ARCELORMITTAL REPORTS FULL YEAR AND FOURTH QUARTER 2010 RESULTS

Luxembourg, February 8, 2011 - ArcelorMittal (referred to as “ArcelorMittal” or the “Company”) (MT (New York, Amsterdam, Paris, Brussels, Luxembourg), MTS (Madrid)), the world’s leading steel company, today announced results1 for the three and twelve month periods ended December 31, 2010.

Successful spin-off of stainless steel business (Aperam) following shareholders’ approval on January 25, 2011. Accordingly, stainless steel results for 4Q 2010 are recorded as discontinued operations, and prior results and operational KPI’s have been recast to reflect the new presentation2.

Highlights:
·	Health and Safety frequency rate3 improved in 2010 to 1.8x as compared to 1.9x in 2009; marked improvement in 4Q 2010 with rate at 1.6x compared with 1.9x for 3Q 2010.
·	Full year EBITDA4 of $8.5 billion (excluding $0.4 billion for Aperam), 52% higher than 2009; full-year net income of $2.9 billion or $1.93 per share.
·	4Q 2010 EBITDA of $1.9 billion (including $0.1 billion from sale of CO2 credits); Q4 2010 net loss of $0.8 billion (or $0.51 loss per share) primarily due to impairment associated with the stainless demerger.
·	Shipments of 85.0 Mt in 2010, 22% higher than 2009; 4Q 2010 shipments of 21.1 Mt up 3% vs. 3Q 2010.
·	Strong cash flow from continuing operations of $3.3 billion in 4Q 2010 ($3.8 billion for 2010) led to a $2.3 billion reduction in net debt5 to $19.7 billion as of December 31, 2010, as compared to $22.1 billion as of September 30,  2010.
·	Own iron ore production of 48.9 Mt in 2010 as compared to 37.7 Mt in 2009; 12.6 Mt in 4Q 2010.
·	Successful spin-off of stainless steel business (Aperam) following shareholders’ approval on January 25, 2011.
·	ArcelorMittal has along with Nunavut Iron Ore jointly acquired more than 90% of Baffinland Iron Mines Corporation; the Company’s immediate focus will be on completing the project feasibility studies.

Outlook and guidance:
·	Volumes are expected to increase in 1Q 2011 as the gradual underlying demand recovery continues and market sentiment improves.  Additionally, selling prices are adjusting to rapid increases in raw material prices.
·	Q1 2011 EBITDA expected to be between $2.0 - $2.5 billion
·	Q1 2011 capacity utilisation expected to rise to ~76% (vs. 69% in Q4 2010); working capital requirements and net debt expected to increase accordingly (the latter sharply)
·	2011 CAPEX budget of $5 billion of which $1.4 billion for mining
·	2011 target of ~10% increase in our own iron ore production as compared to 2010

Commenting, Mr. Lakshmi N. Mittal, Chairman and CEO, ArcelorMittal, said:

“Although 2010 continued to be a challenging year, as anticipated we saw a slow and progressive recovery which enabled us to deliver a substantially improved performance compared with 2009. The gradual underlying demand recovery continues and we expect 2011 to be stronger than 2010.

The year has started positively with the successful spin-off of Aperam.  We have also continued to pursue expansion in mining and have recently acquired control of Baffinland, an extremely high-quality iron-ore asset in Canada.”

Key initiatives for the three months ended December 31, 2010

ArcelorMittal announces the launch of its Responsible Sourcing program

·   ArcelorMittal’s substantial supply chain footprint provides unique opportunities for promoting sustainable business practices.  In order to formalize this, ArcelorMittal has launched a responsible sourcing program, which incorporates health and safety, human rights, and ethical and environmental principles into ArcelorMittal's procurement approach. The first phase of communicating the Code for Responsible Sourcing to the company’s key global suppliers is underway, as well as a pilot to incorporate this into the annual supplier evaluation process.

