NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(In thousands of United States dollars, except share amounts)

1. Basis of Presentation

Basis of Consolidation and Presentation

The financial statements represent the condensed consolidated financial position and results of operations of Gatos Silver, Inc. and its subsidiaries, Gatos Silver Canada Corporation and Minera Luz del Sol S. de R.L. de C.V. Unless the context otherwise requires, references to “Gatos Silver” or the “Company” mean Gatos Silver, Inc. and its consolidated subsidiaries.

The interim condensed consolidated financial statements are unaudited, but include all adjustments, consisting of normal recurring entries, which are necessary for a fair presentation for the dates and periods presented. Interim results are not necessarily indicative of results for a full year. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Accordingly, they do not include all financial information and disclosures required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission (“the SEC”) on February 20, 2024, as amended by Amendment No 1. on Form 10-K/A filed with the SEC on May 6, 2024 (as amended, the “2023 10-K”).

2. Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

The consolidated financial statements for the year ended December 31, 2023, disclose those accounting policies considered significant in determining results of operations and financial position. There have been no material changes to, or in the application of, the accounting policies previously identified and described in the 2023 10-K.

Recent Accounting Pronouncements

In March 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2024-02, Codification Improvements: Amendments to Remove References to the Concepts Statements. This ASU contains amendments to the Accounting Standards Codification (the "ASC") that remove references to various FASB Concepts Statements. The FASB has a standing project on its agenda to address suggestions received from stakeholders on the ASC and other incremental improvements to GAAP. This effort facilitates ASC updates for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or the structure of guidance, and other minor improvements. The resulting amendments are referred to as ASC improvements. The amendments of this update are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is still assessing the impact of this ASU, but does not expect it to have a material impact on the financial statements.

In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The amendments in this ASU modify the disclosure or presentation requirements of a variety of Topics in the ASC. Certain amendments represent clarifications to or technical corrections of the current requirements. Each amendment in this ASU will only become effective if the SEC removes the related disclosure or presentation requirement from its existing regulations by June 30, 2027. The Company is still assessing the impact of the standard.

There have been no other accounting pronouncements issued or adopted during the six months ended June 30, 2024, which are expected to have a material impact on the financial statements.

Stock option activity for the six months ended June 30, 2024, is summarized in the following tables:


Employee & Director Options	Number of options	Weighted‑ Average Exercise Price
Outstanding at December 31, 2023	2,616,515	$	8.83
Granted	647,753	$	6.70
Exercised	(46,285)	$	8.32
Forfeited	(17,818)	$	6.82
Expired	(9,946)	$	11.62
Outstanding at June 30, 2024	3,190,219	$	8.24
Vested at June 30, 2024	2,071,738	$	9.48

The following assumptions were used to compute the fair value of the options granted using the Black-Scholes option valuation model:


	April 2024		January 2024
Risk-free interest rate	4.56	%	3.86	%
Dividend yield	—		—
Estimated volatility	58.42	%	58.00	%

At June 30, 2024, the Company had 32,393 stock options previously granted to LGJV-personnel outstanding with a weighted-average exercise price of $7.31 and a weighted-average remaining life of 1.8 years. There were no grants or exercises related to LGJV-personnel during the three and six months ended June 30, 2024 and 2023.

Performance Share Unit ("PSU") Transactions

On December 17, 2021, 119,790 PSUs were granted to the Company’s employees with a weighted-average grant date fair value per share of $14.22. At June 30, 2024, there were 40,802 PSUs outstanding. On June 30, 2024, unrecognized compensation expense related to the PSUs was $75, which is expected to be recognized over a weighted-average period of 0.5 years.

Table of Contents

Restricted Stock Unit ("RSU") Transactions

RSUs granted are reported as equity awards with a fair value of each RSU equal to the fair value of the Company's common stock on the grant date. Each earned RSU represents the right to receive one share of the Company's common stock, subject to the terms of the grant agreement, and generally vest on or before the third year-end following the grant date.

The following table summarizes the RSU activity for the six months ended June 30, 2024:


Employee RSUs	Number of RSUs	Weighted‑ Average Price Per Share
Outstanding at December 31, 2023	925,172	$	5.04
Granted	323,875	$	6.70
Settled	(300,729)	$	5.04
Forfeited	(11,948)	$	5.50

Outstanding at June 30, 2024	936,370	$	5.61

The Company granted 27,500 and 323,875 RSUs during the three and six months ended June 30, 2024, with weighted-average grant-date fair values per share of $9.80 and $6.70, respectively. There were no RSUs granted during the three and six months ended June 30, 2023. Compensation expense is recognized ratably from the grant date over the requisite vesting period. On June 30, 2024, unrecognized compensation expense related to the RSUs was $3,845, which is expected to be recognized over a weighted-average period of 1.8 years.

Deferred Stock Unit ("DSU") Transactions

DSUs are awarded to directors at the discretion of the Company's Board of Directors. The DSUs are fully vested on the grant date and each DSU entitles the holder to receive one share of the Company’s common stock upon the director’s cessation of continuous service. Non-employee directors are eligible to elect to defer receipt of any portion of annual retainers or meeting fees and take payment in the form of DSUs. The fair value of the DSUs is equal to the fair value of the Company’s common stock on the grant date.

