Item 1.01. Entry into a Material Definitive Agreement

Amended and Restated Merger Agreement

As previously reported in its Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on August 5, 2025 (the “Prior Form 8-K”), on July 30, 2025, Spring Valley Acquisition Corp. II, an exempted company limited by shares incorporated under the Laws of the Cayman Islands (“SVII”), entered into an Agreement and Plan of Merger (the “Original Merger Agreement”) with Spring Valley Merger Sub II, Inc., a Nevada corporation (“Merger Sub 2”) and Eagle Energy Metals Corp., a Nevada corporation (“Eagle”). Pursuant to the Original Merger Agreement, among other things and pursuant to the terms and conditions set forth therein, on the day prior to the day of closing (the “Closing Date”), SVII was to domesticate as a corporation in the State of Nevada (“Redomicile”), and, in connection with the Redomicile, adopt the charter and bylaws, in each case, in the form to be mutually agreed between SVII and Eagle and (ii) Merger Sub 2 would merge with and into Eagle, (the “Merger”), with Eagle surviving the Merger as the Surviving Corporation (as defined in the Original Merger Agreement)”. As a result of the Merger, Eagle would have become a direct wholly owned subsidiary of SVII.

On September 29, 2025, SVII, Merger Sub 2, and Eagle restructured the transactions contemplated under the Original Merger Agreement by entering into an Amended and Restated Agreement and Plan of Merger (as the same may be amended, supplemented or otherwise modified from time to time, the “A&R Merger Agreement”) by and among Eagle Nuclear Energy Corp., a Nevada corporation (“New Eagle”), Spring Valley Merger Sub III, Inc., a Cayman Islands exempted company (“Merger Sub 1”), Merger Sub 2 (and together with Merger Sub 1, the “Merger Subs”), SVII, and Eagle. The A&R Merger Agreement amends and restates, in its entirety, the Original Merger Agreement. The restructured business combination transactions contemplated under the A&R Merger Agreement are referred to herein collectively as the “New Eagle Business Combination,” “Proposed Business Combination” or the “Transactions”.

The A&R Merger Agreement and the New Eagle Business Combination have been unanimously approved by the directors of SVII.

The following description of the New Eagle Business Combination does not purport to be complete and is qualified in its entirety by reference to the A&R Merger Agreement, a copy of which is included as Exhibit 2.1 to this Current Report on Form 8-K (this “Form 8-K”), and the other agreements filed herewith. SVII shareholders, warrant holders and other interested parties are urged to read such agreements in their entirety. Capitalized terms used below and not otherwise defined herein have the meanings assigned to them in the A&R Merger Agreement.

