Buenaventura Announces

Fourth Quarter and Full year 2023 Results

Lima, Peru, February 29, 2024 – Compañia de Minas Buenaventura S.A.A. (“Buenaventura” or “the Company”) (NYSE: BVN; Lima Stock Exchange: BUE.LM), Peru’s largest publicly-traded precious metals mining company, today announced results for the fourth quarter (4Q23) and full year (FY23) ended December 31, 2023. All figures have been prepared in accordance with IFRS (International Financial Reporting Standards) on a non-GAAP basis and are stated in U.S. dollars (US$).

Fourth Quarter and Full Year 2023 Highlights:

· 4Q23 EBITDA from direct operations was US$ 116.4<br>million, compared to US$ 76.9 million reported in 4Q22. FY23 EBITDA from direct operations reached US$ 238.3 million, compared to US$<br>173.1 million reported in FY22.
· 4Q23 net loss from continuing operations reached<br>US$ 3.0 million, compared to a US$ 56.7 million net income for the same period in 2022. FY23 net income from continuing operations was<br>US$ 39.5 million, compared to US$ 124.4 million net income for the FY22.
· Buenaventura's cash position reached US$ 219.8<br>million and net debt decreased to US$ 486.8 million with an average maturity of 2.5 years by quarter’s end, December 31, 2023.
· As planned within its non-core asset divestment<br>strategy, BVN executed the sale of Contacto to Howden for US$33.7 million.
· Production from Yumpag´s pilot stope began<br>in November 2023 producing 2.3 million ounces of silver by quarter’s end. Yumpag continued processing pilot stope ore through<br>January 2024, after which mineral processing was suspended until definitive operating permits have been obtained, expected by the<br>end of 1Q24. Yumpag is therefore expected to initiate mineral processing in 2Q24.
· A US$ 113.2 million provision was made in 4Q23<br>due to an adverse ruling by the Peruvian Supreme Court regarding tax loss carryforwards from 2009 and 2010. This provision negatively<br>affected Buenaventura’s 4Q23 net income. However, it does not imply a cash outflow as it has already been paid.
· On December 14, 2023, Buenaventura received<br>US$49.0 million in dividends related to its stake in Cerro Verde. The Company received a total of US$146.9 million in dividends for FY23.
· Buenaventura’s Board of Directors has proposed<br>a dividend payment of US$ 0.0726 per share/ADS, aligned with the Company’s commitment to shareholder value.

CAPEX

4Q23 capital expenditures were US$ 93.0 million, compared to US$ 58.8 million for the same period in 2022. FY23 capital expenditures reached US$ 238.7 million, compared to US$ 152.0 million in FY22, and includes US$ 94.2 million related to the San Gabriel Project and US$ 49.5 million related to the Yumpag Project.

2024 Guidance: The Company expects total CAPEX between US$ 300 - 320 million for the full year 2024. This includes US$ 65 - 75 million in sustaining CAPEX, which includes investments related to become self-operator at El Brocal, as well as an approximate US$ 15 million investment in Yumpag. Growth CAPEX is estimated to reach between US$ 235 - 245 million related to San Gabriel (~US$ 220 million) and Trapiche.

Operating Revenues

4Q23 net sales were US$ 253.8 million, compared to US$ 246.4 million in 4Q22. Increased net sales were attributed to increased commodity prices and volume of copper and silver sold, driven by the 10,000 tpd underground mine exploitation rate initiative at El Brocal and the restart of Uchucchacua and Yumpag.

The Company recorded a negative US$ 8.9 million provisional price adjustment for the FY23. This is comprised of US$ 8.4 million in fair value of accounts receivables and US$ 0.5 million in adjustments to prior period liquidations. This compares to a positive US$ 5.7 million adjustment for the FY22.

Production and Operating Costs
---

Buenaventura’s 4Q23 equity gold production was 52,231 ounces, compared to 53,079 ounces produced in 4Q22, primarily due to decreased production at La Zanja. 4Q23 silver production was 3,934,706 ounces, compared to 1,678,051 ounces produced in 4Q22, mainly driven by Uchucchacua and Yumpag production initiation. 4Q23 lead and zinc production increased by 52% and 110%, respectively, due to increased production at El Brocal and Uchucchacua, and was partially offset by decreased production at Tambomayo. The Company’s 4Q23 equity copper production was 28,749 MT, compared to 31,479 MT produced in 4Q22, primarily due to decreased production at Cerro Verde.

Tambomayo 4Q23 gold production decreased by 2% year on year, however, this exceeded expectations as grade within areas mined during 4Q23 exceeded prior estimates by 40%. 4Q23 silver production decreased by 24% year on year compared to the same period of 2022, aligned with the Company’s mine plan for this asset. Cost Applicable to Sales (CAS) increased to 1,382 US$/Oz in 4Q23 from 1,129 US$/Oz in 4Q22. This increase was primarily due to decreased by-product credits.

