Embraer reports 65 aircraft delivered in the second quarter, up 48% quarter-over-quarter

São Paulo (SP), Brazil, July 2, 2026 – Embraer (NYSE: EMBJ / B3: EMBJ3) delivered 65 aircraft in 2Q26, marking its strongest second-quarter delivery performance over the past 16 years. Deliveries increased 48% quarter-over-quarter (qoq) and 7% year-on-year (yoy). In 1H26, Embraer delivered a total of 109 aircraft, circa 20% more than the 91 aircraft delivered in 1H25, supported by continued progress in the company's production leveling initiatives.

Commercial Aviation delivered 20 new aircraft during 2Q26 - 6 of which were E195-E2 models, Embraer's largest aircraft currently in production in the segment. The business unit's volume increased 100% in comparison with 1Q26 when it delivered 10 aircraft, and 5% in comparison with 2Q25 when it delivered 19 aircraft.

Executive Aviation delivered 45 aircraft during the quarter, up 55% qoq from 29 aircraft in 1Q26, and up 18% yoy from 38 aircraft in 2Q25. Growth was driven by higher deliveries across both small and medium jet segments, reflecting sustained demand and continued operational execution.

There were no deliveries in the Defense & Security segment during the quarter.

Embraer continues to expect deliveries between 80 and 85 aircraft in Commercial Aviation (midpoint up 6% yoy) and between 160 and 170 aircraft in Executive Aviation (midpoint up 6% yoy) in 2026.
