Forward-Looking Statements

Certain statements in this Current Report may be considered “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally relate to future events or the future financial or operating performance of the Company and Polestar Performance AB and its affiliates (“Polestar”). For example, projections of future revenue, volumes and other metrics are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “may”, “should”, “expect”, “intend”, “will”, “estimate”, “anticipate”, “believe”, “predict”, “potential”, “forecast”, “plan”, “seek”, “future”, “propose” or “continue”, or the negatives of these terms or variations of them or similar terminology. Such forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward looking statements.

These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by the Company and its management, and Polestar and its management, as the case may be, are inherently uncertain. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: (a) the occurrence of any event, change or other circumstances that could give rise to the termination of definitive agreements with respect to proposed Business Combination; (b) the outcome of any legal proceedings that may be instituted against the Company, the combined company or others following the announcement of the Business Combination and any definitive agreements with respect thereto; (c) the inability to complete the Business Combination due to the failure to obtain approval of the stockholders of the Company, to obtain financing to complete the Business Combination or to satisfy other conditions to Closing; (d) changes to the proposed structure of the Business Combination that may be required or appropriate as a result of applicable laws or

regulations or as a condition to obtaining regulatory approval of the Business Combination; (e) the ability to meet stock exchange listing standards following the consummation of the Business Combination; (f) the risk that the Business Combination disrupts current plans and operations of Polestar as a result of the announcement and consummation of the Business Combination; (g) the ability to recognize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (h) costs related to the Business Combination; (i) risks associated with changes in applicable laws or regulations and Polestar’s international operations; (j) the possibility that Polestar or the combined company may be adversely affected by other economic, business, and/or competitive factors; (k) Polestar’s estimates of expenses and profitability; (l) Polestar’s ability to maintain agreements or partnerships with its strategic partners Volvo Cars and Zhejiang Geely Holding Group Co., Ltd and to develop new agreements or partnerships; (m) Polestar’s ability to maintain relationships with its existing suppliers and strategic partners, and source new suppliers for its critical components, and to complete building out its supply chain, while effectively managing the risks due to such relationships; (n) Polestar’s reliance on its partnerships with vehicle charging networks to provide charging solutions for its vehicles and its strategic partners for servicing its vehicles and their integrated software; (o) Polestar’s ability to establish its brand and capture additional market share, and the risks associated with negative press or reputational harm, including from lithium-ion battery cells catching fire or venting smoke; (p) delays in the design, manufacture, launch and financing of Polestar’s vehicles and Polestar’s reliance on a limited number of vehicle models to generate revenues; (q) Polestar’s ability to continuously and rapidly innovate, develop and market new products; (r) risks related to future market adoption of Polestar’s offerings; (s) increases in costs, disruption of supply or shortage of materials, in particular for lithium-ion cells or semiconductors; (t) Polestar’s reliance on its partners to manufacture vehicles at a high volume, some of which have limited experience in producing electric vehicles, and on the allocation of sufficient production capacity to Polestar by its partners in order for Polestar to be able to increase its vehicle production capacities; (u) risks related to Polestar’s distribution model; (v) the effects of competition and the high barriers to entry in the automotive industry, and the pace and depth of electric vehicle adoption generally on Polestar’s future business; (w) changes in regulatory requirements, governmental incentives and fuel and energy prices; (x) the impact of the global COVID-19 pandemic on the Company, Polestar, Polestar’s post business combination’s projected results of operations, financial performance or other financial metrics, or on any of the foregoing risks; and (y) other risks and uncertainties set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in the Company’s final prospectus relating to its initial public offering (File No. 333-253338) declared effective by the SEC on March 22, 2021, and other documents filed, or to be filed, with the SEC by the Company or ListCo, including the Registration/Proxy Statement and the Definitive Proxy Statement (each, as defined below). There may be additional risks that neither the Company, Polestar nor ListCo presently know or that the Company, Polestar or ListCo currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements.
