Item 3.Source and Amount of Funds or Other Consideration.

In October 2011, BTG Pactual, indirectly through its vehicle BPMB Digama Participações S.A., converted all the convertible debentures (the “Convertible Debentures”) issued by Estre Ambiental S.A. (“Estre”) then held by BTG Pactual into 16,818,904 of Estre’s common shares, then representing 20.9% of Estre’s capital stock. This was the first equity interest in Estre that any BTG Pactual entities beneficially owned. The Convertible Debentures were issued by Estre in August 2011. Subsequent to the acquisition of Estre’s common shares by BPMB Digama Participações S.A., BTG Pactual completed a number of internal reorganizations and additional capital investments in Estre which resulted in relevant BTG Pactual entities referred to below holding Estre’s common shares.

On December 21, 2017, the consummation of a business combination transaction (the “Transaction”) took place pursuant to the Amended and Restated Business Combination Agreement, dated as of September 11, 2017, as amended on December 7, 2017 and December 13, 2017 (the “Transaction Agreement”), by and among Boulevard Acquisition Corp. II (“Boulevard”), Estre, the Issuer (formerly named Boulevard Acquisition Corp II Cayman Holding Company) and BII Merger Sub Corp (“Merger Sub”).

Upon consummation of the Transaction, among other things, the former shareholders of Estre immediately prior to consummation of the Transaction received Ordinary Shares in exchange for the shares that such shareholders held in Estre. Accordingly, pursuant to the Transaction Agreement, BTG Pactual FIP received 9,097,026 Ordinary Shares, FIP Turquesa received 1,089,453 Ordinary Shares and FIP Iron received 197,441 Ordinary Shares.

10

References to and the description of the Transaction Agreement set forth above are not intended to be complete and are qualified in their entirety by reference to the full text of the Transaction Agreement (including Amendment No. 1 and Amendment No. 2 thereto), which are filed as exhibits hereto and are incorporated by reference herein.

In addition, pursuant to a Private Agreement for Payment in Kind and Other Agreements entered into between Banco BTG Pactual S.A., Mr. Wilson Quintella Filho and Cygnus Asset Holding Ltd. (an entity beneficially owned by Mr. Quintella) on December 21, 2017 (the “Payment in Kind Agreement”), Cygnus Asset Holding Ltd. transferred to Banco BTG Pactual S.A. on December 22, 2017 a total of 9,875,718 Ordinary Shares, such transfer of Ordinary Shares being made in payment in kind of R$325 million of debt that was originally owed personally by Mr. Quintella and transferred to Cygnus Asset Holding Ltd. before the Payment in Kind. The number of Ordinary Shares transferred was equal to R$325 million divided by the product of $10.00 per Ordinary Share and the exchange rate from Brazilian Reais to US Dollars on the business day immediately before the closing date of the Transaction.

The foregoing is a summary of the material terms of the Payment in Kind Agreement, and is qualified in its entirety by reference to the full text of the Payment in Kind Agreement, a copy of which is attached hereto as Exhibit 4 and incorporated herein by reference.
