EX-99.1

ARCELORMITTAL ANNOUNCES RETIREMENT OF
MR MALAY MUKHERJEE FROM EXECUTIVE ROLE

- WILL JOIN THE BOARD OF DIRECTORS EFFECTIVE 13^th MAY*

Luxembourg, [7^th] April 2008 - ArcelorMittal today announces the retirement of Mr Malay Mukherjee, Member of the Group Management Board with responsibility for Asia, Africa, CIS, Mining, Stainless and Pipes & Tubes. Mr Mukherjee, 60, will retire from his executive duties on 13^th May, the date of the Company’s Annual General Meeting.

The Board of Directors will propose to the Annual General Meeting of Shareholders that he will be appointed a non executive member of the Company's Board of Directors effective from that date

Mr Mukherjee joined ArcelorMittal (then Ispat International) on 1^st January 1993 as Executive Director of the company’s Mexican operations, where he subsequently became CEO. Following his tenure in Mexico, he then moved to Kazakhstan in 1996 where he spent three years as the company’s CEO. He left Kazakhstan in 1999 to become President and CEO of Ispat Europe. Then in 2001 he was appointed Chief Operating Officer, first of Ispat International and subsequently of Mittal Steel Company, following the merger between Ispat International, LNM Holdings and International Steel Group to create the world’s largest steel company. Following the merger in 2006 between Arcelor and Mittal Steel, Mr Mukherjee was appointed as one of the six members of the company’s Group Management Board, with particular responsibility for Asia, Africa, the CIS, Mining, Stainless and Pipes and Tubes. Prior to joining ArcelorMittal, he spent many years with the Steel Authority of India Limited (SAIL), where his last position was as Executive Director (Works) at the Bhilai Steel Plant, the largest integrated steel plant in India.

Commenting, Mr Mukherjee said, “It has been a real privilege to have spent the last 15 years of my career working for ArcelorMittal. When I joined the company it was producing 1.3 million tons of steel. Today it is not only the leading steel company, but the company that has transformed the fortunes of the industry through driving a new approach and business model. When I first met Mr Mittal his drive and commitment was obvious, but I could not have imagined that the impact of this would be so substantial

or extensive. I feel honoured to have enjoyed a ring-side seat in what has been an exhilarating, challenging and enormously rewarding journey, working so closely with such an exceptionally talented and motivated leader. Even though I am now taking a step back from the day-to-day operations of the company, I am delighted to have been asked to become a Member of the Company’s Board of Directors. I have no doubt that the ArcelorMittal journey has only just begun and that the company will continue to go from strength to strength.

Mr Mittal said, “I am very sad to be announcing Malay’s retirement from the executive board of ArcelorMittal. He has been an exceptional colleague over the years, someone with deep operational experience, impeccable judgement and great professional integrity. His counsel has been invaluable and he has played a very considerable role in helping ArcelorMittal become the leading steel company that it is today. On behalf of all my colleagues who have worked extensively with Malay, we are very sorry to see him go. However I am very pleased that our collaboration will continue on the Board of Directors, where I have no doubt Malay’s views will be invaluable in the company’s next stage of development.”

Mr Kinsch, Chairman of the Board of Directors, said, “On behalf of all the Members of the Board of Directors, I would like to thank Mr Mukherjee for his contribution to ArcelorMittal. As a member of the Group Management Board, he has played a very important role in the development of our company, particularly in the critical post-integration merger phase. I am delighted that, subject to shareholder approval, we will be welcoming Mr Mukherjee to the Board. He is one of the most experienced executives in the steel industry today and his presence will certainly further strengthen our Board.”

*Subject to Shareholder Approval at the Annual General Meeting to be held on 13^th May.
