Basis of Presentation

The condensed consolidated financial statements and accompanying notes are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and regulations of the U.S. Securities and Exchange Commission (the "SEC") for interim financial reporting.

Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to rules and regulations applicable to interim financial reporting. The unaudited condensed consolidated financial statements were prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, contain all adjustments, consisting of normal recurring adjustments necessary for a fair statement of its financial position, results of operations and cash flows for the periods indicated. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements included within the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

The information as of December 31, 2022 included on the condensed consolidated balance sheets was derived from the Company’s audited consolidated financial statements. All intercompany accounts and transactions have been eliminated in consolidation.

Results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2023.

Liquidity Risks and Uncertainties

Since inception, the Company has been engaged in developing its product offerings, raising capital, and recruiting personnel. The Company’s operating plan may change as a result of many factors currently unknown and there can be no assurance that the current operating plan will be achieved in the time frame anticipated by the Company, and it may need to seek additional funds sooner than planned. If adequate funds are not available to the Company on a timely basis, it may be required to delay, limit, reduce, or terminate certain commercial efforts, or pursue merger or acquisition strategies, all of which could adversely affect the holdings or the rights of the Company’s stockholders.

The Company has a history of operating losses and negative cash flows from operations since inception. During the six months ended June 30, 2023, net loss was $33,939, cash used in operations was $22,591 and the Company received net proceeds of $7,866 from sales of shares of its Class A common stock under the Equity Distribution Agreement. The Company held cash and cash equivalents of $43,144, excluding restricted cash of $483, and investment in short-term marketable securities of $21,083 as of June 30, 2023. The Company believes that it will have sufficient working capital to operate for a period of at least one year from the issuance of the June 30, 2023 condensed consolidated financial statements based on the Company's current cash and cash equivalents balance, which includes the borrowings under the Blue Torch Financing Agreement (as defined in Note 6).

The Company’s assessment of the period of time through which its financial resources will be adequate to support its operations is a forward-looking statement and involves risks and uncertainties. The Company’s actual results could vary as a result of many factors, including its growth rate, subscription renewal activity, the timing and extent of spending to support its infrastructure and research and development efforts and the expansion of sales and marketing activities. The Company may in the future enter into arrangements to acquire or invest in complementary businesses, services, and technologies, including intellectual property rights. The Company has based its estimates on assumptions that may prove to be wrong, and it could use its available capital resources sooner than it currently expects. The Company may be required to seek additional equity or debt financing. Future liquidity and cash requirements will depend on numerous factors, including market penetration, the introduction of new products, and potential acquisitions of related businesses or technology. In the event that additional financing is required from outside sources, the Company may not be able to raise it on acceptable terms or at all. If the Company is unable to raise additional capital when desired, or if it cannot expand its operations or otherwise capitalize on its business opportunities because it lacks sufficient capital, its business, results of operations, and financial condition would be adversely affected.

Macroeconomic and Geopolitical Impact

Over the past two years, the Company has been impacted by the macroeconomic environment, such as fluctuations in foreign currencies, the COVID-19 pandemic, increasing interest rates and the Russian invasion of Ukraine.

A stronger U.S. dollar relative to the Company's foreign subsidiaries' local functional currencies for the six months ended June 30, 2023 as compared to the six months ended June 30, 2022 impacted the Company’s revenue, since approximately one-third of the Company’s sales are transacted in foreign currencies, though it positively impacted the Company’s expenses, since a majority of the Company’s employees reside in countries outside of the United States.

The macroeconomic environment has caused existing or potential customers to re-evaluate their decision to purchase the Company's offerings, at times resulting in additional customer discounts, extended payment terms, longer sales cycles, and a few contract cancellations.

Increasing interest rates in the six months ended June 30, 2023 as compared to the six months ended June 30, 2022 resulted in higher interest expenses, as the Company’s credit facility is based on a floating interest rate. The Russian invasion of Ukraine and the continued conflict created additional global sanctions, which at times caused scheduling shifts or launch cancellations by third-party satellite launch providers, which has delayed revenue recognition of certain sales contracts.

If any of these factors continue or worsen, and/or if new macroeconomic or geopolitical issues arise, the Company's results and financial condition could be further negatively impacted. The Company cannot predict the timing, strength, or duration of any economic slowdown, downturn, instability, or recovery, generally or within any particular industry or geography. Any downturn of the general economy or industries in which the Company operates would adversely affect its business, financial condition, and results of operations.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the dates of the condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Management’s significant estimates include assumptions in revenue recognition, allowance for credit losses, valuation of certain assets and liabilities acquired from the acquisition of exactEarth in November 2021 (the “Acquisition”), realizability of deferred income tax assets, and fair value of equity awards, contingent earnout liabilities and warrant liabilities. Actual results could differ from those estimates.

