INFORMATION CONTAINED IN THIS REPORT ON FORM 6-K

On September 17, 2025, Vertical Aerospace Ltd. (the “Company”) will host a Capital Markets Day in which it will provide an update on recent progress on execution of its strategy, improved revisions to its business plan, details of its manufacturing plans, and details on the anticipated capital necessary to achieve certification of its all-electric VX4 aircraft in 2028.

Progress on FlightPath 2030

In November 2024, the Company launched Flightpath 2030, its strategy for market leadership before the end of the decade through embedding a pioneering culture, redefining aerospace best practice, intelligent partnering and being safety obsessed. Flightpath 2030 set out defined goals for the Company to achieve by 2030.

Today, reflecting the Company’s subsequent progress and learnings, expected future aircraft upgrades, including to increase passenger capacity to up to six passengers, and in anticipation of having three distinguishable but complementary business lines comprising the all-electric VX4, the recently announced hybrid-electric variant, and aftermarket services, principally battery sales, the Company announces the following revised or new operational targets and financial projections:

Operational targets

·	an increase in the target cumulative number of aircraft deliveries to its customers from at least 150 to at least 175 units by end<br>2030;
·	an increase in the target annual aircraft production run-rate from 200 to greater than 225 units as at Q4 2030, collectively across<br>the VX4 and the hybrid-electric variant;
---	---
·	an increase in the target annual aircraft deliveries from 700 in the medium-term to approximately 900 units in 2035, collectively<br>across the VX4 and the hybrid-electric variant;
---	---
·	annual battery deliveries to reach approximately 45,000 units in 2035; and
---	---
·	expected regulatory certification of the hybrid-electric variant with the UK Civil Aviation Authority (the “CAA”) in 2029.
---	---

The Company continues to work closely with the CAA as it progresses its piloted flight test campaign. The VX4’s final phase, piloted transition flight testing, is expected to be achieved by end 2025, with flight testing of the hybrid-electric variant targeted to begin in 2026.

Financial projections

The Company reiterates its intention to become sustainably cash generative and, assuming the achievement of the FlightPath 2030 milestones and certification of the VX4 in 2028, now projects:

·	an increase in expected free cash flow from break-even in 2030, to achieve cash break-even by end 2029, with more than $100 million<br>of positive free cash flow in 2030;
·	to generate approximately $1.0 billion consolidated annual revenues by 2030, at a gross profit margin of 20%, increasing to approximately<br>$10.7 billion consolidated annual revenues by 2035, at a gross profit margin of 40%;
---	---
·	expected 2030 revenue contribution by business line to be 72% VX4 aircraft sales (59% in 2035); 21% hybrid-electric aircraft sales<br>(16% in 2035); and 7% aftermarket services (25% in 2035); and
---	---
·	expected 2030 gross profit magin contribution by business line to be 60% VX4 aircraft (60% in 2035); 28% hybrid-electric aircraft<br>(12% in 2035); and 12% aftermarket services (28% in 2035).
---	---

Manufacturing and Production

Vertical is headquartered in Bristol, England, one of the largest aerospace hubs in the United Kingdom, where it has its core engineering research and development facility. It also has a dedicated flight test centre located at Cotswold Airport in Kemble, England, and a battery development and testing facility in Avonmouth, England.

The Company today announces its intention to utilise a modular manufacturing model, under which the VX4 will effectively be kit assembled, allowing for smaller-scale, single production lines to meet orders and maintain full capacity to be scaled efficiently as demand grows.

To achieve this plan, the Company has confirmed its production facilities for initial low-rate production. These facilities are an expanded site at Cotswold Airport, located adjacent to its existing flight test centre, which will support the initial entry-into-service aircraft, with expected capacity to fulfill the production of greater than 25 VX4 aircraft annually. Vertical has signed a five-year lease for the initial phase of this expanded facility, as well as a letter of intent for the subsequent phase to build an additional permanent hangar, which will together take Vertical’s total footprint at the Airport to approximately 100,000 square feet.

Furthermore, the Company has signed Heads of Terms with the landlord of the existing battery development and testing facility for a purpose-built facility, adjacent to the existing battery centre, to provide capacity for battery production into 2030. This expansion will include an additional approximate 30,000 square feet, pursuant to a 15 year lease, with target occupation in 2026, bringing the Company’s total footprint at the battery centre to approximately 45,000 square feet.

The Company is evaluating the locations for its first full-rate aircraft and battery production sites, which it expects to confirm in 2026 with the intention for these sites to come online in line with its planned manufacturing ramp up.

Capital Resources

The Company expects its capital needs to continue to be significant in the foreseeable future as it expands its business and progresses towards certification of the all-electric VX4 aircraft.

It is currently estimated that the Company will require an additional approximately $700 million in capital pursuant to its base case plan of targeting VX4 certification in 2028.

