Explanation of Responses:

1. Each Restricted Stock Unit ("RSU") represents a contingent right to receive, at settlement, one share of Common Stock. This transaction represents the settlement of RSUs in shares of Common Stock on their scheduled vesting date.

2. 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 RSUs. The sale is mandated by the issuer's election to require 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.

3. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $8.98 to $9.69, inclusive. The reporting person undertakes to provide to 908 Devices Inc., any security holder of 908 Devices Inc., or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth in this footnote.

4. Represents sales effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person.

5. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $10.00 to $10.19, inclusive. The reporting person undertakes to provide to 908 Devices Inc., any security holder of 908 Devices Inc., or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth in this footnote.

6. The 5,027 RSUs vested on February 1, 2023, with the remaining 15,082 RSUs vesting in three substantially equal annual installments at the three anniversary dates following February 1, 2023, subject to the reporting person's continued service through the applicable vesting date.
