Amendment Description	This Amendment No. 1 on Form 10-K/A (this “Amendment”) amends the Annual Report on Form 10-K for the fiscal year ended December 31, 2025 of Fluent, Inc. (the “Company”), as originally filed with the Securities and Exchange Commission (“SEC”) on March 31, 2026 (the “Original Form 10-K”). This Amendment is being filed to amend: (i) Part III of the Original Form 10-K to include the information required by Part III of Form 10-K that was previously omitted from the Original Form 10-K in reliance on General Instruction G(3) to Form 10-K because a definitive proxy statement containing such information will not be filed within 120 days after the end of the Company’s fiscal year ended December 31, 2025; and (ii) Part IV of the Original Form 10-K to add new certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and in accordance with Rule 13a-14(a) under the Exchange Act. In addition, the reference on the cover of the Original Form 10-K to the incorporation by reference to portions of the Company’s definitive proxy statement into Part III of the Original Form 10-K is hereby deleted. Except as otherwise expressly noted herein, this Amendment does not amend, modify, or otherwise update any other information in the Original Form 10-K, nor does it reflect events that may have occurred after the filing date of the Original Form 10-K. Accordingly, this Amendment should be read in conjunction with the Original Form 10-K and with the Company’s filings with the SEC subsequent to the filing of the Original Form 10-K.
