| Item 4. | Purpose of Transaction | |
The Reporting Persons acquired the Shares solely for investment purposes, based on the belief that the Issuer is currently successfully executing its strategic plan, is at a financial inflection point and remains undervalued relative to its long-term intrinsic valuation. The Reporting Persons have had constructive conversations with the Issuer during which, among other things, the Reporting Persons have made clear their strong support for, and appreciation of the efforts of, the Issuer's management team and the Board of Directors (the "Board"). The Reporting Persons view the Issuer as a compelling long duration investment opportunity and have strong confidence in the Issuer's management team's articulated strategy, operational discipline, capital allocation approach and long-term vision for the business. The Reporting Persons also believe that this investment reflects a conviction in the executive team's short- and long-term ability to continue execution of the Issuer's current strategic plan, as demonstrated by several key factors: Accelerated Profitability: The Issuer's September 2025 strategic realignment and clear guidance toward the Issuer achieving positive Adjusted EBITDA and generating free cash flow in fiscal year 2026 and beyond. Operational Discipline: A belief that the Issuer has demonstrated a track record and consistent approach of disciplined expense management and deliverance of ongoing operating efficiencies. Stockholder Focus: A belief that the Issuer has demonstrated commitment to stockholder-friendly capital returns, including, based on evaluation of publicly available materials provided by the Issuer, over $33 million in historical share repurchases and the recently authorized $12 million share repurchase program. Red Apple Group is one of the top private companies in North America, as reported by Forbes. Founded in 1968, Red Apple Group is a long-term investor that considers the Issuer to be one of the most distinctive and strategically positioned digital marketplaces globally. Red Apple Group is fully supportive of the Issuer's current management team, its long-term strategy, and balanced approach to capital allocation of reinvesting for organic growth, evaluation of current and future inorganic growth opportunities and returning capital to stockholders. Red Apple Group, and the other Reporting Persons, expect to continue to engage with members of the Issuer's management team and the Board, as the Reporting Persons and the Issuer deem appropriate, regarding the Issuer's business, performance and long-term opportunities. The Reporting Persons expect that these communications will be constructive and supportive of the Board and the Issuer's management team's current operational and strategic vision for the Issuer. Red Apple Group, and the other Reporting Persons, look forward to supporting the management team and being a positive, long-term partner as the Issuer's management team continues implementing its roadmap for customers, partners, employees and stockholders. No Reporting Person has any present intention to seek control of or to influence the control of the Issuer or any other plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D, except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable. | ||
