The rights issue is expected to raise around £13.4m, adding to the company’s market capitalisation of approximately £29m.
Grandfield MD Marc Popiolek leads the account and reports to Hampson finance director Howard Kimberley.
The agency has been briefed to handle media and analyst relations during the offering. It will also convey the corporate repositioning of Hampson as a company that has survived the post-11 September 2001 aviation downturn.
Hampson won a £207m contract with US private jet maker Eclipse Aviation in December.
‘We’re now seeing significant opportunities in our core markets. With this in mind we feel it appropriate to develop a more cogent and coherent investor relations strategy,’ said Kimberley.
He added that Grandfield will communicate an ‘evolutionary change’ in Hampson’s business.
The money raised from the IPO will be used to pay off debt, expand capacity in the turbocharger sector and establish a low-cost supply source in Asia.
Hampson used Buchanan Communications until it took PR in-house two years ago to cut costs.
