Eos Energy Enterprises Inc., a manufacturer of large power storage systems, began trading Nov. 17 as a public company on the Nasdaq Capital Market. The listing became effective with the completion the previous day of a merger between the Edison-based company and a special purpose acquisition company formed by B. Riley Financial Inc., which was announced in June. At the time, the companies said the deal valued Eos at $290 million and would provide about $225 million in new equity financing. To celebrate the listing, Eos Chief Executive Officer Joe Mastrangelo rang the virtual opening bell for the Nasdaq. In this special edition of NJBIZ Conversations, Editor Jeff Kanige spoke with Mastrangelo after the ceremony about the company’s plans. Watch the full interview here.
