The response set forth in Item 6 of the Statement is hereby amended by deleting the previous disclosure set forth under the heading “Share Repurchase Agreement and Amendments Thereto” in entirety and replacing it with the following:

Share Repurchase Agreement and Amendments Thereto

On February 12, 2021, ArcelorMittal and Lumen entered into a share repurchase agreement (the “Share Repurchase Agreement”) in connection with the First Buy-Back Program and Second Buy-Back Program.

On June 21, 2021, ArcelorMittal and Lumen entered into an amendment to the Share Repurchase Agreement (the “First Amendment Agreement”) in connection with the Third Buy-Back Program.

On July 30, 2021, ArcelorMittal and Lumen entered into a second amendment to the Share Repurchase Agreement (the “Second Amendment Agreement”) in connection with the Fourth Buy-Back Program.

On November 17, 2021, ArcelorMittal and Lumen entered into a third amendment to the Share Repurchase Agreement (the “Third Amendment Agreement”) in connection with the Fifth Buy-Back Program.

On February 15, 2022, ArcelorMittal and Lumen entered into a fourth amendment to the Share Repurchase Agreement (the “Fourth Amendment Agreement”) in connection with the Sixth Buy-Back Program. Under the Fourth Amendment Agreement, on each trading day during which ArcelorMittal conducts purchases under the Sixth Buy-Back Program, ArcelorMittal and Lumen have agreed to buy and sell, respectively, a number of ArcelorMittal Shares, such that the number of ArcelorMittal Shares so purchased and sold represents 36.34% of the sum of: (i) the total number of shares purchased by ArcelorMittal under the Sixth Buy-Back Program (other than from Lumen) and (ii) the number of ArcelorMittal Shares purchased by ArcelorMittal from Lumen pursuant to the Fourth Amendment Agreement, in each case on that trading day. Except as specifically provided for and varied by the Fourth Amendment Agreement, all of the terms and conditions of the Share Repurchase Agreement will remain in full force and effect. Accordingly, consistent with the Share Repurchase Agreement, the ArcelorMittal Shares to be repurchased from Lumen in connection with the Sixth Buy-Back Program during any trading day will be repurchased at the same weighted average price as the ArcelorMittal Shares purchased under the Sixth Buy-Back Program on the relevant trading day in the open market. Purchases and sales occurring during periods of five consecutive trading days will be settled together two trading days following the end of each such period. However, any settlement of ArcelorMittal Shares in connection with the Sixth Buy-Back Program will be postponed if such settlement would cause the Trustee to hold less than one-third of all the voting rights of ArcelorMittal (including those connected with the ArcelorMittal Shares held in treasury by or on behalf of ArcelorMittal or the subsidiaries of ArcelorMittal).

The foregoing summary of the Share Repurchase Agreement, the First Amendment Agreement, the Second Amendment Agreement, the Third Amendment Agreement and the Fourth Amendment Agreement are qualified by references to the full text of the Share Repurchase Agreement, the First Amendment Agreement, the Second Amendment Agreement, the Third Amendment Agreement and the Fourth Amendment Agreement, copies of which are included as Exhibit 8, Exhibit 9, Exhibit 10, Exhibit 11 and Exhibit 12, respectively, to this Seventeenth Amendment and which are incorporated herein by reference.

The response set forth in Item 6 of the Statement is hereby amended by deleting the previous disclosure set forth under the heading “Articles of Association of Grandel” in entirety and replacing it with the following:

Articles of Association of Grandel Singapore

As per the articles of association of Grandel Singapore, the non-voting Class B shares of Grandel Singapore entitle the holders thereof to economic rights in Grandel Singapore, with limited voting rights. Currently the Class B shares are held directly or indirectly by a series of four trusts, the beneficiaries of which are Mr. and Mrs. Mittal and/or certain of their family members. The holders of the Class B shares of Grandel Singapore would receive any dividends or distributions paid by Grandel Singapore in accordance with the dividend policies implemented in the organizational documents of Grandel Singapore and its subsidiaries, which dividends or distributions may include the pass-through of dividends paid by ArcelorMittal to Lumen and Nuavam or proceeds of the sales by such entities of ArcelorMittal Shares. The limited voting rights of holders of Class B shares include the right to appoint two representatives, who have a consent right with respect to the granting of certain liens over any interest held in Grandel Singapore’s subsidiaries and/or ArcelorMittal.

The foregoing summary of the terms of the Articles of Incorporation of Grandel Singapore is qualified in its entirety by reference to the full text of the Articles of Incorporation of Grandel Singapore, a copy of which is included as Exhibit 5 to this Statement and is incorporated herein by reference.

To the knowledge of the Reporting Persons, except as specified in this Statement, there are no other contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 or between the persons named in Item 2 and any person with respect to any securities of ArcelorMittal, including but not limited to transfer or voting of any of the securities of ArcelorMittal, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies, or a pledge or contingency the occurrence of which would give another person voting power or investment power over the securities of ArcelorMittal.

Lumen Investments S.à r.l. and ArcelorMittal – February 2022]

FOURTH AMENDMENT TO THE SHARE REPURCHASE AGREEMENT (the “Amendment Agreement”) dated 15 February 2022 by and between:

(1) Lumen Investments S.à r.l., a limited liability company (société à responsabilité limitée), incorporated and existing under the laws of the Grand Duchy of Luxembourg, with registered office at 6, rue Eugène Ruppert, L-2453 Luxembourg, Grand Duchy of Luxembourg, and registered with the Luxembourg Register of Commerce and Companies under number B152.437 (the “Seller”); and

(2) ArcelorMittal, a Luxembourg société anonyme incorporated and existing under the laws of the Grand Duchy of Luxembourg, having its registered office at 24-26, Boulevard d’Avranches, L-1160 Luxembourg, Grand Duchy of Luxembourg, and registered with the Luxembourg Register of Commerce and Companies under number B82.454 (the “Purchaser” and, together with the Seller, the “Parties”).

RECITALS:

(A) The Purchaser announced on 15 February 2021 a Share buy-back program for an aggregate maximum amount of six hundred and fifty (650) million U.S. Dollars (the “First BB Program”). The Purchaser also announced that upon the completion of the First BB Program, it will commence a further Share buy-back program for an aggregate amount of five hundred and seventy (570) million U.S. Dollars (the “Second BB Program”). The Purchaser announced on 18 June 2021 a Share buy-back program for an aggregate maximum amount of seven hundred and fifty (750) million U.S. Dollars (the “Third BB Program”).

The Purchaser announced on 11 November 2021 and 17 November 2021 a Share buy-back program for an aggregate maximum amount of one billion (1,000,000,000) U.S. Dollars (the “Fifth BB Program”).

(B) In the context of the Program (as defined below), the Seller wishes to maintain the Significant Shareholder’s holding of the Purchaser’s issued and outstanding Shares (net of treasury Shares) (and voting rights) at its current level of 36.34 percent. The Seller therefore intends to sell in the Program an equivalent variable number of Shares, at the proportion of Significant Shareholder’s current stake of 36.34 percent of issued and outstanding Shares of the Purchaser, in accordance with the terms and conditions set forth herein.

(C) The Parties propose to amend the share repurchase agreement dated 12 February 2021 (as amended on 21 June 2021, 30 July 2021 and 17 November 2021) (the “Agreement”) by entering into this further Amendment Agreement for the purpose of the repurchase from time to time by the Purchaser of Shares from the Seller under the Program.
