performance degradation, or costly downtime. As a result, these facilities increasingly require the ability to maintain continuous operation during short-duration grid disturbances, supported by fast, on-site frequency control and power stabilization capabilities. Strong transient response enables stable voltage and frequency during these sudden changes and supports seamless transitions between grid power, on-site generation and battery storage systems, helping to prevent equipment malfunctions, data corruption and costly downtime. Our natural gas generators also offer meaningful reliability advantages over diesel-based solutions, which depend on continuous fuel deliveries that can be disrupted by severe weather, transportation constraints or supply-chain interruptions. By contrast, our power systems operate on natural gas delivered through a resilient underground natural gas infrastructure, which reduces the operational risks associated with refueling. We believe that the combination of diesel-equivalent transient performance and a reliable fuel supply positions our power systems to meet the demanding requirements of mission-critical data center operations.

maintenance scheduling and system optimization. Whether deployed for bridge, dispatchable or backup power applications, our ERock Platform’s comprehensive capabilities uniquely position us
to deliver accelerated time-to-power and firm resiliency solutions.

Highly Differentiated, Proprietary Power System
Serving Multiple Use Cases. Our highly differentiated, proprietary natural gas power systems are engineered to serve multiple mission-critical use cases through a single integrated power system. Leveraging our quick-response, patented generator
technology and modular, emissions-advantaged design, our power systems provide cost-effective, resilient and turnkey solutions for bridge, dispatchable and backup power applications. As bridge power, our power systems enable the rapid deployment of
reliable capacity that arrives with customer load demand and mitigates delays associated with long-lead grid capacity upgrades. As dispatchable capacity, our power systems function as on-demand, fast-response resources that support grid stability
and help large energy users balance load demand and participate in market-driven dispatch strategies. As backup power, our power systems deliver highly reliable continuity for mission-critical operations during grid disruptions or extreme weather
events such as extreme temperatures, earthquakes, hurricanes, typhoons, derechos, wildfires and flash floods. Our power systems come integrated with our purpose-built Granite platform, which enables real-time monitoring, predictive diagnostics and
dynamic asset optimization. With advanced data analytics, sub-second data collection and fleet-wide benchmarking, Granite supports preventive maintenance, remote dispatch and market participation, supporting
operational efficiency and maximizing asset value. Our power systems multi-use capability, combined with best-in-class emissions, a compact footprint and a standardized, scalable packaging architecture, represents a unique customer value
proposition, offering superior performance, rapid deployment and compliance with the most stringent standards.

Engineered for Rapid Deployment and Scale. Our patented natural gas generator technology is engineered for rapid
installation, serviceability and ultra-low local emissions in compliance with CARB-DG. Our CARB ultra-clean emissions package reduces key pollutants (NMHC, NOx, CO) by
approximately 95%+ relative to diesel. The compact footprint and modular design of our pre-integrated RockBlock systems enable rapid deployment and easy siting, while oversized cooling systems and extensive
telemetry support optimal performance and compliance with the most stringent operating standards, which supports an accelerated permitting process and community acceptance. Our ability to construct modular strings of back-to-back generators, each
with a smaller individual footprint than comparable natural gas reciprocating generators, allows us to achieve systems with approximately half the footprint of comparable natural gas reciprocating generator systems. The standardization of our
RockBlock fleet further allows us to deliver reliable, cost-effective power solutions at scale as it simplifies maintenance by enabling uniform service procedures, interchangeable parts and consolidated training programs, which lowers downtime and
improves reliability, allows us to optimize performance monitoring and implement uniform operational protocols, resulting in higher utilization and reduced variability in output, and provides economies of scale in procurement and inventory
management, while accelerating deployment timelines for new projects by reducing variability and complexity. We believe our power systems are well positioned to enable our customers to deploy reliable, dispatchable utility-grade power at scale
faster than our competitors.

Significant Track Record and Feedback Loop Supporting Continuous Improvement.
Our experience across approximately 400 sites representing approximately 1,000 MW of commissioned capacity over 15 years of operations provides us with a uniquely robust data foundation supporting continuous improvement of our technology and
processes. This scale of real-world operating experience—built over 1.9+ million runtime hours across our entire fleet and reflected in our long-standing field services and engineering capabilities—enables us to optimize power system
performance and enhance our core services for all of our customers. As a vertically integrated provider, we capture operational learnings across the entire lifecycle of all of our power systems, allowing us to systematically feed customer, field and
operational performance data back into our design, engineering, assembly, commissioning, O&M and asset management processes. This closed-loop feedback mechanism supports measurable gains in enhancing our product offerings, services and assembly
performance

and enables us to leverage the insights gained from across our entire fleet to deliver more to our customers and stakeholders.

Embedded Relationships with Utilities, ISOs and Policy Makers. We have built deep, long-standing relationships with
leading utilities, ISOs and policymakers across the United States—partnerships founded on trust, proven performance and a track record of delivering value in mission-critical applications. In several cases, these relationships have resulted in
proprietary offtake and commercial arrangements with utilities such as Entergy and CPS Energy, as well as other potential arrangements that are under development. These arrangements involve bespoke, utility-specific carve-outs and structures that
are not available on a generalized tariff basis and are not broadly accessible to other market participants, reflecting a high degree of confidence in our capabilities and operating model. These relationships enable us to execute effectively because
the utilities, ISOs and policy makers know us, rely on our expertise and work closely with us to address their most pressing challenges. We also actively help create new markets for utilities by opening opportunities in both regulated and
deregulated jurisdictions while securing attractive economics for our customers. Our positioning also facilitates faster interconnections and tailored solutions for our customers, whether the objective is to increase available capacity, support grid
resilience initiatives or improve outcomes within existing utility and ISO frameworks. By serving as a trusted intermediary between companies and utilities and ISOs, we align interests, help solve complex problems and unlock new business
opportunities, including from utility-sponsored projects and direct referrals from utilities that view us as a reliable partner with demonstrated ability to deliver differentiated solutions.

Asset-Light Business Model Supports Balance Sheet. Our asset-light business model enables us to scale efficiently while
supporting a strong and flexible balance sheet. Because we do not lease or own the power systems we deploy—and instead sell those systems to customers, including third-party investors—the assets do not reside on our balance sheet and are
typically financed through customer or investor payments, allowing us to recycle capital rapidly and avoid the capital-intensive burden typical of traditional infrastructure models. As a result, we require significantly lower capital expenditure
than our peers and do not expect to require external capital to support our growth for the foreseeable future. In addition, because we provide comprehensive O&M and asset-management services through the ERock Platform, each power system we
deploy has the potential to become an additional source of ongoing services revenue with limited incremental cost or capital. This business model avoids idle-asset risk, creates meaningful operating leverage as every additional MW we install can
expand our service base and enables us to grow while preserving both capital efficiency and balance-sheet strength.
