Description of Organization and Business Operations

Note 1 — Description of Organization and Business Operations

Sustainable Opportunities Acquisition Corp. (the “Company”) is a newly organized blank check company incorporated as a Cayman Islands exempted company on December 18, 2019. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (the “Business Combination”). The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies.

As of June 30, 2021, the Company had not commenced any operations. All activity for the period from December 18, 2019 (inception) through June 30, 2021 relates to the Company’s formation, the initial public offering (the “Initial Public Offering”), and, since the closing of the Initial Public Offering, a search for a business combination candidate. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on cash from the proceeds derived from the Initial Public Offering and interest income earned on investments held in Trust Account.

Proposed Business Combination and Related Transactions

On March 4, 2021, the Company entered into a Business Combination Agreement (the “Business Combination Agreement”), by and among the Company, 1291924 B.C. Unlimited Liability Company, an unlimited liability company existing under the laws of British Columbia, Canada (“NewCo Sub”), and DeepGreen Metals Inc., a company existing under the laws of British Columbia, Canada (“DeepGreen”).

Pursuant to the Business Combination Agreement, the Company will migrate to and be continued as a company in British Columbia, Canada (the “SOAC Continuance”). Following the SOAC Continuance, pursuant to a plan of arrangement (the “Plan of Arrangement”) under the Business Corporations Act (British Columbia), (i) the Company will acquire all of the issued and outstanding shares in the capital of DeepGreen (the “DeepGreen Shares”) from DeepGreen shareholders in exchange for the Company’s ordinary shares (as defined below) and Company Earnout Shares (as defined below) (the “Share Exchange”), (ii) DeepGreen will become a wholly-owned subsidiary of the Company, and (iii) DeepGreen and NewCo Sub will amalgamate to continue as one unlimited liability company, in each case, on the terms and subject to the conditions set forth in the Business Combination Agreement and the Plan of Arrangement and in accordance with the provisions of applicable law.

Each option to purchase ordinary shares in the capital of the Company (the “DeepGreen Options”) will become an option to purchase SOAC ordinary shares and Company Earnout Shares on the same terms and conditions (including applicable vesting, expiration and forfeiture provisions) that applied to the corresponding DeepGreen Options immediately prior to closing of the Business Combination.

The Proposed Business Combination is expected to close in the third quarter of 2021, following the receipt of the required approval by the Company’s shareholders and the fulfillment of other conditions.

The shareholders and the optionholders of DeepGreen will be entitled to receive, in exchange for their DeepGreen Shares or DeepGreen Options, as applicable, an aggregate of (i) a number of shares in the capital of the Company or comparable equity awards that are settled or are exercisable for shares in the capital of the Company, as applicable, based on an implied DeepGreen equity value of $2.25 billion after giving effect to the SOAC Continuance (the “SOAC Ordinary shares”), (ii) 5,000,000 Class A Special Shares, (iii) 10,000,000 Class B Special Shares, (iv) 10,000,000 Class C Special Shares, (v) 20,000,000 Class D Special Shares, (vi) 20,000,000 Class E Special Shares, (vii) 20,000,000 Class F Special Shares, (viii) 25,000,000 Class G Special Shares and (ix) 25,000,000 Class H Special Shares, in each case, in the capital of the Company (collectively, the “Company Earnout Shares”), or, as applicable, options to purchase such SOAC Ordinary shares and Company Earnout Shares.

such investors, substantially concurrently with the Closing (as defined in the Business Combination Agreement), an aggregate of 33,030,000 shares of SOAC Ordinary shares for $10.00 per share, for aggregate gross proceeds of $330,300,000 (the “PIPE Financing”). The closing of the PIPE Financing is contingent upon, among other things, the substantially concurrent consummation of the Business Combination. The Subscription Agreements provide that the Company will grant the investors in the PIPE Financing certain customary registration rights. The PIPE Financing is contingent upon, among other things, the substantially concurrent closing of the Business Combination.

The Company evaluated subsequent events and transactions that occurred after the balance sheet date up to the date the financial statements were issued. Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements which have not previously been disclosed within the financial statements.

Sponsor, Initial Public Offering and Private Placement

The Company’s sponsor is Sustainable Opportunities Holdings LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on May 5, 2020. On May 8, 2020, the Company consummated its Initial Public Offering of 30,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”) at $10.00 per Unit, generating gross proceeds of $300.0 million, and incurring offering costs of approximately $17.4 million, inclusive of $10.5 million in deferred underwriting commissions (Note 5).

Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 9,500,000 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant in a private placement to the Sponsor, generating gross proceeds of $9.5 million (Note 4).

Trust Account

Upon the closing of the Initial Public Offering and the Private Placement, $300.0 million ($10.00 per Unit) of the net proceeds of the sale of the Units in the Initial Public Offering and the Private Placement were placed in a trust account (the “Trust Account”), located in the United States at JP Morgan Chase Bank, N.A., with Continental Stock Transfer & Trust Company acting as trustee, and invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting the conditions of paragraphs (d)(2), (d)(3) and (d)(4) of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

Initial Business Combination

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the assets held in the Trust Account (as defined below) (excluding the deferred underwriting commissions and taxes payable on income earned on the Trust Account) at the time of the signing of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act 1940, as amended (the “Investment Company Act”).

The Company will provide the holders (the “Public Shareholders”) of its Class A ordinary shares, par value $0.0001 per share sold in the Initial Public Offering (the “Public Shares”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.00 per Public Share). The per-share amount to be distributed to Public Shareholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriter (as discussed in Note 5). These Public Shares will be recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” In such case, the Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and a majority of the shares voted are voted in favor of the Business Combination. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to the amended and restated memorandum and articles of association, which the Company adopted upon the consummation of the Initial Public Offering (the “Amended and Restated Memorandum and Articles of Association”) conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, shareholder approval of the transactions is required by law, or the Company decides to obtain shareholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks shareholder approval in connection with a Business Combination, the Initial Shareholders (as defined below) have agreed to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. In addition, the Initial Shareholders have agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination.

Notwithstanding the foregoing, the Amended and Restated Memorandum and Articles of Association provide that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Class A ordinary shares sold in the Initial Public Offering, without the prior consent of the Company.

The Company’s Sponsor, officers and directors (the “Initial Shareholders”) have agreed not to propose an amendment to the Amended and Restated Memorandum and Articles of Association that would affect the substance or timing of the Company’s obligation to provide holders of its Public Shares the right to have their shares redeemed in connection with its initial business combination or to redeem 100% of its Public Shares if the Company does not complete a Business Combination within 18 months from the closing of the Initial Public Offering, or November 8, 2021 (the “Combination Period”) unless the Company provides the Public Shareholders with the opportunity to redeem their Class A ordinary shares in conjunction with any such amendment.

If the Company is unable to complete a Business Combination within the Combination Period, the Company will: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay for its tax obligations, if any (less up to $100,000 of interest to pay dissolution expenses) divided by the number of the then-outstanding Public Shares, which redemption

will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii), to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

The Initial Shareholders have agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Shareholders acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriter has agreed to waive its rights to its deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or to any claims under the Company’s indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Going Concern Consideration

As of June 30, 2021, the Company had approximately $293 thousand in cash and a working capital deficit of approximately $6.8 million.

Until the consummation of a Business Combination, the Company will be using the funds not held in the Trust Account for identifying and evaluating prospective acquisition candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to acquire, and structuring, negotiating and consummating the Business Combination. The Company will need to raise additional capital through loans or additional investments from its Sponsor, stockholders, officers, directors, or third parties. The Company’s officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company’s working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses.

The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all. These conditions raise substantial doubt about the Company’s ability to continue as a going concern through November 8, 2021. These financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.

Note 1 — Description of Organization and Business Operations

As of December 31, 2020, the Company had not commenced any operations. All activity for the period from December 18, 2019 (inception) through December 31, 2020 relates to the Company’s formation and the initial public offering (the “Initial Public Offering”) described below, and, since the closing of the Initial Public Offering, a search for a business combination candidate. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on cash from the proceeds derived from the Initial Public Offering and interest income earned on investments held in Trust Account.

Initial Business Combination

The Company will provide the holders (the “Public Shareholders”) of its Class A ordinary shares, par value $0.0001 per share sold in the Initial Public Offering (the “Public Shares”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer.

Proposed Business Combination

Pursuant to the Business Combination Agreement, the Company will migrate to and be continued as a company in British Columbia, Canada (the “SOAC Continuance”). Following the SOAC Continuance, pursuant to a plan of arrangement (the “Plan of Arrangement”) under the Business Corporations Act (British Columbia), (i) the Company will acquire all of the issued and outstanding shares in the capital of DeepGreen (the “DeepGreen Shares”) from DeepGreen shareholders in exchange for the Company’s common shares (as defined below) and Company Earnout Shares (as defined in Note 9) (the “Share Exchange”), (ii) DeepGreen will become a wholly-owned subsidiary of the Company, and (iii) DeepGreen and NewCo Sub will amalgamate to continue as one unlimited liability company, in each case, on the terms and subject to the conditions set forth in the Business Combination Agreement and the Plan of Arrangement and in accordance with the provisions of applicable law.

Concurrently with the execution of the Business Combination Agreement, the Company entered into subscription agreements (the “Subscription Agreements”) with certain institutional and accredited investors, pursuant to which such investors agreed to subscribe for and purchase, and the Company agreed to issue and sell to such investors, substantially concurrently with the Closing (as defined in the Business Combination Agreement), an aggregate of 33,030,000 shares of SOAC Ordinary shares for $10.00 per share, for aggregate gross proceeds of $330,300,000 (the “PIPE Financing”). The closing of the PIPE Financing is contingent upon, among other things, the substantially concurrent consummation of the Business Combination. The Subscription Agreements provide that the Company will grant the investors in the PIPE Financing certain customary registration rights. The PIPE Financing is contingent upon, among other things, the substantially concurrent closing of the Business Combination. See Note 9.

Going Concern Consideration

As of December 31, 2020, the Company had approximately $1.3 million in cash and a working capital deficit of approximately $372,000.

Basis of Presentation

The accompanying financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for financial information and pursuant to the rules and regulations of the SEC.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised, and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with other public companies difficult or impossible because of the potential differences in accounting standards used.

Condensed Financial Information Disclosure [Abstract]

Restatement of Previously Issued Financial Statements

Note 2 — Restatement of Previously Issued Financial Statements

On April 12, 2021, the Staff of the SEC issued a statement entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies.” In the statement, the SEC Staff, among other things, highlighted potential accounting implications of certain terms that are ordinary in warrants issued in connection with the initial public offerings of special purpose acquisition companies such as the Company. As a result of the Staff statement and in light of evolving views as to certain provisions ordinarily included in warrants issued by special purpose acquisition companies, the Company’s management re-evaluated the accounting for our Warrants under ASC 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity, and concluded that they do not meet the criteria to be classified in shareholders’ equity. Since the Warrants meet the definition of a derivative under ASC 815-40, the Company has restated the financial statements to classify the Warrants as liabilities on the balance sheet at fair value, with subsequent changes in their respective fair values recognized in the statement of operations at each reporting date.

The Company’s prior accounting treatment for the Warrants was equity classification rather than as derivative liabilities. Accounting for the Warrants as liabilities pursuant to ASC 815-40 requires that the Company re-measure the Warrants to their fair value each reporting period and record the changes in such value in the statement of operations. Accordingly, the Company has restated the value and classification of the Warrants in our financial statements included herein (“Restatement”).

In April 2021, the Company concluded that, because of a misapplication of the accounting guidance related to its warrants issued in connection with its initial public offering (“Public Warrants”), as well as warrants issued in a private sale simultaneous to the initial public offering (“Private Placement Warrants”) that the Company issued in May 2020, the Company’s previously issued financial statements as of May 8, 2020, as of and for the year ended December 31, 2020 as well as the interim periods ended June 30, 2020 and September 30, 2020 (the “Affected Periods”) should no longer be relied upon. As such, the Company is restating its financial statements for the Affected Periods in this Annual Report. The following summarizes the effect of the Restatement on each financial statement line item for each period presented herein.

Summary of Significant Accounting Policies

Note 2 — Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the unaudited consolidated financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the periods presented. Operating results for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 or for any future interim periods.

