NOTE 6 — DERIVATIVE INSTRUMENTS:

From time to time, the Company uses derivative instruments to manage its cash flows exposure to changes in commodity prices. The Company does not enter into derivative contracts unless it anticipates that the possibility exists that future activity will expose the Company’s future cash flows to deterioration. Derivative contracts for commodities are entered into to manage the price risk associated with forecasted purchases of the commodities that the Company uses in its manufacturing process.

Cash Flow Hedges of Natural Gas

The Company’s objective in using natural gas derivatives was to protect the stability of natural gas costs and manage exposure to natural gas price increases. To protect natural gas costs from estimated price increases in 2021, the Company acquired two derivative instruments that began in November 2021 and ended in March 2022.

The Company assessed these derivative instruments as Cash Flow Hedges. As such, the effective portions of said hedges were initially reported in Other Comprehensive Income (OCI) and were reclassified as earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affected earnings. The Company did not identify any ineffective portions of these derivatives.

As of March 31, 2023, the Company did not hold derivative instruments.

NOTE 7 — LEASES:

The Company has operating leases for power generating facilities, vehicles and properties. The Company recognizes leasing expenses 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 one year to 10 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 have no material residual value guarantees or material restrictive covenants. As none of the Company’s leases stipulates 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 eight years, and the weighted average discount rate for these leases is 3.81%.

The operating lease expense recognized in the first three months of 2023 and 2022 was classified as follows (in millions):


Classification	2023		2022
Cost of sales (exclusive of depreciation, amortization and depletion)	$	29.1	$	28.8

NOTE 8 — ASSET RETIREMENT OBLIGATION:

Peruvian operations:

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.

On June 24, 2019, MINEM approved a change to the guarantees required for the mining closure plans. The new regulation specifies that annual guarantees can be secured with real estate up to a maximum of 50% and the remaining amount with credit instruments. Currently, the Company has pledged the value of its Lima office complex for the 50% of the guarantee and with a stand-by letter of credit for the other 50% as a security for this obligation. Through January 2023, the Company has provided total guarantees of $77.1 million.

On July 20, 2021, the Peruvian Government published Law 31347, which requires companies in the production stage to set aside additional guarantees for progressive closure of its operations. The resources that back these guarantees will be returned to the Company when activities cease and the regulatory agency verifies that all closure measures have been satisfactorily completed. Under this Law, companies must include activities for environmental remediation within the closure schedule and assume costs associated with environmental impacts that are identified during audits. As of March 31, 2023, the regulation attached to this Law had yet to be published. The Company is currently evaluating the possible financial impact of the Law but cannot fully estimate the magnitude until the Law’s regulation is published.

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 and the revised closure plans for the Cuajone mine and the Ilo facilities were approved in January and October 2019, respectively. As a result of these new estimates, the Company increased the asset retirement obligation by $28.1 million in 2019. The closure plan for the Tia Maria project was approved in February 2017. The Company, however, has not recorded a retirement obligation for the project because the work on the project is on hold. The Company believes that under these circumstances, the recording of a retirement obligation is not appropriate.

In 2022, the Company made a change in the estimate for the asset retirement obligation for its Peruvian operations, mainly due to a detailed review of the closing activities required for each facility. The effect of this change was a decrease in the asset retirement liability by $59.5 million, which was recorded in December 2022, reducing the asset retirement asset by $43.3 million and the difference of $16.2 million was recorded as a reduction in cost of goods sold.

Mexican operations:

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.

In the first quarter of 2022, the Company adjusted its estimate for the asset retirement obligation for its Mexican operations following a detailed review of the closing activities required. The effect was an increase in the asset retirement obligation to the order of $43.3 million.

The following table summarizes the asset retirement obligation activity for the first three months of 2023 and 2022 (in millions):

NOTE 10 — COMMITMENTS AND CONTINGENCIES:

Environmental matters:

The Company has established comprehensive environmental conservation programs at its mining facilities in Peru and Mexico, which include water recovery systems to conserve water and minimize the impact on nearby streams, reforestation programs to stabilize the surface of the tailings dams and the implementation of scrubbing technology in the mines to reduce dust emissions, among others.

Environmental capital investments in the first quarter of 2023 and 2022 were as follows (in millions):


	2023		2022
Peruvian operations	$	2.7	$	1.4
Mexican operations		23.2		12.6
	$	25.9	$	14.0

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 relating to environmental and legal compliance, 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 8 “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. As of March 31, 2023, the Company maintains a daily average level of µg/m3 of SO2, which falls below the requirement under the AQS.

Soil Environmental Quality Standards (“SQS”): In 2013, the Peruvian government enacted Soil Quality Standards. In accordance with the regulatory requirements of the law, the Company prepared Soil Decontamination Plans (“SDP”) for environmentally impacted sites at each of its operation units (Toquepala, Cuajone and Ilo) with the assistance of consulting companies. The costs of these SDPs are not material, either individually or in aggregated form, for the financial statements of the Company.

Climate change: On April 17, 2018, the Peruvian government enacted Law N. 30754, which promulgates that it is in the national interest to promote public and private investments in climate change management and establishes a Climate Change Framework. The law proposes creating an institutional framework to address climate change in Peru and outlines new measures for climate change mitigation, such as provisions to address an increase in carbon capture and use of carbon sinks; afforestation and reforestation practices; land use changes; sustainable systems of transportation, solid waste management, and energy systems. This climate change framework law incorporates obligations from the Paris Agreement. Supreme Decree 013-2019 published on December 31, 2019, enacted statutory regulations, which are applicable to all Peruvian institutions and agencies. It is expected that additional Peruvian regulations will be applicable to non-governmental entities. However, no carbon pricing mechanism is currently applicable to the Company’s operations in Peru.

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

Table of Contents

that violate environmental laws, which in the most extreme cases may result in the temporary or permanent shutdown of operations, the revocation of operating licenses and/or other sanctions or fines.

In 2011, the General Law was amended to provide 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. Additionally, amendments to the Civil Federal Procedures Code (“CFPC”) were enacted in 2011 and established three categories of collective actions under which a group of 30 or more individuals can be considered sufficient to prove a “legitimate interest” to file civil actions for injuries arising out of alleged violations of environmental, consumer protection, financial services and Antitrust laws. The group can seek restitution or economic compensation for the alleged injuries or suspension of the activities which allegedly caused the injuries in question. 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 considered likely to cause environmental harm. If a possible determination regarding harm occurs, environmental clean-up and remedial actions sufficient to restore the environment to a pre-existing condition must be taken. If restoration is not possible, compensation measures should be provided. Criminal penalties and monetary fines can be imposed under this law.

