Q1 2022 Business Updates

Advent’s Next-Generation MEAs (“Advent MEA”): On March 14, 2022, Advent announced the availability of its next-generation MEA. These MEAs have already been provided for testing to select strategic partners. The Advent MEA is currently being developed within the framework of L’Innovator, Advent’s joint development program with the U.S. Department of Energy’s Los Alamos National Laboratory, Brookhaven National Laboratory, and National Renewable Energy Laboratory. The milestones already achieved include accelerated stress testing that has confirmed the potential for significant (>5x) improvement in lifetime versus current HT-PEM MEAs, and, strong potential for 2x and 3x power density increase versus current HT-PEM MEAs. Advent is in discussions for various joint development agreements in the genset, heavy duty automotive, marine and aviation markets. Advent intends to scale-up the production capacity of the Advent MEA in the order of 100s of kilowatts (fuel cell power equivalent) per month in mid-2023 and megawatts per month by the end of 2023. Advent also intends that both its own products (SereneU, Honey Badger, MZERØ) and third-party products will be able to use the new Advent MEAs in mass-production as soon as 2024. Due to the high-temperature operation, Advent’s MEAs can work with impure hydrogen that can be reformed onboard from methanol, natural gas, and other renewable fuels. The Advent MEA is expected to redefine the MEA market globally and further validate Advent’s leading position in the electrochemistry components business.

New Membrane Electrode Assembly (“MEA”) Contracts: On February 15, 2022, Advent announced the signing of new contracts with manufacturers of clean power generation and energy storage solutions for the delivery of advanced electrochemistry components. The contracts have a combined value of $2.2 million. Advent began delivering the electrochemistry components in the fourth quarter of 2021 and deliveries are expected to continue to September 2022. The vast majority of the new business is from customers based in North America. Advent’s electrochemistry components business includes electrodes, membranes and MEAs. These components are critical for fuel cells, electrolysers, and long-duration energy storage such as flow batteries. The performance of these components defines the lifetime, efficiency, weight and ultimately, a substantial portion of the cost of the end electrochemistry products. Advent is continuously innovating in the area of electrochemical components. Advent’s electrochemistry materials R&D is based in Boston, Massachusetts, with synthesis and manufacturing capabilities in Europe. Advent is expanding its production capabilities through the development of a new facility at the Hood Park campus in Charlestown, Massachusetts, which will focus primarily on the development and production of the next-generation of fuel cell components.

Distribution and Service Agreement with Calscan Solutions (“Calscan”): On January 10, 2022, Advent announced that it signed a distribution and service agreement with Calscan, a Canadian industrial service company focused in the oil field industry with a number of products, including methane emissions mitigation instrumentation and controls, as well as services including test data processing, rentals, repair, and data processing. The agreement details Calscan’s plans to market, resell, install, and service the Advent M-ZERØ^™ and SereneU fuel cell products to address the demand for electric systems in the oil and gas sector. Current regulatory pressure is focused on targets which will aggressively reduce oil and gas industry methane emissions throughout Canada. Advent’s product portfolio, including the M-ZERØ^™ and SereneU fuel cell products, aim to drop wellhead methane emissions to zero, increase well productivity and safety, and decrease maintenance costs in North American well sites. Advent’s products realize a significant carbon advantage over conventional diesel remote power generation technology and can be deployed in more extreme environments than solar panels and electric battery systems. The Advent M-ZERØ^™can also work with current systems to enhance their reliability and ensure that systems continue to operate, creating additional value-added opportunities for customers. The Advent M-ZERØ^™ products, designed specifically to generate power in remote environments, will offer the ability to drop methane emissions to effectively zero where they replace methane polluting pneumatic injection technology. The overall methane emissions related to wellheads approaches 40 million tons of carbon dioxide emissions per year, which is equivalent to the carbon footprint of more than eight million passenger cars. M-ZERØ^™ will initially be featured mainly in Canada and the United States with the aim of providing remote power to up to 185,000 oil and gas wellheads.

Upgrade of Globe Telecom, Inc. (“Globe”) sites: On January 18, 2022, Advent announced that, within the framework of its long-lasting collaboration with Globe, it is upgrading various sites for Globe in the Philippines with 10kW SereneU fuel cell systems, enabling Globe to reach its ambitious targets for reduced CO2 emissions. By deploying Advent’s SereneU fuel cells, Globe aims to reduce carbon emissions across its network, consume cleaner fuel in smaller quantities, achieve lower emissions, and maintain energy-efficient heat removal. Advent’s SereneU fuel cells produce fewer emissions than traditional generator sets, and operate almost silently, thereby providing a system with a low footprint to surrounding areas and communities. Depending on the fuels used, the systems can become close to CO2 neutral, as well as being easier to store and transport. Advent’s SereneU systems also have higher temperature and environmental conditions tolerance, ensuring uninterrupted back-up power and stronger resilience against extreme environments such as typhoons, monsoon rains, and even long dry seasons. By using fuel cells in its green transition, Globe complies not only with regulations and its own ambitions for best environmental practices but also secures several competitive advantages. Globe’s commitment to establishing science-based targets and net-zero emissions by 2050 is in line with the Paris Agreement and #RacetoZero. The Paris Agreement aims to limit global warming to 1.5 degrees Celsius compared to pre-industrial levels. #RacetoZero is the UN-backed global campaign rallying non-state stakeholders to take rigorous and immediate action to halve global emissions by 2030 and deliver a net zero-carbon emitting world by 2050. All of Globe’s initiatives in the green transition reflect its commitment to the UN’s Sustainable Development Goals (SDG), including SDG 12 “Sustainable Consumption and Production”, which relates to achieving economic growth and sustainable development by urgently reducing the ecological footprint.

