Note 1. Bas is 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, 2024. The consolidated December 31, 2024 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 the fair presentation 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 and six months ended June 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025.

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, zinc and copper, (ii) carbon material containing silver and gold, and (iii) doré containing silver and gold. We are currently organized and managed in four segments: Greens Creek, Lucky Friday, Keno Hill and Casa Berardi.

The Company regularly reviews its segment reporting for alignment with its strategic goals and operational structure as well as for evaluation of business performance and the allocation of resources by Hecla's President and Chief Executive Officer, who has been identified as our Chief Operating Decision Maker ("CODM"). The CODM evaluates the performance for all of our reportable segments based on segment gross profit or loss. For all segments, the CODM uses segment gross profit or loss to assess segment performance and allocate resources for each segment predominantly in the annual budget and forecasting process. The CODM considers budget to actual variances on a monthly basis when making decisions about allocating capital and personnel to the segments. Significant segment expenses that are components of total cost of goods sold and drive the financial performance of our reportable segments are (i) salaries, wages and other benefits, (ii) contractors, (iii) consumables (iv) change in product inventory and (v) other direct production costs. In further evaluating the operational performance of each segment, the CODM also considers the amount of metals production versus budget, and the grade of the metal processed.

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, are presented as “other.” The nature of the items that reconcile gross profit to income before income and mining taxes are not related to our reportable segments.

Note 3. Income and Mining Taxes

Major components of our income and mining tax for the three and six months ended June 30, 2025 and 2024 are as follows (in thousands):

|  | Three Months Ended |  |  | Six Months Ended |
|  | June 30, |  |  | June 30, |
|  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |
Current: |  |  |  |  |  |  |  |  |  |  |  |
Domestic |  | $ | (2,713 | ) |  | $ | (1,961 | ) |  | $ | (5,328 | ) |  | $ | (2,953 | )
Foreign |  |  | (3,560 | ) |  |  | (1,275 | ) |  |  | (3,869 | ) |  |  | (2,254 | )
Total current income and mining tax provision |  |  | (6,273 | ) |  |  | (3,236 | ) |  |  | (9,197 | ) |  |  | (5,207 | )
Deferred: |  |  |  |  |  |  |  |  |  |  |  |
Domestic |  |  | (19,288 | ) |  |  | (11,440 | ) |  |  | (31,012 | ) |  |  | (16,623 | )
Foreign |  |  | (7,000 | ) |  |  | 5,596 |  |  |  | (8,497 | ) |  |  | 10,935 |
Total deferred income and mining tax provision |  |  | (26,288 | ) |  |  | (5,844 | ) |  |  | (39,509 | ) |  |  | (5,688 | )
Total income and mining tax provision |  | $ | (32,561 | ) |  | $ | (9,080 | ) |  | $ | (48,706 | ) |  | $ | (10,895 | )

The income and mining tax provision for the three and six months ended June 30, 2025 and 2024 varies from the amounts that would have resulted from applying the statutory tax rates to pre-tax income or 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 and six months ended June 30, 2025, 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.

On July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was enacted in the U.S. The OBBBA permanently extends multiple tax provisions of the 2017 Tax Cuts and Jobs Act, as well as repeals, modifies and introduces various other tax provisions. We do not anticipate the OBBBA to have a material impact to the Company's consolidated financial statements. We continue to evaluate the impact the OBBBA may have on the Company as the legislation has various future effective dates.

Note 4. Employee Benefit Plans

We sponsor defined benefit pension plans covering all non-hourly U.S. employees hired prior to July 2024 and our hourly workers at the Lucky Friday mine, as well as and a Supplemental Excess Retirement Plan covering certain eligible employees.

Net periodic pension cost (benefit) for the plans consisted of the following for the three and six months ended June 30, 2025 and 2024 (in thousands):

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

Service cost |  | $ | 1,068 |  |  | $ | 915 |  |  | $ | 2,136 |  |  | $ | 1,830 |
Interest cost |  |  | 2,094 |  |  |  | 2,075 |  |  |  | 4,188 |  |  |  | 4,151 |
Expected return on plan assets |  |  | (3,251 | ) |  |  | (3,136 | ) |  |  | (6,502 | ) |  |  | (6,272 | )
Amortization of prior service cost |  |  | 20 |  |  |  | 66 |  |  |  | 40 |  |  |  | 132 |
Amortization of net loss |  |  | 326 |  |  |  | 16 |  |  |  | 652 |  |  |  | 31 |
Net periodic pension cost (benefit) |  | $ | 257 |  |  | $ | (64 | ) |  | $ | 514 |  |  | $ | (128 | )

For the three and six months ended June 30, 2025 and 2024, the service cost component of net periodic pension benefit is included in the same line items of our condensed co nsolidated financial statements as other employee compensation costs. The net benefit related to all other components of net periodic pension cost of $0.8 million and $1.6 million, for the three and six months ended June 30, 2025, respectively, and $1.0 million and $2.0 million, respectively, for the three and six months ended June 30, 2024, is included in other income on our condensed consolidated statements of operations and comprehensive income.

Note 5. Earnings Per Common Share

We calculate basic earnings per common share on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted earnings 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, unvested performance based units and convertible preferred stock (collectively referred to as dilutive units) for all periods in which we have reported net income. The 2025 dilutive units exclude the impact of 2,068,000 warrants exercisable at $8.02 per warrant, due to their anti-dilutive impact.

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

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

At-The-Market ("ATM") 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, potential use of proceeds, customary black-out restrictions, and whether we have any material inside inform ation. The agreement can be terminated by us at any time. Any sales of shares under the agreement are registered under the Securities Act of 1933, as amended, pursuant to a shelf registration statement on Form S-3. During the three months ended June 30, 2025, we sold 29,008,536 shares under t he agreement for proceeds of $174.1 million, net of commissions and fees of $2.7 million. There were no sales in the first quarter. See Note 13 for more information.

Stock-based Compensation Plans

Stock-based compensation expense for restricted stock units and performance-based grants to employees, totaled $3.0 million and $4.9 million for the three and six months ended June 30, 2025, respectively, and $3.0 million and $4.1 million for the three and six months ended June 30, 2024, respectively. At June 30, 2025, there was $16.1 million of unrecognized stock-based compensation cost which is expected to be recognized over a weighted-average remaining vesting period of 1.6 years.

The following table summarizes the stock-based compensation grants awarded during the six months ended June 30, 2025:

Grant date |  | Award type |  | Number granted |  |  | Grant date fair value per share

Pursuant to our directors stock plan 179,836 shares and 145,687 shares with a value of $1 million and $0.8 million were awarded to our directors and recorded as stock-based compensation expense during the three and six months ended June 30, 2025 and June 30, 2024, respectively. During the three and six months ended June 30, 2024, 10,831 shares with a value $0.05 million were paid to our interim CEO as part of her compensation.

In connection with the vesting of incentive compensation, certain 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 and six months ended June 30, 2025, we withheld 151,976 shares valued at approximately $0.9 million, or approximately $5.82 per share. During the six months ended June 30, 2024, we withheld 277,966 shares valued at approximately $1.2 million, or approximately $4.31 per share.

Common Stock Dividends

During the first two quarters of 2025, our Board of Directors have declared and we have paid a quarterly dividend of $0.00375 per common share, pursuant to our dividend policy.

On May 3, 2024 we entered into an amended revolving credit agreement with various financial institutions (the "Lenders"), which provided the Company with borrowing capacity up to $225 million with a maturity date of July 21, 2028 (accelerated to August 15, 2027 if our Senior Notes are not refinanced by that date).

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 June 30, 2025, we had net draws of $39.0 million outstanding at an inter est rate of 6.7%, and $6.7 million of outstanding letters of credit under the Credit Agreement. 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 June 30, 2025.

Note 8. Derivative Instruments

General

Our current risk management policy provides that up to 75% of five years of our foreign currency, and 100% of our metals 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, for which we have a program to manage our exposure to fluctuations 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, and only those related to Casa Berardi are designated as cash flow hedges. As of June 30, 2025, we have a total of 274 forward contracts outstanding to buy a total of CAD $234.1 million having a notional amount of USD $170.0 million to hedge the following exposures for 2025 through 2026:

•
Forecasted cash operating costs at Casa Berardi and Keno Hill of CAD $131.5 million at an average CAD-to-USD exchange rate of 1.351.
•
Forecasted capital expenditures at Casa Berardi of CAD $9.5 million at an average CAD-to-USD exchange rate of 1.3421.
•
Forecasted capital expenditures at Keno Hill of CAD $40.3 million at an average CAD-to-USD exchange rate of 1.4049.
•
Forecasted exploration expenditures at Keno Hill of CAD $6.7 million at an average CAD-to-USD exchange rate of 1.3975.
•
Forecasted Corporate costs of CAD $6.1 million at an average CAD-to-USD exchange rate of 1.3718.

