#### ABOUT THIS PROSPECTUS
This prospectus is part of an automatic shelf registration statement that we filed with the SEC, as a "well-known seasoned issuer" as defined in Rule 405 under the Securities Act of 1933, as amended, or the Securities Act. By using an automatic shelf registration statement, we may, at any time and from time to time, offer and sell the securities described in this prospectus in one or more offerings.

This prospectus only provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a supplement to this prospectus that will contain specific information about the terms of that offering, including the specific amounts, prices and terms of the securities offered. The prospectus supplement may also add, update or change information contained in this prospectus. You should carefully read both this prospectus and any applicable prospectus supplement or other offering materials, together with the additional information described under the headings "Where You Can Find More Information" and "Documents Incorporated by Reference."

We may also prepare free writing prospectuses that describe particular securities. Any free writing prospectus should also be read in connection with this prospectus and with any applicable prospectus supplement referred to in that free writing prospectus. For purposes of this prospectus, any reference to a prospectus supplement may also refer to a free writing prospectus unless the context requires otherwise.

We have not authorized anyone to provide any information other than that contained or incorporated by reference in this prospectus or in any free writing prospectus prepared by or on behalf of us or to which we have referred you. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We are not making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted.

This prospectus and any applicable prospectus supplement or other offering materials do not contain all of the information included in the registration statement as permitted by the rules and regulations of the SEC. We are subject to the informational requirements of the Exchange Act, and, therefore, file reports and other information with the SEC. Statements contained in this prospectus and any applicable prospectus supplement or other offering materials about the provisions or contents of any agreement or other document are only summaries. If SEC rules require that any agreement or document be filed as an exhibit to the registration statement, you should refer to that agreement or document for its complete contents.

You should not assume that the information in this prospectus, any applicable prospectus supplement or any other offering materials is accurate as of any date other than the date on the front of each document. Our business, financial condition, results of operations and prospects may have changed since then.

In this prospectus, unless otherwise specified or the context requires otherwise, we use the terms "Southern Copper," "Southern Copper Corporation," "SCC," the "Company," "we," "us" and "our" to refer to Southern Copper Corporation and its subsidiaries, collectively.

#### SUMMARY INFORMATION
*This is only a summary and may not contain all the information that is important to you. You should carefully read both this prospectus and any applicable prospectus supplement and any other offering materials, together with the additional information described under the heading "Where You Can Find More Information" and "Documents Incorporated by Reference."* 

#### SOUTHERN COPPER CORPORATION

#### General Information
We believe we are one of the largest integrated copper producers in the world. Our major production includes copper, molybdenum, zinc and silver. All of our mining, smelting and refining facilities are located in Peru and Mexico, and we conduct exploration activities in those countries and in Argentina and Chile. The considerable scale of our operations makes us one of the largest mining companies in Peru and Mexico. We believe we have the largest copper reserves in the world. We were incorporated in Delaware in 1952 and have conducted copper mining operations since 1960. Since 1996, our common stock has been listed on both the New York and the Lima Stock Exchanges pursuant to local applicable Peruvian regulations.

Our Peruvian copper operations involve mining, milling and flotation of copper ore to produce copper; the smelting of copper concentrates to produce blister and anode copper; and the refining of anode copper to produce copper cathodes. As part of this production process, we also produce significant amounts of molybdenum concentrate and sulfuric acid. Our precious metals plant at the Ilo refinery produces refined silver, gold, and other materials. Additionally, we produce refined copper using solvent extraction/electrowinning technology ("SX-EW"). We operate the Toquepala and Cuajone open-pit mines high in the Andes Mountains, approximately 860 kilometers southeast of the city of Lima, Peru. We also operate a smelter and refinery west of the Toquepala and Cuajone mines in the coastal city of Ilo, Peru.

Our Mexican operations are conducted through our subsidiary, Minera México, S.A. de C.V. ("Minera Mexico"), which we acquired in 2005. Minera Mexico engages primarily in the mining and processing of copper, molybdenum, zinc, silver, gold and lead. Minera Mexico operates through subsidiaries that are grouped into three separate units. Mexicana de Cobre, S.A. de C.V. (together with its subsidiaries), operates La Caridad, an open-pit copper mine, the Pilares open-pit copper mine, a copper ore concentrator, a SX-EW plant, a smelter, a refinery and a rod plant. The La Caridad refinery has a precious metals plant that produces refined silver, gold and other materials. Operadora de Minas e Instalaciones Mineras, S.A. de C.V., operates Buenavista, an open-pit copper mine, which is located on the site of one of the world's largest copper ore deposits, two copper concentrators, a zinc concentrator and two operating SX-EW plants. Industrial Minera México, S.A. de C.V. (together with its subsidiaries), operates five underground mines that produce zinc, lead, copper, silver and gold, and a zinc refinery.

