Item 3. Key Information

The following tables set forth our selected historical financial and operating data.

On January 4, 2011, Omega Holdco B.V., which later changed its name to Constellium Holdco B.V., and then again to Constellium N.V. (“Constellium”) acquired the Engineered Aluminum Products business unit (the “EAP Business”) from affiliates of Rio Tinto, a leading international mining group (the “Acquisition”).

The selected historical financial information as of December 31, 2015 and 2014 and for each of the three years in the period ended December 31, 2015 has been derived from our audited consolidated financial statements included elsewhere in this Annual Report. The selected historical financial information as of December 31, 2013, 2012, and 2011 and for each of the two years in the period ended December 31, 2012 have been derived from our audited consolidated financial statements not included in this Annual Report.

The audited consolidated financial statements included elsewhere in this Annual Report have been prepared in a manner that complies, in all material respects, with the International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (the “IASB”), and as endorsed by the European Union (“EU”).

Effective January 1, 2013, we have adopted IAS 19 “Employee Benefits” (revised) (IAS 19) in our audited consolidated financial statements as of and for the year ended December 31, 2013 and in accordance with transition rules in IAS 19 we have retrospectively applied this standard to the two years ending December 31, 2012 and 2011.

Effective January 1, 2014, we changed the measure of profitability for our segments under IFRS 8 Operating Segments from Management Adjusted EBITDA to Adjusted EBITDA.

References to “tons” throughout this Annual Report are to metric tons.

Risks Related to Our Business

If we fail to implement our business strategy, including our productivity and Lean initiatives, our financial condition and results of operations could be materially adversely affected.

Our future financial performance and success depend in large part on our ability to successfully implement our business strategy, including investing in high-return opportunities in our core markets, focusing on higher-margin, technologically advanced products, differentiating our products, expanding our strategic relationships with customers in selected international regions, fixed-cost containment and cash management, and executing on our Lean manufacturing program. We cannot assure you that we will be able to successfully implement our business strategy or be able to continue improving our operating results.

Implementation of our business strategy could be affected by a number of factors beyond our control, such as increased competition, legal and regulatory developments, or general economic conditions (including slower or lower than expected growth in North America for BiW aluminium rolled products). Any failure to successfully implement our business strategy could adversely affect our financial condition and results of operations. In addition, we may decide to alter or discontinue certain aspects of our business strategy at any time. Although we have undertaken and expect to continue to undertake productivity and manufacturing system and process transformation initiatives to improve performance, such as the Lean manufacturing program, we cannot assure you that all of these initiatives will be completed or that any estimated cost savings from such activities will be fully realized. Even when we are able to generate new efficiencies in the short- to medium-term, we may not be able to continue to reduce costs and increase productivity over the long term.

Aluminium may become less competitive with alternative materials, which could reduce our share of industry sales, lower our selling prices and reduce our sales volumes.

Our fabricated aluminium products compete with products made from other materials—such as steel, glass, plastics and composites—for various applications. Higher aluminium prices relative to substitute materials tend to make aluminium products less competitive with these alternative materials. Environmental and other regulations may also increase our costs and may be passed on to our customers, and may restrict the use of chemicals needed to produce aluminium products. These regulations may make our products less competitive as compared to materials that are subject to fewer regulations.

Customers in our end-markets, including the can, aerospace and automotive sectors, use and continue to evaluate the further use of alternative materials to aluminium in order to reduce the weight and increase the efficiency of their products. Although trends in “light-weighting” have generally increased rates of using aluminium as a substitution of other materials, the willingness of customers to accept substitutions for aluminium, or the ability of large customers to exert leverage in the marketplace to reduce the pricing for fabricated aluminium products, could adversely affect the demand for our products, and thus materially adversely affect our financial position, results of operations and cash flows.

The cyclical and seasonal nature of the metals industry, our end-use markets and our customers’ industries could negatively affect our financial condition and results of operations.

The metals industry is generally cyclical in nature, and these cyclical fluctuations tend to directly correlate with changes in general and local economic conditions. These conditions include the level of economic growth, financing availability, the availability of affordable energy sources, employment levels, interest rates, consumer confidence and housing demand. Historically, in periods of recession or periods of minimal economic growth, metals companies have often tended to underperform other sectors. In addition, economic downturns in regional and global economies, including in Europe, or a prolonged recession in our principal industry segments, have had a negative impact on our operations in the past and could have a negative impact on our future financial

condition or results of operations. Although we continue to seek to diversify our business on a geographic and end-market basis, we cannot assure you that diversification would mitigate the effect of cyclical downturns.

We are particularly sensitive to cycles in the aerospace, defense, automotive, other transportation, building and construction and general engineering end-markets, which are highly cyclical. During recessions or periods of low growth, these industries typically experience major cutbacks in production, resulting in decreased demand for aluminium products. This leads to significant fluctuations in demand and pricing for our products and services. Because our operations are capital intensive and we generally have high fixed costs and may not be able to reduce costs and production capacity on a sufficiently rapid basis, our near-term profitability may be significantly affected by decreased processing volumes. Accordingly, reduced demand and pricing pressures may significantly reduce our profitability and materially adversely affect our financial condition, results of operations and cash flows.

In particular, we derive a significant portion of our revenues from products sold to the aerospace industry, which is highly cyclical and tends to decline in response to overall declines in the general economy. The commercial aerospace industry is historically driven by the demand from commercial airlines for new aircraft. Demand for commercial aircraft is influenced by airline industry profitability, trends in airline passenger traffic, the state of the U.S. and global economies and numerous other factors, including the effects of terrorism. A number of major airlines have undergone Chapter 11 bankruptcy or comparable insolvency proceedings and experienced financial strain from volatile fuel prices. The aerospace industry also suffered significantly in the wake of the events of September 11, 2001, resulting in a sharp decrease globally in new commercial aircraft deliveries and order cancellations or deferrals by the major airlines. Despite existing backlogs, continued financial uncertainty in the industry, inadequate liquidity of certain airline companies, production issues and delays in the launch of new aircraft programs at major aircraft manufacturers, stock variations in the supply chain, terrorist acts or the increased threat of terrorism may lead to reduced demand for new aircraft that utilize our products, which could materially adversely affect our financial position, results of operations and cash flows.

Further, the demand for our automotive extrusions and rolled products and many of our general engineering and other industrial products is dependent on the production of cars, light trucks, and heavy duty vehicles and trailers. The automotive industry is highly cyclical, as new vehicle demand is dependent on consumer spending and is tied closely to the strength of the overall economy. We note that the demand for luxury vehicles in China has become significant over the past several years and therefore fluctuations in the Chinese economy may adversely affect the demand for our products. Production cuts by manufacturers may adversely affect the demand for our products. Many automotive-related manufacturers and first tier suppliers are burdened with substantial structural costs, including pension, healthcare and labor costs that have resulted in severe financial difficulty, including bankruptcy, for several of them. A worsening of these companies’ financial condition or their bankruptcy could have further serious effects on the conditions of the markets, which directly affects the demand for our products. In addition, the loss of business with respect to, or a lack of commercial success of, one or more particular vehicle models for which we are a significant supplier could have a materially adverse impact on our financial position, results of operations and cash flows.

Customer demand in the aluminium industry is also affected by holiday seasons, weather conditions, economic and other factors beyond our control. Our volumes are impacted by the timing of the holiday seasons in particular, with August and December typically being the lowest months and January to June being the strongest months. Our business is also impacted by seasonal slowdowns and upturns in certain of our customers’ industries. Historically, the can industry is strongest in the spring and summer season, whereas the automotive and construction sectors encounter slowdowns in both the third and fourth quarters of the calendar year. Therefore, our quarterly financial results could fluctuate as a result of climatic or other seasonal changes, and a prolonged period of unusually cool summers in different regions in which we conduct our business could have a negative effect on our financial results and cash flows.

We may not be able to compete successfully in the highly competitive markets in which we operate, and new competitors could emerge, which could negatively impact our share of industry sales, sales volumes and selling prices.

We are engaged in a highly competitive industry. We compete in the production and sale of rolled aluminium products with a number of other aluminium rolling mills, including large, single-purpose sheet mills, continuous casters and other multi-purpose mills, some of which are larger and have greater financial and technical resources than we do. Producers with a different cost basis may, in certain circumstances, have a competitive pricing advantage. Our competitors may be better able to withstand reductions in price or other adverse industry or economic conditions.

In addition, a current or new competitor may also add or build new capacity, which could diminish our profitability by decreasing equilibrium prices in our marketplace. New competitors could emerge from within Europe or North America or globally, including from China, Russia and the Middle East, and could include existing producers and sellers of steel products that may seek to compete in our industry. Emerging or transitioning markets in these regions with abundant natural resources, low-cost labor and energy, and lower environmental and other standards may pose a significant competitive threat to our business. Our competitive position may also be affected by exchange rate fluctuations that may make our products less competitive. Changes in regulation that have a disproportionately negative effect on us or our methods of production may also diminish our competitive advantage and industry position. In addition, technological innovation is important to our customers who require us to lead or keep pace with new innovations to address their needs. If we do not compete successfully, our share of industry sales, sales volumes and selling prices may be negatively impacted.

In addition, the aluminium industry has experienced consolidation over the past years and there may be further industry consolidation in the future. Although industry consolidation has not yet had a significant negative impact on our business, if we do not have sufficient market presence or are unable to differentiate ourselves from our competitors, we may not be able to compete successfully against other companies. If as a result of consolidation, our competitors are able to obtain more favorable terms from suppliers or otherwise take actions that could increase their competitive strengths, our competitive position and therefore our business, results of operations and financial condition may be materially adversely affected.

The beverage can sheet industry is competitive, and our competitors have greater resources and product and geographic diversity than we do.

The market for beverage can sheet products is competitive. Our competitors have market presence, operating capabilities and financial and other resources that are greater than ours. They also have greater product and geographic diversity than we do. Because of their greater resources and product and geographic diversity, these competitors may have an advantage over us in their abilities to research and develop technology, pursue acquisition, investment and other business opportunities, market and sell their products and services, capitalize on market opportunities, enter new markets and withstand business interruptions or adverse global economic conditions. There are no assurances that we will be able to compete successfully in these circumstances.

In addition, we are subject to competition from non-aluminium sources of packaging, such as plastics and glass. Consumer demand and preferences also impact customer selection of packaging materials. While we believe that the recyclability of aluminium, coupled with increasing consumer focus on resource conservation, may reduce the impact of competition from certain alternative packaging sources, there is no guaranty that such competition will be reduced.

Our business involves significant activity in Europe, and adverse conditions and disruptions in European economies could have a material adverse effect on our operations or financial performance.

