 Exhibit 4.19 

English Language Summary of the Acquisition of Liquigás Distribuidora S.A. by Companhia Ultragaz S.A. dated November 17, 2016 

On November 17, 2016, Ultrapar Participações S.A. (“Ultrapar”) and its subsidiary Companhia Ultragaz S.A.
(“Ultragaz”) executed the Sale and Purchase Agreement of Shares and Other Covenants (“SPA”) for the acquisition (the “Acquisition”) of the entirety of Petróleo Brasileiro S.A. –
Petrobras’s (the “Seller”) equity interest in Liquigás Distribuidora S.A.—Liquigás (“Liquigás”). 

Purchase Price 
 The total price due for the
Acquisition is R$2,665,569,000.00 (two billion, six hundred sixty-five million, five hundred sixty-nine thousand reais) (“Base Acquisition Price”), which shall be adjusted according to
the average CDI rate, calculated daily and published by the Securities Custody and Settlement Center (Central de Custódia e Liquidação Financeira de Títulos—CETIP), between the SPA’s execution date and
the closing date of the Acquisition (“Closing Date” and “Acquisition Price”, respectively). 
 The Base Acquisition Price
corresponds to an enterprise value of R$2,800,000,000.00 (two billion, eight hundred million reais), plus the value attributed to certain non-operational fixed assets held by Liquigás in the city of Osasco (the “Osasco
Assets”) minus Liquigás’ net debt as of December 31, 2015 (corresponding to R$196,031,000.00 (one hundred ninety-six million and thirty-one thousand reais)). 

In the event that the Osasco Assets are transferred by Liquigás to a third party prior to the Closing Date, the Acquisition Price shall be further
reduced by the value of such potential sale of the Osasco Assets, adjusted according to the variation of the CDI rate in the period between execution date of the SPA and the Closing Date. The Acquisition Price is subject to further price adjustments
based on variations in (i) Liquigás’ working capital and (ii) Liquigás’ net debt position, in each case for the period between December 31, 2015 and the Closing Date (to be calculated after the Closing Date).