As of June 30, 2025 and December 31, 2024, we recorded the following balances for the fair value of the foreign currency forward contracts (in millions):

|  | June 30, |  |  | December 31, |
Balance sheet line item: |  | 2025 |  |  | 2024 |
Other current assets |  | $ | 3.7 |  |  | $ | — |

Other current liabilities |  | $ | (1.1 | ) |  | $ | (8.2 | )
Other non-current liabilities |  | $ | (0.1 | ) |  | $ | (2.0 | )

Net unrealized losses of $1.4 million related to the effective portion of the foreign currency forward contracts designated as hedges are included in accumulated other comprehensive (loss) income as of June 30, 2025. Unrealized gains and losses will be transferred from accumulated other comprehensive (loss) income to current earnings as the underlying operating expenses are recognized. We estimate $1.2 million in net unrealized losses included in a ccumulated other comprehensive (loss) income as of June 30, 2025 will be reclassified to current earnings in the next twelve months.

Net realized losses of $1.0 million and $2.8 million for the three and six months ended June 30, 2025, and net realized losses of $1.1 million and $1.5 million for the three and six months ended June 30, 2024, on contracts related to underlying expenses which have been recognized were transferred from accumulated other comprehensive (loss) income and included in cost of sales and other direct production costs.

Net gains of $5.4 million and $5.5 million for the three and six months ended June 30, 2025, and net losses of $0.5 million and $2.4 million for the three and six months ended June 30, 2024, 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 income for the three and six months ended June 30, 2025 and 2024, respectively.

Metals Prices

We are currently using financially-settled forward contracts to manage our 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 June 30, 2025 and December 31, 2024:

Since the first quarter of 2025, we have and continue to utilize financially-settled zero cost collars ("collars") to manage our exposure to changes in the price of silver contained in both our provisional and forecasted Keno Hill future concentrate shipments. These collars provide us a contractual right to receive at least the minimum price if market prices fall below this level, while limiting our potential gains to the maximum price under the collars, even if market prices rise higher. This strategy helps protect us from significant price drops while still allowing for some upside potential within this range. For the three and six months ended June 30, 2025, these collars had net losses of $0.8 million and $0.2 million, respectively. For accounting purposes, they are not designated as hedges.

The following table summarize the quantities of metals committed under collars at June 30, 2025.

Settlement Period |  | Production Protected |  |  | Minimum Price |  |  | Maximum Price |
|  | (ounces) |  |  | ($) |  |  | ($) |
Contracts on provisional sales |  |  |  |  |  |  |  |  |
2025 settlements |  |  | 100,000 |  |  |  | 33.50 |  |  |  | 35.43 |

2026 settlements |  |  | 150,000 |  |  |  | 32.00 |  |  |  | 49.42 |

We recorded the following balances for the fair value of the forward metals and collar contracts as of June 30, 2025 and December 31, 2024 (in millions):

|  | June 30, |  |  | December 31, |
Balance sheet line item: |  | 2025 |  |  | 2024 |
Other current assets |  | $ | 10.2 |  |  | $ | 11.5 |
Other non-current assets |  | $ | 2.4 |  |  | $ | 6.6 |
Other current liabilities |  | $ | (0.5 | ) |  | $ | — |
Other non-current liabilities |  | $ | — |  |  | $ | — |

Net realized and unrealized gains of $14.5 million related to the effective portion of the forward metals contracts designated as hedges were included in accumulated other comprehensive income (loss) as of June 30, 2025. 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 $13.4 million in net realized and unrealized gains included in accumulated other comprehensive income (loss) as of June 30, 2025 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, of which $0.2 million remains to be recognized during the remainder of the year.

We recognized a net gain of $3.3 million, including a $3.5 million gain transfe rred from accumulated other comprehensive income (loss), and a net loss of $12.5 million, including a $3.0 million gain transferred from accumulated other comprehensive income (loss) during the three months ended June 30, 2025 and 2024, respectively. We rec ognized a net loss of $2.0 million, including a $5.7 million gain tra nsferred from accumulated other comprehensive income (loss), and a net loss of $9.4 million, including a $4.9 million gain transferred from accumulated other comprehensive income (loss) during the six months ended June 30, 2025 and 2024, respectively.

20

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 June 30, 2025, 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 $3.0 million as of June 30, 2025, which includes accrued interest but excludes any adjustment for nonperformance risk. If we were in breach of any of these provisions at June 30, 2025, we could have been required to settle our obligations under the agreements at their termination value of $3.0 million.

Note 9. Fair Value Measurement

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

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

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.

21

Our non-current investments consist of marketable equity securities of mining companies 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 and Keno Hill operations (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 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 June 30, 2025, our Senior Notes and IQ Notes were recorded at their carrying value o f $472.6 mill ion and $35.4 million, respectively, net of unamortized initial purchaser discount/premium and issuance costs. The estimated fair values of our Senior Notes and IQ No tes were $479.6 million a nd $36.8 million, respectively, at June 30, 2025. Quoted market prices, which are considered to be Level 1 inputs, are utilized to estimate fair values of the Senior Notes. Unobservable inputs which are considered to be Level 3, including an assumed current ann ual yield of 6.87%, 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 $39.0 million.

Note 11. Commitments, Contingencies and Obligations

San Mateo Creek Basin, New Mexico

In July 2018, the Environmental Protection Agency ("EPA") informed Hecla Limited that it and several other potentially responsible parties (“PRPs”) may be liable for cleanup of 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. At the time, the EPA stated it had incurred approximately $9.6 million in response costs. Also, in May, 2022 and August, 2024, Hecla Limited received a letter from a PRP notifying Hecla Limited that other PRPs may 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

22

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.

Debt

See Note 7 for information on the commitments related to our debt arrangements as of June 30, 2025.

Indirect Taxes

In May 2024, our Keno Hill subsidiary received a notice of assessment ("NOA") for goods and services tax ("GST") on its 2023 sales for CAD $1,973,181 from the Canada Revenue Agency ("CRA"). As Keno Hill's sales are to a non-Canadian party, we do not believe Keno Hill is subject to collect and remit GST, and we have disputed the NOA and proposed audit adjustments. On April 30, 2025, the CRA advised that they agreed with our position and the matter is resolved.

Other Commitments

Our contractual obligations as of June 30, 2025 included open purchase orders and commitments of $12.3 million, $5.9 million, $8.4 million, $10.4 million and $4.5 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 $19.7 million relating to scheduled payments on finance leases, including interest, primarily for equipment at our operations, and total commitments of $12.0 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 June 30, 2025, we had surety bonds totaling $218.9 million and letters of credit totaling $6.7 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.

O verview

Hecla Mining Company stands as North America's leading silver producer, with a rich heritage dating back to 1891. Our operations at Greens Creek, Lucky Friday and Keno Hill combined to produce 35% of 2024 silver production in the U.S. and Canada, complemented by significant gold production from Casa Berardi and Greens Creek. We began ramp-up of the Keno Hill mill during the second quarter of 2023 after acquiring it in September 2022. Our strategic positioning in the stable jurisdictions of U.S. and Canada provides us with distinct operational advantages and reduced political risk compared to our global peers. Our operational and strategic framework centers on four core pillars:

1.
Achieving operational excellence through standardized systems and continuous improvement
2.
Optimizing our portfolio through strategic reviews and targeting highest risk-adjusted return projects
3.
Intensifying our focus on financial discipline with a rigorous capital allocation framework
4.
Leveraging our position as North America's largest silver producer to meet growing demand from green technology markets

Second Quarter 2025 Highlights

Operational Achievements:

•
Strong Production - The Company produced 4.5 million ounces of silver with increased silver production at Greens Creek and Lucky Friday, compared to the second quarter of 2024, partly offset by lower silver production at Keno Hill due to lower tons milled. Produced 45,895 ounces of gold, an increase over the second quarter of 2024 and the first quarter of 2025, driven by higher grades and recoveries at Greens Creek and the continuation of underground mining at Casa Berardi.
•
Lucky Friday Milestone - Set a new quarterly milling record at Lucky Friday of 114,475 tons, beating the prior record set in the first quarter of the current year.

Financial Performance:

•
Revenue Generation - Generated record sales of $304 million a 24% increase over the comparable period sales.
•
Continuous Improvement - Keno Hill generated gross profit of $0.2 million, the second consecutive quarter with gross profit.
•
Shareholder Returns - Generated net income applicable to common stockholders of $57.6 million, compared to $27.7 million in the comparable 2024 period and returned $2.2 million in dividends to common stockholders.
•
Investment in Operations - Made capital expenditures of approximately $58.0 million, including $8.4 million at Greens Creek, $15.9 million at Lucky Friday, $15.4 million at Casa Berardi and $17.0 million at Keno Hill.
•
Strengthening Balance Sheet - Raised net proceeds of $174.1 million through the use of our ATM program.

