Item 1.01

Entry Into a Material Definitive Agreement.

On March 2, 2026, AmBase Corporation, a Delaware corporation (“AmBase” or the “Company”) and Mr. Richard A. Bianco, the Company’s Chairman, President and Chief Executive Officer (“RAB”) entered into a Litigation Funding Agreement (the “RAB 2026 LFA”), pursuant to which the Company and RAB agreed that RAB will provide up to an aggregate initial amount of Six Million Dollars ($6,000,000) (plus such additional amounts as may be necessary from time to time and as agreed to by the Company and RAB at such time), as further described in the Company’s Current Report on Form 8-K as filed with the SEC on March 4, 2026, and incorporated herein by reference. On July 30, 2026, the Company and RAB entered into a letter agreement (the “Letter Agreement”) pursuant to which RAB paid the Company an additional $1,000,000, for use by the Company for working capital needs and continuing litigation related expenses with respect to the 111 West 57^th Property. The additional amounts contributed by RAB were made pursuant to the same terms and conditions of the RAB 2026 LFA. A copy of the Letter Agreement is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

As previously disclosed in the reports filed by the Company under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company’s financial statements have expressed a qualification about the Company’s ability to continue as a going concern.

In order to continue as a going concern and fund anticipated future litigation expenses, the Company will need to raise additional capital. The Company continues to explore all possible strategic alternatives to meet is capital needs, including but not limited to, raising additional capital through the sale of equity or debt securities or long-term borrowings, which may include additional borrowings from affiliates of the Company, financial institutions or other stockholders of the Company, litigation funding agreements from affiliates of the Company, financial institutions, other stockholders of the Company, or other third parties, and seeking recoveries from various sources. The Company intends for any sales of debt or equity securities or any borrowings from any parties to be on market terms to be agreed upon at the time of any transaction. However, there can be no assurance that the Company will be able to raise capital or obtain financing on terms acceptable to the Company, if at all.

As noted above, the Company continues to explore all possible strategic alternatives to meet its capital needs. Litigation funding agreements are special types of financing arrangements that generally are structured so that the litigation funder would receive back their initial funding amount first (i.e. before any recovery is received by the Company), plus an additional multiple ranging from 1.0 times to 3.5 times the amount funded (depending on various factors), plus depending on the funder, additional fees, expenses, interest and potentially an additional percentage of the total recovery received. If the Company continues to source capital through one or more litigation funding agreements, there can be no assurance that the Company would be able to secure any such additional litigation funding on acceptable terms or at all.

While the Company’s management is evaluating future courses of action to protect and/or recover the value of the Company’s equity investment in the 111 West 57^th Property, the adverse developments make it uncertain as to whether any such courses of action will be successful. Any such efforts are likely to require sustained effort over a period of time and substantial additional capital. The Company continues to explore all possible strategic alternatives to meet is capital needs, including but not limited to, raising additional capital through the sale of equity or debt securities or long-term borrowings, which may include additional borrowings from affiliates of the Company, financial institutions or other stockholders of the Company, litigation funding agreements from affiliates of the Company, financial institutions, other stockholders of the Company, or other third parties, and seeking recoveries from various sources. Inability to recover all or most of such value would, in all likelihood, have a material adverse effect on the Company’s financial condition and future prospects. The Company can give no assurances with regard if it will prevail with respect to any of its claims.

With respect to its disputes and litigation relating to its interest in the 111 West 57th Property, the Company is pursuing, and will continue to pursue, other options to realize the Company’s investment value, various legal courses of action to protect its legal rights, recovery of its asset value from various sources of recovery, as well as considering other possible economic strategies, including the possible sale of the Company’s interest in and/or rights with respect to the 111 West 57^th Property; however, there can be no assurance that the Company will prevail with respect to any of its claims.

The information in this Current Report on Form 8-K should be read in conjunction with the Company’s annual report on Form 10-K for the year ended December 31, 2025, and the Company’s reports filed with the SEC (collectively, the “Prior Periodic Reports”). A more complete discussion of the Company's financial condition and results of operations are also set forth in the Prior Periodic Reports, including without limitation the disclosures under the headings “Risk Factors” and “Cautionary Statement for Forward-Looking Information.”
