About Vertical Aerospace

Vertical is creating a safer, cleaner and quieter way to travel. Vertical's VX4 is a piloted, four passenger, Electric Vertical Take-Off and Landing (eVTOL) aircraft, with zero operating emissions. Vertical will also be launching a hybrid-electric variant, offering increased range and mission flexibility to meet the evolving needs of the advanced air mobility market.

Vertical combines partnering with leading aerospace companies, including GKN, Honeywell and Leonardo, with developing its own proprietary battery and propeller technology to develop the world's most advanced and safest eVTOL.

Vertical has c.1,500 pre-orders of the VX4, with customers across four continents, including American Airlines, Japan Airlines, GOL and Bristow. Certain customer obligations are expected to be fulfilled via third-party agreements. Headquartered in Bristol, the epicentre of the UK's aerospace industry, Vertical's experienced leadership team comes from top tier automotive and aerospace companies such as Rolls-Royce, Airbus, GM and Leonardo.

Exhibit 99.2

RISK FACTORS

The risk factors set forth below supplements the risk factors included in our Annual Report on Form 20-F for the year ended December 31, 2024, which we refer to as our Form 20-F for 2024. An investment in our securities involves a number of risks. You should carefully consider the following information about the risks we face, together with other information in our Form 20-F for 2024 and other information incorporated by reference into our registration statement, when you make investment decisions involving our securities. If one or more of these risks were to materialize, it could have a material adverse effect on our financial condition, results of operations, cash flows or prices of our securities. Unless otherwise specified below, definitions of the defined terms used below are included in our Form 20-F for 2024.

Risks Related to Our Business and Industry

Development of a hybrid-electric vertical take-off and landing variant of the VX4 is subject to significant risks, including technological, regulatory and operational challenges.

On May 12, 2025, we announced the development of a hybrid-electric vertical take-off and landing (“VTOL”) variant of the VX4 aircraft. Developing a hybrid aircraft involves significant technical complexity, extensive research and development, and substantial investment. Our success depends on our ability to design, test, and certify a new type of aircraft that integrates both conventional and electric propulsion systems, a process that presents numerous engineering, safety, and performance challenges. Any product defects or any other failure of our aircraft to perform as expected could harm our reputation and result in adverse publicity, delays in or inability to obtain certification, lost revenue, delivery delays, product recalls, product liability claims, harm to our brand and reputation, and significant warranty and other expenses.

Moreover, the regulatory pathway for hybrid aircraft is still evolving. Certification of novel propulsion technologies and aircraft configurations requires close coordination with aviation authorities, including the CAA, EASA and the United States Federal Aviation Authority (“FAA”), as well as local regulators in other countries where we intend to sell aircraft. There can be no assurance that we will obtain certification of our aircraft in the time frame that we project, or at all, which would impact our overall timetable to sell our aircraft. Should there be any delays to our projected approval timetables, this could have a material effect on our ability to deliver any orders to our customers, which could have a material adverse effect on our relationships with our current and existing customers and adversely affect our reputation.

Even if we successfully develop and certify our aircraft, we may not achieve commercial viability. Market adoption of hybrid-electric aircraft depends on customer confidence and operating cost advantages. If we fail to meet performance, reliability, or cost expectations, demand for our aircraft could be limited.

Any of the above factors, individually or in combination, or any of the other risks relating to our VX4 aircraft set forth in our Form 20-F for 2024 – which risks shall be deemed to apply equally to our hybrid-electric VTOL variant of the VX4 aircraft – could have a material adverse effect on our business, financial condition and results of operations.

The Company may become subject to certain specific business risks as a result of supplying equipment and services to government contractors.

The Company’s announcement of the development of a hybrid-electric VTOL variant of the VX4 aircraft enables new potential applications in defense, logistics and commercial sectors, including air ambulance services, which require longer range and higher payload than current eVTOL platforms are expected to deliver.

The contractual partners of the sectors we are targeting with our hybrid-electric VX4 variant are expected to include government contractors, which would subject to the Company to certain specific business risks related to government contracts. In particular, government contracts are often subject to specific procurement regulations, contract provisions and a variety of other requirements relating to the formation, administration, performance and accounting of these contracts. Many of these contracts include express or implied certifications of compliance with applicable regulations and contractual provisions. If the Company fails to comply with any such regulations, requirements or statutes, including any environmental, health and safety laws or regulations, its targeted future agreements with the government contractors could be terminated or the Company could be suspended or excluded from entering into any additional contracts with government contractors in the future.

The growth of the Company’s business may be impacted by its ability to enter into partnerships with government contractors and on its successful procurement of additional partnerships. However, demand from the government contractors is often unpredictable, and significantly depends upon government budget trends. There are number of factors that could impede the Company’s ability to generate revenue in relation to government contracts, including, but not limited to:

The occurrence of any of the foregoing could cause governments and governmental agencies to delay or refrain from purchasing the finished products supplied by government contractors, which may in turn affect demand for the Company’s products in the future or otherwise have an adverse effect on its business, operating results and prospects.
