AmBase Corporation is a Delaware holding company that was incorporated in 1975. The company’s principal activity is the management of its assets and liabilities. As of December 31 2025 its assets consisted primarily of cash and cash equivalents. AmBase holds an equity interest in a real estate joint venture that was formed to acquire and develop the property located at 105 through 111 West 57th Street in New York City. The investment in this joint venture was fully impaired in 2017 due to ongoing litigation concerning the property. Prior to the impairment the carrying value of the equity stake represented a substantial portion of the company’s total assets and net equity. The company also continues to pursue legal claims related to the former Carteret Savings Bank FA subsidiary and the supervisory goodwill settlement with the United States Government. At the end of 2025 AmBase employed four full time and two part time staff members. Its executive office is located at 7857 West Sample Road Suite 134 Coral Springs Florida 33065.

AmBase Corporation generates revenue mainly from interest earned on its cash and cash equivalents holdings. The company also receives proceeds from litigation settlements. Most notably in October 2012 the United States Government paid 180,650,000 directly to AmBase as part of the supervisory goodwill settlement agreement. The settlement payment was subject to tax consequences that the company has pursued through subsequent court proceedings. In August 2013 a senior judge ruled that the settlement agreement entitles AmBase to receive both the amount of tax consequences resulting from taxation of the damages award and the tax consequences of receiving the first component of the award. The court did not grant an additional amount for the second component at that time due to remaining uncertainty about the ultimate tax treatment of the settlement proceeds and the gross up and about the company’s future income. No regular operating revenue streams such as product sales or service fees are described in the filing. The company’s financial results are therefore driven by investment income and occasional legal recoveries.

AmBase Corporation does not operate as a producer of goods or services in a conventional industry. As a holding company its primary role is to hold and manage assets rather than to engage in competitive business activities. Consequently the firm does not hold a market share or competitive position that can be compared to operating peers. Its peers are other entities that hold investment portfolios or litigation trusts rather than companies that sell products. The lack of operating segments means there is no industry classification that reflects its core business. The company is subject to the reporting requirements of the Securities Exchange Act of 1934 and files periodic statements with the Securities and Exchange Commission. It does not maintain a website and provides copies of its reports to shareholders upon request by mail. Because the firm does not sell products or services any discussion of competitive advantages is limited to the efficiency of its asset management and the success of its legal recoveries.

AmBase Corporation’s counterparties are primarily governmental agencies and joint venture partners. In the supervisory goodwill litigation the company dealt with the United States Government the Federal Deposit Insurance Corporation as receiver and the Department of Justice. The real estate joint venture involved an unnamed partner for the development of the 111 West 57th Street property in New York City. Shareholders also receive communications through the company’s transfer agent Equiniti Trust Company LLC. The firm does not have a traditional consumer or commercial customer base because it does not sell products or services to end users. Stockholder inquiries regarding address changes lost certificates name changes and report requests are directed to Equiniti Trust Company LLC in Mendota Heights Minnesota. Copies of quarterly and annual reports can be obtained free of charge by mailing a request to the corporate office at 12 Lincoln Blvd Suite 202 Emerson New Jersey 07630. The company’s public filings are also accessible through the SEC’s EDGAR database and the SEC’s public reference room in Washington DC.