ArcelorMittal unveiled the results of its “S-in motion” automotive research program

·   Developed through direct technical collaboration with leading automotive manufacturers, the S-in motion portfolio comprises a range of over 60 innovative Press-Hardened Steel (PHS) and Advanced High-Strength Steel (AHSS) solutions that can be implemented in vehicles today, delivering direct benefits to both car makers and consumers in terms of weight, safety and efficiency.

Analysis of results for the twelve months ended December 31, 2010 versus results for the twelve months ended December 31, 2009

ArcelorMittal’s net income for the twelve months ended December 31, 2010 was $2.9 billion, or $1.93 per share, as compared to net income for the twelve months ended December 31, 2009 of $0.2 billion, or $0.11 per share.

Total steel shipments for the twelve months ended December 31, 2010 increased by 22% to 85.0 million metric tonnes as compared with 69.6 million metric tonnes for the twelve months ended December 31, 2009.

Sales for the twelve months ended December 31, 2010 were $78.0 billion, as compared with sales for the twelve months ended December 31, 2009 of $61.0 billion. The increase was due to the improvement in global steel markets in the wake of the global economic crisis, leading to margin recovery and higher steel shipments.

Depreciation costs for the twelve months ended December 31, 2010 were $4.4 billion as compared with depreciation costs of $4.6 billion for the twelve months ended December 31, 2009.

Impairment losses for the twelve months ended December 31, 2010 amounted to $525 million and included $305 million relating to the Company’s coal mines in Russia, (including the disposal of the Anzherskaya mine), $113 million relating to several subsidiaries in the Distribution Solutions segment (primarily reflecting continued construction market weakness), and $107 million primarily relating to idle downstream assets in the European business. Impairment losses for the twelve months ended December 31, 2009 were $552 million.6

Operating income for the twelve months ended December 31, 2010 was $3.6 billion, as compared with an operating loss7 of $1.5 billion for the twelve months ended December 31, 2009. Operating performance for the twelve months ended December 31, 2010 was positively impacted by a net gain of $140 million recorded on the sale of carbon dioxide credits, the proceeds of which will be re-invested in energy saving projects, and by non-cash gains of $354 million relating to unwinding of hedges on raw material purchases. Operating performance for the twelve months ended December 31, 2009 had been negatively impacted by an exceptional charge of $2.4 billi on (pre-tax) related primarily to write down on inventory and provisions for workforce reductions. This was partly offset by an exceptional gain of $380 million relating to a reversal of litigation provisions, a net gain of $108 million recorded on the sale of carbon dioxide credits, which was re-invested in energy saving projects and a non-cash gain of $979 million relating to unwinding of hedges on raw material purchases.

Income from equity method investments and other income for the twelve months ended December 31, 2010 was $451 million, as compared to $56 million for the twelve months ended December 31, 2009. The increase was due primarily to improvement in the underlying operations and results of the Company’s equity investments as a result of better economic conditions in 2010.

Net interest expense (including interest expense and interest income) was $1.4 billion for the twelve months ended December 31, 2010 as compared to $1.5 billion for the twelve months ended December 31, 2009. Interest cost decreased during the year in line with lower average net debt.

During the twelve months ended December 31, 2010, the Company also recorded a non-cash gain of $427 million primarily as a result of mark-to-market adjustments on the conversion options embedded in its euro and dollar-denominated convertible bonds issued in 20098. During the twelve months ended December 31, 2009, the Company recorded a non-cash loss of $897 million attributable to these adjustments. On December 14, 2010 and December 18, 2010, respectively, the Company acquired 61.7 million euro-denominated call options and 26.5 million dollar-denominated call options on its own shares in order to hedge its obligations under these convertible bonds. As a result, no additional mark-to-market gains or losses on the embedded derivatives in the convertible bonds are expected going forward.

