NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
2.1 Basis of preparation
The Unaudited Interim Condensed Consolidated Financial Statements (the "Interim Financial Statements") have been prepared in accordance with IAS 34 - Interim Financial Reporting. Accordingly, they do not include all the information and disclosures required in consolidated financial statements and should be read in conjunction with the Group’s Consolidated Financial Statements for the year ended December 31, 2020.
In accordance with IAS 1- Presentation of Financial Statements, the Interim Financial Statements are prepared on the assumption that Constellium is a going concern and will continue in operation for the foreseeable future.
The accounting policies adopted in the preparation of the Interim Financial Statements are consistent with those followed in the preparation of the Group’s Consolidated Financial Statements for the year ended December 31, 2020, except for the application of the effective tax rate method in accordance with IAS 34 - Interim Financial Reporting.
The Interim Financial Statements are presented in millions of Euros, except Earnings per share in Euros. Certain reclassifications may have been made to prior year amounts to conform to the current year presentation.
The Interim Financial Statements were authorized for issue by management on July 26, 2021.
2.2 New and amended standards and interpretations
Several amendments apply for the first time in 2021, but have no impact on the Interim Financial Statements of the Group.
The Group has not early adopted any other standard, interpretation or amendment that has been issued but is not yet effective. The Group plans to adopt the new standards and interpretations on their required effective dates.
2.3 Judgments in applying accounting policies and key sources of estimation uncertainty
The preparation of financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent liabilities. These judgments, estimates and assumptions are based on management’s best knowledge of the relevant facts and circumstances, giving consideration to previous experience. However, actual results may differ from the amounts included in the financial statements.
In preparing these Interim Financial Statements, the significant judgments made by management in applying the Group’s accounting policies and the key sources of estimation uncertainty were the same as those applied to the Consolidated Financial Statements at and for the year ended December 31, 2020, as well as the application of the effective tax rate method for the determination of the income tax provision.

(A)Metal price lag represents the financial impact of the timing difference between when aluminium prices included within Constellium's Revenue are established and when aluminium purchase prices included in Cost of sales are established. The Group accounts for inventory using a weighted average price basis and this adjustment aims to remove the effect of volatility in LME prices. The calculation of the Group metal price lag adjustment is based on an internal standardized methodology calculated at each of Constellium’s manufacturing sites and is primarily calculated as the average value of product recorded in inventory, which approximates the spot price in the market, less the average value transferred out of inventory, which is the weighted average of the metal element of cost of sales, based on the quantity sold in the period.

As a result, the fair value of the related derivatives accumulated in equity was reclassified in the Interim Income Statement and resulted in a €5 million loss.
(C)In June 2020, the main customer of the Nanjing Automotive Structures plant (China) announced a suspension of its operations and a strategic reorganization. As a result, we tested the asset for impairment and recorded an impairment charge of €5 million for the six months ended June 30, 2020.

10.4 Factoring arrangements
The Group factors trade receivables under committed factoring agreements in the United States, France, Germany, Switzerland and the Czech Republic:
•In the United States, Constellium Muscle Shoals LLC is party to a factoring agreement with a maximum capacity of $300 million and a maturity date in September 2021 and Constellium Automotive USA LLC is party to a factoring agreement with a maximum capacity of $25 million and a maturity date in December 2021.
•The factoring agreement in place for our entities in France has a maximum capacity of €255 million (including a €20 million recourse line) and a maturity date in December 2023.
•Factoring agreements in place for our entities in Germany, Switzerland and the Czech Republic have a combined maximum capacity of €150 million and maturity dates in December 2023.
In addition, the Group sells receivables from one of its German customers under an uncommitted factoring facility whereby receivables sold are confirmed by the customer.
These factoring agreements contain certain customary affirmative and negative covenants, including some relating to the administration and collection of the assigned receivables, the terms of the invoices and the exchange of information, but do not contain maintenance financial covenants. In addition, the commitment of the factor to buy receivables under the Muscle Shoals factoring agreement is subject to certain credit ratings being maintained. The Group was in compliance with all applicable covenants at and for the six months ended June 30, 2021 and 2020.
Under the Group’s factoring agreements, most of the trade receivables are sold without recourse. Where the Group has transferred substantially all the risks and rewards of ownership of the receivables, the receivables are derecognized. Some
F-13

remaining receivables do not qualify for derecognition, as the Group retains substantially all the associated risks and rewards. At June 30, 2021, the total carrying amount of the original assets factored was €587 million, of which €384 million had been derecognized. At December 31, 2020, the total carrying amount of the original assets factored was €514 million, of which €398 million had been derecognized.
Amounts due to the factors in respect of trade receivables sold were €1 million and nil at June 30, 2021 and December 31, 2020, respectively.

