 **Notes to the Unaudited Interim Condensed Consolidated Financial Statements**

 **NOTE 1 - BUSINESS AND SUMMARY OF ACCOUNTING POLICIES** 

Constellium is a global leader in the design and manufacture of a broad range of innovative specialty rolled and extruded aluminum products, serving a wide range of blue-chip customers primarily in the aerospace, packaging, automotive, commercial transportation, general industrial and defense end-markets. At June 30, 2025, the Group operated 25 manufacturing facilities, 3 R&D centers and 3 administrative centers.

Constellium SE, a French *Societas Europaea* (SE), is the parent company of the Group.

Unless the context indicates otherwise, when we refer to "we", "our", "us", "Constellium", the "Group" and the "Company" in this document, we are referring to Constellium SE and its subsidiaries.

**Basis of presentation and principles of consolidation**

The accompanying unaudited interim condensed consolidated financial statements include the accounts of Constellium SE and its controlled subsidiaries. All intercompany transactions and balances are eliminated.

The accompanying unaudited interim condensed consolidated financial statements have been prepared by Constellium in accordance with U.S. generally accepted accounting principles ("GAAP") and the rules and regulations of the Securities and Exchange Commission ("SEC") applicable for interim periods and, therefore, do not include all information and footnotes required by GAAP for complete financial statements. In management's opinion, all adjustments (which include normal recurring adjustments) considered necessary for a fair statement of its financial position at June 30, 2025, results of operations and cash flows for the three-month and six-month periods ended June 30, 2025 and 2024 have been included. The accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the Group's audited consolidated financial statements and accompanying notes in its annual report on Form 10-K for the year ended December 31, 2024. The results of operations for our interim periods are not necessarily indicative of the results of operations that may be achieved for the entire 2025 fiscal year.

**Use of estimates and assumptions**

The preparation of the Group's consolidated financial statements in accordance with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent liabilities. The principal areas of judgment relate to (1) impairment of assets; (2) actuarial assumptions related to pension and other postretirement benefit plans; (3) tax uncertainties and valuation allowances; and (4) assessment of loss contingencies, including environmental and litigation liabilities. These judgments, estimates and assumptions are based on management's best knowledge of the relevant facts and circumstances, giving consideration to previous experience. Future events and their effects cannot be predicted with certainty, and accordingly, our accounting estimates require the exercise of judgment. The accounting estimates used in the preparation of our consolidated financial statements may change as new events occur, more experience is acquired, additional information is obtained, and our operating environment changes. The Group continuously reviews its significant assumptions and estimates in light of the uncertainty associated with the global geopolitical and macroeconomic conditions and their potential direct and indirect impacts on its business and its financial statements. There can be no guarantee that our assumptions will materialize or that actual results will not differ materially from estimates.

**Recently adopted and recently issued accounting guidance**

In December 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-09 - *Improvements to Income Tax Disclosures*. The standard requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions and applies to all entities subject to income taxes. The new standard is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. This accounting standard is effective for annual disclosures in fiscal year ended December 31, 2025. We are currently evaluating the impact of adoption on our annual financial disclosures.

In November 2024, the FASB issued ASU 2024-03 - *Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures*, requiring public business entities to disclose, on an annual and interim basis, disaggregated information about certain income statement line items in a tabular format in the notes to the financial statements. The standard

------

is intended to benefit investors by providing more detailed expense information notably on employee compensation, depreciation and amortization and purchase of inventory, which is critical to understanding an entity's performance, assessing its prospects for future cash flows and comparing its performance both over time and with that of other entities. This accounting standard as updated in ASU 2025-01 - *Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date* which clarified the interim reporting effective date of ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted and the guidance may be applied prospectively or retrospectively. We are currently evaluating the impact of adoption on our financial disclosures.

The Group plans to adopt these new standards, amendments and interpretations on their required effective dates and does not expect any material impact on its financial position, results of operations and cash flows as a result of their adoption.

**NOTE 2 - REVENUE**

In the following table, revenue is disaggregated by product line. See Note 3 - Segment information herein for additional disclosures of revenue disaggregated by operating segments.

(A)Metal price lag represents the financial impact of the timing difference between when aluminum prices included within Constellium's Revenue are established and when aluminum purchase prices included in Cost of sales are established, which is a non-cash financial impact. The metal price lag will generally increase our earnings in times of rising primary aluminum prices and decrease our earnings in times of declining primary aluminum prices. The calculation of metal price lag adjustment is based on a standardized methodology applied at each of Constellium's manufacturing sites. Metal price lag is calculated as the average value of product purchased in the period, approximated at the market price, less the value of product in inventory at the weighted average of metal purchased over time, multiplied by the quantity sold in the period.

(B)For the three and six months ended June 30, 2024, impairment related to property, plant and equipment in our Valais operations.

(C)For the three months ended June 30, 2025, other mainly includes 2 million of clean-up costs related to the flooding of our facilities in Valais (Switzerland). For the six months ended June 30, 2025, Other mainly includes $9 million of insurance proceeds and $7 million of clean-up costs related to the flooding of our facilities in Valais (Switzerland). For the three and six months ended June 30, 2024, other was related to $6 million of inventory impairment as a result of the flooding of our facilities in Valais (Switzerland) at the end of June 2024 as well as $2 million of costs associated with non-recurring corporate transformation projects.

(A)For the three months ended June 30, 2025, and 2024, interest expense on borrowings included $22 million and $21 million of interest expenses related to Constellium SE Senior Notes including amortization of debt issuance costs, respectively. For the six months ended June 30, 2025, and 2024, interest expense on borrowings included $44 million and $43 million of interest expenses related to Constellium SE Senior Notes including amortization of debt issuance costs, respectively.

(B) &nbsp;&nbsp;&nbsp;&nbsp;The Group hedges the currency exposure when using external funding sources in a currency different from the functional currency of the entities being funded. Changes in the fair value of these hedging derivatives are recognized within Finance costs – net in the Interim Consolidated Income Statement.

(C) &nbsp;&nbsp;&nbsp;&nbsp;Borrowing costs directly attributable to the construction of assets are capitalized. The capitalization rate was 5% for the three and six months ended June 30, 2025, and 2024.

**NOTE 6 - INCOME TAX** 

Income tax expense for interim periods is recognized based on the annualized effective tax rate expected for the full year adjusted for the tax effect of certain items recognized in full in the interim period.

Our effective tax rate was 35.7% and 26.0% of our income before income tax for the three months ended June 30, 2025 and 2024, respectively, and 37.6% and 26.0% of our income before income tax for the six months ended June 30, 2025, and 2024, respectively.

The effective tax rate for the three and six months ended June 30, 2025 includes the impact of the temporary surtax in France, which was enacted in February 2025 and resulted in a statutory tax rate of 29.28% for 2025, compared to 25.82% in 2024. The difference between the effective tax rate and the statutory tax rate for the three and six months ended June 30, 2025 was primarily due to the geographical mix of our pre-tax results and losses in certain jurisdictions where we have recorded a full valuation allowance.

**NOTE 7 - EARNINGS PER SHARE**

Basic earnings per share are computed using the weighted-average number of ordinary shares outstanding during the period. Diluted earnings per share are computed using the weighted-average number of ordinary shares and ordinary share equivalents outstanding during the period. Ordinary share equivalents represent the dilutive effect of outstanding equity-based awards.

The reconciliation of the numerator and denominator of basic and diluted earnings per share was as follows:

---

For the three and six months ended June 30, 2025, and 2024, no ordinary shares assuming exercise of equity-based awards were excluded from the computation of diluted earnings per share because the effect of their exercise would be anti-dilutive.

**Factoring arrangements**

The Group has entered into several accounts receivable factoring programs with various financial institutions for certain receivables of the Group.

The proceeds from the sale of certain of these receivables comprise a combination of cash and a deferred purchase price receivable. The deferred purchase price receivable is ultimately realized by the Group following the collection by the financial institutions of the underlying receivables sold. The beginning deferred purchase price balance for six months ended June 30, 2025 and 2024 were $2 million and $8 million, respectively. During each of the aforementioned periods, there were non-cash additions to the deferred purchase price receivable of $0 million and $41 million (these additions are excluded from the Interim Statement of Cash Flow as they are non-cash investing transactions) and cash collections of $2 million and $40 million, respectively. This activity resulted in an ending deferred purchase price receivable balance of $0 million and $9 million, for the six months ended June 30, 2025 and 2024, respectively, recorded in Fair value of derivatives instruments and other financial assets in the consolidated balance sheets.

