ATII and Forge Nano caution you that these forward-looking statements are subject to numerous risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of either ATII or Forge Nano. Risks and uncertainties include, among other things: (i) risks related to the occurrence of any event, change or other circumstances that could delay the business combination or give rise to the termination of the agreements related thereto; (ii) risks related to the outcome of any legal proceedings that may be instituted against ATII or Forge Nano following announcement of the transactions; (iii) risks related to the inability to complete the proposed business combination due to the failure to obtain approval of the shareholders of ATII and Forge Nano, or other conditions to closing in the Merger Agreement; (iv) the risk that the proposed business combination disrupts ATII's or Forge Nano's current plans and operations as a result of the announcement of the transactions; (v) risks related to Forge Nano's ability to realize the anticipated benefits of the proposed business combination, which may be affected by, among other things, competition and the ability of Forge Nano to grow and manage growth profitably following the proposed business combination; (vi) risks related to costs related to the proposed business combination; (vii) risks related to changes in applicable laws or regulations; (viii) risks related to Forge Nano's ability to successfully develop and deploy new technologies to address the needs of its customers, business, financial condition and results of operations; (ix) risks related to the effects of competition on Forge Nano's business; (x) risks related to the availability and cost of the raw materials necessary for the production of Forge Nano's products; (xi) risks related to Forge Nano's ability to meet the specifications and requirements of its customers or adequately provide them with effective support and services; (xii) risks related to delays in the construction and operation of production facilities; (xiii) risks related to intellectual property infringement, data protection, and other losses; (xiv) risks related to the amount of redemption requests made by ATII's public shareholders; (xv) risks related to Forge Nano's ability to operate effectively as a public company, including its ability to implement controls and procedures required for public companies following the business combination; (xvi) risks related to changes in domestic and foreign business, market, financial, political and legal conditions; (xvii) risks related to the possibility that ATII or Forge Nano may be adversely affected by other economic, business, and/or competitive factors and (xviii) other risks discussed in ATII's Annual Report on Form 10-K and that will be presented in the Registration Statement (as defined below), when available. There may be additional risks that ATII or Forge Nano presently do not know or that ATII or Forge Nano currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. Should one or more of the risks or uncertainties described in this Current Report on Form 8-K, or should underlying assumptions prove incorrect, actual results and plans could differ materially from those expressed or implied in any forward-looking statements. Additional information concerning these and other factors that may impact the operations and projections discussed herein can be found in ATII's periodic filings with the SEC, including ATII's Annual Report on Form 10-K and the Registration Statement, when available.

------

**MANAGEMENT COMMENTS**

"Over the past decade, we have built a differentiated platform and established commercial traction across semiconductor and energy storage markets," said **Paul Lichty, Co-Founder and Chief Executive Officer of Forge Nano**. "Domestic manufacturing of critical technologies is increasingly important to energy security and technology leadership, and our Atomic Armor™ platform is designed to improve performance and durability at the material level across applications ranging from lithium-ion batteries to advanced semiconductors. This transaction is expected to provide Forge Nano with the capital and market visibility to accelerate the next phase of our growth as we expand U.S. manufacturing of our nanocoating systems and lithium-ion batteries, deepen our role in the domestic battery supply chain and continue scaling the platform across additional industries."

**Long Long, Chief Executive Officer at Archimedes II**, added, "Forge Nano has developed a unique manufacturing technology with real commercial applications in two of the most important industrial markets today: semiconductors and energy storage. The Company combines a large patent portfolio, strategic industry partners and a growing domestic manufacturing footprint. We believe Forge Nano is well positioned to scale its platform and look forward to supporting the team as they enter the public markets."

**TRANSACTION OVERVIEW**

The business combination values Forge Nano at a pre-money, pre-merger equity of $1.2 billion. Additionally, the agreement includes a non-transferable earnout entitling holders to potential additional payments of up to $900 million in shares of the combined company tied to three specific trading price and revenue milestones. In addition to the $82.5 million in Series D financing, the Transaction could provide up to $342 million gross proceeds to Forge Nano, including:

● $242 million of cash held in the Archimedes II trust account as of April 9, 2026 (assuming no redemptions); and

● $100 million in capital committed by a leading fundamental institutional investor (assuming that the investor does not use any of this amount to instead buy SPAC shares in open market transactions).

Proceeds from the Transaction are expected to:

● Expand the production capacity of both semiconductor tools and battery cells;

● Accelerate Forge Nano's technology and product roadmap;

● Expand into new verticals such as pharmaceuticals, data centers and quantum computing; and

● Scale customer adoption and establish new ecosystem partnerships.

------

The boards of directors of Forge Nano and Archimedes II have each unanimously approved the proposed business combination and the Transaction is expected to close in the second half of 2026, subject to the approval of Archimedes II shareholders and other customary closing conditions, including the effectiveness of the registration statement on Form S-4 to be filed by an affiliate of Archimedes II and Forge Nano with the U.S. Securities and Exchange Commission (the "SEC"), the receipt of required regulatory approvals and approval by NASDAQ to list the securities of the combined company.
