| Amendment Description | This Amendment No. 1 (this “Amendment”) amends the Annual Report on Form 10-K for the year ended December 31, 2021, of LM Funding America, Inc. (the “Company,” “we”, or “our”), which we filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2022 (the “Original Filing”). This Amendment is being filed to amend and restate Items 10, 11, 12, 13, and 14 of Part III of the Form 10-K in their entirety to provide the information that the Company indicated that it would incorporate by reference from its Proxy Statement for the 2022 annual report of the stockholders in reliance on General Instruction G(3) to Form 10-K. In addition, as required by Rule 12b-15 under the Securities Exchange Action of 1934, as amended (the “Exchange Act”), this Amendment revises Item 15 of Part IV to include currently dated certifications by the Company’s principal executive officer and principal financial officer as exhibits to this Amendment and updates the Exhibit Index to reflect the inclusion of these certifications. Other than the items outlined above, this Amendment does not attempt to modify or update the Original Filing. This Amendment does not reflect events occurring after the date of the Original Filing or modify or update those disclosures that may be affected by subsequent events. Such subsequent matters are addressed in subsequent reports filed by the Company with the SEC. Accordingly, this Amendment should be read in conjunction with the Original Filing. Capitalized terms not defined in this Amendment have the meaning given to them in the Original Filing. |