In February 2019, the Mexican Supreme Court confirmed the constitutionality of an ecological tax on extractive activities carried out in the state of Zacatecas, which taxes the environmental remediation actions; emissions of certain gases to the atmosphere; emissions of polluting substances to the soil or water; and waste storage within the state. The Company has determined that this environmental regulation will have no impact on its financial position.

Guaymas sulfuric acid spill: On July 9, 2019, there was an incident at the Company´s Marine Terminal in Guaymas, Sonora, that caused the discharge of approximately three cubic meters of sulfuric acid into the sea in the industrial port area.

The Guaymas bay has an estimated water volume of 340 million cubic meters. The spill, upon entering in contact with the sea’s alkaline conditions, led to quick dilution of the discharge. Thus, the sulfuric acid was naturally and immediately neutralized. As a result, the discharge was considered harmless; the report from the Ministry of Navy found that neither the flora nor fauna of the port area were affected.

On July 10, 2019, PROFEPA made a first inspection of the area, concluding that the Company executed all the appropriate procedures to contain the discharge, and no reference was made to the existence of negative impacts on the environment resulting from the incident. On July 19, 2019, PROFEPA revisited the facilities to carry out a second inspection and declared a partial temporary shutdown that only affected the storage process and transportation of sulfuric acid at the terminal, arguing the absence of an authorization of environmental impact. It is important to note that these facilities have been in operation since 1979, prior to the 1988 Mexican General Law of Ecological Balance and the Protection of the Environment. Companies that were operating before the enactment of the aforementioned law are exempt from the permit requirement. In addition, in 2009, PROFEPA awarded a certification of “Clean Industry and Environmental Quality” to the facility which was subsequently renewed four times (for a two-year period each time).

The Company filed a lawsuit against the closure, which was dismissed by a ruling on August 25, 2021. This ruling has been challenged through a motion to reopen the case, which was submitted on September 28, 2021. On January 4, 2022, the challenge was resolved. The authority imposed two fines and ruled that the temporary closure would remain in place until the environmental impact statement is obtained. The Company intends to appeal this ruling.

The Company is not aware of the reasons or causes for this partial and temporary closure, but will continue working with the environmental authorities to provide certainty that the operation is in strict compliance with environmental regulations. The Company expects the environmental authorities to suspend the partial temporary shutdown, once they resolve their concerns. Currently, the Company does not expect any impact on its operations. As of March 31, 2023, the matter is pending resolution.

Climate change: Several taxes are applicable to the Company’s mining operations in Mexico, including federal and state fossil fuel taxes, and the requirements associated with Mexico’s emission trading scheme. These taxes range from $1.2/tCO2 to $20/tCO2, approximately. These regional taxes are applicable in the States of Baja California and Zacatecas, as well as a federal tax linked to the import of fuels. In addition, an emission trading scheme (ETS) is currently available to the Company which is currently only applicable to two business units, the metallurgic and lime plants in Sonora, which both generate annual GHG emissions levels above the threshold of 100,000 tCO2e per year contemplated by the scheme. These two units are required to report and verify their emissions once a year with average costs of less than $6,000 per unit. Units that emit more than 25,000 tonnes CO2 equivalent per year (all our Mexican units) are required to report their emissions to the National Emissions Registry (RENE) every year and to verify the reported emissions every three years. As a result, the total expenses for ensure annual compliance with climate change regulations in Mexico were not material to the Company.

The Company believes that all of its facilities in Peru and Mexico are in material compliance with environmental, mining and other applicable laws and regulations. The Company also believes that continued compliance with environmental laws of Mexico and Peru will have no material adverse effects on the Company’s business, properties, or operating results.

Litigation matters:

Peruvian operations:

The Tia Maria Mining Project

There are five 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 that approved the Environmental Impact Assessment of the project; (ii) the cancellation of the project and the withdrawal of mining activities in the area; (iii) to annul the mining

concession application for the Tia Maria project; and (iv) to annul the resolution that approved the construction license. The lawsuits were filed by Messrs. Ernesto Mendoza Padilla (filed May 26, 2015), Juan Alberto Guillen Lopez (filed June 18, 2015), Junta de Usuarios del Valle del Tambo (filed April 30, 2015), Gobierno Regional de Arequipa (filed December 16, 2019) and Municipalidad Distrital de Dean Valdivia (filed in January 2020 but notified in August 2022).

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. On November 20, 2018, the Constitutional Court reversed the previous decisions and remanded the case to the lower court for further action. In the third quarter of 2020, the Company was notified that the complaint had been reinstated. The Company answered the complaint on September 15, 2020. On December 2, 2020, the lower court issued a resolution, considering the complaint answered. On September 27, 2021, the Court ordered to temporarily archive the case. As of March 31, 2023, the case remains pending resolution.

The Guillen Lopez case is currently before the lower court. Oral arguments took place on July 19, 2019. On January 7, 2020, the Judge decided to suspend the proceeding until the del Carpio Lazo case is concluded. On March 8, 2022, SCC’s Peruvian Branch informed the Court that the del Carpio Lazo case had concluded. As of March 31, 2023, the case remains pending resolution.

The Junta de Usuarios del Valle del Tambo case is currently before the lower court. In May 2016, the Company was included in the process, after the Ministry of Energy and Mines filed a civil complaint. On March 6, 2019, the Company was formally notified of the lawsuit and answered the complaint on March 20, 2019. On July 8, 2019, the Company requested the suspension of the proceeding until the del Carpio Lazo case is concluded. On March 11, 2022, SCC’s Peruvian Branch informed the Court that the del Carpio Lazo case had concluded. As of March 31, 2023, the case remains pending resolution.

