On July 15, 2022, the Audit Committee of the Board of Directors of Checkpoint Therapeutics, Inc. (the “Company”), unanimously voted to dismiss BDO USA, LLP (“BDO”) as the Company’s independent registered public accounting firm and to engage KPMG LLP (“KPMG”) as the Company’s independent registered public accounting firm for the 2022 fiscal year.

BDO’s reports on the Company’s financial statements for each of the fiscal years ended December 31, 2021 and December 31, 2020 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. During the Company’s fiscal years ended December 31, 2021 and December 31, 2020, and through the date of dismissal, there were no disagreements with BDO on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to the satisfaction of BDO, would have caused BDO to make reference to the subject matter of the disagreement in connection with its report.

During the fiscal years ended December 31, 2021 and December 31, 2020 and the subsequent period through the date of dismissal, there have been no reportable events within the meaning of Item 304(a)(1)(v) of Regulation S-K promulgated by the Securities and Exchange Commission (the “SEC”).

During the fiscal years ended December 31, 2021 and December 31, 2020 and the subsequent period to the date of its engagement, neither the Company nor anyone acting on its behalf has consulted with KPMG regarding (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report or oral advice was provided to the Company that KPMG concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue; (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K; or (iii) any reportable event within the meaning of Item 304(a)(1)(v) of Regulation S-K.

The Company provided BDO with a copy of this Form 8-K on July 20, 2022, and requested that BDO furnish it with a letter addressed to the SEC stating whether it agrees with the statements made by the Company in this Item 4.01 concerning BDO, and, if not, stating the respects in which it does not agree. The letter of BDO addressed to the SEC is attached hereto as Exhibit No. 16.1.