16.3 Valuation hierarchy
The following table provides an analysis of financial instruments measured at fair value, grouped into levels based on the degree to which the fair value is observable:
•Level 1 is based on a quoted price (unadjusted) in active markets for identical financial instruments. Level 1 includes aluminium, copper and zinc futures that are traded on the LME.
•Level 2 is based on inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities, either directly (i.e. prices) or indirectly (i.e. derived from prices). Level 2 includes foreign exchange derivatives. The present value of future cash flows based on the forward or on the spot exchange rates at the balance sheet date is used to value foreign exchange derivatives.
•Level 3 is based on inputs for the asset or liability that are not based on observable market data (unobservable inputs). Trade receivables are classified as a Level 3 measurement under the fair value hierarchy.

|  | At June 30, 2021 |  | At December 31, 2020
(in millions of Euros) |  | Level 1 |  | Level 2 |  | Level 3 |  | Total |  | Level 1 |  | Level 2 |  | Level 3 |  | Total

There was no material transfer of asset and liability categories into or out of Level 1, Level 2 or Level 3 during the six months ended June 30, 2021 or the year ended 2020.
NOTE 17 - FINANCIAL RISK MANAGEMENT
The Group’s financial risk management strategy focuses on minimizing the cash flow impacts of volatility in foreign currency exchange rates and metal prices, while maintaining the financial flexibility the Group requires in order to successfully execute the Group’s business strategy.
Due to Constellium’s capital structure and the nature of its operations, the Group is exposed to the following financial risks: (i) market risk including foreign exchange, commodity price and interest rate risks; (ii) credit risk and (iii) liquidity and capital management risk.
The Group's financial institution counterparties may require margin calls should the mark-to-market of our derivatives hedging foreign exchange and commodity price risks exceed a pre-agreed contractual limit. With a view to avoiding possible margin
F-20

calls for significant market movements, the Group enters into derivatives with a large number of financial counterparties and monitors margin requirements on a daily basis. In addition, the Group (i) ensures that financial counterparts hedging transactional exposure are also hedging foreign currency loan and deposit exposures and (ii) holds a significant liquidity buffer in cash or in availability under its various borrowing facilities
17.1 Market risk
i. Commercial transaction exposures
The Group has agreed to supply a major customer with fabricated metal products from a Euro functional currency entity and to invoice in U.S. Dollars. The Group entered into significant foreign exchange derivatives that matched related highly probable future conversion sales. The Group designates these derivatives for hedge accounting, with a total nominal amount of $305 million and $330 million at June 30, 2021 and December 31, 2020 respectively, with maturities ranging from 2021 to 2024.
The table below details the effect of foreign currency derivatives in the Interim Income Statement and the Interim Statement of Comprehensive Income / (Loss):

Losses reclassified from OCI as a result of hedge accounting discontinuation (C) |  | 6 |  | — |  | (5) |  | — |  | (5)

(A)Gains or losses on the hedging instruments are expected to offset losses or gains on the underlying hedged forecasted sales that will be reflected in the future when these sales are recognized.
(B)Derivatives that qualify for hedge accounting are included in Revenue when the related customer invoices have been issued.
(C)In the six months ended June 30, 2020, we determined that a portion of the hedged forecasted sales for the second half of 2020 and for 2021, to which hedge accounting was applied, was no longer expected to occur. As a result, the fair value of the related derivatives accumulated in equity was reclassified in the Interim Income Statement and resulted a €5 million loss.
ii. Foreign exchange margin calls
There were no margin calls at June 30, 2021.The margin requirement related to foreign exchange hedges amounted to €3 million paid as collateral to counterparties at December 31, 2020.
F-21

iii. Commodities
The Group does not apply hedge accounting on commodity derivatives and therefore any mark-to-market movements are recognized in Other gains and losses – net.
17.2 Liquidity and capital risk management
The liquidity requirements of the overall Company are funded out of the Company's cash or by drawing on available credit facilities. The internal management of liquidity is optimized by means of cash pooling agreements and/or intercompany loans and deposits between the Company’s operating entities and central Treasury.
At June 30, 2021, the borrowing bases for the Pan-U.S. ABL, the French Inventory Facility, and the German Facilities were €337 million, €82 million, and €50 million, respectively. After deduction of amounts drawn and letters of credit, the Group had €461 million outstanding availability under these revolving credit facilities.
At June 30, 2021, liquidity was €887 million, comprised of €290 million of cash and cash equivalents and €597 million of available undrawn facilities, including the €461 million described above.