The Gobierno Regional de Arequipa case is currently before the lower court. The Company answered the complaint on September 15, 2020. On February 8, 2021, the Judge decided to suspend the proceeding until the del Carpio Lazo case was concluded. On March 24, 2022, SCC’s Peruvian Branch informed the Court that the del Carpio Lazo case had

concluded. On March 28, 2022, the Judge cancelled the suspension. On May 24, 2022, the parties presented their closing arguments. On March 15, 2023, the Judge dismissed the lawsuit. The plaintiff missed the chance to appeal the ruling, therefore, the case has concluded in favor of SCC’s Peruvian Branch.

The Municipalidad Distrital de Dean Valdivia case is currently before the lower court. On August 17, 2022, the Company was formally notified of the lawsuit and answered the complaint on September 2, 2022. As of March 31, 2023, the case is pending resolution.

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, since 1995, constructed and operated the tailings dams with proper governmental authorization. Following a motion filed by the Peruvian Branch, the lower court included MINEM as a defendant in this lawsuit. MINEM has answered the complaint and denied the validity of the claim. On July 2, 2022, the case was temporarily archived. As of March 31, 2023, the case is pending resolution.

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 at a leaching pond in 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 to determine those responsible for environmental damages. During the second quarter of 2018, the criminal complaint was dismissed. This decision was appealed and was pending resolution as of March 31, 2023.

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. Three of the collective action lawsuits have been dismissed by the court. As of March 31, 2023, three lawsuits are still pending: two were filed by Acciones Colectivas de Sinaloa, A.C. and one by Defensa Colectiva, A.C., seeking precautionary measures in the construction of facilities to monitoring public health services and prohibiting the closure of the Rio Sonora Trust.

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 Dominguez 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;

In 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. In the last quarter of 2018, BVC was served with other three civil action lawsuits, claiming similar damages. These lawsuits were filed by Los Corrales de la Estancia, S.C. de R.L.; Jose Antonio Navarro; Jesus Maria Peña Molina, et al; these actions were dismissed by the court, because they have expired. As of March 31, 2023, forty-five cases remain pending resolution.

In 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 to the spill in August 2014. The plaintiffs in these lawsuits are: Francisca Garcia Enriquez, et al filed two lawsuits, Francisco Ramon Miranda, et al and Jesus David Lopez Peralta et al. In 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. In 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. With regard to 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 establishing 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. This public meeting will have no material effects to BVC’s operations. SEMARNAT has carried out the consultation ordered by the Supreme Court. As a result, it has informed the corresponding Judge its compliance with the resolution, in which BVC was required to implement additional measures of environmental impact prevention, such as: (i) the building of at least three monitoring wells downstream from the curtain of the contingency dam in a period of six months; (ii) monitoring of the groundwater level and water quality every six months; (iii) carrying out rain collection work in order to restore water to the Sonora River basin, with six months granted to present the execution program; (iv) determine the location of wildlife conservation and protection areas and define the need to establish biological corridors; (v) obtain photographic or videographic evidence every six months; (vi) submitting to SEMARNAT two years before the closure and abandonment of the site, or earlier if necessary, the closure program that includes the cleaning and restoration of the soil including Mexican regulation NOM-141; (vii) include the measures in the Environmental Monitoring Program according to the environmental components impacted; and (viii) hiring an external environmental consultant to validate compliance with the current and new conditions imposed. The foregoing does not impact BVC’s operations. Additionally, the lawsuits filed by Maria de los Angeles Enriquez Bacame and Norberto Bustamante have been dismissed and closed without prejudice to the Company. As of March 31, 2023, the remaining cases were still pending resolution.

It is currently not possible to determine the extent of the damages sought in these state and federal lawsuits but the Company believes that these lawsuits are without merit. Accordingly, the Company is vigorously defending against them. Nevertheless, the Company believes 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.

Labor matters:

Peruvian operations: 69.6% of the Company's 4,509 Peruvian employees were unionized at March 31, 2023. Currently, there are six separate unions, none of which represents the majority of workers, as defined by current Peruvian labor legislation.

During 2021, the Company held talks with the six unions to sign collective agreements prior to their effective dates. As a result, between the duration of the agreement. A long-term agreement bonus of S/10,000 (approximately $2,656) was granted to June and December 2021, the Company signed collective agreements with the six unions with durations between three to six years. All of them granted annual salary increases of 5%. Additionally, each agreement granted, among other things, a signing bonus of between S/45,000 (approximately $11,952) and S/90,000 (approximately $23,904), depending on the union that signed a six-year extension of the collective bargaining agreement. All these concepts were recorded as labor expense. In 2022, these collective agreements were executed and the Company does not have any collective agreement pending to be negotiated with the unions.

In December 2022, the Company reached a settlement with one of the unions regarding compliance with an 2018-2019 Arbitration Award. As part of this settlement, the Company made a one-time payment to each union member of S/4,000 (approximately $1,062) as a compensation bonus and also paid a signing bonus of S/1,000 (approximately $265.6).

In the first quarter of 2023, the Company began applying the terms of the agreement entered into with the six unions pursuant to Law 31632, which stipulates new conditions for compensation of leaves granted during COVID-19. These conditions will be in effect until December 1, 2023.

Mexican operations: In recent years, the Mexican operations have experienced a positive improvement in their labor environment, as 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 would hold the collective bargaining agreement at the San Martin 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 Martin mine. Such authorization was challenged by the National Mining Union. On April 4, 2019, the Federal Mediation and Arbitration Board recognized, once again, the election results from February 28, 2018, by which the National Federation of Independent Unions won by a majority. In the last quarter of 2019, a Federal Court issued a resolution that established that the Labor Court should analyze the list of workers with the right to vote in the union election. The Company and the National Federation of Independent Unions challenged such determination before the Supreme Court of Justice. Such challenges were dismissed by the Supreme Court. As a consequence, on September 6, 2021, the Federal Mediation and Arbitration Board issued a new resolution determining that, based on the documents submitted by the National Federation of Independent Unions and given the status of the strike until 2018, it was not possible to create a registry of workers holding a right to vote. Therefore, in case of a strike, any collective bargaining proceedings shall remain suspended. The Federal Mediation and Arbitration Board shall decide on the request of the majority of workers to end the strike, despite the opposition of the National Mining Union. The Company expects that the conflict will be solved in accordance with the legal framework set by labor authorities and that any actions taken will respect the workers’ will.

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, 2023, the case was 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:

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 inferred mineral resources of 2,288 million tonnes with an estimated copper grade of 0.43%. It is expected to produce 225,000 tonnes of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years.

