Numerous sources have reported that Rolls-Royce has ceased takeover talks with Finnish marine engine manufacturer Wärtsilä without reaching an acquisition deal.
Neither party disclosed why the talks broke down, nor quoted a monetary figure.
Industry analysts speculate that Rolls-Royce sought the entire company, with the services, manufacturing and design wings all consolidated into a handful of key interlinked assets.
The multi-billion-Euro Finnish company, with established footholds in the combustion engine, power plant and naval architecture and services markets, earned a tidy 480-million Euro profit (US$650 million) off sales of 4.7 billion Euros (US$6.4 billion) in 2012, but profits had begun to plateau over the past five years.
Elsewhere among Rolls-Royce's considerable portfolio, Tognum has been officially renamed Rolls-Royce Power Systems.
A wholly owned joint venture between Rolls-Royce and Daimler, which each own 50 per cent, Tognum was acquired in March 2013 and consolidated into the wider Rolls-Royce Group.
Tognum's largest subsidiary, MTU Friedrichshafen, retains some of its brand presence, with USA-based Tognum America and Singapore-based Tognum Asia to be re-branded as MTU America and MTU Asia, respectively. Subsidiary Bergen Engines, meanwhile, will be brought under the Rolls-Royce Power Systems moniker.
