EXPLANATORY NOTE

This post-effective amendment no. 2 (as may be amended after the date hereof, the “Post-Effective Amendment No. 2”) is filed with the Securities and Exchange Commission (the “Commission”) by Estre Ambiental, Inc. (the “Registrant”) and amends the registration statement initially filed with the Commission on Form F-4 (File No. 333-220428) on September 12, 2017, which was declared effective by the Commission on December 8, 2017 (the “F-4 Registration Statement”). The F-4 Registration Statement was amended by a post-effective amendment no. 1 on Form F-1 filed with the Commission on July 12, 2018 (the “Post-Effective Amendment No. 1”), which was declared effective by the Commission on July 31, 2018 (as such F-4 Registration Statement has been amended, the “Registration Statement”).

At the time that the F-4 Registration Statement was declared effective, the F-4 Registration Statement registered, among other things, 28,250,000 ordinary shares of the Registrant (the “Underlying Shares”) that are issuable upon the exercise of the public warrants of the Registrant (the “Public Warrants”), the offering of which was registered by the F-4 Registration Statement. Pursuant to the Post-Effective Amendment No. 1, the Registrant deregistered 3,748,601 Underlying Shares and accordingly the offering of the remaining 24,501,399 Underlying Shares is ongoing and remains registered pursuant to the Registration Statement. Such 24,501,399 Underlying Shares are the only securities that are registered pursuant to the Registration Statement that have not been sold.

Each Public Warrant is currently exercisable for one Underlying Share at a price of US$11.50 per Underlying Share. The Public Warrants are significantly “out-of-the-money”. On January 13, 2020, the closing price for the ordinary shares of the Registrant on NASDAQ was US$0.57 per ordinary share. As previously disclosed in filings with the Commission, the Registrant is currently experiencing significant liquidity constraints. In view of the costs associated with updating the Registration Statement and maintaining a current prospectus relating thereto, the Registrant has decided to terminate the effectiveness of the Registration Statement and deregister the Underlying Shares.

Accordingly, this Post-Effective Amendment No. 2 is being filed to terminate the effectiveness of the Registration Statement and to remove from registration all securities registered but not sold pursuant to the Registration Statement, which unsold securities comprise solely 24,501,399 Underlying Shares.

SIGNATURE

Pursuant to the requirements of the Securities Act of 1933, as amended, and Rule 478 thereunder, the Registrant has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of São Paulo, State of São Paulo, Brazil, on January 15, 2020.
