EXPLANATORY NOTE

This Amendment No. 3 to Schedule 13D (this “Amendment No. 3”) is being filed by the Reporting Persons (as defined below) in connection with a purchase by CCM Prosper L.P. (“CCM Prosper”), a limited partnership incorporated under the laws of the Cayman Islands, Tianyu Ruikong Limited (“Tianyu”), a company incorporated under the laws of the British Virgin Islands, and Masterclass Holdings Limited (“Masterclass”), an exempted company incorporated with limited liability under the laws of the Cayman Islands, of an aggregate of 78,476,629 Class A ordinary shares, par value US$0.000002 per share (the “Class A Ordinary Shares”) of Luckin Coffee Inc., a Cayman Islands exempted company (the “Issuer”), from Camel ZQ Limited (“Camel ZQ”), an exempted company incorporated with limited liability under the laws of the Cayman Islands.

Item 1. Security and Issuer.

This Amendment No.3 amends and supplements the prior statement on Schedule 13D as filed on December 9, 2021 (the “Original 13D”), Amendment No. 1 to Schedule 13D as filed on January 27, 2022 (the “Amendment No. 1”) and Amendment No. 2 to Schedule 13D as filed on March 11, 2022 (the “Amendment No. 2” and as amended and supplemented by this Amendment No. 3, this “Schedule 13D”), and relates to the beneficial ownership of the Class A Ordinary Shares of the Issuer whose principal executive offices is located at 28th Floor, Building T3, Haixi Jingu Plaza, 1-3 Taibei Road, Siming District, Xiamen City, Fujian, People’s Republic of China, 361008.

In addition to the Class A Ordinary Shares, this Schedule 13D discloses interests with respect to the Class B ordinary shares, par value US$0.000002 per share, of the Issuer (the “Class B Ordinary Shares”) and the senior convertible preferred shares, par value US$0.000002 per share, of the Issuer (the “Preferred Shares”).

The rights of the holders of the Class A Ordinary Shares and Class B Ordinary Shares are substantially identical, except with respect to voting and conversion rights. Each Class A Ordinary Share is entitled to one vote and each Class B Ordinary Share is entitled to ten votes and is convertible into one Class A Ordinary Share at any time by the holder thereof. Each Preferred Share is entitled to a number of votes equal to the number of Class A Ordinary Shares into which such Preferred Share is convertible. Each Preferred Share shall be convertible, at any time at the option of the holder thereof and at such holder’s sole discretion, into that number of Class A Ordinary Shares (or an equivalent number of ADSs) determined by dividing (i) the sum of the original issue price plus any declared but unpaid dividends on such Preferred Share, by (ii) the conversion price in effect at time of the conversion, which shall initially be the original issue price of US$0.8125 per Preferred Share and is subject to adjustment from time to time. In addition, certain reserved matters are subject to prior written consent of the holders of a majority of the outstanding Preferred Shares and holders of Preferred Shares are entitled to certain downside protection from regulatory events.

The Issuer’s American depositary shares (the “ADSs”), each representing eight Class A Ordinary Shares, were previously listed on NASDAQ and traded under the symbol “LK” prior to their delisting on July 1, 2020, and are currently trading on the OTC Pink Sheets under the symbol (OTCPK: LKNCY).

Item 5 is hereby amended and restated in its entirety, as follows:

(a) - (b) The responses of each Reporting Person to Rows (7) through (13), including the footnotes thereto, of the cover pages of this Schedule 13D and Item 2 above are hereby incorporated by reference in this Item 5.