The following table summarizes the DSU activity for the six months ended June 30, 2024:


Employee and Director DSUs	Number of DSUs	Weighted‑ Average Price per Share
Outstanding at December 31, 2023	302,920	$	7.76
Granted	1,639	$	9.30
Outstanding at June 30, 2024	304,559	$	7.77

7. Net Income per Share

Basic net income per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed similarly, except that weighted-average common shares are increased to reflect the potential dilution that would occur if in-the-money stock options were exercised or common shares were issued upon settlement of PSUs, DSUs or RSUs. The dilutive effects are calculated using the treasury stock method.

For the three and six months ended June 30, 2024, weighted average outstanding in-the-money stock options, PSUs, RSUs and DSUs are included in dilutive earnings per common share calculation. For the three and six months ended June 30, 2023, the Company experienced a net loss; therefore, all stock awards have been excluded from the diluted earnings per share calculation as they were anti-dilutive.

A reconciliation of basic and diluted earnings per common share for the three and six months ended June 30, 2024 and 2023, is as follows:

Table of Contents


	Three Months Ended June 30,				Six Months Ended June 30,

Net income (loss) per share:
Basic and Diluted	$	0.13	$	(0.05)	$	0.17	$	(0.04)

8. Fair Value Measurements

The Company establishes a framework for measuring the fair value of assets and liabilities in the form of a fair value hierarchy that prioritizes the inputs into valuation techniques used to measure fair value into three broad levels. This hierarchy gives the highest priority to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs. Further, financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement. The three levels of the fair value hierarchy are as follows:

Level 1: Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.

Level 2: Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data.

Level 3: Unobservable inputs due to the fact there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability.

Assets and Liabilities that are Measured at Fair Value on a Non-recurring Basis

The Company discloses and recognizes its non-financial assets and liabilities at fair value on a non-recurring basis and makes adjustments to fair value, as needed (for example, when there is evidence of impairment).

The Company recorded its initial investment in affiliates at fair value within Level 3 of the fair value hierarchy, as the valuation was determined based on internally developed assumptions with few observable inputs and no market activity.

9. Commitments, Contingencies and Guarantees

In determining its accruals and disclosures with respect to loss contingencies, the Company will charge to income an estimated loss if information available prior to the issuance of the condensed consolidated financial statements indicates that it is probable that a liability has been incurred at the date of the condensed consolidated financial statements and the amount of the loss can be reasonably estimated. Legal expenses associated with the commitments and contingencies are expensed as incurred.

Environmental Contingencies

The Company’s mining and exploration activities are subject to various laws, regulations and permits governing the protection of the environment. These laws, regulations and permits are continually changing and are generally becoming more restrictive. The Company has made, and expects to make in the future, expenditures to comply with such laws, regulations and permits, but cannot predict the full amount of such future expenditures.

Legal

On February 22, 2022, a purported Company stockholder filed a putative class action lawsuit in the United States District Court for the District of Colorado (the "District Court") against the Company, certain of our former officers, and several directors (the "U.S. Class Action"). An amended complaint was filed on August 15, 2022. The amended complaint, allegedly brought on behalf of certain purchasers of the Company’s common stock and certain traders of call and put options on the Company’s common stock from December 9, 2020 through January 25, 2022, seeks, among other things, damages, costs, and expenses, and asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 as well as Sections 11 and 15 of the Securities Act of 1933. The amended complaint alleges that certain individual defendants and the Company, pursuant to the control and authority of the individual defendants, made false and misleading statements and/or omitted certain material information regarding the mineral resources and reserves at the Cerro Los Gatos mine. The Company and all defendants filed a motion to dismiss this action on October 14, 2022. That motion was fully briefed as of December 23, 2022. On April 26, 2023, following a joint motion, the District Court postponed its ruling on the defendants’ motion to dismiss until on or after June 16, 2023.

On June 13, 2023, the Company entered into an agreement in principle to settle the U.S. Class Action. Subject to certain conditions, including class certification by the District Court, the execution of a definitive stipulation of settlement and approval of the settlement by the District Court, the settling parties agreed to resolve the U.S. Class Action for an aggregate payment by the Company and its insurers of $21,000 to a settlement fund. On June 16, 2023, the parties filed a joint status report requesting that the District Court grant a temporary stay of all proceedings in the case pending submission of proposed settlement documentation on or before July 13, 2023. On July 13, 2023, the plaintiffs filed an unopposed motion for an order preliminarily approving a stipulation of settlement agreed by the parties and providing for class notice which will provide for (i) preliminary approval of the settlement; (ii) approval of the form and manner of giving notice of the settlement to the settlement class; and (iii) a hearing date and time to consider final and approval of the settlement and related matters (the “Preliminary Order”). On September 12, 2023, the plaintiffs filed an unopposed motion to amend the Preliminary Order to reflect certain changes to the form of release proposed to be executed by the plaintiffs.

The District Court issued its Preliminary Order on February 29, 2024, approving the proposed settlement. Consistent with the stipulation of settlement requiring that a settlement account be funded within 30 days of the Preliminary Order, the Company and its insurers have fully funded that account, with $1,403 funded by the Company and $19,597 funded by the Company’s insurers. The final fairness hearing with the District Court was held on May 29, 2024. The final settlement remains subject to final court approval, and as a result, there can be no assurance that the U.S. Class Action will be resolved pursuant to the terms of the settlement agreement.

By Notice of Action issued February 9, 2022, and subsequent Statement of Claim dated March 11, 2022, Izabela Przybylska (the "Plaintiff") commenced a putative class action against the Company, certain of its former officers, and others in the Ontario Superior Court of Justice on behalf of a purported class of all persons or entities, wherever they may reside or be domiciled, who acquired securities of the Company in both the primary and secondary markets during the period from October 28, 2020 until January 25, 2022 (the “Canadian Class Action”). The action asserts claims under Canadian securities legislation and at common law and seeks unspecified monetary damages and other relief in respect of allegations the defendants made false and misleading statements and omitted material information regarding the mineral resources and reserves of the Company.

On January 26, 2024, counsel for the Company and counsel for the Plaintiff executed a term sheet wherein any claims against the Company and the named individuals would be settled for a payment by the Company of $3,000. Such counsel subsequently agreed to and executed a definitive settlement agreement. On April 16, 2024, the Ontario Superior Court approved the settlement on a preliminary basis. Consistent with the terms of the settlement requiring that an escrow account be funded within 30 days of preliminary court approval, the Company and its insurers have fully funded an escrow account, with $2,597 funded by the Company and $403 funded by the Company’s insurers. The final fairness hearing with the Ontario Superior Court was held on June 28, 2024, and the Ontario Superior Court issued orders approving the settlement.

The Company has made disclosures to the U.S. Department of Justice (the "DOJ") and the SEC regarding its January 25, 2022 press release and issues related to CLG’s mineral reserves and mineral resources at the time. The Company has been cooperating with those agencies’ investigations. The Company was advised on July 15, 2024, that the DOJ has closed its investigation in relation to the Company. The Company understands that the SEC's investigation has not been completed and cannot reasonably predict any outcome.

There can be no assurance that any of the foregoing matters individually or in aggregate will not result in outcomes that are materially adverse for the Company.

Gatos Silver

Three Months Ended June 30, 2024, Compared to Three Months Ended June 30, 2023

General and administrative expenses

The $1.7 million increase in general and administration expenses is primarily due to a $1.2 million increase in non-cash stock-based compensation expense, as a result of equity grants since September 2023, after an extended blackout period, and a $0.6 million increase in legal and consulting fees, which are not expected to be recurring beyond 2024. General and administrative expenses, net of non-cash stock-based compensation expense of $1.6 million for the three months ended June 30, 2024, was $6.3 million, compared to $5.7 million, net of $0.5 million of non-cash stock-based compensation expense in the prior period.

Equity income in affiliates

The increase in equity income resulted primarily from the LGJV reporting net income of $20.5 million for the three months ended June 30, 2024, compared to $0.7 million for the three months ended June 30, 2023. See “Results of operations LGJV” below.

Table of Contents

Interest income

The $1.0 million increase in interest income is attributed to higher cash balances during the period and higher interest rates on cash deposits.

Other income

Other income increased $0.4 million for the three months ended June 30, 2024, compared to the three months ended June 30, 2023, of which $0.3 million was due to increased LGJV management fees effective October 2023, and $0.1 million due to foreign exchange gains.

Net income (loss) and comprehensive income (loss)

For the three months ended June 30, 2024, the Company recorded net income and comprehensive income of $9.2 million, or $0.13 per share, compared to net loss and comprehensive loss of $3.6 million, or $0.05 loss per share, for the three months ended June 30, 2023. The increase is mainly due to the increase in equity income in affiliates and interest income, partly offset by an increase in general and administrative expenses.

Six Months Ended June 30, 2024, Compared to Six Months Ended June 30, 2023

General and administrative expenses

The $3.2 million increase in general and administrative expenses is primarily due to $2.3 million of non-cash stock-based compensation expense as a result of equity grants issued since September 2023, after an extended blackout period, and a $0.9 million increase in consulting and legal fees, which are not expected to be recurring beyond 2024. General and administrative expenses, net of non-cash stock-based compensation expense of $3.3 million for the six months ended June 30, 2024, was $11.5 million, compared to $10.5 million, net of $1.2 million of non-cash stock-based compensation expense in the prior period.

Equity income in affiliates

The $15.3 million increase in equity income is due to the increase in LGJV net income. The LGJV reported net income of $30.7 million for the six months ended June 30, 2024, compared to $13.4 million for the six months ended June 30, 2023. See “Results of operations LGJV” below.

Interest income

The $1.6 million increase in interest income is attributed to higher cash balances during the period and higher interest rates on cash deposits.

Other income

For the six months ended June 30, 2024 and 2023, other income consists primarily of $3.0 million and $2.5 million, respectively, in management fees the Company received from the LGJV, which increased by $1.0 million annually effective October 2023.

Net income (loss) and comprehensive income (loss)

For the six months ended June 30, 2024, the Company recorded net income and comprehensive income of $11.7 million, or $0.17 per share, compared to a net loss and comprehensive loss of $2.8 million, or $0.04 loss per share, for the six months ended June 30, 2023, mainly due to the increase in equity income in affiliates, partly offset by an increase in general and administrative expenses.

