Houston‑based Erock Inc., a maker of modular power systems for data centers, filed a U.S. IPO on Friday. The S‑1 shows revenue of $31.7 million for the quarter ended March 31, 2026, up from $24.1 million a year earlier, while net loss widened to $18 million from $16.7 million. Shares will list on the NYSE under EROC. The prospectus notes a cash balance of $12 million in 2026.

Erock’s flagship product, RockBlock, combines a proprietary natural‑gas engine with a distributed generator string, targeting roughly 400 customer sites. California and Texas host the bulk of installations, reflecting regional data‑center growth. Sponsor Energy Impact Partners backs the company, positioning it to capture utility‑scale demand for clean, on‑site power amid rising energy costs. The technology aligns with regulators’ push for lower emissions in high‑density computing hubs.

Investment banks Morgan Stanley and JPMorgan Chase are leading the deal, signaling confidence in a niche yet expanding market. With losses still sizable, investors will weigh Erock’s growth trajectory against capital‑intensive scaling. The IPO proceeds could significantly fund additional manufacturing capacity and R&D, sharpening the firm’s edge in distributed power solutions.
