Current report

Our operations are subject to risks associated with the management of waste rock and tailings storage facilities, which are subject to significant environmental, safety and engineering challenges that could adversely affect our business.

Current report

The waste rock and tailings produced in our mining operations represent our largest volume of waste material. Managing a high volume of waste rock and tailings presents significant environmental, safety and engineering challenges and risks primarily relating to structural stability, geochemistry, water quality and dust generation. We maintain large tailings impoundments containing ground rock sand that is moistened with water; these areas are effectively large dams that must be engineered, built and monitored to assure structural stability and avoid leakages or structural collapse. Our tailings impoundments must have effective programs to suppress dust emissions to meet regulatory requirements, which vary depending on the jurisdiction, and to limit potential impacts of our operations’ dust emissions on the environment and the adjacent communities. Management of this waste is regulated in the jurisdictions where we operate and our waste management programs are designed to comply with our permits, approved environmental impact studies and applicable laws.

Current report

Defects and/or failures of tailings storage facilities, other impoundments or stockpiles at any of our mining operations could cause severe, and in some cases catastrophic, property and environmental damage and loss of life, as well as adversely affect our business and reputation.

Current report

The importance of careful design, management and monitoring of large tailings impoundments has grown in recent years due to large-scale tailings dam failures at the mining operations of companies, unaffiliated with the Company, which caused extensive property and environmental damage and, in certain instances, resulted in the loss of life. The failure or loss of integrity of a tailings storage facility or related waste management infrastructure—whether due to operational deficiencies, extreme weather events, seismic activity, regulatory constraints or other factors beyond our control—could result in the release of tailings, process water or other materials, causing environmental harm and potential impacts to surrounding communities, damage to, or destruction of mining operations, resulting in monetary losses and possible legal liability. Such events could materially adversely affect our results of operations and financial condition, disrupt operations, damage our reputation, and subject the Company to regulatory enforcement actions, fines, remediation obligations and claims from governmental authorities or third parties. For more information regarding our tailings dams, please see Item 2 “Properties—Slope Stability—Tailings Dams.”

Current report

Our business operations may be adversely affected by changes in regulatory policy or the imposition of new tariffs or other trade restrictions, which could significantly increase our costs, pricing strategies, disrupt our supply chain and complicate international sourcing and customer relationships. Uncertainty about future trade or tariff measures may hinder planning, force pricing adjustments, and reduce our competitiveness. If such developments occur, they could have a material adverse effect on our margins, results of operations and market position.

Current report

Changes in international trade policies and relationships may materially adversely affect global commodity prices and market conditions and our business, financial condition and results of operations. The adoption and expansion of trade restrictions; tariffs, taxes or other governmental trade measures and uncertainty about such trade measures could reduce the demand for our products, increase our costs, disrupt customer and supplier relationships and harm the U.S. economy, any of which could materially impair our cash flows, competitive position, financial condition and results of operations. In July 2025, the U.S. announced trade agreements with the European Union and Japan. On July 30, 2025, the U.S. announced a 50% tariff on semi-finished copper products and copper-intensive derivative products, which became effective on August 1, 2025. Additionally, reciprocal tariffs with China have been suspended until November 10, 2026. On February 20, 2026, the U.S. Supreme Court issued an opinion that limited the President’s authority to impose certain tariffs under emergency powers, which may affect the scope, duration and future use of tariff measures by the U.S. presidential administration. In response, the U.S. presidential administration declared they would impose a 15% global tariff. These developments have produced and may continue to produce market volatility for our principal products and our common stock. We cannot assure investors that future tariff actions, trade tensions, or related regulatory changes will not adversely affect our product prices, stock price, financial condition or results of operations.

Current report

Peruvian congress immediately assumed the presidency, in the absence of a Vice President. However, on February 17, 2026, the interim president was impeached four months into his term. On February 18, 2026, a new interim president was appointed. This new president leads a transitional government in Peru, which is due to hold general elections in April 2026 amidst political turmoil.

Applicable law restricts the payment of dividends from our Minera Mexico subsidiary to us.

Previous report

Our subsidiary, Minera Mexico, is a Mexican company and, as such, may pay dividends only out of net income that has been approved by shareholders. Shareholders must also approve the actual dividend payment, after mandatory legal reserves have been created and losses for prior fiscal years have been satisfied. These legal constraints may limit the

ability of Minera Mexico to pay dividends to us, which in turn, may have an impact on our ability to pay stockholder dividends or to service debt.

Previous report

Our business operations may be adversely affected by changes in regulatory policies. Imposing new tariffs on imports could significantly affect our cost structures and pricing strategies. The uncertainty surrounding potential tariff policies may complicate our supply chain planning and international trade relationships while increasing costs for raw materials and goods. These events, should they materialize, may impact our profitability and competitive positioning in the market.

