| Amendment Description | EverQuote, Inc. (the “Company”) is filing this Amendment No. 1 (“Amendment No. 1”) to its Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the “Original Filing”), to reflect a change in the assessment of the effectiveness of 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 December 31, 2020, the Company’s ICFR was effective and PricewaterhouseCoopers LLP (“PwC”) concluded that the Company maintained, in all material respects, effective ICFR as of December 31, 2020, as reflected in PwC’s report that was included in the Original Filing. 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 ICFR and determined that the Company did not, as of December 31, 2020, design and maintain effective ICFR. This reassessment was conducted and this conclusion was reached following an internal inspection by 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. | ||
