LONDON -- Aston Martin's biggest investor, Strategic European Investment Group, part of the Italian private equity group Investindustrial, offered to buy another 3 percent stake in the automaker, whose shares have slumped since listing last year.
The group already owns 31 percent of Aston Martin. It only wants to buy a maximum 3 percent more but has to make an offer to all shareholders due to the size of its existing holding.
The group confirmed it is offering to pay 10 pounds ($12.53) per share.
Aston Martin has struggled since it listed in October last year. Its shares, down 21 percent so far this year, closed Thursday at 963 pence, valuing the business at 2.18 billion pounds.
The company's recent results have been hit by a need to invest more in its manufacturing plants and expand its vehicle offering, leading to higher costs.
