Balfour has rejected two proposals by Carillion to create a £3bn group better placed to compete for major international contracts against the likes of Spain’s Ferrovial.
The two companies revealed they were in talks last month, but Balfour walked away only days later after Carillion insisted it cancel the planned sale of its US engineering and design business Parsons Brinckerhoff.
Since then the companies have been engaged in a battle of statements and counter-statements, with Balfour continuing to argue that Carillion’s proposals will fail to deliver as much value to shareholders as it can as an independent company.
Under takeover rules Carillion has until August 21 to make a final offer.
Balfour Beatty said today it had further considered yesterday’s announcement from Carillion, and continued to reject its suitor’s assessment of potential cost savings.
“The proposal remains unchanged to that rejected on August 11 2014. The board reaffirms its rejection of the proposal,” Balfour said in its statement.
Balfour said it believed the proposal involved reducing its British construction revenues by up to two thirds and that that would in turn reduce the potential synergies available.
Carillion has said it could save more than £175m a year by the end of 2016, more than some analysts expected, by streamlining offices, supply chains and IT.
“Cost savings driven by shrinking the business should not be confused with synergies,” Balfour said.
Balfour also said that any shrinking of its British construction business as part of a merged group would deny shareholders the benefits from a recovery in that sector, signs of which it was already seeing.
The approach from Carillion in July followed a difficult 18 months for Balfour Beatty, which has had a series of profit warnings and lost its chief executive Andrew McNaughton in May. Its shares have slumped 22 per cent over the last six months.
“Carillion’s approach for the entire group at this stage of the construction cycle is opportunistic,” Balfour said in its statement.
