Item 4.01. Changes in Registrant’s Certifying Accountant

(a) Dismissal of Independent Registered Public Accounting Firm

On August 8, 2021, the Audit Committee of the Board of Directors of Khosla Ventures Acquisition Co. II (the “Company”) approved the dismissal of Marcum LLP (“Marcum”) as the Company’s independent registered public accounting firm.

The reports of Marcum on the Company’s financial statements as of February 1, 2021 and for the period January 29, 2021 through February 1, 2021 and the Company’s balance sheet as of March 26, 2021 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles, other than an explanatory paragraph relating to the Company’s ability to continue as a going concern in the Company’s audited financial statements as of February 1, 2021 and for the period January 29, 2021 through February 1, 2021.

During the period January 29, 2021 through February 1, 2021 and through the date of termination, August 8, 2021, there were no “disagreements” with Marcum on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements if not resolved to the satisfaction of Marcum would have caused Marcum to make reference thereto in its reports on the financial statements for such period. During the period January 29, 2021 through February 1, 2021 and through August 8, 2021, there have been no “reportable events” (as defined in Item 304(a)(1)(iv) and Item 304(a)(1)(v) of Registration S-K), other than a material weakness in internal controls over financial reporting related to the inaccurate accounting for the value of private placement shares, underwriting discounts and over-allotment public shares issued subsequent to the closing of the Company’s initial public offering, as discussed further in the Company’s amended Quarterly Report on Form 10-Q/A filed on July 19, 2021.

The Company provided Marcum with a copy of the disclosure it is making herein in response to Item 304(a) of Regulation S-K, and requested Marcum furnish the Company with a copy of its letter addressed to the Securities and Exchange Commission (the “SEC”), pursuant to Item 304(a)(3) of Regulation S-K, stating whether or not Marcum agrees with the statements related to them made by the Company in this report. A copy of Marcum’s letter dated August 12, 2021 is attached as Exhibit 16.1 to this report.

(b) Newly Engaged Independent Registered Public Accounting Firm

On August 8, 2021, the Audit Committee approved the appointment of BDO LLP (“BDO”) as the Company’s new independent public accounting firm, effective immediately. Prior to engaging BDO, neither the Company, nor anyone on its behalf, consulted BDO regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered with respect to the consolidated financial statements of the Company, and no written report or oral advice was provided to the Company by BDO that was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a “disagreement” (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a “reportable event” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).