This amount is comprised of (i) approximately $550 million in people and operating expenses, which is the core business expenditure, primarily driven by engineering resources and supporting infrastructure as well as manufacturing costs necessary for the pre-production, certification-ready aircraft; (ii) approximately $225 million in non-recurring engineering costs (NRCs) in connection with the Company’s signing its long-term supply contracts with its certification partners; (iii) approximately $75 million in capital expenditures, relating to aircraft assembly and battery facilities; (iv) hybrid powertrain development up to an assumed customer-funded contract; and (v) program contingency. The gross funding costs are expected to be partially offset by current cash in bank, as of August 31, 2025, excluding assumptions around future capital raises and income, including anticipated customer pre-delivery payments. The Company will continue to evaluate opportunities to reduce its net funding needs, by inflows from tax credits, customer pre-delivery payments, and government support.

Vertical Aerospace Announces ManufacturingFacilities and Updates on Path to Certification During Capital Markets Day

·	Secures<br> initial VX4 aircraft assembly and battery production facilities to support certification<br> and early production
·	Reiterates<br> clear path to certification in 2028 and shares $700 million spend requirement to certification
---	---
·	Provides<br> improved financial and operational targets for 2030 and beyond, reflecting momentum over<br> the past year, integration of the hybrid-electric business plan, and increased certainty<br> around supplier and manufacturing plans
---	---

London, UK; New York, USA – September17, 2025 – Vertical Aerospace (Vertical) [NYSE: EVTL], a global aerospace and technology company that is pioneering electric aviation, will host its Capital Markets Day today in New York City, beginning at 2:00 p.m. ET.

The event will provide key updates on the Company’s Flightpath 2030 business strategy, certification and manufacturing progress, and financial outlook. A live webcast for the event is available here.

Initial Production FacilitiesSecured

Vertical will announce its first manufacturing sites to support certification and early production:

·	Aircraft assembly at expanded Cotswold Airport site – New facility adjacent<br> to existing Flight Test Centre will have capacity to produce 25+ VX4 aircraft annually<br> and brings Vertical’s total footprint at Cotswold Airport to ~100,000 sq ft.
·	Battery production at expanded Avonmouth site - Adjacent to Vertical’s existing<br> Energy Centre, this new 30,000 sq ft battery facility will triple capacity for battery production.<br> This facility will provide production capacity into 2030 and brings Vertical’s total<br> Energy Centre footprint to ~45,000 sq ft.
---	---

Locating both facilities alongside existing operations reduces integration risk, drives efficiency, and enables a seamless ramp from prototype through certification and initial production aircraft. Vertical continues to progress site selection for its full-rate production and battery facilities, with locations in the UK and beyond under consideration and a final decision expected in 2026, ready to meet Vertical’s subsequent manufacturing ramp up.

Efficient and Cost-EffectiveCertification Path

Vertical will reaffirm its plan to certify the all-electric VX4 by 2028, requiring $700 million in funding to reach this milestone.

Due to its focused OEM business model, low operating costs relative to the industry, efficient manufacturing plans and greater clarity of supplier costs, the Company is able to project requirements to reach certification by 2028. The approach of the UK Civil Aviation Authority (UK CAA) and European Union Aviation Safety Agency (EASA), who are collaborating on eVTOL certification safety standards, front-loads the certification process and minimizes late-stage surprises or delays, providing greater confidence to Vertical’s plans and timelines.

Updated Financial Outlook

Vertical will provide revised targets for 2030 and beyond, reflecting momentum over the past year, integration of the hybrid-electric business plan, and increased certainty around supplier and manufacturing plans:

·	Deliveries: at<br> least 175 aircraft delivered cumulatively by 2030, versus prior guidance of at least 150.
·	Manufacturing:<br> over 225-unit per annum manufacturing run-rate (Q4-2030), versus prior guidance of over 200-unit<br> per annum run-rate (Q4-2030), with plans to scale to target annual aircraft deliveries of<br> 900 in 2035, versus prior guidance of 700 aircraft deliveries in the medium-term.
---	---
·	Batteries: ~45,000 battery units delivered in 2035.
---	---
·	Margins: Consolidated<br> gross margin of 20% in 2030, rising to ~40% by 2035.
---	---
·	Cash Flow: over $100 million positive operating cash flow in 2030, versus prior guidance<br> of breakeven.
---	---

‘Transition’ flighton track for year end

Vertical is on track to complete transition testing - the final stage of its piloted flight programme - by the end of 2025 and announced it will begin hybrid-electric flight testing in 2026.

Transition will demonstrate the VX4’s ability to shift seamlessly between vertical lift (“helicopter mode”) and wingborne flight (“airplane mode”). This 20-second piloted manoeuvre is the defining capability of tiltrotor eVTOLs, enabling operations from rooftops, vertiports and heliports. Completion will mark a major technical unlock, a key de-risking milestone on the path to certification and revenue generation.

Stuart Simpson, CEO of Vertical Aerospace,said: “Since launching Flightpath 2030, we’ve moved from ambition to execution. Piloted flight tests, the hybrid-electric programme, secured facilities, and greater cost visibility have meaningfully de-risked our plan and strengthened our financial outlook. With the final technical proof point - transition flight - anticipated by year-end, we now have a clear, efficient path to certification and commercialization at scale, positioning Vertical to lead the next era of electric flight.”
