EXPLANATORY NOTE

This Amendment No. 1 to the Quarterly Report on Form 10-Q (this “Amendment”) of CuriosityStream Inc. (the “Company” or “we”) amends the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2025, which was originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on November 13, 2025 (the “Original Q3 Form 10-Q”). We are filing this Amendment to revise Part II “Item 5. Other Information” of the Original Q3 Form 10-Q by adding Rule 10b5-1 trading arrangements entered into during the subject period by each of Theresa Cudahy, the Company’s Chief Operating Officer, and Jonathan Huberman, a director of the Company, which were inadvertently omitted from the disclosure included in the Original Q3 Form 10-Q.

In addition, as required by Rule 12b-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), new certifications by the Company’s principal executive officer and principal financial officer are filed herewith as Exhibits 31.1 and 31.2 to this Amendment, respectively, pursuant to Rule 13a-14(a) or 15d-14(a) of the Exchange Act. Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. In addition, because no financial statements have been included in this Amendment, we are not filing new, currently dated certifications pursuant to Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) (Section 906 of the Sarbanes-Oxley Act of 2002).

Except as specifically noted above, this Amendment does not modify or update disclosures in the Original Q3 Form 10-Q. This Amendment does not reflect events occurring after the filing of the Original Q3 Form 10-Q or modify or update any related or other disclosures, other than those discussed herein. Accordingly, this Amendment should be read in conjunction with the Original Q3 Form 10-Q and the Company’s other filings with the SEC subsequent to the filing of the Original Q3 Form 10-Q.
