ArcelorMittal CEO Lakshmi N. Mittal Says Quality and Sustainability Are Key for the Future of Steel

Regulatory News:

The steel industry needs to start benchmarking itself against
leading global manufacturing and service companies in order to
activate its long-term potential, Lakshmi Mittal, President and CEO of
ArcelorMittal, said today.

Speaking at the annual Steel Success Strategies Conference in New
York, Mr Mittal said: "I think we are all agreed that today the
industry is in a far healthier position. But similarly I feel that the
new period of stability we have entered calls for a new focus. We have
succeeded in proving that the steel industry has the chance of a
future. Now we have to concentrate on building a steel industry for
the modern age. One which is quality driven in terms of product,
process and supply chain."

Mr Mittal said that whilst the steel industry has been focused on
becoming sustainable for some time, historically this had related to
the ironing out of the industry's cyclicality and volatility. Now, he
said, it is time to work towards a sustainable model focussed on
customer and stakeholder satisfaction, not only self preservation.

"If the past few years have been about ensuring our survival, the
future must be about re-creating an industry admired for its
operational excellence and quality of application and product."

Mr Mittal advised steel companies to work to emulate the strict
quality criteria: "We have to think more like a service company, which
are customer demand led and innovative, rather than supply driven."

Mr Mittal said that steel companies needed to work more closely
with their customer base, implementing a new partnership approach to
ensure they fully understand the benefits the new sustainable model
can bring.

"There are a number of benefits to our customers. It enables us to
continue to invest heavily in R&D and product development. It enables
us to meet the most sophisticated customer demands and improve the
quality of our products. It enables us to offer global solutions with
consistent quality anywhere in the world, whether a developed or
developing market. It enables them to better manage their own input
costs. It enables us to identify new value proposals for them."

Furthermore Mr Mittal underlined the important positive
contribution to sustainable development the industry makes at a
process level but even more importantly thanks to its products, for
instance in the building and construction sector: "Increasing
urbanization requires safe, affordable, aesthetic, sustainable and
rapid construction. Steel is the perfect material for this. It can be
built more quickly. It is 50% lighter than traditional materials. It
is environmentally friendlier, with 80% of steel used in construction
today coming from recycling. Composite construction using steel
creates considerable energy savings and reduces CO2 emissions."

One year after the creation of ArcelorMittal, the undisputed
global steel industry leader, Mr Mittal also provided an update on the
merger.

"Integration is progressing very well and we are making excellent
progress in creating a united culture and operational approach. Our
scale has created an enormous knowledge pool from which all units can
benefit. Operationally we can leverage expertise in more established
markets to our operations in developing ones. Our product and
geographic diversification has created a more stable earnings base.
Our enhanced stability has enabled us to increase our R&D budget to
ensure we produce the most sophisticated products. We are able to
offer customers a global solution with a common standard."
