Explanation of Responses:

1. Represents common units ("Common Units") of Lumexa Imaging Equity Holdco, LLC ("Holdings LLC") held by the Reporting Person. Each nine Common Units represent the right to acquire one share of the Issuer's common stock ("Common Stock") held by Holdings LLC. After the closing of the Issuer's initial public offering ("IPO"), Holdings LLC may distribute all or a portion of the shares of the Common Stock it holds to its remaining equity holders on a pro rata basis, not earlier than the expiration of a 180-day lock-up period (a "Distribution"). Accordingly, the shares of Common Stock reported on this row represent shares of Common Stock that the Reporting Person is entitled to receive in connection with a Distribution in exchange for their Common Units.

2. Represents Common Units of Holdings LLC held by Charlotte Radiology Investors, LLC. Each nine Common Units represent the right to acquire one share of the Common Stock held by Holdings LLC. The shares of Common Stock reported on this row represent the Reporting Person's indirect pro-rata interest in the shares of Common Stock held by Charlotte Radiology Investors, LLC which will be received by Charlotte Radiology Investors, LLC in connection with a Distribution in exchange for the Common Units. The Reporting Person disclaims beneficial ownership of the shares of Common Stock held by Charlotte Radiology Investors, LLC.

Remarks:

Exhibit List: Exhibit 24 - Power of Attorney. In addition to the securities reported herein, the Reporting Person also holds rollover incentive units ("Rollover Incentive Units") of Holdings LLC. Shares of Common Stock will be issued as replacement awards under the Issuer's 2025 Equity and Incentive Plan (the "Distributed Shares") in settlement of the Rollover Incentive Units that will remain outstanding at the time of a Distribution. The number of Distributed Shares to be issued as replacement awards for the Rollover Incentive Units will be based on the value of those units at the time of a Distribution, as determined by the board of managers of Holdings LLC and after taking into account any distribution threshold applicable to such Rollover Incentive Units. The Rollover Incentive Units may become eligible to receive additional Distributed Shares upon a Distribution, with certain of the Rollover Incentive Unit Holders receiving additional Distributed Shares if the trading price of the Common Stock exceeds $7.02 per share at the time of a Distribution and all of the Rollover Incentive Unit Holders receiving additional Distributed Shares if the trading price of the Common Stock exceeds $20.07 per share at the time of a Distribution. Because the conversion ratio of the Rollover Incentive Units into the shares of Common Stock has not fixed as of the time of this filing, such Rollover Incentive Units are not "derivative securities," as such term is defined in Rule 16a-1(c) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and are not reportable under Section 16 of the Exchange Act. Accordingly, the Rollover Incentive Units held by the Reporting Person are excluded from this filing. This Form 3 is being filed late due to unanticipated delays in receiving the Reporting Person's EDGAR codes, which delays we understand were due to the high volume of applications at the time.