The Group has recorded $11 million and $10 million of expense related to its factoring programs in the six months ended June 30, 2025 and 2024, respectively, and has presented these amounts in Other gains and losses - net in its Interim Consolidated Income Statement.

The fair values of trade receivables, other financial assets and liabilities approximate their carrying values, as a result of their liquidity or short maturity and the fair value of borrowings are disclosed in Note 11 - Debt.

&nbsp;&nbsp;&nbsp;&nbsp;**12.2 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1 is based on a quoted price (unadjusted) in active markets for identical financial instruments. Level 1 includes aluminum, copper and zinc futures that are traded on the LME.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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, natural gas derivatives, silver derivatives and aluminum premium 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

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, 2025, nor the year ended December 31, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;**12.3 Foreign exchange** 

Foreign exchange risk is the risk that the fair value or future cash flows of an exposure will fluctuate because of changes in foreign exchange rates.

Net assets, earnings and cash flows are influenced by multiple currencies due to the geographic diversity of sales and the countries in which the Group operates.

Constellium has the following foreign exchange risk: i) transaction exposures, which include commercial transactions related to forecasted sales and purchases and on-balance sheet receivables/payables resulting from such transactions and financing transactions related to external and internal net debt, and ii) translation exposures, which relate to net investments in foreign entities that are converted in U.S. dollar amounts in the Consolidated Financial Statements.

Foreign exchange impacts related to the translation of net investments in non-USD functional currency subsidiaries from functional currency to U.S. dollar, and of the related revenue and expenses, are not hedged as the Group operates in these various countries on a permanent basis except as described below.

&nbsp;&nbsp;&nbsp;&nbsp;***i. Commercial transaction exposures***

The Group policy is to hedge committed and highly probable forecasted foreign currency operational transactions. The Group uses foreign exchange forwards and foreign exchange swaps for this purpose.

The following tables outline the nominal value (converted to millions of U.S. Dollars at the closing rate) of forward derivatives for Constellium's most significant foreign exchange exposures at June 30, 2025.

The Group has agreed to supply a major customer with fabricated metal products from an entity with Euro functional currency, while invoicing in U.S. Dollars. The Group has entered into significant foreign exchange derivatives that matched related highly probable future conversion sales. The Group designates a substantial portion of these derivatives for hedge accounting, with a total nominal amount of $345 million and $410 million at June 30, 2025 and December 31, 2024 respectively, with maturities ranging from 2025 to 2029. Changes in the fair value of cash flow hedges are reported by the

(B)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 future years when these sales are recognized.

(C)Changes in fair value of derivatives that qualify for hedge accounting are included in revenue when the related customer invoices are issued.

&nbsp;&nbsp;&nbsp;&nbsp;***ii. Financing transaction exposures***

When the Group enters into intercompany loans and deposits, the financing is generally provided in the functional currency of the subsidiary. The foreign currency exposure of the Group's external funding and liquid assets is systematically hedged either naturally through intercompany foreign currency loans and deposits or through foreign currency derivatives.

At June 30, 2025, the net hedged position related to long-term and short-term loans and deposits in U.S. dollar included a forward sale of $254 million versus the Euro using simple foreign exchange forward contracts.

&nbsp;&nbsp;&nbsp;&nbsp;**12.4 Commodities**

The Group is subject to the effects of market fluctuations in the price of aluminum, which is the Group's primary metal input and a significant component of its output. The Group is also exposed to variation in regional premiums and in the price of zinc, natural gas, silver and copper, and other alloying metals, to a lesser extent.

The Group policy is to minimize exposure to aluminum price volatility by passing through the aluminum price risk to customers and using derivatives where necessary. For most of its aluminum price exposure, sales and purchases of aluminum are converted to be on the same floating basis and then the same quantities are bought and sold at the same market price.

Temporary increases in inventory, to the extent material, are sold forward to the expected sales date to ensure the price paid for the metal will be redeemed when it is sold.

The Group also purchases copper, aluminum premium, silver and zinc derivatives to offset the commodity exposure where sales contracts have embedded fixed price agreements for these commodities.

In addition, the Group purchases natural gas fixed price derivatives to lock in energy costs where a fixed price purchase contract is not possible.

At June 30, 2025, the nominal amount of commodity derivatives is as follows:

---

| | | | |
|:---|:---|:---|:---|
| ***(in millions of U.S. dollar)*** | &nbsp;&nbsp;&nbsp;&nbsp;**Maturity Year** | &nbsp;&nbsp;&nbsp;&nbsp;**Less than 1 year** | &nbsp;&nbsp;&nbsp;&nbsp;**Over 1 year** |
| Metal | 2025-2027 | **297** | **115** |
| Natural gas | 2025-2028 | **6** | **28** |

---

The value of the contracts will fluctuate due to changes in market prices but our hedging strategy helps protect the Group's margin on future conversion and fabrication activities. At June 30, 2025, these contracts were directly entered into with external counterparties.

The Group does not apply hedge accounting on commodity derivatives and therefore mark-to-market movements are recognized in Other gains and losses - net.

---

***Close down, environmental and remediation costs***

Environmental remediation costs are accounted for based on the Group's best estimate of the costs of its environmental clean-up obligations. The Group also records provisions for close down and restoration efforts based on the net present value of estimated future costs of the dismantling and demolition of infrastructure and the removal of residual material of disturbed areas. These provisions are expected to be settled over the next 40 years depending on the nature of the disturbance and the technical remediation plans.

***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 can be highly complex and subject to significant uncertainties and amounts claimed can be substantial. As a result, the probability of loss and an estimation of damages 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 matter in hand.

**NOTE 17 - SHARE-BASED COMPENSATION** 

***Performance-Based Restricted Stock Units (equity-settled)***

During the six months ended June 30, 2025, the Company granted 1,154,859 PSUs to selected employees of the Group and to the Chief Executive Officer. The fair value of PSU awards with performance and service conditions is estimated using the value of Constellium SE's ordinary shares on the date of grant. The fair value of PSU awards with market conditions is estimated using a Monte Carlo simulation model on the date of grant.

These units vest if the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A vesting condition under which the beneficiaries must be continuously at the service of the Company through the end of a three-year vesting period; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 during the six months ended June 30, 2025:

---

| | |
|:---|:---|
| | &nbsp;&nbsp;&nbsp;&nbsp; **2025 PSUs** |
| Fair value at grant date (in dollars) | **17.88** |
| Share price at grant date (in dollars) | **11.90** |
| Dividend yield | **—** |
| Expected volatility (A) | **47%** |
| Risk-free interest rate (US government bond yield) | **3.93%** |

---

(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.

***Restricted Stock Units Award Agreements (equity-settled)***

During the six months ended June 30, 2025, the Company granted 1,026,520 RSUs to selected employees of the Group and the Chief Executive Officer subject to the beneficiaries remaining continuously employed by or at the service of the Group from the grant date to the end of the three-year vesting period. The fair value of the RSUs awarded is $11.90, being the quoted market price at grant date.

***Expense recognized during the period***

Total share-based compensation expense was $13 million and $13 million for the six months ended June 30, 2025 and 2024, respectively.

At June 30, 2025, unrecognized compensation expense related to the RSUs was $21 million, which will be recognized over the remaining weighted average vesting period of 2.2 years and unrecognized compensation expense related to the PSUs was $34 million, which will be recognized over the remaining weighted average vesting period of 2.2 years.

***Vested plan during the period***

Fair values of vested RSUs and PSUs amounted to $23 million for six months ended June 30, 2025. They are excluded from the Statement of Cash flows as non-cash financing activities.

**Overview** 

We are a global leader in the development, manufacture and sale of a broad range of highly engineered, value-added specialty rolled and extruded aluminum products to the aerospace, packaging, automotive, commercial transportation, general industrial and defense end-markets. At June 30, 2025, we operated 25 production facilities, 3 R&D centers and 3 administrative centers.

