Archimedes Tech SPAC Partners II Co. 8-K

What Happened

• On June 25, 2026, Archimedes Tech SPAC Partners II Co. (ATII) filed an 8-K noting that Forge Nano, Inc. issued a press release announcing a strategic partnership with Samsung SDI to enable U.S. production of advanced battery cells. The 8-K also references the Merger Agreement dated April 20, 2026 among ATII, its subsidiaries (Pubco and Merger Subs) and Forge Nano, and states that Pubco and Forge Nano have filed a Registration Statement on Form S-4 (including a proxy statement/prospectus) with the SEC related to the proposed business combination.

Key Details

• Press release date: June 25, 2026 — Forge Nano announced partnership with Samsung SDI to enable U.S. advanced battery cell production.
• Merger Agreement date: April 20, 2026 — agreement among ATII, Pubco, ATII Merger Sub entities and Forge Nano.
• Regulatory filing: Pubco and Forge Nano filed a Form S-4 registration statement (includes proxy/prospectus); materials will be mailed to shareholders after the SEC declares it effective.
• Solicitation/participants: ATII, Pubco, Forge Nano and their directors/officers may be “participants” in any proxy solicitation; investors are urged to read the Registration Statement and related documents.

Why It Matters

• The filings confirm progress toward combining Forge Nano with ATII (a SPAC transaction) and public disclosure of a commercial partnership with Samsung SDI that targets U.S. battery cell production—both developments are material to shareholders. Before voting on the proposed business combination, investors should review the Form S-4/proxy statement and the risk factors disclosed (e.g., approval conditions, redemption levels, construction or production delays, competition, raw material availability, IP and public-company readiness) because these may materially affect the outcome and future performance. This 8-K is informational and not an offer or solicitation; final decisions should be made based on the Registration Statement when it becomes available.
