A recent analysis published on October 1, 2025, indicated a six-month delay in the first flight of Eve Holding's EVE-100 engineering prototype. Flight testing for this crucial development vehicle is now expected to commence in late 2025 or early 2026, a shift from earlier projections of initial flights 'till this year' (2025).
The engineering prototype, assembled in July 2024, is currently undergoing ground testing to validate aerodynamic and performance models and refine technical aspects. This delay specifically pertains to the initial flights of this remotely piloted, simplified vehicle, which is vital for validating core design principles.
Despite this operational delay, Eve Holding recently raised $230 million in equity capital, strengthening its liquidity position. This funding is intended to support operations and mitigate financial risks as the company progresses towards certification and eventual production ramp-up, with formal certification flight tests for conforming prototypes still planned to commence in 2026.
