ERock Inc. experienced a disappointing first day of trading on the New York Stock Exchange Wednesday, with shares closing at $18.84, a 12.37% decline from its initial public offering price of $21.50. The stock opened at $20.10 under the symbol EROC.
The Houston-based on-site power generation company raised approximately $600 million in its IPO, offering 27,906,977 Class A shares at $21.50 each, the midpoint of its expected range. Underwriters have a 30-day option to purchase up to 4,186,046 additional shares. The deal is expected to close on June 11, pending customary conditions.
ERock's market debut came as investors weighed the company's compelling growth narrative against significant execution risks. The company specializes in modular natural gas power systems designed to deliver electricity quickly to customers before they can connect to the full grid, targeting data centers, utilities, and other large energy users facing grid constraints.
The company's $1.28 billion contracted power-system sales backlog as of March 31, a staggering 778.6% increase year-over-year, is a central focus for investors. Nearly all of the backlog growth in the first quarter and throughout 2025 has come from data-center customers. CEO John Carrington indicated that approximately $1.1 billion of this backlog is tied to AI data-center projects, with most new contracts scheduled for delivery within 12 to 18 months.
A key contract fueling interest is with Meta Platforms, where ERock is working with El Paso Electric to deliver 366 megawatts of on-site generation for Meta's planned $10 billion AI data center in El Paso, Texas. This deal underscores the massive power demands of AI infrastructure.
However, investor skepticism centers on whether this backlog will convert into actual revenue. ERock disclosed in its SEC filing that customers can cancel, change, or delay deals in some cases, warning it might not book all the backlog as revenue. The company also faces pressure from rapid growth, needing to scale up assembly and service operations without disappointing customer expectations.
These concerns are compounded by the company's financial performance. For the quarter ending March 31, ERock reported revenue of $31.7 million, up 31.6% from the prior year, but recorded a net loss of $17.2 million. For full-year 2025, revenue was $183.1 million with a net loss of $59.0 million.
IPOX Research Associate Lukas Muehlbauer commented that investors are pushing back on the valuation amid execution risk, highlighting the market's cautious stance. The company's valuation stood at $5.49 billion fully diluted at the opening price.
