City workers in Paternoster Square, where the headquarters of the London Stock Exchange is based, in the City of London, UK, on Thursday, March 2, 2023.
British chip designer Arm, owned by Japan's SoftBank, and building materials group CRH intend to shun London and pursue stock market listings in the U.S., dealing a blow to the U.K.'s post-Brexit vision.
Arm said in a statement Friday that it was seeking to pursue a U.S.-only listing this year.
It comes shortly after CRH, one of the FTSE 100 's biggest companies, said it plans to move its primary stock market listing to New York.
The news is likely to bolster fears that the U.K. stock market is losing out to international rivals.