As per the purchase agreement, the Company paid $12.5 million at the signing of the contract and $12.5 million in June 2021. The remaining balance of $375.0 million will be paid if the Company decides to develop the project. Therefore, it is not a present obligation. In June 2022, the Company notified the Peruvian authorities the end of the suspension period and the start of the pre-operational period that lasts 12 years and it can be extended for three more years. The start of the pre-operational period does not imply a payment obligation. The Company must support an investment of $20 million in the next five years which includes exploration activities as well as the development of social programs.

In 2021, the Company signed social agreements with the Michiquillay and La Encañada communities. In addition, in October 2021, the Peruvian Ministry of Energy and Mines approved the semi-detailed environmental impact study for the project. In the last quarter of 2022, the Company informed MINEM that exploration activities had begun and that it initiated an assessment of existing mineral resources at depth. In 2023, in accordance with the social agreements with the Michiquillay and La Encañada communities, the Company has hired unskilled labor and is paying for the use of surface land. The Company is supporting social programs in both communities as it rolls out exploration activities.

Social agreements with the Michiquillay and La Encañada communities represent an opportunity to improve quality of life of their residents through the Company´s strong social programs, backed by a solid framework for technical work at the project level. The main commitments signed by the Company in the social agreements are related to providing support for agricultural and livestock activities, financial support for local initiatives, and social programs in favor of education, water management, waste disposal, and healthcare for vulnerable groups.

Corporate Social Responsibility

The Company has a corporate social responsibility policy to maintain and promote the continuity of its mining operations while obtaining the best results. The main objective of this policy is to integrate the Company´s operations with local communities in the areas of influence of its operations by creating permanent positive relationships to develop optimum social conditions and 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 $118.2 million). In relation to this commitment, the Company has completed the construction of a school with an investment of S/18.8 million (approximately $5.0 million), has co-financed the construction of the Cularjahuira dam for S/15.6 million (approximately $4.1 million) and is preparing the engineering study for the Callazas dam for S/2.6 million (approximately $0.7 million). Additionally, in relation to the S/445.0 million, the Company has committed S/10.7 million (approximately $2.8 million) for six terrace fields projects and S/4.2 million (approximately $1.1 million) for irrigation systems projects.

As the Toquepala expansion project was completed, the Company considers that these commitments constitute present obligations of the Company and consequently has recorded a liability of $31.3 million in its condensed consolidated financial statements as of March 31, 2023.

In addition, the Company has committed S/97.7 million (approximately $26.0 million) for the construction of a high-achievement school in the Tacna 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.

Moquegua Region: In the Moquegua region, the Company participates in a “development roundtable” with local municipal authorities and community representatives to discuss social needs and to determine the ways that the Company can contribute to sustainable development in the region. Although the development roundtable is not currently meeting, it was previously discussing the creation of a Moquegua Region Development Fund, for which the Company has offered a contribution of S/1,000 million (approximately $265.6 million). While final funding is not yet settled, the Company has committed to contribute S/108.4 million (approximately $28.8 million) as an advance, which was utilized to fund an educational project. In addition, there is a commitment to finance the construction of a residual water treatment plant in Ilo for S/105.5 million (approximately $28.0 million). There was also a commitment to build three schools in Moquegua for S/18.2 million (approximately $4.8 million) and to build tracks and sidewalks in Pacocha for S/6.4 million (approximately $1.7 million), which have been completed.

In addition, the Company has committed S/152.3 million (approximately $40.5 million) to build four 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.

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 set at 38.44 Mexican pesos (approximately $2.63) for the initial subscription. 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.

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.

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, which 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, 2023 and December 31, 2022 (in millions):


	At March 31, 2023				At December 31, 2022
	Carrying Value		Fair Value		Carrying Value		Fair Value
Liabilities:
Long-term debt level 1		6,200.8		6,384.2		6,200.0	$	6,372.6
Long-term debt level 2		51.2		56.5		51.2		54.2
Total long-term debt	$	6,252.0	$	6,440.7	$	6,251.2	$	6,426.8

Table of Contents

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 case of the Yankee bonds, which qualify as Level 2 in the fair value hierarchy as they are based on quoted prices in markets 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, 2023 and December 31, 2022 (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 are 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.

Table of Contents

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 Platts Metals Week and are considered Level 1 in the fair value hierarchy.

In addition, in the third quarter of 2021, the Company acquired two derivative instruments to protect natural gas costs from estimated price increases in the previous winter season. These derivative instruments occupied November 2021 through March 2022 period. For further information please refer to Note 6 “Derivative instruments.”

NOTE 14 — 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, types 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 types 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 the Chief Operating Decision Maker (“CODM”) on the segment basis. The CODM of the

Table of Contents

Company focuses 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.

NOTE 15 — SUBSEQUENT EVENTS:

Dividends:

On April 20, 2023, the Board of Directors authorized a dividend of $1.00 per share payable on May 23, 2023 to shareholders of record at the close of business on May 9, 2023.

Change in Mexican Mining Law:

On April 29 2023, Mexican Senate approved a fast-track bill that would impact the mining industry. The main aspects that will be affected by this legislation are as follows:

First, the mining concession period for new projects will be shortened from 50 years to 30 years plus two renewal periods for new concessions, the second of which will require a tender where the holder of the concession will be given preference.

Second, new restrictions and conditions have been set forth for water use. Under this legislation, companies must recover at least 60% of the water utilized. Water rights will be conceded by the National Water Commission “CONAGUA” for a period that matches the concession period and operations must measure their use. It is important to note the SCC currently exceeds all of these requirements through a comprehensive water management plan, which contemplates best environmental and social practices.

Third, companies must establish a financial vehicle that acts as a guarantee to cover potential environmental liabilities and to cover restoration, closure, post-closure and remediation. SCC’s responsible approach to prevention, and the fact that it is subject to stricter guidelines for environmental obligations under USGAAP ASC 410, means that the Company is already well ahead of the curve in this regard.

Fourth, the Law stipulates significant changes to exploration governance. Under this legislation, exploration will be conducted by a state-run entity, the Mexican Geological Service (SGM). Private parties can present information on the potential existence of minerals to the Secretariat of the Economy, which will decide if exploration should proceed. This represents a significant impact for companies that invest in exploration projects, and SCC is not the exception. The Company will be analyzing this situation as it evolves.

