(1)Pursuant to Rule 416(a) of the Securities Act of 1933, as amended (the “Securities Act”), this Registration Statement shall also cover any additional shares of the Registrant’s common stock, par value $0.0001 per share (the “Common Stock”) of Keros Therapeutics, Inc. (the “Registrant”), that become issuable under the Registrant’s 2020 Equity Incentive Plan (the “2020 Plan”) or 2020 Employee Stock Purchase Plan (the “2020 ESPP”) by reason of any stock dividend, stock split, recapitalization or other similar transaction that results in an increase in the number of the Registrant’s outstanding shares of Common Stock.

Pursuant to such evergreen provision, on January 1st of each year commencing in 2021 and ending on (and including) January 1, 2030, the number of shares authorized for issuance under the 2020 Plan is automatically increased by a number equal to four percent (4.0%) of the total number of shares of Common Stock outstanding on December 31st of the preceding calendar year. Notwithstanding the foregoing, the Registrant’s Board of Directors may act prior to the first day of any calendar year to provide that there will be no January 1st increase in the share reserve for such calendar year or that the increase in the share reserve for such calendar year will be a lesser number of shares of common stock than would otherwise occur pursuant to the preceding sentence.

(3)Represents shares of the Common Stock that were automatically added to the shares authorized for issuance under the 2020 ESPP on January 1, 2024 pursuant to an “evergreen” provision contained in the 2020 ESPP.

Notwithstanding the foregoing, the Registrant’s Board of Directors may act prior to the first day of any calendar year to provide that there will be no January 1st increase in the share reserve for such calendar year or that the increase in the share reserve for such calendar year will be a lesser number of shares of common stock than would otherwise occur pursuant to the preceding sentence.
