Such risks are not exhaustive. New risk factors emerge from time to time, and it is not possible to predict all such risk factors, nor can we assess the impact of all such risk factors on our business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. Forward-looking statements are not guarantees of performance. You should not put undue reliance on these statements, which speak only as of the date hereof. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the foregoing cautionary statements.

1.Nature of Operations

TMC the metals company Inc. (“TMC” or the “Company”) was incorporated as a Cayman Islands exempted company limited by shares on December 18, 2019, and continued as a corporation under the laws of the province of British Columbia, Canada on September 9, 2021. The Company’s corporate office, registered address and records office is located at 10th floor, 1111 West Hastings Street, 15th Floor, Vancouver, British Columbia, Canada, V6E 2J3. The Company’s common shares and warrants to purchase common shares are listed for trading on the Nasdaq Global Select Market (“Nasdaq”) under tickers “TMC” and “TMCWW”, respectively.

The Company is a deep-sea minerals exploration company focused on the collection and processing of polymetallic nodules found on the seafloor in international waters of the Clarion Clipperton Zone in the Pacific Ocean (“CCZ”), with NORI Area D located approximately 1,500 miles southwest of San Diego, California. These nodules contain high grades of four metals (nickel, copper, cobalt, manganese) which can be used as (i) feedstock for battery cathode precursors (nickel, cobalt and manganese sulfates, or intermediate nickel-copper-cobalt matte or nickel-copper-cobalt alloy) for nickel-rich lithium-ion batteries, (ii) copper cathode for electric wiring, energy transmission and other applications and (iii) manganese silicate for manganese alloy production required for steel manufacturing.

On April 28, 2025, the Company’s wholly owned subsidiary, The Metals Company USA, LLC (“TMC USA”), formally submitted applications for two exploration licenses and one commercial recovery permit to the National Oceanic and Atmospheric Administration (“NOAA”) pursuant to the Deep Seabed Hard Mineral Resources Act of 1980 or DSHMRA. The submitted exploration license applications are to secure exploration rights over two areas in the CCZ, namely TMC USA-A and TMC USA-B, covering a total area of 199,895 square kilometers. The submitted commercial recovery permit application is to secure exploitation rights for a subset of the TMC USA-A area covering over 25,160 square kilometers. The commercial recovery application is the first submission under DSHMRA for commercial recovery of polymetallic nodules.

Both Nauru Ocean Resources Inc. (NORI) and Tonga Offshore Mining Limited (TOML) continue to hold their exploration licenses granted by the International Seabed Authority (ISA) and continue pursuing their efforts under these licenses.

The realization of the Company’s assets and attainment of profitable operations is dependent upon many factors including, among other things: financing being arranged by the Company to continue the scaling of the nodule collection system for the recovery of polymetallic nodules from the seafloor and the processing technology for the treatment of polymetallic nodules at commercial scale, the establishment of mineable reserves, the commercial and technical feasibility of seafloor polymetallic nodule collection and processing, metal prices, and regulatory approvals and environmental permitting for commercial operations. The outcome of these matters cannot presently be determined because they are contingent on future events and may not be fully under the Company’s control.

2.Basis of Presentation

These unaudited condensed consolidated interim financial statements are prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) for interim financial statements. Accordingly, certain information and footnote disclosures required by U.S. GAAP have been condensed or omitted in these unaudited condensed consolidated interim financial statements pursuant to such rules and regulation. In management’s opinion, these unaudited condensed consolidated interim financial statements include all adjustments of a normal recurring nature necessary for the fair presentation of the Company’s statement of financial position, operating results for the periods presented, comprehensive loss, shareholder’s equity and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be expected for the full year ending December 31, 2025 or for any other period. These unaudited condensed consolidated interim financial statements should be read in conjunction with the audited annual consolidated financial statements for the year ended December 31, 2024. The Company has applied the same accounting policies as in the prior year.

3.Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and the notes thereto. Significant estimates and assumptions reflected in these condensed consolidated interim financial statements include, but are not limited to, the evaluation of going concern, the valuation of share-based payments, including valuation of stock options (Note 13), valuation of warrants (Note 12), the valuation of the Royalty liability (Note 7) and the valuation of leases (Note 6). Actual results could differ materially from those estimates.

4.Fair Value of Financial Instruments

Fair value estimates of financial instruments are made at a specific point in time, based on relevant information about financial markets and specific financial instruments. As these estimates are subjective in nature, involving uncertainties and matters of significant judgment, they cannot be determined with precision. Changes in assumptions can significantly affect estimated fair value.

The Company measures fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the reporting date. In accordance with US GAAP, the Company utilizes a three-tier hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

| ● | Level 1- Valuations based on quoted prices in active markets for identical assets or liabilities that an entity has the ability to access.

| ● | Level 2- Valuations based on quoted prices for similar assets or liabilities, quoted prices for identical assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.

| ● | Level 3- Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

There were no transfers between fair value measurement levels during the three and six months ended June 30, 2025, and 2024.

As at June 30, 2025, and December 31, 2024, the carrying values of cash, receivables, short-term debt, accounts payable and accrued liabilities approximate their fair values due to the short-term nature of these instruments. The financial instruments also include royalty liability, accrued liabilities and warrants which are recorded at fair value as disclosed in Note 7, Note 9 and Note 12, respectively.

5.Recent Accounting Pronouncements Issued and Adopted

There were no recent accounting pronouncements issued and adopted by the Company during the period.

2023 Credit Facility and Loan Agreements with Company Related to Allseas

On March 22, 2023, the Company entered into an Unsecured Credit Facility Agreement, which was amended on July 31, 2023 (“2023 Credit Facility”), with Argentum Cedit Virtuti GCV (the “Lender”), the parent of Allseas Investments S.A. (“Allseas Investments”) and an affiliate of Allseas, pursuant to which, the Company may borrow from the Lender up to $25 million in the aggregate, from time to time, subject to certain conditions. All amounts drawn under the 2023 Credit Facility will bear interest based on the 6-month Secured Overnight Financing Rate, 180-day average plus a margin of 4.0% per annum payable in cash semi-annually (or plus a margin of 5% if paid-in-kind at maturity, at the Company’s election) on the first business day of each of June and January. The Company will pay an underutilization fee equal to 4.0% per annum payable semi-annually for any amounts that remain undrawn under the 2023 Credit Facility. The Company has the right to pre-pay the entire amount outstanding under the 2023 Credit Facility at any time before the 2023 Credit Facility’s maturity. The Company has the ability to settle certain charges under the 2023 Credit Facility in cash or in equity at the discretion of the Company. The 2023 Credit Facility also contains customary events of default. On March 24, 2025, the Company entered into a Letter Agreement with the Lender, pursuant to which the undrawn, unsecured credit facility was cancelled with the only obligation being the underutilization fees amounting to $2 million as payable.

On September 9, 2024, the Company entered into a working capital loan agreement (the “Working Capital Loan Agreement”) with Allseas Investments, a company related to Allseas. In accordance with the Working Capital Loan Agreement, Allseas Investments provided a loan to the Company of $7.5 million (the “Working Capital Loan”) to be used towards general corporate purposes and for the repayment of all outstanding amounts under the Short-Term Loan between the Company and the Lender. The Working Capital Loan is payable to Allseas Investments on or before the earlier of (i) the occurrence of certain financing events and (ii) April 1, 2025 (the “Repayment Date”). The Working Capital Loan will bear interest based on the 6-month Secured Overnight Financing Rate, 180-day average plus a margin of 4.0% per annum and is payable in two installments on January 2, 2025, and the Repayment Date (or plus a margin of 5.0% if all interest payments are deferred to the Repayment Date, at the Company’s election). On March 24, 2025, the Company entered into a Letter Agreement with Allseas Investments, pursuant to which the Repayment Date under the Working Capital Loan Agreement was extended to September 30, 2025, with principal and interest being repayable on that date. During the three and six months ended June 30, 2025, the Company incurred $0.1 million and $0.2 million, respectively as interest expense. During the second quarter of 2025, the Company repaid the entire outstanding loan and interest, amounting to $7.5 million and $0.5 million, respectively, thereby cancelling the Working Capital Loan Agreement.

In the second quarter of 2025, the entire gross proceeds from Allseas were received and the corresponding shares were issued.

As at June 30, 2025, the total amount payable to Allseas and its affiliates was $32.4 million, with the entire balance recorded in accrued liabilities in the Condensed Consolidated Balance Sheet (Note 9) (December 31, 2024: $33.3 million of which $25.8 recorded as accrued liabilities and $7.5 million recorded as short-term debt). As at June 30, 2025, Allseas and its affiliates owned 56.1 million TMC common shares (2024: 53.8 million TMC common shares) which constituted 14.1% (December 31, 2024: 15.8%) of total common shares outstanding.

​

7.Investment in Low Carbon Royalties

On February 21, 2023 (the “Closing Date”), the Company and its wholly-owned subsidiary, NORI, entered into an investment agreement (the “Royalty Agreement”) with Low Carbon Royalties Inc. (“Low Carbon Royalties”). In connection with the Royalty Agreement, NORI contributed a 2% gross overriding royalty (the “NORI Royalty”) on the Company’s NORI project area in the CCZ to Low Carbon Royalties. In consideration of the NORI Royalty, TMC received an ownership in Low Carbon Royalties and $5 million in cash, as of the Closing Date. In connection with the Royalty Agreement the Company entered into an Investor Rights Agreement with Low Carbon Royalties and a shareholder of Low Carbon Royalties, pursuant to which the Company and this shareholder each have a right, subject to certain percentage maintenance, to nominate a director to Low Carbon Royalties’ board of directors, along with registration and information rights.

​

The NORI Royalty was recorded as a royalty liability in the consolidated Balance Sheet in accordance with ASC 470, Debt (“ASC 470”). The Company elected to account for the royalty liability at fair value through profit and loss. The fair value was determined using a market approach which entails examining recent royalty transactions prior to the reporting date, focusing on those transactions that involve similar metals as contained in NORI’s polymetallic nodules. The Company compares the specific characteristics of these transactions to estimate the fair value. The fair value of the royalty liability as at June 30, 2025, remained unchanged at $14 million.

The Private Warrants were valued using a Black-Scholes model, which resulted in a Level 3 fair value measurement. The primary unobservable input utilized in determining the fair value of the Private Warrants was the expected volatility of the Company’s common shares. The expected volatility was estimated using a binomial model that assigned equal weight to the implied volatility of the Company’s Public Warrants, adjusted for the call feature triggered at prices above $18.00 over 20 trading days within any 30-day period, and the historical volatility of the common share price.

As at June 30, 2025, the fair value of outstanding Private Warrants of approximately $17.6 million is recorded as warrants liability. The following table presents the changes in the fair value of warrants liability:

​

​ | ​ | ​ | ​
​ |  | Private
​ | ​ | Warrants
Warrants liability as at December 31, 2024 | ​ | $ | 912
Increase in fair value of warrants liability | ​ |  | 16,670
Warrants liability as at June 30, 2025 | ​ | $ | 17,582

​

As at June 30, 2025, the fair value of the Private Warrants was estimated using the following assumptions:

On June 17, 2025, the Company waived the limitation set forth in the Class B Warrants with respect to the cashless exercise thereof so that the holders of the Class B Warrants may now exercise the Class B Warrants through a cashless exercise, whether or not a registration statement registering the issuance of the common shares underlying the Class B Warrants under the Securities Act of 1933, as amended, is then effective or available. As a result of the waiver, each Class B Warrant may now be immediately exercised by way of a cashless exercise, meaning that the holder may elect to not pay a cash purchase price upon exercise and instead receive upon such exercise the net number of common shares determined according to the formula set forth in the Class B Warrants, subject to the other terms and conditions of the Class B Warrants.

As at June 30, 2025, the value of outstanding of 3,615,000 Class B Warrants amounting to $3.4 million was recorded in additional paid in capital.

