Archimedes Tech SPAC Partners II does not run a business; it runs a deadline. The blank-check company that went public on February 12, 2025, with 23,000,000 units and $231.15 million parked in a U.S. government treasury trust account filed its second-quarter report on August 13, 2026, reporting a net loss of $136.75 million for the three months ended June 30, 2026, and a balance sheet that now carries a $137.94 million derivative liability for the PIPE subscription commitment. That is the entire story in two numbers. The loss is not a loss at all; the GAAP hit reflects a $100 million one-time charge and a $37.94 million mark-to-market on a subscription agreement that exists to make a deal close. Strip those out and ATII earned $1.19 million in the quarter from interest on the trust account (operating loss of $977,614 plus $2.17 million in trust and bank-account interest income), on track to either consummate a merger or be forced to liquidate by November 12, 2026 - the company itself disclosed the going-concern doubt and the clock in the same filing.
The deal in question was signed April 20, 2026, with Forge Nano, Inc., a Thornton, Colorado–based atomic layer deposition (ALD) platform that develops conformal nanocoatings for lithium-ion battery cells and semiconductor devices. ATII will re-domicile to Delaware, Pubco will be renamed Forge Nano Holdings Inc., and the post-merger ticker is expected to be NANO (warrants NANOW). The enterprise value of the target is $1.2 billion, set against approximately $242 million in trust plus $123 million in committed PIPE financing ($100 million in the subscription agreement signed the same day as the merger announcement, plus $23 million announced July 14, 2026). The transaction is now in the live S-4 cycle, the latest amendment filed July 24, 2026; the proxy statement and EGM date are still to be set. The clock is the binding constraint: 21 months from the February 2025 IPO closes on November 12, 2026, 89 days after the quarterly report was filed.
The market is treating ATII like a trust account plus a warrant. At a reference price of $10.66 for the ordinary shares (close on August 13, 2026), the stock traded 4 cents above its trust-account-implied value of $10.62, while ATIIU units were $11.475 and ATIIW warrants $1.45. The deal has to clear three gates - registration effectiveness, the EGM shareholder vote, and the Nasdaq listing confirmation for the new ticker - and then the units separate and the ordinary shares become the new operating company. The thesis is binary. The numbers are the dates.