Three Months Ended June 30, 2024, Compared to Three Months Ended June 30, 2023

Revenue

The LGJV’s concentrate sales for the three months ended June 30, 2024 and 2023, are summarized below:


	Three Months Ended June 30,
(in thousands)	2024		2023
Lead concentrate revenue	$	64,808	$	49,966
Zinc concentrate revenue	31,061		15,345
Treatment and refining charges	(2,339)		(3,917)
Subtotal	93,530		61,394
Provisional revenue adjustments	668		(3,135)
Total Revenue	$	94,198	$	58,259

Revenue increased by 62% for the three months ended June 30, 2024, compared to the three months ended June 30, 2023. The increase in revenue is primarily due to increases in sales volumes of silver, zinc, lead and gold of 12%, 35%, 23% and 4%, respectively, and increases in the average realized prices of silver, zinc, lead and gold of 20%, 55%, 4% and 21%, respectively. Treatment and refining charges decreased by 40.3% due to lower treatment and refining rates. Provisional revenue adjustments account for commodity price fluctuations in concentrate sales that are still subject to final settlement.

Cost of sales

Cost of sales increased by 24% primarily due to a 29% increase in the tonnage of concentrates sold and associated higher mining and processing costs as a result of 11% higher mill throughput. Cost of sales was further impacted by the operating costs of the fluorine leaching plant commissioned in July 2023, and the strengthening of the Mexican peso against the U.S. dollar. Co-product cash cost1 per ounce of payable silver equivalent decreased to $11.83 due to higher payable silver, zinc and lead volumes, partly offset by higher cash costs. By-product cash cost1 per ounce of payable silver decreased to $0.96 due to higher payable silver volumes and significantly higher contribution from by-product that almost fully offset the higher cash costs.

Royalties and duties expense

Royalties and duties expense increased by $0.4 million for the three months ended June 30, 2024, compared to the same period in 2023 due to increased concentrate sales and mining duties during the current year period.

General and administrative expenses

General and administrative expenses for the three months ended June 30, 2024, were $0.3 million lower as compared to the three months ended June 30, 2023, primarily due to $0.6 million reduction in audit and consulting fees, offset by $0.3 million increase in management fees in the current period.

Depreciation, depletion and amortization

Depreciation, depletion, and amortization expense decreased by approximately 5% primarily due to the increase in mineral reserves and the extension of life of mine in July 2023. The reduced depreciation was partly offset by depreciation on the fluorine leaching plant commissioned in July 2023.

Exploration

Exploration expense for the three months ended June 30, 2024, was $0.9 million higher as compared to the three months ended June 30, 2023, primarily due to increased greenfields exploration. The second quarter also highlighted the shift in prioritization to explore the broader LGD, as drilling continued in Portigueño and commenced on both the Central Deeps and San Luis targets, coupled with detailed mapping and rock geochemistry sampling work in other areas.

Table of Contents

Other expense (income)

Other expense was $2.0 million for the three months ended June 30, 2024, compared to other income of $0.4 million for the three months ended June 30, 2023. The total change of $2.4 million is due to a $0.8 million loss on foreign exchange incurred for the three months ended June 30, 2024, compared to a foreign exchange gain of $0.2 million in the same period in 2023, a $1.0 million positive adjustment on VAT receivable balances, and a $0.3 million decrease in interest income in the second quarter 2024, compared to the same period of 2023.

Income tax expense

Income tax expense of $12.5 million was recorded for the three months ended June 30, 2024, compared to income tax expense of $4.7 million for the three months ended June 30, 2023. The 165% increase in income tax expense was primarily due to higher taxable income for the three months ended June 30, 2024.

Net income and comprehensive income

For the three months ended June 30, 2024, the LGJV had net income and comprehensive income of $20.5 million compared to $0.7 million for the three months ended June 30, 2023. The increase in net income and comprehensive income was primarily due to an increase in revenue and, to a lesser extent, the decrease in depreciation, depletion and amortization expense, partly offset by higher cost of sales, royalties and duties, exploration expense, income tax expense and other expenses for the three months ended June 30, 2024, compared to the same period of 2023.

Sustaining capital

For the three months ended June 30, 2024, sustaining capital expenditures primarily consisted of $6.3 million of mine development and $5.1 million of infrastructure and equipment, including $1.7 million for the overhaul of mining equipment. During the three months ended June 30, 2023, sustaining capital expenditures primarily consisted of $5.9 million of mine development and $7.2 million of infrastructure and equipment including construction of the fluorine leach plant.

Resource development drilling expenditures

For the three months ended June 30, 2024 and June 30, 2023 resource development drilling expenditures primarily related to resource expansion drilling of the South-East Deeps zone at CLG. The decrease in resource development drilling expenditures in the three months ended June 30, 2024, is primarily due to less infill drilling, compared to the same period in 2023.

Six Months Ended June 30, 2024, Compared to Six Months Ended June 30, 2023

Revenue

The LGJV’s concentrate sales for the six months ended June 30, 2024 and 2023, are summarized below, in thousands:


	Six Months Ended June 30,
(in thousands)		2024		2023
Lead concentrate revenue		$	122,402	$	114,944
Zinc concentrate revenue		50,521		37,997
Treatment and refining charges		(6,296)		(8,072)
Subtotal		166,627		144,869
Provisional revenue adjustments		(211)		(16,745)
Total Revenue		$	166,416	$	128,124

Total revenue increased by 30% for the six months ended June 30, 2024, compared to the six months ended June 30, 2023, primarily as a result of increases in metal prices and an increase in payable metals sold. Sales volumes of payable silver, zinc, lead and gold increased by 6%, 25%, 17% and 4%, respectively. The average realized prices of silver, zinc and gold increased by 1%, 9% and 14%, respectively, and the average realized lead price decreased by 8%. Treatment and refining charges decreased by 22% due to lower treatment and refining rates and provision revenue adjustment decreased by 99% due to an increase in future metal prices. Provisional revenue adjustments account for commodity price fluctuations in concentrate sales that are still subject to final settlement.

