Overview

We are a global leader in the development, manufacture and sale of a broad range of high value-added specialty rolled

and extruded aluminum products to the aerospace, space, defense, packaging, automotive, commercial transportation and

general industrial end-markets. Our business model is to add value by converting aluminum into semi-fabricated and in some

instances fully-fabricated alloyed aluminum products which meet stringent and performance-critical requirements from our

customers. Our product portfolio generally commands higher margins as compared to less differentiated, more commoditized

aluminum products. Our business model aims to pass through aluminum price exposure by pricing our products to include the

cost of the metal purchased and hedging any remaining exposure to achieve aluminum price neutrality.

At December 31, 2025, we have 24 manufacturing facilities, 3 Research and Development (“R&D”) centers, and 3

administrative centers. Our portfolio of flexible, integrated and strategically located facilities is well invested, technologically

advanced and competitively positioned. We believe that we are a critical supplier to many of our customers given our world-

class technological and R&D capabilities, our intellectual property and more than 50 years of manufacturing experience. Many

of our products are technically advanced, requiring long and complex qualification processes as well as the need for close

customer collaborations including joint product development. We believe that our strategic footprint, differentiated capabilities,

technically advanced product portfolio, integrated approach and long-standing customer relationships are difficult to replicate

and support our competitive position.

Our Strategy

Our mission is to meet customers’ and society’s need for lightweight, strong and sustainable aluminum products while

generating attractive returns for our shareholders. We aim to achieve our mission by expanding our leading position as an

innovative, go-to-supplier of technologically advanced fabricated aluminum solutions. We are committed to building a safe and

sustainable company and becoming the most exciting company in our industry. To achieve these objectives, we have built a

business strategy centered around six core principles:

(i) Focus on High Value-added and Responsible Products

We are primarily focused on our strategic end-markets including aerospace, packaging and automotive, in which we have

leading positions and long-standing relationships with many of the key manufacturers. These are also markets where we believe

we can differentiate ourselves through our high value-added and specialty products which make up the majority of our product

portfolio. Because aluminum is lightweight, strong, durable, and infinitely recyclable, we have invested heavily in advancing

our manufacturing and recycling capabilities. These improvements deliver products that reduce weight, increase strength, and

improve formability, helping customers meet their carbon‑reduction objectives.

(ii) Increase Customer Connectivity

We regard our relationships with our customers as partnerships in which we work closely together to develop technically

advanced and customized solutions. We aim to deepen our ties with our customers by consistently providing best-in-class

products and services and engaging in joint product development projects. In addition, supply chain integration allows us to

better anticipate customer demands and more efficiently manage our working capital needs. We also seek to strengthen

customer connectivity through customer technical support and closed-loop scrap recycling programs.

(iii) Optimize Margins and Asset Utilization Through Rigorous Product Portfolio Management

We are highly focused on maximizing the throughput of our facilities and optimizing our product mix to increase the

profitability per machine hour. We believe there are significant opportunities to do so through rigorous focus on the products

we choose to make, investments in asset integrity and reliability, and continuous improvements in our operations such as

debottlenecking and optimizing equipment uptime, speed and recovery. Finally, we complement these efforts by increasing

recycling to strengthen our margins, reduce our dependence on external slab and billet suppliers and expand our sustainable

product offerings.

(iv) Strictly Control Cost, Continuously Improve and Manage Resources Responsibly

We are committed to reducing our operating costs and improving our operations by implementing manufacturing

excellence, metal management and other cost improvement initiatives. These include standardizing manufacturing processes,

improving recovery and thereby reducing internal scrap generation, minimizing energy and water usage, maximizing external

scrap input and efficiently managing other resources used by the Company, including capital.

(v) Manage Capital Through a Disciplined Approach and Increase Financial Flexibility

We have invested capital in a number of attractive growth opportunities to advance our production capabilities, product

offerings and sustainability profile. We are highly focused on optimizing risk-return by being selective on growth projects and

realizing attractive returns on the capital we invest. In addition, we are highly focused on increasing our financial flexibility

through earnings growth and free cash flow conversion, which is critical to achieving our objectives of investing in our

operations and our people, maintaining a disciplined capital structure, whilst returning capital to our shareholders.

(vi) Commit to Our People and Communities

We believe our people are among the best, which is a competitive strength that allows us to be a leader in our industry.

We continuously provide training to our employees, invest in their skills and competencies, and promote a safe and inclusive

environment where everyone is valued, contributes, and thrives. We also strive to be socially responsible operators in our

communities.

Our Operating Segments

Our business is organized into three operating segments:

(i) Aerospace & Transportation Operating Segment

Our Aerospace & Transportation (“A&T”) operating segment offers a wide range of technically advanced aluminum

products including plate, sheet and extrusions to blue-chip customers in the global aerospace, space, defense, commercial

transportation and general industrial sectors. Many of our products are mission critical, benefiting from our world-class R&D

and manufacturing capabilities and unique solutions.

We are a global leader in the supply of advanced aluminum alloy plates, sheets and extrusions to the aerospace, space and

defense industries. The aerospace, space and defense industries require 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 have developed Airware®, a lightweight specialty aluminum-lithium alloy, for our aerospace, space and defense

customers to address increasing demand for lighter and more fuel-efficient commercial and military aircraft and spacecraft.

Additionally, aerospace, space and defense products are generally subject to long qualification periods. Our facilities have been

qualified by external certification organizations including the National Aerospace and Defense Contractors Accreditation

Program (“NADCAP”), and our products have been qualified by our customers. We are also a leading supplier to the land-

based defense, commercial transportation and general industrial end-markets in North America and Europe. Our product

portfolio in these segments includes both specialty aluminum plates and sheets, as well as standard products. Our A&T

customers are diverse and range across commercial and military aerospace, space, defense, commercial transportation, and

general industrial end-markets. The majority of our contracts with our largest aerospace customers are multi-year contracts,

which provide visibility on volumes and profitability. Our contracts in commercial transportation and defense are typically

between one to three years. Our contracts with general industrial customers tend to be one year or less.

(ii) Packaging & Automotive Rolled Products Operating Segment

Our Packaging & Automotive Rolled Products (“P&ARP”) operating segment includes the development and production

of customized rolled aluminum sheet products. We supply the packaging market with canstock and closure stock for the

beverage and food industry, as well as foilstock for the flexible packaging market. In addition, we supply the automotive market

with technically advanced products such as Auto Body Sheet (“ABS”), heat exchanger materials and battery foil products.

We are a leading supplier of canstock in North America and Europe and a leading supplier of closure stock globally. We

are also a major supplier of ABS in both North America and Europe, and heat exchanger materials and battery foil in Europe.

These products are subject to the exacting requirements and qualification processes of our customers which we believe provide

our technically advanced products with a competitive advantage. We are also a key player in the recycling of aluminum scrap,

including used beverage cans in North America and Europe. We have a diverse customer base, consisting of many of the

world’s largest beverage companies, can makers, food and specialty packaging producers, automotive original equipment

manufacturers (“OEMs”) and general industrial companies. Our contracts in packaging and automotive are typically multi-year.

(iii) Automotive Structures & Industry Operating Segment

Our Automotive Structures & Industry (“AS&I”) operating segment produces (i) technologically advanced structural

solutions for the automotive industry including crash management systems, body structures, side impact beams and battery

enclosure components, (ii) soft and hard alloy extrusions for automotive, transportation, and general industrial applications, and

(iii) large profiles for rail and general industrial applications. We complement our products with a comprehensive offering of

downstream technology and services, which include pre-machining, surface treatment, R&D and technical support services.

We are a key supplier of aluminum extruded products to automotive customers in North America and Europe. Due to the

unique combination of strength and weight, aluminum extruded structural solutions are increasingly favored by our automotive

customers given priorities on safety, lightweighting and sustainability. By leveraging our unique R&D partnership with the

Brunel University in the United Kingdom, we have developed proprietary alloys and manufacturing technology which have

enabled us to deliver high-quality and cost-effective products to our automotive customers. We believe that we are one of the

largest providers of aluminum automotive crash management systems globally, and our customers include some of the largest

North American and European car manufacturers. Our automotive structures contracts are typically multi-year, which usually

represents the lifetime of a model. We also serve a broad range of customers across a number of industries outside of

automotive, including rail, other transportation and general industrial markets in Europe. The non-automotive businesses

typically have contracts which are shorter-term in nature.

Our Industry

Aluminum Sector Value Chain

Aluminum has a number of unique physical characteristics. It is infinitely recyclable and recycling aluminum requires

only approximately 5% of the energy required to produce primary aluminum. Aluminum’s corrosion resistance and its

malleability also allow it to be easily cast, shaped, machined and used across a variety of applications. In addition, aluminum is

lightweight, with one-third the density of steel but offering similar stiffness, which results in products offering strength and

stability, particularly when alloyed with other metals. All of these capabilities make aluminum a viable and versatile solution

for a growing number of manufacturing and consumption needs.

The global aluminum industry consists of (i) mining companies that extract bauxite, the ore from which aluminum is

derived, (ii) primary aluminum producers that refine bauxite into alumina and smelt alumina into aluminum, (iii) aluminum

semi-fabricated products manufacturers, including aluminum casters, extruders and rollers, (iv) aluminum recyclers and

remelters, and (v) integrated companies that are present across multiple stages of the aluminum production chain.

Constellium’s Position in the Aluminum Sector Value Chain

Aluminum value chain

Our business is primarily focused on adding value through rolling and extruding aluminum into semi-fabricated and in

some instances fully-fabricated alloyed aluminum products, for a variety of end-markets. We recycle aluminum, both for our

own use and as a service to our customers. We do not participate in upstream activities such as mining, refining bauxite or

smelting alumina into aluminum. The aluminum rolled products industry is characterized by economies of scale, as significant

capital investments are required to achieve and maintain technological capabilities and to meet demanding customer

qualification standards. The aluminum extruded products industry also requires significant capital investments in order to

achieve and maintain technological capabilities and to meet demanding customer qualification standards but is comparatively

more fragmented and generally more local and regional. The supply of aluminum rolled and extruded products has historically

been affected by production capacity, alternative technology substitution and trade flows between regions. The demand for

these products has historically been affected by economic growth, substitution trends, cyclicality and seasonality, among other

factors.

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

•Slabs or billets we cast from a combination of primary and recycled aluminum. The primary aluminum is typically

in the form of standard ingots. The recycled aluminum comes either from scrap from fabrication processes or from

recycled end products in their end-of-life phase, such as used beverage cans.

•Slabs or billets purchased from smelters or metal trading companies.

The cost of primary aluminum is based on the London Metal Exchange (“LME”) quoted price plus a regional premium.

Recycled aluminum is also tied to LME pricing (typically sold at a discount to LME price and regional premium). The rolled

and extruded aluminum product prices for our products are based generally on the cost of primary aluminum plus a conversion

margin (i.e., the margin to convert the aluminum into a semi-finished product). As a result, the price of primary aluminum is not

a significant driver of our conversion margin because we typically pass through the metal cost either to our customers and / or

the financial market. Instead, the long-term financial performance of producers of rolled and extruded aluminum 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.

Overview of Aluminum Rolled Products, Extrusions and Automotive Structures

Our aluminum rolling process consists of passing alloyed aluminum slabs through a hot-rolling mill and then transferring

it to a cold-rolling mill, which gradually reduces the thickness of the metal down to approximately 6 mm for plates and to

approximately 0.2-6 mm for sheet. Aluminum rolled products, including sheet, plate and foil, are semi-fabricated products

which are used by our customers for their manufacturing of finished goods ranging from packaging, such as beverage cans, to

transportation applications, such as automotive body panels, fuselage sheet and aircraft wing parts. According to CRU

International Limited (“CRU”), the compound annual growth rate (“CAGR”) for aluminum rolled products between 2025 and

2030 is expected to be 3.6%.

Aluminum extrusion is a technique used to transform alloyed aluminum billets into semi-fabricated products with a

defined cross-sectional profile for a wide range of uses. In the extrusion process, a heated aluminum billet is forced through a

die and the extruded products can be manufactured in many sizes and in almost any shape. Today, aluminum extrusions are

used for a wide range of purposes, including building, general industrial and transportation where virtually every type of vehicle

contains aluminum extrusions, including planes, boats, bicycles, trains and cars. In our automotive structures business,

automotive extruded profiles are further machined and processed into a system of fully-fabricated automotive structural

components. Aluminum extruded products are favored by our automotive customers due to their unique combination of

strength and weight.

Our Key End-markets

Aerospace

Demand for aerospace plate and sheet is primarily driven by the build rate of commercial aircraft, which we believe will

be supported for the foreseeable future by (i) the increasing demand for air travel in an environment of general economic

growth, (ii) the increased affordability and accessibility of air travel to people from diverse socio-economic backgrounds, (iii)

the expansion of airline networks and the opening of new routes to previously underserved destinations and (iv) the necessary

replacement of aging fleets by airline operators, particularly in the United States and Western Europe by more fuel-efficient

aircraft. Over the longer term, the fundamentals driving aerospace demand growth remain intact. Between 2024 and 2044,

Airbus predicts over 42,000 new aircraft across all categories of large commercial aircraft with 35% of sales of new airplanes to

Europe and North America, 46% of sales of new airplanes to Asia Pacific and the remaining 19% to the Middle East, Latin

America and Africa. According to CRU, demand for the aerospace aluminum rolled products markets in North America and

Europe is expected to grow by 8.5% per annum from 2025 to 2030.

Packaging

The packaging industry has historically been relatively resilient during periods of economic downturn and has had

relatively limited exposure to economic cycles and periods of financial instability. Aluminum is a preferred material for

beverage packaging as it allows drinks to chill faster, can be stacked for transportation and stored more densely than competing

formats (such as glass bottles), is highly formable for unique or differentiated branding, and offers significant environmental

advantage of convenient, cost- and energy-efficient recycling. As a result of these benefits, aluminum is increasingly the

beverage packaging container of choice and is displacing tinplate, glass and plastics as the preferred packaging material

including in the growing specialty product categories. According to CRU, demand for the aluminum canstock market in North

America and Europe is expected to grow by 2.8% and 3.5% per annum between 2025 and 2030, respectively.