Fifth, no concessions will be granted in National Protected Areas (ANP) and the requirement to remit 5% of net earnings to indigenous communities for new projects.

Down the line, the aforementioned changes could trigger amendment, additions and repeals of provisions of a number of laws, including the Mining Law, the National Water Law, the General Law for Ecological Balance and Environmental Protection and the General Law for the Prevention and Management of Mine Waste.

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, 2022.

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 and our principal operations are in Peru and Mexico. We also have 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 through a number of dedicated mining facilities in Mexico.

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

●	Sales structure: In the first quarter of 2023, approximately 76.9% of our revenue came from the sale of copper; 10.8% from molybdenum; 4.1% from silver; 3.3% from zinc; and 4.9% from various other products, including gold, sulfuric acid, and other materials.

●

Copper: In the first quarter of 2023, the LME copper price decreased from an average of $4.53 per pound in the first quarter of 2022 to $4.05 (-10.6%), reflecting concerns about a possible recession in the U.S. and Europe, partially offset by the good news on China´s economy, which is growing at a higher pace than expected.

Current prices for copper are at around $4.00 per pound, reflecting a positive outlook for this market, due to the following factors:

●

A reduction in global inflation, which may slow down or even stop the interest rates hike cycle led by the FED and the ECB.

●

The mentioned bouncing back of the Chinese economy with GDP growth of 4.5%.

●

Uncertainty regarding future production growth in Chile and Peru, which together represent about 40% of the global supply. Chile recently reported a copper production decline of 4% for March of this year.

●

The most relevant market intelligence houses for the copper market are currently expecting a market in balance or a small deficit of about 100,000 tons for 2023. This assumes a growth in demand of about 2.0-2.5% this year, but a lower than expected supply growth estimated at about 1.5-2.0% due to the first quarter stoppages in South America.

●

Low copper inventories, which stood at 411,000 tons as of March 31, 2023. These are one of the lowest since 2005.

It is important to emphasize that copper plays a leading role in the global shift to clean energy, which correlates positively with our assertion that the underlying demand for copper will be strong in the long-term. In this scenario, we believe the current cycle of low prices should be short-lived.

Table of Contents

●	Molybdenum: Accounted for 10.8% of our sales in the first quarter of 2023 and is currently our most important by-product. Molybdenum prices averaged $32.04 per pound in the first quarter of 2023, compared to $18.99 in the same period of 2022, reflecting an increase of 68.7%.

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 associated with lubricants, sulfur filtering of heavy oils and shale gas production.

●	Silver: Represented 4.1% of our sales in the first quarter of 2023. We believe that the prices for silver will be supported by intensive level of industrial use.

●	Zinc: Represented 3.3% of our sales in the first quarter of 2023, with an average price of $1.42 per pound in the quarter, down 16.5% from the first quarter of 2022. Zinc is currently our third by-product.

●

Production: For 2023, we expect production to reach approximately 939,400 tonnes of copper, which represents an increase of 5% compared to our 2022 production. This growth will unfold as we get Peruvian production back on track which coupled with new production in our Mexican operations through our Pilares and Buenavista Zinc Concentrator projects.

We also expect to produce 23,400 tonnes of molybdenum, which represents a decrease of 10.8% over our 2022 production level. In 2023, we expect to produce 20.3 million ounces of silver, an increase of 9.1% compared to 2022 production level. Additionally, we expect to produce 116,300 tonnes of zinc from our mines. which represents an increase of 93.8% over our 2022 production level. This growth will be driven by the production start-up of the Buenavista Zinc operations (+51,600 tonnes) and by the recovery of the IMMSA mines production (+6,200 tonnes), where better ore grade areas have been identified. For 2024 and on we expect to produce over 200,000 tonnes of zinc per year.

●

Capital Investments: In the first quarter of 2023, we spent $238.1 million on capital investments; this represented 29.3% of net income and an increase of 16.0% compared to the amount registered for the same period in 2022. We continue to advance our projects, including the Buenavista Zinc, El Pilar and Pilares projects, which have registered good progress.

CYBERSECURITY

In the first quarter of 2023, we have had no material cybersecurity incidents. This is due to the Information Security Strategy that we have implemented and the commitment of our entire organization to consolidate a living and effective security culture.

Our focus on information security continues to be a strategic priority, our security policy focuses on continuously identifying and managing risks through standard frameworks and best practices. In addition to the training and awareness that we extend to our employees, we constantly monitor the effectiveness of our controls.

The Board of Directors has been proactive in its approach to cybersecurity, seeking to ensure that our organization remains secure and resilient to cyber threats, we have significantly improved our security posture and continue to moving forward with our information security strategy.

We know that, in today's environment, cyber threats are becoming more sophisticated and rapidly evolving risk management is critical to long-term business success. We remain alert to emerging challenges and with active investment processes to evolve our capabilities, improve our processes and promote the development of a safety culture in our organization.

KEY MATTERS

Below, we discuss several matters that we believe are important to understand the results of our 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, 2023 and 2022 (in millions, except copper price, percentages and per share amounts):


		Three months ended March 31,
	2023		2022		Variance		% Change
Copper price LME		4.05		4.53		(0.48)	(10.6)	%
Pounds of copper sold		504.3		458.4		45.9	10.0	%
Net sales	$	2,793.9	$	2,763.8	$	30.1	1.1	%
Operating income	$	1,353.7	$	1,470.1	$	(116.4)	(7.9)	%
Net income attributable to SCC	$	813.2	$	784.7	$	28.5	3.6	%
Earnings per share	$	1.05	$	1.02	$	0.03	2.9	%
Dividends per share	$	1.00	$	1.00	$	—	—	%

Net sales in the first quarter of 2023 were 1.1% higher than in the same period of 2022. This increase was driven by an increase in sales volumes of copper (+10.0%), silver (+15.5%) and zinc (+6.4%) and by an uptick in molybdenum (+68.7%) prices. This effect was offset by lower sales volumes of molybdenum (-7.9%) and by a drop in prices of copper (-10.6% - LME), silver (-6.3%) and zinc (-16.5%).

Net income attributable to SCC in the first quarter of 2023 was 3.6% higher than in the same period of 2022. This increase was mainly attributable to the higher sales volumes of copper, silver and zinc; this effect was slightly offset by a drop in average prices for metals with the exception of molybdenum, as well as by a decrease in the sales volumes of molybdenum.