Exploration:

•
Underground exploration at Greens Creek Galagher Zone extended mineralization 550 feet down plunge from existing resource
•
At Keno Hill, identified new high-grade silver mineralization 500 feet down plunge from existing reserve
•
Surface exploration programs at Midas and Greens Creek are well underway

26

Year to date 2025 Highlights

Operational Achievements:

•
Consistent Production - Progress at key operations delivering 8.6 million ounces of silver with increased silver production at Lucky Friday, offsetting decreases at Greens Creek. Produced 80,127 ounces of gold, exceeding the comparable 2024 period.
•
Lucky Friday Milestone - At Lucky Friday, set quarterly milling record for the first half of the year with 223,220 tons milled.

Financial Performance:

•
Revenue Generation - Generated record sales of $565.4 million a 30% increase over the comparable period sales.
•
Continuous Improvement - Turned Keno Hill profitable for the first time under our ownership, delivering $1.3 million in gross profit.
•
Shareholder Returns - Generated net income applicable to common stockholders of $86.3 million , compared to net income of $21.8 million in the comparable 2024 period and returned $4.7 million in dividends to common stockholders.
•
Investment in Operations - Made capital expenditures of approximately $112.1 million, including $19.2 million at Greens Creek, $31.4 million at Lucky Friday, $31.6 million at Casa Berardi and $27.5 million at Keno Hill.
•
Strengthening Balance Sheet - Raised net proceeds of $174.1 million through the use of our ATM program.

External Factors that Impact our Results

Our financial results vary as a result of fluctuations in market prices primarily for silver and gold and, to a lesser extent, zinc, lead and copper. World market prices for these commodities have fluctuated historically and are affected by numerous factors beyond our control. Although we have not been materially impacted to date, our financial results could in the future be materially impacted by the introduction of tariffs and other global restraints on trade. Historically our US operations have had significant sales into China and Canada, and each of those countries is or could be subject to tariffs, and each has or may retaliate in kind. Notwithstanding these recent developments, we believe that the outlook for precious metals fundamentals in the medium- and long-term is favorable due to macro-economic factors such as lower interest rate expectations, geopolitical uncertainty and global growth expectations, which have resulted in significant volatility in the financial and commodities markets, including the precious metals market. See Part II, Item 1A. “Risk Factors” of this Form 10-Q and Item 1A. “Risk Factors” contained in Part I of our annual report on Form 10-K for the year ended December 31, 2024 ("2024 Form 10-K"), for further discussion. Because we cannot control the price of our products, except to the extent we have entered into hedging transactions, the key measures that management focuses on in operating our business are production volumes, payable sales volumes, Cash Cost, After By-product Credits, per Ounce (non-GAAP) and All-In Sustaining Cost, After By-product Credits, per Ounce (“AISC”) (non-GAAP), operating cash flows, capital expenditures, free cash flow (non-GAAP) and adjusted EBITDA (non-GAAP). The average realized prices for all metals sold by us continued to exhibit significant volatility during the period. We have also experienced significant cost inflation across our operations, principally associated with higher energy prices, increased costs for other consumables such as reagents, explosives and steel, and higher labor and contractor costs.

C onsolidated Results of Operations

Total sales for the three and six months ended June 30, 2025 and 2024 were as follows:

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

Environmental remediation services revenue is generated by performing remediation work in the historical Yukon Territory mining district on behalf of the Canadian government. The scope and estimated cost of all work is agreed to in advance by the Canadian government, and the expenses incurred are essentially passed through to the government for reimbursement with minimal margin generated by us in performing this work.

The fluctuation in sales for the three and six months ended June 30, 2025 compared to the same periods in 2024 was primarily due to the following:

•
Higher average realized prices for precious metals, partly offset by lower realized lead prices for both periods and zinc for the three months ended June 30, 2025, compared to the same periods in 2024. The table below summarizes average spot prices and our average realized prices for the commodities we sell:

Average realized prices typically differ from average market prices primarily because concentrate sales are generally recorded as revenues at the time of shipment at forward prices for the estimated month of settlement, which differ from average market prices. Due to the time elapsed between shipment of concentrates and final settlement with the customers, we must estimate the prices at which sales of our metals will be settled. Previously recorded sales are adjusted to estimated settlement metals prices each period through final settlement. We recorded net positive price adjustments to provisional settlements of $4.2 million and $11.0 million for the three months ended June 30, 2025 and 2024, and $11.1 million and $14.5 million for the six months ended June 30, 2025 and 2024, respectively. The price adjustments related to silver, gold, zinc, lead and copper contained in our concentrate shipments were partially offset by gains and losses on forward contracts for those metals. See Note 8 of Notes to Condensed Consolidated Financial Statements (Unaudited) for more information. The gains and losses on these contracts are included in revenues and impact the realized prices for silver, gold, lead, zinc and copper. Realized prices are calculated by dividing gross revenues for each metal (which include the price adjustments and gains and losses on the forward contracts discussed above) by the payable quantities of each metal included in concentrate, doré and carbon material shipped during the period.

•
The positive effect of higher metal prices was partially offset by lower silver sales volumes during the three and six months ended June 30, 2025 compared to the comparable 2024 period. Lower silver ounces sold were related to reduced production at

28

Greens Creek in the first quarter and lower production at Keno Hill due to lower throughput. Though gold production is higher than the comparable 2024 periods, an inventory build at Casa Berardi during the quarter resulted in gold ounces sold being largely consistent with 2024. See The Greens Creek Segment, The Lucky Friday Segment, The Keno Hill Segment, and Casa Berardi Segment sections below for more information on metal production and sales volumes at each of our operating segments. Total metals production and sales volumes for each period are shown in the following table:

|  |  |  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |
|  |  |  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |

|  | Payable tons sold |  |  | 108 |  |  |  | — |  |  |  | 152 |  |  |  | — |

The difference between what we report as “ounces/tons produced” and “payable ounces/tons sold” is attributable to the difference between the quantities of metals contained in the concentrates we produce versus the portion of those metals actually paid for by our customers according to the terms of our sales contracts. Differences can also arise from inventory changes incidental to shipping schedules, or variances in ore grades which impact the amount of metals contained in concentrates produced and sold.

For the three and six months ended June 30, 2025, Other includes sales of $6.6 million and $13.7 million and total cost of sales of $6.6 million and $13.7 million respectively, from our environmental remediation services in the Yukon. For the three and six months ended June 30, 2024, Other includes sales of $3.4 million and $7.8 million and total cost of sales of $3.6 million and $7.5 million, respectively.

While revenue from zinc, lead, copper and gold by-products is significant, we believe that identification of silver as the primary product of Greens Creek, Lucky Friday and Keno Hill is appropriate because:

•
silver has historically accounted for a higher proportion of revenue than any other metal and is expected to do so in the future;
•
we have historically presented Greens Creek and Lucky Friday as primary silver producers, based on the original analysis that justified putting the project into production, and the same analysis applies to Keno Hill. Further we believe that consistency in disclosure is important to our investors regardless of the relationships of metals prices and production from year to year;
•
metallurgical treatment maximizes silver recovery;
•
the Greens Creek, Lucky Friday and Keno Hill deposits are massive sulfide deposits containing an unusually high proportion of silver; and
•
in most of their working areas, Greens Creek, Lucky Friday and Keno Hill utilize selective mining methods in which silver is the metal targeted for highest recovery.

Accordingly, we believe the identification of gold, lead, zinc and copper as by-product credits at Greens Creek, Lucky Friday and Keno Hill is appropriate because of their lower economic value compared to silver and due to the fact that silver is the primary product we intend to produce at those locations. In addition, we have not consistently received sufficient revenue from any single by-product metal to warrant classification of such as a co-product.

We periodically review our revenues to ensure that reporting of primary products and by-products is appropriate. Because for Greens Creek, Lucky Friday and Keno Hill we consider zinc, lead, gold and copper to be by-products of our silver production, the values of these metals offset operating costs within our calculations of Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce. We currently do not report Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce for our Keno Hill operation as it is in the production ramp-up phase and has not met our definition of commercial production. We define an operation as being in commercial production upon achievement of the following criteria:

•
Completion of operational commissioning of each major mine and mill component;
•
Demonstrated ability to mine and mill consistently and without significant interruption, defined as 75% of historical production levels or mill design capacity over a period of 90 days;
•
Silver recoveries are at or near expected steady-state production levels;

30

•
All major capital expenditures have been completed; and
•
A significant portion of available funding is directed towards operating activities.

Currently we meet only one of the above criteria - silver recoveries are at expected steady-state production levels. Determination of when these criteria have been met requires the use of judgment, and our definition of commercial production may differ from that of other mining companies.

As Keno Hill has not yet been determined to be in commercial production, its costs and by-product credits are excluded from our consolidated Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce because (i) by definition it has not reached the sustaining stage and (ii) including its costs and by-product credits we believe would distort consolidated Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce of our operating silver mines that are in commercial production and operating as designed, and would not facilitate a meaningful comparison of our performance versus that of our peers who do not report such metrics for mines that are not in commercial production.