Automotive

We believe that the main drivers of automotive sales include overall economic growth, credit availability, level of

financing rates, vehicle prices and consumer confidence. Within the automotive sector, the demand for aluminum rolled and

extruded products may increase faster than the underlying demand for light vehicles due to aluminum’s high strength-to-weight

ratio in comparison to steel and a need for increased energy efficiency. In general, governmental regulations relating to

reductions in carbon emissions and focus on fuel-efficiency trends correlate to the increased use of aluminum to “lightweight”

traditional vehicles in order to facilitate better fuel economy, improve emissions performance and enhance vehicle safety. In

addition, increased electric vehicle penetration should drive increased demand for aluminum rolled and extruded products due

to the greater importance of lightweighting to maximize range, better thermal conductivity for battery boxes and superior

energy absorption, as compared to steel. Our automotive rolled, extruded and structural products are predominantly used in

premium models, light trucks and sport utility vehicles manufactured by North American and European OEMs. According to

industry research, light vehicle production is expected to grow in North America and Europe by approximately 1.7% and 1.5%

per annum from 2025 to 2030, respectively. Comparatively, CRU estimates that the consumption of ABS in North America and

Europe is expected to grow by 1.7% and 8.2% per annum between 2025 and 2030, respectively.

Our Business Operations

Our business model is to add value by converting aluminum into semi-fabricated and in some instances fully-fabricated

products.

Managing Our Metal Price Exposure

It is our policy not to speculate on metal price movements.

For all contracts, we seek to minimize the impact of fluctuation in the LME price and regional and other premiums for

aluminum that we buy and sell in order to protect our cash flows, with the following methods:

•In cases where we are able to align the price and quantity of physical aluminum purchases with that of physical

aluminum sales to our customers, we enter into back-to-back arrangements with our customers.

•When we are unable to align the price and quantity of physical aluminum purchases with that of physical aluminum

sales to our customers, we enter into derivative financial instruments to pass through the exposure to financial

institutions.

•For a small portion of our volumes, the aluminum that we process is owned by our customers and we bear no

aluminum price risk.

Sales and Marketing

Our sales force is based in the U.S., Europe (France, Germany, Czech Republic, United Kingdom and Switzerland) and

Asia (China, Japan and South Korea). We primarily serve our customers directly and in some cases through distributors.

Raw Materials and Supplies

A majority of our rolling slab and extrusion billet needs is produced internally at our casthouses. The remaining external

rolling slab and extrusion billet needs are secured through long-term contracts with several upstream suppliers. All of our top 10

metal suppliers (covering rolling slabs, extrusion billets, primary, high purity, scrap and hardeners) have been long-standing

suppliers to our plants, in many cases, for more than 10 years. In aggregate, the top 10 suppliers accounted for approximately

49% of our total metal purchases (in terms of volumes) for the year ended December 31, 2025. We typically enter into annual

or multi-year contracts with 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, to supplement the

capacity of our own internal casthouses.

•Production scrap from customers and scrap traders.

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

•Alloying elements and primary ingots from producers and metal traders.

Our operations use energy in the forms of natural gas and electricity, which represents one of the largest components of

our operating costs, after metal costs, labor costs and depreciation. We purchase energy from the natural gas and electricity

markets and typically secure a large part of our needs pursuant to fixed-price commitments. To reduce the risks associated with

our natural gas and electricity requirements, we primarily use forward contracts with our energy suppliers, and to a lesser

extent, derivative financial instruments with financial institutions, to fix the commodity component of the energy costs.

Furthermore, in some of our longer-term sales contracts, we include indexation clauses on energy prices. From time to time, we

may experience fluctuations in energy costs in the periods of higher volatility.

Our Customers

Our customer base includes some of the leading manufacturers in the aerospace, space, defense, packaging and

automotive end-markets. We have a relatively diverse customer base with our 10 largest customers representing approximately

56% of our revenue for the year ended December 31, 2025. We generally have long-term relationships with our large

customers, many of which span decades.

We see our relationships with our customers as partnerships. In each of our end-markets, we closely collaborate with our

customers to complete a rigorous product qualification process, which requires substantial time and investment and creates high

switching costs. In addition, our product portfolio is predominantly focused on high value-added products, which tend to

require close collaboration with our customers to develop technically advanced and tailored solutions to meet their evolving

requirements. The significant effort and investment to adhere to rigorous qualification procedures, the close collaborations on

technical development and customized offerings, and the focus on product quality and service reliability enable us to foster

long-term and mutually beneficial relationships with our customers.

Competition

The worldwide aluminum rolled and extruded industry is highly competitive. 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. Aluminum competes with other materials such as steel, glass, plastics and composite materials for various

applications. We compete with a variety of both U.S. and non-U.S. companies in all major markets across the aluminum supply

chain.

Seasonality

Customer demand in the aluminum industry is seasonal 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 from January to

July. 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 and the automotive and aerospace sectors encounter slowdowns in

both the third and fourth quarters of the calendar year.

Research and Development

We have three R&D centers located in Voreppe, France, Plymouth, Michigan and Brunel University, London, United

Kingdom. We engage in R&D to develop new products, improve our processes, and support the objectives of our customers.

We invested $51 million, $49 million and $52 million in R&D in the years ended December 31, 2025, 2024 and 2023,

respectively.

C-TEC, our world-class R&D center located in Voreppe, primarily serves our A&T and P&ARP operating segments and

specializes in product and process development, product testing and technical assistance to our plants and customers. Our R&D

centers in Plymouth and in Brunel provide support to our North American and European automotive customers in the AS&I and

P&ARP operating segments by addressing specific market requirements related to our aluminum-based automotive

lightweighting solutions.

Intellectual Property

We actively manage intellectual property arising from our operations and our R&D activities and, when appropriate,

apply for patents in the appropriate jurisdictions. We currently hold more than 270 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 our business. In connection with our collaborations with universities

and other third parties, we occasionally obtain royalty-bearing licenses for the use of third-party technologies in the ordinary

course of business.

Insurance

We have implemented a corporate-wide insurance program consisting of both master policies with worldwide coverage

and local policies to complement our global coverage and/or where required by applicable regulations. Our insurance coverage

includes: (i) property damage and business interruption; (ii) general liability including operational, professional, product and

environment liability; (iii) aviation product liability; (iv) marine cargo (transport); (v) business travel and personal accident; (vi)

construction all risk; (vii) automobile liability; (viii) trade credit; (ix) cyber risk; (x) workers’ compensation in the U.S.; and (xi)

other specific coverages for executive and special risks. We believe that our insurance coverage terms and conditions are

customary for a business such as Constellium. 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 international, national, 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 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 ("EHS") laws and regulations. Environmental compliance at our key facilities is supervised by the relevant local agencies

in the jurisdictions where we operate. Violations of EHS laws and regulations, and remediation obligations arising under such

laws and regulations, may result in restrictions being imposed on our operating activities as well as fines, penalties, damages or

other costs. Accordingly, we have implemented EHS policies and procedures to protect the environment and monitor

compliance with these laws and regulations, and we incorporate EHS considerations into our planning for new projects. We

perform regular risk assessments and EHS reviews. We closely and systematically monitor and manage situations of

noncompliance with EHS laws and regulations and cooperate with authorities to address any noncompliance issues. New

regulations, if and when promulgated, or unforeseen events, may result in increases in the number of our non-compliant

situations which may have a material adverse effect on our financial condition, results of operations or liquidity.

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 remediation costs

provisions at December 31, 2025 were $98 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 our general capital expenditure plan, we expect to incur capital expenditures for other capital projects that, in addition to

improving operations, also reduce certain environmental impacts such as energy consumption, air emissions, water releases,

and waste streams optimization. Capital expenditures for existing facilities were approximately $26 million in 2025.

Human Capital

As of December 31, 2025, we employed approximately 11,500 employees. In addition, we contracted with approximately

500 temporary workers. Approximately 90% of our employees were engaged in production and maintenance activities and

approximately 10% were employed in support functions. Approximately 26% of our employees were employed in the United

States, 35% in France, 20% in Germany, 5% in Switzerland, and 14% in Eastern Europe and other regions. Approximately 50%

of U.S. employees and a majority of non-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. In the U.S., in 2025, collective bargaining

agreements were negotiated and extended at our facilities in Ravenswood and Muscle Shoals.

We are committed to creating a great place to work where all employees can thrive and have equal access and

opportunity to develop. In living our company values, our people strategy reflects the importance of safety being our first and

foremost concern followed by trust, transparency, respect, empowerment, and collaboration. We actively recruit high-potential

candidates, engage our employees through ongoing communication, provide access to learning and leadership programs, and

value the broad-reaching abilities and skills our employees possess. As a global organization, we empower our teams to make

decisions and implement policies aligned with local practices and law. While we have a global philosophy that influences many

aspects of human rights and employment, it is not intended to replace or interfere with local dialogue, regulations and

negotiation practices. We regularly evaluate and assess our human rights practices and potential risk through a Human Rights

Impact Assessment at least every five years.

Labor Practices and Policies

Safety. Safety is our utmost priority. Our industry requires material, equipment, and processes that may pose risks to the

health and safety of our employees, contractors, and visitors. Accordingly, we have defined and implemented strict policies and

processes to protect everyone in our facilities. The goal is to achieve zero injuries and illnesses by integrating safety into all

aspects of our business.

Health. Over the last several years we have implemented various programs and policies across the organization to bring

awareness to health and wellness. We routinely assess the Company’s paid leave, vacation, and other policies and practices to

help provide employees with greater access to resources to help support a healthy lifestyle.

Labor Union Affiliations. Employees have the right to organize and bargain collectively with Constellium and engage in

other protected activities. We work in connection with the relevant works councils and unions to negotiate outcomes that

benefit employees and the business in alignment with local legal frameworks. We encourage open dialogue and enter into these

discussions with trust, respect and collaboration in mind.

Recruiting, Training, Development & Retention

Recruiting. Constellium is committed to attracting, developing, and retaining top talent. We actively recruit individuals

with diverse backgrounds and experiences who share our passion for shaping a sustainable future through advanced aluminum

solutions. Our recruitment strategy emphasizes promoting a culture of inclusion, continuous learning and career advancement

Item 1A. Risk Factors

You should carefully consider the risks and uncertainties described below and the other information in this Annual

Report. It is not possible to predict or identify all the risks and uncertainties to the Company’s business and the following is not

meant to be a complete discussion of all such potential risks or uncertainties. If known or unknown risks or uncertainties

materialize, the Company’s business, financial condition or results of operations could be adversely affected, potentially in a

material way, which in turn can affect the price of the Company’s publicly traded securities.

BUSINESS AND OPERATIONAL RISKS

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 market share, sales volumes and selling prices.

We are engaged in a highly competitive industry and compete in the production and sale of aluminum rolled and

extruded products with a number of other producers, some of which are larger and have greater financial and technical

resources than we do. As a result, these competitors may have an advantage over us in their abilities to research and develop

technology, pursue acquisitions, investments and other business opportunities, market and sell their products and services,

capitalize on market opportunities, enter new markets, and withstand business interruptions, pricing reductions, or adverse

industry or economic conditions. In addition, producers with a lower cost basis may, in certain circumstances, have a

competitive advantage. Further, an existing or new competitor may add or build new capacity, which could increase

competitive pressure in our markets. New competitors could emerge within aluminum, steel, or other materials that may seek to

compete in our industry. Emerging or transitioning markets in 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. Moreover,

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 market share, sales volumes and financial position, results of operations and

cash flows may be negatively impacted.

Aluminum may become less competitive with alternative materials, which could reduce our sales volumes, or

lower our selling prices.

Our offerings compete with products made from other materials, such as steel, glass, plastics, and composite materials,

for various applications. Higher aluminum prices relative to alternative materials may make aluminum products less

competitive. Environmental and other regulations may also make our products less competitive as compared to materials that

are subject to less onerous regulations. Customers in our end-markets use and continue to evaluate the further use of alternative

materials to aluminum in order to reduce the weight and increase the efficiency of their products. The willingness of customers

to accept substitutions for aluminum could materially adversely affect our financial position, results of operations and cash

flows.

A significant portion of our revenue is derived from international operations, which exposes us to certain risks

inherent in doing business globally.

We are a global company with operations in the United States, France, Germany, Switzerland, the Czech Republic,

Slovakia, China, Spain, Canada, and Mexico, and we sell our products primarily across North America, Europe, and Asia.

Economic downturns in regional and global economies, or a prolonged recession in our principal industry segments, have had a

negative impact on our operations in the past by reducing overall demand for our products, and could in the future have a

negative impact on our financial condition or results of operations.

We are generally subject to financial, economic, regulatory and business risks in connection with our global operations,

including risks relating to:

•uncertain social, political, regulatory, or trade conditions and instability (e.g., duties, taxes, tariffs, sanctions,

embargoes and trade negotiations);

•changes in regulations and laws of multiple jurisdictions, including those relating to taxes, employment,

repatriation of earnings and foreign trade restrictions;

•compliance with sanction regimes and export control laws of multiple jurisdictions;

•currency restrictions, currency exchange rate and interest rate fluctuations;

•the potential for nationalization of enterprises or government policies favoring local production;

•renegotiation or nullification of existing agreements;

•high rates of excessive, sustained or prolonged inflation;

•differing protections for intellectual property and their enforcement;

•divergent environmental laws and regulations;

•significant supply/demand imbalances impacting our industry;

•public health crises, epidemics and pandemics; and

•sustained economic downturns, volatility, and instability, regionally and globally.

The occurrence of any of these events could cause our costs to rise, limit growth opportunities, have a negative effect on

our operations and financial results, as well as on our ability to plan for future periods. Similarly, if any of our customers or

suppliers are similarly impacted, we could be indirectly impacted, and our operations and financial results could be adversely

affected. The duration, intensity and consequences of such impacts are uncertain and unpredictable, and we may not be able to

adequately foresee or mitigate events that could disrupt and have a negative impact on our operations.

Geopolitical instability could adversely affect our business.