The fair value of the Nauru Warrants was calculated using a Black-Scholes valuation on May 30, 2025, resulting with a fair value of $3.6 per warrant. The fair value of the Nauru Warrants was estimated using the following assumptions:

​

​ | ​ | ​ | ​ | ​
​ |  | May 30, | ​
​ | ​ | 2025 | ​
Exercise price | ​ | $ | 4.72 | ​
Share price | ​ | $ | 4.47 | ​

The Nauru Warrants cannot be exercised until the following conditions have been met:

| ● | A subsidiary of the Company other than NORI obtains a permit, license or other authorization from the US for the conduct of deep seabed mineral activities; and

| ● | The subsidiary other than NORI commences commercial recovery activities of deep seabed minerals pursuant to that permit, license or other authorization.

The Nauru Warrants were not determined to be liabilities under ASC 480 as they were not mandatorily redeemable. The Company classified the Nauru Warrants as equity (per ASC 815), as the warrants require physical settlement and were also considered to be indexed to the Company’s share, wherein, upon exercise, a fixed number of common shares would be issued on payment of a fixed exercise price. As at June 30, 2025, the Company recorded the fair value of the Nauru Warrants amounting to $33.1 million as additional paid in capital. Since the Company receives no form of consideration from the Republic in return for issuing the Nauru Warrants, the entire fair value of the Nauru warrants amounting to $33.1 million is recorded as an expense under Nauru Warrant Cost in the Condensed Consolidated Statements of Loss and Comprehensive Loss.

Employee Stock Purchase Plan

On May 31, 2022, TMC’s 2021 Employee Stock Purchase Plan (“ESPP”) was approved at the Company’s 2022 annual shareholders meeting. As at June 30, 2025, there were 14,395,117 total common shares reserved for issuance under the ESPP, of which 14,043,174 remain available for future issuance. This included 3,407,085 shares added to the ESPP in January 2025 pursuant to the ESPP’s automatic annual increase provision. Under the ESPP, the number of shares reserved for issuance is subject to an annual increase provision which provides that on the first day of each of the Company’s fiscal years starting in 2022, common shares equal to the lesser of (i) 1% percent of the common shares outstanding on the last day of the immediately preceding fiscal year, or (ii) such lesser number of shares as is determined by the board of directors will be added to the ESPP.

During the three and six months ended June 30, 2025, a total of $4 thousand, (three and six months ended June 30, 2024: $7 thousand and $15 thousand respectively) was recorded as exploration and evaluation expenses in the statement of loss and comprehensive loss as share-based compensation expense, representing the share price purchase discount offered by the Company.

14.Loss per Share

Basic loss per share is computed by dividing the loss by the weighted-average number of common shares of the Company outstanding during the period. Diluted loss per share is computed by giving effect to all common share equivalents of the Company, including outstanding stock options, RSUs, warrants, Special Shares and options to purchase Special Shares, to the extent these are dilutive. Basic and diluted loss per share was the same for each period presented as the inclusion of all common share equivalents would have been anti-dilutive.

Anti-dilutive equivalent common shares were as follows:

​

​ | ​ | ​ | ​ | ​
​ | ​ | Six months ended | ​ | Six months ended
​ | ​ | June 30, | ​ | June 30,
​ |  | 2025 |  | 2024
Outstanding options to purchase common shares | ​ | 27,923,325 |  | 28,028,062
Outstanding RSUs | ​ | 37,072,442 |  | 35,761,561
Outstanding shares under ESPP | ​ | 1,627 | ​ | 2,767
Outstanding warrants | ​ | 60,113,552 | ​ | 30,730,770
Outstanding Special Shares and options to purchase Special Shares | ​ | 136,011,413 | ​ | 136,239,964
Total anti-dilutive common equivalent shares | ​ | 261,122,359 |  | 230,763,124

16.Contingent Liabilities

On October 28, 2021, a shareholder filed a putative class action against the Company, one of the Company’s executives and a former director in federal district court for the Eastern District of New York, captioned Caper v. TMC The Metals Company Inc. F/K/A Sustainable Opportunities Acquisition Corp., Gerard Barron and Scott Leonard. The complaint alleges that all defendants violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder, and Messrs. Barron and Leonard violated Section 20(a) of the Exchange Act, by making false and/or misleading statements and/or failing to disclose information about the Company’s operations and prospects during the period from March 4, 2021 and October 5, 2021. On November 15, 2021, a second complaint containing substantially the same allegations was filed, captioned Tran v. TMC the Metals Company, Inc. These cases were consolidated. On March 6, 2022, a lead plaintiff was selected. An amended complaint was filed on May 12, 2022, reflecting substantially similar allegations, with the Plaintiff seeking to recover compensable damages caused by the alleged wrongdoings. The Company denies any allegations of wrongdoing and filed and served the plaintiff a motion to dismiss on July 12, 2022 and intend to defend against this lawsuit. On July 12, 2023, an oral hearing on the motion to dismiss was held. On July 9, 2025, the Court granted our motion to dismiss with prejudice, and the case was dismissed in its entirety. No appeal was filed and the matter is now considered closed.

On January 23, 2023, investors in the 2021 private placement from the Business Combination filed a lawsuit against the Company in the Commercial Division of New York Supreme Court, New York County, captioned Atalaya Special Purpose Investment Fund II LP et al. v. Sustainable Opportunities Acquisition Corp. n/k/a TMC The Metals Company Inc., Index No. 650449/2023 (N.Y. Sup. Ct.). The Company filed a motion to dismiss on March 31, 2023, after which the plaintiffs filed an amended complaint on June 5, 2023. The amended complaint alleges that the Company breached the representations and warranties in the plaintiffs’ private placement Subscription Agreements and breached the covenant of good faith and fair dealing. The Plaintiffs are seeking to recover compensable damages caused by the alleged wrongdoings. The Company denies any allegations of wrongdoing and filed a motion to dismiss the amended complaint on July 28, 2023. On December 7, 2023, the Court granted the Company’s motion to dismiss the claim for breach of the covenant of good faith and fair dealing and denied the Company’s motion to dismiss the breach of the Subscription Agreement claim. The Company filed a notice of appeal regarding the Court’s denial of our motion to dismiss the breach of the Subscription Agreement claim. The appeal was heard on November 8, 2024. The NY Appellate Division upheld the lower court’s ruling in December 2024, moving the case into the discovery phase. There is no assurance that the Company will be successful in our defense of this lawsuit or that insurance will be available or adequate to fund any settlement or judgment or the litigation costs of this action. Such losses or range of possible losses cannot be reliably estimated.

On November 8, 2024, a shareholder filed a putative class action against the Company and certain of its executives in federal district court for the Central District of California, captioned Lin v. TMC The Metals Company Inc., Gerard Barron, and Craig Shesky. The complaint alleges that all defendants violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder, and Messrs. Barron and Shesky violated Section 20(a) of the Exchange Act, by making false and/or misleading statements and/or failing to disclose information regarding the classification of the non-financial asset received from our partnership with Low Carbon Royalties Inc. and the derecognition of the capitalized exploration contract related to NORI. The alleged misstatements and omissions pertain to the Company’s initial classification of this non-financial asset as a gain on disposition (being a sale of future revenue) and subsequent reclassification thereof as a royalty liability (and re-capitalization of the exploration contract) and the restatement of our previously issued financial statements as a result thereof for the three months ended March 31, 2023, the six months ended June 30, 2023 and the nine months ended September 30, 2023 in March 2024. The complaint purports to represent a class of shareholders who acquired the Company’s securities between May 12, 2023, and March 25, 2024, and seeks to recover compensable damages caused by the alleged wrongdoings. On February 6, 2025, the Court appointed a lead plaintiff. An amended complaint was filed on March 6, 2025. Pursuant to court-approved scheduling, the Company filed a motion to dismiss on April 10, 2025. The lead plaintiff filed an opposition on May 15, 2025, and the Company filed a reply on June 5, 2025. On June 18, 2025, the Court granted the Company’s motion to dismiss in full but granted plaintiffs leave to amend. The plaintiffs filed a Second Amended Complaint on July 2, 2025. The Company’s motion to dismiss the Second Amended Complaint was filed on August 6, 2025, the plaintiff’s opposition is expected to be filed by September 9, 2025, and a reply is expected to be filed by September 23, 2025. The Company intends to continue defending against the lawsuit. There can be no assurance, however, that the Company will be successful in its defense, or that insurance will be available or adequate to fund any settlement or judgment or the litigation costs of this action. Due to the early stage of this litigation, such losses or range of possible losses cannot be reliably estimated.

Revised Sponsorship Agreement with Republic of Nauru

On May 29, 2025, NORI entered into a Revised Sponsorship Agreement with the Republic of Nauru which provides NORI with exclusive right to explore for polymetallic nodules in the ISA contract area, pursuant to its ISA Exploration Contract. The Republic of Nauru will continue to sponsor NORI’s seabed mineral activities in the area as per the terms of this Sponsorship Agreement. In exchange for the Republic of Nauru’s sponsorship, NORI will make cash payments (“Continuity Benefits”) to the Republic of Nauru for its continued sponsorship. The Continuity Benefits would only be payable if (i) a subsidiary of the Company other than NORI obtains a permit, license or other authorization from the US for the conduct of deep seabed mineral activities; (ii) and that Subsidiary commences commercial recovery activities of deep seabed minerals pursuant to that permit, license or other authorization (“Continuity Conditions”) and the range of the Continuity Benefits to the Republic of Nauru will be between $265 million and $515 million (undiscounted). In connection with the Revised Sponsorship Agreement, the Company entered into a Deed of Guarantee and Indemnity in favor of the Republic of Nauru under which the Company guarantees certain obligations of NORI and provides customary indemnities. As of June 30, 2025, the Continuity conditions are not probable but reasonably possible, and therefore the Company has not recorded any amount as Continuity Benefits.

19.Subsequent Events

On August 4, 2025, the Company announced the publication of two technical economic studies prepared in accordance with Subpart 1300 of Regulation S-K: a Pre-Feasibility Study (“PFS”) and an Initial Assessment (“IA”) relating to the Company’s polymetallic nodule projects in the Clarion Clipperton Zone of the Pacific Ocean. The PFS, which covers the NORI Area D, represents the first declaration of Mineral Reserves for a polymetallic nodule project. Concurrently, the Company published an IA evaluating the broader resource potential across the Company’s remaining NORI and TOML contract areas. Management will consider this filing in its next evaluation of the Royalty Liability at September 30, 2025, which may cause an increase in the liability and expense amounts in the Company’s financial statements.

On August 4, 2025, TOML entered into a Revised Sponsorship Agreement with the Kingdom of Tonga which provides TOML with exclusive right to explore for polymetallic nodules in the ISA contract area, pursuant to its ISA Exploration Contract. The Kingdom of Tonga will continue to sponsor TOML’s seabed mineral activities in the area as per the terms of this Sponsorship Agreement. In exchange for the Kingdom of Tonga’s sponsorship, TOML will make cash payments (“Continuity Benefits”) to the Kingdom of Tonga for its continued sponsorship. The Continuity Benefits would only be payable if (i) a subsidiary of the Company other than TOML obtains a permit, license or other authorization from the US for the conduct of deep seabed mineral activities; (ii) and that Subsidiary commences commercial recovery activities of deep seabed minerals pursuant to that permit, license or other authorization (“Continuity Conditions”). In connection with the Revised Sponsorship Agreement, the Company entered into a Deed of Guarantee and Indemnity in favor of the Kingdom of Tonga under which the Company guarantees certain obligations of TOML and provides customary indemnities.

The following discussion and analysis provide information which management believes is relevant to an assessment and understanding of our condensed consolidated results of operations and financial condition. The discussion should be read in conjunction with the unaudited condensed interim consolidated financial statements and notes thereto contained in this Quarterly Report on Form 10-Q and the consolidated financial statements and notes thereto for the year ended December 31, 2024 contained in our 2024 Annual Report on Form 10-K. This discussion contains forward looking statements and involves numerous risks and uncertainties, including, but not limited to, those described in “Risk Factors” in Item 1A of Part I of the 2024 Annual Report on Form 10-K, as updated and/or supplemented in subsequent filings with the SEC, including our Quarterly Report on Form 10-Q for the quarter ended March 31, 2025 and this Quarterly Report on Form 10-Q. Actual results may differ materially from those contained in any forward-looking statements. Unless the context otherwise requires, references to “we”, “us”, “our”, “TMC” and “the Company” are intended to mean the business and operations of TMC the metals company Inc. and its consolidated subsidiaries. The unaudited condensed consolidated interim financial statements for the three and six months ended June 30, 2025 and 2024, respectively, present the financial position and results of operations of TMC the metals company Inc. and its consolidated subsidiaries.