The accompanying unaudited consolidated financial statements should be read in conjunction the financial statements and notes thereto included in with the Company’s Annual Report as amended on Form 10-K/A for the year ended December 31, 2020 as filed with the SEC on May 24, 2021.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation. Activities in relation to the noncontrolling interest are not considered to be significant and are, therefore, not presented in the accompanying consolidated financial statements.

Emerging Growth Company

Further, Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard.

This may make comparison of the Company’s financial statements with other public companies difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of the financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date the financial statements and the reported amounts of expenses during the reporting periods. Actual results could differ from those estimates.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000 and investments held in Trust Account. The Company has not experienced losses on these accounts.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of June 30, 2021 and December 31, 2020, respectively.

Investments Held in Trust Account

The Company’s portfolio of marketable securities is comprised solely of U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in any open-ended investment company that holds itself out as a money market fund selected by the Company meeting the conditions of paragraphs (d)(2), (d)(3) and (d)(4) of Rule 2a-7 of the Investment Company Act. Upon the closing of the Initial Public Offering and the Private Placement, $300 million was placed in the Trust Account and invested in money market funds that invest in U.S. government securities. All of the Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of investments held in Trust Account are included in net gain on investments held in Trust Account in the accompanying statement of operations. The estimated fair values of investments held in Trust Account are determined using available market information.

Fair Value Measurement

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:

• Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets;

• Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and

• Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

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.

Fair Value of Financial Instruments

As of June 30, 2021 and December 31, 2020, the carrying values of cash, prepaid expenses, and accounts payable approximate their fair values due to the short-term nature of the instruments. As of June 30, 2021, the Company’s portfolio of investments held in Trust Account is comprised entirely of investments in money market funds that invest in U.S. government securities.

The Warrants are accounted for as liabilities pursuant to ASC 815-40 and are measured at fair value as of each reporting period. Changes in the fair value of the Warrants are recorded in the statement of operations each period.

Warrant Liabilities

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815-15. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.

The Company issued 15,000,000 warrants as part of the units offered in its Initial Public Offering and, simultaneously with the closing of Initial Public Offering, the Company issued in a private placement an aggregate of 9,500,000 private placement warrants. The Company accounts for the Warrants in accordance with the guidance contained in ASC 815-40 under which the Warrants do not meet the criteria for equity treatment and must be recorded as liabilities. Accordingly, the Company classifies the Warrants as liabilities at their fair value and adjusts the warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s statement of operations. The fair value of the Public Warrants has been estimated using the Public Warrants’ quoted market price. The Private Placement Warrants are valued using a Modified Black Scholes Option Pricing Model.

Class A Ordinary Shares subject to possible redemption

Class A ordinary shares subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable Class A ordinary shares (including Class A ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, as of June 30, 2021, 30,000,000 Class A ordinary shares subject to possible redemption were presented at redemption value as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheet.

Net Income (Loss) Per Ordinary Share

The Company applies the two-class method in calculating earnings per share. Net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of ordinary shares outstanding during the periods. An aggregate of 30,000,000 and 22,726,721 Class A ordinary shares subject to possible redemption at June 30, 2021 and December 31, 2020, respectively have been excluded from the calculation of basic loss per ordinary share, since such shares, if redeemed, only participate in their pro rata share of the Trust earnings. The Company has not considered the effect of the warrants sold in the Initial Public Offering and Private Placement to purchase an aggregate of 24,500,000 Class A ordinary shares in the calculation of diluted loss per ordinary share, since the inclusion of such warrants would be anti-dilutive. As a result, diluted net income (loss) per ordinary share is the same as basic net income (loss) per ordinary share for the periods presented.

Reconciliation of Net Income (Loss) per Ordinary Share

The Company’s net income (loss) is adjusted for the portion of income (loss) that is attributable to ordinary shares subject to redemption, as these shares only participate in the earnings of the Trust Account and not the income or losses of the Company. Accordingly, basic and diluted loss per ordinary share is calculated as follows:

	For the three months ended June 30, 2021			For the three months ended June 30, 2020			For the six months ended June 30, 2021			For the six months ended June 30, 2020

Income Taxes

FASB ASC Topic 740, “Income Taxes,” prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits as of June 30, 2021 and December 31, 2020. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of June 30, 2021 and December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman Islands income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statements. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

Recent Accounting Standards

The Company’s management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.

Offering Costs Associated with the Initial Public Offering

The Company complies with the requirements of ASC 340-10-S99 and SEC Staff Accounting Bulletin (“SAB”) Topic 5A — “Expenses of Offering”. Offering costs consist of legal, accounting, underwriting fees and other costs that were directly related to the Initial Public Offering. Upon the completion of the Initial Public Offering on May 8, 2020, the offering costs were allocated to the separable financial instruments based on their relative fair value compared to the proceeds received, with $877,647 being expensed on fair value of warrant liabilities relative to Initial Public Offering proceeds.

Warrant Liabilities

The Company issued 15,000,000 warrants as part of the units offered in its Initial Public Offering and, simultaneously with the closing of Initial Public Offering, the Company issued in a private placement an aggregate of 9,500,000 private placement warrants. The Company accounts for the Warrants in accordance with the guidance contained in ASC 815-40-15-7D and 7F under which the Warrants do not meet the criteria for equity treatment and must be recorded as liabilities. Accordingly, the Company classifies the Warrants as liabilities at their fair value and adjusts the warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s statement of operations. The fair value of the Public Warrants was initially measured using a Modified Black Scholes Option Pricing Model and has subsequently been estimated using the Public Warrants’ quoted market price. The Private Placement Warrants are valued using a Modified Black Scholes Option Pricing Model.

Class A Ordinary Shares subject to possible redemption

Class A ordinary shares subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable Class A ordinary shares (including Class A ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, as of December 31, 2020, 22,726,721 Class A ordinary shares subject to possible redemption were presented at redemption value as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheet.

Net Loss Per Ordinary Share

The Company applies the two-class method in calculating earnings per share. Net loss per share is computed by dividing net loss by the weighted-average number of ordinary shares outstanding during the periods. An aggregate of 22,726,721 and 0 Class A ordinary shares subject to possible redemption at December 31, 2020 and 2019, respectively has been excluded from the calculation of basic loss per ordinary share, since such shares, if redeemed, only participate in their pro rata share of the Trust earnings. The Company has not considered the effect of the warrants sold in the Initial Public Offering and Private Placement to purchase an aggregate of 24,500,000 Class A

ordinary shares in the calculation of diluted loss per ordinary share, since the exercise of the warrants are contingent upon the occurrence of future events. As a result, diluted net loss per ordinary share is the same as basic net loss per ordinary share for the periods presented.

Reconciliation of Net Loss per Ordinary Share

The Company’s net loss is adjusted for the portion of income (loss) that is attributable to ordinary shares subject to redemption, as these shares only participate in the earnings of the Trust Account and not the income or losses of the Company. Accordingly, basic and diluted loss per ordinary share is calculated as follows:

	For the Year Ended December 31, 2020			For the Period from December 18, 2019 (inception) to December 31, 2019

Income Taxes

FASB ASC Topic 740, “Income Taxes,” prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits as of December 31, 2020 and December 31, 2019. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of December 31, 2020 and December 31, 2019. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

Recent Accounting Standards

Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

These unaudited condensed consolidated financial statements are prepared in accordance with US Generally Accepted Accounting Principles (“US GAAP”) for interim financial statements. Accordingly, certain information and footnote disclosures required by US GAAP have been condensed or omitted in these unaudited consolidated financial statements pursuant to such rules and regulation. In management’s opinion, these unaudited 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, stockholder’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, 2021 or for any other period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited annual consolidated financial statements for the year ended December 31, 2020. The Company has applied the same accounting policies as in the prior year.

Basis of Measurement

These unaudited condensed consolidated financial statements have been prepared under the historical cost convention and are presented in United States (“US”) dollars.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts in the unaudited consolidated financial statements and the notes thereto. Significant estimates and assumptions reflected in these unaudited consolidated financial statements include, but are not limited to, the valuation of common-share based payments, including valuation of the incentive stock options (Note 7) and the common shares issued to Maersk Supply Service A/S (“Maersk”) (Note 4 & 6). Actual results could differ materially from those estimates.

Recent Accounting Pronouncements Issued and Adopted

i. Accounting for Debt with Conversion and Other Options

In August 2020, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU” 2020-08, “Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivative and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40)”, which simplifies the accounting for convertible instruments by reducing the number of accounting models and requiring that a convertible instrument be accounted for as a single liability measured at amortized cost. Further the ASU 2020-08 amends the earnings per share guidance by requiring the diluted earnings per share calculation for convertible instruments to follow the if-converted method, with the use of the treasury stock method no longer permitted. The ASU 2020-08 is effective for fiscal period after December 15, 2021, with early adoption permitted, but no earlier than fiscal years and interim periods within those fiscal years, beginning after December 15, 2020. The ASU 2020-08 allows either a modified retrospective method of transition or a fully retrospective method of transition, with any adjustments recognized as an adjustment to the opening balance of deficit. The Company adopted this standard on January 1, 2021. The standard did not have any impact on the Company’s historical financial statements but was applied to recognize the impact of the convertible debentures issued during February 2021 (Note 5).

Related Party Transactions	Note 4 — Related Party Transactions Founder Shares On December 31, 2019, the Sponsor purchased 8,625,000 shares (the “Founder Shares”) of the Company’s Class B ordinary shares, par value $0.0001 for an aggregate price of $25,000. In March 2020, the Sponsor transferred 30,000 Founder Shares to each of the Company’s independent directors. The Founder Shares will automatically convert into Class A ordinary shares at the time of the Company’s initial Business Combination and are subject to certain transfer restrictions, as described in Note 6. The Sponsor had agreed to forfeit up to 1,125,000 Founder Shares to the extent that the over-allotment option was not exercised in full by the underwriter so that the Founder Shares will represent 20.0% of the Company’s issued and outstanding shares after the Initial Public Offering. The over-allotment option expired in June 2020; thus, these Founder Shares were forfeited accordingly. The Initial Shareholders agreed, subject to limited exceptions, not to transfer, assign or sell any of their Founder Shares until the earlier to occur of: (A) one year after the completion of the initial Business Combination or (B) subsequent to the initial Business Combination, (x) if the last sale price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination, or (y) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property. Private Placement Warrants Simultaneously with the closing of the Initial Public Offering, the Company consummated the Private Placement of 9,500,000 Private Placement Warrants at a price of $1.00 per Private Placement Warrant to the Sponsor, generating gross proceeds of $9.5 million. Each Private Placement Warrant is exercisable for one whole Class A ordinary share at a price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable and exercisable on a cashless basis so long as they are held by the Sponsor or its permitted transferees. The Sponsor and the Company’s officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the initial Business Combination. Related Party Loans On December 31, 2019, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the “Note”). This loan was non-interest bearing and payable upon the completion of the Initial Public Offering. The Company borrowed approximately $163,000 under the Note and fully repaid this amount on May 8, 2020. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of the proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post Business Combination entity at a price of $1.00 per warrant. The warrants would be identical to the Private Placement Warrants. As of June 30, 2021, the Company had no borrowings under the Working Capital Loans. Administrative Support Agreement The Company entered into an agreement, commencing on May 8, 2020 through the earlier of the Company’s consummation of a Business Combination and its liquidation, to reimburse the Sponsor a total of $10,000 per month for office space, secretarial and administrative services. The Company incurred and paid $30,000 and $60,000 for the three and six months ended June 30, 2021, respectively, and $20,000 for the three and six months ended June 30, 2020 respectively, in expenses in connection with such services and recorded in general and administrative expenses in the condensed statements of operations.

