INFORMATION CONTAINED IN THIS REPORT ON FORM 6-K

16 members of the Board of Directors and senior leadership team of Vertical Aerospace Ltd. (the “Company”) have informed the Company that, commencing on November 11, 2025, they have effected a series of open market share purchases in the Company’s ordinary shares. Such open market share purchases were conducted by these persons solely in a personal capacity and not in any relation to their role as a member of the Board or the senior leadership team of the Company.

This follows the Company’s announcement in May 2025, noting a series of open market share purchases conducted by the Chairman of the Board of Directors of the Company and two fellow Board members in a personal capacity. Further information can be found in the Company’s Form 6-K filed with the Securities and Exchange Commission (the “SEC”) on, May 21, 2025.

With the open market share purchases conducted in November 2025, the members of the Company’s Board of Directors and senior leadership team have in aggregate increased their positions in the Company’s shares by approximately 50% since May 2025.

Furthermore, the Company’s majority shareholder, Mudrick Capital Management, LP, informed the Company that it had increased its position by 350,000 shares via open-market purchases since November 24, 2025.

Furthermore, on November 19, 2025, Stephen Fitzpatrick filed a Schedule 13D/A with the SEC (the “SF 13D/A”) in relation to his beneficial ownership of the ordinary shares of the Company. Based on this filing and as confirmed by the Company’s share register issued by the Company’s transfer agent on November 28, 2025, the Company notes that as of the date of this filing, Mr. Fitzpatrick’s directly held shares represent less than 0.4% of the Company’s ordinary shares, down from approximately 15% on January 1, 2025.¹