Geopolitical instability, including inter-governmental tensions, conflicts, wars, terrorist acts and tensions between nation

states can affect the normal and peaceful course of international relations and can have an adverse impact on regional and

global economic conditions and our financial condition. Disruptive geopolitical developments, such as the conflict between

Russia and Ukraine, and other events beyond our control can increase economic volatility globally. Such instability and

volatility in or around any of the countries in which we do significant business may result in changing regulatory requirements,

market dislocations, supply chain disruptions and other disruptive consequences, any of which could impact our business,

results of operations, financial condition, cash flows, operating strategy, and profitability.

Shifts in international trade policies, imposition or increase of tariffs, or other restrictive trade measures could

adversely affect our business, results of operations, financial position and cash flows.

Shifts in international trade policies could adversely affect our business, results of operations, financial position and cash

flows. Governmental actions such as tariffs, revisions to trade agreements, and other alterations to trade relationships could

necessitate substantial changes to our business practices and could impact our business and financial results. Rapid shifts in

trade policy and introduction of other restrictive trade measures create uncertainty in our operations and business outlook.

Throughout 2025, the U.S. initiated a number of measures with respect to reevaluating and revising certain trade policies, some

of which have impacted our business. These included imposition of new import tariffs and quotas, revision of international

trade policy, renegotiation of certain trade agreements, and other changes that have affected U.S. trade relations with other

countries.

Significant uncertainty exists about the future international trade environment and resulting trade policies, treaties and

tariffs. Future developments could have a substantial adverse effect on our supply chain and the overall aluminum industry, if

sustained for an extended period of time. The ultimate impact of such developments is uncertain and will depend on various

factors, including actual implementation, the timing and duration of their implementation, and the amount, scope, and nature of

any new or increased tariffs (or any elimination or reduction of tariff exemptions which are currently available to us), along

with numerous secondary and tertiary effects.

While we continue to take steps to mitigate potentially unfavorable impacts of the current trade environment, there is no

assurance that we will be successful in doing so in the evolving landscape. We intend to continue to assess the full implications

of tariffs and other trade barriers on the global aluminum market and their likely impact on our business. Changes in tariff law

and policy might require us to reconsider or seek to renegotiate our commercial agreements with suppliers and customers,

increase the prices of our products or alter the markets into which we procure our supplies or sell our products. Any or all of

these actions could adversely affect our business, financial condition, results of operations and cash flows.

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

Our operations use natural gas and electricity, which represent a large component of our cost of sales, after metal, labor

costs, and depreciation. We typically purchase the majority of our natural gas and electricity requirements on a forward basis

under fixed price commitments and long-term physical supply contracts with suppliers, which provide increased visibility on

costs. However, the volatility in costs of fuel, principally natural gas, and other utility services used by our manufacturing

facilities affects our operating costs. Fuel and utility prices are affected by factors outside our control, such as supply and

demand in both local and regional markets, as well as governmental regulation (including evolving climate change regulation),

imposition of taxes on energy and costs associated with CO2 emissions. We are a significant purchaser of energy and existing

and future regulations relating to the emissions by our energy suppliers could result in materially increased energy costs for our

operations which we may be unable to pass through to our customers. Although we have secured a large part of our near-term

natural gas and electricity supply under fixed price commitments and annual or multi-year physical supply contracts with

suppliers, future increases in fuel and utility prices, prolonged periods of excessive inflation, and/or disruptions in energy

supply, as we have experienced, may have an adverse effect on our financial condition, results of operations and cash flows.

If we are unable to substantially pass through to our customers the cost of price increases of our raw materials,

which may be subject to volatility, 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. The

overall price of primary aluminum consists of several components: (i) the underlying base metal component, which is typically

based on quoted prices from the LME; (ii) 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 United States or the Rotterdam premium for metal sold in Europe); and (iii) 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,

including the global aluminum supply and demand. Regional premiums tend to vary based on the supply and demand for metal

in a particular region, changes in tariffs 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 aluminum shape and alloy

combination in a particular region. Raw materials used in our products include alloying elements, such as copper, lithium,

magnesium, manganese, silicon, silver or zinc. Prices for these alloying elements are subject to constant volatility and may

increase significantly from time to time.

The inability to pass through any fluctuation in regional premiums, product premiums or other raw material costs to our

customers or the inability to meaningfully hedge our exposure to such prices could have a material adverse effect on our

business, financial condition, and results of operations and cash flows. In addition, although our sales are generally made on a

"margin over metal (aluminum) price" basis, if aluminum prices or those of the alloying elements we purchase increase, we

may not be able to pass on the entire increase to our customers. There could also be a time lag between when changes in metal

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 may be exposed to the effects of fluctuations in raw material prices, including

aluminum, due to this time lag. In some of our contracts we may have ineffective pass-through mechanisms related to regional

premium fluctuation, fluctuations in raw material cost, such as alloying elements, and fluctuation in tariffs or other costs. We

attempt to mitigate these risks through hedging and by improving the pass-through mechanisms, but we may not be able to

successfully reduce or eliminate all of the resulting impact, including higher operating costs, which could have a material

adverse effect on our financial results and cash flows.

The cyclical and seasonal nature of the metals industry, our end-use markets and our customers’ industries could

adversely affect our financial condition and results of operations.

Our end-markets are cyclical and tend to directly correlate with changes in general and local economic conditions. These

conditions include the level of economic growth, affordable energy sources, employment levels, the availability of financing,

interest rates and consumer confidence. We are particularly sensitive to cyclicality in the aerospace, automotive, defense,

industrial and transportation end-markets. During recessions or periods of low growth, these industries typically experience

major cutbacks in production, resulting in decreased demand for aluminum 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. Customer demand is also affected by holiday seasons, seasonal

slowdowns, weather conditions, economic downturns, and other factors beyond our control. In addition, customer demand can

be negatively affected during periods of destocking when inventory levels in the supply chain are higher than normal and our

customers and other participants in the supply chain consume their inventory in order to reduce inventory levels. Accordingly,

cyclical fluctuations and seasonality, reduced demand and pricing pressures may significantly reduce our profitability and

materially adversely affect our financial condition, results of operations and cash flows.

We may be unable to execute and timely complete our expected capital investments or may be unable to achieve

the anticipated benefits of such investments.

Our operations are capital intensive. We may not generate sufficient operating cash flows and our external financing

sources may not be available in sufficient amounts to enable us to make anticipated capital expenditures, or to complete them

on a timely basis. If we are unable to, or determined not to, complete our expected investments, or such investments are

delayed, we will not realize the anticipated benefits of such investments. In addition, if we are unable to make investments, or if

we delay investments for upgrades and repairs, 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, operational disruptions, reduced production capacity, and other competitive factors. Customer demand

for our products produced on new investments may be slow to materialize, and new equipment may not perform to our

expectations. These factors could adversely affect our results of operations.

We may fail to implement or execute our business strategy, successfully develop, and implement new technology

initiatives and other strategic investments.

Our future financial performance and success depend in large part on our ability to successfully execute 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, containing our costs, and

executing on our manufacturing productivity improvement programs. Any inability to execute our strategy or delay in its

execution could reduce our expected earnings and could adversely affect our operations overall.

In addition, being at the forefront of technological development is important to remain competitive. We have invested in

and are involved with several technology and process initiatives. Several technical aspects of certain of these initiatives are still

unproven and 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 their impact on our financial results may vary from present expectations. Further, we have undertaken and may continue to

undertake strategic growth, streamlining and productivity initiatives and investments to improve performance. We cannot be

certain 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 expect at the time of committing to the

investment.

We may be affected by climate change or by legal, regulatory, or market responses to such change, and our efforts

to meet sustainability targets or standards or to enhance the sustainability of our businesses may not meet the

expectations of our stakeholders or regulators.

From time to time, our business has been and may continue to be impacted by physical risks associated with climate

change such as severe weather conditions, which can cause floods and other natural disasters and result in outages, supply or

logistics delays, disruptions and shortages (such as prolonged periods of drought which may result in restrictions on water use),

as well as damage to our plants, machinery and equipment and the risk of physical harm to our personnel and others. For

example, our Valais facilities experienced flooding at the end of June 2024 as a result of severe flooding from the Rhône River.

The severity and frequency of natural disasters and severe weather conditions can adversely impact our operations and financial

condition and may be further exacerbated by climate change.

Climate change is a focus of many governments and has led to new laws and regulations and further proposed legislative

and regulatory initiatives in many of the countries in which we, our suppliers and customers operate. Such legal and regulatory

initiatives are subject to changes, as governmental policies relating to such issues evolve. As changes are implemented, existing

and new or revised laws and regulations in this area could directly and indirectly affect us, our customers, and suppliers,

including by increasing the costs of production or impacting demand for and the price of certain products. Changes in law or

government policy may also have the effect of changing the expected timing of projects or initiatives.

Compliance with any new laws or regulations or differing interpretations of existing laws could also require additional

capital and other expenditures by us, our customers or suppliers. We are also subject to environmental reviews, investigations,

and remediation by relevant governmental authorities from time to time. Any increase in the direct or indirect costs in response

to new laws and regulatory requirements could be passed through to us, our customers, and suppliers, which could also have a

negative impact on our financial condition and profitability.

We make statements about our sustainability goals and initiatives through information provided in reports that we file or

furnish with the Securities and Exchange Commission, on our website, in press statements, and in other communications,

including through our Sustainability Reports. Our response to these sustainability considerations and the implementation of

these goals and initiatives involves risks and uncertainties, including those described under “Forward-Looking Statements,” and

such response, as well as our ability to achieve such goals, may be impacted by factors that are outside our control.

In addition, some of our shareholders, investors, customers, or those considering such a relationship with us, may

evaluate our business or other practices according to a variety of sustainability targets, standards and expectations. Further, we

define our own corporate purpose, in part, by the sustainability of our practices and our impact on all our stakeholders. As a

result, our efforts to conduct our business in accordance with some or all of these targets, standards and expectations (and

applicable laws and regulations) may involve trade-offs and may not satisfy all stakeholders. Some stakeholders may disagree

with our goals and initiatives and the focus of stakeholders may change and evolve over time. Stakeholders may also have

different views on the relative prioritization of the Company's sustainability focus, including differing views of regulators in

various jurisdictions in which we operate. Our policies and processes to evaluate and manage sustainability targets and

standards in coordination with other business priorities may not prove completely effective. Any failure, or perceived failure, by

us to achieve our goals, further our initiatives, adhere to our public statements, comply with local or international

environmental, social and governance laws and regulations, or meet evolving and varied stakeholder expectations and standards

could prompt public, investor, regulatory scrutiny, or result in legal and regulatory proceedings against us, any of which could

materially adversely affect our business, reputation, results of operations, financial condition and stock price.

Our failure to meet customer manufacturing and quality requirements, standards, and demand, or changing

market conditions could have a material adverse impact on our business, reputation, and financial results.

Product manufacturing in our business is a highly complex process. Our customers specify quality, performance, and

reliability standards that we must meet. If our products do not meet these standards or are defective, we may be required to

replace or rework the products. We have experienced product quality, performance or reliability problems and defects from

time to time and similar defects or failures may occur in the future.

Some additional factors that could adversely impact our ability to meet our customer requirements and demand, or

changing market conditions include:

•making substantial capital investments sufficient to repair, maintain, upgrade, and expand our facilities and

equipment. Notwithstanding our ongoing plans and investments to increase our capacity, we may not be able to

maintain our production capacity or expand it quickly enough to meet our customer requirements;

•unplanned business interruptions caused by events such as explosions, fires, inclement weather, floods and other

natural disasters, pandemics or other public health crises, economic and political instability and unrest, wars,

accidents, equipment failure and breakdown, IT systems and process failures, electrical blackouts or outages,

transportation, and global and regional supply interruptions. Any such event or incident at or in proximity to one or

more of our manufacturing facilities or which otherwise affects our business and operations could cause substantial

losses or delays in our production capacity, increase our operating costs, and have a negative financial impact on

the Company and our customers. Business and operational interruptions may also harm our reputation among

actual and potential customers, and the reputation of our customers;

•qualification of our products by our customers can be lengthy and unpredictable as many of these customers have

extensive sourcing and qualification processes, which require substantial time and financial resources, with no

certainty of success or recovery of our related expenses and investments. Failure to qualify or re-qualify our sites

and products may result in us losing such customers or customer contracts; and

•implementing manufacturing processes in new locations, or for new equipment or newly introduced products, may

present difficulties, including operational and manufacturing disruptions, delays, or other complications, which

could adversely affect our ability to timely launch or ramp-up productions and serve our customers.

If these or any other similar manufacturing or quality failures occur, they could result in losses or product recalls,

customer penalties, contract cancellation and product liability exposure. Further, they could adversely affect product demand,

result in negative publicity, damage our reputation, and could lead to loss of customer confidence in our products, which could

have a material adverse impact on our business, financial position, and results of operations.

We are dependent on a limited number of customers for a substantial portion of our sales and a failure to

successfully renew or renegotiate our agreements with such customers may adversely affect our results of operations,

financial condition, and cash flows.

Our business is exposed to customer concentration risk. A significant downturn in the business, credit or financial

condition of our largest customers could expose us to the risk of default on contractual agreements, or reductions or deferrals of

those customers' requirements for our products.

Our customer contracts and related arrangements are subject to renewal, renegotiation, or re-pricing at periodic intervals

or, in some cases, upon changes in competitive and regulatory supply conditions. Some of our customer contracts also provide

termination rights to our customers or may have provisions that may become less favorable to us over time. If we fail to

successfully renew or renegotiate customer contracts or arrangements, negotiate improved terms, or if we are not successful in

replacing business lost from such customers, then our results of operations, financial condition and cash flows could be

materially adversely affected. Similarly, any material deterioration in, or termination of, these customer relationships could

result in a reduction or loss in sales volume or revenue which could materially adversely affect our results of operations,

financial condition, and cash flows.

