Coates Stock Price, News & Analysis

Coates International, Ltd. (COTE) is a technology company in the producer manufacturing sector with activities connected to trucks, construction, and farm machinery. According to company information, it focuses on the design, development, and application of proprietary engine and green hydrogen technologies. The firm was founded on December 22, 1987 and is headquartered in Wall Township, New Jersey.

The company’s historic core technology is the Coates Spherical Rotary Valve (CSRV) system, a patented valve mechanism designed to operate in piston-driven internal combustion engines. This system has been described as suitable for many types of engines and applications, including automobiles, light trucks, heavy trucks, machinery, railroads, marine engines, military equipment, light aircraft, helicopters, lawn mowers, snowmobiles, and jet skis. Over time, Coates International, Ltd. has expanded its focus to green energy power generation and hydrogen-based systems built around its CSRV engines.

Green hydrogen and CSRV generator technologies

Company releases state that Coates International, Ltd. has invested substantial resources in research and development of green hydrogen technologies. The firm reports that it has designed and built several related systems, including:

• CSRV industrial generator engines configured for green applications.
• A sequential multi-fuel injection system for hydrogen, natural gas, propane, and other engine fuels.
• The Coates Hydrogen (H2) Reactor and what it describes as its most advanced Green Hydrogen Atomic Reactor, designed to produce gaseous hydrogen from ordinary water or sea water while using a small portion of the generator’s output.
• The Coates Magnetized Charcoal Ambient Air Cleaning System, described as being in the patenting process.
• The Coates Internal Turbine Windvane, also reported to be in the patenting process.

According to the company, its hydrogen reactor systems are intended to be coupled with CSRV industrial electric power generator-sets in various power ratings. Company statements emphasize testing on combinations such as diesel plus hydrogen and natural gas plus hydrogen for industrial electric power generation. Coates International, Ltd. has reported independent testing of its hydrogen reactors and generator systems, with results it characterizes as meeting or exceeding its expectations.

Applications and market focus

Based on company disclosures, Coates International, Ltd. positions its technologies for industrial electric power generation and heavy-duty engine applications. The CSRV engines and hydrogen reactors are described as suitable for use with industrial generator-sets and potentially adaptable to large trucks, buses, ships, boats, and existing generator substations. The company has also mentioned the potential to assist charging stations for electric power vehicles by supplying electric power from its generator systems.

Public communications from Coates International, Ltd. indicate that it has received firm orders and license commitments for its hydrogen-based generator technologies and has engaged in negotiations for manufacturing and distribution rights in multiple regions. The firm has reported license agreements granting rights to manufacture, use, and sell its patented green electric power generators and hydrogen reactors in the European Union, and it has described discussions with a Mexico-based manufacturer regarding production and distribution in Mexico and South America.

Licensing and international manufacturing plans

According to its press releases, Coates International, Ltd. and Advanced Hydrogen Power, Ltd. have signed a license agreement with a company in the European Union. This agreement grants rights to manufacture, use, and sell Coates patented green electric power generators and hydrogen reactors throughout the European Union. The company has stated that manufacturing operations for these products are planned to be established in Poland, with Coates supplying components, parts, and technical drawings and coordinating with local engineers.

The company has also reported that it is in the process of selling a license to a Mexico-based manufacturer to produce and distribute Coates electric power generators and hydrogen reactors in Mexico and South America. Representatives of this manufacturer have, according to Coates, conducted on-site inspections and independent tests at the Coates facility in New Jersey.

Research, development, and intellectual property

Coates International, Ltd. states that it has spent many years in research and development and has invested significant funds in the design of its green technology products. The company reports that it has already been awarded many patents, with additional patents in process, covering its CSRV engines, hydrogen reactors, multi-fuel injection systems, and related technologies. It describes its hydrogen and CSRV technologies as advanced and emphasizes that they are designed to operate without storing hydrogen, instead using hydrogen as it is produced.

Company communications also highlight ongoing R&D efforts aimed at systems that produce gaseous hydrogen from water or sea water, with the goal of reducing the energy required from the generator-set. Coates International, Ltd. has described work on a separate system intended to produce gaseous hydrogen without drawing power from the CSRV generator, with the stated objective of producing electric power at very low cost and with low emissions.

Capital raising and corporate developments

In its public updates, Coates International, Ltd. has discussed private placement offerings and contemplated private offerings to accredited investors. The company has described raising capital to support production operations and expansion of its hydrogen and CSRV technologies. It has also reported that it was planning to list its shares on an exchange and has referenced orders and license commitments related to its hydrogen products and generator-sets.

In a later development, Coates International, Ltd. disclosed that the majority owners of Coates International, Ltd. and Advanced Hydrogen Power, Ltd. signed a contractual agreement on April 2, 2025 to sell both companies and all technologies and patents to a private bank buyer for a stated total consideration. According to that announcement, the sellers and the companies were to receive specified allocations of the transaction value, and the existing majority owners were expected to remain with the companies to set up manufacturing operations. The buyer’s identity was not disclosed in the release. The company indicated that further news would follow.

Position within producer manufacturing and machinery-related markets

Within the broader producer manufacturing sector and the trucks/construction/farm machinery industry classification, Coates International, Ltd. presents itself as a developer of specialized engine and generator technologies rather than a conventional vehicle or equipment manufacturer. Its disclosures emphasize engine architecture (CSRV), hydrogen reactors, and associated systems intended for integration into industrial power generation and heavy-duty applications. The company’s communications focus on green energy, hydrogen-based fuel systems, and potential uses in sectors that require reliable industrial power and heavy machinery operation.

Key points for investors and researchers

For those analyzing COTE stock or researching Coates International, Ltd., the company’s own releases highlight several recurring themes:

• A long-standing focus on CSRV internal combustion engine technology and its adaptation to hydrogen and multi-fuel operation.
• Development of hydrogen reactors that, according to the company, produce gaseous hydrogen from water or sea water and are integrated with CSRV industrial generator-sets.
• Emphasis on green energy and low-emission power generation, with testing data and emissions figures cited in company communications.
• Use of licensing and manufacturing agreements to extend production and distribution into regions such as the European Union, Mexico, and South America, as described in its own announcements.
• Ongoing references to orders, license commitments, and production planning for industrial electric power generators and hydrogen systems.

All of the above information is based on the company’s public descriptions of its own technologies, agreements, and plans. There can be no assurance, as the company itself notes in several releases, that it will be successful in any of its endeavors.
