Agenda

• The market opportunity

• Challenges

• Solutions

• Industry leadership

2

• Global platforms: Carmakers demand that the same products be delivered to their production facilities worldwide, to support global platforms that are designed centrally. The percentage of vehicles built on global platforms will increase from 46% in 2014 to 63% in 2020

• Regulation: Shift in product needs to meet regulatory targets for fuel economy as well as passenger safety during crash events

• ArcelorMittal offers the specific solutionsto address these challenges

• ArcelorMittal maintains both its geographical and its technologicalleadership in the automotive market

Rigorous fuel economy standards

Global CO2 (or equivalent) regulation trends 2012-2025 US CAFE* rules (MPG)

• 2012-2025 rules are footprint driven – each vehicle has a mandated fuel economy standard based on track x wheelbase

• 2025 CAFE for Light Vehicle USA: 54.5 MPG based on projected 2025 fleet by EPA/NHTSA• Similar trend for passenger safety in a crash event

EU and US CO2 emission targets

By 2015 fuel economy rates have met but there is a greater challenge aheadBy 2015 fuel economy rates have met but there is a greater challenge ahead

Europe: On track to achieve the regulatory CO2 emissions targets• EU regulation of new car fleet average

CO2 emissions of 130 g/km by 2015 has been met in 2014 with an average of 123 g/km thanks to rapid progress in recent years

• Target of 95 g/km confirmed for 2021. The next targets are still under discussion

US: 2025 target is more challenging• The 2014 US new car fleet met the 2015

target (165 g/km) but require further improvements to meet the 2025 target of 97 g/km

• The US fleet is composed of larger cars making the CO2 target much harder to meet

What are laser welded blanks?

Applying the necessary properties where they are neededApplying the necessary properties where they are needed

• Laser welded blanks are two or more flat steel sheets welded together by a laser. These sheets can:• Have different thicknesses• Be made of different alloys• Have different coatings

• Using laser welded blanks, automotive engineers can design parts with the necessary properties where they are needed, optimizing weight and safety

ArcelorMittal market shares

Europe

• ArcelorMittal is maintaining or even increasing our overall market share in Europe and NAFTA

• AHSS share of the total steel market is increasing, exactly where our share is higher

• As the technology requirements to develop and produce new AHSS like Fortiform® are higher, our share on these products can further grow

Capital investments to support existing and new products

Selection of further investments:• $15 million at ArcelorMittal Vega to locally produce Usibor®

• Additional upgrades at AM/NS Calvert to supply the latest AHSS

• €140 million investment at ArcelorMittal Gent to enable production of Fortiform®, our family of 3rd Generation AHSS

• €9 million investment at ArcelorMittal Sagunto to enable production of Usibor® Alusi and increase the group capacity by adapting the hot dip galvanizing line in order to better serve the Southern European automotive market.

• Several investments at AMTB to support the development of Laser Welded Blanks as a mainstream light-weighting solution

Capital investments to fund franchise businessCapital investments to fund franchise business

• This trend should remain progressive and light:

– Carbon fibre not expected to be high relevance before 2030

– Aluminium still too expensive to play a major role

– Steel remains the most recyclable metal (100% recyclable /

environmentally friendly)

– High strength steel to replace mild steel

– New steel material (ultra high strength) has potential to substitute

aluminium parts

Current and future material mix

Steel to remain material of choice with greater share of AHSSSteel to remain material of choice with greater share of AHSS

27

SummaryRegulatory targets and trend towards global platforms created needs for the automotive industry• Continuous improvements to simultaneously meet fuel efficiency and safety

targets• Procure same materials across different regions

ArcelorMittal is investing to deliver responses to these needs• S-in motion® Pickup Truck demonstrated that a body-in-white reduction of

23% can be achieved via our current portfolio of steel products and solutions• Further weight reduction will be achieved with our upcoming steel grades• Enlarging industrial presence with VAMA, AM/NS Calvert and the potential

JV with SAIL in India

ArcelorMittal has products and market position to capture industry growth

Due to an unmatched strength, lightweight potential and global footprint,ArcelorMittal and steel will remain the choice of the automotive industry