Relatedly, we have dedicated facilities serving certain of our customers which subjects us to the inherent risk of increased

dependence on such customers with respect to these facilities. In such cases, the loss of a customer, or the reduction of that

customer’s business at these facilities, or the deterioration of such customer’s credit or financial condition, could materially

adversely 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 ability of large customers to exert leverage in the market to reduce the pricing for our aluminum products could

materially adversely affect our financial position, results of operations and cash flows. In addition, customers in our end-

markets, including the packaging, automotive, and aerospace sectors, may consolidate and grow in a manner that could affect

their relationships with us. If our customers become larger and more concentrated, they could exert financial pressure on all

suppliers, including us. Accordingly, our ability to maintain or raise prices in the future may be limited, including during

periods of raw material and other cost increases. If we are forced to reduce or maintain prices or reduce volumes of production

during periods of increased costs, or if we lose customers because of consolidation, pricing or other methods of competition,

our financial position, results of operations and cash flows may be adversely affected. If as a result of consolidation in our

industry, our competitors are able to exert financial pressure on suppliers, obtain more favorable terms or otherwise take actions

that could increase their competitive strengths, our competitive position may be materially adversely affected.

We are dependent on a limited number of suppliers for a substantial portion of our aluminum supply and general

stability in the primary and scrap aluminum markets, and a failure to successfully renew or renegotiate our agreements

with our suppliers, supply interruptions, and/or adverse changes in the primary and scrap aluminum market dynamic,

may adversely affect our results of operations, financial condition, and cash flows.

Our ability to produce competitively priced aluminum products depends on our ability to procure competitively priced

aluminum in a timely manner and in sufficient quantities to meet our production needs. We have supply arrangements with a

limited number of suppliers for aluminum. Increasing aluminum demand levels and reduced availability have caused regional

supply constraints in the industry and further increases in demand and capacity limitations could exacerbate these issues,

particularly during periods of economic and political instability and conflict. We maintain annual and multi-year contracts for a

majority of our supply requirements and depend on spot purchases for the remainder of such requirements. There can be no

assurance that we will be able to renew or obtain replacements for such contracts. Additionally, if any of our key suppliers are

unable to deliver sufficient quantities on a timely basis, our production may be disrupted, and we could be forced to purchase

primary metal or other raw materials from alternative sources, which may not be available in sufficient quantities or may only

be available on terms that are less favorable to us and could also impact our overall sustainability targets. 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. Moreover, a

significant downturn in the business or financial condition of our significant suppliers exposes us to the risk of delays in supply

or default by the supplier on our contractual agreements.

We use a large amount of aluminum scrap for our operations and acquire our scrap inventory from numerous sources.

Our suppliers are generally not bound by long-term contracts and have no obligation to sell aluminum scrap to us. As an

example, a decrease in the supply of used beverage cans could negatively impact our supply of aluminum. In addition, when

using recycled material, we benefit from the difference between the price of primary aluminum and aluminum scrap.

Consequently, if this difference narrows and/or if the primary aluminum price were to decrease for a considerable period of

time or if an adequate supply of aluminum scrap is not available to us, we would be unable to recycle metals at desired volumes

and our results of operations, financial condition and cash flows could be materially adversely affected.

In addition, we use certain alloying elements for our operations, and the production of such alloying elements is highly

concentrated in certain countries. The suppliers of alloying elements are not bound by long-term contracts and have no

obligation to sell products to us. The availability and price exposure of alloying elements have experienced noticeable volatility

since late 2020, and this could continue in the future. Consequently, if prices increase for a considerable period of time or if an

adequate supply of alloying elements is not available to us, we would be unable to produce aluminum at desired volumes and

our results of operations, financial condition and cash flows could be materially adversely affected.

The loss of certain members of our senior management team or other key employees may have a material adverse

effect on our operating results.

Our success depends, in part, on the efforts of our senior management and other key employees. These individuals,

including our Chief Executive Officer and Chief Financial Officer, 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, or the cost of labor

significantly increases, 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 adversely affected. Moreover, the hiring of qualified individuals

is highly competitive in our industry, which may be impacted by labor shortages, 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. Further, the failure to

retain or provide adequate succession plans for key personnel could adversely affect our operations and competitiveness.

We could experience labor disputes and work stoppages, or be unable to renegotiate collective bargaining

agreements, which could disrupt our business and have a negative impact on our financial condition and results of

operations.

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. In addition, from time to time, we may experience labor disputes and work stoppages at our

facilities, which may or may not be in connection with collective bargaining agreement negotiations. Reasons for stoppages

include disapproval of governmental measures, solidarity with a dismissed employee, wage claims, protests against working

conditions and/or strikes. These disruptions can have a duration ranging from hours to weeks. Existing collective bargaining

agreements may not prevent a strike or work stoppage at our facilities. Any such stoppages or disturbances may adversely affect

our financial condition and results of operations by preventing or limiting plant production and adversely affecting sales

volumes, profitability, and operating costs.

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.

We have substantial pension and other post-employment benefit obligations. Most of our pension obligations relate to

defined benefit pension plans for our employees in the United States, Switzerland, France and Germany, and lump sum

indemnities payable to our employees in France and Germany upon retirement or termination. 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 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. Our pension plan assets consist primarily of funds invested in diversified portfolios. 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

shareholders’ equity 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.

FINANCIAL RISKS

Our level of indebtedness could limit cash flow available for our operations and capital expenditures and could

adversely affect our net income, our ability to service our debt or obtain additional financing, and our business

relationships.

We have a material amount of indebtedness, which we are required to manage. We believe that the cash provided by our

operations or future borrowings will be sufficient to provide for our cash requirements for the foreseeable future. However, our

ability to satisfy our obligations depends on our future operating performance and financial results, which are subject, in part, to

factors beyond our control, including interest rates and general economic, financial, and business conditions. We cannot be

certain 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.

In addition, our level of indebtedness could adversely affect our operations by:

•reducing the availability of our cash flow to fund working capital, capital expenditures, R&D efforts and other

general corporate purposes;

•adversely affecting the terms under which suppliers provide goods and services to us;

•limiting our flexibility in planning for, or reacting to, changes in our business and the markets in which we

compete, including limiting our ability to make strategic acquisitions; and

•placing us at a competitive disadvantage compared to our competitors that have less debt.

If we are unable to meet our debt service obligations and pay our expenses, we may be forced to reduce or delay business

activities and capital expenditures, 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.

A failure to comply with our debt covenants could result in an event of default. 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, plus accrued

and unpaid interest, and fees, to be due and payable, or take other remedial actions. Some of our indebtedness is also subject to

cross-default provisions, which means that if an event of default occurs under certain material indebtedness, such event of

default could trigger an event of default under other indebtedness. If our debt payments were to be accelerated, we cannot be

certain that our assets would be sufficient to repay such debt in full and our lenders could consequently foreclose on our

pledged assets.

In addition, a deterioration in our financial position or a downgrade of our credit ratings could adversely affect our

financing levels, 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. Such deterioration or downgrade of our credit ratings could also have an adverse effect on

our business relationships with customers, suppliers and hedging counterparties.

The agreements governing our debt, including the indentures governing our senior notes, contain, and may in

future financings contain, restrictive covenants that limit our ability to take certain actions, and failure to comply with

these covenants could have material adverse impacts on us.

Our financing arrangements contain restrictions, covenants and events of default that, among other things, impose

limitations on Constellium SE and/or certain of our subsidiaries incurring or guaranteeing additional indebtedness, paying

dividends or making other restricted payments, making investments, granting certain liens, entering into sale and lease-back

transactions, selling assets and subsidiary stock, and merging, consolidating or amalgamating with or into another entity.

Financing arrangements that we enter into in the future could contain similar restrictions and could additionally require us to

comply with similar, new or additional restrictions. Such restrictions could limit our ability to respond to market conditions,

provide for capital investment needs or take advantage of business opportunities by limiting the amount of additional

borrowings we may incur.

Various risks, uncertainties, and events beyond our control, including adverse macroeconomic conditions and reduced

customer demand, could affect our ability to comply with these restrictions and covenants. A failure to comply with our debt

covenants could result in an event of default. 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, plus accrued and unpaid interest, and fees, to be due

and payable, or take other remedial actions. Some of our indebtedness is also subject to cross-default provisions, which means

that if an event of default occurs under certain material indebtedness, such event of default could trigger an event of default

under other indebtedness. If our debt payments were to accelerate, we cannot be certain that our assets would be sufficient to

repay such debt in full and, in the case of our secured indebtedness, our lenders could consequently foreclose on our pledged

assets.

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 enter

into certain derivative instruments.

We enter into derivative financial instruments as part of our efforts to reduce our exposure to changes in currency

exchange rates, aluminum prices and other raw materials and energy prices. If we are unable to enter into such 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 program depends 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 us, our suppliers, or our

customers and other disruptions to our inventories. We may also be exposed to losses if the counterparties to our derivative

instruments fail to honor their agreements.

With the exception of hedges on certain long-term aerospace contracts, we do not apply hedge accounting to our

derivative financial instruments. Unrealized gains and losses on our derivative financial instruments that do not qualify for

hedge accounting are reported in our consolidated results of operations, or in the case of hedges relating to our indebtedness, in

Finance cost - net. 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, adverse market price

movements that reduce the fair value of our derivative positions may cause our mark‑to‑market requirements to exceed our

available credit lines, which could result in counterparties requiring us to post cash collateral.

At certain times, hedging instruments may simply be unavailable or not available on terms acceptable to us. In addition,

current legislation increases 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 foreign exchange and commodity positions, this could have an adverse

effect on our financial condition and results of operations.

Changes in income tax rates or 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 believe that we file our tax returns in compliance with the tax laws and

regulations of these jurisdictions. Various factors determine our effective tax rate and/or the amounts we are required to pay,

including changes in or interpretations of tax laws and regulations in any given jurisdiction or global and/or EU-based

initiatives, changes in geographical allocation of income and expense, the ability to use net operating loss and other tax

attributes, and the evaluation of deferred tax assets that requires significant judgment. Any resulting 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 tax authorities 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 and how the tax authorities and courts view

certain issues. Such amounts are included in income taxes payable or deferred income tax liabilities, as appropriate, and updated

over time. Any material adverse review could impact our financial position and results of operations.

LEGAL, GOVERNANCE AND COMPLIANCE RISKS

Significant legal proceedings and investigations, proprietary claims, regulatory and compliance costs, including

with regard to environmental matters, could increase our operating costs and adversely 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, product liability and warranty claims, intellectual property rights

or defending claims of infringement, employees, taxes, contracts, anti-competitive or anti-corruption practices as well as other

disputes and proceedings that arise in the ordinary course of our business. It could be costly to address these claims or any

related investigations, whether meritorious or not, and if found liable, we could be required to pay substantial monetary

damages. Legal proceedings and investigations could also divert management’s attention as well as operational resources,

adversely affecting our financial position, results of operations, cash flows, and reputation.

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 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. Further, we have a presence in China, which

historically has afforded less protection to intellectual property rights than the United States or Europe. 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 therefore may incur significant costs protecting such rights.

Our operations are subject to international, national, 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. As of December 31,

2025, we had environmental remediation costs provisions of $98 million. Future environmental regulations, requirements or

more aggressive enforcement of existing regulations could impose stricter compliance requirements on us and on the industries

in which we operate, such as legislative efforts to limit greenhouse gas emissions, including carbon dioxide. 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. In addition, changes to these laws and regulations could result in us being required to incur additional costs.

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

or be subject to claims for damages.

According to the Company’s articles of association (“Articles of Association”), any person, acting alone or in concert

within the meaning of Article L. 233-10 of the French Commercial Code, who comes into possession, other than following a

voluntary takeover offer, directly or indirectly, of more than 30% of the capital or voting rights of the Company, is required to

launch a takeover offer for all the shares and all securities granting access to the Company's shares or voting rights (i.e.,

securities providing for voting rights or convertible into, or exercisable for, shares), and on terms that comply with applicable

U.S. securities laws, and SEC and NYSE rules and regulations. The same requirement applies to persons, acting alone or in

concert, who directly or indirectly own a number between 30% and half of the total number of equity securities or voting rights

of the Company and who, in less than twelve consecutive months, increase the holding, in capital or voting rights, by at least

1% of the total number of equity securities or voting rights of the Company.

The rights of our shareholders may be different from the rights of shareholders of U.S. companies and 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 to our Board of

Directors.

Our corporate affairs are governed by the Company’s Articles of Association and by the laws governing companies

incorporated in France. The rights of shareholders and the responsibilities of members of our Board of Directors may be

different from the rights of shareholders and duties of directors in companies governed by the laws of U.S. jurisdictions. In the

performance of its duties, our Board of Directors is required by French law to consider the interests of the Company, its

shareholders, its employees, and other stakeholders, in all cases with due consideration to the principles of reasonableness and

fairness. It is possible that some of these stakeholders could have interests that are different from, or in addition to, our

shareholders’ interests.

Under French law shareholders generally do not have the right to bring a derivative action on behalf of a company or to

bring an action against a third party on their own behalf to recover indirect losses sustained by them as a result of the third

party’s breach of contractual or other obligations to the Company. Only in the event that the acts or omissions of the third party

also constitute a tort towards the shareholder, causing it direct, personal, and definite loss or damage, may the shareholder itself

have an individual right of action against such third party.

The French Consumer Code provides for the possibility to initiate class actions (actions en représentation conjointe);

however, such class actions are not available with respect to acts which affect the rights of shareholders. Approved associations

of shareholders or investors are allowed to bring claims in respect of wrongful acts harming the “collective interest” of the

investors or of certain categories of investors (or to exercise derivative action under certain conditions). Such associations may

request that the court orders responsible persons to comply with relevant legal requirements to end irregularities or eliminate

their effects. They may also seek indemnification in the name of individual investors who have suffered individual damages if

mandated by at least two such investors.

The provisions of French corporate law and the 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.

In addition, several provisions of the Articles of Association and the laws of France may discourage, delay or prevent a

potential investment, merger, consolidation or acquisition that shareholders may consider favorable, such as the obligation to

disclose the crossing of ownership thresholds. Under French law, our shareholders’ meeting may empower our Board of

Directors to issue shares, or warrants to subscribe new shares, and restrict or exclude preemptive rights on the issue of those

shares or warrants, including in the context of takeover offers. These provisions could 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 our

shareholders’ ability to realize any potential change of control premium. French law does not grant appraisal rights to a

company’s shareholders who wish to challenge the consideration to be paid upon a domestic legal merger or demerger of a

company. In addition, provisions of French law allowing the owner of 90% of the share capital and voting rights of a French

public company to force out the minority shareholders following a tender offer made to all shareholders are only applicable to

companies listed on a stock exchange of the EU and are therefore not applicable to us.

