During the past five years, none of the Reporting Persons has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration

The information contained in or incorporated into Item 4 of this Schedule 13D is hereby incorporated by reference into this Item 3.

Item 4. Purpose of Transaction.

The Reporting Persons purchased the Common Stock reported hereunder for investment purposes but have continuously evaluated the Issuer’s businesses, results of operations, and prospects.

On October 6, 2024, the Issuer entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Issuer, Marlee Buyer and Marlee Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Marlee Buyer (“Merger Sub”), pursuant to which Merger Sub will be merged with and into the Issuer (the “Merger”), with the Issuer surviving the Merger. As described in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of Common Stock issued and outstanding immediately prior to the Effective Time (other than shares of Common Stock that, immediately prior to the Effective Time, are (i) held in the treasury of the Issuer or owned by the Issuer or any direct or indirect wholly owned subsidiary of the Issuer, (ii) owned by Marlee Buyer, Merger Sub or any direct or

indirect wholly owned subsidiary of Marlee Buyer or Merger Sub or (iii) held or owned by stockholders who have not voted in favor of the Merger and who have demanded, properly in writing, appraisal for such shares of Common Stock in accordance with Section 262 of the General Corporation Law of the State of Delaware) shall be converted into the right to receive an amount in cash equal to $11.10, without interest, and as of the Effective Time, all such shares will no longer be outstanding and will automatically be cancelled.

In connection with the transactions contemplated by the Merger Agreement, on October 6, 2024, certain investors affiliated with TSG Consumer Partners LLC (“TSG”) and Brown-Forman Corporation (“Brown-Forman”), in each case, in their capacity as stockholders of the Issuer, each entered into a voting and support agreement substantially consistent with the form of voting agreement attached as Exhibit 10.2 hereof (collectively, the “Voting Agreements”) with Marlee Buyer. Under the Voting Agreements, the applicable stockholders commit to vote certain of their respective shares of Common Stock, among other things, in favor of the adoption of the Merger Agreement and against any competing transaction or any other action, agreement or proposal which to its knowledge would reasonably be expected to prevent or materially impede or materially delay the consummation of the Merger or any of the other transactions contemplated by the Merger Agreement. The Voting Agreements also include certain restrictions on transfer of the shares of Common Stock held by such stockholders. The Voting Agreements terminate in certain circumstances, including in connection with the Issuer’s termination of the Merger Agreement in order to accept a superior proposal. The stockholders that signed the Voting Agreements hold shares of Common Stock representing a majority of the Issuer’s outstanding voting power as of October 4, 2023.

The foregoing descriptions of the Merger Agreement and the Voting Agreements do not purport to be complete and are each qualified in its entirety by reference to the full text of such agreement, which are filed as Exhibits 10.1 and 10.2, respectively, to this Schedule 13D and are incorporated herein by reference.

Item 5. Interest in Securities of the Issuer.

(a)-(b)

The information set forth in rows (7) through (11) of the cover pages and in Item 4 of this Schedule 13D is incorporated by reference into this Item 5. In this regard, the reported 6,377,923 shares of Common Stock are directly held by certain funds and accounts managed indirectly by Messrs. Waglay and Beck, which amount is inclusive of the 5,779,734 shares of Common Stock held by funds for which Butterfly UGP II, LLC is the ultimate general partner.

In addition, as a result of the matters described in Item 4 above, the Reporting Persons, TSG and Brown-Forman may collectively be deemed to constitute a “group” within the meaning of Rule 13d-5(b) under the Act. Based upon information provided to the Reporting Persons by TSG and Brown-Forman, TSG and Brown-Forman respectively own 61,404,559 and 31,531,532 shares of Common Stock or approximately 41.7% and 21.4% of the outstanding shares of Common Stock. Such “group” would beneficially own 99,314,014 shares of Common Stock or approximately 67.5% of the outstanding shares of Common Stock. Shares beneficially owned by the TSG and Brown-Forman are not included in the securities reflected on the cover pages, nor the subject, of this Schedule 13D and, accordingly, TSG and Brown-Forman are not included as reporting persons herein.

Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any Reporting Person is the beneficial owner of the Common Stock referred to herein for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, or for any other purpose and each of the Reporting Persons expressly disclaims beneficial ownership of such shares of Common Stock (other than such shares directly held by such Reporting Person). TSG and Brown-Forman and their affiliates have filed or are filing a separate Schedule 13D to report the Common Stock that they may be deemed to beneficially own.

(c) None of the Reporting Persons has effected any transactions in the Common Stock during the past 60 days.

(d) No person other than the Issuer is known to have the right to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, such shares of Common Stock.
