Forge Nano Secures Additional $23 Million in PIPE Financing at $10.00 Per Share, Closes Series D with Samsung Investment Ahead of Public Listing
Forge Nano, Inc. said it secured an additional $23 million of committed PIPE financing at $10.00 per share, bringing total PIPE to $123 million, ahead of its expected NASDAQ listing via a merger with Archimedes Tech SPAC Partners II Co. (NASDAQ: ATII). Samsung SDI committed $20 million. Forge Nano also closed a $97 million Series D; pro forma cash would be over $367 million if no redemptions.
How this was made

The 30-second read
Why it matters
The incremental $23M PIPE at $10.00 per share, plus Samsung SDI’s $20M strategic investment, strengthens the financing package and may improve perceived deal certainty ahead of the shareholder vote and closing in 2H26.
Market read
A fresh, committed PIPE tranche and a named strategic investor are concrete deal-financing updates that can move pre-close sentiment for the SPAC and its merger target.
What to watch
Traders should monitor ATII shareholder vote outcomes, SEC filing progress, and any changes to closing conditions that could offset the benefit of incremental committed capital.
Background
Forge Nano is advancing toward a NASDAQ listing via a merger with SPAC Archimedes Tech SPAC Partners II (ATII) and has been building pre-IPO capital through PIPE and Series D financing.
Ticker impact
Forge Nano disclosed an additional $23M PIPE commitment and reiterated its merger with Archimedes II (NASDAQ: ATII) expected to close in 2H26.
Moderately positive bias for ATII into the 2H26 closing window, assuming no redemption shock or new regulatory/closing issues.
The article is a primary disclosure of incremental committed PIPE capital and a named strategic investor, which typically improves perceived certainty for SPAC business combinations.
Market effects
Supports funding momentum for ALD semiconductor equipment and advanced battery materials, potentially improving near-term sentiment for adjacent process equipment and materials suppliers.
Highlights domestic manufacturing expansion plans for advanced lithium-ion battery materials, which may resonate with US industrial policy narratives.
Samsung SDI’s participation signals continued global strategic interest in US-based semiconductor and battery supply chains.
Counterpoint
PIPE commitments can still be subject to deal mechanics and shareholder redemption dynamics; the pro forma cash assumes no redemptions.
