Item 7.01 Regulation FD Disclosure.

As previously disclosed on

a Current Report on Form 8-K filed by Spring Valley Acquisition Corp. III, an exempted company limited by shares incorporated under the

Laws of the Cayman Islands (“SVAC”), with the U.S. Securities and Exchange Commission (the “SEC”)

on January 23, 2026, SVAC, entered into a Business Combination Agreement (as amended, the “Business Combination Agreement”)

with General Fusion Inc., a British Columbia limited company (the “Company” or “General Fusion”),

and 1573562 B.C. Ltd., a British Columbia limited company.

Attached hereto as Exhibit

99.1 and incorporated into this Item 7.01 by reference is an updated form of presentation (the “Updated Investor Presentation”)

to be used by the Company and SVAC in presentations for certain of the Company’s and SVAC’s shareholders and other persons.

The Updated Investor Presentation supersedes in all respects the earlier version of an investor presentation previously furnished as

Exhibit 99.1 of the Current Report on Form 8-K filed with the SEC on April 29, 2026.

The information in this Item

7.01, including Exhibit 99.1, is furnished and shall not be deemed to be “filed” for purposes of Section 18 of the Securities

Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise be subject to the liabilities of that section,

nor shall it be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities

Act”), or the Exchange Act, except as expressly set forth by specific reference in such filing.

Additional Information and Where to Find It

In connection with the transactions

contemplated by the Business Combination Agreement, the Company and SVAC filed their joint registration statement on Form F-4 (as amended,

the “Registration Statement”) with the SEC, which includes a preliminary prospectus with respect to SVAC’s securities

to be issued in connection with the Proposed Business Combination and a preliminary proxy statement in connection with SVAC’s solicitation

of proxies for the vote by SVAC’s shareholders with respect to the Proposed Business Combination and other matters to be described

in the Registration Statement. On June 12, 2026, the SEC declared the Registration Statement effective and SVAC filed the definitive

Proxy Statement (the “Proxy Statement”) with the SEC. On June 15, 2026, SVAC commenced mailing copies of the Proxy

Statement to SVAC’s shareholders as of the record date of June 12, 2026. This document does not contain all 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 SVAC has filed or may file with the SEC. Before making any investment or voting decision, investors and

security holders of SVAC and General Fusion 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 General Fusion, SVAC and the Proposed

Business Combination. Investors and security holders are 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 SVAC through the website maintained by the SEC at www.sec.gov.

In addition, the documents filed by SVAC may be obtained free of charge from SVAC’s website at https://sv-ac.com or by directing

a request to Spring Valley Acquisition Corp. III, Attn: Corporate Secretary, 4030 Maple Avenue, Suite 500, Dellas, TX 75219. The information

contained on, or that may be accessed through, the websites referenced in this document is not incorporated by reference into, and is

not a part of, this document.

Participants in the Solicitation

General Fusion, SVAC 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 SVAC’s shareholders in connection with the Proposed Business Combination.

For more information about the names, affiliations and interests of SVAC’s directors and executive officers, please refer to the

final prospectus from SVAC’s initial public offering, which was dated September 3, 2025 and filed with the SEC on September 4,

2025 (the “Final Prospectus”) and the Registration Statement, Proxy Statement and other relevant materials filed

or to be filed with the SEC in connection with the Proposed Business Combination when they become available. 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 SVAC’s shareholders generally, is included in the Registration Statement and the Proxy Statement. Shareholders, potential

investors and other interested persons should read the Registration Statement and the Proxy Statement carefully before making any voting

or investment decisions. You may obtain free copies of these documents from the sources indicated above.

No Offer or Solicitation

This document shall not constitute

a “solicitation” as defined in Section 14 of the Securities Exchange Act of 1934, as amended. This document shall not

constitute an offer to sell or exchange, the solicitation of an offer to buy or a recommendation to purchase, any securities, or a solicitation

of any vote, consent or approval, nor shall there be any sale, issuance or transfer of securities in any jurisdiction in which such offer,

solicitation or sale may be unlawful under the laws of such jurisdiction. No offering of securities in the Proposed Business Combination

shall be made except by means of a prospectus meeting the requirements of the Securities Act of 1933, as amended, or an exemption therefrom.

