Polestar and Gores Guggenheim, Inc. Announce Closing of Business Combination

Polestar raises approximately $890 million gross proceeds; begins trading June 24 on Nasdaq under ticker “PSNY”

GOTHENBURG AND LOS ANGELES – 23 June 2022. Polestar Performance AB and its affiliates (“Polestar” or the “Company”), the global pure play, premium electric performance car company, and Gores Guggenheim, Inc. (“Gores Guggenheim”) (Nasdaq: GGPI, GGPIW and GGPIU), a special purpose acquisition company (“SPAC”) formed by affiliates of The Gores Group and Guggenheim Capital, LLC, announced today the completion of their previously announced business combination (the “Business Combination”). The combined company will retain the Polestar name and will commence trading on the Nasdaq under the new ticker symbol “PSNY” on June 24, 2022. The Business Combination was approved at a special meeting of Gores Guggenheim, Inc. stockholders on June 22, 2022.

Polestar represents a unique combination of start-up agility, backed by nearly 100 years of manufacturing experience and industrial infrastructure. The listing on the Nasdaq will help Polestar achieve its plans for rapid growth, anchored by its key values of design, innovation and sustainability. With two award-winning cars on the road in 25 markets, Polestar plans to increase sales volumes tenfold from approximately 29,000 cars in 2021 to 290,000 in 2025.

Thomas Ingenlath, Chief Executive Officer of Polestar, says: “Listing on the Nasdaq is an incredibly proud moment for Polestar. We set out to create an outstanding new EV brand with the mission to accelerate the shift towards sustainable mobility. With 55,000 cars on the road today and global recognition as made evident by over 100 awards, we have built a strong foundation for future growth. We are now expanding our product range with three new premium electric models, including two SUVs, by 2024. The first, Polestar 3, a full-size electric SUV, will launch in October 2022 and sets a new standard in this high margin, premium segment.

“Gores Guggenheim has been an excellent partner during this process and I send a big thank you to Alec Gores and his great team. This milestone will help accelerate Polestar’s growth plans and help us drive our industry-leading sustainability goals forward.”

Alec Gores, Chairman and Chief Executive Officer of The Gores Group, states: “It’s been a pleasure partnering with Thomas and the Polestar team – alongside Volvo Cars and Geely Holding – as they continue to disrupt the EV space and reach their sustainability goals and we look forward to what’s ahead. Polestar has proven itself to be a true leader and innovator with premier vehicles, industry-leading sustainability solutions, impressive sales and orders, and stunning designs for future models. This is a tremendous moment – especially in this market – and we are excited to continue to support Polestar through this next phase of growth.”

Polestar will be ringing the opening bell at Nasdaq in New York City on June 28, 2022 to celebrate the company’s public listing. A live stream of the event can be viewed by visiting https://livestream.com/accounts/27896496/events/10423292.

About Polestar

Polestar Automotive Holding UK PLC (Nasdaq: PSNY) (“Polestar”) is a Swedish premium electric vehicle manufacturer. Founded by Volvo Car AB (publ.) (together with its subsidiaries, “Volvo Cars”) and Zhejiang Geely Holding Group Co., Ltd (“Geely”), in 2017, 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.

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 hybrid car in the world at the time.

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 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 emphasises a dynamic driving experience. The concept further develops the focus on sustainability and technology, aiming towards greater circularity.
