SPECIAL NOTE ABOUT FORWARD-LOOKING STATEMENTS

This annual report on Form 20-F contains forward-looking statements with respect to our business, results of operations and
financial condition, and our expectations or beliefs concerning future events and conditions. You can identify certain forward-looking statements because they contain words such as, but not limited to, believes, expects,
may, should, approximately, anticipates, estimates, intends, plans, targets, likely, will, would, could
and similar expressions (or the negative of these terminologies or expressions). All forward-looking statements involve risks and uncertainties. Many risks and uncertainties are inherent in our industry and markets. Others are more specific to our
business and operations. The occurrence of the events described and the achievement of the expected results depend on many events, some or all of which are not predictable or within our control. Actual results may differ materially from the
forward-looking statements contained in this annual report on Form 20-F.

Important factors that could cause actual results to differ
materially from those expressed or implied by the forward-looking statements are disclosed under Item 3. Key InformationD. Risk Factors and elsewhere in this annual report on Form 20-F, including, without limitation, in conjunction
with the forward-looking statements included in this annual report on Form 20-F and including with respect to our estimated and projected earnings, income, equity, assets, ratios and other estimated financial results. All forward-looking statements
in this annual report on Form 20-F and subsequent written and oral forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their entirety by the cautionary statements. Some of the factors that we
believe could materially affect our results include:



| |  |  | our ability to implement our business strategy, including our productivity and cost reduction initiatives;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | competition and consolidation in the industries in which we operate;
| | - |  | --------------------------------------------------------------------



| |  |  | our susceptibility to cyclical fluctuations in the metals industry, our end-markets and our customers industries, and changes in general economic conditions;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the highly competitive nature of the metals industry and the risk that aluminium will become less competitive compared to alternative materials;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | adverse conditions and disruptions in regional and global economies, including Europe, North America and Asia;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | risk associated with our global operations, including natural disasters and currency fluctuations;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | unplanned business interruptions and equipment failure;
| | - |  | -------------------------------------------------------



| |  |  | the risk associated with being dependent on a limited number of suppliers for a substantial portion of our primary and scrap aluminium;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to maintain and continuously improve our information technology and operational systems and financial reporting and internal controls;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to manage our labor costs and labor relations;
| | - |  | ----------------------------------------------------------



| |  |  | our ability to attract and retain qualified employees;
| | - |  | ------------------------------------------------------

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.

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

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.

##### 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

##### 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 &

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

(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

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.

##### 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

##### 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.

##### 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 CivilCode 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

##### 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

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

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:



| |  |  | limit our ability to obtain additional financing for working capital, capital expenditures, research and development efforts, acquisitions and general corporate purposes;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | make it more difficult for us to satisfy leverage and fixed charge coverage ratios required for us to incur additional indebtedness under our existing indebtedness;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | make it more difficult for us to satisfy our financial obligations;
| | - |  | -------------------------------------------------------------------



| |  |  | increase our vulnerability to general adverse economic and industry conditions;
| | - |  | -------------------------------------------------------------------------------



| |  |  | require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, research
and development efforts and other general corporate purposes;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | limit our flexibility in planning for, or reacting to, changes in our business and the markets in which we compete; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | place us at a competitive disadvantage compared to our competitors that have less debt.
| | - |  | ---------------------------------------------------------------------------------------

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:



| |  |  | refinance all or a portion of our debt;
| | - |  | ---------------------------------------



| |  |  | obtain additional financing;
| | - |  | ----------------------------



| |  |  | sell some of our assets or operations;
| | - |  | --------------------------------------



| |  |  | reduce or delay capital expenditures and acquisitions;
| | - |  | ------------------------------------------------------



| |  |  | reduce or delay our research and development efforts; or
| | - |  | --------------------------------------------------------



| |  |  | revise or delay our strategic plans.
| | - |  | ------------------------------------

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.

|B. | Business Overview
|-- | -----------------

The Company

Overview

We are a global leader in
the design and manufacture of a broad range of innovative specialty rolled and extruded aluminium products, serving primarily the packaging, aerospace, and automotive end-markets. We have a strategic footprint of manufacturing facilities located in
the United States, Europe and China. Our business model is to add value by converting aluminium into semi-fabricated products. We believe we are the supplier of choice to numerous blue-chip customers for many value-added products with
performance-critical applications. Our product portfolio commands higher margins as compared to less differentiated, more commoditized fabricated aluminium products, such as common alloy coils, paintstock, foilstock and soft alloys for construction
and distribution.

As of December 31, 2015, we operated 22 production facilities, 9 administrative and commercial sites, and one
R&D center. We are building one new facility in our joint venture with UACJ Corporation in Bowling Green, USA and one new facility in Bartow County, USA, in response to growing demand for automotive in North America. We have approximately 11,000
employees. We believe our portfolio of flexible and integrated facilities is among the most technologically advanced in the industry. It is our view that our established presence in the United States and Europe and our presence in China
strategically position us to service our global customer base. We believe our well-invested facilities combined with more than 50 years of manufacturing experience, quality and innovation and preeminent R&D capabilities have put us in a
leadership position in our core markets.

We seek to sell to end-markets that have attractive characteristics for aluminium, including
(i) higher margin products, (ii) stability through economic cycles, and (iii) favorable growth fundamentals supported by substitution trends in European can sheet and automotive customers as well as order backlogs in aerospace. As of
2015, we are a leading European and North American supplier of can body stock, the leading global supplier of aluminium aerospace plates, and believe that we are the second largest provider of aluminium auto crash management systems globally. Our
unique platform has enabled us to develop a stable and diversified customer base and to enjoy long-standing relationships with our largest customers. Our customer base includes market leading firms in packaging, aerospace, and automotive, such as
Rexam PLC (Rexam), Anheuser-Busch InBev (AB InBev), Ball Corporation, Crown Holdings, Inc., Airbus, Boeing, and several premium automotive original equipment manufacturers (OEMs), including BMW AG, Daimler AG and
Ford Motor Company (Ford). Excluding Wise, the customer base of which has undergone a strategic shift since 2010 and now includes AB InBev and Coke, the average length of our customer relationships with our most significant customers
averages 25 years, and in some cases goes back as far as 40 years, particularly with our packaging and aerospace customers. Generally, we have 3 to 5 year terms in contracts with our packaging customers, five-year terms in contracts with our largest
aerospace customers, and 6 to 7 year terms in our life of a car platform/car model contracts with our automotive customers. We believe that we are a mission critical supplier to many of our customers due to our technological
and R&D capabilities as well as the long and complex qualification process required for many of our products. Our core products require close collaboration and, in many instances, joint development with our customers. We believe that this
integrated collaboration with our customers for high value-added products reduces substitution risk and creates a competitive advantage.

##### Table of Contents

There are several ways in which our business model is designed to produce stable and consistent
cash flows and profitability. For example, our pricing model allows us to pass through risks related to the volatility of commodity metal prices by charging customers London Metal Exchange (LME) aluminium prices plus a conversion
premium. We endeavor to continue to minimize our exposure to commodity metal price volatility primarily by (i) passing through aluminium price risk to customers, whereby customers pay the same metal price we receive from our suppliers,
(ii) using financial derivatives, (iii) utilizing metal owned by the customer (tolling) and (iv) aligning the price and quantity of physical aluminium purchases and sales. In addition, in 2015 we have actively re-negotiated customer
contracts at Wise, in order to mitigate the risk from Midwest premium volatility, whereby customers now pay the same Midwest premium price as we pay to our suppliers.

Our business also features relatively countercyclical cash flows. During an economic downturn, lower demand causes our sales volumes to
decrease, which results in a corresponding reduction in our working capital requirements and a positive impact on our operating cash flows. We believe this helps to drive robust free cash flow across cycles and provides significant downside
protection for our liquidity position in the event of a downturn.

For the years ended December 31, 2015, 2014 and 2013, we shipped
approximately 1,478kt, 1,062kt and 1,025kt of finished products, generated revenues of 5,153 million, 3,666 million and 3,495 million, generated net loss of 552 million, net income of 54 million
and 100 million, and generated Adjusted EBITDA of 343 million, 275 million and 280 million, respectively. The financial performance for the year ended December 31, 2015 represented a 39% increase in
shipments, a 41% increase in revenues and a 25% increase in Adjusted EBITDA from the prior year. Please see the reconciliation of Adjusted EBITDA in Item 5. Operating and Financial Review and ProspectsSegment Results.

Our objective is to expand our leading position as a supplier of high value-added, technologically advanced products in which we believe that

Recent Developments

Issuance of Senior Secured Notes

On March 30, 2016, Constellium completed a private offering of $425 million in aggregate principal amount of 7.875% Senior Secured Notes
due 2021 (the Senior Secured Notes, and together with the May 2014 Notes and the December 2014 Notes, the Constellium Notes) pursuant to an indenture among the Company, the guarantors party thereto, and Deutsche Bank Trust
Company Americas, as trustee and collateral agent. The Company invested 100 million of the net proceeds in Wise. We used and expect to continue to use the remaining net proceeds from the Constellium Notes for general corporate purposes,
including to put additional cash on our balance sheet. See Item 10. Additional InformationC. Material ContractsMarch 2016 Senior Secured Notes.

New Wise Receivables Purchase Agreement

On March 16, 2016, the New Wise RPA Seller and Wise Alloys LLC (Wise Alloys), as servicer, entered into a Receivables Purchase
Agreement with the New Wise RPA Purchaser and Greensill Capital Inc., as

purchaser agent, providing for the sale of certain receivables from the New Wise RPA Seller to the New Wise RPA Purchaser in an amount not to exceed $100 million in the aggregate outstanding at
any time. Receivables under the New Wise RPA will be sold at a discount based on a rate equal to a LIBOR rate plus 2.00-2.50% (based on the credit rating of the account debtor) per annum. No additional sales of receivables will occur under the
existing Receivables Purchase Agreement between Wise Alloys, Wise Alloys Funding LLC, and HSBC Bank USA, National Association. See Item 10. Additional InformationC. Material ContractsWise Factoring Facilities.

Expansion of Joint Venture with UACJ

On March 10, 2016, Constellium announced that it had executed a term sheet (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 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 investment needs 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.

Constellium currently expects the expanded joint venture
to result in significant benefits, helping us to become a leading player in the North American BiW market, and combining both parties strengths in technology, know-how and customer relationships.

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. See Item 3. Key InformationD. Risk Factors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 and we may be unable to execute on our strategy with respect to the joint venture with UACJ.

Impairment

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 challenges the can/ packaging business experienced in 2015. This impairment charge is reflected in our consolidated financial statements included elsewhere in this Annual Report. See Item 5. Operating and
Financial Review and Prospects.

New Manufacturing Facility

In November 2015, we announced the building of a new manufacturing facility in Bartow County, Georgia, United States, in response to growing
demand for automotive structures in North America. This project represents approximately a $20 million investment and an additional expected $12 million investment by a third-party developer, for a total project value of approximately $32 million.
Construction of the plant is expected to begin in early 2016 with start of production anticipated in 2017. We expect to create approximately 150 high-tech manufacturing jobs at this location by 2019. The planned 130,000 square foot greenfield
facility may be expanded up to 208,000 square feet to adapt to customers supply needs in the future.

CEO to retire in 2016

Pierre Vareille, our Chief Executive Officer, has informed the Board of his desire to retire during the course of 2016. The Company is
working to ensure a smooth transition, which may occur this summer. At the Boards request, Mr. Vareille has agreed to remain in his current role until his successor is appointed, and to thereafter

Packaging & Automotive Rolled Products Operating Segment

In our Packaging & Automotive Rolled Products operating segment, we produce and develop customized aluminium sheet and coil solutions.
Approximately 85% of operating segment volume for the year ended December 31, 2015 was in packaging rolled products, which primarily include beverage and food can stock as well as closure stock and foil stock. Fifteen percent of operating
segment volume for that period was in automotive and specialty and other thin-rolled products, which include technologically advanced products for the automotive and industrial sectors. Our Packaging & Automotive Rolled Products operating
segment accounted for approximately 53% of revenues and 53%(1) of Adjusted EBITDA for the year ended December 31, 2015.

As of December 2015, we are a leading European and North American supplier of can body stock and the leading worldwide supplier of closure
stock. We are also a major European player in automotive rolled products for Auto Body Sheet (the structural framework of a car), and heat exchangers. We have a diverse customer base, consisting of many of the worlds largest beverage and food
can manufacturers, specialty packaging producers, leading automotive firms and global industrial companies. Our customer base includes Rexam, AB InBev, Audi AG, Daimler AG, Peugeot S.A., Ball Corporation, Can-Pack S.A., Crown Holdings, Inc., Alanod
GmbH & Co. KG, Ardagh Group S.A., Amcor Ltd. and ThyssenKrupp AG. Our packaging contracts have usually a duration of three to five years. Our automotive contracts are usually valid for the lifetime of a model, which is typically six to
seven years.

We have two integrated rolling operations located in Europes industrial heartland and one integrated rolling operation
in Muscle Shoals, Alabama, following our acquisition of Wise Metals. Neuf-Brisach, our facility on the border of France and Germany, is, in our view, a uniquely integrated aluminium rolling and finishing facility. Singen, located in Germany, is
specialized in high-margin niche applications and has an integrated hot/cold rolling line and high-grade cold mills with special surfaces capabilities that facilitate unique metallurgy and lower production costs. We believe Singen has enhanced our
reputation in many product areas, most notably in the area of functional high-gloss surfaces for the automotive, lighting, solar and cosmetic industries, other decorative applications, closure stock, paintstock and foilstock. Muscle Shoals is a
highly focused factory mostly dedicated to can stock. After investment, the plant is expected to be capable of producing high-quality Body-in-White sheet.

Our Packaging & Automotive Rolled Products operating segment has historically been relatively resilient during periods of economic
downturn and has had relatively limited exposure to economic cycles and periods of financial instability. According to CRU International Limited (CRU), during the 2008-2009 economic crisis, can stock volumes decreased by 10% in 2009
versus 2007 levels as compared to a 24% decline for flat rolled aluminium products volumes in aggregate during the same period in Europe. This demonstrates that demand for beverage cans tends to be less correlated with general economic cycles. In
addition, we believe European can body stock has an attractive long-term growth outlook due to the following trends: (i) end-market growth in beer, soft drinks and energy drinks, (ii) increasing use of cans versus glass in the beer market,
(iii) increasing use of aluminium in can body stock in the European market, at the expense of steel, and (iv) increasing consumption in Eastern Europe linked to purchasing power growth. The U.S. can body stock market on the other hand has
seen gradual declines in volumes over the last ten years, mostly due to the decline in carbonated soft drinks consumption. Analysts expect however that the growth in Aluminium Auto Body Sheet will change the dynamic in the market, with capacity
being shifted from can body stock to Auto Body Sheet. As a result, CRU expects that by the latter part of this decade, can stock conversion fees could increase, and even a step change upward may be possible.

Aerospace & Transportation Operating Segment

Our Aerospace & Transportation operating segment has market leadership positions in technologically advanced aluminium and specialty
materials products with wide applications across the global aerospace, defense, transportation, and industrial sectors. We offer a wide range of products including plate, sheet, extrusions and precision casting products which allows us to offer
tailored solutions to our customers. We seek to differentiate our products and act as a key partner to our customers through our broad product range, advanced R&D capabilities, extensive recycling capabilities and portfolio of plants with an
extensive range of capabilities across Europe and North America. In order to reinforce the competitiveness of our metal solutions, we design our processes and alloys with a view to optimizing our customers operations and costs. This includes
offering services such as customizing alloys to our customers processing requirements, processing short lead time orders and providing vendor managed inventories or tolling arrangements. The Aerospace & Transportation operating
segment accounted for approximately 26% of our revenues and 30%(2) of Adjusted EBITDA for the year ended December 31, 2015.

In 2015, seven of our manufacturing facilities produce products that were sold via our Aerospace & Transportation operating segment.
Our aerospace plate manufacturing facilities in Ravenswood (West Virginia, United States), Issoire (France) and Sierre (Switzerland) offer the full spectrum of plate required by the aerospace industries (alloys, temper, dimensions, pre-machined) and
have unique capabilities such as producing some wide and very high gauge plates required for some aerospace programs (civil and commercial).

Downstream aluminium products for the aerospace market require relatively high levels of R&D investment and advanced technological
capabilities, and therefore tend to command higher margins compared to more commoditized products. We work in close collaboration with our customers to develop highly engineered solutions to fulfill their specific requirements. For example, we
developed AIRWARE®, a lightweight specialty aluminium-lithium alloy, for our aerospace customers to address increasing demand for lighter and more environmentally sound aircraft.

Aerospace products are typically subject to long development and supply lead times and the majority of our contracts with our largest
aerospace customers have a term of five years or longer, which provides excellent volume and profitability visibility. In addition, demand for our aerospace products typically correlates directly with aircraft backlogs and build rates. As of
December 2015, the backlog reported by Airbus and Boeing for commercial aircraft reached 12,582 units on a combined basis, representing approximately 8 to 9 years of production at current build rates.

Additionally, aerospace products are generally subject to long qualification periods. Aerospace
production sites are regularly audited by external certification organizations including the National Aerospace and Defense Contractors Accreditation Program (NADCAP) and/or the International Organization for Standardization. NADCAP is a
cooperative organization of numerous aerospace OEMs that defines industry-wide manufacturing standards. NADCAP appoints private auditors who grant suppliers like Constellium a NADCAP certification, which customers tend to require. New products or
alloys are certified by the OEM that uses the product. Our sites have been qualified by external certification organizations and our products have been qualified by our customers. We are typically able to obtain qualification within 6 months to one
year. We believe we are able to obtain such qualifications within that time frame for two main reasons. First, some new product qualifications depend on having older qualifications regarding their alloy, temper or shape which we have already
obtained through our long history of working with the main aircraft OEMs. This range of qualifications includes in excess of 100 specifications, some of which we obtained during programs dating back to the 1960s. Second, over the course of the
decades that we have been working with the aerospace OEMs, we have invested in a number of capital intensive equipment and R&D programs to be able to qualify to the current industry norms and standards.

The following table summarizes our volume, revenues and Adjusted EBITDA for our Aerospace & Transportation operating segment for the

In November 2015, we announced to build a new manufacturing facility in Bartow County, Georgia,
in response to growing demand for automotive structures in North America. Construction of the plant will begin in early 2016 with start of production anticipated in 2017. We expect to create approximately 150 high-tech manufacturing jobs at this
location by 2019. The planned 84,000 square foot greenfield facility may be expanded up to 220,000 square feet to adapt to customers supply needs in the future.

During 2015, we continued the product offering of the new aluminium high-strength (CMS) technology designed for the front and the rear of a
vehicle for enhanced structural protection in the event of a collision. Our innovative technology enables the production of aluminium CMS that are 15 percent lighter or 10 percent stronger than the current aluminium CMS on the market. The
new-generation CMS combine the properties of the 6xxx aluminium alloy familyformability, corrosion resistance, energy absorption, recyclabilitywith high-strength mechanical performance.

Fourteen of our manufacturing and engineering facilities, located in Germany, the United States, the Czech Republic, Slovakia, France,
Switzerland and China, produce products sold in our Automotive Structures & Industry operating segment. We believe our local presence, downstream services and industry leading cycle times help to ensure that we respond to our customer
demands in a timely and consistent fashion. Our two integrated remelt and casting centers in Switzerland and the Czech Republic both provide security of metal supply and contribute to our recycling efforts.

Our Industry

Aluminium Sector Value Chain

The
global aluminium industry consists of (i) mining companies that produce bauxite, the ore from which aluminium is ultimately derived, (ii) primary aluminium producers that refine bauxite into alumina and smelt alumina into aluminium,
(iii) aluminium semi-fabricated products manufacturers, including aluminium casters, extruders and rollers, and (iv) integrated companies that are present across multiple stages of the aluminium production chain.

The price of aluminium, quoted on the LME, is subject to global supply and demand dynamics and moves independently of the costs of many of its
inputs. Producers of primary aluminium have limited ability to manage the volatility of aluminium prices and can experience a high degree of volatility in their cash flows and profitability. We do not smelt aluminium, nor do we participate in other
upstream activities such as mining or refining bauxite. We recycle aluminium, both for our own use and as a service to our customers.

##### Table of Contents

Rolled and extruded aluminium product prices are generally based on the price of metal plus a
conversion fee (i.e., the cost incurred to convert the aluminium into its semi-finished product). The price of aluminium is not a significant driver of our financial performance, in contrast to the more direct relationship of the price of aluminium
to the financial performance of primary aluminium producers. Instead, the financial performance of producers of rolled and extruded aluminium products, such as Constellium, is driven by the dynamics in the end markets that they serve, their relative
positioning in those markets and the efficiency of their industrial operations.

Aluminium Rolled Products Overview

Aluminium rolled products, i.e., sheet, plate and foil, are semi-finished products that provide the raw material for the manufacture of
finished goods ranging from packaging to automotive body panels. The packaging industry is a major consumer of the majority of sheet and foil for making beverage cans, foil containers and foil wrapping. Sheet is also used extensively in transport
for airframes, road and rail vehicles, in marine applications, including offshore platforms, and superstructures and hulls of boats and in building for roofing and siding. Plate is used for airframes, military vehicles and bridges, ships and other
large vessels and as tooling plate for the production of plastic products. Foil applications outside packaging include electrical equipment, insulation for buildings, lithographic plate and foil for heat exchangers.

Independent aluminium rolled products producers and integrated aluminium companies alike participate in this market. Our rolling process
consists of passing aluminium through a hot-rolling mill and then transferring it to a cold-rolling mill, which can gradually reduce the thickness of the metal down to more than 6 mm for plates and to approximately 0.2-6 mm for sheet. We do not
produce aluminium foil.

There are two main sources of input metal for aluminium rolled or extruded products:



| |  |  | Primary aluminium, which is primarily in the form of standard ingot.
| | - |  | --------------------------------------------------------------------



| |  |  | Recycled aluminium, which comes either from scrap from fabrication processes, known as recycled process material, or from recycled end products in their end of life phase, such as beverage cans.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Whether primary or recycled, the aluminium is then cast into shapes such as:



| |  |  | Sheet ingot or rolling slab.
| | - |  | ----------------------------



| |  |  | Extrusion billets.
| | - |  | ------------------

We buy various types of metal, including primary metal from smelters in
the form of ingots, rolling slabs or extrusion billets, remelted metal from external casthouses (in addition to our own casthouses) in the form of rolling slabs or extrusion billets, production scrap from our customers, and end of life scrap.

Primary aluminium and sheet ingot can generally be purchased at prices set on the LME plus a premium that varies by geographic region on
delivery, alloying material, form (ingot or molten metal) and purity.

Recycled aluminium is also an important source of input material
and is tied to the LME pricing (typically sold at discounts of up to 20%). Aluminium is indefinitely recyclable and recycling it requires only approximately 5% of the energy required to produce primary aluminium. As a result, in regions where
aluminium is widely used, manufacturers and customers are active in setting up collection processes in which used beverage cans and other end-of-life aluminium products are collected for remelting at purpose-built plants. Manufacturers may also
enter into agreements with customers who return recycled process material and pay to have it re-melted and rolled into the same product again.

The following charts illustrate expected global demand for aluminium extruded and rolled
products. The expected growth between 2015 and 2020 for the extruded products market and the flat rolled products market is 2.5% and 4.2%, respectively.

Projected Aluminium Products Demand 2015-2020 (in thousand tons)



LOGO

The aluminium rolled products industry is characterized by economies of scale, as significant capital
investments are required to achieve and maintain technological capabilities and demanding customer qualification standards. The service and efficiency demands of large customers have encouraged consolidation among suppliers of aluminium rolled
products.

The supply of aluminium rolled products has historically been affected by production capacity, alternative technology
substitution and trade flows between regions. The demand for aluminium rolled products has historically been affected by economic growth, substitution trends, down-gauging, cyclicality and seasonality.

Aluminium Extrusions Overview

Aluminium extrusion is a technique used to transform aluminium billets into objects with a defined cross-sectional profile for a wide range of
uses. In the extrusion process, heated aluminium is forced through a die. Extrusions can be manufactured in many sizes and in almost any shape for which a die can be created. The extrusion process makes the most of aluminiums unique
combination of physical characteristics. Its malleability allows it to be easily machined and cast, and yet aluminium is one-third the density and stiffness of steel so the resulting products offer strength and stability, particularly when alloyed
with other metals.

Extruded profiles can be produced in solid or hollow form, while additional complexities can be applied using advanced
die designs. After the extrusion process, a variety of options are available to adjust the color, texture and brightness of the aluminiums finish. This may include aluminium anodizing or painting.

##### Table of Contents

Today, aluminium extrusion is used for a wide range of purposes, including components of the
transportation and industrial markets. Virtually every type of vehicle contains aluminium extrusions, including cars, boats, bicycles and trains. Home appliances and tools take advantage of aluminiums excellent strength-to-weight ratio. The
increased focus on green building is also leading contractors and architects to use more extruded aluminium products, as aluminium extrusions are flexible and corrosion-resistant. These diverse applications are possible due to the advantageous
attributes of aluminium, from its particular blend of strength and ductility to its conductivity, its non-magnetic properties and its ability to be recycled repeatedly without loss of integrity. All of these capabilities make aluminium extrusions a
viable and adaptable solution for a growing number of manufacturing needs.

Our Key End-markets

We have a significant presence in the can sheet and packaging end-markets, which have proved to be relatively stable and recession-resilient
and the aerospace end-market, which is driven by global demand trends rather than regional trends. Our automotive products are predominantly used in premium models manufactured by the German OEMs, which are not as dependent on the European economy
and continue to benefit from rising demand in developing economies, particularly China. For example, CRU International Limited reports that the consumption of automotive body sheet between 2015 and 2024 will have a growth of 19% per annum in
North America, 31% per annum in China and 13% per annum in Western Europe.

Rigid Packaging

Aluminium beverage cans represented approximately 17% of the total European aluminium flat rolled demand by volume in 2015 and 36% of total
U.S. and Canada aluminium flat rolled demand. Aluminium is a preferred material for beverage packaging as it allows drinks to chill faster, can be stacked for transportation and storage more densely than competing formats (such as glass bottles), is
highly formable for unique or differentiated branding, and offers the environmental advantage of easy, cost- and energy-efficient recycling. As a result of these benefits, aluminium is displacing glass as the preferred packaging material in certain
markets, such as beer. In Europe, aluminium is replacing steel as the standard for beverage cans. Between 2001 and 2015, we believe that aluminiums penetration of the European can stock market versus tinplate increased from 58% to 83%. In the
U.S., we believe aluminiums penetration has been at 100% for many years. In addition, we are benefitting from increased consumption in Eastern Europe and Mexico and growth in high margin products such as the specialty cans used for energy
drinks.

##### Table of Contents

In addition to expected growth, demand for can sheet has been highly resilient across economic
cycles. Between 2007 and 2009, during the economic crisis, European can body stock volumes decreased by less than 9% as compared to a 24% decline for total European flat rolled products volumes.

According to CRU, the aluminium demand for the can stock market globally is expected to grow by 3% per year between 2015 and 2020.

Aerospace

Demand for aerospace
plates is primarily driven by the build rate of aircrafts, which we believe will be supported for the foreseeable future by (i) necessary replacement of aging fleets by airline operators, particularly in the United States and Western Europe,
(ii) increasing global passenger air traffic (CRU estimates that the aerospace consumption for the aerospace market will grow at a compound annual growth rate (CAGR) of approximately
3%(4) from 2015 to 2020) and (iii) light-weighting (the substitution for lighter metals) to improve fuel efficiency and address increasingly rigorous environmental requirements.
In 2015, Boeing and Airbus predicted respectively approximately 38,000 and 32,600 new aircraft over the next 20 years across all categories of large commercial aircraft. Boeing estimates that between 2014 and 2034, 38% of sales of new airplanes will
be to Asia Pacific, 19% to Europe and 21% to North America. In early 2015, both Boeing and Airbus announced they will increase their single aisle build rates from a current 42 aircraft per month to nearly 50 to 60 monthly units by 2018.

Automotive

We supply the automotive sector with flat rolled products out of our Packaging & Automotive Rolled Products operating segment and
extrusions and automotive structures out of our Automotive Structures & Industry operating segment.

In our view, the main
drivers of automotive sales are overall economic growth, credit availability, consumer prices and consumer confidence. According to I.H.S., global light vehicle production is expected to grow from 89 million units in 2015 to 108 million
units in 2023.

Within the automotive sector, the demand for aluminium has been increasing faster than the underlying demand for light
vehicles due to recent growth in the use of aluminium products in automotive applications. We believe a main reason for this is aluminiums high strength-to-weight ratio in comparison to steel. This light-weighting facilitates better fuel
economy and improved emissions performance. As a result, manufacturers are seeking additional applications where aluminium can be used in place of steel and an increased number of cars are being manufactured with aluminium panels and crash
management systems. We believe that this trend will continue as increasingly stringent EU and U.S. regulations relating to reductions in carbon emissions, will force the automotive industry to increase its use of aluminium to lightweight
vehicles. European Union legislation sets mandatory emission reduction targets for new cars. The EU fleet average target of 130g/km in 2015 was phased in between 2012 and 2015. From 2015 onwards, all newly registered cars must comply with the limit
value curve. A shorter phase in period will apply to the target of 95g/km: 95% of each manufacturers new cars will have to comply with the limit value curve in 2020, increasing to 100% in 2021. We expect that EU and U.S. regulations requiring
reductions in carbon emissions and fuel efficiency, as well as relatively fluctuating fuel prices, will continue to drive aluminium demand in the automotive industry. Whereas growth in aluminium use in vehicles has historically been driven by
increased use of aluminium castings, we anticipate that future growth will be primarily in the kinds of extruded and rolled products that we supply to the OEMs.



LOGO

We believe that Constellium is one of only a limited number of companies that is able to produce the
quality and quantity required by car manufacturers for both flat rolled products and automotive structures, and that we are therefore well positioned to take advantage of these market trends.

Our R&D-focused approach led to the development of a number of innovative automotive product solutions; for example, Constellium worked
with Mercedes-Benz to develop an all-aluminium crash management system that reduced the systems weight by 50%. In 2015, Constellium provided Ford Motor Co. with aluminium structural parts for the all-new Ford F-150 pickup truck that
extensively uses high-strength, military-grade, aluminium alloy as a build material. In addition, increasing demand for European luxury cars in emerging

Managing Our Metal Price Exposure

Our business model is to add value by converting aluminium into semi-fabricated products. It is our policy not to speculate on metal price
movements.

For all contracts, we continuously seek to minimize the impact of aluminium price fluctuations in order to protect our net
income and cash flows against the LME price variations of aluminium that we buy and sell, with the following methods:



| |  |  | In cases where we are able to align the price and quantity of physical aluminium purchases with that of physical aluminium sales, we do not need to employ derivative instruments to further mitigate our exposure,
regardless of whether the LME portion of the price is fixed or floating.

| |  |  | However, when we are unable to align the price and quantity of physical aluminium purchases with that of physical aluminium sales, we enter into derivative financial instruments to pass through the exposure to financial
institutions at the time the price is set.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | For a small portion of our volumes, the aluminium is owned by our customers and we bear no aluminium price risk.
| | - |  | ----------------------------------------------------------------------------------------------------------------

We mark-to-market derivatives at the period end giving rise to unrealized gains or losses which are classified as other
gains/(losses)net. These unrealized gains/losses have no bearing on the underlying performance of the business and are removed when calculating Adjusted EBITDA.

The price of the aluminium that we buy comprises other premiums (or in some cases discounts) on top of the LME price. These premiums relate to
specific features of the metal being purchased, such as its location, purity, shape, etc.

The price of these premiums has been
historically relatively stable. However, between 2012 and 2014, the price of the geographical premiums (ECDU or ECDP in Europe, Midwest in North America) has risen by more than 100%, before collapsing to initial
levels. While we have always aimed at charging these premiums to our customers, the unexpected dramatic increase in the volatility has not fully been passed-through to our customers, and in the absence of a liquid and standardized market dedicated
to premiums similar to what the LME is for the LME price, the use of financial instruments (OTC derivatives) has been limited and could not cover the overall need created by the commercial exposure.

Where possible, we have changed sales and purchases contracts to align premium formulas and mitigate premium exposure. We seek to apply the
same policy and methods to minimize the impact of geographical premiums price fluctuations as we do for the LME aluminium price variations.

Sales
and Marketing

Our sales force is based in Europe (France, Germany, Czech Republic, United Kingdom, Switzerland and Italy), the
United States and Asia (Tokyo, Shanghai, Seoul, and Singapore). We serve our customers either directly or through distributors.

