Eos Energy Enterprises, Inc.

Eos Energy Enterprises, Inc. completed its transition to the public markets in late 2020 through a business combination with B. Riley Principal 150 Merger Corp, the blank-check vehicle trading under ticker BMRG and sponsored by B. Riley Financial, Inc. The S-1/A amendment filed on November 13, 2020 supported registration of shares in connection with that merger, which brought Eos Energy — a U.S.-based developer of zinc-based long-duration battery energy storage systems — onto the Nasdaq under the ticker EOSE. The SPAC was formed and completed its IPO in 2020, targeting the clean energy and energy storage sector.
