US Elemental SPAC Merger: Lithium Upside Meets a Cash Clock
US Elemental is going public through a merger with Constellation Acquisition Corp I, with the combined company expected to list on Nasdaq under ULIT. The setup offers a large U.S. lithium resource story, but shareholders should watch valuation, redemptions, and dilution closely before the deal closes.

Company Overview
US Elemental is being formed to hold and develop Jindalee Lithium’s U.S. lithium asset, the McDermitt Lithium Project in Oregon and Nevada. The company’s pitch is straightforward: build a domestic source of battery-grade lithium carbonate in a market that remains heavily dependent on imports and a very small number of U.S. producers.
This is a development-stage mining company, not an operating producer. The materials emphasize exploration, feasibility work, permitting, financing, and eventual construction rather than current sales. The project completed a Pre-Feasibility Study in 2024 and is being marketed as a large-scale U.S. critical minerals asset with a potential magnesium by-product opportunity, FAST-41 transparency designation, and a DOE research agreement.
The industry backdrop is the company’s core bull case. Its deck says the U.S. produces less than 1% of global lithium supply and has only one active lithium mine site, while North American lithium chemical demand is forecast to grow at a 17% CAGR through 2040. Those are company-provided claims, but they explain why the deal is being framed as a strategic domestic supply-chain story.
The SPAC Deal
The transaction contemplates a $500 million target valuation and shows a $573.1 million pro forma enterprise value, with $588.1 million pro forma equity value and an assumption of $15 million net cash after transaction expenses. The deck says that EV excludes the impact of 10.33 million public warrants and assumes 100% redemptions in the illustrative table, which is important because this is a pre-revenue development story where the headline valuation is tied to future project economics rather than current cash flow.
On the SPAC side, the trust account held approximately $860,165, or $13.37 per public share, as of January 14, 2026. That trust balance is the pool that can shrink if public holders redeem, and the proxy makes clear that if the extension or business combination is not completed by the termination date, public shares are redeemed for the trust balance less taxes and up to $100,000 for dissolution expenses. The materials do not disclose an expected redemption percentage for the business combination vote itself, so shareholders should watch that closely.
Financing is still a key swing factor. The deal materials disclose a contemplated capital raise of $20 million to $30 million, including a $4.0 million commitment from an Antarctica Capital affiliate split between $1.5 million funded at signing and $2.5 million committed at closing. The April 9, 2026 8-K also says the minimum cash condition is $14.0 million, and the materials mention a $2.5 million commitment to purchase newly issued equity or equity-linked securities on substantially the same terms as PIPE financing agreements. The sponsor side also brings dilution: the presentation assumes 5.84 million founder shares retained by the sponsor and 10.33 million public warrants outstanding, and each CSTA warrant will be assumed by PubCo and converted into a warrant for one PubCo common share.
Constellation Acquisition Corp I currently trades under its SPAC ticker, which was not disclosed in the materials provided here, and the expected post-merger ticker is ULIT. The deal was announced April 9, 2026, and management said it expected to close in H2 2026. Based on that language, the first trading window looks like late Q3 to Q4 2026 if approvals and closing conditions are satisfied, but the transaction is still in the proxy/registration stage in the filings reviewed.

The SPAC route gives US Elemental a faster path to public markets than a traditional IPO and lets the company tell a forward-looking project story centered on resource size, expected production, and long-term economics. That matters here because the company is not yet a producer; the pitch depends on future permitting, financing, construction, and commissioning, which are easier to frame in a de-SPAC process than in a conventional IPO.
The merger also helps package the financing story around a public listing. The company is seeking transaction proceeds and additional capital to support the next phase of development, while the SPAC structure allows the sponsor and target to present project projections, including NPV, IRR, and EBITDA margin estimates, as part of the investor case. For a capital-intensive mining developer, that combination of public currency, sponsor backing, and access to PIPE-style funding is the main reason to choose this route.
Financial Highlights
US Elemental is pre-revenue in the materials reviewed, so there is no disclosed historical revenue base to analyze. Instead, the deal materials focus on project-level economics: a 63-year project life, 47,500 tonnes per annum of lithium carbonate for the first 10 years, a post-tax NPV of $3.23 billion, and a post-tax IRR of 17.9%. The deck also says the first 10 years could carry a 66% EBITDA margin, and the website repeats the 47,500 tpa figure and a greater-than-60% forecast EBITDA margin.
Those figures are projections, not historical results, and they are tied to a development asset that still needs permitting, financing, and construction. The transaction itself is also designed around a modest near-term cash target: $15 million net cash after transaction expenses, plus the contemplated $20 million to $30 million capital raise. That means the combined company will still need meaningful capital after closing, and the runway will depend on how much cash survives redemptions and how much additional financing is raised.
Risk Factors
The biggest de-SPAC risk is redemption pressure. The trust balance was only about $860,165, or $13.37 per share, as of January 14, 2026, and every redeemed share reduces cash available to the combined company. Because the minimum cash condition is $14.0 million, heavy redemptions could force the parties to lean harder on outside financing, renegotiate terms, or in the worst case jeopardize the deal.
Dilution is another major issue. The structure includes 5.84 million founder shares, 10.33 million public warrants, and additional PIPE-style or equity-linked securities. That creates a meaningful overhang before the company even starts building the mine. On top of that, this is still a development-stage mining project, so shareholders should watch permitting, feasibility, construction, and financing execution risk. The company also warns that future funding may be unavailable or highly dilutive, and closing still depends on SEC effectiveness, shareholder approvals, and Nasdaq listing approval.
Comparable Public Companies
The deck’s own comp set is narrow and useful: Ioneer (NASDAQ: IONR) and Lithium Americas (NYSE: LAC). Those are the closest public analogs disclosed in the materials because they are also large-scale lithium development names rather than producing miners. The presentation shows a rough EV comparison of $286 million for Ioneer, $573 million for US Elemental, and $1.95 billion for Lithium Americas.
On the multiple side, the deck cites EV per Mt LCE of 148.9x for Ioneer, 26.7x for US Elemental, and 43.8x for Lithium Americas, using the deck’s cited FactSet date. That puts US Elemental in the middle of the group on the sponsor’s framework, though these are deal-team-selected comps rather than an independent market screen. For cross-reference, the relevant tickers are IONR and LAC, and the SPAC side is Constellation Acquisition Corp I, which is expected to convert into ULIT after closing.

This is a classic de-SPAC setup where the story is bigger than the current financials. US Elemental has a large domestic lithium resource, a strategic U.S. supply-chain angle, and a headline valuation that reflects long-dated project economics rather than present-day earnings. That can work in a market that rewards critical-minerals exposure, but only if the company can get through the vote, preserve enough cash, and avoid excessive dilution.
Shareholders should watch three things as the deal moves toward closing: redemption levels, whether the minimum cash condition is still comfortably covered, and how much of the transaction value gets diluted by founder shares, warrants, and any additional financing. The reason this matters now is simple: the company is trying to turn a development-stage lithium asset into a public equity story before construction risk and capital needs become the dominant narrative. If the deal closes in the expected H2 2026 window, ULIT will be a name to track as a U.S. critical-minerals bet with a very real financing clock attached.