We utilize modern, state of the art mining and processing methods, including global positioning systems and computerized mining processes. Our operations have a high level of vertical integration, which allows us to use our facilities, employees and equipment to manage the entire production process, including ore mining and production of refined copper, rod and other products, and to execute most associated transport and logistics functions.

The sales prices for our products are largely determined by market forces beyond our control. Our management, therefore, focuses on cost control and production enhancement to remain profitable. We endeavor to achieve these goals through capital spending programs, exploration efforts and cost reduction programs. Our focus is on remaining profitable during periods of low copper prices and maximizing results in periods of high copper prices.

Our principal executive offices are located at 7310 North 16th St, Suite 135, Phoenix, Arizona 85020, USA and our telephone number at that address is (602) 264-1375. Our corporate website is www.southerncoppercorp.com. This URL is intended to be an inactive textual reference only. It is not intended to be an active hyperlink to our website. The information included in our website or which may be accessed through our website is not part of this prospectus, is not incorporated by reference herein or otherwise and should not be relied upon in determining whether to make an investment in any securities.

#### RISK FACTORS
Investing in our securities involves risks. You should carefully read and consider the risks described under the section entitled "Risk Factors" in our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q, which are incorporated by reference herein, as well as the other information contained in or incorporated by reference into this prospectus and in any applicable prospectus supplement, before making a decision to invest in our securities. Each of the risks described in these documents could materially and adversely affect our business, financial condition, results of operations and prospects, and could result in a partial or complete loss of your investment.

#### **TABLE OF CONTENTS**

#### CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
This prospectus, any applicable prospectus supplement and the documents incorporated by reference herein contain certain forward-looking statements within the meaning of Section 21E of the Exchange Act and Section 27A of the Securities Act. Statements that do not relate strictly to historical or current facts are forward-looking and usually identified by the use of words such as "anticipate," "estimate," "forecasts," "approximate," "expect," "project," "intend," "plan," "believe," "will," "may" and other words of similar meaning in connection with any discussion of future operating or financial matters. Such statements are made in reliance upon the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.

Without limiting the generality of the foregoing, forward-looking statements in this prospectus, any applicable prospectus supplement and the documents incorporated by reference herein include statements regarding expected commencement dates of mining or metal production operations, projected quantities of future metal production, anticipated production rates, operating efficiencies, costs and expenditures, including taxes, as well as projected demand or supply for the Company's products. Actual results could differ materially based upon many factors, including, among others, the risks and uncertainties relating to general U.S. and international economic and political conditions, the cyclical and volatile prices of copper, other commodities and supplies, including fuel and electricity, availability of materials, insurance coverage, equipment, required permits or approvals and financing, the occurrence of unusual weather or operating conditions, lower than expected ore grades, water and geological problems, the failure of equipment or processes to operate in accordance with specifications, failure to obtain financial assurance to meet closure and remediation obligations, labor relations, litigation and environmental risks, political and economic risk associated with foreign operations as well as changes in applicable law and enhanced environmental, mining and tax regulation. Results of operations are directly affected by metals prices on commodity exchanges, which can be volatile. Forward-looking statements speak only as of the date on which they are made. We expressly disclaim any obligation or undertaking to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. These statements involve risks and uncertainties that could cause actual results to differ materially from projected results. Accordingly, investors should not place undue reliance on forward-looking statements as a prediction of actual results. We have based these forward-looking statements on current expectations and assumptions about future events. While we consider these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks and uncertainties, most of which are difficult to predict and many of which are beyond our control. The risks and uncertainties that may affect our operations, performance and results and the forward-looking statements include, but are not limited to, those set forth under Item 1A, "Risk Factors" commencing on page 16 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, as supplemented by the risk factors included in Item 1A of our Form 10-Q filed with the SEC on April 30, 2026.

#### PLAN OF DISTRIBUTION
We may sell the securities offered by this prospectus from time to time in one or more transactions, including without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;• directly to one or more purchasers;

&nbsp;&nbsp;&nbsp;&nbsp;• through agents;

&nbsp;&nbsp;&nbsp;&nbsp;• to or through underwriters, brokers or dealers;

&nbsp;&nbsp;&nbsp;&nbsp;• through a combination of any of these methods.

