A dedicated solution for registered securities in France
 

Euronext Securities continues to develop its post-trade capabilities while supporting compliance, operational efficiency, and market integration—thereby contributing to a stronger and more connected European capital market.

In this context, and as part of its European offering to be launched in September 2026, Euronext Securities has entered into a partnership with SLIB, a leading provider of software solutions, to support the management of French registered shares.

Together, the two companies are developing the Information on Registered Investors (IRI) platform, a SaaS solution designed for the benefit of the market.

Registered securities are a distinctive feature of the French market structure. French issuers must allow investors to hold their shares in different forms—bearer, pure registered, or administered registered—requiring structured information flows between the various market participants.

The platform will enable custodians, registrars, and issuers to manage all requirements related to registered securities in compliance with French regulations.
 

Standardising interactions between market participants

The new IRI platform will offer an innovative and modern approach to managing these interactions by enabling the exchange of IRI messages required by regulation between custodians and registrars, through standardised messaging formats, secure file transfers, and a user interface connected to market infrastructures.

The solution will also include dedicated reconciliation capabilities, enhanced monitoring of information flows, and a clear segregation of bearer and registered securities within securities accounts in Target2-Securities, ensuring consistency between issuer registers and custodian positions.

This partnership builds on SLIB’s strong connectivity with French market participants through its RegistrAccess platform, as well as its recognised expertise in serving the French post-trade ecosystem.

Together, Euronext Securities and SLIB aim to deliver a more standardised operating model, strengthen connectivity between registrars and custodians, and support the ongoing evolution of the French market within a broader European framework.

Recognised expertise, a shared ambition

Philippe Ruault, CEO says “We are very proud to support Euronext Securities in its ambitious development plan and to bring our expertise and existing software assets to further improve post-trade processing.”

Pierre Davoust, Head of Euronext Securities, said:
“Euronext Securities is delighted to partner with SLIB, a recognised player in the French market, to support the French Registered Shares framework for issuers, registrars and custodians. Together we are building the Information on Registered Investors platform to improve efficiency, strengthen connectivity and simplify the exchange of information across the ecosystem. SLIB was a natural partner given their deep expertise in the French post-trade market and their strong connectivity with market participants.”
