On November 2, 2021, MercadoLibre, Inc. (the “Company”), at the direction of the Audit Committee (the “Committee”) of the Board of Directors of the Company, informed its current independent registered public accounting firm, Deloitte & Co S.A. (“Deloitte”), that it will be dismissed as the Company’s independent registered public accounting firm effective upon completion of their audit of the Company’s consolidated financial statements as of and for the year ending December 31, 2021, and the issuance of their report thereon.

Deloitte’s reports on the Company’s consolidated financial statements for the fiscal years ended December 31, 2019 and December 31, 2020, do not contain any adverse opinion or disclaimer of opinion, and they are not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the fiscal years ended December 31, 2019 and December 31, 2020 and the subsequent interim period through November 2, 2021, there were (i) no disagreements with Deloitte on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, any of which, if not resolved to Deloitte’s satisfaction, would have caused it to make reference to the subject matter of any such disagreement in connection with its reports for such years or interim period and (ii) no “reportable events” requiring disclosure pursuant to paragraph (a)(1)(v) of Item 304 of Regulation S-K, except concerning the material weaknesses in the Company’s internal control over financial reporting disclosed in Item 4 of the Company’s Quarterly Reports on Form 10-Q for the quarterly periods ended June 30, 2020 and September 30, 2020, and reported in Item 9A of Amendment No. 1 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2019, filed with the Securities and Exchange Commission (the “SEC”) on December 23, 2020.

In accordance with Item 304(a)(3) of Regulation S-K, the Company has provided Deloitte a copy of the disclosures it is making in this Current Report on Form 8-K prior to filing with the SEC and requested that Deloitte furnish the Company with a letter addressed to the SEC stating whether or not Deloitte agrees with the above statements.  A copy of that letter, dated November 8, 2021, is filed as Exhibit 16.1 to this Current Report on Form 8-K.

Also on November 2, 2021, the Committee approved the appointment of Pistrelli, Henry Martin y Asociados S.R.L., a member firm of Ernst & Young Global Limited, (“EY”) as the Company’s new independent registered public accounting firm, contingent upon the execution of an engagement letter following completion of EY’s client acceptance procedures. EY’s appointment is for the Company’s fiscal year ending December 31, 2022, and related interim periods.

During the fiscal years ended December 31, 2019, and December 31, 2020, and the subsequent interim period through November 2, 2021, neither the Company nor anyone on its behalf has consulted with EY regarding (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, where either a written report or oral advice was provided to the Company that EY concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue, (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions to item 304 of Regulation S-K or (iii) any reportable event within the meaning of Item 304(a)(1)(v) of Regulation S-K.
