HECLA MINING CODE

Note 1. Basis of Preparation of Financial Statements

The accompanying unaudited interim condensed consolidated financial statements of Hecla Mining Company and its subsidiaries (collectively, “Hecla,” “the Company,” “we,” “our,” or “us,” except where the context requires otherwise) have been prepared in accordance with the instructions to Form 10-Q and do not include all information and disclosures required annually by accounting principles generally accepted in the United States of America (“GAAP”). Therefore, this information should be read in conjunction with the Company’s consolidated financial statements and notes contained in our annual report on Form 10-K for the year ended December 31, 2023 (“2023 Form 10-K”). The consolidated December 31, 2023 balance sheet data was derived from our audited consolidated financial statements. The information furnished herein reflects all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods reported. All such adjustments are, in the opinion of management, of a normal recurring nature. Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024.

Note 2. Business Segments and Sales of Products

We discover, acquire and develop mines and other mineral interests and produce and market (i) concentrates containing silver, gold, lead and zinc, (ii) carbon material containing silver and gold, and (iii) doré containing silver and gold. We are currently organized and managed infour segments: Greens Creek, Lucky Friday, Keno Hill and Casa Berardi.

Effective January 2024 we revised our internal reporting provided to our Chief Operating Decision Maker to no longer include any financial performance information for our Nevada Operations, reflecting the current status of the Nevada Operations being on care and maintenance. General corporate activities not associated with operating mines and their various exploration activities, as well as idle properties and environmental remediation services in the Yukon, Canada, and the previously separately reported Nevada Operations are presented as “Other.” The presentation of the prior period information disclosed below has been revised to reflect this change.

The following tables present information about our reportable segments sales for thethree months ended March 31, 2024 and 2023 (in thousands):

Other sales for the three months ended March 31, 2024 and 2023 is comprised of revenue from our environmental remediation services subsidiary in the Yukon for both periods presented and Nevada Operations metal sales in the prior period.

Lucky Friday's income from operations for the three months ended March 31, 2024, includes $17.4 million of business interruption insurance proceeds received during the quarter related to the fire which suspended Lucky Friday's operations from August 2023 through January 8, 2024.

Total sales to external customers for thethree months ended March 31, 2024 and 2023 were as follows (in thousands):

Sales of metals for the three months ended March 31, 2024 and 2023 include net gains of $3.1 million and$0.9 million, respectively, on financially-settled forward contracts for silver, gold, lead and zinc. See Note 8 for more information.

The following table presents total assets by reportable segment as of March 31, 2024 and December 31, 2023 (in thousands):

Note 3. Income and Mining Taxes

Major components of our income and mining tax (provision) benefit for thethree months ended March 31, 2024 and 2023 are as follows (in thousands):

The income and mining tax provision for the three months ended March 31, 2024 and 2023 varies from the amounts that would have resulted from applying the statutory tax rates to pre-tax loss due primarily to the impact of taxation in foreign jurisdictions, non-recognition of net operating losses and foreign exchange gains and losses in certain jurisdictions.

For the three months ended March 31, 2024, we used the annual effective tax rate method to calculate the tax provision. Valuation allowances on Nevada, Mexico and certain Canadian net operating losses were treated as discrete adjustments to the tax provision.

Note 4. Employee Benefit Plans

We sponsor three defined benefit pension plans, two of which cover substantially all U.S. employees. Net periodic pension (benefit) cost for the plans consisted of the following for thethree months ended March 31, 2024 and 2023 (in thousands):

For the three months ended March 31, 2024 and 2023, the service cost component of net periodic pension cost is included in the same line items of our condensed consolidated financial statements as other employee compensation costs. The net benefit related to all other components of net periodic pension cost of$1.0 million for each of the three months ended March 31, 2024, and 2023, is included in other income on our condensed consolidated statements of operations and comprehensive loss.

Note 5. Loss Per Common Share

We calculate basic loss per common share on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted income per share is calculated using the weighted average number of shares of common stock outstanding during the period plus the effect of potential dilutive common shares during the period using the treasury stock and if-converted methods.

Potential dilutive shares of common stock include outstanding unvested restricted stock awards, deferred restricted stock units, warrants and convertible preferred stock for periods in which we have reported net income. For periods in which we report net losses, potential dilutive shares of common stock are excluded, as their conversion and exercise would be anti-dilutive.