United States civil liabilities may not be enforceable against the Company.

We are incorporated as an SE under the laws of France and a majority of our directors and officers reside outside the

United States. It may be difficult for investors to effect service of process within the United States upon the Company or other

persons residing outside the United States. It may also be difficult to enforce outside of the United States judgments delivered

by U.S. courts in any action, including under the civil liability provisions of U.S. federal securities laws or to enforce rights

under U.S. federal securities laws in foreign courts.

There is no treaty between the United States and France 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

U.S. court based on civil liability would not be enforceable in France unless recognized by French courts in accordance with

French law. Moreover, a SEC decision ordering the payment of a fine would not be enforceable in France.

If a U.S. judgment is not recognized in France, the parties would have to re-litigate their dispute before a French court,

provided such court has jurisdiction over the dispute. Accordingly, there can be no assurance that U.S. investors will be able to

enforce any civil judgments obtained in U.S. courts, including under U.S. federal securities laws, against the Company or our

directors, our officers or certain experts who are residents of France or other foreign countries. In addition, there is doubt as to

whether a French court would impose civil liability on the Company, our directors, our officers or certain of our experts in an

action based on U.S. federal securities laws even if brought in a French court of competent jurisdiction.

Any inability of the Company to continue to benefit from French provisions applicable to registered

intermediaries (“intermédiaires inscrits”) could adversely affect the rights of shareholders.

Article 198 of the Pacte Act amended the French Commercial Code (article L. 228-1) in a way that allows us to maintain

our current shareholder ownership structure in the United States. The French Commercial Code (as amended by the Pacte Act)

allows an intermediary to be registered for the account of holders of shares of French companies which are admitted to trading

solely on a market in a non-EU country that is considered equivalent to a regulated market pursuant to paragraph (a) of Article

25(4) of Directive EC2014/65/EU (which, pursuant to the European Commission decision dated December 13, 2017, includes

the NYSE).

We use a French registered intermediary for the account of our beneficial owners (the “French Intermediary”). If the

French Intermediary fails to comply with the French provisions applicable to registered intermediaries (intermédiaires inscrits),

and if we are unable to find an appropriate substitute, or if the European Commission no longer considered the NYSE as

equivalent to an EU regulated market as described above, we might not be able to comply with existing French laws regarding

the holding of shares in the “au porteur” (bearer) form, and shares would have to be held in “au nominatif” (registered) form.

In such case, the Company would need to maintain at all times a register with the name of (and number of shares held by) each

shareholder, which could adversely affect the rights of our shareholders, including potentially the right to exercise their voting

rights as Company shareholders as only shareholders registered on such register would be entitled to vote.

If dividends were paid by our Company, it is uncertain whether our non-resident French shareholders would

actually obtain the elimination or reduction of the French domestic dividend withholding tax to which they would be

entitled.

In accordance with domestic or double tax treaty provisions, shareholders may be entitled to an elimination or reduction

of the default French withholding tax, on dividends distributed by the Company (i.e., 12.8%, 25%, or 75% in the case where the

dividends are paid in non-cooperative States or territories within the meaning of article 238-0 A 1, 2 and 2 bis-1° of the French

tax code), subject to the French paying agent of the dividends being provided with the required information and documentation

relating to the tax status of the shareholders. Numerous intermediaries would be involved in the process of transmitting the

relevant information and documentation from our shareholders to the French paying agent in case of the distribution of

dividends by the Company. As a result, this process may potentially jeopardize the ability for our non-resident French

shareholders to obtain the elimination or reduction of the French withholding tax to which they are entitled.

If dividends were paid by our Company, it is uncertain whether our shareholders would actually obtain the

elimination or reduction of the Dutch domestic dividend withholding tax to which they would be entitled.

Since the Company was initially incorporated under Dutch law it is deemed to be resident of the Netherlands for Dutch

dividend withholding tax purposes. Dividends paid on our ordinary shares since the transfer of domicile of our parent company

from the Netherlands to France are therefore, based on Dutch domestic law, still subject to Dutch dividend withholding tax at a

rate of 15%. Since our corporate seat has been transferred to France as of December 12, 2019, our dividends paid on our

ordinary shares generally should be subject to French dividend withholding tax and not to Dutch dividend withholding tax on

the basis of the double tax treaty between the Netherlands and France. However, both French and Dutch dividend withholding

tax may be required to be withheld from any such dividends paid, if and when paid to Dutch resident holders of our ordinary

shares and to non-Dutch resident holders of our ordinary shares that have a permanent establishment in the Netherlands to

which the ordinary shares are attributable. According to the Dutch tax authorities, Dutch dividend withholding tax must also be

withheld, in addition to the French withholding tax on dividends paid insofar as the identity of our shareholders cannot be

determined by the Company and therefore such shareholders would not be able to obtain elimination or reduction of the Dutch

domestic dividend withholding tax.

The French Ruling (as defined below) could be revoked if the description and legal analysis of the holding

structure of the shares of the Company after the completion of its transfer from the Netherlands to France was

inaccurate.

In connection with our transfer of domicile in 2019 from the Netherlands to France, the French tax authorities notably

confirmed by a ruling dated October 11, 2019 (the “French Ruling”) that the purchases of ordinary shares of the Company were

not subject to registration duties in France, subject to the absence of any deed concluded in France, and were not subject to the

French financial transaction tax. Such confirmation is based on the description and legal analysis of the holding structure of the

shares of the Company made by the Company to the French tax authorities in our request for its ruling. If the French tax

authorities were to consider that the description or legal analysis in the ruling request with regards to the holding structure of

the shares of the Company is inaccurate, notably to the extent that such description and analysis are based on U.S. securities law

notions that are foreign to French law, the French tax authorities could decide to revoke the French Ruling and such decision

could have adverse tax consequences for our shareholders.

Purchases of our ordinary shares could be subject to the French financial transaction tax if the NYSE were to be

formally recognized as a foreign regulated market by the French Financial Market Authority or the applicable

provisions of the French tax code were amended.

Pursuant to Article 235 ter ZD of the French tax code, purchases of equity instruments or similar securities of a French

company listed on a regulated market of the EU or on a foreign regulated market formally recognized as such by the French

Financial Market Authority (the “AMF”) are subject to a French tax on financial transactions at a rate of 0.4% following the

adoption of the Finance bill for 2025 provided that the issuer’s market capitalization exceeds 1 billion euros as of December 1

of the year preceding the taxation year. On the date hereof, the NYSE is not formally recognized as a foreign regulated market

by the AMF.

If the NYSE were to be formally recognized as a foreign regulated market by the AMF in the future, or if Article 235 ter

ZD of the French tax code were amended to include the NYSE as a foreign regulated market, the French financial transaction

tax could be due on purchases of ordinary shares of the Company.

GENERAL RISKS

Disruptions or failures in our IT systems, or failure to protect our IT systems against cyber-attacks or information

security breaches, could result in reputational harm and other negative consequences and have a material adverse effect

on our business, financial conditions and results of operations.

We rely on internal and externally managed information technology (“IT”) systems to effectively manage and operate our

business, including such processes as data collection, accounting, financial reporting, communications, supply chain, order

entry and fulfillment, other business processes, and in operating our equipment. The failure of any our IT systems to perform

efficiently could disrupt our business and could result in transaction errors, processing inefficiencies, limited equipment

utilization, the loss of sales, customers, or intellectual property, causing our business and financial results to suffer. A failure in,

or breach of, our IT 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 periodically adjust our security measures and procedures to allow us to investigate and

seek to promptly remediate any information security issues. Information security risks continue to grow with the ongoing

proliferation of new technologies, such as artificial intelligence (“AI”) and machine learning, and the sophistication and high

level of activity of perpetrators of cyber-attacks, particularly during periods of domestic and international conflict, and

geopolitical tension. Moreover, with remote working remaining an option for our personnel, we continue to have a dependency

on remote equipment and connectivity infrastructure to access critical business systems that may be subject to failure,

disruption, or unavailability, and which increases our exposure to security breaches. Any of these events could negatively

impact our operations. We did not have any significant security incidents or intrusions in 2025 that adversely impacted our

systems or business.

We evaluate our IT systems and security processes on a continuing basis, including conducting third party security

assessments. We continue to make investments and adopt measures designed to enhance our protection, detection, response,

and recovery capabilities, and to mitigate potential risks to our technology, products, services, and operations from potential

cyber-attacks. However, given the unpredictability, nature, and scope of cyber-attacks, it is possible that potential

vulnerabilities could go undetected for an extended period. We, and our suppliers, could potentially be subject to operational

disruption to our respective information systems, which could cause production downtime, operational delays or outages, other

adverse impacts on our operations or ability to provide products and services to our customers, the compromise of confidential

or otherwise protected information, misappropriation, destruction or corruption of data (including customer and order data),

security breaches, other manipulation or improper use of our or third-party systems, networks or products. Any of the

aforementioned events could lead to financial losses from remedial actions, loss of business or potential liability, and/or damage

our reputation, which could have a material adverse effect on our competitive position, results of operations, cash flows or

financial condition. The use of new and evolving technologies, such as AI, presents risks and challenges that can impact our

business. Unauthorized use or misuse of AI by the Company's employees, vendors or others may result in the disclosure of

confidential company or customer data, reputational harm, privacy law violations, cybersecurity risks, and legal liability.

For further information regarding our cybersecurity risk management processes see Item 1C. Cybersecurity.

We may be exposed to fraud, misconduct, corruption, or other illegal activity which could harm our reputation

and our financial results.

We may be exposed to fraud, misconduct, corruption or other illegal activity by our employees, independent contractors,

consultants, commercial partners, and vendors. Despite the internal controls and the policies and procedures we have developed

and implemented to comply with anti-bribery, anti-money laundering, anti-corruption and other laws, violations or misconduct

by these parties could include intentional, reckless, and negligent conduct, which can be difficult to detect, and such policies

and procedures may not be effective in all instances to prevent these actions.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

Process

We have established a cybersecurity risk management process that aims to identify, assess, mitigate, monitor, and report

on the IT risks and cybersecurity threats that may affect our business objectives, performance, reputation, and compliance. We

conduct an overall annual cybersecurity risk assessment to identify and prioritize the IT and IT security risks that may impact

our business strategy, results of operations, and financial condition. We have processes and controls that help prevent, detect,

and recover from security incidents and we also perform regular security assessments to test the resilience of our IT systems

and networks against potential attacks and vulnerabilities. Our employees are provided awareness training on a regular basis to

help them identify, avoid, mitigate, and report cybersecurity threats.

We use security assessments, penetration testing, and table-top or red teaming exercises with third parties to assess our

security posture and to improve our processes on a continuous basis. We also use our Internal Audit function to conduct

additional reviews and assessments. Our third-party service providers are subject to security risk assessments at the time of

onboarding, on a continuous basis and upon detection of an increase in risk profile. In addition, we require our providers to

meet appropriate security requirements, controls and responsibilities and to investigate security incidents that have impacted

such providers, as appropriate.

Management

Our Chief Information Officer/Chief Digital Officer (“CIO/CDO”), together with the Company’s security team, is

responsible for assessing, monitoring, and managing our cybersecurity risks. Our CIO/CDO has significant experience in IT

security, information security, and cybersecurity, with nearly two decades of experience and having served in a variety of senior

roles at the Company (and others) prior to serving as CIO/CDO. Our CIO/CDO also has experience with implementing various

security and infrastructure transformation and improvement programs.

The Company has an Enterprise Risk Management (“ERM”) Committee and process in place that reviews and evaluates

the overall risks to the Company, including its cybersecurity risks. The ERM process has the input of senior management and

other internal stakeholders, and the cybersecurity risk management process is integrated into our ERM review. Cybersecurity

risks to the Company are reviewed, evaluated, and discussed on a quarterly basis and, when necessary, on an ad-hoc basis with

our Executive Committee and other members of the management team.

We maintain controls and procedures that are designed to promote prompt review and escalation of certain cybersecurity

incidents so that decisions regarding reporting and public disclosure of such incidents can be made in a timely manner to

comply with cybersecurity incident reporting requirements.

Board of Directors

Our Board of Directors, through its Audit Committee, oversees the management of the Company’s cybersecurity

program and risks from cybersecurity threats. Our Audit Committee receives annual reports on cybersecurity risks resulting

from risk assessments, progress of risk reduction initiatives, external auditor feedback, internal audit reports on IT, IT security

and cybersecurity-related topics, control maturity assessments, and relevant internal and industry cybersecurity incidents. The

CIO/CDO also informs the Audit Committee on the prevention, detection, mitigation, and remediation of cybersecurity

incidents, including significant security risks and information security vulnerabilities. The Audit committee reports any

significant matters to the Board of Directors.

Risks

We rely on our IT systems to effectively manage and operate our business, including such processes as data collection,

accounting, financial reporting, communications, supply chain, order entry and fulfillment, other business processes, and in

operating our equipment. A cybersecurity incident could disrupt our business and could result in transaction errors, processing

inefficiencies, limited equipment utilization, the loss of sales, customers, or intellectual property, causing our business and

financial results to suffer. Although such risks have not materially affected our business, financial conditions, results of

operations or reputation to date, we have, from time-to-time experienced cybersecurity incidents in the normal course of

business. For more information regarding the risks we face from cybersecurity threats, please see "Item 1A. Risk Factors".

Item 3. Legal Proceedings

The Company is involved, and may become involved, in various lawsuits, claims and proceedings relating to customer

claims, product liability, employee and retiree benefit matters, and other commercial matters. The Company records provisions

for pending litigation matters when it determines that it is probable that an outflow of resources will be required to settle the

obligation, and such amounts can be reasonably estimated. In some proceedings, the issues raised are or can be highly complex

and subject to significant uncertainties and amounts claimed are and can be substantial. As a result, the probability of loss and

an estimation of damages are and can be difficult to ascertain. From time to time, asbestos-related claims are also filed against

us, relating to historic asbestos exposure in our production process. We have made reserves for potential occupational disease

claims for a total of $11 million as of December 31, 2025. 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.

