Record Voter Participation Demonstrates Shareholder Engagement

Southern Copper's 2026 Annual Meeting of Stockholders achieved exceptionally high voter turnout, with 804,192,988 shares cast in favor of various proposals. This voting total represented approximately 97.35% of the 826,065,041 total outstanding voting securities eligible to participate in the meeting, indicating substantial investor engagement with the company's governance matters. Such elevated participation rates provide company leadership with a clear mandate from shareholders on key organizational decisions.

The strong quorum reflects confidence in the company's governance structure and strategic direction. High voter participation is particularly significant for a multinational copper producer with operations spanning multiple jurisdictions, as it suggests that both institutional and retail investors view the company's annual meeting as an important opportunity to weigh in on organizational leadership and compensation policies. This level of engagement can strengthen the company's credibility with both current and prospective investors.

Director Elections Proceed With Overwhelming Approval

All eight nominated director candidates received substantial affirmative votes from stockholders at the May 29, 2026 meeting. Vicente Ariztegui Andreve received the highest vote count at 787,452,909 shares in favor, with only 1,632,820 shares withheld. Jose Pedro Valenzuela Rionda received the second-highest support with 788,083,538 shares voting in favor and 1,002,191 withheld. The consistent approval margins across all eight candidates suggest shareholder satisfaction with the board's composition and individual member performance.

Each of the eight elected directors will serve until the 2027 annual meeting of stockholders. The board composition includes Germán Larrea Mota-Velasco, Leonardo Contreras Lerdo de Tejada, Vicente Ariztegui Andreve, Javier Arrigunaga Gomez del Campo, Enrique Castillo Sánchez Mejorada, Luis Miguel Palomino Bonilla, Carlos Ruiz Sacristán, and Jose Pedro Valenzuela Rionda. All eight candidates secured the support of more than 761 million shares, with withhold votes representing a small fraction of total voting power in each case.

Independent Audit Firm Ratification Achieves Near-Unanimous Support

Stockholders ratified the Audit Committee's selection of Galaz, Yamazaki, Ruiz Urquiza S.C., a member firm of Deloitte Touche Tohmatsu Limited, as the company's independent accountants for calendar year 2026. The vote on this proposal showed overwhelming support, with 803,321,862 votes cast in favor, 751,278 against, and 119,848 abstentions. The audit firm ratification garnered approximately 99.9% affirmative voting support, among the highest approval margins of any proposal at the meeting.

The appointment of a major audit firm is a critical governance function that ensures the company's financial reporting meets regulatory standards and maintains investor confidence. Galaz, Yamazaki, Ruiz Urquiza S.C.'s affiliation with Deloitte Touche Tohmatsu Limited, one of the world's largest professional services networks, indicates that Southern Copper maintains access to substantial audit resources and expertise. The near-unanimous stockholder endorsement of this selection underscores investor confidence in the audit process and the company's financial controls.

Executive Compensation Receives Strong Advisory Endorsement

Southern Copper's executive compensation program received approval through a non-binding advisory vote, with 785,220,671 shares voting in favor, 3,578,467 votes cast against, and 286,591 shares abstaining. Broker non-votes totaled 15,107,259 shares. The affirmative votes constituted approximately 99.5% of voted shares, indicating strong stockholder support for the company's approach to executive pay and incentive structures. This result provides management with confidence that the compensation committee's decisions align with investor expectations.

Although the vote is non-binding, it serves as an important barometer of shareholder sentiment regarding how the company rewards senior leadership. The overwhelming approval suggests that stockholders view the executive compensation structure as appropriately balanced between performance incentives and shareholder value protection. The company disclosed no information in the filing regarding specific compensation amounts, changes to incentive structures, or management responses to investor feedback on pay policies.

Meeting Logistics and Participation Summary

The May 29, 2026 annual meeting presented stockholders with three distinct proposals for their consideration. Each proposal received individual voting treatment, allowing shareholders to express differentiated preferences on matters ranging from board composition to audit oversight to executive remuneration. The disclosure of broker non-votes separately from withheld votes provides transparency regarding the mechanics of share voting and the extent of shareholder discretion exercised by beneficial owners.

The meeting achieved its purpose of securing stockholder authorization for fundamental governance matters, with all three proposals receiving affirmative votes from the majority of shares voted. The consistent participation rate across all three proposals—with approximately 97% of eligible shares voting on each matter—demonstrates that shareholders approached the entire ballot with equal attention and engagement rather than selectively focusing on particular items.

Broker Non-Votes and Voting Mechanics

The disclosure of broker non-votes in the director elections and executive compensation vote provides insight into how many beneficial shares were held in street name at the meeting. Broker non-votes totaled 15,107,259 shares for both the director election and the executive compensation proposals. These shares were held by brokers and custodians who did not receive voting instructions from the beneficial owners, and therefore were not counted as votes for or against the respective proposals under New York Stock Exchange rules.

The presence of significant broker non-votes—representing approximately 1.9% of total outstanding shares—indicates that a portion of Southern Copper's shareholder base did not exercise active voting authority on particular matters. However, the overall voting participation rate remained exceptionally high despite these non-votes, suggesting that most beneficial owners either provided voting instructions to their brokers or held shares directly and participated in the vote directly.

Compliance and Governance Framework

Southern Copper's disclosure of the annual meeting results demonstrates adherence to Securities Exchange Act requirements for reporting stockholder votes on matters of corporate governance and executive compensation. The company filed this report on July 17, 2026, providing timely public notice of the stockholder meeting outcomes. The detailed tabulation of voting results for each director candidate and each proposal offers transparency regarding the level of support each item received and the distribution of withheld and dissenting votes.

The company's incorporation in Delaware and listing on the New York Stock Exchange subjects it to both state corporate law standards and federal securities regulations governing disclosure and governance practices. The filing indicates that Southern Copper maintains dual listing on the Lima Stock Exchange as well, reflecting its multinational operational footprint and shareholder base. Compliance with these multiple regulatory frameworks requires robust governance infrastructure and disclosure protocols.

Implications for Shareholder Relations and Governance

The exceptionally high voting participation and overwhelming approval margins for all three proposals indicate a stable relationship between Southern Copper's management and its investor base. The election of all eight directors without significant opposition, combined with strong support for the audit firm and executive compensation, suggests that shareholders view the company's strategic direction and governance practices as aligned with investor interests. This consensus provides management with a clear mandate to continue current strategic initiatives without the distraction of governance disputes.

The filing does not disclose details regarding specific shareholder proposals submitted by investors, activist engagement, or contentious governance debates that may have preceded the meeting. The absence of significant withheld votes for any director candidate—with the highest withhold count at approximately 3.1% of total shares voted—suggests that Southern Copper's board maintains investor confidence in its individual members' qualifications and contributions to company oversight. The company did not disclose any information regarding potential future governance changes or anticipated shareholder concerns in this filing.

Forward Governance Calendar and Next Steps

The election results establish that all eight board members will serve until the company's next annual meeting of stockholders in 2027. The ratification of Galaz, Yamazaki, Ruiz Urquiza S.C. as independent auditors for calendar year 2026 authorizes the company to proceed with its financial reporting and audit processes under their engagement. The non-binding approval of executive compensation does not require specific management action but provides guidance regarding shareholder expectations for pay policies going forward.

Southern Copper did not disclose in this filing any planned changes to board composition, modifications to the audit firm engagement, adjustments to executive compensation policies, or other governance initiatives anticipated for the coming year. Investors interested in tracking changes to the company's governance structure or leadership team should monitor future filings and official company announcements for details regarding any such modifications or transitions.
