The Shares purchased by HCPF were purchased with working capital (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market purchases. The aggregate purchase price of the 2,309,775 Shares beneficially owned by HCPF was approximately $3,602,602 including brokerage commissions.

The Reporting Persons purchased the Shares based on the Reporting Persons' belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. 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. The Reporting Persons and their representatives have, from time to time, engaged in, and expect to continue to engage in, discussions with members of management of the Issuer and the board of directors of the Issuer (the "Board"), other current or prospective shareholders, industry analysts, and other third parties regarding a variety of matters relating to the Issuer, which may include, among other things, the Issuer's business, management, capital structure and allocation, corporate governance, Board composition and strategic direction, and may take other steps seeking to bring about changes to increase shareholder value as well as pursue other plans or proposals that relate to or could result in any of the matters set forth in clauses (a)-(j) of Item 4 of Schedule 13D. Relatedly, HCPF submitted a shareholder proposal (the "Proposal") and supporting statement for inclusion in the Issuer's 2026 proxy statement and for consideration at the Issuer's 2026 Annual Meeting of Stockholders. The Proposal requests that the Board take all necessary steps (including any amendments to the certificate of incorporation and/or bylaws), in compliance with applicable law and subject to shareholder approval, to eliminate the classification of the Board so that all directors are elected at or after the 2026 Annual Meeting of Shareholders be elected annually. Copies of the Proposal and supporting statement may be found on the SEC's website at: https://www.sec.gov/Archives/edgar/data/1369290/000119312526223981/myo-20260514.htm#proposal_seven.