We serve a diverse set of customers across a broad range of end-markets with different product needs, specifications and requirements. Our business is organized into three operating segments:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our Aerospace & Transportation ("A&T") operating segment offers a wide range of technically advanced aluminum products including plate, sheet and extrusions to blue-chip customers in the global aerospace, space, commercial transportation, general industrial and defense sectors. Many of the products are mission critical, which benefit from our world-class R&D and manufacturing capabilities and unique solutions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our Packaging & Automotive Rolled Products ("P&ARP") operating segment includes the production and development of customized rolled aluminum sheet products. We supply the packaging market with canstock and closure stock for the beverage and food industry, as well as foilstock for the flexible packaging market. In addition, we supply the automotive market with technically advanced products such as Auto Body Sheet ("ABS"), heat exchanger materials and battery foil products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our Automotive Structures & Industry ("AS&I") operating segment produces (i) technologically advanced structural solutions for the automotive industry including crash management systems, body structures, side impact beams and battery enclosure components, (ii) soft and hard alloy extrusions for automotive, transportation, and general industrial applications, and (iii) large profiles for rail and general industrial applications. We complement our products with a comprehensive offering of downstream technology and services, which include pre-machining, surface treatment, R&D and technical support services.

**Management Review and Outlook**

Constellium delivered solid results in the second quarter despite continued demand weakness across most of our end markets outside of packaging. We repurchased 3.4 million shares for $35 million during the quarter. The tariff and international trade situation remains highly unpredictable and is creating uncertainty in many of our end markets, especially automotive. We are proactively managing the business to the current environment and what is under our control. We remain focused on executing on our strategy, driving operational performance, reducing costs, managing capital discipline, generating Free Cash Flow and increasing shareholder value.

------

**Key Factors Influencing Constellium's Financial Condition and Results from Operations**

***Economic Conditions and Markets***

We are directly impacted by the economic conditions that affect our customers and the markets in which they operate. General economic and market conditions, such as the level of disposable income, the level of inflation, the rate of economic growth, the rate of unemployment, the rapid development of technology, interest rates, exchange rates and currency devaluation or revaluation, influence consumer confidence and consumer purchasing power. These factors, in turn, influence the demand for our products in terms of total volumes and prices that can be charged. We attempt to respond to the variability of economic conditions through the terms of our contracts with our customers and cost control.

In addition, although a number of our end-markets are cyclical in nature, we believe that the diversity of our portfolio and the secular growth trends we are experiencing in many of our end-markets will help the Company weather these economic cycles. In our three principal end-markets of aerospace, packaging and automotive:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Aerospace demand has stabilized following the sharp recovery post-COVID as OEMs continue to face supply chain challenges. We continue to believe that the long-term trends of increased passenger air traffic and fleet replacements with newer and more fuel efficient aircraft, along with new military and space programs, will help support favorable long-term demand conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Historically, demand for aluminum can packaging has been fairly resilient during various economic cycles. We believe canstock has an attractive long-term growth outlook due to increased consumer preference for aluminum cans as a packaging material of choice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Automotive vehicle sales tend to fluctuate with the general economic cycle and in recent years have also been impacted by global supply chain disruptions, affordability, customer offerings and consumer preference. However, aluminum demand has increased in recent years, driven by the vehicle lightweighting trend to improve energy efficiency, reduce emissions and enhance vehicle safety, which has resulted in more aluminum usage for new car models. We expect the lightweighting trend to continue in the future.

On July 4, 2025, the One Big Beautiful Bill Act (the "OBBB Act") was enacted in the U.S. The OBBB Act contains numerous tax provisions that, among other things, permanently extends certain provisions of the Tax Cut and Jobs Act and other changes to existing U.S. federal tax law and regulatory rules. Certain provisions of the law have effective dates ranging from 2025 through 2027. The Company is assessing the impact of the OBBB Act's relevant provisions and currently does not anticipate a significant impact on its financial statements for the fiscal year 2025.

***Geopolitical and Economic Instability***

During the first six months ended June 30, 2025, the Company continued to monitor geopolitical and economic instability. During the second quarter, there was continued uncertainty related to tariffs, trade wars, and their short and long-term potential impacts on the Company. Global and regional economies continue to be impacted by armed conflicts, sanctions, and volatility. While it is difficult to predict the impact of these events, we continuously monitor them and will develop contingency plans and counter measures as necessary to address adverse effects or disruptions to our operations as they arise.

***Product Price and Margin***

Our products are typically priced based on three components: (i) the LME price, (ii) a regional premium and (iii) a conversion margin.

***Aluminum Prices***

The price we pay for primary aluminum includes the LME price and regional premiums such as the Midwest premium for metal purchased in the U.S. or the Rotterdam premium for metal purchased in Europe. Both the LME price and the regional premiums can be volatile. Our business model aims to pass through aluminum price exposure by pricing our products to include the cost of the metal purchased and hedging any remaining exposure to the extent possible to achieve aluminum price neutrality.

The average LME transaction price, Rotterdam premium and Midwest premium per ton of primary aluminum for the three and six months ended June 30, 2025 and 2024 are presented below.

***Volumes***

The profitability of our business is determined, in part, by the volume of tons processed and sold. Increased production volumes will generally result in lower per unit costs. Higher volumes sold will generally result in additional revenue and associated profitability.

***Personnel Costs***

Our operations are labor intensive. Personnel costs include the salaries, wages and benefits of our employees, as well as costs related to temporary labor. During our seasonal peaks and the summer months, we have historically increased our temporary workforce to compensate for increased volume of activity and vacation schedules. Personnel costs generally increase and decrease with the expansion or contraction in production levels. Personnel costs also generally increase in periods of higher inflation.

***Energy***

Our operations require substantial amounts of energy to run, primarily electricity and natural gas. The magnitude of energy costs depends on the energy supply and demand relationships in the regions we operate in.

***Currency***

We are a global company with operations in the United States, France, Germany, Switzerland, the Czech Republic, Slovakia, Spain, Mexico, Canada and China. As such, we are exposed to transaction and translation impacts.

Transaction impacts arise when our businesses transact in a currency other than their own functional currency. As a result, we are exposed to foreign exchange risk on payments and receipts in multiple currencies. Where we have multiple-year sales agreements in U.S. dollars by euro-functional currency entities, we have entered into derivative contracts to forward sell U.S. dollars to match these future sales. With the exception of certain derivative instruments entered into to hedge the foreign currency risk associated with the cash flows of certain highly probable forecasted sales, which we have designated for hedge accounting, hedge accounting is not applied to such ongoing commercial transactions and therefore the mark-to-market impact is recorded in Other Gains and Losses - net.

Translation impacts result from the translation at each period of the results of functional currency entities other than U.S. dollar into our reporting currency, the U.S. dollar.

Our revenue is discussed in more detail in the "Segment Results" section.

***Cost of Sales***

For the three months ended June 30, 2025, cost of sales increased 11% to $1,840 million from $1,652 million for the three months ended June 30, 2024. This increase in cost of sales was primarily driven by an 18% increase in raw materials and consumables as a result of higher metal prices and higher sales volumes.

For the six months ended June 30, 2025, cost of sales increased 8% to $3,556 million from $3,287 million for the six months ended June 30, 2024. This increase in cost of sales was primarily driven by a 14% increase in raw materials and consumables as a result of higher metal prices.

***Selling and Administrative Expenses***

For the three months ended June 30, 2025, selling and administrative expenses increased 17% to $88 million from $75 million for the three months ended June 30, 2024. The increase was primarily driven by an increase in labor costs, including costs associated with corporate transformation projects, partially offset by lower headcounts.

For the six months ended June 30, 2025, selling and administrative expenses increased 7% to $166 million from $155 million for the six months ended June 30, 2024.

---

Realized gains or losses relate to financial derivatives used by the Group to hedge underlying commercial and commodity transactions. Realized gains and losses on these derivatives are recognized in Other Gains and Losses - net and are offset by the commercial and commodity transactions accounted for in revenue and cost of sales.

Unrealized gains or losses relate to financial derivatives used by the Group to hedge forecasted commercial and commodity transactions for which hedge accounting is not applied. Unrealized gains or losses on these derivatives are

------

recognized in Other Gains and Losses - net and are intended to offset the change in the value of forecasted transactions which are not yet accounted for.

Changes in realized (losses) / gains on derivatives for the three and six months ended June 30, 2025 as compared to the three and six months ended June 30, 2024 primarily reflected the fluctuation in commodity and energy prices.

