**On June 10, 2026, the following article was published online by PR Newswire (www.prnewswire.com):**

**The Company Trying to Make Clean Power Cheap Enough to Win**

*Issued on behalf of General Fusion Inc.*

Companies mentioned: General Fusion Inc. (proposedNasdaq: GFUZ via Spring Valley Acquisition Corp. III (NASDAQ: SVAC)), Oklo Inc. (NYSE: OKLO), NuScale Power Corporation (NYSE: SMR), Nano Nuclear Energy Inc. (NASDAQ: NNE), Spring Valley Acquisition Corp. III (NASDAQ: SVAC)

**KEY TAKEAWAYS**

**A major third-party recognition just arrived.** General Fusion was ranked first on TIME's list of the World's Top GreenTech Companies of 2026, a recognition that puts the fusion-energy developer at the center of one of the most closely watched races in clean power.

**This is not just a science story anymore.** General Fusion says its world-first Lawson Machine 26, or LM26, is already in operation and is designed to pursue key technical milestones on the road to practical magnetized target fusion at a commercially relevant scale.

**The public-markets angle matters.** General Fusion is advancing towards its previously announced proposed business combination with Spring Valley Acquisition Corp. III, a transaction the company says would position it to become the first publicly traded pure-play fusion company.

**The broader power-and-decarbonization trade is active.** Exchange-listed names tied to next-generation nuclear and clean-power infrastructure, including Oklo, Inc., NuScale, Nano Nuclear Energy, and Spring Valley Acquisition Corp III continue to keep investor attention on the race to secure scalable, low-carbon electricity.

**Retail investors now have a much easier story to follow.** Between the TIME recognition, the LM26 machine, and the proposed path to the public markets, General Fusion has moved beyond abstract "fusion someday" language and into a narrative built around milestones, hardware, and execution.

VANCOUVER, BC, June 10, 2026 /PRNewswire/ -- Equity Insider News Commentary — Clean energy stories often sound impressive right up until investors ask the obvious question: can this actually scale, and can it ever make economic sense? General Fusion is betting that fusion does not need to stay in the realm of science-fiction headlines forever. The Vancouver-based company just landed the top spot on TIME's list of the World's Top GreenTech Companies of 2026 at a moment when it is also advancing toward the public markets through its proposed business combination with Spring Valley Acquisition Corp. III (NASDAQ: SVAC).

That combination of third-party recognition, visible hardware progress, and a live capital-markets path is part of what makes this story stand out. Rather than asking investors to simply believe in the distant promise of fusion, General Fusion is trying to show that its approach has moved into a more concrete phase, with a real machine, a defined technical roadmap, and a transaction that could make it one of the first pure-play fusion names available to public-market investors.

**Why TIME's Ranking Matters**

General Fusion was selected from more than 8,300 applicants worldwide for TIME's 2026 GreenTech ranking, which was produced with Statista. The company said the recognition reflects both the innovation behind its fusion technology and the execution it has shown as it pushes toward commercialization.

That matters because fusion remains one of the hardest areas in energy for investors to handicap. The opportunity is enormous if anyone can deliver reliable, zero-carbon baseload electricity at scale, but the sector has also spent decades burdened by long timelines and skepticism. A high-profile ranking from TIME does not solve the engineering challenge, but it does provide a credible outside signal that General Fusion is being taken seriously as one of the leading companies in the field.

**The Big Idea Behind General Fusion**

General Fusion is pursuing Magnetized Target Fusion, or MTF, which the company presents as a more practical route to commercial fusion power. According to the company, the approach is designed to avoid the need for superconducting magnets and high-powered lasers while allowing the use of existing materials to build durable machines that could ultimately produce cost-effective energy.

That practical-engineering angle is central to the investment story. Fusion has always captured attention because of its potential to deliver clean, abundant energy, but General Fusion's pitch is that the winner in this market may not be the company with the most elegant physics on paper. It may be the one that can build something durable, repeatable, and economically viable enough to plug into the real-world power system.

More information on the company's technology, commercialization approach, and long-term energy thesis can be found on the General Fusion homepage.

**LM26: The Machine Investors Can Actually Point To**

One of the most important parts of the latest General Fusion story is that there is a visible machine at the center of it. The company says it designed, built, and began operating Lawson Machine 26, or LM26, in under two years, describing it as the world's first Magnetized Target Fusion demonstration machine built at a commercially relevant scale.

