RE: Carnival still listed on UK?19 May 2026 18:58
According to Gemini....
While there is no fixed legal deadline, UK brokers are authorized and regulated by the Financial Conduct Authority (FCA). Under the FCA's Consumer Duty rules and standard business principles, brokers are required to act:
With due skill, care, and diligence.
In a way that delivers good outcomes for retail customers.
On a "best efforts" basis to process mandatory corporate actions in a timely manner.
If a broker takes an unreasonable amount of time compared to its competitors (e.g., if one UK broker processed it in 3 days, but yours is stretching into weeks without explanation), they may be failing their regulatory duty to provide a proper standard of service.
What You Should Do Right Now
Check the "Corporate Actions" or Messages Tab: Brokers usually post a specific notification detailing their estimated timeline for complex international unifications.
Demand a Timeline via Support: Send a formal message to your broker. Do not just ask "where are my shares?" Ask for specifics: "Regarding the Carnival plc unification on May 7, has your sub-custodian received the NYSE line from the DTCC, and what is your specific target date for allocation?" This forces them to give you a definitive internal status report rather than a generic template response.
Log a Formal Complaint: If you are missing out on an opportunity to sell and the delay is causing you financial friction, ask your broker to open a formal complaint. In the UK, opening a formal complaint triggers a strict regulatory clock—they must provide a final response within 8 weeks. If their delay was due to negligence or a system failure on their part, you can later escalate the case to the Financial Ombudsman Service (FOS) to claim compensation for financial loss.
