Explanation of Responses:

( 1 )Represents incentive units ("Incentive Units") of Lumexa Imaging Equity Holdco, LLC ("Holdings LLC") held by the Reporting Person. At the closing of the Issuer's initial public offering ("IPO"), these Incentive Units were converted into shares of the Issuer's common stock ("Common Stock") based on the intrinsic value of the awards at the time of the Issuer's IPO, as determined by the board of managers of Holdings LLC, with any shares of Common Stock issued in replacement of unvested Incentive Units to be delivered as restricted stock awards, which remain subject to time-based and performance-based vesting conditions, as applicable. [continues in footnote 2] ( 2 )[continued from footnote 1] The time-based vesting schedule applicable to the replacement restricted stock awards replicates the original time-based vesting schedule applicable to the time-based Incentive Units prior to the closing of the Issuer's IPO, while the performance-based vesting conditions are tied to stock price triggers intended to replicate the performance-based vesting conditions applicable to the performance-based Incentive Units prior to the closing of the Issuer's IPO. ( 3 )Includes 11,876 shares of Common Stock that will vest upon the attainment of a prescribed stock price target of $24.97 per share, which target is measured based on the volume weighted average closing price per share of Common Stock over any consecutive sixty (60) trading day period, with the measurement period commencing on the first business day immediately following the expiration of the 180-day lock-up period, subject to the Reporting Person's continued service with the Issuer. ( 4 )Represents restricted stock units ("RSUs"), each one of which represents the contingent right to receive one share of Common Stock. The RSUs will vest in full on December 12, 2026, subject to the Reporting Person's continued service with the Issuer.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
