| Amendment Description | EverQuote, Inc. (the “Company”) is filing this Amendment No. 1 (“Amendment No. 1”) to its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2021 (the “Original Filing”), to reflect a change in the assessment of the effectiveness of the Company’s disclosure controls and procedures and the identification of material weaknesses in the Company’s internal control over financial reporting (“ICFR”). There has been no modification to the financial statements included in the Original Filing. In connection with the Original Filing, the Company’s management had concluded that, as of March 31, 2021, the Company’s disclosure controls and procedures were effective at the reasonable assurance level. Subsequent to the original evaluation, the Company’s management identified material weaknesses in the Company’s ICFR related to its information technology general controls for revenue-related information systems and, as a result, reconsidered its original conclusion regarding the effectiveness of its disclosure controls and procedures and determined that the Company did not, as of March 31, 2021, maintain effective disclosure controls and procedures. This reassessment was conducted and this conclusion was reached following an internal inspection by PricewaterhouseCoopers LLP (“PwC”), relating to the audits completed by PwC of the Company’s December 31, 2020 consolidated financial statements and ICFR as of that date. To address the material weaknesses in ICFR described above, the Company is developing a remediation plan and is currently implementing certain changes with respect to the identified control deficiencies. |
