highly reliable path to resilient, firm power. Our power systems are designed for continuous, fault-tolerant operation—meaning they can maintain power output even when components fail or experience abnormal conditions—delivering reliable power when the grid is not available and provide backup power with lower emissions and noise than diesel alternatives. Our backup power solutions offer high operational reliability with inherent redundancy for fault tolerance and concurrent maintainability—meaning critical components can be serviced, repaired or replaced without shutting down the system—to facilitate deployment in mission-critical backup applications. Fueled by natural gas delivered through underground pipelines with no runtime limitations, our power systems have proven capable of delivering uninterrupted power through hurricanes, winter storms and everyday grid outages. As grid outages have become longer and more frequent, and where fuel deliveries can be delayed during severe weather, we deliver proven backup power solutions that keep critical facilities online during grid outages and emergencies.

Our Generator and Software Technology

We provide reliable, resilient and cost-effective power primarily through a proprietary, tailored, integrated power systems
delivered through our ERock Platform, a comprehensive offering consisting of our generator and software-enabled O&M and asset management services described below.

At the core of our power systems is our RockBlock (“RockBlock”), a modular, distributed generator string that
incorporates our proprietary natural gas engine, scales in 0.5 MW increments from 1.5 MW to 3.5 MW per RockBlock and is assembled in-house. Our RockBlock systems convert natural gas from local underground
pipelines into electricity through a combustion process and are capable of continuously operating at their designed capacity with 99.999% reliability. Our RockBlock systems are engineered for maximum cost efficiency through their modular design and
standardized kit, which supports rapid delivery, field construction and scaling. Our power system units feature a patented design that occupies approximately half the footprint of comparable natural gas units, while maintaining low sound levels
across varying applications and achieving diesel equivalent transient performance, while meeting stringent local emissions standards, including CARB-DG compliance, one of the most rigorous emissions standards in the United States.

Complementing our generator technology is our Granite Software Ecosystem (“Granite”), a proprietary software that
is embedded in our power systems and enables us to use operating data 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 network operations centers
(“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.

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.

O&M Services. Our O&M services are designed to ensure maximum reliability, uptime and
performance for every installed power system.

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.

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.

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.

Policy Advocacy and External Affairs. Our team of policy experts actively monitors and shapes policy at the local,
state and federal level to support current and prospective customers’ use of natural gas onsite generation in their overall energy strategy.

Our
Business Model

We generate revenue through a combination of power system sales and services, which allows us to
realize revenue from equipment sales, site buildout, installations and commissioning and recurring revenue from O&M and asset management services post-commissioning.

Power System Sales Revenues. We generate revenue from selling our natural gas power systems to customers inclusive of
the design and ESI of turnkey power system solutions, and we report these revenues as product revenues and installation services revenues. Power system sales product revenues consist of product sales of generators and related equipment to produce
our power systems. Power system sales installation services revenues consist of ESI services to design, construct, install and commission our power systems. Customers enter into ESI contracts to purchase our power systems, and these contracts also
typically cover design and ESI services of such power systems. Our ESI agreements are generally structured such that customers pay a percentage of the contract price at execution, additional percentages upon the achievement of specified milestones,
such as equipment delivery and installation, and the remaining balance upon successful completion of testing and commissioning.

Ongoing Services Revenues. After installation and commissioning, we enter into long-term service agreements for O&M
and asset management services. Our typical services contracts range from 5 to 15 years and include both preventative and corrective services. These contracts typically include remote monitoring, preventive maintenance, rapid response and warranty
support. Asset management contracts may also cover dispatch optimization, market participation and regulatory compliance. Recurring service fees are billed monthly for the duration of the contract and include a fixed service fee and, in some cases,
a fee based on the financial performance of the power systems, with additional amounts payable on a per-work-order basis. The weighted average term of our O&M and asset management services agreements is
approximately 10 years. To date, none of our customers have terminated or failed to renew our O&M or asset-management services.

Our Customers and
Markets

We serve customers across the United States, with a proven track record in data centers, utilities and C&I
sectors. Our geographic footprint spans eight states and four major RTOs, with approximately 1,000 MW in deployed operating assets with an estimated current replacement value of approximately $1.4 billion. Our proprietary generator and software
technology platform is trusted by leading enterprises and utilities to deliver reliable, dispatchable, and cost-effective power across a rapidly expanding footprint.

Our Key Highlights of Deployed Assets and Contracted Power System Sales Backlog

Our first distributed power system was commissioned in 2011 and since then our operations have grown to approximately 400
operational sites, with approximately 1,000 MW deployed operating power systems, approximately $1.4 billion in deployed operating assets and approximately $1.2 billion in Contracted Power System Sales Backlog as of December 31, 2025
representing approximately 3x faster growth than the market from 2024 to 2025.
