In recent years we have adapted our footprint to new demand realities, intensified our efforts to control costs and invested in our key franchise businesses. I am happy to report that these considerable efforts are yielding results.

Cautious optimism

Five key strategic enablersA clear licence to operate. Many of our businesses are located in regions in the early stages of economic development. We recognise that we have an obligation to act responsibly towards all stakeholders. Sustainability is one of our core values.

A strong balance sheet. Our balance sheet currently constrains our flexibility for funding organic growth or acquisitions. Achieving the medium-term target for net debt of US$15 billion remains a critical objective.

A decentralised structure. Our scale and scope give us a competitive advantage. They also bring the risk of inefficiency and diffuse accountability. Thus we favour a structure in which the responsibility for profit and loss is focused on business units aligned with markets.

Active portfolio management. We have historically sought to strengthen the business through acquisition. That remains the case. But we are also willing to dispose of businesses that cannot meet our performance standards.

The best talent. Our success will depend on the quality of our people, and our ability to engage, motivate and reward them. We will continue to improve our processes to attract, develop and retain the best talent.

ArcelorMittal’s success is built on its core values of sustainability, quality and leadership. Our strategy is to leverage four distinctive attributes:

• Global scale and scope

• Unmatched technical capabilities

• Diverse portfolio of steel and related businesses, particularly mining

• Financial capability

Three themesSteel. We look to extend our leadership in attractive markets by leveraging our technical capabilities and our global scale. These are critical differentiators for sophisticated customers, such as those in the automotive, energy and infrastructure markets. In addition, we will further develop steel businesses that benefit from favourable market structures or geographies.

Mining. We are working to grow our already world-class mining business by expanding our top-quality assets, by controlling cost and capital expenditure and by producing highly-valued products.

Operations. We strive to achieve best-in-class competitiveness. Operational excellence, including health and safety, is at the core of our strategy. We steadily optimise our asset base and have a commitment to continuous improvement.

Our strategy

Dear shareholders,

In recent years we have adapted our footprint to new demand realities, intensified our efforts to control costs and invested in our key franchise businesses. I am happy to report that these considerable efforts are yielding results.

2013 has been a year of progress. We have made strategic progress, we made progress on profitability and in strengthening the balance sheet.

Our 2013 Ebitda was US$6.9 billion, an underlying improvement of 10.7% compared with 2012. We continue to have a medium term Ebitda per ton target of US$150 and whilst there is still a gap to close, we are moving in the right direction.

Net debt reduction has been a priority and we ended 2013 with US$16.1 billion net debt. Our medium-term net debt target remains at US$15 billion.

We also continue to make progress on health and safety: the lost time injury frequency rate improved again, to 0.8 in 2013 from 1.0 in 2012. This was ahead of our own internal target.

If the period since the onset of the crisis has been marked by adapting to the changed environment and creating a stronger company, now the imperative is to capture the opportunities from a recovery.

Our strategy is to leverage four distinctive attributes that will enable us to capture leading positions in the most attractive areas of the steel industry value chain. These qualities are our global scale and scope; our unmatched technical capabilities; our diverse portfolio of steel and related businesses, particularly mining; and our financial capability.

In 2013, we have continued to focus on the robust implementation of this strategy, and have made significant progress.

In steel, the acquisition of ThyssenKrupp’s rolling mill in Calvert, Alabama, with Nippon Steel & Sumitomo Metal Corporation was a milestone. This is one of the highest quality finishing lines in the world, in a strategic location providing significant opportunity in the growing NAFTA automotive steel and energy markets.

The improvement in the overall economic situation also led us to restart selected steel growth projects. In Brazil, we restarted the first phase of our Monlevade project. In Dofasco, Canada, we restarted our project to expand and upgrade galvanising capacity by 2015.

In mining, we increased capacity by 10 million tonnes in 2013, and we are on track to reach our 2015 capacity target of 84 million tonnes. The big 2013 achievement was the completion of the ArcelorMittal Mines Canada capacity expansion to 24 million tonnes. Our Liberia project is also delivering good results. Phase one shipments increased by over 150% in 2013, ahead of expectations, and phase two is ongoing.

We also continue innovating in our products and processes. In 2013 we unveiled an innovative ultra-lightweight car door, demonstrating that a 27% weight and cost saving is possible, without compromising safety and structural requirements.

In conclusion, I am very satisfied with the progress we are making. The actions we have taken over the past five years are yielding the right results. We have a competitive cost position in each region we serve and we are exposed to the areas with the biggest potential for demand recovery over the next five years. We have identified and are investing in our key franchise businesses. And we are continuing to meet the demands of our customers with the highest quality products.

1 On January 1, 2013, in accordance with IFRS as issued by the International Accounting Standards Board (‘IASB’), ArcelorMittal mandatorily adopted IFRS 10 (‘Consolidated Financial Statements’), IFRS 11 (‘Joint Arrangements’), IFRS 12 (‘Disclosure of Interests in Other Entities’), IFRS 13 (‘Fair Value Measurement’), the revision of IAS 19 (‘Employee Benefits’) and IFRIC 20 (‘Stripping Costs in the Production Phase of a Surface Mine’). Prior period 2012 information has been adjusted retrospectively for the mandatory adoption of these new standards and interpretations except for IFRS 13 which is applied only prospectively. The main effects for ArcelorMittal are related to the revision of IAS 19R which was applied retrospectively. Following the changes, the previously unrecognised actuarial gains and losses on pension liabilities are recorded in the statements of financial position in full against equity. It means that the previously unrecognised actuarial gains and losses are no longer recorded over time against profit and loss following the then allowed ‘corridor approach’. All future actuarial gains and losses will also be immediately recognised in other comprehensive income (OCI). In addition, for purposes of measuring the net financial cost on pension liabilities/assets, the expected rate of return on assets must be equal to the discount rate applicable to liabilities.