Overview

We are a deep-sea minerals exploration company focused on the collection, processing and refining of polymetallic nodules found on the seafloor in international waters of the CCZ, with NORI Area D located approximately1,500 miles south-west of San Diego, California. The CCZ is a geological submarine fracture zone of abyssal plains and other formations in the Eastern Pacific Ocean, with a length of around 7,240 kilometers (4,500 miles) that spans approximately 4,500,000 square kilometers (1,737,000 square miles). Polymetallic nodules are discrete rocks that sit unattached to the seafloor, occur in significant quantities in the CCZ and have high concentrations of nickel, copper, cobalt and manganese in a single rock.

These four metals contained in the polymetallic nodules are critical for energy, defense, manufacturing and infrastructure. Our resource definition work to date shows that nodules in our contract areas represent the world’s largest undeveloped resource of the four critical metals contained in nodules. If we are able to collect polymetallic nodules from the seafloor on a commercial scale, we plan to use such nodules to produce three types of metal products: (i) feedstock for battery cathode precursors (nickel, cobalt and manganese sulfates, or intermediate nickel-copper-cobalt matte or nickel-copper-cobalt alloy) for nickel-rich lithium-ion batteries, (ii) copper cathode for electric wiring, energy transmission and other applications and (iii) manganese silicate for manganese alloy production required for steel manufacturing. Our mission is to build a carefully managed shared stock of metal (a “metal commons”) that can be used, recovered and reused for generations to come. Significant quantities of newly mined metal are required because existing metal stocks are insufficient to meet rapidly rising demand.

We are now in the evaluation stage following release of the TMC USA-A Prefeasibility Study, Technical Report Summary on August 4, 2025 where the Company declared world first mining reserves for a seafloor polymetallic nodule project. We have not yet obtained an exploitation contract or a commercial recovery permit from any regulators. Additionally, we do not yet hold the environmental or other permits required to construct and operate commercial-scale polymetallic nodule processing and refining facilities on land.

The ISA, comprised of 170 countries and the European Union, established regulations over deep-sea mining activities of their nationals, pursuant to UNCLOS. The ISA has adopted exploration regulations and issued 19 polymetallic nodule exploration contracts but has been unable to adopt the final exploitation regulations, standards and guidelines despite initiating work in 2014. Almost 30 countries, including the United States, have not ratified UNCLOS and are not member states of the ISA. To regulate deep-sea mining activities of its citizens in the high seas, the United States adopted the Deep Seabed Hard Mineral Resources Act of 1980, a U.S. domestic statute administered by the U.S. Department of Commerce through the National Oceanic and Atmospheric Administration, or NOAA. NOAA implemented regulations for exploration licenses in 1981 and for commercial recovery permits in 1989.

We continue to be focused on advancing our commercial production strategy under the U.S.-based DSHMRA regime. In April 2025, our wholly owned subsidiary, The Metals Company USA, LLC, or TMC USA, submitted two exploration license applications (covering 187,017 square kilometers in the CCZ referred to as TMC USA-A and TMC USA-B) and one commercial recovery permit application (covering 25,160 square kilometers in the CCZ referred to as TMC USA-A_2) to NOAA. These applications are estimated to hold approximately 1.639 billion wet tonnes of measured, indicated and inferred mineral resources. Together, the resources are estimated to contain approximately 15.5 million tonnes of nickel, 12.8 million tonnes of copper, 2.0 million tonnes of cobalt, and 345 million tonnes of manganese.

These applications reflect our belief that DSHMRA provides a viable and robust regulatory path to commercial production, distinct from the ISA regime under UNCLOS, which has repeatedly delayed the adoption of the Mining Code. We welcomed the recent Executive Order signed by President Trump on April 24, 2025, titled “Unleashing America’s Offshore Critical Minerals and Resources”, which directs the Commerce Secretary to implement an expedited permitting process under DSHMRA. In addition to directing the International Development Finance Corporation, Export-Import Bank and Trade and Development Agency to identify tools to support this new industry, the Executive Order instructs the Departments of Defense and Energy to assess the use of the National Defense Stockpile for nodule-derived minerals and of entering into offtake agreements for the procurement of these minerals. In addition, these departments are also directed to review and revise domestic processing capabilities for seabed mineral resources.

At the same time as we pursue the U.S. pathway, we continue to preserve our rights under the ISA system. While the ISA does not have jurisdiction over activities conducted under the regulatory authority of the United States, we maintain two ISA exploration contracts in the CCZ, one held by our subsidiary Nauru Ocean Resources Inc., or NORI, sponsored by the Republic of Nauru (“Nauru”), and one held by Tonga Offshore Mining Limited, or TOML, sponsored by the Kingdom of Tonga (“Tonga”). The ISA has issued a total of 19 exploration contracts covering approximately 1.28 million square kilometers, 17 of which are located in the CCZ. Currently, we are increasingly focused on pursuing commercial production through the U.S. regulatory pathway under DSHMRA, following the April 2025 submission of TMC USA’s exploration license and commercial recovery permit applications to NOAA. We do not believe pursuing licenses and permits with NOAA under DSHMRA affects our ISA exploration contracts.

We have key strategic partnerships with (i) Allseas, a leading global offshore contractor, which developed and tested a pilot collection system, and is now working to modify it into the first commercial production system, (ii) Pacific Metals Co. Ltd. (“PAMCO”), an experienced Japanese ferronickel producer, which is responsible for pre-feasibility and feasibility studies on nodule processing, and (iii) Glencore International AG (“Glencore”) which holds offtake rights to 50% of the NORI nickel and copper production if produced from the our subsidiary DeepGreen Engineering Pte Ltd. (“DGE”) owned or controlled facility. In addition, we have worked with engineering firm Hatch Ltd. (Hatch) and consultants Kingston Process Metallurgy Inc. (KPM) to develop a near-zero solid waste flowsheet. The primary processing stages of the flowsheet from nodule to NiCuCo matte intermediate were demonstrated as part of our pilot plant program at FLSmidth and XPS’ (Glencore subsidiary) facilities. The matte refining stages have been tested at SGS facility in Lakefield Canada with positive results. The near-zero solid waste flowsheet provides a design that is expected to serve as the basis for our onshore processing facilities. We expect this partnership to progress to a definitive tolling agreement in 2025, subject to successful evaluation study outcomes and agreement to mutually acceptable commercial terms.

To reach our objective and initiate commercial production, we are working to: (i) define our resource and project economics, (ii) develop a commercial offshore nodule collection system, (iii) assess the environmental and social impacts of offshore nodule collection, and (iv) develop onshore technology to process collected polymetallic nodules into a manganese silicate product, and an intermediate nickel-copper-cobalt alloy or matte product and/or end-products like nickel and cobalt sulfates, and copper cathode.

Developments in the Second Quarter 2025

Below are some of the major developments that occurred in the second quarter of 2025:

TMC USA Submits Application for Commercial Recovery of Deep-Sea Minerals Under U.S. Seabed Mining Code

On April 29, 2025, we announced that TMC USA had submitted the first-ever application for a commercial recovery permit and two exploration licenses under the Deep Seabed Hard Mineral Resources Act of 1980 (DSHMRA), advancing the Company’s timeline ahead of its original June 27, 2025 ISA application target. The application area for the commercial recovery permit, TMC USA-A_2, covers a total combined area of 25,160 square kilometers in the CCZ which includes areas that contain the Company’s already indicated and measured resources. TMC USA also submitted two exploration license applications: TMC USA-A and TMC USA-B with a total combined area of 187,017 square kilometers. The Company believes the TMC USA-A and USA-B exploration areas contain SEC SK 1300-compliant resources of 1.635 billion wet tonnes of polymetallic nodules supported by existing issued technical report summaries, with an additional estimated 300 million tonnes of potential exploration upside. The resources are estimated to contain approximately 15.5 million tonnes of nickel, 12.8 million tonnes of copper, 2.0 million tonnes of cobalt, and 345 million tonnes of manganese.

TMC Welcomes U.S. Executive Order to Expedite Permitting and Evaluate Offtake of Critical Minerals from Nodules in the High Seas

On April 25, 2025, we welcomed an Executive Order signed by President Trump to create a robust domestic supply for critical minerals derived from seabed resources. The Executive Order, ‘Unleashing America’s Offshore Critical Minerals and Resources’, directs the Commerce Secretary to implement an expedited permitting process under the DSHMRA, a statute passed by Congress in 1980. In addition to directing the International Development Finance Corporation, Export-Import Bank and Trade and Development Agency to identify tools to support this new industry, the order instructs the Departments of Defense and Energy to assess the use of the National Defense Stockpile for nodule-derived minerals and entering into offtake agreements for the procurement of these minerals. These departments are also directed to review and revise domestic processing capabilities for seabed mineral resources and Defense Production Act authorities. The executive order also issued a directive for a joint assessment, led by the Secretaries of Commerce, State, Interior, and Energy in coordination with U.S. partners and allies, on the feasibility of an international seabed benefit-sharing mechanism.

NOAA Confirms Substantial Compliance for TMC USA’s Exploration License Applications

On May 29, 2025, the U.S. National Oceanic and Atmospheric Administration confirmed substantial compliance for TMC USA’s exploration license applications over the USA-A and USA-B exploration areas. The confirmation secures TMC USA’s priority over these areas, including its commercial recovery permit application.

TMC Announces Registered Direct Offering for $37 million

On May 12, 2025, we entered into a securities purchase agreement with certain new and existing investors, including an existing strategic investor, for the sale of an aggregate of 12,333,333 common shares (the “Shares”) and accompanying Class C warrants (the “Class C Warrants”), in a registered direct offering. The offering price was $3.00 per Share, resulting in gross proceeds of $37.0 million ($36.75 million after associated fees), with each Share including an accompanying Class C Warrant to purchase one common share. The Class C Warrants are exercisable immediately upon issuance at a price of $4.50 per share and expire three years from issuance. The Class C Warrants include customary anti-dilution protections and a repurchase feature, permitting the Company to repurchase the warrants for $0.0001 per Common Share underlying the Class C Warrants if the volume-weighted average price of the Company’s common shares exceeds $7.00 per share for each trading day in a consecutive 20-trading-day period.

TMC and Nauru Announce Updated Sponsorship Agreement for Nauru Ocean Resources Inc. (NORI)

On June 4, 2025, we and the Government of the Republic of Nauru jointly announced the signing of a revised Sponsorship Agreement (Agreement), updating the terms of the Agreement signed between the parties in 2017. The Agreement guarantees that the Republic of Nauru will continue to receive existing financial benefits, training and capacity building programs and in-country community and social programs it receives today, while ensuring that, in consideration for its continued sponsorship of Nauru Ocean Resources Inc (“NORI”), Nauru will receive continuity benefits upon the commencement of commercial production by any subsidiary of TMC, other than NORI, under the U.S. regulatory regime.

Strategic Investment from Korea Zinc — a World-Leader in Non-Ferrous Metal Refining and pCAM Technology

On June 16, 2025, we announced that Korea Zinc Company Ltd. (“Korea Zinc”), a world leader in non-ferrous metal refining and precursor Cathode Active Material (pCAM) technology, had agreed to make a strategic investment of approximately $85.2 million in us through the purchase of common shares and warrants in a private placement. Under the terms of the agreement, Korea Zinc purchased 19.6 million common shares at the last market closing price of $4.34 per share and received a three-year warrant to purchase 6.9 million common shares (0.35 warrant shares for every 1 initial common share for no additional consideration) with an exercise price of $7.00 per share, subject to call exercise provisions at our option should our common shares trade above $10.00 for 20 consecutive days. Upon closing on June 26, 2025, Korea Zinc became one of our largest strategic shareholders with ownership of approximately 5% of the Company’s outstanding common shares. As part of this investment, in July 2025, Yun B. Choi, the Chief Executive Officer of Korea Zinc became a non-voting observer to our board of directors.

