Company Overview
ATII Holdings is the newly formed public company in the merger structure; the operating target is Forge Nano, a materials science and advanced manufacturing company built around its Atomic Armor™ platform. The technology uses atomic-layer deposition and related coating processes to improve performance, durability, and safety across products, with management focusing on two main pillars: semiconductors and lithium-ion batteries.
Forge Nano says it was formed in 2011, spun out of the University of Colorado, and has grown to more than 120 employees and about 200 patents. It also says it has a Colorado facility for battery products and a clean room for semiconductor tool products. The company’s stated customer and partner base includes GM, Hanwha, LG, Volkswagen, OIC, Ascent Funds, and RockCreek, and it says it received a $100 million Department of Energy grant to build out a U.S. lithium-ion production facility.
The industry backdrop is a broad advanced-manufacturing and domestic supply-chain story, with management pointing to demand from AI/data infrastructure, defense and aerospace, electrification, and U.S. manufacturing/onshoring. The deck frames the addressable market at over $359 billion and positions Forge Nano as a platform company spanning both battery and semiconductor use cases rather than a single-application bet.
The SPAC Deal
Forge Nano is merging with Archimedes Tech SPAC Partners II Co., which currently trades on Nasdaq under the ticker ATII. The combined company is expected to trade on Nasdaq after closing, but the filings reviewed did not disclose a new post-merger ticker symbol. Based on the company’s Q3 2026 target and the July 2026 PIPE filing, the first trading window still looks like late Q3 2026.
The deal values Forge Nano at a $1.2 billion pre-money equity valuation and about $1.6 billion enterprise value at closing, with the investor presentation also citing a pro forma equity value of $1.59 billion. The SPAC trust is approximately $242 million, and the company expects about $317 million in net cash at closing, but both figures are subject to redemptions and final PIPE financing. The materials reviewed did not disclose a redemption percentage or an expected redemption assumption, which is the key variable retail investors should watch.
A PIPE was announced on July 14, 2026: Pubco, Forge Nano, and ATII entered subscription agreements for 2.3 million shares at $10.00 per share, for gross proceeds of about $23 million. The PIPE is expected to close concurrently with the business combination, subject to customary conditions. On dilution, the filing discloses a performance earnout of up to $900 million across three tiers, triggered at $15, $20, and $25 per share or $400 million, $600 million, and $800 million in trailing 12-month revenue, with a five-year term. That earnout is a major potential dilution source if the stock performs well.

The SPAC route gives Forge Nano a faster path to the public markets while letting management present forward projections in the deal materials. That matters here because the company is still scaling manufacturing capacity and commercial adoption across semiconductors and batteries, so the story is as much about future revenue ramp as current reported results.
The transaction also brings in sponsor backing and committed financing alongside the trust cash. In practical terms, the deal is designed to fund growth, support manufacturing scale-up, and help the company pursue its domestic supply-chain and advanced-manufacturing strategy without going through a traditional IPO process.
Financial Highlights
The clearest financial anchor in the materials is the expected cash at close: about $317 million, funded through the SPAC trust and the PIPE, though that amount can move with redemptions. The trust itself is approximately $242 million, and the PIPE adds about $23 million of gross proceeds if it closes as announced.
On operating performance, the presentation excerpt does not provide a full audited historical income statement, current revenue, gross margin, operating loss, or cash balance. What it does provide is a forward view: management projects about $76 million of revenue by 2027 in the base case. That is a projection, not historical revenue, and the deck says the deal is priced at 16.8x EV/2027 sales based on that forecast.
Risk Factors
The biggest de-SPAC-specific risk is redemption pressure. With roughly $242 million in trust and an expected $317 million in net cash at closing, the final cash outcome depends on how many shareholders redeem and whether the PIPE closes on schedule. If redemptions are heavy, the company’s cash runway and growth plans could be tighter than the headline numbers suggest.
Dilution is another major issue. The deal includes public warrants and a performance earnout of up to $900 million, both of which can weigh on per-share economics if the stock performs. Investors should also watch execution risk: Forge Nano is still scaling manufacturing and commercial adoption, and it is competing against large, well-capitalized peers in semiconductors and battery materials. The deal could also slip if the PIPE or closing conditions are not satisfied.
Comparable Public Companies
Forge Nano’s own peer set includes QuantumScape (QS), Amprius (AMPX), EOS, Innoviz (INVZ), Applied Materials (AMAT), Lam Research (LRCX), and ASML (ASML). The deck splits the comparison set between battery/materials growth names and mature semiconductor equipment names, which is a clue that the market is still deciding whether to value the company like an early-stage materials story or a scaled industrial platform.
The presentation says the mature advanced-manufacturing and semicap group trades around 5x to 13x forward sales, while Forge Nano is shown at 16.8x on its 2027 base case. It also says the battery growth peers were trading between $1.3 billion and $4.5 billion in equity value at the time of the presentation. That puts the deal at the richer end of the peer range on forward sales, which means execution will matter more than the headline market story.

This is a classic de-SPAC setup with a real industrial story underneath it: a materials platform tied to semiconductors, batteries, AI infrastructure, defense, and U.S. manufacturing. The bull case is that Forge Nano can turn its patents, customer relationships, and DOE-backed battery buildout into a meaningful revenue ramp; the bear case is that the current valuation already assumes a lot of that success, before the company has disclosed a full historical financial profile in the excerpts reviewed.
Shareholders should watch three things as the deal moves toward close: redemptions, PIPE completion, and whether the company can keep the expected cash-at-close profile intact. This matters now because the transaction is still pending, the expected close is Q3 2026, and the first public trading window appears to be late Q3 2026. If the cash stack holds and the market buys the growth story, the setup favors a differentiated industrial-tech listing; if not, dilution and redemption pressure could dominate the tape.