General Terms and Effects; Merger Consideration

Pursuant to the A&R Merger Agreement, each of the following transactions will occur in the following order: (a) (i) (A) immediately prior to the First Effective Time (as defined below), the sole outstanding Class B ordinary share, par value $0.0001 per share, of SVII (the “SVII Class B Ordinary Shares”) will convert into one Class A ordinary share, par value $0.0001 per share, of SVII (the “SVII Class A Ordinary Shares” and, together with the SVII Class B Ordinary Share, the “SVII Ordinary Shares”), (B) each outstanding SVII Unit (defined below) will separate and convert into its component securities, and (C) each outstanding SVII Right (defined below) will convert, in multiples of ten, into the underlying SVII Class A Ordinary Shares, and (ii) at the effective time (the “First Effective Time”), (A) Merger Sub 1 will merge (the “First Merger”) with and into SVII, with SVII surviving (the “Surviving Corporation”), and, as a result, SVII will become a direct, wholly owned subsidiary of New Eagle, (B) each ordinary share of Merger Sub 1 issued and outstanding immediately prior to the First Effective Time shall be converted into one share of SVII Class A Ordinary Share, (C) each SVII Class A Ordinary Share issued and outstanding immediately prior to the First Effective Time shall be canceled and converted into a number of shares of common stock, par value $0.0001 per share, of New Eagle (the “New Eagle Common Stock”), automatically on a one-for-one basis, following which all SVII Class A Ordinary Shares shall cease to be outstanding and shall automatically be canceled and retire and shall cease to exist, and (D) each then issued and outstanding warrant to purchase SVII Class A Ordinary Shares (the “SVII Warrants”) will convert automatically, on a one-for-one basis, into a warrant to purchase shares of New Eagle Common Stock (each, a “New Eagle Warrant”) and SVII shall assign all of its right, title and interests in the related Warrant Agreement (as defined herein) to New Eagle pursuant to an assumption agreement (the “Warrant Assumption Agreement”); (b) at the effective time (the “Second Effective Time”) of the Second Merger (as defined herein), (i) Merger Sub 2 will merge with and into Eagle (the “Second Merger”), with Eagle surviving as the surviving company (the “Surviving Company”), and, as a result, Eagle will become a direct, wholly owned subsidiary of New Eagle, (ii) each share of common stock of Merger Sub 2 issued and outstanding immediately prior to the Second Effective Time shall be converted into one share of common stock, par value $0.0001 per share, of Eagle (the “Eagle Common Stock”), (iii) each share of existing Eagle Common Stock issued and outstanding immediately prior to the Second Effective Time shall be canceled and converted into a number of shares of New Eagle Common Stock equal to the Exchange Ratio (as defined in the A&R Merger Agreement) resulting in an aggregate of 23,350,000 shares of New Eagle Common Stock being issued to the Eagle stockholders (the “Aggregate Merger Consideration”).

Transaction Consideration

Subject to, and in accordance with the terms and conditions of the A&R Merger Agreement, immediately prior to the First Effective Time, SVII shall cause each then issued and outstanding SVII Class B Ordinary Share to convert automatically, on a one-for-one basis, into one SVII Class A Ordinary Share following which all SVII Class B Ordinary Shares shall cease to be outstanding and shall automatically be canceled and retired and shall cease to exist.

Subject to, and in accordance with the terms and conditions of the A&R Merger Agreement, at the First Effective Time, by virtue of the First Merger and without any action on the part of SVII: (i) each then issued and outstanding SVII Class A Ordinary Share (including SVII Class A Ordinary Shares issued upon (a) the conversion of the SVII Class B Ordinary Shares pursuant to the A&R Merger Agreement, (b) the separation of the SVII units, consisting of one SVII Class A Ordinary Share, one SVII right (each, a “SVII Right”) and one-half (1/2) of one public SVII Warrant (each, a “SVII Public Warrant”) (collectively, the “SVII Units”) and (c) the conversion of the SVII Rights) will convert automatically, on a one-for-one basis, into one share of New Eagle Common Stock following which all SVII Class A Ordinary Shares shall cease to be outstanding and shall automatically be canceled and retired and shall cease to exist; and (ii) each then issued and outstanding SVII Warrant will convert automatically, on a one-for-one basis, into a New Eagle Warrant. Each Merger Sub 1 ordinary share, issued and outstanding immediately prior to the First Effective Time, shall be converted into one validly issued, fully paid and nonassessable SVII Class A Ordinary Share. Each share of Eagle Common Stock issued and outstanding immediately prior to the Second Effective Time shall be canceled and converted into a number of shares of New Eagle Common Stock equal to the Exchange Ratio, and each holder of a share of Eagle Common Stock issued and outstanding immediately prior to the Second Effective Time, shall receive for each share of Eagle Common Stock such number of shares of duly authorized, validly issued, fully paid and nonassessable New Eagle Common Stock (collectively, the Eagle Common Stock and New Eagle Common Stock so issued, the “Merger Consideration”) equal to the Exchange Ratio, rounded down to the nearest whole share. Each share of Merger Sub 2 common stock issued and outstanding immediately prior to the Second Effective Time shall be converted into one validly issued, fully paid and nonassessable share of Surviving Company common stock.

The Aggregate Merger Consideration is a number of shares of New Eagle Common Stock equal to the quotient obtained by dividing (i) $233,500,000 by (ii) $10.00.