Raw Materials and
Supplies

Our primary metal supply is secured through long-term contracts with several upstream companies. In addition,
approximately 75% of our slab demand is produced in our casthouses. All of our top 10 suppliers have been long-standing suppliers to our plants (in many cases for more than 10 years) and in aggregate accounted for approximately 45% of our total
purchases for the year ended December 31, 2015. We typically enter into multi-year contracts with these metal suppliers pursuant to which we purchase various types of metal, including:



| |  |  | Primary metal from smelters or metal traders in the form of ingots, rolling slabs or extrusion billets.
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | Remelted metal in the form of rolling slabs or extrusion billets from external casthouses, as an addition to our own casthouses.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | Production scrap from customers and scrap traders.
| | - |  | --------------------------------------------------



| |  |  | End-of-life scrap (e.g., used beverage cans) from customers, collectors and scrap traders.
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | Specific alloying elements and primary ingots from producers and metal traders.
| | - |  | -------------------------------------------------------------------------------

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. However, in an effort to acquire
the most favorable energy costs, we have secured some of our natural gas and

electricity pursuant to fixed-price commitments. To reduce the risks associated with our natural gas and electricity requirements, we use financial futures or forward contracts with our suppliers
to fix the price of energy cost. Furthermore, in our longer-term sales contracts, we try to include indexation clauses on energy prices.

Our
Customers

Our customer base includes some of the largest leading manufacturers in the packaging. aerospace, and automotive
end-markets. We have a relatively diverse customer base with our 10 largest customers representing approximately 52% of our revenues and approximately 58% of our volumes for the year ended December 31, 2015. Excluding Wise, the customer base of
which has undergone a strategic shift since 2010 and now includes AB InBev and Coke, the average length of our customer relationships with our most significant customers averages 25 years, and in some cases goes back as far as 40 years, particularly
with our packaging and aerospace customers. Generally, we have 3 to 5 year terms in contracts with our packaging customers, five-year terms in contracts with our largest aerospace customers, and 6 to 7 year terms in our life of a car
platform/car model contracts with our automotive customers.

Most of our major packaging, aerospace and automotive customers have
multi-year contracts with us (i.e., contracts with terms of three to five years). We estimate that approximately 67% of our volumes for 2015 were generated under multi-year contracts, more than 65% were governed by contracts valid until 2016 and
more than 56% were governed by contracts valid until 2017 or later. In addition, more than 51% of our packaging volumes are contracted through 2018. This provides us with significant visibility into our future volumes and earnings.

We see our relationships with our customers as partnerships where we work together to find customized solutions to meet their evolving
requirements. In addition, we collaborate with our customers to complete a rigorous process for qualifying our products in each of our end-markets, which requires substantial time and investment and creates high switching costs, resulting in
longer-term, mutually beneficial relationships with our customers. For example, in the packaging industry, where qualification happens on a plant-by-plant basis, we are currently the exclusive qualified supplier to several facilities of our
customers.

Our product portfolio is predominantly focused on high value-added products, which we believe we are particularly well-suited
to developing and manufacturing for our customers. These products tend to require close collaboration with our customers to develop tailored solutions, as well as significant effort and investment to adhere to rigorous qualification procedures,
which enables us to foster long-term relationships with our customers. Our products typically command higher margins than more commoditized products, and are supplied to end-markets that we believe have highly attractive characteristics and
long-term growth trends.

Our Service

We believe that there are significant opportunities to improve the services and quality that we provide to our customers and to reduce our
manufacturing costs by implementing Lean manufacturing initiatives. Lean manufacturing is a production practice that improves efficiency of operations by identifying and removing tasks and process steps that do not contribute to value
creation for the end customer. We continually evaluate debottlenecking opportunities globally through modifications of and investments in existing equipment and processes. We aim to establish best-in-class operations and achieve cost reductions by
standardizing manufacturing processes and the associated upstream and downstream production elements where possible, while still allowing the flexibility to respond to local market demands and volatility.

To focus our efforts, we launched a Lean manufacturing program designed to improve the flow of value to customers by eliminating waste in both
processes and resources. We measure operational success of this program in six key areas: (i) safety, (ii) quality, (iii) acceleration of the flows and working capital reduction, (iv) delivery performance, (v) equipment
efficiency and (vi) innovation. Our Lean manufacturing program is overseen by a dedicated and experienced team with long track records of successfully implementing Lean manufacturing programs at other companies.

##### Table of Contents

The first phase of our Lean program aimed to establish a culture of continuous improvement to
accelerate our performance, increase our capacity and build a robust company; Constellium sites achieved this by improving on various areas as standardization of visual management tools, management routines or customer satisfaction. Henceforth, to
move forward, we choose to pursue with a second phase which put quality, delivery performance, and safety along with employee development at the top of the agenda. Phase 2 of the program will last until the end of 2019.

Competition

The worldwide
aluminium industry is highly competitive and we expect this dynamic to continue for the foreseeable future. We believe the most important competitive factors in our industry are: product quality, price, timeliness of delivery and customer service,
geographic coverage and product innovation. Aluminium competes with other materials such as steel, plastic, composite materials and glass for various applications. Our key competitors in our Packaging & Automotive Rolled Products operating
segment are Novelis Inc., Norsk Hydro ASA, Alcoa, Inc. and Tri-Arrows Aluminum Inc. Our key competitors in our Aerospace & Transportation operating segment are Alcoa, Inc., Aleris International, Inc., Kaiser Aluminum Corp., Austria Metall
AG, and Universal Alloy Corporation. Our key competitors in our Automotive Structures & Industry operating segment are Sapa AB, Sankyo Tateyama, Inc., Eural Gnutti S.p.A., Otto Fuchs KG, Impol Aluminium Corp., Benteler International AG and
YKK.

Research and Development

We
believe that our research and development capabilities coupled with our integrated, longstanding customer relationships create a distinctive competitive advantage versus our competition. Our R&D center is based in Voreppe, France and provides
services and support to all of our facilities. The R&D center focuses on product and process development, provides technical assistance to our plants and works with our customers to develop new products. In developing new products, we focus on
increased performance that aims to lower the total cost of ownership for the end users of our products, for example, by developing materials that decrease maintenance costs of aircraft or increase fuel efficiency in cars. As of December 31,
2015, the research and development center employs 242 employees, including approximately 108 scientists and 104 technicians.

Within the
Voreppe facility, we also focus on the development, improvement, and testing of processes used in our plants such as melting, casting, rolling, extruding, finishing and recycling. We also develop and test technologies used by our customers, such as
friction stir welding and automotive hoods bumping and provide technological support to our customers.

The key contributors to our
success in establishing our R&D capabilities include:



| |  |  | Close interaction with key customers, including through formal partnerships or joint development teamsexamples include Strongalex®, Formalex® and Surfalex®, which were developed with automotive Auto Body Sheet customers (mainly Daimler and Audi) and the Fusion bottle, a draw wall
ironed technology created in partnership with Rexam.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Technologically advanced equipment.
| | - |  | -----------------------------------



| |  |  | Long-term partnerships with European universitiesfor example, Swiss Technology Partners and École Polytechnique Fédérale de Lausanne in Switzerland generate significant innovation
opportunities and foster new ideas.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We invested 35 million in research and development in the year ended
December 31, 2015, 38 million in the year ended December 31, 2014, and 36 million in the year ended December 31, 2013.

Trademarks, Patents, Licenses and IT

In connection with the acquisition, Rio Tinto assigned or licensed to us certain patents, trademarks and other intellectual property rights. In
connection with our collaborations with universities such as the École Polytechnique Fédérale de Lausanne and other third parties, we occasionally obtain royalty-bearing licenses for the use of third-party technologies in the
ordinary course of business.

We actively review intellectual property arising from our operations and our research and development
activities and, when appropriate, apply for patents in the appropriate jurisdictions. We currently hold approximately 170 active patent families and regularly apply for new ones. While these patents and patent applications are important to the
business on an aggregate basis, we do not believe any single patent family or patent application is critical to the business.

We are from
time to time involved in opposition and re-examination proceedings that we consider to be part of the ordinary course of our business, in particular at the European Patent Office, the U.S. Patent and Trademark Office, and the State Intellectual
Property Office of the Peoples Republic of China. We believe that the outcome of existing proceedings would not have a material adverse effect on our financial position, results of operations or cash flows.

Insurance

We have implemented a
corporate-wide insurance program consisting of both corporate-wide master policies with worldwide coverage and local policies where required by applicable regulations. Our insurance coverage includes: (i) property damage and business
interruption; (ii) general liability including operation, professional, product and environment liability; (iii) aviation product liability; (iv) marine cargo (transport); (v) business travel and personal accident;
(vi) construction all risk (EAR/CAR); (vii) automobile liability; (viii) trade credit; and (ix) other specific coverages for executive and special risk.

We believe that our insurance coverage terms and conditions are customary for a business such as Constellium and are sufficient to protect us
against catastrophic losses.

We also purchase and maintain insurance on behalf of our directors and officers.

Governmental Regulations and Environmental, Health and Safety Matters

Our operations are subject to a number of federal, state and local regulations relating to the protection of the environment and to workplace
health and safety. Our operations involve the use, handling, storage, transportation and disposal of hazardous substances, and accordingly we are subject to extensive federal, state and local laws and regulations governing emissions to air,
discharges to water emissions, the generation, storage, transportation, treatment or disposal of hazardous materials or wastes and employee health and safety matters. In addition, prior operations at certain of our properties have resulted in
contamination of soil and groundwater which we are required to investigate and remediate pursuant to applicable environmental, health and safety (EH&S) laws. Environmental compliance at our key facilities is overseen by the Direction
Régionale de lEnvironnement de lAménagement et du Logement in France, the Umweltbundesamt in Germany, the Service de la Protection de lEnvironnement du Canton du Valais in Switzerland, the West Virginia Department of
Environmental Protection, the Alabama Department of the Environmental Management and the Kentucky Department for Environmental Protection in the United States, the Regional Authority of the Usti Region in the Czech Republic, the Slovenká
Inpekcia ivotného prostredia in Slovakia, and the Environmental Monitoring Agency in China. Violations of EH&S laws, and remediation obligations arising under such laws, may result in restrictions being imposed on our
operating activities as well as fines, penalties, damages or other costs. Accordingly, we have implemented EH&S policies and procedures to protect the environment and ensure compliance with these laws, and incorporate EH&S considerations
into our planning for new projects. We perform regular risk assessments and EH&S reviews. We closely and systematically monitor and manage situations of noncompliance with EH&S

laws and cooperate with authorities to redress any noncompliance issues. We believe that we have made adequate reserves with respect to our remediation obligations. Nevertheless, new regulations
or other unforeseen increases in the number of our non-compliant situations may impose costs on us that may have a material adverse effect on our financial condition, results of operations or liquidity.

Our operations also result in the emission of substantial quantities of carbon dioxide, a greenhouse gas that is regulated under the EUs
Emissions Trading System (ETS). Although compliance with ETS to date has not resulted in material costs to our business, compliance with ETS requirements currently being developed for the 2016-2020 period, and increased energy costs due
to ETS requirements imposed on our energy suppliers, could have a material adverse effect on our business, financial condition or results of operations. We may also be liable for personal injury claims or workers compensation claims relating
to exposure to hazardous substances. In addition, we are, from time to time, subject to environmental reviews and investigations by relevant governmental authorities.

Directive 2010/75 titled Industrial Emissions regulates some of our European activities as recycling or melting/casting. With the forthcoming
final revision of the Best Available Technics Reference in 2016, which will define associated emissions limits values for these activities, within the next 4 years, staying in compliance with the law, could require significant expenditures to tune
our processes or implement abatement installations.

Additionally, some of the chemicals we use in our fabrication processes are subject
to REACH 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. We are currently compliant with REACH, and expect to stay in compliance,
but if the nature of the regulation changes in the future or if substances we use currently in our process, considered as Substances of Very High Concern, fall under need of authorization for use, 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. Future noncompliance could also subject us to significant fines or other civil and criminal penalties.
Obtaining regulatory approvals for chemical products used in our facilities is an important part of our operations.

We accrue for costs
associated with environmental investigations and remedial efforts when it becomes probable that we are liable and the associated costs can be reasonably estimated. The aggregate close down and environmental restoration costs provisions at
December 31, 2015 were 88 million. All accrued amounts have been recorded without giving effect to any possible future recoveries. With respect to ongoing environmental compliance costs, including maintenance and monitoring, we expense
the costs when incurred.

We have incurred, and in the future will continue to incur, operating expenses related to environmental
compliance. As part of the general capital expenditure plan, we expect to incur capital expenditures for other capital projects that may, in addition to improving operations, reduce certain environmental impacts as energy consumption, air emissions,
water releases, wastes streams optimization.

Litigation and Legal Proceedings

From time to time, we are party to a variety of claims and legal proceedings that arise in the ordinary course of business. The Company is
currently not involved, nor has it been involved during the twelve-month period immediately prior to the date of this Annual Report, in any governmental, legal or arbitration proceedings which may have or have had a significant effect on the
Companys business, financial position or profitability, and the Company is not aware of any such proceedings which are currently pending or threatened. From time to time, asbestos-related claims are also filed against us, relating to historic
asbestos exposure in our production process. Constellium has implemented internal controls to comply with applicable environmental law. We have made reserves for potential occupational disease claims for a total of 5 million as of
December 31, 2015. It is not anticipated that any of our currently pending litigation and proceedings will have a material effect on the future results of the Company.

North American can body stock market, a number one position in global aerospace plates and a leading global position as aluminium automotive structures provider. This global leadership is
supported by our well-invested facilities in Europe and the United States, as well as more than 50 years of proven ability to deliver manufacturing quality and innovation, a global sales network and pre-eminent R&D capabilities.

As of December 31, 2015, we had approximately 11,000 employees and 22 state-of-the-art, integrated production facilities, 9
administrative and commercial sites, and one R&D center.

Our product portfolio is predominantly focused on high value-added,
technologically advanced specialty products that command higher margins than less differentiated aluminium products. This portfolio serves a broad range of end-markets that exhibit attractive growth trends in future periods such as the aerospace and
automotive markets. Our technological advantage and relationship with our customers is driven by our pre-eminent R&D capabilities. We believe that our R&D capabilities are a key attraction for our customers. Many projects are designed to
support specific commercial opportunities at the request of our customers and are carried out in partnership with them.

This regular
interaction and partnership with our customers also help us maintain our leading market positions. We have long-standing, established relationships with some of the largest companies in the packaging, aerospace, automotive and other transportation
industries including Rexam, Crown, Ball and Amcor, Boeing, Airbus, as well as a number of leading automotive firms. Excluding Wise, the customer base of which has undergone a strategic shift since 2010 and now includes AB InBev, the average length
of our customer relationships amongst our top 20 customers averages 25 years.

Our primary metal supply is secured through long-term
contracts with several upstream companies, including affiliates of Rio Tinto. In addition, a material portion of our slab and billet supply is produced in our own casthouses.

The table below presents our revenue, net income or loss from continuing operations and Adjusted EBITDA in the years ended December 31,
2015, 2014 and 2013. A reconciliation of the net income from continuing operations to Adjusted EBITDA is included in Segment Results.

Our Operating Segments

We serve a diverse set of customers across a broad range of end-markets with very different product needs, specifications and requirements. As
a result, we have organized our business into the following three segments to better serve our customer base:

Packaging & Automotive
Rolled Products Segment

Our Packaging & Automotive Rolled Products segment produces and develops customized aluminium
sheet and coil solutions. Approximately 85% of segment volume for the year ended December 31, 2015 was in packaging applications, which primarily include beverage and food can stock as well as closure stock and foil stock. Fifteen percent of
segment volume for that period was in automotive rolled products. Our Packaging & Automotive Rolled Products segment accounted for 53% of revenues and 53%(1) of Adjusted EBITDA for the
year ended December 31, 2015.

##### Table of Contents

Aerospace & Transportation Segment

Our Aerospace & Transportation segment has market leadership positions in technologically advanced aluminium and specialty materials
products with wide applications across the global aerospace, defense, transportation, and industrial sectors. We offer a wide range of products including plate and sheet which allows us to offer tailored solutions to our customers. We seek to
differentiate our products and act as a key partner to our customers through our broad product range, advanced R&D capabilities, extensive recycling capabilities and portfolio of plants with an extensive range of capabilities across Europe and
North America. In order to reinforce the competitiveness of our metal solutions, we design our processes and alloys with a view to optimizing our customers operations and costs. This includes offering services such as customizing alloys to our
customers processing requirements, processing short lead time orders and providing vendor managed inventories or tolling arrangements. Aerospace & Transportation accounted for 26% of our revenues and 30%(1) of Adjusted EBITDA for the year ended December 31, 2015.

Automotive Structures &
Industry Segment

Our Automotive Structures & Industry segment produces (i) technologically advanced structures for
the automotive industry, including crash management systems, side impact beams and cockpit carriers and (ii) soft and hard alloy extrusions and large extruded profiles for automotive, rail, road, energy, building and industrial applications. We
complement our products with a comprehensive offering of downstream technology and service activities, which include pre-machining, surface treatment, R&D and technical support services. Our Automotive Structures & Industry segment
accounted for 20% of revenues and 23%(1) of Adjusted EBITDA for the year ended December 31, 2015.

Discontinued Operations and Disposals

In
the first quarter of 2015, we decided to dispose of our plant in Carquefou (France) which is part of our A&T operating segment and accordingly it was classified as held for sale at December 31, 2015. An 8 million charge was
recorded upon the write-down of the related assets to their net realizable value. The sale was completed on February 1, 2016 and no gain was recognized upon disposal.

In the year ended December 31, 2014, the sale of our Tarascon-sur-Ariège (Sabart) plant in France was completed generating a
7 million loss on disposal. This operation did not meet the criteria of discontinued operations in accordance with IFRS and therefore has not been classified or disclosed as such.

In the year ended December 31, 2013, we sold two of our soft alloy plants in France, Ham and Saint Florentin, which did not meet the
criteria of discontinued operations in accordance with IFRS and therefore have not been classified or disclosed as such. We have excluded the revenue or shipments from these plants in some of our analysis, where indicated, to allow comparison of
period-over-period production.

In the year ended December 31, 2013, the investment in Alcan Strojmetal Aluminium Forging s.r.o.,
previously accounted for under the equity method, was sold, generating a 3 million disposal gain.

Key Factors Influencing
Constelliums Financial Condition and Results from Operations

Acquisition of Wise

On January 5, 2015, we acquired 100% of Wise , a private aluminium sheet producer located in Muscle Shoals, Alabama, United States of
America. As we have a controlling interest in the acquired business, its results of operations have been consolidated as of the date of the acquisition. Given the size of the acquired business relative to our legacy businesses and the timing of the
Wise Acquisition, the consolidation of the results of the acquired business have had a significant impact on our cash flows and the year over year change in certain key line items of the consolidated statement of income. To the extent our cash flows
or the change in an income

statement item was significantly impacted by the addition of Wise to our consolidated results in the year ended December 31, 2015, we have indicated this and excluded the associated
impact when discussing the results of our analysis of the year over year changes. The full results of Wise since its acquisition are included in the results of our P&ARP segment.

The Aluminium Industry

We
participate in select segments of the aluminium semi-fabricated products industry, including rolled and extruded products. Aluminium is lightweight, has a high strength-to-weight ratio and is resistant to corrosion. It compares favorably to several
alternative materials, such as steel, in these respects. Aluminium is also unique in the respect that it recycles repeatedly without any material decline in performance or quality. The recycling of aluminium delivers energy and capital investment
savings relative to the cost of producing both primary aluminium and many other competing materials. Due to these qualities, the penetration of aluminium into a wide variety of applications continues to increase. We believe that long-term growth in
aluminium consumption generally, and demand for those products we produce specifically, will be supported by factors that include growing populations, purchasing power and increasing focus globally on sustainability and environmental issues.
Aluminium is increasingly seen as the material of choice in a number of applications, including packaging, aerospace and automotive.

We
do not mine bauxite, refine alumina, or smelt primary aluminium as part of our business. Our industry is cyclical and is affected by global economic conditions, industry competition and product development.

The financial performance of our operations is dependent on several factors, the most critical of which are as follows:

Volumes

The profitability of our
businesses is determined, in part, by the volume of tons sold and processed. Increased production volumes will result in lower per unit costs, while higher sold volumes will result in additional revenues and associated margins.

Price and Margin

For all
contracts, we continuously seek to minimize the impact of aluminium price fluctuations in order to protect our net income and cash flows against the LME and premium/aluminium price variations of aluminium that we buy and sell, with the following
methods:



| |  |  | In cases where we are able to align the price and quantity of physical aluminium purchases with that of physical aluminium sales, we do not need to employ derivative instruments to further mitigate our exposure,
regardless of whether the LME portion of the price is fixed or floating.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | However, when we are unable to align the price and quantity of physical aluminium purchases with that of physical aluminium sales, we enter into derivative financial instruments to pass through the exposure to financial
institutions at the time the price is set.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | For a small portion of our volumes, the aluminium is owned by our customers and we bear no aluminium price risk.
| | - |  | ----------------------------------------------------------------------------------------------------------------

We do not apply hedge accounting for the derivative instruments we enter into in connection with our ongoing commercial activities and
therefore any mark-to-market movements for these instruments are recognized in other (losses)/gainsnet (note that we did apply hedge accounting to the derivative instruments we entered into in connection with the Wise Acquisition).
Our risk management practices aim to reduce, but do not eliminate, our exposure to changing primary aluminium prices and, while we limit our exposure to unfavorable price changes, we also limit our ability to benefit from favorable price changes.

##### Table of Contents

In addition, our operations require that a significant amount of inventory be kept on hand to
meet future production requirements. The value of the base level of inventory is also susceptible to changing primary aluminium prices. In order to reduce these exposures, we focus on reducing inventory levels and offsetting future physical
purchases and sales.

We refer to the timing difference between the price of primary aluminium included in our revenues and the price of
aluminium impacting our cost of sales as metal price lag.

Also included in our results is the impact of differences between
changes in the prices of primary and scrap aluminium. As we price our product using the prevailing price of primary aluminium but purchase large amounts of scrap aluminium to produce our products, we benefit when primary aluminium price increases
exceed scrap price increases. Conversely, when scrap price increases exceed primary aluminium price increases, our results are negatively impacted. The difference between the price of primary aluminium and scrap prices is referred to as the
scrap spread and is impacted by the effectiveness of our scrap purchasing activities, the supply of scrap available and movements in the terminal commodity markets.

The price we pay for aluminium also includes regional premiums, such as the Rotterdam premium for metal purchased in Europe or the Midwest
premium for metal purchased in the U.S. The regional premiums which had historically been fairly stable have recently become more volatile. Notably, regional premiums increased significantly in 2013 and 2014, with the Rotterdam premium and the
Midwest premium reaching unprecedented levels in the fourth quarter of 2014. During the second half of 2015, both the Rotterdam and Midwest premiums returned to levels seen prior to 2013. Although our business model seeks to minimize the impact of
aluminium price fluctuations on our net income and cash flows, we are not always able to pass-through the cost of regional premiums to our customers or adequately hedge the impact of regional premium differentials. We refer to this exposure as
metal premium losses. See Item 3. Key InformationD. Risk FactorsOur financial results could be adversely affected by the volatility in aluminium prices.

Seasonality

Customer demand in
the aluminium industry is cyclical due to a variety of factors, including 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 the
lowest volumes typically delivered in August and December and highest volumes delivered in January to June. 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 seasons, whereas the automotive and construction sectors encounter slowdowns in both the third and fourth quarters of the calendar year. In response to this seasonality, we seek to scale back and may even
temporarily close some operations to reduce our operating costs during these periods.

Economic Conditions, Markets and Competition

We are directly impacted by the economic conditions that affect our customers and the markets in which they operate. General economic
conditions in the geographic regions in which our customers operatesuch as the level of disposable income, the level of inflation, the rate of economic growth, the rate of unemployment, exchange rates and currency devaluation or
revaluationinfluence consumer confidence and consumer purchasing power. These factors, in turn, influence the demand for our products in terms of total volumes and the price that can be charged. In some cases we are able to mitigate the risk
of a downturn in our customers businesses by building committed minimum volume thresholds into our commercial contracts. We further seek to mitigate the risk of a downturn by utilizing a temporary workforce for certain operations, which allows
us to match our resources with the demand for our services. We are also seeking to purchase transportation and logistics services from third parties, to the extent possible, in order to limit capital expenditure and manage our fixed cost base.

##### Table of Contents

Although the metals industry and our end-markets are cyclical in nature and expose us to related
risks, we believe that our portfolio is relatively resistant to these economic cycles in each of our three main end-markets (packaging, aerospace and automotive):



| |  |  | Can packaging is a seasonal market peaking in the summer because of the increased consumption of soft drinks during the summer months. It tends not to be highly correlated to the general economic cycle and in addition,
we believe European can body stock has an attractive long-term growth outlook due to ongoing trends in (i) end-market growth in beer, soft drinks and energy drinks, (ii) increasing use of cans versus glass in the beer market, and
(iii) increasing penetration of aluminium in can body stock at the expense of steel.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We believe that the aerospace industry is currently insulated from the economic cycle through a combination of drivers sustaining its growth. These drivers include increasing passenger traffic and the replacement of the
fleet fueled by the age of the planes in service and the need for more efficient planes. These factors have materialized in the form of historically high backlogs for the aircraft manufacturers; the combined order backlog for Boeing and Airbus
currently represents approximately 8 to 9 years of manufacturing at current delivery rates.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Although the automotive industry as a whole is a cyclical industry, its demand for aluminium has been increasing in recent years. This has been triggered by the light-weighting demand for new car models, which drives a
positive substitution of heavier metals in favor of aluminium.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition to the counter-cyclicality of our key
end-markets, we believe our cash flows are also largely protected from variations in LME prices due to the fact that we hedge our sales based on their replacement cost, by setting the maturity of our futures on the delivery date to our customers. As
a result, when LME prices increase, we have limited additional cash requirements to finance the increased replacement cost of our inventory. Aluminium prices are determined by worldwide forces of supply and demand, and, as a result, aluminium prices
are volatile. The average LME transaction price per ton of primary aluminium in 2015, 2014 and 2013 was 1,498, 1,410 and 1,390, respectively.

The average quarterly LME per ton using U.S. dollar prices converted to euros using the applicable European Central Bank rates are presented
in the following table:

A portion of our revenues are denominated in U.S. dollars while the majority of our costs incurred are
denominated in local currencies. We engage in significant hedging activity to attempt to mitigate the effects of foreign transaction currency fluctuations on our profitability.

In accordance with IFRS, we mark-to-market derivatives at the period end giving rise to unrealized gains or losses which are classified as
other (losses)/gainsnet. These unrealized gains or losses have no bearing on the underlying performance of the business and are removed when calculating Adjusted EBITDA.

Personnel Costs

Our operations
are labor intensive and, as a result, our personnel costs represent 18%, 20%, and 20% of our cost of sales, selling and administrative expenses and research and development expenses for the years ended December 31, 2015, 2014, and 2013
respectively. Personnel costs generally increase and decrease proportionately with the expansion, addition or closing of operating facilities. Personnel costs include the salaries, wages and benefits of our employees, as well as costs related to
temporary labor. During our seasonal peaks and especially during summer months, we have historically increased our temporary workforce to compensate for staff on vacation and increased volume of activity.

Currency

We are a global company
with operations as of December 31, 2015 in France, the United States, Germany, Switzerland, the Czech Republic, Slovakia and China. As a result, our revenue and earnings have exposure to a number of currencies, primarily the U.S. dollar, the
euro and the Swiss Franc. As our presentation currency is the euro, and the functional currencies of the businesses located outside of the Eurozone are primarily the U.S. dollar and the Swiss franc, the results of the businesses located outside of
the Eurozone must be translated each period to euros. Accordingly, fluctuations in the exchange rate of the functional currencies of our businesses located outside of the Eurozone against the euro impacts our results of operations. This impact is
referred to as the effect of foreign currency translation in the Results of Operations discussion below. We calculate the effect of foreign currency translation by converting our current period local currency financial
information using the prior period foreign currency average exchange rates and comparing these adjusted amounts to our prior period reported results. This calculation may differ from similarly titled measures used by other companies and,
accordingly, the changes excluding the effect of foreign currency translation are not meant to substitute for changes in recorded amounts presented in conformity with IFRS nor should such amounts be considered in isolation. When discussing the
revenue and Adjusted EBITDA of our P&ARP segment we exclude the impact of the Wise Acquisition on year over year changes. As Wise is the only business within our P&ARP segment with a functional currency that is different from our
presentation currency, year over year changes that exclude the impact of the Wise Acquisition are not impacted by the effect of foreign currency translation.

Transaction impacts arise when our businesses transact in a currency other than their own functional currency. As a result, we are exposed to
foreign exchange risk on payments and receipts in multiple currencies. Where we have multiple-year sale agreements for the sale of fabricated metal products in U.S. dollars, we have entered into derivative contracts to forward sell U.S. dollars to
match these future sales. Hedge accounting is not applied to such ongoing commercial transactions and therefore the mark-to-market impact is recorded in other gains/(losses)net.

Revenue

Revenue from continuing operations increased by 41% or 1,487 million to 5,153 million for the year ended
December 31, 2015, from 3,666 million for the year ended December 31, 2014. Excluding the impact of the acquisition of Wise, which contributed 1,198 million of revenue in the year ended December 31, 2015, and the
effect of foreign currency translation, revenue increased 125 million or 3%.

Excluding the impact of the Wise Acquisition, our
volumes decreased by 3%, or 27 kt, to 1,035 kt for the year ended December 31, 2015 compared to shipments of 1,062 kt for the year ended December 31, 2014. This decrease is primarily driven by lower shipment volumes from our P&ARP
segment attributable to a decline in volumes of 28 kt or 5%, excluding the impact of the Wise Acquisition, over the period. The year over year decline in volumes was offset by a 6% increase in revenue per ton from 3,452 per ton in the
year ended December 31, 2014 to 3,663 per ton in the year ended December 31, 2015, excluding the impact of the Wise Acquisition and the effect of foreign currency translation. This was primarily driven by favorable mix
attributable to higher average prices on automotive and aerospace products.

Our revenue is discussed in more detail in the
Segment Results section.

Cost of Sales and Gross Profit

Cost of sales increased by 48%, or 1,520 million, to 4,703 million for the year ended December 31, 2015, from
3,183 million for the year ended December 31, 2014. Excluding the impact of the acquisition of Wise, which contributed 1,219 million of cost of sales in the year ended December 31, 2015, and the effect of foreign
currency translation, cost of sales increased by 5%, or 159 million.

Excluding the impact of the Wise Acquisition and the effect of
foreign currency translation, the increase in cost of sales is driven by the following:



| |  |  | A 7% or 140 million increase in the total cost of raw material and consumables used. Although total
shipment volumes declined as explained further in the Revenue section above, the raw material and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | consumables cost per ton increased by 9%, reflective of the impact of metal price lag which changed from a positive impact in 2014 to a negative impact in 2015 (72 million negative impact
on cost of sales over the period) and higher combined LME prices and premium in the earlier part of 2015 and late 2014 over the comparable period in the prior year;
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A 7% or 38 million increase in employee benefit expenses in cost of sales driven by an increase in headcount across our businesses to support the continued expansion of our aerospace and automotive production
capabilities and 6 million of non-recurring employee benefit related manufacturing system and process transformation and start-up and development costs;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A 31 million increase in depreciation and amortization in cost of sales driven by increased investment in our production facilities in prior years to support our operations and respond to market demand.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The decrease in metal premium losses over the period had a 15 million positive impact on gross profit and
further investments in manufacturing system and process transformation related costs at businesses within our A&T segment in 2015 and increased start-up and development costs at businesses within our AS&I and P&ARP segments had an
offsetting negative impact on gross profit over the period. Excluding the impact of these items on our gross profit and the impact of metal price lag, and despite the other factors described above, our gross profit margin as a percentage of revenue
increased slightly to 14% in the year ended December 31, 2015 from 13% in the year ended December 31, 2014, excluding the impact of the Wise Acquisition and the effect of foreign currency translation.

Selling and Administrative Expenses

Selling and administrative expenses increased by 23%, or 45 million, to 245 million for the year ended December 31,
2015 from 200 million for the year ended December 31, 2014. Excluding the impact of the acquisition of Wise, which contributed 19 million in selling and administrative expenses in the year ended December 31, 2015, and
the effect of foreign currency translation, the increase was 10%, or 19 million, driven by a 14 million increase in employee benefit expenses included in selling, general, and administrative expenses. The increase in employee
related expenses is both attributable to an increase in support functions headcount and external workforce to support future expansion combined with non-recurring costs related to the turnover in executive personnel and increase in share equity
plans.

Research and Development Expenses

Research and development expenses decreased by 8% or 3 million, to 35 million in the year ended December 31, 2015,
from 38 million in the year ended December 31, 2014. Wise did not contribute research and development expenses in the year ended December 31, 2015. Excluding the impact of 9 million in French research and development
tax credits (9 million in the year ended December 31, 2014), research and development costs were 12 million, 20 million, 9 million, and 3 million at the P&ARP, A&T, AS&I, and
Corporate & Holding segments, respectively, in the year ended December 31, 2015.