A material portion of our sales are generated by customers located in Europe. The financial markets remain concerned about the ability of certain European countries to finance their deficits and service growing debt burdens amidst difficult economic conditions. This loss of confidence has led to rescue measures by Eurozone

-7-

Table of Contents

countries and the International Monetary Fund. Despite these measures, concerns persist regarding the debt burden of certain Eurozone countries and their ability to meet future financial obligations, the overall stability of the euro and the suitability of the euro as a single currency given the diverse economic and political circumstances in individual Eurozone countries. In addition, the actions required to be taken by those countries as a condition to rescue packages, and by other countries to mitigate similar developments in their economies, have resulted in increased political discord within and among Eurozone countries. The interdependencies among European economies and financial institutions have also exacerbated concern regarding the stability of European financial markets generally. These concerns could lead to the re-introduction of individual currencies in one or more Eurozone countries, or, in more extreme circumstances, the possible dissolution of the euro currency entirely. Should the euro dissolve entirely, the legal and contractual consequences for holders of euro-denominated obligations would be determined by laws in effect at such time. These potential developments, or market perceptions concerning these and related issues, could materially adversely affect the value of the Company’s euro-denominated assets and obligations. In addition, concerns over the effect of this financial crisis on financial institutions in Europe and globally could have a material adverse impact on the capital markets generally. Persistent disruptions in the European financial markets, the overall stability of the euro and the suitability of the euro as a single currency or the failure of a significant European financial institution, could have a material adverse impact on our operations or financial performance.

In addition, there can be no assurance that the actions we have taken or may take in response to global economic conditions may be sufficient to counter any continuation or reoccurrence of the downturn or disruptions. A significant global economic downturn or disruptions in the financial markets would have a material adverse effect on our financial position, results of operations and cash flows.

Adverse changes in currency exchange rates could negatively affect our financial results.

The financial condition and results of operations of some of our operating entities are reported in various currencies and then translated into euros at the applicable exchange rate for inclusion in our consolidated financial statements. As a result, the appreciation of the euro against the currencies of our operating local entities may have a negative impact on reported revenues and operating profit, and the resulting accounts receivable, while depreciation of the euro against these currencies may generally have a positive effect on reported revenues and operating profit. We do not hedge translation of forecasted results or actual results.

In addition, while the majority of costs incurred are denominated in local currencies, a portion of the revenues are denominated in U.S. dollars and other currencies. As a result, appreciation in the U.S. dollar may have a positive impact on earnings while depreciation of the U.S. dollar may have a negative impact on earnings. While we engage in significant hedging activity to attempt to mitigate this foreign transactions currency risk, this may not fully protect us from adverse effects due to currency fluctuations on our business, financial condition or results of operations.

A portion of our revenues is derived from our international operations, which exposes us to certain risks inherent in doing business globally.

We have operations primarily in the United States, Germany, France, Slovakia, Switzerland, the Czech Republic and China and primarily sell our products across Europe, Asia and North America. We also continue to explore opportunities to expand our international operations. Our operations generally are subject to financial, political, economic and business risks in connection with our global operations, including:

The occurrence of any of these events could cause our costs to rise, limit growth opportunities or have a negative effect on our operations and our ability to plan for future periods. In certain emerging markets, the degree of these risks may be higher due to more volatile economic conditions, less developed and predictable legal and regulatory regimes and increased potential for various types of adverse governmental action.

We are dependent on a limited number of suppliers for a substantial portion of our aluminium supply and a failure to successfully renew, renegotiate or re-price our long-term agreements or related arrangements with our suppliers may adversely affect our results of operations, financial condition and cash flows.

Our ability to produce competitively priced aluminium products depends on our ability to procure competitively priced supply of aluminium in a timely manner and in sufficient quantities to meet our production needs. We have supply arrangements with a limited number of suppliers for aluminium and other raw materials. Our top 10 suppliers accounted for approximately 45% of our total purchases for the year ended December 31, 2015. Increasing aluminium demand levels have caused regional supply constraints in the industry, and further increases in demand levels could exacerbate these issues. We maintain long-term contracts for a majority of our supply requirements, and for the remainder we depend on annual and spot purchases. There can be no assurance that we will be able to renew, or obtain replacements for, any of our long-term contracts or any related arrangements when they expire on terms that are as favorable as our existing agreements or at all. Additionally, if any of our key suppliers is unable to deliver sufficient quantities of this material on a timely basis, our production may be disrupted and we could be forced to purchase primary metal and other supplies from alternative sources, which may not be available in sufficient quantities or may only be available on terms that are less favorable to us. As a result, an interruption in key supplies required for our operations could have a material adverse effect on our ability to produce and deliver products on a timely or cost-efficient basis and therefore on our financial condition, results of operations and cash flows. In addition, a significant downturn in the business or financial condition of our significant suppliers exposes us to the risk of default by the supplier on our contractual agreements, and this risk is increased by weak and deteriorating economic conditions on a global, regional or industry sector level.

We depend on scrap aluminium for our operations and acquire our scrap inventory from numerous sources. Our suppliers generally are not bound by long-term contracts and have no obligation to sell scrap metal to us. In periods of low inventory prices, suppliers may elect to hold scrap until they are able to charge higher prices. In addition, a decrease in the supply of used beverage containers (“UBCs”) available to us resulting from a decrease in the rate at which consumers consume or recycle products contained or packaged in aluminium beverage cans could negatively impact our supply of aluminium. For example, the slowdown in industrial production and consumer consumption during the recent economic crisis reduced and may continue to reduce the supply of scrap metal available. If an adequate supply of scrap metal is not available to us, we would be unable to recycle metals at desired volumes and our results of operation, financial condition and cash flows could be materially adversely affected.

In addition, we seek to take advantage of the lower price of scrap aluminium compared to primary aluminium to provide a cost-competitive product. A decrease in the supply of scrap aluminium could increase its cost per pound. To the extent the discount between the primary aluminium price and scrap price narrows, our competitive advantage may be reduced. We cannot make use of financial markets to effectively hedge against

-9-

Table of Contents

reductions in this discount as this market is not readily available. If the difference between the price of primary and scrap aluminium is narrow for a considerable period of time, it could adversely affect our business, financial condition and results of operations.

Our financial results could be adversely affected by the volatility in aluminium prices.

The overall price of primary aluminium consists of several components: (1) the underlying base metal component, which is typically based on quoted prices from the London Metal Exchange (“LME”); (2) the regional premium, which represents an incremental price over the base LME component that is associated with the physical delivery of metal to a particular region (e.g., the Midwest premium for metal sold in the U.S. or the Rotterdam premium for metal sold in Europe); and (3) the product premium, which represents a separate incremental price for receiving physical metal in a particular shape (e.g., billet, slab, rod, etc.), alloy, or purity. Each of these three components has its own drivers of variability. The LME price is typically driven by macroeconomic factors, global supply and demand of aluminium, including expectations for growth and contraction and the level of global inventories. Regional premiums tend to vary based on the supply and demand for metal in a particular region and associated warehousing and transportation costs. Product premiums generally are a function of supply and demand as well as production and raw material costs for a given primary aluminium shape and alloy combination in a particular region.

Speculative trading in aluminium has increased in recent years, contributing to higher levels of price volatility. In 2015, the LME cash price of aluminium reached a high of $1,919 per metric ton and a low of $1,424 per metric ton compared to a high of $2,114 and a low of $1,642 per metric ton in 2014. During 2014, regional premiums reached levels substantially higher than historical averages, whereas in 2015, such premiums experienced significant decreases in all regions, reverting to levels that are closer to historical averages. The Rotterdam regional premium increased from an average of 3% of the LME base price in the period from 2000 to 2009 to 26% of the LME base price in December 2014. The Midwest regional premium increased from an average of 6% of the LME base price to 27% of the LME base price during the same periods. New LME warehousing rules, which took effect in February 2015, and increasing exports from China led to an increase in the supply of aluminium entering the physical market and in turn caused regional premiums to decrease sharply between February and April 2015 to reach 11% of the LME base price for the Rotterdam regional premium and to 13% of the LME base price for the Midwest regional premium in December 2015. Sustained high aluminium prices, increases in aluminium prices, the inability to meaningfully hedge our exposure to aluminium prices, or the inability to pass through any fluctuation in regional premiums or product premiums to our customers could have a material adverse effect on our business, financial condition, and results of operations and cash flow.

If we are unable to adequately mitigate the cost of price increases of our raw materials, including aluminium, our profitability could be adversely affected.

Prices for the raw materials we require are subject to continuous volatility and may increase from time to time. Although our sales are generally made on a “margin over metal price” basis, if prices increase we may not be able to pass on the entire cost of the increases to our customers. There could also be a time lag between when changes in prices under our purchase contracts are effective and the point when we can implement corresponding changes under our sales contracts with our customers. As a result, we are exposed to fluctuations in raw materials prices, including metal, since during this time lag we may have to temporarily bear the additional cost of the price change under our purchase contracts. Further, although most of our contracts allow us to pass through metal prices to our customers, we have certain contracts that are based on fixed metal pricing where pass through is not available. Similarly, in certain contracts we have ineffective pass through mechanisms related to Midwest regional premium fluctuation. A related risk is that a sustained significant increase in raw materials prices may cause some of our customers to substitute our products with other materials. We attempt to mitigate these risks, including through hedging, but we may not be able to successfully reduce or eliminate any resulting negative impact, which could have a material adverse effect on our profitability and financial results.

Our results of operations, cash flows and liquidity could be adversely affected if we are unable to execute on our hedging policy, if counterparties to our derivative instruments fail to honor their agreements or if we are unable to purchase derivative instruments.

We purchase and sell LME and other forwards, futures and options contracts as part of our efforts to reduce our exposure to changes in currency exchange rates, aluminium prices and other raw materials prices. If we are unable to purchase derivative instruments to manage those risks due to the cost or availability of such instruments or other factors, or if we are not successful in passing through the costs of our risk management activities, our results of operations, cash flows and liquidity could be adversely affected. Our ability to realize the benefit of our hedging program is dependent upon many factors, including factors that are beyond our control. For example, our foreign exchange hedges are scheduled to mature on the expected payment date by the customer; therefore, if the customer fails to pay an invoice on time and does not warn us in advance, we may be unable to reschedule the maturity date of the foreign exchange hedge, which could result in an outflow of foreign currency that will not be offset until the customer makes the payment. We may realize a gain or a loss in unwinding such hedges. In addition, our metal-price hedging programs depend on our ability to match our monthly exposure to sold and purchased metal, which can be made difficult by seasonal variations in metal demand, unplanned changes in metal delivery dates by either us or by our customers and other disruptions to our inventories, including for maintenance. In 2015, we were unable to hedge all of our exposure to the increase in the Midwest regional premium component of aluminium prices, resulting in unrecovered Midwest premium charges of €22 million at Wise.