A distribution of the securities offered by this prospectus may also be effected through the issuance of derivative securities, including without limitation, warrants, subscriptions, exchangeable securities, forward delivery contracts and the writing of options.

In addition, the manner in which we may sell some or all of the securities covered by this prospectus includes, without limitation, through:

&nbsp;&nbsp;&nbsp;&nbsp;• a block trade in which a broker-dealer will attempt to sell as agent, but may position or resell a portion of the block, as principal, in order to facilitate the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;• purchases by a broker-dealer, as principal, and resale by the broker-dealer for its account;

&nbsp;&nbsp;&nbsp;&nbsp;• ordinary brokerage transactions and transactions in which a broker solicits purchasers; or

&nbsp;&nbsp;&nbsp;&nbsp;• privately negotiated transactions.

We may also enter into hedging transactions. For example, we may:

&nbsp;&nbsp;&nbsp;&nbsp;• enter into transactions with a broker-dealer or affiliate thereof in connection with which such broker-dealer or affiliate will engage in short sales of the common stock pursuant to this prospectus, in which case such broker-dealer or affiliate may use shares of common stock received from us to close out its short positions;

&nbsp;&nbsp;&nbsp;&nbsp;• sell securities short and redeliver such securities to close out our short positions;

&nbsp;&nbsp;&nbsp;&nbsp;• enter into option or other types of transactions that require us to deliver common stock to a broker-dealer or an affiliate thereof, who will then resell or transfer the common stock under this prospectus; or

&nbsp;&nbsp;&nbsp;&nbsp;• loan or pledge the common stock to a broker-dealer or an affiliate thereof, who may sell the loaned common stock or, in an event of default in the case of a pledge, sell the pledged common stock pursuant to this prospectus.

In addition, we may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement or pricing supplement, as the case may be. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement or pricing supplement, as the case may be.

A prospectus supplement with respect to any offering of securities will include the following information:

&nbsp;&nbsp;&nbsp;&nbsp;• the terms of the offering;

&nbsp;&nbsp;&nbsp;&nbsp;• the names of any underwriters or agents;

&nbsp;&nbsp;&nbsp;&nbsp;• the name or names of any managing underwriter or underwriters;

&nbsp;&nbsp;&nbsp;&nbsp;• the purchase price or initial public offering price of the securities;

&nbsp;&nbsp;&nbsp;&nbsp;• the net proceeds from the sale of the securities;

&nbsp;&nbsp;&nbsp;&nbsp;• the allocation or use of proceeds from the sale of the securities;

&nbsp;&nbsp;&nbsp;&nbsp;• the booking of the debt resulting from the sale of the securities by one or more of our branches or subsidiaries;

5<br>

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• any delayed delivery arrangements;

&nbsp;&nbsp;&nbsp;&nbsp;• any underwriting discounts, commissions and other items constituting underwriters' compensation;

&nbsp;&nbsp;&nbsp;&nbsp;• any discounts or concessions allowed or reallowed or paid to dealers;

&nbsp;&nbsp;&nbsp;&nbsp;• any commissions paid to agents; and

&nbsp;&nbsp;&nbsp;&nbsp;• any securities exchange on which the securities may be listed.

The offer and sale of the securities described in this prospectus by us, the underwriters or the third parties described above may be effected from time to time in one or more transactions, including privately negotiated transactions, either:

&nbsp;&nbsp;&nbsp;&nbsp;• at a fixed price or prices, which may be changed;

&nbsp;&nbsp;&nbsp;&nbsp;• at market prices prevailing at the time of sale;

&nbsp;&nbsp;&nbsp;&nbsp;• at prices related to the prevailing market prices;

&nbsp;&nbsp;&nbsp;&nbsp;• at negotiated prices; or

&nbsp;&nbsp;&nbsp;&nbsp;• through a rights offering or similar arrangement.

#### At-the-Market Offerings
If we reach an agreement with an underwriter on a placement, including the number of shares of stock to be offered in the placement and any minimum price below which sales may not be made, such underwriter would agree to use its commercially reasonable efforts, consistent with its normal trading and sales practices, to try to sell such shares on such terms. Underwriters could make sales in privately negotiated transactions, which may be at a discount to the market price of securities, and/or any other method permitted by law, including sales deemed to be an "at-the-market" offering as defined in Rule 415 promulgated under the Securities Act, sales made directly on the New York Stock Exchange and the Lima Stock Exchange, the existing trading markets for our stock, or sales made to or through a market maker other than on an exchange. The name of any such underwriter or agent involved in the offer and sale of our stock, the amounts underwritten or otherwise offered through the underwriter or agent, and the nature of its obligations to take our stock will be described in the applicable prospectus supplement.

