FTSE 100 firm Hanson has brought in Financial Dynamics as takeover speculation swirls around the British building materials company.
The firm has enjoyed a recent share-price boost as rumours mount about a bid from Mexican rival Cemex.
FD was brought in at the start of the month following a four-way pitch, replacing incumbent Maitland. The agency's financial comms practice chairman, Andrew Lorenz, heads the account.
One of FD's challenges will be dealing with the asbestos claims that still haunt the firm. In August it said it incurred £13m of costs from claims related to its US activity. Some analysts have said it may look to dispose of these liabilities.
The speculation around Hanson's future follows a period of consolidation within the building-materials industry. Last year Cemex acquired another British company, RMC Group, for £2.3bn.
After its own days as a conglomerate, Hanson was split into four companies - Millennium Chemicals, Imperial Tobacco, Energy Group and Hanson - in 1995.
