2Q21 net sales were US$ 235.9 million, as compared to US$ 94.2 million reported in 2Q20; a significant year on year increase driven by increased commodity prices during the quarter and an increase in volume sold due to the recovery of operations relative to the impact of COVID-19 on the Company’s operations and related adverse effects on 2Q20 production results.

Royalty income increased 38% to US$ 4.9 million in the 2Q21, from US$ 3.6 million in 2Q20. This was due to a 37% increase in Yanacocha revenues.

2Q21 gold production at Tambomayo increased 5% year on year, primarily due to a 15% increase in ore milled after accounting for treated stockpiles.

Cost Applicable to Sales (CAS) increased to 873 US$/Oz in 2Q21, from 736 US$/Oz in 2Q20, primarily due to a 164% increase in exploration expenses.

2Q21 silver production at Uchucchacua increased by 30%, primarily due to an increase in ore treated. Uchucchacua did not achieve full capacity during the second quarter 2021 due to mine development delays and lower than expected grades from planned stopes. Production was also adversely affected by a reduced workforce during 2021 due to continued COVID-19 related personnel restrictions. 2Q21 Cost Applicable to Sales (CAS) increased by 73% year on year, mainly due to an increase in commercial deductions, exploration expenses and additional COVID-19 expenses to comply with sanitary protocols.

El Brocal 2Q21 copper production increased by 245% year on year, mainly due to a 316% increase in ore milled at Marcapunta during the quarter and additional copper ore derived from the Tajo Norte mine. Tajo Norte 2Q21 zinc production increased by 96% year on year due to a year on year increase in ore treated.

2Q21 Copper Cost Applicable to Sales (CAS) increased by 14% year on year, mainly due to a US$ 2 million increase in exploration expenses in order to offset the reduced exploration activities during 2Q20. 2Q21 zinc CAS increased by 4% year on year.

General and Administrative Expenses

2Q21 General and Administrative expenses were US$ 16.1 million; an 8% increase as compared to US$ 14.9 million in 2Q20.

Exploration in Non-Operating Areas

2Q21 exploration costs in Non-Operating Areas were US$ 2.0 million, compared with US$ 1.7 million in 2Q20. During the period, Buenaventura focused exploration primarily on its Emperatriz project, resulting in US$ 0.7 million in exploration costs during 2Q21. The increase in exploration during the quarter is in line with Buenaventura’s Strategy to focus on extending LOM.

Financial Expenses

2Q21 financial expenses increased due to higher interest generated by Letters of Guarantee (2.5%) related fees. Said letters will be returned and deactivated in early August due to the Company’s payment in full on July 30, 2021 of all outstanding debt owed to SUNAT.

Cerro Verde reported 2Q21 net income of US$ 240.3 million, compared to net income of US$ 68.7 million in 2Q20.

Compañía de Minas Buenaventura S.A.A.<br><br> <br>Second Quarter 2021 Results<br><br> <br>Page 13 of 27

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 (Yanacocha) (2) Buenaventura’s equity share of EBITDA (Cerro Verde), plus (3) 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 Sales and 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 nine months ended September 30, 2015 and 2016, 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 nine months ended September 30, 2015 and 2016 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.
