The aggregate amount of shares of common stock, $0.01 par value per share, of the Issuer (the “Common Stock”) that may be deemed beneficially owned by Haldor Topsøe Holding A/S (“HTH”) is comprised of (i) 10,400,564 shares of Common Stock held directly by HTH and (ii) 2,269,838 shares of non-voting common stock of the Issuer (the “Non-Voting Common Stock”) held directly by HTH. Jakob Haldor Topsøe, Christina Teng Topsøe, Anne Haugwitz-Hardenberg-Reventlow and Emil Øigaard, members of the board of directors of HTH, may be deemed to share voting and investment power with respect to the shares reported herein and disclaim beneficial ownership of such shares, except to the extent of his or her pecuniary interest therein, if any. Pursuant to the Issuer’s amended and restated certificate of incorporation, as amended, each holder of shares of Non-Voting Common Stock shall have the right to convert each share of Non-Voting Common Stock held by such holder into one share of Common Stock at such holder’s election by providing written notice to the Issuer; provided, however, that such shares of Non-Voting Common Stock may only be converted into shares of Common Stock during such time or times as immediately prior to or as a result of such conversion would not result in the holder thereof beneficially owning, in excess of the Beneficial Ownership Limitation. The “Beneficial Ownership Limitation” means initially 4.99% of the Common Stock. Any holder of Non-Voting Common Stock may increase the Beneficial Ownership Limitation with respect to such holder upon 61 days’ prior written notice to the Issuer and may decrease the Beneficial Ownership Limitation at any time upon providing written notice of such election to the Issuer. Because the percentage of shares of Common Stock held directly by HTH currently exceeds 4.99%, the conversion of the shares of Non-Voting Common Stock held by HTH is limited in its entirety by the Beneficial Ownership Limitation at this time.

Percentage calculated based on (i) 25,482,636 shares of Common Stock outstanding as reported in the Issuer’s final prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on December 9, 2020 in connection with the Issuer’s underwritten offering, plus (ii) the 2,269,838 shares of Non-Voting Common Stock held by HTH that may be converted into shares of Common Stock at the election of HTH.