#### Sale through Underwriters or Dealers
If underwriters are used in a sale, they will acquire the offered securities for their own account. The underwriters may resell the offered securities in one or more transactions, including negotiated transactions. These sales may be made at a fixed public offering price or prices, which may be changed, at market prices prevailing at the time of the sale, at prices related to such prevailing market price or at negotiated prices. We may offer the securities to the public through an underwriting syndicate or through a single underwriter. The underwriters in any particular offering will be mentioned in the applicable prospectus supplement or pricing supplement, as the case may be.

Unless otherwise specified in connection with any particular offering of securities, the obligations of the underwriters to purchase the offered securities will be subject to certain conditions contained in an underwriting agreement that we will enter into with the underwriters at the time of the sale to them. The underwriters will be obligated to purchase all of the securities of the series offered if any of the securities are purchased, unless otherwise specified in connection with any particular offering of securities. Any initial offering price and any discounts or concessions allowed, reallowed or paid to dealers may be changed from time to time.

We may designate agents to sell the offered securities. Unless otherwise specified in connection with any particular offering of securities, the agents will agree to use their best efforts to solicit purchases for the period of their appointment. We may also sell the offered securities to one or more remarketing firms, acting as principals for their own accounts or as agents for us. These firms will remarket the offered securities upon purchasing them in accordance with a redemption or repayment pursuant to the terms of the offered securities. A prospectus supplement or pricing supplement, as the case may be, will identify any remarketing firm and will describe the terms of its agreement, if any, with us and its compensation.

In connection with offerings made through underwriters or agents, we may enter into agreements with such underwriters or agents pursuant to which we receive our outstanding securities in consideration for the securities being offered to the public for cash. In connection with these arrangements, the underwriters or agents may also sell securities

6<br>

------

#### **TABLE OF CONTENTS**
covered by this prospectus to hedge their positions in these outstanding securities, including in short sale transactions. If so, the underwriters or agents may use the securities received from us under these arrangements to close out any related open borrowings of securities.

If dealers are used in the sale of securities, we will sell the securities to them as principals. We may negotiate and pay dealers' commissions, discounts or concessions for their services. The dealer may then resell such securities to the public either at varying prices to be determined by the dealer or at a fixed offering price agreed to with us at the time of resale. Dealers engaged by us may allow other dealers to participate in resales. We will include in the applicable prospectus supplement or pricing supplement the names of the dealers and the terms of the transaction.

#### Direct Sales and Sales through Agents
We may sell the securities directly. In this case, no underwriters or agents would be involved. We may also sell the securities through agents designated by us from time to time. In the applicable prospectus supplement or pricing supplement, we will name any agent involved in the offer or sale of the offered securities, and we will describe any commissions payable to the agent. Unless we inform you otherwise in the applicable prospectus supplement or pricing supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

#### Institutional Purchasers
We may authorize agents, dealers or underwriters to solicit certain institutional investors to purchase offered securities on a delayed delivery basis pursuant to delayed delivery contracts providing for payment and delivery on a specified future date. The applicable prospectus supplement or pricing supplement, as the case may be will provide the details of any such arrangement, including the offering price and commissions payable on the solicitations.

We will enter into such delayed contracts only with institutional purchasers that we approve. These institutions may include commercial and savings banks, insurance companies, pension funds, investment companies and educational and charitable institutions.

#### Indemnification; Other Relationships
We may have agreements with agents, underwriters, dealers and remarketing firms to indemnify them against certain civil liabilities, including liabilities under the Securities Act. Agents, underwriters, dealers and remarketing firms, and their affiliates, may engage in transactions with, or perform services for, us in the ordinary course of business. This includes commercial banking and investment banking transactions.

#### Market-Making, Stabilization and Other Transactions
There is currently no market for any of the offered securities, other than the common stock which is listed on the New York Stock Exchange and the Lima Stock Exchange. If the offered securities are traded after their initial issuance, they may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar securities and other factors. While it is possible that an underwriter could inform us that it intends to make a market in the offered securities, such underwriter would not be obligated to do so, and any such market-making could be discontinued at any time without notice. Therefore, no assurance can be given as to whether an active trading market will develop for the offered securities. We have no current plans for listing of the debt securities on any securities exchange; any such listing with respect to any particular debt securities will be described in the applicable prospectus supplement or pricing supplement, as the case may be.