Appointment of Michael Hess and Alex Spiro to our Board of Directors

On June 16, 2025, we announced the appointment of Michael Hess and Alex Spiro to our Board of Directors strengthening TMC’s Board as we execute on our U.S. strategy and accelerate progress toward commercial recovery of polymetallic nodules in international waters under the existing U.S. seabed mining code. Michael brings deep operational and investment experience in the U.S. energy sector, along with a strong network and strategic perspective that will support our path toward commercial operations under U.S. law. Alex adds significant legal and capital markets expertise, and his counsel is already proving valuable as we work closely with NOAA and engage with the new Administration to advance our application.

Developments Subsequent to June 30, 2025

Publication of Technical Reports Prepared under Subpart 1300 of Regulation S-K

On August 4, 2025, the Company announced the publication of two technical economic studies prepared in accordance with Subpart 1300 of Regulation S-K: (i) a pre-feasibility study included in the technical report entitled “S-K 1300 NORI Area D Technical Report”, dated August 4, 2025 (the “NORI TRS”), prepared by AMC Consultants Pty Ltd. and other qualified persons, and (ii) an initial assessment included in the technical report entitled “Technical Report Summary—Initial Assessment of TOML and NORI Properties, Clarion-Clipperton Zone”, dated August 4, 2025 (the “NORI AND TOML Initial Assessment”), prepared by AMC Consultants Pty Ltd. and other qualified persons relating to its polymetallic nodule projects in the Clarion Clipperton Zone of the Pacific Ocean. The NORI TRS covers NORI Area D where the Company is applying for an exploration license and commercial permit under DSHMRA and was filed as Exhibit 96.1 to the Company’s Current Report on Form 8-K filed with the SEC on August 4, 2025 (the “August Form 8-K”).

The NORI and TOML Initial Assessment covers the remaining NORI and TOML areas where the Company is applying for an exploration license under DSHMRA and was filed as Exhibit 96.2 to the August Form 8-K.

TMC and Tonga Announce Updated Sponsorship Agreement for Tonga Offshore Mining Ltd. (TOML)

On August 4, 2025, we and the Government of the Kingdom of Tonga jointly announced the signing of a revised Sponsorship Agreement (Agreement), updating the terms of the Agreement signed between the parties in 2021. The Agreement guarantees that the Kingdom of Tonga will continue to receive existing financial benefits, training and capacity building programs and in-country community and social programs it receives today, while ensuring that, in consideration for its continued sponsorship of Tonga Offshore Mining Limited (“TOML”), the Kingdom of Tonga will receive continuity benefits upon the commencement of commercial production by any subsidiary of TMC, other than TOML, under the U.S. regulatory regime.

NOAA Confirms Full Compliance of TMC USA’s Exploration License Applications

On August 11, 2025, TMC USA received notice of full compliance from NOAA on its exploration applications, and confirmation that TMC USA has priority right over both exploration areas. Both applications entered the certification stage in late July, which we expect to be approximately 100 days. The news follows earlier determinations of substantial compliance in May 2025, demonstrating a systematic regulatory process under DSHMRA as the Company targets a fourth quarter 2027 production start

Regulatory Updates

Regulation of Mining of Deep-Sea Polymetallic Nodules by the United States

The Deep Seabed Hard Mineral Resources Act

The Deep Seabed Hard Mineral Resources Act of 1980, or DSHMRA, establishes a domestic legal regime for U.S. citizens to explore for and commercially recover hard mineral resources from the seabed in areas beyond U.S. national jurisdiction. DSHMRA affirms that deep-sea mining is a lawful freedom of the high seas, subject to a duty of reasonable regard to the interests of other states in their exercise of those and other freedoms recognized by the general principles of international law, and provides a regulatory structure administered by NOAA, an agency under the U.S. Department of Commerce. NOAA’s implementing regulations detail the criteria and conditions for issuance of deep seabed exploration licenses and commercial recovery permits to U.S. citizens, including any individual, corporation, or other entity organized under the laws of a U.S. state or territory.

The purpose of DSHMRA is to promote the development of seabed minerals by U.S. citizens while ensuring environmental protection, avoidance of conflict with other high seas uses, and consistency with international law. Before any license or permit is issued, NOAA must determine that the proposed activities meet a series of statutory requirements, including that the activity: (i) will not unreasonably interfere with the lawful use of the high seas by other states; (ii) is consistent with U.S. foreign policy and international obligations; (iii) does not create a risk to international peace and security; (iv) is not expected to result in significant adverse environmental effects; and (v) does not pose undue risk to life or property at sea. These findings reflect NOAA’s mandate of advancing U.S. commercial interests in seabed minerals while minimizing environmental and diplomatic risk.

TMC’s wholly owned subsidiary, TMC USA, a US-registered company established in 2013, has submitted three applications to NOAA: two for exploration licenses and one for a commercial recovery permit.

33

​

Table of Contents

Exploration licenses under DSHMRA grant exclusive rights to conduct technical studies in a defined area and are issued for ten-year terms. Commercial recovery permits authorize full-scale extraction for a period of 20 years subject to extension and are subject to enhanced environmental and operational requirements. To date, NOAA has issued exploration licenses over four areas, of which two are active, however it has not issued any commercial recovery permits under DSHMRA as no U.S. citizen had applied for a commercial recovery permit prior to TMC USA.

TMC USA initiated pre-application consultations with NOAA in the first quarter of 2025 and, following those discussions, submitted its applications in April 2025. These are now under agency review. The NOAA review process includes a determination whether applications for exploration licenses are in full or substantial compliance with the applicable requirements under DSHMRA and its implementing regulations within 30 days of receipt and whether applications for a commercial recovery permit are complete within 60 days. NOAA has notified the Company that its exploration license applications are in substantial compliance with the applicable requirements. NOAA is then expected to proceed with a full review of the applications, including interagency consultation with other U.S. government departments (including the Department of State, the Department of Defense, and the Environmental Protection Agency), preparation of an Environmental Impact Statement, or EIS, under NEPA, and a public comment period. NOAA will determine whether to issue the requested licenses and permit, and if so, under what terms and conditions. All licenses and permits issued under DSHMRA are subject to oversight, periodic reporting, and potential suspension or revocation for noncompliance or unforeseen environmental harm.

In July 2025, NOAA issued proposed amendments to its regulations under DSHMRA (15 C.F.R. Parts 970 and 971), published as FR Doc. 2025-12513 (90 Fed. Reg. 29806). The proposed rule introduces a new consolidated application procedure under § 971.214, allowing applicants to submit a single application for both an exploration license and commercial recovery permit. The revisions also include updated electronic submission requirements, restructured environmental review protocols, revised fee schedules, and clarified procedures for interagency consultation and public disclosure. These changes are intended to modernize and streamline the DSHMRA permitting process. The proposed rule remains subject to public comment until September 5, 2025.

DSHMRA and its regulations do not include a statutory deadline for application review. However, the Executive Order signed by President Trump on April 24, 2025, directs the Commerce Secretary to implement an expedited permitting process under DSHMRA.

NOAA issued four exploration licenses in 1984 to U.S.-sponsored consortia for polymetallic nodule exploration in the CCZ. Two of these licenses (USA-1 and USA-4) remain active and are currently held by Lockheed Martin. These licenses have been renewed until 2027 in accordance with DSHMRA’s statutory provisions, which require NOAA to grant extensions if the licensee has substantially complied with license terms.

We believe NOAA has historically adopted a cautious and science-based regulatory posture under DSHMRA, coordinating with other U.S. federal agencies and supporting environmental studies to inform future decisions. In the 1980s and 1990s, the United States entered into reciprocal recognition arrangements with other nations with similar domestic seabed mining laws, helping avoid overlapping claims prior to the establishment of the ISA. Once the ISA became operational in the 1990s, most reciprocating states transitioned to the UNCLOS/ISA system. The United States, however, remains outside that framework. NOAA is not restricted under DSHMRA from issuing licenses or permits over areas that are also subject to ISA exploration or exploitation contracts.

In addition, DSHMRA requires that all mining vessels and at least one transport vessel are U.S. flagged. TMC USA will ensure all vessels contracted for commercial recovery comply with relevant laws pertaining to vessel standards and crew safety. DSHMRA also requires that recovered minerals be processed in the United States unless a waiver is granted, in which case the permittee is required to provide assurances that processed materials are returned to the United States. We are currently evaluating U.S.-based vessel and processing options to satisfy this requirement as well as working with Japan and South Korea-based supply chain to ensure processed materials can be returned to the United States in case the permit to process outside the United States is granted for an initial period. If necessary, we expect to seek a waiver based on the statutory criteria and applicable regulations.

We expect to become subject to additional U.S. laws and regulations as development progresses and are in the early stages of analyzing their applicability and potential impact on our operations.

Table of Contents

On May 28, 2025, the National Oceanic and Atmospheric Administration (NOAA) determined that TMC USA’s two exploration license applications were in substantial compliance and confirmed TMC USA has priority of right over both exploration application areas.

On July 27, 2025, TMC USA submitted amended exploration applications with additional information requested by NOAA. NOAA confirmed that both exploration license applications were fully compliant and it had begun its certification process.

Existing ISA Exploration Contracts

We currently hold exploration rights to certain polymetallic nodule areas in the CCZ through our subsidiaries NORI and TOML, sponsored by the Republic of Nauru and the Kingdom of Tonga, respectively.

NORI, our wholly-owned subsidiary, holds exploration rights to four blocks (NORI Area A, B, C, and D, the “NORI Contract Area”) covering 74,830 square kilometers in the CCZ that were granted by the ISA in July 2011. NORI is sponsored by Nauru pursuant to a certificate of sponsorship signed by the Government of Nauru on April 11, 2011. The D block of the NORI area (“NORI Area D”) is the seafloor parcel where we have performed the most resource definition and environmental work to date. NORI commissioned AMC Consulting Ltd (“AMC”), a leading mining consulting firm, to undertake an Initial Economic Assessment of the mineral resource contained in NORI Area D and to compile a technical report compliant with Canadian National Instrument (NI 43-101), which was completed in March 2021. AMC subsequently compiled the NORI Technical Report Summary, dated March 2021, which included an initial assessment and an economic analysis of NORI Area D prepared in accordance with the SEC’s Modernization of Property Disclosures for Mining Registrants set forth in subpart 1300 of Regulation S-K (the “SEC Mining Rules”).

TOML, our wholly-owned subsidiary which we acquired in March 2020, holds exploration rights to an area covering 74,713 square kilometers in the CCZ that were granted by the ISA in January 2012 (the “TOML Contract Area”). On March 8, 2008, Tonga and TOML entered into a sponsorship agreement formalizing certain obligations of the parties in relation to TOML’s exploration application to the ISA (subsequently granted) for the TOML Contract Area. The sponsorship agreement was updated on August 4, 2025. TOML commissioned a Technical Report Summary by AMC, dated March 2021.

Key Trends, Opportunities and Uncertainties

We are currently a pre-revenue company, and we do not anticipate earning revenues (other than potential service revenue) until one of our wholly-owned subsidiaries receives an exploitation contract or commercial recovery permit and we are able to successfully collect and process polymetallic nodules into saleable products on a commercial scale. We believe that our performance and future success pose risks and challenges, including those related to the approval of an application for a commercial recovery permit, development of environmental terms, conditions and restrictions associated with our application and development of our technologies to collect and process polymetallic nodules. These risks, as well as other risks, are discussed in the section entitled “Risk Factors” in Item 1A of Part I of the 2024 Annual Report on Form 10-K, as further updated and/or supplemented in subsequent filings with the SEC.