Such commitment has flexibility where the amount can be reduced by the ISA and such reduction would be dependent upon various factors including the success of the exploration programs and the availability of funding. As at December 31, 2020 the Company expended approximately $4.7 million. DeepGreen is due to discuss the progress since the acquisition of the TOML Group with the ISA later during 2021. Offtake Agreements, On May 25, 2012, the Company’s wholly owned subsidiary, DGE, and Glencore International AG (“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 at a DGE owned processing facility from nodules derived from the NORI Area at LME referenced market pricing with allowances for product quality and delivery location. Both the copper and nickel offtake agreements are for the life of the Company’s rights to the NORI Area. 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. Sponsorship Agreements On July 5, 2017, the Republic of Nauru (“Nauru”), the Nauru Seabed Minerals Authority and NORI entered into a sponsorship agreement (the “NORI Sponsorship Agreement”) formalising certain obligations of the parties in relation to NORI’s exploration and potential exploitation of the NORI Area. Upon reaching a minimum level of nodule production from the tenement area, NORI will pay Nauru a seabed mineral recovery payment based on the wet tonnes of polymetallic nodules recovered from the tenement area. In addition, NORI will pay an administration fee each year to Nauru for such administration and sponsorship, which is subject to review and increase in the event that NORI is granted an ISA exploitation contract. On March 8, 2008, the Kingdom of Tonga (“Tonga”) and TOML entered into a sponsorship agreement (the “TOML Sponsorship Agreement”) formalising certain obligations of the parties in relation to TOML’s exploration and potential exploitation of the TOML Area. Upon reaching a minimum recovery level of nodule production from the tenement area, TOML has agreed to pay Tonga a seabed mineral recovery payment based on the wet tonnes of polymetallic nodules recovered from the tenement area. In addition, TOML has agreed to pay the reasonable direct costs incurred by Tonga to administer the ISA obligations of Tonga to the ISA.

Fair Value Measurements

Note 7 — Fair Value Measurements

The Company follows the guidance in ASC 820 for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period, and non-financial assets and liabilities that are re-measured and reported at fair value at least annually.

The following table presents our fair value hierarchy for liabilities measured at fair value on a recurring basis as of June 30, 2021:

June 30, 2021

	Level 1		Level 2		Level 3		Total
Warrant liabilities:
Public Warrants	$	21,600,000	$	—	$	—	$	21,600,000
Private Placement Warrants		—		—		14,155,000		14,155,000
Total warrant liabilities	$	21,600,000	$	—	$	14,155,000	$	35,755,000

The Private Placement Warrants were valued using a modified Black Scholes Model including inputs from a Monte Carlo simulation, which is considered to be a Level 3 fair value measurement. The Monte Carlo simulation’s primary unobservable input utilized in determining the fair value of the Warrants is the probability of consummation of the Business Combination. The probability assigned to the consummation of the Business Combination was 88% which was estimated based on the observed success rates of business combinations for special purpose acquisition companies.

The following table provides quantitative information regarding Level 3 fair value measurements inputs at their measurement dates:

	As of June 30, 2021			As of December 31, 2020
Exercise price	$	11.50		$	11.50

Term		5.14			5.25
Risk-free rate		0.89	%		0.40	%

The following table presents the changes in the fair value of warrant liabilities:

	Private Placement Warrants

Change in fair value		(9,025,000	)
Fair value, June 30, 2021	$	14,155,000

Note 7 — Fair Value Measurements

As of December 31, 2020 and 2019, the carrying values of cash, prepaid expenses, and accounts payable approximate their fair values due to the short-term nature of the instruments. As of December 31, 2020, the Company’s portfolio of investments held in Trust Account is comprised entirely of investments in money market funds that invest in U.S. government securities.

The following table presents our fair value hierarchy for liabilities measured at fair value on a recurring basis for each reporting period:

Stockholders' Equity Note [Abstract]

Shareholders' Equity

Note 6 — Shareholders’ Equity

Preference Shares

The Company is authorized to issue 1,000,000 preference shares with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of June 30, 2021 and December 31, 2020, there were no preference shares issued or outstanding.

Ordinary Shares

Class A Ordinary Shares — The Company is authorized to issue 300,000,000 Class A ordinary shares with a par value of $0.0001 per share. As of June 30, 2021 and December 31, 2020, there were 30,000,000 Class A ordinary shares outstanding, including 30,000,000 and 22,726,721 Class A ordinary shares subject to possible redemption classified as temporary equity in the accompanying balance sheets, respectively.

Holders of the Class A ordinary shares and holders of the Class B ordinary shares will vote together as a single class on all matters submitted to a vote of the Company’s shareholders except as required by law.

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of the initial Business Combination at a ratio such that the number of Class A ordinary shares issuable upon conversion of all Founder Shares will equal, in the aggregate, on an as-converted basis, 20% of the sum of (i) the total number of ordinary shares issued and outstanding upon completion of the Initial Public Offering, plus (ii) the total number of Class A ordinary shares issued or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of the initial Business Combination, excluding any Class A ordinary shares or equity-linked securities exercisable for or convertible into Class A ordinary shares issued, or to be issued, to any seller in the initial Business Combination and any Private Placement Warrants issued to the Sponsor upon conversion of Working Capital Loans. Any conversion of Class B ordinary shares will take effect as a compulsory redemption of Class B ordinary shares and an issuance of Class A ordinary shares as a matter of Cayman Islands law. In no event will the Class B ordinary shares convert into Class A ordinary shares at a rate of less than one-to-one.

Note 8 — Shareholders’ Equity

Preference Shares

The Company is authorized to issue 1,000,000 preference shares with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of December 31, 2020 and December 31, 2019, there were no preference shares issued or outstanding.

Ordinary Shares

Class A Ordinary Shares — The Company is authorized to issue 300,000,000 Class A ordinary shares with a par value of $0.0001 per share. As of December 31, 2020 and December 31, 2019, there were 30,000,000 and no Class A ordinary shares outstanding, including 28,419,721 and no Class A ordinary shares subject to possible redemption classified as temporary equity in the accompanying balance sheets, respectively.

Class B Ordinary Shares — The Company is authorized to issue 30,000,000 Class B ordinary shares with a par value of $0.0001 per share. Holders of Class B ordinary shares are entitled to one vote for each share. As of December 31, 2019, there were 8,625,000 Class B ordinary shares outstanding. Of these, an aggregate of up to 1,125,000 shares were subject to forfeiture to the Company by the Sponsor for no consideration to the extent that the underwriter’s over-allotment option was not exercised in full or in part, so that the Initial Shareholders will collectively own 20% of the Company’s issued and outstanding ordinary shares after the Initial Public Offering. The over-allotment option expired in June 2020; thus, an aggregate of 1,125,000 Class B ordinary shares was forfeited accordingly. As of December 31, 2020, there were 7,500,000 Class B ordinary shares outstanding.

Warrants

Public Warrants may only be exercised for a whole number of shares. No fractional Public Warrants will be issued upon separation of the Units and only whole Public Warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination or (b) 12 months from the closing of the Initial Public Offering; provided in each case that the Company has an effective registration statement under the Securities Act covering the issuance of the Class A ordinary shares issuable upon exercise of the warrants and a current prospectus relating to them is available and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder (or the Company permits holders to exercise their warrants on a cashless basis under certain circumstances). The Company has agreed that as soon as practicable, but in no event later than 20 business days, after the closing of a Business Combination, the Company will use its commercially reasonable efforts to file with the SEC a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants and to maintain a current prospectus relating to those Class A ordinary shares until the warrants expire or are redeemed. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the 60th day after the closing of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. The Public Warrants will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation.

Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share. If (x) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per ordinary share (with such issue price or effective issue price to be determined in good faith by the Company and, (i) in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance, and (ii) without taking into account the transfer of Founder Shares or Private Placement Warrants (including if such transfer is effectuated as a surrender to us and subsequent reissuance by the Company) by the Sponsor in connection with such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Company’s Class A ordinary shares during the 20-trading day period starting on the trading day prior to the day on which the Company consummates its initial Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price discussed below will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price.

The Company may call the Public Warrants for redemption (except with respect to the Private Placement Warrants):

• in whole and not in part;

• at a price of $0.01 per warrant;

• upon a minimum of 30 days’ prior written notice of redemption, and

• if, and only if, the closing price of the Company’s Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders.

If the Company calls the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement.

The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the ordinary shares issuable upon exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be non-redeemable so long as they are held by the initial purchasers or such purchasers’ permitted transferees. If the Private Placement Warrants are held by someone other than the Initial Shareholders or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

Additionally, in no event will the Company be required to net cash settle any Warrants. If the Company is unable to complete the initial Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

- Definition

The entire disclosure for shareholders' equity comprised of portions attributable to the parent entity and noncontrolling interest, including other comprehensive income. Includes, but is not limited to, balances of common stock, preferred stock, additional paid-in capital, other capital and retained earnings, accumulated balance for each classification of other comprehensive income and amount of comprehensive income.

Note 9 — Subsequent Events

The Company has evaluated subsequent events and transactions that occurred after the balance sheet date up to the date that the financial statements were issued. Based upon this review, other than as described in these financial statements, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements.

Note 9 — Subsequent Events

Proposed Business Combination and Related Transactions

Pursuant to the Business Combination Agreement, the Company will migrate to and be continued as a company in British Columbia, Canada (the “SOAC Continuance”). Following the SOAC Continuance, pursuant to a plan of arrangement (the “Plan of Arrangement”) under the Business Corporations Act (British Columbia), (i) the Company will acquire all of the issued and outstanding shares in the capital of DeepGreen (the “DeepGreen Shares”) from DeepGreen shareholders in exchange for the Company’s common shares (as defined below) and Company Earnout Shares (as defined below) (the “Share Exchange”), (ii) DeepGreen will become a wholly-owned subsidiary of the Company, and (iii) DeepGreen and NewCo Sub will amalgamate to continue as one unlimited liability company, in each case, on the terms and subject to the conditions set forth in the Business Combination Agreement and the Plan of Arrangement and in accordance with the provisions of applicable law.

Each option to purchase common shares in the capital of the Company (the “DeepGreen Options”) will become an option to purchase SOAC Common Shares and Company Earnout Shares on the same terms and conditions (including applicable vesting, expiration and forfeiture provisions) that applied to the corresponding DeepGreen Options immediately prior to closing of the Business Combination.

The Proposed Business Combination is expected to close in the second quarter of 2021, following the receipt of the required approval by the Company’s shareholders and the fulfillment of other conditions.

The shareholders and the optionholders of DeepGreen will be entitled to receive, in exchange for their DeepGreen Shares or DeepGreen Options, as applicable, an aggregate of (i) will receive shares in the capital of the Company or comparable equity awards that are settled or are exercisable for shares in the capital of the Company, as applicable, based on an implied DeepGreen equity value of $2.25 billion after giving effect to the SOAC Continuance (the “SOAC Common Shares”), (ii) 5,000,000 Class A Special Shares, (iii) 10,000,000 Class B Special Shares, (iv) 10,000,000 Class C Special Shares, (v) 20,000,000 Class D Special Shares, (vi) 20,000,000 Class E Special Shares, (vii) 20,000,000 Class F Special Shares, (viii) 25,000,000 Class G Special Shares and (ix) 25,000,000 Class H Special Shares, in each case, in the capital of SOAC (collectively, the “Company Earnout Shares”), or, as applicable, options to purchase such SOAC Common Shares and Company Earnout Shares.

Concurrently with the execution of the Business Combination Agreement, the Company entered into subscription agreements (the “Subscription Agreements”) with certain institutional and accredited investors, pursuant to which such investors agreed to subscribe for and purchase, and the Company agreed to issue and sell to such investors, substantially concurrently with the Closing (as defined in the Business Combination Agreement), an aggregate of 33,030,000 shares of SOAC Common Shares for $10.00 per share, for aggregate gross proceeds of $330,300,000 (the “PIPE Financing”). The closing of the PIPE Financing is contingent upon, among other things, the substantially concurrent consummation of the Business Combination. The Subscription Agreements provide that the Company will grant the investors in the PIPE Financing certain customary registration rights. The PIPE Financing is contingent upon, among other things, the substantially concurrent closing of the Business Combination.

Subsequent Events

12. Subsequent Events

In preparing the consolidated financial statements for the period ended June 30, 2021, the Company has evaluated subsequent events for recognition and disclosure through September 9, 2021, the date that these unaudited consolidated financial statements and accompanying notes were available for issuance.

