(a) Dismissal of Independent Registered Public Accounting Firm
On September 30, 2025, the Audit Committee (the “Audit Committee”) of the Board of Directors (the “Board”) of Equillium, Inc. (the “Company”) approved dismissal of KPMG LLP (“KPMG”) as the Company’s independent registered public accounting firm, with such dismissal to become effective on September 30, 2025.
KPMG’s audit reports on the Company’s consolidated financial statements as of and for the years ended December 31, 2024 and 2023 did not contain any adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles, except as follows: KPMG’s report on the consolidated financial statements of the Company as of and for the years ended December 31, 2024 and 2023 contained a separate paragraph stating that “The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered significant operating losses and negative cash flows from operations that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.”
During the Company’s fiscal years ended December 31, 2024 and 2023 and the subsequent interim period through September 30, 2025: (1) there were no “disagreements” (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304) with KPMG 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 KPMG, would have caused KPMG to make reference to the subject matter of such disagreements in connection with its reports on the consolidated financial statements for such periods and (2) there were no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K).
The Company provided KPMG with a copy of this Current Report on Form 8-K prior to its filing with the Securities and Exchange Commission (the “SEC”) and requested that KPMG furnish the Company with a letter addressed to the SEC stating whether KPMG agrees with the statements made by the Company in this Current Report on Form 8-K and, if not, stating the respects, if any, in which KPMG does not agree with such statements. A copy of the letter from KPMG is filed with this Current Report on Form 8-K as Exhibit 16.1.
(b) Engagement of New Independent Registered Public Accounting Firm
On September 30, 2025, the Audit Committee approved the engagement of Crowe LLP (“Crowe”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025, subject to the execution of an engagement letter and completion of Crowe’s standard client acceptance procedures. Upon the execution of an engagement letter with Crowe, the Company will file an amendment to this Current Report on Form 8-K with the specific date of engagement and an update to the disclosures required by Item 304(a)(2) of Regulation S-K through that date.

In connection with Dr. Connelly’s and Dr. Manian’s resignations, the Board reduced the size of the Board from nine directors to seven directors.
On September 30, 2025, the Board, upon recommendation of the Nominating and Corporate Governance Committee of the Board (the “Nominating Committee”), appointed Charles McDermott, as a member of the Company’s Audit Committee to fill the vacancy created by Dr. Manian’s resignation, as of the Effective Date. The Audit Committee is now composed of Martha Demski (Chair), Charles McDermott, and Barbara Troupin, M.D.
On September 30, 2025, the Board, upon recommendation of the Nominating Committee, appointed Mark Pruzanski, M.D. to serve as the chairperson of the Compensation Committee, as of the Effective Date. The Compensation Committee is now composed of Dr. Pruzanski (Chair) and Ms. Demski.
On September 30, 2025, Daniel M. Bradbury agreed to transition from Executive Chairman of the Company to Chairman of the Board effective as of the Effective Date.
(c) Appointment of President
On September 30, 2025, the Board appointed Dr. Connelly, the Company’s Chief Scientific Officer, as the Company’s President. There will be no change to Dr. Connelly’s compensation arrangements with the Company at this time.
The biography of Dr. Connelly is incorporated herein by reference to the section titled “Proposal 1: Election of Directors – Class I Director Nominees for Election at the Annual Meeting” of the Company’s definitive proxy statement on Schedule 14A, filed with the SEC on April 10, 2025, as revised on April 30, 2025.
Dr. Connelly has no family relationships with any of the Company’s directors or executive officers, and he has no direct or indirect material interest in any transaction required to be disclosed pursuant to Item 404(a) of Regulation S-K. In addition, there are no arrangements or understandings between Dr. Connelly and any other person pursuant to which he was selected to his role with the Company.
