to improve operations for high reliability at a lower cost. Granite architecture is a combination of real-time device data collection as well as distributed and aggregated data process and analytics. At the device level, Granite captures real-time data from our power systems’ ECU, controllers and balance of plant at sub-second intervals—far faster than typical SCADA systems—and uses advanced analytics to enable predictive diagnostics, dynamic site-level optimization and adaptive maintenance scheduling. Granite also allows remote 24/7 monitoring and centralized control from our NOCs, supporting thousands of assets and enabling market interactive peak shaving and grid services at distributed or aggregate levels. In addition, by comparing performance across power system units, sites and fleets, Granite identifies operational patterns and anomalies, supporting maximum uptime and efficiency across all systems while at the same time reducing operating costs. Generators procured outside of our ERock Platform do not come with Granite embedded in their systems.

To maintain our competitive edge, we are advancing a robust research and development (“R&D”) pipeline designed
to enhance core generator and software technology offering and expand into new energy solutions that meet evolving customer needs. Our roadmap builds on the success of our RockBlock systems, with the goal of delivering greater reliability,
simplified installation and improved operational flexibility, integration with other onsite energy technologies, such as battery energy storage systems, as well as additional, complementary products. A key focus is the continued evolution of
Granite, with the goal of delivering higher reliability through predictive diagnostics, preventive maintenance and dynamic integration of distributed assets into a unified system. These innovations are intended to allow customers to optimize
performance, reduce operating costs, and accelerate deployment timelines, while positioning ERock as a leader in scalable, intelligent power solutions for the future.

Our Services

We offer a
fully integrated suite of services through our ERock Platform that supports rapid deployment, reliable operation and maximizing value from distributed power assets. Our offering spans comprehensive design, ESI project delivery, O&M, advanced
asset management, white label programs and flexible financing and contract support—making us an end-to-end partner for resilient, scalable and cost-effective power
solutions.

ESI Services. We provide a turnkey solution for the design, delivery and installation of distributed
power and resiliency projects. Our ESI offering is comprehensive and tailored, encompassing:

• Site Assessment & Feasibility : Our team helps customers conduct detailed site evaluations,
including load analysis, utility interconnection studies and environmental assessments, to assess optimal system design and project viability.

• Natural Gas Interconnection and Site Availability : We conduct natural gas availability and
interconnection studies for our customers.

• Permitting and Regulatory Compliance : We manage air and construction permitting and regulatory
approvals, leveraging deep experience with local, state and federal requirements to streamline the process and minimize project risk.

• Custom System Design : Our engineers develop tailored solutions that integrate our proprietary generator
technology with other distributed energy resources such as solar, battery storage and turbines, integrated with switchgear, transformers and other equipment to deliver a comprehensive power system. Each system is designed for maximum reliability,
efficiency and scalability.

• Procurement and Supply Chain Management : We oversee the sourcing and procurement of major equipment and
materials, utilizing a robust and diversified supply chain to support timely delivery and cost control.

• Construction and Installation : Our experienced construction teams manage site preparation, equipment
installation, electrical and gas interconnections and commissioning. We emphasize safety, quality and speed, with modular, kitted solutions that enable rapid deployment and minimize onsite disruption. We have a proven track record in safety with
average TRIR of 0.93 for the years ended December 31, 2025, 2024 and 2023. We conduct weekly company-wide safety meetings and biweekly safety trainings in addition to other ad hoc safety trainings. We also have a designated safety leader
responsible for advancing our culture of safety.

O&M Services. Our O&M services are
designed to ensure maximum reliability, uptime and performance for every installed power system. Our O&M offering is comprehensive, technology-enabled and performed by our employees, encompassing:

• 24/7 Remote Monitoring : Assets monitored from our NOCs, utilizing the Granite software platform. This
allows for real-time visibility into system health, performance and operational status across our fleet of distributed assets.

• Preventive Maintenance and Rapid Response : Our O&M team conducts regular preventive maintenance,
leveraging predictive diagnostics and data analytics to identify and address potential issues before they impact operations. In the event of an alert or outage, our team is equipped to dispatch field technicians rapidly, minimizing downtime and
restoring service quickly.

• Comprehensive Service Coverage : O&M services include scheduled maintenance, unscheduled repairs,
warranty management, inventory and spare parts management and compliance with regulatory requirements. Our technicians are trained to service the entire generator system, including engine, alternator, cooling, lubrication and control systems, and
benefit from working on a standardized RockBlock system used across our fleet, giving them extensive experience with the same equipment, which we believe leads to increased productivity, lower costs and improved quality and consistency.

• Performance Optimization : Through advanced data analytics and benchmarking, we compare performance
across units, sites and fleets to identify outliers and optimize asset operation. Granite enables dynamic adjustment of maintenance schedules based on real-time operating conditions and historical data, reducing unplanned outages and lowering total
cost of ownership.

• Customer Support and Reporting : Customers receive regular performance reports, maintenance updates and
direct access to our support team for operational questions or needs.

Asset Management. We
provide comprehensive monetization services, acting as advisor or agent for owners of our deployed power systems of 724 MW, to optimize grid revenues through electricity and natural gas market participation, hedging and dispatch strategies. We
partner with customers early in the site assessment and feasibility phase to evaluate potential market programs and revenue opportunities, integrating monetization considerations directly into the initial contracting and business-development
process. Our approach focuses on evaluating the possible market programs or revenue streams best suited for our power systems, helping customers select monetization strategies designed to maximize the value of their assets by seeking to obtain the
highest risk-adjusted returns. We also support hedging and risk management for customers and develop programs tailored for specific power markets.

White Label Program Services. We partner with utilities, such as Entergy, to design and execute white label resiliency
programs, enabling them to offer branded reliability solutions. These programs allow our partners to deliver differentiated, customer-facing reliability offerings under their own brand while leveraging our expertise and infrastructure.

Financing and Contract Support Services. To facilitate project development, we offer robust financing and contract
support, coordinating and arranging project financing and providing guidance on contract structuring and risk management. Our flexible asset ownership and value-sharing models—including Resiliency-as-a-Service and third-party financing vehicles—enable customers to deploy solutions with minimal upfront capital and predictable long-term costs.
