ERock ^{Filed, US Offering, NYSE: EROC}

We are a vertically integrated company that designs, deploys, operates and maintains multi-purpose distributed power systems, consisting of our proprietary, low emission, quick-response natural gas generator and embedded software technology, for our customers. Our resilient, cost-effective, modular power systems can be rapidly deployed at a scale of more than 1 GW to meet our customers’ full range of power needs, including bridge, backup and dispatchable power applications, and are supported by our operations and maintenance (“O&M”) and asset management services. We deploy our systems in three applications: bridge (prime-to-backup), backup (resiliency) and dispatchable (flexible capacity) power. Our services: Bridge power (prime-to-backup) deliver prime power in the near-term to accelerate time-to-power ahead of long-lead grid upgrades, Backup power (resiliency) provide highly reliable continuity for mission-critical operations during grid disruptions and extreme weather events, Dispatchable power (flexible capacity) are configured as on-demand, fast-response resources and can be deployed by contract to market-facing objectives. We primarily serve data centers, utilities and large C&I businesses across nine U.S. states, with our largest operating footprints located in California and Texas, where we anticipate growth and market potential driven by high data center demand.