Basis of Presentation

We currently conduct our business through one operating segment. As a pre-revenue company with no commercial operations, our activities to date have been limited. Our results are reported under Generally Accepted Accounting Principles in the United States (“U.S. GAAP”) and in U.S. dollars.

Components of Results of Operations

We are an exploration-stage company with no revenue to date and a net loss of $74.3 million and $94.9 million for three and six months ended June 30, 2025, respectively, compared to a net loss of $20.2 million and $45.4 million in the same period of 2024, respectively. We have an accumulated deficit of approximately $726.4 million from inception through June 30, 2025.

​

Table of Contents

Our historical results may not be indicative of our future results for reasons that may be difficult to anticipate. Accordingly, the drivers of our future financial results, as well as the components of such results, may not be comparable to our historical or projected results of operations.

Revenue

To date, we have not generated any revenue. We expect to generate revenue once we receive a commercial recovery permit, and we are able to successfully collect and process polymetallic nodules into saleable products on a commercial scale. Any revenue from initial production is difficult to predict.

Exploration and Evaluation Expenses

We expense all costs relating to exploration and development of mineral claims. Such exploration and development costs include, but are not limited to, regulatory approvals, exploration mineral title management, geological, geochemical and geophysical studies, environmental baseline studies and process development activities. Our exploration expenses are impacted by the amount of exploration work conducted during each period. The acquisition cost of polymetallic nodule mineral title will be charged to operations as amortization expense on a unit-of-production method based on proven and probable reserves should commercial production commence in the future.

General and Administrative Expenses

General and administrative (“G&A”) expenses consist primarily of compensation for employees, consultants and directors, including share-based compensation, consulting fees, investor relations expenses, expenses related to advertising and marketing functions, insurance costs, office and sundry expenses, professional fees (including legal, audit and tax fees), travel expenses and transfer and filing fees.

Share-based compensation costs from the issuance of stock options and restricted share units (“RSUs”) are measured at the grant date based on the fair value of the award and are recognized over the related service period. Share-based compensation costs are charged to exploration expenses and general and administrative expenses depending on the function fulfilled by the holder of the award. In instances where an award is issued for financing related services, the costs are included within equity as part of the financing costs. We recognize forfeiture of any awards as they occur.

Nauru Warrant cost

The Nauru Warrant cost represents the fair value of the warrants issued as part of the revised sponsorship agreement with the Government of the Republic of Nauru signed on May 29, 2025. As the warrants did not contain complex features, the fair value was calculated using a Black-Scholes valuation model.

Interest Income

Interest income consists primarily of interest earned on our cash and cash equivalents.

Fees and Interest on Borrowings and Credit Facilities

Fees and interest on borrowings and credit facilities represent interest charged on the Company’s short-term debt and interest and underutilization fees associated with the Company’s credit facilities.

Foreign Exchange Gain/Loss

The foreign exchange gain or loss for the periods reported primarily relates to unrealized gain or loss due to revaluation of foreign denominated accounts payable and accrued liabilities.

Change in Fair Value of Warrants Liability

The change in fair value of warrants liability primarily consists of the change in the fair value of our 9,500,000 Private Warrants, which is re-measured at the end of each reporting period.

Results of Operations

The following is a discussion of our results of operations for the three and six months ended June 30, 2025 and 2024. Our accounting policies are described in Note 3 “Significant Accounting Policies” in our financial statements filed as part of the 2024 Annual Report on Form 10-K.

​

Three Months ended June 30, 2025 compared to Three Months ended June 30, 2024

We reported a net loss of approximately $74.3 million in the second quarter of 2025, compared to a net loss of $20.2 million in the same period of 2024. The following explains the major reasons for the increase in the net loss in the second quarter of 2025.

Exploration and Evaluation Expenses

Exploration and evaluation expenses for the three months ended June 30, 2025 were $10.5 million, compared to $12.4 million for the same period in 2024. The decrease of $1.9 million is primarily due to a decrease in mining, technological and process development activities of $2.4 million compared to the same quarter of 2024, partially offset by an increase in share-based compensation of $0.2 million due to the amortization of the fair value of RSUs and options granted to officers in the second quarter of 2024.

General and Administrative Expenses

G&A expenses for the three months ended June 30, 2025 were $11.5 million compared to $7.9 million for the same period in 2024. The increase of $3.6 million in G&A expenses was mainly the result of an increase in share-based compensation of $1 million due to the amortization of the fair value of RSUs and options granted to the directors and officers in the second quarter of 2024, an increase of $2 million in consulting costs to pursue the U.S. regulatory route and financing activities.

Nauru Warrant cost

As part of the signing of a revised Sponsorship Agreement with the Government of the Republic of Nauru on May 29, 2025, we issued 9,146,268 warrants to the Republic to purchase common shares of the Company. The fair value of the Nauru Warrants, calculated using a Black-Scholes valuation model, valued each warrant at $3.62 for a total value of $33.1 million. For further details on this non-recurring item, refer to Note 12 in the Company’s second quarter 2025 interim financial statements.

Change in F air V alue of W arrants L iability

The increase in the fair value of the 9,500,000 Private Warrants liability in the three months ended June 30, 2025 of $16.2 million, results from the significant increase in the price of the Company’s shares and the price of our public warrants over this same period (284% and 568% respectively). Refer to Note 12 in the Company’s second quarter 2025 interim financial statements for further details on this non-operating, non-cash increase.

Fees and Interest on Borrowings and Credit Facilities

The interest charged on the Company’s short-term debt borrowings was $0.1 million in the second quarter of 2025 ($nil for the same period of 2024), while interest on drawn amounts on the Company’s credit facilities was $0.1 million and underutilization fees on these same facilities was $0.6 million in the second quarter of 2025 ($0.1 and $0.4 million over the same periods in 2024, respectively).

Six Months ended June 30, 2025 compared to Six Months ended June 30, 2024

We reported a net loss of $94.9 million in the first half of 2025, compared to a net loss of $45.4 million in the same period of 2024. The following explains the major reasons for the increase in the net loss in the first half of 2025.

Exploration and Evaluation Expenses

Exploration and evaluation expenses for the six months ended June 30, 2025 were $20.0 million, compared to $30.5 million for the same period in 2024. The decrease of $10.5 million was primarily due to an decrease of $11 million in mining, technological and process development cost and a decrease of $1.2 million incurred on environmental studies as the costs incurred in the first six months of 2024 were higher on account of transit costs of the Allseas vessel in the first quarter of 2024, transportation of nodules to PAMCO’s facility in Japan and due to Campaign 8 which was completed in the first quarter of 2024, offset by increase in share-based compensation of $1.2 million due to amortization of the fair value of RSUs and options granted to the officers in the second quarter of 2024.

General and Administrative Expenses

G&A expenses for the six months ended June 30, 2025 were $19.9 million, compared to $14.5 million for the same period in 2024. The increase of $5.4 million in G&A expenses in the first half of 2025 was mainly the result of an increase in share-based compensation of $3.2 million due to amortization of the fair value of RSUs and options granted to the directors and officers in the second quarter of 2024, an increase in consulting cost of $1.5 million to pursue the U.S. regulatory route, and higher cost incurred on legal, and advisory activities.

Nauru Warrant cost

As part of the signing of a revised Sponsorship Agreement with the Government of the Republic of Nauru on May 29, 2025, we issued 9,146,268 warrants to the Republic to purchase common shares of the Company. The fair value of the Nauru Warrants, calculated using a Black-Scholes valuation model, valued each warrant at $3.62 for a total value of $33.1 million. For further details on this non-recurring item, refer to Note 12 in the Company’s second quarter 2025 interim financial statements.

Change in F air V alue of W arrants L iability

The significant increase in the fair value of the 9,500,000 Private Warrants liability in the first half of 2025 of $16.7 million, results from the significant increase in the price of the Company’s shares and the price of our public warrants, mainly over the second quarter of 2025. Refer to Note 12 in the Company’s second quarter 2025 interim financial statements for further details on this non-operating, non-cash increase.

Liquidity and Capital Resources

​

Table of Contents

Our primary sources of financing have come from private placements and public offerings of Common Shares and warrants, the issuance of convertible debentures and from credit facilities. As of June 30, 2025, we had cash on hand of $115.8 million.

In light of the significant deficit in expected funding following the closing of the Business Combination in September 2021, we adopted what we call a “capital-light” strategy whereby we removed any allocation of funds to capital expenditures that were not deemed necessary to support the submission of an application for a commercial recovery permit contract for the TMC USA-A area, and by negotiating the settlement of program expenditures with our equity whenever possible.

We have yet to generate any revenue from our business operations. We are an exploration-stage company and the recovery of our investment in mineral exploration contracts and attainment of profitable operations is dependent upon many factors including, among other things, the development of commercial production system for collecting polymetallic nodules from the seafloor as well as the development of our processing technology for the metallurgical treatment of such nodules, the establishment of mineable reserves, the demonstration of commercial and technical feasibility of seafloor polymetallic nodule collection and processing systems, metal prices, and securing US exploration licenses and a commercial recovery permit and ISA exploitation contracts or provisional approvals. While we have obtained financing in the past, there is no assurance that such financing will continue to be available on favorable terms, in sufficient amounts, or at all.

We expect to incur significant expenses and operating losses for the foreseeable future, as we advance our application to NOAA for exploration licenses and a commercial recovery permit and preparation for potential commercialization.

Based on our current cash balance, when compared with our forecasted cash expenditures, we believe we will have sufficient funds to meet our obligations that become due within the next twelve months. Our estimates used in reaching this conclusion are based on information available as at the date of filing this Quarterly Report. Accordingly, actual results could differ from these estimates and resulting variances may result in our need for additional funding in an amount greater or earlier than expected, due to changes in business conditions or other developments, including, but not limited to, deferral of approvals, capital and operating cost escalation, currently unrecognized technical and development challenges, our ability to pay certain vendors or suppliers in our Common Shares or changes in external business environment.

In addition, we will however need and are seeking additional financing to fund our continued operations over time. These financings could include additional public or private equity, debt financings, equity-linked financings or other sources of financing, including through non-dilutive asset, royalty or project-based and/or asset-based financings. If these financing or other financing sources are not available, or if the terms of financing are less desirable than we expect, or if in insufficient amounts, we may be forced to delay our exploration and/or exploitation activities or further scale back our operations, which could have a material adverse impact on our business and financial prospects.

On September 16, 2022, we filed a registration statement on Form S-3 with the SEC, which the SEC declared effective on October 14, 2022, to sell up to $100 million of securities. In addition, on November 30, 2023, we filed an additional registration statement on Form S-3 with the SEC, which the SEC declared effective on December 8, 2023, to sell up to an additional $100 million of securities. Securities that may be sold under the registration statements include common shares, preferred shares, debt securities, warrants and units. Any such offering, if it does occur, may happen in one or more transactions. Specific terms of any securities to be sold under these registration statements will be described in supplemental filings with the SEC. As previously disclosed, the capacity under these registration statements is used as part of our capital raising strategy and we plan to file a new registration statement for the issuance of additional securities in the future.

On December 22, 2022, we entered into an At-the-Market Equity Distribution Agreement (the “Sales Agreement”) with Stifel, Nicolaus & Company, Incorporated (“Stifel”) and Wedbush Securities Inc., as sales agents, allowing us, from time to time, to issue and sell Common Shares with an aggregate offering price of up to $30 million. On December 21, 2023, we amended the Sales Agreement to remove Stifel as a sales agent. The offer and sales of the shares are made under our effective “shelf” registration statement on Form S-3 filed with the SEC on September 16, 2022, which the SEC declared effective on October 14, 2022. In 2024 we sold 3,251,590 Common Shares for gross proceeds of $4.9 million under this offering. In the three and six months ended June 30, 2025, we issued 4,567,770 and 7,542,996 common shares, respectively, at an average share price of $2.08 and $2.02, for net proceeds of $9.2 million and $14.8 million respectively.

All amounts drawn under the 2023 Credit Facility bore interest at the 6-month SOFR, 180-day average plus 4.0% per annum payable in cash semi-annually (or plus 5% if paid-in-kind at maturity, at our election) on the first business day of each of June and January. We agreed to pay an underutilization fee equal to 4.0% per annum payable semi-annually for any amounts that remain undrawn under the 2023 Credit Facility. We had the right to pre-pay the entire amount outstanding under the 2023 Credit Facility at any time, before the 2023 Credit Facility’s stated maturity of August 31, 2025. The 2023 Credit Facility also contained customary events of default. No amounts had been drawn under the 2023 Credit Facility. Pursuant to the Letter Agreement we entered into on March 24, 2025, we and Argentum Cedit Virtuti GCV agreed to cancel the 2023 Credit Facility with no outstanding amounts remaining, other than our obligation to pay the underutilization fee thereunder.

On August 14, 2023, we entered into a securities purchase agreement for a Registered Direct Offering of our Common Shares and Class A Warrants (the “2023 Offering”). The purchase price for each Common Share and Class A Warrant to purchase 0.5 Common Shares was $2.00 per unit. The exercise price to purchase one Common Share under the Class A Warrants is $3.00, subject to adjustment as provided in the warrant agreement. No investor elected to exercise its right to purchase additional Common Shares and accompanying Class A Warrants on or before September 15, 2023 under the terms of the securities purchase agreement. As of December 31, 2023, we had received gross proceeds of $15.9 million (approximately $14.6 million net of transaction fees) in the Registered Direct Offering. We received the remaining $9 million of gross proceeds on January 31, 2024, from an investor affiliated with us. As a result of the 2024 Purchase Agreement (as described below), the exercise price of the Class A Warrants was reset to $2.00 as the down round feature of the Class A Warrants agreement was triggered.

On August 13, 2024, we entered into the First Amendment to the 2024 Credit Facility to increase the borrowing limit to $25 million in the aggregate ($12.5 million from each of the 2024 Lenders). Under the terms of the First Amendment, the borrowing limit was due to return to the initial $20 million in the aggregate ($10 million from each of the 2024 Lenders) upon certain financing events.

We may receive up to approximately $437 million in aggregate gross proceeds from cash exercises of the Public Warrants, the Private Warrants, the Class A Warrants and the Class B Warrants, Class C Warrants, and Warrants issued to Korea Zinc and Republic of Nauru based on the per share exercise price of such warrants. However, the exercise price for the outstanding Public Warrants and Private Warrants is $11.50 per common share and there can be no assurance that such warrants will be in the money prior to their expiration, and as such, such warrants may expire worthless. Based on the current trading price of our Common Shares we do not expect to receive any proceeds from the exercise of the Public Warrants and Private Warrants unless there is a significant increase in the price of our Common Shares. In certain circumstances, the Public Warrants and Private Warrants may be exercised on a cashless basis and the proceeds from the exercise of such warrants will decrease. Furthermore, even if the warrants will be in the money, the holders of the warrants are not obligated to exercise their warrants, and we cannot predict whether holders of the warrants will choose to exercise all or any of their warrants. The warrants issued to the Republic of Nauru can only be exercised after the commercial recovery permit is received and commercial production commences and there can be no assurance that the exercise conditions will be met prior to their expiration. In addition, the exercise price to purchase one Common Share under the outstanding Class A Warrants and Class B Warrants is $2.00 each, Class C Warrants is $4.5, warrants issued to Korea Zinc is $7 and warrants issued to Republic of Nauru is $4.72 (subject to customary adjustments) and there can be no assurance that such warrants will be exercised prior to their expiration, and as such, such warrants may expire, and we will not receive any proceeds from the exercise thereof.

Contractual Obligations and Commitments

NORI Exploration Contract

As part of the NORI Exploration Contract with the ISA, NORI submitted a periodic review report to the ISA which included a five-year plan covering 2022 to 2026: NORI is currently implementing its approved five-year plan. The cost of the estimated work plan for 2025 onwards is dependent on NORI’s current five-year plan and any future approved exploration contract extension program of work. Work plans are reviewed annually by us, agreed with the ISA and may be subject to change depending on our progress to date. NORI’s exploration contract expires on July 21, 2026. NORI is required to submit an application for extension no later than six months before the expiration of the contract. NORI intends to submit an application for a five-year extension in early 2026.

TOML Exploration Contract

As part of the TOML Exploration Contract with the ISA, TOML submitted a periodic review report to the ISA which included a five-year plan covering 2022 to 2026: TOML is currently implementing its approved plan, which included an estimated five-year expenditure of up to $44 million. The five-year estimated expenditure is indicative and subject to change, TOML will review the program regularly and TOML will inform the ISA of any changes through its annual reports. TOML intends to submit an application for a five-year extension in 2026.

Regulatory Obligations Relating to Exploration Contracts

Under ISA requirements, both TOML and NORI require sponsorship from their host sponsoring nations, Tonga and Nauru, respectively. Each company has been registered and incorporated within the applicable host nation’s jurisdiction. The ISA requires that a contractor must obtain and maintain sponsorship by a host nation that is a member of the ISA, and such state must maintain effective supervision and regulatory control over such sponsored contractor. Each of TOML and NORI is subject to the registration and incorporation requirements of these nations. In the event the sponsorship is otherwise terminated, such subsidiary will be required to obtain new sponsorship from another state that is a member of the ISA. Failure to obtain such new sponsorship could have a material impact on the operations of such subsidiary and us.

Sponsorship Agreements

On July 5, 2017, Nauru, the Nauru Seabed Minerals Authority and NORI entered into the NORI Sponsorship Agreement formalizing certain obligations of the parties in relation to NORI’s exploration and potential exploitation of the NORI Area. NORI is required to pay an administration fee each year to Nauru for such administration and sponsorship, which is subject to review and increase in the event NORI is granted an ISA exploitation contract. On May 29, 2025, NORI and the Government of Nauru entered into an updated sponsorship agreement that superseded the 2017 agreement and reaffirms the Government of Nauru’s sponsorship of NORI under the ISA regime. Under the revised agreement, the Government of Nauru and NORI agreed to certain updated payment and taxation commitments, including NORI’s commitment to pay corporate income tax within Nauru assuming future NORI operations are ultimately profitable. NORI also committed to maintaining its in-country investments and presence.

On March 8, 2008, Tonga and TOML entered into the TOML Sponsorship Agreement formalizing certain obligations of the parties in relation to TOML’s exploration and potential exploitation of the TOML Area. On September 23, 2021, Tonga updated the TOML Sponsorship Agreement harmonizing the terms of its engagement with TOML with those held by NORI with Nauru. On August 4, 2025, TOML and the Government of Tonga entered into a further updated sponsorship agreement reaffirming the Government of Tonga’s sponsorship of TOML and formalizing certain revised terms of engagement. Under the updated agreement, TOML reaffirmed its commitment to pay corporate income tax within Tonga assuming future operations are ultimately profitable. TOML also committed to maintaining its in-country investments and presence.

Allseas Agreements

On March 29, 2019, we entered into a strategic alliance with Allseas to develop a system to collect, lift and transport nodules from the seafloor to shore and agreed to enter into a nodule collection and shipping agreement whereby Allseas would provide commercial services for the collection of the first 200 million metric tonnes of polymetallic nodules on a cost plus 50% profit basis. In furtherance of this agreement, on July 8, 2019, we entered into a Pilot Mining Test Agreement with Allseas (“PMTA”), which was amended on five occasions through February 2023, to develop and deploy a PMTS, successful completion of which is a prerequisite for our application for an exploitation contract with the ISA. Under the PMTA, Allseas agreed to cover the development cost of the project in exchange for a payment from us upon successful completion of the pilot trial of the PMTS in NORI Area D.

On March 16, 2022, NORI and Allseas entered into a non-binding term sheet for the development and operation of a commercial nodule collection system. The pilot nodule collection system developed and tested by Allseas is expected to be upgraded to a commercial system with an expanded targeted production capacity of up to an estimated 3.0 million tonnes of wet nodules per year, to be delivered in stepped increments. NORI and Allseas intend to equally finance all costs related to developing and getting the first commercial system into production. Once in production, NORI is expected to pay Allseas a nodule collection and transshipment fee and, as Allseas scales up production to up to an estimated 3.0 million wet tonnes of nodules per year, it is expected that unit costs will be reduced. Following the successful completion of the NORI Area D pilot collection system trials in November 2022 and subsequent analysis of pilot data, the parties are reviewing Project Zero Offshore Nodule Collection System production targets, system design and cost estimates and intend to enter into a binding Heads of Terms by the end of 2025. The parties expect to further detail their relationship in three separate definitive agreements for engineering, conversion/build and commercial operations phase, respectively. Subject to the necessary regulatory approvals, Allseas and NORI also intend to investigate acquiring a second production vessel similar to the Hidden Gem, another Samsung 10000, with the potential for an additional production rate of three million tonnes of wet nodules per year and lower associated per tonne production cost. There can be no assurances, however, that we will enter into definitive agreements with Allseas contemplated by the non-binding term sheet in a particular time period, or at all, or on terms similar to those set forth in the non-binding term sheet, or that if such definitive agreements are entered into by us that the proposed commercial systems and second production vessel will be successfully developed or operated in a particular time period, or at all.

The warrant vested and became exercisable on successful completion of the PMTS in November 2022.

On November 11, 2022, our board of directors approved the successful completion and testing of the PMTS in the NORI Area D and payment of the third milestone amounting to $10 million and additional costs owed to Allseas under the PMTA by issuing 10.85 million Common Shares to Allseas priced at $1.00 per share on February 23, 2023.

On August 1, 2023, we entered into an Exclusive Vessel Use Agreement with Allseas pursuant to which Allseas will give us exclusive use of the vessel (“Hidden Gem”) in support of the development of the Project Zero Offshore Nodule Collection System until the system is completed or December 31, 2026, whichever is earlier. In consideration of the exclusivity term, on August 14, 2023, we issued 4.15 million Common Shares to Allseas.

Offtake Agreement

On May 25, 2012, DGE and Glencore entered into a copper offtake agreement and a nickel offtake agreement. DGE has agreed to deliver to Glencore 50% of the annual quantity of copper and nickel produced by a DGE-owned facility from nodules derived from the NORI Area at London Metal Exchange referenced market pricing with allowances for product quality and delivery location. Either party may terminate the agreement upon a material breach or insolvency of the other party. Glencore may also terminate the agreement by giving twelve months’ notice.

In accordance with the Working Capital Loan Agreement, Allseas Investments provided a loan to us amounting to $5 million (the “Working Capital Loan”) on September 10, 2024, to be used towards general corporate purposes and the repayment of all outstanding amounts under the Short-Term Loan between us and the Lender. The Working Capital Loan is payable to the Lender on or before the earlier of (i) the occurrence of certain financing events and (ii) April 1, 2025 (the “Original Repayment Date”). The Working Capital Loan will bear interest based on the 6-month Secured Overnight Financing Rate, 180-day average plus a margin of 4.0% per annum and is payable in two installments on January 2, 2025, and the Original Repayment Date (or plus a margin of 5.0% if all interest payments are deferred to the Original Repayment Date, at our election). On October 18, 2024, we entered into the First Amendment to the Working Capital Loan Agreement with Allseas Investments, resulting in a further draw of $2.5 million by us and a total Working Capital Loan drawn amount of $7.5 million. On March 24, 2025, we entered into a Letter Agreement with Allseas Investments and Argentum Cedit Virtuti GCV, pursuant to which the Original Repayment Date under the Working Capital Loan Agreement was extended to September 30, 2025, with principal and interest now repayable on that date. During the second quarter of 2025, we repaid the entire outstanding loan and interest, amounting to $7.5 million and $0.5 million, respectively, and cancelled the Working Capital Loan Agreement.

