4basebio Plc - Director Dealing
Director's Dealing Classification · 85% confidence The document is an announcement that Dr. Amy Walker, a director and CEO, has acquired ordinary shares and includes the required Notification of Dealing table and details. This matches the definition of a Director’s Dealing (insider share transaction) rather than a company share buyback or other filing. Therefore, it should be classified as DIRS.

4basebio Plc - Final Results and Notice of AGM
Earnings Release Classification · 92% confidence The document is a press‐style announcement dated 20 May 2026, titled “Final Results and Notice of AGM,” presenting audited financial highlights (revenue, loss, cash), operational highlights, post‐period events, and CEO/Chair commentary for the year ended 31 December 2025. It is an initial summary release of annual results, not the full Annual Report (which is stated to follow), and is formatted as a results announcement rather than a complete 10-K/AR. This aligns with an Earnings Release (ER) under the taxonomy. Therefore, it is classified as ER. FY 2025
