The ratio change will be effected through an amendment to the Embraer's Third Amended and Restated Deposit Agreement.

Each holder of record of ADSs as of the close of trading on November 9, 2026 (the record date) will receive, after the close of trading on November 13, 2026, three additional ADSs for every ADS held on the record date. Trading is expected to begin on a split-adjusted basis under the new ratio at market open on November 16, 2026.

The ratio change will not affect Embraer's underlying common shares, and no new common shares will be issued in connection with the ratio change. Similarly, there will be no change in the economic value of the ADS holders' ownership interests.

Embraer's ADSs will continue to trade on the New York Stock Exchange under the ticker symbol "EMBJ". JPMorgan Chase Bank, N.A., as depositary for Embraer's ADS program, will implement the ratio change.
