ERock EROC

ERock, Inc. is a vertically integrated company that designs, deploys, operates and maintains multi-purpose distributed power systems, consisting of its proprietary, low emission, quick-response natural gas generator and embedded software technology. The company serves data centers, utilities and large commercial and industrial customers across the United States, with its largest operating footprints located in California and Texas. ERock, Inc. delivers resilient, cost-effective, modular power systems that can be rapidly deployed at a scale of more than 1 GW to meet customers’ full range of power needs, including bridge, backup and dispatchable power applications, and are supported by its operations and maintenance and asset management services.

ERock, Inc. generates revenue through a combination of power system sales and services, which allows it to realize revenue from equipment sales, site buildout, installation and commissioning, and recurring revenue from operations and maintenance and asset management services post-commissioning. While the company does sell its generators as a standalone product, most sales include the comprehensive design, delivery, installation and long-term services provided by the ERock Platform, with platform sales representing 100% and 98% of all generator sales booked in 2024 and 2025, respectively. Power system sales revenues are generated from selling natural gas power systems to customers inclusive of engineering, procurement and construction services, and the company reports these revenues as product revenues and installation services revenues.

ERock, Inc. operates through the following segments:

• ERock Platform: This segment provides a comprehensive, turnkey solution for the design, delivery and installation of distributed power and resiliency projects. The ERock Platform combines proprietary natural gas engine and generator technology with engineering, procurement and construction services, operations and maintenance, advanced asset management, white label programs and flexible financing and contract support. The platform enables customers to deploy reliable, dispatchable and cost-effective power solutions with a single partner across the entire life cycle of the power system.

The ERock Platform includes proprietary technologies such as the RockBlock, a modular, distributed generator string that incorporates the company’s natural gas engine and scales in 0.5 MW increments from 1.5 MW to 3.5 MW per unit, and Granite, a proprietary software that is embedded in the power systems and enables real-time data collection, predictive diagnostics and dynamic asset optimization. These technologies support operational efficiency, reduce operating costs and enhance the value customers can capture from their power assets. The segment also encompasses engineering, procurement and construction services, operations and maintenance services, asset management services and white label program services, allowing ERock, Inc. to act as an end-to-end partner for resilient, scalable and clean power solutions.

ERock, Inc. is positioned as a leading provider of distributed power generation solutions in the United States, with a competitive advantage derived from its vertically integrated ERock Platform, proprietary generator technology and software-enabled services. The company competes favorably against traditional diesel generators, gas turbines, fuel cells and battery storage systems due to its superior fast response, diesel-equivalent transient performance, 99.999% reliability and ability to operate without on-site water. ERock, Inc.’s power systems are engineered for superior operational stability, including quiet operation, low emissions and rapid deployment, which differentiates it from competitors with more capital-intensive or less flexible models. The company’s ability to deliver power in less than six months and achieve full project commissioning within 12 to 18 months from contract signing provides a significant speed-to-market advantage in markets with long interconnection queues.

ERock, Inc. serves data centers, utilities and large commercial and industrial customers across the United States. The company has established relationships with major technology and industrial firms such as Microsoft, Wistron, Foxconn, H-E-B and Walmart, as well as electric and gas utilities including Entergy and ComEd.
