Contents 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.”

Rapid Deployment of Reliable,
Dispatchable Power

We offer a rapid path to connect large electricity loads, such as data centers and C&I
customer manufacturing facilities, to power. Our power systems enable customers to quickly deploy a distributed bridge 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.

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.