Earnout

Following the Closing, if, at any time during the period following the Closing Date and expiring on the fifth (5^th) anniversary of the Closing Date (the “Earnout Period”), the VWAP of the shares of New Eagle Common Stock equals or exceeds $16.00 for any twenty (20) Trading Days within a period of thirty (30) consecutive Trading Days (the “Earnout Target”), then as soon as commercially practicable and in any event within five (5) Business Days following the achievement of the Earnout Target, New Eagle will issue 1,500,000 shares of New Eagle Common Stock (the “Earnout Shares”) to the persons set forth on the Earnout Payment Spreadsheet (the “Earnout Recipients”).

The issuance of the Earnout Shares will be provided for by resolution of the New Eagle Board. To the extent that the Earnout Recipients are service providers of New Eagle after the Closing, the issuance of the Earnout Shares will be made under the Eagle Nuclear Energy Corp. 2025 Equity Incentive Plan (the “New Eagle Equity Plan”). The New Eagle Equity Plan will reserve the Earnout Shares for issuance to the Earnout Recipients, which shall be issued only upon achievement of the Earnout Target.

If the Earnout Shares are issued to the Earnout Recipients within 180 days of the Closing Date, the Earnout Recipients shall not Transfer (as defined in the Lock-Up Agreement described below) any of the Earnout Shares until 180 days after the Closing Date. If the Earnout Target is not satisfied during the Earnout Period, the obligation to issue Earnout Shares pursuant to the A&R Merger Agreement will terminate and no longer apply.

Pursuant to the Amended and Restated PIPE Agreement, the PIPE Investor has agreed, among other things, to purchase, at the Closing, 29,700 shares of New Eagle’s Series A Cumulative Convertible Preferred Stock, par value $0.0001 per share, having the rights, preferences and privileges set forth in the Series A Preferred Stock Certificate of Designation (such stock the “Series A Preferred Stock”) and a warrant (the “Investor Warrants”) to purchase an aggregate of 2,500,000 shares of New Eagle Common Stock, at an exercise price of $12.00 per share, for an aggregate purchase price of $29,700,000 (the “Series A Preferred Stock Investment”). Each share of Series A Preferred Stock will have a stated value of $1,000.00 (the “Stated Value”).

The Amended and Restated PIPE Agreement includes customary representations and warranties from SVII, Eagle and the PIPE Investor and customary closing conditions. The Amended and Restated PIPE Agreement also includes customary covenants and agreements related to transfer restrictions, SEC reports, material non-public information and indemnification. The shares of New Eagle Common Stock underlying the shares of Series A Preferred Stock and the New Eagle Investor Warrants will be “Registrable Securities” under the Registration Rights Agreement.

Dividends: The shares of Series A Preferred Stock will accrue dividends daily at the rate of 12% per annum of the Stated Value (if paid in kind), plus the amount of previously accrued dividends paid in kind, or 10% per annum of the Stated Value (if paid in cash), plus the amount of previously accrued dividends paid in kind. Such dividends will compound semi-annually.

Liquidation Preference: Upon any liquidation or deemed liquidation event, the holders of shares of Series A Preferred Stock will be entitled to receive out of the available proceeds, before any distribution is made to holders of shares of New Eagle Common Stock or any other junior securities, an amount per share equal to the greater of (i) 100% of the Accrued Value (as defined in the Series A Preferred Stock Certificate of Designation) or (ii) such amount per share as would have been payable had all shares of Series A Preferred Stock been converted into shares of New Eagle Common Stock immediately prior to the liquidation event. Thereafter, the holders of shares of Series A Preferred Stock will be entitled to receive their pro-rata share, of the remaining available proceeds available for distribution to stockholders, on an as-converted to New Eagle Common Stock basis.

Voting: The shares of Series A Preferred Stock will vote together with the shares of New Eagle Common Stock as a single class, except (i) as required by law and (ii) as noted below under “— Protective Provisions.” Each holder of shares of Series A Preferred Stock shall be entitled to cast the number of votes equal to the number of whole shares of New Eagle Common Stock into which the shares of Series A Preferred Stock held by such holder are convertible as of the record date for determining stockholders entitled to vote on such matter.

