Horizon Aircraft Provides Technical Progress Update

Company is now building a full-scale aircraft targeted for initial testing in 18 months

Toronto, Canada, September 10, 2025 – New Horizon Aircraft (Nasdaq: HOVR), doing business as Horizon Aircraft (“Horizon” or the “Company”), an advanced aerospace engineering company and developer of one of the world’s first hybrid electric Vertical Take-Off and Landing (eVTOL) aircraft, provides a comprehensive technical progress update.

Throughout the first half of 2025, the technical team has hit several important milestones that validate Horizon’s unique and practical hybrid VTOL concept:

● Transition Flight – Horizon completed one of the world’s first ever successful fan-in-wing forward transition flights in May 2025 with its large-scale prototype aircraft;

● Full-Scale Prototype – Horizon is now building a full-scale aircraft and intends to have an aircraft ready for initial testing in 18 months;

● Platform Level Architecture – Horizon completed architecture development for the full-scale, non-conforming prototype;

● Propulsion Technology – Main wing propulsion units that power the unique and patented HOVR Wing technology have been fabricated and are undergoing active testing and iteration;

● Simulation – The technical team continues to develop its sophisticated simulation environment that was instrumental in accelerating the development of the large-scale aircraft that recently successfully transitioned to forward flight;

● Certification – With plans to certify the aircraft for flying under Instrument Flight Rules (IFR) and for Flight Into Known Icing (FIKI), Horizon has already spoken with Transport Canada Civil Aviation (TCCA) and is working with technical experts in Canada to make this a possibility; and

● Technical Team – Horizon increased its team of senior designers and engineers by nearly 50% in 2025 through the addition of very accomplished personnel, many of whom are recognizable in their field of expertise.

“This has already been an incredible year for the technical team, and we’re not done yet. A historic full transition to forward flight of the large-scale prototype, construction and testing of many full-scale underpinning technologies, and maturation of our many professional aerospace processes has been rewarding for our entire team to be a part of,” said Brandon Robinson, CEO.

“Now our team’s focus is on the design of the full-scale aircraft, which we expect to complete within 18 months.”
