Although new IPOs continue apace, there are a few cracks appearing. Two companies have today scrapped their planned listings. Israeli digital advertising group Matomy Media has decided not to join the main market, saying it couldn't meet the requirements to qualify for a Premium Listing, namely having at least 25% of shares held by investors in the European Economic Area. It says investor interest was too broad, geographically. Subscription TV channel operator Nation Media has binned its Aim listing after numerous delays. Former Sky finance boss Richard Brooke has quit as chairman which may have diluted the Box Nation broadcaster's attraction to potential investors.