The following table represents net loss per common share – basic and diluted (in thousands, except income (loss) per share):

For the three months ended March 31, 2024 and 2023, all outstanding unvested restricted stock units, deferred restricted stock units, warrants and convertible preferred stock were excluded from the computation of diluted loss per share, as our reported net loss would cause their conversion and exercise to have an anti-dilutive effect on the calculation of diluted loss per share.

Note 6. Stockholders’ Equity

At-The-Market Equity Distribution Agreement

Pursuant to an equity distribution agreement dated February 18, 2021, we may offer and sell up to 60 million shares of our common stock from time to time to or through sales agents. Sales of the shares, if any, will be made by means of ordinary brokers transactions or as otherwise agreed between the Company and the agents as principals. Whether or not we engage in sales from time to time may depend on a variety of factors, including our share price, our cash resources, customary black-out restrictions, and whether we have any material inside information. The agreement can be terminated by us at any time. Any sales of shares under the equity distribution agreement are registered under the Securities Act of 1933, as amended, pursuant to a shelf registration statement on Form

S-3. Under the agreement we have sold 14,753,958 shares for total proceeds of $76.7 million, net of commissions and fees of $1.2 million from September 2022 through March 31, 2024. During the three months ended March 31, 2024, we sold 248,561 shares under the agreement for proceeds of $1.1 million, net of commissions and fees of $0.04 million.

Stock-based Compensation Plans

The Company has stock incentive plans for executives, directors and eligible employees, comprised of performance shares and restricted stock. Stock-based compensation expense for restricted stock unit and performance-based grants (collectively "incentive compensation") to employees totaled $1.2 million for the three months ended March 31, 2024 and 2023, respectively. At March 31, 2024, there was $5.2 million of unrecognized stock-based compensation cost which is expected to be recognized over a weighted-average remaining vesting period of 1.3 years.

In connection with the vesting of incentive compensation, employees have in the past, at their election and when permitted by us, chosen to satisfy their minimum tax withholding obligations through net share settlement, pursuant to which the Company withholds the number of shares necessary to satisfy such withholding obligations and pays the obligations in cash. As a result, in the three months ended March 31, 2024, we withheld 277,966 shares valued at approximately $1.2 million, or approximately $4.31 per share.

Common Stock Dividends

The following table summarizes the dividends our Board of Directors have declared and we have paid during 2024 pursuant to our dividend policy:

Accumulated Other Comprehensive Income (Loss), Net

The following table lists the beginning balance, quarterly activity and ending balances, net of income and mining tax, of each component of “Accumulated other comprehensive income (loss), net” (in thousands):

Note 7. Debt, Credit Agreement and Leases

Our debt as of March 31, 2024 and December 31, 2023 consisted of our 7.25% Senior Notes due February 15, 2028 (“Senior Notes”), our Series 2020-A Senior Notes due July 9, 2025 (the “IQ Notes”) and any drawn amounts on our $150 million Credit Agreement, which is described separately below. The following tables summarize our long-term debt balances, excluding interest and borrowings under the Credit Agreement, as of March 31, 2024 and December 31, 2023 (in thousands):

The following table summarizes the scheduled annual future payments, including interest, for our Senior Notes, IQ Notes, and finance and operating leases as of March 31, 2024 (in thousands). Operating leases are included in other current and non-current liabilities on our condensed consolidated balance sheets. The amounts for the IQ Notes are stated in U.S. dollars (“USD”) based on the USD/Canadian dollar (“CAD”) exchange rate as of March 31, 2024.

Credit Agreement

On July 21, 2022, we entered into a revolving credit facility (the "Credit Agreement") with various financial institutions (the “Lenders”), Bank of Montreal and Bank of America, N.A. as letters of credit issuers, and Bank of America, N.A., as administrative agent for the Lenders and as swingline lender, to replace our prior credit agreement. The Credit Agreement is a $150 million senior secured revolving facility, with an option to be increased in an aggregate amount not to exceed $75 million. Any revolving loans under the Credit Agreement have a maturity date of July 21, 2026. Proceeds of the revolving loans under the Credit Agreement may be used for general corporate purposes. The interest rate on the outstanding loans under the Credit Agreement is based on the Company’s net leverage ratio and is calculated at (i) Term Secured Overnight Financing Rate ("SOFR") plus 2% to 3.5% or (ii) Bank of America’s Base Rate plus 1% to 2.5% with Base Rate being the highest of (i) the Bank of America prime rate, (ii) the Federal Funds rate plus.50% or (iii) Term SOFR plus 1.00%. For each amount drawn, we elect whether we draw on a one, three or six month basis or annual basis for SOFR. If we elect to draw for greater than six months, we pay interest quarterly on the outstanding amount.

