MRNA 0001760669 Hoge Stephen C/O MODERNA, INC. 200 TECHNOLOGY SQUARE CAMBRIDGE MA 02139 1 President Common Stock 2020-03-13 4 S 0 1110 22.43 D 2046733 D This sale was effected pursuant to a Rule 10b5-1 trading plan adopted on December 27, 2018. The Form 4 filed on March 16, 2020 by the reporting person inadvertently understated the number of shares sold by the reporting person by 10 shares. Such 10 shares were also inadvertently included in Column 5 of Forms 4 filed by the reporting person after such date. This Form 4 corrects such error by increasing the number of shares sold in this transaction, and decreasing the total amount of securities beneficially owned by the reporting person immediately after this transaction, by such 10 shares. The price reported in Column 4 is a weighted average price. The shares were sold in multiple transactions at prices ranging from $21.95 to $22.90. Full information regarding the number of shares sold at each separate price can be furnished to the SEC staff upon request. /s/ Lori Henderson, as Attorney-in-Fact 2020-07-15