Table of Contents

Cost of sales

Cost of sales increased by 21% primarily due to a 23% increase in the tonnage of the concentrate sold and the associated higher mining and processing costs as a result of an 11% increase in mill throughput. Cost of sales was further impacted by the operating costs of the fluorine leaching plant commissioned in July 2023, and the strengthening of the Mexican peso against the U.S. dollar. Co-product cash cost1 per ounce of payable silver equivalent increased slightly to $11.70 due to higher cash costs that were partially offset by higher payable silver, zinc and lead volumes. By-product cash cost1 per ounce of payable silver decreased to $3.66 as higher cash costs were more than offset by a higher contribution from by-products and higher payable silver volumes.

Royalties and duties expense

Royalties and duties expense increased by $0.3 million for the six months ended June 30, 2024, due to increased concentrate sales and mining duties in 2024.

General and administrative expenses

General and administrative expenses for the six months ended June 30, 2024 are consistent with the same period in 2023.

Depreciation, depletion and amortization expense

Depreciation, depletion, and amortization expense decreased by 4% for the six months ended June 30, 2024, as compared to the six months ended June 30, 2023, primarily due to the increase in mineral reserves and the extension of the life of the mine in July 2023, partly offset by the additional depreciation charges relating to the fluorine leaching plant, which was commissioned in July 2023.

Exploration expense

Exploration expense for the six months ended June 30, 2024, was $1.9 million higher as compared to the six months ended June 30, 2023, primarily due to increased greenfields exploration.

Other expense (income)

Other expense was $2.2 million for the six months ended June 30, 2024, compared to other income of $0.9 million for the six months ended June 30, 2023. The change is primarily due to a $1.0 million loss on foreign exchange incurred for the six months ended June 30, 2024, due to the strengthening of the Mexican peso, compared to a foreign exchange gain of $1.1 million in the same period in 2023, as well as a $1.0 million positive adjustment on VAT receivable balances during the six months ended June 30, 2024.

Income tax expense

Income tax expense of $17.3 million was recorded for the six months ended June 30, 2024, compared to income tax expense of $10.7 million for the six months ended June 30, 2023. The 62% increase in income tax expense was primarily due to higher taxable income for the six months ended June 30, 2024.

Net income and comprehensive income

For the six months ended June 30, 2024, the LGJV had net income and comprehensive income of $30.7 million compared to $13.4 million for the six months ended June 30, 2023. The increase in net income and comprehensive income was primarily due to an increase in revenue and a decrease in depreciation, depletion and amortization expense, partly offset by higher cost of sales, royalties and duties, exploration, income tax expense and other expense for the six months ended June 30, 2024, compared to other income in the same period of 2023.

Sustaining capital

For the six months ended June 30, 2024, sustaining capital expenditures primarily consisted of $12.7 million of mine development and $7.6 million of infrastructure and equipment including $3.3 million for the overhaul of mining equipment. During the six months ended June 30, 2023, sustaining capital expenditures primarily consisted of $11.2 million of mine development, and $9.5 million of infrastructure and equipment including construction of the fluorine leach plant.

Table of Contents

Resource development drilling expenditures

For the six months ended June 30, 2024 and 2023, resource development drilling expenditures primarily related to resource expansion drilling of the South-East Deeps zone at CLG. The decrease of $1.9 million is primarily due to the shift from resource development drilling to greenfields exploration.

The LGJV cash and cash equivalents at June 30, 2024, increased to $45.5 million, from $34.3 million at December 31, 2023.

Cash provided by operating activities was $91.8 million and $74.4 million for the six months ended June 30, 2024 and 2023, respectively. The $17.4 million increase in cash provided by operating activities was primarily due to the increase in revenues, partly

offset by increases in cost of sales, royalties and duties and exploration for the six months ended June 30, 2024, compared to the prior year period.

Cash used by investing activities was $25.6 million and $26.0 million for the six months ended June 30, 2024 and 2023, respectively. During the six months ended June 30, 2024, $4.5 million was incurred on property, plant and equipment expenditures and $21.1 million on mine development expenditures, of which $5.1 million was associated with capitalized development drilling. During the six months ended June 30 2023, $8.7 million was incurred on property, plant and equipment expenditures, $18.6 million on mine development expenditures, of which $7.0 million was associated with capitalized development drilling, offset by $1.3 million of a cash inflow from materials and supplies inventory.

Free cash flow1 for the six months ended June 30, 2024, was $66.3 million, compared to $48.4 million in the same period in 2023 primarily due to higher cash flow provided by operating activities and a slight decrease in capital expenditures for the six months ended June 30, 2024.

Cash used by financing activities was $55.0 million and $0.5 million for the six months ended June 30, 2024 and 2023, respectively. The increase in cash used by financing activities was due to $55.0 million of capital distribution made to the LGJV partners during the six months ended June 30, 2024.