We are also required to pay a commitment fee of between 0.45% to 0.78750%, depending on our net leverage ratio. Letters of credit issued under the Credit Agreement bear a fee between 2.00% and 3.50% based on our net leverage ratio, as well as a fronting fee to each issuing bank at an agreed upon rate per annum on the average daily dollar amount of our letter of credit exposure.

Hecla Mining Company and certain of our subsidiaries are the borrowers under the Credit Agreement, while certain of our other subsidiaries are guarantors of the borrowers’ obligations under the Credit Agreement. As further security, the Credit Agreement is collateralized by a mortgage on the Greens Creek mine, the equity interests of subsidiaries that own the Greens Creek mine or are part of the Greens Creek Joint Venture and our subsidiary Hecla Admiralty Company (the “Greens Creek Group”), and by all of the Greens Creek Group’s rights and interests in the Greens Creek Joint Venture Agreement, and in all assets of the joint venture and of any member of the Greens Creek Group.

At March 31, 2024, we had net draws of$140.0 million outstanding at an interest rate of 8.0%, and$6.8 million of outstanding letters of credit. Letters of credit that are outstanding reduce availability under the Credit Agreement.

We believe we were in compliance with all covenants under the Credit Agreement as of March 31, 2024.

See Note 13: for updates regarding the Credit Agreement.

Note 8. Derivative Instruments

General

Our current risk management policy provides that up to 75% offive years of our foreign currency, lead and zinc metals price and silver and gold price exposure may be covered under a derivatives program with certain other limitations. Our program also utilizes derivatives to manage price risk exposure created from when revenue is recognized from a shipment of concentrate until final settlement.

These instruments expose us to (i) credit risk in the form of non-performance by counterparties for contracts in which the contract price exceeds the spot price of the hedged commodity or foreign currency and (ii) price risk to the extent that the spot price or currency exchange rate exceeds the contract price for quantities of our production and/or forecasted costs covered under contract positions.

Foreign Currency

Our wholly-owned subsidiaries owning the Casa Berardi operation and Keno Hill operation are USD-functional entities which routinely incur expenses denominated in CAD. Such expenses expose us to exchange rate fluctuations between the USD and CAD. We have a program to manage our exposure to fluctuations in the USD exchange rate for these subsidiaries' future operating and capital costs denominated in CAD. The program related to forecasted cash operating costs at Casa Berardi and Keno Hill utilizes forward contracts to buy CAD, some of which are designated as cash flow hedges. As of March 31, 2024, we have a total of 493 forward contracts outstanding to buy a total of CAD $370.6 million having a notional amount of USD$278.6 million for Casa Berardi, Keno Hill, and some corporate Canadian expenses. The CAD contracts related to forecasted cash operating costs at Casa Berardi and Keno Hill from 2024-2026 have a total notional value of CAD$299.7 million and have CAD-to-USD exchange rates ranging between 1.278 and 1.3665 The CAD contracts related to forecasted capital expenditures at Casa Berardi from 2024-2026 have a total notional value of CAD$35.1 million at an average CAD-to-USD exchange rate of 1.351. The CAD contracts related to forecasted capital expenditures at Keno Hill from 2024-2026 have a total notional value of CAD$19.2 million at an average CAD-to-USD exchange rate of 1.354.

As of March 31, 2024 and December 31, 2023, we recorded the following balances for the fair value of the foreign currency forward contracts (in millions):

Net unrealized losses of $3.9 million related to the effective portion of the foreign currency forward contracts designated as hedges are included in accumulated other comprehensive income (loss) as of March 31, 2024. Unrealized gains and losses will be transferred from accumulated other comprehensive income (loss) to current earnings as the underlying operating expenses are recognized. We estimate $2.9 million in net unrealized losses included in accumulated other comprehensive income (loss) as of March 31, 2024 will be reclassified to current earnings in the next twelve months. Net realized losses of $0.4 million and $0.9 million on contracts related to underlying expenses which have been recognized were transferred from accumulated other comprehensive income (loss) and included in cost of sales and other direct production costs for thethree months ended March 31, 2024 and 2023, respectively. Net losses of $1.9 million and net gains of $0.7 million for thethree months ended March 31, 2024 and 2023, respectively, were related to contracts not designated as hedges. No net unrealized gains or losses related to ineffectiveness of the hedges are included in fair value adjustments, net on our consolidated statements of operations and comprehensive loss for thethree months ended March 31, 2024 and 2023, respectively.

