favorably with such technology as our power systems are lower cost, faster starting and provide low variation in electrical voltage and frequency using a rich-burn combustion process that eliminates the costly addition of selective catalytic reduction systems for emissions control or battery energy storage for power quality management. • Small gas turbines (3-30 MW) . Small-scale gas turbines operate on carbon-based fuels such as natural gas or diesel and offer high power density but often have slower start times, efficiency losses from altitude and temperature conditions and long procurement and permitting cycles, making them less suited for fast-response distributed applications requiring modular scalability. Such turbines also often require greater equipment redundancy to achieve comparable availability for large data-center and other mission-critical customers. We believe we compete favorably with such technology as our power systems provide faster starting, better voltage and frequency management, and do not require high Table of Contents

pressure fuel supply for operations, which enables faster construction cycles since distribution pressure gas are more common near customer facilities.

• Traditional backup equipment . Traditional backup systems, such as diesel generators, are common for
serving customers during grid outages, but face increasingly restrictive emissions limits, fuel supply-chain vulnerabilities during disasters and provide limited to no economic value outside rare outage events. We believe we compete favorably with
such technology as our power systems provide multiple value stream including backup and grid stabilization services and match technical performance of diesel backup generation without the noise, emissions, and vulnerability to over the road fuel
deliveries during emergencies.

• Commercially available fuel cells . There are a variety of commercially available fuel cells capable of
providing energy storage as a power source, including proton exchange membrane fuel cells, molten carbonate fuel cells, phosphoric acid fuel cells and solid oxide fuel cells. Commercial fuel cells can offer low-emission baseload power but typically
involve higher capital expenditures, limited transient response, and significant ongoing maintenance costs, reducing their suitability for large-scale resiliency or fast-response dispatch applications. We believe we compete favorably with such
technology as our power systems are lower cost, have higher power density to reduce space requirements, are fast starting and can ramp to follow loads, while maintaining low variability in voltage and frequency.

• Combined-cycle plants . Combined-cycle facilities use both gas and steam turbines to increase total
electrical output from the same fuel input. While efficient at utility scale, these plants are not designed for onsite resiliency, rapid deployment or customer-specific load support. Accordingly, these plants achieve high fuel efficiency but are
large, long-dated utility assets that do not address customer-level resiliency, speed-to-power or behind-the-meter load support needs. We believe we compete favorably with such technology as our power systems can deploy much faster in 18-24 months and can provide much faster starting operation to meet backup power requirements and support grid emergencies.

• Traditional co-generation systems . These systems deliver a
combination of electric power and heat and are optimized for facilities with constant thermal loads and therefore struggle to provide flexible, high-availability electric capacity required for data center and industrial customers. We believe we
compete favorably with such technology as our power systems are designed to provide grid stability and backup services sized to meet the electrical requirements of the customer, without the added cost and requirements of thermal heat recovery and
distribution.

• Utility scale simple cycle gas turbines . These very large turbines are designed to serve the ISO or the
broader grid rather than individual customer facilities and cannot address customer-specific reliability, speed-to-power requirements or transmission and distribution cost avoidance opportunities. We believe we compete favorably with such technology
as our power systems are modular for faster deployment and can be located at or behind the customer meter to provide the same grid stabilization services, but with faster start times and without the dependency on grid interconnection queues, and the
resulting grid upgrade costs.

• Battery storage . There are a variety of commercially available energy storage solution products capable
of providing energy storage as a power source. Battery storage is effective for short-duration time shifting of loads but cannot cost-effectively deliver multi-hour to multi-day firm capacity or support large loads during extended outages or grid
emergencies without substantial and expensive oversizing and the resulting space requirements. We believe we compete favorably with such technology as our power systems provide fast start energy generation without duration limits due to continuous
fuel supply from the underground gas pipelines network.

• Alternative power generation. We also compete with producers of renewable power combined with battery
storage solutions, geothermal power solutions, and emerging modular nuclear power solutions. Such alternative generation technologies face constraints such as intermittency, specialized siting requirements, or long development timelines, making them
less able to meet near-term onsite resiliency

and speed-to-power needs. We believe we compete favorably with such technology, and in some cases can supplement existing operations, as our power systems can provide firm, dispatchable capacity
that matches the full load requirements of our customers and require much less space.

Our key
competitors include other distributed energy generation system vendors such as Bloom Energy Corporation, Caterpillar Inc., Cummins Inc., GE Vernova Inc., Generac Holdings Inc., INNIO, PowerSecure, Siemens AG, Volta Grid LLC and Wärtsilä
Corporation. Battery companies such as Fluence Energy, Inc. and Tesla, Inc. also provide systems that may act as a limited replacement for our systems and also have energy management software. Some of our current and potential competitors have
longer operating histories and greater financial, technical, marketing and other resources than we do. These factors may allow our competitors to respond more quickly or efficiently than we can to new or emerging technologies. These competitors may
engage in more extensive research and development efforts, undertake more far-reaching marketing campaigns and adopt more aggressive pricing policies, which may allow them to more effectively compete for new
power system projects.

Research and Development

To maintain our competitive edge, we are advancing a robust R&D pipeline designed to enhance core generator and software
technology offering and expand into new energy solutions that meet evolving customer needs. Our roadmap builds on the success of our RockBlock systems, with the goal of delivering greater reliability, simplified installation and improved operational
flexibility, integration with other onsite energy technologies, such as battery energy storage systems, as well as additional, complementary products. A key focus is the continued evolution of Granite, with the goal of delivering higher reliability
through predictive diagnostics, preventive maintenance, lowered cost and dynamic integration of distributed assets into a unified system. These innovations are intended to allow customers to optimize performance, reduce operating costs, and
accelerate deployment timelines, while positioning ERock as a leader in scalable, intelligent power solutions for the future.

Intellectual
Property

We rely on patents, trade secrets, copyrights and other forms of intellectual property protection, both
internally developed and acquired, in order to maintain a competitive advantage and protect our freedom to operate. Our products are manufactured, marketed and sold using a portfolio of patents, trade secrets, copyrights and other forms of
intellectual property, some of which have statutorily limited terms and will expire in the future. We seek to develop and acquire new intellectual property on an ongoing basis. Based on the broad scope of our product lines, we believe that the loss
or expiration of any single intellectual property right would not have a material effect on our consolidated financial statements.

As of December 31, 2025, a majority of our intellectual property consists of proprietary know-how, processes and other
confidential information that we protect primarily as trade secrets using contractual confidentiality obligations. We own one issued patent covering our generator in the United States that will expire in 2036, and we own a similar patent in 16 other
national jurisdictions. As of December 31, 2025, we own 61 registered trademarks and 20 applied-for trademark applications, for which certain rights are dependent on the registration of the trademark by
the U.S. Patent and Trademark Office or other applicable national or regional trademark authority. As of December 31, 2025, we own several registered domain names, with the primary registered domain name used in our business being for our
website, www.enchantedrock.com. The reference to our website is an inactive textual reference only and information contained therein or connected thereto is not incorporated into this prospectus or the registration statement of which it forms a
part.
