Much has been made of the ‘parlous’ state of the UK’s IPO market of late. Some commentators have described the US listings of companies such as ARM and CRH as ‘blows’ to London, citing better valuations and liquidity prospects in the US, together with the UK’s complex and expensive regime, as key reasons to look Stateside. But companies looking to list should exercise caution. The US is not suitable for all companies, especially those with a smaller market cap who could fail to make even the smallest of ripples across the pond.
