This base prospectus supplement (the "Supplement") is supplemental to, forms part of and must be read in conjunction with, the base prospectus dated 24 February 2026 (the "Base Prospectus") prepared by Barclays PLC (the "Issuer") with respect to its Debt Issuance Programme (the "Programme"). This Supplement constitutes a supplementary prospectus in respect of the Base Prospectus for the Issuer in compliance with PRM 10 of the Financial Conduct Authority (the "FCA") Handbook Prospectus Rules: Admission to Trading on a Regulated Market sourcebook (the "PRM") made in accordance with the Public Offers and Admissions to Trading Regulations 2024 (the "POATRs", together with the PRM, the "UK Prospectus Regime").

Terms defined in the Base Prospectus shall, unless the context otherwise requires, have the same meaning when used in this Supplement.

This Supplement has been approved by the FCA. The FCA only approves this Supplement as meeting the standards of completeness, comprehensibility and consistency imposed by the rules in the PRM. Such approval should not be considered as an endorsement of the Issuer that is the subject of this Supplement. With effect from the date of this Supplement the information appearing in, or incorporated by reference into, the Base Prospectus shall be supplemented in the manner described below.

This Supplement constitutes supplementary admission particulars in respect of the Base Prospectus for the purposes of the Rulebook of International Securities Market of the London Stock Exchange.

The purpose of this Supplement is to:

(a) supplement the section entitled "Information Incorporated by Reference" commencing on page 29 of the Base Prospectus and incorporate by reference into the Base Prospectus the unaudited Q1 2026 Results Announcement of the Issuer, as filed with the SEC on Form 6-K (including exhibits thereto) on 28 April 2026 in respect of the three months ended 31 March 2026 (the "Q1 2026 Results Announcement"). The Q1 2026 Results Announcement has been filed with the FCA and shall be deemed to be incorporated in, and form part of, the Base Prospectus as supplemented by this Supplement. The Q1 2026 Results Announcement may be inspected during normal business hours at Barclays Treasury, 1 Churchill Place, London, E14 5HP, United Kingdom and at the specified office of the Principal Paying Agent, at 160 Queen Victoria Street, London, EC4V 4LA, United Kingdom during the life of the Notes issued pursuant to the Base Prospectus. It has also been filed with the SEC and is available in electronic form on the SEC's website at https://www.sec.gov/cgi-bin/browse-edgar?company=barclays+plc&owner=exclude&action=getcompany;

(b) amend the second paragraph of the section entitled "Forward-Looking Statements" commencing on page viii of the Base Prospectus by replacing it with the following:

---

"Forward-looking statements speak only as at the date on which they are made. Forward-looking statements may be affected by a number of factors, including, without limitation: changes in legislation, regulations, governmental and regulatory policies, expectations and actions, voluntary codes of practices and the interpretation thereof, changes in IFRS and other accounting standards, including practices with regard to the interpretation and application thereof and emerging and developing sustainability reporting standards (including emissions accounting methodologies); changes in tax laws and practice; the outcome of current and future legal proceedings and regulatory investigations; the Group's ability along with governments and other stakeholders to measure, manage and mitigate the impacts of climate change effectively or navigate inconsistencies and conflicts in the manner in which climate policy is implemented in the regions where the Group operates, including as a result of the adoption of rules and regulations taking a different or opposing position on sustainability matters, or other forms of governmental and regulatory action against sustainability policies; environmental, social and geopolitical risks and incidents and similar events beyond the Group's control; financial crime; the impact of competition in the banking and financial services industry; capital, liquidity, leverage and other regulatory rules and requirements applicable to past, current and future periods; UK, the United States ("U.S."), Eurozone and global macroeconomic and business conditions, including inflation; volatility in credit and capital markets; market related risks such as changes in interest rates and foreign exchange rates; reforms to benchmark interest rates and indices; higher or lower asset valuations; changes in credit ratings of any entity within the Group or any securities issued by it; changes in counterparty risk; changes in consumer behaviour; changes in trade policy, including the imposition of tariffs or other protectionist measures; the direct and indirect consequences of the conflicts in the Middle East and Ukraine on European and global macroeconomic conditions, political stability and financial markets; changes in U.S. legislation and policy; developments in the UK's relationship with the European Union (the "EU"); the risk of cyberattacks, information or security breaches, technology failures or operational disruptions and any subsequent impact on the Group's reputation, business or operations; the use of new technology, including artificial intelligence; the Group's ability to access funding; and the success of acquisitions, disposals, joint ventures and other strategic transactions. A number of these factors are beyond the Group's control. As a result, the Group's actual financial position, results, financial and non-financial metrics or performance measures or its ability to meet commitments and targets may differ materially from the statements or guidance set forth in the Group's forward-looking statements. In setting its targets and outlook for the period 2026-2028, the Group has made certain assumptions about the macroeconomic environment, including, without limitation, inflation, interest and unemployment rates, the different markets and competitive conditions in which the Group operates, and its ability to grow certain businesses and achieve costs savings and other structural actions. Additional risks and factors which may impact the Group's future financial condition and performance are identified in the Issuer's filings with the SEC (including, without limitation, in the 2025 Annual Report (as defined in the "Information Incorporated by Reference" section below)) which are available on the SEC's website at www.sec.gov."