Restructuring Costs

Restructuring costs decreased by 4 million to 8 million in the year ended December 31, 2015, from
12 million in the year ended December 31, 2014.

Impairment

Impairment charges of 457 million were recorded in the year ended December 31, 2015 while no impairment charges were recorded
in the year ended December 31, 2014. The charges recorded during the period are primarily comprised of a 49 million impairment related to our operations in Valais, Switzerland within the AS&I and A&T segments and a
400 million impairment related to Wise within our P&ARP segment. The

##### Table of Contents

Valais impairment was triggered by a combination of factors including unfavorable exposure to the strengthening Swiss franc during the period and declining market share in the aerospace market.
The Wise impairment was triggered by continued under performance and actual results for the year ended December 31, 2015 showing a much lower financial performance than the initial business plan prepared as part of the Wise Acquisition, and the
downgrade of the revised budget and strategic plan, notably after taking into account the commercial conditions of new sale agreements for the can/packaging business.

Other lossesnet were 131 million for the year ended December 31, 2015 compared to
83 million for the year ended December 31, 2014.

Realized losses recognized upon the settlement of derivative instruments
increased by 80 million, to 93 million for the year ended December 31, 2015, from 13 million for the year ended December 31, 2014. Of these, realized losses on LME derivatives were 56 million in
the year ended December 31, 2015 compared to 3 million in the year ended December 31, 2014. The year over year increase in the LME related loss is attributable to the decline in LME prices throughout the year. Realized losses on
foreign exchange derivatives increased by 25 million to 37 million in the year ended December 31, 2015 from 12 million in the year ended December 31, 2014 as a result of the strengthening of the U.S. dollar
against the euro.

Unrealized losses on derivatives held at fair value through profit and loss were 20 million in the year
ended December 31, 2015 compared to 53 million in the year ended December 31, 2014. Of these, mark-to-market unrealized losses recognized on LME related derivative instruments were 10 million in the year ended
December 31, 2015 compared to 12 million in the year ended December 31, 2014. The mark-to-market unrealized losses recognized on foreign exchange derivatives, which relate primarily to the exposure on a multiple year sale
agreement for products sold in U.S. dollars, which ends in 2016, decreased from 41 million in the year ended December 31, 2014 to 10 million in the year ended December 31, 2015. The year over year change can be
attributed to a decrease in the notional value as of the end of 2015 compared to the end of 2014 as we near the end the agreement.

In the
years ended December 31, 2015 and 2014, we recognized a 5 million loss and 9 million gain, respectively, associated with amendments made to our Ravenswood pension benefit plans.

The loss on disposal and assets classified as held for sale in the year ended December 31, 2015 primarily relates to the write-down of
the value of assets at our plant in Carquefou, France upon our decision to sell the plant during the year. The loss recognized in the year ended December 31, 2014 primarily relates to the disposal of our Tarascon sur Ariege plant in October
2014.

Finance Cost-Net

Finance costsnet increased by 97 million, to 155 million for the year ended December 31, 2015, from
58 million in the year ended December 31, 2014. Finance costsnet is comprised of finance costs of 226 million and 88 million in the years ended December 31, 2015 and 2014, respectively, and finance
income of 71 million and 30 million in the years ended December 31, 2015 and 2014, respectively.

Finance costs
increased by 138 million to 226 million for the year ended December 31, 2015, from 88 million for the year ended December 31, 2014. Excluding the impact of the acquisition of Wise, which contributed
61 million (net of the amortization of borrowing costs) of finance costs in the year ended December 31, 2015, finance costs increased by 87%, or 77 million. The increase in finance costs, excluding the impact of the Wise
Acquisition, is primarily attributable to an increase in interest expense recognized on borrowings, an increase in realized and unrealized exchange losses on financing activities, and the offsetting impact of the absence of exit fees paid and the
write-off of unamortized arrangement fees associated with the repayment of the 2013 Term Loan recognized in the year ended December 31, 2014.

Finance income increased by 41 million, to 71 million in the year ended December 31, 2015 from
30 million in the year ended December 31, 2014. There was no finance income contributed by Wise in the year ended December 31, 2015. The increase in finance income is primarily attributable to an increase in realized and
unrealized gains on debt derivatives and an increase in realized and unrealized gains on financing activities, which almost fully offset the losses included in finance costs.

Interest expense recognized on borrowings, excluding the interest expense contributed by Wise of 66 million, increased by
51 million to 83 million for the year ended December 31, 2015 from 32 million for the year ended December 31, 2014. The increase is mainly attributable to a full year of interest expense recognized on our
Senior Notes issued in May and December 2014.

In the year ended December 31, 2014, we recognized 15 million of exit and
arrangement fees related to the repayment of the 2013 Term Loan. No such fees were incurred in the year ended December 31, 2015. Interest expense on our factoring arrangements were stable over the period, being 11 million for the
year ended December 31, 2015, and 9 million for the year ended December 31, 2014.

We recognized a net
48 million loss related to realized and unrealized exchange losses on financing activities in the year ended December 31, 2015 compared to a loss of 27 million in the year ended December 31, 2014. This activity is
primarily comprised of foreign exchange transaction losses related to the revaluation of a portion of the Senior Notes denominated in U.S. dollars, which resides at euro functional currency entities, and is driven by the further strengthening of the
U.S. dollar over the period. We have entered in to cross currency swaps and rolling foreign exchange forwards in order to offset this exposure to currency rate volatility. Realized and unrealized gains, included in finance income, recognized on the
settlement and mark-to-market revaluation of these instruments, of 50 million and 29 million were recognized in the year ended December 31, 2015 and 2014, respectively.

Income Tax

Income tax for the
year ended December 31, 2015 was a benefit of 32 million compared to an income tax expense of 37 million for the year ended December 31, 2014.

Our effective tax rate represented 5% of our loss before income tax for the year ended December 31, 2015 and 41% of our income before tax
for the year ended December 31, 2014. This 36 percentage point change in our effective tax rate reflects an increase in composite statutory tax rate applicable by tax jurisdiction (the blended tax rate), from 31% in 2014 to
38 % in 2015 and significant reconciling items in both years.

Revenue

Revenue from continuing operations increased by 5% or 171 million to 3,666 million for the year ended December 31,
2014, from 3,495 million for the year ended December 31, 2013. This increase can be attributed to a 4% increase in volumes shipped and stable average LME prices. On a like-for-like basis, revenues increased by 5%, excluding the
impact of changes in LME metal prices, premiums and currency exchange rates, when compared to the full year 2013. Revenues per ton were stable at 3,452 per ton in the year ended December 31, 2014 compared to 3,410 per ton
in the year ended December 31, 2013.

Our volumes increased by 4%, or 37kt, to 1,062 kt for the year ended December 31, 2014
compared to shipments of 1,025 kt for the year ended December 31, 2013. The increase reflects higher shipment volumes from our P&ARP and AS&I segment, despite the sale of Ham and Saint-Florentin, two of our soft alloy plants in France.

Our revenues are discussed in more detail in the Segment Results section.

Cost of Sales and Gross Profit

Cost of sales increased by 5%, or 159 million, to 3,183 million for the year ended December 31, 2014 from
3,024 million for the year ended December 31, 2013, in line with the increase in shipments and aluminium prices. Higher LME prices and premiums contributed to a 5%, or 92 million, increase in raw materials and consumable
expenses to 1,952 million for the year ended December 31, 2014, as compared to 1,860 million in the year ended December 31, 2013.

##### Table of Contents

On a per ton basis, cost of sales increased by 2% to 2,997 per ton in the year ended
December 31, 2014, from 2,950 per ton in the year ended December 31, 2013, due primarily to higher spot prices for aluminium and premiums. Our raw materials cost per ton increased by 1% to 1,838 per ton in 2014.

Our gross profit benefitted from our accounting for inventory under the weighted average cost method. Due to LME price movements and the
timing of transfers from inventory to cost of sales the effect of metal price lag improved our gross profit by 27 million in the year ended December 31, 2014 compared to a negative impact of 29 million in the year ended
December 31, 2013.

Employee benefit expenses recorded in cost of sales increased by 7% or 36 million, to
548 million for the year ended December 31, 2014, from 512 million for the year ended December 31, 2013, reflecting increases in salaries and in headcount.

Depreciation and impairment increased by 17 million to 49 million for the year ended December 31, 2014, from
32 million for the year ended December 31, 2013, reflecting our level of investments. As a result of the combination of the multiple factors described above, gross profit increased by 12 million or 3%, to
483 million for the year ended December 31, 2014 from 471 million for the year ended December 31, 2013. Our gross profit margin remained stable at 13% of revenues in the years ended December 31, 2014 and 2013.

Selling and Administrative Expenses

Selling and administrative expenses decreased by 5%, or 10 million, to 200 million for the year ended December 31,
2014 from 210 million for the year ended December 31, 2013.

Consulting and audit fees decreased by 20%, or
10 million, to 40 million for the year ended December 31, 2014, from 50 million for the year ended December 31, 2013. External consulting expenses related primarily to costs incurred in preparing for and
operating as a publicly traded company following our IPO in May 2013.

Other selling & administrative expenses, including
personnel expenses recorded in selling and administrative expenses, were stable at 160 million in both years ended December 31, 2014 and 2013, reflecting our continuous efforts to contain our costs.

Research and Development Expenses

Research and development expenses increased by 6% or 2 million, to 38 million in the year ended December 31, 2014,
from 36 million in the year ended December 31, 2013.

Restructuring Costs

Restructuring expenses increased by 50% or 4 million, to 12 million for the year ended December 31, 2014, from
8 million for the year ended December 31, 2013.

Other lossesnet were 83 million for the year ended December 31, 2014 compared to
8 million for the year ended December 31, 2013.

Other losses-net for the year ended December 31, 2014 included
34 million costs in connection with our acquisition of Wise, which was finalized in January 2015.

Unrealized (losses)/gains on
derivatives held at fair value through profit and loss were a loss of 53 million in the year ended December 31, 2014 compared to a gain of 12 million in the year ended December 31, 2013. Of these, unrealized losses on
LME derivatives were 7 million in the year ended December 31, 2014 compared to 7 million in the year ended December 31, 2013. Unrealized gains and losses on foreign exchange derivatives relate primarily to the
exposure on a multiple year sale agreement for products sold in U.S. dollars and the appreciation of the U.S. dollar compared to the euro in 2014 led to unrealized losses on foreign exchange derivatives of 41 million compared to a gain of
21 million in the year ended December 31, 2013.

Realized losses on derivatives decreased by 18 million, to
13 million for the year ended December 31, 2014, from 31 million for the year ended December 31, 2013. Of these, realized losses on LME derivatives were nil in the year ended December 31, 2014 compared to
29 million in the year ended December 31, 2013. Realized losses on foreign exchange derivatives were a loss of 12 million in the year ended December 31, 2014 compared to a loss of 1 million in the year
ended December 31, 2013.

In the years ended December 31, 2014 and 2013, we recognized a 9 million and
11 million gain, respectively, associated with amendments to our Ravenswood pension benefit plans reducing employee benefits and resulting in recognition of negative past service cost. In the year ended December 31, 2014, we
recognized an 8 million gain related to certain contractual reimbursements of income tax from a previous shareholder.

Loss on
disposal in the year ended December 31, 2014 and 2013 relates primarily to the disposal of our Tarascon sur Ariege plant in October 2014 and our Saint Florentin and Ham plants in May 2013 and amounted to 5 million in both periods.

Other Expenses

Other
expenses were 27 million in the year ended December 31, 2013 (nil in the year ended December 31, 2014) and related to fees incurred in connection with our IPO in May 2013, amounting to 24 million, and with our
secondary public offerings, amounting to 3 million.

Finance Cost-Net

Finance costsnet increased by 16%, or 8 million, to 58 million for the year ended December 31, 2014, from
50 million in the year ended December 31, 2013.

Finance costs increased by 27 million, or 40%, to
94 million for the year ended December 31, 2014, from 67 million for the year ended December 31, 2013 as a result of our refinancings.

Interest expense on borrowings increased by 10 million to 32 million for the year ended December 31, 2014, from
22 million for the year ended December 31, 2013, mainly attributable to the Senior Notes we issued in May 2014 and December 2014. In the year ended December 31, 2014, we recognized:



| |  |  | 23 million of interest expensed and accrued associated with the May and December Notes (nil in 2013)
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | 7 million of interest expensed associated with our 2013 Term Loan, which was repaid with the proceeds from our May 2014 Notes. Our 2013 Term Loan had replaced our 2012 Term Loan we entered into in May 2012
and in the year ended December 31, 2013 we recognized 17 million and 3 million interest associated with our 2013 and 2012 Term Loan, respectively.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Following the refinancing we recognized 15 million of exit and arrangement fees related to the repayment of the 2013 Term Loan in the year ended December 31, 2014 and 21 million following the
repayment of the 2012 Term Loan in the year ended December 31, 2013.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Interest expense on our factoring arrangements
were stable over the period, being 9 million for the year ended December 31, 2014, and 10 million for the year ended December 31, 2013.

Our realized and unrealized gains and losses on debt derivatives at fair valuenet relate to the cross currency swap which was settled
when the 2013 Term Loan was repaid and represent a 29 million gain for the year ended December 31, 2014 and a 9 million loss for the year ended December 31, 2013. We also recognized an 11 million
gainnet related to unrealized and realized exchange gains on financing activities during the year ended December 31, 2013 compared to a 27 million net loss for the year ended December 31, 2014, reflecting the strengthening
of the U.S. dollar over the period.

Income Tax

Income tax expenses decreased by 5% or 2 million, to 37 million for the year ended December 31, 2014, from
39 million for the year ended December 31, 2013. Our effective tax rate increased by 12 percentage points from 29% for the year ended December 31, 2013 to 41% for the year ended December 31, 2014. This 12 percentage point
increase in our effective tax rate reflects the following:



| |  |  | a 12 percentage point unfavorable impact from the derecognition of the deferred tax assets of one of our Swiss entities,
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | a 3 percentage point unfavorable impact from liquidation losses in 2014 as opposed to net gains on divestments in 2013,
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | a 2 percentage point unfavorable impact from non-deductible interest expense primarily in France,
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | a 5 percentage point favorable impact from the mix of profits as a result of a lower weight of profits in higher tax rate jurisdictions (most notably the United States).

Net Income for the Year from Continuing Operations

Net income from continuing operations was 54 million for the year ended December 31, 2014 compared to 96 million for
the year ended December 31, 2013, representing a decrease of 42 million. Gross profit margin

remained stable and the decrease was primarily attributable to unrealized losses on derivatives of 53 million in fiscal year 2014 compared to unrealized gains on derivatives of
12 million in fiscal year 2013. In addition, fiscal year 2014 was impacted by 34 million of transaction costs related to the Wise Acquisition while the fiscal year 2013 had been impacted by 27 million of expenses
related to our IPO and subsequent offerings.

Discontinued Operations

Net income from discontinued operations of 4 million in the year ended December 31, 2013 (nil in the year ended
December 31, 2014) represented the impact of the agreement reached with the acquirer of our former AIN business.

P&ARP. Revenues in our P&ARP segment increased by 75%, or 1,174 million, to
2,742 million in the year ended December 31, 2015, from 1,568 million for the year ended December 31, 2014. Excluding the impact of the acquisition of Wise, which contributed 1,198 million to the
segments revenue in the year ended December 31, 2015, revenue decreased by 24 million or 2%. Excluding the impact of the Wise Acquisition, shipments decreased by 5% or 28 kt, to 592 kt for the year ended December 31, 2015,
from 620 kt for the year ended December 31, 2014, driven by a 35 kt or 7% decrease in shipments of our packaging rolled products. The year over year decline in volumes is attributable to lower demand from can stock customers due to challenges
and competition experienced in 2015, which was partially offset by automotive rolled product volume growth. A 3% increase in average prices from 2,529 per ton in the year ended December 31, 2014 to 2,608 in the year ended
December 31, 2015, excluding the impact of the Wise Acquisition, partially offset the impact of the decline in volumes on the segments revenue.

Revenues in our P&ARP segment increased by 7%, or 96 million, to 1,568 million in the year ended December 31,
2014, from 1,472 million for the year ended December 31, 2013. Excluding the impact of LME and foreign exchange variations, our revenue would have increased by 6% over the period. Shipments increased by 4% or 25 kt, to 620 kt for the
year ended December 31, 2014, from 595kt for the year ended December 31, 2013, driven by a 20kt or 36% increase in shipments of automotive rolled products as our BiW projects ramped up which contributed 63 million to the revenue
increase. Stable packaging shipments contributed an additional 22 million to revenue as a result of increased average selling prices, with segment revenue per ton increasing by 2% to 2,529 / ton for the year ended December 31,
2014, from 2,474 / ton for the year ended December 31, 2013.

A&T. Revenue at our A&T segment increased
by 156 million, or 13% from 1,192 million in the year ended December 31, 2014 to 1,348 million in the year ended December 31, 2015. Excluding the effect of foreign currency translation, the segments
revenue increased by 39 million, or 3% over the period. Our volumes decreased by 7 kt, or 3% from 238 kt in the year ended December 31, 2014 to 231 kt in the year ended

##### Table of Contents

December 31, 2015, driven primarily by a 15 kt decrease in shipments of our transportation, industry, and other rolled products, which can be attributed to softer customer demand in
the transportation and industry markets in 2015. This was partially offset by an 8 kt, or 7% increase in aerospace rolled product volume. Excluding the effect of foreign currency translation, revenue per ton increased by 6% from 5,008 per
ton in the year ended December 31, 2014 to 5,329 per ton in the year ended December 31, 2015, primarily driven by favorable mix within the aerospace product line.

Revenues in our A&T segment was stable, at 1,192 million for the year ended December 31, 2014, from
1,197 million for the year ended December 31, 2013. Our volumes decreased by 2%, or 6 kt, to 238 kt for the year ended December 31, 2014 from 244 kt for the year ended December 31, 2013, mostly attributable to a 4kt
decrease in shipments of our aerospace rolled products. Excluding the impact of LME and foreign exchange, our revenue decreased by 1% over the period, in line with the decrease in shipments and following the adverse impact of a less favorable sales
mix in aerospace and competitive pressure in our non-aerospace applications. Revenue per ton increased by 2% to 5,008 / ton for the year ended December 31, 2014, from 4,906 / ton for the year ended December 31, 2013.

AS&I. Revenues in our AS&I segment increased by 18%, or 159 million, to 1,034 million for the year
ended December 31, 2015, from 875 million for the year ended December 31, 2014. Excluding the effect of foreign currency translation, segment revenues increased by 13%, or 112 million, primarily driven by an 11%
increase in revenue per ton, from 4,207 per ton in the year ended December 31, 2014 to 4,656 per ton in the year ended December 31, 2015. Volumes remained stable, with a slight increase in automotive shipments offset
by a decrease in the shipment of other products. The year over year improvement in revenue per ton can be attributed to a 21% increase within our automotive product line mainly due to favorable unit spread on sales to automotive customers.

Revenues in our AS&I segment increased by 9%, or 70 million, to 875 million for the year ended
December 31, 2014, from 805 million for the year ended December 31, 2013. On a like-for-like basis, revenues for AS&I increased by 7% in 2014, adjusting for the sale of two of our soft alloy plants in 2013 and excluding the
favorable effect of LME metal prices, premiums, and foreign exchange impacts. Our segment volumes increased by 9% or 17kt to 208kt for the year ended December 31, 2014, from 191 kt for the year ended December 31, 2013, driven by an
additional 19kt shipped in automotive extruded products. Revenue per ton was stable at 4,207 per ton for the year ended December 31, 2014.

Holdings and Corporate. Revenues in the Holdings and Corporate segment for the years ended December 31, 2015, 2014, and
2013 related primarily to metal sales to our former soft alloy plants.

Adjusted EBITDA

In considering the financial performance of the business, management analyzes the primary financial performance measure of Adjusted EBITDA in
all of our business segments. Adjusted EBITDA is not a measure defined by IFRS. We believe the most directly comparable IFRS measure to Adjusted EBITDA is our net income or loss for the relevant period.

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

Our CODM measures the profitability and
financial performance of our operating segments based on Adjusted EBITDA. Adjusted EBITDA is defined as income from continuing operations before income taxes, results from joint ventures, net finance costs, other expenses and depreciation and
amortization as adjusted to

exclude restructuring costs and impairment charges, unrealized gains or losses on derivatives and on foreign exchange differences, metal price lag, Share Equity Plan expense, effects of purchase
accounting adjustments, start-up costs or acquisition, integration and separation costs, certain incremental costs and other exceptional, unusual or generally non-recurring items.

Adjusted EBITDA has limitations as an analytical tool. It is not a measure defined by IFRS and therefore does not purport to be an alternative
to operating profit or net income as a measure of operating performance or to cash flows from operating activities as a measure of liquidity.

Adjusted EBITDA is not necessarily comparable to similarly titled measures used by other companies. As a result, you should not consider these
performance measures in isolation from, or as a substitute analysis for, our results of operations.

The following table shows
Constelliums consolidated Adjusted EBITDA for the years ended December 31, 2015, 2014 and 2013:

Total Adjusted EBITDA for the year ended December 31, 2015 was 343 million, an increase
compared to 275 million of total Adjusted EBITDA for the year ended December 31, 2014. Excluding the impact of the acquisition of Wise, which contributed 68 million of Adjusted EBITDA in the year ended December 31,
2015, and the effect of foreign currency translation, Adjusted EBITDA decreased by 4% or 10 million over the period to 265 million and represented 7% of revenues in the year ended December 31, 2015. Excluding Holdings and
Corporate, this decrease mainly reflects the net positive impact of improved shipment performance and mix at our AS&I segment, favorable product mix at the A&T segment, and lower shipment volumes at P&ARP segment, offset by increased
spending during the year to support future growth and operational quality.

P&ARP. Adjusted EBITDA at our P&ARP
segment increased by 55%, or 65 million, to 183 million for the year ended December 31, 2015, from 118 million for the year ended December 31, 2014. Excluding the impact of the acquisition of Wise, which
contributed 68 million of Adjusted EBITDA to this segment in the year ended December 31, 2015, Adjusted EBITDA decreased by 3 million or 3% and Adjusted EBITDA per ton increased by 2% from 190 per ton in the
year ended December 31, 2014 to 194 per ton in the year ended December 31, 2015. Overall, Adjusted EBITDA remained relatively stable. Lower shipment volumes, which had a negative impact of 14 million, were offset by
better mix on the sale of higher margin automotive products, which had a positive impact of 8 million, as well as premium loss favorability and better control of production costs and overhead spending.

Adjusted EBITDA in our P&ARP segment increased by 12%, or 13 million, to 118 million for the year ended
December 31, 2014, from 105 million for the year ended December 31, 2013. Adjusted EBITDA per ton increased by 8% over the same period, to 190 per ton for the year ended December 31, 2014, from 176 per
ton for the year ended December 31, 2013, driven by increases across all product categories. Increased shipments in automotive rolled products contributed to a 14 million increase while price and mix had a limited negative effect of
1 million as the impact of a richer mix was offset by 6 million of increase in premiums not passed through to customers. Costs and inflation led to a 7 million decrease, mostly associated with labor inflation, while
foreign exchange had a 4 million positive impact.

A&T. Adjusted EBITDA at our A&T segment increased by 13%, or
12 million, for the year ended December 31, 2015 to 103 million, compared to 91 million for the year ended December 31, 2014. Excluding the effect of foreign currency translation, Adjusted EBITDA increased
by 4% or 4 million over the period and Adjusted EBITDA per ton increased by 8% from 380 per ton in the year ended December 31, 2014 to 411 per ton. Shipments slightly decreased year over year however our
shipments to high-end defense and aerospace customers, which typically carry higher margins due to a higher level of aluminium conversion complexity, increased, contributing to an overall positive price and mix effect of 43 million. Increased
spending over the period to enhance our quality performance and optimize cost productivity had an offsetting impact of 31 million on Adjusted EBITDA.

Adjusted EBITDA in our A&T segment decreased by 24%, or 29 million, for the year ended December 31, 2014 to
91 million, compared to 120 million for the year ended December 31, 2013. Adjusted EBITDA in our A&T segment decreased to 380 per ton for the year ended December 31, 2014 from 491 per ton for
the year ended December 31, 2013. This decrease reflected the lower shipments for 7 million and a negative price and mix effect for 28 million, including 8 million related to the increase in premiums throughout
the year. The performance of our A&T segment for the year ended December 31, 2014, was also impacted by capacity constraints and operational issues, including significant unplanned equipment outages at our Ravenswood facility in the first
and fourth quarters. This was partially offset by lower costs for 2 million and the positive impact of the strengthening of the U.S. dollar for 8 million.

AS&I. Adjusted EBITDA at our AS&I segment increased by 10%, or 7 million, in the year ended December 31,
2015 to 80 million, compared to 73 million for the year ended December 31, 2014. Excluding the effect of foreign currency translation, Adjusted EBITDA increased by 7% or 5 million over the period and Adjusted
EBITDA per ton increased by 5% from 351 per ton in the year ended December 31, 2014 to 368 per ton in the year ended December 31, 2015. In the year ended December 31, 2015, higher automotive volumes, mainly
driven by growing demand from OEMs in the North American market, contributed to favorable pricing and mix effect. The combined impact of volumes, pricing, and mix had a 28 million positive impact on the year over year Adjusted EBITDA
growth. The automotive favorability was partially offset by increased costs incurred during the year ended December 31, 2015 to support our expansion in to the automotive market and increased maintenance and research and development costs over
the period to support enhanced future performance.

Adjusted EBITDA in our AS&I segment increased by 26%, or
15 million, for the year ended December 31, 2014 to 73 million, compared to 58 million for the year ended December 31, 2013. Adjusted EBITDA per ton in our AS&I segment increased by 16% to
351 per ton for the year ended December 31, 2014 from 311 per ton for the year ended December 31, 2013, driven by positive contributions from all product lines. The 9% increase in shipments represented a further
24 million, partially offset by 13 million incremental costs and inflation, mainly related to labor inflation, a 1 million negative price and mix effect including 9 million impact of the increase in
premiums which were not passed through to customers, and 1 million associated with the unfavorable change in foreign exchange.

Holdings and Corporate. Our Holdings and Corporate segment generated Adjusted EBITDA losses of 23 million,
7 million and 3 million in the years ended December 31, 2015, 2014 and 2013. The increase in the loss from the year ended December 31, 2014 to the year ended December 31, 2015 is primarily attributable to
theimpact of non-recurring costs incurred in the current period and the reversal of an environmental provision in the year ended December 31, 2014, which, together, contributed approximately 7 million of the year over
year change. Foreign currency transactional losses at our Swiss corporate entity driven by the strengthening of the Swiss franc against the Euro during the period along with increased employee benefit expense also contributed significantly to the
remaining balance of the year over year change.

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

| |  |  | Wise Mid-West premium losses: Constellium seeks to achieve a full pass-through model for LME and premiums, primarily through contractual arrangements with metal suppliers and customers. At the acquisition date (January
5, 2015), not all Wise contracts had this pass-through mechanism. Constellium has renegotiated these contracts to bring them in line with its usual practice. In addition, the Mid West Premium market conditions were abnormal in the year ended
December 31, 2015 with premium falling from $524/metric ton as at January 5, 2015 to $198/metric ton as at December 31, 2015. This resulted in an un-recovered metal premium of 22 million.

Our debt agreements contain no maintenance covenants and events of default but contain customary affirmative and negative covenants that, among
other things, restrict, subject to certain exceptions, our ability and the ability of our subsidiaries, to incur indebtedness, sell assets, make investments, engage in acquisitions, mergers or consolidations and make dividends and other restricted
payments.

The Unsecured Revolving Credit Facility was terminated on March 30, 2016 in connection with the issuance of the Senior
Secured Notes. The Ravenswood ABL Facility described in Item 10. Additional InformationC. Material ContractsRavenswood ABL Facility, contains a financial maintenance covenant that requires Constellium Rolled Products
Ravenswood, LLC (Ravenswood) to maintain excess availability of the greater of (i) $10 million and (ii) 10% of the aggregate revolving loan commitments. Ravenswood is currently in compliance with this financial maintenance
covenant. The Ravenswood ABL Facility also contains customary negative covenants on liens, investments and restricted payments related to Ravenswood.

The Wise ABL Facility requires the maintenance of a fixed charge coverage ratio if the excess availability falls below the greater of 10% of
the aggregate revolving loan commitment and $20 million. Wises excess availability as of December 31, 2015 was above 10% of the aggregate borrowing base and was greater than $20 million and as such, the company was not required to comply
with the ratio requirement.

We were in compliance with our covenants throughout 2015 and 2014 and as of December 31, 2015 and 2014.

Liquidity and Capital Resources

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

As part of our cash flow management, we have improved our net working capital through procurement initiatives designed to leverage economies
of scale and improve terms of payment to suppliers, as well as through collection initiatives designed to improve our billings and collections processes to reduce outstanding receivables. We define net working capital days, days of inventories, days
of payables and days of sales outstanding as net trade working capital, inventories, trade payables and trade receivables divided by revenues for the last quarter, multiplied by 90, respectively. Net trade working capital is inventories plus trade
receivables net, less trade payables. We believe this measure helps users of the financial statements compare our cash management from period to period and against our peers in respect to our efficiency of working capital employed and the ability to
provide sufficient liquidity in the short and long term. Our net working capital as a percentage of annual revenue decreased from 6% in 2013 and 2014 to 3% in 2015. Excluding the impact of factoring 429 million of receivables at the end
of 2015, 145 million of which was related to Wise, and the impact of factoring 94 million of receivables at the end of 2014, our net working capital as a percentage of annual revenue

increased from 8% at December 31, 2014 to 11% at December 31, 2015, primarily driven by Wise. While inventory at Wise has significantly decreased during the year driven by improved
inventory control and supply chain optimization, the net working capital as a percentage of annual revenue was 18%, excluding the impact of factoring. Excluding Wise and after adjusting for the impact of factoring, our net working capital as a
percentage of annual revenues was 7% in the year ended December 31, 2015, representing a slight decrease from the year ended December 31, 2014.

Based on our current and anticipated levels of operations, and the condition in our markets and industry, we believe that our cash on hand,
cash flows from operations, and availability under our revolving credit facilities will enable us to meet our working capital, capital expenditures, debt service and other funding requirements for the foreseeable future. However, our ability to fund
working capital needs, debt payments and other obligations depends on our future operating performance and cash flows and many factors outside of our control, including the costs of raw materials, the state of the overall industry and financial and
economic conditions and other factors, including those described under the following risk factors within Item 3. Key InformationD. Risk Factors.



| |  |  | 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;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

It is our policy to hedge all highly probable or committed foreign currency operating cash flows. As
we have significant third party future receivables denominated in U.S. dollars, we enter into combinations of forward contracts and currency options with financial institutions, selling forward U.S. dollars against euros. In addition, as discussed
in Item 4. Information on the CompanyB. Business OverviewManaging our Metal Price Exposure, when we are unable to align the price and quantity of physical aluminium purchases with that of physical aluminium sales, we enter
into derivative financial instruments to pass through the exposure to metal price fluctuations to financial institutions at the time the price is set. As the U.S. dollar appreciates versus the euro or the LME price for aluminium falls, the
derivative contracts entered into with financial institution counterparties have a negative mark-to-market. Our financial institution counterparties may require margin calls should our negative mark-to-market exceed a pre-agreed contractual limit.
In order to protect the Company from the potential margin calls for significant market movements, we hold a significant liquidity buffer in cash or in availability under our various borrowing facilities, we enter into derivatives with a large number
of financial counterparties and we monitor margin requirements on a daily basis for adverse movements in the U.S. dollar versus the euro and in aluminium prices. No margins were posted at December 31, 2015 or December 31, 2014.

At December 31, 2015, we had 733 million of total liquidity, comprised of 472 million in cash and cash equivalents,
56 million of undrawn credit facilities under our ABL facilities, 50 million available under our factoring arrangements, 145 million of undrawn credit facilities under our Unsecured Revolving Credit Facility, and
10 million under a revolving credit facility. Our ability to borrow under the Unsecured Revolving Credit Facility is subject to financial covenants with which we were compliant at December 31, 2015. The Unsecured Revolving Credit
Facility was terminated on March 30, 2016 in connection with the issuance of the Senior Secured Notes.

Net cash from operating activities

Net cash from operating activities increased by 299 million, from an inflow of 212 million in the year ended
December 31, 2014, to an inflow of 511 million in the year ended December 31, 2015. The year over year increase in operating cash flows is primarily attributable to a 335 million increase in the amount of receivables
factored at the end of the year and the liquidation of the acquired Wise receivables during the year. This inflow was partially offset by the impact of the timing of vendor payments made.