We may also be exposed to losses if the counterparties to our derivative instruments fail to honor their agreements. Further, if major financial institutions continue to consolidate and are forced to operate under more restrictive capital constraints and regulations, there could be less liquidity in the derivative markets, which could have a negative effect on our ability to hedge and transact with creditworthy counterparties.

To the extent our hedging transactions fix prices or exchange rates, if primary aluminium prices, energy costs or foreign exchange rates are below the fixed prices or rates established by our hedging transactions, then our income and cash flows will be lower than they otherwise would have been. Similarly, if we do not adequately hedge for prices and premiums (including the Midwest regional premium) of our aluminium and other raw materials, our financial results may also be negatively impacted. Further, we do not apply hedge accounting to our forwards, futures or option contracts. As a result, unrealized gains and losses on our derivative financial instruments must be reported in our consolidated results of operations. The inclusion of such unrealized gains and losses in earnings may produce significant period over period earnings volatility that is not necessarily reflective of our underlying operating performance. In addition, in certain scenarios when market price movements result in a decline in value of our current derivatives position, our mark-to-market expense may exceed our credit line and counterparties may request the posting of cash collateral which, in turn, can be a significant demand on our liquidity.

At certain times, hedging instruments may simply be unavailable or not available on terms acceptable to us. In addition, recent legislation has been adopted to increase the regulatory oversight of over-the-counter derivatives markets and derivative transactions. The companies and transactions that are subject to these regulations may change. If future regulations subject us to additional capital or margin requirements or other restrictions on our trading and commodity positions, this could have an adverse effect on our financial condition and results of operations.

Our production capacity might not be able to meet growing market demand or changing market conditions.

We may be unable to meet market demand due to production capacity constraints or operational challenges. Meeting such demand may require us to make substantial capital investments to repair, maintain, upgrade, and expand our facilities and equipment. We intend to invest to increase Wise’s current hot mill capacity and we also

recently announced that we executed a Term Sheet with UACJ to expand our joint venture with UACJ to produce automotive BiW sheet in the U.S., and to establish a leadership position in the growing North American BiW market. We also intend to install a new pusher furnace at our Ravenswood, West Virginia facility and have recently invested in equipment in our European facilities. Notwithstanding these plans and investments, we may not be able to expand our production capacity quickly enough in response to changing market conditions, and there can be no assurance that our production capacity will be able to meet our obligations and the growing market demand for our products. If we are unable to adequately expand our production capacity, we may be unable to take advantage of improved market conditions and increased demand for our products. We may also experience loss of market share, operational difficulties, increased costs, penalties for late delivery, reduction in demand for our products, and our reputation with our customers may be harmed, resulting in loss of business and a negative impact on our financial performance.

We are subject to unplanned business interruptions that may materially adversely affect our business.

Our operations may be materially adversely affected by unplanned events such as explosions, fires, war or terrorism, inclement weather, accidents, equipment, information technology systems and process failures, electrical blackouts or outages, transportation interruptions and supply interruptions. Operational interruptions at one or more of our production facilities could cause substantial losses and delays in our production capacity or increase our operating costs. In addition, replacement of assets damaged by such events could be difficult or expensive, and to the extent these losses are not covered by insurance or our insurance policies have significant deductibles, our financial position, results of operations and cash flows may be materially adversely affected by such events. For example, in 2008, a stretcher at Constellium’s Ravenswood, West Virginia facility was damaged due to a defect in its hydraulic system, causing a substantial outage at that facility that had a material impact on our production volumes at this facility and on our financial results for the affected period. In September 2015, Constellium’s Neuf-Brisach plant suffered an unplanned outage at the manufacturing facility as a result of the breakdown of a scalper. The outage had an adverse impact on the earnings for the third quarter of 2015.

Furthermore, because customers may be dependent on planned deliveries from us, customers that have to reschedule their own production due to our delivery delays may be able to pursue financial claims against us, and we may incur costs to correct such problems in addition to any liability resulting from such claims. Interruptions may also harm our reputation among actual and potential customers, potentially resulting in a loss of business.

If we were to lose order volumes from any of our largest customers, our sales volumes, revenues and cash flows would be reduced.

Our business is exposed to risks related to customer concentration. Our ten largest customers accounted for approximately 52% of our consolidated revenues for the year ended December 31, 2015, two of which accounted for more than 10% of our consolidated revenues over the same period. A significant downturn in the business or financial condition of our significant customers exposes us to the risk of default on contractual agreements and trade receivables, and this risk is increased by weak and deteriorating economic conditions on a global, regional or industry sector level.

If we fail to successfully renew, renegotiate or re-price our long-term agreements or related arrangements with our largest customers, our results of operations, financial condition and cash flows could be materially adversely affected.

We have long-term contracts and related arrangements with a significant number of our customers, some of which are subject to renewal, renegotiation or re-pricing at periodic intervals or upon changes in competitive and regulatory supply conditions. They also provide certain termination rights to our customers. Our failure to successfully renew, renegotiate or re-price such agreements, at all or on terms as favorable as our existing contracts and arrangements, or a material deterioration in or termination of these customer relationships, could result in a reduction or loss in customer purchase volume or revenue, and if we are not successful in replacing business lost from such customers, our results of operations, financial condition and cash flows could be materially adversely affected.

-12-

Table of Contents

In addition, our strategy of having dedicated facilities and arrangements with customers subjects us to the inherent risk of increased dependence on a single or a few customers with respect to these facilities. In such cases, the loss of such a customer, or the reduction of that customer’s business at one or more of our facilities, could negatively affect our financial condition and results of operations, and we may be unable to timely replace, or replace at all, lost order volumes and revenue.

The price volatility of energy costs may adversely affect our profitability.

Our operations use natural gas and electricity, which represent the third largest component of our cost of sales, after metal and labor costs. We purchase part of our natural gas and electricity on a spot-market basis. The volatility in costs of fuel, principally natural gas, and other utility services, principally electricity, used by our production facilities affects operating costs. Fuel and utility prices have been, and will continue to be, affected by factors outside our control, such as supply and demand for fuel and utility services in both local and regional markets as well as governmental regulation and imposition of further taxes on energy. Although we have secured some of our natural gas and electricity under fixed price commitments or long-term contracts with suppliers, future increases in fuel and utility prices, or disruptions in energy supply, may have an adverse effect on our financial position, results of operations and cash flows.

Regulations regarding carbon dioxide emissions, and unfavorable allocation of rights to emit carbon dioxide or other air emission-related issues, as well as other environmental laws and regulations, could have a material adverse effect on our business, financial condition and results of operations.

Many scientists, legislators and others attribute climate change to increased levels of greenhouse gases, including carbon dioxide, which has led to significant legislative and regulatory efforts to limit greenhouse gas emissions. Measures to reduce carbon dioxide and other greenhouse gas emissions that could directly or indirectly affect us or our suppliers are currently being developed or may be developed in the future. Substantial quantities of greenhouse gases are released as a consequence of our operations. Compliance with regulations governing such emissions tend to become more stringent over time and could lead to a need for us to further reduce such greenhouse gas emissions, to purchase rights to emit from third parties, or to make other changes to our business, all of which could result in significant additional costs or could reduce demand for our products. In addition, we are a significant purchaser of energy. Existing and future regulations relating to the emission of carbon dioxide by our energy suppliers could result in materially increased energy costs for our operations, and we may be unable to pass along these increased energy costs to our customers, which could have a material adverse effect on our business, financial condition and results of operations. For example, a revised European emissions trading system or a successor to the Kyoto Protocol under the United Nations Framework Convention on Climate Change, could have a material adverse effect on our business, financial condition and results of operations.

Our fabrication process is subject to regulations that may hinder our ability to manufacture our products. Some of the chemicals we use on our fabrication processes are subject to government regulation, such as REACH (“Registration, Evaluation, Authorisation, and Restriction of Chemicals”) in the EU. Under REACH, we are required to register some of our products with the European Chemicals Agency, and this process could cause significant delays or costs. If we fail to comply with these or similar laws and regulations, we may be required to make significant expenditures to reformulate the chemicals that we use in our products and materials or incur costs to register such chemicals to gain and/or regain compliance, and we may lose customers or revenue as a result. Additionally, we could be subject to significant fines or other civil and criminal penalties should we not achieve such compliance. To the extent that other nations in which we operate also require chemical registration, potential delays similar to those in Europe may delay our entry into these markets. Any failure to obtain or delay in obtaining regulatory approvals for chemical products used in our facilities could have a material adverse effect on our business, financial condition and results of operations.

We may not be able to successfully develop and implement new technology initiatives and other strategic investments in a timely manner.

We have invested in, and are involved with, a number of technology and process initiatives, including the development of new aluminium-lithium products. Being at the forefront of technological development is important to remain competitive. Several technical aspects of certain of these initiatives are still unproven and/or the eventual commercial outcomes and feasibility cannot be assessed with any certainty. Even if we are successful with these initiatives, we may not be able to bring them to market as planned before our competitors or at all, and the initiatives may end up costing more than expected. As a result, the costs and benefits from our investments in new technologies and the impact on our financial results may vary from present expectations.

In addition, we have undertaken and may continue to undertake growth, streamlining and productivity initiatives to improve performance. For example, we anticipate additional investments in the U.S. to increase our current hot mill capacity and build dedicated BiW finishing capacity. We cannot assure you that these initiatives will be completed or that they will have their intended benefits. Capital investments in debottlenecking or other organic growth initiatives may not produce the returns we anticipate. Even if we are able to generate new efficiencies successfully in the short- to medium-term, we may not be able to continue to reduce cost and increase productivity over the long term.

Our business requires substantial capital investments that we may be unable to fulfill. We may be unable to timely complete our expected capital investments, including in BiW, or may be unable to achieve the anticipated benefits of such investments.

Our operations are capital intensive. Our total capital expenditures were €350 million for the year ended December 31, 2015 and €199 million and €144 million for the years ended December 31, 2014 and 2013, respectively. We further anticipate remaining capital investments requirements to total approximately €1,480 million in the years ending December 31, 2016 to 2021, in the aggregate. Investments in Wise and in our Joint Venture with UACJ, after giving effect to the contemplated transaction with UACJ, including both maintenance and growth investments are expected to aggregate to approximately €345 million and €193 million respectively in the years ending December 31, 2016 to 2021. After giving effect to the transaction contemplated with UACJ, investments in our BiW Expansion program are expected to be approximately €284 million in the years ending December 31, 2016 to 2021, in the aggregate. See “Item 4. Information on the Company—B. Business Overview—Recent Developments—Expansion of Joint Venture with UACJ.”

There can be no assurance that we will be able to complete our capital investments, including our expected investments in BiW, on schedule, or that we will be able to achieve the anticipated benefits of such capital investments. In addition, we are under no legal obligation to complete the BiW Expansion program. We may at any time determine not to complete the BiW Expansion program. Additionally, we may not generate sufficient operating cash flows and our external financing sources may not be available in an amount sufficient to enable us to make anticipated capital expenditures (including completing our expected BiW investments), service or refinance our indebtedness or fund other liquidity needs.