Foreign exchange and other net financing costs9 were $1.2 billion for the twelve months ended December 31, 2010, as compared to $0.5 billion for the twelve months ended December 31, 2009. In 2010 the Company recorded foreign exchange losses of $0.3 billion primarily on monetary assets held in foreign currencies compared to a gain of $0.5 billion in 2009.

Page 5 of 23

Income tax benefit for the twelve months ended December 31, 2010 amounted to $1.5 billion, as compared to an income tax benefit for the twelve months ended December 31, 2009 of $4.4 billion. The lower income tax benefit for the year was primarily due to ArcelorMittal’s 2010 profit as compared with its 2009 pre-tax loss.

Income attributable to non-controlling interest for the twelve months ended December 31, 2010 amounted to $89 million as compared with losses attributable to non-controlling interest for the twelve months ended December 31, 2009 of $43 million. This change results from higher income in subsidiaries with non-controlling interest following the underlying improvement of market conditions in 2010.

The discontinued operations line2 comprises exclusively the post-tax net results contributed by the stainless steel business now known as Aperam which was spun-off from ArcelorMittal on January 25, 2011. For the twelve months ended on December 31, 2010 this amounted to losses of $330 million. On a stand alone basis Aperam is reporting a net profit of $104 million for the twelve months ended on December 31, 2010. The reconciling items are as follows:

· (-) Recognition by ArcelorMittal of non-cash impairment charge of $598 million following the reclassification of the stainless segment as a discontinued operation. As required by IFRS (IFRS 5), and upon reclassification of the business as assets held for distribution, the assets and liabilities must be carried at the lower of their carrying amount and fair value less costs to distribute (the amount is lower than initially anticipated in the press release published on December 8, 2010 as a result of updated valuations).

· (+) Elimination by ArcelorMittal of $120 million of interest charges on intra group loans and other intra group transactions between the stainless segment and other group companies. Discontinued operations in ArcelorMittal statements of operations are reported after full elimination of intra group transactions between the stainless segment and other group companies. Other adjustments account for $44 million. In Aperam stand alone statement of operations transactions with ArcelorMittal are not eliminated.

Analysis of results for the three months ended December 31, 2010 versus the three months ended September 30, 2010 and the three months ended December 31, 2009

ArcelorMittal recorded a net loss for the three months ended December 31, 2010 of $0.8 billion, or $0.51 loss per share, as compared with net income of $1.4 billion, or $0.89 per share, for the three months ended September 30, 2010, and net income of $1.1 billion,or $0.73 per share, for the three months ended December 31, 2009.

Total steel shipments for the three months ended December 31, 2010 were 21.1 million metric tonnes as compared with 20.5 million metric tonnes for the three months ended September 30, 2010, and 19.5 million metric tonnes for the three months ended December 31, 2009.

Sales for the three months ended December 31, 2010 increased 4.8% to $20.7 billion as compared with $19.7 billion for the three months ended September 30, 2010, and were up 18.7% as compared with $17.4 billion for the three months ended December 31, 2009.  Sales were higher during the fourth quarter of 2010 as compared to the third quarter of 2010 primarily due to higher shipment volumes (+3%).

Depreciation expense of $1.1 billion for the three months ended December 31, 2010 was flat as compared to the three months ended September 30, 2010 and slightly down from $1.2 billion for the three months ended December 31, 2009.

Impairment losses for the three months ended December 31, 2010 was $381 million, and included $186 million relating to the Company’s coal mines in Russia, $113 million relating to certain subsidiaries in the Distribution Solutions segment (primarily reflecting continued construction market weakness) and $82 million primarily relating to idle downstream assets in the European business. Impairment cost for the three months ended September 30, 2010 was $26 million relating to impairment of a pickling line in Liege, Belgium. Impairment losses for the three months ended December 31, 2009 had amounted to $488 million10.

