Forward-looking statements generally relate to future events or the future financial or operating performance of Polestar. For example, future product offerings or partnership, the refreshed strategic plan, financial or operating metrics and statements regarding future needs for funding are forward-looking statements.

These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by Polestar and its management, as the case may be, are inherently uncertain.

governmental incentives and fuel and energy prices; (11) the outcome of any legal proceedings that may be instituted against Polestar or others, adverse results from litigation, governmental investigations or audits, or tax-related proceedings or audits; (12) the ability to meet stock exchange listing standards; (13) changes in applicable laws or regulations or governmental incentive programs; (14) Polestar’s ability to establish its brand and capture additional market share, (15) the risks associated with negative press or reputational harm, including from lithium-ion battery cells catching fire or venting smoke; (65) delays in the design, development, manufacture, launch and financing of Polestar’s vehicles and other product offerings, and Polestar’s reliance on a limited number of vehicle models to generate revenues; (16) Polestar’s ability to continuously and rapidly innovate, develop and market new products; (17) risks related to future market adoption of Polestar’s offerings; (18) risks related to Polestar’s distribution model; (19) the impact of the global COVID-19 pandemic, inflation, interest rate changes, the ongoing conflict between Ukraine and Russia and in Israel and the Gaza Strip, supply chain disruptions, fuel and energy prices and logistical constraints on Polestar, Polestar’s projected results of operations, financial performance or other financial and operational metrics, or on any of the foregoing risks; (20) Polestar’s ability to forecast demand for its vehicles; (21) Polestar’s ability to raise additional funding; (22) Polestar’s ability to successfully execute cost-cutting activities and strategic efficiency initiatives; (and (23) other risks and uncertainties set forth in the sections entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in Polestar’s Form 20-F, and other documents filed, or to be filed, with the SEC by Polestar.
