Electrification of transportation has enormous tailwinds The transportation sector is responsible for one-quarter of all global greenhouse emissions globally.1 Transforming today's fleets and fuels to zero-emission is a priority for policymakers, manufacturers, and consumers. More than 70countries, including the biggest polluters – China, the United States, and the European Union – have set a net-zero target, covering 76% of global emissions.2 Policymakers 75% of the off-highway vehicle (OHV) sector says their company either will or might pursue electrification.3 Corporations 52% of car buyers globally now want to purchase an electric vehicle, a rise of 22% in just two years.4 Consumers 1 “Fact Sheet Climate Change - Un.org,” accessed March 5, 2023. 2 “Net Zero Coalition,” United Nations (United Nations), accessed March 4, 2023. 3 Waytek. “State of Electrification Report 2019.” 2019. 4 Lewis, Micah. “In a Global Tipping Point, 52% of Car Buyers Now Want to Purchase an EV – Here’s Why.” Electrek.

Copyright © 2023 ZeroNox®. All rights reserved. Pain points in the value chain slow OEM electrification Manufacturers lack the expertise to custom design EV components to specifications, hindering the development of new electric models. The transition to EVs can require significant capital investments and time-intensive manufacturing processes, which can strain manufacturers' resources. To deploy and distribute electric vehicles at scale, a robust EV infrastructure is needed, including renewable microgrids, energy storage, and charging stations. Manufacturers transitioning to EVs need renewed distribution channels targeting both opportunistic and underserved markets. A lack of specialized technicians and EV expertise, as well as limited geographic availability, can hinder the adoption and maintenance of EVs. ~16MM workers needing clean tech upskilling for the economy to transition to Net Zero by 20505 $1-2BN the average cost of building a new EV factory6 <5% of the estimated 1.2 million public charging stations needed by 20307 are currently available8 ~1% was the portion of the global vehicle stock that was electric in 20209 84% of technicians in the U.K. are currently unqualified to safely work on electric vehicles10 Design Development Infrastructure Distribution Service ZeroNox’s products and go-to-market strategy solve these pain points across the value chain and unlock nationwide and global scale 5 International Energy Agency (IEA)., “Overview – World Energy Employment – Analysis,” IEA. 6 The New York Times. “General Motors to Spend $7 Billion on Electric Vehicle Plants.” January 25, 2022. 7 USAFacts. “How Many Electric Vehicle Charging Stations Are There in the US?” November 23, 2022. 8 McKinsey & Company. “Charging for Charges.” June 24, 2022. 9 International Energy Agency (IEA). “Global EV Outlook 2021.” 10 José Rodríguez Jr., “A Looming Skills Gap Suggests There Are Not Enough EV Mechanics,” Jalopnik (Jalopnik, February 28, 2023). 5