Liquidity and Capital Resources

As of June 30, 2024, and December 31, 2023, the Company had cash and cash equivalents of $82.5 million and $55.5 million, respectively. The increase in cash and cash equivalents of $27.0 million was primarily due to capital distributions of $38.5 million received from the LGJV, partly offset by general and administrative expenses.

The Company manages liquidity risk through its capital structure and the Credit Facility. At June 30, 2024, the Company's borrowing capacity on the Credit Facility is $50.0 million with an accordion feature providing up to an additional $50.0 million, subject to certain conditions. We continue to remain compliant with covenants and do not currently anticipate any events or circumstances that would impact our ability to access funds available on the Credit Facility.

On July 31, 2024, the Company’s cash and cash equivalents were $108.9 million after receipt of a capital distribution of $28.0 million from the LGJV on July 29, 2024. The LGJV had cash and cash equivalents of $24.4 million on July 31, 2024, after the capital distribution of $40.0 million to its partners on July 29, 2024. Neither the Company nor the LGJV had any debt as of June 30, 2024. We believe the Company has sufficient cash and access to borrowings and other resources to carry out its business plans for the next 12 months and beyond.

Contractual Obligations

There have been no material changes from the contractual obligations described in the 2023 10-K.

Critical Accounting Policies and Estimates

There have been no material changes to our critical accounting policies and estimates described in the 2023 10-K.

Please refer to Note 2 Summary of Significant Accounting Policies in our condensed consolidated financial statements included in this Report and the 2023 10-K for discussion of our critical accounting policies and estimates.

Jumpstart Our Business Startups Act of 2012

The Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) permits us, as an “emerging growth company,” to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for public companies that are not emerging growth companies. The decision to opt out of the extended transition period under the JOBS Act is irrevocable.

Non-GAAP Financial Measures

We use certain measures that are not defined by GAAP to evaluate various aspects of our business. These non-GAAP financial measures 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.

Table of Contents

Cash Costs and All-In Sustaining Costs

Cash costs and all-in sustaining costs (“AISC”) are non-GAAP measures. AISC was calculated based on guidance provided by the World Gold Council (“the WGC”). The WGC is not a regulatory industry organization and does not have the authority to develop accounting standards for disclosure requirements. Other mining companies may calculate AISC differently as a result of differences in underlying accounting principles and policies applied, as well as definitional differences of sustaining versus expansionary (i.e., non-sustaining) capital expenditures based upon each company’s internal policies. Current GAAP measures used in the mining industry, such as cost of sales, do not capture all of the expenditures incurred to discover, develop and sustain production. Therefore, we believe that cash costs and AISC are non-GAAP measures that provide additional information to management, investors and analysts that aid in the understanding of the economics of the Company’s operations and performance compared to other producers and provides investors visibility by better defining the total costs associated with production.

Cash costs include all direct and indirect operating cash costs related directly to the physical activities of producing metals, including mining, processing and other plant costs, treatment and refining costs, general and administrative costs, royalties and duties and mining production taxes. AISC includes total production cash costs incurred at the LGJV’s mining operations plus sustaining capital expenditures. The Company believes this measure represents the total sustainable costs of producing silver from current operations and provides additional information of the LGJV’s operational performance and ability to generate cash flows. As the measure seeks to reflect the full cost of silver production from current operations, new project and expansionary capital at current operations are not included. Certain cash expenditures such as new project spending, tax payments, dividends, and financing costs are not included.

Reconciliation of expenses (GAAP) to non-GAAP measures (Cash Costs and All-In Sustaining Costs)

The table below presents a reconciliation between the most comparable GAAP measure of the LGJV’s expenses to the non-GAAP measures of (i) cash costs, (ii) cash costs, net of by-product credits, (iii) co-product AISC and (iv) by-product AISC for our operations.

EBITDA

Management uses EBITDA to evaluate the Company’s operating performance, to plan and forecast its operations, and assess leverage levels and liquidity measures. EBITDA is defined as net income adjusted for interest expense, interest income, income tax expense and depreciation, depletion and amortization expense. The Company believes the use of EBITDA reflects the underlying operating performance of our core mining business and allows investors and analysts to compare results of the Company to similar results of other mining companies. EBITDA does not represent, and should not be considered an alternative to, net income (loss) or cash flow from operations as determined under GAAP. The table below reconciles the Company's EBITDA, a non-GAAP measure to the Company's net income (loss) and comprehensive income (loss):

EBITDA for the three and six months ended June 30, 2023, as previously reported, was not adjusted for interest income of $0.1 million and $0.3 million, respectively, as these amounts were not material for the purposes of calculating EBITDA.

The table below reconciles LGJV's EBITDA, a non-GAAP measure, to the its net income and comprehensive income:

EBITDA for the three and six month periods ended June 30, 2023, as previously reported, was not adjusted for interest income of $0.6 million and $0.6 million, respectively, as these amounts were not material for the purposes of calculating EBITDA.

