FTSE 100 stocks open flat at 6,826 ahead of a UK third quarter GDP estimate update at 9.30am with most of the bigger movers at the small cap end of the market.
Shares in Constellation Healthcare (CHT:AIM) are up 34% at 250p after a 270p a share takeover while Fastjet (FJET:AIM) sinks 19% to 13p as the African airline signals the need for more capital from shareholders.
Constellation, which provides billing services to physicians in the US, has recommended the 270p a share offer to shareholders though is also allowed to look for other potential buyers until the deal is approved, according to a statement made to the stock market today. The deal, if completed, will mark the end of a short but successful venture for the business on AIM, which joined the market in December 2014 at 135p a share.
Moving the other way, Fastjet is down heavily this morning because of higher-than-expected costs incurred on a business turnaround plan which will mean shareholders are likely to need to provide more capital. Fastjet's need for new capital comes after a previous shareholder cash call only four months ago in July 2016 and chairman Colin Child is resigning as a result.