Gold US$/Oz 972 1,676 -42% 1,376 1,393 -1%

Coimolache 4Q23 gold production increased by 30% year-over-year, as optimized leach pad space enabled higher-than-planned volumes of ore treated during 4Q23. This was partially offset by lower grade and longer than expected percolation rates during 4Q23. However, it’s important to note that 65% of full year 2023 production was from the Tantahuatay NW-Ext pit which successfully achieved

4

target production within its first year of operation. CAS therefore decreased to 972 US$/Oz in 4Q23, from 1,676 US$/Oz in 4Q22.

Buenaventura re-initiated Uchucchacua and Yumpag ore processing in the 4Q23 after the Uchucchacua processing plant had been placed under Care and Maintenance (C&M) since 3Q21.

Uchucchacua’s 2023 lead and zinc production surpassed guidance, while silver production underperformed guidance due to a short-term planning adjustment to prioritize processing higher value ore production at Yumpag.

Moving forward, Uchucchacua will primarily treat polymetallic ore, with ore value balanced between silver, lead and zinc- as opposed to exclusively silver ore which was produced previously. Additionally, Buenaventura has optimized Uchucchacua’s operations, which is now operating at approximately ~800 tpd and the plan is to ramp-up to ~1,500 tpd by 4Q24.

Ore processed from the Yumpag pilot stope began simultaneously with that of Uchucchacua in 4Q23. Both mineral outputs from Yumpag and Uchucchacua are treated at the Uchucchacua processing plant. Yumpag 2023 silver production exceeded expectations, offsetting lower production at Uchucchacua. The increased silver production is due to the prioritization of high-grade ore at Yumpag’s pilot stope.

Yumpag continued processing pilot stope ore through January 2024, after which mineral processing was suspended until definitive operating permits have been obtained, expected by the end of 1Q24. Yumpag is therefore expected to begin mineral processing in 2Q24 to achieve its estimated guidance. This suspension does not disrupt Uchucchacua production, which will continue operation per usual.

4Q23 Silver CAS reached 12.09 US$/Oz, which is below the average cost for Uchucchacua-Yumpag’s LOM as, under the exploration permit, costs incurred related to the Yumpag pilot stope mining are considered to be CAPEX. Once the operating permit has been approved, the mining cost which has been recognized as CAPEX will be recognized within Depreciation and Amortization in subsequent operating periods based on IFRS accounting principles.

4Q23 silver production decreased by 45% year on year primarily due to a negative geology reconciliation with decreased treated ore. However, it’s important to note that gold and copper production from the Rosario sector began in December 2023. 4Q23 CAS was 29.05 US$/Oz, compared to 16.05 US$/Oz in 4Q22; an 81% year on year increase due to decreased volume sold.

El Brocal 4Q23 copper production decreased by 7% year on year, primarily attributable to mining within lower grade areas with decreased recovery compared to the previous year, as per the 2023 mine plan.

Record 2023 copper production resulted from successful massive underground method migration completion, enabling El Brocal to ultimately achieve an average of 10,800 tpd during the 4Q23, surpassing its targeted 10,000 tpd underground mine exploitation rate. Record 2023 copper production was also due to the successful implementation of Buenaventura’s plan to increase production at its Marcapunta underground mine to offset the temporary suspension of mining activities at Colquijirca’s Tajo Norte Mine, as was announced on October 3, 2023.

4Q23 silver production increased by 15% year on year, exceeding expectations due to higher-than-expected silver grades at the El Brocal underground mine.

4Q23 zinc production was 10,492 metric tons, compared to 4,037 metric tons in 4Q22. 593,000 tons of polymetallic ore previously considered to be inventories were processed in 4Q23. After a positive metallurgic test result, 245,849 metric tons of ore were added to inventories in December 2023. Approximately 248,000 metric tons of polymetallic ore are expected to be processed in 1Q24, with the remaining polymetallic and copper inventories processed in 2Q23.

4Q23 Copper CAS decreased by 23% year on year, primarily due to higher by-product credits.

Share in Associated Companies

Buenaventura’s share in associated companies was US$ 38.9 million in 4Q23, compared with US$ 58.1 million in 4Q22, comprised of:

Cerro Verde (19.58% owned by Buenaventura)

4Q23 copper production was 104,150 MT, 20,393 MT of which is attributable to Buenaventura; a 10% decrease as compared to 115,131 MT produced in 4Q22, 22,543 MT of which was attributable to Buenaventura.