Net cash from operating activities increased by 28 million, from an inflow of 184 million in the year ended
December 31, 2013, to an inflow of 212 million for the year ended December 31, 2014. Net working capital days decreased by 5 days to 20 days for the year ended December 31, 2014, from 25 days for the year ended
December 31, 2013. The increase in LME prices and foreign exchange drove all components of trade working capital up, especially inventories and in our A&T segment. Payables were also impacted by the expenses related to the Wise Acquisition,
which were incurred in Q4 2014.

Net cash from investing activities

Cash flows used in investing activities increased by 506 million to 722 million for the year ended December 31,
2015, from 216 million for the year ended December 31, 2014, mainly driven by the net consideration paid in connection with the Wise Acquisition of 348 million, a 151 million increase in capital expenditures,
71 million of which was contributed by Wise. Cash flows used in investing activities also included 9 million related to an additional investment in joint ventures.

Cash flows used in investing activities increased by 84 million to 216 million for the year ended December 31,
2014, from 132 million for the year ended December 31, 2013, mainly driven by a 55 million increase in capital expenditures, to 199 million for the year ended December 31, 2014, from 144 million
for the year ended December 31, 2013. Our capital expenditures for the year included 36 million related to the ramp up of our body-in-white projects in our PA&RP segment, a further 12 million spent on projects related
to Airware and major maintenance in our A&T segment. Cash flows used in investing activities also included 19 million related to our investment in joint ventures, which was created during the fourth quarter of 2014.

The main projects undertaken during the year ended December 31, 2015 included the Body-in-White capacity
extension and the conversion of the Muscle Shoals plant acquired in 2015 from a can-stock to automotive product production facility within the P&ARP segment, and projects related to the Airware casthouse and capital investments, mainly at our
Issoire and Ravenswood, West Virginia facilities, to support improved production capacity and manufacturing efficiency within the A&T segment.

Capital expenditures increased by 151 million, or 76%, to 350 million for the year ended December 31, 2015, from
199 million in the year ended December 31, 2014, as a result of the continuation of existing projects and new projects, including 62 million spent on Body-in-White projects in Europe and the U.S. and 21 million
spent on Airware-related projects which were in progress during 2014. Expenditures related to new projects included 33 million related to production capacity improvements at our A&T facilities and 39 million related to the

Pension Obligations

Constellium operates various pension plans for the benefit of its employees across a number of countries. Some of these plans are defined
benefit plans and others are defined contribution plans. The largest of these plans are in the United States, Switzerland, Germany and France. Pension benefits are generally based on the employees service and highest average eligible
compensation before retirement, and are periodically adjusted for cost of living increases, either by practice, collective agreement or statutory requirement.

We also provide health and life insurance benefits to retired employees and in some cases to their beneficiaries and covered dependents. These
plans are predominantly in the United States.

United States pensions and healthcare plans

In the United States, we operate defined benefit plans, which, as of December 31, 2015, covered 1,159 active participants, 597 deferred
participants and 1,981 retired employees.

There is a defined contribution (401(k)) savings plan and an unfunded post-employment
benefit scheme.

Wise contributed 8 million in the Groups net defined benefit obligation.

Switzerland

As of
December 31, 2015, there were 785 employees and 114 retired employees in the Swiss pension plan.

Germany

In Germany, there are a number of defined benefit and defined contribution pension schemes, which, as of December 31, 2015, covered a
total of 1,466 active participants, 469 deferred participants and 2,765 retired employees.

France

In France, there are unfunded defined benefit pension plans and a healthcare plan, which, as of December 31, 2015, covered 3,909 active
participants and 563 retired employees.

Our pension liabilities and other post-retirement healthcare obligations are reviewed regularly
by a firm of qualified external actuaries and are revalued taking into account changes in actuarial assumptions and experience. The assumptions include assumed discount rates on plan liabilities and expected rates of return on plan assets. Both of
these require estimates and projections on a variety of factors and these can fluctuate from period to period.

For the year ended
December 31, 2015, the total expense recognized in the income statement in relation to all our pension and post-retirement benefits was 48 million (compared to 30 million for the year ended December 31, 2014). At
December 31, 2015, the fair value of the plans assets was 362 million (compared to 330 million as of December 31, 2014), compared to a present value of our obligations of 1,063 million (compared to
987 million as of December 31, 2014), resulting in an aggregate plan deficit of 701 million (compared to 657 million as of December 31, 2014).

Contributions to pension plans totaled 32 million for the year ended December 31, 2015 (compared to 34 million for
the year ended December 31, 2014). Contributions for other benefits totaled 18 million for the year ended December 31, 2015 (compared to 15 million for the year ended December 31, 2014).

##### Table of Contents

Our estimated funding for our funded pension plans and other post-retirement benefit plans is
based on actuarial estimates using benefit assumptions for discount rates, rates of compensation increases, and health care cost trend rates. The deficit related to the funded pension plan and the present value of the unfunded obligations as of
December 31, 2015 were 319 million and 382 million, respectively. The deficit related to funded pension plan and the present value of the unfunded obligations as of December 31, 2014 were 282 million and
375 million, respectively. Estimating when the obligations will require settlement is not practicable and therefore these have not been included in the Contractual Obligations table above.

Below is a brief description of the compensation and benefit plans in which our officers participate.

Executive Performance Award Plan

Each of our officers participates in the EPA. The EPA is an annual cash bonus plan intended to provide performance-related award opportunities
to employees who contribute substantially to the success of Constellium. Under the EPA, participants are granted opportunities to earn cash bonuses (expressed as a percentage of base salary) based on the level of achievement of certain financial
metrics established by our remuneration committee for the applicable annual performance period, environmental, health and safety (EHS) performance objectives approved by our remuneration committee and individual and team objectives
established by the applicable participants supervisor. The level of attainment of awards granted under the EPA is generally

##### Table of Contents

determined to be 70% based on the level of attainment of the applicable financial metrics, 10% based on the level of attainment of EHS performance objectives and 20% based on the level of
attainment of individual and team objectives. Awards are paid (generally subject to continued service through the end of the applicable annual performance period) in the year following the year for which such awards were granted.

Long Term Incentive Cash Plan

The Long Term Incentive Cash Plan is intended to motivate and retain certain key senior employees of Constellium who are not eligible to
participate in our management equity plan described below. Approximately 60 of our senior employees were selected by our remuneration committee to receive grants of cash awards under the Long Term Incentive Cash Plan. Participants award
opportunities are based on job grade, with the amount earned in respect of such awards based on the level of attainment of the applicable performance criteria for the applicable measurement years. Awards earned under the plan are generally paid in
the third year following the applicable measurement year, with the awards generally vesting based on continued service through the end of the year preceding the year in which payment of the award is made. There was a payment made in 2015 and the
Long Term Incentive Cash Plan has been terminated and no other payments will be made under this plan. In addition, there is no other cash plan currently in effect.

Constellium N.V. 2013 Equity Incentive Plan

The Company adopted the Constellium N.V. 2013 Equity Incentive Plan (the Constellium 2013 Equity Plan). The principal purposes of
this plan are to focus directors, officers and other employees and consultants on business performance that creates shareholder value, to encourage innovative approaches to the business of the Company and to encourage ownership of our ordinary
shares by directors, officers and other employees and consultants.

The Constellium 2013 Equity Plan provides for a variety of awards,
including incentive stock options (within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the Code)) (ISOs), nonqualified stock options, stock appreciation rights
(SARs), restricted stock, restricted stock units, performance units, other stock-based awards or any combination of those awards. The Constellium 2013 Equity Plan provides that awards may be made under the plan for ten years. We have
reserved 7,292,291 ordinary shares for issuance under the Constellium 2013 Equity Plan, subject to adjustment in certain circumstances to prevent dilution or enlargement.

Administration

The Constellium 2013 Equity Plan is administered by our remuneration committee. The board of directors or the remuneration committee may
delegate administration to one or more members of our board of directors. The remuneration committee has the power to interpret the Constellium 2013 Equity Plan and to adopt rules for the administration, interpretation and application of the
Constellium 2013 Equity Plan according to its terms. The remuneration committee determines the number of our ordinary shares that will be subject to each award granted under the Constellium 2013 Equity Plan and may take into account the
recommendations of our senior management in determining the award recipients and the terms and conditions of such awards. Subject to certain exceptions as may be required pursuant to Rule 16b-3 under the Exchange Act, if applicable, our board of
directors may at any time and from time to time exercise any and all rights and duties of the remuneration committee under the Constellium 2013 Equity Plan.

Eligibility

Certain directors, officers, employees and consultants are eligible to be granted awards under the Constellium 2013 Equity Plan. Our
remuneration committee determines:

| |  |  | the terms and conditions of such awards, consistent with the Constellium 2013 Equity Plan.
| | - |  | ------------------------------------------------------------------------------------------

Our remuneration committee has the discretion, subject to the limitations of the Constellium 2013 Equity Plan and applicable laws, to grant
stock options, SARs and rights to acquire restricted stock (except that only our employees may be granted ISOs).

Stock Options

Subject to the terms and provisions of the Constellium 2013 Equity Plan, stock options to purchase our ordinary shares may be
granted to eligible individuals at any time and from time to time as determined by our remuneration committee. Stock options may be granted as ISOs, which are intended to qualify for favorable treatment to the recipient under U.S. federal tax law,
or as nonqualified stock options, which do not qualify for this favorable tax treatment. Subject to the limits provided in the Constellium 2013 Equity Plan, our remuneration committee has the authority to determine the number of stock options
granted to each recipient. Each stock option grant is evidenced by a stock option agreement that specifies the stock option exercise price, whether the stock options are intended to be incentive stock options or nonqualified stock options, the
duration of the stock options, the number of shares to which the stock options pertain and such additional limitations, terms and conditions as our remuneration committee may determine.

Our remuneration committee determines the exercise price for each stock option granted, except that the stock option exercise price may not be
less than 100% of the fair market value of an ordinary share on the date of grant. All stock options granted under the Constellium 2013 Equity Plan expire no later than ten years from the date of grant. Stock options are nontransferable except by
will or by the laws of descent and distribution or, in the case of nonqualified stock options, as otherwise expressly permitted by our remuneration committee. The granting of a stock option does not accord the recipient the rights of a shareholder,
and such rights accrue only after the exercise of a stock option and the registration of ordinary shares in the recipients name.

Stock Appreciation Rights

Our remuneration committee in its discretion may grant SARs under the Constellium 2013 Equity Plan. SARs may be tandem SARs, which
are granted in conjunction with a stock option, or free-standing SARs, which are not granted in conjunction with a stock option. A SAR entitles the holder to receive from us, upon exercise, an amount equal to the excess, if any, of the
aggregate fair market value of a specified number of our ordinary shares to which such SAR pertains over the aggregate exercise price for the underlying shares. The exercise price of a free-standing SAR may not be less than 100% of the fair market
value of an ordinary share on the date of grant.

A tandem SAR may be granted at the grant date of the related stock option. A tandem SAR
may be exercised only at such time or times and to the extent that the related stock option is exercisable and has the same exercise price as the related stock option. A tandem SAR terminates or is forfeited upon the exercise or forfeiture of the
related stock option, and the related stock option terminates or is forfeited upon the exercise or forfeiture of the tandem SAR.

Each SAR
is evidenced by an award agreement that specifies the exercise price, the number of ordinary shares to which the SAR pertains and such additional limitations, terms and conditions as our remuneration committee may determine. We may make payment of
the amount to which the participant exercising the SARs is entitled by delivering ordinary shares, cash or a combination of stock and cash as set forth in the award agreement relating to the SARs. SARs are not transferable except by will or the laws
of descent and distribution or, with respect to SARs that are not granted in tandem with a stock option, as expressly permitted by our remuneration committee.

##### Table of Contents

Restricted Stock

The Constellium 2013 Equity Plan provides for the award of ordinary shares that are subject to forfeiture and restrictions on transferability
to the extent permitted by applicable law and as set forth in the Constellium 2013 Equity Plan, the applicable award agreement and as may be otherwise determined by our remuneration committee. Except for these restrictions and any others imposed by
our remuneration committee to the extent permitted by applicable law, upon the grant of restricted stock, the recipient will have rights of a shareholder with respect to the restricted stock, including the right to vote the restricted stock and to
receive all dividends and other distributions paid or made with respect to the restricted stock on such terms as set forth in the applicable award agreement. During the restriction period set by our remuneration committee, the recipient is
prohibited from selling, transferring, pledging, exchanging or otherwise encumbering the restricted stock to the extent permitted by applicable law.

Restricted Stock Units

The Constellium 2013 Equity Plan authorizes our remuneration committee to grant restricted stock units. Restricted stock units are not ordinary
shares and do not entitle the recipient to the rights of a shareholder, although the award agreement may provide for rights with respect to dividend equivalents. The recipient may not sell, transfer, pledge or otherwise encumber restricted stock
units granted under the Constellium 2013 Equity Plan prior to their vesting. Restricted stock units may be settled in cash, ordinary shares or a combination thereof as provided in the applicable award agreement, in an amount based on the fair market
value of an ordinary share on the settlement date.

Performance Units

The Constellium 2013 Equity Plan provides for the award of performance units that are valued by reference to a designated amount of cash or to
property other than ordinary shares. The payment of the value of a performance unit is conditioned upon the achievement of performance goals set by our remuneration committee in granting the performance unit and may be paid in cash, ordinary shares,
other property or a combination thereof. Any terms relating to the termination of a participants employment will be set forth in the applicable award agreement.

Other Stock-Based Awards

The Constellium 2013 Equity Plan also provides for the award of ordinary shares and other awards that are valued by reference to our ordinary
shares, including unrestricted stock, dividend equivalents and convertible debentures.

Performance Goals

The Constellium 2013 Equity Plan provides that performance goals may be established by our remuneration committee in connection with the grant
of any award under the Constellium 2013 Equity Plan.

Termination without Cause Following a Change in Control

Upon a termination of employment of a plan participant occurring upon or during the two years immediately following the date of a change
in control (as defined in the Constellium 2013 Equity Plan) by the Company without cause (as defined in the Constellium 2013 Equity Plan), unless otherwise provided in the applicable award agreement, (i) all awards held by
such participant will vest in full (in the case of any awards that are subject to performance goals, at target) and be free of restrictions, and (ii) any option or SAR held by the participant as of the date of the change in control that remains
outstanding as of the date of such termination of employment may thereafter be exercised until (A) in the case of ISOs, the last date on which such ISOs would otherwise be exercisable or (B) in the case of nonqualified options and SARs,
the later of (x) the last date on which such nonqualified option or SAR would otherwise be exercisable and (y) the earlier of (I) the second anniversary of such change in control and (II) the expiration of the term of such
nonqualified option or SAR.

##### Table of Contents

Amendments

Our board of directors or our remuneration committee may amend, alter or discontinue the Constellium 2013 Equity Plan, but no amendment,
alteration or discontinuation will be made that would materially impair the rights of a participant with respect to a previously granted award without such participants consent, unless such an amendment is made to comply with applicable law,
including, without limitation, Section 409A of the Code, stock exchange rules or accounting rules. In addition, no such amendment will be made without the approval of the Companys shareholders to the extent such approval is required by
applicable law or the listing standards of the applicable stock exchange.

Free Share Program

In connection with our IPO, our remuneration committee approved a free share program for all employees (other than short-term employees)
situated in the United States, France, Germany, Switzerland, and the Czech Republic. Under this program, each eligible employee received an award of 25 restricted stock units under the Constellium 2013 Equity Plan in May 2013 that have vested and
have been settled in ordinary shares on the second anniversary of our IPO, i.e., in May 2015 for those employees still employed by the Company or its subsidiaries through that date.

Shareholding Retention Program

In
October 2013, our remuneration committee approved a shareholding retention program to encourage critical members of our senior management team to maintain a significant portion of their current investment under the Companys Management Equity
Plan (the MEP) (which it has now been resolved, with effect as of November 10, 2015, to wind up; further described in Management Equity Plan). Pursuant to this program, certain members of our senior management team
were awarded a one-time retention award under the Constellium 2013 Equity Plan consisting of a grant of restricted stock units with a grant date value equal to a specified percentage of the recipients annual base salary. The restricted stock
units will vest and be settled for our ordinary shares on the second anniversary of the date of grant, subject to the recipient remaining continuously employed with the Company through that date, and for any recipient who was an MEP participant,
subject to his or her retaining, prior to the wind-up of the MEP, at least 75% of his or her interest in our ordinary shares under the MEP (including any interest in ordinary shares that becomes vested following the date of grant), and his or her
compliance with the protocol to be established by the Company for the orderly liquidation of shares held in the MEP.

Co-investment Award Program

Also in October 2013, our remuneration committee approved a co-investment award program for certain critical members of our senior
management team for 2014. Each participant in this program was given the opportunity to invest in our ordinary shares, between 30% and 50% of the gross annual bonus he or she earns under the EPA in respect of 2013. Participants who opted to invest
under this program will be granted performance-based restricted stock units under the Constellium 2013 Equity Plan (performance RSUs) in an amount equal to a specified multiple of the ordinary shares invested. The performance RSUs will

through that date, his or her retaining at least 75% of his or her interest in our ordinary shares under the MEP (including any interest in ordinary shares that becomes vested following the date of grant), if applicable, and 100% of his or her
investment under this program, and his or her compliance with the protocol to be established by the Company for the orderly liquidation of shares held in the MEP, if applicable.

Employment and Service Arrangements

We
are party to employment or services agreements with each of our officers. We may terminate certain officers employment with or services to us for cause upon advance written notice, without compensation, for



-93-

##### Table of Contents

certain acts of the officer. Each officer may terminate his or her employment at any time upon advance written notice to us. In the event that the officers employment or service is
terminated by us without cause or, in the case of certain executives, by him for good reason, the officer is entitled to certain payments as provided by applicable laws or collective bargaining agreements or as otherwise provided under
the applicable employment or services agreements. Except for the foregoing, our officers are not entitled to any severance payments upon the termination of their employment or services for any reason.

Under such employment and services agreements, each of our officers has also agreed not to engage or participate in any business activities
that compete with us or solicit our employees or customers for (depending on the officer) up to two years after the termination of his employment or services. They have further agreed not to use or disseminate any confidential information concerning
us as a result of performing their duties or using our resources during their employment with or services to us.



|C. | Board Practices
|-- | ---------------

Our board of directors (the Board) currently consists of
nine directors, less than a majority of whom are citizens or residents of the United States.

We currently have a one-tier Board
consisting of one Executive Director and eight Non-Executive Directors (each, a Director). Under Dutch law, the Board is responsible for our policy making and day-to-day management. The Non-Executive Directors supervise and provide
guidance to the Executive director. Each Director owes a duty to us to properly perform the duties assigned to him and to act in our corporate interest. Under Dutch law, the corporate interest extends to the interests of all corporate stakeholders,
such as shareholders, creditors, employees, customers and suppliers.

The Management and Supervision Act (Wet bestuur en
toezicht), effective as of January 1, 2013, strives for a balanced composition of management and supervisory boards of large companies, such as Constellium, to the effect that at least 30% of the positions on the management and
supervisory boards of such companies are held by women and at least 30% by men. There is no legal sanction if the composition of such companys board is not balanced in accordance with the Act. An appointment contrary to these rules will
therefore not be null and void. However, in such case, the company must explain any noncompliance with the 30% criteria in its annual report. The explanation must include the reasons for noncompliance and the actions the company intends to take in
order to comply in the future. These rules have expired on January 1, 2016. New rules with respect to this may be introduced in the near future.

Our Articles of Association provide that our shareholders acting at a general meeting (a General Meeting) appoint directors upon a
binding nomination by the Board. The General Meeting may at all times overrule the binding nature of such nomination by a resolution adopted by a majority of at least two-thirds of the votes cast, provided that such majority represents more than 50%
of our issued share capital. If the binding nomination is overruled, the Non-Executive Directors may then make a new nomination. If such a nomination has not been made or has not been made in time, this shall be stated in the notice and the General
Meeting shall be free to appoint a director in its discretion. Such a resolution of the General Meeting must be adopted by at least two-thirds of the votes cast, provided that such majority represents more than 50% of our issued share capital.

The Directors may be suspended or dismissed at any time by the General Meeting. A resolution to suspend or dismiss a Director must be adopted
by at least two-thirds of the votes cast, provided that such majority represents more than 50% of our issued share capital. If, however, the proposal to suspend or dismiss the Directors is made by the Board, the proposal must be adopted by simple
majority of the votes cast at the General Meeting. The Executive Director can at all times be suspended by the Board.

Director
Independence

As a foreign private issuer under the NYSE rules, we are not required to have independent Directors on our Board,
except to the extent that our Audit Committee is required to consist of independent Directors. However,

|D. | Employees
|-- | ---------

As of December 31, 2015, we employed approximately 11,000 permanent
employees of which approximately 85% were engaged in production and maintenance activities and approximately 15% were employed in support functions. Approximately 40% of our employees were employed in France, 17% in Germany, 26% in the United
States, 8% in Switzerland, and 9% in Eastern Europe and other regions. As of December 31, 2015 and 2014, we employed approximately 11,000 and 8,900 employees, respectively.

A vast majority of non-U.S. employees and approximately 49% of U.S. employees are covered by collective bargaining agreements. These
agreements are negotiated on site, regionally or on a national level and are of different durations. Except in connection with prior negotiations completed during the fourth quarter of 2011, around our plan to restructure our plant in Ham, France
(which has since been disposed of), we have not experienced a prolonged labor stoppage in any of our production facilities in the past 10 years.

In addition to our employees, we employed 1,031, 600 and 1,500 temporary employees, respectively, as of December 31, 2013, 2014, and
2015.



|E. | Share Ownership
|-- | ---------------

Information with respect to share ownership of members of our board of
directors and our senior management is included in Item 7. Major Shareholders and Related Party Transactions.

Management Equity Plan

Following the Acquisition, a management equity plan (the MEP) was established effective from February 4, 2011, to
facilitate investments by our officers and other members of management in Constellium. In connection with the MEP, a German limited partnership, Omega Management GmbH & Co. KG (Management KG), was formed. The general partner of
Management KG is Omega MEP GmbH (GP GmbH), a German limited liability company, which is wholly owned by Stichting Management Omega.

Management KG is a vehicle which has allowed current and former directors, officers and employees of Constellium who invested in the MEP
(either directly or indirectly through one or more investment vehicles) (the MEP Participants) to hold a limited partnership interest in Management KG that corresponded to a portion of the shares in Constellium held by Management KG.
Certain of our executive officers, including our Chief Executive Officer, Mr. Vareille, and our Chief Financial Officer, Mr. Fontaine, each participated in the MEP. In connection with our IPO, the MEP was frozen and no other employees,
officers or directors of Constellium were invited to become MEP Participants. Any future equity incentive awards were to be granted under the Constellium 2013 Equity Plan.

Following the advisory board resolution of GP GmbH dated November 6, 2015, it was resolved to wind-up the MEP, which is expected to be
finalized in the course of 2016. In connection with the wind-up of the MEP, the respective shares held through the MEP were distributed to former MEP Participants in the amount of their corresponding investments and awards under the program. The
shares distributed in connection with the previous investment of Mr. Vareille represented 972,080 Class A ordinary shares; and the shares distributed in connection with the previous MEP investment of Mr. Fontaine represented 131,985
Class A ordinary shares. In connection with the wind-up of the MEP and with effect as of November 10, 2015, 2,410,357 Class A ordinary shares were transferred to the 34 MEP Participants in accordance with their respective share
allocations under the MEP.

##### Table of Contents

Management KG no longer holds any shares in Constellium and the limited partnership
interests no longer represent an indirect economical interest in Constellium; it is therefore intended to terminate the Management KG (the Termination). Pursuant to an advisory board resolution of GP GmbH dated November 6, 2015, the
Termination involves the following main steps: (a) the transfer by each of the remaining registered limitedpartners of their respective limited partnership interests to Stichting Management Omega and thereafter (b) the entry into a
withdrawal agreement between GP GmbH and Stichting Management Omega, whereby GP GmbH shall withdraw from, and thus cease to be a partner in, Management KG, leaving Stichting Management Omega to assume all of Management KGs residual assets and
liabilities by way of universal succession (Gesamtrechtsnachfolge) without liquidation by way of accretion (Anwachsung). Following the Termination, the processes for liquidating GP GmbH and Stichting Management Omega will be
implemented.

Equity Incentive Plan

The Company adopted the Constellium 2013 Equity Plan under which certain of our directors, officers, employees, and consultants are eligible to
receive equity awards. See Constellium N.V. 2013 Equity Incentive Plan above.

Item 7.
Major Shareholders and Related Party Transactions



|A. | Major Shareholders
|-- | ------------------

The following table sets forth the principal shareholders of
Constellium N.V. (each person or group of affiliated persons who is known to be the beneficial owner of more than 5% of ordinary shares) and the number and percentage of ordinary shares owned by each such shareholder, in each case as of April 18,
2016.

Under the rules of the SEC, a person is deemed to be a beneficial owner of a security if that person has or shares
voting power, which includes the power to vote or to direct the voting of such security, or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be
a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Under these rules, more than one person may be deemed to be a beneficial owner of such securities as to which such person has
voting or investment power.

The beneficial ownership percentages in this table have been calculated on the basis of the total number of
Class A ordinary shares.

None of our principal
shareholders have voting rights different from those of our other shareholders.

Over the last three years, the only significant changes
of which we have been notified in the percentage ownership of our shares by our major shareholders described above were that prior to the IPO, immediately following the completion of the purchase of the EAP Business: Apollo Funds held 51% of our
Class A ordinary shares, Rio Tinto held 39% of our Class A ordinary shares, and Bpifrance (f/k/a FSI) held 10% of our Class A ordinary shares. As of the date of this Annual Report, Apollo Funds holds 0% of our Class A ordinary
shares, Rio Tinto holds ten shares of our Class A ordinary shares and Bpifrance holds 12.2% of our class A ordinary shares, respectively. See Item 4. Information on the CompanyA. History and Development of the Company.



|B. | Related Party Transactions

Pre-IPO Shareholders Agreement

In connection with the Acquisition, Apollo Omega, Rio Tinto, Bpifrance and the other parties thereto entered into a pre-IPO Shareholders
Agreement, dated as of January 4, 2011 (the Pre-IPO Shareholders Agreement). The Pre-IPO Shareholders Agreement provided for, among other items, certain restrictions on the transferability of equity ownership in Constellium as well
as certain tag-along rights, drag-along rights, and piggy-back registration rights. We amended and restated the Pre-IPO Shareholders Agreement in connection with the IPO. See Amended and Restated Shareholders Agreement below.

Amended and Restated Shareholders Agreement

The Company, Apollo Omega, Rio Tinto and Bpifrance entered into an amended and restated shareholders agreement on May 29, 2013 (the
Shareholders Agreement). The Shareholders Agreement terminated with respect to Apollo Omega and Rio Tinto in connection with certain of their respective sales of our ordinary shares described elsewhere in this Annual Report. The
Shareholders Agreement provides for, among other things, piggyback registration rights and demand registration rights for Bpifrance for so long as Bpifrance owns any of our ordinary shares.

In addition, the Shareholders Agreement provides that, except as otherwise required by applicable law, Bpifrance will be entitled to designate
for binding nomination one director to our board of directors so long as its percentage ownership interest is equal to or greater than 4% or it continues to hold all of the ordinary shares it

subscribed for at the closing of the Acquisition (such share number adjusted for the pro rata share issuance). Our directors will be elected by our shareholders acting at a general meeting upon a
binding nomination by the board of directors as described in Item 6. Directors, Senior Management and EmployeesA. Directors and Senior Management. A shareholders percentage ownership interest is derived by dividing
(i) the total number of ordinary shares owned by such shareholder and its affiliates by (ii) the total number of outstanding ordinary shares.

The Company has agreed to share financial and other information with Bpifrance to the extent reasonably required to comply with its tax,
investor or regulatory obligations and with a view to keeping Bpifrance properly informed about the financial and business affairs of the Company. The Shareholders Agreement contains provisions to the effect that Bpifrance is obliged to treat all
information provided to it as confidential, and to comply with all applicable rules and regulations in relation to the use and disclosure of such information.

Management Equity Plan

Investments by
our officers and directors in Constellium were facilitated by their participation in a management equity plan (the MEP), Management KG (a German limited partnership), which subscribed for Class A and Class B ordinary shares in
Constellium. With effect as of November 6, 2015, it was resolved to wind up the MEP and terminate Management KG (further described in Management Equity Plan). With effect as of November 6, 2015, it has been resolved to
wind up the MEP and terminate Management KG.

Stichting Reacquisition

Prior to our IPO, Rio Tinto, Apollo Omega, Bpifrance, Constellium and Stichting Management Omega had entered into an agreement (the
Funding Agreement), effective as of July 1, 2011, that provided that limited partnership interests in Management KG held by Stichting Management Omega would be so held for the pro rata benefit and risk of Rio Tinto, Apollo Omega,
and Bpifrance. In connection with the freezing of the MEP, our board of directors approved the reacquisition and our shareholders approved the cancellation of all Class A ordinary shares and Class B2 ordinary shares attributable to the
Management KG interests held by Stichting Management Omega, and all such shares were reacquired by us prior to the completion of the IPO for an acquisition amount of approximately 900,000. As a result of this reacquisition, the Management KG
interests held by Stichting Management Omega ceased to have economic value, and Stichting Management Omega ceased to be an indirect owner of our ordinary shares. In connection with the IPO, the Funding Agreement was amended to provide that any
limited partnership interests in Management KG acquired by Stichting Management Omega following the completion of the IPO will be held for the benefit of Constellium. In connection with the winding up of the MEP, Management KG will be terminated and
Stichting Management Omega, which does not own any shares in Constellium, liquidated (further described in Management Equity Plan).

Share Sales by Management KG

During
November 2013, limited partners of Management KG (other than the limited partners who were former employees of Constellium or who were to imminently become former employees of Constellium) were offered the opportunity to participate in trading plans
to be established by Management KG under Rule 10b5-1 promulgated under the Exchange Act (the MEP Trading Plans) for the orderly liquidation of shares held in the MEP. The first such plan was established on December 13, 2013 and a
total of 30 limited partners elected to participate in such plan, which commenced trading on January 13, 2014. A second such trading plan was established on June 13, 2014 and a total of 33 limited partners elected to participate in such
plan, which commenced trading on July 14, 2014. As of December 31, 2015, all Class A ordinary shares have been sold pursuant to the MEP Trading Plans.

Legal Proceedings

Dividend Policy

Our board of directors periodically explores the potential adoption of a dividend program; however, no assurances can be made that any future
dividends will be paid on the ordinary shares. Any declaration and payment of future dividends to holders of our ordinary shares will be at the discretion of our board of directors and will depend on many factors, including our financial condition,
earnings, capital requirements, level of indebtedness, statutory future prospects and contractual restrictions applying to the payment of dividends and other considerations that our board of directors deems relevant. In general, any payment of
dividends must be made in accordance with our Amended and Restated Articles of Association and the requirements of Dutch law. Under Dutch law, payment of dividends and other distributions to shareholders may be made only if our shareholders
equity exceeds the sum of our called up and paid-in share capital plus the reserves required to be maintained by law and by our Amended and Restated Articles of Association.

Generally, we rely on dividends paid to Constellium N.V., or funds otherwise distributed or advanced to Constellium N.V. by its subsidiaries
to fund the payment of dividends, if any, to our shareholders. In addition, restrictions contained in the agreements governing our outstanding indebtedness limit our ability to pay dividends on our ordinary shares and limit the ability of our
subsidiaries to pay dividends to us. Future indebtedness that we may incur may contain similar restrictions.



|B. | Significant Changes
|-- | -------------------

On March 30, 2016, the Company completed a private offering of
$425 million in aggregate principal amount of Senior Secured Notes pursuant to an indenture among the Company, the guarantors party thereto, and Deutsche Bank Trust Company Americas, as trustee and collateral agent. The Company invested
100 million of the net proceeds in Wise. We used the remaining net proceeds for general corporate purposes, including to put additional cash on our balance sheet. Interest on the Senior Secured Notes accrues at a rate of 7.875% per
annum and is payable semi-annually beginning October 1, 2016. The Senior Secured Notes mature on April 1, 2021. See Item 10. Additional InformationC. Material ContractsMarch 2016 Senior Secured Notes.

