SHARES in bus and train operator FirstGroup, whose chief executive is Moir Lockhead, right, rose 3% yesterday as it announced that its offer for GB Railways had received 69.7% acceptances. The offer was extended for a further seven days. FirstGroup announced in mid-July that it is offering an initial 250p-a-share cash bid for GB, which would value the Anglia and Hull Trains operator at (pounds) 22m. FirstGroup will pay a further 200p per share if GB Rail succeeds in its bid for the Greater Anglia franchise, from which FirstGroup was excluded in April when it failed to make the Strategic Rail Authority's shortlist. FirstGroup shares closed up 8.5p at 284p.