Previous report

Additionally, changes in international trade policies and relationships may affect global commodity prices and market conditions and could have a material adverse impact on our business and results of operations. The adoption and expansion of trade restrictions; trade tensions; or other changes in governmental policies related to taxes, tariffs, trade agreements or any policies, are difficult to predict and could adversely affect the demand for our products, our costs, our customers, our suppliers and the U.S. economy and, consequently, could have a material adverse effect on our cash flows, competitive position, financial condition or results of operations.

regarding future inflation rates; currency exchange rates and changes in technology. In addition, the market prices of copper and certain other metals have on occasion been subject to rapid short-term changes. At the start of the pandemic in 2020, copper prices were initially impacted by economic uncertainty. However, in mid-2020, copper prices began to rise and reached a record highs during 2021. Volatility in global economic growth, particularly in developing countries, has the potential to adversely affect future demand and prices for commodities. Geopolitical uncertainty and protectionism have the potential to inhibit international trade and negatively impact business confidence, which can create price volatility and constraints on our ability to trade in certain markets.

Current wording

Our financial performance is significantly affected by the market prices of the metals that we produce, particularly the market prices of copper, molybdenum, zinc and silver. Historically, these prices have been subject to wide fluctuations and are affected by numerous and complex factors beyond our control. Market prices are affected by a number of factors, including global economic and political conditions in general, and in particular by: international policies and regulations in the ambits of trade, taxes and tariffs; levels of supply and demand; the availability and cost of substitutes; inventory levels maintained by users; actions of participants in the commodities markets; interest rates; expectations regarding future inflation rates; currency exchange rates and changes in technology. In addition, the market prices of copper and certain other metals have on occasion been subject to rapid short-term changes. At the start of the pandemic in 2020, copper prices were initially negatively impacted by economic uncertainty. Copper prices began to recover in mid-2020 and continued to strengthen, reaching record levels in 2025. Volatility in global economic growth, particularly in developing countries, has the potential to adversely affect future demand and prices for commodities. Geopolitical uncertainty and protectionism have the potential to inhibit international trade and negatively impact business confidence, which can create price volatility and constraints on our ability to trade in certain markets.

Previous wording

Through 2024, the Company recognized the expected future tax benefit from deferred tax assets when the tax benefit was considered more likely than not to be realized. A valuation allowance is provided for those deferred tax assets for which management believes that the related benefits will not be realized. Determining the amount of the valuation allowance and assessing the recoverability of deferred tax assets requires management to make significant estimates related to expectations of future taxable income and existing tax laws. There can be no assurance that the Company will be able to recognize the expected future benefits of deferred tax assets; this inability could have a material adverse effect on the Company’s financial results.

Previous wording

However, the success of the energy transition is intrinsically linked to copper, our key product, critical for the production of technological solutions to the decrease the global greenhouse gas (GHG) emissions. Given copper's crucial role in electrification and the generation of clean energies, there exists an increasing expectation from both corporate entities and societal stakeholders that copper sourcing should emanate from entities committed to rigorous and responsible production practices.

Previous wording

We require substantial amounts of fuel oil, electricity, water and other resources for our operations. Fuel, gas and power costs constituted approximately 26% of our total production cost in 2024, 29% in 2023 and 34% in 2022. We rely upon third parties for our supply of the energy resources consumed in our operations. Therefore prices for and availability of energy resources may be subject to change or curtailment due to new laws or regulations; imposition of new taxes or tariffs; interruptions in production by suppliers; and variations in global prices or market conditions, among other factors. Regarding water consumption, although each of our operations currently has sufficient water supplies to cover its operational demands, the loss of some or all water rights for any of our mines or operations, in whole or in part, shortages relative to the water to which we have rights or a lack of additional back-up water supplies at an acceptable cost, or at all, could require us to curtail or shut down mining production and could prevent us from pursuing expansion opportunities, thereby increasing and/or accelerating costs or foregoing profitable operations. In addition, future shortages of critical parts, equipment and skilled labor could adversely affect our operations and development projects.

In 2024, we recorded one fatality of a contractor. In 2023, we recorded five fatalities (two contractors and three employees) and in 2022, four fatalities (two contractors and two employees) were registered. The amounts paid to the Mexican and Peruvian authorities for reportable accidents had no adverse effects on our results. Under Mexican and Peruvian law penalties and fines for safety violations are generally monetary, but in certain cases may lead to the temporary or permanent shutdown of the affected facility or the suspension or revocation of permits or licenses. Additionally, violations of security and safety laws and regulations at our Peruvian operations can be considered criminal activity and punishable by a sentence of up to 10 years of prison.

Previous wording

Metals exploration is highly speculative in nature because it involves many risks and is frequently unsuccessful. Once mineralization is discovered, it may take a number of years from the initial phases of drilling until production is possible. During such time the economic feasibility of production may change. Substantial expenditures must be made to determine proven and probable mineral reserves, which requires drilling to establish the metallurgical processes that will be needed to extract the metals from the ore and, in the case of new properties, to construct mining and processing facilities. We cannot assure you that our exploration programs will result in the expansion or replacement of current production with new proven and probable mineral reserves.

Previous wording

On December 7, 2022, the Peruvian congress invoked its powers under the Constitution to remove the current President from office. The Vice President immediately assumed the presidency, which has led to considerable turmoil, particularly in the south of Peru, where acts of vandalism and violence escalated. Roadblocks were scattered throughout the country, which negatively affected the normal course of business in various regions. Fortunately, our operations were not impacted. This climate of violence gradually subsided during the year and was replaced by a general concern about the economic recession and personal insecurity.