The Guarantor Coverage Test requires, on any one

Secured Notes, taken together, represent not less than 80% of the EBITDA of the Company and its restricted subsidiaries (excluding Wise Intermediate Holdings LLC and its direct and indirect subsidiaries until such time as the restrictive covenants

the Senior Secured Notes and the guarantees thereof are required to be first-priority, provided that (x) the liens on the Ravenswood ABL Priority Collateral (as defined below) securing the Senior Secured Notes and the guarantees thereof are
required to be junior in priority to the liens on the Ravenswood ABL Priority Collateral securing the obligations under the Ravenswood ABL Facility, and (y) the liens on certain property of Ravenswood (the PBGC Priority Collateral)
securing the Senior Secured Notes and the guarantees thereof are required to be junior in priority to the liens on such property securing certain obligations of Ravenswood to the Pension Benefit Guaranty Corporation (the PBGC).The

reasonable efforts to have all such security interests created and perfected until such time, if any, as the Company determines that any further efforts would be futile. The liens on the PBGC Priority Collateral securing the Senior Secured Notes and
the guarantees thereof will not be created unless and until the PBGC gives its reasonable consent and enters into an intercreditor agreement with the collateral agent for the Senior Secured Notes. To the extent that a lien and mortgage on the
property, plant and equipment of our Ravenswood facility is not provided to secure the Senior Secured Notes with the priority required under the indenture and security documents governing the Senior Secured Notes (the Collateral
Condition) on or prior to the date that is 90 days following the issue date, the Senior Secured Notes will accrue additional interest at a rate of 2.00% per annum from such 90th day
following the issue date until (i) if the Collateral Condition is satisfied on or prior to the date that is 360 days following the issue date, the date the Collateral Condition is satisfied, or (ii) if the Collateral Condition is not
satisfied on or prior to the date that is 360 days following the issue date, the date interest on the Senior Secured Notes is no longer payable in accordance with the terms of the indenture.

Unsecured Revolving Credit Facility

On
May 7, 2014, the Company entered into a new senior unsecured revolving credit facility (the Unsecured Revolving Credit Facility) pursuant to a credit agreement among the Company, as borrower, the lenders from time to time party
thereto and Deutsche Bank AG New York Branch, as administrative agent. The Company amended the Unsecured Revolving Credit Facility on December 5, 2014, February 5, 2015, September 30, 2015, and December 10, 2015 to,
among other things, increase the total commitments and extend the maturity date thereunder, permit the consummation of the Wise Acquisition without Wise guaranteeing the obligations thereunder, permit the Wise ABL Facility to remain outstanding in
an amount of up to $450 million following the consummation of the Wise Acquisition, and amend certain financial covenants thereunder. As amended, the Unsecured Revolving Credit Facility provided for total commitments of up to 145 million,
with a maturity date of January 5, 2018.

Interest under the Unsecured Revolving Credit Facility was calculated based on the adjusted
eurocurrency rate plus 2.50% per annum.

In addition to paying interest on outstanding loans under the Unsecured Revolving Credit
Facility, we were required to pay (a) commitment fees equal to 1.00% per annum times the undrawn portion of the commitments under the facility and (b) utilization fees equal to (i) if the daily average drawn portion of the
commitments under the facility (the Drawn Amount) was less than 50.0% of the aggregate commitments, 0.25% per annum times the Drawn Amount or (ii) if the Drawn Amount was greater than or equal to 50.0% of the aggregate
commitments, 0.50% per annum times the Drawn Amount.

Subject to customary breakage costs, borrowings under the Unsecured
Revolving Credit Facility were permitted to be repaid from time to time without premium or penalty.

Our obligations under the Unsecured
Revolving Credit Facility were guaranteed by Constellium Holdco II B.V., Constellium France Holdco S.A.S., Constellium Issoire S.A.S., Constellium Neuf Brisach S.A.S., Constellium Finance S.A.S., Constellium Germany Holdco GmbH & Co. KG,
Constellium Deutschland GmbH, Constellium Singen GmbH, Constellium Switzerland AG, Constellium US Holdings I, LLC, and Constellium Rolled Products Ravenswood, LLC. None of Wise or its direct or indirect subsidiaries guaranteed our obligations under
the Unsecured Revolving Credit Facility.

The Unsecured Revolving Credit Facility contained customary terms and conditions, including,
among other things, negative covenants limiting our and our restricted subsidiaries ability to incur debt, grant liens, enter into sale and lease-back transactions, make investments, loans and advances, make acquisitions, sell assets, pay
dividends and other restricted payments, prepay certain debt, merge, consolidate or amalgamate and engage in affiliate transactions.

In
addition, at any time that loans were (a) borrowed, to the extent that immediately after giving effect to such borrowing, loans in excess of 30% of the total commitments under the Unsecured Revolving Credit Facility would be outstanding, or
(b) outstanding on the last day of our fiscal quarter, the Unsecured Revolving Credit Facility required us to (x) maintain a consolidated total net leverage ratio of no more than (1) in the case of each

of the first four fiscal quarters ending after October 1, 2015, 5.00 to 1.00, and (2) in the case of each other fiscal quarter, 4.50 to 1.00, (y) maintain a minimum fixed charge
coverage ratio of not less than (1) in the case of each of the first four fiscal quarters ending after October 1, 2015, 2.00 to 1.00, and (2) in the case of each other fiscal quarter, 2.20 to 1.00, and (z) ensure that, taken
together, the Company and the guarantors of the Unsecured Revolving Credit Facility had (i) assets representing not less than 60% of the consolidated total assets of the Company and its subsidiaries and (ii) EBITDA representing not less
than 75% of the consolidated EBITDA of the Company and its subsidiaries (the requirement in the foregoing clause (z), the Guarantor Coverage Test). Wise and its subsidiaries were excluded from the calculation of the Guarantor Coverage
Test. The Unsecured Revolving Credit Facility also contained customary events of default.

On March 30, 2016, concurrently with the
issuance of the Senior Secured Notes, the Unsecured Revolving Credit Facility was terminated.

Ravenswood ABL Facility

On May 25, 2012, Ravenswood entered into a $100 million asset-based revolving credit facility (the Ravenswood ABL Facility),
with the lenders from time to time party thereto and Deutsche Bank Trust Company Americas, as administrative agent (the Ravenswood ABL Administrative Agent) and collateral agent. Ravenswood amended the Ravenswood ABL Facility on
October 1, 2013 to, among other things, extend the maturity to October 2018 and reduce pricing. As amended, the Ravenswood ABL Facility has sublimits of $25 million for letters of credit and 10% of the revolving credit facility commitments for
swingline loans. The Ravenswood ABL Facility provides Ravenswood a working capital facility for its operations.

Ravenswoods ability
to borrow under the Ravenswood ABL Facility is limited to a borrowing base equal to the sum of (a) 85% of eligible accounts receivable plus (b) up to the lesser of (i) 80% of the lesser of cost or market value of eligible inventory
and (ii) 85% of the net orderly liquidation value of eligible inventory minus (c) applicable reserves, and is subject to other conditions, limitations and reserve requirements.

Interest under the Ravenswood ABL Facility is calculated, at Ravenswoods election, based on either the LIBOR or base rate (as calculated
by the Ravenswood ABL Administrative Agent in accordance with the Ravenswood ABL Facility). LIBOR loans accrue interest at a rate of LIBOR plus a margin of 1.50-2.00% per annum (determined based on average quarterly excess availability). Base
rate loans accrue interest at the base rate plus a margin of 0.50-1.00% per annum (determined based on average quarterly excess availability). Ravenswood is required to pay a commitment fee on the unused portion of the Ravenswood ABL Facility
of 0.25% or 0.375% per annum (determined on a ratio of unutilized revolving credit commitments to available revolving credit commitments).

Subject to customary breakage costs with respect to LIBOR loans, borrowings under the Ravenswood ABL Facility may be repaid from
time to time without premium or penalty.

Ravenswoods obligations under the Ravenswood ABL Facility are guaranteed by Constellium
U.S. Holdings I, LLC and Constellium Holdco II B.V. (Holdco II). Ravenswoods obligations under the Ravenswood ABL Facility are not guaranteed by the Company, Wise Intermediate Holdings LLC or any of its subsidiaries or any of
Holdco IIs subsidiaries organized outside of the United States. Ravenswoods obligations under the Ravenswood ABL Facility are, subject to certain permitted liens, secured on a first priority basis by substantially all assets of
Ravenswood. Ravenswoods obligations under the Ravenswood ABL Facility are not secured by any assets of Wise Intermediate Holdings LLC or any of its subsidiaries or the Company or any of its subsidiaries organized outside of the United States.
The guarantee by Holdco II of the Ravenswood ABL Facility is unsecured.

The Ravenswood ABL Facility contains customary terms and
conditions, including, among other things, negative covenants limiting Ravenswoods ability to incur debt, grant liens, enter into sale and lease-back

transactions, make investments, loans and advances (including to other Constellium group companies), make acquisitions, sell assets, pay dividends and other restricted payments, prepay certain
debt, merge, consolidate or amalgamate and engage in affiliate transactions. The negative covenants contained in the Ravenswood ABL Facility do not apply to Wise Intermediate Holdings LLC or any of its subsidiaries or the Company or any of its
subsidiaries organized outside of the United States.

The Ravenswood ABL Facility also contains a minimum availability covenant that
requires Ravenswood to maintain excess availability under the Ravenswood ABL Facility of at least the greater of (a) $10 million and (b) 10% of the aggregate revolving loan commitments.

The Ravenswood ABL Facility also contains customary events of default.

European Factoring Agreements

On
January 4, 2011, certain of our French subsidiaries (the French Sellers) entered into a factoring agreement with GE Factofrance S.A.S., as factor (the French Factor), which has been amended from time to time, and has
been fully restated on December 3, 2015 (the French Factoring Agreement). On December 16, 2010, certain of our German and Swiss subsidiaries (the German/Swiss Sellers) entered into factoring agreements with GE
Capital Bank AG, as factor (the German/Swiss Factor), which have been amended from time to time or replaced with a factoring agreement entered into on March 26, 2014 (the German/Swiss Factoring Agreements). On
June 26, 2015, our Czech subsidiary (the Czech Seller, and together with the German/Swiss Sellers and the French Sellers, the European Factoring Sellers) entered into a factoring agreement with GE Capital Bank AG, as
factor (the Czech Factor, and together with the German/Swiss Factor and the French Factor, the European Factors), as amended from time to time (the Czech Factoring Agreement, and together with the German/Swiss
Factoring Agreements and the French Factoring Agreement, the European Factoring Agreements).

The European Factoring
Agreements provide for the sale by the European Factoring Sellers to the European Factors of receivables originated by the European Factoring Sellers, subject to a maximum financing amount of 235 million available to the French Sellers
under the French Factoring Agreement and 115 million available to the German/Swiss Sellers and the Czech Seller under the German/Swiss Factoring Agreements and the Czech Factoring Agreement, respectively. The German/ Swiss Factoring
Agreements have a termination date of June 4, 2017. The French Factoring Agreement has a termination date of December 31, 2018. The funding made available to the European Factoring Sellers by the European Factors is used by the Sellers for
general corporate purposes.

Generally speaking, receivables sold to the European Factors under the European Factoring Agreements are with
no recourse to the European Factoring Sellers in the event of a payment default by the relevant customer. The European Factors are entitled to claim the repayment of any amount financed by them in respect of a receivable by withdrawing the financing
provided against such assigned receivable or requiring the European Factoring Sellers to repurchase/unwind the purchase of such receivable under certain circumstances, including when (i) the non-payment of that receivable arises from a dispute
between a European Factoring Seller and the relevant customer or (ii) the receivable proves not to have satisfied the eligibility criteria set forth in the European Factoring Agreements.

The German/Swiss Factoring Agreements and the Czech Factoring Agreement are without recourse to the German/Swiss Sellers and the Czech Seller,
respectively, for any credit risk resulting from the inability of a debtor to meet its payment obligations under the receivables sold to the German/Swiss Factor, respectively the Czech Factor. Constellium Holdco II B.V. has provided a performance
guaranty for the Sellers obligations under the European Factoring Agreements.

Subject to some exceptions, the European Factoring
Sellers will collect the transferred receivables on behalf of the European Factors pursuant to a receivables collection mandate under the European Factoring Agreements.



-112-

##### Table of Contents

The receivables collection mandate may be terminated upon the occurrence of certain events. In the event that the receivables collection mandate is terminated, the European Factors will be
entitled to notify the account debtors of the assignment of receivables and collect directly from the account debtors the assigned receivables.

The European Factoring Agreements contain customary fees, including (i) a financing fee on the outstanding amount financed in respect of
the assigned receivables, (ii) a non-utilization fee on the portion of the facilities not utilized by the European Factors and (iii) a factoring fee on all assigned receivables in the case of the German/Swiss Factoring Agreements and sold
receivables, which were approved by the French Factor in the case of the French Factoring Agreement. In addition, the European Factoring Sellers incur the cost of maintaining the necessary credit insurance (as stipulated in the European Factoring
Agreements) on assigned receivables.

The European Factoring Agreements contain certain affirmative and negative covenants, including
relating to the administration and collection of the assigned receivables, the terms of the invoices and the exchange of information, but do not contain restrictive financial covenants. As of and for the fiscal quarter ended December 31, 2015,
the European Factoring Sellers were in compliance with all applicable covenants under the European Factoring Agreements.

On December 11,
2013, Wise Alloys LLC, as borrower, and Wise Metals Group LLC, Listerhill Total Maintenance Center, LLC (TMC), Wise Alloys Finance Corporation, and Alabama Electric Motor Services, LLC (AEM), as guarantors, entered into a
$320 million asset-based revolving credit facility (as amended, the Wise ABL Facility) with the lenders from time to time party thereto and General Electric Capital Corporation as administrative agent (the Wise ABL Facility
Agent). As described below, the Wise ABL Facility was amended in connection with the Wise Acquisition and in connection with the Wise RPA.

Wise Alloys LLC has the option to increase the commitments under the Wise ABL Facility from time to time by up to $100 million in the
aggregate for all such increases. Any increase of the commitments under the Wise ABL Facility is subject to the commitment of one or more lenders to such increased amount and the satisfaction of certain customary conditions, including the absence of
any default under the Wise ABL Facility and, to the extent otherwise required under the Wise ABL Facility at the time of the proposed increase, compliance with the financial covenant (as described below) on an as adjusted basis.

Wise Alloys LLCs ability to borrow under the Wise ABL Facility is limited to a borrowing base equal to the sum of (a) 85% of net
book value of Wise Alloys LLCs, AEMs, and TMCs eligible accounts receivable (other than any accounts receivable from certain foreign account debtors (Eligible Foreign Account Debtors) and other ineligible account

the Wise ABL Facility Agents sole discretion after completion of a collateral audit, be increased to an amount not to exceed $5 million) minus (f) the aggregate amount of reserves, if any, established by the Wise ABL Facility Agent. Wise
Alloys LLCs ability to borrow under the Wise ABL Facility is also subject to other conditions and limitations. As of December 31, 2015, there was $25 million available for borrowings under the Wise ABL Facility (as in effect as of that
date).

Interest rates under the Wise ABL Facility are based, at Wise Alloys LLCs election, on either the LIBOR rate or a base rate,
plus a spread that ranges from 1.75% to 2.25% for LIBOR loans and 0.75% to 1.25% for base rate loans. The spread is determined on the basis of a pricing grid that results in a higher spread as Wise Alloys LLCs average quarterly borrowing
availability under the Wise ABL Facility declines, and, in each case, are based upon the borrowing base calculation delivered to the Wise ABL Facility Agent for the last calendar month (or, in certain instances, week) of the immediately preceding
fiscal quarter.

Letters of credit under the Wise ABL Facility are subject to a fee payable to the lenders equal to the current margin
applicable to LIBOR loans multiplied by the daily balance of the undrawn amount of all outstanding letters of credit, payable in cash monthly in arrears.

Unused commitments under the Wise ABL Facility are subject to an unused commitment fee equal to the aggregate amount of such unused
commitments multiplied by a rate equal to 0.375% per annum, payable in cash monthly in arrears, of the average available but unused borrowing capacity under the Wise ABL Facility.

Subject to customary breakage costs with respect to LIBOR loans, borrowings under the Wise ABL Facility may be repaid from time to
time without premium or penalty.

The obligations of Wise Alloys LLC under the Wise ABL Facility are secured by (i) a first priority

as capital assets (generally, property held for investment) under the U.S. Internal Revenue Code of 1986, as amended (the Code). This discussion is based upon existing
U.S. federal income tax law, including the Code, U.S. Treasury regulations thereunder, rulings and court decisions, all of which are subject to differing interpretations or change, possibly with retroactive effect. No ruling from the Internal
Revenue Service (the IRS) has been sought with respect to any U.S. federal income tax consequences described below, and there can be no assurance that the IRS or a court will not take a contrary position.

This discussion does not address all aspects of U.S. federal income taxation that may be relevant to particular investors in light of their
individual circumstances, including investors subject to special tax rules (for example, financial institutions, insurance companies, regulated investment companies, real estate investment trusts, broker-dealers, traders in securities that elect
mark-to-market treatment, partnerships or other pass-through entities for U.S. federal income tax purposes and their partners and investors, tax-exempt organizations (including private foundations), investors who are not U.S. Holders, U.S. Holders
who own (directly, indirectly or constructively) 10% or more of our stock (by vote or value), U.S. Holders that acquire their ordinary shares pursuant to any employee share option or otherwise as compensation, U.S. Holders that hold their ordinary
shares as part of a straddle, hedge, conversion, wash sale, constructive sale or other integrated transaction for U.S. federal income tax purposes or U.S. Holders that have a functional currency other than the U.S. dollar, all of whom may be subject
to tax rules that differ significantly from those summarized below). In addition, this discussion does not discuss any U.S. federal estate, gift or alternative minimum tax consequences, any tax consequences of the Medicare tax on certain investment
income pursuant to the Health Care and Education Reconciliation Act of 2010, or any state, local or non-U.S. tax consequences. Each U.S. Holder is urged to consult its tax advisor regarding the U.S. federal, state, local and non-U.S. income and
other tax considerations of an investment in our ordinary shares.

General

For purposes of this discussion, a U.S. Holder is a beneficial owner of our ordinary shares that is, for U.S. federal income tax
purposes, (i) an individual who is a citizen or resident of the United States, (ii) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created in, or organized under the law of, the United States
or any state thereof or the District of Columbia, (iii) an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source, or (iv) a trust (A) the administration of which is
subject to the primary supervision of a U.S. court and which has one or more U.S. persons who have the authority to control all substantial decisions of the trust or (B) that has otherwise validly elected to be treated as a U.S. person under
the Code.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) is a beneficial
owner of our ordinary shares, the tax treatment of a partner in such partnership will generally depend upon the status of the partner, the activities of the partnership and certain determinations made at the partner level. Partnerships holding our
ordinary shares, and partners in such partnerships, are urged to consult their own tax advisors regarding their investment in our ordinary shares.

Passive Foreign Investment Company Consequences

We believe that we will not be a passive foreign investment company for U.S. federal income tax purposes (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. A foreign corporation will be 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. The determination of whether we are a PFIC is a fact-intensive determination that includes ascertaining the fair market value (or, in



-119-

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, as described above. 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 are a PFIC for any taxable year, U.S. Holders generally will be subject to special tax rules that could result in materially adverse
U.S. federal income tax consequences. In such event, a U.S. Holder may be subject to U.S. federal income tax at the highest applicable ordinary income tax rates on (i) any excess distribution that we make to the U.S. Holder (which
generally means any distribution paid during a taxable year to a U.S. Holder that is greater than 125% of the average annual distributions paid in the three preceding taxable years or, if shorter, the U.S. Holders holding period for the
ordinary shares), or (ii) any gain realized on the disposition of our ordinary shares. In addition, a U.S. Holder may be subject to an interest charge on such tax. Furthermore, the favorable dividend tax rates that may apply to certain U.S.
Holders on our dividends will not apply if we are a PFIC during the taxable year in which such dividend was paid, or the preceding taxable year.

As an alternative to the foregoing rules, if we are a PFIC for any taxable year, a U.S. Holder may make a mark-to-market election with respect
to our ordinary shares, provided that the ordinary shares are regularly traded. Although no assurances may be given, we expect that our ordinary shares should qualify as being regularly traded. If a U.S. Holder makes a valid mark-to-market election,
the U.S. Holder will generally (i) include as ordinary income for each taxable year that we are a PFIC the excess, if any, of the fair market value of our ordinary shares held at the end of the taxable year over the adjusted tax basis of such
ordinary shares and (ii) deduct as an ordinary loss the excess, if any, of the adjusted tax basis of the ordinary shares over the fair market value of such ordinary shares held at the end of the taxable year, but only to the extent of the net
amount previously included in income as a result of the mark-to-market election. The U.S. Holders tax basis in the ordinary shares would be adjusted to reflect any income or loss resulting from the mark-to-market election. Gain on the sale or
other disposition of our ordinary shares would be treated as ordinary income, and loss on the sale or other disposition of our ordinary shares would be treated as an ordinary loss, but only to the extent of the amount previously included in income
as a result of the mark-to-market election. If a U.S. Holder makes a mark-to-market election in respect of a corporation classified as a PFIC and such corporation ceases to be classified as a PFIC, the holder will not be required to take into
account the gain or loss described above during any period that such corporation is not classified as a PFIC. Because a mark-to-market election cannot be made for any lower-tier PFICs that we may own, a U.S. Holder may continue to be subject to the
PFIC rules with respect to such U.S. Holders indirect interest in any investment held by us that is treated as an equity interest in a PFIC for U.S. federal income tax purposes.

Subject to certain limitations, a U.S. Holder may make a qualified electing fund election (QEF election), which serves
as a further alternative to the foregoing rules, with respect to its investment in a PFIC. In order for a U.S. Holder to be able to make a QEF election, we must provide such U.S. Holders with certain information. Because we do not intend to provide
U.S. Holders with the information needed to make such an election, prospective investors should assume that the QEF election will not be available.

Each U.S. Holder is advised to consult its 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, including the possibility of making a mark-to-market election.

The
remainder of the discussion below assumes that we are not a PFIC, have not been a PFIC and will not become a PFIC in the future.

Distributions

The gross amount of distributions with respect to our ordinary shares (including the amount of any non-U.S. withholding taxes)
will be taxable as dividends, to the extent paid out of our current or accumulated earnings and



-120-



---

##### Table of Contents

profits, as determined under U.S. federal income tax principles. Such distributions will be includable in a U.S. Holders gross income as ordinary dividend income on the day actually or
constructively received by the U.S. Holder. Such dividends will not be eligible for the dividends-received deduction allowed to corporations under the Code.

To the extent that the amount of the distribution exceeds our current and accumulated earnings and profits for a taxable year, as determined
under U.S. federal income tax principles, the distribution will be treated first as a tax-free return of capital to the extent of the U.S. Holders tax basis in our ordinary shares, and to the extent the amount of the distribution exceeds the
U.S. Holders tax basis, the excess will be taxed as capital gain recognized on a sale or exchange of such ordinary shares. Because we do not expect to determine our earnings and profits in accordance with U.S. federal income tax principles,
U.S. Holders should expect that a distribution will generally be reported as a dividend for U.S. federal income tax purposes, even if that distribution would otherwise be treated as a tax-free return of capital or as capital gain under the rules
described above.

With respect to non-corporate U.S. Holders, certain dividends received from a qualified foreign corporation
may be subject to reduced rates of U.S. federal income taxation. A non-U.S. corporation is treated as a qualified foreign corporation with respect to dividends paid by that corporation on shares that are readily tradable on an established securities
market in the United States. We believe our ordinary shares, which are listed on the NYSE, are considered to be readily tradable on an established securities market in the United States, although there can be no assurance that this will continue to
be the case in the future. Non-corporate U.S. Holders that do not meet a minimum holding period requirement during which they are not protected from the risk of loss, or that elect to treat the dividend income as investment income
pursuant to Section 163(d)(4) of the Code, will not be eligible for the reduced rates of taxation regardless of our status as a qualified foreign corporation. In addition, even if the minimum holding period requirement has been met, the rate
reduction will not apply to dividends if the recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. You should consult your own tax advisors regarding the application of
these rules given your particular circumstances.

In the event that a U.S. Holder is subject to non-U.S. withholding taxes on
dividends paid to such U.S. Holder with respect to our ordinary shares, such U.S. Holder may be eligible, subject to certain conditions and limitations, to claim a foreign tax credit for such non-U.S. withholding taxes against the U.S. Holders
U.S. federal income tax liability or alternatively deduct such non-U.S. withholding taxes in computing such U.S.Holders U.S. federal income tax liability. Dividends paid to a U.S. Holder with respect to our ordinary shares are expected
to generally constitute foreign source income and to generally be treated as passive category income, for purposes of the foreign tax credit, except that a portion of such dividends may be treated as incomefrom U.S.
sources if (i) United States persons own, directly or indirectly, 50% or more of our ordinary shares (by vote or value) and (ii) we receive more than a de minimisamount of income from U.S. sources. The rules governing the foreign
tax credit and ability to deduct such non-U.S. withholding taxes are complex and involve the application of rules that depend upon your particular circumstances. You are urged to consult your own tax advisors regarding the availability of the
foreign tax credit or deduction under your particular circumstances.

Sale, Exchange or Other Disposition

For U.S. federal income tax purposes, a U.S. Holder generally will recognize taxable gain or loss on any sale, exchange or other taxable
disposition of our ordinary shares in an amount equal to the difference between the amount realized for our ordinary shares and the U.S. Holders tax basis in such ordinary shares. Such gain or loss will generally be capital gain or loss.
Capital gains of individuals derived with respect to capital assets held for more than one year generally are eligible for reduced rates of U.S. federal income taxation. The deductibility of capital losses is subject to limitations. Any gain or loss
recognized by a U.S. Holder will generally be treated as U.S. source gain or loss. You are urged to consult your tax advisors regarding the tax consequences if a non-U.S. tax is imposed on a sale, exchange or other disposition of our ordinary
shares, including the availability of the foreign tax credit or deduction under your particular circumstances.

Information Reporting and Backup Withholding

A U.S. Holder with interests in specified foreign financial assets (including, among other assets, our ordinary shares, unless such
shares were held on such U.S. Holders behalf through a financial institution) may be required to file an information report with the IRS if the aggregate value of all such assets exceeds certain threshold amounts. You should consult your own
tax advisor as to the possible obligation to file such information reports in light of your particular circumstances.

Moreover,
information reporting generally will apply to dividends in respect of our ordinary shares and the proceeds from the sale, exchange or other disposition of our ordinary shares that are paid to a U.S. Holder within the United States (and in certain
cases, outside the United States), unless the U.S. Holder is an exempt recipient. Backup withholding (currently at a rate of 28%) may also apply to such payments if the U.S. Holder fails to provide an appropriate certification with such U.S.
Holders taxpayer identification number or certification of exempt status. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a U.S.
Holders U.S. federal income tax liability provided the required information is timely furnished to the IRS. You should consult your tax advisors regarding the application of the U.S. information reporting and backup withholding rules to your
particular circumstances.

US Foreign Account Tax Compliance Act

Provisions under the Code and Treasury regulations thereunder, commonly referred to as FATCA, may impose 30% withholding on certain
payments made by a foreign financial institution (as defined in the Code) that has entered into an agreement with the Internal Revenue Service to perform certain diligence and reporting obligations with respect to the foreign financial
institutions accounts (each such foreign financial institution, a Participating Foreign Financial Institution). If we were treated as a foreign financial institution and if we become a Participating Foreign Financial Institution,
such withholding may be imposed on payments on our ordinary shares (to the extent such payments are considered foreign passthru payments) to any foreign financial institution (including an intermediary through which a holder may hold
ordinary shares) that is not a Participating Foreign Financial Institution or any other investor who does not provide information sufficient to establish that the investor is not subject to withholding under FATCA, unless such foreign financial
institution or investor is otherwise exempt from FATCA. The term foreign passthru payment is not yet defined and it is therefore not clear whether or to what extent payments on our ordinary shares would be considered foreign passthru
payments. Under recent IRS guidance, withholding on foreign passthru payments would not be required with respect to payments made before the later of January 1, 2019 or the date of publication in the Federal Register of final regulations
defining the term foreign passthru payment. You should consult your tax advisor regarding the potential impact of FATCA, or any intergovernmental agreement or non-US legislation implementing FATCA, on your investment in our ordinary
shares. FATCA IS PARTICULARLY COMPLEX AND ITS APPLICATION TO US, OUR ORDINARY SHARES AND HOLDERS OF OUR SHARES IS SUBJECT TO CHANGE. EACH HOLDER OF OUR SHARES SHOULD CONSULT ITS OWN TAX ADVISOR TO OBTAIN A MORE DETAILED EXPLANATION OF FATCA AND TO
LEARN HOW FATCA MIGHT AFFECT EACH HOLDER IN ITS PARTICULAR CIRCUMSTANCE.

Material Dutch Tax Consequences

General

The information set out
below is a summary of certain material Dutch tax consequences in connection with the acquisition, ownership and transfer of our ordinary shares. This summary does not purport to be a comprehensive description of all the Dutch tax considerations that
may be relevant to a particular holder of our ordinary shares. Such holders may be subject to special tax treatment under any applicable law and this summary is not intended to be applicable in respect of all categories of holders of our ordinary
shares.

This summary is based on the tax laws of the Netherlands as in effect on January 1, 2016, as well as regulations, rulings
and decisions of the Netherlands or of its taxing and other authorities available in printed

form on or before such date and now in effect, and as applied and interpreted by Netherlands courts, without prejudice to any amendments introduced at a later date and implemented with or without
retroactive effect. All of the foregoing is subject to change, which change could apply retroactively and could affect the continued validity of this summary.

For Dutch tax purposes, a holder of our ordinary shares may include an individual who, or an entity that, does not have the legal title to our
ordinary shares, but to whom nevertheless our ordinary shares are attributed based either on such individual or entity holding a beneficial interest in our ordinary shares or based on specific statutory provisions, including statutory provisions
pursuant to which our ordinary shares are attributed to an individual who is, or who has directly or indirectly inherited from a person who was, the settlor, grantor or similar originator of a trust, foundation or similar entity that holds our
ordinary shares, such as the separated private assets (afgezonderd particulier vermogen) provisions of the Dutch Income Tax Act 2001 (Wet inkomstenbelasting 2001) and the Dutch Gift and Inheritance Tax Act 1956 (Successiewet
1956).

Because it is a general summary, prospective holders of our ordinary shares should consult their own tax advisors as to the
Dutch or other tax consequences of the acquisition, holding and transfer of the ordinary shares including, in particular, the application to their particular situations of the tax considerations discussed below, as well as the application of foreign
or other tax laws.

This summary does not describe any tax consequences arising under the laws of any taxing jurisdiction other than the
Netherlands in connection with the acquisition, ownership and transfer of our ordinary shares. The Netherlands means the part of the Kingdom of the Netherlands located in Europe.

Any reference hereafter made to a treaty for the avoidance of double taxation concluded by the Netherlands, includes the Tax
Arrangement for the Kingdom of the Netherlands (Belastingregeling voor het Koninkrijk), the Tax Arrangement the Netherlands Curacao (Belastingregeling Nederland Curaco) and the Tax Arrangement for the country of the Netherlands
(Belastingregeling voor het land Nederland).

Dividend Withholding Tax

General

Dividends
paid on our ordinary shares to a holder of ordinary shares are generally subject to withholding tax of 15% imposed by the Netherlands. Generally, the dividend withholding tax will not be borne by us, but we will withhold from the gross dividends
paid on our ordinary shares. The term dividends for this purpose includes, but is not limited to:



| |  |  | distributions in cash or in kind, deemed and constructive distributions and repayments of paid-in capital not recognized for Dutch dividend withholding tax purposes;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | liquidation proceeds, proceeds of redemption of shares or, generally, consideration for the repurchase of shares in excess of the average paid-in capital recognized for Dutch dividend withholding tax purposes;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the nominal value of shares issued to a shareholder or an increase of the nominal value of shares, as the case may be, to the extent that it does not appear that a contribution to the capital recognized for Dutch
dividend withholding tax purposes was made or will be made; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | partial repayment of paid-in capital, recognized for Dutch dividend withholding tax purposes, if and to the extent that there are net profits (zuivere winst), within the meaning of the Dutch Dividend Withholding
Tax Act 1965 (Wet op de dividendbelasting 1965), unless the general meeting of shareholders has resolved in advance to make such a repayment and provided that the nominal value of the shares concerned has been reduced by a corresponding
amount by way of an amendment of our Amended and Restated Articles of Association.

Holder of Our Ordinary Shares Resident in the Netherlands

A holder of our ordinary shares who is, or who is deemed to be, a resident of the Netherlands can generally credit the withholding tax against
his Dutch income tax or Dutch corporate income tax liability and is generally entitled to a refund of dividend withholding taxes exceeding his aggregate Dutch income tax or Dutch corporate income tax liability, provided certain conditions are met,
unless such holder of our ordinary shares is not considered to be the beneficial owner of the dividends.