Changes in unrealized (losses) / gains on derivatives for the three and six months ended June 30, 2025 as compared to the three and six months ended June 30, 2024 primarily reflected the fluctuation in foreign exchange.

For the three and six months ended June 30, 2024, impairment related to property, plant and equipment in our Valais operations.

For the three months ended June 30, 2025, the $2 million loss resulting from the flood in Valais correspond to clean-up costs.

For the three and six months ended June 30, 2024, the $6 million loss resulting from the flood in Valais related to inventory impairment.

For the six months ended June 30, 2025, the $2 million gain resulting from the flood in Valais includes $9 million of insurance proceeds, partially offset by $7 million of clean-up costs.

***Finance Costs, net***

For the three months ended June 30, 2025, finance costs, net increased 16% to $29 million from $25 million for the three months ended June 30, 2024. This increase primarily reflected higher borrowings on the Pan-U.S. ABL in 2025 and higher cost of Senior Notes as a result of our August 2024 refinancing compared to the three months ended June 30, 2024.

For the six months ended June 30, 2025, finance costs, net increased 8% to $56 million from $52 million compared to the six months ended June 30, 2024. This increase primarily reflected higher borrowings on the Pan-U.S. ABL in 2025 and higher cost of Senior Notes as a result of our August 2024 refinancing compared to the six months ended June 30, 2024.

***Income Tax***

For the three months ended June 30, 2025 and 2024, income tax was an expense of $20 million and an expense of $27 million, respectively. For the six months ended June 30, 2025 and 2024, income tax was an expense of $44 million and an expense of $35 million, respectively.

Our effective tax rate was 35.7% and 26.0% of our income before income tax for the three months ended June 30, 2025 and 2024, respectively, and 37.6% and 26.0% of our income before income tax for the six months ended June 30, 2025 and 2024, respectively.

The effective tax rate for the three and six months ended June 30, 2025 includes the impact of the temporary surtax in France, which was enacted in February 2025 and resulted in a statutory tax rate of 29.28% for 2025, compared to 25.82% in 2024. The difference between our effective tax rate and the statutory tax rate for the three and six months ended June 30, 2025 and 2024, respectively was primarily due to the geographical mix of our pre-tax results and losses in certain jurisdictions where we have recorded a full valuation allowance.

***Segment Adjusted EBITDA***

In considering the financial performance of the business, we analyze the primary financial performance measure of Segment Adjusted EBITDA in all of our business segments. Our Chief Operating Decision Maker, as defined under *Accounting Standards Codification (ASC) Topic 280 - Segment reporting* measures the profitability and financial performance of our operating segments based on Segment Adjusted EBITDA.

Segment Adjusted EBITDA is defined as income from continuing operations before income taxes, results from joint ventures, net finance costs, other expenses and depreciation and amortization as adjusted to exclude restructuring costs, impairment charges, unrealized gains or losses on derivatives and on foreign exchange differences on transactions that do not qualify for hedge accounting, metal price lag (as defined hereafter), share-based compensation expense, non-operating gains / (losses) on pension and other post-employment benefits, factoring expenses, effects of certain purchase accounting adjustments, start-up and development costs or acquisition, integration and separation costs, certain incremental costs and other exceptional, unusual or generally non-recurring items.

(A)Metal price lag represents the financial impact of the timing difference between when aluminum prices included within Constellium's Revenue are established and when aluminum purchase prices included in Cost of sales are established, which is a non-cash financial impact. The metal price lag will generally increase our earnings in times of rising primary aluminum prices and decrease our earnings in times of declining primary aluminum prices. The calculation of metal price lag adjustment is based on a standardized methodology applied at each of Constellium's manufacturing sites. Metal price lag is calculated as the average value of product purchased in the period, approximated at the market price, less the value of product in inventory at the weighted average of metal purchased over time, multiplied by the quantity sold in the period.

(B)For the three and six months ended June 30, 2024, impairment related to property, plant and equipment in our Valais operations.

(C)For the three months ended June 30, 2025, other mainly includes $2 million of clean-up costs related to the flooding of our facilities in Valais (Switzerland). For the six months ended June 30, 2025, Other mainly includes $9 million of insurance proceeds and $7 million of clean-up costs related to the flooding of our facilities in Valais (Switzerland). For the three and six months ended June 30, 2024, other was related to $6 million of inventory impairment as a result of the flooding of our facilities in Valais (Switzerland) at the end of June 2024 as well as $2 million of costs associated with non-recurring corporate transformation projects.

*A&T*

For the three months ended June 30, 2025, Adjusted EBITDA in our A&T segment decreased 13% to $78 million from $90 million for the three months ended June 30, 2024, primarily as a result of lower volumes, partially offset by favorable price and mix, lower operating costs and favorable impact from foreign exchange translation.

Segment Adjusted EBITDA results for our Holdings and Corporate segment reflected costs of $12 million and $6 million, for the three months ended June 30, 2025 and 2024, respectively and costs of $23 million and $14 million for the six months ended June 30, 2025 and 2024, respectively. This increase mainly results from higher labor costs, including costs associated with corporate transformation projects, as well as an unfavorable impact from foreign exchange translation.

**Liquidity and Capital Resources** 

Our primary sources of cash flow have historically been cash flows from operating activities and funding or borrowings from external parties.

Based on our current and anticipated levels of operations, and the condition in our markets and industry, we believe that our cash flows from operations, cash on hand, new debt issuances or refinancing of existing debt facilities, and availability under our factoring and revolving credit facilities will enable us to meet our working capital, capital expenditures, debt service and other funding requirements for the short-term and long-term.

It is our policy to hedge all highly probable or committed foreign currency operating cash flows. As we have significant third party future receivables denominated in U.S. dollars, we generally enter into combinations of forward contracts with financial institutions, selling forward U.S. dollars against euros.

When we are unable to align the price and quantity of physical aluminum purchases with that of physical aluminum sales, it is also our policy to enter into derivative financial instruments to pass through the exposure to metal price fluctuations to financial institutions.

As the U.S. dollar appreciates against the euro or the LME price for aluminum falls, the derivative contracts related to transactional hedging entered into with financial institution counterparties will have a negative mark-to-market.

In addition, we borrow in a combination of the U.S. dollar and euro. When the external currency mix of our debt does not match the mix of our assets, we use foreign currency derivatives to balance the risk.

Our financial institution counterparties may require margin calls should our negative mark-to-market exceed a pre-agreed contractual limit. In order to protect the Group from the potential margin calls for significant market movements, we maintain additional cash or availability under our various borrowing facilities, we enter into derivatives with a large number of financial counterparties and we monitor potential margin requirements on a daily basis for adverse movements in the U.S. dollar against the euro and in aluminum prices. There were no margin calls at June 30, 2025 and December 31, 2024.

At June 30, 2025, we had $841 million of total liquidity, comprised of $133 million in cash and cash equivalents, $465 million of availability under our Pan-U.S. ABL facility, $126 million of availability under our factoring arrangements and $117 million of availability under our French inventory facility.

Factored receivables under non-recourse arrangements were $410 million and $376 million at June 30, 2025 and December 31, 2024, respectively.

***Net Cash Flows from Operating Activities***

For the six months ended June 30, 2025, net cash flows from operating activities were $172 million, a $3 million decrease from $175 million in the six months ended June 30, 2024. This change primarily reflects a $31 million decrease in cash flows from operating activities before working capital and a $28 million reduction from working capital usage.

For the six months ended June 30, 2025, changes in working capital were attributable to (i) an increase in inventory of $65 million, primarily driven by higher ending metal prices; (ii) an increase in trade receivables of $261 million primarily driven by higher activity levels and higher ending metal prices; and (iii) an increase in trade payables of $241 million, primarily driven by increased metal purchases due to higher activity levels and higher ending metal prices.

For the six months ended June 30, 2024, changes in working capital were attributable to (i) an increase in inventory of $27 million, primarily driven higher ending metal prices; (ii) an increase in trade receivables of $241 million primarily driven by higher activity levels and higher ending metal prices, partially offset by $40 million of deferred purchase price receivables from factoring; and (iii) an increase in trade payables of $164 million, primarily driven by higher ending metal prices.