If we are unable to make upgrades or purchase new plants and equipment, our financial condition and results of operations could be materially adversely affected by higher maintenance costs, lower sales volumes due to the impact of reduced product quality, and other competitive factors. If we are unable or determine not to complete our expected BiW investments, or such investments are delayed, we will not realize the anticipated benefits of such investments, which may adversely affect our results of operations.

Our planned joint investment with UACJ in BiW sheet in the U.S. may not be consummated, or may be consummated on terms that differ materially from those currently contemplated by the UACJ Term Sheet. We may be unable to execute on our strategy with respect to the joint venture with UACJ.

On March 10, 2016, Constellium announced that it had executed the UACJ Term Sheet with UACJ to expand the parties’ joint venture to produce automotive BiW sheet in the U.S. and establish a leadership position

-14-

Table of Contents

in the growing North American BiW market. Under the expanded joint venture, Constellium and UACJ contemplate a joint investment in two previously announced 100 kt finishing lines, which would be funded 51% by Constellium and 49% by Tri-Arrows Aluminium Holdings, a U.S. affiliate of UACJ. We currently expect the expanded joint venture, along with savings on upstream cost optimization, to reduce Constellium’s estimated capital requirement in North America to approximately $340 million through 2021 ($312 million or €284 million in the years ended December 31, 2016 to 2021), compared to the $620 million previously announced in October 2015 and $750 million announced in October 2014. See “Item 4. Information on the Company—B. Business Overview—Recent Developments—Expansion of Joint Venture with UACJ.”

Pursuant to the terms of the UACJ Term Sheet, the joint investment is subject to board approval by each party and the negotiation and execution of definitive documentation. If the board of directors of either Constellium or UACJ does not approve the joint investment contemplated by the UACJ Term Sheet, or if Constellium and UACJ do not reach agreement on and execute definitive documents in respect of the joint investment, then Constellium will not obtain the anticipated benefits of the joint investments, including the reduction in Constellium’s estimated capital requirement to fund its BiW investments in the U.S. Any definitive documents executed pursuant to the UACJ Term Sheet may have terms that differ materially from those currently contemplated.

In addition, we cannot assure you that we will be able to successfully implement the planned expansion or our business strategy with respect to our joint venture with UACJ. Any inability to execute on the expansion or our strategy with respect to the joint venture could inhibit or materially reduce our expected reduction in capital expenditures and could adversely affect our operations overall.

As part of our ongoing evaluation of our operations, we may undertake additional restructuring efforts in the future which could in some instances result in significant severance-related costs and other restructuring charges.

We recorded restructuring charges of €8 million for the year ended December 31, 2015, €12 million for the year ended December 31, 2014, and €8 million for the year ended December 31, 2013. Restructuring costs in 2015, 2014 and 2013 were primarily related to corporate and other sites restructuring operations. We may pursue additional restructuring activities in the future, which could result in significant severance-related costs, restructuring charges and related costs and expenses, including resulting labor disputes, which could materially adversely affect our profitability and cash flows.

A deterioration in our financial position or a downgrade of our ratings by a credit rating agency could increase our borrowing costs, lead to our inability to access liquidity facilities, and adversely affect our business relationships.

A deterioration in our financial position or a downgrade of our credit ratings could adversely affect our financing, limit access to the capital or credit markets or our liquidity facilities, or otherwise adversely affect the availability of other new financing on favorable terms, or at all, result in more restrictive covenants in agreements governing the terms of any future indebtedness that we incur, increase our borrowing costs, or otherwise impair our business, financial condition and results of operations.

While the terms of our other existing financing arrangements do not require us to maintain a specific credit rating, the commitments of Hitachi Capital America Corp. (the “New Wise RPA Purchaser”) under the New Wise Receivables Purchase Agreement (the “New Wise RPA”) are conditioned on, among other things, (i) Constellium’s corporate credit rating not having been withdrawn by either Standard & Poor’s or Moody’s or downgraded below B- by Standard & Poor’s and B3 by Moody’s, and (ii) there not having occurred a material adverse change in the business condition, operations, or performance of Wise Alloys Funding II LLC (the “New Wise RPA Seller”), Wise Alloys LLC, or Constellium Holdco II B.V. If Constellium’s corporate credit rating is withdrawn by either Standard & Poor’s or Moody’s or downgraded below B- by Standard & Poor’s and B3 by

-15-

Table of Contents

Moody’s, or a material adverse change occurs in the business condition, operations or performance of the New Wise RPA Seller, Wise Alloys LLC, or the Constellium Holdco II B.V., a condition precedent to the obligation of the New Wise RPA Purchaser under the New Wise RPA to purchase receivables from the New Wise RPA Seller will not be satisfied, and all purchases under the New Wise RPA will become uncommitted. If the New Wise RPA is not extended, refinanced or replaced, Wise’s cash collections from customers will be on longer terms than currently funded through the New Wise RPA. As a result, Wise’s liquidity could meaningfully decrease, causing Wise to have insufficient liquidity to operate its business and service its indebtedness, unless another source of liquidity, which may include capital contributions from the ultimate parent Constellium N.V., is identified. See “Item 10. Additional Information—C. Material Contracts—Wise Factoring Facilities” and “Item 3. Key Information—D. Risk Factors—Wise has substantial leverage and may be unable to obtain sufficient liquidity to operate its business and service its indebtedness. Constellium may elect to make capital contributions to Wise but is under no legal obligation to do so.”

A deterioration of our financial position or a further downgrade of our credit ratings for any reason could also increase our borrowing costs and have an adverse effect on our business relationships with customers, suppliers and hedging counterparties. As discussed above, we enter into various forms of hedging arrangements against currency, interest rate or metal price fluctuations and trade metal contracts on the LME. Financial strength and credit ratings are important to the availability and pricing of these hedging and trading activities. As a result, any downgrade of our credit ratings may make it more costly for us to engage in these activities, and changes to our level of indebtedness may make it more difficult or costly for us to engage in hedging and trading activities in the future.

Our indebtedness could materially adversely affect our ability to invest in or fund our operations, limit our ability to react to changes in the economy or our industry or force us to take alternative measures.

Our indebtedness impacts our flexibility in operating our business and could have important consequences for our business and operations, including the following: (i) it may make us more vulnerable to downturns in our business or the economy; (ii) a substantial portion of our cash flows from operations will be dedicated to the repayment of our indebtedness and will not be available for other purposes; (iii) it may restrict us from making strategic acquisitions, introducing new technologies or exploiting business opportunities; and (iv) it may adversely affect the terms under which suppliers provide goods and services to us. Our indebtedness has materially increased as a result of the Wise Acquisition. By increasing our indebtedness, we have made ourselves more susceptible to the risks discussed above.

If we are unable to meet our debt service obligations, including our obligations under the May 2014 Notes, the December 2014 Notes, the Senior Secured Notes issued on March 30, 2016, and the Wise Notes, and pay our expenses, we may be forced to reduce or delay business activities and capital expenditures (including, without limitation, our expected investments in BiW), sell assets, obtain additional debt or equity capital, restructure or refinance all or a portion of our debt before maturity or take other measures. Such measures may materially adversely affect our business. If these alternative measures are unsuccessful, we could default on our obligations, which could result in the acceleration of our outstanding debt obligations and could have a material adverse effect on our business, results of operations and financial condition.

The terms of our indebtedness contain covenants that restrict our current and future operations, and a failure by us to comply with those covenants may materially adversely affect our business, results of operations and financial condition.

Our indebtedness contains, and any future indebtedness we may incur would likely contain, a number of restrictive covenants that will impose significant operating and financial restrictions on our ability to, among other things: (i) incur or guarantee additional debt; (ii) pay dividends and make other restricted payments and investments (including investments in and guarantees of certain indebtedness of Wise); (iii) create or incur certain liens; (iv) make certain loans, acquisitions or investments; (v) engage in sales of assets and subsidiary stock; (vi) enter into transactions with affiliates (including transactions between the Company and its subsidiaries

-16-

Table of Contents

(other than Wise), on the one hand, and Wise, on the other, that are not at least as favorable to Wise as would be obtained in an arm’s-length transaction); (vii) transfer all or substantially all of our assets or enter into merger or consolidation transactions; and (viii) enter into sale and lease-back transactions.

In addition, the Wise ABL Facility provides that if borrowing availability thereunder drops below a threshold amount equal to the greater of (a) 10% of the aggregate commitments under the Wise ABL Facility and (b) $20 million, Wise Alloys LLC will be required to maintain a minimum fixed charge coverage ratio of 1.0 to 1.0, calculated on a trailing twelve month basis until such time as borrowing availability has been at least equal to the greater of $20 million and 10% of the aggregate commitments under the Wise ABL Facility for thirty consecutive days.

A failure to comply with our debt covenants could result in an event of default that, if not cured or waived, could have a material adverse effect on our business, results of operations and financial condition. If we default under our indebtedness, we may not be able to borrow additional amounts and our lenders could elect to declare all outstanding borrowings, together with accrued and unpaid interest and fees, to be due and payable, or take other remedial actions. Our indebtedness also contains cross-default provisions, which means that if an event of default occurs under certain material indebtedness, such event of default may trigger an event of default under our other indebtedness. If our indebtedness were to be accelerated, we cannot assure you that our assets would be sufficient to repay such indebtedness in full and our lenders could foreclose on our pledged assets. See “Item 10. Additional Information—C. Material Contracts.”

Our existing, and any future, variable rate indebtedness subjects us to interest rate risk, which could cause our annual debt service obligations to increase significantly.

A portion of our indebtedness is, and our future indebtedness may be, subject to variable rates of interest, exposing us to interest rate risk. See “Item 10. Additional Information—C. Material Contracts.” If interest rates increase, our debt service obligations on the variable rate indebtedness would increase, resulting in a reduction of our net income that could be significant, even though the principal amount borrowed would remain the same.

We could be required to make unexpected contributions to our defined benefit pension plans as a result of adverse changes in interest rates and the capital markets.

Most of our pension obligations relate to funded defined benefit pension plans for our employees in the United States and Switzerland, unfunded pension benefits in France and Germany, and lump sum indemnities payable to our employees in France and Germany upon retirement or termination. Our pension plan assets consist primarily of funds invested in listed stocks and bonds. Our estimates of liabilities and expenses for pensions and other post-retirement benefits incorporate a number of assumptions, including interest rates used to discount future benefits. Our results of operations, liquidity or shareholders’ equity in a particular period could be materially adversely affected by capital market returns that are less than their assumed long-term rate of return or a decline in the rate used to discount future benefits. If the assets of our pension plans do not achieve assumed investment returns for any period, such deficiency could result in one or more charges against our earnings for that period. In addition, changing economic conditions, poor pension investment returns or other factors may require us to make unexpected cash contributions to the pension plans in the future, preventing the use of such cash for other purposes.

