At March 31, 2019, Grupo Mexico through its wholly-owned subsidiary Americas Mining Corporation (“AMC”) owned 88.9% of the Company’s capital stock. The condensed consolidated financial statements presented herein consist of the accounts of Southern Copper Corporation (“SCC” or the “Company”), a Delaware corporation, and its subsidiaries. The Company is an integrated producer of copper and other minerals, and operates mining, smelting and refining facilities in Peru and Mexico. The Company conducts its primary operations in Peru through a registered branch (the “Peruvian Branch” or “Branch” or “SPCC Peru Branch”). The Peruvian Branch is not a corporation separate from the Company. The Company’s Mexican operations are conducted through subsidiaries. The Company also conducts exploration activities in Argentina, Chile, Ecuador, Mexico and Peru.

In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary to state fairly the Company’s financial position as of March 31, 2019 and the results of operations, comprehensive income, cash flows and changes in equity for the three months ended March 31, 2019 and 2018.

NOTE 3 - INVENTORIES:

Inventories were as follows:

(in millions) |  | At March 31, 2019 |  | At December 31, 2018 |
Inventory, current: |  |  |  |  |
Metals at average cost: |  |  |  |  |

Leaching inventories recognized in cost of sales amounted to $94.1 million and $79.5 million for the first quarter 2019 and 2018, respectively.

NOTE 4 — INCOME TAXES:

The income tax provision and the effective income tax rate for the first quarter 2019 and 2018 consisted of ($ in millions):

|  | 2019 |  | 2018 |
Statutory income tax provision |  | $ | 214.7 |  | $ | 212.3 |
Peruvian royalty |  | 0.4 |  | 1.7 |
Mexican royalty |  | 16.7 |  | 16.1 |
Peruvian special mining tax |  | 6.1 |  | 6.5 |
Income tax provision |  | $ | 237.9 |  | $ | 236.6 |
Effective income tax rate |  | 38.1 | % | 33.6 | %

These provisions include income taxes for Peru, Mexico and the United States. In addition, the Mexican royalty, the Peruvian royalty and the Peruvian special mining tax are included in the income tax provision. The increase in the effective tax rate for the first quarter of 2019 from the same period in the prior year is primarily due to the movement in exchange gain or loss from the appreciation in 2019 of the Mexican peso versus the U.S. dollar measured against the devaluation of the Mexican peso in the same period of 2018, and a SAB 118 adjustment to the valuation allowance in the first quarter of 2018, which is not applicable for the first quarter of 2019.

Peruvian royalty and special mining tax: The mining royalty charge is based on operating income margins with graduated rates ranging from 1% to 12% of operating profits, with a minimum royalty charge assessed at 1% of net sales. If the operating

9

Table of Contents

income margin is 10% or less, the royalty charge is 1% and for each 5% increment in the operating income margin, the royalty charge rate increases by 0.75%, up to a maximum of 12%. The minimum royalty charge assessed at 1% of net sales is recorded as cost of sales and those amounts assessed against operating income are included in the income tax provision. The Company has accrued $6.0 million and $7.1 million of royalty charge in the first quarter 2019 and 2018, respectively, of which $0.4 million and $1.7 million were included in income taxes in 2019 and 2018, respectively.

The special mining tax is based on operating income and its rate ranges from 2% to 8.4%. It begins at 2% for operating income margin up to 10% and increases by 0.4% of operating income for each additional 5% of operating income until 85% of operating income is reached. The Company has accrued $6.1 million and $6.5 million of special mining tax as part of the income tax provision for the first quarter 2019 and 2018, respectively.

Mexican mining royalty: Mexico has a mining royalty charge of 7.5% on earnings before taxes as defined by Mexican tax regulations and an additional royalty charge of 0.5% over gross income from sales of gold, silver and platinum. The Company has accrued $16.7 million and $16.1 million of royalty taxes as part of the income tax provision for the first quarter 2019 and 2018, respectively. In the first quarter of 2019, the Company has paid $85.9 million for year 2018 mining royalty.

Accounting for uncertainty in income taxes: In the first quarter of 2019, there were no changes in the Company’s uncertain tax positions.

NOTE 5 — REVENUE:

On January 1, 2018, the Company adopted FASB Accounting Standards Codification Topic 606 (“ASC 606”), Revenue from Contracts with Customers. Upon adoption by the Company, no cumulative effect adjustment was required to be recognized, as the adoption of the standard did not result in a change to the way the Company recognizes its revenue.

The Company’s net sales were $1,753.4 million in the three months ended March 31, 2019, compared to $1,841.1 million in the same period of 2018. The geographic breakdown of the Company’s sales is as follows (in millions):

Provisionally priced sales: At March 31, 2019, the Company has recorded provisionally priced sales of copper at average forward prices per pound, and molybdenum at the March 31, 2019 market price per pound. These sales are subject to final pricing based on the average monthly London Metal Exchange (“LME”), or New York Commodities Exchange (“COMEX”), copper prices and Dealer Oxide molybdenum prices in the future month of settlement.

Following are the provisionally priced copper and molybdenum sales outstanding at March 31, 2019:

|  | Sales volume (million lbs.) |  | Priced at (per pound) |  | Month of settlement |
Copper |  | 105.0 |  | $ | 2.94 |  | April through July 2019 |
Molybdenum |  | 10.2 |  | $ | 12.13 |  | April through June 2019 |

The provisional sales price adjustment included in accounts receivable and net sales at March, 31, 2019 includes positive adjustments of $2.8 million and $4.1 million for copper and molybdenum, respectively.

Management believes that the final pricing of these sales will not have a material effect on the Company’s financial position or results of operations.

NOTE 6 - ASSET RETIREMENT OBLIGATION:

The Company maintains an asset retirement obligation for its mining properties in Peru, as required by the Peruvian Mine Closure Law. In accordance with the requirements of this law the Company’s closure plans were approved by the Peruvian Ministry of Energy and Mines (“MINEM”). As part of the closure plans, the Company is required to provide annual guarantees over the estimated life of the mines, based on a present value approach, and to furnish the funds for the asset retirement obligation. This law requires a review of closing plans every five years. Currently and for the near-term future, the Company has pledged the value of its Lima office complex and a warehouse in Lima as support for this obligation. The accepted values of these facilities, for this purpose, are of $45.3 million. Through March 2019, the Company has provided guarantees of $37.8 million. The closure cost recognized for this liability includes the cost, as outlined in its closure plans, of dismantling the Toquepala and Cuajone concentrators, the Ilo smelter and refinery, and the shops and auxiliary facilities at the three units. In March 2016, MINEM approved the Mining Closure Plan for the Toquepala expansion project. The closure plan for the Tia Maria project was approved in February 2017. The Company, however, has not recorded a retirement obligation for the Tia Maria project as the construction permit has not been received, and work on the project is on hold. The Company believes that under these circumstances the recording of a retirement obligation is not appropriate. In accordance with requirements of Peruvian law, the Company in December 2017 and February 2018, submitted to MINEM revised closure plans for the Cuajone mine and the Ilo facilities respectively. The revised closure plan for the Ilo facility was approved in January 2019 and after comments received from MINEM, the Company submitted a new revised closure plan for the Cuajone mine. As result of these new estimates, in the first quarter of 2019, the Company has increased the asset retirement obligation by $28.1 million.

In 2010, the Company announced to the Mexican federal environmental authorities its closure plans for the copper smelter plant at San Luis Potosi. The Company developed a program for plant demolition and soil remediation with a cost of $66.2 million. In 2016, the environmental authorities approved the conclusion of the remediation effort. The Company continues studying the possibilities for this property in order to decide whether to sell or develop the property. The Company has recognized an estimated asset retirement obligation for its mining properties in Mexico as part of its environmental commitment. Even though there is currently no enacted law, statute, ordinance, written or oral contract requiring the Company to carry out mine closure and environmental remediation activities, the Company believes that a constructive obligation presently exists based on the remediation requirements caused by the closure of any facility. The overall cost recognized for mining closure in Mexico includes the estimated costs of dismantling concentrators, smelter and refinery plants, shops and other facilities. During 2018, the Company made a change in the estimate for the asset retirement obligation in its Mexican operations, mainly due to a change in the discount rate used to determine such obligation. The effect of this change was a reduction in the asset retirement obligation of $10.4 million, which was recorded in the second quarter of 2018.

Grupo Mexico, the parent and the majority indirect stockholder of the Company, and its affiliates provide various services to the Company. These services are primarily related to accounting, legal, tax, financial, treasury, human resources, price risk assessment and hedging, purchasing, procurement and logistics, sales and administrative and other support services. The Company´s Mexican operations pay Grupo Mexico and the Company´s Peruvian operations pay AMMINCO for these services and expect to continue requiring these services in the future.

In the first quarter of 2019, the Company made donations of $3.4 million to Fundacion Grupo Mexico A.C., an organization dedicated to promoting the social and economic development of the communities close to the Company’s Mexican operations.

In addition, in December 2018, in accordance with the Company´s tax sharing agreement with its parent, the Company´s Peruvian operations advanced $11 million to AMC for the payment of the Company’s portion of the GILTI tax that later was determined not to be necessary. In the first quarter of 2019, this amount was reimbursed to the Company.

The Company’s Mexican operations paid fees for freight services provided by Ferrocarril Mexicano, S.A de C.V. and for construction services provided by Mexico Proyectos y Desarrollos, S.A. de C.V. and its affiliates. All of these companies are subsidiaries of Grupo Mexico.

The Company’s Mexican operations purchased scrap and other residual copper mineral from Asarco LLC, and power from MGE. Both companies are subsidiaries of Grupo Mexico.

