NOTICE TO THE MARKET

São Paulo, SP, Brazil, January 22, 2019 - GAFISA S.A. (BOVESPA: GFSA3) (“Gafisa” or “Company”), taking into consideration the content of the Material Fact released today, inquired the GWI Group about any planned developments, and the GWI Group requested to publish its notice hereinbelow.

“The GWI Group, which controls GWI Asset Management S.A., a corporation headquartered in the City and State of São Paulo, at Av. Brigadeiro Faria Lima, 3900, 6º andar, conj. 602 ("GWI"), pursuant to CVM Instruction No. 358/2002, amended by CVM Instruction No. 449/07, in attention of clarifications requested by GAFISA S.A. ("Company"), especially referring to eventual positioning of GWI, hereby clarifies the following:

Since GWI Group now holds over 50% of total shares issued by the Company, even if not settled yet, this occurred due to matters related to the latest market trades, unintentionally, therefore, not being planned, without any intention of takeover.

Anyway, in observance to transparency, best practices and in a conscientious attitude,  GWI forwarded this notice to the Company, and for the time being, it assesses the procedures to be adopted jointly with its advisors, in compliance with provisions of the Company’s Bylaws, the Brazilian Corporation Law, the rules issued by the Securities and Exchange Commission of Brazil (CVM), and the regulations of the Stock Exchanges where securities issued by the Company are accepted for trading.

Having nothing to add, we remain at your disposal for any further clarification”.
