EXPLANATORY NOTE

Southern Copper Corporation (the "Registrant") is filing this Post-Effective Amendment No. 5 to the Registration Statement on Form S-8, File No. 333-150982, filed with the Securities and Exchange Commission (the “Commission”) on May 16, 2008 (the "Original Registration Statement"), for the sole purpose of disclosing the three-year extension of the Directors’ Stock Award Plan (“Plan”) to January 27, 2031 and the increase in the number of shares to be awarded to each non-employee director of 200 shares contingent upon such director’s attendance at all Board meetings. In accordance with the requirements of Form S-8 under the Securities Act of 1933, as amended (the “Securities Act”) we registered 128,000 shares of the common stock, par value $0.01 per share, of Southern Copper Corporation (the “Company,” “SCC,” “we,” “us” or “our”) to be issued under the Plan, a stockholder approved plan. The Original Registration Statement also covered any additional shares of common stock which became issuable under the Plan registered pursuant to the Original Registration Statement by reason of any stock dividend, stock split, recapitalization or any other similar transaction effected without the receipt of consideration which resulted in an increase in the number of the Registrant’s outstanding shares of common stock. The Plan previously provided that directors who are not compensated as employees of the Company will be automatically awarded 1,200 shares of common stock upon election and 1,200 additional shares following each annual meeting of stockholders thereafter. The Plan originally expired by its terms on January 31, 2016. On January 28, 2016, the Board of Directors of the Company (“Board”) approved, subject to stockholder approval, a one-year extension of the Plan. On January 26, 2017, the Board approved another one-year extension of the Plan, subject to stockholder approval. Such Plan extensions were approved at the Annual Meetings of Stockholders of 2016 and 2017, respectively. On January 25, 2018, the Board approved a further extension of the Plan for five years and an amendment to the Plan to increase the number of shares to be granted to non-employee directors from 1,200 to 1,600. At the 2018 Annual Meeting of Stockholders the amendments to increase the award amount from 1,200 to 1,600 and the five-year extension of the Plan until January 28, 2023, were approved. On April 22, 2021, the Board amended the Directors’ compensation, so that commencing with the second quarter 2021, eligible directors are granted 400 Shares quarterly, conditioned upon the attendance of such directors at each quarterly Board meeting. On January 27, 2022, the Board of Directors approved, subject to stockholder approval, a further five-year extension of the Plan. At the 2022 Annual Meeting of Stockholders held May 27, 2022, the stockholders approved a five-year extension of the Plan until January 27, 2028. On March 6, 2025 the Board approved a further extension of the Plan for three years and an amendment granting 200 Shares to each eligible director, contingent upon attendance of such director at all quarterly Board meetings. At the 2025 Annual Meeting of Stockholders held May 23, 2025, the stockholders approved a three-year extension of the Plan until January 27, 2031 and the amendment to provide 200 shares to the eligible directors annually, contingent upon their attendance at all Board meetings. As of August 4, 2025, 454,000 shares had been awarded under the Plan, leaving 146,000 shares available for use after that date.

Item 6.   Indemnification of Directors and Officers.

Section 102(b)(7) of the Delaware General Corporation Law, or DGCL, enables a corporation in its certificate of incorporation or an amendment thereto, to eliminate or limit the personal liability of a director to the corporation or its stockholders for monetary damages for violation of the director’s fiduciary duty, except (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL (providing for liability of directors for unlawful payment of dividends or unlawful stock purchases or redemptions) or (iv) for any transaction from which a director derived an improper personal benefit. Our amended and restated certificate of incorporation, as amended, provides for such limitations on liability for its directors to the fullest extent permitted by Delaware law.

Section 145 of the DGCL provides that a corporation may indemnify any person who is or was a director, officer, employee or agent of a corporation against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of being or having been in any such capacity, if he acted in good faith in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action, or proceeding, had no reasonable cause to believe his conduct was unlawful, except that with respect to an action brought by or in the right of the corporation, such indemnification is limited to expenses (including attorneys fees) and court approval is required before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. Section 145 of the DGCL provides that it is not exclusive of other indemnification that may be granted by a corporation’s charter, by-laws, disinterested director vote, stockholder vote, agreement or otherwise. Our amended and restated certificate of incorporation and our by-laws, as amended, provide that the Company must indemnify its directors and officers to the fullest extent permitted by Delaware law and as provided in our by-laws.

Our by-laws provide indemnification rights to any of our officers or directors who, by reason of the fact that he or she is one of our officers or directors, is involved in a legal proceeding of any nature if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. Such indemnification rights will include reimbursement for expenses incurred by such officer or director in advance of the final disposition of such proceeding in accordance with the applicable provisions of Delaware law. Our by-laws provide that we may arrange for insurance covering such liabilities and expenses arising from actions or omissions of a director or officer in his or her capacity as a corporate agent as is obtainable and is reasonable and appropriate in cost and amount. The Company currently maintains liability insurance for its directors and officers.