Free Cash Flow

Management uses free cash flow as a non-GAAP measure to analyze cash flows generated from operations. Free cash flow is cash provided by (used in) operating activities less cash flow (used in) from investing activities as presented on the Condensed Consolidated Statements of Cash Flows. The Company believes free cash flow is also useful for investors 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 following table sets forth a reconciliation of free cash flow, a non-GAAP financial measure, to net cash provided (used) by operating activities, which the Company believes to be the GAAP financial measure most directly comparable to free cash flow.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are a "smaller reporting company" as defined under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and are not required to provide disclosure pursuant to this Item.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We have established disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our principal executive and principal financial officers as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2024. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were not effective as of June 30, 2024, due to the material weaknesses in our internal control over financial reporting described in the 2023 10-K.

Table of Contents

Changes in Internal Control over Financial Reporting

There have not been any changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended June 30, 2024, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, do not expect that our disclosure controls and procedures will prevent all errors and fraud. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving the desired control objectives. Further, the design of a control system must reflect resource constraints, which require management to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management’s override of the control.

The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Unless the context otherwise requires, references to “Gatos Silver” or the “Company” mean Gatos Silver, Inc. and its consolidated subsidiaries. The interim condensed consolidated financial statements are unaudited, but include all adjustments, consisting of normal recurring entries, which are necessary for a fair presentation for the dates and periods presented. Interim results are not necessarily indicative of results for a full year. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Accordingly, they do not include all financial information and disclosures required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission (“the SEC”) on February 20, 2024, as amended by Amendment No 1. on Form 10-K/A filed with the SEC on May 6, 2024 (as amended, the “2023 10-K”).

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Summary of Significant Accounting Policies The consolidated financial statements for the year ended December 31, 2023, disclose those accounting policies considered significant in determining results of operations and financial position. There have been no material changes to, or in the application of, the accounting policies previously identified and described in the 2023 10-K. Recent Accounting Pronouncements In March 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2024-02, Codification Improvements: Amendments to Remove References to the Concepts Statements. This ASU contains amendments to the Accounting Standards Codification (the "ASC") that remove references to various FASB Concepts Statements. The FASB has a standing project on its agenda to address suggestions received from stakeholders on the ASC and other incremental improvements to GAAP. This effort facilitates ASC updates for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or the structure of guidance, and other minor improvements. The resulting amendments are referred to as ASC improvements. The amendments of this update are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is still assessing the impact of this ASU, but does not expect it to have a material impact on the financial statements. In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The amendments in this ASU modify the disclosure or presentation requirements of a variety of Topics in the ASC. Certain amendments represent clarifications to or technical corrections of the current requirements. Each amendment in this ASU will only become effective if the SEC removes the related disclosure or presentation requirement from its existing regulations by June 30, 2027. The Company is still assessing the impact of the standard. There have been no other accounting pronouncements issued or adopted during the six months ended June 30, 2024, which are expected to have a material impact on the financial statements.

