Ubisoft Q1 net bookings at $289M, new Assassin's Creed sells 3.5M copies in 14 days

Ubisoft reported first-quarter net bookings of €256 million for fiscal year 2026-27, down 9% year-on-year but slightly above guidance. The decline reflects a high comparison base from Assassin's Creed Shadows' March 2025 release. The quarter saw record performance from Invincible: Guarding the Globe, whilst Rainbow Six Siege performed in line with expectations. Assassin's Creed Black Flag Resynced launched in July, achieving an 84 rating on OpenCritic and Metacritic. The game sold 3.5 million copies within its first 14 days, exceeding annual expectations. Ubisoft appointed industry veteran Christoph Hartmann as general manager of Creative House 2.
