### Footnotes:

(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 incentive units ("Incentive Units") of Holdings LLC held by the Reporting Person. At the closing of the Issuer's IPO, these Incentive Units will be converted into shares of 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 3]

(3) [continued from footnote 2] The time-based vesting schedule applicable to the replacement restricted stock awards will replicate 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 will be 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.

(4) Includes 11,876 shares of Common Stock subject to performance-based vesting conditions.

(5) The shares of Common Stock subject to the stock option are fully vested.

(6) The shares of Common Stock subject to the stock option vest annually in five substantially equal installments from the vesting commencement date of February 8, 2023, subject to the Reporting Person's continued service with the Issuer.

(7) Approximately 64.1% of the shares of Common Stock subject to the stock option have vested, and the remaining shares of Common Stock subject to the stock option 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.

**Remarks:**
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.