On September 9, 2021, the Company completed the Business Combination with SOAC. The Business Combination was approved by SOAC’s shareholders at its extraordinary general meeting held on September 3, 2021. The transaction resulted in the combined company being renamed “TMC the metals company Inc.” and the combined company’s common shares and warrants to purchase common shares commenced trading on the NASDAQ on September 10, 2021 under the symbols “TMC” and “TMCWW,” respectively. As a result of the Business Combination, the Company received gross proceeds of approximately $137.5 million. Additional discussion about the Business Combination is provided in Item 2.01 of this Current Report on Form 8-K.

The Business Combination will be accounted for as a reverse recapitalization. The Company will be deemed the accounting predecessor and the combined entity will be the successor SEC registrant. As such, the Company’s financial statements for previous periods will be disclosed in the registrant’s future periodic reports filed with the SEC. Under this method of accounting, SOAC will be treated as the acquired company for financial statement reporting purposes.

16. Subsequent Events

In preparing the consolidated financial statements for the year ended December 31, 2020, the Company has evaluated subsequent events for recognition and disclosure through March 26, 2021, the date that these consolidated financial statements and accompanying notes were available for issuance.

1. On January 27, 2021, the Company signed a Letter of Intent (“LOI”) with Sustainable Opportunities Acquisition Corporation (“SOAC”), a NYSE listed Special Purpose Acquisition Corporation (“SPAC”), for a proposed business combination (“Business Combination”) in which SOAC would merge with DeepGreen pursuant to a proposed combination and relisting on NASDAQ. The new entity will be renamed The Metals Company in connection with the merger.

The Parties to the LOI have granted mutual exclusivity of 30 days to complete transaction due diligence and commence marketing to potential PIPE investors in connection with the transaction. SOAC currently holds approximately $300 million in treasury and the parties expect to raise an additional $330 million in PIPE funds. The proposed structure contemplates that on completion, DeepGreen shareholders would hold approximately 77% of The Metals Company, PIPE Investors approximately11% and SOAC investors approximately 10% and SOAC Sponsors approximately 2%. Certain DeepGreen Shareholders would be subject to a customary lock up arrangement for a period of up to 12 months or once certain trading conditions of The Metals Company have been met.

In addition to the share-based consideration in SOAC, each DeepGreen shareholder would receive incentive shares (the “Incentive Shares”). These Incentive Shares would vest and be issued to each DeepGreen Shareholder when The Metals Company’s share price trades above certain thresholds as follows:


Share price ($)	15	25	35	50	75	100	150	200
Incentive Shares (mil)	5	10	10	20	20	20	25	25

Similarly, in connection with the transaction, the SOAC sponsors will also be entitled to additional 0.5 million Incentive Shares when the share price of The Metals Company trades at $50.00.

In connection with the proposal, SOAC, a Cayman entity, proposes to redomicile to Canada. Accordingly, DeepGreen would amalgamate and remain a Canadian entity, being listed in the United States on the NASDAQ.

The Company and SOAC finalized the Business Combination agreement on March 4, 2021. The parties are currently evaluating the accounting impact of the transaction.

2. The Company made a payment of $1,250,000 on January 26, 2021, and $440,000 on February 26, 2021 to Deep Sea in connection with the deferred consideration related to TOML Acquisition (Note 3). The Company has committed to making the remaining payment of $1,750,000 by June 30, 2021.

3. On January 29, 2021, 1,800,000 incentive stock options, with exercise price of $0.75 per share, were exercised by the Company’s directors and officers for total proceeds of $1,350,000.

4. On February 17, 2021, the Company granted a total of 490,666 incentive stock options to certain directors and non-employees. These options have an exercise price of between $0.25 per share and $0.75 per share, vested immediately upon grant, and expire between February 17, 2026 and February 26, 2026.

5. On February 26, 2021, the Company granted a total of 40,400 incentive stock options to a consultant. These options have an exercise price between $0.25 per share, vested immediately upon grant, and expire on February 26, 2026.

6. During February 2021, the Company raised a total of $26 million through convertible debentures financing. The convertible debentures bear interest at the rate of 7.0% per annum, compounded annually, with maturity date that is 24 months from the date of the financing. The debentures can be converted into shares of the Company at anytime at the conversion price of $10 per share. Unless any interest is converted prior to the maturity date, all accrued and unpaid interest shall be payable at the maturity date in common shares of the Company at a conversion price of $10 per share.

In the event that the Company completes a SPAC transaction or a change of control transaction at any time prior to the maturity date, the debenture value will be automatically converted into the common shares at the conversion price immediately prior to the SPAC or change of control transaction. If the debentures, or any portion thereof, is not converted by the holder upon the earlier of the maturity date or the completion of the SPAC of change of control transaction, the outstanding debenture value will automatically convert into the common shares of the Company at the conversion price of $10 per share.

On February 18, 2021, debentures totalling $500,000 were converted to 50,000 common shares of the Company.

7. On March 1, 2021, the Company issued 3,666,267 Common Shares to Maersk to settle the invoiced amount of $4,582,834 with respect to the use of the marine vessel. Of the total invoice amount, $4,471,595 pertained to the marine cruises undertaken during the year ended December 31, 2020.

On March 4, 2021, the agreement with Maersk was amended whereby all future costs pertaining to the use of the marine vessel would be paid in cash rather than through issuance of the Common Shares of the Company. The amended agreement is in place until early 2022, at which point the parties will finalize the potential offshore engagement beyond 2022.

8. On March 4, 2021, the Company granted 4,973,237 incentive stock options to certain employees, directors and consultants under the Company’s short-term incentive payment plan (the “STIP”), as well as 8,450,000 incentive stock options to the same individuals under its long-term incentive plan (the “LTIP”).

The stock options granted under the STIP expire on June 1, 2028, have and exercise prices ranging between $0.75 per share and $3.60 per share, and have vesting periods to a maximum of three years.

The stock options granted under the LTIP have an exercise price of $0.75 per share and expire on June 1, 2028. These options vest based on performance conditions as follows: 25% when the Company’s market capitalization equals $3 billion, 35% when the Company’s market capitalization equals $6 billion, 20% upon the date the ISA grants an exploitation contract to the Company, and 20% upon the commencement of commercial production following the grant of the exploitation contract.

9. On March 4, 2021, DeepGreen entered into an amended agreement with Allseas (the “Amendment # 3”) whereby, upon successful completion of the Business Combination, instead of issuing 10 million Common Shares to Allseas in connection with the PMTS, DeepGreen issued to Allseas a warrant to acquire 10 million DeepGreen Common Shares at a nominal value (the “Allseas Warrant”). The Allseas Warrant will vest and become exercisable upon successful completion of the PMTS and will expire on September 30, 2026. There are vesting conditions associated with the Allseas Warrant whereby a maximum of 10 million DeepGreen Common Shares would be issued if the PMTS is completed by September 30, 2023, gradually decreasing to 5 million DeepGreen Common Shares if PMTS is completed after September 30, 2025.

The Allseas Warrant will be assumed by SOAC at the closing of the Business Combination to become a warrant to purchase The Metals Company (“TMC”) common shares, adjusted for the exchange ratio for the transaction. If the market price of the TMC common shares on June 1, 2022 is higher than $15 per share (as adjusted based on the exchange ratio for the closing of the Business Combination), the aggregate value of the shares underlying the warrant above $150 million as at June 1, 2022 will automatically become a commercial credit from Allseas to TMC equal to the excess value. This commercial credit will be effective on the vesting date of the Allseas Warrant and the Company will be able to exchange this excess value for any future goods and services from Allseas under the nodule collection and shipping contract for one year after commercial production.

The cash payment of $30 million in the original agreement was also amended to be paid as follows, provided that the Business Combination is completed:

• $10 million on June 30, 2021 with Allseas providing confirmation of placing an order of certain equipment and demonstrating certain progress on construction of the collector vehicle;

• $10 million on the later of (i) January 1, 2022, and (ii) confirmation of successful collection of the North Sea test; and

• $10 million upon successful completion of the PMTS.

The Amendment # 3 is not effective until the successful completion of the Business Combination. If the Business Combination is not consummated, the Allseas Warrant shall be cancelled and the rights and obligations set forth in Amendment # 3 shall not take effect and the rights and obligations under the arrangements with Allseas as in effect prior to the execution of Amendment # 3 shall continue in effect unless otherwise amended.

Nature of Operations

1. Nature of Operations

DeepGreen Metals Inc. (“DeepGreen” or the “Company”) is incorporated under the laws of the Province of British Columbia, Canada. The Company’s corporate office, registered address and records office is located at 10th floor, 595 Howe Street, Vancouver, British Columbia, Canada, V6C 2T5.

DeepGreen is a Canadian company engaged in seafloor mineral exploration in the Clarion Clipperton Zone (the “CCZ”), approximately 2,000 km west of Mexico in the East Pacific Ocean, a region that hosts high grade polymetallic nodules containing manganese, nickel, copper and cobalt. DeepGreen is considered to have mining operations and mining properties in accordance with US Securities and Exchange Commission (“SEC”) regulations. The Company is also developing technology for onshore processing of polymetallic nodules as well as working with Allseas Group S.A (“Allseas”) to develop a system to collect, lift and transport nodules to shore. DeepGreen’s wholly-owned subsidiary, Nauru Ocean Resources Inc. (“NORI”), sponsored by the Republic of Nauru, was granted an exploration license by the International Seabed Authority (the “ISA”) in July 2011 granting NORI exclusive rights to explore for polymetallic nodules in a region of the CCZ covering 74,830 km2 allocated to the Republic of Nauru (“NORI Area”). Similarly, through Marawa Research and Exploration Limited (“Marawa”), DeepGreen was equally granted rights by the ISA to polymetallic nodules exploration in an area of 74,990 km2 in the CCZ allocated to the Republic of Kiribati. The Company entered into an option agreement with Marawa to purchase such tenements granted to exclusively collect nodules from this area in return for a royalty payable to Marawa. During the year ended December 31, 2020, DeepGreen acquired Tonga Offshore Mining Limited (“TOML”), which was granted an exploration license by the ISA in January 2012 and has exclusive rights to explore for polymetallic nodules covering 74,713 km2 of the CCZ under the supervision of the Kingdom of Tonga.

On March 4, 2021, the Company and Sustainable Opportunities Acquisition Corporation (“SOAC”), a NYSE listed Special Purpose Acquisition Corporation (“SPAC”), entered into a business combination agreement (the “BCA”) in which SOAC would merge with DeepGreen pursuant to a proposed combination and relist on the NASDAQ (the “Business Combination”). The new entity will be renamed TMC the metals company Inc. (“TMC”) in connection with the Business Combination.

In addition to the share-based consideration in SOAC, each DeepGreen shareholder would receive special shares (the “DeepGreen Earnout Shares”). These DeepGreen Earnout Shares would vest and be issued to each DeepGreen shareholder when TMC’s share price trades above certain thresholds as follows:


Share price ($)	15	25	35	50	75	100	150	200
DeepGreen Earnout Shares (mil)	5	10	10	20	20	20	25	25

Similarly, in connection with the transaction, the SOAC sponsors will also be entitled to additional 0.5 million special shares when the share price of TMC trades at $50.00.

The Business Combination closed on September 9, 2021 (refer to note 12 for details). In connection with the Business Combination, SOAC, a Cayman entity, redomiciled to Canada. Accordingly, DeepGreen remains a Canadian entity and became a wholly-owned subsidiary of TMC, which is listed in the United States on the NASDAQ.

commercial and technical feasibility of seafloor polymetallic nodule mining and processing, metal prices, and regulatory approval for mining and environmental permitting. The outcome of these matters cannot presently be determined because they are contingent on future events.

Despite the expected completion of the Business Combination, the Company will require additional funding in the future for administration and to execute its exploration and development plans. While the Company has been successful in obtaining its required funding in the past, there is no assurance that such financing will continue to be available. Factors that could affect the availability of financing include, among other things, progress and exploration results, the state of international debt and equity markets, investor perceptions and expectations, and the global financial and metals markets.

Since March 2020, several measures have been implemented by the governments in Canada, the United States, Australia, and the rest of the world in the form of office closures and limiting the movement of personnel in response to the increased impact from the novel coronavirus (“COVID-19”). While the impact of COVID-19 is expected to be temporary, the current circumstances are dynamic and the impact on our business operations, exploration and development plans, results of operations, financial position, and cash flows cannot be reasonably estimated at this time.

