ERock filed paperwork on Friday for a proposed initial public offering on the New York Stock Exchange, the company said in a statement.
The business presents itself as a vertically integrated designer, installer, operator and maintainer of multi-purpose distributed power systems that rely on proprietary natural gas generators and embedded software. ERock says its systems are engineered to be deployed at scale exceeding 1 gigawatt and are configured to serve three distinct use cases: bridge power, backup power, and dispatchable power.
ERock identified data centers, utilities and large commercial and industrial customers as its primary end markets. The company reports operations in nine U.S. states with a concentration of activity in California and Texas. It cites more than 15 years of operational experience and states it has deployed in excess of 2,000 units across roughly 400 operational sites.
As of March 31, 2026, ERock says its installed base totals approximately 1,000 megawatts. The company also disclosed a contracted power system sales backlog of about $1.3 billion.
On the transaction side, Morgan Stanley and J.P. Morgan are listed as lead underwriters for the offering. Barclays and BofA Securities are named as bookrunners. Additional underwriters include Evercore ISI, Guggenheim Securities, Wolfe | Nomura Alliance, and BNP PARIBAS.
The filing does not specify how many shares the company plans to offer, nor does it include an expected price range for the IPO.
Operational and market context
ERock positions itself as an integrated provider across the life cycle of its distributed power systems, from design and deployment through ongoing operations and maintenance, emphasising proprietary hardware and embedded software. The company highlights long-tenure operational experience and a sizable installed base, underscoring its established presence in the markets it serves.
Transaction status
The firm has engaged a syndicate led by Morgan Stanley and J.P. Morgan, with Barclays and BofA Securities as bookrunners and several other firms included among the underwriters. The filing leaves open key transaction variables: number of shares and price guidance remain undisclosed at this stage.
What remains unspecified
While the filing provides detail on ERock's technology, customer segments, footprint, installed capacity and backlog, it does not reveal the proposed offering size, share count or pricing range, leaving the timing and financial scale of the market debut unclear.