Production: The table below highlights our mine production data for the three months ended March 31, 2023 and 2022:


	Three months ended March 31,
	2023	2022	Variance	% Change
Copper (in million pounds)	492.2	472.8	19.4	4.1	%
Molybdenum (in million pounds)	14.2	15.6	(1.4)	(8.8)	%
Silver (in million ounces)	4.4	4.3	0.1	3.1	%
Zinc (in million pounds)	33.2	32.5	0.8	2.4	%

The table below highlights our mine production data for the three months ended March 31, 2023 and 2022:


	Three Months Ended March 31,
Copper (in million pounds):	2023	2022	Variance	% Change
Toquepala	113.1	112.5	0.6	0.6	%
Cuajone	80.0	53.8	26.2	48.5	%
La Caridad	57.6	64.5	(6.9)	(10.8)	%
Buenavista	236.9	237.7	(0.8)	(0.3)	%
IMMSA	4.6	4.3	0.3	7.5	%
Total mined copper	492.2	472.8	19.4	4.1	%

First quarter: Mined copper production in the first quarter of 2023 increased 4.1% to 492.2 million pounds compared to 472.8 million pounds in the first quarter of 2022. This was mainly attributable to the fact that production at our Cuajone mine was up 48.5% YoY. This result was driven by higher ore grades and a return to full operating capacity this year. Production at our Toquepala mine and IMMSA operations increased 0.6% and 7.5% respectively with regard to the

Table of Contents

figures reported in the first quarter of 2022, driven by higher ore grades and recoveries. This was slightly offset by a drop in production at our Buenavista (-0.3%) and La Caridad (-10.8%) mines due to lower ore grades and recoveries.

Molybdenum production fell 8.8% in the first quarter of 2023 compared to the levels registered in the first quarter of 2022. This was attributable to a drop in production at our Toquepala mine (-45.6%) which was mainly driven by a reduction in ore grades. This effect was partially offset by an increase in production at our Cuajone (+66.7%), La Caridad (+5.2%) and Buenavista (+0.1%) mines due to higher ore grades and the fact that production level at Cuajone mine normalized after the stoppage ceased.

Silver mine production increased 3.1% in the first quarter of 2023 compared with the same period of 2022. This was mainly attributable to a higher production at our Cuajone (+44.3%) and Toquepala (+9.3%) mines. This was offset by lower production at our La Caridad (-10.0%), Buenavista (-2.1%) and IMMSA (-1.5%) mines.

Zinc production increased 2.4% in the first quarter of 2023 compared to the same period in 2022. This result was mainly attributable to an uptick in mineral production at the San Martin and Santa Barbara units, which was partially offset by a decrease in production at the Charcas mine.

Operating Cash Costs: An overall benchmark that we use, which is 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 consolidated statement of earnings is presented under the subheading, “Non-GAAP Information Reconciliation” on page 51. 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. Additional exclusions 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 allow our management and stakeholders to more fully visualize our controllable cash cost, which we believe is one of the lowest of all 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 covering 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.

Table of Contents

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 areas of concern within operating management. 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 to determine whether to move forward or not in 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, 2023 and 2022:

Operating cash cost per pound of copper produced (1)

(In millions, except cost per pound and percentages)


		Three Months Ended March 31,
	2023		2022		Variance		% Change
Total operating cash cost before by‑product revenues	$	987.7	$	837.7	$	150.0	17.9	%
Total by‑product revenues	$	(630.6)	$	(583.5)	$	(47.1)	8.1	%
Total operating cash cost net of by‑product revenues	$	357.1	$	254.2	$	102.9	40.5	%

(1)	These are non-GAAP measures. Please see page 51 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 2023 was 14.2% higher than in the same period of 2022. This increase was mainly attributable to an increase in production costs and slightly offset by the unit cost effect generated by a 3.3% increase in pounds of copper produced. Our cash cost per pound net of by-product revenue for the first quarter of 2023 increased 38.2% when compared to the same period of 2022. This was mainly driven by an uptick in the production cost, which was partially offset by an increase in by-product revenue credits due to higher sales volume in most of our by-products.

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, and for copper, molybdenum, zinc and silver in particular.

We are subject to market risks arising from the volatility of copper and other metal prices. For the remaining nine months of 2023, assuming that expected metal production and sales are achieved, tax rates remain unchanged and no effects are generated by 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		Molybdenum		Zinc		Silver
Change in metal prices (per pound except silver—per ounce)	$	0.10	$	1.00	$	0.10	$	1.00
Change in net earnings (in millions)	$	93.9	$	22.5	$	18.2	$	9.5

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

Table of Contents

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, 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 14 “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 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 $238.1 million in the three months ended March 31, 2023, compared to $205.2 million in the same period of 2022. 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 by utilizing cash on hand; internally generated funds and additional external financing. All capital spending plans will continue to be reviewed and adjusted to respond to changes in the economy and market conditions.

Projects in Mexico:

Buenavista Zinc - Sonora: This project is located within the Buenavista deposit, where a new concentrator is being built. This facility has a production capacity of 100,000 tonnes of zinc and 20,000 tonnes of copper per year. We have completed the engineering study and the project has all the necessary permits. When operating, this facility will double the Company’s zinc production capacity and will provide more than 2,000 operational jobs.

Project update: the capital budget of the project is $416 million, most of which has already been invested. We expect to initiate operations in the second half of 2023.

Pilares - Sonora: Located six kilometers from La Caridad, this project consists of an open-pit mine operation with an annual production capacity of 35,000 tonnes of copper in concentrate. This project will significantly improve the overall mineral ore grade (considering the 0.78% expected from Pilares with 0.29% from La Caridad).

Project update: The budget for Pilares is $176 million, of which $114 million has been invested. Pilares is currently operating and delivering copper mineral oxides to the SX-EW facilities of the Caridad operation. We expect to produce mineral for the Caridad concentrator at full capacity in the second quarter of 2023.

