EU Sanctions Against Iran 2026: What Companies Must Review

Key data

Companies with commercial or financial links to Iran have an immediate obligation: to review the corrected text of Regulation (EU) 2026/759, published on 23 April 2026. Although this is a corrigendum, the technical adjustments may modify the exact application of current restrictive measures, which directly affects regulatory compliance for any transaction with Iranian counterparties.

The corrected regulation modifies the sanctions framework established in Regulation (EU) No 267/2012 and repeals Regulation (EU) No 961/2010. Operating with an outdated interpretation of the text may constitute a breach, even if unintentional.

What does this regulation establish?

Regulation (EU) 2026/759 modifies the EU sanctions regime against Iran, whose basis is Regulation 267/2012. The corrigendum published on 23 April 2026 introduces technical adjustments that may have practical implications for the application of the following restrictive measures:

• Asset freezing linked to designated Iranian persons or entities.
• Transaction prohibitions with counterparties subject to sanctions.
• Trade restrictions on certain categories of goods, technology and services.

The repeal of Regulation 961/2010 was already included in the original text of 2026/759. The corrigendum does not introduce new sanctions, but may modify the exact wording of obligations, definitions or lists of designated entities, affecting how they are applied in practice.

Economic and operational impact

The impact is not theoretical. Technical corrections in sanctions regulations may modify the exact scope of prohibitions or the criteria for designating entities. Working with an outdated version of the text exposes companies to three concrete risks:

• Serious administrative sanctions for breach of the restrictive regime, even if the breach is unintentional.
• Criminal liability for directors and executives responsible for regulatory compliance.
• Operational blockade: financial entities may reject transactions or freeze accounts if they detect links with Iranian counterparties not verified against the current text.

The sectors with the greatest operational exposure are those that maintain ongoing commercial relationships with Iran: technology exporters, energy companies and financial entities managing assets or financing linked to Iranian counterparties.

Who does it affect?

This corrigendum is directly relevant to:

• Financial entities (banks, insurance companies, asset managers) that manage assets or conduct transactions with Iranian counterparties or entities linked to Iran.
• Technology exporters with operations towards Iran or with intermediary companies that may have Iranian links.
• Energy sector companies with contracts, assets or shareholdings linked to Iranian entities.
• Commercial companies with import or export activity to or from Iran.
• Legal and compliance advisors supporting any of the above.
• CFOs and financial directors responsible for validating counterparties and international transactions.

Practical example

A Spanish energy company maintains a supply contract with an entity based in a third country, but whose shareholding includes Iranian participation. Until now, the compliance team validated counterparties against the text of Regulation 267/2012 in its previous version.

With the publication of the corrigendum to Regulation 2026/759 on 23 April 2026, the exact wording of a definition, list of designated entities or application criterion may have changed. If the compliance team does not update its verification process with the corrected text, the company may be operating in breach without knowing it, with the consequent risk of serious administrative and criminal sanctions.

The concrete action: download the corrected text from the EU Official Journal, compare it with the previous version and update internal counterparty verification procedures.

What should companies do now?

1. Download the corrected text of Regulation (EU) 2026/759 from the EU Official Journal and compare it with the previous version to identify the exact technical changes introduced.
2. Review internal compliance procedures to verify that the lists of prohibited counterparties, asset freezing criteria and trade restrictions are applied in accordance with the corrected text.
3. Update counterparty verification checklists used by financial and operations teams to validate transactions with parties linked to Iran.
4. Inform responsible teams in export, finance and regulatory compliance about the existence of this corrigendum and the obligation to apply the current text.
5. Consult with specialized legal advisors if the company maintains active operations with Iranian counterparties or assets linked to designated entities, to assess whether the technical changes affect ongoing contracts or positions.