We believe the identification of silver as a by-product credit is appropriate at Casa Berardi because of its lower economic value compared to gold and due to the fact that gold is the primary product we produce there. In addition, we do not receive sufficient revenue from silver at the Casa Berardi mine to warrant classification of such as a co-product. Because we consider silver to be a by-product of our gold production at Casa Berardi, the value of silver offsets operating costs within our calculations of Cash Cost, After By-product Credits, per Gold Ounce and AISC, After By-product Credits, per Gold Ounce.

We reported net income applicable to common stockholders of $57.6 million for the three months ended June 30, 2025, compared to a net income applicable to common stockholders of $27.7 million in the comparable period in 2024. The following were the significant drivers of the change:

•
Consolidated gross profit increased by $68.1 million. See The Greens Creek Segment, The Lucky Friday Segment, The Keno Hill Segment, and The Casa Berardi Segment sections below for a discussion on the key drivers by operation.
•
General and administrative expenses decreased by $2.2 million due to the prior period containing compensation costs associated with the former CEO's retirement.
•
Ramp-up and suspension costs decreased by $1.4 million due to the current period containing no ramp-up costs for Keno Hill, as the site recorded gross profit, whereas in the prior period total cost of sales in excess of sales by $1.8 million were transferred to ramp-up and suspension costs.
•
Fair value adjustments, net increased by $4.6 million primarily due to $4.9 million in unrealized gains on our marketable equity securities portfolio and gains on undesignated derivative contracts of $4.7 million in the current period.

The positive movements mentioned above were partly offset by:

•
Other operating expense (income), net increased by $16.7 million primarily due to the prior period containing $17.8 million of insurance proceeds received related to the Lucky Friday fire.
•
Exploration and pre-development expense increased by $2.1 million in the current period with exploration activity primarily related to Keno Hill, Greens Creek and the Nevada properties.
•
Net foreign exchange loss increased by $6.2 million to a loss of $3.5 million, compared to a gain of $2.7 million in the comparable period as the US dollar weakened against the Canadian dollar.
•
Income and mining tax expense increased by $23.5 million due to higher taxable income generated by our US tax group.

We reported net income applicable to common stockholders of $86.3 million for the six months ended June 30, 2025, compared to a net income applicable to common stockholders of $21.8 million in the comparable period in 2024. The following were the significant drivers of the change:

•
Consolidated gross profit increased by $122.9 million. See The Greens Creek Segment, The Lucky Friday Segment, The Keno Hill Segment, and The Casa Berardi Segment sections below for a discussion on the key drivers by operating unit.
•
Ramp-up and suspension costs decreased by $12.6 million due to the current period containing no ramp-up costs for Keno Hill, as the site recorded gross profit, whereas in the prior period total cost of sales in excess of sales by $10.4 million were transferred to ramp-up and suspension costs. In addition, the prior period included $2.2 million of suspension costs related to the temporary suspension of operations at Lucky Friday due to the underground fire prior to the restart of operations on January 8, 2024.
•
Interest expense decreased by $2.5 million due to lower draws on the revolving credit facility during the current year.
•
Fair value adjustments, net increased by $10.1 million primarily due to $8.5 million in unrealized gains on our marketable equity securities portfolio and $4.7 million of gains on undesignated derivative contracts in the current period.

The positive movements mentioned above were partly offset by:

31

•
Other operating (income) expense, net increased by $34.7 million primarily due to the prior period containing $35.2 million of insurance proceeds received related to the Lucky Friday fire.
•
Net foreign exchange loss increased by $10.5 million, to a loss of $3.9 million compared to a gain of $6.7 million in the comparable period, driven by a weakening of the US dollar against the Canadian dollar during the current year.
•
Income and mining tax expense increased by $37.8 million due to higher taxable income generated by our US tax group.

The $24.2 million increase in gross profit for the three months ended June 30, 2025, compared to the same period in 2024 was primarily due to higher realized sales prices for silver and gold, in addition to higher sales volumes for all metals, except lead.

Capital additions in the current quarter were $3.3 million lower than the prior year period and included $2.8 million for primary ore access development, $2.0 million for mine development and $1.8 million for mining equipment and related costs.

Production of all metals increased during the three months ended June 30, 2025, primarily due to a combination of higher tons milled and higher grades.

The $45.3 million increase in gross profit for the six months ended June 30, 2025, compared to the same period in 2024 was primarily due to higher realized sales prices for silver, gold and lead, partially offset by lower metals sales volumes for all metals, except zinc.

Capital additions during the year were $1.4 million lower than the prior year period and included $6.0 million for primary ore access development, $3.4 million for mine development, $2.8 million for mining equipment and $1.7 million for definition drilling.

Silver production during the six months ended June 30, 2025, declined primarily due to a combination of lower tons milled reflecting a combination of lower heading availability, long hole mining and lower grade ore during the first quarter of 2025 which outweighed an improvement in silver production during the second quarter of 2025. Production of gold, lead and zinc are higher during the current year primarily due to higher grades.

Gross profit increased by $0.4 million for the three months ended June 30, 2025 compared to the comparable period in 2024, reflecting a combination of higher sales volumes for all metals due to higher milled tons. Higher realized prices for silver and zinc also positively contributed to the higher gross profit, however this benefit was partly offset by higher contractor, consumables and maintenance costs reflecting the higher volumes produced and sold, and higher profit sharing costs under the collective bargaining agreement.

Gross profit increased by $11.8 million for the six months ended June 30, 2025 compared to the comparable period in 2024, reflecting a combination of higher sales volumes for all metals due to a full six months of production in 2025, compared to 2024 when operations did not resume until January 9, 2024, following suspension of operations in August 2023, due to the underground fire in the secondary egress. Higher realized prices for silver and zinc also positively contributed to the higher gross profit, however this benefit

We have not disclosed cost per ounce statistics for the Keno Hill operation as it is in the production ramp-up phase and has not met our definition of commercial production. See above "Consolidated Results of Operations" for our definition of commercial production. Determination of when those criteria have been met requires the use of judgment, and our definition of commercial production may differ from that of other mining companies.

We acquired our Keno Hill operations as part of the Alexco Resource Corp. acquisition in September 2022 and have focused on development activities and began ramp-up of the mill during the second quarter of 2023. The average mill throughput during the six months ended June 30, 2025, was 299 tons per day (the mine is currently permitted to a maximum of an average of 440 tons per day),

37

with silver grades milled of 29.0 ounces per ton. During the first quarter of the year, the mill relied on the existing ore stockpiles as the mine continues to focus on development and ramp up to higher tonnage rates with mining rates of 263 tons per day during the first six months ended June 30, 2025, with material sourced from both the Bermingham and Flame and Moth deposits. Mill throughput, while currently steady, has been negatively impacted by last year's events as described below.

During the three months ended June 30, 2025 and 2024, Keno Hill recorded sales of $26.1 million and $29.0 million, respectively, with the decrease due to lower metals sales volumes, partly offset by higher realized prices. As a result of higher metals prices, Keno Hill generated a gross profit of $0.2 million during the three months ended June 30, 2025, and did not transfer any total cost of sales to ramp-up and suspension costs. During the second quarter of 2024, total cost of sales in excess of sales of $1.8 million were reclassified to ramp-up and suspension costs in the Condensed Consolidated Statements of Operations and Comprehensive Income, (Unaudited). During the quarter, Keno Hill recorded capital additions of $17.0 million, related to mine development and other mining equipment purchases.

During the six months ended June 30, 2025 and 2024, Keno Hill recorded sales of $43.0 million and $39.8 million, respectively, with the increase in sales attributable to higher realized sales prices, partly offset by lower volumes sold. As a result of higher revenues, Keno Hill generated a gross profit of $1.3 million during the six months ended June 30, 2025, and did not transfer any total cost of sales to ramp-up and suspension costs. During the six months ended June 30, 2024, total cost of sales in excess of sales of $10.4 million were reclassified to ramp-up and suspension costs in the Condensed Consolidated Statements of Operations and Comprehensive Income, (Unaudited). During the six months ended June 30, 2025, Keno Hill recorded capital additions of $27.5 million, primarily related to mine development and the Bermingham backfill plant.

From commencement of production until late August, 2024, ore production and mill throughput generally increased as planned, leading to increased levels of production (though still not reaching the permitted capacity at the mill). However, starting in mid-2024 and continuing today, Keno Hill has been impacted by external events which have affected permitting, projects and production, and delayed our ability to reach sustained, profitable production. In late June 2024, an unrelated, third party, Victoria Gold, experienced a heap leach failure at its Eagle Mine which is located near Keno Hill. This incident had several immediate and ongoing impacts on our operations. The primary impact was we were forced to suspend milling operations at Keno Hill between August 27 and October 26 due to delays in receiving authorizations and permits because the focus of the Yukon Government (“YG”) and the First Nation of Na-Cho Nyäk Dun (“FNNND”) was on the Eagle Mine incident response and not on routine permitting matters. Mill operations and design and construction projects resumed during the fourth quarter of 2024. Our original planned schedule for permitting and projects has been extended, but we are taking steps, including working with regulators, to establish a viable schedule for our operational plans.

An ongoing impact of the Eagle Mine incident is the FNNND's public position on mining, which has evolved from a call to halt all mining activity to support of environmentally responsible mining practices. We continue to strengthen our partnership with the FNNND - which is important because Keno Hill is within their Traditional Territory - through enhanced environmental stewardship and community engagement initiatives, building on their support for responsible mining practices.

Then, starting in late October 2024, Keno Hill began experiencing power curtailments when Yukon Energy experienced a turbine failure at its hydroelectric plant in Whitehorse. That failure and Yukon Energy’s resulting focus on line maintenance, combined with cold temperatures in the Yukon (and the resulting increase in demand for power), caused Yukon Energy to reduce power to Keno Hill, resulting in the operation’s inability to fully power the mine and mill on several occasions in late 2024 and for 8 days in the first quarter of 2025. Temporary power constraints in the Yukon region impacted approximately 130,000 ounces of silver production and labor costs for idled employees of approximately $0.5 million through June 30, 2025. These conditions improved in the second quarter of 2025 when we experienced no power disruptions by Yukon Energy, nor do we expect any disruptions while the weather remains warm, except that we expect a 6-day outage in August 2025 when the turbine at Yukon Energy's hydroelectric plant in Whitehorse is scheduled to be fixed. There can be no assurance that Keno Hill will not face power supply constraints in the future.

Permitting is one of the most important factors in our ability to reach sustainable, profitable production at Keno Hill. Increased production means a need for increased tailings storage, waste storage, water treatment, camp space and reliable power, all of which are typical requirements for mining companies in the expansion phase. These projects require new or modified permits, as well as the capital to implement them. Although we continue to make progress on these normal-course permitting matters, we have yet to make up for the delays described above. We also continue to face operational challenges such as work force availability, dilution, execution of projects, limited camp space, and the ramp-up of the Company's environmental remediation services group activities in the summer (which adds incremental demand on Keno Hill's infrastructure and resources, most notably camp space). As a result, we continue to

38

project 2025 silver production to be comparable to 2024 levels. The projected flat production levels at Keno Hill for 2025 should allow us to focus on (i) permitting, (ii) stakeholder outreach and ensuring we have local support, (iii) projects such as tailings storage expansion and the construction of a cemented tails batch plant, (iv) mine development and (v) meeting the above-mentioned operational challenges.

As stated above, Keno Hill has generated marginal profits for us at current throughput rates and prices. Our immediate focus is to advance permits and successfully execute infrastructure projects, with the goal of putting the mine on a path toward achieving its current permitted capacity of 440 tons per day which, at current prices, we project would generate positive free cash flow, while preserving expansion optionality beyond 440 tons per day. To reach 440 tons per day throughput, we would need to continue to mine ore from both the Bermingham deposit and the lower grade Flame & Moth deposit. Currently Keno Hill is not configured to sustainably produce 440 tons per day (although the mill has achieved that rate for multiple weeks on end during test run periods). Achieving 440 or higher tons per day would require targeted infrastructure investments, obtaining permits, executing projects, mine development and maintaining community support. If any one of these were not to occur, or if prices were to decrease from current prices, Keno Hill as currently configured would not be profitable, and placing the operation on care and maintenance would be an option. See Item 1A. Risk Factors - We may not realize all of the anticipated benefits from our acquisitions, including our 2022 acquisition of Alexco in our 2024 Form 10-K.

Casa Berardi is advancing toward a more streamlined and efficient surface-only operation. The plan was to focus exclusively on the 160 pit by mid-2025, however following the significant increase in the gold price during the year to date, it was decided to continue to mine the easily accessible ore in the west underground mine, potentially through the end of 2025. This transition follows the continued successful extraction of higher-margin stopes from the west underground mine, positioning the mine for continued productivity and cost-effective mining. Our previously announced strategic review is ongoing and includes evaluating the following scenarios (i) sale of the asset, (ii) joint venturing the asset, (iii) spin-out of the asset, (iv) extending the underground mine, and (iv) accelerating future cash flows to capture part of the current record gold prices via a prepayment structure or other financing arrangement. If underground mining is not extended, Casa Berardi is expected to only produce gold from the 160 open pit, and at lower volumes than historic production levels, with production expected to conclude at the 160 open pit in 2027. Casa Berardi is transitioning to a new phase focused on developing the Principal and West Mine Crown Pillar open pits. This strategic repositioning is expected to optimize long-term value, with production anticipated to resume following successful permitting and development during a production gap expected

39

between 2027 and 2032. Upon successful completion of permitting, design, and construction of the new open pits (which is not assured), we expect Casa Berardi to generate substantial free cash flow at current gold prices when production resumes. This long-term approach aligns with our commitment to maximizing the value of our assets through strategic mine planning and operational flexibility.

Gross profit increased by $43.0 million to $34.2 million for the three months ended June 30, 2025, compared to a gross loss of $8.7 million in the comparable period in 2024. The increase in gross profit is primarily related to higher realized prices and gold ounces sold, partly offset by higher contractor costs. The prior period gross loss also included higher depreciation expense related to accelerated depreciation of the west underground mine. Capital additions increased by $3.0 million to $15.4 million during the quarter, compared to the same period in 2024, and primarily related to a tailings dam raise.

Gross profit increased by $65.0 million to $39.6 million for the six months ended June 30, 2025, compared to a gross loss of $25.4 million in the comparable period in 2024. The increase in gross profit is primarily related to higher realized prices and gold ounces sold, partly offset by higher contractor costs. The prior period gross loss also included higher depreciation expense related to accelerated depreciation of the west underground mine and a product inventory net realizable value write down of $6.3 million. Capital additions increased by $5.9 million to $31.6 million during the year, compared to the same period in 2024, and primarily related to a tailings dam raise.

Although Casa Berardi generated gross profits during the last four quarters and free cash flow during the current quarter, it reported gross losses during the prior three fiscal years. This lack of profitability and free cash flow generation, the expected hiatus in future production discussed above, the uncertainty surrounding permitting and pit design and construction, and the time involved to resolve these uncertainties, has caused us to undertake a review of how Casa Berardi fits into the Company's future strategy. While it is possible we may continue down the path towards future production at the Principal and West Mine Crown Pillar pits, we are also examining potential strategic alternatives as described above.

The decrease in Cash Cost After By-product Credits, per Gold Ounce, and AISC, After By-product Credits, per Gold Ounce for the three months ended June 30, 2025, compared to the same period in 2024 was primarily due to higher gold production.

The increase in Cash Cost After By-product Credits, per Gold Ounce, and AISC, After By-product Credits, per Gold Ounce for the three and six months ended June 30, 2025, compared to the same period in 2024 was primarily due to higher production costs, partly offset by higher gold production. AISC, After By-product Credits, per Gold Ounce benefited from lower sustaining capital over the comparable period in 2024.

Corporate Matters

Income Taxes

During the three and six months ended June 30, 2025, an income and mining tax provision of $32.6 million and $48.7 million, resulted in an effective tax rate of 36.1% and 36.0%, respectively. This compares to an income and mining tax provision of $9.1 million and $10.9 million, which resulted in an effective tax rate of 24.6% and 33.0%, respectively, for the three and six months ended June 30, 2024. The comparability of our income and mining tax provision and effective tax rate for the reported periods was impacted by multiple factors, primarily: (i) mining taxes; (ii) variations in our income before income taxes; (iii) geographic distribution of that income; (iv) foreign exchange rates including non-recognition of foreign exchange gains and losses; (v) percentage depletion; and (vi) the non-recognition of tax assets. The effective tax rate will fluctuate, sometimes significantly, period to period. The change in the effective tax rate during the three and six months ended June 30, 2025, compared to the comparable periods in 2024 is primarily related to the reported consolidated income (loss) as well as the losses incurred at our consolidated Alexco subsidiaries, and our Nevada subsidiaries, for which no tax benefit is recognized due to uncertainty surrounding our ability to utilize these future tax benefits.

Each reporting period we assess our deferred tax balances based on a review of long-range forecasts and quarterly activity. A valuation allowance is provided for deferred tax assets for which it is more likely than not the related tax benefits will not be realized. We analyze our deferred tax assets and, if it is determined that we will not realize all or a portion of our deferred tax assets, we record or increase a valuation allowance. Conversely, if it is determined we will ultimately more likely than not be able to realize all or a portion of the related benefits for which a valuation allowance has been provided, all or a portion of the related valuation allowance will be reduced. There are a number of factors that impact our ability to realize our deferred tax assets. Valuation allowances are provided on deferred tax assets in Nevada, Mexico, and certain Canadian jurisdictions. For additional information, please see risk factors Our accounting and other estimates may be imprecise and Our ability to recognize the benefits of deferred tax assets related to net operating loss carryforwards and other items is dependent on future cash flows generating taxable income in Item 1A - Risk Factors in our 2024 Form 10-K.

Reconciliation of Total Cost of Sales to Cash Cost, Before By-product Credits and Cash Cost, After By-product Credits (non-GAAP) and All-In Sustaining Cost, Before By-product Credits and All-In Sustaining Cost, After By-product Credits (non-GAAP)

The tables below present reconciliations between the most comparable GAAP measure of total cost of sales to the non-GAAP measures of (i) Cash Cost, Before By-product Credits, (ii) Cash Cost, After By-product Credits, (iii) AISC, Before By-product Credits and (iv) AISC, After By-product Credits for our operations and for the Company for the three and six months ended June 30, 2025 and 2024.

Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce are measures developed by precious metals companies (including the Silver Institute and the World Gold Council) in an effort to provide a uniform standard for comparison purposes. There can be no assurance, however, that these non-GAAP measures as we report them are the same as those reported by other mining companies.

Cash Cost, After By-product Credits, per Ounce is an important operating statistic that we utilize to measure each mine's operating performance. We use AISC, After By-product Credits, per Ounce as a measure of our mines' net cash flow after costs for reclamation and sustaining capital. This is similar to the Cash Cost, After By-product Credits, per Ounce non-GAAP measure we report, but also includes reclamation and sustaining capital costs. Current GAAP measures used in the mining industry, such as cost of goods sold, do not capture all the expenditures incurred to discover, develop and sustain silver and gold production. Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce also allow us to benchmark the performance of each of our mines versus those of our competitors. As a silver and gold mining company, we also use these statistics on an aggregate basis - aggregating the Greens Creek and Lucky Friday mines to compare our performance with that of other silver mining companies. Similarly, these statistics are useful in identifying acquisition and investment opportunities as they provide a common tool for measuring the financial performance of other mines with varying geologic, metallurgical and operating characteristics.

We have not disclosed cost per ounce statistics for the Keno Hill operation as it is in the production ramp-up phase and has not met our definition of commercial production. See above "Consolidated Results of Operations" for our definition of commercial production. Determination of when those criteria have been met requires the use of judgment, and our definition of commercial production may differ from that of other mining companies.

Cash Cost, Before By-product Credits and AISC, Before By-product Credits include all direct and indirect operating cash costs related directly to the physical activities of producing metals, including mining, processing and other plant costs, third-party refining expense, on-site general and administrative costs, royalties and mining production taxes. AISC, Before By-product Credits for each mine also includes reclamation and sustaining capital costs. AISC, Before By-product Credits for our consolidated silver properties also includes corporate costs for general and administrative expense and sustaining capital costs. By-product credits include revenues earned from all metals other than the primary metal produced at each unit. As depicted in the tables below, by-product credits comprise an essential element of our silver unit cost structure, distinguishing our silver operations due to the polymetallic nature of their orebodies.

In addition to the uses described above, Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce provide management and investors an indication of operating cash flow, after consideration of the average price received from production. We also use these measurements for the comparative monitoring of performance of our mining operations period-to-period from a cash flow perspective. We currently do not report Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce for our Keno Hill operation as it is in the ramp-up phase of production and accordingly it is excluded from our consolidated Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce.

Casa Berardi reports Cash Cost, After By-product Credits, per Gold Ounce and AISC, After By-product Credits, per Gold Ounce for the production of gold, their primary product, and by-product revenues earned from silver, which is a by-product at Casa Berardi. Only costs and ounces produced relating to units with the same primary product are combined to represent Cash Cost, After By-product Credits, per Ounce and AISC, After By-product Credits, per Ounce. Thus, the gold produced at Casa Berardi is not included as a by-product credit when calculating Cash Cost, After By-product Credits, per Silver Ounce and AISC, After By-product Credits, per Silver Ounce for the total of Greens Creek and Lucky Friday, our combined silver properties. Similarly, the silver produced at our other three units is not included as a by-product credit when calculating the gold metrics for Casa Berardi.

Financial Liquidity and Capital Resources

52

We have a disciplined cash management strategy of maintaining financial flexibility to execute our capital priorities and provide long-term value to our stockholders. Consistent with that strategy, we aim to maintain an acceptable level of net debt and sufficient liquidity to fund debt service costs, operations, capital expenditures, exploration and pre-development projects, while returning cash to stockholders through dividends and potential share repurchases.

At June 30, 2025, we had $296.6 million in cash and cash equivalents, of which $2.9 million was held in foreign subsidiaries' local currency that we anticipate utilizing for near-term operating, exploration or capital costs by those foreign subsidiaries. At June 30, 2025, we had $39.0 million drawn on our $225 million credit facility, and additional $6.7 million used for letters of credit, leaving $179.3 million for additional borrowings. We also have USD cash and cash equivalent balances held by our foreign subsidiaries that, if repatriated, may be subject to withholding taxes. We expect that there would be no additional tax burden upon repatriation after considering the cash cost associated with the withholding taxes. We believe that our liquidity and capital resources from our U.S. operations are adequate to fund our U.S. operations and corporate activities.

Pursuant to our common stock dividend policy described in Note 12 of Notes to Consolidated Financial Statements in our consolidated financial statements and notes for the year ended December 31, 2024, our Board of Directors declared and paid dividends on our common and preferred stock of $2.5 million and $5.0 million during the three and six months ended June 30, 2025, and $4.0 million and $8.0 million during the three and six months ended June 30, 2024, respectively. Our common stock dividend policy anticipates paying an annual minimum dividend of $0.015 per share. Prior to the first quarter of 2025, our dividend policy previously had an additional silver-linked component which tied the amount of declared common stock dividends to our realized silver price for the preceding quarter.

The declaration and payment of dividends on our common stock is at the sole discretion of our Board of Directors, and there can be no assurance that we will continue to declare and pay common stock dividends in the future.

Pursuant to our stock repurchase program described in Note 12 of Notes to Consolidated Financial Statements in our consolidated financial statements and notes for the year ended December 31, 2024, we are authorized to repurchase up to 20 million shares of our outstanding common stock from time to time in open market or privately negotiated transactions, depending on prevailing market conditions and other factors. The repurchase program may be modified, suspended or discontinued by us at any time. Whether or not we engage in repurchases from time to time may depend on a variety of factors, including not only price and cash resources, but customary black-out restrictions, whether we have any material inside information, limitations on share repurchases or cash usage that may be imposed by our credit agreement or in connection with issuances of securities, alternative uses for cash, applicable law, and other investment opportunities from time to time. As of June 30, 2025 and December 31, 2024, 934,100 shares had been purchased in prior periods at an average price of $3.99 per share, leaving 19.1 million shares that may yet be purchased under the program. We have not repurchased any shares since June 2014.

As discussed in Note 6 of Notes to Condensed Consolidated Financial Statements (Unaudited) pursuant to an equity distribution agreement dated February 18, 2021, as of June 30, 2025, there were 7,147,780 remaining shares of our common stock that we may offer and sell from time to time in “at-the-market” offerings. 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 share price, our cash resources, customary black-out restrictions, and whether we have any material inside information. The equity distribution agreement can be terminated by us at any time. Any sales of shares under that agreement are registered under the Securities Act of 1933, as amended, pursuant to a shelf registration statement on Form S-3. During the six months ended June 30, 2025, we sold 29,008,536 shares under the agreement. Subsequent to June 30, 2025, we sold an additional 6,949,792 shares, leaving 197,988 remaining shares of our common stock that may be sold under the equity distribution agreement.

As a result of our current cash balances, the performance of our current and expected operations, current metals prices, proceeds from potential at-the-market sales of common stock, and availability under our Credit Agreement, we believe we will be able to meet our obligations and other potential cash requirements during the next 12 months and beyond. Our obligations and other uses of cash may include, but are not limited to: debt service obligations related to the Senior Notes; principal and interest payments under our Credit Agreement; ramp up and suspension costs; capital expenditures at our operations; potential acquisitions of other mining companies or properties; regulatory matters; litigation; potential repurchases of our common stock under the program described above; and payment of dividends on common stock, if declared by our Board of Directors. The IQ Notes were fully repaid on July 9, 2025, and on August 1, 2025, we issued a notice of redemption for a portion of our Senior Notes. See Note 13 of Notes to Condensed Consolidated Financial Statements (Unaudited) for more information.

