Issuer's Board of Directors that requires the satisfaction of tax withholding obligations to be funded by a "sell-to-cover" transaction and does not represent a discretionary transaction by the reporting person.
F4	The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $0.7795 to $0.89, inclusive. The reporting person undertakes to provide the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within.
F5	Grant of stock options. The stock options vest over four years, assuming continuous service on each vesting date, as follows: 25% vest on the first anniversary of the date of grant, February 16, 2024; and the remaining 75% vest in 36 approximately equal monthly installments, with the options becoming fully vested on February 16, 2027.
