Our Company Overview We are an advanced materials and technology development company operating in the fuel cell and hydrogen technology space, including liquid hydrogen carriers such as methanol. We are a world-leading company in the development of HT-PEM (High Temperature Proton Exchange Membrane) technology (with approximately 150 patents issued, pending, or licensed worldwide). The HT-PEM fuel cell technology enables off-grid power systems to produce clean power from various green fuels (hydrogen, methanol, bio and e-Methanol, and renewable natural gas) and to function with higher efficiency at extreme ambient temperatures and in general extreme environmental conditions (hu
Business
Business Strengths Highly Differentiated Technology : We believe that for the reasons explained above, HT-PEM is a highly differentiated technology that provides significant competitive advantages to Advent and our partners. HT-PEM technology is a new and promising technology when compared to LT-PEM (Low Temperature Proton Exchange Membrane), that was developed for the last 50 years and may have plateaued in terms of expected technology breakthroughs needed to overcome thermal control and environmental limitations. Experienced management team with a proven track record : We were founded and managed by world-class electrochemists, material scientists, and fuel cell specialists with significant industry and manufacturing expertise. We have received numerous R&D funds from the US DoE and the European Union and are considered a pioneer with years of experience in clean energy technology innovation. The team that we have recruited to bring innovation to the fuel cell industry is highly experienced and has a long pedigree in R&D and world-class manufacturing. Our team has been developing MEA components since 2006 and is led by Dr. Emory De Castro (CTO). Strategic Partnership with US DoE and Los Alamos National Laboratories : In addition, we initiated in 2021 a Cooperative Research and Development Agreement (CRADA) under the U.S. Department of Energy ("DoE") umbrella to commercialize next-generation MEAs and ultra-low platinum catalyst solutions developed by the National Laboratories at Los Alamos, Brookhaven, and NREL, in the U.S. We were selected as the scale-up and commercialization partner of the DoE and are working closely with the highly-skilled R&D teams of top U.S. government laboratories. MEA IP and Technology : We firmly believe in the transformative potential of the Advent MEA to redefine the global fuel cell market, enabling applications that were previously unattainable with conventional fuel cell materials. Our objective is to enhance the MEA's capabi
Business
Business Strategy Our growth strategy is focused on targeting the following four sectors: The stationary off-grid market is expected to be a growing market. The large-scale fuel cell systems market (power generation, data centers and power to gas). The human-portable defense, surveillance, energy infrastructure, and leisure market based on our innovative Honey Badger products. The development of next-generation MEA and fuel cell solutions for the mobility market. 3 Table of Contents Our approach extends beyond direct sales; we actively supply our membrane electrode assemblies (MEAs) to other fuel cell manufacturers, and we intend to supply core technology through technology transfer agreements to OEMs. This serves as a cornerstone for our expansion plans, focusing on scaling up through the licensing of our technology. Central to our strategy for future growth is the emphasis on licensing agreements with large-scale manufacturers possessing market access and robust service, support, and capital expenditure capabilities. Through partnerships with Tier1s and OEMs, we empower our collaborators to innovate and commercialize fuel cell systems powered by Advent's proprietary technology on a significant scale. Our collaborators actively manage the entire value chain, including sales, marketing, and after-sales service. Until these partnerships mature and reach the mass manufacturing stage, we derive revenues from major partners through Joint Development Agreements, which are pivotal in financing the early stages of market-specific product development. As our business ramps up to mass production, we plan to pursue a revenue model that includes fuel cell system sales, MEA sales, and hardware-technology licensing fees. Our customer relationship is split into two phases: 1) partner with OEMs to co-develop customized fuel cell systems based on our expertise in MEAs and HT-PEM fuel cell systems. During the product development phase, we earn engineering fees, and
