Accounting Policies [Abstract] |
Basis of Presentation and Summary of Significant Accounting Policies | Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, they do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes for the year ended December 31, 2024 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the SEC on March 11, 2025 (the “Annual Report”). In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and reflect all adjustments, which include normal recurring adjustments necessary for fair presentation. The results of operations for the three and nine months ended September 30, 2025 and 2024 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period. Reclassifications To conform to the current period’s presentation, certain prior-period amounts have been reclassified as follows: •Prepaid expenses that were previously included in “Prepaid and other current assets” are now presented as a separate line item in the condensed consolidated balance sheet as of December 31, 2024, and in the condensed consolidated statement of cash flows for the nine months ended September 30, 2024. •Accounts payable has been combined with ‘”Accrued expenses and other current liabilities” in the condensed consolidated balance sheet as of December 31, 2024 and in the condensed consolidated statement of cash flows for the nine months ended September 30, 2024. •Net accretion of discount on investment securities and net realized investment gains has been combined with “Other” in the condensed consolidated statement of cash flows for the nine months ended September 30, 2024. These reclassifications had no impact on total assets, liabilities, or stockholders’ equity. Emerging Growth Company The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, EGCs can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. The Company will maintain its EGC status until December 31, 2026, which is the last day of the fiscal year following either of the following triggering events: (i) if the Company’s public float exceeds $700 million as of June 30, 2026, or (ii) the fifth anniversary of the Company’s initial public offering in November 2026. The Company intends to use the extended transition period for any other new or revised accounting standards during the period in which it remains an EGC. Significant accounting policies The Company’s significant accounting policies are disclosed in the Company’s audited consolidated financial statements and related notes thereto included in the Annual Report. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and the accompanying notes. Such estimates and assumptions include the costs to be capitalized as internal-use software, which include determining whether projects will result in new or additional functionality, the useful lives of other long-lived assets, impairment considerations for long-lived assets, the incremental borrowing rate for lease agreements, lease and non-lease component allocation, estimates related to variable consideration, the expected period of benefit of deferred contract acquisition costs, and accounting for income taxes, including estimates for deferred tax assets, valuation allowance, and uncertain tax positions. The Company bases its estimates on historical experience and on assumptions that management considers reasonable. Future actual results could differ materially from these estimates. During the second quarter of 2025, the Company completed a study of the useful lives of its property and equipment. Effective April 1, 2025, the estimated lives of (i) data center equipment, which includes hard drives, and (ii) machinery and equipment, which includes servers and other infrastructure equipment, were extended on a prospective basis from a range of 3 to 5 years to a uniform 6 years. The reassessment was based on historical data and continuous improvements made to the efficiency and durability of the Company’s storage infrastructure. The change in estimate reduced depreciation expense and increased net income by approximately $1.7 million and $4.1 million for the three and nine months ended September 30, 2025, respectively, resulting in increases of $0.03 and $0.07 per basic and diluted share for the three and nine months ended September 30, 2025, respectively. The Company expects an additional reduction in depreciation expense and increase in net income of approximately $1.1 million for the remainder of the year ending December 31, 2025. Comprehensive Loss The Company does not have any components of other comprehensive income recorded within the condensed consolidated financial statements and therefore does not separately present a statement of comprehensive income in the condensed consolidated financial statements. Foreign Currency The reporting currency and functional currency of the Company and its wholly owned foreign subsidiaries is the U.S. dollar (“USD”). Transactions denominated in currencies other than USD are remeasured into USD at exchange rates in effect on the transaction date. Monetary assets and liabilities denominated in foreign currencies are subsequently remeasured at exchange rates in effect at the balance sheet date, with resulting transaction gains and losses recognized in loss from operations in the condensed consolidated statements of operations and comprehensive loss. Foreign exchange (gain) loss included in the condensed consolidated statements of operations was as follows (in thousands):
| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2025 |  | 2024 |  | 2025 |  | 2024
Foreign exchange (gain) loss | $ | (189) |  |  | $ | 178 |  |  | $ | 437 |  |  | $ | 159 |
