Nabarro Nathanson has completed its fourteenth AIM flotation of 2006, with a combined value of £513m, following two successful IPOs completed last week.
The firm saw real estate-related companies Ciref and Summit Germany float on AIM with market capitalisations of £50m and £60m respectively.
Corporate partner Iain Newman, lead adviser for Summit Germany, said the firm had averaged around 20 AIM IPOs each year and that the buoyant market had kept corporate partners busy throughout the first quarter.
"The first few months have been a lot more frenetic than usual, mainly because the market was very good, up until [a fortnight ago]," said Newman. "We do both sides of the deal, or act for the Nomads [nominated advisers] direct, and we've secured all these mandates through existing contacts or through personal relationships that have led to the mandate."
The firm has represented companies from Europe, China and the US, as well as the UK, in the technology, resources, alternative energy and real estate sectors.
Other companies listed on AIM by the firm this year include O Twelve Estates, which listed with a market capitalisation of £122.5m, Camco International (£83m) and Oxford Catalysts (£65m).
Nabarros' emphasis on AIM work has been boosted by the addition of partner Clare Grayston, who joined the firm in January from Lewis Silkin.
"Having Clare on board has certainly added to the depth of our offering, which helps tremendously," said Newman.
