Primary Market Bulletin 67

It flags a new National Storage Mechanism interface and planned 2027 changes, signalling that issuers and advisers should review document-filing workflows and controls now rather than at go-live. The bulletin also reports findings from the FCA's review of sponsors' AI use—an early supervisory signal that AI governance, human oversight, record-keeping and third-party risk management are moving onto the primary-markets agenda. Changes to Electronic Submission System profile updates will require named users and firms to check account administration and access controls.

The Knowledge Base consultation on consequential guidance updates gives firms an opportunity to shape practical guidance and test whether current processes remain aligned. For compliance teams, key actions are: assign ownership for NSM readiness, review AI use in sponsor and issuer-facing processes against existing governance and outsourcing expectations, update ESS user profiles and permissions, and assess draft guidance changes before responding. Impact is moderate: no immediate rule change, but clear supervisory direction and forthcoming operational changes.

Urgency is medium where firms rely on NSM/ESS or deploy AI in capital-markets workflows. Firms should avoid treating this as a purely administrative newsletter.