In connection with any offering of common stock, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, syndicate covering transactions and stabilizing transactions. Short sales involve syndicate sales of common stock in excess of the number of shares to be purchased by the underwriters in the offering, which creates a syndicate short position. "Covered" short sales are sales of shares made in an amount up to the number of shares represented by the underwriters' over-allotment option. In determining the source of shares to close out the covered syndicate short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. Transactions to close out the covered syndicate short involve either purchases of the common stock in the open market after the distribution has been completed or the exercise of the over-allotment option. The underwriters may also make "naked" short sales of shares in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares of common stock in the open market. A naked short

7<br>

------

#### **TABLE OF CONTENTS**
position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of bids for or purchases of shares in the open market while the offering is in progress for the purpose of pegging, fixing or maintaining the price of the securities.

In connection with any offering, the underwriters may also engage in penalty bids. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

#### General Information
Any public offering price and any discounts, commissions, concessions or other items constituting compensation allowed or reallowed or paid to underwriters, dealers, agents or remarketing firms may be changed from time to time. Underwriters, dealers, agents and remarketing firms that participate in the distribution of the offered securities may be "underwriters" as defined in the Securities Act. Any discounts or commissions they receive from us and any profits they receive on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act. We will identify any underwriters, agents or dealers and describe their commissions, fees or discounts in the applicable prospectus supplement or pricing supplement, as the case may be.

In compliance with the guidelines of the Financial Industry Regulatory Authority (the "FINRA"), the maximum commission or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus or any applicable prospectus supplement.

See "Where You Can Find More Information."*

#### Common Stock
We have one class of common stock. All holders of our common stock are entitled to the same rights and privileges, as described below.

*Voting Rights. Each share of our common stock is entitled to one vote. Except with respect to the election and removal of directors and certain other limited circumstances, all matters relating to stockholder action will be decided by a majority of the votes cast in person, by proxy or by any permissible means of remote communication, including electronic transmission or telephonic means by the stockholders entitled to vote on any such matters. The presence in person, by proxy or by any permissible means of remote communication, including electronic transmission or telephonic means of stockholders holding of record in the aggregate a majority of the outstanding shares of our common stock constitute a quorum for purposes of voting.* 

Our certificate of incorporation provides the holders of our common stock with the right to elect a number of directors as fixed from time to time by resolution of a majority of our board of directors. In all elections of directors, each share of our common stock is entitled to one vote and directors will be elected by a plurality of the votes cast at any such election by the holders of our common stock who are entitled to vote.

Under our by-laws, holders of 10% of our common stock have the right to call special meetings of our stockholders.

*Special Independent Directors and Our Special Nominating Committee. The Special Nominating Committee functions as a special committee to nominate special independent directors to the Board of Directors. The Company does not have any other nominating committee. Pursuant to our Certificate, a special independent director is any director who (i) satisfies the independence requirements of the NYSE Listed Company Manual (or any other exchange or association on which the Common Stock is listed) and (ii) is nominated by the Special Nominating Committee. The Special Nominating Committee has the right to nominate a number of special independent directors based on the percentage of our Common Stock owned by all holders of our Common Stock, other than Grupo Mexico and its affiliates.* 

Our Certificate provides that the minimum number of special independent directors on the Board of Directors at any given time shall be equal to (a) the total number of directors on the Board of Directors multiplied by (b) the percentage of Common Stock owned by all of the stockholders (other than Grupo Mexico and its affiliates), rounded up to the next whole number. Notwithstanding the foregoing, the total number of persons nominated as special independent directors cannot be less than two or greater than six.

*Dividends. Holders of our common stock are entitled to receive proportionately any dividends as may be declared by our board of directors, subject to any preferential dividend rights of outstanding preferred stock.*

*Other Rights. Holders of our common stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges of holders of our common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.* 

*Listing. Our common stock is listed on the New York Stock Exchange under the symbol "SCCO" and on the Lima Stock Exchange pursuant to local applicable Peruvian regulations.*

#### Anti-takeover Effects of Delaware Law and our Certificate of Incorporation and By-laws
Our certificate of incorporation and by-laws and Delaware law contain provisions that could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors.

