Purpose of transaction

The Reporting Persons purchased the Common Stock reported hereunder for investment purposes but the Reporting Persons and certain of their affiliates have continuously evaluated the Issuer's businesses, results of operations, and prospects. Agreement and Plan of Merger On September 28, 2026, the Issuer entered into an Agreement and Plan of Merger (the "Merger Agreement") with Transom Signal AcquireCo, LLC, a Delaware limited liability company ("Parent"), and Transom Signal MergerSub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent ("Merger Sub"). Parent and Merger Sub are affiliates of and commonly controlled with the Reporting Persons. Terms used but not defined within this description of the Merger Agreement shall have the meanings set forth in the Merger Agreement. The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, Parent will cause Merger Sub to commence a tender offer (the "Offer") no later than fifteen (15) business days after the date of the Merger Agreement, to purchase any and all of the shares of Common Stock, other than certain exceptions, for (i) $8.00 per share of Common Stock, plus (ii) one non-transferable contingent value right per share of Common Stock, which represents a right to receive up to $3.00, upon the achievement of specified milestones. The Offer will remain open for twenty (20) business days, subject to extension under certain circumstances. The source of funds required to consummate such Offer is expected to come from committed capital provided by an affiliate of Parent and Merger Sub and debt incurred by Parent, Merger Sub or one of their affiliates. Following the consummation of the Offer, and subject to the satisfaction or waiver, to the extent permitted under applicable legal requirements, of certain conditions set forth in the Merger Agreement, Parent, Merger Sub and the Issuer will, in accordance with Section 251(h) of the General Corporation Law of the State of Delaware, without a vote of the stockholders of the Issuer, effect a merger of Merger Sub with and into the Issuer (the "Merger" and, together with the Offer, the "Transactions"), with the Issuer continuing as the surviving corporation and as a wholly owned subsidiary of Parent. The obligations of Merger Sub to accept for purchase, and pay for, shares of Common Stock validly tendered (and not validly withdrawn) pursuant to the Offer are subject to satisfaction or waiver of certain customary conditions, including that there have been validly tendered and not validly withdrawn shares of Common Stock that would result in beneficial ownership by Parent and its Affiliates of more than 50% of the Common Stock outstanding at the time of expiration of the Offer. If the Offer and the Merger are consummated, the Common Stock will cease to be registered under Section 12 of the Exchange Act, and the Issuer will become privately held as a subsidiary of Parent. The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is filed as Exhibit 99.1 to this Schedule 13D and is incorporated herein by reference. Tender and Support Agreement Simultaneously with the execution of the Merger Agreement, Veradace Partners, LP ("Veradace") entered into a Tender and Support Agreement (the "Tender and Support Agreement") with Parent and Merger Sub. Veradace beneficially owns approximately 15.8% of the outstanding shares of Common Stock of the Issuer. Terms used but not defined within this description of the Tender and Support Agreement shall have the meanings set forth in the Tender and Support Agreement. Pursuant to the Tender and Support Agreement, Veradace has agreed, among other things, to (1) validly tender its Subject Shares (as defined in the Tender and Support Agreement) into the Offer and not withdraw such shares, (2) vote its Subject Shares against any competing takeover proposal and other actions that would impede the Transactions, and (3) not transfer its Subject Shares, in each case subject to certain exceptions. The Tender and Support Agreement also contains customary non-solicitation and other obligations and terminates automatically upon the valid termination of the Merger Agreement or certain other events described therein. The foregoing description of the Tender and Support Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Tender and Support Agreement, a copy of which is attached hereto as Exhibit 99.2 and is incorporated herein by reference. Tender, Support and Reinvestment Agreement Concurrently with the execution of the Merger Agreement, Gary M. Lauder and certain affiliated stockholders (the "Lauder Stockholders") of the Issuer entered into a tender, support and reinvestment agreement (the "Tender, Support and Reinvestment Agreement") with Parent, Merger Sub and certain of Parent's affiliates. These stockholders beneficially own approximately 17.0% of the outstanding shares of Common Stock of the Issuer. Terms used but not defined within this description of the Tender, Support and Reinvestment Agreement shall have the meanings set forth in the Tender, Support and Reinvestment Agreement. Pursuant to the Tender, Support and Reinvestment Agreement, the Lauder Stockholders have agreed, among other things, and subject to the terms and conditions of the Tender, Support and Reinvestment Agreement, to (1) validly tender their Subject Shares (as defined in the Tender, Support and Reinvestment Agreement) into the Offer and not withdraw such shares, (2) vote their Subject Shares against any competing takeover proposal and other actions that would impede the Transactions, (3) not transfer their Subject Shares, in each case subject to certain exceptions, and (4) following the effective time of the Merger, purchase equity interests of Transom Signal HoldCo, Inc., a Delaware corporation, in exchange for an aggregate amount of cash calculated to result in the applicable stockholders holding, in the aggregate, an agreed percentage of the equity interests of Transom Signal TopCo, LP, a Delaware limited partnership ("Topco"), and immediately thereafter contribute such equity interests to Topco in exchange for equity interests of equivalent value in Topco. The Tender, Support and Reinvestment Agreement also contains customary non-solicitation and other obligations and terminates automatically upon the valid termination of the Merger Agreement or certain other events described therein. The foregoing description of the Tender, Support and Reinvestment Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Tender, Support and Reinvestment Agreement, a copy of which is attached hereto as Exhibit 99.3 and is incorporated herein by reference. Except for the foregoing, none of the Reporting Persons has any plans or proposals which relate to, or would result in, any of the matters referred to in paragraphs (a) through (j) of Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, formulate other purposes, plans or proposals regarding the Issuer, or any other actions that could involve one or more of the types of transactions or have one or more of the results described in paragraphs (a) through (j) of Item 4 of Schedule 13D.

Percentage of class

The information set forth in rows (11) and (13) of the cover pages to this Schedule 13D is incorporated by reference into this Item 5. The reported securities are directly held by Transom Public Fund, and in the aggregate represent approximately 1.16% of the outstanding Common Stock based on 13,240,512 shares of Common Stock outstanding as of September 24, 2026, as reported in Section 4.7(b) of the Agreement and Plan of Merger, dated as of September 28, 2026, filed on September 29, 2026 as Exhibit 2.1 to the Issuer's Current Report on Form 8-K. In addition, as a result of the matters described in Item 4 above, the Reporting Persons and certain stockholders of the Issuer, including the Lauder Stockholders and Veradace, may collectively be deemed to constitute a "group" within the meaning of Rule 13d-5(b) under the Exchange Act. Based upon information provided to the Reporting Persons by the Lauder Stockholders and Veradace, such group would collectively beneficially own 4,498,634 shares of Common Stock, which represents approximately 34.0% of the Issuer's outstanding shares of Common Stock. The Reporting Persons disclaim beneficial ownership of shares of Common Stock beneficially owned by the Lauder Stockholders and Veradace, which are not included in the securities reported on this Schedule 13D. In this regard, Gary M. Lauder and his applicable affiliates and Veradace Capital and its applicable affiliates are each filing a separate Schedule 13D (including, in the case of Veradace, an amendment to its Schedule 13D) that reports each of their own holdings of Common Stock. 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 reported securities, or a member of a Section 13(d) group with respect to the Issuer's securities, for purposes of Section 13(d) of the Exchange Act, or for any other purpose.
