Primary Market Bulletin 59: FCA Observations on the Delayed Disclosure of Inside Information and Other Matters
The FCA published Primary Market Bulletin 59 on 23 October 2025, with key messages on compliance with disclosure obligations, corporate treasury strategy in relation to cryptoassets, a review of the short selling regime, and changes to the National Storage Mechanism.
Delayed Disclosure of Inside Information (DDII) under UK MAR
The FCA reviewed issuer compliance with delayed disclosure requirements under Article 17(4) UK MAR, which allows delayed public disclosure of inside information under certain conditions, against the findings of its previous review carried out in November 2020. It found:
- a 39% decrease in DDII notifications submitted per day since its previous review;
- approximately 18% of issuers on the trading venues reviewed made DDII notifications, compared to 25% previously; and
- average delays increased by 7 days (since the previous review) to 35.2 days.
While the FCA noted that the fewer DDII notifications and longer delays of disclosures did not necessarily mean that the level of compliance had fallen, it reinforced the importance of having appropriate arrangements in place to ensure compliance.
As a reminder, inside information may only be delayed if (i) immediate disclosure would prejudice the legitimate interests of the issuer or its group, (ii) the delay of the disclosure would not mislead the public, and (iii) the confidentiality of that information can be ensured. The issue must also, immediately after announcement of such inside information, notify the FCA of the delay.
Enhancing the National Storage Mechanism (NSM)
- As highlighted in our previous edition, the FCA is introducing important changes to the NSM, effective from 3 November 2025.
- From this date, updated metadata requirements will apply when submitting disclosures to the FCA’s NSM via the Electronic Submission System (ESS) or a Primary Information Provider.
- Issuers must ensure their Legal Entity Identifier (LEI) is current, and that metadata for disclosures is complete, correct, and up to date (including for referenced entities).
The bulletin also sets out a number of reminders to listed companies who are acquiring or have plans to acquire cryptoassets for the purpose of long-term value appreciation as part of their treasury management strategy, and the FCA's intention to publish a consultation paper setting out its proposals to support changes to the regulations on short selling made by the Short Selling Regulations 2025.
Key actions for listed companies:
- Review and reinforce policies and procedures for delayed disclosure, ensuring that decisions to delay disclosure meet all conditions of Article 17(4) of UK MAR and are fully documented and arrange training for relevant staff.
- If exploring or adopting a cryptoasset treasury strategy, assess materiality under the UKLR/UK MAR, prepare for heightened disclosures, and seek advice where necessary on transaction classification.
- Review internal checklists and procedures to ascertain whether they need to be updated to align with new NSM submission protocols and supporting materials and ensure all regulatory filings from 3 November 2025 use updated NSM/ESS templates and metadata.