In addition, Wise provides benefits under a defined benefit pension plan that was frozen in 2007. Declines in interest rates or the value of pension assets or certain other changes could affect the level and timing of required contributions to the pension plan in the future. If future contributions are insufficient to fund the pension plan adequately to cover Wise’s future pension obligations, we could incur cash expenditures and costs materially higher than anticipated. Wise’s pension obligation is calculated annually and is based on several assumptions, including then prevailing conditions, which may change from year to year. In any year, if these assumptions are inaccurate, we could be required to expend greater amounts than anticipated.

Wise also participates in various “multi-employer” pension plans administered by labor unions representing some of its employees. Wise’s withdrawal liability for any multi-employer plan would depend on the extent of the plan’s funding of vested benefits. In the ordinary course of Wise’s renegotiation of collective bargaining agreements with labor unions that maintain these plans, Wise could decide to discontinue participation in a plan, and in that event Wise could face a withdrawal liability. Wise could also be treated as withdrawing from participation in one of these plans if the number of its employees participating in these plans is reduced to a certain degree over certain periods of time. Such reductions in the number of Wise’s employees participating in these plans could occur as a result of changes in Wise’s business operations, such as facility closures or consolidations. Any withdrawal liability could have an adverse effect on our results of operations.

A substantial percentage of our workforce is unionized or covered by collective bargaining agreements that may not be successfully renegotiated.

A significant number of our employees are represented by unions or equivalent bodies or are covered by collective bargaining or similar agreements that are subject to periodic renegotiation. Although we believe that we will be able to successfully negotiate new collective bargaining agreements when the current agreements expire, these negotiations may not prove successful, and may result in a significant increase in the cost of labor, or may break down and result in the disruption or cessation of our operations.

The loss of certain members of our management team may have a material adverse effect on our operating results.

Our success will depend, in part, on the efforts of our senior management and other key employees. These individuals possess sales, marketing, engineering, technical, manufacturing, financial and administrative skills that are critical to the operation of our business. If we lose or suffer an extended interruption in the services of one or more of our senior officers or other key employees, our ability to operate and expand our business, improve our operations, develop new products, and, as a result, our financial condition and results of operations, may be negatively affected. Moreover, the hiring of qualified individuals is highly competitive in our industry, and we may not be able to attract and retain qualified personnel to replace or succeed members of our senior management or other key employees.

As a result of the Wise Acquisition, we may not be able to retain key personnel or recruit additional qualified personnel and may experience disruptions and uncertainty surrounding our relationships with existing and future customers and suppliers.

We are highly dependent on the continuing efforts of our senior management team and other key personnel. As a result of the Wise Acquisition, our current and prospective employees, including Wise employees, could experience uncertainty about their future roles and relationships with Constellium and Wise. This uncertainty may adversely affect our ability to attract and retain current and prospective key management, sales, marketing and technical personnel, and may cause disruptions in our relationships with existing and future customers and suppliers. Any failure to attract and retain key personnel, including Wise employees, or disruption in our relationships with customers and suppliers, including customers and suppliers of Wise, could have a material adverse effect on our business. We do not maintain “key person” insurance covering any member of our management team.

The consummation of the Wise Acquisition could also cause disruptions in and create uncertainty surrounding our and Wise’s relationships with existing and future customers and suppliers. Such customers and suppliers may, in response to the consummation of the Wise Acquisition, delay or defer contracting decisions, or may not remain as customers and suppliers following the completion of the Wise Acquisition. Change of control provisions in certain of Wise’s contracts may have given customers the right to terminate or change the terms of those contracts as a result of the Wise Acquisition. The loss of significant customers or suppliers could have a material and adverse effect on our business prospects, results of operations and financial condition.

If we are unable to successfully transition to new leadership following the expected retirement of our current Chief Executive Officer, our business and operating results could be adversely affected.

Our Chief Executive Officer, Pierre Vareille, has informed the Company’s Board of Directors of his desire to retire during the course of 2016. At the request of the Company’s Board of Directors, Mr. Vareille has agreed to remain in his current role of Chief Executive Officer until a successor is appointed, and to thereafter become an advisor to the Company’s Board of Directors to facilitate this leadership transition. While the Company has identified a particular candidate, no agreement has been reached. We are working to ensure a smooth transition but we cannot assure you when we will reach an agreement with a successor, what impact, if any, the transition may have on our business, and what effect, if any, a new Chief Executive Officer may have on our business and our ability to retain our senior executives and other key personnel. The loss of the services of such senior executives or key personnel or any general instability in the composition of our senior management team could have a negative impact on our ability to execute our business and operating strategies and may adversely affect our operating results. Once we hire a new Chief Executive Officer, our financial and operational success will be dependent in large part on the new executive’s ability to gain proficiency in leading our company, implement or adapt our corporate strategies and initiatives and develop key professional relationships, including relationships with our team members, our key customers and suppliers and other business partners.

We could experience labor disputes and work stoppages that could disrupt our business and have a negative impact on our financial condition and results of operations.

From time to time, we may experience labor disputes and work stoppages at our facilities. For example, we experienced work stoppages and labor disturbances at our Ravenswood, West Virginia facility in 2012 in conjunction with the renegotiation of the collective bargaining agreement. Additionally, we experienced work stoppages and labor disturbances at our Issoire and Neuf-Brisach facilities in November 2013 and resumed normal operations in early December 2013. We also faced minor stoppages in our Issoire site in December 2015 during the yearly Collective Bargaining Agreement negotiations. Existing collective bargaining agreements may not prevent a strike or work stoppage at our facilities in the future. Any such stoppages or disturbances may have a negative impact on our financial condition and results of operations by limiting plant production, sales volumes, profitability and operating costs.

In addition, in light of demographic trends in the labor markets where we operate, we expect that our factories will be confronted with high levels of natural attrition in the coming years due to retirements. Strategic workforce planning will be a challenge to ensure a controlled exit of skills and competencies and the timely acquisition of new talent and competencies, in line with changing technological and industrial needs.

If we do not adequately maintain and continue to evolve our financial reporting and internal controls (which could result in higher operating costs), we may be unable to accurately report our financial results or prevent fraud.

We will need to continue to improve existing, and implement new, financial reporting and management systems, procedures and controls to manage our business effectively and support our growth in the future, especially because we lack a long history of operations as a standalone entity. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures and controls, or the obsolescence of existing financial control systems, could harm our ability to accurately forecast sales demand and record and report financial and management information on a timely and accurate basis.

We could also suffer a loss of confidence in the reliability of our financial statements if our independent registered public accounting firm reports a material weakness in our internal controls, if we do not develop and maintain effective controls and procedures or if we are otherwise unable to deliver timely and reliable financial information. Any loss of confidence in the reliability of our financial statements or other negative reaction to our failure to develop timely or adequate disclosure controls and procedures or internal controls could result in a

-19-

Table of Contents

decline in the trading price of our ordinary shares. In addition, if we fail to remedy any material weakness, our financial statements may be inaccurate, we may face restricted access to the capital markets and the price of our ordinary shares may be materially adversely affected.

We may not be able to adequately protect proprietary rights to our technology.

Our success depends in part upon our proprietary technology and processes. We believe that our intellectual property has significant value and is important to the marketing of our products and maintaining our competitive advantage. Although we attempt to protect our intellectual property rights both in the United States and in foreign countries through a combination of patent, trademark, trade secret and copyright laws, as well as through confidentiality and nondisclosure agreements and other measures, these measures may not be adequate to fully protect our rights. For example, we have a presence in China, which historically has afforded less protection to intellectual property rights than the United States. Our failure to obtain or maintain adequate protection of our intellectual property rights for any reason could have a material adverse effect on our business, results of operations and financial condition.

We have applied for patent protection relating to certain existing and proposed products and processes. While we generally apply for patents in those countries where we intend to make, have made, use or sell patented products, we may not accurately predict all of the countries where patent protection will ultimately be desirable. If we fail to timely file a patent application in any such country, we may be precluded from doing so at a later date. Furthermore, we cannot assure you that any of our patent applications will be approved. We also cannot assure you that the patents issued as a result of our foreign patent applications will have the same scope of coverage as our United States patents. The patents we own could be challenged, invalidated or circumvented by others and may not be of sufficient scope or strength to provide us with any meaningful protection or commercial advantage. Further, we cannot assure you that competitors or other third parties will not infringe our patents, or that we will have adequate resources to enforce our patents.

We also rely on unpatented proprietary technology. It is possible that others will independently develop the same or similar technology or otherwise obtain access to our unpatented technology. To protect our trade secrets and other proprietary information, we require employees, consultants, advisors and collaborators to enter into confidentiality agreements. We cannot assure you that these agreements will provide meaningful protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use, misappropriation or disclosure of such trade secrets, know-how or other proprietary information. If we are unable to maintain the proprietary nature of our technologies, we could be materially adversely affected.

We rely on our trademarks, trade names and brand names to distinguish our products from the products of our competitors, and have registered or applied to register many of these trademarks. We cannot assure you that our trademark applications will be approved. Third parties may also oppose our trademark applications, or otherwise challenge our use of the trademarks. In the event that our trademarks are successfully challenged, we could be forced to rebrand our products, which could result in loss of brand recognition, and could require us to devote resources to advertising and marketing new brands. Further, we cannot assure you that competitors or other third parties will not infringe our trademarks, or that we will have adequate resources to enforce our trademarks.

We may institute or be named as a defendant in litigation regarding our intellectual property and such litigation may be costly and divert management’s attention and resources.

Any attempts to enforce our intellectual property rights, even if successful, could result in costly and prolonged litigation, divert management’s attention and resources, and materially adversely affect our results of operations and cash flows. The unauthorized use of our intellectual property may adversely affect our results of operations as our competitors would be able to utilize such property without having had to incur the costs of developing it, thus potentially reducing our relative profitability.

-20-

Table of Contents

Furthermore, we may be subject to claims that we have infringed the intellectual property rights of another. Even if without merit, such claims could result in costly and prolonged litigation, cause us to cease making, licensing or using products or technologies that incorporate the challenged intellectual property, require us to redesign, reengineer or rebrand our products, if feasible, divert management’s attention and resources, and materially adversely affect our results of operations and cash flows. We may also be required to enter into licensing agreements in order to continue using technology that is important to our business, or we may be unable to obtain license agreements on acceptable terms, either of which could negatively affect our financial position, results of operations and cash flows.

Interruptions in or failures of our information systems, or failure to protect our information systems against cyber-attacks or information security breaches, could have a material adverse effect on our business.

