Buenaventura Announces

Second Quarter and Six-month 2024 Results


Lima, Peru, July 25, 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 second quarter (2Q24) and six-month period ended June 30, 2024 (6M24). 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$).

Second Quarter and Six-Month 2024Highlights:


· 2Q24 EBITDA from direct<br>operations was US$ 106.9 million, compared to US$ 22.1 million reported in 2Q23. 6M24 EBITDA from direct operations reached US$ 201.3<br>million, compared to US$ 68.7 million reported in 6M23.
· 2Q24 net income reached<br>US$ 74.4 million, compared to a US$ 5.4 million net loss for the same period in 2023. 6M24 net income was US$ 141.4 million, compared<br>to US$ 67.5 million in net income for the 6M23.
· Buenaventura's cash position<br>reached US$ 171.5 million by quarter’s end, June 30, 2024, while net debt amounted to US$ 520.5 million, resulting in a Leverage<br>Ratio of 1.40x.
· El Brocal's processing<br>plant facility was voluntarily temporarily suspended for 16 days, as was announced by the Company on May 22, 2024, and resumed operations<br>at midnight on June 7, 2024. El Brocal had accumulated approximately 220,000 tonnes of copper ore upon the plant’s reinitiation,<br>and the processing of this stockpiled inventory, combined with ongoing mine production, is expected to enable El Brocal to meet its nine-month<br>2024 copper production target by September 2024.
· Buenaventura's 2Q24 consolidated<br>silver production increased by 2.4M Oz, zinc production increased by 28% YoY, and lead increased by 86% YoY, primarily due to production<br>initiation at Uchucchacua and Yumpag. Copper production decreased by 22% YoY due to the temporary suspension of El Brocal’s processing<br>plant facility, as well as a 9% YoY decrease in gold due to lower production from the southern mines.
· 2Q24 CAPEX related to San<br>Gabriel was US$ 69.7 million, primarily directed towards the completion of waste dumps and the main substation platform.
· Cerro Verde paid a total<br>dividend of US$ 150 million on April 26, 2024, of which Buenaventura received US$ 29.4 million relative to its stake in Cerro Verde. On<br>July 24, 2024, Cerro Verde announced a second total dividend of US$ 300 million to be paid on August 29, 2024, of which Buenaventura will<br>receive an additional US$ 58.7 million.

CAPEX

2Q24 capital expenditures were US$ 84.2 million, compared to US$ 49.7 million for the same period in 2023. The 2Q24 capex includes US$ 69.7 million for the San Gabriel Project, US$ 5.1 million for the Trapiche Project, US$ 3.6 million for Yumpag, and US$ 6.0 million in sustaining capex. 6M24 capital expenditures reached US$ 142.2 million, compared to US$ 85.9 million in 6M23.

Operating Revenues

2Q24 net sales were US$ 277.1 million, compared to US$ 173.3 million in 2Q23. Increased net sales were due to increased volume of silver, lead and zinc sold, resulting from the reinitiation of the Uchucchacua and Yumpag mines, as well as higher prices during the quarter.

The Company recorded a positive US$ 4.0 million provisional price adjustment for 2Q24. This is comprised of a US$ 3.5 million decrease in fair value of accounts receivables and a US$ 7.5 million increase in adjustments to prior period liquidations in 2Q24. This compares to a negative US$ 17.7 million adjustment for the 2Q23.

Lead and zinc production exceeded 2Q24 projections due to a positive ore grade reconciliation.

Yumpag’s silver production exceeded 2Q24 projections as ore processing was initiated earlier than expected, in March 2024, due to operating permit approval which was initially expected in May 2024.

2Q24 Silver CAS reached 12.56 US$/Oz below initial estimates, also due to the early approval of Yumpag´s operating permit.

El Brocal's 2Q24 copper production decreased by 23% year on year. 2Q24 copper production was below expectations due to a decrease in volume processed during the quarter resulting from a 16 day voluntary temporary suspension of El Brocal’s processing plant facilities, as was announced by the Company on May 22, 2024. 2Q24 silver production decreased by 51% year on year compared to the same period of 2023 when the open pit was in operation.