18.5 Ravenswood OPEB dispute
In 2018, the Group announced a plan to transfer certain participants in the Constellium Rolled Products Ravenswood Retiree Medical and Life Insurance Plan (“the Plan”) from a company-sponsored program to a third-party health network that provides similar benefits at a lower cost. This change in benefits resulted in the recognition of a gain of €36 million from negative past service cost, which was reduced by €3 million in 2019, €2 million in 2020 and €2 million in the second quarter of 2021 to reflect delays in the estimated implementation timetable. The United Steelworkers Local Union 5668 (the “Union”) is contesting the OPEB amendments and filed a lawsuit against Constellium Rolled Products Ravenswood, LLC ("Ravenswood") in a federal district court in West Virginia (the “District Court”) seeking to enjoin the Plan changes and to compel arbitration. The District Court issued an order in December 2018, enjoining Ravenswood from implementing the OPEB amendments pending resolution in arbitration. In September 2019, the arbitrator issued a decision ruling against Ravenswood and sustaining the Union’s grievance. Ravenswood filed a motion in the District Court to vacate this decision, which was denied in June 2020. In July 2020, Ravenswood appealed that denial to the Fourth Circuit Court of Appeals and that court decision is still pending. The Group intends to continue to vigorously defend this matter as it believes it has a strong legal position and it is probable that Ravenswood will ultimately prevail and be able to implement the OPEB amendments.

Contingencies
The Group is involved, and may become involved, in various lawsuits, claims and proceedings relating to customer claims, product liability, employee and retiree benefit matters and other commercial matters. The Group records provisions for pending litigation matters when it determines that it is probable that an outflow of resources will be required to settle the obligation, and such amounts can be reasonably estimated. In some proceedings, the issues raised are or can be highly complex and subject to significant uncertainties and amounts claimed are and can be substantial. As a result, the probability of loss and an estimation of damages are and can be difficult to ascertain. In exceptional cases, when the Group considers that disclosures relating to provisions and contingencies may prejudice its position, disclosures are limited to the general nature of the dispute.

NOTE 22 - SHARE-BASED COMPENSATION
Description of plans
Performance-Based Restricted Stock Units (equity-settled)
In May 2021, the Company granted Performance Stock Units (PSUs) to selected employees. These units vest after three years from the grant date if the following conditions are met:
•A vesting condition under which the beneficiaries must be continuously employed by the Company through the end of the vesting period; and
•A performance condition, contingent on the TSR performance of Constellium shares over the vesting period compared to the TSR of specified indices. PSUs will ultimately vest based on a vesting multiplier which ranges from 0% to 200%.
The following table lists the inputs to the valuation model used for the PSUs granted in May 2021:

|  | May 2021 PSUs |  |
Fair value at grant date (in euros) |  | 21.84 |  |
Share price at grant date (in euros) |  | 13.90 |  |
Dividend yield |  | — |  |
Expected volatility (A) |  | 71% |  |
Risk-free interest rate (US government bond yield) |  | 0.31% |  |
Model used |  | Monte Carlo |  |

(A)Volatility in the share prices of the Company and companies included in indices were estimated based on observed historical volatilities over a period equal to the PSU vesting period.
The PSUs granted in May 2018 were vested in May 2021 and achieved a TSR performance of 182.9%. 1,161,718 shares related to this vesting were delivered to beneficiaries.

Restricted Stock Units Award Agreements (equity-settled)
During the six months ended June 30, 2021, the Company granted Restricted Stock Units (RSUs) to a certain number of employees subject to the beneficiaries remaining continuously employed within the Group from the grant date through the end of the vesting period. The vesting period is three years. The fair value of the RSUs awarded is €13.9, being the quoted market price at grant date.
Expense recognized during the period
In accordance with IFRS 2, share-based compensation is recognized as an expense over the vesting period. The estimate of this expense is based upon the fair value of a potential ordinary share at the grant date. The total expense related to the potential ordinary shares for the six months ended June 30, 2021 and 2020 amounted to €7 million and €8 million, respectively.