In 2005, the Company organized MGE, as a subsidiary of Minera Mexico, for the construction of two power plants to supply power to the Company’s Mexican operations. In May 2010, the Company’s Mexican operations granted a $350 million line of credit to MGE for the construction of the power plants. That line of credit was due on December 31, 2012 and carried an interest rate of 4.4%. In the first quarter of 2012, an indirect subsidiary of Grupo Mexico, acquired 99.999% of MGE through a capital subscription of 1,928.6 million of Mexican pesos (approximately $150 million), reducing Minera Mexico’s participation to less than 0.001%. As consequence of this change in control, MGE became an indirect subsidiary of Grupo Mexico. Additionally, at the same time, MGE paid $150 million to the Company’s Mexican operations partially reducing the total debt. The remaining balance was repaid in the third quarter of 2016.

In 2012, the Company signed a power purchase agreement with MGE, whereby MGE will supply some of the Company’s Mexican operations with power through 2032. MGE has two natural gas-fired combined cycle power generating units, with a net total capacity of 516.2 megawatts and has been supplying power to the Company since December 2013. Currently, MGE is supplying 2.1% of its power output to third-party energy users; compared to 14% at March 31, 2018.

In 2014, Mexico Generadora de Energia Eolica, S. de R.L. de C.V, an indirect subsidiary of Grupo Mexico, located in Oaxaca, Mexico, acquired Eolica el Retiro. Eolica el Retiro is a windfarm with 37 wind turbines. This company started operations in January 2014 and started to sell power to Industrial Minera Mexico and subsidiaries (IMMSA) and other subsidiaries of Grupo

Table of Contents

Peruvian operations: The Company’s operations are subject to applicable Peruvian environmental laws and regulations. The Peruvian government, through the Ministry of Environment (“MINAM”) conducts annual audits of the Company’s Peruvian mining and metallurgical operations. Through these environmental audits, matters related to environmental obligation, compliance with legal requirements, atmospheric emissions, effluent monitoring and waste management are reviewed. The Company believes that it is in material compliance with applicable Peruvian environmental laws and regulations. Peruvian law requires that companies in the mining industry provide assurances for future mine closure and remediation. In accordance with the requirements of this law, the Company’s closure plans were approved by MINEM. See Note 6 “Asset retirement obligation,” for further discussion of this matter.

Air Quality Standards (“AQS”): In June 2017, MINAM enacted a supreme decree which defines new AQS for daily sulfur dioxide in the air. The Company believes that these new AQS will allow Peruvian industry to be more competitive with other countries. As of March 31, 2019, the Company maintains a lower daily average level of µg/m3 of SO2, than those required by the new AQS.

Soil Environmental Quality Standards (“SQS”): In 2013, the Peruvian government enacted SQS applicable to any existing facility or project that generates or could generate the risk of soil contamination in its area of operation or influence. In March 2014, MINAM issued a supreme decree, which established additional provisions for the gradual implementation of SQS.

In accordance with the regulatory requirements, the Company has been working on a characterization phase and a Soil Decontamination Plan (“SDP”) for environmentally impacted sites in each of its operating units (Toquepala, Cuajone, and Ilo) with the assistance of consulting companies. It is estimated that the Toquepala and Cuajone SDP will be presented to the authorities for review and approval at the end of the second quarter of 2019, and the Ilo SDP will be submitted during the third quarter of 2019.

While the Company believes that there is a reasonable possibility that a potential loss contingency may exist, it cannot currently reasonably estimate the amount of the contingency. The Company believes that a reasonable determination of the loss will be possible once the characterization study and the SDP are substantially completed and approved, which is expected for 2020. At that time the Company will be in a position to estimate the remediation cost. Furthermore, the Company does not believe that it can estimate a reasonable range of possible costs until the noted studies have substantially progressed and therefore is not able to disclose a range of costs that is meaningful.

Mexican operations: The Company’s operations are subject to applicable Mexican federal, state and municipal environmental laws, to Mexican official standards, and to regulations for the protection of the environment, including regulations relating to water supply, water quality, air quality, noise levels and hazardous and solid waste.

The principal legislation applicable to the Company’s Mexican operations is the Federal General Law of Ecological Balance and Environmental Protection (the “General Law”), which is enforced by the Federal Bureau of Environmental Protection (“PROFEPA”). PROFEPA monitors compliance with environmental legislation and enforces Mexican environmental laws, regulations and official standards. It may also initiate administrative proceedings against companies that violate environmental laws, which in the most extreme cases may result in the temporary or permanent shutdown of non-complying facilities, the revocation of operating licenses and/or other sanctions or fines.

In 2011, the General Law was amended, giving an individual or entity the ability to contest administrative acts, including environmental authorizations, permits or concessions granted, without the need to demonstrate the actual existence of harm to the environment as long as it can be argued that the harm may be caused. In addition, in 2011, amendments to the Civil Federal Procedures Code (“CFPC”) were enacted. These amendments establish three categories of collective actions by means of which 30 or more people claiming injury derived from environmental, consumer protection, financial services and economic competition issues will be considered to be sufficient in order to have a legitimate interest to seek through a civil procedure restitution or economic compensation or suspension of the activities from which the alleged injury derived. The amendments to the CFPC may result in more litigation, with plaintiffs seeking remedies, including suspension of the activities alleged to cause harm.

In 2013, the Environmental Liability Federal Law was enacted. The law establishes general guidelines for actions to be considered to likely cause environmental harm. If a possible determination regarding harm occurs, environmental clean-up and remedial actions sufficient to restore environment to a pre-existing condition should be taken. Under this law, if restoration is not possible, compensation measures should be provided. Criminal penalties and monetary fines can be imposed under this law.

On February 2019, the Mexican Supreme Court confirmed the constitutionality of an ecological tax to extractive activities developed in the state of Zacatecas, which taxes the environmental remediation actions, emissions of certain gases to the

atmosphere, emissions of pollutant substances to the soil or water, and waste storage within the state territory. The Company is evaluating the potential impact of this new environmental regulation in its financial position.

The Company believes that all of its facilities in Peru and Mexico are in material compliance with applicable environmental, mining and other laws and regulations. The Company also believes that continued compliance with environmental laws of Mexico and Peru will not have a material adverse effect on the Company’s business, properties, result of operations, financial condition or prospects and will not result in material capital investments.

Litigation matters:

Peruvian operations

The Tia Maria Mining Project

There are three lawsuits filed against the Peruvian Branch of the Company related to the Tia Maria project. The lawsuits seek (i) to declare null and void the resolution which approved the Environmental Impact Assessment of the project; (ii) the cancellation of the project and the withdrawal of mining activities in the area and (iii) to declare null and void the mining concession application of the Tia Maria project. The lawsuits were filed by Messrs. Jorge Isaac del Carpio Lazo (filed May 22, 2015), Ernesto Mendoza Padilla (filed May 26, 2015) and Juan Alberto Guillen Lopez (filed June 18, 2015).

The del Carpio Lazio case was rejected by the court of first instance on November 14, 2016. The plaintiff filed an appeal before the Superior Court on January 3, 2017. On January 9, 2018, the lawyers of both parties presented their respective positions before the Appellate Court. On March 8, 2018, the Appellate Court issued its final decision, which upholds the first instance ruling. On April 27, 2018, the plaintiff filed an extraordinary appeal before the Supreme Court. As of March 31, 2019, the case remains pending resolution.

The Mendoza Padilla case was initially rejected by the lower court on July 8, 2015. This ruling was confirmed by the Superior Court on June 14, 2016. On July 12, 2016, the case was appealed before the Constitutional Court. As of March 31, 2019, the case remains pending resolution without further developments.

The Guillen Lopez case is currently before the lower court. As of March 31, 2019, the case remains pending resolution without further developments.

The Company asserts that these lawsuits are without merit and is vigorously defending against them. The potential contingency amount for these cases cannot be reasonably estimated by management at this time.

Special Regional Pasto Grande Project (“Pasto Grande Project”)

In 2012, the Pasto Grande Project, an entity of the Regional Government of Moquegua, filed a lawsuit against SCC’s Peruvian Branch alleging property rights over a certain area used by the Peruvian Branch and seeking the demolition of the tailings dam where SCC’s Peruvian Branch has deposited its tailings from the Toquepala and Cuajone operations since 1995. The Peruvian Branch has had title to use the area in question since 1960 and has constructed and operated the tailings dams with proper governmental authorization, since 1995. Upon a motion filed by the Peruvian Branch, the lower court has included MINEM as a defendant in this lawsuit. MINEM has answered the complaint and denied the validity of the claim. As of March 31, 2019, the case remains pending resolution without further developments. SCC’s Peruvian Branch asserts that the lawsuit is without merit and is vigorously defending against it. The amount of this contingency cannot be reasonably estimated by management at this time.

The Accidental Spill at Buenavista Mine of 2014

In relation to the 2014 accidental spill of copper sulfate solution that occurred at a leaching pond of the Buenavista mine, the following legal procedures are pending against the Company:

On August 19, 2014, PROFEPA, as part of the administrative proceeding initiated after the spill, announced the filing of a criminal complaint against Buenavista del Cobre S.A. de C.V. (“BVC”), a subsidiary of the Company, in order to determine

18

Table of Contents

those responsible for the environmental damages. During the second quarter of 2018, the criminal complaint was dismissed. This decision was appealed and remains pending resolution as of March 31, 2019.

Through the first half of 2015, six collective action lawsuits were filed in federal courts in Mexico City and Sonora against two subsidiaries of the Company seeking economic compensation, clean up and remedial activities in order to restore the environment to its pre-existing conditions. Two of the collective action lawsuits have been dismissed by the court. The plaintiffs in the four remaining lawsuits are: Acciones Colectivas de Sinaloa, A.C. which established two collective actions, Defensa Colectiva A.C.; and Ana Luisa Salazar Medina et al. which has been granted a collective action certification. The remaining plaintiffs have requested cautionary measures on the construction of facilities for the monitoring of public health services and the prohibition of the closure of the Río Sonora Trust. As of March 31, 2019, regarding the case of Ana Luisa Salazar Medina et al, the trial date has expired. Since the plaintiffs were notified of the expiration of their claims and did not appeal the resolution, this lawsuit has concluded, without responsibility for Buenavista del Cobre, S.A. de C.V. The other cases remain pending resolution as of March 31, 2019.

