The Group’s
statutory accounts for the year ended December 31, 2025 have been reported on by the Company’s auditor, but not yet delivered to the Registrar of Companies. The report of the auditor was (i) unqualified and (ii) did not include

2. Material accounting policies
Basis of preparation
The unaudited condensed consolidated financial statements (the “financial statements”) for the three months ended March 31,
2026 have been prepared in accordance with International Accounting Standard 34, “Interim Financial Reporting” (“IAS 34”). The material accounting policies and methods of computation applied in the preparation of the
financial statements are consistent with those applied in the Company’s annual financial statements for the year ended December 31, 2025. No new standards, amendments or interpretations have had an impact on the financial statements for
the three months ended March 31, 2026. The financial statements comprise the financial statements of the Group at March 31, 2026. The financial statements are presented in pounds sterling, which is also the Company’s functional
currency. All values are rounded to the nearest thousand, except where otherwise indicated.
The financial statements do not include all
the information and disclosures required in the annual financial statements, and should be read in conjunction with the Company’s annual financial statements for the year ended December 31, 2025.
In the opinion of management, these unaudited condensed consolidated financial statements include all normal recurring adjustments necessary
for a fair statement of the results of operations, financial position and cash flows. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results that can be expected for the Company’s
fiscal year ending December 31, 2026.
Going concern
The Company’s consolidated financial statements have been presented on the basis that it is a going concern. The Company has not
generated any revenues from operations to date and does not expect to in the foreseeable future. As such, the Company has incurred recurring net losses, has an accumulated deficit totaling £251.2 million and cash flows used in operating
activities of £3.2 million as of and for the three months ended March 31, 2026. The Company had £21.5 million of cash and cash equivalents at March 31, 2026.
In reviewing the going concern assessment the Company’s board of directors have considered a going concern period of 12-months from the issuance of these financial statements. Based on its current operating budgets and development plans, the Company’s cash and cash equivalents on hand will be sufficient to fund its
anticipated operations for the entirety of the going concern assessment period. The board of directors is therefore satisfied that it is appropriate to adopt the going concern basis of accounting in preparing the financial statements.
