On September 11, 2026, Vertical Aerospace Ltd.

Such percentage of the voting power of the Voting Shares is based on the sum of (i) 168,640,928 Ordinary Shares issued and outstanding as of the Record Date (excluding treasury shares and earnout shares subject to voting restrictions), and (ii) 8,667,047 Ordinary Shares into which the 27,000 Series A Preferred Shares issued and oustanding as of the Record Date would have been convertible as of the Record Date, subject to a 4.99% beneficial ownership limitation. The Company’s shareholders of record as of the close of business on the Record Date are referred to herein as “Shareholders.”

A summary of the voting results at the AGM for each of the proposals is set forth below.

Proposal 1

The Shareholders ratified, by ordinary resolution, the appointment of PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026.

The voting results for such proposal were as follows:

Proposal 2

The Shareholders approved, by ordinary resolution, that the Vertical Aerospace Ltd. 2021 Incentive Award Plan (the “Plan”), be amended to increase the number of shares (or share-based instruments) permitted to be issued under the Plan to employees of the Company and its subsidiaries (excluding awards granted at any time to the Company’s Chief Executive Officer; or any Non-Employee Director) by 2,767,806 shares.

The voting results for such proposal were as follows:

Proposal 3

The Shareholders approved, by ordinary resolution, the amendment of the terms of certain outstanding option awards granted under the Plan to reduce the applicable exercise price from $3.50 or $5.82 per ordinary share, as applicable, to $1.30 per ordinary share.

The voting results for such proposal were as follows:

Proposal 4

The Shareholders approved, by special resolution, with immediate effect, the amendment and restatement of the Company’s fifth amended and restated memorandum and articles of association currently in effect (the “Articles”) in order to, among other matters, provide for certain director nomination rights, removal rights and consent rights for Mudrick Capital Management, L.P., the Company’s largest shareholder, by adopting a sixth amended and restated memorandum and articles of association (the “Sixth A&R M&A”).

The voting results for such proposal were as follows:

The Sixth A&R M&A became effective immediately upon its adoption by the Shareholders at the AGM, a copy of which is attached as Exhibit 3.1 hereto.

Proposal 5

Approval of the proposal to amend the Sixth A&R M&A to reflect the removal of certain references relating to Stephen Fitzpatrick, by adopting a seventh amended and restated memorandum and articles of association (the “Seventh A&R M&A”) called for each of (i) a special resolution of the Shareholders voting in favor thereof, and (ii) all shares held, directly or indirectly, by Stephen Fitzpatrick as at the Record Date being voted in favor thereof.

The voting results for such proposal were as follows:

Nevertheless, because all shares held, directly or indirectly, by Stephen Fitzpatrick as at the Record Date were not voted in favor thereof, such proposal was not approved. Accordingly, the Seventh A&R M&A was not adopted, and the Sixth A&R M&A, which became effective immediately upon its adoption at the AGM, remains in effect.