We currently estimate a range of approximately $222 to $242 million (before any lease financing) will be invested in 2025 on capital expenditures, primarily for equipment, infrastructure, and development at our mines, including $112.1 million already incurred as of June 30, 2025. We also estimate exploration and pre-development expenditures will total approximately $28.0 million in 2025, including $13.3 million already incurred as of June 30, 2025. Our expenditures for these items and our related plans for 2025 may change based upon our financial position, metals prices, and other considerations. Our ability to fund the activities described above will

53

depend on our operating performance, metals prices, our ability to estimate revenues and costs, sources of liquidity available to us, including the revolving credit facility (which requires compliance with certain financial and other covenants), and other factors. A sustained downturn in metals prices, significant increase in operational or capital costs or other uses of cash, poor results of our operating units, our inability to access the credit facility or the sources of liquidity discussed above, or other factors beyond our control could impact our plans.

We may defer some capital investment and/or exploration and pre-development activities, engage in asset sales or secure additional capital if necessary to maintain liquidity. We may also pursue additional acquisition opportunities, which could require additional equity issuances or other forms of financing. There can be no assurance that such financing will be available to us.

Our liquid assets include (in millions):

|  | June 30, 2025 |  |  | December 31, 2024 |
Cash and cash equivalents held in U.S. dollars |  | $ | 293.7 |  |  | $ | 24.5 |
Cash and cash equivalents held in foreign currency |  |  | 2.9 |  |  |  | 2.4 |

Total cash, cash equivalents and investments |  | $ | 340.0 |  |  | $ | 60.1 |

Cash and cash equivalents increased by $269.7 million in the first six months of 2025. Cash held in foreign currencies represents balances in Canadian dollars and Mexican Pesos. The value of non-current marketable equity securities increased by $10.2 million.

Cash provided by operating activities (in millions) |  | $ | 197.5 |  |  | $ | 95.8 |

Cash provided by operating activities for the six months ended June 30, 2025, of $197.5 million represents a $101.7 million increase compared to the $95.8 million of cash provided by operations during the same period of 2024. $62.8 million of the variance was attributable to higher income adjusted for non-cash items, reflecting higher net income driven by higher revenues, partly offset by lower non-cash depreciation, depletion and amortization expense, and a working capital improvement of $39.0 million primarily driven by lower accounts receivable and inventory, in addition to an accounts payable build.

During the six months ended June 30, 2025, we had net borrowings of $16.0 million on our revolving credit facility resulting in $39.0 million outstanding at an interest rate of 6.7% on June 30, 2025. In addition, during the six months ended June 30, 2025 and 2024:

•
we paid cash dividends on our common and preferred stock totaling $5.0 million and $8.0 million , respectively;
•
we made repayments on our finance leases of $4.2 million and$5.5 million, respectively; and
•
we issued stock under our ATM program described above for net proceeds of $174.1 million and $1.1 million, respectively.

(1)
Consists of open purchase orders and commitments of approximately $12.3 million, $5.9 million, $4.8 million, $10.4 million and $4.5 million for various capital and non-capital items at Greens Creek, Lucky Friday, Keno Hill, Casa Berardi and Other Operations, respectively.

(2)
The Credit Agreement provides for a $225 million revolving credit facility. We had net draws of $39.0 million and $6.7 million in letters of credit outstanding as of June 30, 2025. The amounts in the table above assume no additional amounts will be drawn in future periods, and include only the standby fee on the current undrawn balance and accrued interest. For more information on our credit facility, see Note 7 of Notes to Condensed Consolidated Financial Statements (Unaudited).

(3)
Includes scheduled finance lease payments of $1.8 million, $3.4 million, $9.3 million, and $3.2 million for equipment at Greens Creek, Lucky Friday, Casa Berardi, and Keno Hill, respectively.

(4)
We enter into operating leases in the normal course of business. Substantially all lease agreements have fixed payment terms based on the passage of time. Some lease agreements provide us with the option to renew the lease or purchase the leased property. Our future operating lease obligations would change if we exercised these renewal options and if we entered into additional operating lease arrangements.

(5)
On February 19, 2020, we completed an offering of $475 million in aggregate principal amount of our Senior Notes due February 15, 2028. The Senior Notes bear interest at a rate of 7.25% per year, with interest payable on February 15 and August 15 of each year. On August 1, 2025, we issued a notice of redemption for a portion of our Senior Notes. See Notes 7 and 13 of Notes to Condensed Consolidated Financial Statements (Unaudited) for more information.

(6)
On July 9, 2020, we entered into a note purchase agreement pursuant to which we issued our IQ Notes for CAD $50 million (approximately USD $36.8 million at the time of the transaction) in aggregate principal amount. The IQ Notes bear interest on amounts outstanding at a rate of 6.515% per year, payable on January 9 and July 9 of each year. See Note 7 of Notes to Condensed Consolidated Financial Statements (Unaudited) for more information. The IQ Notes were fully repaid on July 9, 2025.

We record liabilities for costs associated with mine closure, reclamation of land and other environmental matters. At June 30, 2025, our liabilities for these matters totaled $128.2 million. Future expenditures related to closure, reclamation and environmental expenditures at our sites are difficult to estimate, although we anticipate we will incur expenditures relating to these obligations over the next 30 years. For additional information relating to our environmental obligations, see Note 11 of Notes to Condensed Consolidated Financial Statements (Unaudited).

Critical Accounting Estimates

There have been no significant changes to the critical accounting estimates disclosed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2024 Form 10-K.

Off-Balance Sheet Arrangements

At June 30, 2025, we had no existing off-balance sheet arrangements, as defined under SEC regulations, that have or are reasonably likely to have a current or future effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

Guarantor Subsidiaries

Presented below are Hecla’s unaudited interim condensed consolidating financial statements as required by Rule 3-10 of Regulation S-X of the Securities Exchange Act of 1934, as amended, resulting from the guarantees by certain of Hecla's subsidiaries of the Senior Notes and IQ Notes (see Note 7 of Notes to Condensed Consolidated Financial Statements (Unaudited) for more information). The Guarantors consist of the following of Hecla's 100%-owned subsidiaries: Hecla Limited; Silver Hunter Mining Company; Rio Grande Silver, Inc.; Hecla MC Subsidiary, LLC; Hecla Silver Valley, Inc.; Burke Trading, Inc.; Hecla Montana, Inc.; Revett Silver Company; RC Resources, Inc.; Troy Mine Inc.; Revett Exploration, Inc.; Revett Holdings, Inc.; Mines Management, Inc.; Newhi, Inc.; Montanore Minerals Corp.; Hecla Alaska LLC; Hecla Greens Creek Mining Company; Hecla Admiralty Company; Hecla Juneau Mining Company; Klondex Holdings Inc.; Klondex Gold & Silver Mining Co.; Klondex Midas Holdings Limited; Klondex Aurora Mine Inc.; Klondex Hollister Mine Inc.; Hecla Quebec, Inc.; and Alexco Resource Corp. We completed the offering of the Senior Notes on February 19, 2020 under our shelf registration statement previously filed with the SEC. We issued the IQ Notes in four equal tranches between July and October 2020.

The unaudited interim condensed consolidating financial statements below have been prepared from our financial information on the same basis of accounting as the unaudited interim condensed consolidated financial statements set forth elsewhere in this report. Investments in the subsidiaries are accounted for under the equity method. Accordingly, the entries necessary to consolidate Hecla, the Guarantors, and our non-guarantor subsidiaries are reflected in the intercompany eliminations column. In the course of preparing consolidated financial statements, we eliminate the effects of various transactions conducted between Hecla and its subsidiaries and among the subsidiaries. While valid at an individual subsidiary level, such activities are eliminated in consolidation because, when taken as a whole, they do not represent business activity with third-party customers, vendors, and other parties. Examples of such eliminations include the following:

•
Investments in subsidiaries. The acquisition of a company results in an investment in debt or equity capital on the records of the parent company and a contribution to debt or equity capital on the records of the subsidiary. Such investments and capital contributions are eliminated in consolidation.
•
Capital contributions. Certain of Hecla's subsidiaries do not generate cash flow, either at all or that is sufficient to meet their capital needs, and their cash requirements are routinely met with inter-company advances from their parent companies. Generally on an annual basis, when not otherwise intended as debt, the Boards of Directors of such parent companies declare contributions of capital to their subsidiary companies, which increase the parents' investment and the subsidiaries' additional paid-in capital. Occasionally, parent companies may also subscribe for additional common shares of their subsidiaries. In consolidation, investments in subsidiaries and related additional paid-in capital are eliminated.
•
Debt. At times, inter-company debt agreements have been established between certain of Hecla's subsidiaries and their parents. The related debt liability and receivable balances, accrued interest expense (if any) and income activity (if any), and payments of principal and accrued interest amounts (if any) by the subsidiary companies to their parents are eliminated in consolidation.
•
Dividends. Certain of Hecla's subsidiaries which generate cash flow routinely provide cash to their parent companies through inter-company transfers. On at least an annual basis, the Boards of Directors of such subsidiary companies declare dividends to their parent companies, which reduces the subsidiaries' retained earnings and increases the parents' dividend income. In consolidation, such activity is eliminated.
•
Deferred taxes. Our ability to realize deferred tax assets and liabilities is considered for two consolidated tax groups of subsidiaries within the United States: The Nevada U.S. Group and the Hecla U.S. Group. Within each tax group, all subsidiaries' estimated future taxable income contributes to the ability of their tax group to realize all such assets and liabilities. However, when Hecla's subsidiaries are viewed independently, we use the separate return method to assess the realizability of each subsidiary's deferred tax assets and whether a valuation allowance is required against such deferred tax assets. In some instances, a parent company or subsidiary may possess deferred tax assets whose realization depends on the future taxable incomes of other subsidiaries on a consolidated-return basis, but would not be considered realizable if such parent or subsidiary filed on a separate stand-alone basis. In such a situation, a valuation allowance is assessed on that subsidiary's deferred tax assets, with the resulting adjustment reported in the eliminations column of the guarantor and parent's financial statements, as is the case in the unaudited interim financial statements set forth below. The separate return method can result in significant eliminations of deferred tax assets and liabilities and related income tax provisions and benefits. Non-current deferred tax asset

56

balances are included in other non-current assets on the consolidating balance sheets and make up a large portion of that item, particularly for the guarantor balances.