*Special Meetings Only Callable By Holders of 10% of our Common Stock. Our by-laws provide that special meetings of the stockholders may be called only by the chairman of the board, the president, the board pursuant to a resolution adopted by eight directors or the holders of 10% or more of our common stock.* 

*Board Vacancies to Be Filled by Remaining Directors and Not Stockholders. Our certificate of incorporation and our by-laws provide that any vacancies on our board will be filled by the affirmative vote of the majority of the remaining directors, even if such directors constitute less than a quorum. No vacancy will be filled by our stockholders.* 

*Delaware law. We are a Delaware corporation and consequently are also subject to certain anti-takeover provisions of the Delaware General Corporation Law ("DGCL"). Subject to certain exceptions, in general, Section 203 prohibits a publicly-held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years following the date the person became an interested stockholder, unless (with certain exceptions) the "business combination" or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a "business combination" includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. Generally, an "interested stockholder" is a person who, together with affiliates and associates, owns (or within three years prior to the determination of interested stockholder status, did own) 15% or more of a corporation's voting stock. This statute could prohibit or delay mergers or other takeover or change in control attempts not approved in advance by our board of directors, and as a result could discourage attempts to acquire us, which could depress the market price of our common stock.*

#### General Information
We may sell the debt securities, including original issue discount securities, at par or at a substantial discount below their stated principal amount. Unless we inform you otherwise in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series or any other series outstanding at the time of issuance. These additional notes may be consolidated and form a single series with the applicable series of notes offered, and have the same terms as to status, redemption or otherwise as the applicable series of notes offered; provided that if the additional notes are not fungible with the applicable series of notes offered for U.S. federal income tax purposes, the additional notes will have a new CUSIP number or an ISIN number. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of securities under the Indenture. In addition, we will describe in the applicable prospectus supplement, material U.S. federal income tax considerations and any other special considerations for any debt securities we sell which are denominated in a currency or currency unit other than U.S. dollars. Unless we inform you otherwise in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange.

We expect most debt securities to be issued in fully registered form without coupons and in denominations of U.S.$2,000 and integral multiples of U.S.$1,000 in excess thereof. Subject to the limitations provided in the Indenture and in the prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the designated corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

#### Global Securities
Unless we inform you otherwise in the applicable prospectus supplement, the debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement. Global securities will be issued in registered form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to any debt securities of a series and the rights of and limitations upon owners of beneficial interests in a global security will be described in the applicable prospectus supplement.

| **Item 15.**<br>| ***Indemnification of Directors and Officers.***  |

---

Set forth below is a description of certain provisions of the certificate of incorporation and by-laws of SCC and the DGCL, as such provisions relate to the indemnification of the directors and officers of the registrant. This description is intended only as a summary and is qualified in its entirety by reference to the certificate of incorporation, the by-laws and the DGCL.

The certificate of incorporation provides that SCC shall, to the full extent permitted by Sections 102 and 145 of the DGCL, indemnify all persons whom it may indemnify pursuant thereto and eliminates the personal liability of its directors to the full extent permitted by Section 102(b)(7) of the DGCL.

Section 145 of the DGCL permits a corporation to indemnify its directors and officers against expenses (including attorneys' fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by them in connection with any action, suit or proceeding brought by third parties, if such directors or officers 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, if they had no reasonable cause to believe their conduct was unlawful. In a derivative action, i.e. one by or in the right of the corporation, indemnification may be made only for expenses actually and reasonably incurred by directors and officers in connection with the defense or settlement of an action or suit, and only with respect to a matter as to which they shall have acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made if such person shall have been adjudged liable for negligence or misconduct in the performance of his respective duties to the corporation, although the court in which the action or suit was brought may determine upon application that the defendant officers or directors are reasonably entitled to indemnity for such expenses despite such adjudication of liability.

Section 102(b)(7) of the DGCL provides that a corporation may eliminate or limit the personal liability of a director or officer to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, provided that such provisions shall not eliminate or limit the liability of a director or officer (i) for any breach of the director's or officer'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) with respect to directors, under Section 174 of the DGCL, (iv) for any transaction from which the director derived an improper personal benefit, or (v) with respect to officers, in any action by or in the right of the corporation. No such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision becomes effective.

#### **TABLE OF CONTENTS**
SCC also maintains, at its expense, a policy of insurance which insures its directors and officers, subject to certain exclusions or deductions as are usual in such insurance policies, against certain liabilities which may be incurred in those capacities, including liabilities arising under the Securities Act. The registrant has also entered into agreements with its directors and officers which provide them with indemnification against such liabilities to the fullest extent permitted by law.

