Amendment Description ConnectOne Bancorp, Inc. (the “Company”) is filing this Amendment No. 1 on Form 10-K/A (“Amendment”) to amend its Annual Report on Form 10-K for the year ended December 31, 2024 (the “Form 10-K”), which was originally filed with the Securities and Exchange Commission on February 21, 2025. The purpose of this Amendment is to file Exhibit 10.14, which was inadvertently omitted from the originally filed Form 10-K.   This Amendment speaks as of the original filing date and does not reflect events occurring after the filing of the Form 10-K or modify or update disclosures that may be affected by subsequent events. No revisions are being made to the Company’s financial statements or any other disclosure contained in the Form 10-K.   This Amendment is an exhibit-only filing. Except for the inclusion of Exhibit 10.14, this Amendment does not otherwise update any exhibits as originally filed or previously amended.   In addition, as required by Rule 12b-15 under 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 to this Amendment pursuant to Rule 13a-14(a) and 15d-14(a) of the Exchange Act. The Company is not including certifications pursuant to Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) as no financial statements are being filed with this Amendment.
