systems are configured as on-demand, fast-response resources and can be deployed by contract to market-facing objectives (such as peak-load management or grid-stability services). We primarily serve data centers, utilities and large C&I businesses across eight U.S. states, with our largest operating footprints located in California and Texas, where we anticipate disproportionate growth and market potential driven by high data center demand in the near- and medium-term. With over 15 years of operational experience, over 2,000 deployed units across approximately 400 operational sites consisting of an installed base of approximately 1,000 MW and Contracted Power System Sales Backlog of approximately $1.2 billion as of December 31, 2025, we believe we are one of the most established, proven providers of bridge, backup and dispatchable power applications for the growing distributed power generation market. Table of Contents Target states represent those currently in our pipeline or designated as target geographies by our management.

Over the last 15 years, we have established deep expertise and a proven track record in
the deployment of complex integrated power systems through our ERock Platform. We refer to the delivery and operation of our generators and integrated software technology through our comprehensive, turnkey equipment, supply and installation
(“ESI”), O&M and asset management services platform, supported by our deep development, operational and market domain expertise in integrated power systems, as our “ERock Platform.”

Most of our sales include the comprehensive design, delivery,
installation and long-term services provided by the ERock Platform, with platform sales representing 100% and 98% of all generator sales booked in 2024 and 2025 respectively. Leveraging our ERock Platform, we help customers meet evolving energy
demands by delivering cost-effective, turnkey speed-to-power and resiliency solutions that supplement and maximize traditional grid infrastructure. Our power systems are engineered for superior operational
stability, including:

• Reliability . Our systems are capable of 99.999% reliability.

• Diesel-equivalent transient performance . Our generators meet or exceed rigorous ISO 8528-5 G3 diesel standards, delivering fast, stable responses to sudden load swings, and we believe we are currently the only provider of natural gas generation that meets utility-grade transient performance
requirements for diesel units, which reduces the need for additional technology to deliver required power quality.

• Quieter, cleaner and rapidly deployed . Our power systems are typically quieter, cleaner, more resilient
and dispatchable, and can be deployed and commissioned more rapidly than traditional grid infrastructure and other conventional alternatives.

• No on-site water required . As water use by data centers is receiving increasing scrutiny, our power
systems are designed to operate with no on-site water required.

Our experienced O&M teams
handle all aspects of preventive and corrective maintenance, and our purpose-built software that is embedded in our power systems provides extensive operational data capture and analytical capabilities, enabling greater resilience of generator
technology and dynamic, insight-driven maintenance schedules. These performance attributes and our expertise in developing, deploying and maintaining integrated power systems differentiate us from our competitors and support our strong customer
relationships, which is evidenced by our proven track record of delivering reliable, integrated power solutions.

Once connected to the grid, we also assist customers to maximize the return
on their investment in our power systems by leveraging its multi-purpose dispatchable power capabilities through our market operations and dispatch management platform, acting as advisor or agent for owners of our deployed power systems of
724 MW. These services allow customers to utilize our power systems for backup power as and when needed or to strategically dispatch capacity from our power systems during peak demand or scarcity events—ultimately enabling our power
systems to become a grid asset. Our asset optimization capabilities and market expertise enable us to monetize our power systems capacity, reduce costs to customers in almost any market and reduce times to grid interconnection. Our distributed power
systems have consistently operated in support of the grid.

Over the past eight years, we have supported over 236,000 Grid
Support Events. Each event represents a documented start and stop of our distributed generation systems undertaken to provide power to the grid during periods of actual or anticipated grid constraints, either in response to a direct request from the
grid operator or pursuant to incentive based programs, such as scarcity pricing or peak demand load shed programs, that compensate generators for providing such support. Under our O&M and asset management services agreements, customers authorize
us to dispatch and operate the power systems during Grid Support Events when their operations do not require dedicated output from our power systems. When the grid is down, our power systems can displace grid supply (i.e., island the
customer’s load from the grid) and provide utility-grade power directly to the customer; when the grid is operating normally, our power systems remain interconnected and operate in parallel with the grid, enabling us to deliver grid-supporting
services. During Grid Support Events, when customer operations allow, we can provide the available capacity of our power systems through both offsetting the customer’s load consumption and exporting any additional available capacity to the
grid in exchange for program based compensation or other incentives that benefit our customers. We believe this operational experience is increasingly valuable as grid operators seek alternative tools to address resource adequacy and congestion
management for large loads. Power outage responses and power quality operations are separate from, and in addition to, these Grid Support Events.

We assemble our proprietary engines and generators at our Titan facility and are targeting increasing our annual assembly
capacity to approximately 1.2 GW by the end of 2026 with the development of our Hyperion facility, both located in Houston, Texas. Our assembly model is designed to scale efficiently and rapidly to meet growing customer demand and service our
backlog, leveraging a high-volume, largely multi-sourced supply chain and standardized assembly processes. This approach allows us to expand output without the need for extensive new capital investment or specialized equipment, enabling low-cost, high-velocity capacity expansion while maintaining assembly flexibility and supply-chain security. As we increase capacity to meet accelerating demand, we are able to produce and deploy additional power
systems while maintaining strong control over our supply chain, costs, efficiency and product quality, which supports higher margins. In addition, growing our generator deployment also accelerates our innovation cycle as the real-world operating
data of our power systems in the field informs improvements to our design, development and installation processes. We believe this feedback loop, enabled by our vertically integrated business model and scalable assembly capabilities, helps drive a
faster innovation cycle, supports reliable execution at scale and differentiates us from our competitors with more capital-intensive or less flexible assembly models. For example, insights from field installations have allowed us to pre-configure
and kit key generator components in our production process, reducing installation costs by 20% and creating a continuous improvement cycle between engineering, production and field operations.

Over the past decade, we have built a foundation of deep trust and relationships with leading data center and AI ecosystem
companies, such as Microsoft, Wistron and Foxconn, electric and gas utilities, such as Entergy and ComEd, and C&I customers, such as H-E-B and Walmart, with
approximately 50 customers in those end markets, establishing ourselves as a critical link where speed-to-power, reliability, flexibility and scale converge in our
customers’ power ecosystem. Leveraging our position as a trusted provider, we are seeking to grow our business and strengthen our financial and operating performance.
