to deliver dispatchable power because current battery technology cannot reliably satisfy the amount, duration or quality of electrical power required by large, often continuous or highly sensitive loads. In certain configurations, ERock systems can facilitate earlier access to grid interconnection compared to traditional standalone processes. In addition, our systems may serve as grid-support assets during peak demand or scarcity events, which can enhance project economics and contribute to local grid reliability. However, interconnection outcomes vary by jurisdiction and remain subject to utility and regulatory approval. Regulatory frameworks are evolving to support co-located generation and large loads. On December 18, 2025, FERC directed PJM Interconnection to establish transparent rules to facilitate service for large loads co-located with generation, including creating new transmission service options and clarifying interconnection procedures to address reliability and consumer-cost concerns associated with rapidly growing load. Similar programs are being deployed in ERCOT and pursued in other markets.

Our approach to rapid deployment involves selecting the optimal combination of our onsite generating technologies, including
our proprietary natural gas generators, to deliver reliable power to maximize our customers’ utilization of grid infrastructure. Our ERock Platform delivers modular power systems that are designed and kitted for streamlined field assembly and
deployment to maximize time efficiency and minimize trade labor during construction, which supports rapid installation and commissioning so customers can get up and running faster. Our ERock Platform also allows us to leverage commoditized component
supply chains that do not require specialized equipment for generator final assembly, accelerating deployment timelines and enabling capacity additions of approximately 1.2 GW in less than 12 months. Our proprietary generator technology has best-in-class local emissions, quiet operation and fits inside the footprint of a like size diesel unit, allowing customers to permit more easily, have greater headroom to
scale bridge power before requiring time-consuming, major source air permits, avoid additional real estate requirements and reduce or eliminate the need for and associated costs of sound mitigation, thereby improving speed of construction and
community acceptance. In 2022, our generators became the first of their kind to secure CARB-DG certification, which has some of the strictest emission requirements in the world. No other reciprocating engines
have received CARB-DG certification. Moreover, water use is in many jurisdictions receiving increasing scrutiny from utilities, regulators and local communities due to growing concerns around water scarcity,
drought resilience, infrastructure strain and environmental sustainability. Our power systems are designed to operate with no on-site water required, eliminating the need for withdrawal, consumption or discharge of water as part of normal
operations, further supporting community acceptance of our power systems.

Highly Economic Path to Bridge and
Dispatchable Power Solutions

Our power solutions provide customers with a highly cost-effective path to reliable,
utility-grade bridge and dispatchable power because our systems are engineered for both bridge and fast response dispatchable power applications. In contrast to stranded temporary infrastructure, once our customers are fully interconnected with the
grid, our power systems can continue to serve customers as a reliable, dispatchable utility-grade power source with fast response, diesel-equivalent transient performance to supplement the grid and provide industry leading reliability for protection
against grid outage events. This long-term, multi-purpose design of our power systems helps customers, particularly customers with large electricity loads such as data centers, to reduce the total cost of ownership by providing multiple value
streams through the full useful life of the asset. By transforming bridge power installations into assets that continue to return value to the customer, our power systems support a more enduring and economically efficient bridge power development
model compared to conventional temporary generation.

Highly Cost-Effective and
Low-Risk Path to Increase Grid Capacity

As utility capital expenditures
surge and electricity rates continue to rise due to increased demand for electricity, our power solutions provide a highly cost-effective and low-risk path to increasing grid capacity.

Traditional grid-expansion planning often relies on long-term demand forecasts, requiring utilities to make large, long-dated capital commitments, and utilities are increasingly asking large new
electricity loads—such as data centers—to share in those costs despite having significantly shorter planning horizons. This mismatch introduces substantial risk of stranded investment, overbuilding and misaligned capacity
expansion—issues that regulators have become increasingly focused on as grid-upgrade proposals grow in scale. By contrast, our co-located distributed power systems arrive with the load itself, are
typically paid for by the customer deploying the load and provide capacity concurrent with when the load comes online, eliminating the need for utilities to build ahead of requested demand. By enabling large new electricity loads to self-fund and
install our distributed power systems, our platform increases capacity without requiring utilities to undertake costly grid upgrades in advance of demand and, once interconnection occurs, our power systems remain in place as a stable source of power
supply for the grid that reduces or defers the need for further capital investment by utilities on grid expansion and helps moderate system-wide electricity rate impacts for existing customers. As a result, our power systems can help accelerate the
interconnection timeline as utilities benefit from our bridge power solutions by securing new electricity load and associated revenues earlier, and customers benefit from dependable, distributed power while avoiding lengthy delays associated with
traditional grid expansion. We have successfully deployed this approach for years, repeatedly demonstrating that customer-funded, distributed power systems can compress timelines by delivering immediately available capacity that can relieve
near-term grid constraints. This proven model is now being embraced by leading markets such as PJM and ERCOT, where regulators, utilities and ISOs are increasingly adopting similar approaches to facilitate faster, lower-risk interconnections. This
dynamic creates a mutually reinforcing outcome—reduced capacity planning and capital-deployment risk for utilities and a faster, more predictable path to power for customers.

Highly Reliable Path to Resilient, Firm Power

We believe our ERock Platform’s proprietary generator and operating software technology delivers a 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, 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 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 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.
