Company Overview
ATII Holdings is the target in this de-SPAC, but the operating business described in the SEC materials is Forge Nano, a U.S.-based semiconductor equipment and advanced materials company built around Atomic Layer Deposition (ALD). Its core platform, Atomic Armor®, is a nano-scale coating system the company says is designed to improve performance for AI-era chip manufacturing and defense battery applications. The company also says it plans to expand into pharmaceuticals, data centers, and quantum computing.
The business is still in an early commercial stage. The SEC materials include a going-concern explanatory paragraph from the auditor, which is a strong sign the company is still dependent on outside capital to fund growth. The company is headquartered in the Denver/Thornton, Colorado area based on the SEC filing address and related materials. Industry-wise, Forge Nano is positioning itself at the intersection of semiconductor equipment and advanced battery materials, two markets tied to AI infrastructure, domestic supply-chain reshoring, and defense spending.
The SPAC Deal
The transaction values Forge Nano at $1.2 billion pre-money equity value. The company’s announcement says that, assuming no redemptions, the deal implies about $1.595 billion in total equity value, and later 425 materials describe an enterprise value of about $1.6 billion, subject to redemptions and final PIPE financing. That is a rich valuation for a company that is still early enough to carry a going-concern note, so shareholders should watch whether the market treats this as a platform story or a pre-profitability stretch valuation.
ATII said it had about $242 million in trust as of April 9, 2026, later updated to approximately $244 million. The original deal included a $100 million PIPE, and the July 14 update raised total PIPE commitments to $123 million after $23 million of incremental commitments, including a $20 million strategic investment from Samsung SDI split between $10 million in the PIPE and $10 million in Forge Nano’s Series D financing. The July 14 filing says the minimum cash condition has been satisfied with committed capital, but final cash at closing still depends on redemptions. The capital stack also carries meaningful dilution: sponsor/founder shares, public warrants, PIPE warrants for 15,000,000 shares at a $10.00 exercise price, and an earnout of up to $900 million in shares tied to trading-price and revenue milestones. ATII currently trades as ATII, and the combined company is expected to trade as NANO, with warrants as NANOW. The deal was announced April 21, 2026, the S-4 was filed May 5, 2026, and the company expects to close in the second half of 2026, so the first trading window is still likely late Q3 to Q4 2026 if approvals and redemptions cooperate.

The SPAC route gives Forge Nano faster access to capital than a traditional IPO and lets it present a forward-looking growth story around AI chips, defense batteries, and future expansion markets. The deal also brings in strategic validation from Samsung SDI and other PIPE investors, which can matter for customer credibility in a capital-intensive hardware business.
The use of proceeds is straightforward: fund commercialization of the ALD semiconductor platform and expand domestic battery materials manufacturing. A de-SPAC also allows the company to market projections in the S-4/proxy materials, which is often a key reason early-stage companies choose this route over a standard IPO. That said, projections are only as good as execution, and the company’s early-stage profile means the market will focus heavily on whether the capital raised is enough to bridge the business to scale.
Financial Highlights
The most important financial takeaway from the materials provided is not a revenue figure but the stage of the business: the auditor’s going-concern paragraph signals ongoing funding needs and limited margin for error. The company’s own investor materials frame it as a growth platform rather than a mature cash generator, and the SEC excerpts reviewed do not surface a full historical revenue table.
On the balance sheet side, the pro forma cash picture is the key near-term metric. The July 14 425 says Forge Nano would have more than $367 million in pro forma cash assuming no redemptions, combining roughly $244 million of trust cash with $123 million of PIPE commitments. That is a meaningful war chest for commercialization, but it is still contingent on redemption outcomes, and the company’s forward projections should be treated as projections, not guarantees.
Risk Factors
The biggest de-SPAC-specific risk is redemption pressure. ATII’s trust is about $242 million to $244 million, but that cash can leave if public stockholders redeem, and the final closing economics depend on how much stays in the deal. Even with the minimum cash condition satisfied, a heavy redemption wave could reduce the cash available to Forge Nano and weaken the post-close setup.
Dilution is another major overhang. Retail investors should watch the sponsor promote, public warrants, PIPE warrants on 15,000,000 shares at a $10.00 strike, and the large earnout tied to trading and revenue milestones. Beyond deal mechanics, the company faces execution risk, competition, raw material availability and cost, delays in production facility construction or operation, IP and data protection risk, public-company readiness risk, and the possibility that the merger could slip if shareholder approval, SEC effectiveness, or Nasdaq listing approval is delayed. The going-concern note makes the cash runway question especially important.
Comparable Public Companies
Forge Nano’s own materials point to QuantumScape (QS), EOS, Innovex, and Amprius (AMPX) as peer names, which places the company in a high-growth, pre-profitability advanced materials and battery-tech bucket. Those peers were described in the deck as trading in roughly a $1.3 billion to $4.5 billion equity-value band at the time of the presentation.
For the battery-materials angle, Enovix (ENVX) is also a reasonable public comp, though it was not explicitly named in the quoted materials. The broader comp set suggests the market is comparing Forge Nano to companies that are still scaling, still investing heavily, and still being valued more on future adoption than current earnings power. That makes the setup sensitive to sentiment around growth, capital intensity, and dilution.

This is a classic de-SPAC where the story is bigger than the current financials. The bull case is a strategically relevant platform in AI semiconductor manufacturing and defense batteries, backed by Samsung SDI and a sizable cash raise. The bear case is equally clear: an early-stage company priced at about $1.6 billion EV, with redemption risk, multiple layers of dilution, and a going-concern warning.
Shareholders should watch the final redemption level, the amount of cash that actually makes it through closing, and whether the market is willing to underwrite the NANO ticker as a long-duration growth story. Why this matters now: the deal is still pending, the expected close is in the second half of 2026, and the next move will likely be driven by vote timing, SEC effectiveness, and whether the PIPE plus trust cash are enough to support the commercialization plan without overwhelming dilution.
