Spotless's remaining shareholders are not expected to cause Downer EDI "any dramas" after the contractor ended its $1.2 billion takeover of the services group just shy of the critical 90 per cent level, chief executive Grant Fenn said.

Downer controls 87.8 per cent of Spotless after its takeover offer closed on Monday night, with New York hedge fund Coltrane Asset Management – which owns 10.6 per cent – and about 1000 retail shareholders refusing to accept its bid of $1.15 per share in cash.
