First Half and Second Quarter 2021 Highlights

Recent Business Highlights

ROCHESTER, NY, August 11, 2021 – Hyzon Motors Inc. (NASDAQ: HYZN) (“Hyzon” or the “Company”), a leading global supplier of zero-emission fuel cell electric heavy vehicles, today announced second quarter 2021 financial results.

“During the second quarter we achieved significant milestones for Hyzon. We advanced our business objectives, expanded our partnerships, grew our world-class team, and increased the number of contracted customers to further our efforts in the global adoption of hydrogen in commercial transport,” said Craig Knight, Chief Executive Officer of Hyzon. “Shortly after the close of the second quarter, we completed our business combination and we currently have over $500 million of cash on the balance sheet as a result, which we expect to help accelerate our growth, meet customer demands, and enable us to expand our teams and operations globally.”

Following the close of the second quarter, Hyzon Motors USA Inc. (f/k/a Hyzon Motors Inc.) successfully completed its planned business combination with Decarbonization Plus Acquisition Corporation (“DCRB”) on July 16, 2021. With 94.8% of the shares of DCRB having voted in favor of the business combination, and only 7.4% of common shares electing to redeem shares for cash, the combination resulted in a primary capital raise of $559 million for Hyzon, before transaction expenses. “This remarkable achievement of closing our transaction with such overwhelming support from DCRB shareholders was both a validation of our strategy and an investment in our future,” continued Mr. Knight.

Between announcing and closing the business combination, Hyzon executed a number of memoranda of understanding (MOUs) and purchase orders with a growing roster of global industrial, commercial and transportation counterparties, including: Superior Pak (Australia/New Zealand), Coregas, subsidiary of Wesfarmers (Australia), FrieslandCampina (The Netherlands), TotalEnergies (France), MPREIS (Austria), John G Russell (United Kingdom), ARK Energy, subsidiary of Sun Metals (Australia), Chart Industries (North America), Fortescue Metals Group (Australia), Sojitz Machinery Corporation of America (North America), JuVe Automotion (Europe), and NEOM (Middle East / North Africa). The Company also advanced its pipeline with numerous municipalities across the globe, strengthened alliances with industry leaders in the hydrogen ecosystem, and announced a number of technical milestones that are rapidly advancing total cost of ownership (TCO) parity and performance superiority for Hyzon’s products more quickly than originally envisioned.

“Hyzon’s strategy remains firmly rooted as a business built around a defined and already commercialized technology that is the product of years of investment with customer uptake that is both global in reach and accelerating in pace. Our sales pipeline is

proof that the world is truly recognizing the need to seek out immediate solutions to mitigate climate change, thereby accelerating efforts to move the world economy down the path to net-zero emissions. We are the company providing hydrogen solutions today for commercial, heavy-duty, high-utilization transportation use cases, and we could not be more excited as the opportunity set for our offerings grows daily. Particularly following the recent IPCC Sixth Assessment and escalating investor attention to ESG focused opportunities, the backdrop for Hyzon’s business has never been stronger.” concluded Mr. Knight.

Use of Non-GAAP Financial Information

To supplement its condensed consolidated balance sheet and statement of operations and comprehensive loss, which are prepared and presented in accordance with U.S. generally accepted accounting principles (“GAAP”), Hyzon Motors Inc. reports EBITDA and Adjusted EBITDA which are non-GAAP financial measures. EBITDA is determined by taking net income and adding interest, depreciation and amortization. Adjusted EBITDA is determined by taking EBITDA and adding non-cash stock-based compensation expense and other special items determined by management. We believe that these non-GAAP measures, viewed in addition to and not in lieu of our reported GAAP results, provides useful information to investors by providing a more focused measure of operating results, enhances the overall understanding of past financial performance and future prospects, and allows for greater transparency with respect to key metrics used by management in its financial and operational decision making. The non-GAAP measures presented herein may not be comparable to similarly titled measures presented by other companies. EBITDA and Adjusted EBITDA has been reconciled to the nearest GAAP measure in the tables within-this press release.