Page 6 of 23

Operating income for the three months ended December 31, 2010 was $0.4 billion, as compared with operating income of $1.0 billion for the three months ended September 30, 2010 and operating income of $0.7 billion for the three months ended December 31, 2009. The drop in operating income resulted from higher operating costs, primarily due to a rise in raw materials cost, while steel selling prices were generally lower for the quarter.

In addition, operating performance for the three months ended December 31, 2010 included a non-cash gain of $88 million relating to unwinding of hedges on raw material purchases as compared to an $82 million gain recorded in the three months ended September 30, 2010.  Fourth quarter 2010 operating performance was also positively impacted by a net gain of $140 million recorded on the sale of carbon dioxide, the proceeds of which will be re-invested in energy saving projects. Operating performance for the three months ended December 31, 2009 had been positively impacted by an exceptional gain of $380 million relating to a reversal of litigation provisions and a net gain of $108 million recorded on the sale of carbon di oxide credits the proceeds of which were re-invested in energy saving projects.

Income from equity method investments and other income for the three months ended December 31, 2010 was $74 million, as compared to $107 million and $100 million for the three months ended September 30, 2010 and December 31, 2009, respectively.

Net interest expense (including interest expense and interest income) increased to $413 million for the three months ended December 31, 2010 from $376 million for the three months ended September 30, 2010, primarily due to the impact of exchange rate fluctuations and higher interest on account of new bonds issued. Net interest expense for the three months ended December 31, 2009 was $413 million.

During the three months ended December 31, 2010, the Company also recorded a non-cash loss of $293 million, as compared to a $24 million non-cash gain in the third quarter of 2010 and a $430 million non-cash loss for the three months ended December 31, 2009, as a result of mark-to-market adjustments relating to its convertible bonds issued in 2009. As a result of the December 2010 dilution management hedging transactions, no additional mark-to-market gains or losses on the embedded derivatives in the convertible bonds are expected going forward.

Foreign exchange and other net financing costs were $494 million for the three months ended December 31, 2010 as compared to $31 million for the three months ended September 30, 2010. During the three months ended December 31, 2010 a 2.1% appreciation of the USD resulted in a foreign exchange loss of $0.1 billion on deferred tax assets of approximately €4.0 billion as compared to a foreign exchange gain of $0.5 billion in the three months ended September 30, 2010 when the USD depreciated by 11.47%. Foreign exchange and other net financing costs for the three months ended December 31, 2009 had amounted to $70 million.

ArcelorMittal recorded an income tax benefit of $450 million for the three months ended December 31, 2010, as compared to an income tax benefit of $576 million for the three months ended September 30, 2010. The income tax benefit for the three months ended December 31, 2009 was $1.2 billion.

The discontinued operations line2 comprises exclusively the post-tax net results contributed by the stainless steel business now known as Aperam which was spun-off from ArcelorMittal on January 25, 2011. For the three months ended on December 31, 2010 this amounted to losses of $547 million.

The increase was due to increased slab deliveries from our South American and Mexican operations. Brazilian domestic shipments were lower as local producers were impacted by continued de-stocking by distributors and lower priced imports.

Sales in the Flat Carbon Americas segment were $5.0 billion for the three months ended December 31, 2010, an increase of 4.9% as compared to $4.8 billion for the three months ended September 30, 2010. Sales increased primarily due to higher steel shipments (+9.1%) partly offset by lower average steel selling prices (-6.9%).

EBITDA in the fourth quarter declined to $541 million, 29.8% lower than in the previous quarter. The decrease was driven primarily by lower steel selling prices, whilst the contribution from mining operations remained stable quarter on quarter.

Flat Carbon Europe crude steel production amounted to 7.0 million tonnes for the three months ended December 31, 2010, a decline of 1.4% as compared to 7.1 million tonnes for the three months ended September 30, 2010.
 

Shipments for the three months ended December 31, 2010 were 6.6 million tonnes, a slight increase of 1.1% as compared to 6.5 million tonnes for the three months ended September 30, 2010.

