Item 4.

Ownership.

Provide the following information regarding the aggregate number and percentage of the class of securities of the Issuer identified in Item 1.

(a)           Amount Beneficially Owned:

Reference to “beneficial ownership” of securities for purposes of this statement (this “Statement”) shall be understood to refer to beneficial ownership as that term is defined in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

As of December 31, 2023, the Reporting Persons may be deemed to beneficially own an aggregate 1,077,080 shares of the Issuer’s Voting Common Stock.

As of December 31, 2023, the 2017 Partnership was the direct beneficial owner of 641,848 of the shares of the Voting Common Stock described in the preceding paragraph. 2017 GP is the general partner of the 2017 Partnership, and 2017 LLC is the general partner of 2017 GP. As such, 2017 GP and 2017 LLC may each be deemed to indirectly beneficially own the securities that are directly beneficially owned by the 2017 Partnership.

As of December 31, 2023, the 2019 Partnership was the direct beneficial owner of 435,232 shares of the Voting Common Stock described in the second paragraph of this Item 4(a). 2019 GP is the general partner of the 2019 Partnership, and 2019 LLC is the general partner of 2019 GP. As such, 2019 GP and 2019 LLC may each be deemed to indirectly beneficially own the securities that are directly beneficially owned by the 2019 Partnership.

Additionally, as of December 31, 2023: (i) Alphabet Holdings was the sole managing member of both 2017 LLC and 2019 LLC; (ii) XXVI was the sole managing member of Alphabet Holdings; and (iii) Parent was the controlling stockholder of XXVI. As such, each of Alphabet Holdings, XXVI, and Parent may be deemed to indirectly beneficially own all of the Issuer’s securities that are directly or indirectly beneficially owned by each of the other Reporting Persons, comprising an aggregate total of 1,077,080 shares of the Issuer’s Voting Common Stock.

Notwithstanding, the filing of this Statement shall not be construed as an admission that: (i) the 2017 Partnership, 2017 GP and 2017 LLC (collectively, the “2017 Affiliates”), on the one hand, or (ii) the 2019 Partnership, 2019 GP and 2019 LLC (collectively, the “2019 Affiliates”), on the other hand, is or has been, for purposes of Sections 13(d) or 13(g) of the Exchange Act, the direct or indirect beneficial owner of any of the Issuer’s securities reported herein as beneficially owned by the other. The 2017 Affiliates and the 2019 Affiliates (each, an “Affiliate Group”) expressly disclaim beneficial ownership of the securities beneficially owned by the other Affiliate Group.

(b)           Percent of Class:
