FIRST QUARTER 2021 FINANCIAL AND PRODUCTION SUMMARY

Attributable gold production ¹ was in line compared to the prior year quarter, decreasing 2 percent to 1,455 thousand ounces primarily due to the sale of Red Lake, lower leach pad production and the ramp down of the mill at Yanacocha, lower mill throughput at Nevada Gold Mines, lower ore grade milled at Merian and lower production at Cerro Negro as the site focuses on returning operations to full capacity while managing ongoing Covid-related impacts. These decreases were largely offset by higher ore grade milled at Peñasquito, Musselwhite, Boddington and Akyem.

Gold CAS ² improved 7 percent to $1,065 million from the prior year quarter primarily due to lower ounces sold. Gold CAS per ounce improved 4 percent to $752 per ounce primarily due to higher by-product credits from higher realized metal prices and lower stockpile and leach-pad inventory adjustments, partially offset by higher gold price-driven royalties and lower ounces sold.

Gold AISC ³ remained flat compared to the prior year quarter at $1,039 per ounce as higher sustaining capital spend and higher advanced projects spend were largely offset by lower CAS per ounce.

Attributable gold equivalent ounce (GEO) production from other metals decreased 6 percent to 317 thousand ounces primarily due to lower ore grade milled at Peñasquito, partially offset by higher grade and throughput at Boddington.

CAS from other metals totaled $182 million for the quarter. CAS per GEO ² improved 8 percent to $555 per ounce from the prior year quarter primarily due to a lower allocation of costs to other metals and higher sales at Peñasquito, partially offset by unfavorable foreign currency impacts from the strengthening of the Australian dollar and higher copper price-driven royalties at Boddington. AISC per GEO ³ improved 5 percent to $819 per ounce primarily due to lower CAS from other metals, partially offset by higher sustaining capital spend.

Net income from continuing operations attributable to Newmont stockholders was $538 million or $0.67 per diluted share, a decrease of $299 million from the prior year quarter primarily due to the recognized gains on the sales of Kalgoorlie, Red Lake and investment holdings in Continental Gold, Inc. (Continental) in the prior year, higher income tax expense and lower sales volumes in the current year. These decreases were partially offset by higher average realized prices in the current year, the impairment charge of TMAC Resources, Inc. (TMAC) in the prior year and charges from debt extinguishment in the prior year.

Adjusted net income ⁴ was $594 million or $0.74 per diluted share, compared to $326 million or $0.40 per diluted share in the prior year quarter. Primary adjustments to first quarter net income include changes in the fair value of investments, gains on asset and investment sales, reclamation and remediation charges and valuation allowance and other tax adjustments.

Adjusted EBITDA ⁵ improved 30 percent to $1,457 million for the quarter, compared to $1,118 million for the prior year quarter.

Revenue increased 11 percent from the prior year quarter to $2,872 million primarily due to higher average realized metal prices, partially offset by lower sales volumes.

Average realized price ⁶ for gold was $1,751, an increase of $160 per ounce over the prior year quarter. Average realized gold price includes $1,780 per ounce of gross price received, the unfavorable impact of $20 per ounce mark-to-market on provisionally-priced sales and reductions of $9 per ounce for treatment and refining charges.

Capital expenditures ⁷ increased 22 percent from the prior year quarter to $399 million primarily due to higher sustaining capital spend from Boddington Autonomous Haulage and higher development capital spend. Development capital expenditures in 2021 primarily include advancing Tanami Expansion 2, Yanacocha Sulfides, Cerro Negro expansion projects, Ahafo North, the Subika Mining Method Change, Quecher Main and projects associated with the Company's ownership interest in Nevada Gold Mines.

Consolidated operating cash flow from continuing operations decreased 10 percent from the prior year quarter to $841 million primarily due to higher tax payments and other net unfavorable working capital movements , partially offset by higher average realized metal prices. Free Cash Flow ⁸ also decreased to $442 million primarily due to lower operating cash flow and higher capital expenditures as described above.

Balance sheet ended the quarter with $5.5 billion of consolidated cash and approximately $8.5 billion of liquidity; reported net debt to adjusted EBITDA of 0.2x ⁹ .

Nevada Gold Mines (NGM) attributable gold production was 303 thousand ounces with CAS of $745 per ounce and AISC of $868 per ounce for the first quarter. EBITDA ¹⁰ for NGM was $294 million.

Pueblo Viejo (PV) attributable gold production was 91 thousand ounces for the quarter. Pueblo Viejo EBITDA ¹⁰ was $117 million and cash distributions received for the Company's equity method investment totaled $38 million in the first quarter.

COVID-19 UPDATE

Newmont continues to maintain wide-ranging protective measures for its workforce and neighboring communities, including screening, physical distancing, deep cleaning and avoiding exposure for at-risk individuals. The Company incurred incremental Covid specific costs of $22 million during the quarter for activities such as additional health and safety procedures, increased transportation and community fund contributions. During the second quarter of 2020, the Newmont Global Community Support Fund was established to help host communities, governments and employees combat the Covid pandemic. Amounts distributed from this fund were $1 million during the quarter and have been adjusted from certain non-GAAP metrics. The remaining $21 million is not adjusted from our non-GAAP metrics.

We have mobilized a Covid vaccine working group with representatives from across the globe. Newmont views vaccination as critical in the fight against Covid-19 and actively encourages our workforce to get vaccinated as they become eligible. We are working to support authorities, through our Global Community Support Fund, to improve the availability and deployment of vaccines to our workforce and host communities.

PROJECTS UPDATE

Newmont's capital-efficient project pipeline supports improving production, lowering costs and extending mine life. Funding for the current development capital project Tanami Expansion 2 has been approved and the project is in execution stage. The Company has included the Ahafo North and Yanacocha Sulfides projects in its long-term outlook as the projects are scheduled to be approved for full funding in 2021. Additional sustaining and development projects, not listed below, represent incremental improvements to the Company's outlook.

• Tanami Expansion 2 (Australia) secures Tanami's future as a long-life, low-cost producer with potential to extend mine life beyond 2040 through the addition of a 1,460 meter hoisting shaft and supporting infrastructure to achieve 3.5 million tonnes per year of production and provide a platform for future growth. The expansion is expected to increase average annual gold production by approximately 150,000 to 200,000 ounces per year for the first five years and is expected to reduce operating costs by approximately 10 percent. Capital costs for the project are estimated to be between $850 million and $950 million with a commercial production date in the first half of 2024.

• Ahafo North (Africa) expands our existing footprint in Ghana with four open pit mines and a stand-alone mill located approximately 30 kilometers from the Company's Ahafo South operations. An investment decision is expected in July 2021 and the project is expected to add 300,000 ounces per year with all-in sustaining costs between $600 to $700 per ounce for the first five full years of production (2024-2028), with estimated capital costs of between $700 and $800 million. Ahafo North is the best unmined gold deposit in West Africa with approximately 3.5 million ounces of Reserves and more than 1 million ounces of Measured and Indicated and Inferred Resource ¹¹ and significant upside potential to extend beyond Ahafo North's current 13-year mine life.

• Yanacocha Sulfides (South America) ¹² will develop the first phase of sulfide deposits and an integrated processing circuit, including an autoclave to process gold, copper and silver feedstock. The project is expected to add 500,000 gold equivalent ounces per year with all-in sustaining costs between $700 to $800 per ounce for the first five full years of production (2026-2030). An investment decision is expected in the second half of 2021 with a three year development period and estimated capital costs of approximately $2 billion. The first phase focuses on developing the Yanacocha Verde and Chaquicocha deposits to extend Yanacocha's operations beyond 2040 with second and third phases having the potential to extend life for multiple decades.

OUTLOOK

Newmont's outlook reflects increasing gold production and ongoing investment in its operating assets and most promising growth prospects. The Company has included Ahafo North and Yanacocha Sulfides in its outlook as the development projects are expected to reach execution stage in 2021. Additional development projects that have not reached execution stage represent upside to guidance. All production, cost and capital figures assume a $1,200/oz gold price.

Newmont's 2021 and longer-term outlook assumes operations continue without major Covid-related interruptions. If at any point the Company determines that continuing operations poses an increased risk to our workforce or host communities, it will reduce operational activities up to, and including, care and maintenance and management of critical environmental systems. Please see cautionary statement in the end notes for additional information.

2021 Regional Outlook ^a

^a 2021 regional outlook projections used in this presentation are considered forward-looking statements and represent management's good faith estimates or expectations of future production results as of December 8, 2020. Outlook is based upon certain assumptions, including, but not limited to, metal prices, oil prices, certain exchange rates and other assumptions. For example, 2021 Outlook assumes $1,200/oz Au, $22/oz Ag, $2.75/lb Cu, $1.05/lb Zn, $0.90/lb Pb, $0.75 USD/AUD exchange rate, $0.77 USD/CAD exchange rate and $50/barrel WTI; AISC and CAS estimates do not include inflation, for the remainder of the year. Production, CAS, AISC and capital estimates exclude projects that have not yet been approved, except for Ahafo North and Yanacocha Sulfides which are included in Outlook as the development projects are expected to reach execution stage in 2021. The potential impact on inventory valuation as a result of lower prices, input costs, and project decisions are not included as part of this Outlook. Assumptions used for purposes of Outlook may prove to be incorrect and actual results may differ from those anticipated, including variation beyond a +/-5% range. Outlook cannot be guaranteed. As such, investors are cautioned not to place undue reliance upon Outlook and forward-looking statements as there can be no assurance that the plans, assumptions or expectations upon which they are placed will occur. Amounts may not recalculate to totals due to rounding. See cautionary at the end of this release.
^b All-in sustaining costs or AISC as used in the Company's Outlook is a non-GAAP metric; see below for further information and reconciliation to consolidated 2021 CAS outlook.
^c Represents the ownership interest in the Nevada Gold Mines (NGM) joint venture. NGM is owned 38.5% by Newmont and owned 61.5% and operated by Barrick. The Company accounts for its interest in NGM using the proportionate consolidation method, thereby recognizing its pro-rata share of the assets, liabilities and operations of NGM. Production, CAS and AISC for the Company's 38.5% ownership interest in NGM as provided by Barrick Gold Corporation based on a $1,200/oz gold price assumption.
^d Attributable gold production outlook includes the Company's equity investment (40%) in Pueblo Viejo with ~325Koz in 2021; does not include the Company's other equity investments. Attributable gold production outlook represents the Company's 51.35% interest for Yanacocha and a 75% interest for Merian.
^e Total sustaining capital includes ~$20 million of corporate and other spend.
^f Gold equivalent ounces (GEO) is calculated as pounds or ounces produced multiplied by the ratio of the other metal's price to the gold price, using Gold ($1,200/oz.), Copper ($2.75/lb.), Silver ($22/oz.), Lead ($0.90/lb.), and Zinc ($1.05/lb.) pricing.
^g The adjusted tax rate excludes certain items such as tax valuation allowance adjustments.
^h Assuming average prices of $1,500 per ounce for gold, $22 per ounce for silver, $2.75 per pound for copper, $0.90 per pound for lead, and $1.05 per pound for zinc and achievement of current production and sales volumes and cost estimates, we estimate our consolidated adjusted effective tax rate related to continuing operations for 2021 will be between 34%-38%.

Non-GAAP Financial Measures

Non-GAAP financial measures are intended to provide additional information only and do not have any standard meaning prescribed by U.S. generally accepted accounting principles ("GAAP"). These measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Unless otherwise noted, we present the Non-GAAP financial measures of our continuing operations in the tables below.

Adjusted net income (loss)

Management uses Adjusted net income (loss) to evaluate the Company's operating performance and for planning and forecasting future business operations. The Company believes the use of Adjusted net income (loss) allows investors and analysts to understand the results of the continuing operations of the Company and its direct and indirect subsidiaries relating to the sale of products, by excluding certain items that have a disproportionate impact on our results for a particular period. Adjustments to continuing operations are presented before tax and net of our partners' noncontrolling interests, when applicable. The tax effect of adjustments is presented in the Tax effect of adjustments line and is calculated using the applicable regional tax rate. Management's determination of the components of Adjusted net income (loss) are evaluated periodically and based, in part, on a review of non-GAAP financial measures used by mining industry analysts. Net income (loss) attributable to Newmont stockholders is reconciled to Adjusted net income (loss) as follows:

Earnings before interest, taxes and depreciation and amortization and Adjusted earnings before interest, taxes and depreciation and amortization

Management uses Earnings before interest, taxes and depreciation and amortization ("EBITDA") and EBITDA adjusted for non-core or certain items that have a disproportionate impact on our results for a particular period ("Adjusted EBITDA") as non-GAAP measures to evaluate the Company's operating performance. EBITDA and Adjusted EBITDA do not represent, and should not be considered an alternative to, net income (loss), operating income (loss), or cash flow from operations as those terms are defined by GAAP, and do not necessarily indicate whether cash flows will be sufficient to fund cash needs. Although Adjusted EBITDA and similar measures are frequently used as measures of operations and the ability to meet debt service requirements by other companies, our calculation of Adjusted EBITDA is not necessarily comparable to such other similarly titled captions of other companies. The Company believes that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and Board of Directors. Management's determination of the components of Adjusted EBITDA are evaluated periodically and based, in part, on a review of non-GAAP financial measures used by mining industry analysts. Net income (loss) attributable to Newmont stockholders is reconciled to EBITDA and Adjusted EBITDA as follows:

Additionally, the Company uses Pueblo Viejo EBITDA as a non-GAAP measure to evaluate the operating performance of its investment in the Pueblo Viejo mine. Pueblo Viejo EBITDA does not represent, and should not be considered an alternative to, Equity income (loss) of affiliates, as defined by GAAP, and does not necessarily indicate whether cash distributions from Pueblo Viejo will match Pueblo Viejo EBITDA or earnings from affiliates. Although the Company has the ability to exert significant influence, it does not have direct control over the operations or resulting revenues and expenses, nor does it proportionately consolidate its investment in Pueblo Viejo. The Company believes that Pueblo Viejo EBITDA provides useful information to investors and others in understanding and evaluating the operating results of its investment in Pueblo Viejo, in the same manner as management and the Board of Directors. Equity income (loss) of affiliates is reconciled to Pueblo Viejo EBITDA as follows:​

The Company uses NGM EBITDA as a non-GAAP measure to evaluate the operating performance of its investment in Nevada Gold Mines (NGM). NGM EBITDA does not represent, and should not be considered an alternative to, Income (loss) before income and mining tax and other items, as defined by GAAP, and does not necessarily indicate whether cash distributions from NGM will match NGM EBITDA. Although the Company has the ability to exert significant influence and proportionally consolidates its 38.5% interest in NGM, it does not have direct control over the operations or resulting revenues and expenses of its investment in NGM. The Company believes that NGM EBITDA provides useful information to investors and others in understanding and evaluating the operating results of its investment in NGM, in the same manner as management and the Board of Directors. Income (loss) before income and mining tax and other items is reconciled to NGM EBITDA as follows:

Free Cash Flow

Management uses Free Cash Flow as a non-GAAP measure to analyze cash flows generated from operations. Free Cash Flow is Net cash provided by (used in) operating activities less Net cash provided by (used in) operating activities of discontinued operations less Additions to property, plant and mine development as presented on the Condensed Consolidated Statements of Cash Flows. The Company believes Free Cash Flow is also useful as one of the bases for comparing the Company's performance with its competitors. Although Free Cash Flow and similar measures are frequently used as measures of cash flows generated from operations by other companies, the Company's calculation of Free Cash Flow is not necessarily comparable to such other similarly titled captions of other companies.

The presentation of non-GAAP Free Cash Flow is not meant to be considered in isolation or as an alternative to net income as an indicator of the Company's performance, or as an alternative to cash flows from operating activities as a measure of liquidity as those terms are defined by GAAP, and does not necessarily indicate whether cash flows will be sufficient to fund cash needs. The Company's definition of Free Cash Flow is limited in that it does not represent residual cash flows available for discretionary expenditures due to the fact that the measure does not deduct the payments required for debt service and other contractual obligations or payments made for business acquisitions. Therefore, the Company believes it is important to view Free Cash Flow as a measure that provides supplemental information to the Company's Condensed Consolidated Statements of Cash Flows.

The following table sets forth a reconciliation of Free Cash Flow, a non-GAAP financial measure, to Net cash provided by (used in) operating activities , which the Company believes to be the GAAP financial measure most directly comparable to Free Cash Flow, as well as information regarding Net cash provided by (used in) investing activities and Net cash provided by (used in) financing activities.

Attributable Free Cash Flow

Management uses Attributable Free Cash Flow as a non-GAAP measure to analyze cash flows generated from operations that are attributable to the Company. Attributable Free Cash Flow is Net cash provided by (used in) operating activities after deducting net cash flows from operations attributable to noncontrolling interests less Net cash provided by (used in) operating activities of discontinued operations after deducting net cash flows from discontinued operations attributable to noncontrolling interests less Additions to property, plant and mine development after deducting property, plant and mine development attributable to noncontrolling interests. The Company believes that Attributable Free Cash Flow is useful as one of the bases for comparing the Company's performance with its competitors. Although Attributable Free Cash Flow and similar measures are frequently used as measures of cash flows generated from operations by other companies, the Company's calculation of Attributable Free Cash Flow is not necessarily comparable to such other similarly titled captions of other companies.

The presentation of non-GAAP Attributable Free Cash Flow is not meant to be considered in isolation or as an alternative to Net income attributable to Newmont stockholders as an indicator of the Company's performance, or as an alternative to Net cash provided by (used in) operating activities as a measure of liquidity as those terms are defined by GAAP, and does not necessarily indicate whether cash flows will be sufficient to fund cash needs. The Company's definition of Attributable Free Cash Flow is limited in that it does not represent residual cash flows available for discretionary expenditures due to the fact that the

measure does not deduct the payments required for debt service and other contractual obligations or payments made for business acquisitions. Therefore, the Company believes it is important to view Attributable Free Cash Flow as a measure that provides supplemental information to the Company's Condensed Consolidated Statements of Cash Flows.

The following tables set forth a reconciliation of Attributable Free Cash Flow, a non-GAAP financial measure, to Net cash provided by (used in) operating activities , which the Company believes to be the GAAP financial measure most directly comparable to Attributable Free Cash Flow, as well as information regarding Net cash provided by (used in) investing activities and Net cash provided by (used in) financing activities.

Costs applicable to sales per ounce/gold equivalent ounce

Costs applicable to sales per ounce/gold equivalent ounce are non-GAAP financial measures. These measures are calculated by dividing the costs applicable to sales of gold and other metals by gold ounces or gold equivalent ounces sold, respectively. These measures are calculated for the periods presented on a consolidated basis. Costs applicable to sales per ounce/gold equivalent ounce statistics are intended to provide additional information only and do not have any standardized meaning prescribed by GAAP and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The measures are not necessarily indicative of operating profit or cash flow from operations as determined under GAAP. Other companies may calculate these measures differently.

The following tables reconcile these non-GAAP measures to the most directly comparable GAAP measures.

Costs applicable to sales per ounce

Costs applicable to sales per gold equivalent ounce

Costs applicable to sales per ounce for Nevada Gold Mines (NGM)

All-In Sustaining Costs

Newmont has developed a metric that expands on GAAP measures, such as cost of goods sold, and non-GAAP measures, such as costs applicable to sales per ounce, to provide visibility into the economics of our mining operations related to expenditures, operating performance and the ability to generate cash flow from our continuing operations.

Current GAAP measures used in the mining industry, such as cost of goods sold, do not capture all of the expenditures incurred to discover, develop and sustain production. Therefore, we believe that all-in sustaining costs is a non-GAAP measure that provides additional information to management, investors and analysts that aid in the understanding of the economics of our operations and performance compared to other producers and provides investors visibility by better defining the total costs associated with production.

All-in sustaining cost ("AISC") amounts are intended to provide additional information only and do not have any standardized meaning prescribed by GAAP and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The measures are not necessarily indicative of operating profit or cash flow from operations as determined under GAAP. Other companies may calculate these measures differently as a result of differences in the underlying accounting principles, policies applied and in accounting frameworks such as in International Financial Reporting Standards ("IFRS"), or by reflecting the benefit from selling non-gold metals as a reduction to AISC. Differences may also arise related to definitional differences of sustaining versus development (i.e. non-sustaining) activities based upon each company's internal policies.