(a)<br> The undersigned registrant hereby undertakes:

(1)<br> To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)<br> To include any prospectus required by section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and 

(iii)<br> To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

*provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.* 

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 

(3)<br> To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)<br> That, for the purpose of determining liability under the Securities Act to any purchaser:

(i)<br> Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering

thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: 

(i)<br> Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)<br> Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)<br> The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)<br> Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 

(c)<br> The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the TIA in accordance with rules and regulations prescribed by the SEC under Section 305(b)(2) of the TIA.

(d)<br> The undersigned registrant hereby further undertakes that:

(1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of the registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective. 

(2) For the purposes of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 

(e) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Re: Southern Copper Corporation<br> <u>Registration Statement on Form S-3</u>

Ladies and Gentlemen:

We have acted as special United States counsel to Southern Copper Corporation, a Delaware corporation (the "Company"), in connection with the registration statement on Form S-3 (the "Registration Statement") to be filed on the date hereof by the Company with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933 (the "Securities Act"). The Registration Statement relates to the issuance and sale by the Company from time to time, pursuant to Rule 415 of the General Rules and Regulations of the Commission promulgated under the Securities Act (the "Rules and Regulations"), of (i) shares of common stock, par value $0.01 per share, of the Company ("Common Stock"), (ii) debt securities of the Company ("Debt Securities"), which may be issued in one or more series under the indenture, dated as of April 16, 2010 (the "Base Indenture"), entered into between the Company and Computershare Trust Company, National Association (as successor to Wells Fargo Bank, National Association), as trustee (in such capacity, the "Trustee"), which is filed as an exhibit to the Registration Statement and (iii) such indeterminate number of shares of Common Stock and indeterminate amount of Debt Securities as may be issued upon conversion, exchange or exercise, as applicable, of any Debt Securities, including such shares of Common Stock as may be issued pursuant to anti-dilution adjustments determined at the time of offering (collectively, "Indeterminate Securities"). The Common Stock, Debt Securities and Indeterminate Securities offered pursuant to the Registration Statement are collectively referred to herein as the "Securities."

This opinion letter is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) an executed copy of the Base Indenture;

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents as we have deemed necessary or appropriate as a basis for the opinions stated below.

Southern Copper Corporation

June 15, 2026

In our examination, we have assumed the genuineness of all signatures, including electronic signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified or photocopied copies, and the authenticity of the originals of such copies. As to any facts relevant to the opinions stated herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and others and of public officials, including the facts and conclusions set forth in the Secretary's Certificate, the Certificate of Incorporation and the factual representations and warranties contained in the Secretary's Certificate.

We do not express any opinion with respect to the laws of any jurisdiction other than (i) the laws of the State of New York, and (ii) the General Corporation Law of the State of Delaware (the "DGCL") (all of the foregoing being referred to as "Opined-on Law"). The Securities may be issued from time to time on a delayed or continuous basis, and this opinion letter is limited to the laws, including the rules and regulations, as in effect on the date hereof, which laws are subject to change with possible retroactive effect.

Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. With respect to any shares of Common Stock offered by the Company, including any Indeterminate Securities constituting Common Stock (the "Offered Common Stock"), when (a) the general conditions shall have been satisfied, (b) if the Offered Common Stock is to be certificated, certificates in the form required under the DGCL representing the shares of Offered Common Stock are duly executed and countersigned or, if the Offered Common Stock is to be issued in uncertificated form, a resolution of the Board of Directors has duly authorized the issuance of the Offered Common Stock in uncertificated form and (c) the shares of Offered Common Stock are registered in the Company's share registry and delivered upon payment of the agreed-upon consideration therefor, the shares of Offered Common Stock, when issued and sold or otherwise distributed in accordance with the provisions of the applicable Transaction Document, will be duly authorized by all requisite corporate action on the part of the Company under the DGCL and validly issued, fully paid and nonassessable, provided that the consideration therefor is not less than $0.01 per share of Common Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. With respect to any series of Debt Securities offered by the Company, including any Indeterminate Securities constituting Debt Securities of such series (the "Offered Debt Securities"), when (a) the general conditions shall have been satisfied, (b) the issuance, sale and terms of the Offered Debt Securities and related matters have been approved and established in conformity with the applicable Transaction Documents and (c) the certificates evidencing the Offered Debt Securities have been issued in a form that complies with the provisions of the applicable Transaction Documents and have been duly executed and authenticated in accordance with the provisions of the Indenture and any other applicable Transaction Documents and issued and sold or otherwise distributed in accordance with the provisions of the applicable Transaction Document upon payment of the agreed-upon consideration therefor, the Offered Debt Securities will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms under the laws of the State of New York.

