Item 1.01 Entry Into A Material Definitive Agreement.

On May 28, 2026, FG Merger II Corp. (“FGMC”) and BOXABL Inc. (“BOXABL”), entered into an agreement with Atsion Opportunity Fund LLC – Series 2 (“Atsion”) for an OTC Equity Prepaid Forward Transaction (the “Forward Purchase Agreement”). For purposes of the Forward Purchase Agreement, “Counterparty” refers to FGMC prior to the consummation of the Business Combination and to FGMC (to be renamed “BOXABL Inc.”) following the consummation of the Business Combination. Immediately after entry into the Forward Purchase Agreement, the parties to the Forward Purchase Agreement entered into a Novation Agreement dated May 28, 2026 (the “Novation Agreement”), pursuant to which one-half of the Forward Purchase Agreement was novated to FG Capital Partners, LLC (“FGCP”, and collectively with Atsion, the “Seller”). FGCP is affiliated with Larry G. Swets, Jr., Hassan R. Baqar, Scott D Wollney and Richard E. Govignon, each an officer or director of the FGMC, resulting in the entry into the Novation Agreement being a related party transaction. Capitalized terms used herein but not otherwise defined shall have the meanings ascribed to such terms in the Forward Purchase Agreement.

The Forward Purchase Agreement is not being entered into to provide any capital to ensure that FGMC meets the minimum cash requirements for its initial business combination. Instead, FGMC entered into the Forward Purchase Agreement to provide access to potential additional growth capital in replacement of redeemed Trust assets.

Pursuant to the terms of the Forward Purchase Agreement, the Seller intended, but was not obligated, to purchase and hold up to 3,000,000 shares of FGMC common stock prior to the closing date of the Business Combination (the “Closing Date”).

The Forward Purchase Agreement provides that Seller shall be prepaid an aggregate cash amount (the “Prepayment Amount”) equal to the product of (i) the number of shares as set forth in a Pricing Date Notice and (ii) the per share redemption price payable to redeeming shareholders in connection with the Business Combination (the “Initial Price”). Counterparty will pay to the Seller the Prepayment Amount directly from the Trust Account no later than the earlier of (a) one business day after the Closing Date, and (b) the date any assets from the Trust Account are disbursed in connection with the Business Combination.

From time to time and on any date following the Closing Date (any such date, an “OET Date”), the Seller may terminate the Forward Purchase Agreement in whole or in part with respect to any Shares upon written notice to Counterparty (an “OET Notice”), specifying the number of Shares by which the number of Shares shall be reduced (such quantity, the “Terminated Shares”). “Terminated Shares” includes (i) Shares specified in an OET Notice and (ii) any Recycled Shares sold by Seller during the term of the Transaction, unless Counterparty and Seller agree in writing to an alternative sale reconciliation procedure. Seller will pay to Counterparty an amount equal to the product of (x) the number of Terminated Shares and (y) the Reference Price in respect of such OET Date (the “Termination Price”) (an “Early Termination Obligation”). The Reference Price is initially $10.00, and may be reduced by Counterparty one time in any twenty-one-day period. The effect of an OET Notice will be to reduce the Number of Shares by the number of Terminated Shares specified in such OET Notice with effect as of the related OET Date.

The Forward Purchase Agreement valuation date shall be 90 days following the closing of the Business Combination (the “Valuation Date”), although Counterparty shall have the right to extend the Valuation Date for an additional 90 days up to two times (for up to 180 additional days in total) upon ten Exchange Business Days’ notice to the Seller. On the Cash Settlement Payment Date, which is the tenth trading day immediately following the Maturity Date (as described below), the Seller will remit to the Counterparty an amount equal to (a) the product of (i) the Number of Shares as of the Valuation Date, multiplied by (ii) the average daily VWAP Price over the Valuation Period, less (b) the Settlement Amount Adjustment. The Settlement Amount Adjustment is a cash amount equal to the product of (i) the Number of Shares as of the Valuation Date, multiplied by (ii) $0.80. The Valuation Period commences on the first Exchange Business Day immediately following the Valuation Date and ends 15 trading days after such date.