1. Nature of Operations

DeepGreen is a Canadian company engaged in seafloor mineral exploration in the Clarion Clipperton Zone (the “Clarion Clipperton Zone”), approximately 2,000 km west of Mexico in the East Pacific Ocean, a region that hosts high grade polymetallic nodules containing manganese, nickel, copper and cobalt. DeepGreen is considered to have mining operations and mining properties in accordance with SEC regulations. The Company is also developing technology for onshore processing of polymetallic nodules as well as working with Allseas Group S.A (“Allseas”) to develop a system to collect, lift and transport nodules to shore. DeepGreen’s subsidiary, Nauru Ocean Resources Inc., (“NORI”) was granted an exploration license by the International Seabed Authority (“ISA”) in July 2011 and has exclusive rights to explore for polymetallic nodules covering 74,830 km2 in the Clarion Clipperton Zone (“NORI Area”). The Company also has an agreement with Marawa Research and Exploration Ltd (“Marawa”) with respect to polymetallic nodules in an exploration area of 74,990 km2 in the Clarion Clipperton Zone granted to Marawa by the ISA where DeepGreen can purchase such tenements granted to Marawa or exclusively collect nodules from this area (the “Marawa Area”) in return for a royalty payable to Marawa. During the year ended December 31, 2020, the Company acquired Tonga Offshore Mining Ltd. (“TOML”) (Note 3). TOML was granted an exploration license by the ISA in January 2012 and has exclusive rights to explore for polymetallic nodules covering 74,713 km2 of the Clarion Clipperton Zone.

The recovery of the Company’s exploration licenses and attainment of profitable operations is dependent upon many factors including, among other things: financing being arranged by the Company to continue operations, explore and develop the ocean floor for the extraction of polymetallic nodules as well as develop processing technology for the treatment of polymetallic nodules, the establishment of a mineable resource, the commercial and technical feasibility of seafloor polymetallic nodule mining and processing, metal prices, and regulatory approval for mining and environmental permitting. The outcome of these matters cannot presently be determined because they are contingent on future events.

The Company will require additional funding in the future, for administration and to execute its exploration and development plans. While the Company has been successful in obtaining its required funding in the past, there is no assurance that such financing will continue to be available. Factors that could affect the availability of financing include, among other things, progress and exploration results, the state of international debt and equity markets, investor perceptions and expectations, and the global financial and metals markets.

Since March 2020, several measures have been implemented by the governments in Canada, the United States, Australia, and the rest of the world in the form of office closures and limiting the movement of personals in response to the increased impact from the novel coronavirus (“COVID-19”). While the impact of COVID-19 is expected to be temporary, the current circumstances are dynamic and the impact on our business operations cannot be reasonably estimated at this time. We anticipate this could have an adverse impact on our exploration plans, results of operations, financial position, and cash flows.

Significant Accounting Policies

The Company’s accounting policies specific to significant financial statement line items are included below. All accounting policies have been consistently applied to all years presented.

i. Foreign Currencies

The functional currency is the currency of the primary economic environment in which the entity operates. The functional currency of the Company and all its subsidiaries is the US Dollar, except for NEAT and NHEF, whose functional currency is the Australian Dollar.

At the end of each reporting period, monetary assets and liabilities that are denominated in foreign currencies are translated into the functional currency at the rates prevailing at that date. Non-monetary assets and liabilities carried at fair value that are denominated in foreign currencies are translated at rates prevailing at the date when the fair value was determined. All gains and losses on translation of these foreign currency transactions are included in the statements of loss and comprehensive loss. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated.

For consolidation purposes, the assets and liabilities of entities with functional currencies other than the US dollar are translated at the period end rates of exchange, and the results of their operations are translated at average rates of exchange for the period. The resulting changes are recognized in accumulated other comprehensive loss within equity as currency translation differences.

ii. Loss Per Share

Basic loss per share is computed by dividing loss available to common shareholders by the weighted average number of common shares outstanding during the year. The computation of diluted loss per share assumes the conversion, exercise or contingent issuance of securities only when such conversion, exercise or issuance would have a dilutive effect on the loss per share. The dilutive effect of convertible securities is reflected in the diluted loss per share by application of the “if converted” method. The dilutive effect of outstanding options and their equivalents is reflected in the diluted loss per share by application of the treasury stock method.

iii. Financial Instruments

Financial assets and liabilities are recognized when the Company becomes a party to the contractual provisions of the instrument. Financial assets are derecognized when the rights to receive cash flows from the assets have expired, or have been transferred, and the Company has transferred substantially all risks and rewards of ownership. A financial liability is derecognized when the obligation specified in the contract is discharged, cancelled, or expires.

The Company’s financial instruments consists of cash and cash equivalents, accounts payable and accrued inabilities, and deferred acquisition costs all of which are recorded at amortized cost.

iv. Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and term deposits with a remaining term to maturity at acquisition of three months or less.

v. Equipment

Equipment are stated at cost less accumulated depreciation and accumulated impairment losses. Cost includes expenditures that are directly attributable to the acquisition of the asset. Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, when it is probable that future economic benefits from such assets will flow to the Company and the cost of such assets can be measured reliably. The carrying amount of an asset is derecognized when it is replaced or taken out of service. Repairs and maintenance costs are charged to the statement of loss and comprehensive loss during the period they are incurred.

The major categories of equipment are amortized on declining balance basis as follows:

Exploration and other equipment		30	%
Office equipment		30	%

The Company allocates the amount initially recognized to each asset’s significant components and depreciates each component separately. Amortization methods and useful life of the assets are reviewed at each financial period end and adjusted on a prospective basis, if required.

Gains and losses on disposals of equipment are determined by comparing the proceeds with the carrying amount of the asset and are included in the statement of loss and comprehensive loss.

vi. Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities in the consolidated balance sheet. The Company does not have any finance leases.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of such leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The lease terms may include options to extend or terminate the lease and when it is reasonably certain that we will exercise that option.

The Company elected to apply the short-term lease recognition exemption to all of its lease arrangements and recorded an expense of $116,760 (2019 – $85,479) for lease payments during the year ended December 31, 2020. Such lease expense is disclosed under office and sundry line item within the statement of loss and comprehensive loss and forms part of cash flow from operating activities.

vii. Exploration Licenses

The Company is in the exploration stage with respect to its investment in mineral licenses and follows the practice of capitalizing costs relating to the acquisition of such mineral licenses.

Exploration Expenses

The Company expenses all costs relating to exploration for and development of mineral claims. Such exploration and development costs include, but are not limited to, claims management, geological, geochemical and geophysical studies, process development. The mineral licenses would be charged to operations on a unit-of-production method based on proven and probable reserves should commercial production commence in the future.

viii. Stock-based compensation

Stock-based compensation is measured at the grant date based on the fair value of the award and is recognized over the requisite service period. Stock-based compensation costs are charged to exploration expenses or common share options-based payments in the income statement. The Company recognizes forfeiture of any awards as they occur. The Company records stock-based compensation from the issuance of the stock options with service-based conditions using the accelerated attribution method.

For stock options issued with performance conditions related to financing activities, the Company recognizes the costs when the specific performance targets are achieved using the accelerated attribution method. When these costs relate to equity financing, they are netted against share capital as a share issuance cost

The Company at times grants common shares or stock options in lieu of cash to certain vendors for their services to the Company. The Company recognizes the associated cost in the same period and manner as if the Company paid cash for the services provided.

ix. Income Taxes

The Company accounts for income taxes under the asset and liability method which requires the recognition of deferred income tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities. The Company provides a valuation allowance on deferred tax assets unless it is more likely than not that such assets will be realized.

Significant Accounting Estimates and Judgments

The preparation of financial statements in accordance with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, income and expenses. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis of making the judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Significant management judgments and estimates were applied to the following areas:

i. TOML Acquisition

In March 2020, the Company completed the TOML Acquisition (Note 3) and applied guidance from U.S. GAAP Accounting Standard Coding (“ASC”) 805 to understand the accounting treatment regarding this acquisition and make necessary judgements.

ASC 805 defines a business as inputs and processes, when applied to the inputs, resulting in the creation of outputs. The key input acquired in connection with the TOML Acquisition is the TOML Exploration License and the related intellectual property. TOML Exploration License is in the development stage and therefore does not produce outputs. ASC 805 requires that where there is no output, there must be both an input and substantive process which must include an organized workforce with the necessary skills, experience, and knowledge to develop and convert the inputs into outputs, for a group of assets to be considered a business. An organized workforce was not included in the TOML Acquisition and therefore the Company’s management deemed that the TOML Acquisition was not a business acquisition and only an acquisition of a group of assets.

The Company’s position is supported by ASC 805’s guidance that if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not considered a business. The value of the TOML is considered to be primarily in the TOML Exploration License.

Management also determined that other assets acquired (which included other intangible assets such as patents and trademarks) were connected to the TOML Exploration License and would not hold value by themselves. The value of the total cost was therefore capitalized into one line item on the Company’s balance sheet, the Exploration licenses.

ii. Valuation of common share-based payments

DeepGreen recognizes the cost of share-based awards granted to employees, non-employees and directors based on the estimated grant-date fair value of the awards. DeepGreen determines the fair value of stock options using the Black-Scholes option pricing model, which is impacted by the following assumptions:

• Fair Value of Common Stock on the Date of the Grant — DeepGreen uses the price of the most recent private placements to assess the value of its shares on the date of the grant of incentive stock options.

• Expected Term — DeepGreen uses the term of the award when calculating the expected term due to insufficient historical exercise data.

• Expected Volatility — As DeepGreen’s shares are not actively traded, the volatility is based on a benchmark of comparable companies within the mining industry.

• Expected Dividend Yield — The dividend rate used is zero as DeepGreen has never paid any cash dividends on common stock and does not anticipate doing so during the expected life of the stock options.

• Risk-Free Interest Rate — The interest rates used are based on the implied yield available on Canadian Treasury zero-coupon issues with an equivalent remaining term equal to the expected life of the award.

Changes in these assumptions used to determine the fair value of the common share incentive stock options, including the vesting timeline of granted stock options, could have a material impact on the Company’s loss and comprehensive loss.

DeepGreen determines the fair value of common shares issued for services based on the most recent private placements.

Recently Adopted Accounting Guidance

i. Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize all leases on the balance sheet, including operating leases, unless the lease is a short-term lease. ASU 2016-02 also requires additional disclosures regarding leasing arrangements. ASU 2016-02 became effective for the Company as of January 1, 2019. At January 1, 2019, the Company had an office lease agreement expiring September 12, 2020 which was later extended to September 12, 2022. The Company elected the short-term lease recognition exemption and, as a result, no right of use assets or lease liabilities were recognized as of January 1, 2019.

ii. Stock Based Compensation

In June 2018, the FASB issued ASU 2018-07, Stock Compensation (Topic 718), which updates the accounting provisions for nonemployee share-based payments to be measured at fair value as of the grant date. ASU 2018-07 became effective for the Company as of January 1, 2019.

Recent Accounting Guidance Not Yet Adopted

i. Accounting for Income Taxes

In December 2019, the FASB issued a new standard to simplify the accounting for income taxes. The guidance eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences related to changes in ownership of equity method investments and foreign subsidiaries. The guidance also simplifies aspects of accounting for franchise taxes and enacted changes in tax laws or rates, and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The standard will be effective for the Company beginning Jan. 1, 2022, with early adoption permitted. The Company is currently evaluating the impact of this standard in the consolidated financial statements, including accounting policies, processes, and systems.

TOML Acquisition

3. TOML Acquisition

On March 31, 2020, the Company entered into an acquisition agreement (“TOML Acquisition”) to acquire the nodules business unit of Tonga Offshore Mining Ltd (“TOML”) and other entities in the group (the “TOML Group”), from Deep Sea Mining Finance Ltd. (“Deep Sea Mining”). Total purchase price of the TOML Acquisition, before transaction costs, was $32,000,000. TOML holds an ISA Exploration Contract in the CCZ (“TOML Exploration Contract”). The TOML Acquisition includes the exclusive rights held by TOML to explore for polymetallic nodules in an area covering 74,713 km2, a priority right to apply for an exploitation contract to mine polymetallic nodules in the same area, and some exploration related equipment. The TOML group also holds various patents and an application right with respect to a prospecting exploration license in the Republic of Kiribati.