El Pilar - Sonora: This low-capital intensity copper greenfield project is strategically located in Sonora, Mexico,

approximately 45 kilometers from our Buenavista mine. Its copper oxide mineralization contains estimated proven and

probable reserves of 317 million tonnes of ore with an average copper grade of 0.249%. We anticipate that El Pilar will

operate as a conventional open-pit mine with an annual production capacity of 36,000 tonnes of copper cathodes. This

operation will use highly cost efficient and environmentally friendly SX-EW technology. The budget for El Pilar is $310

million.

Project update: The results from experimental pads in the leaching process have confirmed adequate levels of copper recovery. The basic engineering study is finished and the Company continues developing the project and engage in onsite environmental activities. Detailed engineering is on-going at the SX-EW plant. We expect production to begin in 2025 and mine life is estimated at 13 years.

Table of Contents

Lime plant - Sonora: As part of our cost improvement projects, we built a new lime plant with a production capacity of 600 metric tonnes per day, which will be the largest lime plant of Mexico. This facility will allow us to reduce to approximately 50% our current lime cost at our Mexican operations. The total budget for the plant is $65.5 million, of which we have invested $63.8 million as of March 31, 2023. The furnace of the plant started operations in the second quarter of 2022, complying with the performance tests.

Projects in Peru:

Quebrada Honda dam expansion – Tacna: This project aims to enlarge the main and lateral dams in Quebrada Honda and

includes the relocation and repowered of some facilities due to dam growth and implementation of other facilities for water recovery, among other factors. As of March 31, 2023, the drainage works and removal of Eolic material for the main and lateral dam had been completed; complementary operational works are underway and expected to finish in the second quarter 2023. This project has a total budget of $165.0 million, of which we have invested $148.3 million as of March 31, 2023.

Tia Maria - Arequipa: This greenfield project, located in Arequipa, Peru, will use state of the art SX-EW technology with the highest international environmental standards to produce 120,000 tonnes of SX- EW copper cathodes per year. The estimated capital budget for the project is $1.4 billion.

The Company has been consistently working to promote the welfare of the Islay province population. As part of these efforts, we have implemented successful social programs in education, healthcare and productive development to improve the quality-of-life in the region. We have also promoted agricultural and livestock activities in the Tambo Valley and supported growth in manufacturing, fishing and tourism in Islay.

We reiterate our view that the initiation of construction activities at Tia Maria will generate significant economic opportunities for the Islay province and the Arequipa region. Given the current Peruvian economic situation, it is crucial to move ahead on projects that will stimulate a sustainable growth cycle. We will make it a priority to hire local labor to fill the 9,000 jobs that we expect to generate during Tia Maria’s construction phase. Additionally, from day one of our operations, we will generate significant contributions to revenues in the Arequipa region.

Potential projects

We have a number of other projects that we may develop in the future. We continuously 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 and 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 1,230 million tonnes with an average ore grade of 0.40% and 141 million tonnes of leach material with an average ore grade of 0.27%. The project includes an open-pit mine with a combined concentrator and SX-EW operations. Annual production is expected to total 190,000 tonnes of copper and 105,000 ounces of gold.

Project update: The Company has completed the environmental baseline study for the mine and industrial facilities and is reviewing the basic engineering analysis to request the environmental impact permits.

Los Chancas - Apurimac: This greenfield project, located in Apurimac, Peru, is a copper and molybdenum porphyry deposit. Current estimates of indicated copper mineral resources are 98 million tonnes of oxides with a copper content of 0.45% and 52 million tonnes of sulfides with a copper content of 0.59%. The Los Chancas project envisions an open-pit mine with a combined operation of concentrator and SX-EW processes to produce 130,000 tonnes of copper and 7,500 tonnes of molybdenum annually. The estimated capital investment is $2,600 million and the project is expected to be in operation in 2030. In 2022, we continued to engage in social and environmental improvements for the local communities and worked on the project´s environmental impact assessment.

Project update: As of March 31, 2023, part of the project´s land continued to be occupied by illegal miners, 70 of whom have irregularly registered their stakes in the "Integral Registry of Mining Formalization" (REINFO). The Company has requested that these 70 informal miners be excluded from REINFO. In response, the competent authority has eliminated these individuals from the registry of formal mining interests. The Company has also filed criminal complaints and other legal remedies to physically expel the illegal miners from the Project.

Michiquillay Project - Cajamarca: In June 2018, Southern Copper signed a contract for the acquisition of the Michiquillay project in Cajamarca, Peru. Michiquillay is a world class mining project with inferred mineral resources of 2,288 million tonnes with an estimated copper grade of 0.43%. When developed, we expect Michiquillay to produce 225,000 tonnes of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years and at a competitive cash-cost. We estimate an investment of approximately $2.5 billion will be required and expect production start-up by 2032. Michiquillay will become one of Peru´s largest copper mines and will create significant business opportunities in the Cajamarca region; generate new jobs for the local communities; and contribute with taxes and royalties to the local, regional and national governments.

In 2021, the Company signed Social Agreements with the Michiquillay and the Encañada Communities. In addition, on

October 1, 2021, the Peruvian Ministry of Energy and Mines approved the semi-detailed Environmental Impact Study for the project.

Project update: In the fourth quarter of 2022, the Company informed MINEM that it had begun exploration activities and initiated an assessment of the existing mineral resource at depth. In 2023, in accordance with our social agreements with the Michiquillay and La Encañada communities, the Company has hired unskilled labor and is paying for the use of surface land. We are supporting social programs in both communities as we roll out exploration activities.

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.

ENVIRONMENTAL, SOCIAL AND CORPORATE GOVERNANCE (“ESG”)

Sustainable Development Report. This year, Grupo Mexico will present edition N◦ 15 of the Sustainable Development Report, which contains disaggregated information from Southern Copper Corporation and reaffirms our commitment to transparency and on-going improvement. In 2022, we have placed particular importance on updating our strategy for climate change, which includes targets to reduce greenhouse gas emissions. This year’s report also provides information on our program and objectives with regard to promoting diversity and inclusion both inside the Company and within the communities close to our operations.

Sustainable Development Committee. In 2022, SCC set up a Sustainable Development Committee, which is presided by an independent Director. This committee’s main objective is to support SCC’s Board of Directors in its endeavors to supervise management of risks and opportunities in the environmental, safety and health, community development, human rights and corporate governance ambits. The committee meets every quarter and has assessed diverse aspects of the Company’s ESG trajectory, including adhesion to international agreements and management of water and mineral waste. The Sustainable Development Committee, in its third session, addressed climate change as well as diversity and inclusion and identified opportunities on the corporate governance front.