Metals Prices

We are currently using financially-settled forward contracts to manage the exposure to:

•

changes in prices of silver, gold, zinc and lead contained in our concentrate shipments between the time of shipment and final settlement; and

•

changes in prices of zinc and lead (but not silver and gold) contained in our forecasted future concentrate shipments.

The following tables summarize the quantities of metals committed under forward metals contracts at March 31, 2024 and December 31, 2023:

We recorded the following balances for the fair value of the forward metals contracts as of March 31, 2024 and December 31, 2023 (in millions):

Net realized and unrealized gains of $12.5 million related to the effective portion of the forward metals contracts designated as hedges were included in accumulated other comprehensive income (loss) as of March 31, 2024. Unrealized gains and losses will be transferred from accumulated other comprehensive income (loss) to current earnings as the underlying forecasted sales are recognized. We estimate $11.2 million in net realized and unrealized gains included in accumulated other comprehensive income (loss) as of March 31, 2024 would be reclassified to current earnings in the next twelve months. The realized gains arose due to cash settlement of zinc contracts prior to maturity in 2022 and zinc and lead contracts during 2023 for net proceeds of $17.4 million and $8.5 million, respectively. We recognized a net gain of $3.1 million, including a $1.9 million gain transferred from accumulated other comprehensive income (loss), and a net gain of $0.9 million, including a $3.0 million loss transferred from accumulated other comprehensive income(loss) during thethree months ended March 31, 2024 and 2023, respectively. These gains and losses were recognized on the contracts utilized to manage exposure to prices of metals in our concentrate shipments, which are included in sales. The net losses and gains recognized on the contracts offset gains and losses related to price adjustments on our provisional concentrate sales due to changes to silver, gold, lead and zinc prices between the time of sale and final settlement.

Credit-risk-related Contingent Features

Certain of our derivative contracts contain cross default provisions which provide that a default under our Credit Agreement would cause a default under the derivative contract. As of March 31, 2024, we have not posted any collateral related to these contracts. The fair value of derivatives in a net liability position related to these agreements was $5.4 million as of March 31, 2024, which includes accrued interest but excludes any adjustment for nonperformance risk. If we were in breach of any of these provisions at March 31, 2024, we could have been required to settle our obligations under the agreements at their termination value of $5.4 million.

Note 9. Fair Value Measurement

Fair value adjustments, net is comprised of the following (in thousands):

Accounting guidance has established a hierarchy for inputs used to measure assets and liabilities at fair value on a recurring basis. The three levels included in the hierarchy are:

Level 1: quoted prices in active markets for identical assets or liabilities;

Level 2: significant other observable inputs; and

Level 3: significant unobservable inputs.

The table below sets forth our assets and liabilities that were accounted for at fair value on a recurring basis and the fair value calculation input hierarchy level that we have determined applies to each asset and liability category (in thousands).

Cash and cash equivalents consist primarily of money market funds and are valued at cost, which approximates fair value.

Current and non-current restricted cash and cash equivalent balances consist primarily of certificates of deposit, U.S. Treasury securities, and other deposits and are valued at cost, which approximates fair value.

Our non-current investments consist of marketable equity securities of companies in the mining industry which are valued using quoted market prices for each security.

Trade accounts receivable from provisional concentrate sales are subject to final pricing and valued using quoted prices based on forward curves for the particular metals.

We use financially-settled forward contracts to manage exposure to changes in the exchange rate between USD and CAD, and the impact on CAD-denominated operating and capital costs incurred at our Casa Berardi operation and the Keno Hill operation (see Note 8 for more information). The fair value of each contract represents the present value of the difference between the forward exchange rate for the contract settlement period as of the measurement date and the contract settlement exchange rate.

We use financially-settled forward contracts to manage the exposure to changes in prices of silver, gold, zinc and lead contained in our concentrate shipments that have not reached final settlement. We also use financially-settled forward contracts to manage the exposure to changes in prices of silver, gold, zinc and lead contained in our forecasted future sales (see Note 8 for more information). The fair value of each forward contract represents the present value of the difference between the forward metal price for the contract settlement period as of the measurement date and the contract settlement metal price.

At March 31, 2024, our Senior Notes and IQ Notes were recorded at their carrying value of $471.5 million and $35.8 million, respectively, net of unamortized initial purchaser discount/premium and issuance costs. The estimated fair values of our Senior Notes and IQ Notes were $477.6 million and $35.9 million, respectively, at March 31, 2024. Quoted market prices, which we consider to be

Level 1 inputs, are utilized to estimate fair values of the Senior Notes. Unobservable inputs which we consider to be Level 3, including an assumed current annual yield of 8.06%, are utilized to estimate the fair value of the IQ Notes. See Note 7 for more information. The Credit Agreement, which we consider to be Level 1 in the fair value hierarchy, has a carrying and fair value of $140 million.

Note 10. Product Inventories

Our major components of product inventories are (in thousands):

Note 11. Commitments, Contingencies and Obligations

Johnny M Mine Area near San Mateo, McKinley County and San Mateo Creek Basin, New Mexico

In August 2012, Hecla Limited and the U.S. Environmental Protection Agency (the “EPA”) entered into a Settlement Agreement and Administrative Order on Consent for Removal Action (“Consent Order”) regarding the Johnny M Mine Area near San Mateo, McKinley County, New Mexico. Mining at the Johnny M Mine was conducted for a limited period of time by a predecessor of Hecla Limited, and the EPA had previously asserted that Hecla Limited may be responsible under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) for environmental remediation and past costs incurred by the EPA at the site. Under the Consent Order, Hecla Limited agreed to pay (i) $1.1 million to the EPA for its past response costs at the site and (ii) any future response costs at the site under the Consent Order, in exchange for a covenant not to sue by the EPA. In December 2014, Hecla Limited submitted to the EPA the Engineering Evaluation and Cost Analysis (“EE/CA”) for the site which recommended on-site disposal of mine-related material. In January 2021, the parties began negotiating a new consent order to design and implement the on-site disposal response action recommended in the EE/CA. Based on the foregoing, we believe it is probable that Hecla Limited will incur a liability for the CERCLA removal action and we have accrued $10.1 million, primarily representing estimated current costs to design and implement the remedy, which are subject to change as fieldwork is performed. It is possible that Hecla Limited’s liability will be more than $10.1 million, and any increase in liability could have a material adverse effect on Hecla Limited’s or our results of operations or financial position.

The Johnny M Mine is in an area known as the San Mateo Creek Basin (“SMCB”), which is an approximately 321 square mile area in New Mexico that contains numerous legacy uranium mines and mills. In addition to Johnny M, Hecla Limited’s predecessor was involved at other mining sites within the SMCB. The EPA appears to have deferred consideration of listing the SMCB site on CERCLA’s National Priorities List (“Superfund”) by removing the site from its emphasis list, and is working with various potentially responsible parties (“PRPs”) at the site in order to study and potentially address perceived groundwater issues within the SMCB. The EE/CA discussed above relates primarily to contaminated rock and soil at the Johnny M site, not groundwater and not elsewhere within the SMCB site. It is possible that Hecla Limited’s liability at the Johnny M Site, and for any other mine site within the SMCB at which Hecla Limited’s predecessor may have operated, will be greater than our current accrual of $10.1 million due to the increased scope of required remediation.

In July 2018, the EPA informed Hecla Limited that it and several other PRPs may be liable for cleanup of the SMCB site or for costs incurred by the EPA in cleaning up the site. The EPA stated it has incurred approximately $9.6 million in response costs to date. On May 2, 2022, Hecla Limited received a letter from a PRP notifying Hecla Limited that three PRPs will seek cost recovery and contribution from Hecla Limited under CERCLA for certain investigatory work performed by the PRPs at the SMCB site. Hecla Limited cannot with reasonable certainty estimate the amount or range of liability, if any, relating to this matter because of, among other reasons, the lack of information concerning the site, including the relative contributions of contamination by the various PRPs.

Carpenter Snow Creek and Barker-Hughesville Sites in Montana

In July 2010, the EPA made a formal request to Hecla for information regarding the Carpenter Snow Creek Superfund site located in Cascade County, Montana. The Carpenter Snow Creek site is located in a historical mining district, and in the early 1980s Hecla Limited leased 6 mining claims and performed limited exploration activities at the site. Hecla Limited terminated the mining lease in 1988.

