Risk factors and legal proceedings

The risks AmBase Corp names in Item 1A of its 10-K filed Mar 30, 2026: 19 risks under these headings, as written.4

  • Operating Risks
  • Going Concern
  • The Company has incurred operating losses over the last several years and may not be able to achieve profitability.
  • The Company is in a competitive business.
  • We are a party to legal proceedings relating to our equity interest in the joint real estate venture 111 West 57th Partners, and may become subject to additional litigation in the future, all of which continue to have an adverse effect on our financial condition, results of operations, cash flow and per share trading price of our common stock.
  • Illiquidity of real estate limits our ability to act quickly.
  • Property ownership through equity investments and/or in joint ventures could subject us to the differing business objectives of our co-venturers.
  • We may be unable to identify suitable properties for equity investments and acquisitions and any new investments and acquisitions may fail to perform as expected and subject us to new risks, including risks created by geographic concentration.
  • Fluctuations in the local market in which the Company’s equity investment in a development property is located may adversely impact the Company’s financial condition and operating results.
  • The Company may not be able to insure certain risks economically.
  • Development and redevelopment activities may be delayed, not completed, and/or not achieve expected results.
  • We are dependent on our key personnel whose continued service is not guaranteed and the loss of whose service could have a material adverse effect on our business.
The other 9 risks
  • Changes in the composition of the Company’s assets and liabilities through acquisitions, divestitures or corporate restructuring may affect the Company’s results.
  • Terrorist attacks and other acts of violence or war may affect the market, on which the Company’s common stock trades, the markets in which the Company operates the Company’s operations and the Company’s results of operations.
  • The Company is subject to risks inherent in owning, developing and leasing real estate.
  • Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer.
  • The Company may not be able to generate sufficient taxable income to fully realize the Company’s deferred tax asset.
  • Because the Company from time to time maintains a majority of its assets in cash and/or securities, the Company may in the future be deemed to be an investment company under the Investment Company Act of 1940 resulting in additional costs and regulatory burdens.
  • Anti-takeover Risks
  • Our amended and restated shareholder rights plan may delay or prevent an acquisition of us that shareholders may consider favorable or may prevent efforts by our shareholders to change our directors or our management, which could decrease the value of your common shares.
  • Outbreaks of highly infectious or contagious diseases may, materially and adversely impact the business, income, cash flow, results of operations and financial condition of the Company, including the 111 West 57th Property.
  • We face possible risks associated with the physical effects of climate change.

Legal proceedings
