Corrected securities prospectus: what changes for issuers and advisors in 2026

Key data

Companies planning to raise capital in European markets—whether through a stock market listing, capital increase or debt issuance—are required to prepare a standardized prospectus. The correction published on November 3, 2026 corrects Delegated Regulation (EU) 2026/1061, which in turn amended Delegated Regulation (EU) 2019/980, the reference standard on the format of these documents.

This is not a minor wording change: the correction directly impacts the standardized format of the prospectus, the order in which information must be presented and the examination and approval procedures by national and European supervisory authorities. Any prospectus model prepared with the previous version of Delegated Regulation (EU) 2026/1061—published on August 13, 2026—must be reviewed in light of this correction.

What does this regulation establish?

The prospectus is the legal and financial document that every company must prepare and submit for regulatory approval before making a public offering of securities or requesting admission to trading on a European regulated market. Its content, structure and format are harmonized at European level to ensure that investors receive comparable and sufficient information.

The regulatory chain affected is as follows:

The three specific elements affected by the correction are:

• Standardized prospectus format: the formal structure of the document that issuers must present.
• Standardized information order: the sequence in which content blocks must appear within the prospectus.
• Examination and approval procedures: the steps and requirements that both issuers and supervisory authorities must follow to validate the document.

Economic and operational impact

The impact is not of a direct sanctioning nature, but rather operational and risk of delay. A prospectus that does not comply with the corrected version of the regulation may be rejected by the competent supervisory authority—in Spain, the CNMV—or may require corrections that delay the operation timeline.

In capital market operations, delays have real and measurable costs:

• Market windows are limited: a delay of weeks may force postponing an operation for months.
• Legal and financial teams (investment banks, advisors, auditors) bill by time: any additional iteration on the prospectus translates into hours of advisory work.
• In debt issuances, a delay may coincide with an adverse movement in interest rates, increasing financing costs.

Companies and their advisors who already had prospectus models prepared under Delegated Regulation (EU) 2026/1061—published on August 13, 2026—must now compare those models with the corrected version to identify whether any of the three affected elements (format, order, procedures) require adjustment.

Who does it affect?

• Securities-issuing companies: any company planning a public offering of shares (IPO or capital increase) or issuance of bonds or other securities on European regulated markets.
• Investment banks: the coordinators and financial advisors of operations, responsible for structuring the prospectus together with the issuer.
• Legal advisors: law firms that draft and review the legal content of the prospectus and coordinate the regulatory approval process.
• Market supervisory authorities: bodies such as the CNMV in Spain, the AMF in France or BaFin in Germany, which must apply the updated examination and approval procedures.

Practical example

A Spanish industrial company has planned a capital increase in the fourth quarter of 2026 to finance an acquisition. Its legal advisor had prepared a prospectus draft based on Delegated Regulation (EU) 2026/1061 published in August 2026.

With the publication of this correction on November 3, 2026, the legal team must review that draft in three specific points: whether the standardized format of the document remains correct, whether the information order respects the corrected sequence, and whether the approval procedures planned with the CNMV remain applicable. If any deviation is detected, the draft must be updated before submission to the regulator to avoid correction requests that delay the operation.

What should companies do now?

1. Identify if there is an ongoing or planned capital market operation: if the company has planned an IPO, capital increase or debt issuance on European markets, this correction is directly relevant.
2. Review existing prospectus drafts: compare any model or draft prepared under Delegated Regulation (EU) 2026/1061 (August 2026) with the corrected version published on November 3, 2026, verifying the three affected elements: format, information order and approval procedures.
3. Coordinate with legal advisor and investment bank: communicate the existence of this correction to external teams managing the prospectus process so they update their templates and working models.
4. Consult with the competent supervisory authority: if the operation is in an advanced phase, verify with the CNMV (or equivalent body) whether the examination and approval procedures have changed and what the applicable timeline is.
5. Update internal templates: companies with recurring issuance programs (such as note programs or bonds) should update their base prospectus models to reflect the corrected version.