The purchase price of $32,000,000 was settled through initial cash payments of $500,000 in two tranches of $250,000 each (paid on March 31, 2020 and May 31, 2020, respectively), issuance of 7,777,777 common shares of the Company, $60,000 payment to ISA on behalf of Deep Sea Mining and deferred consideration of $3.44 million to be paid on January 31, 2021. As long as the deferred consideration remains outstanding, it is secured by the shares of the TOML Group. The Common Share consideration paid by the Company was valued at $3.60 per share, based on the recent private placements completed by the Company, for a total of $28 million.

The Company had the option of settling the deferred consideration in either cash or Common Shares of the Company at its sole discretion. During January 2021, the arrangement with Deep Sea Mining was amended to pay the entire deferred consideration with cash in tranches by June 30, 2021.

The Company incurred legal and regulatory fees to complete the acquisition, totalling $47,375.

The Company determined that the value of TOML Acquisition was substantially concentrated in the TOML Exploration Contract and therefore considered this to be an acquisition of a group of connected assets rather than an acquisition of business. Consequently, the total cost of the transaction was primarily allocated to exploration licenses.

The net assets acquired as part of the TOML acquisition were as follows:

Net Assets acquired	$
Cash payment	560,000
Common shares issued for TOML acquisition (7,777,777 @ $3.60)	27,999,997

__________

(1) A deferred tax liability of $10,675,366 was recognized by the Company on acquisition during the year ended December 31, 2020 related to the difference between the book value and the tax basis of the TOML exploration license.

The Company made payments to Deep Sea Mining as follow in connection with the deferred consideration: $1,250,000 on January 26, 2021, $440,000 on February 26, 2021, $500,000 on March 31, 2021, $500,000 on April 30, 2021, $500,000 on May 31, 2021, and $250,000 on June 30, 2021. As at June 30, 2021, the Company has no further deferred consideration outstanding for this acquisition.

3. TOML Acquisition

On March 31, 2020, the Company entered into an acquisition agreement (“TOML Acquisition”) to acquire the nodules business unit from Deep Sea Mining Finance Ltd. (“Deep Sea Mining”). As part of this acquisition the Company acquired TOML, Koloa Moana, Offshore Minerals, TOML Singapore, TOML Hold 1 & TOML Hold 2 (together, the “TOML Group”), for a total purchase price, before transaction costs, of $32,000,000. TOML holds an ISA Exploration Contract in the Clarion Clipperton Zone of the East Pacific Ocean (“TOML Exploration Contract”). The TOML Acquisition includes the exclusive rights held by TOML to explore for polymetallic nodules in an area covering 74,713 km2, a priority right to apply for an exploitation contract to mine polymetallic nodules in the same area, and some exploration related equipment. The TOML group also holds various patents and an application right with respect to a prospecting exploration license in the Republic of Kiribati.

The purchase price of $32 million was settled through initial cash payments of $500,000 in two tranches of $250,000 each (paid), issuance of 7,777,777 common shares of the Company, $60,000 payment to ISA on behalf of Deep Sea Mining and deferred consideration of $3.44 million to be paid on January 31, 2021. As long as the deferred consideration remains outstanding, it is secured by the shares of the TOML Group. The Common Share consideration paid by the Company was valued at $3.60 per share based on the recent private placements completed by the Company, for a total of $28 million.

The Company had the option of settling the deferred consideration in either cash or Common Shares of the Company at its sole discretion. Subsequent to the year ended December 31, 2020, the arrangement with Deep Sea Mining was amended to pay the entire deferred consideration with cash in tranches by June 30, 2021 (Note 16).

The Company incurred legal and regulatory fees to complete the acquisition, totalling $47,375.

The Company determined that the value of TOML acquisition was substantially concentrated in the TOML Exploration Contract and therefore considered this to be an acquisition of a group of connected assets rather than an acquisition of business.

Significant Exploration Agreements

NORI Exploration Contract:

The Company’s wholly-owned subsidiary, NORI, was granted a polymetallic nodule exploration contract in the CCZ by the ISA on July 22, 2011. The contract was acquired for $250,000, and provides NORI with exclusive rights to explore for polymetallic nodules in an area covering 74,830 km2 for 15 years subject to complying with the exploration contract terms (Note 9) and provides NORI with the priority right to apply for an exploitation contract to mine polymetallic nodules in the same area.

NORI has a right to renounce, without penalty, the whole or part of its rights in the exploration area at any time and therefore doesn’t have a fixed commitment with relation to the NORI License (Note 9)

Marawa Agreements:

On March 17, 2012 the Company’s wholly-owned subsidiary, DeepGreen Engineering Pte. Ltd. (“DGE”), entered into an Option Agreement (the “Marawa Option Agreement”) with Marawa and the Republic of Kiribati (the “State”). This Marawa Option Agreement was amended on October 1, 2013. Under the amended Marawa Option Agreement, for an option fee of $250,000, DGE has the right to purchase tenements, as may be granted to Marawa by the ISA or any other regulatory body, for the greater of $300,000 or the value of any amounts owing to DGE by Marawa. This Marawa Option, can be exercised when a default event, as defined by the amendment agreement, occurs and anytime within 40 years after the date of execution of the Marawa Option agreement.

As at June 30, 2021, Marawa had no amounts owing to DGE under the Marawa Services Agreement (defined below) and no purchase tenements had been granted to Marawa.

On October 1, 2013, DGE entered into a services agreement (the “Marawa Services Agreement”) with Marawa and the State, which grants the Company the exclusive right to carry out all exploration and mining in the Marawa Area. Under this agreement DGE will pay to the ISA on behalf of Marawa the following dues: $47,000 annual exploration fees, the ISA royalty and taxes and the ISA exploitation application fee of $250,000. Also, DGE will ensure that the activities carried out in the Marawa Area by DGE and any other service contractor complies with the ISA regulations and any other required regulations. The Marawa Area is situated in close proximity to the 74,830 km2 NORI Area.

The Marawa Services Agreement grants DGE the right to recover any and all polymetallic nodules from the Marawa Area by paying the Republic of Kiribati a royalty per wet tonne of polymetallic nodules (adjusted for inflation from October 1, 2013 onwards).

DGE has the right to terminate the Marawa Services Agreement at its sole discretion by giving written notice to Marawa and the State, and such termination shall take effect two months following the date of the termination notice, provided that DGE shall pay to the ISA on behalf of Marawa the fees or payments legally owed to the ISA by Marawa (including the annual ISA exploration fee and ISA royalties and taxes) that are outstanding at the date of termination or that are incurred within 12 months after the date of such termination. There are no other longer-term commitments with respect to the Marawa Option and the Marawa Services Agreement.

TOML Exploration Contract:

The Company’s wholly-owned subsidiary, TOML, was granted a polymetallic nodule exploration contract in the six areas of CCZ by the ISA on Jan 11 2012. The TOML Group was acquired by the Company for $32 million from Deep Sea Mining (Note 3). TOML has the exclusive rights to explore for polymetallic nodules in an area covering 74,713 km2 for 15 years and a priority right to apply for an exploitation contract to mine polymetallic nodules in the TOML area.

Strategic Partnerships

Marine Vessel Services:

Effective March 15, 2017, the Company entered into a strategic partnership with Maersk to undertake the exploration, environmental base line and offshore testing required to support development of feasibility studies for economic production of polymetallic nodules from the CCZ. Under the agreement, Maersk provides marine vessel services and project management services, enabling DeepGreen to undertake the various marine cruises to support required prefeasibility studies. During these marine cruises DeepGreen undertook baseline studies required to complete an Environmental and Social Impact Assessment (“ESIA”), collected nodules for metallurgical test work and collected samples for resource evaluation. Up until February 5, 2021, the costs related to the marine vessel use was settled through DeepGreen Common Shares, the number of which was based on a contractual price of $1.25 per Common Share. Project management services provided by Maersk are paid in cash.

Year of Service	Invoiced amount $	Contractual Common Share Price $	# of Common Shares	Fair value of Common Shares $(1)	Cost Recognized $
2017/2018	2,565,500	1.25	2,052,400	0.75	1,539,300

__________

(1) The fair value of the Company’s Common Shares was determined based on the private placements completed around the time of Common Share issuances to Maersk, including the application of weighted average probability for the closing of the Business Combination.

(2) During the six months ended June 30, 2021, the Company issued 3,666,267 Common Shares to Maersk of which, 3,577,516 pertained to the marine vessel use during the year ended December 31, 2020. These Common Shares were recognized at their estimated fair value of $7.00 (December 31, 2020 — $3.60 per Common Share).

As at June 30, 2021, Maersk owned 17,982,123 Common Shares of the Company which constituted 10.53% of the total Common Shares outstanding. Maersk is considered a related party to the Company.

Total cost incurred to Maersk for marine campaigns during the six months ended June 30, 2021 amounted to $22,056,802 (June 30, 2020 - $15,547,941).

On March 4, 2021, the agreement with Maersk was amended whereby all costs incurred from February 5, 2021 pertaining to the use of the marine vessel would be paid in cash rather than through issuance of the Common Shares of the Company. The amended agreement is in place until early 2022, at which point the parties will finalize the potential offshore engagement beyond 2022.

As at June 30, 2021, amount payable to Maersk was $5,904,606 (December 31, 2020 - $1,829,268).

Pilot Mining Test Project

On March 29, 2019, DeepGreen and Allseas entered into a strategic alliance to conduct a Pilot Mining Test System (“PMTS”), the successful completion of which would aid DeepGreen’s application for an exploitation contract with the ISA. Under the terms of this strategic alliance, Allseas subscribed for 6,666,668 Common Shares of DeepGreen for a total of $20,000,000 in cash (received during the year ended December 31, 2019) and in consideration for a successful PMTS, DeepGreen committed to paying Allseas $30,000,000 in cash and further issuing 10,000,000 Common Shares (with a contractual price of $3.00 per share) for an additional anticipated cost of $30,000,000 to Allseas. This additional payment is contingent upon successful delivery of the PMTS. Allseas will cover all the development cost of the project and will own all intellectual property used and generated in the development of the PMTS.

Upon successful completion of the PMTS, DeepGreen and Allseas have also agreed to enter into a nodule collection and shipping agreement whereby Allseas will provide production services for the production of the first 200 million metric tonnes of polymetallic nodules on a cost plus 50% profit basis.

DeepGreen and Allseas can terminate the strategic alliance without cause at any time subject to the following:

• DeepGreen will have a call option to buy Allseas’ Common Shares in DeepGreen at the original contractual price.

• Allseas will have the right to collect 100 million metric tonnes (wet) of manganese nodule resources held by the Company by paying DeepGreen a royalty equivalent to 50% of the royalty charged by the ISA on the nodules collected.

• DeepGreen will have the right of first refusal to acquire and process all nodules collected using Allseas nodule collection and shipping systems.

Upon termination without successful commissioning of the PMTS, Allseas will be compelled to either (at Allseas’ sole election):

• Acquire an additional 10,000,000 Common Shares in DeepGreen for a consideration of $30,000,000; or

• Sell at least 6,666,667 Common Shares held in DeepGreen to the Company for total consideration of $1.

The fair value of the Company’s Common Shares at the time of the initial subscription of $20,000,000 by Allseas was determined to be $1.75 per Common Share, based on the recent private placements completed by the Company at the time. As a result, the difference between the fair value and the total proceeds of $8,333,335 (i.e. $1.25 per Common Share) was considered to be an additional initial contribution by Allseas during the year ended December 31, 2019.

During 2020, the PMTS agreement was amended and DeepGreen paid an additional $10,000,000 in cash and issued 2,777,778 common shares valued at $3.60 per share for an additional $10,000,000 to allow for higher costs that had been incurred by Allseas. The expense related to the payment and issuance of shares was offset by the additional initial contribution by Allseas received in 2019.

During the year ended December 31, 2020, Allseas subscribed for an additional 2,777,778 Common Shares for cash proceeds of $10 million.

