Item 3. Source and Amount of Funds or Other Consideration.

This Schedule 13D is not being made as a result of any particular acquisition or disposition of shares of Common Stock by the Reporting Persons. The descriptions of the Potential Transaction (as defined below) under Item 4 is incorporated herein by reference in its entirety.

Item 4. Purpose of Transaction.

The Reporting Persons acquired beneficial ownership of the shares of Common Stock for investment purposes, and such purposes were made in the Reporting Persons’ ordinary course of business. The Reporting Persons intend to review their respective investments on a regular basis and, as a result thereof, may, directly or through one or more affiliates, at any time or from time to time determine, either individually or as part of a group, (i) to acquire additional securities of the Issuer, through open market purchases, privately negotiated transactions, or otherwise, (ii) to dispose of all or a portion of the securities of the Issuer owned by them in the open market, in privately negotiated transactions, or otherwise, or (iii) to take any other available course of action, which could involve one or more of the types of transactions or have one or more of the results specified in paragraphs (a) through (j) of Item 4 of Schedule 13D under the Exchange Act. Any such acquisition or disposition or other transaction would be made in compliance with all applicable laws and regulations, and subject to the terms and conditions of any agreements between any Reporting Person and the Issuer.

The Reporting Persons have explored, and expect to continue to explore, either individually or as part of a group of some or all of the Reporting Persons, various potential alternatives with respect to their investments in the Issuer, including, among other things, extraordinary corporate transactions involving the Issuer, such as a merger, reorganization, consolidation or other take-private transaction that could result in the delisting and/or deregistration of the publicly traded securities of the Issuer, joint ventures, or other material changes to the Issuer’s business or capital or governance structure (any of the foregoing, a “Potential Transaction”). There can be no guarantee that the Reporting Persons will make any such proposal, and if any such proposal is made, the Reporting Persons can provide no assurances such proposal will be accepted or that they will successfully consummate any Potential Transaction. Continued exploration of any such proposal, and whether the Reporting Persons will make any such proposal and the completion of any such Potential Transaction, is subject to many factors, many of which are outside the control of the Reporting Persons, including, but not limited to, the following: terms believed by the Reporting Persons to be favorable to them; the Reporting Persons’ ongoing assessment of the Issuer’s business, prospects, and other developments concerning the Issuer and its businesses generally; changes in law and government regulations; general economic conditions; tax considerations; other investment opportunities available to the Reporting Persons; and prevailing market conditions, including the market price of the securities of Issuer.

The iSelect Reporting Persons have been engaged, and intend to continue to engage, in communications, discussions and negotiations with members of the Issuer’s management and of the board of directors of the Issuer (the “Board”), and their respective legal, financial, accounting and other advisors; potential partners and counterparties in any Potential Transaction; current or prospective stockholders of the Issuer; and other relevant parties, regarding the various alternatives that may from time to time be under consideration by the iSelect Reporting Persons and/or their affiliates.

The Argonautic Reporting Persons, S2G, Fall Line and O’Brien and Crisp have begun to engage, and intend to continue to engage, in communications, discussions and negotiations with members of the Issuer’s management and of the Board, and their respective legal, financial, accounting and other advisors; potential partners and counterparties in any Potential Transaction; current or prospective stockholders of the Issuer; and other relevant parties, regarding the various alternatives that may from time to time be under consideration by the Argonautic Reporting Persons, S2G, Fall Line and O’Brien, Crisp and/or their affiliates.

To facilitate their consideration of such matters, each of the Reporting Persons has retained, or intends to retain, consultants and advisors and enter into discussions with potential sources of capital and other third parties. Each of the Reporting Persons may exchange information with any such persons pursuant to appropriate confidentiality or similar obligations or agreements.

In addition, the Reporting Persons have begun to engage, and intend to continue to engage, on a coordinated basis, in communications, discussions and negotiations with each of the other Reporting Persons to engage in concerted actions regarding a Potential Transaction. In connection with the communications, discussions and negotiations referenced in the preceding sentence, each Reporting Person that is a party to a non-disclosure agreement or confidentiality agreement with the Issuer has, to the extent necessary, requested from the Issuer, and received, a waiver from the provisions of their respective non-disclosure agreement or confidentiality agreement that would otherwise preclude such communications, discussions and negotiations. SEC guidance provides that as a result of such communications, discussions and negotiations by the Reporting Persons with each of the other Reporting Persons regarding a Potential Transaction, (i) the Reporting Persons may be deemed to be a part of a group with each of the other Reporting Persons acting together for that common purpose, and (ii) the shares of Common Stock beneficially owned by each Reporting Person may be deemed to be beneficially owned by each of the other Reporting Persons. The iSelect Reporting Persons disclaim any beneficial ownership of the shares of Common Stock held by the other Reporting Persons (not including any iSelect Reporting Person). The Argonautic Reporting Persons disclaim any beneficial ownership of the shares of Common Stock held by the other Reporting Persons (not including any Argonautic Reporting Person). S2G disclaims any beneficial ownership of the shares of Common Stock held by the other Reporting Persons. Fall Line and O’Brien disclaim any beneficial ownership of the shares of Common Stock held by the other Reporting Persons (not including Fall Line and O’Brien). Crisp disclaims any beneficial ownership of the shares of Common Stock held by the other Reporting Persons.

