Notice to the Market

Banco Bradesco S.A. informs our shareholders and the market in general that on September 29, 2017 the United States District Court for the Southern District of New York (“Court”) ruled on Defendants' pending motion to dismiss, the Class Action, filled on June 3, 2016

The Court granted in part and denied in part Defendants' motion to dismiss, limiting the proposed class to investors that purchased Bradesco’s preferred American Depositary Shares (“ADS”) between August 8, 2014 and July 27, 2016.

The Court granted the leader plaintiff leave to file a second amended complaint in 30 days that attempts to remedy the deficiencies identified by the Court in its ruling. At the end of this period, the Court will address the schedule of the discovery phase if the leader plaintiff does not attempt to amend its complaint.
