Item 4.02. Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review.

In the unaudited interim financial statements for the quarter ended September 30, 2021 of Thayer Ventures Acquisition Corporation (the “Company”), previously filed with the Securities and Exchange Commission (the “SEC”) in the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2021 (the “Third Quarter 10-Q”), the Company concluded that it should classify all Class A common stock subject to possible redemption in temporary equity in accordance with SEC guidance on redeemable equity instruments, codified in Accounting Standards Codification 480-10-S99, Distinguishing Liabilities from Equity (“ASC 480-10-S99”). In previous periods, the Company had classified a portion of its Class A common stock in total stockholders’ equity. In the Third Quarter 10-Q, the Company determined to present this revision in a prospective manner in all future filings. Under this approach, the Company’s previously issued financial statements would not be amended, but financial statements presented in future filings would be recast to be consistent with the presentation for the unaudited interim financial statements as of September 30, 2021.

On November 19, 2021, the Audit Committee (the “Audit Committee”) of the board of directors of the Company, after considering the recommendations of, and in consultation with management, concluded that the Company’s previously issued audited financial statements as of December 31, 2020 and for the period from July 31, 2020 (inception) through December 31, 2020, as contained in the Company’s Annual Report on Form 10-K filed with the SEC on March 24, 2021, as amended on May 19, 2021 (as amended, the “Form 10-K”), and the Company’s previously issued unaudited interim financial statements contained in the Company’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2021 and June 30, 2021, originally filed with the SEC on May 28, 2021 and August 16, 2021, respectively, should no longer be relied upon due to such change in classification of the Company’s Class A common stock subject to possible redemption in accordance with ASC 480-10-S99.

As a result, the Company intends to file an amendment to its Form 10-K to reclassify all of the Company’s Class A common stock as of December 31, 2020 as described above, and the corresponding changes to the financial statement items as of and for the period ended December 31, 2020 will be set forth in restated financial statements included in the amended Form 10-K. The Company also intends to file an amendment to its Third Quarter 10-Q to disclose in footnotes to the financial statements therein a summary of the impact of the reclassification of its Class A common stock as of and for the quarters ended March 31, 2021 and June 30, 2021. The Company does not intend to file amendments to its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2021 and June 30, 2021.

The Company’s revised accounting for its Class A common stock subject to redemption in the planned restatement of the audited financial statements as of and for the period ended December 31, 2020 will not have any effect on the Company’s previously reported assets, including cash and cash equivalents. The impact of the revisions is limited to reclassification of amounts from total stockholders’ equity to Class A common stock subject to possible redemption. In connection with the change in presentation for the Class A common stock subject to possible redemption, the Company will revise its earnings per share calculation to allocate income and losses shared pro rata between the two classes of shares.

The Audit Committee and management have discussed the matters disclosed in this Current Report on Form 8-K with the Company’s independent registered public accounting firm, WithumSmith+Brown, PC.

In connection with the restatement, management re-evaluated the effectiveness of the Company’s disclosure controls and procedures as of September 30, 2021. Management concluded that the Company’s disclosure controls and procedures were not effective as of September 30, 2021, due to a material weakness in internal control over financial reporting with respect to the accounting for complex equity instruments, solely as a result of the misclassification of a portion of the shares of Class A common stock as permanent equity instead of as temporary equity.
