Santander UK Releases FCA-Approved Supplementary Prospectus for €30 Billion Euro Medium Term Note Programme

Overview of Santander UK's €30 Billion Euro Medium Term Note Programme and Funding Strategy

Santander UK, one of the UK's largest banking franchises, serves retail, commercial, and corporate customers through extensive branch networks and digital platforms. Its €30 billion Euro Medium Term Note Programme is a pivotal element of the group’s wholesale funding strategy, facilitating capital market access across various currencies and regions. This programme enables Santander UK to issue debt securities within a regulated framework overseen by the UK Financial Conduct Authority, granting flexibility to meet funding needs while adhering to UK regulatory standards and capital adequacy requirements.

Such medium-term note programmes are standard among leading European banks, allowing efficient access to wholesale markets. The €30 billion programme size underscores Santander UK's scale and creditworthiness in European debt markets. Maintaining an up-to-date, FCA-approved prospectus ensures investors receive timely and accurate information prior to any securities issuance. Supplementary prospectuses serve to transparently communicate material developments and regulatory updates to the market.

FCA Approval and Regulatory Oversight of the July 2026 Supplementary Prospectus

The supplementary prospectus dated 22 July 2026 has been formally approved by the UK Financial Conduct Authority, the principal regulator for UK banking and capital markets. This mandatory approval process guarantees that disclosure documents comply with stringent standards for accuracy, completeness, and investor protection under the UK prospectus regime. FCA approval confirms that the document provides all necessary information for informed investment decisions.

The announcement does not specify the exact updates included, leaving investors unable to determine the precise nature of changes since the prior amendments on 1 May and 5 June 2026. Typically, supplementary prospectuses reflect regulatory changes, market developments, or newly identified material information. This third amendment to the April 2026 prospectus indicates ongoing refinement of the programme's terms and conditions.

Multiple Prospectus Updates Throughout 2026

Santander UK's Euro Medium Term Note Programme prospectus has been updated multiple times in 2026: initially dated 1 April, followed by supplements on 1 May, 5 June, and now 22 July. These frequent updates likely respond to evolving market conditions, regulatory requirements, or operational adjustments. Specific reasons for each amendment were not disclosed in this announcement.

This sequence of updates demonstrates Santander UK's active management of disclosure obligations related to its funding programme. Regular FCA-approved prospectus revisions are common among large financial institutions with significant wholesale funding activities, reflecting the dynamic regulatory and market environment.

Investor Access to Prospectus Documents and Communication Channels

The supplementary prospectus is publicly available through several authorized platforms, ensuring broad investor access. It can be retrieved via the London Stock Exchange’s RNS PDF service, the National Storage Mechanism (NSM), and Santander UK's investor relations website at https://www.santander.co.uk/about-santander/investor-relations/euro-medium-term-note-programme. This multi-channel availability facilitates transparency and ease of access for professional and retail investors alike.

Furthermore, Santander UK provides contact details for its Funding, Asset Rotation, and Investor Relations team at its London headquarters (2 Triton Square, Regent's Place), enabling investors to request further information or clarification regarding the programme. These measures reflect best practices in investor relations and regulatory compliance.

Territorial Restrictions and Geographic Limitations of the Programme

The prospectus includes territorial restrictions limiting the offering and sale of securities to residents of specified jurisdictions. The announcement highlights disclaimers clarifying that securities are not offered or sold outside these designated areas. Such restrictions align with regulatory mandates and issuer market strategies.

Notably, the United States market is excluded; the securities are not registered under the U.S. Securities Act of 1933 and cannot be offered or sold to U.S. persons as defined by Regulation S. This standard exclusion avoids the complexities of SEC registration and compliance with U.S. securities laws, ensuring offerings comply with applicable jurisdictional regulations.

Santander UK's Role Within Santander Group's Global Funding Framework

Santander UK Group Holdings plc functions as the UK arm of the Spanish multinational Santander Group. The UK operations form a key part of Santander’s European presence, serving millions across retail, commercial, and corporate sectors. The €30 billion funding programme reflects Santander UK's significant capital demands and its role as a critical funding conduit for the broader group. Access to wholesale capital markets via this programme supports liquidity, lending activities, and regulatory capital compliance.

Issuing euro-denominated debt securities enables Santander UK to tap into the extensive European institutional investor base. Maintaining a large, actively managed programme allows the bank to respond flexibly to funding requirements driven by lending growth and regulatory obligations. The programme’s success depends on ongoing prospectus updates, FCA approvals, and investor confidence in transparent disclosures.

Regulatory Framework Under FCA Prospectus Rules for Banking Funding Programmes

The release of the supplementary prospectus aligns with the UK’s robust regulatory regime governing securities offerings and prospectus disclosures. FCA rules mandate approval of all prospectuses and supplements, ensuring compliance with technical and substantive standards. The FCA’s endorsement confirms the document’s completeness and material accuracy for investor protection.

Given banks’ systemic importance, prospectus requirements are especially rigorous, demanding detailed disclosures on financial health, capital adequacy, liquidity, risk management, and regulatory compliance. Supplementary prospectuses are required to reflect material changes, ensuring investors have current data. Santander UK’s adherence to these standards highlights its commitment to transparent market communication and regulatory cooperation.

National Storage Mechanism Filing and Document Accessibility

Filing the supplementary prospectus with the National Storage Mechanism (NSM) fulfills European regulatory mandates for centralized storage and accessibility of prospectus documents. The NSM serves as the authorized repository within the European Economic Area, providing investors, market participants, and regulators with a single source for up-to-date prospectus information. The document will soon be accessible via the FCA’s NSM portal (https://data.fca.org.uk/#/nsm/nationalstoragemechanism).

This centralized filing reduces risks of outdated or inaccurate documents circulating and supports regulatory oversight. The NSM maintains a comprehensive record of all prospectus publications, enhancing market integrity and investor protection. Santander UK’s compliance with NSM requirements exemplifies adherence to international best practices in securities issuance.

Investment Considerations for Santander UK Debt Security Holders

The supplementary prospectus offers updated, FCA-approved information for current and prospective investors in Santander UK’s Euro Medium Term Note Programme. Existing noteholders gain access to the latest disclosures to monitor their investments effectively. The prospectus framework ensures comprehensive risk, financial, and business information relevant to the issuer’s debt servicing capacity.

Prospective investors can utilize the supplementary prospectus to assess creditworthiness, business outlook, and risk factors before acquiring notes. While immediate share price effects were not disclosed, routine prospectus updates are generally viewed positively, signaling issuer commitment to regulatory compliance and transparent capital market engagement. Investors are advised to review the supplementary prospectus alongside prior versions to identify any significant amendments.
