ArcelorMittal Announces Cash Tender Offer to Purchase Any and All of Its USD 5.375% Notes Due 2013

Regulatory News:

ArcelorMittal (“ArcelorMittal”) today announced the commencement of an offer (the “Offer”) to purchase for cash any and all of its notes (the “Notes”) of the series set forth in the table below. The Notes have an aggregate principal amount outstanding of US$1,500,000,000.

ArcelorMittal is making the Offer in order to retire all or a portion of the Notes prior to their maturity.

(1) Per US$1,000 principal amount of Notes accepted for purchase. ArcelorMittal will also pay accrued and unpaid interest from, and including, the last interest payment date for the Notes to, but not including, the Settlement Date (as defined below).

The Offer is being made pursuant to an Offer to Purchase dated February 23, 2012 (the “Offer to Purchase,” as it may be amended or supplemented from time to time) which sets forth in more detail the terms and conditions of the Offer.

The Offer will expire at 5:00 p.m., New York City time, on March 1, 2012, unless extended or earlier terminated (such date and time, as they may be extended or earlier terminated, the “Expiration Time”). Any Notes purchased pursuant to the Offer will be paid for in same-day funds on the third business day following the date of tender, or as soon thereafter as practicable (such payment date, the “Settlement Date” for such tender).

The Offer is not contingent upon the tender of any minimum principal amount of Notes.

ArcelorMittal is making a concurrent bond offering, consisting of three-year, five-year and ten-year notes. The proceeds from such bond financing are expected to provide sufficient financing for the purchase of the Notes as described above, plus costs and expenses related to the Offer. If the total amount owed in connection with the Offer exceeds the net proceeds of the concurrent bond financing, ArcelorMittal will fund this excess with internally generated funds.

ArcelorMittal has retained J.P. Morgan Securities LLC to serve as the dealer manager for the Offer. D.F. King & Co., Inc. has been retained to serve as the information agent.

None of ArcelorMittal, the dealer manager or the information agent makes any recommendation as to whether any holder of the Notes should tender or refrain from tendering all or any portion of the principal amount of the Notes.
