Vertical Aerospace Secures Tier‑1 Partner and Strong Cash to De‑Risk eVTOL Production

Breaking: Vertical Aerospace Secures Major Manufacturing Pact With aciturri Amid Stable Half-Year Performance

In the opening week of August 2025,Vertical Aerospace announced a long‑term manufacturing alliance with Aciturri Aerostructures,a leading global supplier with deep roots in traditional aviation. The move came alongside a steady first half of 2025,signaling a pivotal shift in the company’s trajectory.

As the race to roll out electric air taxis accelerates, engineers confirm that flying an aircraft is only the first challenge. The bigger hurdle is proving it can be built reliably, affordably, and at scale.

Vertical Aerospace now presents a credible answer to that challenge, offering investors a clearer path to the long‑term promise of the eVTOL market.

Solving the Manufacturing Puzzle With a Proven Partner

The supply chain is as vital as the design for any new aircraft program. The Aciturri deal anchors Vertical’s manufacturing strategy, designed to cut risk and conserve capital.

The agreement covers the production of the entire airframe structure, including the high‑lift wing, the passenger fuselage, and the pylons that mount the electric propulsion units.

By consolidating a large share of the airframe supply with a single,experienced partner,Vertical aims to streamline future production and reduce the risks inherent in building a brand‑new factory network from scratch.

Aciturri is a Tier 1 supplier, a term used in aerospace for primary, direct contractors to the original equipment manufacturer. They are not a startup; Aciturri brings decades of experience supplying critical components to major names in aviation, including Airbus,Boeing,and Embraer.

This established credibility helps ensure the VX4 airframe will meet the stringent standards demanded by the industry. Aciturri’s track record also includes airframes for other eVTOL programs, demonstrating their ability to bridge traditional certification with novel electric aviation technology.

from an investment perspective, the move aligns with Vertical’s asset‑light strategy. Rather than pouring hundreds of millions into factories and tooling, the company leverages a world‑class partner’s capabilities and existing infrastructure. This approach frees Vertical to concentrate on core strengths – aircraft design, battery and software integration, and navigating certification – while preserving capital for other milestones.

Funding Stability Meets Flight Acceleration

A solid manufacturing plan rests on a solid financial foundation.Vertical’s first‑half 2025 results, published in early august, show disciplined spending while pushing critical tech milestones forward. The company reported a cash position near $137 million,reinforced by a $69 million capital raise in July,extending the runway into mid‑2026.

This financial runway matters for a pre‑revenue technology company,signaling resilience as it pursues milestones ahead. Management kept guidance for net operating cash outflow in 2025 at around $110 million to $125 million, a sign of budget discipline following the new industrial partnership.

Simultaneously occurring, the flight program has gained momentum.Piloted wingborne tests have progressed with multiple flights conducted by two different pilots in open European airspace, serving as a continuation of the July airport‑to‑airport presentation. The company remains on track to complete the year’s most technically challenging phase – transitioning from vertical lift to winged forward flight – in the second half of 2025.

this balance of financial prudence and flight‑test progression underscores Vertical’s ability to manage multiple complex workstreams simultaneously.

Building a Complete Ecosystem

The Aciturri partnership adds to a growing ecosystem that already includes a Bristow collaboration and strategic leadership additions. A team‑building effort, including the appointment of Lord Andrew Parker, the former head of Britain’s MI5, to the board, brings high‑level credibility and potential access to defense and government opportunities. The long‑range hybrid‑electric variant remains a focal point for potential revenue beyond urban air mobility.

For observers, the investment narrative has shifted from asking if the aircraft can fly to how it will be built and sold. By signing Tier 1 suppliers,maintaining financial discipline,and advancing flight tests,Vertical Aerospace is laying a more tangible foundation for long‑term value.