Similarly, during 2015, eight civil action lawsuits were filed against BVC in the state courts of Sonora seeking damages for alleged injuries and for moral damages as a consequence of the spill. The plaintiffs in the state court lawsuits are: Jose Vicente Arriola Nunez et al; Santana Ruiz Molina et al; Andres Nogales Romero et al; Teodoro Javier Robles et al; Gildardo Vasquez Carvajal et al; Rafael Noriega Souffle et al; Grupo Banamichi Unido de Sonora El Dorado, S.C. de R.L. de C.V; and Marcelino Mercado Cruz. In 2016, three additional civil action lawsuits, claiming similar damages, were filed by Juan Melquicedec Lebaron; Blanca Lidia Valenzuela Rivera et al and Ramona Franco Quijada et al. In 2017, BVC was served with thirty-three additional civil action lawsuits, claiming similar damages. The lawsuits were filed by Francisco Javier Molina Peralta et al; Anacleto Cohen Machini et al; Francisco Rafael Alvarez Ruiz et al; Jose Alberto Martinez Bracamonte et al; Gloria del Carmen Ramirez Duarte et al; Flor Margarita Sabori et al; Blanca Esthela Ruiz Toledo et al; Julio Alfonso Corral Domínguez et al; Maria Eduwiges Bracamonte Villa et al; Francisca Marquez Dominguez et al; Jose Juan Romo Bravo et al; Jose Alfredo Garcia Leyva et al; Gloria Irma Dominguez Perez et al; Maria del Refugio Romero et al; Miguel Rivas Medina et al; Yolanda Valenzuela Garrobo et al; Maria Elena Garcia Leyva et al; Manuel Alfonso Ortiz Valenzuela et al; Francisco Alberto Arvayo Romero et al; Maria del Carmen Villanueva Lopez et al; Manuel Martin Garcia Salazar; Miguel Garcia Arguelles et al; Dora Elena Rodriguez Ochoa et al; Honora Eduwiges Ortiz Rodriguez et al; Francisco Jose Martinez Lopez et al; Maria Eduwiges Lopez Bustamante; Rodolfo Barron Villa et al, Jose Carlos Martinez Fernandez et al, Maria de los Angeles Fabela et al; Rafaela Edith Haro et al; Luz Mercedes Cruz et al; Juan Pedro Montaño et al; and Juana Irma Alday Villa. During the first quarter of 2018, BVC was served with another civil action lawsuit, claiming similar damages. The lawsuit was filed by Alma Angelina Del Cid Rivera et al. During the last quarter of 2018, BVC was served with other three civil action lawsuits, claiming similar damages, such lawsuits were filed by Los Corrales de la Estancia, S.C. de R.L.; Jose Antonio Navarro; Jesus Maria Peña Molina, et al. As of March 31, 2019, these cases remain pending resolution.

During 2015, four constitutional lawsuits (juicios de amparo) were filed before Federal Courts against various authorities and against a subsidiary of the Company, arguing; (i) the alleged lack of a waste management program approved by SEMARNAT; (ii) the alleged lack of a remediation plan approved by SEMARNAT with regard to the August 2014 spill; (iii) the alleged lack of community approval regarding the environmental impact authorizations granted by SEMARNAT to one subsidiary of the Company; and (iv) the alleged inactivity of the authorities with regard of the spill in August 2014. The plaintiffs of these lawsuits are: Francisca Garcia Enriquez, et al which established two lawsuits, Francisco Ramon Miranda, et al and Jesus David Lopez Peralta et al. During the third quarter of 2016, four additional constitutional lawsuits, claiming similar damages were filed by Mario Alberto Salcido et al; Maria Elena Heredia Bustamante et al; Martin Eligio Ortiz Gamez et al; and Maria de los Angeles Enriquez Bacame et al. During the third quarter of 2017, BVC was served with another constitutional lawsuit filed by Francisca García Enriquez et al. In 2018, BVC was served with two additional constitutional lawsuits that were filed against SEMARNAT by Norberto Bustamante et al. Regarding the constitutional lawsuit filed by Maria Elena Heredia Bustamante et al; in which it was claimed the lack of community approval regarding the authorization granted by SEMARNAT to build the new BVC tailings dam, on September 5, 2018, the Supreme Court of Justice issued a resolution which established that such authorization was granted to BVC in compliance with the applicable legislation. However, SEMARNAT must carry out a public meeting to inform the community of the technical aspects required to build the dam, potential impacts and prevention measures, with no material effects to BVC’s operations. As of March 31, 2019, the remaining cases are still pending resolution.

It is not currently possible to determine the extent of the damages sought in these state and federal lawsuits but the Company considers that these lawsuits are without merit. Accordingly, the Company is vigorously defending against them. Nevertheless, the Company considers that none of the legal proceedings resulting from the spill, individually or in the aggregate, would have a material effect on its financial position or results of operations.

Corporate operations

Carla Lacey, on behalf of herself and all other similarly situated stockholders of Southern Copper Corporation, and derivatively on behalf of Southern Copper Corporation

As previously reported, a purported class action derivative lawsuit filed in the Delaware Court of Chancery was served on the Company and its Directors in February 2016 relating to the 2012 capitalization of 99.999% of MGE by Controladora de Infraestructura Energetica Mexico, S.A. de C.V., an indirect subsidiary of Grupo Mexico (the “CIEM Capitalization”), the Company’s entry into a power purchase agreement with MGE in 2012 (the “MGE Power Purchase Agreement”), and the 2012 restructuring of a loan from the Company’s Mexican Operations to MGE for the construction of two power plants to supply power to the Company’s Mexican operations (the “MGE Loan Restructuring”). The action purports to be brought on behalf of the Company and its common stockholders. The complaint alleges, among other things, that the CIEM Capitalization, the MGE Power Purchase Agreement and the MGE Loan Restructuring were the result of breaches of fiduciary duties and the Company’s charter.

On March 20, 2018, the parties reached an agreement-in-principle to settle the action. On March 23, 2018, the parties informed the Court of the settlement-in-principle to resolve all claims asserted by Plaintiff against Defendants in the action and requested that the Court stay the action in its entirety pending filing by the parties of a stipulation of settlement. The Parties filed the executed stipulation on August 22, 2018. Under the proposed settlement, Grupo Mexico or Americas Mining would pay to the Company $50 million in cash less any attorneys’ fees (including costs) awarded by the Court to Plaintiff’s counsel (the “Net Settlement Amount”) in return for a release of all derivative and direct claims. A settlement hearing was held on November 27, 2018. On December 27, 2018, the Court issued its ruling approving the $50 million settlement. Pursuant to the Court’s ruling, Plaintiff’s counsel was awarded $13.5 million (for attorneys’ fees, expenses, and a $5,000 incentive fee award to plaintiff Carla Lacey). The remaining $36.5 million was distributed via a special dividend on February 21, 2019 to the Company’s public stockholders (other than the director defendants, Grupo Mexico, Americas Mining, or any entity in which Grupo Mexico or Americas Mining has or had a direct or indirect controlling interest) who held shares of common stock of the Company as of February 11, 2019. As result of the payment of the settlement, the claims against the Defendants have been dismissed with prejudice.

In April 2019, a derivative lawsuit was filed against the Company, certain of its current and former Directors, and Grupo México in the Delaware Court of Chancery relating to certain construction contracts, contracts for the purchase and sale of minerals, and transportation contracts entered into between the Company’s subsidiaries and subsidiaries of Grupo México. The complaint alleges, among other things, that the construction contracts, the mineral contracts and the transportation contracts were unfair as a result of breaches of fiduciary duties and the Company’s charter. The complaint seeks, among other things, unspecified monetary damages. The complaint and the summons have not yet been served. The Company believes it has a meritorious defense to this action and that the action will not have an adverse effect on its financial position.

Labor matters:

Peruvian operations: 70% of the Company’s 4,835 Peruvian employees were unionized at March 31, 2019. Currently, there are six separate unions, one large union and five smaller unions. In June 2018, the Company signed a three-year collective bargaining agreement with one of the smaller unions. This agreement includes, among other things, annual salary increases of 5% for each year starting September 2018, and a signing bonus of S/ 45,000 (approximately $13,600) which was recorded as labor expense. In August 2018, the Company signed a three-year collective bargaining agreement with three additional unions. This agreement includes, among other things, annual salary increases of 5% for each year starting December 2018, and a signing bonus of S/ 45,000 (approximately $13,600) which was recorded as labor expense. In March 2019, the Company signed an agreement with one additional union. The agreement also includes annual salary increases of 5% for each year starting September 2018, and a signing bonus of S/ 45,000 (approximately $13,600) which was recorded as labor expense in the first quarter of 2019.

As of March 31, 2019, the Company continues negotiations on collective bargaining agreements with one unsigned union.

Mexican operations: In recent years, the Mexican operations have experienced a positive improvement of their labor environment, as its workers opted to change their affiliation from the Sindicato Nacional de Trabajadores Mineros, Metalurgicos y Similares de la Republica Mexicana (the “National Mining Union”) to other less politicized unions.