Protective Provisions: For as long as 20% of the shares of Series A Preferred Stock issued as of the Closing are held by the PIPE Investor, New Eagle shall not, without the affirmative vote or action by written consent of holders of more than 80% of the issued and outstanding shares of Series A Preferred Stock (the “Requisite Holders”), take any of the following actions: (i) liquidate, dissolve or wind up the affairs of New Eagle; (ii) amend, alter, or repeal any provision of the New Eagle Certificate of Designation or any similar document of New Eagle in a manner adverse to the shares of Series A Preferred Stock; (iii) create or authorize the creation of or issue any other security convertible into or exercisable for any equity security unless such security ranks junior to the shares of Series A Preferred Stock with respect to its rights, preferences and privileges, or increase the authorized number of shares of Series A Preferred Stock; (iv) purchase or redeem or pay any cash dividend on any capital stock ranking junior to the Series A Preferred Stock, other than stock repurchased at cost from former employees and consultants in connection with the cessation of their service; (v) enter into any transaction with an affiliate that is not on arms’-length terms, other than the issuance of equity or awards to eligible participants under New Eagle’s incentive plan, equity plan or equity-based compensation plan, or with respect to employment, consulting or award agreements with respect to executive officers of New Eagle, in each case regardless of whether such person (or such person’s affiliates) would be considered an affiliate of New Eagle; or (vi) incur or guarantee any indebtedness, other than equipment leases or trade payables incurred in the ordinary course of business, if the aggregate indebtedness New Eagle and its subsidiaries for borrowed money following such action would exceed $5,000,000; provided, however, that the shares of Series A Preferred Stock shall not be considered indebtedness for purposes of this calculation.

Conversion: Each share of Series A Preferred Stock will be convertible into shares of New Eagle Common Stock at any time at the option of the holder at rate equal to the Accrued Value, divided by the then-applicable conversion price. The conversion price will initially be $11.88, subject to adjustments for stock dividends, splits, combinations and similar events and customary anti-dilution adjustments, including with respect to future issuances or sales of shares of New Eagle Common Stock at prices less than $10.00 per share. In addition, if the 20-day volume-weighted average price of the shares of New Eagle Common Stock on the twenty-first trading day following the date that is six months after the effective date of the resale registration statement to be filed pursuant to the Registration Rights Agreement is less than the conversion price then in effect, the conversion price will be adjusted to the greater of (i) such volume weighted average price and (ii) $7.50.

Put Rights: Unless prohibited by applicable law governing distributions to stockholders, the shares of Series A Preferred Stock shall be redeemable at the option of the Requisite Holders commencing any time after the fifth anniversary of the Closing at a price equal to the Accrued Value.

New Eagle Investor Warrants: At the closing of the Series A Preferred Stock Investment, the PIPE Investor will receive the New Eagle Investor Warrants. The New Eagle Investor Warrants will be immediately exercisable upon issuance at the Closing and will expire five years from the Closing Date. The New Eagle Investor Warrants include customary cash and cashless exercise provisions. Each New Eagle Investor Warrant will be initially exercisable at $12.00 per share of New Eagle Common Stock, subject to the same anti-dilution and other adjustments as the Series A Preferred Stock.

Warrant Assumption Agreement

In connection with the Closing, SVII, New Eagle and Continental Stock Transfer & Trust Company, as warrant agent, will enter into the Warrant Assumption Agreement. Such agreement will amend the warrant agreements governing the terms of the SVII Warrants (the “Warrant Agreements”), as SVII will assign all its rights, title, and interest in the Warrant Agreements to New Eagle. Pursuant to the Warrant Assumption Agreement, the SVII Warrants will no longer be exercisable for SVII Class A Ordinary Shares, and will be exchanged for New Eagle Warrants exercisable for shares of New Eagle Common Stock on substantially the same terms that were in effect prior to the Second Effective Time under the terms of the applicable Warrant Agreements.

