NOTICE TO THE MARKET

GAFISA S.A. (BOVESPA: GFSA3; NYSE, GFA) (" Gafisa " or " Company "), informs its shareholders and the market in general that in a meeting held on November 26, 2018, the Company's Board of Directors unanimously resolved to initiate the Company's delisting process, aiming at migrating the ADR Program (American Depositary Receipts) from Level 3 to Level 1. Therefore, the ADRs, which today are traded on NYSE (New York Stock Exchange), at the end of the process will be traded on the OTC (Over-the-Counter ) market.

The rationale behind this decision is based on the weighting of costs and benefits inherent to current ADRs program. In the past, during listing, the Company expected that benefits mainly relating to funding would surpass ADR Program Level 3 maintenance costs, including external audit, expenses to comply with SOX (Sarbanes Oxley) requirements and NYSE-related expenditures.

Over the years, as the ADR program responsiveness (liquidity and volume) significantly decreased, current and former Management reassessed the program's feasibility and sustainability.

Based on these analyses and taking into account the turnaround process the Company has been going through, its Board of Directors deemed necessary to fit the ADR Program into the Company's current financial condition, therefore, decided to migrate its listing from Level 3 to Level 1 (OTC), wherein other sector companies also trade their ADRs, with a broad acceptance from its investors.

Thus, we believe that the Company is taking another relevant step towards its commitment to adjust costs and processes.

Details of this process are described in the Material Fact released by the Company on November 26, 2018.