Sales in the Flat Carbon Europe segment were $6.8 billion for the three months ended December 31, 2010 an increase of 8.8% as compared to $6.3 billion for the three months ended September 30, 2010. Sales increased primarily due to the appreciation of the euro against the US dollar (as the average euro/US dollar exchange rate rose 5% from 1.29 in the third quarter to 1.36 in the fourth quarter), which contributed to higher average selling prices in US dollar terms, as well as marginally higher steel shipments.

EBITDA for the three months ended December 31, 2010 was $563 million, an 18.3% increase as compared to $476 million for the three months ended September 30, 2010. EBITDA in the fourth quarter was positively impacted by a $140 million gain on sale of carbon dioxide credits that ArcelorMittal will fully re-invest in energy savings project within the Flat Carbon Europe perimeter.  Excluding this gain, EBITDA in the fourth quarter 2010 was down 11.1% to $423 million due to higher costs.

Operating results in the fourth quarter of 2010 were positively impacted by an $88 million non-cash gain relating to the unwinding of hedges on raw material purchases and the gain of $140 million recorded on the sale of carbon dioxide credits referred to above, which were partly offset by a $37 million charge primarily relating to idle downstream assets. Operating results in the third quarter of 2010 had included a $26 million charge relating to impairment of a pickling line in Liege, Belgium, and a $82 million non-cash gain relating to hedges on raw material purchases.

Long Carbon Americas and Europe crude steel production reached 5.3 million tonnes for the three months ended December 31, 2010, a decrease of 2.7% as compared to 5.5 million tonnes for the three months ended September 30, 2010 due mainly to a seasonal slowdown in Brazil.

Shipments for the three months ended December 31, 2010 were 5.7 million tonnes, a slight decline of 1.3% as compared to 5.8 million tonnes for the three months ended September 30, 2010, primarily due to the seasonal slowdown in the South American operations.

Page 10 of 23

Sales in the Long Carbon Americas and Europe segment were $5.6 billion for the three months ended December 31, 2010, essentially flat as compared to $5.5 billion for the three months ended September 30, 2010. Overall average steel selling prices remained stable in US Dollar terms quarter on quarter, but declined in local currency.

EBITDA for the three months ended December 31, 2010 was $343 million, a 45.8% decline as compared to $633 million for the three months ended September 30, 2010. The decrease was primarily due to Long Carbon Americas which had a seasonal reduction in volumes, reduced production resulting in higher fixed costs as well as an overall reduction in prices in local currency. In Long Carbon Europe lower steel selling prices in local currency also contributed to a decline in EBITDA. The third quarter of 2010 EBITDA included $67 million relating to income associated with the revaluation of the Bioenergia forestry assets.

AACIS segment crude steel production was 3.6 million tonnes for the three months ended December 31, 2010, a decrease of 3.1% as compared to 3.7 million tonnes for the three months ended September 30, 2010, due primarily to lower production in the South African operations.

Shipments for the three months ended December 31, 2010 were 3.4 million tonnes, an increase of 4% as compared to 3.3 million tonnes for the three months ended September 30, 2010, due to higher exports from both the CIS and South African operations.

Sales in the AACIS segment remained flat at $2.6 billion for the three months ended December 31, 2010 and for the three months ended September 30, 2010. Average steel selling prices in the fourth quarter were slightly lower in US dollar terms, which was offset by slightly higher shipments.

EBITDA for the three months ended December 31, 2010 was $281 million, 21.9% lower as compared to $360 million for the three months ended September 30, 2010. EBITDA in the South African operations declined dramatically during the fourth quarter of 2010 primarily due to production disruptions and weakness in the domestic market. EBITDA in the CIS operations improved during the fourth quarter of 2010 as compared to the third quarter of 2010, due to higher shipments and selling prices.

