Explanatory Note

This Amendment No. 2 to Schedule 13D (this “Amendment”) amends and supplements the Schedule 13D of ASCN Investments Ltd. and Ari de Sá Cavalcante Neto (together, the “Reporting Persons”, and each, a “Reporting Person”) initially filed with the Securities and Exchange Commission on December 2, 2022, as amended by Amendment No. 1 filed on January 11, 2023 (as so amended, the “Schedule 13D”), with respect to the Class A common shares, par value $0.00005 per share (the “Class A Common Shares”), of Arco Platform Limited, a Cayman Islands exempted company incorporated with limited liability (the “Issuer”). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Schedule 13D.

The Schedule 13D incorrectly stated the number of Class A Common Shares reported as beneficially owned by the Reporting Persons. This Amendment is filed to correct such error and the corresponding percentages. Except as specifically provided herein, this Amendment does not modify or amend any of the information previously reported in the Schedule 13D.

Item 5 is hereby amended and supplemented as follows:

By virtue of submitting the Proposal, the Reporting Persons may be deemed to be members of a “group” with General Atlantic, Dragoneer Investment Group, LLC and Marc Stad (together, “Dragoneer”), and Oto Brasil de Sá Cavalcante that own Class A Common Shares and Class B Common Shares pursuant to Section 13(d) of the Exchange Act as a result of jointly submitting the proposal. However, each Reporting Person expressly disclaims beneficial ownership of the Class A Common Shares beneficially owned by any other reporting person(s), General Atlantic, Dragoneer or Mr. Brasil de Sá Cavalcante. Neither the filing of this Amendment nor any of its contents shall be deemed to constitute an admission that any of the Reporting Persons beneficially owns any Class A Common Shares or Class B Common Shares of the Issuer that are beneficially owned by any other reporting person(s), General Atlantic, Dragoneer or Mr. Brasil de Sá Cavalcante. The Reporting Persons are only responsible for the information contained in this Amendment and assume no responsibility for information contained in any other Amendment filed by any other reporting person(s), General Atlantic, Dragoneer or Mr. Brasil de Sá Cavalcante.

Based on Amendment No. 1 to Schedule 13D filed by Oto Brasil de Sá Cavalcante and the other reporting person therein with the Securities and Exchange Commission on January 11, 2023, Mr. de Sá Cavalcante and the other reporting person beneficially own 19,103,363 Class B Common Shares, which represents approximately 33.1% of the Class A Common Shares outstanding (based on (i) 38,525,716 Class A Common Shares outstanding (based on information provided by the Issuer as of February 2, 2023), and (ii) 19,103,363 Class A Common Shares issuable upon conversion of the Class B Common Shares) (as calculated in accordance with Rule 13d-3(d)(1)(i)), approximately 69.7% of the total number of Class B Common Shares outstanding, and voting power of approximately 61.1% (the percentage of total voting power represents voting power with respect to all Class A Common Shares and Class B Common Shares, as a single class).

Based on Amendment No. 3 to Schedule 13D filed by General Atlantic and the other reporting persons therein with the Securities and Exchange Commission on January 11, 2023, General Atlantic and the other reporting persons beneficially own 5,827,504 Class A Common Shares, which includes (a) 4,103,366 Class A Common Shares, and (b) 1,724,138 Class A Common Shares issuable upon conversion of all the Company’s Senior Convertible Notes due 2028 (the “2028 Convertible Notes”) held by General Atlantic and the other reporting persons. Based on (i) 38,525,716 Class A Common Shares outstanding (based on information provided by the Issuer as of February 2, 2023), and (ii) 1,724,138 Class A Common Shares issuable upon conversion of all the 2028 Convertible Notes held by General Atlantic and the other reporting persons, General Atlantic and the other

reporting persons beneficially own approximately 14.5% of the outstanding Class A Common Shares (as calculated in accordance with Rule 13d-3(d)(1)(i)).

Based on Amendment No. 2 to Schedule 13D filed by Dragoneer Adviser and Marc Stad with the Securities and Exchange Commission on January 11, 2023, Dragoneer beneficially owns 5,013,675 Class A Common Shares, which includes (a) 1,565,395 Class A Common Shares, and (b) 3,448,280 Class A Common Shares issuable upon conversion of all the 2028 Convertible Notes held by Dragoneer. Based on (i) 38,525,716 Class A Common Shares outstanding (based on information provided by the Issuer as of February 2, 2023), and (ii) 3,448,280 Class A Common Shares issuable upon conversion of all the 2028 Convertible Notes held by Dragoneer, Dragoneer beneficially owns approximately 11.9% of the outstanding Class A Common Shares (as calculated in accordance with Rule 13d-3(d)(1)(i)).

Accordingly, in the aggregate, the Reporting Persons, General Atlantic, Dragoneer and Oto Brasil de Sá Cavalcante may be deemed to beneficially own 38,639,376 Class A Common Shares, comprised of an aggregate of 6,066,110 Class A Common Shares, 5,172,418 Class A Common Shares issuable upon conversion of the 2028 Convertible Notes and 27,400,848 issuable upon conversion of Class B Common Shares, which, as calculated in accordance with Rule 13d-3(d)(1)(i), represents approximately 54.3% of the total number of Class A Common Shares based on (i) 38,525,716 Class A Common Shares outstanding (based on information provided by the Issuer as of February 2, 2023), and (ii) an aggregate of 32,573,266 Class A Common Shares issuable upon conversion of all the 2028 Convertible Notes and all the Class B Common Shares beneficially owned by the Reporting Persons, General Atlantic, Dragoneer and Oto Brasil de Sá Cavalcante.

The information disclosed under Item 5(a) above is hereby incorporated by reference into this Item 5(b).
