Investment banking group Close Brothers said talks with potential bidders for the company have ended.
In a statement, Close Brothers said it had held 'detailed discussions with several parties,' but that the negotiations were now over. Shares fell 68p, or 9%, to 682 pence.
The company received a £1.5 billion joint takeover offer from UK stockbroker Cenkos Securities and Icelandic bank Landsbanki in January, which was later withdrawn.
The group also received approaches from other suitors, reported in the press to include US buyout firm Blackstone and rival UK investment bank Collins Stewart.
Close Brothers reports its half-year results on Monday.