The efficient operation of our business depends on our information technology systems. We rely on our information technology systems to effectively manage our business, data, accounting, financial reporting, communications, supply chain, order entry and fulfillment and other business processes. The failure of our information technology systems to perform as we anticipate could disrupt our business and could result in transaction errors, processing inefficiencies, and the loss of sales and customers, causing our business and results of operations to suffer.

Some of our information systems are nearing obsolescence, in that the software versions they are developed on are no longer fully supported or kept up-to-date by the original vendors. Whilst the correct day-to-day operations are not at risk, major new requirements (e.g., in legal or payroll) might require manual workarounds if the current software versions do not support those new functionalities.

Information security risks have generally increased in recent years because of the proliferation of new technologies and the increased sophistication and activities of perpetrators of cyber-attacks. A failure in or breach of our information systems as a result of cyber-attacks or information security breaches could disrupt our business, result in the disclosure or misuse of confidential or proprietary information, damage our reputation, increase our costs or cause losses. As cyber threats continue to evolve, we may be required to expend additional resources to continue to enhance our information security measures or to investigate and remediate any information security vulnerabilities.

Current liabilities under, as well as the cost of compliance with, environmental, health and safety laws could increase our operating costs and negatively affect our financial condition and results of operations.

Our operations are subject to federal, state and local laws and regulations in the jurisdictions where we do business, which govern, among other things, air emissions, wastewater discharges, the handling, storage and disposal of hazardous substances and wastes, the remediation of contaminated sites, and employee health and safety. At December 31, 2015, we had close-down and environmental restoration costs provisions of €88 million. Future environmental regulations or more aggressive enforcement of existing regulations could impose stricter compliance requirements on us and on the industries in which we operate. Additional pollution control equipment, process changes, or other environmental control measures may be needed at some of our facilities to meet future requirements. If we are unable to comply with these laws and regulations, we could incur substantial costs, including fines and civil or criminal sanctions, or costs associated with upgrades to our facilities or changes in our manufacturing processes in order to achieve and maintain compliance. Additionally, evolving regulatory standards and expectations can result in increased litigation and/or increased costs. There are also no assurances that newly discovered conditions, or new or more aggressive enforcement of applicable environmental requirements, or any failure by counterparties to perform indemnification obligations, will not have a material adverse effect on our business.

Financial responsibility for contaminated property can be imposed on us where current operations have had an environmental impact. Such liability can include the cost of investigating and remediating contaminated soil

-21-

Table of Contents

or ground water, financial assurance, fines and penalties sought by environmental authorities, and damages arising out of personal injury, contaminated property and other toxic tort claims, as well as lost or impaired natural resources. Certain environmental laws impose strict, and in certain circumstances joint and several, liability for certain kinds of matters, such that a person can be held liable without regard to fault for all of the costs of a matter regardless of legality at the time of conduct and even though others were also involved or responsible.

Wise is subject to or party to certain environmental claims and matters and there can be no assurances that those matters will be resolved favorably or that such matters will not adversely affect our business, financial condition and results of operations.

We have accrued, and expect to accrue, costs relating to the above matters that are reasonably expected to be incurred based on available information. However, it is possible that actual costs may differ, perhaps significantly, from the amounts expected or accrued. Similarly, the timing of those expenditures may occur faster than anticipated. These differences could negatively affect our financial position, results of operations and cash flows.

Other legal proceedings or investigations, or changes in applicable laws and regulations, could increase our operating costs and negatively affect our financial condition and results of operations.

We may from time-to-time be involved in, or be the subject of, disputes, proceedings and investigations with respect to a variety of matters, including matters related to personal injury, intellectual property, employees, taxes, contracts, anti-competitive or anti-corruption practices as well as other disputes and proceedings that arise in the ordinary course of business. It could be costly to address these claims or any investigations involving them, whether meritorious or not, and legal proceedings and investigations could divert management’s attention as well as operational resources, negatively affecting our financial position, results of operations and cash flows. Additionally, as with the environmental laws and regulations, other laws and regulations which govern our business are subject to change at any time. Compliance with changes to existing laws and regulations could have a material adverse effect on our financial position, results of operations and cash flows.

Product liability claims against us could result in significant costs and could materially adversely affect our reputation and our business.

If any of the products that we sell are defective or cause harm to any of our customers, we could be exposed to product liability lawsuits and/or warranty claims. If we were found liable under product liability claims or are obligated under warranty claims, we could be required to pay substantial monetary damages. Even if we successfully defend ourselves against these types of claims, we could still be forced to spend a substantial amount of money in litigation expenses, our management could be required to devote significant time and attention to defending against these claims, and our reputation could suffer, any of which could harm our business.

Our operations present significant risk of injury or death.

Because of the heavy industrial activities conducted at our facilities, there exists a risk of injury or death to our employees or other visitors, notwithstanding the safety precautions we take. Our operations are subject to regulation by national, state and local agencies responsible for employee health and safety, which has from time to time levied fines against us for certain isolated incidents. While such fines have not been material and we have in place policies to minimize such risks, we may nevertheless be unable to avoid material liabilities for any employee death or injury that may occur in the future, and any such incidents may materially adversely impact our reputation.

The insurance level that we maintain may not fully cover all potential exposures.

We maintain property, casualty and workers’ compensation insurance, but such insurance does not cover all risks associated with the hazards of our business and is subject to limitations, including deductibles and maximum liabilities covered. We may incur losses beyond the limits, or outside the coverage, of our insurance policies, including, but not limited to, liabilities for breach of contract, environmental compliance or remediation. In addition, from time to time, various types of insurance for companies in our industries have not been available on commercially acceptable terms or, in some cases, have not been available at all. In the future, we may not be able to obtain coverage at current levels, and our premiums may increase significantly on coverage that we maintain.

Increases in our effective tax rate, changes in income tax laws, additional income tax liabilities due to unfavorable resolution of tax audits and challenges to our tax position could have a material adverse impact on our financial results.

We operate in multiple tax jurisdictions and pay tax on our income according to the tax laws and regulations of these jurisdictions. Various factors, some of which are beyond our control, determine our effective tax rate and/or the amount we are required to pay, including changes in or interpretations of tax laws and regulations in any given jurisdiction or global- and EU-based initiatives such as the Action Plan on Base Erosion and Profit Shifting (“BEPS”) of the Organization for Economic Co-operation and Development and the proposed EU anti-BEPS Directive which aim among other things to address tax avoidance by multinational companies, our ability to use net operating loss and tax credit carry forwards and other tax attributes, changes in geographical allocation of income and expense, and our judgment about the realizability of deferred tax assets. Such changes to our effective tax rate could materially adversely affect our financial position, liquidity, results of operations and cash flows.

In addition, due to the size and nature of our business, we are subject to ongoing reviews by taxing jurisdictions on various tax matters, including challenges to positions we assert on our income tax and withholding tax returns. We accrue income tax liabilities and tax contingencies based upon our best estimate of the taxes ultimately expected to be paid after considering our knowledge of all relevant facts and circumstances, existing tax laws and regulations, our experience with previous audits and settlements, the status of current tax examinations and how the tax authorities and courts view certain issues. Such amounts are included in income taxes payable, other non-current liabilities or deferred income tax liabilities, as appropriate, and updated over time as more information becomes available. We record additional tax expense in the period in which we determine that the recorded tax liability is less than the ultimate assessment we expect. We are currently subject to audit and review in a number of jurisdictions in which we operate, and further audits may commence in the future.

The Company is incorporated under the laws of the Netherlands and on this basis is subject to Dutch tax laws as a Dutch resident taxpayer. We believe that, because of the manner in which we conduct our business, the Company is resident solely in the Netherlands for tax purposes. However, if our tax position were successfully challenged by applicable tax authorities, or if there were changes in the tax laws, tax treaties, or the interpretation or application thereof (which could in certain circumstances have retroactive effect) or in the manner in which we conduct our business, this could materially adversely affect our financial position.

Our historical financial information presented in this report may not be representative of future results and our relatively short history operating as a standalone company may pose some challenges.

Due to inherent uncertainties of our business, the historical financial information does not necessarily indicate what our results of operations, financial position, cash flows or costs and expenses will be in the future as past performance is not necessarily an indicator of future performance. In addition, we have a relatively short history operating as a standalone company which may pose some operational challenges to our management. Our

-23-

Table of Contents

management team has faced and could continue to face operational and organizational challenges and costs related to operating as a standalone company, such as continuing to establish various corporate functions, formulating policies, preparing standalone financial statements and continued integration of the management team. These challenges may divert their attention from running our core business or otherwise materially adversely affect our operating results.

We are a foreign private issuer under the U.S. securities laws within the meaning of the New York Stock Exchange (“NYSE”) rules. As a result, we qualify for and rely on exemptions from certain corporate governance requirements and may rely on other exemptions available to us in the future.

As a “foreign private issuer,” as such term is defined in Rule 405 under the Securities Act, we are permitted to follow our home country practice in lieu of certain corporate governance requirements of the NYSE, including the NYSE requirements that (i) a majority of the board of directors consists of independent directors; (ii) the nominating and corporate governance committee be composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and (iii) the compensation committee be composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities. Foreign private issuers are also exempt from certain U.S. securities law requirements applicable to U.S. domestic issuers, including the requirement to file quarterly reports on Form 10-Q and to distribute a proxy statement pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”) Section 14 in connection with the solicitation of proxies for shareholder meetings.

We rely on the exemptions for foreign private issuers and follow Dutch corporate governance practices in lieu of some of the NYSE corporate governance rules specified above. We currently rely on exemptions from the requirements set out in (i), (ii) and (iii) above, but in the future, we may change what home country corporate governance practices we follow, and, accordingly, which exemptions we rely on from the NYSE requirements. So long as we qualify as a foreign private issuer, you may not have the same protections afforded to shareholders of companies that are subject to all of the NYSE corporate governance requirements.

We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses. If we were to lose our foreign private issuer status, the regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic issuer could be significantly more than costs we incur as a foreign private issuer.

If we were not a foreign private issuer, we would be required to file periodic reports and registration statements on U.S. domestic issuer forms with the SEC, including proxy statements pursuant to Section 14 of the Exchange Act. These SEC disclosure requirements are more detailed and extensive than the forms available to a foreign private issuer. In addition, our directors, officers and 10% owners would become subject to insider short-swing profit disclosure and recovery rules under Section 16 of the Exchange Act. We could also be required to modify certain of our policies to comply with corporate governance practices associated with U.S. domestic issuers. Such conversion and modifications would involve additional costs.

In addition, we would lose our ability to rely upon exemptions from certain NYSE corporate governance requirements that are available to foreign private issuers. In particular, within six months of losing our foreign private issuer status we would be required to have a majority of independent directors and a nominating/corporate governance committee and a compensation committee comprised entirely of independent directors, unless other exemptions are available under the NYSE rules. Any of these changes would likely increase our regulatory and compliance costs and expenses, which could have a material adverse effect on our business and financial results.

