Capital Markets Day: Manufacturing and Certification Announcements During its Capital Markets Day, Vertical Aerospace announced the establishment of its first dedicated manufacturing sites. The expanded facility at Cotswold Airport will handle aircraft assembly, with an annual capacity exceeding 25 VX4 units and a total footprint of approximately 100,000 square feet. The proximity to Vertical’s Flight Test Centre is intended to streamline the transition from development to production and facilitate rapid iteration during certification. Battery production will be concentrated at an expanded facility in Avonmouth, tripling the company’s battery manufacturing capacity and bringing the Energy Centre’s total space to 45,000 square feet. This focus on in-house battery technology reflects the critical role of batteries in eVTOL performance, particularly in terms of energy density, charging speed, and operational economics. Vertical’s manufacturing strategy relies on modular, kit-based assembly, with smaller, single production lines designed to scale efficiently as demand grows. The company has secured a five-year lease for the initial phase at Cotswold, with options to expand as production ramps up. Evaluation of sites for full-rate production, both in the UK and internationally, is ongoing, with decisions expected by 2026. “The company’s ability to secure initial manufacturing sites while maintaining a capital-efficient approach, requiring only $700 million to reach certification compared to competitors who have raised significantly more funding, demonstrates a strategic advantage.” Flight Testing and Technical Validation Vertical’s systematic flight testing program has achieved several key milestones. The completion of Phase 3 wingborne flight testing in September 2025 validated the VX4’s design and handling, with the aircraft successfully transitioning to wingborne flight and matching performance predictions. This phase followed earlier tethered and thrustborne tests, with each stage providing critical data for certification. The flight test program has covered over 250 miles and generated 22 billion data points, supporting both technical validation and regulatory engagement. The UK Civil Aviation Authority (CAA) extended Vertical’s Permit to Fly after rigorous safety reviews, and ongoing collaboration with EASA (European Union Aviation Safety Agency) is aimed at achieving concurrent certification. Vertical’s proprietary battery technology, developed through six generations, underpins the VX4’s performance. The company’s focus on certifiable, high-power battery systems is seen as a competitive advantage, addressing the demanding power requirements of eVTOL operations. Financial Position and Funding Vertical Aerospace has raised $468.8 million to date, considerably less than some competitors, yet has achieved comparable technical milestones. The company’s recent $90 million public offering, including a $50 million investment agreement with Mudrick Capital, strengthened its balance sheet and provided the capital needed to accelerate development. Mudrick Capital’s involvement includes converting $130 million in debt to equity, further improving Vertical’s financial position. The company projects that $700 million in total funding will be required to reach certification by 2028, with a target of cash break-even by 2030 and gross margins exceeding 40%. This capital-efficient model, combined with a focused OEM approach and strong supplier partnerships, is intended to provide a sustainable path to profitability, even as the broader industry faces funding and execution challenges. Regulatory Progress and Market Position Vertical Aerospace’s regulatory strategy is distinguished by active certification projects with five major agencies: the UK CAA, EASA, FAA (US), Brazil’s ANAC, and Japan’s JCAB. The expansion of its Design Organisation Approval by the UK CAA in July 2024 allows Vertical’s engineers to sign off on increasing aspects of compliance, streamlining the certification process. The collaborative approach between the UK CAA and EASA is particularly significant, enabling concurrent certification and reducing regulatory risks. The appointment of Patrick Ky, former EASA Executive Director, to Vertical’s board further strengthens the company’s regulatory expertise and credibility. Vertical’s order book includes approximately 1,500 aircraft valued at $6 billion, with commitments from American Airlines, Japan Airlines, AirAsia, GOL, and Bristow Group.