2024 Credit Facility with ERAS Capital LLC and Gerard Barron

On March 22, 2024, we entered into an Unsecured Credit Facility with Gerard Barron, our Chief Executive Officer and Chairman, and ERAS Capital LLC, the family fund of our director, Andrei Karkar, pursuant to which, we may borrow from the 2024 Lenders up to $20 million in the aggregate ($10 million from each of the 2024 Lenders), from time to time, subject to certain conditions. All amounts drawn under the 2024 Credit Facility will bear interest at the 6-month SOFR, 180-day average plus 4.0% per annum payable in cash semi-annually (or plus 5% if paid-in-kind at maturity, at our election) on the first business day of each of June and January. We will pay an underutilization fee equal to 4.0% per annum payable semi-annually for any amounts that remain undrawn under the 2024 Credit Facility. We have the right to pre-pay the entire amount outstanding under the 2024 Credit Facility at any time, before the 2024 Credit Facility’s maturity of December 31, 2025. The 2024 Credit Facility also contains customary events of default. The 2024 Credit Facility will terminate automatically if we or any of our subsidiaries raise at least $50 million in the aggregate (i) through the issuance of any of our or our subsidiaries’ debt or equity securities, or (ii) in prepayments under an off-take agreement or similar commercial agreement. On August 13, 2024, we entered into the First Amendment to the 2024 Credit Facility with the 2024 Lenders, to increase the borrowing limit of the 2024 Credit Facility to $25 million in the aggregate ($12.5 million from each of the 2024 Lenders). On November 14, 2024, we entered into the Second Amendment to increase the borrowing limit to $38 million in the aggregate ($19 million from each of the 2024 Lenders) to the 2024 Credit Facility with ERAS Capital LLC and Gerard Barron, and to extend the maturity of the 2024 Credit Facility to December 31, 2025. As per the Second Amendment, the rate of underutilization fee was retroactively increased from March 22, 2024 to 6.5% on any undrawn amounts under the 2024 Credit Facility. On March 26, 2025, we entered into the Third Amendment to, among other things, increase the borrowing limit to $44 million in the aggregate ($22 million from each of the 2024 Lenders) and extend the maturity of the 2024 Credit Facility to June 30, 2026.

In the three months ended June 30, 2025, the Company incurred $58 thousand as interest expense and $0.7 million as underutilization fees. During the second quarter of 2025, the Company repaid outstanding interest payable amounting to $0.1 million of outstanding underutilization fees amounting to $0.9 million.

Critical Accounting Policies and Significant Judgments and Estimates

Our condensed consolidated interim financial statements have been prepared in accordance with U.S. GAAP. In the preparation of these financial statements, we are required to use judgment in making estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about items that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Except as described in Note 3 to our condensed consolidated interim financial statements included in this Quarterly Report on Form 10-Q, there have been no material changes to our critical accounting policies and estimates as compared to the critical accounting policies and estimates disclosed in our 2024 Annual Report on Form 10-K.

Emerging Growth Company Status

Section 102(b)(1) of the Jumpstart Our Business Startups (“JOBS”) Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can choose not to take advantage of the extended transition period and comply with the requirements that apply to non-emerging growth companies, and any such election to not take advantage of the extended transition period is irrevocable.

We are an “emerging growth company” as defined in Section 2(a) of the Securities Act and have elected to take advantage of the benefits of the extended transition period for new or revised financial accounting standards. For so long as we remain an emerging growth company, we may take advantage of certain exemptions from various reporting requirements and other burdens that are otherwise applicable generally to public companies. We will cease to qualify as an emerging growth company as of December 31, 2025. We may decide to early adopt such new or revised accounting standards to the extent permitted by such standards. This may make it difficult or impossible to compare our financial results with the financial results of another public company that is either not an emerging growth company or is an emerging growth company that has chosen not to take advantage of the extended transition period exemptions because of the potential differences in accounting standards used.

Cautionary Statements Regarding the NORI TRS and the NORI and TOML Initial Assessment

Except where otherwise stated, the scientific and technical information set forth in this Quarterly Report on Form 10-Q relating to the area our subsidiary TMC-USA has applied for an exploration license and commercial permit under DSHMRA (which includes part of the area under which our subsidiary NORI holds an exploration contract issued by the ISA) (“NORI Area D”) and the area under which our subsidiary TMC-USA has applied for an additional exploration license under DSHMRA (which includes part of the area under which our subsidiary NORI holds an exploration contract issued by the ISA and includes the area under which our subsidiary TOML holds an exploration contract issued by the ISA) (the “NORI and TOML Properties”)) is based on technical reports prepared in accordance with the SEC rules set forth in subpart 1300 of Regulation S-K (the “SEC Mining Rules”).

| · | In respect of NORI Area D, the pre-feasibility study in the technical report entitled “S-K 1300 NORI Area D Technical Report”, dated August 4, 2025 (the “NORI TRS”), prepared by AMC Consultants Pty Ltd. and other qualified persons, each a “qualified person” as defined in subpart 1300 of Regulation S-K; and

| · | In respect of the NORI and TOML Properties, the technical report entitled “Technical Report Summary—Initial Assessment of TOML and NORI Properties, Clarion-Clipperton Zone”, dated August 4, 2025 (the “NORI AND TOML Initial Assessment” together with the TRS, the “Technical Reports”), prepared by AMC Consultants Pty Ltd. and other qualified persons, each a “qualified person” as defined in subpart 1300 of Regulation S-K.

The pre-feasibility study included in the NORI TRS indicated that the development of NORI Area D is technically and economically viable. The pre-feasibility study, however, does not represent a feasibility study and does not support a development decision and additional project planning and design are needed to make this decision. In addition, the initial assessment included in the NORI and TOML Initial Assessment Report is a conceptual study of the potential viability of mineral resources in the NORI and TOML Properties. This initial assessment indicates that development of the mineral resource in the NORI and TOML Properties is potentially technically and economically viable; however, due to the preliminary nature of project planning and design, and the untested nature of the specific seafloor production systems at a commercial scale, economic viability has not yet been demonstrated. As a result, we plan to continue to estimate our resources and reserves in NORI Area D and the NORI and TOML Properties and further develop the project economics.

As used in this Quarterly Report on Form 10-Q or in the applicable report summary, the terms “pre-feasibility study,” “feasibility study,” “initial assessment,” “mineral reserve,” “probable mineral reserve,” proven mineral reserve,” “mineral resource,” “measured mineral resource,” “indicated mineral resource” and “inferred mineral resource”, as applicable, and other terms used herein are defined and used in accordance with the SEC Mining Rules.

The NORI TRS also does not include the conversion of all mineral resources included in NORI Area D to mineral reserves and does not include the conversion of any mineral resources to proven mineral reserves and the NORI and TOML Initial Assessment does not include the conversion of mineral resources to mineral reserves. You are specifically cautioned not to assume that any part or all of the mineral deposits in categorized as mineral resources will ever be converted into mineral reserves, as defined by the SEC. You are also cautioned that mineral resources do not have demonstrated economic value. Information concerning our mineral properties in the Technical Report and in this Quarterly Report on Form 10-Q includes information that has been prepared in accordance with the requirements of the SEC Mining Rules set forth in subpart 1300 of Regulation S-K. Under SEC standards, mineralization, such as mineral resources, may not be classified as a “reserve” unless the determination has been made that the mineralization would be economically and legally produced or extracted at the time of the reserve determination. Inferred mineral resources have a high degree of uncertainty as to their existence and to whether they can be economically or legally commercialized. Under the SEC Mining Rules, estimates of inferred mineral resources may not form the basis of an economic analysis. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. A significant amount of exploration must be completed in order to determine whether an inferred mineral resource may be upgraded to a higher category. Therefore, you are cautioned not to assume that all or any part of an inferred mineral resource exists, that it can be economically or legally commercialized, or that it will ever be upgraded to a higher category. Approximately 97% of the NORI Area D resource and approximately 6% of the NORI (Areas A to C) and TOML Properties resource are categorized as measured or indicated.

Likewise, you are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be upgraded to mineral reserves or that probable mineral reserves will ever be upgraded to proven mineral reserves. Until mineral deposits are actually mined and processed, mineral resources and mineral reserves must be considered as estimates only.

Further information on each of the polymetallic nodule areas in the CCZ and the Technical Reports referred to above can be found in our Current Report on Form 8-K filed with the SEC on August 4, 2025. The information contained in this Quarterly Report in Form 10-Q regarding NORI Area D and the NORI and TOML Properties has been derived from the Technical Reports, is subject to certain assumptions, qualifications and procedures described in the Technical Reports and is qualified in its entirety by the full text of the NORI TRS and the NORI and TOML Initial Assessment, which are filed as exhibit 96.1 and 96.2, respectively, to our Current Report on Form 8-K filed with the SEC on August 4, 2025.

The technical report entitled “Technical Report Summary – Initial Assessment of the NORI Property, Clarion-Clipperton Zone” dated as of March 17, 2021 (the “2021 NORI Initial Assessment”) and the technical report entitled “Technical Report Summary – TOML Mineral Resource, Clarion Clipperton Zone, Pacific Ocean” dated as of March 26, 2021 (the “2021 TOML Mineral Resource Statement”), each prepared by AMC Consultants Pty Ltd. and other qualified persons, have been superseded by the NORI TRS and the NORI and TOML Initial Assessment and therefore, the 2021 NORI Initial Assessment and the 2021 TOML Resource Statement and any summaries of or excerpts thereof should no longer be relied upon or used by investors for any reason unless specifically allowed by us.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to a variety of markets and other risks including the effects of change in interest rates, inflation and foreign currency translation and transaction risks as well as risks to the availability of funding sources, hazard events, specific asset risks, regulatory risks, public policy risks and technology risks. We also expect to be exposed to commodity risks if and when we commence commercial production.

Interest Rate Risk and Credit Risk

Interest rate risk is the risk that the fair value of our future cash flows and our financial instruments will fluctuate because of changes in market interest rates.

Our current practice is to invest excess cash in investment-grade short-term deposit certificates issued by reputable Canadian financial institutions with which we keep our bank accounts and management believes the risk of loss to be remote. We periodically monitor the investments we make and are satisfied with the credit ratings of our banks. Due to the current high cash need of our operating plan, we have kept our funds readily available, placed in secure, highly liquid interest-bearing investments, as at June 30, 2025.

Credit risk is a risk of loss that may arise on outstanding financial instruments should a counter party default on its obligation. Our receivables consist primarily of general sales tax due from the Federal Government of Canada and as a result, the risk of default is considered to be low. Once we commence commercial production, we expect our credit risk to rise with our increased customer base.

Regulatory Risk

Both the ISA and the U.S. regime under DSHMRA have not yet been used for commercial production of seafloor polymetallic nodules. To date, NOAA has not issued a commercial recovery permit, and while the legal framework is established, it has not yet been applied to the full lifecycle of a seabed mining project. Our April 2025 applications now under NOAA review, and each is subject to an initial determination as to full compliance and completeness under DSHMRA. There can be no assurance that such determinations will be favorable, that the applications will proceed to full review without delay, or that NOAA will not request additional information, modifications, or clarifications before accepting them for full review. There is also no assurance that any of our applications will result in NOAA granting us any exploration licenses or a commercial recovery permit on a timely basis or at all, or on commercially viable terms and conditions, and any such failure would materially and adversely affect our business, financial condition, liquidity, results of operations and prospects. Although we believe the regulations may allow for a direct or simultaneous application for a commercial recovery permit where sufficient environmental and technical data already exists, there is no assurance that NOAA will agree with this interpretation. There is no guarantee that NOAA’s proposed amendments that introduce a new consolidated application procedure under § 971.214, allowing submission of a single application for both an exploration license and commercial recovery permit, will be adopted as proposed or at all. If NOAA requires us to begin the DSHMRA permitting process with an exploration license, this would likely delay our intended commercialization timeline and increase permitting costs and complexity. In addition, there is no assurance that we will be able to comply with, or obtain a waiver of, the requirement under DSHMRA requirement that minerals be processed in the United States.

