Item 2.02. Results of Operations and Financial Condition

The information included in Item 4.02 of this Form 8-K regarding the completed fiscal periods noted below is incorporated by reference in this Item 2.02.

Item 4.02 Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review.

In connection with the preparation of the third quarter 2022 condensed consolidated financial statements of Spire Global, Inc. (the “Company” or “Spire”), an error was identified related to the accounting for the fair value of the Company’s contingent earnout liability for the quarter and nine months ended September 30, 2021, quarter and year ended December 31, 2021, quarter ended March 31, 2022, and quarter and six months ended June 30, 2022 (the “Affected Periods”). The error resulted in the misstatement of the contingent earnout liability balance as of the end of each Affected Period. The error also resulted in the reported change in fair value of contingent earnout liability, total other income (expense), net, net income (loss), and basic and diluted net income (loss) per share for the Affected Periods being misstated.

On October 20 and 22, 2022, the audit committee of the board of directors of Spire, after discussion with the Company’s management and with the Company’s independent registered public accounting firm, concluded that the Company’s previously issued unaudited condensed consolidated financial statements as of and for the quarter and nine months ended September 30, 2021, quarter ended December 31, 2021, quarter ended March 31, 2022, and quarter and six months ended June 30, 2022, and the Company’s previously issued audited consolidated financial statements as of and for the year ended December 31, 2021, filed with the Securities and Exchange Commission in the respective Quarterly Reports on Form 10-Q for such quarterly periods (the “Form 10-Qs”) and in the Annual Report on Form 10-K (the “Form 10-K”) for the fiscal year ended December 31, 2021, and included in any reports, related earnings releases, investor presentations or similar communications of the Company’s financial results, should no longer be relied upon. The Company intends to restate its consolidated financial statements for the Affected Periods and include them in amended Form 10-Q/As and an amended Form 10-K/A to be filed with the Securities and Exchange Commission. The Company is working to complete such restatements as soon as practicable.

The error was identified when the Company discovered that an incorrect number had been used in the calculation of the fair value of the contingent earnout liability in each of the Affected Periods. As a result, the fair value of the Company’s contingent earnout liability, change in fair value of contingent earnout liability, total other income (expense), net, net income (loss), and basic and diluted net income (loss) per share were all misstated for the Affected Periods.

The following tables show the preliminary estimated impact of the error on the Company’s contingent earnout liability, change in fair value of contingent earnout liability, total other income (expense), net, and net income (loss) for the Affected Periods as compared to previously issued financial statements for such Affected Periods. The following estimates of the error amounts, and the resulting restated amounts, are preliminary, unaudited and subject to further change in connection with the completion of the amended Form 10-Q/As and amended Form 10-K/A.

The preliminary unaudited estimates of the error related to the contingent earnout liability are as follows (in thousands):

*Contingent earnout liability recognized upon closing of the merger was overstated by $20,121 thousand.

The preliminary unaudited estimates of the error related to the change in fair value of the contingent earnout liability are as follows (in thousands):

The preliminary unaudited estimates of the error related to total other income (expense), net are as follows (in thousands):

The preliminary unaudited estimates of the error related to net income (loss) are as follows (in thousands):

The errors do not impact the Company’s previously reported revenue, cash flows or cash positions in any period. Furthermore, the Company’s previously reported non-GAAP financial measures of operating loss, net loss and Adjusted EBITDA, as well as the business metric annual recurring revenue (“ARR”) are not impacted by this matter. Neither the changes nor the restatements of the Company’s quarterly and annual financial statements affect the Company’s compliance with the financial covenants contained in its outstanding debt obligations or compliance with any other material agreement of the Company or its subsidiaries.

In connection with the restatements discussed above, the Company’s management has re-evaluated the effectiveness of the Company’s disclosure controls and procedures as of September 30, 2021, December 31, 2021, March 31, 2022 and June 30, 2022 and based on that evaluation, the Company’s management has concluded its disclosure controls and procedures remained ineffective due to the unremediated material weaknesses previously disclosed in Item 9A “Controls and Procedures” of the Company’s Form 10-K for the fiscal year ended December 31, 2021, as well as the identification of an additional material weakness in internal control over financial reporting related to this matter. Management’s conclusions regarding the impacts of the restatements on internal control over financial reporting will be included in the amended Form 10-Q/A for the periods ended September 30, 2021, March 31, 2022, and June 30, 2022, and in the amended Form 10-K/A for the year ended December 31, 2021.

The audit committee and the Company’s management have discussed the matters disclosed on this Current Report on Form 8-K with the Company’s independent registered public accounting firm, PricewaterhouseCoopers LLP.
