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 (“SEC”) on February 20, 2024, and the amended Annual Report on Form 10-K/A filed with the SEC on May 6, 2024 (collectively 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 Securities and Exchange Commission 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 three months ended March 31, 2024, which are expected to have a material impact on the financial statements.

No stock options were exercised during the three months ended March 31, 2024 and 2023.

Total unrecognized stock-based compensation expense as of March 31, 2024, was $3,520, which is expected to be recognized over a weighted average period of 2.1 years.

Stock option activity for the three months ended March 31, 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	592,753	$	6.41
Forfeited	(17,818)	$	6.82
Expired	(9,946)	$	11.62
Outstanding at March 31, 2024	3,181,504	$	8.38
Vested at March 31, 2024	1,928,955	$	9.55

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

	January 2024
Risk-free interest rate	3.86	%
Dividend yield	—
Estimated volatility	58.00	%
Expected option life	6 years

At March 31, 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 during the three months ended March 31, 2024 and March 31, 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 March 31, 2024, there were 40,802 PSUs outstanding. On March 31, 2024, unrecognized compensation expense related to the PSUs was $115, which is expected to be recognized over a weighted-average period of 0.7 years.

7

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 of the grant date.

During the three months ended March 31, 2024, the Company granted 296,375 RSUs with grant date fair value of $6.41. During the period, 11,948 RSUs were forfeited. No RSUs were granted during the three months ended March 31, 2023.

The following table summarizes the RSU activity for the three months ended March 31, 2024:

Employee RSUs	Number of RSUs	Weighted‑ Average Price Per Share
Outstanding at December 31, 2023	925,172	$	5.04
Granted	296,375	$	6.41
Forfeited	(11,948)	$	5.50
Expired	—	$	—
Outstanding at March 31, 2024	1,209,599	$	8.38

Compensation expense is recognized ratably from the grant date over the requisite vesting period. On March 31, 2024, unrecognized compensation expense related to the RSUs was $4,511, which is expected to be recognized over a weighted-average period of 1.76 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.

During the three months ended March 31, 2024, the Company granted 909 DSUs. No DSUs were granted during the three months ended March 31, 2023.

The following table summarizes the DSU activity for the three months ended March 31, 2024:

Employee and Director DSUs	Number of DSUs	Weighted‑ Average Grant Price
Outstanding at December 31, 2023	302,920	$	7.76
Granted	909	$	8.39
Outstanding at March 31, 2024	303,829	$	7.76

7.    Net Income per Share

Basic net income per share is computed by dividing net income available to common shareholders 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 PSUs, DSUs or RSUs were converted into common stock. The dilutive effects are calculated using the treasury stock method.

For the three months ended March 31, 2024, and March 31, 2023, weighted average outstanding in-the-money stock options, PSUs, RSUs and DSUs are included in dilutive earnings per common share calculation.

A reconciliation of basic and diluted earnings per common share for the three months ended March 31, 2024 and 2023, is as follows:

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. 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 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 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 is scheduled with the District Court for May 29, 2024.

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 us 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 is scheduled with the Ontario Superior Court for June 28, 2024.

Since the settlements of the U.S. Class Action and the Canadian Class Action are subject to conditions, including final court approvals, there can be no assurance that either the U.S. Class Action or the Canadian Class Action will be finally resolved pursuant to the agreements that have been reached.

Further, the Company has made disclosures to the U.S. Department of Justice and the SEC regarding its January 25, 2022 press release and issues related to Cerro Los Gatos’ mineral reserves and mineral resources at the time. The Company is cooperating with those agencies’ investigations 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.

11.    Investment in Affiliates

During the three months ended March 31, 2024 and 2023, the Company recognized $7,288 and $5,011 of income, respectively, on its investment in the LGJV Entities, representing its ownership share of the LGJV Entities’ results, including the effect of the priority distribution payment. The equity income or loss in affiliates includes amortization of the carrying value of the investment in excess of the underlying net assets of the LGJV Entities.