Buenaventura announced that ore treatment operations at its El Brocal processing plant resumed operations at midnight on June 7, 2024. El Brocal had accumulated approximately 220,000 tonnes of copper ore upon the plant’s reinitiation. The processing of said stockpiled inventories, combined with production from the mine, will gradually ramp to a processing rate of 15,000 tons per day, leveraging the two plants’ previously idle capacity. El Brocal is expected to achieve its nine month 2024 copper production target by September 2024.

The Company’s target to achieve a 11,000 TPD underground mining rate by year end 2024 remains unchanged with an average of 10,800 TPD in the 2Q24.

2Q24 copper CAS increased by 14% year-over-year, primarily due to a decrease in volume processed during the quarter, resulting from the voluntary temporary suspension of the processing plant facilities as described.

Share in Associated Companies

Buenaventura’s share in associated companies was US$ 60.4 million in 2Q24, compared with US$ 7.6 million in 2Q23, comprised of:

Cerro Verde (19.58% owned by Buenaventura)

2Q24 copper production was 109,866 MT, 21,512 MT of which is attributable to Buenaventura; a 6% decrease as compared to 116,431 MT produced in 2Q23, 22,797 MT of which was attributable to Buenaventura.

Cerro Verde reported US$ 316.3 million in 2Q24 net income, compared to US$ 59.5 million in 2Q23 net income. This year on year increase is primarily due to the adverse effects of an unfavorable tax dispute outcome and a provisional price adjustment on Cerro Verde’s 2Q23 net income. Additionally, 2Q24 results reflect a 28% year-on-year net sales increase from a higher average realized copper price of US$4.74 per pound, compared to US$3.52 per pound in 2Q23, partially offset by a 6% decrease in copper volume sold. Further, molybdenum net sales for the quarter increased due to higher prices.

Cerro Verde 2Q24 capital expenditures were US$ 80.4 million.


Coimolache (40.09% owned by Buenaventura)

Coimolache reported a US$ 3.4 million net loss in 2Q24, compared to a US$ 8.1 million net loss in 2Q23.


San Gabriel Project

2Q24 capital expenditures were US$ 69.7 million, primarily directed to the completion of waste dumps (organic, inert and sterile - Phase 0), and San Gabriel’s main substation platform.

The processing plant remains under construction, with significant progress on its foundation- 80% of which has been completed to date- steel, and mechanical works. Electrical and instrumentation works, as well as pipeline activities, are scheduled to begin in 3Q24. Mine development tunneling and infill drilling for the first six months of operation have begun.

*Cerro Verde’s EBITDA accounts for D&A related to the capitalization of the stripping.

Note:

EBITDA (Buenaventura Direct Operations) consists of earnings before net interest, taxes, depreciation and amortization, share in associated companies, net, loss on currency exchange difference, other, net, provision for workers’ profit sharing and provision for long-term officers’ compensation.

EBITDA (including associated companies) consists of EBITDA (Buenaventura Direct Operations), plus (1) Buenaventura’s equity share of EBITDA (Cerro Verde), plus (2) Buenaventura’s equity share of EBITDA (Coimolache). All EBITDA mentioned were similarly calculated using financial information provided to Buenaventura by the associated companies.

Buenaventura presents EBITDA (Buenaventura Direct Operations) and EBITDA (including affiliates) to provide further information with respect to its operating performance and the operating performance of its equity investees, the affiliates. EBITDA (Buenaventura Direct Operations) and EBITDA (including affiliates) are not a measure of financial performance under IFRS and may not be comparable to similarly titled measures of other companies. You should not consider EBITDA (Buenaventura Direct Operations) and EBITDA (including affiliates) as alternatives to operating income or net income determined in accordance with IFRS, as an indicator of Buenaventura’s, affiliates operating performance, or as an alternative to cash flows from operating activities.

APPENDIX 4: 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.
