Compania de Minas Buenaventura SAA (MBU) Risk Analysis

Our shareholders have fewer and less well-defined rights under applicable Peruvian law than they might have as shareholders of a corporation incorporated in a jurisdiction of the U.S. or certain other countries. For example, Peruvian law does not provide for proceedings by which non-controlling shareholders may file class action lawsuits or shareholder derivative actions against controlling shareholders or officers and directors, and the procedural requirements to file shareholder actions in Peru differ from those of the U.S. As a result, holders of our shares may face difficulty enforcing their rights.

We are organized under the laws of Peru. A significant majority of our directors and officers reside outside the U.S. (principally in Peru). All or a substantial portion of our assets or the assets of such persons are located outside the U.S. As a result, it may not be possible for investors to effect service of process within the U.S. upon us or upon such persons or to enforce against them in federal or state courts in the U.S. judgments predicated upon the civil liability provisions of the federal securities laws of the U.S. We have been advised by our Peruvian counsel that there is uncertainty as to the enforceability, in original actions in Peruvian courts, of liabilities predicated solely under the U.S. federal securities laws and as to the enforceability in Peruvian courts of judgments of U.S. courts obtained in actions predicated upon the civil liability provisions of the U.S. federal securities laws.

As of March 31, 2024, Antofagasta plc and two of our directors (and their families), Roque Benavides and Raul Benavides (collectively, the "Benavides Family") held an aggregate of approximately 35% of Buenaventura's outstanding share capital (including outstanding Common Shares and investment shares with a nominal (par) value of ten Peruvian Soles per share, which do not entitle their holders to voting rights ("Investment Shares")). In addition, certain other members of the Benavides Family are believed to hold a significant number of our Common Shares in aggregate. While the Benavides Family is not, to our knowledge, acting together as a group to vote their Common Shares, there can be no assurance that the Benavides Family will not, in the future, form a group for the purpose of voting their Common Shares or exerting influence over the management and policies of Buenaventura. Because of the significant aggregate ownership interest held by individual members of the Benavides Family, the Benavides Family could have the power to elect a significant number of the outstanding directors and exercise significant influence over the outcome of substantially all matters to be decided by a vote of shareholders. In addition, under the terms of the amended and restated deposit agreement dated May 3, 2002 (as further amended and restated as of November 12, 2003, the "Amended and Restated Deposit Agreement"), among us, The Bank of New York Mellon (formerly The Bank of New York), as depositary, or the "Depositary", and the owners and beneficial owners of ADSs, or the Amended and Restated Deposit Agreement, relating to our ADSs, if holders of ADSs do not provide the Depositary with timely instructions for the voting of Common Shares represented by such ADRs, the Depositary will be deemed to be instructed to give a person designated by us, which could be a member of the Benavides Family, a discretionary proxy to vote such shares, unless we inform the Depositary that we do not wish such proxy to be given.