According to the company, LM26 mechanically compresses plasma with a lithium liner at 50% commercial-scale diameter. It is intended to pursue several major technical milestones, beginning with plasma heating to 1 keV, then 10 keV, and ultimately the Lawson criterion, which refers to the combination of fusion parameters needed to produce net fusion energy in the plasma.

For retail investors, this is where the story gets easier to track. Instead of watching only concept slides and future aspirations, the market now has an operating demonstration machine and a sequence of milestones to follow. That does not remove the technical risk, but it gives the story a much more tangible shape.

**The Race to Go Public**

General Fusion announced in January 2026 that it plans to go public through a proposed business combination with Spring Valley Acquisition Corp. III. Reuters reported that the transaction was valued at roughly $1 billion, and the company said it expects to list on Nasdaq under the ticker GFUZ if the deal closes.

The company has framed the transaction as a way to secure the capital needed to continue operating LM26 and pursue the milestones required to move toward a first-of-a-kind plant. According to both company materials and outside reporting, the deal would make General Fusion one of the first publicly traded pure-play fusion companies, a milestone that could bring a new class of retail investors into a sector that has largely remained private.

Of course, the SPAC path comes with the usual caveats. General Fusion's own materials include extensive forward-looking statement disclosures, and the proposed business combination remains subject to regulatory review, shareholder approval, market conditions, and other customary risks described in the SEC materials.

**The Broader Energy Tape**

General Fusion is not building in a vacuum. Investor interest in advanced nuclear, fusion, and next-generation clean-power infrastructure has remained elevated as electricity demand climbs and energy security has moved back to the center of policy and capital-markets conversations.

**Oklo Inc. (NYSE: OKLO)** remains one of the most visible publicly traded advanced-nuclear names in the market. Recent investor commentary has focused on the company's licensing work with the U.S. Nuclear Regulatory Commission and its ambition to bring a commercial unit online later this decade, helping keep the stock in the middle of the new-nuclear conversation.

**NuScale Power Corporation (NYSE: SMR)** continues to serve as one of the better-known public proxies for investor interest in next-generation nuclear infrastructure. Spring Valley Acquisition Corp.'s earlier business combination with NuScale is also part of the reason General Fusion's proposed business combination with Spring Valley Acquisition Corp. III carries added credibility in the clean-energy SPAC lane.

**Nano Nuclear Energy Inc. (NASDAQ: NNE)** has become another closely watched name in the emerging advanced-reactor trade. As investors search for scalable, low-carbon baseload power solutions, companies promising smaller, more flexible reactor architectures have stayed on the radar alongside fusion developers.

**Spring Valley Acquisition Corp. III (NASDAQ: SVAC)** is not a power producer, but it is central to this story because it is the listed vehicle General Fusion plans to merge with. Spring Valley Acquisition Corp. III describes itself as focused on power infrastructure and decarbonization, and its management's track record in prior energy-related combinations is part of what has kept attention on the proposed deal.

**Why This Story Can Travel**

The reason this article has pickup potential is that the General Fusion story taps into several narratives at once. It is a clean-energy story, a climate story, a power-demand story, a commercialization story, and a public-markets story all rolled into one.

At the same time, the company is careful to frame fusion as an engineering and execution challenge, not a guaranteed breakthrough. CEO Greg Twinney said the company's TIME recognition reflects both its technology and its execution, while also emphasizing that practical fusion power will depend on disciplined investment and a clear path to commercialization.

That balance matters. It keeps the article from sounding like a moonshot fantasy while preserving the part that makes fusion compelling in the first place: if a company can build reliable, cost-effective fusion power, the implications for electricity markets, decarbonization, and energy security would be enormous.

**Why Retail Investors May Care**

Retail investors have spent years hearing that fusion is always a decade away. What makes General Fusion's latest update more interesting is that it gives the market a cleaner framework for following the story: outside validation from TIME, a named machine already in operation, specific technical milestones, and a defined route to the public markets through Spring Valley Acquisition Corp. III.

That does not make the company low-risk. Fusion remains an extraordinarily difficult technical and commercial challenge, and General Fusion's own cautionary language makes that clear. But for investors willing to follow long-duration technology stories, this is one of the more concrete and visible fusion narratives currently developing.

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, which includes a preliminary proxy statement/prospectus, 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.