Fair Value Measurements	Jun. 30, 2024
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company establishes a framework for measuring the fair value of assets and liabilities in the form of a fair value hierarchy that prioritizes the inputs into valuation techniques used to measure fair value into three broad levels. This hierarchy gives the highest priority to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs. Further, financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement. The three levels of the fair value hierarchy are as follows: Level 1: Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date. Level 2: Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data. Level 3: Unobservable inputs due to the fact there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability. Assets and Liabilities that are Measured at Fair Value on a Non-recurring Basis The Company discloses and recognizes its non-financial assets and liabilities at fair value on a non-recurring basis and makes adjustments to fair value, as needed (for example, when there is evidence of impairment). The Company recorded its initial investment in affiliates at fair value within Level 3 of the fair value hierarchy, as the valuation was determined based on internally developed assumptions with few observable inputs and no market activity.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	Commitments, Contingencies and Guarantees In determining its accruals and disclosures with respect to loss contingencies, the Company will charge to income an estimated loss if information available prior to the issuance of the condensed consolidated financial statements indicates that it is probable that a liability has been incurred at the date of the condensed consolidated financial statements and the amount of the loss can be reasonably estimated. Legal expenses associated with the commitments and contingencies are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the condensed consolidated financial statements when it is at least reasonably possible that a material loss could be incurred. Environmental Contingencies The Company’s mining and exploration activities are subject to various laws, regulations and permits governing the protection of the environment. These laws, regulations and permits are continually changing and are generally becoming more restrictive. The Company has made, and expects to make in the future, expenditures to comply with such laws, regulations and permits, but cannot predict the full amount of such future expenditures. Legal On February 22, 2022, a purported Company stockholder filed a putative class action lawsuit in the United States District Court for the District of Colorado (the "District Court") against the Company, certain of our former officers, and several directors (the "U.S. Class Action"). An amended complaint was filed on August 15, 2022. The amended complaint, allegedly brought on behalf of certain purchasers of the Company’s common stock and certain traders of call and put options on the Company’s common stock from December 9, 2020 through January 25, 2022, seeks, among other things, damages, costs, and expenses, and asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 as well as Sections 11 and 15 of the Securities Act of 1933. The amended complaint alleges that certain individual defendants and the Company, pursuant to the control and authority of the individual defendants, made false and misleading statements and/or omitted certain material information regarding the mineral resources and reserves at the Cerro Los Gatos mine. The Company and all defendants filed a motion to dismiss this action on October 14, 2022. That motion was fully briefed as of December 23, 2022. On April 26, 2023, following a joint motion, the District Court postponed its ruling on the defendants’ motion to dismiss until on or after June 16, 2023. On June 13, 2023, the Company entered into an agreement in principle to settle the U.S. Class Action. Subject to certain conditions, including class certification by the District Court, the execution of a definitive stipulation of settlement and approval of the settlement by the District Court, the settling parties agreed to resolve the U.S. Class Action for an aggregate payment by the Company and its insurers of $21,000 to a settlement fund. On June 16, 2023, the parties filed a joint status report requesting that the District Court grant a temporary stay of all proceedings in the case pending submission of proposed settlement documentation on or before July 13, 2023. On July 13, 2023, the plaintiffs filed an unopposed motion for an order preliminarily approving a stipulation of settlement agreed by the parties and providing for class notice which will provide for (i) preliminary approval of the settlement; (ii) approval of the form and manner of giving notice of the settlement to the settlement class; and (iii) a hearing date and time to consider final and approval of the settlement and related matters (the “Preliminary Order”). On September 12, 2023, the plaintiffs filed an unopposed motion to amend the Preliminary Order to reflect certain changes to the form of release proposed to be executed by the plaintiffs. The District Court issued its Preliminary Order on February 29, 2024, approving the proposed settlement. Consistent with the stipulation of settlement requiring that a settlement account be funded within 30 days of the Preliminary Order, the Company and its insurers have fully funded that account, with $1,403 funded by the Company and $19,597 funded by the Company’s insurers. The final fairness hearing with the District Court was held on May 29, 2024. The final settlement remains subject to final court approval, and as a result, there can be no assurance that the U.S. Class Action will be resolved pursuant to the terms of the settlement agreement. By Notice of Action issued February 9, 2022, and subsequent Statement of Claim dated March 11, 2022, Izabela Przybylska (the "Plaintiff") commenced a putative class action against the Company, certain of its former officers, and others in the Ontario Superior Court of Justice on behalf of a purported class of all persons or entities, wherever they may reside or be domiciled, who acquired securities of the Company in both the primary and secondary markets during the period from October 28, 2020 until January 25, 2022 (the “Canadian Class Action”). The action asserts claims under Canadian securities legislation and at common law and seeks unspecified monetary damages and other relief in respect of allegations the defendants made false and misleading statements and omitted material information regarding the mineral resources and reserves of the Company. On January 26, 2024, counsel for the Company and counsel for the Plaintiff executed a term sheet wherein any claims against the Company and the named individuals would be settled for a payment by the Company of $3,000. Such counsel subsequently agreed to and executed a definitive settlement agreement. On April 16, 2024, the Ontario Superior Court approved the settlement on a preliminary basis. Consistent with the terms of the settlement requiring that an escrow account be funded within 30 days of preliminary court approval, the Company and its insurers have fully funded an escrow account, with $2,597 funded by the Company and $403 funded by the Company’s insurers. The final fairness hearing with the Ontario Superior Court was held on June 28, 2024, and the Ontario Superior Court issued orders approving the settlement. The Company has made disclosures to the U.S. Department of Justice (the "DOJ") and the SEC regarding its January 25, 2022 press release and issues related to CLG’s mineral reserves and mineral resources at the time. The Company has been cooperating with those agencies’ investigations. The Company was advised on July 15, 2024, that the DOJ has closed its investigation in relation to the Company. The Company understands that the SEC's investigation has not been completed and cannot reasonably predict any outcome. There can be no assurance that any of the foregoing matters individually or in aggregate will not result in outcomes that are materially adverse for the Company.

Summary of Significant Accounting Policies (Policies)	Jun. 30, 2024
Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2024-02, Codification Improvements: Amendments to Remove References to the Concepts Statements. This ASU contains amendments to the Accounting Standards Codification (the "ASC") that remove references to various FASB Concepts Statements. The FASB has a standing project on its agenda to address suggestions received from stakeholders on the ASC and other incremental improvements to GAAP. This effort facilitates ASC updates for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or the structure of guidance, and other minor improvements. The resulting amendments are referred to as ASC improvements. The amendments of this update are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is still assessing the impact of this ASU, but does not expect it to have a material impact on the financial statements. In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. The amendments in this ASU modify the disclosure or presentation requirements of a variety of Topics in the ASC. Certain amendments represent clarifications to or technical corrections of the current requirements. Each amendment in this ASU will only become effective if the SEC removes the related disclosure or presentation requirement from its existing regulations by June 30, 2027. The Company is still assessing the impact of the standard. There have been no other accounting pronouncements issued or adopted during the six months ended June 30, 2024, which are expected to have a material impact on the financial statements.
Fair Value Measurements	The Company establishes a framework for measuring the fair value of assets and liabilities in the form of a fair value hierarchy that prioritizes the inputs into valuation techniques used to measure fair value into three broad levels. This hierarchy gives the highest priority to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs. Further, financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement. The three levels of the fair value hierarchy are as follows: Level 1: Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date. Level 2: Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data. Level 3: Unobservable inputs due to the fact there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability. Assets and Liabilities that are Measured at Fair Value on a Non-recurring Basis The Company discloses and recognizes its non-financial assets and liabilities at fair value on a non-recurring basis and makes adjustments to fair value, as needed (for example, when there is evidence of impairment). The Company recorded its initial investment in affiliates at fair value within Level 3 of the fair value hierarchy, as the valuation was determined based on internally developed assumptions with few observable inputs and no market activity.