***Net Cash Flows used in Investing Activities***

For the six months ended June 30, 2025 and 2024, net cash flows used in investing activities were $131 million and $111 million, respectively. For the six months ended June 30, 2025 capital expenditures were $134 million. For the six months ended June 30, 2024 capital expenditures were $151 million and included the recycling investment in France. In the six months ended June 30, 2024, collection of deferred purchase price receivables from factoring was $40 million.

Capital expenditures by segment are detailed in Note 3.3 of our audited Consolidated Financial Statements.

***Net Cash Flows used in Financing Activities***

For the six months ended June 30, 2025, net cash flows used in financing activities were $62 million, primarily reflecting share repurchases, additional borrowings under the Pan-U.S. ABL facility and factoring arrangements in Europe as well as realized foreign exchange losses on net debt hedging instruments due to the weakening of the U.S. dollar. During the six months ended June 30, 2025, Constellium repurchased 4.8 million shares of the Company's ordinary shares for $50 million.

For the six months ended June 30, 2024, net cash flows used in financing activities were $51 million, primarily reflecting share repurchases. During the six months ended June 30, 2024, Constellium repurchased 1.9 million shares of the Company's ordinary shares for $39 million.

**Contractual obligations**

Except as otherwise disclosed in this Quarterly Report, there have been no changes in our material short-term and long-term contractual cash obligations other than in the ordinary course of business since December 31, 2024. See Note 15.4, Note 21 and Note 17 to our audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2024.

**Principal Accounting Policies, Critical Accounting Estimates and Key Judgments**

Our principal accounting policies are set out in Note 1 to our audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2024. New standards and interpretations not yet adopted are set out in Note 1 to the unaudited Consolidated Financial Statements, which appear elsewhere in this Quarterly Report.

The preparation of our consolidated financial statements requires management to make judgments, 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 Consolidated Financial Statements. Key sources of estimation uncertainty that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year include the items presented in Part II, Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations - Principal Accounting Policies, Critical Accounting Estimates and Key Judgments" of our Annual Report on Form 10-K for the year ended December 31, 2024. The Company continuously reviews its significant assumptions and estimates in light of the uncertainty associated with the global geopolitical and macroeconomic conditions and their potential direct and indirect impacts on its business and its financial statements. There can be no guarantee that our assumptions will materialize or that actual results will not differ materially from estimates. There have been no material changes in our critical accounting estimates since December 31, 2024.

**Recently Issued Accounting Standards** 

See Note 1- Basis of Presentation and Recent Accounting Pronouncements to our accompanying unaudited interim Consolidated Financial Statements for a full description of recent accounting pronouncements, if applicable, including the respective expected dates of adoption and expected effects on results of operations and financial condition.

**Non-GAAP measures**

Adjusted EBITDA is not a measure defined by GAAP. We believe the most directly comparable GAAP measure to Adjusted EBITDA is our net income or loss for the relevant period.

Adjusted EBITDA is defined as income/(loss) from continuing operations before income taxes, results from joint ventures, net finance costs, other expenses and depreciation and amortization as adjusted to exclude restructuring costs, impairment charges, unrealized gains or losses on derivatives and on foreign exchange differences on transactions that do not qualify for hedge accounting, share-based compensation expense, non-operating gains / (losses) on pension and other post-employment benefits, factoring expenses, effects of certain purchase accounting adjustments, start-up and development costs or acquisition, integration and separation costs, certain incremental costs and other exceptional, unusual or generally non-recurring items.

We believe Adjusted EBITDA, as defined above, is useful to investors as it illustrates the underlying performance of continuing operations by excluding certain non-recurring and non-operating items. Similar concepts of adjusted EBITDA are frequently used by securities analysts, investors and other interested parties in their evaluation of our company and in comparison, to other companies, many of which present an adjusted EBITDA-related performance measure when reporting their results.

Adjusted EBITDA has limitations as an analytical tool. It is not a measure defined by GAAP and therefore does not purport to be an alternative to operating profit or net income as a measure of operating performance or to cash flows from operating activities as a measure of liquidity. Adjusted EBITDA is not necessarily comparable to similarly titled measures used by other companies. As a result, you should not consider Adjusted EBITDA in isolation from, or as a substitute analysis for, our results prepared in accordance with GAAP.

<sup>1</sup>Adjusted EBITDA includes the non-cash impact of metal price lag

_______________

(A)For the three and six months ended June 30, 2024, impairment related to property, plant and equipment in our Valais operations.

(B)For the three months ended June 30, 2025, other mainly includes $2 million of clean-up costs related to the flooding of our facilities in Valais (Switzerland). For the six months ended June 30, 2025, Other mainly includes $9 million of insurance proceeds and $7 million of clean-up costs related to the flooding of our facilities in Valais (Switzerland). For the three and six months ended June 30, 2024, other was related to $6 million of inventory impairment as a result of the flooding of our facilities in Valais (Switzerland) at the end of June 2024 as well as $2 million of costs associated with non-recurring corporate transformation projects.

(C)Metal price lag represents the financial impact of the timing difference between when aluminum prices included within Constellium's Revenue are established and when aluminum purchase prices included in Cost of sales are established, which is a non-cash financial impact. The metal price lag will generally increase our earnings in times of rising primary aluminum prices and decrease our earnings in times of declining primary aluminum prices. The calculation of metal price lag adjustment is based on a standardized methodology applied at each of Constellium's manufacturing sites. Metal price lag is calculated as the average value of product purchased in the period, approximated at the market price, less the value of product in inventory at the weighted average of metal purchased over time, multiplied by the quantity sold in the period.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk**

In addition to the risks inherent in our operations, we are exposed to a variety market risks (including foreign currency exchange, interest rate and commodity price risk), and further information can be found in Item 7A. and Note 16 to our audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4 with Article L. 228-1, 7th subparagraph of the French Commercial Code. Shares registered on the French Register may be in "au nominatif" form or in "au porteur" form, at the shareholder's discretion, it being specified that these shares may not be traded in this form on the NYSE. On the effective date of the transfer of the registered office in France, all shares comprising the company's capital shall be entered in the U.S. Register.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5 The company reserves the right to share with the public and shareholders either the objectives that it has been notified of, or the relevant person's failure to comply with the aforementioned obligation. For the application of the preceding subparagraphs, the shares or voting rights listed in paragraphs 1 to 8 of Article L. 233-9 I of the French Commercial Code shall be considered equivalent to the shares or voting rights held by a person or an entity. Neither Cede & Co, acting on behalf of DTC, DTC, nor the intermediary acting as "intermédiaire inscrit" per subparagraph seven of Article L. 228-1 of the French Commercial Code are required to make the statements covered in this article, for all of the shares for which Cede & Co, DTC and such intermediary, respectively, are registered in such capacity in the books. ARTICLE 10 – MANDATORY PUBLIC OFFER Any natural or legal persons acting alone or in concert within the meaning of Article L. 233-10 of the French Commercial Code, who comes into possession, otherwise than following a voluntary takeover bid, directly or indirectly, of more than 30% of the equity securities or voting rights of the company, shall file a draft takeover bid on all the capital and securities granting access to the capital or voting rights, and on terms that comply with applicable U.S. Securities law, rules of the U.S. Securities and Exchange Commission (SEC) and NYSE rules. The same requirement applies to natural or legal persons, acting alone or in concert, who directly or indirectly own a number between 30% and half the total number of equity securities or voting rights of the company and who, in less than twelve consecutive months, increase the holding, in capital or voting rights, of at least 1% of the securities or voting rights of the company. When a draft offer is submitted, the price proposed must be at least equal to the highest price paid by the offeror, acting alone or in concert within the meaning of Article L. 233-10 of the French Commercial Code, over a period of twelve (12) months preceding the event giving rise to the obligation to submit the draft offer. In the event of a clear change in the characteristics of the company, if the market for its securities so justifies or in the absence of a transaction by the offeror, acting alone or in concert, over the company's shares during the twelve-month period mentioned in the first paragraph, the price will be fixed by an expert appointed in accordance with Article 1592 of the French Civil Code and determined according to the objective evaluation criteria usually used, the characteristics of the company and the market of its securities, it being specified that the expert will be required to take into account, in its assessment, the criteria identified by the French Commission des Opérations de Bourse, the French Autorité des Marchés Financiers ("AMF") and the French courts. The obligation to file a draft public offer does not apply if the person or persons concerned justify to the company the fulfilment of one of the conditions listed in Articles 234-7 and 234- 9 of the AMF's Règlement Général. In the event of disagreement between the parties, an expert will be appointed, at the request of the most diligent party, by the president of the commercial court, ruling in the form of interim relief, for the purpose of determining whether or not it is necessary to file a draft public offer, it being specified that the expert will be required to apply