The workers of the San Martin mine were on strike since July 2007. On February 28, 2018, the striking workers of the San Martín mine of IMMSA held an election to vote on the union that will hold the collective bargaining agreement at the San Martín mine. The Federacion Nacional de Sindicatos Independientes (the National Federation of Independent Unions), won the vote by a majority. Nevertheless, the vote was challenged by the National Mining Union. On June 26, 2018, the Federal Mediation and Arbitration Board issued a ruling recognizing the election results. Due to the agreement between workers and the Company to end the protracted strike, on August 22, 2018, the Federal Mediation and Arbitration Board authorized the restart of operations of the San Martín mine. Such authorization was challenged by the National Mining Union. On April 4, 2019, the Federal Mediation and Arbitration Board recognized again the election results from February 28, 2018; in which the

20

Table of Contents

National Federation of Independent Unions won by a majority. The Company is working on a rehabilitation plan to restart operations at the San Martin mine with a budget of $87 million. At March 31, 2019 the plan is in progress with a total expense of $34.9 million. The Company continues with plans to restore mining operations and expects to restore copper production in the second quarter of 2019.

In the case of the Taxco mine, its workers have been on strike since July 2007. After several legal procedures, in August 2015, the Supreme Court decided to assert jurisdiction over the case and to rule on it directly. As of March 31, 2019, the case remains pending resolution without further developments.

It is expected that operations at the Taxco mine will remain suspended until the labor issues are resolved. In view of the lengthy strike, the Company has reviewed the carrying value of the Taxco mine to ascertain whether impairment exists. The Company concluded that there is a non-material impairment of the assets located at this mine.

Other legal matters:

The Company is involved in various other legal proceedings incidental to its operations, but the Company does not believe that decisions adverse to it in any such proceedings, individually or in the aggregate, would have a material effect on its financial position or results of operations.

Other commitments:

Peruvian Operations

Tia Maria:

On August 1, 2014, the Company received the final approval of Tia Maria´s Environmental Impact Assessment (“EIA”). However, the issuance of the project´s construction permit has been delayed due to pressures from anti-mining groups. The Company continues working with community groups in order to resolve open issues concerning the project. The Company is also working jointly with the Peruvian government to obtain the construction license for this 120,000 ton (annual) SX-EW copper greenfield project. The Company expects the license to be issued in the first half of 2019.

Tia Maria´s project budget is approximately $1.4 billion, of which $333.3 million has been invested through March 31, 2019. When completed, it is expected to produce 120,000 tons of copper cathodes per year. This project will use state-of-the-art SX-EW technology with the highest international environmental standards. SX-EW facilities are the most environmentally friendly in the industry as they do not require a smelting process and consequently, no emissions are released into the atmosphere. The project will only use seawater, transporting it more than 25 kilometers to 1,000 meters above sea level, and includes a desalinization plant which will be constructed at a cost of $95 million. Consequently, the Tambo river water resources will be used solely for farming and human consumption.

The Company expects the project to generate 9,000 jobs (3,600 direct and 5,400 indirect) during the construction phase. When in operation, Tia Maria will directly employ 600 workers and indirectly provide jobs to another 4,200. Through its expected twenty-year life, the project related services will create significant business opportunities in the Arequipa region.

In view of the delay in this project, the Company continues to review the carrying value of this asset to ascertain whether impairment exists. Should the Tia Maria project not move forward, the Company is confident that most of the project equipment will continue to be used productively, through reassignment to other mine locations operated by the Company. The Company believes that an impairment loss, if any, will not be material.

Michiquillay:

In June 2018, the Company signed a contract for the acquisition of the Michiquillay copper project in Cajamarca, Peru, at a purchase price of $400 million. Michiquillay is a world class mining project with estimated mineralized material of 1,150 million tons and a copper grade of 0.63%. It is expected to produce 225,000 tons of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years.

The Company paid $12.5 million at the signing of the contract. The balance of $387.5 million will be paid if the Company decides to develop the project and it is not a present obligation.

Toquepala Concentrator Expansion:

In April 2015, the construction permit for the Toquepala expansion project was approved by the MINEM. The project budget is $1,320 million, of which $1,240.9 million has been invested through March 31, 2019. When completed, this project is expected to increase Toquepala’s annual copper production to 258,000 tons in 2019, a 52% production increase, when compared to 2018. The construction of the project was completed and the project began production in the fourth quarter of 2018. Full production is expected to be reached by the second quarter of 2019.

Corporate Social Responsibility:

The Company has a corporate social responsibility policy to maintain and promote continuity of its mining operations and obtain the best results. The main objective of this policy is to integrate its operations with the local communities in the areas of influence of its operations by creating a permanent positive relationship with them, in order to develop the optimum social conditions and to promote sustainable development in the area. Accordingly, the Company has made the following commitments:

Tacna Region: In connection with the Toquepala concentrator expansion, the Company has committed to fund various social and infrastructure improvement projects in Toquepala’s neighboring communities. The total amount committed for these purposes is S/ 445.0 million (approximately $131.7 million).

Moquegua Region: In the Moquegua region, the Company is part of a “development roundtable” in which the local municipal authorities, the community representatives and the Company discuss the social needs and the way the Company could contribute to sustainable development in the region. As part of this, the roundtable is discussing the creation of a Moquegua Region Development Fund for which the Company has offered a contribution of S/ 700 million (approximately $207.2 million). While final funding is not yet settled, the Company has committed to contribute S/ 108.5 million (approximately $32.1 million) in advance, which is being utilized in an educational project and S/ 48.4 million (approximately $14.3 million) for a residual water treatment plant in Ilo, a sea-wall embankment and a fresh water facility at El Algarrobal.

In addition, the Company has committed S/ 202.0 million (approximately $59.8 million) for the construction of six infrastructure projects in the Moquegua region under the “social investment for taxes” (obras por impuestos) program which allows the Company to use these amounts as an advance payment of taxes.

These commitments are subject to the continuity of the respective mine operations and, as such, are not considered to be present obligations of the Company. Therefore, the Company has not recorded a liability in its condensed consolidated financial statements.

Power purchase agreements:

· Electroperu S.A.: In June 2014, the Company entered into a power purchase agreement for 120 megawatt (“MW”) with the state power company Electroperu S.A., under which Electroperu S.A. began supplying energy for the Peruvian operations for twenty years starting on April 17, 2017.

· Kallpa Generacion S.A. (“Kallpa”): In July 2014, the Company entered into a power purchase agreement for 120MW with Kallpa, an independent Israeli owned power company, under which Kallpa will supply energy for the Peruvian operations for ten years starting on April 17, 2017 and ending on April 30, 2027. In May 2016, the Company signed an additional power purchase agreement for a maximum of 80MW with Kallpa, under which Kallpa began supplying energy for the Peruvian operations related to the Toquepala Expansion and other minor projects for ten years starting on May 1, 2017 and ending after ten years of commercial operation of the Toquepala Expansion or on April 30, 2029; whichever occurs first.

NOTE 10 — SEGMENT AND RELATED INFORMATION:

Company management views Southern Copper as having three reportable segments and manages it on the basis of these segments. The reportable segments identified by the Company are: the Peruvian operations, the Mexican open-pit operations and the Mexican underground mining operations segment identified as the IMMSA unit.

The three reportable segments identified are groups of mines, each of which constitute an operating segment, with similar economic characteristics, type of products, processes and support facilities, similar regulatory environments, similar employee bargaining contracts and similar currency risks. In addition, each mine within the individual group earns revenues from similar type of customers for their products and services and each group incurs expenses independently, including commercial transactions between groups.

Financial information is regularly prepared for each of the three segments and the results of the Company’s operations are regularly reported to Senior Management on the segment basis. Senior Management of the Company focus on operating income and on total assets as measures of performance to evaluate different segments and to make decisions to allocate resources to the reported segments. These are common measures in the mining industry.

Financial information relating to Southern Copper’s segments is as follows:

Directors’ Stock Award Plan:

The Company established a stock award compensation plan for certain directors who are not compensated as employees of the Company. Under this plan, participants received 1,200 shares of common stock upon election and 1,200 additional shares following each annual meeting of stockholders thereafter. 600,000 shares of Southern Copper common stock have been reserved for this plan. On April 26, 2018, the Company’s Board of Directors and the stockholders approved a five-year extension of the Plan until January 29, 2023 and an increase of the shares award from 1,200 to 1,600. The fair value of the award is measured each year at the date of the grant.

Parent Company common shares:

At March 31, 2019 and 2018 there were in treasury 100,181,108 and 104,479,600 of Grupo Mexico’s common shares, respectively.

Employee Stock Purchase Plan:

2015 Plan: In January 2015, the Company offered to eligible employees a new stock purchase plan through a trust that acquires series B shares of Grupo Mexico stock for sale to its employees, and employees of subsidiaries, and certain affiliated companies. The purchase price was established at 38.44 Mexican pesos (approximately $2.63) for the initial subscription, which expires in January 2023. Every two years employees will be able to acquire title to 50% of the shares paid in the previous two years. The employees will pay for shares purchased through monthly payroll deductions over the eight year period of the plan. At the end of the eight year period, the Company will grant the participant a bonus of 1 share for every 10 shares purchased by the employee. Any future subscription will be at the average market price at the date of acquisition or the grant date.

If Grupo Mexico pays dividends on shares during the eight year period, the participants will be entitled to receive the dividend in cash for all shares that have been fully purchased and paid as of the date that the dividend is paid. If the participant has only partially paid for shares, the entitled dividends will be used to reduce the remaining liability owed for purchased shares.

In the case of voluntary or involuntary resignation/termination of the employee, the Company will pay to the employee the fair market sales price at the date of resignation of the fully paid shares, net of costs and taxes. When the fair market sales value of the shares is higher than the purchase price, the Company will apply a deduction over the amount to be paid to the employee based on a decreasing schedule specified in the plan.

In case of retirement or death of the employee, the Company will render the buyer or his legal beneficiary, the fair market sales value as of the date of retirement or death of the shares effectively paid, net of costs and taxes.

The stock based compensation expense for the first quarter 2019 and 2018 and the unrecognized compensation expense under this plan were as follows (in millions):

NOTE 12 — FAIR VALUE MEASUREMENT:

Subtopic 820-10 of ASC “Fair value measurement and disclosures — Overall” establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under Subtopic 820-10 are described below:

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

26

Table of Contents

Level 2 - Inputs that are observable, either directly or indirectly, but do not qualify as Level 1 inputs. (i.e., quoted prices for similar assets or liabilities).

Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

The carrying amounts of certain financial instruments, including cash and cash equivalents, accounts receivable (other than accounts receivable associated with provisionally priced sales) and accounts payable approximate fair value due to their short maturities. Consequently, such financial instruments are not included in the following table that provides information about the carrying amounts and estimated fair values of other financial instruments that are not measured at fair value in the condensed consolidated balance sheet as of March 31, 2019 and December 31, 2018 (in millions):

|  | At March 31, 2019 |  | At December 31, 2018 |
|  | Carrying Value |  | Fair Value |  | Carrying Value |  | Fair Value |
Liabilities: |  |  |  |  |  |  |  |  |
Long-term debt level 1 |  | $ | 5,211.3 |  | $ | 6,055.4 |  | $ | 5,210.7 |  | $ | 5,540.0 |

Total long-term debt |  | $ | 5,960.9 |  | $ | 6,832.3 |  | $ | 5,960.1 |  | $ | 6,301.7 |

Long-term debt is carried at amortized cost and its estimated fair value is based on quoted market prices classified as Level 1 in the fair value hierarchy except for the cases of the Yankee bonds, the notes due 2020 and the notes due 2022, which qualify as Level 2 in the fair value hierarchy as they are based on quoted priced in market that are not active.

Fair values of assets and liabilities measured at fair value on a recurring basis were calculated as follows as of March 31, 2019 and December 31, 2018 (in millions):

The Company’s short-term trading securities investments are classified as Level 1 because they are valued using quoted prices of the same securities as they consist of bonds issued by public companies and publicly traded. The Company’s short-term available-for-sale investments are classified as Level 2 because they are valued using quoted prices for similar investments.

The Company’s accounts receivables associated with provisionally priced copper sales are valued using quoted market prices based on the forward price on the LME or on the COMEX. Such value is classified within Level 1 of the fair value hierarchy. Molybdenum prices are established by reference to the publication Platt’s Metals Week and are considered Level 1 in the fair value hierarchy.

NOTE 13 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

ADOPTION OF LEASES STANDARD

The Company has adopted FASB ASC 842, Leases, effective January 1, 2019, applying the transition approach which permits it to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, the financial statements for prior periods were not modified. At the date of adoption, the Company assessed that the adoption of the new leases standard has resulted in the recognition of right of use assets and lease obligations of approximately $1,115.9 million, which was recorded in the Company’s balance sheet as of January 1, 2019.

During 2018, the Company developed an implementation plan with a cross-functional team, which performed a completeness assessment over the lease contracts of the Company, established new policies, procedures and internal controls related to the new standard. As result of its analysis, the Company has concluded that all of its existing lease contracts at January 1, 2019, have been classified as operating lease contracts.

Additionally, the Company has elected the short-term lease recognition exemption (short-term lease practical expedient) by class of underlying asset (which results in off-balance-sheet accounting for the lease). The new standard had a material impact on the Company’s balance sheet, but did not have a material impact on its income statement and had no impact on cash flows.

SIGNIFICANT ACCOUNTING POLICIES

With the exception of the change in the Company’s leases policy as a result of the adoption of ASC 842, as described above, there have been no new or material changes to the significant accounting policies discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, that are of significance, or potential significance to the Company.

Leases -

The Company adopted FASB ASC 842, Leases, effective January 1, 2019. The Company determined if a contract is or contained a lease at its inception. The Company evaluated if a contract gave the right to obtain substantially all of the economic benefits from use of an identified asset and the right to direct the use of the asset, in order to determine if a contract contained a lease. All of the Company’s existing lease contracts are operating lease contracts. For these leases, the Company recognized right-of-use assets and the corresponding operating lease liabilities on its consolidated balance sheet. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation by the Company to make lease payments which arise from the lease. Lease right-of-use assets and liabilities are recognized at the inception date based on the present value of lease payments over the lease term. As the Company’s lease contracts do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the inception date in order to determine the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the lease term, in the cost of sales and operating expenses.

NOTE 14 — LEASES:

The Company has operating leases for power generating facilities, vehicles and properties. Leases with an initial term of 12 months or less, underlying asset value of $10,000 (US dollars) or less and total nominal contract value of $100,000 (US dollars) or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. Some of the Company’s leases include both lease and non-lease components which are accounted for separately. The Company’s leases have remaining lease terms of two years to 14 years, and do not include options to extend the leases. The Company’s lease agreements do not contain options to purchase the leased assets or to terminate the leases before the expiration date. In addition, the Company’s lease contracts do not have any material residual value guarantees or material restrictive covenants. As none of the Company’s leases provides an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.

The weighted average remaining lease term for the Company’s leases is 10 years, and the weighted average discount rate for these leases is 3.56%.

The operating lease expense recognized in the three months ended March 31, 2019 was classified as follows (in millions):

Classification |  | 2019 |
Cost of sales (exclusive of depreciation, amortization and depletion) |  | $ | 28.8 |
Selling, general and administrative |  | 0.1 |
Exploration |  | (* | )
Total lease expense |  | $ | 28.9 |

(*) amount is lower than $0.1 million

The Company’s short-term lease costs for the three months ended March 31, 2019 was $0.2 million.

Maturities of lease liabilities were as follows:

|  | Lease liabilities |
Year |  | (in millions) |
2019 |  | $ | 86.7 |
2020 |  | 115.4 |
2021 |  | 115.3 |

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion provides information that management believes is relevant to an assessment and understanding of the condensed consolidated financial condition and results of operations of Southern Copper Corporation and its subsidiaries (collectively, “SCC”, “the Company”, “our”, and “we”). This item should be read in conjunction with our interim unaudited Condensed Consolidated Financial Statements and the notes thereto included in this quarterly report. Additionally, the following discussion and analysis should be read in conjunction with the Management Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements included in Part II of our annual report on Form 10-K for the year ended December 31, 2018.

EXECUTIVE OVERVIEW

Business: Our business is primarily the production and sale of copper. In the process of producing copper, a number of valuable metallurgical by-products are recovered, which we also produce and sell. Market forces outside of our control largely determine the sale prices for our products. Our management, therefore, focuses on value creation through copper production, cost control, production enhancement and maintaining a prudent capital structure to remain profitable. We endeavor to achieve these goals through capital spending programs, exploration efforts and cost reduction programs. Our aim is to remain profitable during periods of low copper prices and to maximize financial performance in periods of high copper prices.

We are one of the world’s largest copper mining companies in terms of production and sales with our principal operations in Peru and Mexico. We also have active ongoing exploration programs in Chile, Argentina and Ecuador. In addition to copper, we produce significant amounts of other metals, either as a by-product of the copper process or in a number of dedicated mining facilities in Mexico.

Outlook: Various key factors will affect our outcome. These include, but are not limited to, some of the following:

· Changes in copper, molybdenum, silver and zinc prices: In the first quarter of 2019, the average LME and COMEX copper prices were $2.82 and $2.81 per pound, respectively, about 10.8% and 10.5% lower than in the first quarter of 2018, respectively. During the first quarter of 2019 per pound LME spot copper prices ranged from $2.64 to $2.98. Average molybdenum and zinc prices in the first quarter of 2019 decreased 3.6% and 20.6%, respectively, when compared to the average prices in the first quarter of 2018. Average silver prices decreased 7.0% in the first quarter of 2019 when compared to the same period of 2018.

· Sales structure: In the first quarter of 2019, approximately 80.7% of our revenue came from the sale of copper, 6.7% from molybdenum, 4.4% from zinc, 4.4% from silver and 3.8% from various other products, including gold, sulfuric acid and other materials.

· Copper: During the first quarter of 2019 the LME copper price decreased, from an average of $3.16 per pound in the first quarter of 2018 to $2.82 (-10.8%). Even though we see a good physical market for copper, we believe the fall in prices of the prior quarter reflected the sentiment of a possible slowdown of the World economy, concerns with Brexit and an escalation of trade protectionism between the United States and China. We expect a recovery in copper prices in the coming months. We maintain our view of a total demand growth of 2.5% for refined copper in 2019, driven by higher consumption in the U.S. and Asia, with China demanding 3.5% more refined copper than in 2018.

On the supply side, during the past quarter we had production losses in Chile and Peru due to heavy rain estimated at 165,000 tons. As a consequence, we now expect a slight deficit for this year.

· Molybdenum: Represented 6.7% of our sales in the first quarter of 2019. During the first quarter of 2019, the average molybdenum price decreased by 3.6% when compared to the first quarter of 2018.

31

Table of Contents

Molybdenum is mainly used in the production of special alloys for stainless steel that require significant hardness and corrosion and heat resistance. New uses for this metal are in lubricants, in sulfur filtering of heavy oils and shale gas production, which has seen consumption growth over the past two years. In that sense, we believe that molybdenum prices will continue to remain stable, due to the recovery of the US economy and developed countries.

· Zinc: Represented 4.4% of our sales in the first quarter of 2019. We are aware that the performance of zinc prices over last 12 months has been decreasing, mainly affected by the trade war between US-China, but this effect will be offset in the future by a reduction in supply due to the closure of different zinc mines during recent years.

· Silver: Represented 4.4% of our sales in the first quarter of 2018 and it is currently our third by-product. We believe that silver prices will have support due to its industrial uses as well as its linkage to gold as a value shelter in times of economic uncertainty.

· Production: In the fourth quarter of 2018, we began operations at the new Toquepala concentrator which produced 8,630 tons of copper in 2018. For 2019 we expect to produce 986,700 tons of copper, an 11.7% increase from the 883,689 tons we produced in 2018.

We also expect to produce 21.4 million ounces of silver, about 24% higher than the 2018 production of 17.3 million ounces, mainly resulting from the contribution of the San Martin, Santa Barbara and Toquepala mines. In 2019, we expect to produce 96,400 tons of zinc from our mines, up 36% from 2018 production of 70,778 tons, as a result of the recovery of production at the San Martin mine. Additionally, we expect to produce 25,300 tons of molybdenum, an increase of 15% due to the significant contribution of the molybdenum plant at the new Toquepala concentrator.

· Cost: Our operating costs and expenses for the first quarter 2019 and 2018 were as follows:

|  |  |  |  |  | Variance |
|  | 2019 |  | 2018 |  | Value |  | % |
Operating costs and expenses ($ in millions) |  | $ | 1,059.7 |  | $ | 1,067.8 |  | $ | (8.1 | ) | (0.8 | )%

The decrease was mainly due to lower cost of sales at our Peruvian operations, partially offset by higher depreciation, amortization and depletion at our three operating segments.

· Capital Investments: In the first quarter of 2019 we spent $173.1 million on capital investments, 41.5% lower than in the first quarter of 2018, and represented 44.5% of net income. Our growth program to develop the full production potential of our Company is underway. We are currently developing a new organic growth plan to increase our copper volume production to 1.5 million tons by 2025 with the development of new projects.

KEY MATTERS:

We discuss below several matters that we believe are important to understand our results of operations and financial condition. These matters include, (i) our earnings, (ii) our production, (iii) our “operating cash costs” as a measure of our performance, (iv) metal prices, (v) business segments, (vi) the effect of inflation and other local currency issues, and (vii) our capital investment and exploration program.

Earnings: The table below highlights key financial and operational data of our Company for the three months ended March 31, 2019 and 2018 (in millions, except copper price, percentages and per share amounts):

Copper price LME |  | 2.82 |  | 3.16 |  | (0.34 | ) | (10.8 | )%
Pounds of copper sold |  | 501.4 |  | 469.1 |  | 32.3 |  | 6.9 | %
Net sales |  | $ | 1,753.4 |  | $ | 1,841.1 |  | $ | (87.7 | ) | (4.8 | )%
Operating income |  | $ | 693.7 |  | $ | 773.3 |  | $ | (79.6 | ) | (10.3 | )%
Net income attributable to SCC |  | $ | 388.2 |  | $ | 470.7 |  | $ | (82.5 | ) | (17.5 | )%
Earnings per share |  | $ | 0.50 |  | $ | 0.61 |  | $ | (0.11 | ) | (18.0 | )%
Dividends per share |  | $ | 0.4 |  | $ | 0.30 |  | $ | (0.10 | ) | 33.3 | %

Table of Contents

Net sales in the first quarter of 2019 were 4.8% lower than in the first quarter of 2018 mainly due to lower metal prices, particularly copper (-10.8%, LME). Nevertheless, copper sales volume increased (+6.9%) mainly due to additional production of our new Toquepala concentrator. By-product volumes of silver (+19.9%) and zinc (+2.2%) also increased while molybdenum reduced (-2.7%).

Net income in the first quarter of 2019 was 17.5% lower than in the first quarter of 2018, mainly due to lower sales.

Production: The table below highlights our mine production data for the three months ended March 31, 2019 and 2018:

|  | 2019 |  | 2018 |  | Variance |  | % Change |
Copper (in million pounds) |  | 504.0 |  | 451.5 |  | 52.5 |  | 11.6 | %

Total |  | 504.0 |  | 451.5 |  | 52.5 |  | 11.6 | %

Mined copper production in the first quarter of 2019 increased by 11.6% to 504.0 million pounds compared to 451.5 million pounds in the first quarter of 2018. This increase was due to a higher production at all our operations, specially at our Toquepala mine which benefited from the successful initial ramping up of the new concentrator. Copper production in Mexico increased 5.2%, in the first quarter of 2019 when compared to the same period of 2018 due to operating improvements at our new Buenavista’s plants, SX-EW and concentrator

Molybdenum production slightly decreased 0.6% in the first quarter of 2019 due to lower production at the Toquepala mine as a result of lower grades and recoveries; effect which was partially offset by higher production at the Buenavista and Cuajone mines.

Silver mine production increased by 4.8% in the first quarter of 2019 mainly as result of higher production at Toquepala mine as a result of the expansion project, this was partially offset by lower production at our Cuajone and La Caridad mines.

Zinc production increased 4.6% in the first quarter of 2019, principally due to higher production at the Santa Eulalia mine as a resut of higher milling, as well as higher grades and recoveries.

Operating Cash Costs: An overall benchmark used by us and a common industry metric to measure performance is operating cash costs per pound of copper produced. Operating cash cost is a non-GAAP measure that does not have a standardized meaning and may not be comparable to similarly titled measures provided by other companies. This non-GAAP information should not be considered in isolation or as substitute for measures of performance determined in accordance with GAAP. A reconciliation of our operating cash cost per pound of copper produced to the cost of sales (exclusive of depreciation, amortization and depletion) as presented in the condensed consolidated statement of earnings is presented under the subheading, “Non-GAAP Information Reconciliation” on page 44. We disclose operating cash cost per pound of copper produced, both before and net of by-product revenues.

We define operating cash cost per pound of copper produced before by-product revenues as cost of sales (exclusive of depreciation, amortization and depletion), plus selling, general and administrative charges, treatment and refining charges net of sales premiums; less the cost of purchased concentrates, workers’ participation and other miscellaneous charges, including royalty charges, and the change in inventory levels; divided by total pounds of copper produced by our own mines.

In our calculation of operating cash cost per pound of copper produced, we exclude depreciation, amortization and depletion, which are considered non-cash expenses. Exploration is considered a discretionary expenditure and is also excluded. Workers’ participation provisions are determined on the basis of pre-tax earnings and are also excluded. Additionally excluded from operating cash costs are items of a non-recurring nature and the mining royalty charge as it is based on various calculations of taxable income, depending on which jurisdiction, Peru or Mexico, is imposing the charge. We believe these adjustments will

allow our management and stakeholders to see a presentation of our controllable cash cost, which we consider is one of the lowest of copper producing companies of similar size.

We define operating cash cost per pound of copper produced net of by-product revenues as operating cash cost per pound of copper produced, as defined in the previous paragraph, less by-product revenues and net revenue (loss) on sale of metal purchased from third parties.

In our calculation of operating cash cost per pound of copper produced, net of by-product revenues, we credit against our costs the revenues from the sale of all our by-products, including, molybdenum, zinc, silver, gold, etc. and the net revenue (loss) on sale of metals purchased from third parties. We disclose this measure including the by-product revenues in this way because we consider our principal business to be the production and sale of copper. As part of our copper production process, much of our by-products are recovered. These by-products, as well as the processing of copper purchased from third parties, are a supplemental part of our production process and their sales value contribute to cover part of our incurred fixed costs. We believe that our Company is viewed by the investment community as a copper company, and is valued, in large part, by the investment community’s view of the copper market and our ability to produce copper at a reasonable cost.

We believe that both of these measures are useful tools for our management and our stakeholders. Our cash costs before by-product revenues allow us to monitor our cost structure and address with operating management areas of concern. The measure operating cash cost per pound of copper produced net of by-product revenues is a common measure used in the copper industry and is a useful management tool that allows us to track our performance and better allocate our resources. This measure is also used in our investment project evaluation process to determine a project’s potential contribution to our operations, its competitiveness and its relative strength in different price scenarios. The expected contribution of by-products is generally a significant factor used by the copper industry in determining whether to move forward with the development of a new mining project. As the price of our by-product commodities can have significant fluctuations from period to period, the value of its contribution to our costs can be volatile.

Our operating cash cost per pound of copper produced, before and net of by-product revenues, is presented in the table below for the three months ended March 31, 2019 and 2018:

Operating cash cost per pound of copper produced (1)

(In millions, except cost per pound and percentages)

|  | 2019 |  | 2018 |  | Variance |  | % Change |
Total operating cash cost before by-product revenues |  | $ | 749.4 |  | $ | 688.3 |  | $ | 61.1 |  | 8.9 | %
Total by-products revenues |  | (305.7 | ) | (343.0 | ) | $ | 37.3 |  | (10.9 | )%
Total operating cash cost net of by-products revenues |  | $ | 443.7 |  | $ | 345.3 |  | $ | 98.4 |  | 28.5 | %

By-products per pound revenues |  | $ | (0.62 | ) | $ | (0.78 | ) | $ | 0.16 |  | (20.5 | )%
Operating cash cost per pound net of by-products revenues |  | $ | 0.90 |  | $ | 0.79 |  | $ | 0.11 |  | 13.9 | %

(1) These are non-GAAP measures. Please see page 44 for reconciliation to GAAP measure.

(2) Net of metallurgical losses.

As seen in the table above, our per pound cash cost before by-product revenues in the first quarter of 2019 was 2.5% lower than in the same period of 2018. This decrease in operating cash cost was the result of the unit cost effect of 12.2% higher production.

In addition, our per pound cash cost for the three months ended March 31, 2019 when calculated net of by-product revenues was $0.11 higher than in the first quarter of 2018. This 13.9% increase was mainly the result of lower by-product credits, particularly molybdenum and zinc as well as lower copper purchased from third parties.

Metal Prices: The profitability of our operations is dependent on, and our financial performance is significantly affected by, the international market prices for the products we produce, especially for copper, molybdenum, zinc and silver.

We are subject to market risks arising from the volatility of copper and other metal prices. For the remaining nine months of 2019, assuming that expected metal production and sales are achieved, that tax rates are unchanged and giving no effect to

potential hedging programs, metal price sensitivity factors would indicate the following change in estimated net income attributable to SCC resulting from metal price changes:

|  | Copper |  | Zinc |  | Molybdenum |  | Silver |
Change in metal prices (per pound except silver — per ounce) |  | $ | 0.10 |  | $ | 0.10 |  | $ | 1.00 |  | $ | 1.00 |
Change in net earnings (in millions) |  | $ | 97.2 |  | $ | 10.8 |  | $ | 25.7 |  | $ | 9.4 |

Business Segments: We view our Company as having three reportable segments and manage it on the basis of these segments. These segments are (1) our Peruvian operations, (2) our Mexican open-pit operations and (3) our Mexican underground operations, known as our IMMSA unit. Our Peruvian operations include the Toquepala and Cuajone mine complexes and the smelting and refining plants, industrial railroad and port facilities that service both mines. The Peruvian operations produce copper, with significant by-product production of molybdenum, silver and other material. Our Mexican open-pit operations include La Caridad and Buenavista mine complexes, the smelting and refining plants and support facilities, which service both mines. The Mexican open pit operations produce copper, with significant by-product production of molybdenum, silver and other material. Our IMMSA unit includes five underground mines that produce zinc, lead, copper, silver and gold, a coal mine which produces coal and coke, and several industrial processing facilities for zinc, copper and silver.

Segment information is included in our review of “Results of Operations” in this item and also in Note 10 “Segment and Related Information” of our condensed consolidated financial statements.

Inflation and Exchange Rate Effect of the Peruvian Sol and the Mexican Peso: Our functional currency is the U.S. dollar and our revenues are primarily denominated in U.S. dollars. Significant portions of our operating costs are denominated in Peruvian sol and Mexican pesos. Accordingly, when inflation and currency devaluation/appreciation of the Peruvian currency and Mexican currency occur, our operating results can be affected. In recent years, we do believe such changes have not had a material effect on our results and financial position. Please see Item 3. “Quantitative and Qualitative Disclosures about Market Risk” for more detailed information.

Capital Investment Programs: We made capital investments of $173.1 million in the three months ended March 31, 2019, compared with $295.7 million in the same period of 2018. In general, the capital investments and investment projects described below are intended to increase production, decrease costs or address social and environmental commitments

Set forth below are descriptions of some of our current expected capital investment programs. We expect to meet the cash requirements for these projects from cash on hand, internally generated funds and from additional external financing, including funding received in April 2015. All capital spending plans will continue to be reviewed and adjusted to respond to changes in the economy or market conditions.

Projects in Mexico:

Buenavista Zinc - Sonora: This project is located within the Buenavista facility and includes the development of a new concentrator to produce approximately 80,000 tons of zinc per year which will allow us to double our current zinc production capacity. Also, the project will produce 20,000 tons of additional copper per year. We have completed the basic engineering. Water concessions have been requested. We estimate an investment of $413 million for this project and expect to initiate operations in 2021. This project will generate 3,760 jobs.

Pilares - Sonora: This project, located six kilometers from La Caridad, will be developed as an open-pit mine operation. The ore will be transported from the pit to the primary crushers of the La Caridad copper concentrator through a new 25-meter wide off-road facility for mining trucks, and will significantly improve the over-all mineral ore grade (combining the 0.78% expected from Pilares with the 0.34% from La Caridad). Environmental permit studies were presented to the government’s environmental authorities and additional land is being acquired. An investment of $159 million is estimated to produce 35,000 tons of copper in concentrates per year. We expect this project to start producing in early 2020.

The San Martin mine recovery program. We have continued working on the San Martin mine to initiate operations shortly. Currently, the mine has 200,000 tons of ore and the concentrator has initiated production. For 2019, we expect an annual production of 14,600 tons of zinc, 2.4 million ounces of silver and 5,000 tons of copper. At current market prices, the 2019 production forecast for this unit has an estimated value of $ 108 million. The budget of the recovery program is $87.0 million. At March 31, 2019 the program had a total expense of $34.9 million.

Projects in Peru:

Our main capital projects in Peru are the following:

Toquepala Expansion Project - Tacna: This $1,320 million project includes a new state-of-the-art concentrator which will increase Toquepala’s annual copper production to 258,000 tons in 2019, a 52% production increase, when compared to 2018.

35

Table of Contents

As of March 31, 2019, we have invested $1,240.9 million in this expansion. Construction of the project was completed and production began in the fourth quarter of 2018. Full production is expected to be reached in the second quarter of 2019.

The project to improve the crushing process at Toquepala with the installation of a High Pressure Grinding Roll (HPGR) system, has as its main objective, to ensure that our existing concentrator will operate at its maximum annual production capacity of 117,000 tons of copper while reducing operating costs through ore crushing efficiencies, even with an increase of the ore material hardness index. The budget for this project is $52 million and as of March 31, 2019, we have invested $47 million. We are in the administrative close-out process for this project, which was added to operations during the fourth quarter of 2018.

Cuajone tailing thickeners project - Moquegua: This project will replace two of the three existing thickeners at the concentrator with a new hi-rate thickener. The purpose is to streamline the concentrator flotation process and improve water recovery efficiency, increasing the tailings solids content from 54% to 61%, thereby reducing fresh water consumption and replacing it with recovered water. Equipment assembly is completed and we are in the commissioning process. As of March 31, 2019, we have invested the full approved budget of $31 million in this project. During the commissioning process, a problem in the design of the thickener was detected and we are currently solving the problem. We expect the project to be completed in the second quarter of 2019.

Tailings disposal at Quebrada Honda - Moquegua: This project increases the height of the existing Quebrada Honda dam to impound future tailings from the Toquepala and Cuajone mills and will extend the expected life of this tailings facility by 25 years. The first stage and construction of the drainage system for the lateral dam is finished. We finished the second stage with the installation of a new cyclone battery station that allows us to place more slurry at the dams. We are working to improve several operational processes of this facility. The project has a total budgeted cost of $116 million. We have invested $103 million through March 31, 2019 and expect the project to be completed in the second quarter of 2019.

Potential projects

We have a number of other projects that we may develop in the future. We evaluate new projects on the basis of our long-term corporate objectives, expected return on investment, environmental concerns, required investment and estimated production, among other considerations. All capital spending plans will continue to be reviewed and adjusted to respond to changes in the economy or market conditions.

El Arco - Baja California: This is a world class copper deposit located in the central part of the Baja California peninsula, with ore reserves of over 2.7 billion tons with an ore grade of 0.399% and 0.11 grams of gold per ton. This project, includes an open-pit mine combining concentrator and SX-EW operations with an estimated production of 190,000 tons of copper and 105,000 ounces of gold annually. Between July 2015 and February 2016, we conducted a drilling program of 20,170 meters in order to further define the deposit at lower depths of between 300 and 600 meters.

El Pilar - Sonora: This is a fully permitted, low capital intensity copper development project strategically located in Sonora, Mexico, approximately 45 kilometers from our Buenavista mine. Its copper oxide mineralization contains estimated proven and probable reserves of 325 million tons of ore with an average copper grade of 0.287%. El Pilar will operate as a conventional open-pit mine and copper cathodes will be produced using the highly cost efficient and environmentally friendly SX-EW technology. Average annual production is currently estimated at 35,000 tons of copper cathodes over an initial 13-year mine life. On a preliminary basis, we estimate a development investment of approximately $310 million. During 2018 we continued with the metallurgical testing program, as well as with social development work with local communities. We are also concluding a preliminary economic study of the project.

Tia Maria - Arequipa: We completed all engineering and environmental requirements, including responding to the 14 observations received from the Ministry of Energy and Mines in the fourth quarter of 2018. We are working jointly with the Peruvian government to obtain the construction license for this 120,000 tons of SX-EW copper per year greenfield project with a total capital budget of $1,400 million. We expect to receive the construction license for this project in the first half of 2019. However, there can be no assurance that the permit will be issued. Future delay in obtaining the permit or opposition to the project could materially impact the mine’s expansion plans.

In addition to our on-going social work with the communities of the Tambo valley, the Company is currently deploying its successful labor program “Forge Your Future” (Forjando Futuro) to train 700 people from the Islay Province in 2019. After training, the participants will be eligible to apply for one of the estimated 9,000 jobs (3,600 direct and 5,400 indirect) required during the Tia Maria construction phase. We believe that the initiation of construction activities for Tia Maria will generate significant economic opportunities for the Islay province and the Arequipa region.

This greenfield project, located in Arequipa, Peru, will use state of the art SX-EW technology with the highest international environmental standards. SX-EW facilities are the most environmentally friendly in the industry due to their technical process with no emissions released into the atmosphere. The project will use seawater, transporting it more than 25 kilometers to an altitude of 1,000 meters above sea level. The construction of the desalinization plant requires an investment of approximately $95 million.

Los Chancas - Apurimac: This greenfield project, located in Apurimac, Peru, is a copper and molybdenum porphyry deposit. Current estimates indicate the presence of 545 million tons of mineralized material with a copper content of 0.59%, molybdenum content of 0.04% and 0.039 grams of gold per ton, as well as 181 million tons of mineralized leachable material with a total copper content of 0.357%. Los Chancas project envisions an open-pit mine with a combined operation of concentrator and SX-EW processes to annually produce 130,000 tons of copper and 7,500 tons of molybdenum. The estimated capital investment is $2,800 million and is expected to be in operation in 2025. In 2018, we continued with the development of social and environmental improvements for the local communities. We plan to complete the environmental impact assessment in 2020.

Michiquillay Project - Cajamarca: On June 12, 2018, Southern Copper signed a contract and made an initial payment of $12.5 million for the acquisition of the Michiquillay project in Cajamarca, Peru. The Company has created a multidisciplinary management team to plan the development of this project. As part of this plan, the Company has established contact with the local authorities and communities in order to promote programs for the sustainable development of the area. In February 2019, the Company began preliminary social and technical work in the area of the project.

Michiquillay is a world class mining project with estimated mineralized material of 1,150 million tons with an estimated copper grade of 0.63%. When developed, we expect Michiquillay to produce 225,000 tons of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years, at a competitive cash-cost. We estimate an investment of approximately $2.5 billion will be required and expect production start-up by 2025, with Michiquillay becoming one of Peru´s largest copper mines. The project will create significant business opportunities in the Cajamarca region, generate new jobs for the local communities and contribute with taxes and royalties to the national, regional and local governments.

The above information is based on estimates only. We cannot make any assurances that we will undertake any of these projects or that the information noted is accurate.

ACCOUNTING ESTIMATES

Our discussion and analysis of financial condition and results of operations, as well as quantitative and qualitative disclosures about market risks, are based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. Preparation of these consolidated financial statements requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We make our best estimate of the ultimate outcome for these items based on historical trends and other information available when the financial statements are prepared. Changes in estimates are recognized in accordance with the accounting rules for the estimate, which is typically in the period when new information becomes available to management. Areas where the nature of the estimate makes it reasonably possible that actual results could materially differ from amounts estimated include: ore reserves, revenue recognition, ore stockpiles on leach pads and related amortization, estimated impairment of assets, asset retirement obligations, determination of discount rates related to the financial lease liabilities, classification of operating leases versus financial leases, valuation allowances for deferred tax assets, unrecognized tax benefits and fair value of financial instruments. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

In addition, the Mexican royalty, the Peruvian royalty and the Peruvian special mining tax are included in the income tax provision. The increase in the effective tax rate for the first quarter of 2019 from the same period in the prior year is primarily due to the movement in exchange gain or loss from the appreciation in 2019 of the Mexican peso versus the U.S. dollar measured against the devaluation of the Mexican peso in the same period of 2018, and a SAB 118 adjustment to the valuation allowance in the first quarter of 2018, which is not applicable for the first quarter of 2019.

Operating income |  | $ | 144.7 |  | $ | 189.3 |  | $ | (44.6 | ) | (23.6 | )%

Net Sales in the first quarter of 2019 were $580.1 million compared to $642.9 million in the first quarter of 2018. The decrease in net sales was mainly the result of lower copper and molybdenum prices, as well as lower molybdenum sales volume (-28.9%). However, this effect was partially offset by higher copper (+7.3%) and silver (+22.2%) sales volumes.

Operating costs and expenses in the first quarter of 2019 decreased by $18.2 million to $435.4 million from $453.6 million in the first quarter of 2018, primarily due to:

Operating cost and expenses for the first quarter 2018 |  | $ | 453.6 |
Less: |  |  |
· Lower volume and cost of metals purchased from third parties. |  | (84.3 | )

Table of Contents

Net Sales in the first quarter of 2019 were $1,072.1 million, compared to $1,068.6 million in the first quarter of 2018. The increase of $3.5 million was principally due to higher copper, silver and molybdenum sales volumes, partially offset by lower copper and silver prices.

Operating costs and expenses in the first quarter of 2019 increased by $5.0 million to $521.3 million from $516.3 million in the same 2018 period, primarily due to:

Operating cost and expenses for the first quarter 2018 |  | $ | 516.3 |
Plus: |  |  |
· Higher cost of sales (exclusive of depreciation, amortization and depletion) mainly due to higher inventory consumption and lower capitalized leachable material, partially offset by lower cost of metals purchased from third parties, and foreign currency effect. |  | 8.3 |

Operating income |  | $ | 4.4 |  | $ | 38.9 |  | $ | (34.5 | ) | (88.7 | )%

Net Sales in the first quarter of 2019 were $121.1 million, compared to $149.2 million in the first quarter of 2018. This decrease of $28.1 million was primarily due to lower metal prices.

Operating costs and expenses in the first quarter of 2019 increased by $6.4 million to $116.7 million from $110.3 million in the first quarter of 2018, primarily due to:

Operating cost and expenses for the first quarter 2018 |  | $ | 110.3 |
Plus: |  |  |
· Higher cost of sales (exclusive of depreciation, amortization and depletion) mainly due to higher power and operating contractors costs, partially offset by lower inventory consumption. |  | 4.4 |

Item 3. Quantitative and Qualitative Disclosure about Market Risk

Commodity price risk:

For additional information on metal price sensitivity, refer to “Metal Prices” in Part I, Item 2 of this quarterly report on Form 10-Q for the period ended March 31, 2019.

Foreign currency exchange rate risk:

Our functional currency is the U.S. dollar. Portions of our operating costs are denominated in Peruvian soles and Mexican pesos. Since our revenues are primarily denominated in U.S. dollars, when inflation or deflation in our Mexican or Peruvian operations is not offset by a change in the exchange rate of the sol or the peso to the dollar, our financial position, results of operations and cash flows could be affected by local cost conversion when expressed in U.S. dollars. In addition, the dollar value of our net monetary

44

Table of Contents

assets denominated in soles or pesos can be affected by exchange rate variances of the sol or the peso, resulting in a re-measurement gain or loss in our financial statements. Recent inflation and exchange rate variances are provided in the table below for the three months ended March 31, 2019 and 2018:

|  | 2019 |  | 2018 |
Peru: |  |  |  |  |
Peruvian inflation rate |  | 0.88 | % | 0.97 | %
Initial exchange rate |  | 3.379 |  | 3.245 |
Closing exchange rate |  | 3.321 |  | 3.229 |
Appreciation/(devaluation) |  | 1.72 | % | 0.49 | %
Mexico: |  |  |  |  |
Mexican inflation rate |  | 0.44 | % | 1.24 | %
Initial exchange rate |  | 19.683 |  | 19.735 |
Closing exchange rate |  | 19.379 |  | 18.345 |
Appreciation/(devaluation) |  | 1.54 | % | 7.05 | %

Change in monetary position:

Assuming an exchange rate variance of 10% at March 31, 2019 we estimate our net monetary position in Peruvian sol and Mexican peso would increase (decrease) our net earnings as follows:

|  | Effect on net earnings |
|  | ($ in millions) |
Appreciation of 10% in U.S. dollar vs. Peruvian sol |  | $ | 16.6 |
Devaluation of 10% in U.S. dollar vs. Peruvian sol |  | $ | (20.3 | )
Appreciation of 10% in U.S. dollar vs. Mexican peso |  | $ | 10.5 |
Devaluation of 10% in U.S. dollar vs. Mexican peso |  | $ | (12.8 | )

Open sales risk:

Our provisional copper and molybdenum sales contain an embedded derivative that is required to be separate from the host contract for accounting purposes. The host contract is the receivable from the sale of copper and molybdenum concentrates at prevailing market prices at the time of the sale. The embedded derivative, which does not qualify for hedge accounting, is marked to market through earnings each period prior to settlement. See Note 5 to our condensed consolidated financial statements for further information about these provisional sales.

Short-term Investments:

For additional information on our trading securities and available-for-sale investments, refer to “Short-term Investments” in Part I, Item 1 of this quarterly report on Form 10-Q for the period ended March 31, 2019.

Cautionary Statement:

Forward-looking statements in this report and in other Company statements 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 as well as projected demand or supply for the Company’s products. Actual results could differ materially depending upon factors including 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 as well as political and economic risk associated with foreign operations. Results of operations are directly affected by metal prices on commodity exchanges that can be volatile.

Item 4. Controls and Procedures

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

As of March 31, 2019, the Company conducted an evaluation under the supervision and with the participation of the Company’s disclosure committee and the Company’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness and the design and operation of the Company’s disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)). Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are effective as of March 31, 2019, to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is:

1. Recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and

2. Accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

Beginning January 1, 2019, the Company adopted ASC 842, Leases. In relation to this, the Company implemented changes to its internal controls related to lease accounting. These changes included performing a comprehensive lease scoping analysis to identify, disaggregate and evaluate each of the Company’s lease categories and implementing a model to calculate right-of-use assets and lease liabilities values for the Company’s leases. There were no other changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended) that occurred during the first quarter ended March 31, 2019 that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Southern Copper Corporation:

Results of Review of Interim Financial Statements

We have reviewed the accompanying condensed consolidated balance sheet of Southern Copper Corporation and subsidiaries (the “Company”) as of March 31, 2019, the related condensed consolidated statements of earnings, comprehensive income and cash flows for the three-month periods ended March 31, 2019 and 2018, and the related notes (collectively referred to as the “interim financial information”). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2018, and the related consolidated statements of earnings, comprehensive income, and cash flows for the year then ended (not presented herein); and in our report dated March 1, 2019, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2018 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

This interim financial information is the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our reviews in accordance with standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the condensed consolidated interim financial statements taken as a whole. Accordingly, we do not express such an opinion.

Item 2. Unregistered Sale of Equity Securities and Use of Proceeds:

SCC share repurchase program:

In 2008, the Company’s BOD authorized a $500 million share repurchase program that has since been increased by the BOD and is currently authorized to $3 billion. Pursuant to this program, the Company has purchased 119.5 million shares of common stock at a cost of $2.9 billion. These shares are available for general corporate purposes. The Company may purchase additional shares of its common stock from time to time, based on market conditions and other factors. This repurchase program has no expiration date and may be modified or discontinued at any time.

The NYSE closing price of SCC common shares at March 31, 2019 was $39.68 and the maximum number of shares that the Company could purchase at that price is 2.1 million shares.

As a result of the repurchase of shares of SCC’s common stock, Grupo Mexico’s direct and indirect ownership was 88.9% as of March 31, 2019. There has not been any activity in the SCC share repurchase program since the third quarter of 2016.
