Risk factors and legal proceedings

The risks Constellation Acquisition Corp I names in Item 1A of its 10-K filed Apr 15, 2026: 4 risks under these headings, as written.4

  • We may be unable to obtain additional financing to complete our initial business combination or to fund the operations and growth of a target business, which could compel us to restructure or abandon a particular business combination.
  • NYSE delisted Constellation’s securities from its exchange after Constellation’s voluntary request which could limit investors’ ability to make transactions in its securities and subject Constellation to additional trading restrictions.
  • If we are deemed to be an investment company for purposes of the Investment Company Act, we would be required to institute burdensome compliance requirements and our activities would be severely restricted. As a result, in such circumstances, unless we are able to modify our activities so that we would not be deemed an investment company, we may abandon our efforts to complete an initial Business Combination and instead liquidate Constellation.
  • We may not be able to complete the Business Combination since such initial business combination may be subject to regulatory review and approval requirement, including foreign investment regulations and review by government entities such as the Committee on Foreign Investment in the United States (“CFIUS”), or may be ultimately prohibited.

Legal proceedings

To the knowledge of our management, there is no material litigation, arbitration or governmental proceeding currently pending against us or any members of our management team in their capacity as such.
