Aspen Aerogels, which manufactures high-performance aerogel insulation used in large energy facilities, filed on Monday with the SEC to raise up to $86 million in an initial public offering. It originally filed for a $115 million IPO in June 2011, but withdrew its plans in May 2013. The Northborough, MA-based company, which was founded in 2001 and booked $86 million in sales for the fiscal year ended December 31, 2013, plans to list on the NYSE under the symbol ASPN. Aspen Aerogels initially filed confidentially on March 25, 2014. Barclays, J.P. Morgan and Citi are the joint bookrunners on the deal. No pricing terms were disclosed.