On March 4, 2021 and June 30, 2021, DeepGreen entered into an amended agreement with Allseas (the “Amendment #3 and “Amendment #4”, respectively”) whereby, upon successful completion of the Business Combination (Note 1), instead of issuing 10 million Common Shares to Allseas in connection with the PMTS, DeepGreen issued to Allseas, on March 4, 2021, a warrant to acquire 10 million DeepGreen Common Shares at a nominal value (the “Allseas Warrant”). The Allseas Warrant will vest and become exercisable upon successful completion of the PMTS and will expire on September 30, 2026. There are vesting conditions associated with the Allseas Warrant whereby a maximum of 10 million DeepGreen Common Shares would be issued if the PMTS is completed by September 30, 2023, gradually decreasing to 5 million DeepGreen Common Shares if PMTS is completed after September 30, 2025.

The Allseas Warrant was assumed by SOAC at the closing of the Business Combination (Note 1) to become a warrant to purchase TMC common shares, adjusted for the exchange ratio for the transaction. If the market price of the TMC common shares on June 1, 2022 is higher than $15 per share (as adjusted based on the exchange ratio for the closing of the Business Combination), the aggregate value of the shares underlying the warrant above $150 million as at June 1, 2022 will automatically become a commercial credit from Allseas

to TMC equal to the excess value. This commercial credit will be effective on the vesting date of the Allseas Warrant and the Company will be able to exchange this excess value for any future goods and services from Allseas under the nodule collection and shipping contract for one year after commercial production.

The cash payment of $30 million in the original agreements was also amended to be paid as follows, provided that the Business Combination is completed:

• $10 million within 10 business days of the closing of the Business Combination, with Allseas providing confirmation of placing an order of certain equipment and demonstrating certain progress on construction of the collector vehicle;

• $10 million on the later of (i) January 1, 2022, and (ii) confirmation of successful collection of the North Sea test; and

• $10 million upon successful completion of the PMTS.

As at June 30, 2021, Allseas has successfully reached the progress milestone for the construction of the collector vehicle and confirmed the order of the required equipment.

The Amendment #3 and Amendment #4 became effective upon the completion of the Business Combination and will be payable within 10 days of the closing of the Business Combination (Note 12).

As at June 30, 2021, Allseas owned 12,222,224 Common Shares of the Company which constituted 7.15% of total Common Shares outstanding.

The Services Agreement grants DGE the right to recover any and all polymetallic nodules from the Marawa Tenement Area by paying the Republic of Kiribati a royalty per wet tonne of polymetallic nodules (adjusted for inflation from October 1, 2013 onwards).

DGE has the right to terminate the Services Agreement at its sole discretion by giving written notice to Marawa and the State, and such termination shall take effect two months following the date of the termination notice, provided that DGE shall pay to the ISA on behalf of Marawa the fees or payments legally owed to the ISA by Marawa (including the annual ISA exploration fee and ISA royalties and taxes) that are outstanding at the date of termination or that are incurred within 12 months after the date of such termination. There are no other longer term commitments with respect to the Marawa Option and the Services Agreement.

TOML Exploration Contract:

The Company’s wholly-owned subsidiary, TOML, was granted a polymetallic nodule exploration contract in the six areas of Clarion Clipperton Zone of the East Pacific Ocean by the ISA on Jan 11 2012. The TOML Group was acquired by the Company for $32 million from Deep Sea Mining (Note 3). TOML has the exclusive rights to explore for polymetallic nodules in an area covering 74,713 km2 for 15 years and a priority right to apply for an exploitation contract to mine polymetallic nodules in the TOML area.

Strategic Partnerships

Marine Vessel Services:

Effective March 15, 2017, the Company entered into a strategic partnership with Maersk Supply Service A/S (“Maersk”) to undertake the exploration, environmental base line and offshore testing required to support development of feasibility studies for economic production of polymetallic nodules from the Clarion Clipperton Zone. Under the agreement, Maersk provides marine vessel services and project management services, enabling DeepGreen to undertake the various marine cruises to support required prefeasibility studies. During these marine cruises DeepGreen undertook baseline studies required to complete an Environmental and Social Impact Assessment (“ESIA”), collected nodules for metallurgical test work and collected samples for resource evaluation. The costs related to marine vessel use is settled through DeepGreen Common Shares, the number of which is based on a contractual price of $1.25 per Common Share. Project management services provided by Maersk are paid in cash (Note 16).

Common Shares transactions with Maersk since the inception of the strategic partnership with DeepGreen are as follows:

Year of Service	Invoiced amount $	Contractual Common Share Price $	# of Common Shares	Fair value of Common Shares $(1)	Cost Recognized $
2017/2018	2,565,500	1.25	2,052,400	0.75	1,539,300

	22,366,716		17,893,373		51,767,937

____________

(1) The fair value of the Company’s Common Shares was determined based on the private placements completed around the time of Common Share issuances to Maersk.

(2) As at December 31, 2020, 3,577,516 (2019 – 1,780,632) Common Shares were yet to be issued by the Company for total value of $12,879,057 (2019 – $6,410,275) (Note 16).

As at December 31, 2020, Maersk owned 14,315,857 Common Shares of the Company which constituted 8.8% of the total Common Shares outstanding.

Total Maersk project management fees incurred during the year ended December 31, 2020 amounted to $4,407,478 (2019 – $2,820,625)., of which $1,829,268 remained outstanding as of December 31, 2020 (2019 – $437,159)

Pilot Mining Test Project

On March 29, 2019, DeepGreen and Allseas entered into a strategic alliance to conduct a Pilot Mining Test System (“PMTS”), the successful completion of which would aid DeepGreen’s application for an exploitation contract with the ISA. Under the terms of this strategic alliance, Allseas subscribed for 6,666,668 Common Shares of DeepGreen for a total of $20,000,000 in cash (received during the year ended December 31,2019) and in consideration for a successful PMTS, DeepGreen committed to paying Allseas $30,000,000 in cash and further issuing 10,000,000 Common Shares (with a contractual price of $3.00 per share) for an additional $30,000,000 to Allseas. This additional payment is contingent upon successful delivery of the PMTS. Allseas will cover all the development cost of the project and will own all intellectual property used and generated in the development of the PMTS.

DeepGreen and Allseas can terminate the strategic alliance without cause at any time subject to the following:

• DeepGreen will have a call option to buy Allseas’ Common Shares in DeepGreen at the original contractual price.

• DeepGreen will have the right of first refusal to acquire and process all nodules collected using Allseas nodule collection and shipping systems.

Upon termination without successful commissioning of the PMTS, Allseas will be compelled to either (at Allseas’ sole election):

• Acquire an additional 10,000,000 Common Shares in DeepGreen for a consideration of $30,000,000; or

• Sell at least 6,666,667 Common Shares held in DeepGreen to the Company for total consideration of $1.

The fair value of the Company’s Common Shares at the time of the initial subscription of $20,000,000 by Allseas was determined to be $1.75 per Common Share, based on the recent private placements completed by the Company at the time. As a result, the difference between the fair value and the total proceeds of $8,333,335 ($1.25 per Common Share) was considered to be an additional initial contribution by Allseas during the year ended December 31, 2019.

During the year ended December 31, 2020, Allseas subscribed for an additional 2,777,778 Common Shares for cash proceeds of $10 million. As at December 31, 2020, Allseas owned 12,222,224 Common Shares of the Company which constituted 7.5% of total Common Shares outstanding.

As at December 31, 2020, DeepGreen’s original commitment to pay Allseas $30,000,000 in cash and 10,000,000 common shares on completion of PMTS remained as the PMTS had not yet been successfully completed. The PMTS and strategic alliance agreements were further amended subsequent to the year end (Note 16).

Fiscal 2021 Activity

The Company issued 3,666,267 Common Shares to Maersk for services valued at $7.00 per share (Note 4). The Company estimated the fair value of common stock based on observable transactions in the Company’s common stock and by applying a probability-weighted approach to various outcomes. The approach involves estimates, judgments and assumptions that are highly complex and subjective. Changes in any or all of these estimates and assumptions, or the relationships between these assumptions, impact the Company’s valuation of its common stock as of each valuation date which may have a material impact on the valuation of the Company’s common stock and equity awards for accounting purposes.

During the period ended June 30, 2021, option holders exercised 3,446,821 stock options for total proceeds of $2,563,156 at a weighted average exercise price of $0.74 per share.

On February 18, 2021, convertible debentures with a principal amount of $500,000 were converted into 50,000 common shares of the Company.

9. Share Capital

Authorized and Issued

The Company has two classes of shares, being its Common Shares and Class B Preferred Shares. The authorized and issued share capital of the Company is as follows:

	Authorized	Issued and Outstanding
Common Shares	Unlimited, with no par value	163,658,134
Class B Preferred Shares	Unlimited, with no par value	440,000

Class B Preferred Shares are non-dividend earning and include voting rights similar to Common Shares. However, if any dividend is declared on Common Shares, the Company is required to concurrently declare and pay dividend on Class B Preferred Shares in the amount per share equal to the dividend per share paid on the Common shares. These Class B Preferred Shares rank ahead of Common Shares in the event of liquidation and are subject to automatic conversion to Common Shares on the basis of 1 Class B Preferred Share to 1 Common Share in the event of the Company closing a qualified Initial Public Offering of its Common Shares or if the Company undertakes a business combination, which results in the holders of the Common Shares of the Company holding securities of another entity.

The Class B Preferred Shares were issued in September 2016 at $1.25 per share. These shares had a condition that if, within 36 months after their issuance, the Company issued additional Common Shares for consideration in cash that was less than the issue price of the Class B Preferred Shares (“Subsequent Financing Securities”), each holder of a Class B Preferred Share had the right to acquire Common Shares at an issue price of $0.05 per share, for such number of Common Shares as would be required to lower the average acquisition cost of the holder’s Class B Preferred Shares and such Common Shares to the purchase price of the Subsequent Financing Securities. The Class B Preferred Shareholders exercised this right and purchased 314,285 Common Shares of the Company for total proceeds of $15,714.

As at June 30, 2021, the fair value of the Company’s Common Shares was $8.00 per share. The Company estimated the fair value of common stock based on observable transactions in the Company’s common stock and by applying a probability-weighted approach to various outcomes. The approach involves estimates, judgments and assumptions that are highly complex and subjective. Changes in any or all of these estimates and assumptions, or the relationships between these assumptions, impact the Company’s valuation of its common stock as of each valuation date which may have a material impact on the valuation of the Company’s common stock and equity awards for accounting purposes.

The aggregate intrinsic value of stock options exercised during the period ended June 30, 2021, was $25,011,412.

The total grant date fair value of STIP stock options that vested during the period ended June 30, 2021, was $25,916,669.

Activity and Valuation

On February 17, 2021, the Company granted a total of 490,666 incentive stock options to certain directors and non-employees. These options have an exercise price of between $0.25 per share and $0.75 per share, vested immediately upon grant, and expire between February 17, 2026 and February 26, 2026.

On February 26, 2021, the Company granted a total of 40,400 incentive stock options to a consultant. These options have an exercise price between $0.25 per share, vested immediately upon grant, and expire on February 26, 2026.

On March 4, 2021, the Company granted 4,973,237 incentive stock options to certain employees, directors and consultants under the Company’s STIP, as well as 8,450,000 incentive stock options to the same individuals under its LTIP.

The stock options granted under the STIP expire on June 1, 2028, have and exercise prices ranging between $0.75 per share and $10 per share, and have vesting periods to a maximum of three years.

The stock options granted under the LTIP have an exercise price of $0.75 per share and expire on June 1, 2028. The LTIP awards vest as follows:

(1) 25% when the Company’s market capitalization equals $3 billion (“Tranche 1”);

(2) 35% when the Company’s market capitalization equals $6 billion (“Tranche 2”);

(3) 20% upon the date that the ISA grants an exploitation contract to the Company (“Tranche 3”); and

(4) 20% upon the commencement of the first commercial production following the grant of the exploitation contract (“Tranche 4”).

As the vesting of Tranche 1 and Tranche 2 is based on the Company’s market capitalization of $3 billion and $6 billion, respectively, these options are determined to be market-based awards (“Market Based Awards”) for which the Company has calculated fair value and derived a service period through which to expense the related fair value. The options included in Tranche 1 and Tranche 2 had a day one fair value of $6.47 per share and $6.28 per share and derived service periods of 0.33 years and 1.41 years, respectively. The Company will expense these awards rateably over the remaining service period.