Based on an evaluation of the lifespans of its in-service satellites and on current capabilities to extend the useful life of in-service satellites via software updates, the Company changed the estimated useful life of its capitalized satellites and related launch costs from three to four years for depreciation purposes. The Company determined it was appropriate to make this change prospectively beginning June, 2023. The change in estimated useful life did not have a material impact for the three and six month periods ended June 30, 2023, respectively.

Cash, Cash Equivalents, Marketable Securities and Restricted Cash

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Restricted cash included in Other long-term assets, including restricted cash on the condensed consolidated balance sheets represents amounts pledged as guarantees or collateral for financing arrangements and lease agreements, as contractually required.

The Company invests in highly rated securities, with the primary objective of minimizing the potential risk of principal loss. The Company’s investment policy generally requires securities to be investment grade and limits the amount of credit exposure to any one issuer. The Company’s investments in marketable debt securities have been classified and accounted for as available-for-sale. The Company classifies its marketable debt securities as either short-term or long-term based on each instrument’s underlying contractual maturity date. Unrealized gains and losses on marketable debt securities classified as available-for-sale are recognized in Accumulated other comprehensive loss. Interest on securities classified as available-for-sale is included in Interest income on the condensed consolidated statements of operations.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents and restricted cash, marketable securities, and accounts receivable. The Company typically has cash accounts in excess of Federal Deposit Insurance Corporation insurance coverage. The Company has not experienced any losses on such accounts, and management believes that the Company’s risk of loss is remote.

The Company has a concentration of contractual revenue arrangements with various government agencies. Entities under common control are reported as a single customer. As of June 30, 2023, the Company had one customer (Customer B noted below) that accounted for 47% of the Company’s total accounts receivable. As of December 31, 2022, the Company had one customer (Customer A noted below) that accounted for 16% of the Company’s total accounts receivable.

Related Parties

In conjunction with the Company's acquisition of exactEarth in November 2021, Myriota Pty Ltd ("Myriota"), an existing Spire customer, became a related party as a result of exactEarth's 14% ownership of Myriota. As of June 30, 2023, $2,815 of investment in Myriota is included in Other long-term assets, including restricted cash on the condensed consolidated balance sheets. The Company accounts for this investment using the equity method of accounting. The Company's share of earnings or losses on the investment is recorded on a one month lag, due to the timing of receiving financial statements from Myriota, as a component of Other expense, net in the condensed consolidated statements of operations. The Company generated $231 and $434 in revenue for the three and six months ended June 30, 2023, respectively, and had no outstanding accounts receivable from Myriota as of June 30, 2023. For the three and six months ended June 30, 2022, the Company generated $521 and $1,047 in revenue, respectively, and had $170 of accounts receivable from Myriota as of December 31, 2022.

Accounting Pronouncements Recently Adopted

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. The guidance is effective for annual reporting periods beginning after December 15, 2022, including interim periods within that reporting period

and should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The adoption of ASU 2021-08 as of January 1, 2023 did not impact the Company's condensed consolidated financial statements.

In September 2022, the FASB issued ASU 2022-04, Liabilities - Supplier Finance Programs (Subtopic 405-50), guidance on modifying the disclosure requirements to enhance the transparency of supplier finance programs including disclosure of the key terms of the program, the amount outstanding that remains unpaid by the buyer as of the end of the annual period, a description of where those obligations are presented in the balance sheets, and a roll forward of those obligations during the annual period. The amendments in this update are effective for financial statements issued for annual periods beginning after December 15, 2022. The adoption of ASU 2022-04 as of January 1, 2023 did not impact the Company's condensed consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

In March 2023, the FASB issued ASU 2023-01, Leases – Common Control Arrangements (Topic 842), to improve the accounting for amortizing leasehold improvements associated with arrangements between entities under common control. The amendment requires that leasehold improvements be amortized by the lessee over the useful life of the leasehold improvements to the common control group (regardless of the lease term) as long as the lessee controls the use of the underlying asset through a lease. Additionally, leasehold improvements should be accounted for as a transfer between entities under common control through an adjustment to equity when the lessee no longer controls the use of the underlying asset. The amendments in this update are effective for financial statements issued for annual periods beginning after December 15, 2023, with early adoption permitted. The Company does not expect this ASU to have a material impact on its consolidated financial statements.
