US Elemental SPAC Merger: Lithium Scale Meets a Cash Clock
US Elemental is a newly formed U.S. lithium developer going public through a merger with Constellation Acquisition Corp I. The deal is aimed at a second-half-2026 close, but shareholders should watch the cash raise, redemption risk, and whether the project-stage valuation holds up.

Company Overview
US Elemental is a newly formed U.S. lithium development company that will hold Jindalee Lithium’s U.S. assets through HiTech Minerals, including the McDermitt Lithium Project in Oregon and the Clayton North Project in Nevada. The company is being positioned as a Nasdaq-listed domestic critical-minerals story focused on battery-grade lithium carbonate supply in the U.S.
The centerpiece is McDermitt, which the company describes as one of the largest lithium resources in the U.S. The April 2026 materials say the project has about 21.5 million tonnes of LCE, an expected 63-year project life, and a pre-feasibility study supporting roughly 47,500 tonnes per year of lithium carbonate in the first decade. The deck frames the opportunity as part of the broader U.S. push for energy security and domestic battery supply chains, with North American lithium chemical demand forecast to grow at a 17% CAGR through 2040.
The SPAC Deal
US Elemental is merging with Constellation Acquisition Corp I, a SPAC that currently trades under its own pre-merger ticker, which was not disclosed in the materials provided here. The combined company is expected to list on Nasdaq under ticker ULIT. The deal assigns US Elemental an implied pro forma enterprise value of about $571 million, while the April 9 announcement also referenced a $500 million equity value for Jindalee’s U.S. assets.
This is a de-SPAC, so the real question is how much cash survives the vote. Constellation’s trust was originally $310.0 million, but redemptions have already been heavy: $27.4 million was withdrawn in the January 27, 2025 redemption, and only $859,443 of redeemable Class A shares remained on the balance sheet as of December 31, 2025. The transaction still needs to clear the minimum cash condition of $14 million, and the June 4 425 said the deal contemplated a $20 million to $30 million capital raise. The only specifically disclosed committed financing was a $4.0 million commitment from affiliates of Antarctica Capital, with $1.5 million funded immediately and $2.5 million due at completion. The company said SEC review was underway and the transaction remained on track to close in the second half of 2026, so the estimated first-trading window is late Q3 to Q4 2026 if approvals land on schedule.
Dilution is another key overhang. Constellation’s 2025 10-K says the sponsor bought 5,466,667 private placement warrants at $1.50 each for $8.2 million, and the investor presentation says the valuation excludes 10.33 million public warrants and assumes 5.84 million founder shares retained by the sponsor. Those are the main dilution items retail investors should model before the ticker changes to ULIT.

The SPAC route gives US Elemental a faster path to public markets than a traditional IPO, and it lets the company market a long-dated project story with forward-looking projections already laid out in the investor deck. That matters for a development-stage lithium asset, where the pitch is based on resource scale, project economics, and future production rather than current revenue.
The deal also brings sponsor backing and a financing framework around the merger, even if the final cash stack is still being assembled. In a traditional IPO, a pre-production mining company would have a harder time packaging the asset, the projections, and the capital raise into one transaction. Here, the tradeoff is that shareholders have to absorb redemption risk, sponsor dilution, and the possibility that the final cash delivered at close is much smaller than the headline trust balance once was.
Financial Highlights
US Elemental is pre-revenue and development-stage, so there is no operating revenue to analyze yet. The company’s disclosed numbers are project projections: a $3.2 billion NPV at an 8% discount rate, a 17.9% post-tax IRR, roughly 47,500 tonnes per year of lithium carbonate in the first decade, and an expected 63-year project life. Those figures come from the McDermitt pre-feasibility study and should be treated as forward-looking assumptions, not current operating results.
On the SPAC side, Constellation reported a net loss of $3.14 million for 2025 and a $0.41 basic and diluted net loss per share for the non-redeemable shares. Cash runway for the combined company will depend on how much trust cash survives redemptions and whether the planned $20 million to $30 million raise closes in full. The disclosed materials do not provide a post-close operating cash runway because the company is not yet commercial.
Risk Factors
The biggest de-SPAC risk is cash leakage. Constellation’s trust has already been heavily depleted by redemptions, and the deal still needs to satisfy a $14 million minimum cash condition. If redemptions spike again or the financing package comes in light, the transaction could be delayed, restructured, or forced to close with less capital than the project needs.
The other major risk is execution. McDermitt is still a development-stage mining project, which means further feasibility work, permitting, financing, construction, and operational ramp-up all remain ahead. Investors also face dilution from sponsor promote mechanics, private placement warrants, and the 10.33 million public warrants referenced in the deck. On top of that, the deal still needs SEC effectiveness and Nasdaq listing approval, so the SEC review remains the critical path to close.
Comparable Public Companies
The company’s own deck points to Ioneer (NASDAQ: IONR) and Lithium Americas (NYSE: LAC) as the closest public comps. In the presentation’s peer slide, US Elemental is shown at roughly 26.7x EV per million tonnes of LCE, versus about 148.9x for Ioneer and 43.8x for Lithium Americas, with implied EVs of roughly $286 million, $573 million, and $1.95 billion, respectively.
That comp set tells you how the market tends to price lithium developers: resource scale and jurisdiction matter, but so does how far along the project is and how much capital still needs to be raised. The deck also emphasizes McDermitt’s domestic location and scale relative to peers, which is the core bull case. Other public names in the broader lithium space include Albemarle (NYSE: ALB) and SQM (NYSE: SQM), though they are operating producers rather than pure development-stage analogs.

This is a classic de-SPAC setup where the story is bigger than the current balance sheet. US Elemental has a large U.S. lithium resource, a clear domestic critical-minerals angle, and a Nasdaq ticker change to ULIT that could attract attention if the deal closes cleanly. But the market will care less about the headline resource and more about how much cash actually makes it through redemptions and whether the financing package is enough to keep the project moving.
Shareholders should watch three things: the final redemption level, whether the $20 million to $30 million raise is completed as planned, and whether SEC/Nasdaq approvals stay on track for a second-half-2026 close. That is why this matters now: the deal is not just a lithium story, it is a test of whether a pre-production mining asset can survive the SPAC process with enough capital and not too much dilution.
