$585 million. That is the implied enterprise value of Nth Cycle's merger with Kensington Capital Acquisition Corp. VI, the deal that takes one of the few American critical-mineral refiners onto the New York Stock Exchange. That is the bet.
Nth Cycle, founded in 2017 and based in Burlington, Massachusetts, converts scrap metal, battery waste and mined ore into industrial-grade nickel, cobalt, copper and rare earth material. Its OYSTER system runs on electricity instead of the high-heat furnaces and heavy chemical baths of a traditional refinery, and it fits inside an existing building. The company says it operates the first US refinery producing high-purity nickel-cobalt mixed hydroxide product from recycled battery feedstock. It positions itself midstream: the processing layer between mine and manufacturer, where the value is created offshore today.
Kensington is a special purpose acquisition company (SPAC) that raised $200 million in its own IPO in March 2026. It is the sixth vehicle in a sponsor family built around automotive and industrial deals, chaired by Justin Mirro with former Daimler chief Dieter Zetsche as vice chairman. The combined company will be named Nth Cycle Holdings Inc. and trade under the ticker NTH, with closing targeted for the fourth quarter of 2026.
The chokepoint the deal is priced around
Refining is where Western mineral supply chains fail. China controls roughly 85% of the world's mineral refining, including material mined in the United States and its allies. A presidential determination issued this summer reclassified battery scrap and electronic waste as strategic feedstocks, giving federal officials the authority to restrict their export.
The deal's numbers track that chokepoint. The $585 million enterprise value assumes no redemptions. It wraps in up to $230 million from Kensington's trust, plus a private investment in public equity (PIPE) of up to $100 million. Of that, $40 million is already committed. Nth Cycle also holds a 10-year offtake term sheet with commodities trader Trafigura valued at roughly $1.1 billion.
Nth Cycle's co-founder and chief executive, Megan O'Connor, puts it plainly: critical minerals across the West carry little commercial value until refined. Her company's module slots into an existing recycler's or miner's site, which compresses years of permitting and billions of dollars of capex out of the build-out.
One deal in a wave
Nth Cycle is not alone. Controlled Thermal Resources agreed to a $4.7 billion merger with Plum Acquisition Corp. IV to fund its Salton Sea lithium project. Solid-state battery maker ProLogium struck a $3.8 billion SPAC deal tied to a French gigafactory. HiTech Minerals merged at a $571 million valuation, Key Mining at $230 million.
The refining step is the leverage point.
Three markets anchor the thesis: rare earths for military and electronics, copper for power and data transmission, battery materials for energy storage and transportation. All three run through a refining layer with almost no domestic capacity.
Where the risk sits
SPAC deals carry structural risk. Kensington shareholders can redeem their shares at $10 before closing, which shrinks the cash actually delivered. The $60 million gap between committed and target PIPE still needs to close. The S-4 registration statement, submitted confidentially to the U.S. Securities and Exchange Commission (SEC) on August 7, must clear review and win stockholder votes at both companies.
Nth Cycle's defense is concrete. It already runs the first US refinery converting recycled battery feedstock into mixed hydroxide product. Trafigura has signed a 10-year offtake commitment worth about $1.1 billion. The open questions are scale and how much headline capital survives the closing process.
The valuation is secondary
As we wrote in August, biology is entering the battery-metal race through Mint's Linca spinout. Nth Cycle attacks the same bottleneck with electrochemistry and public money. Same target, different mechanism.
For investors, the deal turns on execution: whether domestic refining can scale before the next commodity downturn. Watch the cash actually received at close, the PIPE build-out, and refinery commissioning timelines. If refining capacity comes online, the first public vehicle for it becomes the sector's reference point. If not, the ticker NTH will be a reminder that the bottleneck was never capital.