The following disclosure provides information regarding the adjustments made in determining the All-in sustaining costs measure:

Costs applicable to sales . Includes all direct and indirect costs related to current production incurred to execute the current mine plan. We exclude certain exceptional or unusual amounts from Costs applicable to sales ("CAS"), such as significant revisions to recovery amounts. CAS includes by-product credits from certain metals obtained during the process of extracting and processing the primary ore-body. CAS is accounted for on an accrual basis and excludes Depreciation and amortization and Reclamation and remediation , which is consistent with our presentation of CAS on the Condensed Consolidated Statements of Operations. In determining AISC, only the CAS associated with producing and selling an ounce of gold is included in the measure. Therefore, the amount of gold CAS included in AISC is derived from the CAS presented in the Company's Condensed Consolidated Statements of Operations less the amount of CAS attributable to the production of other metals at our Peñasquito and Boddington mines. The other metals CAS at those mine sites is disclosed in Note 3 to the Condensed Consolidated Financial Statements. The allocation of CAS between gold and other metals at the Peñasquito and Boddington mines is based upon the relative sales value of gold and other metals produced during the period.

Reclamation costs . Includes accretion expense related to reclamation liabilities and the amortization of the related Asset Retirement Cost ("ARC") for the Company's operating properties. Accretion related to the reclamation liabilities and the amortization of the ARC assets for reclamation does not reflect annual cash outflows but are calculated in accordance with GAAP. The accretion and amortization reflect the periodic costs of reclamation associated with current production and are therefore included in the measure. The allocation of these costs to gold and other metals is determined using the same allocation used in the allocation of CAS between gold and other metals at the Peñasquito and Boddington mines.

Advanced projects, research and development and exploration . Includes incurred expenses related to projects that are designed to sustain current production and exploration. We note that as current resources are depleted, exploration and advanced projects are necessary for us to replace the depleting reserves or enhance the recovery and processing of the current reserves to sustain production at existing operations. As these costs relate to sustaining our production, and are considered a continuing cost of a mining company, these costs are included in the AISC measure. These costs are derived from the Advanced projects, research and development and Exploration amounts presented in the Condensed Consolidated Statements of Operations less incurred expenses related to the development of new operations, or related to major projects at existing operations where these projects will materially benefit the operation in the future. The allocation of these costs to gold and other metals is determined using the same allocation used in the allocation of CAS between gold and other metals at the Peñasquito and Boddington mines.

General and administrative . Includes costs related to administrative tasks not directly related to current production, but rather related to support our corporate structure and fulfill our obligations to operate as a public company. Including these expenses in the AISC metric provides visibility of the impact that general and administrative activities have on current operations and profitability on a per ounce basis.

Other expense, net . We exclude certain exceptional or unusual expenses, such as restructuring, as these are not indicative to sustaining our current operations. Furthermore, this adjustment to Other expense, net is also consistent with the nature of the adjustments made to Net income (loss) attributable to Newmont stockholders as disclosed in the Company's non-GAAP financial measure Adjusted net income (loss). The allocation of these costs to gold and other metals is determined using the same allocation used in the allocation of CAS between gold and other metals at the Peñasquito and Boddington mines.

Treatment and refining costs . Includes costs paid to smelters for treatment and refining of our concentrates to produce the salable metal. These costs are presented net as a reduction of Sales on our Condensed Consolidated Statements of Operations. The allocation of these costs to gold and other metals is determined using the same allocation used in the allocation of CAS between gold and other metals at the Peñasquito and Boddington mines.

Sustaining capital and finance lease payments . We determined sustaining capital and finance lease payments as those capital expenditures and finance lease payments that are necessary to maintain current production and execute the current mine plan. We determined development (i.e. non-sustaining) capital expenditures and finance lease payments to be those payments used to develop new operations or related to projects at existing operations where those projects will materially benefit the operation and are excluded from the calculation of AISC. The classification of sustaining and development capital projects and finance leases is based on a systematic review of our project portfolio in light of the nature of each project. Sustaining capital and finance lease payments are relevant to the AISC metric as these are needed to maintain the Company's current operations and provide improved transparency related to our ability to finance these expenditures from current operations. The allocation of these costs to gold and other metals is determined using the same allocation used in the allocation of CAS between gold and other metals at the Peñasquito and Boddington mines.
