Forge Nano Secures Additional $23 Million in PIPE Financing at $10.00 Per Share, Closes Series D with Samsung Investment Ahead of Public Listing

DENVER - July 14 - Forge Nano, Inc., a leading U.S.-based semiconductor equipment and advanced materials company pioneering Atomic Layer Deposition ("ALD") technology for artificial intelligence ("AI")-era chip manufacturing and defense battery applications, which has signed an agreement to merge with Archimedes Tech SPAC Partners II Co. ("Archimedes II") (NASDAQ: ATII), today announced an additional $23 million of committed PIPE financing ahead of its expected public listing on NASDAQ. All $23 million of the incremental PIPE financing was priced at $10.00 per share, increasing total PIPE commitments to $123 million.

The additional financing includes a $20 million strategic investment from Samsung SDI, comprised of $10 million in the Company's PIPE financing and $10 million in Forge Nano's Series D financing. Horizons Ventures has also participated in the Company's PIPE financing. Forge Nano has also successfully closed its Series D at $97 million, rounding out its pre-IPO capital formation.

Assuming no shareholder redemptions, Forge Nano's public listing would deliver over $367 million in pro forma cash comprised of the $123 million PIPE and $244 million in Archimedes II cash in trust. Upon closing of the business combination, Forge Nano expects that its substantial capital will accelerate commercialization of the Company's ALD semiconductor equipment platform and expand domestic manufacturing of advanced lithium-ion battery materials.

"These additional commitments represent a strong vote of confidence from both strategic and financial investors as we prepare to become a public company," said Paul Lichty, CEO of Forge Nano. "Samsung SDI's investment reinforces our shared vision for strengthening the domestic battery supply chain, while the new PIPE commitments at $10.00 per share demonstrate continued investor conviction in Forge Nano's long-term growth strategy. We believe we are exceptionally well positioned to scale manufacturing, execute on our commercial pipeline and meet growing demand across the semiconductor and defense battery markets."

The business combination with Archimedes II is expected to close in the second half of 2026, subject to approval by Archimedes II shareholders and the satisfaction of customary closing conditions.