Seller agreed to waive any redemption rights under the Counterparty’s Certificate of Incorporation, as amended, with respect to the Shares during the term of the Forward Purchase Agreement. Such waiver may reduce the number of shares of Counterparty common stock redeemed in connection with the Business Combination, and such reduction could alter the perception of the potential strength of the Business Combination. The Forward Purchase Agreement has been structured, and all activity in connection with such agreement has been undertaken, to comply with the requirements of all tender offer regulations applicable to the Business Combination, including Rule 14e-5 under the Securities Exchange Act of 1934, as amended.

The foregoing summary of the Forward Purchase Agreement is qualified in its entirety by reference to the full text of the Forward Purchase Agreement, which is filed as Exhibit 10.1 hereto and is incorporated herein by reference.

We have based these forward-looking statements on current expectations and projections about future events. These statements include: projections of market opportunity and market share; estimates of customer adoption rates and usage patterns; projections of development and commercialization costs and timelines; expectations regarding BOXABL’s ability to execute its business model and the expected financial benefits of such model; expectations regarding BOXABL’s ability to attract, retain, and expand its customer base; BOXABL’s deployment of Casita; BOXABL’s expectations concerning relationships with strategic partners, suppliers, governments, regulatory bodies and other third parties; future ventures or investments in companies, products, services, or technologies; development of favorable regulations and government incentives affecting BOXABL’s markets; the potential benefits of the proposed transaction and expectations related to its terms and timing; BOXABL’s plans to reorganize its operations into a flatter structure and to enhance cross-functional integration through increased use of real-time data and analytics; and the potential for BOXABL to increase in value.

These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by such statements. Such risks and uncertainties include: that BOXABL is pursuing an emerging technology, faces significant technical challenges and may not achieve commercialization or market acceptance; BOXABL’s historical net losses and limited operating history; BOXABL’s expectations regarding future financial performance, capital requirements and unit economics; BOXABL’s use and reporting of business and operational metrics; BOXABL’s competitive landscape; BOXABL’s dependence on members of its senior management and its ability to attract and retain qualified personnel; the capital requirements of BOXABL’s business plans and the potential need for additional future financing; BOXABL’s ability to manage growth and expand its operations; potential future acquisitions or investments in companies, products, services or technologies; BOXABL’s reliance on strategic partners and other third parties; BOXABL’s ability to maintain, protect and defend its intellectual property rights; risks associated with privacy, data protection or cybersecurity incidents and related regulations; the use and regulation of artificial intelligence and machine learning; uncertainty or changes with respect to laws and regulations; uncertainty or changes with respect to taxes, trade conditions and the macroeconomic environment; the combined company’s ability to maintain internal control over financial reporting and operate a public company; the possibility that required regulatory approvals for the proposed transaction are delayed or are not obtained, which could adversely affect the combined company or the expected benefits of the proposed transaction; the risk that shareholders of FGMC could elect to have their shares redeemed, leaving the combined company with insufficient cash to execute its business plans; the occurrence of any event, change, or other circumstance that could give rise to the termination of the Merger Agreement; the outcome of any legal proceedings or government investigations that may be commenced against BOXABL or FGMC; failure to realize the anticipated benefits of the proposed transaction; the ability of FGMC or the combined company to issue equity or equity-linked securities in connection with the proposed transaction or in the future; and other factors described in FGMC’s filings with the SEC. Additional information concerning these and other factors that may impact such forward-looking statements can be found in filings and potential filings by BOXABL, FGMC or the combined company resulting from the proposed transaction with the SEC, including under the heading “Risk Factors.” If any of these risks materialize or assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements.

While BOXABL and FGMC may elect to update these forward-looking statements at some point in the future, they specifically disclaim any obligation to do so. Accordingly, undue reliance should not be placed upon these statements.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject.