We do not comply with all the provisions of the Dutch Corporate Governance Code which could affect your rights as a shareholder.

We are subject to the Dutch Corporate Governance Code, which applies to all Dutch companies listed on a government-recognized stock exchange, whether in the Netherlands or elsewhere, including the NYSE and

-24-

Table of Contents

Euronext Paris. The Dutch Corporate Governance Code contains principles and best practice provisions for boards of directors, shareholders and general meetings of shareholders, financial reporting, auditors, disclosure, compliance and enforcement standards. The Dutch Corporate Governance Code is based on a “comply or explain” principle. Accordingly, companies are required to disclose in their annual reports, filed in the Netherlands, whether they comply with the provisions of the Dutch Corporate Governance Code and, if they do not comply with those provisions, to give the reasons for such noncompliance. The principles and best practice provisions apply to the board (relating to, among other matters, the board’s role and composition, conflicts of interest and independence requirements, board committees and remuneration), shareholders and the general meeting of shareholders (for example, regarding anti-takeover protection and obligations of a company to provide information to its shareholders), and financial reporting (such as external auditor and internal audit requirements). We have decided not to comply with a number of the provisions of the Dutch Corporate Governance Code because such provisions conflict, in whole or in part, with the corporate governance rules of NYSE and U.S. securities laws that apply to our company whose ordinary shares are traded on the NYSE, or because such provisions do not reflect best practices of global companies listed on the NYSE. This may affect your rights as a shareholder and you may not have the same level of protection as a shareholder in a Dutch company that fully complies with the Dutch Corporate Governance Code. See “Item 16G. Corporate Governance—Dutch Corporate Governance Code.”

The market price of our ordinary shares may fluctuate significantly, and you could lose all or part of your investment.

The market price of our ordinary shares may be influenced by many factors, some of which are beyond our control and could result in significant fluctuations, including: (i) the failure of financial analysts to cover our ordinary shares, changes in financial estimates by analysts or any failure by us to meet or exceed any of these estimates; (ii) actual or anticipated variations in our operating results; (iii) announcements by us or our competitors of significant contracts or acquisitions; (iv) the recruitment or departure of key personnel; (v) regulatory and litigation developments; (vi) developments in our industry; (vii) future sales of our ordinary shares; and (viii) investor perceptions of us and the industries in which we operate.

In addition, the stock market in general has experienced substantial price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of particular companies affected. These broad market and industry factors may materially harm the market price of our ordinary shares, regardless of our operating performance. In the past, following periods of volatility in the market price of certain companies’ securities, securities class action litigation has been instituted against these companies. If any such litigation is instituted against us, it could materially adversely affect our business, results of operations and financial condition.

Sales of substantial amounts of our ordinary shares in the public market, or the perception that these sales may occur, could cause the market price of our ordinary shares to decline.

Sales of substantial amounts of our ordinary shares in the public market, or the perception that these sales may occur, could cause the market price of our ordinary shares to decline. This could also impair our ability to raise additional capital through the sale of our equity securities. In addition, the sale of our ordinary shares by our officers and directors in the public market, or the perception that such sales may occur, could cause the market price of our ordinary shares to decline. Prior to the completion of our IPO, we amended our memorandum and articles of association (the “Amended and Restated Articles of Association”) to provide authorization to issue up to 398,500,000 Class A ordinary shares and 1,500,000 Class B ordinary shares. A total of 105,476,899 Class A ordinary shares are outstanding as of December 31, 2015. We may issue ordinary shares or other securities from time to time as consideration for, or to finance, future acquisitions and investments or for other capital needs. We cannot predict the size of future issuances of our shares or the effect, if any, that future sales and issuances of shares would have on the market price of our ordinary shares. If any such acquisition or investment is significant, the number of ordinary shares or the number or aggregate principal amount, as the case may be, of other

-25-

Table of Contents

securities that we may issue may in turn be substantial and may result in additional dilution to our shareholders. We may also grant registration rights covering ordinary shares or other securities that we may issue in connection with any such acquisitions and investments.

Any shareholder acquiring 30% or more of our voting rights may be required to make a mandatory takeover bid or be subject to voting restrictions.

Under Dutch law, if a party directly or indirectly acquires control of a Dutch company, all or part of whose shares are admitted to trading on a regulated market, that party may be required to make a public offer for all other shares of the company (mandatory takeover bid). “Control” is defined as the ability to exercise, whether or not in concert with others, at least 30% of the voting rights at a general meeting of shareholders. Controlling shareholders existing before an offering are generally exempt from this requirement, unless their controlling interest drops below 30% and then increases again to 30% or more. The purpose of this requirement is to protect the interests of minority shareholders. Any shareholder acquiring 30% or more of our voting rights may be limited in its ability to vote on our ordinary shares.

Provisions of our organizational documents and applicable law may impede or discourage a takeover, which could deprive our investors of the opportunity to receive a premium for their ordinary shares or to make changes in our board of directors.

Several provisions of our Amended and Restated Articles of Association and the laws of the Netherlands could make it difficult for our shareholders to change the composition of our board of directors, thereby preventing them from changing the composition of our management. In addition, the same provisions may discourage, delay or prevent a merger, consolidation or acquisition that shareholders may consider favorable. Provisions of our Amended and Restated Articles of Association impose various procedural and other requirements, which could make it more difficult for shareholders to effect certain corporate actions. These anti-takeover provisions could substantially impede the ability of our shareholders to benefit from a change in control and, as a result, may materially adversely affect the market price of our ordinary shares and your ability to realize any potential change of control premium.

Our general meeting of shareholders has empowered our board of directors to issue shares and restrict or exclude preemptive rights on those shares for a period of five years. Accordingly, an issue of new shares may make it more difficult for a shareholder to obtain control over our general meeting of shareholders.

In addition, because certain of our products may have applications in the defense sector, we may be subject to rules and regulations in France and other jurisdictions that could impede or discourage a takeover or other change in control of Constellium or its subsidiaries. In particular, Constellium supplies aluminium alloy products, such as plates, sheets, profiles, tubes and castings, and related services and R&D activities in connection with aerospace and defense programs in France. As a result, a controlling investment in Constellium or certain of its French subsidiaries, or the purchase of assets constituting a business that produces products or provides services with applications in the defense sector, by a company or individual that is considered to be foreign or non-resident in France may be subject to the French Monetary and Financial Code, which requires prior authorization of the French Ministry of Economy.

United States civil liabilities may not be enforceable against us.

We are incorporated under the laws of the Netherlands and substantial portions of our assets are located outside of the United States. In addition, certain directors, officers and experts named herein reside outside the United States. As a result, it may be difficult for investors to effect service of process within the United States upon us or such other persons residing outside the United States, or to enforce outside the United States judgments obtained against such persons in U.S. courts in any action, including actions predicated upon the civil liability provisions of the U.S. federal securities laws. In addition, it may be difficult for investors to enforce, in original actions brought in courts in jurisdictions located outside the United States, rights predicated upon the U.S. federal securities laws.

-26-

Table of Contents

There is no treaty between the United States and the Netherlands for the mutual recognition and enforcement of judgments (other than arbitration awards) in civil and commercial matters. Therefore, a final judgment for the payment of money rendered by any federal or state court in the United States based on civil liability, whether or not predicated solely upon the U.S. federal securities laws, would not be enforceable in the Netherlands unless the underlying claim is re-litigated before a Dutch court. However, under current practice, the courts of the Netherlands may be expected to render a judgment in accordance with the judgment of the relevant United States court, provided that such judgment (i) is a final judgment and has been rendered by a court which has established its jurisdiction on the basis of internationally accepted grounds of jurisdictions, (ii) has not been rendered in violation of elementary principles of fair trial, (iii) is not contrary to the public policy of the Netherlands, and (iv) is not incompatible with (a) a prior judgment of a Netherlands court rendered in a dispute between the same parties, or (b) a prior judgment of a foreign court rendered in a dispute between the same parties, concerning the same subject matter and based on the same cause of action, provided that such prior judgment is not capable of being recognized in the Netherlands. It is uncertain whether this practice extends to default judgments as well.

Based on the foregoing, there can be no assurance that U.S. investors will be able to enforce against us or members of our board of directors, officers or certain experts named herein who are residents of the Netherlands or countries other than the United States any judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities laws.

In addition, there is doubt as to whether a Dutch court would impose civil liability on us, the members of our board of directors, our officers or certain experts named herein in an original action predicated solely upon the U.S. federal securities laws brought in a court of competent jurisdiction in the Netherlands against us or such members, officers or experts, respectively.

The rights of our shareholders may be different from the rights of shareholders governed by the laws of U.S. jurisdictions.

Our corporate affairs are governed by our Amended and Restated Articles of Association and by the laws governing companies incorporated in the Netherlands. The rights of shareholders and the responsibilities of members of our board of directors may be different from the rights and obligations of shareholders in companies governed by the laws of U.S. jurisdictions. In the performance of its duties, our board of directors is required by Dutch law to consider the interests of our company, its shareholders, its employees and other stakeholders, in all cases with due observation of the principles of reasonableness and fairness. It is possible that some of these parties will have interests that are different from, or in addition to, your interests as a shareholder. See “Item 16G. Corporate Governance—Dutch Corporate Governance Code.”

Although shareholders have the right to approve legal mergers or demergers, Dutch law does not grant appraisal rights to a company’s shareholders who wish to challenge the consideration to be paid upon a legal merger or demerger of a company. In addition, if a third party is liable to a Dutch company, under Dutch law shareholders generally do not have the right to bring an action on behalf of the company or to bring an action on their own behalf to recover damages sustained as a result of a decrease in value, or loss of an increase in value, of their stock. Only in the event that the cause of liability of such third party to the company also constitutes a tortious act directly against such stockholder and the damages sustained are permanent, may that stockholder have an individual right of action against such third party on its own behalf to recover damages. The Dutch Civil Code provides for the possibility to initiate such actions collectively. A foundation or an association whose objective, as stated in its articles of association, is to protect the rights of persons having similar interests, may institute a collective action. The collective action cannot result in an order for payment of monetary damages but may result in a declaratory judgment ( verklaring voor recht ), for example, declaring that a party has acted wrongfully or has breached a fiduciary duty. The foundation or association and the defendant are permitted to reach (often on the basis of such declaratory judgment) a settlement that provides for monetary compensation for damages. A designated Dutch court may declare the settlement agreement binding upon all the injured parties

-27-

Table of Contents

with an opt-out choice for an individual injured party. An individual injured party, within the period set by the court, may also individually institute a civil claim for damages if such injured party is not bound by a collective agreement.

