The A123 Systems IPO: Signed, Sealed ... But Not Yet Delivered

Two unnamed sources with close ties to A123 Systems, the Watertown maker of next-gen lithium ion batteries for Black and Decker cordless tools and plug-in hybrid cars, tell me that the company's IPO filing is essentially complete. Once the first quarter numbers are finalized, an S-1 is likely to arrive in the SEC's inbox sometime in the next month or so. The offering could value the company at more than $1 billion. Road show is planned for September; Goldman, JP Morgan, and Merrill are underwriting, I'm told.

A123 Systems has raised more than $150 million since it was founded in 2001. Among the biggest winners from a successful IPO would be North Bridge Venture Partners and Sycamore Networks chairman Desh Deshpande. (North Bridge has a cool video case study on A123.) Sequoia Capital and General Electric are also investors.

Will Wall Street have an appetite for a battery IPO in September? We'll see...

A123 Systems' PR rep, Keith Watson, says, "The company can't comment on anything related to an IPO."