The opinions stated herein are subject to the following assumptions and qualifications:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) we do not express any opinion with respect to the effect on the opinions stated herein of any bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer, preference and other similar laws or governmental orders affecting creditors' rights generally, and the opinions stated herein are limited by such laws and governmental orders and by general principles of equity (regardless of whether enforcement is sought in equity or at law);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) we do not express any opinion with respect to any law, rule, regulation or order that is applicable to any party to any of the Transaction Documents or the transactions contemplated thereby solely because such law, rule, regulation or order is part of a regulatory regime applicable to any such party or any of its affiliates as a result of the specific assets or business operations of such party or such affiliates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) except to the extent expressly stated in the opinions contained herein, we have assumed that each of the Transaction Documents constitutes the valid and binding obligation of each party to such Transaction Document, enforceable against such party in accordance with its terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) we do not express any opinion with respect to the enforceability of any provision contained in any Transaction Document relating to any indemnification, contribution, non-reliance, exculpation, release, limitation or exclusion of remedies, waiver or other provisions having similar effect that may be contrary to public policy or violative of federal or state securities laws, rules, regulations or orders, or to the extent any such provision purports to waive or alter, or has the effect of, waiving or altering any statute of limitations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) we call to your attention that irrespective of the agreement of the parties to any Transaction Document, a court may decline to hear a case on grounds of forum non conveniens or other doctrine limiting the availability of such court as a forum for resolution of disputes; in addition, we call to your attention that we do not express any opinion with respect to the subject matter jurisdiction of the federal courts of the United States of America in any action arising out of or relating to any Transaction Document;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the opinions stated herein are limited to the agreements and documents specifically identified in the opinions contained herein (the "Specified Documents") without regard to any agreement or other document referenced in any Specified Document (including agreements or other documents incorporated by reference or attached or annexed thereto) and without regard to any other agreement or document relating to any Specified Document that is not a Transaction Document;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) subsequent to the effectiveness of the Indenture and immediately prior to the issuance of any series Offered Debt Securities, the Indenture has not been amended, restated, supplemented or otherwise modified in any way that affects or relates to such series of Offered Debt Securities other than by the applicable Transaction Documents relating to such series of Offered Debt Securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) this opinion letter shall be interpreted in accordance with customary practice of United States lawyers who regularly give opinions in transactions of this type;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) we have assumed that the laws of the State of New York law will be chosen to govern any Transaction Documents entered into subsequent to the date hereof and that such choice is and will be a valid and legal provision;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) we do not express any opinion as to the creation, validity, perfection or priority of any security interest; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) to the extent that any opinion relates to the enforceability of the choice of New York law and choice of New York forum provisions contained in any Transaction Document, the opinions stated herein are subject to the qualification that such enforceability may be subject to, in each case, (i) the exceptions and limitations in New York General Obligations Law Sections 5-1401 and 5-1402 and (ii) principles of comity and constitutionality.

In addition, in rendering the foregoing opinions we have also assumed that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) neither the execution and delivery by the Company of the Transaction Documents nor the performance by the Company of its obligations thereunder, including the issuance and sale of the applicable Securities: (i) constitutes or will constitute a violation of, or a default under, any lease, indenture, agreement or other instrument to which the Company or its property is subject, (ii) contravenes or will contravene any order or decree of any governmental authority to which the Company or its property is subject, or (iii) violates or will violate any law, rule or regulation to which the Company or its property is subject (except that we do not make the assumption set forth in this clause (iii) with respect to the Opined-on Law); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) neither the execution and delivery by the Company of the Transaction Documents nor the performance by the Company of its obligations thereunder, including the issuance and sale of the applicable Securities, requires or will require the consent, approval, licensing or authorization of, or any filing, recording or registration with, any governmental authority under any law, rule or regulation of any jurisdiction.

We hereby consent to the reference to our firm under the heading "Legal Matters" in the prospectus forming part of the Registration Statement. We also hereby consent to the filing of this opinion letter with the Commission as an exhibit to the Registration Statement. In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the Rules and Regulations.
