Item 4.01      Changes in Registrant’s Certifying Accountant.  

(a) Dismissal of Independent Registered Public Accounting Firm

On July 16, 2025, the audit committee (the “ Audit Committee”) of the board of directors of Plus Therapeutics, Inc. (the “ Company”) dismissed BDO USA, P. C. (“ BDO”) as the Company’s independent registered public accounting firm.

BDO’s audit reports on the Company’s consolidated financial statements for the fiscal years ended December 31, 2024 and December 31, 2023 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, except that the reports included an explanatory paragraph relating to substantial doubt about the Company’s ability to continue as a going concern.

During the Company’s two most recent fiscal years and the subsequent interim period through July 16, 2025, there were no (i) disagreements as defined in Item 304(a)(1)(iv) of RegulationS-Kunder the Exchange Act of 1934, as amended (the “ Exchange Act”) and the related instruction thereto, between the Company and BDO on any matter of accounting principles or practice, financial statement disclosure, or auditing scope of procedure, which disagreements, if not resolved to BDO’s satisfaction, would have caused BDO to make reference to the subject matter of the disagreements in connection with their reports or (ii) reportable events (as defined in Item 304(a)(1)(v) of RegulationS-Kunder the Exchange Act), except for the material weakness in the Company’s internal control over financial reporting as of December 31, 2023, as previously disclosed in Item 9A of the Company’s Annual Report on Form10-Kfor the year ended December 31, 2023, stemming from the conclusion that the Company’s disclosure controls and procedures (as defined in Rules13a-15(e)and15d-15(e)under the Exchange Act) were not effective at the reasonable assurance level due to a material weakness in the Company’s internal control over the application of appropriate accounting principles to significant and unusual grant revenue transactions as of December 31, 2023. The Audit Committee discussed this matter with BDO, and the Company has authorized BDO to respond fully to any inquiries of CBIZ CPAs P. C. (“ CBIZ”) with respect to this matter.