Memorandum of Understanding (“MoU”) with Electric Ship Facilities B.V. (“ESF”): On February 23, 2022, Advent announced the signing of a MoU with ESF, a Dutch based business with over 15 years of experience in electric and hybrid propulsion systems and energy systems for recreational and commercial purposes. Under the agreement, ESF commits to becoming a future distributor of Advent’s SereneU fuel cell products, further strengthening its portfolio of innovative CO2 reducing technologies. ESF offers demonstrations and state-of-the-art components, helping its customers significantly reduce emissions and achieve energy efficiency. This new collaboration will enable Advent to facilitate trial processes and fuel cell configurations for both land-based and maritime applications, with the initial geographic focus being Benelux, Germany, Switzerland and Austria. Advent’s SereneU fuel cells are currently being used for demonstrations within the framework of the Green Shipping Wadden Sea Program, an initiative coordinated by FME (a Dutch association of enterprises in the industrial sector), having ESF as one of its founding companies. The Green Shipping Wadden Sea Program aims to accelerate innovations in the field of CO2-neutral and fossil-free shipping for the Wadden Sea fleet, as well as to develop the associated port facilities and infrastructure, and to secure governmental pathways promoting the transition towards innovative CO2 reducing technologies.

Preliminary Strategic Agreement with Daiden Equipment Sdn Bhd (“Daiden”): On March 17, 2022, Advent announced that it entered into a preliminary strategic agreement with Daiden, a leading power generation and industrial equipment provider in Malaysia. Daiden has declared its intention to become a distributor of Advent’s SereneU fuel cell products. This will enhance the promotion of Daiden’s clean power generation sources and actively support the ongoing green energy transition efforts in Malaysia. Advent has already shipped units of its SereneU fuel cell products to Daiden for testing and evaluation. Once these tests have been completed, Daiden and Advent will determine the best strategic approach for the introduction of Advent’s methanol-based fuel cells to the Malaysian market.

Dr. Gregoriou concluded, “Advent made significant progress during 2021, and in this time we strengthened our technology position and augmented our product offering. This growth strategy has now started to bear fruit in 2022, reflected by strong customer interest in our technology and product portfolio, and, a growing pipeline. We will continue to consolidate our business with a view to maximizing efficiency and effectiveness throughout our global operations, and to focus on core markets and significant projects. The White Dragon and Green HiPo projects are progressing and we believe that, if approved, each will have a significant impact on the implementation of green energy in Europe, shifting power generation and reliability away from traditional fuel sources. I remain confident in the potential of Advent and our technology, and I am very optimistic that we will continue to increase market share as economies embrace clean energy and decarbonization.”

Supplemental Non-GAAP Measures and Reconciliations

In addition to providing measures prepared in accordance with GAAP, we present certain supplemental non-GAAP measures. These measures are EBITDA, Adjusted EBITDA and Adjusted Net Income / (Loss), which we use to evaluate our operating performance, for business planning purposes and to measure our performance relative to that of our peers. These non-GAAP measures do not have any standardized meaning prescribed by GAAP and therefore may differ from similar measures presented by other companies and may not be comparable to other similarly titled measures. We believe these measures are useful in evaluating the operating performance of the Company’s ongoing business. These measures should be considered in addition to, and not as a substitute for net income, operating expense and income, cash flows and other measures of financial performance and liquidity reported in accordance with GAAP. The calculation of these non-GAAP measures has been made on a consistent basis for all periods presented.

EBITDA and Adjusted EBITDA

These supplemental non-GAAP measures are provided to assist readers in determining our operating performance. We believe this measure is useful in assessing performance and highlighting trends on an overall basis. We also believe EBITDA and Adjusted EBITDA are frequently used by securities analysts and investors when comparing our results with those of other companies. EBITDA differs from the most comparable GAAP measure, net income / (loss), primarily because it does not include interest, income taxes, depreciation of property, plant and equipment, and amortization of intangible assets. Adjusted EBITDA adjusts EBITDA for transactional gains and losses, asset impairment charges, finance and other income and acquisition costs.

The following tables show a reconciliation of net income / (loss) to EBITDA and Adjusted EBITDA for the three months ended March 31, 2022 and 2021.

EBITDA and Adjusted EBITDA	Three months ended March 31, (Unaudited)

Adjusted Net Income / (Loss)

This supplemental non-GAAP measure is provided to assist readers in determining our financial performance. We believe this measure is useful in assessing our actual performance by adjusting our results from continuing operations for changes in warrant liability and one-time transaction costs. Adjusted Net Loss differs from the most comparable GAAP measure, net income / (loss), primarily because it does not include one-time transaction costs and warrant liability changes. The following table shows a reconciliation of net income / (loss) for the three months ended March 31, 2022 and 2021.

Adjusted Net Loss	Three months ended March 31, (Unaudited)
