Amendment Description ServisFirst Bancshares, Inc., a Delaware corporation, together with its subsidiaries, including ServisFirst Bank, the “Company”, which may also be referred to as “we”, “our”, “us”, “ServisFirst Bancshares”, and “ServisFirst”, is filing this Amendment No. 1 to Annual Report on Form 10-K/A (the “Amendment”) to our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, which was filed with the Securities and Exchange Commission on February 25, 2020 (the “Original Filing”). The Company is filing this Amendment solely for the purpose of including in Part II, Item 8 of its Annual Report on Form 10-K for the fiscal year ended December 31, 2019 the Consolidated Statement of Cash Flows for the fiscal year ended December 31, 2017, which was inadvertently omitted from the Original Filing.  This addition to the Consolidated Statements of Cash Flows does not affect Dixon Hughes Goodman LLP’s unqualified opinion on our consolidated financial statements included in the Original Form 10-K and this Amendment.   The Amendment includes the Consent of Independent Registered Public Accounting Firm in Exhibit 23 and updates Part IV, Item 15 of the Original Filing to include new certifications of our Chief Executive Officer and Chief Financial Officer as Exhibits 31.3, 31.4, 32.3 and 32.4.    Except as described above, no other changes have been made to the Original Filing. This Amendment does not reflect subsequent events that may have occurred after the original filing date of the Original Filing or modify or update in any way disclosures made in the Original Filing. Among other things, forward-looking statements made in the Original Filing have not been revised to reflect events that occurred or facts that became known to us after the filing of the Original Filing, and such forward-looking statements should be read in their historical context. Furthermore, this Amendment should be read in conjunction with the Original Filing and any other Company filings with the Securities and Exchange Commission made subsequent to the Original Filing.