A copy of the form of the Warrant Assignment Agreement is filed as Exhibit 10.6 to this Current Report on Form 8-K and is incorporated herein by reference, and the foregoing description of the Warrant Assignment Agreement is qualified in its entirety by reference thereto.

The securities to be offered and sold in connection with the Amended and Restated PIPE Agreement have not been registered under the Securities Act, in reliance upon the exemption from registration provided by Section 4(a)(2) of the Securities Act.

Additional Information and Where to Find It

In connection with the transactions contemplated by the A&R Merger Agreement, New Eagle intends to file with the SEC the Registration Statement, which will include a prospectus with respect to New Eagle’s securities to be issued in connection with the Proposed Business Combination and a proxy statement to be distributed to holders of SVII’s Class A Ordinary Shares in connection with SVII’s solicitation of proxies for the vote by SVII’s shareholders with respect to the Proposed Business Combination and other matters to be described in the Registration Statement (the “Proxy Statement”). After the SEC declares the Registration Statement effective, SVII plans to file the definitive Proxy Statement with the SEC and to mail copies to shareholders of SVII as of a record date to be established for voting on the Proposed Business Combination and other matters to be described in the Registration Statement. This document does not contain all of the information that should be considered concerning the Proposed Business Combination and is not a substitute for the Registration Statement, Proxy Statement or for any other document that SVII may file with the SEC. Before making any investment or voting decision, investors and security holders of SVII, New Eagle and Eagle are urged to read the Registration Statement and the Proxy Statement, and any amendments or supplements thereto, as well as all other relevant materials filed or that will be filed with the SEC in connection with the Proposed Business Combination as they become available because they will contain important information about New Eagle, Eagle, SVII and the Proposed Business Combination. Investors and security holders will be able to obtain free copies of the Registration Statement, the Proxy Statement and all other relevant documents filed or that will be filed with the SEC by SVII through the website maintained by the SEC at www.sec.gov.

II, Attn: Corporate Secretary, 2100 McKinney Avenue, Suite 1675, Dallas, Texas 75201.

Participants in the Solicitation

New Eagle, Eagle, SVII and their respective directors, executive officers and other members of management and employees may, under the rules of the SEC, be deemed to be participants in the solicitations of proxies from SVII’s shareholders in connection with the Proposed Business Combination.

Additional information regarding the participants in the proxy solicitation and a description of their direct and indirect interests, which may, in some cases, be different than those of SVII’s shareholders generally, will be included in the Registration Statement and the Proxy Statement, when they become available. Shareholders, potential investors and other interested persons should read the Registration Statement and the Proxy Statement carefully, when they become available, before making any voting or investment decisions.

In some cases, you can identify forward-looking statements by words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “expect,” “anticipate,” “believe,” “seek,” “strategy,” “future,” “opportunity,” “may,” “target,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” “preliminary,” or similar expressions that predict or indicate future events or trends or that are not statements of historical matters, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements include, without limitation, SVII’s, New Eagle’s, Eagle’s, or their respective management teams’ expectations concerning the Proposed Business Combination and expected benefits thereof; the outlook for Eagle’s or New Eagle’s business; the abilities to execute Eagle’s or New Eagle’s strategies; projected and estimated financial performance; anticipated industry trends; the future price of minerals; future capital expenditures; success of exploration activities; mining or processing issues; government regulation of mining operations; and environmental risks; as well as any information concerning possible or assumed future results of operations of Eagle or New Eagle.

