EBITDA 6 totaled €771 million in 2021 (10.7% of consolidated revenue 4 ) versus €648 million (9.2% of consolidated revenue 4 ) in 2020. The Industries business line posted an EBITDA 6 rate of 12.9% compared to 11% in 2020. In the second half of the year, EBITDA 6 amounted to €310 million (9.0% of revenue) as opposed to €477 million in the second half of 2020 (11.6% of revenue) and €461 million in the first half of 2021 (12.2% of revenue). In 2021, operating margin totaled €303 million and represented 4.2% of consolidated revenue 4 , of which €271 million for Plastic Omnium Industries (5.2% of revenue) and €32 million for Plastic Omnium Modules (1.6% of revenue), an assembly activity whose performance should be assessed in relation to its low capital intensity. NET RESULT - GROUP SHARE: €126 MILLION The Group recorded €56 million in non-recurring expenses in 2021 compared to €334 million in 2020. The sharp reduction between 2020 and 2021 is due to the absence in 2021 of significant assets write-downs, unlike in 2020, when the drop in volumes due to the pandemic and the assumption of a slow recovery scenario in worldwide automotive production led the Group to adjust the value of the assets concerned. Net financial expenses amounted to -€51 million in 2021 (0.7% of revenue) compared to -€69 million in 2020 as a result of a lower average cost of debt. Tax expenses amounted to -€60 million compared to a tax income of €31 million in 2020 related to the effects of deferred taxes. Net result group share amounted to €126 million in 2021 compared to a loss of €251 million in 2020, related to a write-down of assets of €255 million. In the 2 nd half of 2021, in a context of deteriorating market conditions, net result group share amounted to -€16 million, a loss limited by the flexibility and cost optimization initiatives.

ECONOMIC REVENUE 1 €8,017 MILLION, UP 4.6% AT CONSTANT SCOPE AND EXCHANGE RATES 2 In 2021, the semiconductor shortage reduced worldwide automotive production by 9.6 million vehicles compared to forecasts at the beginning of the year. This amounted to 74.1 million vehicles compared to 71.5 million in 2020, the year in which the pandemic emerged. In this context, Plastic Omnium’s business activities fared significantly better than automotive production in Europe (outperformance of 5.3 points), North America (outperformance of 2.9 points), China (outperformance of 4.1 points) and Asia excluding China (outperformance of 10.3 points). The Group's economic revenue 1 (with share of revenue from joint ventures, particularly in China), amounted to €8,017 million, up 3.7%, and 4.6% at constant scope and exchange rates 2 compared to 2020. Plastic Omnium's consolidated revenue 4 amounted to €7,233 million in 2021, up 3.3% at constant scope and exchange rates 2 . RESILIENT FINANCIAL PERFORMANCE The volatility of the markets in 2021, and the weak rebound, as a result of the global shortage of semiconductors, led Plastic Omnium to production spikes (stop&go) and plant closures over several weeks. At the same time, the Group recorded increases in the prices of raw materials and transportation in several countries. The impact of these exogenous factors is estimated at €160 million, with production stoppages representing the majority of these costs. In addition to flexibility improvement measures, the OMEGA transformation plan, initiated in 2020, enabled the Group to limit the financial impact of production losses, notably through the two key initiatives, indirect purchasing and design and development. The plan contributed to €100 million in annual run-rate savings in 2021.