Item 4. Mine Safety Disclosures

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity

Securities.

Overview

The Company's ordinary shares are listed on the NYSE under the symbol CSTM. We began trading on the NYSE on

May 23, 2013 through a public offering in the United States and our ordinary shares continue to be listed on the NYSE. For

more information on our shares see our Articles of Association contained in Exhibit 3.1 to this Annual Report and "Description

of Securities Registered under Section 12 of the Exchange Act" filed as Exhibit 4.1 to this Annual Report.

We maintain a website at www.constellium.com, where we make available free of charge our annual reports on Form 10-

K, quarterly reports on Form 10-Q, current reports on Form 8-K, Proxy Statements and amendments to such reports filed or

furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (the “Exchange Act”) as soon as

reasonably practicable after we electronically file such material with, or furnish it to, the SEC.

Holders of Record

As of January 30, 2026, 126,657,721 of our outstanding ordinary shares were held by one holder of record in the United

States as represented by our registrar and transfer agent and 8,412,050 of our outstanding ordinary shares were held by three

holders of record outside the United States. As many of our shares are held by brokers and other institutions on behalf of

shareholders, we are unable to estimate the total number of beneficial holders of our ordinary shares represented by these record

holders.

Dividend Policy

Our Board of Directors periodically explores the potential adoption of a dividend program. Any proposal of our Board of

Directors to declare and pay 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 obligations, future prospects and contractual restrictions applying to the payment of dividends and other

considerations that our Board of Directors considers to be relevant. The Board of Directors has no current intention to adopt a

dividend program, and no assurances can be made that any future dividends will be paid on the ordinary shares.

Under French law, dividends are approved by the shareholders at a shareholders’ meeting. All calculations to determine

the amounts available for dividends or other distributions will be based on our statutory financial statements which are, as a

holding company, different from our consolidated financial statements and which are prepared in accordance with French

GAAP because we are a French company. Dividends may only be paid by a French Societas Europaea such as the Company

out of "distributable profits," plus any distributable reserves and "distributable premium" that the shareholders decide to make

available for distribution, other than those reserves that are specifically required by law to be maintained.

"Distributable profits" consist of the unconsolidated net profits of the relevant company for each fiscal year, as increased

or reduced by any profit or loss carried forward from prior years.

"Distributable premium" refers to the contribution paid by the shareholders in addition to the par value of their shares for

their subscription that the shareholders decide to make available for distribution.

The Board of Directors may approve the distribution of interim dividends before the approval by the shareholders of the

financial statements for the relevant fiscal year when the interim balance sheet, established during or at the close of such year

and certified by the auditors, reflects that the company has earned distributable profits since the close of the previous fiscal

year, after recognizing the necessary depreciation and provisions and after deducting prior losses, if any, and the sums to be

allocated to reserves, as required by French law and the Company’s Articles of Association, and including any retained

earnings. The amount of such interim dividends may not exceed the amount of the profit so defined. The distribution of interim

dividends decided by the Board of Directors must be ratified by the next general shareholders’ meeting. In addition, restrictions

contained in agreements governing the Company's indebtedness may limit our ability to pay dividends on the Company's

ordinary shares and the ability of our subsidiaries to pay dividends to the Company. Future indebtedness that we may incur may

contain similar restrictions.

According to the Company's Articles of Association, distributions payable in cash are to be approved in euros and paid (i)

in euros for the holders of shares under the French Register and (ii) in U.S. dollars for the holders of shares under the U.S.

Register. For the purposes of the payment of the dividend in U.S. dollars, the general shareholders’ meeting or, as the case may

be, our Board of Directors set the reference date to be considered for the euro / U.S. dollar exchange rate.

Dividends (if any) shall be paid within nine months after the end of the fiscal year. Cash dividends and other distributions

that have not been collected within five years after the date on which they became due and payable will revert to the French

State.

French exchange control regulations currently do not limit the amount of payments that we may remit to non-residents of

France. Laws and regulations concerning foreign exchange controls do require, however, that all payments or transfers of funds

made by a French resident to a non-resident be handled by an accredited intermediary.

Recent Sales of Unregistered Equity Securities

None.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

On February 21, 2024, the Company announced that the Board of Directors authorized a three-year share repurchase

program of up to $300 million of the Company’s outstanding shares of ordinary shares, expiring on December 31, 2026. Under

this program, the Company may purchase shares from time to time for cash in open market transactions or in privately

negotiated transactions, in accordance with applicable state and federal securities laws and in compliance with applicable

provisions of French corporate law, and it may make all or part of the purchases pursuant to Rule 10b5-1 plans. The timing and

the amount of repurchases, if any, will be determined based on the Company’s evaluation of market conditions, capital

allocation alternatives and other factors. The share repurchase program does not require the Company to acquire any dollar

amount or number of shares of Constellium ordinary shares and may be modified, suspended, extended or terminated by the

Company’s Board of Directors at any time without prior notice. To execute the full share repurchase program, the Company

seeks shareholder approval annually at its Annual General Meeting.

As of December 31, 2025, the Company had approximately $106 million remaining under the Company’s share

repurchase program. Since the inception of the share repurchase program up to December 31, 2025, approximately 13.5 million

shares have been repurchased under the program for approximately $194 million. In the fourth quarter of 2025, approximately

2.4 million shares were repurchased under the plan for approximately $40 million.

The following table provides information about purchases of its ordinary shares by the Company during the quarter

ended December 31, 2025.


Period	Total number of shares purchased	Average price paid per share (in U.S. dollars)	Total number of shares purchased as part of publicly announced plans or programs	Maximum approximate dollar value of shares that may yet be purchased under the program

Item 6. Reserved

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis is based principally on our audited Consolidated Financial Statements prepared

under U.S. GAAP at December 31, 2025 and 2024, and for the three years ended December 31, 2025 included elsewhere in this

Annual Report, and is provided to supplement the audited Consolidated Financial Statements and the related notes to help

provide an understanding of our financial condition, changes in financial condition, results of our operations, and liquidity.

The following discussion is to be read in conjunction with our audited Consolidated Financial Statements prepared under U.S.

GAAP and the notes thereto, which are included elsewhere in this Annual Report.

The following discussion and analysis includes forward-looking statements. These forward-looking statements are

subject to risks, uncertainties and other factors that could cause our actual results to differ materially from those expressed or

implied by our forward-looking statements. Factors that could cause or contribute to these differences include, but are not

limited to, those discussed below and elsewhere in this Annual Report. See in particular “Forward-Looking Statements” and

“Item 1A. Risk Factors. This section discusses items pertaining to and comparisons of financial results between fiscal years

2025 and 2024. A discussion of and comparisons between fiscal years 2024 and 2023 financial results can be found in

“Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7. of the

Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on February 28,

2025.

Amounts presented in the audited Consolidated Financial Statements are expressed in millions of U.S. dollars, except as

otherwise stated. Shipments are expressed in thousands of metric tons. Amounts may not sum due to rounding.

Management review and outlook

Constellium delivered strong results in 2025 despite the uncertain macroeconomic and end market environment. Looking

across our end markets, packaging demand remained healthy during 2025, and we continued to benefit from improved

operational performance at Muscle Shoals. Aerospace demand was lower driven by continued destocking of aluminum products

in the global Aerospace supply chain, though demand for high value add products remain healthy. Automotive demand

remained weak in Europe and relatively stable in North America, and in the fourth quarter we benefited from increased demand

due to short-term supply shortages in the U.S. Industrial market conditions in North America and Europe became more stable,

and our shipments in Europe improved in the year given the post-flood recovery in Valais (Switzerland). Following the tariff

announcements in 2025, market aluminum prices (LME price + Midwest Premium) have risen sharply in North America, and

certain spot scrap aluminum spreads have improved from previous historically tight levels. We expect recent demand trends in

our end markets to continue into the early part of 2026 and the overall macroeconomic environment to remain relatively stable,

and we expect to benefit from recent market dynamics, including supply shortages for automotive rolled products as well as

improved scrap spreads in North America. We are proactively managing the business to the current environment. We remain

focused on executing on our strategy, driving operational performance, controlling costs, generating Free Cash Flow and

increasing shareholder value.

For the year ended December 31, 2025, our operating segments represented the following percentages of total Revenue

and Segment Adjusted EBITDA:


	Year ended December 31, 2025
(as a % of total)	Revenue		Segment Adjusted EBITDA
A&T		23%		47%
P&ARP		60%		49%
AS&I		19%		10%
H&C (1)		—%		(6)%
Total		100%		100%

(1) Holdings and Corporate primarily reflects incidental revenues and unallocated corporate activities.

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

Economic, Geopolitical and General Market Conditions

We are directly impacted by the economic conditions that affect our customers and the markets in which they operate.

General economic and market conditions such as the level of disposable income, the level of inflation, the rate of economic

growth, the rate of unemployment, the rapid development of technology, interest rates, exchange rates and currency devaluation

or revaluation influence consumer confidence and consumer purchasing power. These factors, in turn, influence the demand for

our products in terms of total volumes and prices that can be charged. We attempt to respond to the variability of economic

conditions through the terms of our contracts with our customers as well as cost control.

During the year ended December 31, 2025, we continued to monitor geopolitical and economic instability globally.

During the fourth quarter, there was continued uncertainty related to tariffs and trade conditions, and their short and long-term

impacts on the Company. Global and regional economies continue to be impacted by armed conflicts, sanctions, and volatility.

While it is difficult to predict the impact of these events, we continuously monitor them and develop contingency plans and

counter measures as necessary to seek to address adverse effects or disruptions to our operations as they arise.

Although a number of our end-markets are cyclical in nature, we believe that the diversity of our portfolio and the secular

growth trends we are experiencing in many of our end-markets will help the Company weather these economic cycles. In our

three principal end-markets of aerospace, packaging and automotive:

•Aerospace demand has stabilized following the sharp recovery post-COVID although the supply chain continues to

experience destocking of aluminum products. We continue to believe that the long-term trends of increased

passenger air traffic and fleet replacements with newer and more fuel efficient aircraft, along with new military and

space programs, will help support favorable long-term demand conditions.

•Historically, demand for aluminum can packaging has been fairly resilient during various economic cycles. We

believe canstock has an attractive long-term growth outlook driven in part by increased consumer preference for

aluminum cans as a beverage packaging material of choice.

•Automotive vehicle sales tend to fluctuate with the general economic cycle and in recent years have also been

impacted by global supply chain disruptions, the tariff and trade environment, affordability, customer offerings and

consumer preference. However, aluminum demand has increased in recent years, driven by the vehicle

lightweighting trend to improve energy efficiency, reduce emissions and enhance vehicle safety, which has resulted

in more aluminum usage for new car models. We expect the lightweighting trend to continue in the future.

Product Price and Margin

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

(iii) a conversion margin.

Aluminum Prices

The price we pay for primary aluminum includes the LME price and regional premiums such as the Midwest premium

for metal purchased in the U.S. or the Rotterdam premium for metal purchased in Europe. Both the LME price and the regional

premiums can be volatile. Our business model aims to pass through aluminum price exposure by pricing our products to include

the cost of the metal purchased and hedging any remaining exposure to the extent possible to achieve aluminum price

neutrality.

Aluminum prices have risen in 2025, especially in the U.S. following the tariff announcements. The average LME

transaction price, Rotterdam premium and Midwest premium per ton of primary aluminum for the years ended December 31,

2025 and 2024 are presented below.


	Year ended December 31,		Percent changes

(U.S. dollars per ton)	2025	2024	2025 vs 2024

Average LME transaction price	2,632	2,419	9%
Average Midwest premium	1,298	432	200%
Average all-in aluminum price U.S.	3,930	2,851	38%

Average LME transaction price	2,632	2,419	9%
Average Rotterdam premium	252	314	(20)%
Average all-in aluminum price Europe	2,884	2,733	6%

Volumes

The profitability of our business is determined, in part, by the volume of tons processed and sold. Increased production

volumes will generally result in lower per unit costs due to the fixed costs structure of our operations. Higher volumes sold will

generally result in additional revenue and associated profitability. Demand trends across key sectors — aerospace, packaging

and automotive — contribute to our production planning. Seasonal fluctuations and macroeconomic conditions are important

factors in volume variability.

Personnel Costs

Our operations are labor intensive. Personnel costs include the salaries, wages and benefits of our employees, as well as

costs related to temporary labor. During our seasonal peaks and the summer months, we have historically increased our

temporary workforce to compensate for increased volume of activity and vacation schedules. Personnel costs generally increase

and decrease with the expansion or contraction in production levels. Personnel costs also generally increase in periods of higher

inflation.

Energy

Our operations require substantial amounts of energy to run, primarily electricity and natural gas. The magnitude of

energy costs depends on the energy supply and demand relationships in the regions we operate in.

Currency

We are a global company with operations in the United States, France, Germany, Switzerland, the Czech Republic,

Slovakia, Spain, Mexico, Canada and China. As such, we are exposed to transaction and translation impacts.

Transaction impacts arise when our businesses transact in a currency other than their own functional currency. As a

result, we are exposed to foreign exchange risk on payments and receipts in multiple currencies. Where we have multiple-year

sales agreements in U.S. dollars by euro-functional currency entities, we have typically entered into derivative contracts to

forward sell U.S. dollars to match these future sales. With the exception of certain derivative instruments entered into to hedge

the foreign currency risk associated with the cash flows of certain highly probable forecasted sales, which we have designated

for hedge accounting, hedge accounting is not applied to such ongoing commercial transactions. The mark-to-market impact

associated with these transactions is therefore recorded in Other Gains and Losses - net.

Translation impacts result from the translation at each period of the results of functional currency entities other than U.S.

dollars into our reporting currency, the U.S. dollar.

Revenue

For the year ended December 31, 2025, Revenue increased 15% to $8,449 million from $7,335 million for the year ended

December 31, 2024. This increase reflected higher shipments and higher revenue per ton, including higher metal prices.

For the year ended December 31, 2025, sales volumes increased 4% to 1,495 kt from 1,438 kt for the year ended

December 31, 2024. This increase reflected a 1% decrease in volumes for A&T, a 6% increase in volumes for P&ARP and

stable volumes for AS&I.