![](exhibit31_cstmsexaoax15m006.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6 the relevant provisions of the AMF's Règlement Général as well as the criteria issued by the French Conseil des marchés financiers, the AMF and the French courts. Neither Cede & Co, acting on behalf of DTC, DTC, nor the intermediary acting as "intermédiaire inscrit" per subparagraph 7 of Article L. 228-1 of the French Commercial Code are subject to the requirements covered in this article, for all of the shares for which Cede & Co, DTC and such intermediary, respectively, are registered in such capacity in the books. ARTICLE 11 – RIGHTS AND OBLIGATIONS ATTACHED TO THE SHARES The rights and obligations attached to the share follow the share, in any hand it passes, and the transfer includes all dividends accrued, unpaid, and accruing, and, as applicable, the share of reserves and provisions. Share ownership entails, ipso facto, the holder's approval of these Articles of Association as well as of the decisions of the general meetings. The voting right attached to the company's shares shall be proportional to the percentage of the capital they represent, and each of the company's shares shall carry one vote. Each share entitles the holder, in the ownership of the company assets, profit-sharing, and liquidation surplus, to a percentage proportional to the number of existing shares, taking into account, as the case may be, the amortised and non-amortised capital, paid-up or unpaid capital, the nominal amount of the shares and the rights of the different categories of shares. Whenever it is necessary to own more than one share to exercise any right, the single shares or shares in fewer numbers than required shall confer no rights on their holders against the company, and in such cases the shareholders shall be personally responsible for pooling the required number of shares. TITLE III COMPANY ADMINISTRATION ARTICLE 12 – BOARD OF DIRECTORS 1. Composition The company shall be directed by a Board composed of natural or legal persons between three and eighteen in number, appointed by the general meeting. In the event of a merger, this number may be increased under the conditions provided by law. Any legal person shall, upon its appointment, assign a natural person as permanent representative to the Board of Directors. The permanent representative's term of office shall be the same as that of the legal person he or she is representing. If the legal person removes its permanent representative, it shall immediately provide a replacement. The same provisions apply in the event of the permanent representative's death or resignation. The general meeting may decide that the Board of Directors shall be renewed annually on a rotating basis, such that this rotation involves a given fraction of the number of directors.

------

![](exhibit31_cstmsexaoax15m007.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7 The directors' term of office is three (3) years renewable. By way of exception, (a) the general meeting may choose a director for a shorter term so that the renewal of the directors' terms of office may be spread out over time, (b) the directors in office immediately before the day of registration of the Company in the registre du commerce et des sociétés of Paris shall remain in office thereafter, for a duration equal to their remaining term of office before such registration. A director's term of office ends at the close of the ordinary general meeting called to approve the financial statements for the past financial year and held in the year during which the term of office of said director expires. Directors may be reappointed at any time. They may be removed at any time by a decision of the general meeting. In the event of a vacancy through the death or resignation of one or more directorships, the Board of Directors may make temporary appointments between two general meetings. The director appointed to replace another director whose term of office has not expired remains in office only for as long as the remaining term of his or her predecessor's office. A company employee may be appointed as a director. His or her employment contract must correspond to an actual position. In such cases he or she does not lose the benefit of his or her contract of employment. The number of directors bound to the company by a contract of employment may not exceed one-third (1/3) of the directors in office. The number of directors who are more than seventy-five (75) years of age shall not exceed one- third (1/3) of the directors in office. If this limit is exceeded during the terms of office, the oldest director shall automatically be considered to have resigned at the close of the next general meeting. The Board of Directors comprises also, in accordance with the provisions of Article L. 225-27- 1 of the French Commercial Code, directors representing employees and whose status is subject to the legal and regulatory provisions in force and to these Articles of Association. The preceding subparagraphs of this article 12.1 are not applicable to the directors representing employees. The number of directors representing employees is equal to one if the number of directors appointed by the general meeting referred to in Articles L. 225-17 and L. 225-18 of the French Commercial Code is less than or equal to eight at the time of the appointment of said director and to two if this number is greater than eight. Directors representing employees are not taken into account for determining the minimum number and the maximum number of directors set forth in the first subparagraph of this article 12.1. When only one director representing employees must be appointed, he or she is designated by the Group Works Council (French Group Works Council). When two directors representing employees must be appointed, the second director is designated, in accordance with Article L. 225-27-1, III, 4 ° of the French Commercial Code, by the European Works Council (designated SE-WC).

![](exhibit31_cstmsexaoax15m008.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8 The voting procedures within the Group Works Council and the European Works Council (designated SE-WC) for the appointment of directors representing employees are those applicable to the appointment of the secretaries of these Councils. The term of office of directors representing employees is three (3) years, renewable. The term of office of a director representing employees ends at the close of the ordinary general meeting of shareholders having approved the financial statements for the past financial year and held in the year during which the term of office said director expires. The term of office of a director representing the employees ends early under the conditions provided for by law and this article, and in particular in the event of termination of his or her employment contract (with the exception of intra-group mobility). If the conditions for applying Article L. 225-27-1 of the French Commercial Code are no longer met at the end of a financial year or if this Article is abrogated, the term of office of the director(s) representing employees ends at the close of the meeting during which the Board of Directors takes note of it. In the event of a vacancy for any reason whatsoever in a seat of a director representing employees, the vacant seat is filled in by an employee designated under the same condition as the replaced director representing employees, in accordance with Article L. 225-34 of the French Commercial Code. The term of office of a so appointed director representing employees ends at the expiry of the normal term of office of the other directors appointed in accordance with Article L. 225-27-1 of the French Commercial Code. It is specified that until the date of replacement of the director(s) representing employees, the Board of Directors may meet and validly deliberate The absence of appointment of the director(s) representing employees by the Council(s) referred to above, pursuant to law and this article, does not affect the validity of the deliberations of the Board of Directors. Directors representing employees are subject to the same obligations, particularly in terms of confidentiality, and incur the same responsibilities as other directors. 2. Chair – Bureau of the Board of Directors The Board of Directors elects a Chairman from among its members who must be a natural person. The Board of Directors sets his or her term office, which cannot exceed that of his or her directorship, and may remove him or her at any time. The Board sets his or her compensation. The Chairman organises and directs the tasks of the Board, which he or she then reports to the general meeting. He or she oversees the proper functioning of the various bodies of the company and, in particular, ensures that the directors are able to fulfil their mission. The Board Chairman may not be more than seventy-five (75) years of age. If the Chairman reaches that age during his or her term, he or she shall automatically be considered to have resigned. However, his or her term of office shall be extended until the next meeting of the Board of Directors during which his or her successor shall be appointed. Subject to this provision, the Board Chairman may be re-elected at any time.

