Facing the challenges

Our strategic prioritiesHealth and safety remains our number one priority in all sites and at all levels of the business. Our Journey to Zero programme to reduce workplace accidents and occupational diseases has delivered five consecutive years of progress. Beyond our relentless focus on health and safety, we have a number of key strategic priorities, which are part of a defined roadmap to improve profitability and return on capital:

Optimised operating footprintIn line with reduced levels of demand, we have focussed on our operating footprint. This enables us to satisfy customer requirements more efficiently through the use of our most competitive assets.

Cost efficiencyOur four-year plan to reach US$4.8 billion of management gains was achieved ahead of schedule. Looking ahead, we have identified a further US$3 billion cost optimisation programme to be achieved by the end of 2015.

Strong balance sheetWith our balance sheet repositioned, we are focussed on meeting our medium-term net debt target of US$15 billion, and in an excellent position to manage upcoming debt maturities.

Protect and leverage franchise businessesWe are concentrating our investments to protect and expand our franchise businesses in attractive markets where we have a competitive edge, such as automotive, mining and Brazil.

Maximised mining resourcesWe continue to invest in our core growth projects in Canada and Liberia. We are leveraging our existing infrastructure to develop new iron ore capacity at incrementally lower cost.

ArcelorMittal has a three-dimensional model that aims to reduce risk and deliver sustainability and growth:

Geographical breadth – we are the leading steel producer in the Americas, Europe and Africa and a top-four producer in the CIS.

Product diversity – we are leaders in automotive steel and we meet the needs of all key customer segments, encompassing a broad range of products to cater for developed and developing economies.

Raw materials security – we are one of the world’s largest iron ore producers, having expanded iron ore production by around 50% since 2009. We are on track to expand our capacity by a further 50% by 2015.

Our strategy

Dear shareholders,

2012 was another very challenging year for the steel industry. The priority for ArcelorMittal was to adapt our business to meet those challenges. Before I go into detail on the progress we have made, I would first like to update you on our health and safety results. We continue to make progress, with our lost time injury frequency rate improving significantly from 1.4 in 2011 to 1.0 in 2012. We had set ourselves a target of 1 by 2013 so to reach it a year early was a good achievement. Zero accidents remain our ultimate goal.

As I mentioned, last year was a difficult year. Indeed, because of the convergence of a number of well-documented factors, it was the most challenging year we have experienced since 2009.The biggest single impact on our performance was the further deterioration of the European economy.

We have been consistently adapting our business to the new economic environment since the onset of the crisis. But in 2012 we took further steps to respond to two main issues: production overcapacity and debt.

The successful capital raise announced at the start of this year, combined with other measures, has taken us a significant way towards meeting our medium-term net debt target of US$15 billion.

The closures or proposed closures we have made to shut down uncompetitive assets, mostly in Europe, will yield a more efficient footprint and have a positive impact on our business.

Having addressed our weaknesses, we are now better able to focus on our strengths, for example on what we call our franchise businesses. These are businesses in attractive markets where the company has a competitive edge, such as automotive, sheet piles, mechanical tubing and wide and heavy hot-rolled for high-strength applications. The steels we are producing and developing in these businesses are cutting edge and we will prioritise investment here to ensure they grow and expand.

Outside steel, mining is another important franchise business. We have been steadily growing iron ore shipments since 2008 and in 2012 made significant progress, in particular at ArcelorMittal Mining Canada which is on track to ramp up from 16 to 24 million tonnes of production capacity during the first half of 2013.

Looking forward, although 2013 will continue to be challenging, we believe that the second half of 2012 will prove to have been the bottom of the cycle. The global outlook for economic growth is gradually improving, with a modest upturn expected through 2013, leading to stronger growth in 2014. In particular, the situation in the US and many emerging economies is positive.

We are therefore cautiously optimistic and expect global steel demand to increase by around 3 - 3.5% this year. As you would expect, we continue to maintain a rigorous focus on cost and we have recently announced a new management gains target of US$3 billion, to be achieved by the end of 2015.

In conclusion, I want to say that whilst 2012 was a very difficult year, we have addressed the main challenges facing us. As a result we are in a stronger position, ready to provide excellent steel solutions to our customers. Steel remains very relevant to the world we live in. Every day, our steel is being used in unique and diverse ways: from a solar energy project in the Indian Ocean to the largest infrastructure project in Europe. Steel really is – as we say at ArcelorMittal - the fabric of modern life.

Finally, we have moved our full annual review to www.arcelormittal.com for the first time this year, to enable a more user-friendly experience. I hope you take the time to visit the website, and that you will like it.
