Southern Copper Director Castillo Sanchez Mejorada Acquires 400 Shares Through Stock Award Plan

Director Equity Award Granted Through Stock Compensation Plan

The disclosure filed by Southern Copper Corporation shows that director Enrique Castillo Sanchez Mejorada received 400 shares of common stock on July 24, 2026. The company statement indicates that these shares were received pursuant to the issuer's Directors' Stock Award Plan, which represents a standard compensation mechanism for board members. The transaction was executed as an exempt transaction under Rule 16b-3(d) of the Securities Exchange Act of 1934, confirming that this type of director equity grant falls within regulatory safe harbors designed for routine corporate compensation arrangements.

Director stock award plans are common governance tools used by publicly traded companies to align board member interests with shareholder value. By providing equity compensation to directors, corporations encourage long-term focus on company performance and demonstrate confidence in their organization. The filing does not disclose the specific dollar value or price per share at which these shares were granted, though the transaction code indicates an acquisition without a stated exercise or conversion price, consistent with unrestricted stock grants.

Beneficial Ownership Position Following the Acquisition

Following the July 24, 2026 transaction, Enrique Castillo Sanchez Mejorada's total beneficial ownership of Southern Copper common stock reached 1,400 shares, held in direct form of ownership. This figure represents the cumulative effect of the 400-share acquisition disclosed in the current filing. The disclosure explicitly identifies the ownership as direct beneficial ownership, meaning the director holds legal title to the shares personally rather than through any intermediary or indirect arrangement.

The beneficial ownership disclosure is significant for investors monitoring insider positions at the company. Direct share ownership by board members can signal their confidence in Southern Copper's business prospects and strategic direction. The filing provides no indication of whether the director intends to hold, sell, or further acquire shares in the near term, nor does it contain any restrictions on the director's ability to trade these securities outside of standard blackout periods and insider trading rules.

Reporting Person's Role and Relationship to Southern Copper

The disclosure identifies Enrique Castillo Sanchez Mejorada as a director of Southern Copper Corporation, as indicated by the "Director" box checked in the relationship section of the filing. The reporting person is associated with the company's principal offices located at 7310 North 16th Street, Suite 135, in Phoenix, Arizona. The filing does not indicate that the director holds any officer title or other executive position at the company beyond board membership, nor does it identify the individual as a ten-percent owner of Southern Copper common stock.

Director appointments and equity holdings are subject to public disclosure requirements under Section 16(a) of the Securities Exchange Act of 1934. These requirements ensure transparency regarding the ownership stakes of corporate insiders and allow investors to monitor whether board members maintain meaningful financial stakes in the companies they oversee. The timing and content of this disclosure was executed in compliance with SEC reporting deadlines, with the transaction occurring on July 24, 2026, and the statement filed four days later on July 28, 2026.

Rule 16b-3(d) Exempt Transaction Classification

The filing specifically notes that the 400-share acquisition was received pursuant to a transaction intended to satisfy the affirmative defense conditions of Rule 16b-3(d). This SEC rule provision creates an exemption from short-swing profit recapture rules for certain equity grants to directors and officers. By qualifying under Rule 16b-3(d), the transaction avoids the restriction that would normally require insiders to return profits from purchases and sales of company securities occurring within a six-month window. This classification reflects regulatory recognition that director stock awards are compensation transactions, not speculative trades.

The exemption under Rule 16b-3(d) applies specifically to equity awards granted under a plan approved by shareholders or the board of directors, provided that the award's terms were fixed at the time of plan adoption or were approved in advance by the compensation committee. The fact that Southern Copper's Directors' Stock Award Plan is explicitly referenced in the filing suggests the plan maintains the necessary compliance structure to support such exemptions. This regulatory framework enables companies to incentivize director service through equity grants without exposing directors to the short-swing profit liability that would apply to discretionary securities purchases.

No Derivative Securities or Options Disclosed

The filing contains no entries in Table II, which is designated for reporting derivative securities such as options, warrants, puts, calls, or convertible securities. This absence indicates that the transaction disclosed involves only common equity shares and does not include any derivative securities arrangements. The straightforward nature of the award as a direct common stock grant, rather than an options grant or other derivative instrument, suggests a simple equity compensation structure without embedded exercise prices, expiration dates, or conversion mechanics.

