GORES GUGGENHEIM AND POLESTAR EXPECTED TO CLOSE BUSINESS COMBINATION ON JUNE 23, 2022

LOS ANGELES and GOTHENBURG – June 21, 2022 – Gores Guggenheim, Inc. (“Gores Guggenheim” or the “Company”) (NASDAQ: GGPI, GGPIU and GGPIW), a special purpose acquisition company sponsored by affiliates of The Gores Group, LLC and Guggenheim Capital, LLC, and Polestar, the Swedish electric performance car company, today announced they expect to close their business combination on June 23, 2022, subject to Gores Guggenheim stockholder approval.

The transaction is expected to raise at least $850 million in gross proceeds though a combination of a fully committed PIPE and cash held in trust. The cash held in trust accounts for a maximum 25% in preliminary redemption elections and assumes none of such preliminary redemption requests are withdrawn.

Alec Gores, Chairman of Gores Guggenheim, states: “To have limited redemptions in this challenging macro environment is an incredible feat and speaks to the strength of Polestar’s brand – as well as the high conviction our investors have in Polestar’s potential. We are proud of the momentum Polestar has built over the past several months and we look forward to the expected closing of our business combination this week.”

Thomas Ingenlath, CEO of Polestar, says, “Our listing on the Nasdaq in partnership with Gores Guggenheim will be a milestone moment for the company. Our team has been working hard and that work is paying off. We are excited about the future of Polestar and will continue to build world-class electric cars, grow the passionate customer community and expand into even more markets around the globe.”

The special meeting of GGPI stockholders (the “Stockholder Special Meeting”) and meeting of the Company’s warrant holders (the “Warrant Holder Meeting”) are scheduled to occur on June 22, 2022. The Stockholder Special Meeting will be held via live webcast at www.meetnow.global/MYGAWFM on June 22, 2022, at 9:30 a.m. Eastern Time, as described in the Company’s definitive proxy statement/prospectus, dated May 25, 2022 and filed with the SEC on such date (the “Proxy Statement”). The Warrant Holder Meeting will be held via live webcast at www.meetnow.global/MYVPLYT on June 22, 2022, at 10:00 a.m. Eastern Time, as described in Company’s definitive proxy statement/prospectus, dated May 25, 2022 and filed with the SEC on such date .

Following the consummation of the business combination, Polestar’s common stock is expected to begin trading on Nasdaq on June 24, 2022 under the new ticker symbol “PSNY.”

Ends.

About Polestar

Polestar was established as a new, standalone Swedish premium electric vehicle manufacturer in 2017. Founded by Volvo Car AB (publ) (together with its subsidiaries, “Volvo Cars”) and Zhejiang Geely Holding Group Co., Ltd (“Geely”), Polestar enjoys specific technological and engineering synergies with Volvo Cars and benefits from significant economies of scale as a result.

Polestar is headquartered in Gothenburg, Sweden, and its vehicles are currently available and on the road in markets across Europe, North America, China and Asia Pacific. By 2023, the company plans that its cars will be available in an aggregate of 30 markets. Polestar cars are currently manufactured in two facilities in China, with additional future manufacturing planned in the USA.

In September 2021, Polestar announced its intention to list as a public company on the Nasdaq in a business combination agreement with Gores Guggenheim, Inc. Full information on this definitive agreement can be found here.

Polestar has produced two electric performance cars. The Polestar 1 was built between 2019 and 2021 as a low-volume electric performance hybrid GT with a carbon fibre body, 609 hp, 1,000 Nm and an electric-only range of 124 km (WLTP) – the longest of any premium hybrid car in the world.

The Polestar 2 electric performance fastback is the company’s first fully electric, high volume car. The Polestar 2 model range includes three variants with a combination of long- and standard range batteries as large as 78 kWh, and dual- and single-motor powertrains with as much as 300 kW / 408 hp and 660 Nm.

From 2022, Polestar plans to launch one new electric vehicle per year, starting with Polestar 3, the company’s first electric performance SUV which is expected to debut in October 2022. Polestar 4 is expected to follow in 2023, a smaller electric performance SUV coupe.

In 2024, the Polestar 5 electric performance 4-door GT is planned to be launched as the production evolution of Polestar Precept – the manifesto concept car that Polestar released in 2020 that showcases the brand’s future vision in terms of design, technology, and sustainability. As the company seeks to reduce its climate impact with every new model, Polestar aims to produce a truly climate-neutral car by 2030.

In early March 2022, Polestar revealed its second concept car, an electric performance roadster, which builds on the design, technology and sustainability ambitions laid out by Precept and showcases the brand’s vision for future sports cars. The hard-top convertible presents an evolution of the unique design language first shown by Precept and emphasizes a dynamic driving experience. The concept further develops the focus on sustainability and technology, aiming towards greater circularity.