EBITDA for the three months December 31, 2010 was $87 million, 31% lower as compared to $126 million for the three months ended September 30, 2010 due to lower selling prices in local currency and higher costs.  EBITDA and operating results in the fourth quarter of 2010 had been negatively impacted by a $113 million charge relating to impairment on certain subsidiaries, primarily reflecting continued construction market weakness.

Stainless Steel (Discontinued operations)12

The successful spin-off of the stainless steel business took place following shareholders’ approval on January 25, 2011. Accordingly, results of the stainless steel operations in Q4 2010 have been presented as discontinued operations.

Page 12 of 23

During the fourth quarter of 2010 the Company sold 37.98 million of treasury shares for total proceeds of $1.4 billion. The proceeds were used to fund the purchase of call options to purchase 88.2 million ArcelorMittal shares. As disclosed in the press releases of December 14, 2010 and December 27, 2010, the acquired call options allow the Company to hedge its obligations under its 7.25% and 5.0% bonds convertible into and/or exchangeable for new or existing ArcelorMittal shares due April 1, 2014 and May 15, 2014, respectively.

During the fourth quarter of 2010, the Company paid dividends amounting to $335 million as compared to $331 million in the third quarter of 2010. Dividends paid during the fourth quarter of 2010 include $282 million to the parent company shareholders and $53 million paid to minority shareholders in subsidiaries.

At December 31, 2010, the Company’s cash and cash equivalents (including restricted cash and short-term investments) amounted to $6.3 billion as compared to $3.5 billion at September 30, 2010. During the quarter, net debt decreased by $2.3 billion to $19.7 billion as compared with $22.1 billion at September 30, 2010.

The Company had liquidity of $17.614 billion at December 31, 2010, compared with liquidity of $14.9 billion at September 30, 2010, consisting of cash and cash equivalents (including restricted cash and short-term investments) of $6.3 billion and $11.3 billion of available credit lines.

In connection with the spin-off of Aperam to the Company's shareholders, ArcelorMittal has provided a $900 million one-year bridge loan put in place in order to ensure that the Aperam transaction was credit neutral for ArcelorMittal.  Following the effectiveness of the spin-off, the bridge loan is recorded as a receivable from Aperam. Aperam is currently in talks with banks regarding new financings, the proceeds of which would be used to repay the bridge loan.

Dividend maintained at $0.75 per share for 2011

The Board of Directors will submit to a shareholders’ vote, at the next annual general meeting, a proposal to maintain the quarterly dividend payment at $0.1875 per share. The dividend payments would occur on a quarterly basis for the full year 2011, on March 14, 2011, June 14, 2011, September 12, 2011 and December 12, 2011, taking into account that the first quarter dividend payment to be paid on March 14, 2011 shall be an interim dividend.

Final payment of current year dividend of $0.1875 per share was made on December 15, 2010. 

Update on management gains, fixed cost reduction program and capacity utilization

At the end of the fourth quarter of 2010, the Company’s annualized sustainable savings increased to $3.2 billion as compared to $2.9 billion at the end of September 30, 2010.

First quarter of 2011 outlook

First quarter 2011 EBITDA is expected to be approximately $2.0 - $2.5 billion. Shipment volumes, average steel selling prices and EBITDA/tonne are expected to increase as compared to the fourth quarter of 2010, while capacity utilization levels are expected to improve to approximately 76%.  Additionally, operating costs are expected to increase as compared to the fourth quarter of 2010 due to higher raw material prices.

The Company expects working capital requirements and net debt to increase in the first quarter 2011 in line with the increased activity levels, higher raw material costs and increased investment activity (including M&A). The Company expects its full year 2011 capex spend to reach $5 billion, of which $1.4 billion is estimated to be spent on mining.