There can be no assurance that future developments will be those that have been anticipated. These forward-looking statements involve a number of risks, uncertainties or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, (i) the risk that the Proposed Business Combination may not be completed in a timely manner or at all, which may adversely affect the price of SVII’s securities; (ii) the risk that the Proposed Business Combination may not be completed by SVII’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by SVII; (iii) the failure to satisfy the conditions to the consummation of the Proposed Business Combination, including the approval of the A&R Merger Agreement by the shareholders of SVII and the receipt of regulatory approvals; (iv) market risks; (v) the occurrence of any event, change or other circumstance that could give rise to the termination of the A&R Merger Agreement; (vi) the effect of the announcement or pendency of the Proposed Business Combination on Eagle’s business relationships, performance, and business generally; (vii) risks that the Proposed Business Combination disrupts current plans of Eagle and potential difficulties in its employee retention as a result of the Proposed Business Combination; (viii) the outcome of any legal proceedings that may be instituted against Eagle or SVII related to the A&R Merger Agreement or the Proposed Business Combination; (ix) failure to realize the anticipated benefits of the Proposed Business Combination; (x) the inability to maintain the listing of SVII’s securities or to meet listing requirements and maintain the listing of the combined company’s securities on Nasdaq Capital Market or a comparable exchange; (xi) the risk that the price of the combined company’s securities may be volatile due to a variety of factors, including changes in laws, regulations, technologies, natural disasters or health epidemics/pandemics, national security tensions, and macro-economic and social environments affecting its business; (xii) fluctuations in spot and forward markets for lithium and uranium and certain other commodities (such as natural gas, fuel oil and electricity); (xiii) restrictions on mining in the jurisdictions in which Eagle operates; (xiv) laws and regulations governing Eagle’s operation, exploration and development activities, and changes in such laws and regulations; (xv) Eagle’s ability to obtain or renew the licenses and permits necessary for the operation and expansion of its existing operations and for the development, construction and commencement of new operations; (xvi) risks and hazards associated with the business of mineral exploration, development and mining (including environmental hazards, potential unintended releases of contaminants, industrial accidents, unusual or unexpected geological or structural formations, pressures, cave-ins and flooding); (xvii) inherent risks associated with tailings facilities and heap leach operations, including failure or leakages; the speculative nature of mineral exploration and development; the inability to determine, with certainty, production and cost estimates; inadequate or unreliable infrastructure (such as roads, bridges, power sources and water supplies); (xviii) environmental regulations and legislation; (xix) the effects of climate change, extreme weather events, water scarcity, and seismic events, and the effectiveness of strategies to deal with these issues; (xx) risks relating to Eagle’s exploration operations; (xxi) fluctuations in currency markets; (xxii) the volatility of the metals markets, and its potential to impact Eagle’s ability to meet its financial obligations; (xxiii) disputes as to the validity of mining or exploration titles or claims or rights, which constitute most of Eagle’s property holdings; (xxiv) Eagle’s ability to complete and successfully integrate acquisitions; (xxv) increased competition in the mining industry for properties and equipment; (xxvi) limited supply of materials and supply chain disruptions; (xxvii) relations with and claims by indigenous populations; (xxviii) relations with and claims by local communities and non-governmental organizations; and (xxix) the risk that the Series A Preferred Stock Investment may not be completed, or that other capital needed by the combined company may not be raised on favorable terms, or at all. The foregoing list is not exhaustive, and there may be additional risks that neither SVII, Eagle, nor New Eagle presently know or that SVII, Eagle, and New Eagle currently believe are immaterial. You should carefully consider the foregoing factors, any other factors discussed in this document and the other risks and uncertainties described in the “Risk Factors” section of the 2024 Form 10-K, the risks to be described in the Registration Statement, which will include the preliminary Proxy Statement/prospectus, and those discussed and identified in filings made with the SEC by SVII from time to time. Eagle, New Eagle, and SVII caution you against placing undue reliance on forward-looking statements, which reflect current beliefs and are based on information currently available as of the date a forward-looking statement is made. Forward-looking statements set forth in this document speak only as of the date of this document. Neither Eagle, SVII, nor New Eagle undertakes any obligation to revise forward-looking statements to reflect future events, changes in circumstances, or changes in beliefs. In the event that any forward-looking statement is updated, no inference should be made that New Eagle, Eagle or SVII will make additional updates with respect to that statement, related matters, or any other forward-looking statements. Any corrections or revisions and other important assumptions and factors that could cause actual results to differ materially from forward-looking statements, including discussions of significant risk factors, may appear, up to the consummation of the Proposed Business Combination, in SVII’s public filings with the SEC, which are or will be (as appropriate) accessible at www.sec.gov, and which you are advised to review carefully.