The provisions of Dutch corporate law and our Amended and Restated Articles of Association have the effect of concentrating control over certain corporate decisions and transactions in the hands of our board of directors. As a result, holders of our shares may have more difficulty in protecting their interests in the face of actions by members of the board of directors than if we were incorporated in the United States.

Exchange rate fluctuations may adversely affect the foreign currency value of the ordinary shares and any dividends.

The ordinary shares are quoted in U.S. dollars on the NYSE and in euros on Euronext Paris. Our financial statements are prepared in euros. Fluctuations in the exchange rate between euros and the U.S. dollar will affect, among other matters, the U.S. dollar value and the euro value of the ordinary shares and of any dividends.

If securities or industry analysts do not publish research or reports or publish unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our ordinary shares depends in part on the research and reports that securities or industry analysts publish about us, our business or our industry. We may have limited, and may never obtain significant, research coverage by securities and industry analysts. If no additional securities or industry analysts commence coverage of our company, the trading price for our shares could be negatively affected. In the event we obtain additional securities or industry analyst coverage, if one or more of the analysts who covers us downgrades our stock, our share price will likely decline. If one or more of these analysts, or those who currently cover us, ceases to cover us or fails to publish regular reports on us, interest in the purchase of our shares could decrease, which could cause our stock price or trading volume to decline.

We may be classified as a passive foreign investment company for U.S. federal income tax purposes, which could subject U.S. investors in our ordinary shares to significant adverse U.S. federal income tax consequences.

A foreign corporation will be a passive foreign investment company for U.S. federal income tax purposes (a “PFIC”) in any taxable year in which, after taking into account the income and assets of the corporation and certain subsidiaries pursuant to applicable “look-through rules,” either (i) at least 75% of its gross income is “passive income,” or (ii) at least 50% of its assets produce or are held for the production of “passive income.” For this purpose, “passive income” generally includes dividends, interest, royalties and rents and certain other categories of income, subject to certain exceptions. We believe that we will not be a PFIC for the current taxable year and that we have not been a PFIC for prior taxable years and we expect that we will not become a PFIC in the foreseeable future, although there can be no assurance in this regard. The determination of whether we are a PFIC is a fact-intensive determination that includes ascertaining the fair market value (or, in certain circumstances, tax basis) of all of our assets on a quarterly basis and the character of each item of income we earn. This determination is made annually and cannot be completed until the close of a taxable year. It depends upon the portion of our assets (including goodwill) and income characterized as passive under the PFIC rules. Accordingly, it is possible that we may become a PFIC due to changes in our income or asset composition or a decline in the market value of our equity. Because PFIC status is a fact-intensive determination, no assurance can be given that we are not, have not been, or will not become, classified as a PFIC.

If we were to be classified as a PFIC in any taxable year, U.S. Holders (as defined in “Item 10. Additional Information—E. Material U.S. Federal Income Tax Consequences”) generally would be subject to special tax rules that could result in materially adverse U.S. federal income tax consequences. Further, investors should assume that a “qualified electing fund” election, which, if made, could serve as an alternative to the general PFIC

-28-

Table of Contents

rules and could reduce any adverse consequences to U.S. Holders if we were to be classified as a PFIC, will not be available because we do not intend to provide U.S. Holders with the information needed to make such an election. A mark-to-market election may be available, however, if our ordinary shares are regularly traded. For more information, see “Item 10. Additional Information—E. Material U.S. Federal Income Tax Consequences—Passive Foreign Investment Company Consequences” and consult your tax advisor concerning the U.S. federal income tax consequences of acquiring, owning or disposing of our ordinary shares if we are or become classified as a PFIC.

Wise has substantial leverage and may be unable to obtain sufficient liquidity to operate its business and service its indebtedness. Constellium may elect to make capital contributions to Wise but is under no legal obligation to do so.

As of December 31, 2015, Wise had total indebtedness of €871 million, including €622 million of the Wise Senior Secured Notes ($650 million nominal amount), €145 million of the Wise Senior PIK Toggle Notes ($150 million nominal amount), and €99 million in outstanding borrowings under the Wise ABL facility.

Since Constellium acquired Wise on January 5, 2015, Wise has not generated sufficient cash flow from operations to satisfy its financial obligations and has relied on capital contributions from Constellium to compensate for its negative cash flow. For the year ended December 31, 2015, cash capital contributions from Constellium to Wise totaled €118 million. Constellium is under no legal obligation to make further capital contributions to Wise but may continue to do so to the extent permitted by the covenants under Constellium’s indebtedness.

If Constellium elects to make further investments in Wise, such investments will reduce Constellium’s cash flow available to service its indebtedness, fund working capital and capital expenditures, and for other general corporate purposes,

In addition to contributions from Constellium, Wise is also reliant on the liquidity provided by (i) the Wise ABL Facility, (ii) Wise’s receivables factoring arrangements, and (iii) trade credit provided by Wise’s commercial counterparties.

We currently expect that Wise Alloys LLC may seek to finance, at any given time, pursuant to existing and any future receivables factoring arrangements, up to $250 million of receivables that are not included in the borrowing base under the Wise ABL and cannot be financed thereunder. On March 16, 2016, Wise Alloys LLC and Wise Alloys Funding II LLC entered into the New Wise RPA with the New Wise RPA Purchaser and Greensill Capital Inc., as purchaser agent, providing for the sale of certain receivables from Wise Alloys Funding II LLC to the New Wise RPA Purchaser in an amount not to exceed $100 million in the aggregate outstanding at any time. The existing Wise RPA between Wise Alloys LLC, a Wise Alloys Funding LLC, and HSBC Bank USA, National Association does not provide for further sales of receivables after March 23, 2016. The New Wise RPA contains customary covenants and termination events. See “Item 10. Additional Information—C. Material Contracts—Wise Factoring Facilities.” If the New Wise RPA terminates or otherwise becomes unavailable, and is not extended, refinanced, or replaced, Wise’s cash collections from customers will be on longer terms than currently funded through the Wise RPA and the New Wise RPA. As a result, Wise’s liquidity could meaningfully decrease. See “Item 3. Key Information—D. Risk Factors—A deterioration in our financial position or a downgrade of our ratings by a credit rating agency could increase our borrowing costs, lead to our inability to access liquidity facilities, and adversely affect our business relationships.”

A deterioration of Wise’s financial position for any reason could also have an adverse effect on Wise’s business relationships with suppliers. If Wise is unable to obtain trade credit, or the terms of such trade credit become less favorable to Wise, Wise’s liquidity could meaningfully decrease.

If Wise’s liquidity decreases for any of the reasons set forth herein or otherwise, Wise may have insufficient liquidity to operate its business and service its indebtedness, unless another source of liquidity, which may

-29-

Table of Contents

include capital contributions from Constellium, is obtained. The Constellium Notes (as defined herein) include certain cross-default provisions that could be triggered by certain defaults under indebtedness or bankruptcy events of Wise.

Despite current indebtedness levels, we and our subsidiaries may still be able to incur substantially more debt. This could further exacerbate the risks associated with our substantial leverage.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. The terms of the indentures and agreements governing our existing indebtedness do not fully prohibit us or our subsidiaries from doing so. If new debt is added to our and our subsidiaries’ current debt levels, the related risks that we and they now face could intensify.

Our level of indebtedness could limit cash flow available for our operations and capital expenditures and could adversely affect our ability to service our debt or obtain additional financing, if necessary.

We have now and will continue to have a significant amount of indebtedness. As of December 31, 2015, we would have had, after giving effect to the Senior Secured Notes issued on March 30, 2016, total indebtedness of €2,614 million (of which €381 million would have consisted of the principal amount of the Senior Secured Notes issued on March 30, 2016, net of €9 million of issuance costs, €1,281 million of May 2014 Notes and December 2014 Notes, €871 million of debt of Wise and its direct or indirect subsidiaries, and the balance would have consisted of debt under the Ravenswood ABL Facility and other debt). Our level of indebtedness could adversely affect our operations. Among other things, our substantial indebtedness could:

In addition, the agreements governing our existing indebtedness contain financial and other restrictive covenants that will limit our ability to engage in activities that may be in our long-term best interests. Our failure to comply with those covenants could result in an event of default which, if not cured or waived, could result in the acceleration of all of our debts.

In addition, we have substantial pension and other post-employment benefit obligations, resulting in net liabilities of €701 million as of December 31, 2015.

To service our indebtedness, we will require a significant amount of cash. Our ability to generate cash depends on many factors beyond our control.

Our ability to make payments on and to refinance our indebtedness and to fund planned capital expenditures and research and development efforts will depend on our ability to generate cash in the future. Although there

-30-

Table of Contents

can be no assurances, we believe that the cash provided by our operations will be sufficient to provide for our cash requirements for the foreseeable future. However, our ability to satisfy our obligations will depend on our future operating performance and financial results, which will be subject, in part, to factors beyond our control, including interest rates and general economic, financial and business conditions. We cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to pay our indebtedness or to fund our other liquidity needs. If we are unable to generate sufficient cash flow to service our debt, we may be required to:

If we are required to take any of these actions, it could have a material adverse effect on our business, financial condition and results of operations. In addition, we cannot assure you that we would be able to take any of these actions, that these actions would enable us to continue to satisfy our capital requirements or that these actions would be permitted under the terms of our various debt instruments.

We may fail to achieve the expected benefits of the Wise Acquisition, and Wise may not have the value we anticipated prior to the consummation of the Wise Acquisition.

Since the closing of the Wise Acquisition on January 5, 2015, we have been unable to achieve the strategic, operational, financial and other benefits originally contemplated with respect to the Wise Acquisition to the full extent expected or in a timely manner, and we may not be able to achieve such benefits in the future. Constellium has recorded an impairment charge of €400 million in the fourth quarter of 2015 against the carrying value of the Wise assets. This charge, which has no impact on cash flows, reflects management’s view of the future expected performance of Wise in light of the market conditions and competitive challenges faced by Wise in its can business. We may fail to achieve the expected benefits of the Wise Acquisition and incur additional impairment.

In connection with the Wise Acquisition, we currently expect to recognize approximately $25-30 million in annual run-rate cost synergies by the end of the third year following the closing of the Wise Acquisition (which we expect to be phased in over such three-year period). However, there can be no assurance that we will realize the anticipated synergies on the currently expected timeline or at all. In addition, we could incur greater than expected one-time costs in order to achieve these synergies, in which case the net benefit to us would be less than we currently anticipate.

We may experience or be exposed to unknown or unanticipated issues, expenses, and liabilities as a result of the Wise Acquisition.

As a result of the Wise Acquisition, we may be exposed to unknown or unanticipated costs or liabilities, such as undisclosed liabilities of Wise, including those relating to environmental matters, for which we, as successor owner, may be responsible. Such unknown or unanticipated issues, expenses, and liabilities could have an adverse effect on our business, financial results and cash flows.
