Prospectuses 2026: what changes for issuers and investment banks

Key data

Companies going public or issuing debt on European regulated markets have so far faced a process of preparing prospectuses marked by documentary fragmentation and duplication of requirements depending on the type of investor. The Delegated Regulation (EU) 2026/1061, published on 13 August 2026 and applicable three days later, substantially changes that scheme by amending Delegated Regulation (EU) 2019/980.

The change is not cosmetic: the number of required annexes is reduced, documentation for non-equity securities is unified and the distinction between prospectuses for retail and wholesale investors in separate documents is eliminated. For legal and financial teams managing issuances, this translates into fewer working hours, less risk of inconsistencies between documents and a more agile approval process with the competent authorities.

What does this regulation establish?

Regulation 2026/1061 introduces the following specific changes to the previous regime of Regulation 2019/980:

The standardization of prospectus format and sequence by type of security is particularly relevant for investment banks that structure multiple issuances per year: it allows reuse of templates and internal workflows, reducing the marginal cost of each transaction.

Economic and operational impact

The impact of this regulation is primarily a reduction in legal and operational costs for those involved in the preparation and approval of prospectuses. The specific effects are:

• Fewer hours of legal advice: by unifying the registration document and securities note for non-equity securities, the need to prepare and maintain two separate parallel documents differentiated by investor type disappears.
• Faster approval process: competent authorities work with a standardized format, which reduces review iterations and response times.
• Savings in ESG compliance: the integration of ESG requirements without duplication prevents issuers from having to report the same information in different formats to comply with different European regulations simultaneously.
• Direct advantage for European green bond issuers: if the bond already complies with European green bond regulations, it is exempt from new disclosure obligations in the prospectus, eliminating a layer of documentary work.
• Greater legal certainty for new instruments: the flexibility granted to competent authorities to adapt requirements for financial instruments not covered in the annexes reduces the risk of regulatory blockages in innovative transactions.

Who does it affect?

• Securities-issuing companies that make public offerings or admission to trading on EU regulated markets.
• Investment banks acting as global coordinators or placing entities in fixed or variable income issuances.
• Legal advisers specializing in capital markets who prepare and review prospectuses.
• Issuers of compliant European green bonds that benefit from the exemption from new disclosure obligations.
• Capital market supervisory authorities (such as CNMV in Spain) that approve and examine prospectuses.
• Companies with innovative financial instruments not covered in the current annexes, which now have a more flexible framework.

Practical example

A Spanish energy sector company plans to issue corporate bonds (non-equity securities) on a European regulated market in September 2026. Under the previous regime of Regulation 2019/980, its legal team had to prepare differentiated registration documents for retail and wholesale investors, with the coordination, review and approval costs that entails.

With Regulation 2026/1061 applicable from 16 August 2026, the company prepares a single registration document and a single securities note that covers both investor profiles. The format follows the standardized sequence for that type of security, which facilitates review by CNMV. Furthermore, if the issuance is structured as a European green bond compliant with applicable EU regulations, the company is exempt from adding new ESG-specific disclosure sections to the prospectus, as that information is considered covered by the green bond framework.

The practical result: fewer weeks of legal work, lower risk of documentary inconsistencies and a more predictable approval process.

What should companies do now?

1. Review internal prospectus templates: legal and capital markets teams should update their documentary models to reflect the new standardized format and unified structure for non-equity securities.
2. Eliminate retail/wholesale duplication: if internal processes contemplate the preparation of separate documents by investor type, they should be simplified to a single document compliant with the new scheme.
3. Verify the ESG status of planned issuances: issuers with European green bonds should confirm whether their structure already complies with applicable EU regulations to benefit from the exemption from new disclosure obligations.
4. Coordinate with external legal advisers: update assignments and advisory budgets to reflect the reduction in documentary work resulting from the simplification.
5. Consult with the competent authority (CNMV in Spain): for issuances with innovative financial instruments not covered in the annexes, explore with the supervisory authority the flexibility available to adapt requirements.
6. Apply from 16 August 2026: the regulation is directly applicable from that date. Issuances in progress or planned after that date must comply with the new regime.