In addition, permitting under DSHMRA will subject us to a complex regulatory system in the United States which we are currently analyzing to determine applicability and how compliance will impact our development plans and potential commercial operations. For example, we will be subject to the Merchant Marine Act of 1920 and will need to be in full compliance with U.S. environmental laws, and NOAA may deny a commercial recovery permit if it determines that significant adverse environmental effects cannot be adequately mitigated. The review and approval process will also be subject to a full EIS process under NEPA, as well as public comment and potential legal challenge in U.S. courts by third parties. Although the recent Executive Order signed by President Trump on April 24, 2025 directs the Commerce Secretary to implement an expedited permitting process under DSHMRA, the timing of license or permit issuance remains uncertain, as there is no statutory deadline under DSHMRA and actual review timelines will depend on the scope and outcome of NOAA’s assessment.

Other Risks

We are exposed to a variety of markets and other risks including the effects of inflation and foreign currency translation, commodity pricing risks and transaction risks as well as risks to the availability of funding sources, hazard events specific asset risks, regulatory risks, public policy risks and technology risks. We also expect to be exposed to commodity risks if and when we commence commercial production.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act.

Disclosure controls and procedures are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of June 30, 2025, as a result of a material weakness in our internal control over financial reporting as described below.

Material Weaknesses in Internal Control over Financial Reporting

As previously disclosed in our 2024 Annual Report on Form 10-K, management identified a material weakness in the operating effectiveness of our internal controls over the accounting for significant non-routine transactions that resulted from the inadequate and untimely involvement of stakeholders and technical advisors with an appropriate level of expertise to account for a non-routine, unusual and complex transaction. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected on a timely basis.

This material weakness resulted in errors in the financial statements and related disclosures in our Quarterly Reports on Form 10-Q for the quarter ended March 31, 2023, and for the six months ended June 30, 2023 and nine months ended September 30, 2023. See Note 22 to the audited consolidated financial statements for the year ended December 31, 2023, included in our 2023 Annual Report on form 10-K for more information about these errors and our revisions to these previously issued financial statements in our financial statements as of and for the year ended December 31, 2023, as included in the 2023 Annual report on Form 10-K.

In order to remediate this material weakness, during 2024, we developed a policy to assist with the identification of significant, non-routine transactions and to define the processes to follow in addressing the accounting and reporting requirements of these transactions. In addition, we rolled out training on processes and controls related to significant, non-routine transactions and identifying circumstances under which we use technical advisors in connection with evaluating such transactions. During the fourth quarter of 2024 and in the second quarter of 2025, we identified several significant, non-routine transactions that occurred, and we applied the processes as required under the new policy. Although management believes the new policy, processes and training worked effectively for these significant, non-routine transaction, the new internal control over significant, non-routine transactions needs to be in operation and tested for sufficient instances, including a successful evaluation from our 2025 year-end audit procedures, in order to be considered effective and, therefore, these changes can only be deemed effective once they have been in place over a longer time period and applied in additional instances.

We will continue to review the effectiveness of our newly implemented controls and make improvements as warranted. This is no assurance, however, that these control modifications will ultimately have the intended effects.

​

Table of Contents

Notwithstanding our material weakness, we have concluded that our unaudited condensed consolidated interim financial statements included in this Quarterly Report on Form 10-Q fairly present in all material respects our financial condition, results of operations and cash flows for the periods presented in conformity with U.S. GAAP.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation of such internal controls that occurred during the second quarter ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Disclosure Controls and Procedures

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and implemented, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues within a company are detected. The inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple errors or mistakes. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

Except as set forth below, we are not currently a party to any material legal proceedings.

On October 28, 2021, a shareholder filed a putative class action against us, one of our executive and former director in federal district court for the Eastern District of New York, captioned Caper v. TMC The Metals Company Inc. F/K/A Sustainable Opportunities Acquisition Corp., Gerard Barron and Scott Leonard. The complaint alleges that all defendants violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder, and Messrs. Barron and Leonard violated Section 20(a) of the Exchange Act, by making false and/or misleading statements and/or failing to disclose information about our operations and prospects during the period from March 4, 2021 and October 5, 2021. On November 15, 2021, a second complaint containing substantially the same allegations was filed, captioned Tran v. TMC the Metals Company, Inc. These cases have been consolidated. On March 6, 2022, a lead plaintiff was selected. An amended complaint was filed on May 12, 2022, reflecting substantially similar allegations, with the Plaintiff seeking to recover compensable damages caused by the alleged wrongdoings. We deny any allegations of wrongdoing and filed and served the plaintiff a motion to dismiss on July 12, 2022 and intend to defend against this lawsuit. On July 12, 2023, an oral hearing on the motion to dismiss was held. On July 9, 2025, the Court granted our motion to dismiss with prejudice, and the case was dismissed in its entirety. No appeal was filed and the matter is now considered closed.

On January 23, 2023, investors in the 2021 private placement from the Business Combination filed a lawsuit against us in the Commercial Division of New York Supreme Court, New York County, captioned Atalaya Special Purpose Investment Fund II LP et al. v. Sustainable Opportunities Acquisition Corp. n/k/a TMC The Metals Company Inc., Index No. 650449/2023 (N.Y. Sup. Ct.). We filed a motion to dismiss on March 31, 2023, after which the plaintiffs filed an amended complaint on June 5, 2023. The amended complaint alleges that we breached the representations and warranties in the plaintiffs’ private placement Subscription Agreements and breached the covenant of good faith and fair dealing. The Plaintiffs are seeking to recover compensable damages caused by the alleged wrongdoings. We deny any allegations of wrongdoing and filed a motion to dismiss the amended complaint on July 28, 2023. On December 7, 2023, the Court granted our motion to dismiss the claim for breach of the covenant of good faith and fair dealing and denied our motion to dismiss the breach of the Subscription Agreement claim. We filed a notice of appeal regarding the Court’s denial of our motion to dismiss the breach of the Subscription Agreement claim. The appeal was heard on November 8, 2024. The NY Appellate Division upheld the lower court’s ruling in December 2024, moving the case into the discovery phase. There is no assurance that we will be successful in our defense of this lawsuit or that insurance will be available or adequate to fund any settlement or judgment or the litigation costs of this action. Such losses or range of possible losses cannot be reliably estimated.

On November 8, 2024, a shareholder filed a putative class action against us and certain executives in federal district court for the Central District of California, captioned Lin v. TMC The Metals Company Inc., Gerard Barron, and Craig Shesky. The complaint alleges that all defendants violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder, and Messrs. Barron and Shesky violated Section 20(a) of the Exchange Act, by making false and/or misleading statements and/or failing to disclose information regarding the classification of the non-financial asset received from our partnership with Low Carbon Royalties Inc. and the derecognition of the capitalized exploration contract related to NORI. The alleged misstatements and omissions pertain to our initial classification of this non-financial asset as a gain on disposition (being a sale of future revenue) and subsequent reclassification thereof as a royalty liability (and re-capitalization of the exploration contract) and the restatement of our previously issued financial statements as a result thereof for the three months ended March 31, 2023, the six months ended June 30, 2023 and the nine months ended September 30, 2023 in March 2024. The complaint purports to represent a class of shareholders who acquired our securities between May 12, 2023, and March 25, 2024, and seeks to recover compensable damages caused by the alleged wrongdoings. On February 6, 2025, the Court appointed a lead plaintiff. An amended complaint was filed on March 6, 2025. Pursuant to court-approved scheduling, we filed our motion to dismiss on April 10, 2025. The lead plaintiff filed an opposition on May 15, 2025, and we filed our reply on June 5, 2025. On June 18, 2025, the Court granted our motion to dismiss in full but granted plaintiffs leave to amend. The plaintiffs filed a Second Amended Complaint on July 2, 2025. Our motion to dismiss the Second Amended Complaint was filed on August 6, 2025, the plaintiff’s opposition is expected to be filed by September 9, 2025, and our reply is expected to be filed by September 23, 2025. We intend to continue defending against the lawsuit. There can be no assurance, however, that we will be successful in our defense, or that insurance will be available or adequate to fund any settlement or judgment or the litigation costs of this action. Due to the early stage of this litigation, such losses or range of possible losses cannot be reliably estimated.

ITEM 1A. RISK FACTORS.

You should carefully review and consider the information regarding certain factors that could materially affect our business, consolidated financial condition or results of operations set forth under Item 1A. Risk Factors in our 2024 Annual Report on Form 10-K and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2025. Other than noted below, there have been no material changes from or additions to the risk factors disclosed in those reports. We may disclose changes to risk factors or additional factors from time to time in our future filings with the SEC.

Table of Contents

We are reliant on third parties to conduct independent analyses with respect to our business, and any inaccuracies in such analyses could have a material adverse effect on our offshore collection and onshore processing and refining objectives.

We rely upon third-party consultants, engineers, analysts, scientists, and others to provide analyses, reviews, reports, advice, and opinions regarding our potential projects. For example, the NORI Area D Pre-Feasibility Study (“PFS”) and the Initial Assessment of the Remaining NORI and TOML Resource contain mineral resource and, in the case of the PFS, mineral reserve estimates and other technical and economic information with respect to our contract areas. While these studies have been prepared by qualified persons, they are inherently based on assumptions and interpretations that may change over time or prove inaccurate. There is a risk that such analyses, reviews, reports, advice, opinions, and projects are incorrect or become outdated over time or as our plans change, in particular with respect to resource and reserve estimation, process development, recommendations for products to be produced, capital and operating cost estimates, and forecasted revenue streams. Both the PFS and the Initial Assessment are subject to the risks and uncertainties that apply to early-stage technical studies, including that results may not be realized as currently presented. Uncertainties are also inherent in such estimations.

Mineral resource and mineral reserve estimates from the contract areas of NORI and TOML are only estimates.

Estimates of mineral resources and mineral reserves from the contract areas of NORI and TOML described in our SEC filings and reported in technical reports prepared by AMC depend on geological interpretation and statistical inferences or assumptions drawn from survey data and recovery and sampling analysis, which might prove to be materially inaccurate. While these reports have been provided by experts, there is a degree of uncertainty attributable to the estimation of mineral resources and mineral reserves. Except for the Probable Mineral Reserves declared in the PFS for the Initial Mining Area of NORI Area D, mineral reserves have not been defined for our other contract areas and will require completion of further studies. The PFS is not a feasibility study and does not support a development decision, and the Initial Assessment is preliminary in nature, contains no reserves, and is not sufficient to determine the economic viability of a mining project. Until mineral resources and mineral reserves are actually collected and processed on a commercial scale, the quantity of metal and nodule abundance must be considered as estimates only, and no assurance can be given that the indicated levels of metals will be produced. The estimation of mineral reserves and mineral resources is an iterative process and is, at times, partially dependent upon the judgment of the persons preparing the estimates. The process relies on the quantity and quality of available data and is based on knowledge, experience, statistical analysis of data and industry practices. Valid estimates made at a given time may significantly change when new information becomes available. Estimated mineral reserves and mineral resources may have to be recalculated based on changes in metal prices, further exploration or development activity, actual production experience, or changes in operating or regulatory conditions. This could materially and adversely affect estimates of the volume or grade of mineralization, estimated recovery rates, or other important factors that influence mineral reserve and mineral resource estimates. The extent to which mineral resources may ultimately be reclassified as mineral reserves is dependent upon the demonstration of their profitable recovery. Any material changes in volume and grades of mineralization will affect the economic viability of placing a property into production and a property’s return on capital. We cannot provide assurance that polymetallic nodules can be collected or processed profitably. The mineral resource and mineral reserve estimates in our SEC filings have been determined and valued based on assumed future metal prices, cut-off grades, production rates, and operating costs that may prove to be inaccurate. Extended declines in the market price for nickel, manganese, copper, and cobalt may render portions of our mineralization uneconomic and result in reduced reported volume and grades, which in turn could have a material adverse effect on our financial performance, financial position, and results of operations. In addition, inferred mineral resources have a great amount of uncertainty as to their existence and their economic and legal feasibility. You should not assume that any part of an inferred mineral resource will be upgraded to a higher category or that any of the mineral resources will be reclassified as mineral reserves. As of the PFS, approximately 51 million tonnes of the measured and indicated mineral resource in the NORI Area D have been classified as Probable Mineral Reserves, with the balance of the resource remaining in the measured and indicated categories.