A holder of our ordinary shares
who is the recipient of dividends (the Recipient) will not be considered the beneficial owner of the dividends for this purpose if:



| |  |  | as a consequence of a combination of transactions, a person other than the Recipient wholly or partly benefits from the dividends;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | whereby such other person retains, directly or indirectly, an interest similar to that in the ordinary shares on which the dividends were paid; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | that other person is entitled to a credit, reduction or refund of dividend withholding tax that is less than that of the Recipient (Dividend Stripping).
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------

Holder of Our Ordinary Shares not Resident in the Netherlands

With respect to a holder of our ordinary shares, who is not and is not deemed to be a resident of the Netherlands for purposes of Dutch
taxation and who is considered to be a resident of a country other than the Netherlands under the provisions of a double taxation convention the Netherlands has concluded with such country, the following may apply. Such holder of our ordinary shares
may, depending on the terms of and subject to compliance with the procedures for claiming benefits under such double taxation convention, be eligible for a full or partial exemption from or a reduction or refund of Dutch dividend withholding tax.

In addition, an exemption from Dutch dividend withholding tax will generally apply to dividends distributed to certain qualifying
entities, provided that the following tests are satisfied:



| | (i) | the entity is a resident of another EU member state or of a designated state that is a party to the Agreement on the European Economic Area (currently Iceland, Norway and Liechtenstein), according to the tax laws of
such state;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | the entity at the time of the distribution has an interest in us to which the participation exemption as meant in article 13 of the Dutch Corporate Income Tax Act 1969 (Wet op de vennootschapsbelasting 1969) or
to which the participation credit as meant in article 13aa of the Dutch Corporate Income Tax Act 1969 would have been applicable, had such entity been a tax resident of the Netherlands;
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | the entity does not perform a similar function as an exempt investment institution (vrijgestelde beleggingsinstelling) or fiscal investment institution (fiscale beleggingsinstelling), as defined in
the Dutch Corporate Income Tax Act 1969; and
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | the entity is, in its state of residence, not considered to be resident outside the EU member states or the designated states that are party to the Agreement on the European Economic Area under the terms of a double
taxation convention concluded with a third state.
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The exemption from Dutch dividend withholding tax is not available if
pursuant to a provision for the prevention of fraud or abuse included in a double taxation treaty between the Netherlands and the country of residence of the non-resident holder of our ordinary shares, such holder would not be entitled to the
reduction of tax on dividends provided for by such treaty. Furthermore, the exemption from Dutch dividend withholding tax will only be available to the beneficial owner of the dividend.

##### Table of Contents

Furthermore, certain entities that are resident in another EU member state or in a designated
state that is a party to the Agreement on the European Economic Area (currently Iceland, Norway and Liechtenstein) and that are not subject to taxation levied by reference to profits in their state of residence, may be entitled to a refund of Dutch
dividend withholding tax, provided:



| | (i) | such entity, had it been a resident in the Netherlands, would not be subject to corporate income tax in the Netherlands;
| | --- | ------------------------------------------------------------------------------------------------------------------------



| | (ii) | such entity can be considered to be the beneficial owner of the dividends;
| | ---- | --------------------------------------------------------------------------



| | (iii) | such entity does not perform a similar function to that of a fiscal investment institution (fiscale beleggingsinstelling) or an exempt investment institution (vrijgestelde
beleggingsinstelling) as defined in the Dutch Corporate Income Tax Act 1969; and
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | certain administrative conditions are met.
| | ---- | ------------------------------------------

Dividend distributions to a U.S. holder of our
ordinary shares (with an interest of less than 10% of the voting rights in us) are subject to 15% dividend withholding tax, which is equal to the rate such U.S. holder may be entitled to under the Convention Between the Kingdom of the Netherlands
and the United States for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on Income, executed in Washington on December 18, 1992, as amended from time to time (the Netherlands-U.S.
Convention). As such, there is no need to claim a refund of the excess of the amount withheld over the tax treaty rate.

On the
basis of article 35 of the Netherlands-U.S. Convention, qualifying U.S. pension trusts are under certain conditions entitled to a full exemption from Dutch dividend withholding tax. Such qualifying exempt U.S. pension trusts must provide us form IB
96 USA, along with a valid certificate, for the application of relief at source from dividend withholding tax. If we receive the required documentation prior to the relevant dividend payment date, then we may apply such relief at source. If a
qualifying exempt U.S. pension trust fails to satisfy these requirements prior to the payment of a dividend, then such qualifying exempt pension trust may claim a refund of Dutch withholding tax by filing form IB 96 USA with the Dutch tax
authorities. On the basis of article 36 of the Netherlands-U.S. Convention, qualifying exempt U.S. organizations are under certain conditions entitled to a full exemption from Dutch dividend withholding tax. Such qualifying exempt U.S. organizations
are not entitled to claim relief at source, and instead must claim a refund of Dutch withholding tax by filing form IB 95 USA with the Dutch tax authorities.

The concept of Dividend Stripping, described above, may also be applied to determine whether a holder of our ordinary shares may be eligible
for a full or partial exemption from, reduction or refund of Dutch dividend withholding tax, as described in the preceding paragraphs.

In
general, we will be required to remit all amounts withheld as Dutch dividend withholding tax to the Dutch tax authorities. However, in connection with distributions received by us from our foreign subsidiaries, we are allowed, subject to certain
conditions, to reduce the amount of Dutch dividend withholding tax to be remitted to Dutch tax authorities by the lesser of:



| | (i) | 3% of the portion of the distribution paid by us that is subject to Dutch dividend withholding tax; and
| | --- | -------------------------------------------------------------------------------------------------------



| | (ii) | 3% of the dividends and profit distributions, before deduction of non-Dutch withholding taxes, received by us from qualifying foreign subsidiaries in the current calendar year (up to the date of the distribution by us)
and the two preceding calendar years, insofar as such dividends and profit distributions have not yet been taken into account for purposes of establishing the above-mentioned deductions.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For purposes of determining the 3% threshold under (i) above, a distribution by us is not taken into account in case the Dutch dividend
withholding tax withheld in respect thereof may be fully refunded, unless the recipient of such distribution is a qualifying entity that is not subject to corporate income tax.

Although this reduction reduces the amount of Dutch dividend withholding tax that we are required
to pay to the Dutch tax authorities, it does not reduce the amount of tax that we are required to withhold from dividends.

Tax on Income and
Capital Gains

General

The description of taxation set out in this section of this Annual Report is not intended for any holder of our ordinary shares, who:



| | (i) | is an individual and for whom the income or capital gains derived from the ordinary shares are attributable to employment activities the income from which is taxable in the Netherlands;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | is an entity that is a resident or deemed to be a resident of the Netherlands and that is, in whole or in part, not subject to or exempt from Netherlands corporate income tax;
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | is an entity that has an interest in us to which the participation exemption (deelnemingsvrijstelling) or the participation credit (deelnemingsverrekening) is applicable as set out in the Dutch
Corporate Income Tax Act 1969;
| | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | is a fiscal investment institution (fiscale beleggingsinstelling) or an exempt investment institution (vrijgestelde beleggingsinstelling) as defined in the Dutch Corporate Income Tax Act
1969; or
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | has a substantial interest (aanmerkelijk belang) or a deemed substantial interest as defined in the Dutch Income Tax Act 2001 in us.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------

Generally a holder of our ordinary shares will have a substantial interest in us in the meaning of paragraph (v) above if he holds, alone
or together with his partner (statutorily defined term), whether directly or indirectly, the ownership of, or certain other rights over shares representing 5% or more of our total issued and outstanding capital (or the issued and outstanding capital
of any class of our shares), or rights to acquire shares, whether or not already issued, which represent at any time 5% or more of our total issued and outstanding capital (or the issued and outstanding capital of any class of our shares) or the
ownership of certain profit participating certificates that relate to 5% or more of the annual profit and/or to 5% or more of the liquidation proceeds of us. A holder of our ordinary shares will also have a substantial interest in us if one of
certain relatives of that holder or of his partner (a statutory defined term) has a substantial interest in us.

If a holder of our
ordinary shares does not have a substantial interest, a deemed substantial interest will be present if (part of) a substantial interest has been disposed of, or is deemed to have been disposed of, without recognizing taxable gain.

Residents of the Netherlands

Individuals

An individual
who is resident or deemed to be resident in the Netherlands (a Dutch Resident Individual) and who holds our ordinary shares will be subject to Netherlands income tax on income and/or capital gains derived from our ordinary shares at the
progressive rate (up to 52%; rate for 2014) if:



| | (i) | the holder derives profits from an enterprise or deemed enterprise, whether as an entrepreneur (ondernemer) or pursuant to a co-entitlement to the net worth of such enterprise (other than as an entrepreneur or a
shareholder), to which enterprise the ordinary shares are attributable; or
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | the holder derives income or capital gains from the ordinary shares that are taxable as benefits from miscellaneous activities (resultaat uit overige werkzaamheden, as defined in the Dutch Income Tax
Act 2001), which include the performance of activities with respect to the ordinary shares that exceed regular, active portfolio management (normaal, actief vermogensbeheer) and also includes benefits resulting from a lucrative interest
(lucratief belang).

##### Table of Contents

If conditions (i) and (ii) above do not apply, any holder of our ordinary shares
who is a Dutch Resident Individual will be subject to Netherlands income tax on a deemed return regardless of the actual income and/or capital gains derived from our ordinary shares. This deemed return has been fixed at a rate of 4% of the
individuals yield basis (rendementsgrondslag) insofar as this exceeds a certain threshold (heffingsvrijvermogen). The individuals yield basis is determined as the fair market value of certain qualifying assets (including,
as the case may be, the ordinary shares) held by the Dutch Resident Individual less the fair market value of certain qualifying liabilities, both determined on January 1 of the relevant year. The deemed return of 4% will be taxed at a rate of
30% (rate for 2016).

Entities

An entity that is resident or deemed to be resident in the Netherlands (a Dutch Resident Entity) will generally be subject to
Netherlands corporate income tax with respect to income and capital gains derived from the ordinary shares. The Netherlands corporate income tax rate is 20% for the first 200,000 of the taxable amount, and 25% for the excess of the taxable
amount over 200,000 (rates applicable for 2016).

Non-Residents of the Netherlands

A person who is neither a Dutch Resident Individual nor Dutch Resident Entity (a Non-Dutch Resident) and who holds our ordinary
shares is generally not subject to Netherlands income tax or corporate income tax (other than dividend withholding tax described above) on income and capital gains derived from the ordinary shares, provided that:



| | (i) | such Non-Dutch Resident does not derive profits from an enterprise or deemed enterprise, whether as an entrepreneur (ondernemer) or pursuant to a co-entitlement to the net worth of such enterprise (other than as
an entrepreneur or a shareholder) which enterprise is, in whole or in part, carried on through a permanent establishment or a permanent representative in the Netherlands and to which enterprise or part of an enterprise, as the case may be, the

| | (ii) | in the case of a Non-Dutch Resident who is an individual, such individual does not derive income or capital gains from the Shares that are taxable as benefits from miscellaneous activities (resultaat
uit overige werkzaamheden, as defined in the Dutch Income Tax Act 2001) performed or deemed to be performed in the Netherlands, which include the performance of activities with respect to the ordinary shares that exceed regular,
active portfolio management (normaal, actief vermogensbeheer) and also includes benefits resulting from a lucrative interest (luctratief belang); and
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | such Non-Dutch Resident is neither entitled to a share in the profits of an enterprise nor co-entitled to the net worth of such enterprise effectively managed in the Netherlands, other than by way of the holding of
securities or, in the case of an individual, through an employment contract, to which enterprise the ordinary shares or payments in respect of the ordinary shares are attributable.
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

A Non-Dutch Resident that nevertheless falls under any of the paragraphs (i) through (iii) mentioned above, may be subject to
Netherlands income tax or corporate income tax on income and capital gains derived from our ordinary shares. In case such holder of our ordinary shares is considered to be a resident of a country other than the Netherlands under the provisions of a
double taxation convention the Netherlands has concluded with such country, the following may apply. Such holder of ordinary shares may, depending on the terms of and subject to compliance with the procedures for claiming benefits under such double
taxation convention, be eligible for a full or partial exemption from Netherlands taxes (if any) on (deemed) income or capital gains in respect of the ordinary shares, provided such holder is entitled to the benefits of such double taxation
convention.

Gift or Inheritance Tax

No Netherlands gift or inheritance taxes will be levied on the transfer of our ordinary shares by way of gift by or on the death of a holder of
our ordinary shares, who is neither a resident nor deemed to be a resident of the Netherlands for the purpose of the relevant provisions, unless:



| | (i) | the transfer is construed as an inheritance or bequest or as a gift made by or on behalf of a person who, at the time of the gift or death, is or is deemed to be a resident of the Netherlands for the purpose of the
relevant provisions;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | such holder dies while being a resident or deemed resident of the Netherlands within 180 days after the date of a gift of the ordinary shares; or
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | the gift is made under a condition precedent and such holder is deemed to be resident of the Netherlands at the time the condition is fulfilled.
| | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------

For purposes of the Dutch Gift and Inheritance Tax Act 1956, an individual who is of Dutch nationality will be deemed to be a resident of the
Netherlands if he has been a resident in the Netherlands at any time during the ten years preceding the date of the gift or his death.

For purposes of Netherlands gift tax, an individual will, irrespective of his nationality, be deemed to be resident of the Netherlands if he
has been a resident in the Netherlands at any time during the 12-months preceding the date of the gift.

Applicable tax treaties may
override such deemed residency.

Value Added Tax

No Netherlands value added tax will be payable by a holder of our ordinary shares in consideration for the offer of our ordinary shares (other
than value added taxes on fees payable in respect of services not exempt from Netherlands value added tax).

Other Taxes or Duties

No Netherlands registration tax, custom duty, stamp duty or any other similar tax or duty, other than court fees, will be payable in
the Netherlands by a holder of our ordinary shares in respect of or in connection with the acquisition, ownership and disposition of the ordinary shares.

|B. | Managements Annual Report on Internal Control over Financial Reporting and Attestation Report of the Registered Public Accounting Firm
|-- | ---------------------------------------------------------------------------------------------------------------------------------------

The management of the Company, including the Chief Executive Officer and Chief Financial Officer, is responsible for establishing and
maintaining adequate internal controls over financial reporting, as defined in the Securities Exchange Act of 1934, as amended, Rule 13a-15(f).

The Companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability
of financial reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) and as endorsed by the
European Union (EU).

The Companys internal control over financial reporting includes those policies and procedures that
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with IFRS, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and
(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of the effectiveness of internal control to future periods are subject to the risk that controls may become inadequate because of changes in conditions, and that the degree of compliance with the policies or procedures may
deteriorate.

Constelliums management has assessed the effectiveness of the Companys internal controls over financial
reporting as of December 31, 2015 based on the criteria established in Internal Control  Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and, based on such criteria,
Constelliums management has concluded that, as of December 31, 2015, the Company ́s internal control over financial reporting is effective.



|C. | Attestation report of the registered public accounting firm.
|-- | ------------------------------------------------------------

The effectiveness of the
Companys internal control over financial reporting as of December 31, 2015 has been audited by PricewaterhouseCoopers Audit, an independent registered public accounting firm, as stated in their report which appears herein.



|D. | Changes in Internal Control over Financial Reporting
|-- | ----------------------------------------------------

During the period covered by this
report, we have not made any change to our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 16A. Audit Committee Financial Expert

Our board of directors has determined that Messrs. Brandjes, Guillemot, Hartman, Maugis, Ormerod and Paschke and Ms. Walker satisfy the
independence requirements set forth in Rule 10A-3 under the Exchange Act. Our board of directors has also determined that each of Messrs. Paschke and Ormerod and Ms. Walker is an audit committee financial expert as
defined in Item 16A of Form 20-F under the Exchange Act.

Item 16G. Corporate Governance

Dutch Corporate Governance Code

Since we
are a public company and list our Class A Ordinary shares on the New York Stock Exchange (NYSE) and on the Euronext Paris, regulated markets, we are subject to comply with the Dutch Corporate Governance Code (the Dutch
Code). The Dutch Code, as amended, became effective on January 1, 2009, and applies to all Dutch companies listed on a government-recognized stock exchange, whether in the Netherlands or elsewhere.

The Dutch Code is based on a comply or explain principle. Accordingly, companies are required to disclose in their annual report
filed in the Netherlands whether or not they are complying with the various rules of the Dutch Code that are addressed to the board of directors or, if any, the supervisory board of the company and, if they do not apply those provisions, to give the
reasons for such non-application. The Dutch Code contains principles and best practice provisions for managing boards, supervisory boards, shareholders and general meetings of shareholders, financial reporting, auditors, disclosure, compliance and
enforcement standards.

We acknowledge the importance of good corporate governance. The board of directors agrees with the general
approach and with the majority of the provisions of the Dutch Code. However, considering our interests and the interests of our stakeholders, at this stage, we do not apply a limited number of best practice provisions either because such provisions
conflict with or are inconsistent with the corporate governance rules of the NYSE and U.S. securities laws that apply to us, or because such provisions do not reflect best practices of global companies listed on the NYSE.

The best practice provisions we do not apply include the following:



| |  |  | An executive board member may not be a member of the supervisory board (or be a non-executive board member) of more than two Dutch listed companies. Nor may an executive board member be the chairman of the
supervisory board (or a board) of a listed company. Membership of the supervisory board (or non-executive board positions) of other companies within the group to which the Company belongs does not count for this purpose. The acceptance by an
executive board member of membership of the supervisory board or acceptance of a position as non-executive member of the board of a listed company requires the approval of the non-executive board members. Other important positions held by an
executive board member shall be notified to the board (best practice provision II.1.8).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our board of directors intends
to evaluate a policy with respect to the number of additional board memberships that a board member may have. We will comply with applicable NYSE and SEC rules and the relevant provisions of Dutch law.

##### Table of Contents

| |  |  | Remuneration (Principles II.2, III.7 and associated best practice provisions).
| | - |  | ------------------------------------------------------------------------------

We
believe that our remuneration policy helps to focus directors, officers and other employees and consultants on business performance that creates shareholder value, to encourage innovative approaches to the business of the Company and to encourage
ownership of our shares by directors, officers and other employees and consultants. Aspects of our remuneration policy may deviate from the Dutch Code to comply with applicable NYSE and SEC rules.



| |  |  | Conflicts of interest and related party transactions (Principles II.3, III.6 and associated best practice provisions).
| | - |  | ----------------------------------------------------------------------------------------------------------------------

We have a policy on conflicts of interests and related party transactions. The policy provides that the determination of whether a conflict of
interest exists will be made in accordance with Dutch law and on a case-by-case basis. We believe that it is not in the interest of the Company to provide for deemed conflicts of interests.



| |  |  | Independence (Principle III.2 and associated best practice provisions).
| | - |  | -----------------------------------------------------------------------

We may need to
deviate from the Dutch Codes independence definition for board members either because such provisions conflict with or are inconsistent with the corporate governance rules of the NYSE and U.S. securities laws that apply to us, or because such
provisions do not reflect best practices of global companies listed on the NYSE.



| |  |  | The chairman of the board may not also be or have been an executive board member (best practice provisions III.4.2 and III.8.1).
| | - |  | --------------------------------------------------------------------------------------------------------------------------------

Mr. Evans has served as our Chairman since December 2012. Mr. Evans also served as our interim chief executive officer from December
2011 until the appointment of Mr. Pierre Vareille in March 2012. We believe the deviation from the Dutch Code is justified considering the short interim period during which Mr. Evans acted as executive board member.



| |  |  | The vice-chairman of the board shall deputize for the chairman when the occasion arises. By way of addition to best practice provision III.1.7, the vice-chairman shall act as contact for individual board members
concerning the functioning of the chairman of the board (best practice provision III.4.4).
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We intend to comply with
certain corporate governance requirements of the NYSE in lieu of the Dutch Code. Under the corporate governance requirements of the NYSE, we are not required to appoint a vice-chairman. If the chairman of our board of directors is absent, the
directors that are present will elect a non-executive board member to chair the meeting.



| |  |  | The terms of reference of the board shall contain rules on dealing with conflicts of interest and potential conflicts of interest between board members and the external auditor on the one hand and the company on the
other. The terms of reference shall also stipulate which transactions require the approval of the non-executive board members. The company shall draw up regulations governing ownership of and transactions in securities by board members, other than
securities issued by their own company (best practice provision III.6.5).
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Company believes that board
members should not be further limited by internal regulations in addition to the rules and restrictions under applicable securities laws.



| |  |  | The majority of the members of the board of directors shall be non-executive directors and are independent within the meaning of best practice provision III.2.2 (best practice provision III.8.4).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Six non-executive members of our board are independent. It is our view that given the nature of our business and the
practice in our industry and considering our shareholder structure, it is justified that only six non-executive directors are independent. We may need to deviate from the Dutch Codes independence definition for board members either because
such provisions conflict with or are inconsistent with the corporate governance rules of the NYSE and U.S. securities laws that apply to us, or because such provisions do not reflect best practices of global companies listed on the NYSE. As an



-133-

##### Table of Contents

example, under NYSE rules, 8 of our current 9 directors are independent. We may need to further deviate from the Dutch Codes independence definition for board members when looking for the
most suitable candidates. For example, a current board member or future board candidate may have particular knowledge of, or experience in, the downstream aluminium rolled and extruded products and related businesses, but may not meet the definition
of independence in the Dutch Code. As such background is very important to the efficacy of our board of directors in managing a highly technical business, and because our industry has relatively few participants, our board may decide to nominate
candidates for appointment who do not fully comply with the criteria as listed under best practice provision III.2.2 of the Dutch Code.



| |  |  | The company shall formulate an outline policy on bilateral contacts, as described in the Dutch Code, with the shareholders and publish this policy on its website (best practice provision IV.3.13).
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We will not formulate an outline policy on bilateral contacts with the shareholders. We will comply with
applicable NYSE and SEC rules and the relevant provisions of applicable law with respect to contacts with our shareholders. We believe that all contacts with our shareholders should be assessed on a case-by-case basis.



| |  |  | A person may be appointed as non-executive member of the board for a maximum of three 4-year terms (best practice provisions III.3.5).
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

On June 11, 2015 Mr. Brandjes, Mr. Guillemot, Mr. Hartman, Mr. Ormerod and Ms. Walker were each re-appointed as
Non-Executive Directors for a period of one year.

Mr. Maugis, Mr. Nord and Mr. Paschke were each re-appointed as
Non-Executive Directors for a period of two years.

This deviation gives the shareholders the possibility to already vote on a possible
reappointment after one or two years instead of four years. Since we are a relatively recent public company of only 3 years, the maximum term is not an issue at this point.



| |  |  | Pursuant to best practice provision III.3.6. the non-executive board members shall draw up a retirement schedule in order to avoid, as far as possible, a situation in which many non-executive board members retire at
the same time. The retirement schedule shall be made generally available and shall be posted on the companys website.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As we are a relatively recent public company and (most) of our non-executive board members are (re)appointed for one year, we currently do not
have a retirement schedule.



| |  |  | Pursuant to best practice provision IV.1.1, a general meeting of shareholders is empowered to cancel binding nominations of candidates for the board, and to dismiss members of the board by a simple majority of votes
of those in attendance, although the company may require a quorum of at least one-third of the voting rights outstanding. If such quorum is not represented, but a majority of those in attendance vote in favor of the proposal, a second meeting may be
convened in the future and its vote will be binding, even without a one-third quorum.Our Amended and Restated Articles of Association currently provide that a general meeting of shareholders may at all times overrule a binding nomination by a
resolution adopted by at least a two-thirds majority of the votes cast, if such majority represents more than half of the issued share capital. Although this constitutes a deviation from provision IV.1.1 of the Dutch Code, we hold the view that
these provisions will enhance the continuity of our management and policies.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Best practice provision IV.3.1 recommends that we should enable the shareholders to follow in real time all meetings with analysts, investors and press conferences. We believe that enabling shareholders to follow in
real time all the meetings with analysts, presentations to analysts, presentations to investors as referred to in best practice provision IV.3.1 of the Dutch Code would create an excessive burden on our resources. We will ensure that analyst
presentations are posted on our website after meetings with analysts. In addition, we hold quarterly earnings calls where we report our financial results to which all our investors are invited to attend via web conference.

##### Table of Contents

The NYSE requires that we disclose to investors any significant ways in which our corporate
governance practices differ from those followed by U.S. domestic companies under NYSE requirements.

Among these differences, shareholder
approval is required by the NYSE prior to the issuance of ordinary stock:



| |  |  | to a director, officer or substantial security holder of the company (or their affiliates or entities in which they have a substantial interest) in excess of one percent of either the number of shares of ordinary stock
or the voting power outstanding before the issuance, with certain exceptions;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | that will have voting power equal to or in excess of 20 percent of either the voting power or the number of shares outstanding before the issuance, with certain exceptions; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | that will result in a change of control of the issuer.
| | - |  | ------------------------------------------------------

Under Dutch rules, shareholders can
delegate this approval to the Board of Directors at the annual shareholders meeting. In the past, our shareholders have delegated this approval power to our Board at our annual meeting.

In some situations, NYSE rules are more stringent, and in others the Dutch rules are. Other significant differences include:



| |  |  | NYSE rules require shareholder approval for changes to equity compensation plans, but under Dutch rules, shareholder approval is only required for changes to equity compensation plans for members of the Board of
Directors;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Under Dutch corporate governance rules the audit and remuneration committees may not be chaired by the Chairman of the Board;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | Under Dutch rules, auditors must be appointed by the general meeting of shareholders. NYSE rules require only that they be appointed by the audit committee;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Both NYSE and Dutch rules require that a majority of the Board of Directors be independent, but the definition of independence under each set of rules is not identical. For example, Dutch rules require a longer
look-back period for former directors; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Dutch rules permit deviation from the rules if the deviations are explained in accordance with the rules. The NYSE rules do not allow such deviations.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Constellium N.V.:

In our opinion,
the accompanying consolidated statement of financial position and the related consolidated statements of income, comprehensive income / (loss), changes in equity and cash flows present fairly, in all material respects, the financial position of
Constellium N.V. (the Company) and its subsidiaries at December 31, 2015 and December 31, 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015 in conformity with
International Financial Reporting Standards as issued by the International Accounting Standards Board and in conformity with International Financial Reporting Standards as adopted by the European Union. Also in our opinion, the Company maintained,
in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control Integrated Framework (2013) issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO). The Companys management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal
control over financial reporting included in the accompanying Managements Annual Report on Internal Control over Financial Reporting.

Our responsibility is
to express opinions on these financial statements and on the Companys internal control over financial reporting based on our audits (which were integrated audits in 2015 and 2014). We conducted our audits in accordance with the standards of
the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective
internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over
financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as
we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A companys internal control over
financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.
A companys internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures
of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of
the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

Note 2Summary of Significant Accounting Policies

2.1.
Statement of compliance

The consolidated financial statements of Constellium N.V. and its subsidiaries have been prepared in accordance with
International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) and as endorsed by the European Union (EU). The Groups application of IFRS results in no difference between IFRS as issued by
the IASB and IFRS as endorsed by the EU (http://ec.europa.eu/internal_market/accounting/ias/index_en.htm).

The consolidated financial statements
have been authorized for issue by the Board of Directors at its meeting held on March 13, 2016.

2.2. Application of new and revised International Financial
Reporting Standards (IFRS) and interpretations

Standards and Interpretations with an application date for the Group at January 1, 2015:



| |  |  | Amendments to IAS 19, Defined Benefit Plans: Employee Contributions. This amendment clarifies the requirements related to contributions from employees or third parties. The Group applied this amendment in
2013 and there is no impact on the Group financial statements.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Annual Improvements to IFRSs 2010-2012 Cycle and to IFRSs 2011-2013 Cycle. These Annual Improvements have no impact on the Group financial statements.

2.3. New standards and interpretations not yet mandatorily applicable

The Group has not applied the following new, revised and amended standards and interpretations that have been issued but are not yet effective and which
could affect the Groups future consolidated financial statements:

IFRS 9, Financial instruments, addresses the classification,
measurement and recognition of financial assets and financial liabilities. It will replace the guidance in IAS 39, Financial instruments that relates to the classification and measurement of financial instruments.

Modifications introduced by IFRS 9 relate primarily to:



| |  |  | classification and measurement of financial assets. The basis of classification depends on the entitys business model and the contractual cash flow characteristics of the financial asset.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | depreciation of receivables, now based on the expected credit losses model.
| | - |  | ---------------------------------------------------------------------------



| |  |  | hedge accounting.
| | - |  | -----------------

The standard will be effective for accounting periods beginning on or after
January 1, 2018.

IFRS 15, Revenue from contracts with customers deals with revenue recognition and establishes principles for
reporting information to users of financial statements about the nature, amount, timing and uncertainty of revenue and cash flows arising from an entitys contracts with customers. Revenue is recognized when a customer obtains control of a good
or service and thus has the ability to direct the use and obtain the benefits from the good or service. The standard replaces IAS 18, Revenue and IAS 11, Construction contracts and related interpretations. The standard will
be effective for accounting periods beginning on or after January 1, 2018.

IFRS 16, Leases deals with principles for the
recognition, measurement, presentation and disclosures of leases. The standard provides an accounting model, requiring lessee to recognize assets and liabilities for all leases unless the lease term is 12 months or less or the underlying asset has a
low value. The lessor accounting approach remains unchanged. The standard will replace IAS 17, Lease and will be effective for accounting periods beginning on or after January 1, 2019.

The impact of these standards on the Groups results and financial situation will be evaluated in 2016.

2.4. Basis of preparation

In accordance with IAS 1,
Presentation of Financial Statements, the Consolidated Financial Statements are prepared on the assumption that Constellium is a going concern and will continue in operation for the foreseeable future.

The financial position of the Group, its cash flows, liquidity position and borrowing facilities are described in the financial statements respectively
in NOTE 17Cash and Cash Equivalents, NOTE 19Borrowings and NOTE 23Financial Risk Management.

The Groups forecast and
projections, taking account of reasonably possible changes in trading performance, including an assessment of the current macroeconomic environment, indicate that the Group should be able to operate within the level of its current facilities and
related covenants.

Accordingly the Group continues to adopt the going concern basis in preparing the Consolidated Financial Statements. Management
considers that this assumption is not invalidated by Constelliums

negative equity as at December 31, 2015. This assessment was confirmed by the Board of Directors at its meeting held on March 13, 2016.

2.5 Presentation of the operating performance of each operating segment and of the Group

In accordance with IFRS 8, Operating Segments, operating segments are based upon product lines, markets and industries served, and are
reported in a manner consistent with the internal reporting provided to the chief operating decision-maker (CODM). The CODM, who is responsible for allocating resources and assessing performance of the operating segments, has been
identified as the Chief Executive Officer.

Constelliums CODM measures the profitability and financial performance of its operating segments
based on Adjusted EBITDA as it illustrates the underlying performance of continuing operations by excluding non-recurring and non-operating items. Adjusted EBITDA is defined as income from continuing operations before income taxes, results from
joint ventures, net finance costs, other expenses and depreciation and amortization as adjusted to exclude restructuring costs, impairment charges, unrealized gains or losses on derivatives and on foreign exchange differences, metal price lag, Share
Equity Plan expense, effects of purchase accounting adjustments, start-up costs or acquisition, integration and separation costs, certain incremental costs and other exceptional, unusual or generally non-recurring items.

2.6. Principles governing the preparation of the Consolidated Financial Statements

Basis of consolidation

These consolidated financial
statements include all the assets, liabilities, equity, revenues, expenses and cash flows of the entities and businesses controlled by Constellium. All intercompany transactions and balances between Group companies are eliminated.

Subsidiaries are entities over which the Group has control. The Group controls an entity when the Group has power over the investee, is exposed to, or
has rights to variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity.

Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control
ceases.

Investments over which the Group has significant influence or joint control are accounted under the equity method. The investments are
initially recorded at cost. Subsequently they are increased or decreased by the Groups share in the profit or loss, or by other movements reflected directly in the equity of the entity.

Business combination

The Group applies the acquisition
method to account for business combinations.

The consideration transferred for the acquisition of a subsidiary is the fair value of the assets
transferred, the liabilities assumed and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Identifiable assets acquired
and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. The amount of non-controlling interest is determined for each business combination and is either based
on the fair value (full goodwill method) or the present ownership instruments proportionate share in the

##### Table of Contents

recognized amounts of the acquirees identifiable net assets, resulting in recognition of only the share of goodwill attributable to equity holders of the parent (partial goodwill method).

Goodwill is initially measured as the excess of the aggregate of the consideration transferred and the amount of non-controlling interest over the
net identifiable assets acquired and liabilities assumed. If this consideration is lower than the fair value of the net assets of the subsidiary acquired, the difference is recognized as a gain in Other gains / (losses)net in the Consolidated
Income Statement.

