Texas already shows rapid load growth pressures tied to data centers and industrial expansion, while California faces grid congestion, long interconnection queues and above-average vulnerability to extreme heat and weather-driven outages. Additionally, supply-chains for critical grid components are showing strain. GE Vernova, Siemens Energy and Mitsubishi Power, which supply turbines for roughly two-thirds of the gas-fired power plants under construction globally, as reported by the IEA, are facing extensive backlogs and turbine delivery timelines of as long as eight years according to the Institute for Energy Economics and Financial Analysis. The IEA highlights that order backlogs for transformers grew by more than 30% in 2024, after two years of growth above 15%. In combination with these pressures, the current market dynamics illustrate a growing divergence between the rapid acceleration of load growth and the comparatively slow pace of utility-scale infrastructure development.

We are well positioned to deliver on the significant market demand for dispatchable, resilient and cost-effective power
solutions that can be quickly deployed and commissioned. Through delivering 99.999% reliability and the capability to deliver in less than six months, with full project commissioning typically achieved within 12 to 18 months from contract signing,
we provide one of the few scalable solutions capable of addressing near-term capacity needs, particularly in high-growth regions like Texas and California. As natural
gas remains a critical firm resource supporting renewable integration, our modular, low-emission solutions enable hyperscale data centers, industrial facilities and utilities to procure reliable, firm power at substantial scale, often reaching
several hundred megawatts or over a gigawatt, without the prolonged lead times inherent in traditional transmission expansion. This combination of speed, reliability and flexibility positions us to capture significant share in an increasingly capacity-constrained U.S. power market.

Our Power System Solutions

We are uniquely positioned to address the massive, fast-growing and complex market for speed-to-power, dispatchable capacity and resiliency solutions. Our power systems are delivered through our ERock Platform, which provides our customers a single partner across the entire life cycle of our
power systems and differentiates us from our competitors. Our ERock Platform is anchored by leading natural gas engine and generator technology for multi-function onsite generation and combines this core technology with comprehensive, turnkey ESI
services—a full-service offering that includes system design, site selection, planning and modeling, interconnection assistance, gas supply, permitting, construction and commissioning. Once operational, our ERock Platform offers O&M and
dispatch capabilities that leverage extensive historical operational data capture, real-time monitoring and predictive diagnostics to optimize power system performance, while our remote operations center enables asset-level or aggregated dispatch,
scheduled maintenance coordination and electricity and gas market integration to help maximize the value customers can capture using these systems. These integrated solutions and capabilities allow our power systems to be rapidly deployed, serve
initial bridge power needs and, after grid interconnection, provide dispatchable capacity and/or reliable long-duration backup power throughout the remaining useful life of our systems, as discussed below. For more information regarding the services
delivered through our ERock Platform, see “—Our Services.”

power solution that provides faster access to reliable power through and beyond full grid interconnection. We have assembled and delivered our power systems in as little as six months, with full
project commissioning typically achieved within 12 to 18 months from contract signing. We also have a track record of interconnecting multiple >50MW systems in 12 to 18 months from contract signing, subject to site conditions. Leveraging our
high-volume standardized assembly model, we can stand up over 1.2 GW of annual available capacity in approximately 12 months with limited incremental capital expenditures.

Our rapid deployment capability supports businesses and utilities seeking cost-effective power continuity and resilience in an
increasingly dynamic energy landscape and enables customers to access power during lengthy utility interconnection timelines to maintain project schedules. At up to two times the cost of our power systems, traditional and bespoke natural gas
generation projects can take 60 to 84 months to deploy. At up to three times the cost of our power systems, natural gas fuel cells lack the dispatch capability of our power systems and typically have larger footprints, which can impact installation
timelines. Solar and wind projects often require three years or more to deploy and are not capable of delivering reliable, dispatchable power like our power systems due to the inherent intermittency of sun and wind power sources. Even when paired
with batteries, solar and wind remain limited in their ability 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.
