Lampropoulos resigned as Chief Executive Officer and President of Merit and transitioned his employment to the role of Executive Chairman and (ii) Merit's Board of Directors appointed Martha G. Aronson as Merit's new Chief Executive Officer and President. The Board of Directors also voted to expand the number of directors on Merit’s Board of Directors from ten to eleven and to appoint Ms. Aronson as a director. In connection with Ms. Aronson's appointment, the Company granted to Ms. Aronson (x) restricted stock units representing 19,594 shares of Common Stock with a three-year vesting period and (y) Performance Stock Units representing up to 73,478 shares of Common Stock, subject to Merit’s financial and market performance relative to specified targets, which will be released at the end of the performance period. On October 15, 2025, we entered into an Asset Purchase Agreement (the “Pentax Agreement”) with Pentax of America, Inc., a subsidiary of PENTAX® Medical, Inc., to acquire the C2 CryoBalloon™ device and related technology for total cash consideration of $22 million (collectively, the “Pentax Acquisition”). The closing of the proposed transaction is expected to occur during the fourth quarter of 2025, subject to the satisfaction or waiver (in accordance with the provisions of the Pentax Agreement) of certain customary closing conditions. The total purchase consideration consists of a $19 million cash payment at closing and potential contingent payments of up to $3 million payable upon meeting certain milestones. We are currently evaluating the accounting treatment of the Pentax Acquisition, as well as performing the valuation of the assets acquired and the related purchase price allocation.
