Aston Martin has lowered maximum price for the initial public offering, valuing the group at £4.5 billion.
The luxury carmaker has cut its target price to between £18 and £20 per share, from the previous £17.50 to £22 per share.
Despite the reduction in price, shareholders remain optimistic. The private equity firm, Invest Industrial, bought a 37.5 percent stake in 2012, when Aston Martin was valued about £400 million.
Carmakers are expected to be hit hardest when the UK crashes out of the EU in just five months time.
Aston Martin’s chief executive Andy Palmer said last month that Aston is “well insulated” from problems that could lead to the UK leaving the EU without a trade deal.
“We can demonstrate that Brexit is not a major effect for us,” he said.
“If there is a tariff into Europe, it’s countered by a tariff into the UK for our competitors so you might lose a little bit of market share in the EU but you pick it up in the UK.”
Aston Martin has contingency plans to close the Warwickshire plant for nine days following Brexit if there is no deal.
The company has been performing strongly, selling 5,098 cars last year – its highest number in nine years.
Demand for the luxury cars is also growing in China, where the group hope to open 10 new showrooms.
Greg Clark, the secretary of state for business, energy and industrial strategy, said: “Aston Martin is an iconic brand that is an integral part of Britain’s proud automotive heritage.”
“Through our modern industrial strategy we are building on this success, and the new Vantage is a British-built car exemplifying the skill and innovation that sets the UK auto sector apart from its competitors.”
