Amendment Description This Amendment No. 1 on Form 10-K/A (this “Amendment”) is being filed by SeaChange International, Inc., a Delaware corporation (“SeaChange”), to amend the Annual Report on Form 10-K for the year ended January 31, 2022 filed by SeaChange with the Securities and Exchange Commission (the “SEC”) on April 8, 2022 (the “Original Report”) to include the information required to be disclosed by Part III, Items 10 through 14 of Form 10-K. This information was previously omitted from the Original Report in reliance on General Instruction G(3) to Form 10-K. In accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Part III, including Items 10 through 14 of the Original Report, is hereby amended and restated in its entirety.   This Amendment consists solely of the preceding cover page, this explanatory note, the information required by Part III, Items 10, 11, 12, 13, and 14 of Form 10-K, a signature page and certifications required to be filed as exhibits. 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. We are not including the certifications under Section 906 of the Sarbanes-Oxley Act of 2002 as no financial statements are being filed with this Amendment.   This Amendment does not amend, update or change any other item or disclosure in the Original Report. Therefore, this Amendment should be read in conjunction with the Original Report and SeaChange’s other filings made with the SEC subsequent to the filing of the Original Report.