Cerro Verde reported US$ 165.5 million net income in 4Q23, compared to US$ 312.2 million net income in 4Q22. This decrease is primarily due to a 19% year-on-year decrease in net sales resulting from a 9% decrease in volume of copper sold, as well as a lower average realized copper price of US$3.82 per pound in the 4Q23, compared to US$4.04 per pound in the 4Q22. Further, decreased molybdenum net sales for the quarter was in line with lower realized prices. This decrease was partially offset by a lower tax paid during the quarter.

4Q23 Cerro Verde capital expenditures were US$ 99.3 million.



Coimolache (40.09% owned by Buenaventura)

Coimolache reported US$ 22.4 million in 4Q23 net income, compared to US$ 7.4 million net loss in 4Q22.



San Gabriel Project

4Q23 and FY23 capital expenditures were US$ 47.7 million and US$ 94.2 million, respectively. These expenses were primarily related to earth movement works, underground contractor field work and progress establishing the San Gabriel mining camp. The earthmoving activities were primarily focused on the processing plant platform, which has been 100% completed in the 4Q23. Buenaventura has also invested an additional US$ 33.1 million in the San Gabriel project as advance payment for component equipment manufacturing, primarily related to the processing plant. This amount has been reported within Buenaventura’s financial statements as Fixed Assets – Additions and will be reclassified as CAPEX once Buenaventura has taken delivery of the equipment.

Provision - Tax claim
---

A US$ 113.2M provision was made related to the ongoing tax dispute between Buenaventura and the Peruvian Tax Authority (SUNAT). Said dispute is related to the SUNAT´s refusal to recognize the company´s deductions with respect to contracts for physical deliveries and certain contractual payments made by the Company during the years 2007 and 2008, as well as tax loss which was offset in 2009 and 2010.

This provision has been made based on the recommendation of the Company's Tax Lawyers. However, it is important to note that this provision does not indicate a write-off of the assets held in accounts receivable, as the process remains ongoing. It is important to note that said provision does

7

not imply a cash outflow, as it represents an accounting adjustment and has already been paid in full.

The provision has been recorded under the following Income Statement Accounts: Others, net (US$ -9.6 million), Interest expense (US$ -58.4 million), and Income Tax (US$ -45.1 million).

APPENDIX 5: COST APPLICABLE TO SALES RECONCILIATION


Reconciliation of Costs Applicable to Salesand Cost Applicable to Sales per Unit Sold

Cost applicable to sales consists of cost of sales, excluding depreciation and amortization, plus selling expenses. Cost applicable to sales per unit sold for each mine consists of cost applicable to sales for a particular metal produced at a given mine divided by the volume of such metal produced at such mine in the specified period. We note that cost applicable to sales is not directly comparable to the cash operating cost figures disclosed in previously furnished earnings releases.

Cost applicable to sales and Cost applicable to sales per unit of mineral sold are not measures of financial performance under IFRS and may not be comparable to similarly titled measures of other companies. We consider Cost applicable to sales and Cost applicable to sales per unit of mineral sold to be key measures in managing and evaluating our operating performance. These measures are widely reported in the precious metals industry as a benchmark for performance, but do not have standardized meanings. You should not consider Cost applicable to sales or Cost applicable to sales per unit of mineral sold as alternatives to cost of sales determined in accordance with IFRS, as indicators of our operating performance. Cost applicable to sales and Cost applicable to sales per unit of mineral sold are calculated without adjusting for by-product revenue amounts.

Operations’ Cost applicable to sales does not include operating cost for those months during which Buenaventura’s operations were suspended due to COVID-19, as these have been classified as “Unabsorbed costs due to production stoppage” within the financial statements.

The tables below set forth (i) a reconciliation of consolidated Cost of sales, excluding depreciation and amortization to consolidated Cost applicable to sales, (ii) reconciliations of the components of Cost applicable to sales (by mine and mineral) to the corresponding consolidated line items set forth on our consolidated statements of profit or loss for the three and twelve months ended December 31, 2022 and 2021 and (iii) reconciliations of Cost of sales, excluding depreciation and amortization to Cost applicable to sales for each of our mining units.  The amounts set forth in Cost applicable to sales and Cost applicable to sales per unit sold for each mine and mineral indicated in the tables below can be reconciled to the amounts set forth on our consolidated statements of profit or loss for the three and twelve months ended December 31, 2021 and 2022 by reference to the reconciliations of Cost of sales, excluding depreciation and amortization (by mine and mineral), Selling Expenses (by mine and metal) expenses and Exploration in units in operations (by mine and mineral) to consolidated Cost of sales, excluding depreciation and amortization, consolidated Selling Expenses and consolidated Exploration in units in operations expenses, respectively, set forth below.