At the acquisition date, the Group recognizes the identifiable acquired assets, liabilities and contingent liabilities
(identifiable net assets) of the subsidiaries on the basis of fair value at the acquisition date. Recognized assets and liabilities may be adjusted during a maximum of 12 months from the acquisition date, depending on new information obtained about
the facts and circumstances existing at the acquisition date.

Significant assumptions used in determining allocation of fair value include the
following valuation approaches: the cost approach, the income approach and the market approach which are determined based on cash flow projections and related discount rates, industry indices, market prices regarding replacement cost and comparable
market transactions.

Acquisition related costs are expensed as incurred and included in Other gains / (losses)net in the Consolidated Income
Statement.

Cash-generating units

The reporting units
(which generally correspond to an industrial site), the lowest level of the Groups internal reporting, have been identified as its cash-generating units.

Goodwill

Goodwill arising on a business combination is
carried at cost as established at the date of the business combination less accumulated impairment losses, if any.

Goodwill is allocated and
monitored at the operating segments level which are the groups of cash-generating units that are expected to benefit from the synergies of the combination. The operating segments represent the lowest level within the Group at which the goodwill is
monitored for internal management purposes.

On disposal of the relevant cash-generating units, the attributable amount of goodwill is included in
the determination of the gain or loss on disposal.

Impairment of goodwill

A group of cash-generating units to which goodwill is allocated is tested for impairment annually, or more frequently when there is an indication that
the group of units may be impaired.

The net carrying value of a group of cash-generating units is compared to its recoverable amount, which is the
higher of the value in use and the fair value less cost of disposal.

Value in use calculations use cash flow projections based on financial budgets
approved by management and covering usually a 5-year period. Cash flows beyond this period are estimated using a perpetual long-term growth rate for the subsequent years.



F-11



---

##### Table of Contents

The value in use is the sum of discounted cash flows over the projected period and the terminal value.
Discount rates are determined based on the weighted-average cost of capital of each operating segment.

The fair value is the price that would be
received for the group of cash-generating units, in an orderly transaction, from a market participant. This value is estimated on the basis of available and relevant market data or a discounted cash flow model incorporating a market
participants assumptions.

An impairment loss for goodwill is recognized for the amount by which the group of units carrying amount exceeds
its recoverable amount.

Any impairment loss for goodwill is allocated first to reduce the carrying amount of any goodwill allocated to the group of
cash-generating units and then, to the other assets of the group of units pro rata on the basis of the carrying amount of each asset in the group of units.

Any impairment loss is recognized in the line Impairment in the Consolidated Income Statement. An impairment loss recognized for goodwill cannot be
reversed in subsequent periods.

Non-current assets (and disposal groups) classified as held for sale & Discontinued operations

IFRS 5, Non-current Assets Held for Sale and Discontinued Operations defines a discontinued operation as a component of an entity that
(i) generates cash flows that are largely independent from cash flows generated by other components, (ii) is held for sale or has been sold, and (iii) represents a separate major line of business or geographic areas of operations.

Assets and liabilities are classified as held for sale when their carrying amount will be recovered principally through a sale transaction rather
than through continuing use. This condition is regarded as met only when the sale is highly probable and the non-current asset (or disposal group) is available for immediate sale in its present condition.

Assets and liabilities are stated at the lower of carrying amount and fair value less costs to sell if their carrying amount is to be recovered
principally through a sale transaction rather than through continuing use.

Assets and liabilities held for sale are reflected in separate line
items in the Consolidated Statement of Financial Position of the period during which the decision to sell is made.

The results of discontinued
operations are shown separately in the Consolidated Income Statement and Consolidated Statement of Cash Flows.

Foreign currency transactions and foreign
operations

Functional currency

Items included in the consolidated financial statements of each of the entities and businesses of Constellium are measured using the currency of the
primary economic environment in which each of them operates (their functional currency).

Foreign currency transactions:

Transactions denominated in currencies other than the functional currency are converted to the functional currency at the exchange rate in effect at the
date of the transaction. Foreign exchange

gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are
recognized in the Consolidated Income Statement, except when deferred in other comprehensive income as qualifying cash flow hedges and qualifying net investment hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented within Finance costsnet.

Foreign exchange gains and losses that relate to commercial transactions are presented in Cost of sales. All other foreign exchange gains and losses,
including those that relate to foreign currency derivatives hedging commercial transactions, are presented within Other gains/ (losses)net.

Foreign operations: presentation currency and foreign currency translation

In the preparation of the consolidated financial statements, the year-end balances of assets, liabilities and components of equity of Constelliums
entities and businesses are translated from their functional currencies into Euros, the presentation currency of the Group, at their respective year-end exchange rates; and the revenues, expenses and cash flows of Constelliums entities and
businesses are translated from their functional currencies into Euros using average exchange rates for the period.

The net differences arising from
exchange rate translation are recognized in the Consolidated Statement of Comprehensive Income / (Loss).

The following table summarizes the main
exchange rates used for the preparation of the Consolidated Financial Statements of the Group:

Revenue recognition

Revenue
is measured at the fair value of the consideration received or receivable.

Revenue from product sales, net of trade discounts, allowances and
volume-based incentives, is recognized once delivery has occurred, provided that persuasive evidence exists that all of the following criteria are met:



| |  |  | The significant risks and rewards of ownership of the product have been transferred to the buyer;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | Neither continuing managerial involvement to the degree usually associated with ownership, nor effective control over the goods sold, has been retained by Constellium;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The amount of revenue can be measured reliably;
| | - |  | -----------------------------------------------



| |  |  | It is probable that the economic benefits associated with the sale will flow to Constellium; and
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | The costs incurred or to be incurred in respect of the sale can be measured reliably.
| | - |  | -------------------------------------------------------------------------------------



F-13

##### Table of Contents

The Group also enters into tolling agreements whereby clients loan the metal which the Group will then
manufacture for them. In these circumstances, revenue is recognized when services are provided at the date of redelivery of the manufactured metal.

Amounts billed to customers in respect of shipping and handling are classified as revenue where the Group is responsible for carriage, insurance and
freight. All shipping and handling costs incurred by the Group are recognized in Cost of sales.

Deferred tooling revenue and related costs

Certain automotive long term contracts include the design and manufacture of customized parts. To manufacture such parts, certain specialized or
customized tooling is required. The Group accounts for the tooling revenue and related costs provided by third party manufacturers in accordance with the provisions of IAS 11, Construction Contracts, i.e. revenue and expenses are
recognized on the basis of percentage of completion of the contract.

Research and development costs

Costs incurred on development projects are recognized as intangible assets when the following criteria are met:



| |  |  | it is technically feasible to complete the intangible asset so that it will be available for use;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | Management intends to complete and use the intangible asset;
| | - |  | ------------------------------------------------------------



| |  |  | There is an ability to use the intangible asset;
| | - |  | ------------------------------------------------



| |  |  | It can be demonstrated how the intangible asset will generate probable future economic benefits;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | Adequate technical, financial and other resources to complete the development and use or sell the intangible asset are available; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The expenditure attributable to the intangible asset during its development can be reliably measured.
| | - |  | -----------------------------------------------------------------------------------------------------

Where development expenditures do not meet these criteria, they are expensed as incurred. Development costs previously recognized as expenses are not
recognized as an asset in a subsequent period.

Other gains / (losses)net

Other gains / (losses)net include realized and unrealized gains and losses on derivatives accounted for at fair value through profit or loss and
unrealized exchange gains and losses from the remeasurement of monetary assets and liabilities.

Other gains / (losses)net separately
identifies other unusual, infrequent or non-recurring items. Such items are those that in managements judgment need to be disclosed by virtue of their size, nature or incidence. In determining whether an event or transaction is specific,
management considers quantitative as well as qualitative factors such as the frequency or predictability of occurrence.

Interest income and expense

Interest income is recorded using the effective interest rate method on loans receivables and on the interest bearing components of cash and cash
equivalents.



F-14



---

##### Table of Contents

Interest expense on short and long-term financing is recorded at the relevant rates on the various
borrowing agreements.

Borrowing costs (including interests) incurred for the construction of any qualifying asset are capitalized during the period
of time required to complete and prepare the asset for its intended use.

Share-based payment arrangements

Equity-settled share-based payments to employees and others providing similar services are measured at the fair value of the equity instruments at the
grant date.

The fair value determined at the grant date of the equity-settled share-based payments is expensed on a straight-line basis over the
vesting period, based on Groups estimate of equity instruments that will eventually vest, with a corresponding increase in equity. At the end of each reporting year, the Group revises its estimate of the number of equity instruments expected
to vest.

Property, plant and equipment

Recognition and measurement

Property,
plant and equipment acquired by the Company are recorded at cost, which comprises the purchase price (including import duties and non-refundable purchase taxes), any costs directly attributable to bringing the asset to the location and condition
necessary for it to be capable of operating in the manner intended by management and the estimated close down and restoration costs associated with the asset. Borrowing costs (including interests) directly attributable to the acquisition or
construction of a Property, plant and equipment are included in the cost. Subsequent to the initial recognition, Property, plant and equipment are measured at cost less accumulated depreciation and impairment, if any. Costs are capitalized into
construction work in progress until such projects are completed and the assets are available for use.

Subsequent costs

Enhancements and replacements are capitalized as additions to Property, plant and equipment only when it is probable that future economic benefits
associated with them will flow to the Company and the cost of the item can be measured with reliability. Ongoing regular maintenance costs related to Property, plant and equipment are expensed as incurred.

Depreciation

Land is not depreciated.
Property, plant and equipment are depreciated over the estimated useful lives of the related assets using the straight-line method as follows:



| |  |  | Buildings 1050 years;
| | - |  | ----------------------



| |  |  | Machinery and equipment 340 years; and
| | - |  | ---------------------------------------



| |  |  | Vehicles 58 years.
| | - |  | -------------------

Intangible assets

Recognition and measurement

Technology
and Customer relationships acquired in a business combination are recognized at fair value at the acquisition date. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and impairment losses. The
useful lives of the Group intangible assets are assessed to be finite.



F-15

##### Table of Contents

Amortization

Intangible assets are amortized over the estimated useful lives of the related assets using the straight-line method as follows:



| |  |  | Technology 20 years;
| | - |  | --------------------



| |  |  | Customer relationships 25 years; and
| | - |  | ------------------------------------



| |  |  | Softwares 35 years.
| | - |  | --------------------

Impairment tests for property, plant and equipment and intangible assets

Property, plant and equipment and intangible assets subject to amortization are reviewed for impairment if there is any indication that the carrying
amount of the asset (or cash-generating unit to which it belongs) may not be recoverable. The recoverable amount is based on the higher of fair value less cost of disposal (market value) and value in use (determined using estimates of discounted
future net cash flows of the asset or group of assets to which it belongs).

Any impairment loss is recognized in the line Impairment in the
Consolidated Income Statement.

Financial instruments

(i) Financial assets

Financial assets
are classified either: (a) at fair value through profit or loss, or as (b) loans and receivables. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of
Constelliums financial assets at initial recognition.



|(a) | At fair value through profit or loss: These are financial assets held for trading. A financial asset is classified in this category if it is acquired principally for the purpose of selling in the short term. Derivatives
are also categorized as held for trading except when they are designated as hedging instruments in a hedging relationship that qualifies for hedge accounting in accordance with IAS 39, Financial instruments. Assets in this category are
classified as current assets if expected to be settled within 12 months; otherwise, they are classified as non-current. Financial assets carried at fair value through profit or loss, are initially recognized at fair value and transaction costs are
expensed in the Consolidated Income Statement.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b) | Loans and receivables: These are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are classified as current or non-current assets based on their maturity
date. Loans and receivables are comprised of trade receivables and other and non-current and current loans receivable in the Consolidated Statement of Financial Position. Loans and receivables are carried at amortized cost using the effective
interest rate method, less any impairment.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(ii) Financial liabilities

Borrowings and other financial liabilities (excluding derivative liabilities) are recognized initially at fair value, net of transaction costs incurred
and directly attributable to the issuance of the liability. These financial liabilities are subsequently measured at amortized cost using the effective interest rate method. Any difference between the amounts originally received (net of transaction
costs) and the redemption value is recognized in the Consolidated Income Statement using the effective interest rate method.



F-16



---

##### Table of Contents

(iii) Derivative financial instruments

Derivatives that are classified as held for trading are initially recognized at their fair value on the date at which the derivative contract is entered
into and are subsequently remeasured to their fair value at the date of each Consolidated Statement of Financial Position, with the changes in fair value included in Other (losses) / gainsnet. The Group has no derivatives designated for hedge
accounting treatment, except at December 31, 2014 for forward derivatives contracted to hedge the foreign currency risk on the estimated U.S. Dollar purchase price of the Wise entities (see NOTE 24Financial Instruments).

(iv) Fair value

Fair value is the
price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, relevant market prices are used to determine fair values. The Group
periodically estimates the impact of credit risk on its derivatives instruments aggregated by counterparties and takes it into account when estimating the fair value of its derivatives.

Credit Value Adjustments are calculated for asset derivatives based on Constellium counterparties credit risk. Debit Value Adjustments are calculated
for credit derivatives based on Constellium own credit risk.

The fair value method used is based on historical probability of default, provided by
leading rating agencies.

(v) Offsetting financial instruments

Financial assets and liabilities are offset and the net amount reported in the Consolidated Statement of Financial Position when there is a legally
enforceable right to offset the recognized amounts and there is an intention to settle on a net basis or realize the asset and settle the liability simultaneously.

Leases

Constellium as the lessee

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Various
buildings, machinery and equipment from third parties are leased under operating lease agreements. Under such operating lease agreements, the total lease payments are recognized as rent expense on a straight-line basis over the term of the lease
agreement, and are included in Cost of sales or Selling and administrative expenses, depending on the nature of the leased assets.

Leases of
property, plant and equipment where the Group has substantially all the risks and rewards of ownership are classified as finance leases. Various equipment from third parties are leased under finance lease agreements. Under such finance leases, the
asset financed is recognized in Property, plant and equipment and the financing is recognized as a financial liability, in Borrowings.

Constellium as the lessor

Certain
land, buildings, machinery and equipment are leased to third parties under finance lease agreements. During the period of lease inception, the net book value of the related assets is removed from Property, plant and equipment and a Finance lease
receivable is recorded at the lower of the fair value and the aggregate future cash payments to be received from the lessee computed at an interest rate implicit in the lease. As the Finance lease receivable from the lessee is due, interest income
is recognized.

##### Table of Contents

Inventories

Inventories are valued at the lower of cost and net realizable value, primarily on a weighted-average cost basis.

Weighted-average costs for raw materials, stores, work in progress and finished goods are calculated using the costs experienced in the current period
based on normal operating capacity (and include the purchase price of materials, freight, duties and customs, the costs of production, which includes labor costs, materials and other expenses, which are directly attributable to the production
process and production overheads).

Trade accounts receivable

Recognition and measurement

Trade
accounts receivable are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less provision for impairment (if any).

Impairment

An impairment allowance of
trade receivables is established when there is objective evidence that the Group will not be able to collect all amounts due. Indicators of impairment would include financial difficulties of the debtor, likelihood of the debtors insolvency,
late payments, default or a significant deterioration in creditworthiness. The amount of the provision is the difference between the assets carrying value and the present value of the estimated future cash flows, discounted at the original
effective interest rate. The expense (income) related to the increase (decrease) of the impairment allowance is recognized in the Consolidated Income Statement. When a trade receivable is deemed uncollectible, it is written off against the
impairment allowance account. Subsequent recoveries of amounts previously written off are credited in Cost of sales in the Consolidated Income Statement

Factoring arrangements

In a
non-recourse factoring arrangement, where the Group has transferred substantially all the risks and rewards of ownership of the receivables, the receivables are derecognized from the Consolidated Statement of Financial Position. Where trade accounts
receivable are sold with limited recourse, and substantially all the risks and rewards associated with these receivables are not transferred, receivables continue to be included in the Consolidated Statement of Financial Position. Inflows and
outflows from factoring agreements in which the Group does not derecognize receivables are presented on a net basis as cash flows from financing activities. Arrangements in which the Group derecognizes receivables result in changes in trade
receivables which are reflected as cash flows from operating activities.

Cash and cash equivalents

Cash and cash equivalents are comprised of cash in bank accounts and on hand, short-term deposits held on call with banks and other short-term highly
liquid investments with original maturities of three months or less that are readily convertible into known amounts of cash and which are subject to insignificant risk of changes in value, less bank overdrafts that are repayable on demand, provided
there is a right of offset.

Share capital

Ordinary
shares are classified as equity. Incremental costs directly attributable to the issue of new ordinary shares or options are shown in equity as a deduction, net of tax, from the proceeds.

##### Table of Contents

Trade payables

Trade payables are initially recorded at fair value and classified as current liabilities if payment is due in one year or less.

Provisions

Provisions are recorded for the best estimate of
expenditures required to settle liabilities of uncertain timing or amount when management determines that a legal or constructive obligation exists as a result of past events, it is probable that an outflow of resources will be required to settle
the obligation, and such amounts can be reasonably estimated. Provisions are measured at the present value of the expected expenditures to be required to settle the obligation.

The ultimate cost to settle such liabilities is uncertain, and cost estimates can vary in response to many factors. The settlement of these liabilities
could materially differ from recorded amounts. In addition, the expected timing of expenditure can also change. As a result, there could be significant adjustments to provisions, which could result in additional charges or recoveries affecting
future financial results.

Types of liabilities for which the Group establishes provisions include:

Close down and restoration costs

Estimated close down and restoration costs are accounted for in the year when the legal or constructive obligation arising from the related disturbance
occurs and it is probable that an outflow of resources will be required to settle the obligation. These costs are based on the net present value of estimated future costs. Provisions for close down and restoration costs do not include any additional
obligations which are expected to arise from future disturbance. The costs are estimated on the basis of a closure plan including feasibility and engineering studies, are updated annually during the life of the operation to reflect known
developments (e.g. revisions to cost estimates and to the estimated lives of operations) and are subject to formal review at regular intervals each year.

The initial closure provision together with subsequent movements in the provisions for close down and restoration costs, including those resulting from
new disturbance, updated cost estimates, changes to the estimated lives of operations and revisions to discount rates are capitalized within Property, plant and equipment. These costs are then depreciated over the remaining useful lives of the
related assets. The amortization or unwinding of the discount applied in establishing the net present value of the provisions is charged to the Consolidated Income Statement as a financing cost in each accounting year.

Environmental remediation costs

Environmental remediation costs are accounted for based on the estimated present value of the costs of the Groups environmental clean-up
obligations. Movements in the environmental clean-up provisions are presented as an operating cost within Cost of sales. Remediation procedures may commence soon after the time at which the disturbance, remediation process and estimated remediation
costs become known, and can continue for many years depending on the nature of the disturbance and the technical remediation.

Restructuring
costs

Provisions for restructuring are recorded when Constelliums management is demonstrably committed to the restructuring plan and
where such liabilities can be reasonably estimated. The Group



F-19

##### Table of Contents

recognizes liabilities that primarily include one-time termination benefits, or severance, and contract termination costs, primarily related to equipment and facility lease obligations. These
amounts are based on the remaining amounts due under various contractual agreements, and are periodically adjusted for any anticipated or unanticipated events or changes in circumstances that would reduce or increase these obligations.

Legal, tax and other potential claims

Provisions for legal claims are made when it is probable that liabilities will be incurred and when such liabilities can be reasonably estimated. For
asserted claims and assessments, liabilities are recorded when an unfavorable outcome of a matter is deemed to be probable and the loss is reasonably estimable. Management determines the likelihood of an unfavorable outcome based on many factors
such as the nature of the matter, available defenses and case strategy, progress of the matter, views and opinions of legal counsel and other advisors, applicability and success of appeals, process and outcomes of similar historical matters, amongst
others. Once an unfavorable outcome is considered probable, management weights the probability of possible outcomes and the most reasonable loss is recorded. Legal matters are reviewed on a regular basis to determine if there have been changes in
managements judgment regarding the likelihood of an unfavorable outcome or the estimate of a potential loss. Depending on their nature, these costs may be charged to Cost of sales or Other gains/ (losses)net in the Consolidated Income
Statement. Included in other potential claims are provisions for product warranties and guarantees to settle the net present value portion of any settlement costs for potential future legal actions, claims and other assertions that may be brought by
Constelliums customers or the end-users of products. Provisions for product warranty and guarantees are charged to Cost of sales in the Consolidated Income Statement. In the accounting year when any legal action, claim or assertion related to
product warranty or guarantee is settled, the net settlement amount incurred is charged against the provision established in the Consolidated Statement of Financial Position. The outstanding provision is reviewed periodically for adequacy and
reasonableness by Constellium management.

Management establishes tax reserves and accrues interest thereon, if deemed appropriate; in expectation
that certain tax return positions may be challenged and that the Group might not succeed in defending such positions, despite managements belief that the positions taken were fully supportable.

Pension, other post-employment healthcare plans and other long term employee benefits

Payments to defined contribution retirement benefit plans are recognized as an expense when employees have rendered service entitling them to the
contributions. Constelliums contributions to defined contribution pension plans are charged to the Consolidated Income Statement in the year to which the contributions relate. This expense is included in Cost of sales, Selling and
administrative expenses or Research and development expenses, depending on its nature.

For defined benefit plans, the retirement benefit obligation
recognized in the Consolidated Statement of Financial Position represents the present value of the defined benefit as reduced by the fair value of plan assets. The effects of changes in actuarial assumptions and experience adjustments are charged or
credited to Other comprehensive income / (loss).

The amount charged to the Consolidated Income Statement in respect of these plans (including the
service costs and the effect of any curtailment or settlement, net of interest costs) is included within the Income / (loss) from operations.

The
defined benefit obligations are assessed in accordance with the advice of qualified actuaries. The most significant assumption used in accounting for pension plans is the discount rate.

##### Table of Contents

Post-employment benefit plans relate to health and life insurance benefits to retired employees and in some
cases to their beneficiaries and covered dependants. Eligibility for coverage is dependent upon certain age and service criteria. These benefit plans are unfunded and are accounted for as defined benefit obligations, as described above.

Other long term employee benefits include jubilees and other long-term disability benefits. For these plans, actuarial gains and losses arising in the
year are recognized immediately in the Consolidated Income Statement.

Taxation

The current Income tax (expense) / benefit is calculated on the basis of the tax laws enacted or substantively enacted at the Consolidated Statement of
Financial Position date in the countries where the Company and its subsidiaries operate and generate taxable income.

The Group is subject to income
taxes in the Netherlands, France, United States and numerous other jurisdictions. Certain of Constelliums businesses may be included in consolidated tax returns within the Company. In certain circumstances, these businesses may be jointly and
severally liable with the entity filing the consolidated return, for additional taxes that may be assessed.

Deferred income tax assets and
liabilities are recognized for the estimated future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. This approach also
requires the recognition of deferred income tax assets for operating loss carryforwards and tax credit carryforwards.

The effect on deferred tax
assets and liabilities of a change in tax rates and laws is recognized as tax income /(loss) in the year when the rate change is substantively enacted. Deferred income tax assets and liabilities are measured using tax rates that are expected to
apply in the year when the asset is realized or the liability is settled, based on the tax rates and laws that have been enacted or substantively enacted at the date of the Consolidated Statement of Financial Position. Deferred income tax assets are
recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized.

Presentation of financial statements

The consolidated
financial statements are presented in millions of Euros. Certain reclassifications may have been made to prior year amounts to conform to current year presentation or with IFRS requirements (see NOTE 32Disposals, Disposals Group classified as
held for sale).

2.7. Judgments in applying accounting policies and key sources of estimation uncertainty

Many of the amounts included in the consolidated financial statements involve the use of judgment and/or estimation. These judgments and estimates are
based on managements best knowledge of the relevant facts and circumstances, giving consideration to previous experience. However, actual results may differ from the amounts included in the consolidated financial statements. Key sources of
estimation uncertainty that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year include the items presented below.

Purchase Accounting

Business
combinations are recorded in accordance with IFRS 3, Business Combination using the acquisition method. Under this method, upon the initial consolidation of an entity over which the

##### Table of Contents

Group has acquired exclusive control, the identifiable assets acquired and the liabilities assumed are recognized at their fair value at the acquisition date.

Therefore, through a number of different approaches and with the assistance of external independent valuation experts, the Group identified what it
believes is the fair value of the assets and liabilities at the acquisition date. These valuations include a number of assumptions, estimations and judgments. Quantitative and qualitative information is further disclosed in NOTE 3Acquisition
of Wise entities.

Significant assumptions which were used in determining allocation of fair value included the following valuation approaches: the
cost approach, the income approach and the market approach which were determined based on cash flow projections and related discount rates, industry indices, market prices regarding replacement cost and comparable market transactions. While the
Company believes that the estimates and assumptions underlying the valuation methodologies were reasonable, different assumptions could have resulted in different fair values.

Impairment tests for goodwill, intangible assets and property, plant and equipment.

The determination of fair value and value in use of cash generating units or groups of cash generating units depends on a number of assumptions, in
particular market data, estimated future cash flows and the discount rate.

These assumptions are subject to risk and uncertainty. Any material
changes in these assumptions could result in a significant change in a cash generating-units recoverable value or a goodwill impairment. Details of the key assumptions applied are set out in NOTE 13Intangible assets (including goodwill)
and in NOTE 14Property, plant and equipment.

Pension, other post-employment benefits and other long-term employee benefits

The present value of the defined benefit obligations depends on a number of factors that are determined on an actuarial basis using a number of
assumptions. The assumptions used in determining the defined benefit obligations and net pension costs include the discount rate and the rate of future compensation increases. In making these estimates and assumptions, management considers advices
provided by external advisers, such as actuaries.

Any material changes in these assumptions could result in a significant change in employee
benefits expense recognized in the Consolidated Income Statement, actuarial gains and losses recognized in equity and prepaid and accrued benefits. Details of the key assumptions applied are set out in NOTE 21Pensions and other post-employment
benefit obligations.

Taxes

Significant judgment is sometimes required in determining the accrual for income taxes as there are many transactions and calculations for which the
ultimate tax determination is uncertain during the ordinary course of business. The Group recognizes liabilities based on estimates of whether additional taxes will be due. Where the final tax outcome of these matters is different from the amounts
that were recorded, such differences will impact the current and deferred income tax provisions, results of operations and possibly cash flows in the year in which such determination is made.

Management judgment is required to determine the extent to which deferred tax assets can be recognized. In assessing the recognition of deferred tax
assets, management considers whether it is more likely than not that the deferred tax assets will be utilized. The deferred tax assets will be ultimately utilized to the extent that sufficient taxable profits will be available in the periods in
which the

temporary differences become deductible. This assessment is conducted through a detailed review of deferred tax assets by jurisdiction and takes into account the scheduled reversals of taxable
and deductible temporary differences, past, current and expected future performance deriving from the budget, the business plan and tax planning strategies. Deferred tax assets are not recognized in the jurisdictions where it is less likely than not
that sufficient taxable profits will be available against which the deductible temporary differences can be utilized.

Provisions

Provisions have been recorded for: (a) close-down and restoration costs; (b) environmental remediation and monitoring costs;
(c) restructuring programs; (d) legal and other potential claims including provisions for product income tax risks, warranty and guarantees, at amounts which represent managements best estimates of the expenditure required to settle
the obligation at the date of the Consolidated Statement of Financial Position. Expectations are revised each year until the actual liability is settled, with any difference accounted for in the year in which the revision is made. Main assumptions
used are described in NOTE 22Provisions.

Note 3Acquisition of Wise Entities

On January 5, 2015, Constellium acquired 100% of Wise Metals Intermediate Holdings LLC (Wise or Muscle Shoals), a private
aluminum sheet producer located in Muscle Shoals, Alabama, United States of America. The total consideration, paid in cash, was 370 million. With the acquisition, Constellium has now access to
450,000 metric tons (kt) of hot mill capacity from the widest strip mill in North America, reinforcing its position on the can market and positioning Constellium to continue to grow in the North American Body in White (BiW) market.

In accordance with IFRS 3, Business Combination, Constellium has recognized the assets acquired and liabilities assumed, measured, with the
assistance of an independent expert, at fair value at the acquisition date:

The valuation resulted in the recognition of intangible assets such as Customer relationships and
Technology. Property, plant and equipment, Inventories, Provisions and Borrowings have been remeasured at fair value. The resulting 395 million goodwill is mainly supported by the growing
automotive markets (Body in White) in North America. The resulting goodwill will be deductible for tax purposes.

Considering the industries served,
its major customers and product lines, Muscle Shoals and its related assets and liabilities are included in Packaging and Automotive Rolled Products (P&ARP) operating segment.

The combined revenue and net income for the year ended December 31, 2015 assuming the business combination occurred on January 1, 2015 would
not be materially different from the actual consolidated revenue (as the acquisition was completed on January 5, 2015).

Acquisition costs were
recognized as expenses in Other gains/ (losses)-net of Groups Consolidated Income Statement (34 million in 2014 and 5 million in
2015).

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

|(D) | For the year ended December 31, 2015, manufacturing system and process transformation costs related to supply chain reorganization mainly in our A&T operating segment.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(E) | Wise one-time costs related to the acquisition include :
|--- | --------------------------------------------------------



| |  |  | Wise Mid-West premium losses: Constellium seeks to achieve a full pass-through model for LME and premiums, primarily through contractual arrangements with metal suppliers and customers. At the acquisition date (January
5, 2015), not all Wise contracts had this pass-through mechanism. Constellium has renegotiated these contracts to bring them in line with its usual practice. In addition, the Mid West Premium market conditions were abnormal in the year ended
December 31, 2015 with premium falling from $524/metric ton as at January 5, 2015 to $198/metric ton as at December 31, 2015. This resulted in an un-recovered metal premium of 22
million.

| |  |  | Unwinding of Wise previous hedging policies: Constelliums policies are to hedge all known exposures. Losses of 4 million were incurred on the unwinding
of the predecessors hedging policies for the year ended December 31, 2015.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Effects of purchase accounting adjustment: Represents the non-cash step-up in inventory costs on the acquisition of Wise entities (12 million).

Our composite
statutory income tax rate of 38,2% in the year ended December 31, 2015, 31.0% in the year ended December 31, 2014 and of 36.0% in the year ended December 31, 2013 resulted from the statutory tax rates (i) in the United States of
40% in 2015, 43% in 2014 and 40% in 2013, (ii) in France of 38.0% in 2015, in 2014 and in 2013, (iii) in Germany of 29% in 2015, 2014 and 2013, (iv) in the Netherlands of 25% in 2015, 2014 and 2013 and (v) in Czech Republic of
19% in 2015, 2014 and 2013. The 7.2% increase in our composite tax rate from 2014 to 2015 and the 5.0% decrease in our composite tax rate from 2013 to 2014 resulted from the change in the weight of profits or losses in higher tax rate jurisdictions
most notably France and in the United States combined with the change in the weight of profits in lower tax rate jurisdictions most notably in Czech Republic in 2014.

|(A) | Based on the total number of all classes of shares (former A, B1 and B2) until the IPO on May 22, 2013, and on the total number of Class A ordinary shares from the IPO (See
NOTE 18Share Capital). Prior to the IPO, the Class B ordinary shares were included in the basic and diluted earnings per share calculation as the Class A and Class B ordinary shares had equal rights to profit allocation and dividends
and Class B ordinary shares, once issued, could not be repurchased nor cancelled by the Company without the consent of the holder. In connection with our IPO, the Management Equity Plan (MEP) was frozen so that there could be no
additional issuances or reallocations thereunder of Class B ordinary shares among MEP participants. In addition, from the date of the IPO, at the request of the MEP participants and in certain circumstances, the Company was committed to repurchase
these shares, and may subsequently cancel them (including the related accumulated rights to profit).

Accordingly, from the IPO date, Class B ordinary shares have been excluded from the calculation of the
weighted average number of ordinary shares used to calculate the basic earnings per share. As Class B ordinary shares are ultimately converted into Class A ordinary shares when the Company does not have to repurchase them, they are included in
the calculation of the weighted average number of ordinary shares used to calculate the diluted earnings per share.

All ordinary Class B shares were
cancelled in August 2015.



|(B) | For the years ended December 31, 2014 and 2013, includes B shares as they give rights to profit allocation and dividends and potential new ordinary shares to be issued as part of the Co-investment plan, the Equity
award plan, the Free Share and the Shareholding Retention Plan (See NOTE 31Share Equity Plan). All potential dilutive new ordinary shares were taken into account into the diluted earnings per share. There were no instrument excluded from the
computation of diluted earnings per share because their effect was antidilutive.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For the year ended December 31, 2015, there were
510,721 potential ordinary shares that could have a dilutive impact but were considered antidilutive due to negative earnings.

Impairment tests for goodwill

Goodwill in the amount of 443 million has been allocated to the Groups operating
segment Aerospace and Transportation (A&T) 5 million, Automotive Structures and Industry (AS&I)
2 million and Packaging and Automotive Rolled Products (P&ARP) 436 million.