Many director compensation programs offer a mix of common stock grants and option awards. The absence of any derivative component in this particular grant filing may reflect the specific terms of Southern Copper's Directors' Stock Award Plan or may indicate that options or other derivatives were granted at a separate time. Investors reviewing director holdings should note that this disclosure addresses only common shares and derivative instruments are tracked separately on corporate beneficial ownership reports.

Timing of Transaction and Filing Compliance

The transaction was executed on July 24, 2026, and the formal disclosure was filed with the Securities and Exchange Commission on July 28, 2026, representing a four-day lag between execution and reporting. SEC rules require Form 4 statements to be filed within two business days of the transaction date in most cases, though certain provisions allow for extended timelines under specified circumstances. The filing was executed by attorney-in-fact Andres C. Ferrero on behalf of the reporting person, a common practice in corporate insider reporting that allows designated professionals to prepare and submit disclosure documents.

The timely filing of this disclosure demonstrates Southern Copper's compliance with Section 16 reporting obligations. Investors relying on insider trading disclosures to monitor corporate leadership decisions should note that Form 4 filings become publicly available through the SEC's EDGAR database shortly after submission. The July 28 filing date means this information entered public markets at the close of the trading week, allowing investors and analysts to incorporate the insider transaction data into their market analysis.

Southern Copper Common Stock Transaction Details

The securities involved in this transaction are common shares of Southern Copper Corporation, identified by the NYSE ticker symbol SCCO. The filing indicates that 400 shares were acquired, coded as an "A" (acquisition) transaction type. No price per share is disclosed in the filing, which is consistent with equity awards under employee and director stock plans where the consideration is service rather than a cash payment. The acquisition is recorded as a direct transaction, with the shares registered in the director's name without any intermediary or indirect holding arrangement.

Common stock acquisitions by directors through equity award plans typically carry no specific exercise price or conversion premium, distinguishing them from option-based awards. The lack of pricing information in the filing reflects the nature of stock grants as non-derivative awards. Investors seeking historical context on the value of these grants at the time of award may reference Southern Copper's publicly traded share price on July 24, 2026, though such valuation context is not provided within the SEC disclosure itself.

Insider Reporting Requirements and Transparency

The disclosure of insider transactions by Southern Copper's board members serves an important investor protection function under federal securities law. Section 16 of the Securities Exchange Act requires officers, directors, and ten-percent shareholders to file reports of their transactions in company securities. These filings create a public record of insider activity that allows investors and market participants to assess whether corporate leadership is accumulating or divesting shares, which may provide indirect signals about management confidence in the company's prospects. The requirement applies regardless of transaction size, ensuring comprehensive disclosure even for routine equity awards.

Investors monitoring insider trading activity should understand that routine director compensation grants like this one reflect standard governance practices rather than discretionary trading decisions. Nevertheless, aggregating such data over time can reveal patterns in director shareholding and provide context for evaluating board member alignment with shareholder interests. The SEC's EDGAR database and various third-party financial information platforms aggregate these filings to enable investors to track insider positions and transactions systematically.

Future Monitoring and Investor Considerations

The disclosure of this equity award does not provide information regarding future transactions or additional share grants that may be made to this director. Investors interested in monitoring ongoing equity compensation to Southern Copper's board should expect additional Form 4 filings if further awards are granted or if the director engages in any sales of shares held. The cumulative beneficial ownership of 1,400 shares established by this disclosure provides a baseline for tracking future changes to the director's position in the company.

Shareholders considering the composition and incentive alignment of Southern Copper's board of directors may use these ownership disclosures as one data point among many. The quantum of shares held by each board member, relative to their overall compensation and personal net worth, can provide insight into the strength of their financial alignment with long-term shareholder value. However, the single transaction disclosed in this filing should not be interpreted as providing comprehensive information about the director's total compensation, equity grants over time, or overall investment thesis regarding Southern Copper's business.
