- 7. 4/11/2023 7 © INDIUM CORPORATION IPC APEX EXPO 2023 FACTOIDS as of Feb 2023 • >40% of U.S. households do not have access to convenient overnight charging. • >97% uptime performance required of public chargers receiving public money. (1) • >55% of the cost of content must be US sourced for public chargers receiving public money. (1) • 130K of US public chargers have 78.6% uptime performance as of end of 2022. (1,2) • Electronics are a significant contributor to field failures. (3) • Electronics in US public chargers are built today to similar standards as consumer electronics (ex: Microwave Oven). • 1-3 years average warranty (compare to average automotive warranty 3-5 years). • Mexico, China, Vietnam, etc. manufactured electronics for the US market shifting to US factories.

- 15. 4/11/2023 15 © INDIUM CORPORATION IPC APEX EXPO 2023 Get Ready for 1500v and Beyond! • EV inverters already handle higher voltages than other electronics • The desire for fast charging is pushing these applications to higher and higher voltages • Charging stations and BESS (Battery Energy Storage Systems) are becoming a crucial part of the infrastructure needed and will require even higher voltages
- 16. 4/11/2023 16 © INDIUM CORPORATION IPC APEX EXPO 2023 Top OEM Challenges • Electronic assemblies working harder, longer and at higher operating temperatures (i.e. longer mission profiles and higher voltage) • More electronics packed into smaller formfactor • Proliferation of cutting-edge technologies into e-Mobility • Time to market - Shorter development cycles • Supply Chain Bottlenecks & lack of “older” components • Lack of Industry standards • Finding Talent 16
