3. Reflects securities of the Issuer held directly by BCP Mozart Aggregator L.P. (together with Mozart Aggregator II LP, the "Blackstone Holders").

5. Each such Reporting Person may be deemed to beneficially own the securities of the Issuer directly held by the Blackstone Holders directly or indirectly controlled by it or him, but each (other than Mozart Aggregator II LP and BCP Mozart Aggregator L.P. to the extent of their respective direct holdings) disclaims beneficial ownership of the securities reported herein, except to the extent of such Reporting Person's pecuniary interest therein, and this filing shall not be deemed an admission that any of the Reporting Persons (other than Mozart Aggregator II LP and BCP Mozart Aggregator L.P. to the extent each directly holds securities of the Issuer) is the beneficial owner of such securities for purposes of Section 16 or any other purpose.

6. Information with respect to each of the Reporting Persons is given solely by such Reporting Person, and no Reporting Person has responsibility for the accuracy or completeness of information supplied by another Reporting Person.

7. Shares of the Issuer's Class B common stock ("Class B Common Stock") have no economic value and have one vote per share. One share of Class B Common Stock is issued for each common unit of Medline Holdings, LP ("Common Unit") held. Upon the sale of Common Units, an equivalent number of shares of Class B Common Stock were automatically cancelled.

8. On December 18, 2025, Mozart Aggregator II LP initiated in-kind distributions of shares of Class A Common Stock to one of its investors and certain affiliated entities of that investor.