Cautionary Note Regarding Forward-Looking Statements

Certain statements included

in this document are not historical facts but are forward-looking statements. All statements other than statements of historical facts

contained in this document are forward-looking statements. Any statements that refer to projections, forecasts or other characterizations

of future events or circumstances, including any underlying assumptions, are also forward-looking statements. 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, SVAC’s, General Fusion’s,

or their respective management teams’ expectations concerning the Proposed Business Combination and expected benefits or timing

thereof; the outlook for General Fusion’s business, including its ability to commercialize MTF or any other fusion technology on

its expected timeline or at all; statements regarding the current and expected results of General Fusion’s LM26 program; the ability

to execute General Fusion’s strategies, including on any expected timeline or anticipated cost basis; projected and estimated financial

performance; anticipated industry trends; future capital expenditures; government regulation of fusion energy; and environmental risks;

as well as any information concerning possible or assumed future results of operations of General Fusion. The forward-looking statements

are based on the current expectations of the respective management teams of SVAC and General Fusion, as applicable, and are inherently

subject to uncertainties and changes in circumstance and their potential effects. 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 SVAC’s securities; (ii) the failure to satisfy the conditions

to the consummation of the Proposed Business Combination, including the adoption of the Business Combination Agreement by the shareholders

of SVAC and General Fusion and the receipt of regulatory approvals; (iii) market risks; (iv) the occurrence of any event, change

or other circumstance that could give rise to the termination of the Business Combination Agreement; (v) the effect of the announcement

or pendency of the Proposed Business Combination on General Fusion’s business relationships, performance, and business generally;

(vi) risks that the Proposed Business Combination disrupts current plans of General Fusion and potential difficulties in its employee

retention as a result of the Proposed Business Combination; (vii) the outcome of any legal proceedings that may be instituted against

General Fusion or SVAC related to the Business Combination Agreement or the Proposed Business Combination; (viii) failure to realize

the anticipated benefits of the Proposed Business Combination; (ix) the inability to maintain the listing of SVAC’s securities

or to meet listing requirements and maintain the listing of the combined company’s securities on Nasdaq; (x) the risk that

the Proposed Business Combination may not be completed by SVAC’s business combination deadline and the potential failure to obtain

an extension of the business combination deadline if sought by SVAC; (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, national

security tensions, and macro-economic and social environments affecting its business; (xii) laws and regulations governing General

Fusion’s research and development activities, and changes in such laws and regulations; (xiii) any failure to commercialize

MTF on the expected timeline or at all, including any failure to achieve the objectives of the LM26 program; (xiv) environmental

regulations and legislation; (xv) the effects of climate change, extreme weather events, water scarcity, and seismic events, and

the effectiveness of strategies to deal with these issues; (xvi) fluctuations in currency markets; (xvii) General Fusion’s

ability to complete and successfully integrate any future acquisitions; (xviii) increased competition in the fusion industry; (xix) limited

supply of materials and supply chain disruptions; and (xx) the risk that the proposed private placement of convertible preferred

shares and warrants by General Fusion (the “PIPE Financing”) may not be completed, or that other capital needed by the combined

company may not be raised on favorable terms, or at all, including as a result of the restrictions agreed to in connection with the PIPE

Financing. The foregoing list is not exhaustive, and there may be additional risks that neither SVAC nor General Fusion presently know

or that SVAC and General Fusion 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 Final Prospectus

and the risks described in the Registration Statement, or to be described in any amendment or supplement thereto; the risks described

in the definitive proxy statement/prospectus filed with the SEC on June 12, 2026, or to be described in any amendment or supplement thereto;

and those discussed and identified in filings made with the SEC by SVAC from time to time. General Fusion and SVAC 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 General Fusion nor SVAC 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 General Fusion or SVAC 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 SVAC’s public filings with the SEC, which are or will be (as applicable) accessible at www.sec.gov, and

which you are advised to review carefully.