At December 31, 2015, the recoverable amount of the A&T and AS&I operating segments has been determined based on value-in-use calculations
and significantly exceeded their carrying value. No reasonable change in the assumptions retained could lead to a potential impairment charge.

For
the P&ARP operating segment, the recoverable value was estimated by applying a discounted cash flow model and market participants assumptions. The expected future cash flows are based on the 2016-2025 medium and long term business plan
approved by the management and reviewed by the Board of Directors. They include the significant capital expenditures for the Body-in-White (up to 2020/2021) and the related returns. Considering the significant level of future capital expenditure
needed to address the Body in White market with the related Body in White cash inflows ramping-up from 2018/2019 and reaching a normative level in 2023/2024, cash flows were projected over a 10 year period. The terminal value assumes a normative
cash flow and a long term growth rate ranging from 0% to 2%. The discount rates applied to cash flows projections range between 11% and 12%. It was concluded that the carrying value did not exceed the recoverable value as at December 31, 2015.
Accordingly, the impairment test carried out at the P&ARP operating segment level did not lead to a goodwill impairment.

##### Table of Contents

Sensitivity analysis: the calculation of the recoverable value of the P&ARP operating segment is most
sensitive to the following assumptions:



| |  |  | Discount rate : an increase in the discount rate by 2% would result in the recoverable value equaling the carrying value;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | Perpetual growth rate : a decrease in the perpetual growth rate by 5 % would result in the recoverable value equaling the carrying value; or
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | BiW shipments : 40% lower shipments in the BiW US business would result in the recoverable value equaling the carrying value. Considering the overall size and length of the Body in White project, management determined
forecasted shipments and related revenues to be a key assumption.

Impairment tests for property, plant and equipment and intangibles assets

Muscle Shoals cash-generating unit: the following triggering events were identified as at December 31, 2015:



| |  |  | Continuing under performance and actual 2015 Muscle Shoals results showing a much lower financial performance than the initial business plan prepared as part of the Wise acquisition, and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Revised budget and strategic plan for Muscle Shoals downgraded, notably after taking into account new sale agreements commercial conditions for the can/packaging business.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In accordance with the accounting policies described in NOTE 2.6 of the Consolidated Financial Statements, the Muscle Shoals cash-generating unit was
tested for impairment as at December 31, 2015.

Its value-in-use was determined based on projected cash flows expected to be generated by the
can/packaging business at Muscle Shoals. These cash flow forecasts were prepared by the Group Management and reviewed by the Board of Directors. The discount rate applied to cash flows projections was 11% and cash flows beyond the projection period
have been extrapolated using a 0% growth rate. The value in use calculation led to a recoverable value being 400 million lower than the carrying value.

Management determined that the fair value less cost of disposal of Muscle Shoals cash-generating unit does not exceed the value in use.

Accordingly, an impairment charge of 400 million was recorded as at December 31, 2015,
reducing the Muscle shoals cash- generating unit intangible assets and property, plant and equipment.

Sensitivity analysis: the calculation
of the recoverable value of the Muscle Shoals cash-generating unit is most sensitive to the following assumptions:



| |  |  | Discount rate : a increase / decrease of the discount rate by 1% would impact the recoverable value by 40 million and
48 million respectively
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Perpetual growth rate : a increase / decrease of the perpetual growth rate by 1% would impact the recoverable value by 19 million and 16 million respectively.

Impairment allowance

The
Group periodically reviews its customers account aging, credit worthiness, payment histories and balance trends in order to evaluate trade accounts receivable for impairment. Management also considers whether changes in general economic
conditions and in the industries in which the Group operates in particular, are likely to impact the ability of the Groups customers to remain within agreed payment terms or to pay their account balances in full.

Revisions to the impairment allowance arising from changes in estimates are included as either additional allowance or recoveries, with the
corresponding expense or income included in Selling and administrative expenses. An impairment allowance amounting to 0.5 million was recognized during the year ended December 31, 2015
(0.5 million during the year ended December 31, 2014).

None of the other amounts
included in Other receivables was deemed to be impaired.

The maximum exposure to credit risk at the reporting date is the carrying value of each
class of receivable shown above. The Group does not hold any collateral from its customers or debtors as security.

16.2 Currency concentration

The composition of the carrying amounts of total Trade receivablesnet by currency is shown in Euro equivalents as follows:

16.3 Factoring arrangements

The Group factored specific accounts receivables in Germany, Switzerland, Czech Republic and France by entering into factoring agreements with third
parties for a maximum capacity of 350 million, allocated as follows:



| |  |  | 235 million for France

| |  |  | 115 million for Germany, Switzerland and Czech Republic
| | - |  | --------------------------------------------------------

During December 2015, the Group renegotiated the factoring arrangement for France, extending maturity to December 2018, reducing costs and changing the
recourse nature of the arrangement.

In addition, new factoring agreements were signed in the United States during the year ended December 31,
2015:



| |  |  | On March 23, 2015, Muscle Shoals entered into a Factoring Agreement which provides for the sale of specific accounts receivables. In October, the agreement was amended to provide a committed capacity of $100
million and an additional uncommitted capacity of $280 million. In December 2015, the Companys debt downgrade resulted in a termination of the commitment. As at December 31, 2015, the financial institution continued to purchase $100
million of accounts receivable on an uncommitted basis.

| |  |  | On December 15, 2015, Constellium Automotive USA entered into a Factoring agreement which provides for the sale of specific accounts receivables and for a maximum capacity of $25 million.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Under the Groups factoring agreements, most of the accounts receivables are now sold without recourse. Where the Group has transferred
substantially all the risks and rewards of ownership of the receivables, the receivables are de-recognized from the Consolidated Statement of Financial Position. Some remaining receivables do not qualify for derecognition under IAS 39,
Financial instruments: Recognition and Measurement, as the Group retains substantially all of the associated risks and rewards

Under
the agreements, as at December 31, 2015, the total carrying amount of the original assets factored is 529 million (December 31, 2014:
323 million) of which:



| |  |  | 429 million (December 31, 2014: 94 million) derecognized from the Consolidated Statement of Financial
Position as the Group transferred substantially all of the associated risks and rewards to the factor
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 100 million (December 31, 2014: 229 million) recognized on the Consolidated Statement of Financial
Position
| | - |  | -------------------------------------------------------------------------------------------------------------

At December 31, 2015 and December 31, 2014, there was no amount due to the factor relating to trade accounts
receivables sold.

Interest costs and other fees

During the year ended December 31, 2015, Constellium incurred 11 million in interest,
other fees and amortized deferred financing costs (9 million during the year ended December 31, 2014 and 10 million during the
year ended December 31, 2013) from these arrangements that are included in finance costs (see NOTE 10Finance CostsNet).

Under
certain of the factoring agreements entered into in 2011, the Group paid a one-time, up-front arrangement fee of 2.25% of the initial aggregate maximum financing amount of 300 million (for
both agreements), which totaled 7 million.

These arrangement fees plus an additional 7 million in legal and other fees related to the factoring agreements are being amortized as finance costs over a period of five years (see NOTE 10Finance CostsNet).

During the year ended December 31, 2015,
3 million of such costs were amortized as finance costs (2 million during the year ended December 31, 2014, and 3 million during the year December 31, 2013). At December 31, 2015, the Group had less than 1 million (3 million at December 31, 2014) of unamortized up-front and legal fees related to the factoring arrangements (included in deferred financing costs).

Covenants

At December 31, 2015, the factoring
arrangements contain certain affirmative and negative covenants, including relating to the administration and collection of the assigned receivables, the terms of the invoices and the exchange of information, but do not contain restrictive financial
covenants.

The Group was in compliance with all applicable covenants at December 31, 2015 and 2014.

Intercreditor agreement

On January 4, 2011, the
Group entered into an Intercreditor Agreement between the French, German and Swiss sellers of the Groups receivables under the various accounts receivable factoring programs described above and the purchasers of those receivables.

The intercreditor agreement was terminated in December 2015 and all rights and obligations of the parties covered by the intercreditor agreement were
terminated accordingly.

Deferred financing costs

The Group incurs certain financing costs with third parties associated with its factoring arrangements and U.S. Revolving Credit facility. Amortization
of these deferred finance costs is included in Finance costsnet in the Consolidated Income Statement.

Costs incurred and amortization
recognized throughout the periods presented are shown in the table below

Note 21 Pensions and Other Post-Employment Benefit Obligations

The Group operates a number of pensions, other post-employment benefits and other long-term employee benefit plans. Some of these plans are defined
contribution plans and some are defined benefit plans, with assets held in separate trustee-administered funds. Benefits paid through pension trusts are sufficiently funded to ensure the payment of benefits to retirees when they become due.

Actuarial valuation are carried out with the support of an independent expert and are reflected in the Consolidated Financial Statements as described in
NOTE 2.6Principles governing the preparation of the Consolidated Financial Statements.

21.1 Description of the plans

Pension plans

Constelliums
pension obligations are in the U.S., Switzerland, Germany and France. Pension benefits are generally based on the employees service and highest average eligible compensation before retirement and are periodically adjusted for cost of living
increases, either by company practice, collective agreement or statutory requirement.

Other post-employment benefits (OPEB)

The Group provides health care and life insurance benefits to retired employees and in some cases to their beneficiaries and covered dependents, mainly
in the U.S Eligibility for coverage is dependent upon certain age and service criteria. These benefit plans are unfunded.

##### Table of Contents

Other long-term employee benefits

Other long term employee benefits include jubilees in France, Germany and Switzerland and other long-term disability benefits in the U.S.

21.2 Description of risks

Our estimates of liabilities and
expenses for pensions and other post-employment benefits incorporate a number of assumptions, including discount rate, longevity estimate and inflation rate. The defined benefit obligations expose the Group to a number of risks, including longevity,
inflation, interest rate, medical cost inflation, investment performance, and change in law governing the employee benefit obligations. These risks are mitigated when possible by applying an investment strategy for the funded schemes which aims to
minimize the long-term costs. This is achieved by investing in a diversified selection of asset classes, which aims to reduce the volatility of returns and also achieves a level of matching with the underlying liabilities.

Investment performance risk

Our
pension plan assets consist primarily of funds invested in listed stocks and bonds (see NOTE 21.12-Fair value hierarchy).

The present value of
funded defined benefit obligations is calculated using a discount rate determined by reference to high quality corporate bond yields. If the return on plan asset is below this rate, it will increase the plan deficit.

Interest rate risk

A decrease in the
discount rate will increase the defined benefit obligation. At December 31, 2015, impacts of the change on the defined benefit obligation of a 0.50% increase / decrease in the discount rates are calculated by using a proxy based on the duration
of each scheme, as follows:

Longevity risk

The present value of the defined benefit obligation is calculated by reference to the best estimate of the mortality of plan participants. An increase in
the life expectancy of the plan participants will increase the plans liability.

21.3 Main events

In 2015, the acquisition of Wise resulted in an increase of 8 million in the Groups net
pension liability.

In 2014, the Swiss pension plan was modified to reflect updated conversion factors with transitional rates until 2022. This
amendment resulted in the immediate recognition of negative past service cost of 6 million.

##### Table of Contents

In 2013, 2014, the Group implemented certain plan amendments that had the effect of reducing benefits for
the participants in the Constellium Rolled Products Ravenswood Retiree Medical and Life Insurance Plan. These amendments resulted in the immediate recognition of negative past service cost of
9 million in 2014 and 11 million in 2013.

Effects of changes in foreign exchange rates

The appreciation of the U.S. Dollar and Swiss Francs against the Euro resulted in an increase of respectively 37 million and 6 million of the Group net defined benefit obligation for the year ended December 31, 2015.

21.4 Actuarial assumptions

|(A) | Other main financial assumptions used for the OPEB (healthcare plans, which are predominantly in the U.S.), were:
|--- | -----------------------------------------------------------------------------------------------------------------

| | Medical trend rate: pre 65: 7.00% starting in 2016 reducing to 4.50% by the year 2024 and post 65: 6.00% starting in 2016 grading down to 4.50% by 2024, and
|- | ------------------------------------------------------------------------------------------------------------------------------------------------------------

| | Claims costs based on individual company experience.
|- | ----------------------------------------------------

For both pension and healthcare plans, the
post-employment mortality assumptions allow for future improvements in life expectancy.

21.14 OPEB amendments

During
the third quarter of 2012, the Group implemented certain plan amendments that had the effect of reducing benefits of the participants in the Constellium Rolled Products Ravenswood Retiree Medical and Life Insurance Plan. In February 2013, five
Constellium retirees and the United Steelworkers union filed a class action lawsuit against Constellium Rolled Products Ravenswood, LLC in a federal district court in West Virginia, alleging that Constellium Rolled Products Ravenswood, LLC
improperly modified retiree health benefits.

The Group believes that these claims are unfounded, and that Constellium Rolled Products Ravenswood, LLC
had a legal and contractual right to make the applicable modification.

Close down, environmental and restoration costs

The Group records provisions for the estimated present value of the costs of its environmental clean-up obligations and close down and restoration
efforts based on the net present value of estimated future costs of the dismantling and demolition of infrastructure and the removal of residual material of disturbed areas, using an average discount rate of 1.1%. A change in the discount rate of
0.5% would impact the provision by 3 million.

It is expected that these provisions will be
settled over the next 40 years depending on the nature of the disturbance and the technical remediation plans.

and guarantees and 5 million in 2015 (6 million in 2014) related to late delivery penalties. These provisions are expected to be

|(C) | Since the early 1990s, certain activities of the Groups businesses have been subject to claims and lawsuits in France relating to occupational diseases resulting from alleged asbestos exposure, such as
mesothelioma and asbestosis. It is not uncommon for the investigation and resolution of such claims to go on over many years as the latency period for acquiring such diseases is typically between 25 and 40 years. For any such claim, it is up to the
social security authorities in each jurisdiction to determine if a claim qualifies as an occupational illness claim. If so determined, the Group must settle the case or defend its position in court. At December 31, 2015, 15 cases in which gross
negligence is alleged (faute inexcusable) remain outstanding (9 at December 31, 2014), the average amount per claim being less than 0.1 million. The average settlement
amount per claim in 2014 and 2013 was separately 0.3 and 0.1 million. It is not anticipated that the resolution of such litigation and
proceedings will have a material effect on the future results from continuing operations, financial condition, or cash flows of the Group.

Note 23 Financial Risk Management

The Groups financial risk management strategy focuses on minimizing the cash flow impacts
of volatility in foreign currency exchange rates, metal prices and interest rates, while maintaining the financial flexibility the Group requires in order to successfully execute the Groups business strategies.

Due to Constelliums capital structure and the nature of its operations, the Group is exposed to the following financial risks: (i) market
risk (including foreign exchange risk, commodity price risk and interest rate risk); (ii) credit risk and (iii) liquidity and capital management risk.

23.1 Market risk

(i) Foreign
exchange risk

Net assets, earnings and cash flows are influenced by multiple currencies due to the geographic diversity of sales and the
countries in which the Group operates. The Euro and the U.S. Dollar are the currencies in which the majority of sales are denominated. Operating costs are influenced by the currencies of those countries where Constelliums operating plants
are located and also by those currencies in which the costs of imported equipment and services are determined. The Euro and U.S. Dollar are the most important currencies influencing operating costs.

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

In June 2011, the Group entered into a five-year frame agreement with a major customer for the sale of fabricated metal
products in U.S. Dollars. In line with its hedging policy, the Group entered into significant foreign exchange derivative transactions to forward sell U.S. Dollars versus the Euro following the signing of the multiple-year frame agreement to match
these future sales.

At December 31, 2015, our largest commercial foreign exchange derivative transactions related to this contract.

The notional principal amounts of the outstanding commercial foreign exchange contracts at December 31, 2015with maturities ranging between
2016 and 2020were as follows:

A negative balance represents a net currency sale, whereas a positive balance represents a net currency purchase.

Except for limited non-recurring transactions, hedge accounting is not applied and therefore the mark-to-market impact is recorded in Other
gains/(losses)net or Finance costsnet.

For the year ended December 31, 2015, the impact of these derivatives was an unrealized
loss of 10 million as the U.S. dollar appreciated against the Euro in 2015. For the year ended December 31, 2014, the impact of these derivatives was an unrealized loss of 41 million. The offsetting gain related to the forecasted sales are not visible due to the sales not yet being recorded in the books of the Group.

As the U.S. dollar appreciates against the Euro, the derivative contracts entered into with financial institutions have a negative mark-to-market. Our
financial derivative counterparties require margin call should our mark-to-market exceed a pre-agreed contractual limit. In order to protect from the potential margin calls for significant market movements, the Group holds a significant liquidity
buffer in cash or

in availability under its various borrowing facilities, enters into derivatives with a large number of financial counterparties and monitors margin requirements on a daily basis for adverse
movements in the U.S. dollar versus the Euro.

At December 31, 2015 and 2014, the margin requirement related to foreign exchange hedges was
nil.

During 2012, the Group decided to limit the liquidity risk arising from potential margin calls on operational hedges by entering into a
portfolio of foreign exchange zero cost collars (combinations of bought calls and sold puts). In 2015, the Company decided to realize the option portfolio for a 3 million gain. At December
2015, there were no foreign exchange zero cost collars outstanding.

Borrowings are principally in U.S. dollars and Euros (see NOTE
19Borrowings). It is the policy of the Group to hedge all non-functional currency debt and cash. The Group entered into cross currency basis swaps to hedge the foreign exchange inherent in our financing. At December 31, 2015, the notional
outstanding on the cross currency basis swaps was $720 million (661 million). The unrealized gain related to these cross currency basis swaps amounted to
18 million during the year ended December 31, 2015.

Foreign exchange sensitivity: Risks
associated with exposure to financial instruments

A 10% weakening in the December 31, 2015, closing Euro exchange rate against all
applicable currencies on the value of financial instruments held by the Group at December 31, 2015, would have decreased earnings (before tax effect) as shown in the table below :

(ii) Commodity price risk

The Group is subject to the effects of market fluctuations in the price of aluminum, which is the Groups primary metal input and a significant
component of its output. The Group is also exposed to silver, copper and natural gas but in a less significant way.

The Group strategy is to
protect the Groups margin on future conversion and fabrication activities by aligning the price and quantity of physical aluminum purchases with that of physical aluminum sales. When the Group is unable to do so, it enters into derivative
financial instruments to pass through the exposure to metal price fluctuations to financial institutions at the time the price is set. Therefore, the Group purchases fixed price aluminum forwards to offset the exposure of LME volatility on its fixed
price sales agreements for the supply of metal.

The Group does not apply hedge accounting and therefore any mark-to-market movements are recognized
in Other gains / (losses)net.

At December 31, 2015, the notional principal amount of aluminum derivatives outstanding was 167,925 tons
(approximately $282 million)133,875 tons at December 31, 2014, (approximately $269 million)with maturities ranging from 2016 to 2019, copper derivatives outstanding was 1,750 tons (approximately $14 million)3,000 tons at
December 31, 2014 (approximately $24 million)with maturities in 2016, silver derivatives 619,981 ounces (approximately $9 million)270,027 ounces at December 31, 2014 (approximately $6 million)with maturities in 2016 and
7,200,000 MMBtu of natural gas futures (approximately $23 million)3,465,000 MMBtu at December 31, 2014 (approximately $13 million) with maturities in 2016.

The value of the contracts will fluctuate due to changes in market prices but is intended to help protect the Groups margin on future conversion
and fabrication activities. At December 31, 2015, these contracts are directly with external counterparties.

For the year ending
December 31, 2015, 7 million of unrealized losses were recorded in relation to LME Aluminum futures due to a decline in the LME price of aluminum, with the revaluation of the
underlying transaction continuing partially off- balance sheet for the sales which had not yet been invoiced and recognized as revenue. Unrealized losses for other commodities amount to 2
million. For the year ending December 31, 2014, 7 million of unrealized losses were recorded in relation to LME futures.

As the LME price for aluminum falls, the derivative contracts entered into with financial institution counterparties have a negative mark-to-market. The
Groups financial institution counterparties may require margin calls should the negative mark-to-market exceed a pre-agreed contractual limit. In order to protect from the potential margin calls for significant market movements, the Group
enters into derivatives with a large number of financial counterparties and monitors margin requirements on a daily basis for adverse movements in aluminum prices.

At December 31, 2015 and 2014, the margin requirement related to aluminum or any other commodity hedges was nil.

Commodity price sensitivity: risks associated with derivatives

The net impact on earnings and equity of a 10% increase or decrease in the market price of aluminum, based on the aluminum derivatives held by the Group
at December 31, 2015 (before tax effect), with all other variables held constant was estimated to 23 million gains or losses (20
million at December 31, 2014). The balances of such financial instruments may change in future periods however, and therefore the amounts shown may not be indicative of future results.

(iii) Interest rate risk

Interest rate risk refers to the risk that the value of financial instruments held by the Group and that are subject to variable rates will fluctuate, or
the cash flows associated with such instruments will be impacted due to changes in market interest rates. The Groups interest rate risk arises principally from borrowings. Borrowings issued at variable rates expose the Group to cash flow
interest rate risk which is partially offset by cash and cash equivalents deposits (including short-term investments) earning interest at variable interest rates. Borrowings issued at fixed rates expose the Group to fair value interest rate risk.

Interest rate sensitivity: risks associated with variable-rate financial instruments

The impact on Loss/Income before income tax for the period of a 50 basis point increase or decrease in the LIBOR or EURIBOR interest rates, based on the
variable rate financial instruments held by the Group at December 31, 2015, with all other variables held constant, was estimated to be less than 1 million for the periods ended
December 31, 2015 and December 31, 2014. However, the balances of such financial instruments may not remain constant in future periods, and therefore the amounts shown may not be indicative of future results. At December 2015, 92% of
Groups borrowings were at fixed rate.

23.2 Credit risk

Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss.
The Group is exposed to credit risk with financial institutions and other parties as a result of cash-in-bank, cash deposits, mark-to-market on derivative transactions and customer trade receivables arising from Constelliums operating
activities. The maximum exposure to credit risk at the reporting date is the carrying value of each class of financial asset as described in NOTE 24Financial Instruments. The Group does not generally hold any collateral as security.

Credit risk related to transactions with financial institutions

Credit risk with financial institutions is managed by the Groups Treasury department in accordance with a Board approved policy. Constellium
management is not aware of any significant risks associated with financial institutions as a result of cash and cash equivalents deposits (including short-term investments) and financial derivative transactions.

The number of financial counterparties is tabulated below showing our exposure to the counterparty by rating type (Parent company ratings from

Credit risks related to customer trade receivables

The Group has a diverse customer base geographically and by industry. The responsibility for customer credit risk management rests with Constellium
management. Payment terms vary and are set in accordance with practices in the different geographies and end-markets served. Credit limits are typically established based on internal or external rating criteria, which take into account such factors
as the financial condition of the customers, their credit history and the risk associated with their industry segment. Trade receivables are actively monitored and managed, at the business unit or site level. Business units report credit exposure
information to Constellium management on a regular basis. Over 80% of the Groups trade account receivables are insured by insurance companies rated A34 or better. In situations where
collection risk is considered to be above acceptable levels, risk is mitigated through the use of advance payments, bank guarantees or letters of credit. Historically, we have a very low level of customer default as a result of long history of
dealing with our customer base and an active credit monitoring function.

See NOTE 16Trade Receivables and other for the aging of trade
receivables.

23.3 Liquidity and capital risk management

Groups capital structure includes shareholders equity, borrowings and various third-party financing arrangements (such as credit facilities
and factoring arrangements). Constelliums total capital is defined as total equity plus net debt. Net debt includes borrowings due to third parties less cash and cash equivalents.

Constelliums overriding objectives when managing capital are to safeguard the business as a going concern, to maximize returns for its owners and
to maintain an optimal capital structure in order to minimize the weighted cost of capital.

All activities around cash funding, borrowings and
financial instruments are centralized within Constelliums Treasury department. Direct external funding or transactions with banks at the operating plant entity level are generally not permitted, and exceptions must be approved by
Constelliums Treasury department.

The liquidity requirements of the overall Company are funded by drawing on available credit facilities,
while the internal management of liquidity is optimized by means of cash pooling agreements and/or intercompany loans and deposits between the Companys operating entities and central Treasury.

The contractual agreements that the Group has with derivative financial counterparties require the posting of collateral once a certain threshold has
been reached. In order to protect the Group from the potential margin calls for significant market movements, the Group holds a significant liquidity buffer in cash or availability under its various borrowing facilities, enters into derivatives with
a large number of financial counterparties, entered into a series of zero cost collars (see NOTE 23.1 (i)) and monitors margin requirements on a daily basis for adverse movements in the U.S. dollar versus the Euro and in aluminum prices.

In excess of the cash in bank (See NOTE 17Cash and Cash equivalents), the Group has access to
261 million undrawn facilities (including the 145m Constellium N.V. unsecured credit facility) at December 31, 2015.

##### Table of Contents

24.2 Fair values

All the derivatives are presented at fair value in the balance sheet.

The carrying value of the Groups borrowings is the redemption value at maturity.

The fair value of Constellium N.V. December 2014 and May 2014 Senior Notes account for respectively 80% and 72 % of the nominal value and amount
respectively to 487 million and 482 million at December 31, 2015.

The fair value of Muscle Shoals Senior Secured Notes and Senior PIK Toggle Notes account for 67% of the nominal value and amount to 490 million at December 31, 2015.

The fair values of other financial assets and
liabilities approximate their carrying values, as a result of their liquidity or short maturity.

24.3 Margin calls

Constellium Finance S.A.S and Constellium Switzerland A.G. entered into agreements with some financial institutions in order to define applicable rules
with regards to the setting-up of derivative trading accounts. On a daily or weekly basis (depending on the arrangement with each financial institution), all open currency or metal derivative contracts are revalued to the current market price. When
the change in fair value reaches a certain threshold (positive or negative), a margin call occurs resulting in the Group making or receiving back a cash payment to/from the financial institution.

The cash deposit related to margin calls made by the Group is nil at December 31, 2015 and 2014.

24.4 Valuation hierarchy

The following table provides an
analysis of financial instruments measured at fair value, grouped into levels based on the degree to which the fair value is observable:



| |  |  | Level 1 valuation is based on quoted price (unadjusted) in active markets for identical financial instruments, it includes aluminum futures that are traded on the LME;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 2 valuation is based on inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities, either directly (i.e. prices) or indirectly (i.e. derived from prices), it
includes foreign exchange derivatives.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3 valuation is based on inputs for the asset or liability that are not based on observable market data (unobservable inputs)
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------

Based on the expected taxable income of the entities, the Group
believes that it is more likely than not that a total of 1,160 million (599 million at December 31, 2014) of unused tax losses
and deductible temporary differences will not be used. Consequently, net deferred tax assets have not been recognized. The related tax impact of 369 million (193 million at December 31, 2014) is attributable to the following:

Substantially all of the tax losses not expected to be used reside in the Netherlands, the United States
and in Switzerland.

The holding companies in the Netherlands have been generating tax losses over the past four years, and these holding companies
are not expected to generate sufficient qualifying taxable profits in the foreseeable future to utilize these tax losses before they expire in the years from 2020 to 2023.

The tax losses not expected to be utilized in the United States relate to one of our main operating entities. Although this entity is expected to be
profitable in the medium or long term, considering notably the anticipated development of the Body-in-White business, it bears significant non-cash depreciation and financial interests that will continue generating tax losses in the coming years.
Accordingly, it is uncertain whether the entity will be able to use, at its level given the absence of an overall U.S. tax group, these tax losses before they expire. Consequently, the related deferred tax assets have not been recognized.

The tax losses not expected to be utilized in Switzerland relate to losses generated by one of our Swiss entities that will expire in the years from
2019 to 2022. In the context of the 2015 restructuring and impairment of assets, this Swiss entity is not expected to generate sufficient taxable profits over the next coming years to utilize these losses before they expire.

As at December 31, 2015, most of the unrecognized deferred tax assets on deductible temporary differences on long-term assets and other differences
relate to the U.S. and Swiss entities discussed above. A joint assessment has been performed on the recoverability of the deferred tax assets on deductible temporary differences and tax losses for these two entities. In line with the assessments,
the related deferred tax assets on long term assets and on other differences have not been recognized.

As at December 31, 2014, most of the
unrecognized deferred tax assets on deductible temporary differences on pension related to another of our U.S. main operating entities. As at December 31, 2015 and to assess the recoverability of these deferred tax assets, we again carefully
considered the available positive and negative evidence, and determined that positive evidences (such as recent, actual and future expected profits or stabilized industrial performance improving our long term visibility on future operating profits)
over-weighted negative evidences (such as previous history of operating losses). Accordingly, the related long term deferred tax assets have been fully recognized.

Note 31Share Equity Plans

Share based payment

Management equity plan (MEP)

In 2011, the Company implemented a MEP for Constellium management in order to align their interests with the ones of the shareholders and to enable the
selected managers to participate in the long-term growth of Constellium. In 2014, the accelerated vesting of the remaining non-vested portion of the Class B ordinary shares was approved and the fully vested Class B ordinary shares were converted
into Class A ordinary shares.

Restricted stock unit (RSU) plans

Free share plan

In 2013, a free share plan was granted to all
employees in the U.S., France, Germany, Switzerland and the Czech Republic. Under this plan, each eligible employee was granted an award of 25 RSU that will vest and be settled in Class A ordinary shares on the second anniversary of our initial
public offering, subject to the applicable employee remaining employed by the Company or its subsidiaries through that date.

The plan vested in May
2015 and accordingly 185,285 shares were issued and granted to our employees.

Shareholding Retention Plan

In 2013, a shareholding retention plan was implemented in order to encourage critical members of our senior management to maintain a significant portion
of their current investment under the Companys MEP.

Beneficiaries of the MEP were awarded a one-time retention award consisting of a grant of
RSU with a grant date value equal to a specified percentage of the recipients annual base salary. The RSU will be settled for our Class A ordinary shares on the second anniversary of the date of grant, subject to the recipient remaining
continuously employed within the Group through that date and, for MEP participants, subject to the retention of at least 75% of interest in Class A ordinary shares for MEP participants.

The October 2013 plan vested in October 2015 and accordingly 363,842 shares were issued and granted to our employees.

Eleven employees were granted 84,000 and 50,000 RSU in 2014 and 2015 respectively. These RSU will vest 100% after a 2-year period if the employees are
continuously employed from the grant date through the end of the 2-year period.

In April 2015, 33 employees were granted 195,500 RSU. These RSU
will vest 100% after a 3-year period if the employees are continuously employed from the grant date through the end of the 3-year period.

Equity Awards Plan

In May 2013, two non-employee directors were granted an award of 8,816 RSU. The service vesting tranche vests 50% on each anniversary date of
the equity award grant date.

In June 2014, four board members were granted an award of 8,820 RSU. The service vesting tranche vests 50% on each
anniversary date of the equity award grant date.

In June 2015, nine board members were granted an award of 29,202 RSU. The service vesting tranche
vests 50% on each anniversary date of the equity award grant date.

Co-investment Plan

In March 2014, the Company provided the opportunity to selected managers to invest part of their 2013 bonus paid in 2014 and to enter into a
co-investment plan.

The selected managers who effectively decided to invest part of their bonus into ordinary shares, were granted performance
based RSU in an amount equal to a specified multiple (the vesting multiplier) of ordinary shares (71,490) invested as part of this plan. These performance RSU will vest after a two year period from grant date if the three following
conditions are simultaneously met:



| |  |  | The performance condition is Total Shareholder Return (TSR) related as the vesting multiplier will be in a range from 0 to 7 depending on the TSR evolution over the 2-year vesting period;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The selected managers must be continuously employed by the Company through the end of the 2-year vesting period; and
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | The selected managers who have invested into this co-investment plan must continue to hold 100% of the shares they initially purchased through this plan until the end of the 2-year vesting period.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

In July 2015, the Company informed the participants that they are offered the opportunity to extend by one
year (to May 2017) the reference period.

Performance share plan

In June 2015, ten employees were granted 194,000 performance based RSU and in November 2015, 385 employees were granted 829,000 performance-based RSU.

These performance based RSU will vest after a 3-year period from grant date if the two following conditions are simultaneously met:



| |  |  | The performance condition is Total Shareholder Return (TSR) related as the vesting multiplier will be in a range from 0 to 3 depending on the TSR evolution over the 3-year vesting period;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The selected managers must be continuously employed by the Company through the end of the 3-year vesting period.
| | - |  | ----------------------------------------------------------------------------------------------------------------

Expense recognized during the year

In accordance with IFRS
2, an expense is recognized over the vesting period. The estimate of this expense is based upon the fair value of a Class A potential ordinary share at the grant date.

The total expense related to the potential ordinary shares for the year ended December 31, 2015, 2014 and 2013 amounted to 5 million, 4 million and 2 million respectively.