Third-party certification. In line with our commitment to implement best environmental, social and corporate governance practices, our Buenavista del Cobre mine, located in Sonora (Mexico), has obtained certification for three important ISO (International Organization for Standardization) standards: ISO 9001 for quality management; ISO 14001 for environmental management; and ISO 45001 for occupational safety and health management. These certifications are indicative of our commitment to the environment, to quality and to the health and occupational safety of our employees.

Occupational Safety and Health. At SCC, our employees’ safety is our priority. Our unit in Ilo, located in Moquegua, Peru, has earned first place in the Smelter and Refinery category of the XXVI National Competition for Mining Safety (Concurso Nacional de Seguridad Minera) organized by the Instituto de Seguridad Minera. This award recognizes SCC’s

Table of Contents

performance with regard to indicators of our employees’ occupational safety and health and is a reflection of our on-going commitment to ensure the sustainability of our operations.

Biodiversity. In March 2023, the Environmental Management Unit at Buenavista del Cobre obtained certification from the Wildlife Habitat Council in recognition of our contributions to efforts to prevent the extinction of the Mexican grey wolf, which was on the brink of extinction in the wild. On account of our contributions, the species have been able to multiply in their natural habitat in Mexico. Going forward, we will continue to work side-by-side with society and authorities to serve the common good in the regions in which we operate.

Community Development. At SCC, we continue to strengthen our community development model and currently operate 29 community centers that provide services to 350 thousand people a year in Mexico and Peru. These efforts positively impact the quality of life of the residents in the communities where we work. Recently, we renovated two community centers (called Casa Grande) in Santa Barbara, Chihuahua and Charcas, San Luis Potosi. These facilities will serve an additional 21 thousand residents by providing spaces to learn and develop bonds. Both centers are equipped with a library, a game area, an audiovisual room, computer centers, physical activation spaces, areas for temporary exhibits, and grass areas.

Diversity and Inclusion. At SCC, we are convinced that valuing diversity, preventing discrimination, and promoting

openness to different ways of thinking are fundamental in all efforts to develop inclusive workplace environments that

promote the integral development of our employees and stakeholders. We are committed to driving the agenda for

diversity and inclusion transversally throughout the Company and in the communities around our operations. Our

results in 2022 reflect the fruit of our efforts, with a 16% increase in the number of women employed by SCC.

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 reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

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, 2023.

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. Given that 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 assets denominated in soles or pesos can be affected by an exchange rate variance 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, 2023 and 2022:


	Three Months Ended
	March 31,
	2023		2022
Peru:
Peruvian inflation rate	1.8	%	1.8	%
Initial exchange rate	3.820		3.998
Closing exchange rate	3.765		3.701
Appreciation/(devaluation)	1.4	%	7.4	%
Mexico:
Mexican inflation rate	1.5	%	2.4	%
Initial exchange rate	19.362		20.584
Closing exchange rate	18.105		19.994
Appreciation/(devaluation)	6.5	%	2.9	%

Change in monetary position:

Assuming an exchange rate variance of 10% at March 31, 2023, we estimate our net monetary position in Peruvian sol and Mexican peso would increase (decrease) our net earnings as follows:


	Effect in net
	earnings
	($ in millions)
Appreciation of 10% in U.S. dollar vs. Peruvian sol	$	14.6
Devaluation of 10% in U.S. dollar vs. Peruvian sol	$	(17.8)
Appreciation of 10% in U.S. dollar vs. Mexican peso	$	(11.7)
Devaluation of 10% in U.S. dollar vs. Mexican peso	$	14.3

Table of Contents

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 13 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, 2023.

Derivative Instruments:

From time to time, we use derivative instruments to manage our cash flows exposure to changes in commodity prices. We do not enter into derivative contracts unless we anticipate that the possibility exists that future activity will expose our future cash flows to deterioration. Derivative contracts for commodities are entered into to manage the price risk associated with forecasted purchases of the commodities that we use in our manufacturing process.

Cash Flow Hedges of Natural Gas

Our objective in using natural gas derivatives is to protect the stability of natural gas costs and manage exposure to natural gas price increases. To protect natural gas costs from estimated price increases in 2021, we acquired two derivative instruments that began in November 2021 and ended in March 2022.

We assessed these derivative instruments as Cash Flow Hedges. As such, the effective portions of said hedges were initially reported in Other Comprehensive Income (OCI) and were reclassified as earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affected earnings. The Company did not identify any ineffective portions of these derivatives.

As of March 31, 2023, we held no derivative instruments.

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, 2023, 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, 2023, to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is:

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

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

There were no 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 three months ended March 31, 2023 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, 2023, the related condensed consolidated statements of earnings, comprehensive income and cash flows for the three-month periods ended March 31, 2023, and 2022, 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, 2022, 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 February 28, 2023, 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, 2022 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 consolidated financial statements taken as a whole. Accordingly, we do not express such an opinion.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings:

The information provided in Note 10 “Commitments and Contingencies” to the condensed consolidated financial statements contained in Part I of this Form 10-Q, is incorporated herein by reference.

Item 1A. Risk Factors:

The Company's operations and financial results are subject to various risks and uncertainties, including those described in “Risk Factors” included in Part I, Item 1A of our Annual report on Form 10-K for the year ended December 31, 2022 filed with the SEC on February 28, 2023. The following supplements and updates the risk factor previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022.

Mexican economic and political conditions, as well as drug related violence, may have an adverse impact on our business

On April 29 2023, Mexican Senate approved a fast-track bill that would impact the mining industry. The main aspects that will be affected by the legislation are changes in mining concession period from 50 to 30 years; new restrictions and conditions for water use; provide of guarantees for closure and remediation of operations, 5% contribution of net earnings to indigenous communities for new projects and finally significant changes to exploration activities.

Although the Company believes that there would be no material impact on the Company's operations or financial condition, we cannot assure you that future developments in these laws will not affect our current business as well as our organic growth portfolio.

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 as of March 31, 2023 was $76.25 and the maximum number of shares that the Company could purchase at that price was 1.1 million. 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, 2023. There has not been any activity in the SCC share repurchase program since the third quarter of 2016.

Item 4. Mine Safety Disclosures:
