Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	This transaction occurred prior to Black Rock Coffee Bar, Inc.'s (the "Issuer") registration of a class of equity securities under Section 12 of the Securities Exchange Act of 1934, as amended, in connection with the Issuer's initial public offering, and is reported herein pursuant to Rule 16a-2(a).
(2)	Represents an award of restricted stock units ("RSUs"), each of which represents a contingent right to receive one share of Class A Common Stock. The RSUs vest in full on the earlier of the Issuer's 2026 annual meeting or the first anniversary of the closing of the Issuer's initial public offering.
(3)	LLC units ("LLC Units") represent the membership units of Black Rock Coffee Holdings, LLC ("Black Rock OpCo") and an equal number of shares of Class C common stock ("Class C Common Stock") of the Issuer. Holders may elect to have Black Rock OpCo redeem their LLC Units at any time on or following the closing of the Issuer's initial public offering for either shares of Class A common stock ("Class A Common Stock") on a one-for-one basis or, at the Issuer's election (determined solely by the Issuer's independent directors who are disinterested), a corresponding amount of cash, in either case, contributed to Black Rock OpCo by the Issuer, unless the Issuer elects, in its sole discretion (determined solely by the Issuer's independent directors who are disinterested), to effect such transaction as a direct exchange with the relevant holder. Upon any such redemption or exchange of LLC Units, the corresponding shares of Class C Common Stock will be cancelled.
(4)	The Class C Common Stock is convertible at any time, at the holder's election, into Class A Common Stock on a one-for-one basis; provided that, at the Issuer's election (determined solely by the Issuer's independent directors who are disinterested), the Issuer may effect such exchange for a cash payment equal to a volume weighted average market price of one share of Class A Common Stock for each LLC Unit so redeemed.
(5)	Each outstanding share of Class C Common Stock will automatically convert into one share of the Issuer's Class B common stock upon the earlier of (i) the ten-year anniversary of the later of the closing of the Issuer's initial public offering or the closing date of any exercise of the underwriters' option to purchase additional shares of Class A Common Stock and (ii) with respect to the Reporting Person, the date on which the aggregate number of shares of Class C Common Stock held by the Reporting Person or certain of his affiliates is less than thirty-three percent (33%) of the shares of Class C Common Stock held by the Reporting Person and certain of his affiliates as of the later of the closing of the Issuer's initial public offering or the closing date of any exercise of the underwriters' option to purchase additional shares of Class A Common Stock in the Issuer's initial public offering.
(6)	Held by Viking Cake BR, LLC ("Viking Cake") and its wholly-owned subsidiary, Viking Cake Fuel, LLC, for which the Reporting Person has voting and investment power. The Reporting Person disclaims beneficial ownership of the shares held by Viking Cake except to the extent of his pecuniary interest therein.
(7)	Represents a corresponding number of shares of Class C Common Stock issued in connection with the purchase of newly-issued LLC Units from Black Rock OpCo.
