Press Release 03 August 2023 1 Vertical Aerospace Announces First Half-Year 2023 Financial Results Company Issues Shareholder Letter London, UK & New York, USA – 03 August 2023 Vertical Aerospace Ltd. (“Vertical” or the “Company”) (NYSE: EVTL; EVTLW), a global aerospace and technology company that is pioneering zero emission aviation, announces its financial results for the six months ended June 30, 2023. The Company has also issued a shareholder letter in conjunction with the filing of its first half-year results, which is posted to its investor relations website at investor.vertical-aerospace.com. Stephen Fitzpatrick, Vertical Founder and CEO, said: “We have seen fantastic momentum at Vertical in the first half of 2023 across our testing, certification, and commercial efforts. We have conducted our first untethered flights of our full-scale VX4, been granted a Design Organisation Approval from the CAA, and brought South Korea into our launch markets, with Kakao Mobility as a new customer. We are maintaining our disciplined spend with a £36m net operating loss for the first half of 2023. Over the next year, from 1 August 2023, we expect to spend c.£80m. Over this timeframe we will substantially progress our flight test programme both with crewed tests of our current prototype, and assembly and rigorous testing of our upgraded second full-scale VX4.” First Half-Year 2023 and Recent Operational Highlights • Vertical has continued to advance its flight test activities with progress in its thrustborne flight test campaign (including lifting, hovering, flying and landing vertically, by the thrust of the aircraft’s propulsion system). The flight tests have included numerous hovers, both tethered and untethered, as well as expanding the low-speed flight envelope with the Company’s full-scale VX4 prototype aircraft under remotely piloted conditions and powered by our proprietary battery systems. • Vertical is progressing the build of its second prototype VX4, which will incorporate learnings from tests conducted to date and advancements in its partners’, and its own in-house technology.

Press Release 03 August 2023 2 • Vertical has continued to make progress with its certification activities for the VX4 aircraft, including a detailed familiarisation session with the CAA on the aircraft design and certification basis. Further technical discussions are being advanced with the CAA, and technical familiarisation sessions with EASA, the FAA and the Japan Civil Aviation Bureau are expected before the end of 2023. Additionally, in June 2023, Brazil’s National Civil Aviation Agency informed the CAA that it has accepted Vertical’s application for validation of its type certificate in Brazil, which will enable the Company’s operations in Brazil. • In July 2023, Vertical announced the appointment of Stuart Simpson as Chief Financial Officer, joining in September 2023. Stuart is a seasoned leader, most recently serving as the Group Chief Financial Officer of Avast, a FTSE 100 company. Previously, Mr. Simpson held the roles of Interim Chief Executive Officer, Chief Financial Officer and Chief Operating Officer at Royal Mail, also a FTSE 100 company. Mr. Simpson has a long history in the automotive industry, working for General Motors and Rolls Royce and Bentley Motor Car Company. • In May 2023, Vertical announced that it is partnering with South Korean mobility-as-a-service company, Kakao Mobility, to evaluate and advance commercially sustainable urban air mobility travel solutions in South Korea. Kakao Mobility has agreed to pre-order, subject to certain conditions, up to 50 VX4 aircraft. The parties agreed to establish a joint working group with Kakao Mobility to drive the commercialisation of AAM services in South Korea, including the exploration of network and fleet planning, infrastructure requirements, regulatory development, and consumer awareness of eVTOL mobility solutions. First Half-Year 2023 and Recent Financial Highlights • Vertical reported a net operating loss of £36.0m for the six months ended June 30, 2023, compared to a net operating loss of £39.5m for the six months ended June 30, 2022. • The net operating loss for the period primarily includes the continued investment in the development of Vertical’s second full-scale prototype aircraft, and costs supporting our thrustborne flight campaign. • As of June 30, 2023, Vertical had cash and cash equivalents of £89.7m. Financial Outlook • The 2023 capital plan continues to remain on track, with net cash outflows to be used in operating activities in the second half of the year expected to be between £40m and £45m. • Net cash outflows incurred in the third quarter of the year will be in relation to the advancement of our airborne flight test programme and further investment in our second full scale prototype aircraft. • As previously announced, to support our ongoing capital requirements, fund our future operations and remain as a going concern, Vertical intends to raise additional capital during 2023. The above forward-looking statements reflect our expectations for the six months ending December 31, 2023 as of August 3, 2023, and are subject to substantial uncertainty. Our results are based on assumptions that we believe to be reasonable as of this date, but may be materially affected by many factors, as discussed below in “Forward-Looking Statements.”