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

Cost of Sales

For the year ended December 31, 2025, Cost of sales increased 14% to $7,262 million from $6,397 million for the year

ended December 31, 2024. This increase in Cost of sales was primarily driven by an 18% increase in raw materials and

consumables used primarily as a result of higher metal prices and higher sales volumes.

Selling and Administrative Expenses

For the year ended December 31, 2025, Selling and administrative expenses increased 6% to $332 million from $313

million for the year ended December 31, 2024. The increase was primarily driven by an increase in labor costs, partially offset

by lower headcount.

Research and Development Expenses

For the year ended December 31, 2025, Research and development expenses increased 4% to $51 million from $49

million for the year ended December 31, 2024. This increase was primarily driven by an increase in labor costs and the impact

of foreign exchange translation.

Other Gains and Losses - net

The following table provides an analysis of realized and unrealized gains and losses by nature of exposure:


	For years ended December 31,
(in millions of U.S. dollars)	2025	2024

Realized gains / (losses) on foreign currency derivatives - net	11	(10)
Realized gains on commodities derivatives - net	8	22
Realized gains on derivatives	19	12

Unrealized gains / (losses) on foreign currency derivatives - net	28	(20)
Unrealized gains on commodities derivatives - net	28	19
Unrealized gains / (losses) on derivatives at fair value through profit and loss - net	56	(1)

Realized gains or losses relate to financial derivatives used by the Group to hedge underlying commercial and commodity

transactions. Realized gains and losses on these derivatives are recognized in Other Gains and Losses - net and are offset by the

commercial and commodity transactions accounted for in Revenue and Cost of sales.

Unrealized gains or losses relate to financial derivatives used by the Group to hedge forecasted and/or committed

commercial and commodity transactions for which hedge accounting is not applied. Unrealized gains or losses on these

derivatives are recognized in Other Gains and Losses - net and are intended to offset the change in the value of forecasted and/

or committed transactions which are not yet accounted for.

Changes in realized and unrealized gains / (losses) on derivatives for the year ended December 31, 2025 as compared to

the year ended December 31, 2024 primarily reflected the fluctuation in foreign exchange, partially offset by the fluctuation in

commodity prices.

Other Gains and Losses, net are further discussed in Note 5 to the audited Consolidated Financial Statements.

Finance Costs, net

For the year ended December 31, 2025, finance costs, net decreased 2% to $109 million from $111 million for the year

ended December 31, 2024. This decrease primarily reflected net fluctuation in realized and unrealized gains and losses on

liquidity foreign exchange derivatives and underlying net debt, partially offset by higher interest expense. In the year ended

December 31, 2024, Finance costs, net also included $3 million of write-off of unamortized issuance costs related to the

redemption of our Senior Notes that were due in 2026.

Income Tax

For the years ended December 31, 2025 and 2024, income tax expense totaled $133 million and $75 million,

respectively. Our effective tax rate was 32.6% and 55.6% of our Income before tax for the years ended December 31, 2025 and

2024, respectively. The difference between the effective tax rate and the statutory tax rate of 25.82% for the year ended

December 31, 2025 and 2024, was primarily due to the geographical mix of the pre-tax results, losses in certain jurisdictions

where a full valuation allowance was recorded and the United States Base Erosion Anti-Abuse Tax. Additionally, the year

ended December 31, 2025 includes the impact of the surtax in France enacted in February 2025.

A&T

For the year ended December 31, 2025, revenue in our A&T segment increased 8% to $1,968 million from $1,816

million for the year ended December 31, 2024, reflecting higher revenue per ton, including higher metal prices, partially offset

by lower shipments. A&T shipments were down 1%, or 2 kt, due to lower Aerospace rolled products shipments, partially offset

by higher Transportation, Industry and Defense rolled products shipments.

P&ARP

For the year ended December 31, 2025, revenue in our P&ARP segment increased 21% to $5,078 million from $4,196

million for the year ended December 31, 2024, reflecting higher shipments and higher revenue per ton, including higher metal

prices. P&ARP shipments were up 6%, or 59 kt, due to higher Packaging rolled products shipments, partially offset by lower

Automotive and Specialty rolled products shipments.

AS&I

For the year ended December 31, 2025, revenue in our AS&I segment increased 10% to $1,579 million from $1,432

million for the year ended December 31, 2024, reflecting higher revenue per ton, including higher metal prices, and stable

shipments, as lower Automotive extruded product shipments were offset by higher Other extruded products shipments.

Segment Adjusted EBITDA

In considering the financial performance of the business, we analyze the primary financial performance measure of

Segment Adjusted EBITDA in all of our business segments. Our Chief Operating Decision Maker, as defined under Accounting

Standards Codification ("ASC") Topic 280 - Segment reporting, measures the profitability and financial performance of our

operating segments based on Segment Adjusted EBITDA.

Segment Adjusted EBITDA is defined as income from continuing operations before income taxes, results from joint

ventures, net finance costs, other expenses and depreciation and amortization as adjusted to exclude restructuring costs,

impairment charges, unrealized gains or losses on derivatives and on foreign exchange differences on transactions that do not

qualify for hedge accounting, metal price lag (as defined hereafter), share-based compensation expense, non-operating gains /

(losses) on pension and other post-employment benefits, factoring expenses, effects of certain purchase accounting adjustments,

start-up and development costs or acquisition, integration and separation costs, certain incremental costs and other exceptional,

unusual or generally non-recurring items.

The following table sets forth the Segment Adjusted EBITDA for our reportable segments for the periods presented:


	For years ended December 31,
(in millions of U.S. dollars and as a % of revenue)	2025		2024

A&T	339	17%	292	16%
P&ARP	353	7%	242	6%
AS&I	72	5%	74	5%

Refer to Revision of certain disclosures in previously issued financial statements within Note 1 to the audited

Consolidated Financial Statements for information regarding the A&T Segment Adjusted EBITDA for the year ended

December 31, 2024.

The reconciliation of Segment Adjusted EBITDA is disclosed in Note 3 to the audited Consolidated Financial

Statements.

The following table presents the primary drivers for changes in Segment Adjusted EBITDA for each of our three

reportable segments:


(in millions of U.S. dollars)	A&T	P&ARP	AS&I
Segment Adjusted EBITDA for the year ended December 31, 2024	292	242	74

Costs	74	34	2
Foreign exchange and other	9	9	2
Segment Adjusted EBITDA for the year ended December 31, 2025	339	353	72

A&T

For the year ended December 31, 2025, Adjusted EBITDA in our A&T segment increased 16% to $339 million from

$292 million for the year ended December 31, 2024, primarily as a result of lower operating costs and favorable impact from

foreign exchange translation, partially offset by lower volumes and unfavorable price and mix. In the year ended December 31,

2024, Segment Adjusted EBITDA included a $13 million negative impact from the flood in Valais (Switzerland). For the year

ended December 31, 2025, Segment Adjusted EBITDA per ton increased 17% to $1,634 from $1,395 for the year ended

December 31, 2024.

P&ARP

For the year ended December 31, 2025, Adjusted EBITDA in our P&ARP segment increased 46% to $353 million from

$242 million for the year ended December 31, 2024, primarily as a result of higher volumes in North America with improved

Muscle Shoals performance, favorable price and mix, favorable metal costs, and favorable impact from foreign exchange

translation. In the year ended December 31, 2024, Muscle Shoals results were impacted by a weather-related event in January

2024. For the year ended December 31, 2025, Segment Adjusted EBITDA per ton increased 38% to $325 from $236 for the

year ended December 31, 2024.

AS&I

For the year ended December 31, 2025, Adjusted EBITDA in our AS&I segment decreased 3% to $72 million from

$74 million for the year ended December 31, 2024, primarily as a result unfavorable price and mix and unfavorable impact

from tariffs, partially offset by a customer compensation for underperformance of an automotive program and lower operating

costs. In the year ended December 31, 2024, Segment Adjusted EBITDA included a $20 million negative impact from the flood

in Valais (Switzerland). For the year ended December 31, 2025, Segment Adjusted EBITDA per ton decreased 3% to $357

from $367 for the year ended December 31, 2024.

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.

Our primary requirements for liquidity and capital resources, besides our growth initiatives, are working capital, capital

expenditures, principal and interest payments on our outstanding debt, and other general corporate needs. Historically, these

cash requirements have been met through cash provided by operating activities and cash and cash equivalents, as well as

strategic financing arrangements. As of December 31, 2025, the Company was not party to any off-balance sheet arrangements

that have had or are reasonably likely to have a current or future material effect on our financial condition, results of operations,

liquidity, capital expenditures, or capital resources. Based on our current and anticipated levels of operations, and the condition

in our markets and industry, we believe that our cash flows from operations, cash on hand, new debt issuances or refinancing of

existing debt facilities, and availability under our factoring and revolving credit facilities will enable us to meet our working

capital, capital expenditures, debt service and other funding requirements for the short-term and long-term.

At December 31, 2025, our material short-term and long-term contractual cash obligations consist of our debt, lease

commitments and related interest and capital expenditures, which are detailed in Note 15.4 and Note 20 of our audited

Consolidated Financial Statements. In addition, we have material pension and other post-employment obligations as we operate

various pension plans for the benefit of our employees across a number of countries as detailed in Note 17 of our audited

Consolidated Financial Statements.

It is our policy to hedge all highly probable or committed foreign currency operating cash flows. As we have significant

third-party future receivables denominated in U.S. dollars, we generally enter into combinations of forward contracts with

financial institutions, selling forward U.S. dollars against euros.

When we are unable to align the price and quantity of physical aluminum purchases with that of physical aluminum

sales, it is also our policy to enter into derivative financial instruments to pass through the exposure to metal price fluctuations

to financial institutions.

As the U.S. dollar depreciates (appreciates) against the euro or the LME price for aluminum increases (decreases), the

derivative contracts related to transactional hedging entered into with financial institution counterparties will have a positive

(negative) mark-to-market.

In addition, we borrow in a combination of the U.S. dollar and euro. When the external currency mix of our debt does not

match the mix of our assets, we use foreign currency derivatives to balance the risk.

Our financial institution counterparties may require margin calls should our negative mark-to-market exceed a pre-agreed

contractual limit. In order to protect the Group from the potential margin calls for significant market movements, we maintain

additional cash or availability under our various borrowing facilities, we enter into derivatives with a large number of financial

counterparties and we monitor potential margin requirements on a daily basis for adverse movements in the U.S. dollar against

the euro and in aluminum prices. There were no margin calls at December 31, 2025 and 2024.

At December 31, 2025, we had $866 million of total liquidity, comprised of $120 million in cash and cash equivalents,

$541 million of availability under our Pan-U.S. ABL facility, $118 million of availability under the committed asset-based

facility for our French subsidiaries (“French Inventory Facility”) and $87 million of availability under our factoring

arrangements.

Factored receivables under non-recourse arrangements were $430 million and $376 million as of December 31, 2025 and

2024, respectively, primarily as result of unfavorable fluctuation in foreign exchange.

Cash Flows

The following table summarizes our cash flows from/(used in) our operating, investing and financing activities for the

years ended December 31, 2025 and 2024:


	For years ended December 31,
(in millions of U.S. dollars)	2025	2024

Net Cash Flows from / (used in)
Operating activities	489	301
Investing activities	(309)	(313)
Financing activities	(215)	(61)
Net (decrease) in cash and cash equivalents, excluding the effect of exchange rate changes	(35)	(73)

Net Cash Flows from Operating Activities

For the year ended December 31, 2025, net cash flows from operating activities were $489 million, a $188 million

increase from $301 million in the year ended December 31, 2024. This change primarily reflects a $225 million increase in cash

flows from operating activities before working capital and a $37 million decrease in cash flows from working capital usage.

For the year ended December 31, 2025, changes in working capital were attributable to (i) an increase in inventory of

$149 million, primarily driven by higher ending metal prices; (ii) an increase in trade receivables of $203 million primarily

driven by higher activity levels and higher ending metal prices; and (iii) an increase in trade payables of $168 million, primarily

driven by higher metal purchases due to higher activity levels and higher ending metal prices.

For the year ended December 31, 2024, changes in working capital were attributable to (i) an increase in inventory of

$24 million, primarily driven by higher ending metal prices; (ii) an increase in trade receivables of $50 million primarily driven

by higher ending metal prices, partially offset by lower shipments and by $85 million of deferred purchase price from factoring;

and (iii) a decrease in trade payables of $40 million, primarily driven by lower metal purchases due to lower activity levels,

partially offset by higher ending metal prices.

Net Cash Flows used in Investing Activities

For the years ended December 31, 2025 and 2024, net cash flows used in investing activities were $309 million and $313

million, respectively. Capital expenditures, net of Property, Plant and Equipment inflows were $311 million and $401 million,

respectively, and related primarily to maintenance investments in our manufacturing facilities as well as return-seeking and

growth projects such as investments in our recycling and casting capacities. For the years ended December 31, 2025 and 2024,

collection of deferred purchase price receivables under certain of our factoring agreements was $2 million and $85 million,

respectively.

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

Net Cash Flows used in Financing Activities

For the year ended December 31, 2025, net cash flows used in financing activities were $215 million, primarily reflecting

share repurchases, repayment of the borrowings under the Pan-U.S. ABL facility as well as realized foreign exchange losses on

net debt hedging instruments due to the weakening of the U.S. dollar. During the year ended December 31, 2025, Constellium

repurchased 8.9 million ordinary shares of the Company for $115 million.

For the year ended December 31, 2024, net cash flows used in financing activities were $61 million, primarily reflecting

share repurchases, the impact of the August 2024 refinancing, and borrowings under the Pan-U.S. ABL facility. During the year

ended December 31, 2024, Constellium repurchased 4.6 million ordinary shares of the Company for $79 million. In August

2024, Constellium issued $350 million of 6.375% Senior Notes due 2032 and €300 million of 5.375% Senior Notes due 2032,

using the proceeds and cash on hand to redeem the remaining portion of the $250 million of 5.875% Senior Notes due 2026 and

the €400 million of 4.250% Senior Notes due 2026.

Principal Accounting Policies, Critical Accounting Estimates and Key Judgments

Our principal accounting policies and new standards and interpretations not yet adopted are set out in Note 1 to the

audited Consolidated Financial Statements, which appear in this Annual Report.