PLASTIC OMNIUM Notice of meeting 2022

BRIEF PRESENTATION

However, Plastic Omnium remains vigilant as to the indirect impacts that this conflict could have, in particular on energy prices and consumer confidence, as well as on supply difficulties for raw materials and components that some of its customers may encounter. 2022 OUTLOOK Plastic Omnium has set its targets for 2022 on the basis of the worldwide automotive production announced by IHS on 11 February 2022, at 81 million vehicles (passenger vehicles < 3.5 T + light commercial vehicles), with a discount of 5%*. This prudence is based on the short-term market challenges (reduced visibility, inflation and tension in the labor market) to which the Group intends to respond through its agility. At the same time, in the longer term, the Group aims to play an active role in the transformation of the automotive industry. It will continue its industrial deployment in growth regions and its innovation efforts to maintain its leadership and increase content per vehicle. Plastic Omnium’s objectives for 2022 are: economic revenue 1 that outperforms growth in worldwide j automotive production; an operating margin 3 of between 5% and 6% of revenue; j free cash-flow 5 generation of more than €260 million. j * Supply disruptions – particularly of semiconductor components – are continuing to lead to reduced production at several car manufacturers and suppliers. Plastic Omnium, which is indirectly affected, is managing this situation as closely as possible. Any significant change affecting these forecasts will be reported. GLOSSARY Economic revenue reflects the Group’s operational and managerial 1. reality. It corresponds to consolidated revenue plus revenue from the Group’s joint ventures consolidated at their percentage of ownership: BPO (50%), YFPO (50%) for Plastic Omnium Industries and SHB Automotive modules (33%) for Plastic Omnium Modules. Like-for-like: at constant scope and exchange rates. 2. a) The currency effect is calculated by applying the exchange rate of the current period to the revenue of the previous period. In 2021, currency effects had a negative impact of €66 million on economic revenue and €73 million on consolidated revenue. b) The scope effect was not material in 2021. Operating margin includes the share of the results of companies 3. which have been consolidated using the equity method, and the amortization of intangible assets acquired, before other operating income and expenses. Consolidated revenue does not include the share of joint ventures, 4. which are accounted for by the equity method, pursuant to IFRS 10, 11 and 12. Free cash-flow corresponds to the operating cash-flow, less tangible 5. and intangible investments net of disposals, taxes and net interest paid +/- variation of the working capital requirements (cash surplus from operations). EBITDA corresponds to the operating margin plus the share of profit 6. of associates and joint ventures before depreciation/amortization and operating provisions. Net debt includes all long-term borrowings, short-term loans and 7. bank overdrafts less loans, marketable debt instruments and other non-current financial assets, and cash and cash equivalents.

FREE CASH-FLOW 5 OF €251 MILLION COMPARED TO €34 MILLION IN 2020 In a volatile market that lacks visibility in the second half of 2021, the Group has been particularly vigilant about its investments and the management of its working capital requirement. Over the year, Plastic Omnium's investments were limited to €294 million, i.e. 4.1% of consolidated revenue (compared to €374 million, i.e. 5.3% in 2020), i.e. a decrease of €80 million ( i.e. -21.4%). With an industrial capacity that can now ensure future growth, Plastic Omnium is prioritizing its investments in innovation, new generation radars, modules dedicated to electric vehicles and lastly, in hydrogen, one of the future growth drivers for the Group. At the same time, the working capital requirement amounted to -€498 million at the end of 2021, compared to -€539 million in 2020. This limited deterioration of €41 million is part of a crisis context where the “stop&go” phenomenon makes inventory management particularly complex. Thanks to these elements and to an operating cash-flow of €616 million (compared to €453 million in 2020), Plastic Omnium generated free cash-flow 5 of €251 million, i.e. 3.5% of consolidated revenue 4 compared to €34 million in 2020 (0.5%). After free cash-flow 5 of €151 million in the first half of the year, Plastic Omnium achieved free cash-flow 5 of €100 million in the second half. A SOLID FINANCIAL STRUCTURE TO SUPPORT GROWTH At 31 December 2021, net debt 7 amounted to €854 million, close to that of 31 December 2020 (€807 million) and down excluding investments in EKPO. During the year, Compagnie Plastic Omnium SE paid out dividends of €87 million on its 2020 results (dividend of €0.49 per share, stable compared to that for the 2019 fiscal year). In 2021, the Group’s net debt 7 represented 41% of shareholders' equity and 1.1 times EBITDA 6 , leaving Plastic Omnium with significant financial leeway to achieve future growth. At 31 December 2021, the Group had liquidities of €2.7 billion comprising €0.8 billion in available cash and €1.9 billion in confirmed, undrawn credit lines, with an average maturity of 3.9 years and without any covenants. Proposed dividend per share of €0.28, i.e. a pay-out of 32% The Board of Directors will propose a dividend of €0.28 per share to the General Meeting of Shareholders of 21 April 2022. The dividend will be paid on 2 May 2022, after approval by the General Meeting of Shareholders. OUTLOOK AND EVENTS AFTER THE REPORTING PERIOD No event likely to have a material impact on the Group’s business, financial position, earnings or assets and liabilities at 31 December 2021 has occurred since the closing date. The Russian invasion of Ukraine from 24 February 2022 and the international sanctions imposed on Russia are not expected to have any significant direct impacts on the Group’s activities and assets for the following reasons: Plastic Omnium has no production or customers in Ukraine; j The activities and assets of its Russian plants are not significant at j Group level (revenue < 0.6% of the Group’s economic revenue in 2021).