Gatos Silver

Three Months Ended March 31, 2024, Compared to Three Months Ended March 31, 2023

General and administrative expenses

The $1.4 million increase in general and administrative expenses resulted primarily from a $0.9 million increase in non-cash stock-based compensation expense as a result of a January 2024 equity grant, and a $0.6 million increase in non-recurring legal defense fees.

Equity income in affiliates

The $2.3 million increase in equity income in affiliates resulted primarily from a $0.2 million reduction in the obligation under the priority distribution agreement in 2024 compared to the recognition of an obligation of $3.9 million under the priority distribution agreement in 2023, partly offset by a decrease in equity income from the LGJV of $1.8 million. The LGJV recorded net income of $10.2 million for the three months ended March 31, 2024, compared to $12.7 million for the three months ended March 31, 2023. See “Results of operations LGJV” below.

Interest income

The $0.6 million increase in interest income was due to an increase in cash balances during the period and an increase in the interest rate earned on cash deposits.

Total Revenue	$	72,218	$	69,865

Total revenue increased by 3% for the three months ended March 31, 2024, compared to the three months ended March 31, 2023, primarily as a result of a 94% increase in a provisional revenue adjustment to $0.9 million loss in the period ended March 31, 2024, from a $13.6 million loss in the same period of 2023. Provisional revenue adjustments account for commodity price fluctuations in concentrate sales still subject to final settlement. Sales volumes of payable silver, zinc, lead and gold increased 1%, 14%, 12% and 5%, respectively. The average realized prices of silver, zinc and lead decreased 14%, 25% and 19%, respectively, and the average realized gold price increased by 9%. Treatment and refining charges decreased by 5%.

Table of Contents

Cost of sales

Cost of sales increased by 18% primarily due to increasing processing costs as a result of a 12% increase in mill throughput and a 17% increase in the tonnage of the concentrate sold. Cost of sales were 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 and by-product cash cost per ounce of payable silver increased to $11.70 and $6.09, respectively, primarily due to a lower contribution from by-products due to substantially lower realized zinc and lead prices.

Royalties expense

Royalty expense decreased by $0.1 million for the three months ended March 31, 2024, due to lower revenue before provisional price adjustments.

General and administrative expenses

General and administrative expenses for the three months ended March 31, 2024, were $0.3 million higher compared to the three months ended March 31, 2023. The increase was primarily due to the increase in the management fee payable to the Company agreed to in October 2023, with an effective date of January 1, 2023.

Depreciation, depletion and amortization expense

Depreciation, depletion, and amortization expense decreased by 3% for the three months ended March 31, 2024, as compared to the three months ended March 31, 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 three months ended March 31, 2024, was $0.9 million higher as compared to the three months ended March 31, 2023, primarily due to increased green-fields exploration. During the quarter two drill holes were completed at Portigueño and the LGJV also progressed with the mapping of five prospective areas: San Luis, Lince, La Paula, San Agustin and Portigueño.

Other loss (income)

Other expense was $0.3 million for the three months ended March 31, 2024, compared to other income of $0.4 million for the three months ended March 31, 2023. The increase in other expense is primarily due to a $0.1 million loss on foreign exchange incurred for the three months ended March 31, 2024, due to the strengthening of the Mexican peso, compared to a gain of $0.8 million in the same period in 2023. The loss on foreign exchange was partly offset by interest income of $0.3 million and a decrease in accretion expense of $0.1 million.

Income tax expense

Income tax expense of $4.8 million was recorded for the three months ended March 31, 2024, compared to income tax expense of $6.0 million for the three months ended March 31, 2023. The 20% decrease in income tax expense was primarily due to lower taxable income for the three months ended March 31, 2024.