Tranche 3 and Tranche 4 of the LTIP stock options vest based on the ISA contract and the commencement of commercial production. These options are determined to be performance-based awards (“Performance Based Awards”). The Company will recognize compensation costs for the Performance Based Awards if and when the Company concludes that it is probable that the performance conditions will be achieved. As of June 30, 2021, no compensation expense related to the Performance Based Awards was recorded as the awarding of an ISA contract is outside the control of the Company. The Company will reassess the probability of the vesting of the Performance Based Awards at each reporting period and adjust the compensation cost when determined to be probable.

The fair value of the options granted under the Company’s STIP was estimated on the date of grant using the Black-Scholes option pricing model, with the following weighted average assumptions:

	2021
Expected dividend yield	0.00	%
Expected stock price volatility	89.44	%
Risk-free interest rate	0.51	%
Expected life of options (years)	3.73
Estimated per share fair value of the Company’s Common Shares	7.00

The fair value of the Market Based Awards granted under the LTIP was estimated on the date of grant using a Monte Carlo model to simulate a distribution of future stock prices with the following weighted average assumptions:

	Tranche 1 and Tranche 2
Expected dividend yield	0.00	%
Expected stock price volatility	90.98	%
Risk-free interest rate	1.25	%
Expected life of options (years)	7.25
Estimated per share fair value of the Company’s Common Shares	7.00

The fair value of the Performance Based Awards granted under the LTIP was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions:

	Tranche 3		Tranche 4
Expected dividend yield	0.00	%	0.00	%
Expected stock price volatility	91.23	%	91.23	%
Risk-free interest rate	0.82	%	0.85	%
Expected term (years)	5.22		5.35
Estimated per share fair value of the Company’s Common Shares	7.00		7.00

Changes in these assumptions could have a material impact on the Company’s loss and comprehensive loss.

During the six months ended June 30, 2021, a total of 3,446,821 stock options were exercised for total proceeds of $2,563,156 with a weighted average exercise price of $0.74 per stock option.

During the six months ended June 30, 2021, the Company recognized $47,295,676 as common share option-based payments expense in the statement of loss and comprehensive loss (June 30, 2020 – $234,115). A total of $18,684,122 related to corporate matters and was charged to the statement of loss and comprehensive loss as common share options-based payments ($33,760 for the six months ended June 30, 2020). $28,611,554 represents the allocation of Company’s common share options-based payments to exploration activities, included within exploration expenses for the six months ended June 30, 2020 (June 30, 2020 – $200,355).

Activity and Valuation — Common Share Options

On July 1, 2020, 1,000,000 incentive stock options were granted to certain non employees. These incentive stock options, exercisable at $3.00 per share, expire on June 30, 2028. A total of 500,000 options vested on the date of the grant and the remaining options vest on July 1, 2021.

On July 7, 2020, 100,000 incentive stock options were granted to a consultant of the Company in return for the services provided by the consultant. These incentive stock options, exercisable at $Nil per share, expire on June 30, 2028 and vest immediately.

On December 23, 2020, 291,164 incentive stock options were granted to the consultants of the Company. Of these, a total of 270,000 incentive stock options are exercisable at $0.75 per share while 21,164 incentive stock options are exercisable at $0.25 per share. All options included in this grant vested immediately and expire on Dec 31, 2025.

The fair value of the options granted was estimated on the date of grant using the Black-Scholes option pricing model, with the following weighted average assumptions:

	2020		2019
Expected dividend yield	0.00	%	0.00	%
Expected stock price volatility	100.00	%	100.00	%
Risk-free interest rate	0.53	%	1.59	%
Expected life of options (years)	7.38		2.00
Estimated per share fair value of the Company’s Common Shares	3.60		1.75

Changes in these assumptions could have a material impact on the Company’s loss and comprehensive loss.

During the year ended December 31, 2020 the Company recognized $396,567 (2019 – $1,584,657) as part of financing costs within equity, for realizing the above-mentioned performance conditions. The Company also recognized additional $4,096,519 (2019 – $1,679,486) as common share option-based payments expense in the statement of loss and comprehensive loss. A total of $3,263,131 (2019 – $401,926) related to corporate matters and was charged to the statement of loss and comprehensive loss as common share options-based payments whereas $833,388 (2019 – $1,277,560), representing the allocation to exploration activities, was included within exploration expenses.

15. Income Taxes

Reconciliation of Effective Tax Rate

The Company is subject to Canadian federal and provincial tax for the estimated assessable profit for the years ended December 31, 2019 and 2020 at a rate of 27.00%. The Company had no assessable profit in Canada for all periods disclosed.

The tax expense at statutory rates for the Company can be reconciled to the reported loss for the year per the statement of loss and comprehensive loss as follows:

	For the year ended December 31 2020 $		For the year ended December 31 2019 $
Net loss for the year	(56,631,379	)	(43,072,371	)
Canadian Federal and Provincial income tax rates	27.00	%	27.00	%
Income tax recovery based on the above rates	(15,290,472	)	(11,629,540	)
Permanent differences	980,690		386,507
Effect of differences in future and foreign tax rates	11,151,898		10,042,909
Foreign exchange and other	(141,758	)	(275,813	)
Valuation allowance changes affecting the provision of income taxes	3,299,642		1,475,937
Total income taxes	—		—

The Company follows a comprehensive model for recognizing, measuring, presenting, and disclosing uncertain tax positions taken or expected to be taken on a tax return. Tax positions must initially be recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions must initially and subsequently be measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and relevant facts.

The Company currently has no uncertain tax positions and is therefore not reflecting any adjustments for such in its deferred tax asset.

The Company’s policy is to account for income tax related interest and penalties in income tax expense in the accompanying statements of operations. There have been no income tax related interest or penalties assessed or recorded.

The Company’s deferred income taxes are as follows:

	December 31 2020 $		December 31 2019 $
Deferred Tax Assets
Non-capital losses	10,925,043		5,156,568
Capital losses and other	70,162		68,777
Equipment	5,102		4,701
Share issuance costs	74,506		128,931
Total deferred income tax assets	11,074,813		5,358,977
Valuation allowance	(11,074,813	)	(5,358,977	)
Deferred tax asset recognized	—		—
Deferred tax liability recognized	(10,675,366	)	—

ASC 740 requires that the tax benefit of net operating losses, temporary differences and credit carry forwards be recorded as an asset to the extent that management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income within the carry forward period. Because of the Company’s history of operating losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly, has provided a valuation allowance.

The deferred tax liability is recognized due to the difference between the book value and the tax basis of the acquired assets, as part of the TOML Acquisition (Note 3).

Deductible temporary differences, unused tax losses and unused tax credits:

	December 31 2020 $	December 31 2019 $	Expiry Date Range
Non-capital losses	45,312,941	21,081,632	See below
Capital losses	519,720	509,463	Not applicable
Equipment	18,895	17,412	Not applicable
Share issuance costs	275,949	477,522	2021 to 2024

As at December 31, 2020, the Company had non-capital loss carry-forwards of $45,312,941 that may be used to offset future taxable income. These losses, if not utilized, will expire as follows:

	Canada	United States	Singapore	Tonga
2031	445,778	—	—	—
2032	478,464	—	—	—
2033	325,440	—	—	—

	20,703,827	2,780	10,214,470	14,391,864

As at December 31, 2019, the non-capital loss carry-forwards of $21,081,632 pertained to the following:

		Canada		United States		Singapore		Tonga
Loss carry-forwards		15,725,792		2,780		5,353,060		—

The Company files income tax returns in Canada, Singapore and the Kingdom of Tonga, and is subject to examination in these jurisdictions for all years since the Company’s inception in 2011. Fiscal years outside the normal statute of limitation remain open to audit by tax authorities due to tax attributes generated in those early years which have been carried forward and may be audited in subsequent years when utilized. The timing of the resolution, settlement and closure of any income tax audits is highly uncertain, and the Company is unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits. It is possible that the balance of gross unrecognized tax benefits could significantly change in the next 12 months. As at December 31, 2020, the 2020 tax year filings for the Company and its subsidiaries (where applicable) remain unfiled and have not been assessed by the relative tax Authorities.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Offering Costs Associated with the Initial Public Offering

Warrant Liabilities

The Company issued 15,000,000 warrants as part of the units offered in its Initial Public Offering and, simultaneously with the closing of Initial Public Offering, the Company issued in a private placement an aggregate of 9,500,000 private placement warrants. The Company accounts for the Warrants in accordance with the guidance contained in ASC 815-40-15-7D and 7F under which the Warrants do not meet the criteria for equity treatment and must be recorded as liabilities. Accordingly, the Company classifies the Warrants as liabilities at their fair value and adjusts the warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s statement of operations. The fair value of the Public Warrants was initially measured using a Modified Black Scholes Option Pricing Model and has subsequently been estimated using the Public Warrants’ quoted market price. The Private Placement Warrants are valued using a Modified Black Scholes Option Pricing Model.

Class A Ordinary Shares subject to possible redemption

Class A ordinary shares subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable Class A ordinary shares (including Class A ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, as of December 31, 2020, 22,726,721 Class A ordinary shares subject to possible redemption were presented at redemption value as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheet.

Income Taxes

FASB ASC Topic 740, “Income Taxes,” prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits as of December 31, 2020 and December 31, 2019. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of December 31, 2020 and December 31, 2019. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

i. TOML Acquisition

ii. Valuation of common share-based payments

• Expected Term — DeepGreen uses the term of the award when calculating the expected term due to insufficient historical exercise data.

• Expected Volatility — As DeepGreen’s shares are not actively traded, the volatility is based on a benchmark of comparable companies within the mining industry.

DeepGreen determines the fair value of common shares issued for services based on the most recent private placements.

- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.

Business combination, description			DeepGreen entered into an amended agreement with Allseas (the “Amendment # 3”) whereby, upon successful completion of the Business Combination, instead of issuing 10 million Common Shares to Allseas in connection with the PMTS, DeepGreen issued to Allseas a warrant to acquire 10 million DeepGreen Common Shares at a nominal value (the “Allseas Warrant”). The Allseas Warrant will vest and become exercisable upon successful completion of the PMTS and will expire on September 30, 2026. There are vesting conditions associated with the Allseas Warrant whereby a maximum of 10 million DeepGreen Common Shares would be issued if the PMTS is completed by September 30, 2023, gradually decreasing to 5 million DeepGreen Common Shares if PMTS is completed after September 30, 2025.

Business combination, description			The Allseas Warrant will be assumed by SOAC at the closing of the Business Combination to become a warrant to purchase The Metals Company (“TMC”) common shares, adjusted for the exchange ratio for the transaction. If the market price of the TMC common shares on June 1, 2022 is higher than $15 per share (as adjusted based on the exchange ratio for the closing of the Business Combination), the aggregate value of the shares underlying the warrant above $150 million as at June 1, 2022 will automatically become a commercial credit from Allseas to TMC equal to the excess value. This commercial credit will be effective on the vesting date of the Allseas Warrant and the Company will be able to exchange this excess value for any future goods and services from Allseas under the nodule collection and shipping contract for one year after commercial production.The cash payment of $30 million in the original agreement was also amended to be paid as follows, provided that the Business Combination is completed:• $10 million on June 30, 2021 with Allseas providing confirmation of placing an order of certain equipment and demonstrating certain progress on construction of the collector vehicle;• $10 million on the later of (i) January 1, 2022, and (ii) confirmation of successful collection of the North Sea test; and• $10 million upon successful completion of the PMTS.

Amendment agreement description			On March 4, 2021 and June 30, 2021, DeepGreen entered into an amended agreement with Allseas (the “Amendment #3 and “Amendment #4”, respectively”) whereby, upon successful completion of the Business Combination (Note 1), instead of issuing 10 million Common Shares to Allseas in connection with the PMTS, DeepGreen issued to Allseas, on March 4, 2021, a warrant to acquire 10 million DeepGreen Common Shares at a nominal value (the “Allseas Warrant”). The Allseas Warrant will vest and become exercisable upon successful completion of the PMTS and will expire on September 30, 2026. There are vesting conditions associated with the Allseas Warrant whereby a maximum of 10 million DeepGreen Common Shares would be issued if the PMTS is completed by September 30, 2023, gradually decreasing to 5 million DeepGreen Common Shares if PMTS is completed after September 30, 2025.
