First Hydrogen Adds Mobile AI-Driven Robotic Ground Drone Platform

Vancouver, British Columbia--(Newsfile Corp. - March 26, 2026) - First Hydrogen Corp. (TSXV: FHYD) (OTC Pink: FHYDF) (FSE: FIT) ("FIRST HYDROGEN" or the "Company")  announces that further to the February 23, 2026 news release, the Company has amended and expanded the binding Letter of Intent (the "LOI") with Exodus Actuation Solutions Inc. ("RoboticsCo") to include exclusive worldwide rights to develop and advance a patented mobile robotic unmanned ground vehicle (the "UGV") designed for autonomous and remote robotic operations. Unmanned Ground Vehicles are considered ground-based drones, operating without an onboard human through remote control or autonomous systems to handle security surveillance, AI enabled ground military operations, dangerous sites or load management on land. Artificial Intelligence is rapidly transforming ground-based drone defense systems (Counter-Unmanned Aircraft Systems) from passive monitoring tools into active, autonomous, and rapid-response networks. Key applications include AI-driven sensor fusion, target recognition, and autonomous interception to combat the increasing threat of drone swarms and high-speed threats.

The UGV will be powered by a hybrid design with solar, battery and hydrogen fuel cell delivering extended runtime, low noise operation and zero-emission. The UGV will be built on a durable modular chassis which is usable in any terrain and designed to support a wide range of payloads. It will feature eight articulated semi-robotic legs equipped with integrated leg-wheel assemblies. The hybrid leg-wheel architecture allows the platform to roll efficiently on smooth surfaces while maintaining the stability of continuous 4-point contact, with the traction and terrain-handling capability of a legged robot. This design enables the UGV to efficiently navigate uneven environments where conventional wheeled or tracked carts and delivery robots often struggle.

Drones as a Service ("DaaS") is an on-demand or subscription-based model that allows businesses to leverage aerial and ground drone technology, including hardware, software, and certified pilots, without the high capital expenditure of purchasing and maintaining the equipment themselves. This model is rapidly expanding to provide tailored solutions for agriculture, military, construction, and infrastructure monitoring. Precedence Research reports that the current drone services market is valued at US$20.2 billion estimated to grow at a CAGR of 24.04% to US$142.2 billion by 2035. With global defense spending exceeding $2 trillion annually, growing interest in robotic systems for logistics, inspection, and hazardous operations could represent a significant driver of future robotics deployment.

Mounted above the robotic chassis is a modular cargo platform with multiple versatile applications that are easily interchangeable. The functions are designed for military field support such a drone launch and refueling platform, transport, equipment, security, tools, emergency packages, or other heavy items. The system is intended to function as a mobile robotic drone assistant capable in a wide range of logistics, such as campus and facility operations including security, construction sites, and last-mile delivery and emergency situations.

The platform is expected to support both autonomous and user-assisted operating modes, allowing the robot to follow a user, operate via remote control, or navigate predetermined routes. By combining robotic mobility with cargo transport capability, the system aims to reduce manual labour requirements and reduce power consumption in environments where materials must be moved frequently across varying terrain. The useful platform allows for use in academic research, industrial automation, defense research programs, and autonomous navigation testing.

Balraj Mann, CEO of First Hydrogen commented: "We believe hybrid robotic mobility platforms represent an emerging category within the broader robotics and automation sector, enabling new applications in logistics, infrastructure maintenance, and industrial & defense operations. The UGV drone strategy of Drones-as-a-Service builds on the Company's hydrogen-as-service business model."

The Company will have exclusive worldwide rights to advance the UGV towards commercialization, including the development of a viable commercial design and defined application for the technology within a two year period ("Development Milestone"). Upon successful completion of the Development Milestone First Hydrogen shall have exclusive worldwide rights from the remaining life of the UGV patent to develop, commercialize and exploit the UGV, subject to a 1% royalty on gross sales of products the incorporate the UGV patent. First Hydrogen will bear all cost of development and will own 100% of the intellectual property, inventions, developments, improvements, products, software, designs, data, know-how, and other work product created, conceived, or developed in connection with the UGV.