Net income and comprehensive income

For the three months ended March 31, 2024, the LGJV had net income and comprehensive income of $10.2 million compared to $12.7 million for the three months ended March 31, 2023. The decrease in net income was primarily due to increases in cost of sales, exploration, general and administrative and other expenses in 2024, compared to 2023, partly offset by higher revenues and a decrease in royalties and depreciation, depletion and amortization expenses

Sustaining capital

For the three months ended March 31, 2024, sustaining capital expenditures primarily consisted of $5.8 million for mine development and $2.5 million for infrastructure and equipment including $1.7 million for the overhaul of mining equipment. During the three months ended March 31, 2023, sustaining capital expenditures primarily consisted of $5.3 million for mine development, $2.4 million for infrastructure and equipment including construction of the fluorine leach plant.

Resource development drilling expenditures

For the three months ended March 31, 2024 and March 31, 2023, resource development drilling expenditures primarily related to resource expansion drilling of the South-East Deeps zone at CLG.

Cash Flows

Gatos Silver

The following table presents summarized information relating to the Company’s cash flows for the three months ended March 31, 2024 and 2023.

Cash and cash equivalents, beginning of period	$	55,484	$	17,004
Cash and cash equivalents, end of period	$	70,586	$	12,901

The cash and cash equivalents at March 31, 2024, increased to $70.6 million from $55.5 million at December 31, 2023.

For the three months ended March 31, 2024, cash provided by operating activities was $15.1 million operating activities, compared to $4.1 million used by operating activities in the three months ended March 31, 2023, due to the $21.0 million distribution received from the LGJV partially offset by higher general and administrative expenses.

Free cash flow1 for three months ended March 31, 2024 increased to $15.1 million from $(4.1) million for three months ended March 31, 2023, primarily due to the receipt of a capital distribution from LGJV on February 15, 2024.

LGJV

The following table presents summarized information relating to the LGJV’s cash flows for the three months ended March 31, 2024 and 2023.

	Three Months Ended March 31,
(in thousands)	2024		2023
Net cash provided (used) by
Operating activities	$	37,325	$	40,044
Investing activities	(11,828)		(11,366)
Financing activities	(30,016)		(290)
Total change in cash	$	(4,519)	$	28,388
Cash and cash equivalents, beginning of period	$	34,303	$	34,936
Cash and cash equivalents, end of period	$	29,784	$	63,324

The LGJV cash and cash equivalents at March 31, 2024 decreased to $29.8 million, from $34.3 million at December 31, 2023.

Cash provided by operating activities was $37.3 million and $40.0 million for the three months ended March 31, 2024 and 2023, respectively. The $2.7 million decrease in cash provided by operating activities was primarily due to the increase in cost of sales, and exploration and general and administrative expenses for the three months ended March 31, 2024, compared to the prior year period.

Cash used by investing activities was $11.8 million and $11.4 million for the three months ended March 31, 2024 and 2023, respectively. In the three months ended March 31, 2024, $1.8 million was incurred on property, plant and equipment expenditures and $10 million on mine development expenditures, of which $3.2 million was associated with capitalized development drilling.

The free cash flow1 for the three months ended March 31, 2024, was $25.5 million, compared to $28.7 million in the same period in 2023 primarily due to lower cash flow provided by operating activities and a slight increase in capital expenditures for the three months ended March 31, 2024.

Cash used by financing activities was $30.0 million and $0.3 million for the three months ended March 31, 2024 and 2023, respectively. The LGJV made a $30.0 million capital distribution to the LGJV partners in February 2024.

Liquidity and Capital Resources

As of March 31, 2024, and December 31, 2023, the Company had cash and cash equivalents of $70.6 million and $55.5 million, respectively. The increase in cash and cash equivalents of $15.1 million was primarily to a $21.0 million capital distribution received from the LGJV on February 15, 2024. At March 31, 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 April 30, 2024, the Company’s cash and cash equivalents were $85.4 million after receipt of a capital distribution of $17.5 million from the LGJV on April 22, 2024. The LGJV had cash and cash equivalents of $20.0 million million on April 30, 2024, after the capital distribution of $25.0 million to its partners on April 22, 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. The Company manages liquidity risk through its capital structure and the Credit Facility.

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.

