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. Table of Contents Our Primary End Markets Data Centers (Speed-to-Power). We partner with hyperscale and “colocation” data centers, providing rapid deployment of scalable, utility-grade backup and bridge power solutions. Our technology enables data centers to accelerate site commissioning, meet stringent reliability, sound and emissions requirements while supporting AI-driven load growth. We can provide power generation solutions for data center customers that enables fast-track data center construction and operation with prime power, ability to accelerate access to grid interconnection, prescribed flexibility and revenue generating grid services, and supports 24/7 reliable operations—all from a single generator technology platform, our ERock Platform, across the lifecycle of a data center buildout and operation.

Utilities (Grid Stability and Cost-Effective Capacity Expansion). Utilities leverage our distributed power generation
assets to address rate pressure, grid stability, reliability and emergency backup, and capacity constraints and demand response. Our power systems offer dispatchable, cost-effective capacity that helps utilities avoid costly infrastructure upgrades
and respond to regulatory demands for cleaner, more resilient power and supports overall grid stability during peak demand or scarcity events. We also have proven partnerships with major utilities in storm-prone and high-growth regions. We offer our
solutions through turnkey system sales, in which we design, deploy and operate our power systems as fully integrated, customer-ready offerings, under white-label arrangements that allow our customers (e.g., a utility) to present these systems as
part of their own branded energy solutions. We also enter into capacity offtake agreements that are structured to reflect the high availability and performance of our aggregated portfolio of distributed generation assets. In addition, our
longstanding relationships with utilities help large loads navigate the interconnection process and meet the technical and contractual requirements necessary to secure flexible conditional firm interconnections, creating a meaningful speed-to-power
pathway for rapid deployment and earlier access to reliable capacity.

customers—including retailers, manufacturers, healthcare providers, logistics companies and government entities—rely on us for resilient backup power and operational continuity as well as cost savings from grid services like peak demand
reduction. Our power system solutions help protect critical infrastructure and enterprise operations from power outages and other grid disturbances, reduce emissions and support sustainability goals compared to traditional resilience solutions, such
as diesel.

Our Competitive Strengths

We believe the following characteristics differentiate us from our peers and uniquely position us to execute on our strategy to
create value for our stakeholders:

Reliable, Fast-Response Generator Technology. Our patented natural gas
generator technology achieves diesel-equivalent transient performance response requirements, which is a critical capability for data centers that experience highly dynamic electrical loads. These facilities routinely see rapid fluctuations in power
demand within milliseconds due to workload spikes, server startups and cooling system adjustments. Modern data centers, particularly large, high-density facilities supporting AI training, cloud computing and other high-performance workloads, and
next-generation semiconductor chips such as AI accelerators, GPUs and custom silicon are placing growing demands on electrical power systems. These environments draw enormous and highly variable amounts of electricity and are far more sensitive to
power quality than prior generations of computing infrastructure. Even very brief frequency deviations, voltage dips, or other grid disturbances can cause system instability, 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.

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.