Notwithstanding anything contained herein, the Reporting Persons intend to review their respective investments in the Issuer and the Issuer’s performance and market conditions periodically and to take such actions with respect to their investments as they deem appropriate in light of the circumstances existing from time to time. Accordingly, the Reporting Persons specifically reserve the right to change their intentions with respect to any or all such matters described above. Further, the Reporting Persons reserve the right to formulate other plans and/or make other proposals and take such actions with respect to their respective investments in the Issuer, including any or all of the actions set forth in paragraphs (a) through (j) of Item 4 of Schedule 13D under the Exchange Act, or acquire additional securities of the Issuer or dispose of all or a portion of the securities of the Issuer beneficially owned by them, in open market or privately negotiated transactions, or otherwise. The Reporting Persons may at any time reconsider and change their plans or proposals relating to the foregoing. In reaching any decision as to its course of action (as well as to the specific elements thereof), the Reporting Persons currently expect that they would take into consideration a variety of factors, including, but not limited to, the following: the Issuer’s business and prospects; other developments concerning the Issuer and its businesses generally; other business opportunities available to the Issuer; changes in law and government regulations; general economic conditions; tax considerations; other investment opportunities available to the Reporting Persons; and prevailing market conditions, including the market price of the securities of the Issuer.

Except as set forth in this Item 4, the Reporting Persons have no present plan or proposal that relates to or would result in any of the actions specified in paragraphs (a) through (j) of Item 4 of Schedule 13D under the Exchange Act.

Item 5. Interest in Securities of the Issuer.

(a)-(b) The information relating to the beneficial ownership of shares of Common Stock by each of the Reporting Persons set forth in Rows 7, 8, 9, 10, 11 and 13 of each of the cover pages of this Schedule 13D and the information set forth in Item 2 of this Schedule 13D is incorporated herein by reference.

By virtue of the communications, discussions and negotiations by the Reporting Persons, on a coordinated basis, with each of the other Reporting Persons to engage in concerted actions regarding a Potential Transaction, the Reporting Persons may be deemed to be members of a group with each of the other Reporting Persons acting together for that common purpose pursuant to Section 13(d) of the Exchange Act. However, (i) the iSelect Reporting Persons disclaim any beneficial ownership of the shares of Common Stock held by the other Reporting Persons (not including any iSelect Reporting Person), (ii) the Argonautic Reporting Persons disclaim any beneficial ownership of the shares of Common Stock held by the other Reporting Persons (not including any Argonautic Reporting Person), (iii) S2G disclaims any beneficial ownership of the shares of Common Stock held by the other Reporting Persons, (iv) Fall Line and O’Brien disclaim any beneficial ownership of the shares of Common Stock held by the other Reporting Persons (not including Fall Line and O’Brien), and (v) Crisp disclaims any beneficial ownership of the shares of Common Stock held by the other Reporting Persons. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that any of the Reporting Persons beneficially owns any shares of Common Stock that are beneficially owned by any other Reporting Persons, except for (i) the iSelect Reporting Persons with respect to each other, (ii) the Argonautic Reporting Persons with respect to each other, and (iii) Fall Line and O’Brien with respect to each other. The Reporting Persons are only responsible for the information contained in this Schedule 13D and assume no responsibility for information contained in any other Schedules 13D filed by any other Reporting Persons.

Assuming the Reporting Persons may be deemed to be members of a group with each of the other Reporting Persons acting together for that common purpose pursuant to Section 13(d) of the Exchange Act, and subject to the preceding paragraph, the shares of Common Stock beneficially owned by each Reporting Person may be deemed to be beneficially owned by each of the other Reporting Persons. Accordingly, in the aggregate, the Reporting Persons may be deemed to beneficially own 34,423,815 shares of Common Stock, consisting of an aggregate of (i) 34,284,927 shares of Common Stock and (ii) 138,888 shares of Common Stock issuable to certain Reporting Persons, as disclosed above, pursuant to warrants exercisable within 60 days of the date of this Schedule 13D, which, as calculated in accordance with Rule 13d-3(d)(1)(i), represents approximately 16.2% of the total number of shares of Common Stock based on (i) 212,007,581 shares outstanding as of May 7, 2024 (according to the information contained in the Issuer’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2024, filed with the SEC on May 9, 2024 and (ii) the 138,888 shares of Common Stock issuable pursuant to warrants as described above.

(c) None of the Reporting Persons has effected any transaction in shares of Common Stock during the 60 days preceding the date of this filing.

(d) To the knowledge of the Reporting Persons, no person other than the Reporting Persons has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of the Common Stock beneficially owned by any of the Reporting Persons.
