Amendment Description EXPLANATORY NOTEN-able, Inc. (the “Company,” “we,” “us” or “our”) is filing this Amendment No. 1 on Form 10-K/A (this “Amendment”) to amend its Annual Report on Form 10-K for the fiscal year ended December 31, 2025, originally filed with the Securities and Exchange Commission (the “SEC”) on February 26, 2026 (the “Original Filing”), to amend and restate Part II, Item 9A, Controls and Procedures and revise the financial statements for the immaterial errors discussed below.Subsequent to the Original Filing, management identified a material weakness in our internal control over financial reporting that existed as of December 31, 2025, related to certain subscription arrangements for which revenue is recognized through manual processes outside our ERP system’s automated revenue recognition module, as described in Part II, Item 9A of this Amendment. As a result of the material weakness, management has concluded that our disclosure controls and procedures and our internal control over financial reporting were not effective as of December 31, 2025. Accordingly, Part II, Item 9A of the Original Filing is amended and restated in its entirety to reflect these revised conclusions, including a restated Management’s Annual Report on Internal Control over Financial Reporting, and to include the amended report of PricewaterhouseCoopers LLP (“PwC”), our independent registered public accounting firm, which expresses an adverse opinion on the effectiveness of our internal control over financial reporting as of December 31, 2025. Management’s Annual Report on Internal Control over Financial Reporting and PwC’s report on the effectiveness of internal control over financial reporting included in the Original Filing should no longer be relied upon. The material weakness resulted in immaterial errors of subscription revenue and related balance sheet accounts in our previously issued consolidated financial statements. We assessed these errors, individually and in the aggregate, and concluded that they were not material to any previously issued annual or interim consolidated financial statements. As described in Note 2, Summary of Significant Accounting Policies, and Note 17, Revision of Previously Issued Financial Statements, to the consolidated financial statements included in this 10-K/A, we revised our previously issued financial statements for the affected periods to correct these errors. Accordingly, this Amendment does not amend or restate the consolidated financial statements included in the Original Filing, and those consolidated financial statements, and PwC’s report thereon, may continue to be relied upon.This Form 10-K/A amends the following items of the Original Form 10-K:•Part I – Item 1A. Risk Factors.•Part II – Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.•Part II – Item 8. Financial Statements and Supplementary Data•Part II – Item 9A. Controls and Procedures.•Part IV – Item 15. Exhibits and Financial Statement Schedules.Except as described above, this Amendment does not amend, modify or update any other disclosure contained in the Original Filing and does not reflect events occurring after the date of the Original Filing. Accordingly, this Amendment should be read in conjunction with the Original Filing and with our filings with the SEC subsequent to the Original Filing, including our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2026 and June 30, 2026. In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended, this Amendment includes new certifications of our principal executive officer and principal financial officer and an updated Consent of Independent Registered Public Accounting Firm, which is being filed as Exhibit 23.1. Clawback Policy ConsiderationsIn connection with the errors identified, our management has performed a recovery analysis and determined there was no incentive-based compensation received by our executive officers during the relevant time frame that was based on a financial reporting measure impacted by the revisions. As such, there are no amounts to be recovered.