The preparation of our consolidated financial statements requires management to make judgments, estimates and

assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures, as

well as the disclosure of contingent liabilities. These judgments, estimates and assumptions are based on management’s best

knowledge of the relevant facts and circumstances, giving consideration to previous experience. However, actual results may

differ from the amounts included in the audited 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. The Company continuously reviews its significant assumptions and estimates in light of

the uncertainty associated with the global geopolitical and macroeconomic conditions and their potential direct and indirect

impacts on its business and its financial statements. There can be no guarantee that our assumptions will materialize or that

actual results will not differ materially from estimates.

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, and its determination requires the application of judgment. Assumptions used and

judgments made in determining the defined benefit obligations and net pension costs include discount rates, the expected long-

term rate of return on plan assets, rates of future compensation increase, and the criteria considered to determine when a plan

amendment has occurred.

Any material changes in these assumptions could result in a significant change in Pensions and other post-employment

benefit obligations and in employee benefit expenses recognized in the Consolidated Income Statement or actuarial gains and

losses recognized in Other Comprehensive Income. Details of the key assumptions made and judgments applied are set out in

Note 17 to our audited Consolidated Financial Statements.

Deferred income taxes

Significant judgment is also 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 (greater than 50%) that the

deferred tax assets will be utilized. If it is determined that it is more likely than not that some or all of the deferred tax assets

will not be realized, a valuation allowance is recognized to reduce the carrying amount of these assets. The deferred tax assets

will be ultimately utilized to the extent that sufficient taxable profits will be available in the years 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. A full valuation allowance is

recognized for deferred tax assets 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. Details of the key assumptions made and

judgments applied are set out in Note 7 to our audited Consolidated Financial Statements.

Impairment tests for property, plant and equipment

Long-lived assets, including property, plant and equipment are reviewed for impairment when facts and circumstances

indicate that the asset carrying value may not be recoverable from its undiscounted projected cash flows. Any impairment loss

is measured by comparing the carrying value of the asset to its fair value. Impairment tests on property, plant and equipment

depend on a number of assumptions, in particular market data, estimated future cash flows and discount rates. These

assumptions are subject to risk and uncertainty. Any material changes in these assumptions could result in a significant change

in any impairment of assets. Details of the key assumptions made and judgments applied, where applicable, are set out in Note

11 to our audited Consolidated Financial Statements.

Recently issued accounting standards

See Note 1 - General information and summary of significant accounting policies to our accompanying Consolidated

Financial Statements for a full description of recent accounting pronouncements, if applicable, including the respective

expected dates of adoption and expected effects on results of operations and financial condition.

Non-GAAP measures

Adjusted EBITDA is not a measure defined by GAAP. We believe the most directly comparable GAAP measure to

Adjusted EBITDA is our net income or loss for the relevant period.

Adjusted EBITDA is defined as income/(loss) from continuing operations before income taxes, results from joint

ventures, net finance costs, other expenses and depreciation and amortization as adjusted to exclude restructuring costs,

impairment charges, unrealized gains or losses on derivatives and on foreign exchange differences on transactions that do not

qualify for hedge accounting, share-based compensation expense, non-operating gains / (losses) on pension and other post-

employment benefits, factoring expenses, effects of certain purchase accounting adjustments, start-up and development costs or

acquisition, integration and separation costs, certain incremental costs and other exceptional, unusual or generally non-recurring

items.

We believe Adjusted EBITDA, as defined above, is useful to investors as it illustrates the underlying performance of

continuing operations by excluding certain non-recurring and non-operating items. Similar concepts of adjusted EBITDA are

frequently used by securities analysts, investors and other interested parties in their evaluation of our company and in

comparison to other companies, many of which present an adjusted EBITDA-related performance measure when reporting their

results.

Adjusted EBITDA has limitations as an analytical tool. It is not a measure defined by GAAP and therefore does not

purport to be an alternative to operating profit or net income as a measure of operating performance or to cash flows from

operating activities as a measure of liquidity. Adjusted EBITDA is not necessarily comparable to similarly titled measures used

by other companies. As a result, you should not consider Adjusted EBITDA in isolation from, or as a substitute analysis for, our

results prepared in accordance with GAAP.

The following table reconciles our net income to our Adjusted EBITDA:

_______________

(A)For the year ended December 31, 2025, we recognized impairment related to property, plant and equipment primarily in our Valais

extrusion operations and at 2 other AS&I facilities. For the year ended December 31, 2024, impairment related to property, plant and

equipment in our Valais operations.

(B)For the year ended December 31, 2025 and 2024 restructuring costs were related to cost reduction programs in the United States and in

Europe.

(C)For the year ended December 31, 2025, Other mainly includes $9 million of insurance proceeds and $9 million of losses resulting from

flooding in the Valais (Switzerland) facilities at the end of June 2024.

For the year ended December 31, 2024, Other mainly includes $45 million of insurance proceeds and $43 million of losses resulting from

flooding in the Valais (Switzerland) facilities at the end of June 2024, $4 million of insurance proceeds related to assets damaged in 2021

and $3 million gain from the acquisition of the non-controlling interests of Railtech Alu-Singen, as well as $6 million of costs associated

with non-recurring corporate transformation projects.

(D)Metal price lag represents the financial impact of the timing difference between when aluminum prices included within Constellium's

Revenue are established and when aluminum purchase prices included in Cost of sales are established, which is a non-cash financial

impact. The calculation of metal price lag adjustment is based on a standardized methodology applied at each of Constellium’s

manufacturing sites. Metal price lag is calculated as the average value of product purchased in the period, approximated at the market

price, less the value of product in inventory at the weighted average of metal purchased over time, multiplied by the quantity sold in the

period.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Our financial risk management strategy focuses on minimizing the cash flow impacts of volatility in foreign currency

exchange rates and commodity prices, while maintaining the financial flexibility the Company requires in order to successfully

execute its business strategy. We use derivative financial instruments as risk management tools only, and not for speculative

purposes.

Due to the Group’s capital structure and the nature of its operations, the Company is exposed to the following market

risks: foreign exchange, commodity price and interest rate risks.

Foreign exchange risk

We are a global company with operations in the United States, France, Germany, Switzerland, the Czech Republic,

Slovakia, Spain, Mexico, Canada and China. As our reporting currency is the U.S. dollar, our revenue and earnings have

exposure to a number of currencies, primarily the U.S. dollar, the euro, the Swiss franc and the Czech koruna.

Foreign exchange risk is the risk that the fair value or future cash flows of a currency exposure will fluctuate because of

changes in foreign exchange rates.

Net assets, earnings and cash flows are influenced by multiple currencies due to the geographic diversity of sales and the

countries in which the Company operates.

The Company has the following foreign exchange risk: (i) transaction exposures, which include commercial transactions

related to forecasted sales and purchases and on-balance sheet receivables/payables resulting from such transactions as well as

financing transactions related to external and internal net debt, and (ii) translation exposures, which relate to net investments in

entities whose functional currency is not the U.S. dollar that are converted in U.S. dollars in the Consolidated Financial

Statements. We engage in hedging activities to attempt to mitigate the effects of foreign currency transactions on our

profitability and cash flow.

Commercial transaction exposures

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. In Europe, a portion of our

revenue is denominated in the U.S. dollar while the majority of our costs incurred are denominated in local currencies.

The Company policy is to hedge committed and highly probable forecasted foreign currency commercial transactions.

The Company uses foreign exchange forwards and foreign exchange swaps for this purpose.

Financing transaction exposures

When the Company enters into intercompany loans and deposits, the financing is generally provided in the functional

currency of the subsidiary. The foreign currency exposure of the Company’s external funding and liquid assets is systematically

hedged either naturally through intercompany foreign currency loans and deposits or through foreign currency derivatives.

Foreign exchange sensitivity on commercial and financing transaction exposures

The largest exposures of the Company are related to the U.S. dollar/euro exchange rate in non-US dollar functional

currency entities. The table below summarizes the impact on income and equity (before tax effect) of a 10% strengthening of

the U.S. dollar versus the euro.


(in millions of U.S. dollars)	Effect on income before tax	Effect on pretax equity
Trade receivables	6	—
Trade payables	(1)	—
Derivatives on commercial transactions (A)	(43)	(32)
Net commercial transaction exposure	(38)	(32)
Cash in Bank and intercompany loans	99	—
Borrowings	(131)	—
Derivatives on financing transactions	32	—
Net financing transaction exposure	—	—
Total	(38)	(32)

(A)Gains or losses on the hedging instruments are expected to offset losses or gains on the underlying hedged forecasted sales that will be

reflected in future years when these sales are recognized. The impact on pretax equity of $(32) million relates to derivatives hedging

forecasted sales from 2026 to 2029 which are designated as cash flow hedges.

The amounts shown in the table above may not be indicative of future results since the balances of financial assets and

liabilities may change.

Translation exposures

As our reporting currency is the U.S. dollar, and the functional currencies of the businesses located outside of the United

States are primarily the euro, the Swiss franc and the Czech koruna, the results of the businesses located outside of the United

States must be translated each period to U.S. dollar. Accordingly, fluctuations in the exchange rate of the functional currencies

of our businesses located outside of the United States against the U.S. dollar have a translation impact on our results of

operations.

Foreign exchange impacts related to the translation of net investments in non-U.S. dollar functional currency subsidiaries

from functional currency to U.S. dollar, and of the related revenue and expenses, are not hedged as the Company operates in

these various countries on a permanent basis.

Foreign exchange sensitivity on translation exposures

The exposure relates to foreign currency translation of net investments in non-U.S. dollar functional currency subsidiaries

and arises mainly from operations conducted by euro functional currency subsidiaries.

The table below summarizes the impact on income and equity of a 10% strengthening of the U.S. dollar versus the euro

(on average rate for net income and closing rate for equity) for euro functional currency entities.


(in millions of U.S. dollars)	Effect on net income	Effect on equity
10% strengthening U.S. dollar versus euro	(15)	(45)

The amounts shown in the table above may not be indicative of future results since the balances of financial assets and

liabilities may change.

Commodity price risk

The Company is subject to the effects of market fluctuations in the price of aluminum, which is the Company’s primary

metal input and a significant component of its output. The Company is also exposed to variation in regional premiums and in

the price of copper, lithium, magnesium, manganese, silicon, silver or zinc, but in a less significant way.

The Company's risk management practices aim to mitigate our exposure to changing primary aluminum and regional

premium prices. Moreover, while we limit our exposure to unfavorable price changes, we also limit our ability to benefit from

favorable price changes. We do not apply hedge accounting for the derivative instruments we entered into in order to hedge our

exposure to changes in metal prices and the mark-to-market movements for these instruments are recognized in Other Gains

and Losses - net.

The Company's results are also impacted by fluctuations in the primary and scrap aluminum prices. We purchase large

amounts of scrap aluminum to manufacture some of our products because scrap usually trades at a discount to the market price

of primary aluminum (i.e. LME plus regional premiums). The difference between the price of primary aluminum and price of

scrap is referred to as the “scrap spread.” The scrap spread depends on regional scrap aluminum supply and overall market

demand. If the scrap spread widens and the price of primary aluminum remains static, this could have a favorable impact on our

Company's results, while the converse could lead to an unfavorable impact. Therefore, the Company's results could be impacted

by market conditions related to aluminum scrap and the effectiveness and timing of our scrap purchasing activities.

Aluminum prices are determined by worldwide forces of supply and demand and are volatile. We operate a pass–through

business model and therefore, to the extent possible, avoid taking aluminum price risk. In case of significant sustained increases

in the price of aluminum, the demand for our products may be affected over time.

The Company policy is to minimize exposure to aluminum price volatility by passing through the aluminum price risk to

customers and using derivatives where necessary. The company policy is to minimize exposure to aluminum price volatility by

pricing our products to include the cost of the metal purchased and hedging any remaining exposure through the use of financial

derivatives, to the extent possible. The hedging program intends to convert the price of the aluminum sales and purchases to be

on the same or similar floating basis. As a result, in a scenario where LME price increases, we have limited additional cash

requirements to finance the increased replacement cost of our inventory.

Temporary increases in inventory, to the extent material, are sold forward to the expected sales date to ensure the price

paid for the metal is recovered when it is sold.

The Company also enters into derivatives for copper, aluminum premium, silver and zinc to offset the commodity price

exposure inherent to certain sales and purchase contracts.

Our operations require substantial amounts of energy to run, primarily electricity and natural gas. The direction of energy

costs depends on the energy supply and demand relationships in the regions we operate in. The current geopolitical instability

continues to expose us to the risk of energy supply disruptions. In addition, sustainability trends are expected to put upward

pressure on energy costs over time. A significant increase in energy costs or disruption of energy supply could have a material

adverse effect on financial position, results of operations, and cash flows. In many instances, the Company purchases energy

fixed-price derivatives to lock in energy costs where a fixed price purchase contract is not possible.

Commodity price sensitivity: risks associated with derivatives

The net impact on earnings of a 10% increase in the market price of aluminum, based on the aluminum derivatives held

by the Company at December 31, 2025 (before tax), with all other variables held constant, was estimated to be a $35 million

gain. The balances of these financial instruments may change in future years, and therefore these amounts may not be indicative

of future results.

Interest rate risk

Interest rate risk is the risk that the fair value or future cash flows of financial instruments will fluctuate because of

changes in market interest rates. The Company’s interest rate risk arises principally from borrowings. Borrowings issued at

variable rates expose the Company to cash flow interest rate risk. Borrowings issued at fixed rates expose the Company to fair

value interest rate risk. At December 31, 2025, the Company’s borrowings were mainly at fixed rates.

Interest rate sensitivity: risks associated with variable-rate financial instruments

The impact on income before income tax of a 50 basis point increase or decrease in the EURIBOR or SOFR interest rates

as applicable, based on the variable rate financial instruments held by the Company at December 31, 2025 and 2024, with all

other variables held constant, was estimated to be approximately $3 million and $2 million for the years ended December 31,

2025, and December 31, 2024, respectively. However, the balances of such financial instruments may not remain constant in

future years, and therefore these amounts may not be indicative of future results.