Appendix 7 – End notes

______________________________________________

1 The financial information in this press release has been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). While the interim financial information included in this announcement has been prepared in accordance with IFRS applicable to interim periods, this announcement does not contain sufficient information to constitute an interim financial report as defined in International Accounting Standards 34, “Interim Financial Reporting”. Unless otherwise noted the numbers in the press release have not been audited. The financial information and certain other information presented in a number of tables in this press release have been rounded to the nearest whole number or the nearest decimal. Therefore, the sum of the numbers in a column may not conform exactly to the total figure given for that column. In addition, certain percentages presented in the tables in this press release reflect calculations based upon the underlying information prior to rounding and, accordingly, may not conform exactly to the percentages that would be derived if the relevant calculations were based upon the rounded numbers.

2 Following the approvals by ArcelorMittal’s board and shareholders’ meetings held on December 7, 2010 and January 25, 2011, respectively, to spin off the stainless steel business into a separately focused company Aperam, the results of the Company’s stainless steel operations are shown as discontinued operations in accordance with International Financial Reporting Standard (IFRS) 5 “Non-current Assets Held for Sale and Discontinued Operations”. ArcelorMittal’s financial disclosures with respect to the Aperam spin off in this press release are as follows:

   Statements of Financial Position

·   As of December 31, 2010 all assets related to Aperam entities (current and non-current) are reclassified and disclosed separately in a single line item as “Assets Held for Distribution” (current assets). Likewise, all liabilities are reclassified and disclosed separately in a singe line item as “Liabilities Held for Distribution” (current liabilities).

·   Upon reclassification certain assets must be carried at the lower of their carrying amount and fair value less costs to sell. ArcelorMittal reported a write-down of approximately $0.6 billion (the amount is lower than initially anticipated in the press release published on December 8, 2010 as a result of updated valuations)

·   Prior years in the Statements of Financial Position are not subject to changes in presentation as they are not required to be recast under IFRS.

Statements of Operations

·   The Statements of Operations are recast into continuing and discontinued operations. Net post-tax results of discontinued operations are presented in a single line item as “Discontinued Operations”. Additional information detailing discontinued operations will be provided in the footnotes of future earnings releases and the Company’s 2010 annual report.

·   Earnings per Share (“EPS”) are presented for continuing and discontinued operations and for total net results – see appendix 6.

·   Prior years and quarters presented in this press release (3Q10, 4Q09 and 2009FY) are recast following the same principles.

Statements of Cash Flows

·   The Statements of Cash Flows are recast into continuing and discontinued operations. Contributions from discontinued operations are presented in three separate lines: “Net cash provided by (used in) operating activities -- Discontinued operations”, “Cash used in investing activities -- Discontinued operations” and “Net cash (used in) provided by financing activities --Discontinued operations”.

·   Prior years and quarters presented in this press release (3Q10, 4Q09 and 2009FY) are recast following the same principles.

Key Performance Indicators (KPI)

·   Prior period KPI analyses, including EBITDA,  presented in this press release (3Q10, 4Q09 and 2009FY) have been recast to exclude the contributions of Aperam entities

·   Guidance for first quarter of 2011 does not include Aperam.

3 Lost time injury frequency rate equals lost time injuries per 1,000,000 worked hours, based on own personnel and contractors.

4 EBITDA is defined as operating income plus depreciation, impairment expenses and exceptional items.

5 Net debt refers to long-term debt, plus short term debt, less cash and cash equivalents, restricted cash and short-term investments. 

6 Impairment costs for the twelve months ended December 31, 2009 consisted primarily of $237 million of impairment for various idled assets (including $92 million relating to the impairment of coke oven assets at Galati, Romania and $65 million at Las Truchas, Mexico), $122 million of impairment for various tubular product operations (primarily $65 million in Roman, Romania), and $172 million of other impairments (including $117 million at ArcelorMittal Construction France).