------

![](exhibit31_cstmsexaoax15m009.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9 Moreover, the Board, if it sees fit, appoints a vice-chairman from among its members, whose term of office it sets within the limit of that of his or her directorship. The Board appoints a secretary, who may be chosen from outside the directors and shareholders. ARTICLE 13 – MEETING OF THE BOARD OF DIRECTORS The Board of Directors meets as often as required by the company's interests, at the registered office or at the location indicated in the convening notice, and at least every three (3) months. Directors shall be convened to Board meetings by the Chairman. Convocation may be made through any written means. The Chairman must convene the Board of Directors within seven (7) days following a reasoned request made in this sense by the Chief Executive Officer, if the offices of Chairman and Chief Executive Officer are separate, or at least one-third (1/3) of the members of the Board of Directors. If this request goes unanswered, the requesters may themselves convene the meeting, stating the agenda. Moreover, the directors representing at least one-third (1/3) of the Board members may validly convene the meeting if the Board of Directors has not met for more than two (2) months. In this case, they must state the meeting's agenda. The Board meets either at the company's registered office or in any other location in France or outside France. An attendance record shall be kept, and the minutes drawn up after each meeting. Meetings of the Board of Directors shall be chaired by the Board Chairman. In the event of the Chairman's absence or prevention, the Board of Directors shall entrust the Chairman's duties to the vice-chairman. In the event of the absence or prevention of these latter, the Board shall appoint one of its members to chair each meeting; if there is a tied vote for this appointment, the meeting shall be chaired by the eldest candidate. For the Board's deliberations to be valid, more than half of the Board members must be present or represented or have voted remotely or, as the case may be, have participated to a written consultation. The Board of Directors' decisions (including by way of a written consultation) shall be taken by a majority vote; if the votes are tied, the Chairman's vote shall be decisive. For the calculation of the quorum and majority, directors participating to a meeting by telecommunication means that allows them to be identified and guarantees their effective participation are considered present, under the terms and conditions provided for by the applicable laws. At the initiative of the convening person, directors may also vote remotely in accordance with the conditions provided for by applicable law. At the initiative of the convening person, decisions of the Board of Directors may also be taken

------

![](exhibit31_cstmsexaoax15m010.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10 by written consultation of the directors, including by electronic means, under the conditions and within the limits set forth by French Law and the terms of the notice. Directors are invited, at the request of the convening person, to resolve on the matter(s) submitted to them, within the time limit specified in the request. The convening person shall send to each director the text of the proposed resolutions as well as the documents necessary for the information of the directors. The directors must cast their vote or abstain within the time limit indicated in the consultation, which may not be less than three (3) business days from receipt of the consultation documents (or less if so provided in the consultation). Within the same time limit, each director will have the opportunity to explain his or her position, as the case may be. Any director may object to the use of a written consultation within two (2) business days from receipt of the consultation documents (or less if so provided in the consultation). In case of an objection within said time limit, the convening person shall immediately inform the other directors and may convene a Board meeting to resolve on the relevant decision(s). The consultation shall be closed in advance once all members have cast their votes. Any director who has not sent his/her response to the convening person within the applicable timeframe will be deemed absent and not having participated to the decision. In addition to the relevant provisions of these Articles of Association, the Board of Directors may adopt rules of procedure in order to organize its decision-making process and working method, including the rules in case of a conflict of interest. Each director receives the information required to perform his or her duties and, by virtue of his or her office, may obtain any and all documentation he or she deems useful. Any director may assign the power, even by letter, fax, or electronic mail, to another director to represent him or her in a Board meeting, but each director may only have one proxy during a meeting. Copies or extracts of the deliberations of the Board of Directors shall be validly certified by the Chairman of the Board of Directors, the Chief Executive Officer, the Deputy Chief Executive Officers, the director temporarily delegated to the duties of the chairman, or a proxy authorised for that purpose. ARTICLE 14 – POWERS AND DUTIES OF THE BOARD OF DIRECTORS The Board of Directors sets the guidelines for the company's activity and oversees their implementation, in accordance with its corporate interest, taking into consideration the social and environmental impact of its activity. Subject to the powers expressly assigned by law to the shareholders' meetings and within the limit of the corporate purpose, it hears any issue relevant to the company's smooth operation and, by means of its deliberations, settles the matters of concern to it. In its relations with third parties, the company shall be bound even by the decisions of the Board of Directors that do not come under the corporate purpose, unless the company can prove that the third party knew that the decision exceeded that purpose or that it could not have been unaware of this in light of the circumstances; publication of the Articles of Association alone does not constitute sufficient proof.

![](exhibit31_cstmsexaoax15m011.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11 The Board of Directors proceeds with the controls and checks that it deems advisable. Moreover, the Board of Directors exercises the special powers conferred on it by law. The Board of Directors may appoint, from within, one or more special committees, of which it sets the composition and powers and which carry out their activity under its responsibility. Each committee shall report on its missions at the next meeting of the Board of Directors. Directors, non-voting members, and any other person called to attend meetings of the Board of Directors are bound not to disclose, as applicable, even after the end of their duties, the information they have on the company and the disclosure of which could compromise the company's interests, except for cases in which such disclosure is required or allowed by law or in the public interest. ARTICLE 15 – GENERAL MANAGEMENT The company's executive management shall be assumed by a natural person appointed by the Board of Directors and given the title of Chief Executive Officer (directeur général). If the company's executive management is assumed by the Chairman (président), the laws, regulations, and statutes pertaining to the Chief Executive Officer shall be applicable to him or her. He or she shall take the title of Chairman and Chief Executive Officer (président-directeur général). The Chief Executive Officer shall be vested with the broadest powers to act in all circumstances in the company's name. He or she shall exercise his or her powers within the scope of the corporate purpose and subject to those that the law expressly assigns to shareholders' meetings and the Board of Directors. He or she shall represent the company in its relations with third parties. The company shall be bound even by the actions of the Chief Executive Officer that do not belong to the corporate purpose, unless it can prove that the third party knew that the decision exceeded that purpose or that it could not have been unaware of this in light of the circumstances; publication of the Articles of Association alone does not constitute sufficient proof. The Chief Executive Officer shall not be more than seventy (70) years of age. If the Chief Executive Officer reaches that age limit, he or she shall be considered to have resigned. However, his or her term of office shall be extended until the next meeting of the Board of Directors during which the new Chief Executive Officer is appointed. The Board of Directors may remove the Chief Executive Officer at any time. If the removal is approved without due cause, it may give rise to damages, unless the Chief Executive Officer is taking office as the Chairman of the Board of Directors. By a simple resolution passed by a majority vote of the directors present or represented, the Board of Directors shall choose whether the general management of the company is to be assumed by the Chairman of the Board or by another natural person. Shareholders and third parties shall be informed of this choice in accordance with the laws and regulations.

------

![](exhibit31_cstmsexaoax15m012.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12 The Board of Directors' choice thus made shall remain in force until an opposing decision by the Board or, at the Board's discretion, throughout the Chief Executive Officer's term of office. If the company's general management is assumed by the Chairman of the Board of Directors, the provisions applicable to the Chief Executive Officer shall be applicable to him or her. On a proposal by the Chief Executive Officer, the Board of Directors may appoint one or more natural persons to assist the Chief Executive Officer as Deputy Chief Executive Officer (directeur général délégué). In agreement with the Chief Executive Officer, the Board of Directors shall set the scope and duration of the powers conferred on the Deputy Chief Executive Officers. The Board of Directors shall set their compensation. If a Deputy Chief Executive Officer is a director, his or her duties cannot outlast his or her directorship. With regard to third parties, Deputy Chief Executive Officers have the same powers as the Chief Executive Officer; Deputy Chief Executive Officers have the power to litigate. The number of Deputy Chief Executive Officers may not exceed five. The Deputy Chief Executive Officer(s) shall be removable at any time by the Board of Directors, as proposed by the Chief Executive Officer. If the removal is approved without due cause, it may give rise to damages. A Deputy Chief Executive Officer may not be more than seventy (70) years of age. If a Deputy Chief Executive Officer in office reaches that age limit, he or she shall automatically be considered to have resigned. However, his or her term of office shall be extended until the next meeting of the Board of Directors during which a new Deputy Chief Executive Officer could potentially be appointed. If the Chief Executive Officer ceases to perform or is prevented from performing his or her duties, the Deputy Chief Executive Officer(s) shall retain all duties and powers until the appointment of the new Chief Executive Officer, unless decided otherwise by the Board of Directors. ARTICLE 16 – NON-VOTING MEMBERS The Board of Directors may appoint one or more non-voting members (censeurs) from among the shareholders, natural or legal persons, or elsewhere, but they shall not be more than two (2) in number. The non-voting members' term of office shall be set by the Board of Directors, not to exceed three (3) years. The duties of a non-voting member shall end at the close of the ordinary general meeting called to approve the financial statements for the past year and held in the year during which the term of office of said non-voting member expires. Non-voting members may be re-elected at any time. The Board of Directors may put an end to their term of office at any time. In the event of the death, resignation, or severance of a non-voting member for any other reason,