The reported securities are directly held as follows: (a) Lucky Cup Holdings Limited (“Lucky Cup”), an exempted company incorporated with limited liability under the laws of the Cayman Islands, holds 136,172,000 Class B Ordinary Shares, convertible into 136,172,000 Class A Ordinary Shares; (b) Fortunate Cup Holdings Limited (“Fortunate Cup”), an exempted company incorporated with limited liability under the laws of the Cayman Islands, holds 8,606,500 Class B Ordinary Shares, convertible into 8,606,500 Class A Ordinary Shares; (c) Cannonball Limited (“Cannonball”), an exempted company incorporated with limited liability under the laws of the Cayman Islands, holds 295,384,615 Preferred Shares, convertible into 295,384,615 Class A Ordinary Shares (subject to certain anti-dilution adjustments); (d) Camel ZQ holds 77,199,046 Class A Ordinary Shares (including 20,625,056 Class A Ordinary Shares in the form of 2,578,132 ADSs); (e) Cameleer L.P. (“Cameleer”), a limited partnership incorporated under the laws of the Cayman Islands, holds 125,405,404 Class A Ordinary Shares; (f) Cameleer II L.P. (“Cameleer II”), a limited partnership incorporated under the laws of the Cayman Islands, holds 102,344,669 Class A Ordinary Shares; (g) CCM Prosper holds 32,313,906 Class A Ordinary Shares; (h) Masterclass holds 32,313,906 Class A Ordinary Shares; and (i) Tianyu holds 13,848,817 Class A Ordinary Shares.

Centurium Capital Partners 2018, L.P., a limited partnership incorporated under the laws of the Cayman Islands (“Centurium Fund I”), is the sole shareholder of Lucky Cup and Fortunate Cup. Mr. Li has sole voting and investment discretion with respect to Tianyu. Centurium Capital Partners II, L.P., a limited partnership incorporated under the laws of the Cayman Islands (“USD Fund II”), is the sole shareholder of Masterclass. Cannonball is wholly owned by (i) Centurium Fund I, (ii) CCM Lucky, L.P., a limited partnership incorporated under the laws of the Cayman Islands (“CCM Lucky”) and (iii) CCM CB II, L.P., a limited partnership incorporated under the laws of the Cayman Islands (“CCM CB II”, and together with CCM Lucky, Centurium Fund I, USD Fund II, Cameleer, Cameleer II and CCM Prosper, the “Funds”).

Centurium holds interests in the general partners of certain private equity funds, including the Funds, that hold interests in Lucky Cup, Fortunate Cup, Cannonball and Masterclass. Mr. Li is the sole shareholder and director of Centurium Holdings (BVI) Ltd., which is the sole shareholder of Centurium. All voting power in Camel ZQ is held by an entity ultimately controlled by Mr. Li.

Accordingly, each Reporting Person may be deemed to share voting and dispositive power with respect to, and therefore beneficially own, the (i) 136,172,000 Class B Ordinary Shares held by Lucky Cup, (ii) 8,606,500 Class B Ordinary Shares held by Fortunate Cup, (iii) 295,384,615 Preferred Shares held by Cannonball, (iv) 77,199,046 Class A Ordinary Shares held by Camel ZQ (including 20,625,056 Class A Ordinary Shares in the form of 2,578,132 ADSs), (v) 125,405,404 Class A Ordinary Shares held by Cameleer, (vi) 102,344,669 Class A Ordinary Shares held by Cameleer II, (vii) 32,313,906 Class A Ordinary Shares held by CCM Prosper, (viii) 32,313,906 Class A Ordinary Shares held by Masterclass, and (ix) 13,848,817 Class A Ordinary Shares held by Tianyu.

In light of the fact that the voting and investment decisions with respect to the shares of the Issuer held by the Record Holders are made solely by the Reporting Persons, each of Lucky Cup, Fortunate Cup, Cannonball, Camel ZQ, Cameleer, Cameleer II, Centurium Fund I, CCM Lucky and CCM CB II disclaim beneficial ownership of the reported securities (including any shares of the Issuer directly held by any of the foregoing) and accordingly, have ceased reporting with respect to the reported securities.

(c) Except as disclosed in this Schedule 13D, none of the Reporting Persons has effected any transaction in the Class A Ordinary Shares, the Class B Ordinary Shares or the Preferred Shares during the past 60 days.

(d) Except as disclosed in this Schedule 13D, to the best knowledge of the Reporting Persons, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Class A Ordinary Shares, the Class B Ordinary Shares or the Preferred Shares beneficially owned by any of the Reporting Persons.

(e) Not applicable.