7During 2009 the Company recorded an exceptional gain of $380 million relating to reversal of litigation costs previously booked in the fourth quarter of 2008 following the Paris Court of Appeals decision to reduce the fine imposed on certain French distribution subsidiaries of ArcelorMittal by the French Competition Authority from €302 million ($441 million) to €42 million ($61 million). This gain was offset by exceptional charges amounting to $2.4 billion pre-tax related primarily to write-downs of inventory ($2.1 billion) and provisions for workforce reduction ($0.3 billion).

8 On April 1, 2009 and May 6, 2009, the Company issued approximately $2.5 billion of bonds which are convertible into its shares at the option of the bondholders. Under the terms of its €1.25 billion euro-denominated convertible bonds due 2014 (OCEANEs), the Company has the option to settle the bonds for shares or for an amount equivalent to the cash value of the shares at the date of the settlement (this cash settlement option was waived in October 2009, with respect to the Company’s $800 million US dollar–denominated convertible bonds due 2014). . The Company has determined that the convertible bonds are hybrid instruments as defined by IFRS and has identified certain components of the contracts to be embedded derivatives in accordance with IAS 39.  At each reportin g period (until, with respect to the USD bonds, the waiver noted above) changes in the fair value of the embedded derivatives (recorded at $597 million at inception) have been recorded to the statement of operations, resulting in gains or losses depending on marking to market. As a result of the hedging transactions undertaken in December 2010 (see “Recent Developments”), no additional mark-to-market gains or losses are expected going forward.

9 Foreign exchange and other net financing costs include foreign currency swaps, bank fees, interest on pensions, impairments of financial instruments and revaluation of derivative instruments

10 Impairment costs for the three months ended December 31, 2009 of $488 million consisted of $169 million on various idled assets (primarily $65 million at Las Truchas, Mexico), $122 million on various tubular product operations (primarily $65 million in Roman, Romania), and $172 million on other impairment assets (primarily $117 million at ArcelorMittal Construction France).

11 As from January 1, 2010 the Steel Solutions and Services segment has been renamed ArcelorMittal Distribution Solutions (AMDS).

12 The financial information presented for stainless steel operations in ArcelorMittal books may differ from Aperam books, as in ArcelorMittal the discontinued operations are presented on a contributive approach. As a result all inter-company transactions with Aperam continue to be fully eliminated and the portion reported as part of discontinued operations and assets/liabilities held for distribution include only the contribution of Aperam to ArcelorMittal after elimination of intersegment results. Additionally there are differences on account of impairment, goodwill and others.

13 Rotation days are defined as days of accounts receivable plus days of inventory minus days of accounts payable. Days of accounts payable and inventory are a function of cost of goods sold. Days of accounts receivable are a function of sales.

14 Includes back-up lines for the commercial paper program of approximately $2.7 billion (€2 billion).

15 Total of all finished production of fines, concentrate, pellets and lumps (includes share of production and strategic long-term contracts).

16 ArcelorMittal Distribution Solutions shipments are eliminated in consolidation as they primarily represent shipments originating from other ArcelorMittal operating subsidiaries

17 In accordance with IFRS the Company has adjusted the 2009 financial information retrospectively for the finalization in 2010 of the allocation of purchase price for certain business combinations carried out in 2009. The adjustments have been reflected in the Company’s consolidated financial statements for the year ended December 31, 2009.

18 Changes in operating working capital are defined as trade accounts receivable plus inventories less trade accounts payable.

19 Segmental capex includes the acquisition of intangible assets (such as concessions for mining and IT support).

20 Average steel selling prices are calculated as steel sales divided by steel shipments.

21Shipments originating from a geographical location.

22 Includes Tubular products business

23$422.5 million US bond due 2014 redeemed early on April 1, 2010 in line with the terms of the indenture.

24Commercial paper is expected to continue to be rolled over in the normal course of business.

25 Euro denominated loans converted at the Euro: $ exchange rate of 1.3362 as at December 31, 2010.

26 Gearing is defined as (A) long-term debt, plus short-term debt, less cash and cash equivalents, restricted cash and short-term investments, divided by (B) total equity.