![](exhibit31_cstmsexaoax15m013.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13 the Board of Directors may replace him or her for the remainder of his or her term of office. Non-voting members shall be called upon to attend meetings of the Board of Directors as observers and may be consulted by the latter or by the Chairman and take part in the deliberations with a consultative voice only; however their absence cannot affect the validity of the deliberations. They shall be convened to Board meetings under the same conditions as directors. Non-voting members shall not be remunerated for their duties. However, the Board of Directors may authorise the reimbursement of the expenses that the non-voting members incur in the company's interest. ARTICLE 17 – INDEMNIFICATION OF DIRECTORS The members and former members of the Board of Directors shall be reimbursed for: (a) reasonable cost of conducting a defense against claims, including claims by the company (other than such claims for which such members or former members of the Board have been declared responsible for by a final court decision), based on acts or failures to act in the exercise of their duties or any other duties currently or previously performed by them at the company's request; and (b) any damages payable by them as a result of an act or failure to act in the exercise of their duties or any other duties currently or previously performed by them at the company's request. There shall be no entitlement to indemnity: (a) if and to the extent the laws of France would not permit such indemnification; (b) if and to the extent a competent court has established in a final and conclusive decision that the act or failure to act of the current or former member of the Board may be characterized as willful (faute intentionnelle), intentionally reckless (faute lourde) or falling outside the exercise of its duties (faute détachable); or (c) if and to the extent the costs, damages or fines payable by the current or former member of the Board are covered by any liability insurance and the insurer has paid out the costs, damages or fines. Except if the claim is instituted by the company itself, the relevant current or former member of the Board of Directors shall follow the company's instructions relating to the manner of his or her defense and consult with the company in advance about the manner of such defense. The person concerned shall not: (i) acknowledge any personal liability, (ii) waive any defense, or (iii) agree on a settlement, without the company's prior written consent. The company may take out liability insurance for the benefit of current or former members of the Board. ARTICLE 18 – RELATED-PARTY AGREEMENTS Pursuant to subparagraph 6 of Article L. 229-7 of the French Commercial Code, Articles L. 225- 38 to L. 225-42 of the said Commercial Code are applicable to agreements entered into by the company.

The latter will then be drawn up by the general meeting committee after the aforementioned information has been taken into account. Votes cast by shareholders who have disposed of their shares before the record date provided for by French law will be invalidated or modified, whichever is appropriate. Copies or extracts of the meeting minutes shall be validly certified by the Chairman of the Board of Directors, by a director performing the duties of Chief Executive Officer, or by the meeting secretary. 5.

The ordinary general meeting held on the date set by the first convening notice validly deliberates where the shareholders present, represented or having voted by correspondence hold at least one-fifth (1/5) of the voting shares. If this quorum is not reached, a second meeting is convened with an agenda identical to the first meeting; no quorum is required for such second meeting. The extraordinary general meeting held on the date set by the first convening notice validly deliberates where the shareholders present, represented or having voted by correspondence hold at least a quarter (1/4) of the voting shares. If this quorum is not reached, a second meeting is convened with an agenda identical to the first meeting. If the quorum at the second meeting is not reached, the second meeting can be postponed to a date no later than two months after the date on which the second meeting was convened. The quorum for such second or postponed meeting, as the case may be, to be validly held is 1/5 of the voting shares. Special meetings held on the date set by the first convening notice may validly deliberate where the shareholders present, represented or having voted by correspondence hold at least one third (1/3), on first notice, and, failing which, 1/5 for the meeting held on the date set by the second convening notice or in the case of postponement of the second meeting. The ordinary general meeting's decisions shall be made by a majority of votes validly cast. Decisions of the extraordinary general meetings and special meetings shall be made by a two- thirds (2/3) majority of votes validly cast. Votes cast shall not include those attached to shares for which the shareholder has not taken part in voting or has abstained or has returned a blank or invalid vote. TITLE VI COMPANY RESULTS ARTICLE 21 – FINANCIAL YEAR Each financial year shall last one calendar year, beginning on 1 January and ending on 31 December. ARTICLE 22 – PROFITS - LEGAL RESERVE A mandatory deduction of five percent (5%) of the profit for the financial year, minus any prior losses, shall be allocated to creating a reserve fund known as the "legal reserve."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17 Distributable profit shall comprise profit for the financial year, minus any prior losses and the deduction stipulated in the preceding subparagraph, plus accumulated profit. ARTICLE 23 – DIVIDENDS If the financial statements for the year, as approved by the general meeting, show a distributable profit, the general meeting shall decide to enter it in one or more reserve accounts of which it governs the allocation or use, to carry it forward, or to distribute it as dividends. After recording the existence of reserves available to it, the general meeting may decide to distribute funds deducted from those reserves. In this case, the decision shall expressly indicate the reserve accounts from which these deductions are made. However, dividends shall first be deducted from the distributable profit for the financial year. The procedures for issuing payment of dividends shall be set by the general meeting or by the Board of Directors, as appropriate. Distributions payable in cash shall be approved in euro and paid (i) in euro for all holders of shares held on the French Register and (ii) in U.S. dollars (USD) for all holders of shares entered in the U.S. Register. For the purposes of paying the dividend in dollars, the general meeting or, as appropriate, the Board of Directors shall set the reference date to be applied for the EUR/USD conversion price. Dividend payment shall be issued no later than nine (9) months after the close of the financial year. The general meeting approving the financial statements for the year may grant each shareholder, for some or all of the dividend being distributed, the choice of cash or shares in payment of the dividend. Likewise, each shareholder may be granted an interim distribution, and for some or all of said interim distribution, the choice of cash or shares in payment of the interim distribution. The offer of payment in shares, the price, and the conditions for issuing the shares, as well as the request for payment in shares and the conditions for the capital increase, shall be governed by the laws and regulations in force. The Board of Directors may decide to carry out interim distributions under the conditions set out by the laws and regulations in force. TITLE VII DISSOLUTION · LIQUIDATION ARTICLE 24 – EARLY DISSOLUTION The extraordinary general meeting may decide on the company's early dissolution at any point in time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18 ARTICLE 25 – LOSS OF ONE-HALF OF CAPITAL If, due to losses recorded in the accounting documents, the shareholders' equity falls below one- half of the registered capital, the Board of Directors shall, within four months from approval of the financial statements showing such a loss, convene the extraordinary general meeting for the purpose of deciding whether the early dissolution of the company is justified. If the decision is not made to dissolve, the capital shall, no later than the closure of the second financial year following the one during which the losses were recorded, and subject to the laws relating to the minimum capital of sociétés anonymes, be reduced by an amount equal to or greater than any losses that could not be charged against the reserves, if, during that period, the equity capital has not been restored to a value equal to or greater than one-half of the capital. If the general meeting is not held, or if that meeting fails to validly deliberate, any interested party may petition the court for the company's dissolution. ARTICLE 26 – EFFECTS OF DISSOLUTION The company shall be in liquidation from the moment it is dissolved for any reason whatsoever. Its legal personality shall persist for the purposes of this liquidation until the closure thereof. Throughout the liquidation period, the general meeting shall retain the same powers as it had during the company's existence. Shares shall remain tradeable until the closure of the liquidation. The company's dissolution shall only have effect with respect to third parties from the date on which said dissolution is published in the trade and corporate register. ARTICLE 27 – APPOINTMENT OF LIQUIDATORS – POWERS At the expiration of the company's duration or in the event of early dissolution, the general meeting shall govern the mode of liquidation and appoint one or more liquidators, whose powers it shall set and who shall perform their duties in compliance with the law. The appointment of liquidators puts an end to the duties of the directors, the Chairman, the Chief Executive Officer, and the Deputy Chief Executive Officers. TITLE VIII NOTIFICATIONS ARTICLE 28 All notifications provided under these Articles of Association shall be made by certified letter with acknowledgement of receipt or by extrajudicial act. Simultaneously, a duplicate of the notification shall be sent to its recipient by regular mail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19 TITLE IX DISPUTES ARTICLE 29 Any disputes that may arise during the life of the company or its liquidation, either among shareholders or between the company and the shareholders, as to the construal or execution of these Articles of Association or, generally, regarding company matters, shall fall within the jurisdiction of the competent courts of the location of the registered office. As such, in case of a dispute, each shareholder must elect domicile under the jurisdiction of the competent court of the location of the registered office, and all summons and notices shall be lawfully issued to this domicile. If no domicile is elected, the summons and notices shall be validly made to the Office of the Public Prosecutor (Procureur de la République) of the regional court (Tribunal de Grande Instance) of the location of the registered office.