In June 2011, the EPA informed Hecla Limited that it believes Hecla Limited, and several other PRPs, may be liable for cleanup of the site or for costs incurred by the EPA in cleaning up the site. The EPA stated in the letter that it has incurred approximately $4.5 million in response costs and estimated that total remediation costs may exceed $100 million. Hecla Limited cannot with reasonable certainty estimate the amount or range of liability, if any, relating to this matter because of, among other reasons, the lack of information concerning the site, including the relative contributions of contamination by various other PRPs.

In February 2017, the EPA made a formal request to Hecla for information regarding the Barker-Hughesville Mining District Superfund site located in Judith Basin and Cascade Counties, Montana. Hecla Limited submitted a response in April 2017. The Barker-Hughesville site is located in a historic mining district, and between approximately June and December 1983, Hecla Limited was party to an agreement with another mining company under which limited exploration activities occurred at or near the site.

In August 2018, the EPA informed Hecla Limited that it and several other PRPs may be liable for cleanup of the site or for costs incurred by the EPA in cleaning up the site. The EPA did not include an amount of its alleged response costs to date. Hecla Limited cannot with reasonable certainty estimate the amount or range of liability, if any, relating to this matter because of, among other reasons, the lack of information concerning past or anticipated future costs at the site and the relative contributions of contamination by various other PRPs.

Lucky Friday and Keno Hill Environmental Issues

On July 12, 2022, our Lucky Friday mine received a notice of violation from the EPA alleging violations of the Clean Water Act between 2018 and 2021 relating primarily to concentration levels of zinc and lead in the mine’s permitted water discharges. Currently, the EPA has not initiated any formal enforcement proceeding against our Lucky Friday subsidiary. In civil judicial cases, the EPA can seek statutory penalties up to $59,973 per day per violation and, in administrative actions, the EPA can seek administrative penalties up to $23,989 per day per violation with a maximum administrative penalty of $299,989 for all alleged violations. The EPA typically pursues administrative penalties. At this time, we cannot reasonably assess the amount of penalties the EPA may seek, or predict the terms of any potential settlement with the EPA.

On December 14, 2023 and January 29, 2024, our Keno Hill mine received notice from the Yukon government that it is charged with violating the Quartz Mining Act and the Waters Act, two statutes of the Yukon Territory, relating to alleged violations of Keno Hill’s mining license and water license. The allegations are that the mine stored hazardous materials inconsistent with the terms of its mining license on or between April 19, 2022 and July 25, 2023 and exceeded water discharge limits in its water license on June 27 and December 6, 2023. If convicted, the maximum fine for an offense under both of these laws is $100,000 per offense. Because we are at the initial stages of this regulatory proceeding, we cannot reasonably predict the outcome of this matter at this time.

Litigation Related to Klondex Acquisition

On May 24, 2019, a purported Hecla stockholder filed a putative class action lawsuit in the U.S. District Court for the Southern District of New York against Hecla and certain of our executive officers, one of whom is also a director. The complaint, purportedly brought on behalf of all purchasers of Hecla common stock from March 19, 2018 through and including May 8, 2019, asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder and seeks, among other things, damages and costs and expenses. Specifically, the complaint alleges that Hecla, under the authority and control of the individual defendants, made certain material false and misleading statements and omitted certain material information regarding Hecla’s Nevada Operations. The complaint alleges that these misstatements and omissions artificially inflated the market price of Hecla common stock during the class period, thus purportedly harming investors. The Court granted our Motion to Dismiss the lawsuit, without prejudice, in February 2023, and the plaintiffs filed an amended complaint in March 2023 which repeats the same claims. We have filed a Motion to Dismiss the amended complaint. We cannot predict the outcome of this lawsuit or estimate damages if plaintiffs were to prevail. We believe that these claims are without merit and intend to defend them vigorously.

Related to this class action lawsuit, Hecla has been named as a nominal defendant in a shareholder derivative lawsuit which also names as defendants certain current and past (i) members of Hecla’s Board of Directors and (ii) officers of Hecla. The case was filed on May 4, 2022 in the Delaware Chancery Court. In general terms, the suit alleges breaches of fiduciary duties by the individual defendants, waste of corporate assets and unjust enrichment, and seeks damages, purportedly on behalf of Hecla.

