Embraer is a Brazilian aerospace company and the world's leading manufacturer of regional jets with up to 150 seats. Embraer operates across four segments: Commercial Aviation, Executive Aviation, Services & Support, and Defense & Security. Commercial Aviation is built around the E-Jet family — the E1 generation (170/175/190/195, seating 66–124 passengers) and the next-generation E2, which offers double-digit fuel burn improvements over the E1. The E175 dominates the U.S. regional market, where scope clauses in airline labor contracts effectively lock out Airbus and Boeing. Executive Aviation spans four business jet lines — the Phenom 100EX, Phenom 300E, Praetor 500, and Praetor 600 — sold to high-net-worth individuals, corporate flight departments, and charter operators. The Phenom 300E has been the world's best-selling light jet for 14 consecutive years. Defense is anchored by the KC-390 Millennium multi-mission transport (competing with the C-130J) and the A-29 Super Tucano light attack aircraft, with 11 countries having selected the KC-390. Services & Support is a recurring revenue stream covering MRO, spare parts, training, and maintenance programs across an installed base of roughly 4,400 aircraft. Embraer sells aircraft under fixed-price long-term contracts and holds a firm backlog of $31.6B. North America accounts for roughly 59% of revenue, and nearly all revenue is U.S. dollar-denominated, while most production costs are incurred in Brazilian reais.
