Erock, Inc.
A Houston-based energy company that designs, builds and runs modular, onsite natural-gas power systems, selling "electrical resiliency-as-a-service" to businesses that must keep running through grid outages, storms or cyberattacks. It began in 2006 as Enchanted Rock, named after a legendary pink granite dome in the Texas Hill Country that Native American tribes considered sacred, and officially shortened its name to ERock in 2026 ahead of its stock-market debut. Its founders were a nuclear engineer and a former NASA aerospace engineer who drew on ship and spacecraft reliability know-how.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