Debt

See Note 7 for information on the commitments related to our debt arrangements as of March 31, 2024.

Other Commitments

Our contractual obligations as of March 31, 2024 included open purchase orders and commitments of $11.1 million, $17.5 million, $10.2 million, $2.5 million and $0.8 million for various capital and non-capital items at Greens Creek, Lucky Friday, Keno Hill, Casa Berardi and Other, respectively. We also have total commitments of $26.4 million relating to scheduled payments on finance leases, including interest, primarily for equipment at our Greens Creek, Lucky Friday, Casa Berardi, and Keno Hill units, and total commitments of $13.5 million relating to payments on operating leases (see Note 7 for more information). As part of our ongoing business and operations, we are required to provide surety bonds, bank letters of credit, and restricted deposits for various purposes, including financial support for environmental reclamation obligations and workers compensation programs. As of March 31, 2024, we had surety bonds totaling $195.3 million and letters of credit totaling $6.8 million in place as financial support for future reclamation and closure costs, self-insurance, and employee benefit plans. The obligations associated with these instruments are generally related to performance requirements that we address through ongoing operations. As the requirements are met, the beneficiary of the associated instruments cancels or returns the instrument to the issuing entity. Certain of these instruments are associated with operating sites with long-lived assets and will remain outstanding until closure of the sites. We believe we are in compliance with all applicable bonding requirements and will be able to satisfy future bonding requirements as they arise.

Other Contingencies

We also have certain other contingencies resulting from litigation, claims, EPA investigations, and other commitments and are subject to a variety of environmental and safety laws and regulations incident to the ordinary course of business. We currently have no basis to conclude that any or all of such contingencies will materially affect our financial position, results of operations or cash flows. However, in the future, there may be changes to these contingencies, or additional contingencies may occur, any of which might result in an accrual or a change in current accruals recorded by us, and there can be no assurance that their ultimate disposition will not have a material adverse effect on our financial position, results of operations or cash flows.

Note 12. Developments in Accounting Pronouncements

Accounting Standards Updates Adopted

In March 2020, ASU No. 2020-04 was issued which provides optional guidance for a limited period of time to ease the potential burden on accounting for contract modifications caused by reference rate reform. In January 2021, ASU No. 2021-01 was issued which broadened the scope of ASU No. 2020-04 to include certain derivative instruments. In December 2022, ASU No. 2022-06 was issued which deferred the sunset date of ASU No. 2020-04. The guidance is effective for all entities as of March 12, 2020 through December 31, 2024. The guidance may be adopted over time as reference rate reform activities occur and should be applied on a prospective basis. Certain of our derivative instruments previously referenced London Interbank Offered Rate ("LIBOR") based rates and have been amended to eliminate the LIBOR-based rate references prior to July 1, 2023. There have been no significant impacts to our financial results, financial position or cash flows from the transition from LIBOR to alternative reference interest rates.

Accounting Standards Updates to Become Effective in Future Periods

In August 2023, the FASB issued ASU 2023-05, Business Combinations - Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement, which clarifies the business combination accounting for joint venture formations. The amendments in the ASU seek to reduce diversity in practice that has resulted from a lack of authoritative guidance regarding the accounting for the formation of joint ventures in separate financial statements. The amendments also seek to clarify the initial measurement of joint venture net assets, including businesses contributed to a joint venture. The guidance is applicable to all entities involved in the formation of a joint venture. The amendments are effective for all joint venture formations with a formation date on or after January 1, 2025. Early adoption and retrospective application of the amendments are permitted. We do not expect adoption of the new guidance to have a material impact on our consolidated financial statements and disclosures.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, amending reportable segment disclosure requirements to include disclosure of incremental segment information on an annual and interim basis. Among the disclosure enhancements are new disclosures regarding significant segment expenses that are regularly provided to the chief operating decision-maker and included within each reported measure of segment profit or loss, as well as other segment items bridging segment revenue to each reported measure of segment profit or loss. The amendments in ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, and are applied retrospectively. Early adoption is permitted. We continue to evaluate the impact of this update on our consolidated financial statements and disclosures and don't expect any changes to our current reportable segments.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures, amending income tax disclosure requirements for the effective tax rate reconciliation and income taxes paid. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024 and are applied prospectively. Early adoption and retrospective applicationof the amendments are permitted. We are currently evaluating the impact of this update on our consolidated financial statements and disclosures.