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 (“WGC”). 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 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 or cash flow from operations as determined under GAAP. The table below reconciles the Company's EBITDA, a non-GAAP measure to Net Income:

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.

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 March 31, 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 March 31, 2024, due to the material weaknesses in our internal control over financial reporting described in the 2023 10-K.

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 March 31, 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

30

Table of Contents

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.

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 (“SEC”) on February 20, 2024, and the amended Annual Report on Form 10-K/A filed with the SEC on May 6, 2024 (collectively the “2023 10-K”).

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 Securities and Exchange Commission 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 three months ended March 31, 2024, which are expected to have a material impact on the financial statements.

No stock options were exercised during the three months ended March 31, 2024 and 2023.

Total unrecognized stock-based compensation expense as of March 31, 2024, was $3,520, which is expected to be recognized over a weighted average period of 2.1 years.

Stock option activity for the three months ended March 31, 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

Estimated volatility	58.00	%
Expected option life	6 years

At March 31, 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 during the three months ended March 31, 2024 and March 31, 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 March 31, 2024, there were 40,802 PSUs outstanding. On March 31, 2024, unrecognized compensation expense related to the PSUs was $115, which is expected to be recognized over a weighted-average period of 0.7 years.

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 of the grant date.

During the three months ended March 31, 2024, the Company granted 296,375 RSUs with grant date fair value of $6.41. During the period, 11,948 RSUs were forfeited. No RSUs were granted during the three months ended March 31, 2023.

Compensation expense is recognized ratably from the grant date over the requisite vesting period. On March 31, 2024, unrecognized compensation expense related to the RSUs was $4,511, which is expected to be recognized over a weighted-average period of 1.76 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.

During the three months ended March 31, 2024, the Company granted 909 DSUs. No DSUs were granted during the three months ended March 31, 2023.

Earnings Per Share [Abstract]

Net Income per Share

Net Income per Share

Basic net income per share is computed by dividing net income available to common shareholders 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 PSUs, DSUs or RSUs were converted into common stock. The dilutive effects are calculated using the treasury stock method.

For the three months ended March 31, 2024, and March 31, 2023, weighted average outstanding in-the-money stock options, PSUs, RSUs and DSUs are included in dilutive earnings per common share calculation.

A reconciliation of basic and diluted earnings per common share for the three months ended March 31, 2024 and 2023, is as follows:

Fair Value Measurements

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 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 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 is scheduled with the District Court for May 29, 2024.

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 us 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 is scheduled with the Ontario Superior Court for June 28, 2024.

Since the settlements of the U.S. Class Action and the Canadian Class Action are subject to conditions, including final court approvals, there can be no assurance that either the U.S. Class Action or the Canadian Class Action will be finally resolved pursuant to the agreements that have been reached.

Further, the Company has made disclosures to the U.S. Department of Justice and the SEC regarding its January 25, 2022 press release and issues related to Cerro Los Gatos’ mineral reserves and mineral resources at the time. The Company is cooperating with those agencies’ investigations 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.

Investment in Affiliates

During the three months ended March 31, 2024 and 2023, the Company recognized $7,288 and $5,011 of income, respectively, on its investment in the LGJV Entities, representing its ownership share of the LGJV Entities’ results, including the effect of the priority distribution payment. The equity income or loss in affiliates includes amortization of the carrying value of the investment in excess of the underlying net assets of the LGJV Entities. This basis difference is being amortized as the LGJV Entities’ proven and probable reserves are processed.

On February 15, 2024, the LGJV made a $30,000 capital distribution to the LGJV partners, of which the Company’s share was $21,000.

Subsequently, on April 22, 2024, the LGJV made a $25,000 capital distribution to the LGJV partners, of which the Company’s share was $17,500.

The LGJV Entities’ combined balance sheets as of March 31, 2024, and December 31, 2023, the combined statements of income for the three months ended March 31, 2024 and 2023, and the statement of cash flows for the three months ended March 31, 2024 and 2023 are as follows:

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 Securities and Exchange Commission 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 three months ended March 31, 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.
