Item 4.01. Changes in Registrant’s Certifying Accountant.

On July 15, 2025, PricewaterhouseCoopers LLP (“PwC”) notified Spire Global, Inc. (the “Company”) of its resignation as the Company’s independent registered public accounting firm for the year-end audit for the fiscal year ending December 31, 2025. The resignation will be effective upon the filing of the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2025 (the “Quarterly Report”) with the Securities and Exchange Commissions (the “SEC”). The Company will file an amendment to this Current Report on Form 8-K no later than four business days of filing the Quarterly Report with the specific date of termination and an update to the disclosures required by Item 304(a) of Regulation S-K through that date.

The audit reports of PwC on the Company’s consolidated financial statements for the Company’s fiscal years ended December 31, 2024 and 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 each such report contained an explanatory paragraph expressing substantial doubt about the Company’s ability to continue as a going concern.

During the Company’s fiscal years ended December 31, 2024 and 2023, and the subsequent interim period through the date of this Current Report on Form 8-K, there were no disagreements (within the meaning of Item 304(a)(1)(iv) of Regulation S-K and related instructions) between the Company and PwC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of PwC, would have caused PwC to make reference to the subject matter of the disagreements in connection with PwC’s reports on the Company’s financial statements.

During the Company’s fiscal years ended December 31, 2024 and 2023, and the subsequent interim period through the date of this Current Report on Form 8-K, the only “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K) were PwC’s communication to the Company of the material weakness in disclosure controls and procedures disclosed in the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2024 (the “2024 Form 10-K/A”), and the material weaknesses in internal control over financial reporting disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Form 10-K”), the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2023 (the “2023 Form 10-K/A”), and the 2024 Form 10-K/A. Descriptions of the foregoing material weaknesses under the headings (i) “Management's Report on Internal Control over Financial Reporting” in Part II, Item 9A. “Controls and Procedures” in the 2023 Form 10-K/A and the 2024 Form 10-K/A, (ii) “Evaluation of Disclosure Controls and Procedures” in Part II, Item 9A. “Controls and Procedures” in the 2024 Form 10-K/A, and (iii) “Material Weaknesses in Internal Control over Financial Reporting” in Part II, Item 9A. “Controls and Procedures” in the 2023 Form 10-K are incorporated herein by reference.

The Audit Committee is in the process of conducting a request for proposal process to identify an independent registered public accounting firm to replace PwC. The Audit Committee discussed with PwC the reportable events described above, and the Company has authorized PwC to respond fully to the inquiries of the Company’s successor independent registered public accounting firm concerning these reportable events.

The Company has provided PwC with a copy of the disclosures made in this Current Report on Form 8-K prior to its filing with the SEC and requested that PwC furnish the Company with a letter addressed to the SEC stating whether PwC agrees with the statements made herein. A copy of PwC’s letter is attached as Exhibit 16.1 to this Current Report on Form 8-K.

Item 8.01. Other Events.

Because of additional accounting activities required to finalize the Company’s condensed consolidated financial statements as of and for the three and six months ended June 30, 2025, including as a result of the closing of the sale of the Company’s maritime business to Kpler Holding SA, the Company does not currently expect to be able to file the Quarterly Report on or before the deadline for such filing or within the extension period of five calendar days permitted under Rule 12b-25 of the Securities Exchange Act of 1934, as amended.