Separate financial statements of the Guarantors are not presented because the guarantees by the Guarantors are joint and several and full and unconditional, except for certain customary release provisions, including: (1) the sale or disposal of all or substantially all of the assets of the Guarantor; (2) the sale or other disposition of the capital stock of the Guarantor; (3) the Guarantor is designated as an unrestricted entity in accordance with the applicable provisions of the indenture; (4) Hecla ceases to be a borrower as defined in the indenture; and (5) upon legal or covenant defeasance or satisfaction and discharge of the indenture.

Item 3. Qua ntitative and Qualitative Disclosures About Market Risk

The following discussion about our exposure to market risks and risk management activities includes forward-looking statements that involve risks and uncertainties, as well as summarizes the financial instruments held by us at June 30, 2025, which are sensitive to changes in commodity prices and foreign exchange rates and are not held for trading purposes. Actual results could differ materially from those projected in the forward-looking statements. In the normal course of business, we also face risks that are either non-financial or non-quantifiable (See Part I, Item 1A. – Risk Factors of our 2024 Form 10-K).

Metals Prices

Changes in the market prices of silver, gold, lead, zinc and copper can significantly affect our profitability and cash flow. Metals prices can and often do fluctuate widely and are affected by numerous factors beyond our control (see Item 1A – Risk Factors – A substantial or extended decline in metals prices would have a material adverse effect on us in our 2024 Form 10-K). We utilize collars and financially-settled forward and put option contracts to manage our exposure to changes in prices for silver, gold, zinc and lead.

Provisional Sales

Sales of all metals products sold directly to customers, including by-product metals, are recorded as revenues when all performance obligations have been completed and the transaction price can be determined or reasonably estimated. For concentrate sales, revenues are generally recorded at the time of shipment at forward prices for the estimated month of settlement. Due to the time elapsed between shipment to the customer and the final settlement with the customer, we must estimate the prices at which sales of our metals will be settled. Previously recorded sales are adjusted to estimated settlement metals prices until final settlement by the customer. Changes in metals prices between shipment and final settlement will result in changes to revenues previously recorded upon shipment. Metals prices can and often do fluctuate widely and are affected by numerous factors beyond our control (see Item 1A – Risk Factors – A substantial or extended decline in metals prices would have a material adverse effect on us in our 2024 Form 10-K). At June 30, 2025, metals contained in concentrate sales and exposed to future price changes totaled 0.9 million ounces of silver, 750 ounces of gold, 9,475 tons of zinc and 4,825 tons of lead. If the price for each metal were to change by 10%, the change in the total value of the concentrates sold would be approximately $7.3 million. As discussed in Note 8 of Notes to Condensed Consolidated Financial Statements (Unaudited), we utilize a program designed and intended to mitigate the risk of negative price adjustments with limited mark-to-market financially-settled forward contracts for our silver, gold, zinc, lead and copper sales.

Commodity-Price Risk Management

See Note 8 of Notes to Condensed Consolidated Financial Statements (Unaudited) for a description of our commodity-price risk management program.

Foreign Currency Risk Management

We operate and have mining interests in Canada, which exposes us to risks associated with fluctuations in the exchange rates between the USD and the CAD. We determined the functional currency for our Canadian operations is the USD. As such, foreign exchange gains and losses associated with the re-measurement of monetary assets and liabilities from CAD to USD are recorded to earnings each period. For the three and six months ended June 30, 2025, we recognized a net foreign exchange loss of $3.5 million and $3.9 million, compared to a net foreign exchange gain of $2.7 million and $6.7 million for the three and six months ended June 30, 2024. Foreign currency exchange rates are influenced by a number of factors beyond our control. A 10% change in the exchange rate between the USD and CAD from the rate at June 30, 2025 would have resulted in a change of approximately $7.2 million in our net foreign exchange gain or loss. We do not hedge the remeasurement of monetary assets and liabilities. We do hedge some of our operating and capital costs denominated in CAD.

See Note 9 of Notes to Condensed Consolidated Financial Statements (Unaudited) for a description of our foreign currency risk management program.

Item 4. Con trols and Procedures

An evaluation was performed under the supervision and with the participation of our management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of our disclosure controls and procedures as required by Securities Exchange Act Rules 13a-15(e) and 15d-15(e) as of the end of the period covered by this report. Based on that evaluation, our CEO and CFO concluded that our disclosure controls and procedures, including controls and procedures designed to ensure that information required to be disclosed by us is accumulated and communicated to our management (including our CEO and CFO), were effective as of June 30, 2025, in assuring them in a timely manner that material information required to be disclosed in this report has been properly recorded, processed, summarized and reported. There were no changes in our internal control over financial reporting during the three months ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Internal control systems, no matter how well designed and operated, have inherent limitations. Therefore, even a system which is determined to be effective cannot provide absolute assurance that all control issues have been detected or prevented. Our systems of internal controls are designed to provide reasonable assurance with respect to financial statement preparation and presentation.

Item 1. Leg al Proceedings

For information concerning legal proceedings, refer to Note 11 of Notes to Condensed Consolidated Financial Statements (Unaudited), which is incorporated by reference into this Item 1.

Item 1A. Ris k Factors

Item 1A. – Risk Factors of our 2024 Form 10-K set forth information relating to important risks and uncertainties that could materially adversely affect our business, financial condition or operating results.

Tariffs, other import/export regulations, or trade disputes between the United States and other jurisdictions may have a negative effect on global economic conditions and on our business, financial results and financial condition.

There remains risk and uncertainty to our business and the global economy surrounding tariffs imposed by the Trump Administration and possible reciprocal tariffs announced by other countries. On July 6, 2025, Treasury Secretary Scott Bessent announced that countries that have not reached trade deals with the United States by August 1 will no longer be subject to a pause of the country-specific tariff rates previously announced on April 2. In addition, on July 7, the administration sent letters setting country-specific tariff rates for several countries with whom the U.S. has not reached trade deals, including Japan and South Korea, with tariffs set for each at 25% on all goods effective August 1. On July 22 and July 31, Japan and South Korea, respectively, reached trade deals with the United States, reducing their export tariff rates to 15%. To date, neither nation has reciprocated with tariffs that impact our products sold therein.

Currently, we sell our products into Japan and South Korea, as well as Canada, and we have recently had sales into China. We have very little sales in the United States. As of the date of this report, neither Japan nor South Korea have announced plans to implement reciprocal tariffs on U.S. imports in response to the U.S.-announced tariffs. While the impacts of tariffs on us to date have been immaterial to the sales of our products, reciprocal tariffs could make it more expensive for us to export our products to affected countries, including Japan and South Korea. This creates risk for us that customers in those or other tariff-impacted countries will seek to renegotiate existing agreements with us, seek to shift some or all of their increased costs to us in future agreements, break or terminate agreements with us if they are deemed uneconomic to the customer, or take other actions, any of which alone or in combination could materially adversely impact our business, financial condition, and results of operations. Further, any materials that we import to the U.S. from countries subject to tariffs could become more expensive if subject to a tariff, which could also have a material adverse impact on our business, financial condition, and results of operations.

In addition to possible impacts directly on our business, tariffs or other trade obstacles could have a material adverse effect on global economic conditions and the stability of global financial markets, and they may significantly reduce global trade. Any of these factors could depress economic activity, impact U.S. dollar/foreign currency exchange rates, restrict our access to customers and have a material adverse effect on our business, financial condition and results of operations.

Item 4. Mi ne Safety Disclosures

The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in exhibit 95 to this Quarterly Report.

Item 5. O ther Information

During the three months ended June 30, 2025, no director or officer of the Company adopted or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.