BASICS OF PURSUING FUSION ON EARTH

To Make Fusion Happen on Earth

Without the gravity & pressure of the stars, systems must be built that can generate the necessary conditions here on Earth to force

fusion to happen and produce net fusion energy, known as the Lawson criterion (the right combination of temperature, density, and

energy confinement time)

Therefore, We Must Create a Machine That:

Converts to Power

Converts the captured fusion energy to

power for electricity & industrial heat use

Captures the Energy

Efficiently captures the energy released

from fusion

Creates Fusion

Under the right conditions, forces

plasma to fuse and release energy

Generates Plasma

A cloud of ionized hydrogen gas, often

made of Deuterium and Tritium

What is Fusion?

Fusion is the process by which two light atoms fuse to form a single heavier atom, releasing energy

ADDITIONAL DISCLAIMERS FOR CANADIAN PURCHASERS ONLY

Rights of Action for Damages or Rescission

Securities legislation in certain of the provinces of Canada may deem this Presentation to be an offering memorandum and accordingly provide purchasers with, in addition to any other rights they may have at law, statutory rights of rescission or damages, or

both, in the event this Presentation or any amendment hereto contains a misrepresentation. A “misrepresentation” is an untrue statement of a material fact or an omission to state a material fact that is required to be stated or that is necessary to make any

statement not misleading or false in the light of the circumstances in which it was made. These rights and remedies must be exercised within prescribed time limits and are subject to the defenses contained in the applicable securities legislation.

Purchasers should refer to the applicable provisions of the securities legislation of their province for the particulars of these rights or consult with a Canadian legal adviser. The following summary is subject to the express provisions of the applicable Canadian

securities laws, regulations and rules, and reference is made thereto for the complete text of such provisions. Such provisions may contain limitations and statutory defenses not described herein on which SVAC, General Fusion, NewCo and other applicable

parties may rely.

The following is a summary of the statutory rights of rescission or damages, or both, available to purchasers resident in certain of the provinces of Canada.

Ontario Purchasers

Ontario securities laws provide purchasers who have been delivered an offering memorandum in connection with a distribution of securities in reliance upon the “accredited investor” prospectus exemption in Section 73.3 of the Securities Act (Ontario) or National

Instrument – Prospectus Exemptions (“NI 45-106”) with a statutory right of action against the issuer of the securities for damages or rescission in the event that the offering memorandum or any amendment to it contains a misrepresentation, without regard to

whether the purchaser relied on the misrepresentation. If the purchaser elects to exercise its right of rescission, the purchaser will cease to have a right of action for damages. No such action shall be commenced more than: (a) in the case of an action for

rescission, 180 days after the date of the transaction that gave rise to the cause of action; or (b) in the case of an action for damages, the earlier of (i) 180 days after the purchaser first had knowledge of the facts giving rise to the cause of action or (ii) three years

after the date of the transaction that gave rise to the cause of action.

Ontario securities laws provide a number of limitations and defenses to such actions, including the following: (a) the issuer is not liable if it proves that the purchaser purchased the securities with knowledge of the misrepresentation; (b) in an action for damages,

the issuer shall not be liable for all or any portion of the damages that the issuer proves does not represent the depreciation in value of the securities as a result of the misrepresentation relied upon; and (c) in no case shall the amount recoverable exceed the

price at which the securities were offered.

These rights are not available for a purchaser purchasing in reliance upon the “accredited investor” prospectus exemption in NI 45-106 that is: (a) a “Canadian financial institution” or “Schedule III bank” (each as defined in applicable securities laws); (b) the

Business Development Bank of Canada; or (c) a subsidiary of any person referred to in paragraphs (a) or (b), if the person owns all of the voting securities of the subsidiary, except the voting securities required by law to be owned by the directors of the subsidiary.

Language of Documents

Upon receipt of this document, the purchaser hereby confirms that he, she or it has expressly requested that all documents evidencing or relating in any way to the offer and/or sale of securities (including for greater certainty any purchase confirmation or any

notice) be drawn up in the English language only. Par la réception de ce document, vous confirmez par les présentes que vous avez expressément exigé que tous les documents faisant foi ou se rapportant de quelque manière que ce soit à l’offre ou à la vente des

valeurs mobilières décrites aux présentes (incluant, pour plus de certitude, toute confirmation d’achat ou tout avis) soient rédigés en anglais seulement.