Income Taxes The Company is subject to U.S. federal and state income taxes as a corporation. The Company’s tax provision and the resulting effective tax rate for interim periods is determined based upon its estimated annual effective tax rate adjusted for the effect of discrete items arising in that quarter. The effective tax rate for each of the three and nine months ended September 30, 2025 and 2024 was zero as the Company has incurred continuous operating losses. On July 4, 2025, the One Big Beautiful Bill Act (the “OBBB Act”) was enacted, introducing amendments to U.S. tax laws with various effective dates from 2025 to 2027. The OBBB Act includes significant provisions, such as the permanent extension of certain expiring provisions of the 2017 Tax Cuts and Jobs Act, international tax framework, and the restoration of favorable tax treatment for certain business provisions including the immediate expensing of the US research and development expenditure. The Company continues to assess the implications of these tax law changes; however, based on a preliminary assessment, the OBBB Act did not have a material impact on the Company’s condensed consolidated financial statements for the three and nine months ended September 30, 2025 and the Company does not expect that the OBBB Act will have material impact on the Company’s consolidated financial statements for the fiscal year 2025. Concentrations and Risks and Uncertainties Credit risk. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, marketable securities, accounts receivable, and unbilled receivables. The Company maintains its cash, cash equivalents, and marketable securities with high-quality financial institutions that have investment-grade credit ratings. Although these institutions are considered to be financially sound, deposits may exceed the amounts insured or guaranteed by the Federal Deposit Insurance Corporation, which could subject the Company to risk of loss in the event of the failure of any such financial institution. The Company is also exposed to credit risk related to accounts receivable and unbilled receivables from customers. The Company does not have separate collateral requirements to support financial instruments subject to credit risk. Concentration of vendors. The Company acquires infrastructure equipment from third-party vendors. Vendors may have limited sources of equipment and supplies, which may expose the Company to potential supply-chain and service disruptions that could harm the Company’s busine ss. The following table presents concentrations related to the Company’s cash disbursements, accounts payable transactions, and accounts receivable transactions:
| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2025 |  | 2024 |  | 2025 |  | 2024
Cash disbursement concentration |  |  |  |  |  |  |
Number of vendors | 2 |  | 3 |  | 2 |  | 3
Total cash disbursements represented by vendors listed above | 23% |  | 40% |  | 26% |  | 37%
|  |  |  |  | September 30, 2025 |  | December 31, 2024
Accounts payable concentration |  |  |  |  |  |  |
Number of vendors |  |  |  |  | 3 |  | 1
Total accounts payable balance represented by vendors listed above |  |  |  |  | 49% |  | 14%
Accounts receivable concentration |  |  |  |  |  |  |
Number of customers |  |  |  |  | 3 |  | 2
Total accounts receivable balance represented by customers listed above |  |  |  |  | 42% |  | 35%
Revenue. The Company derives substantially all of its revenue from the services operating on its Backblaze Storage Cloud platform: its Backblaze B2 Cloud Storage (“B2 Cloud Storage”) and Backblaze Computer Backup (“Computer Backup”) offerings. The potential for severe impact on the Company’s business could result if the Company was unable to operate its platform or serve customers through its platform for an extended period of time. Regulatory Developments In January 2024, the European Union (“EU”) enacted the EU Data Act, which became effective in September 2025. The legislation establishes statutory rights for EU and European Economic Area (“EEA”) customers, including the ability to terminate contracts with no more than two months’ notice, reimbursement of unused prepaid service, and limitations on early termination penalties, among other changes. These provisions primarily affect the Company’s subscription arrangements with EU and EEA customers by shortening the enforceable contract term and requiring consideration of expanded refund rights. The Company evaluated the implications of the EU Data Act on its customer arrangements, including remaining performance obligations, and determined that it did not have a material impact on the Company’s consolidated financial statements for the current reporting period. The Company has incorporated the provisions of the EU Data Act into its revenue recognition policies and contract assessments and expects to reflect any impact prospectively as customer arrangements are modified or renewed under the new requirements. Recently Issued Accounting Pronouncements In September 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2025-06, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software.” This standard updates the recognition model for internal-use software by eliminating the project stage framework and requiring capitalization once projects are approved and completion is probable, and also clarifies related disclosure requirements. This ASU is effective for all entities fiscal years beginning after December 15, 2027, including interim periods within those years, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this standard. In July 2025, the FASB issued ASU 2025-05, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets.” This standard allows entities to apply a practical expedient when estimating expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers. The standard is effective for all entities for fiscal years beginning after December 15, 2025, including interim periods within those fiscal years. Early adoption is permitted, and the standard is to be applied prospectively. The Company is currently evaluating the impact of the adoption of this standard. In November 2024, the FASB issued ASU 2024-03, “Income Statement (Subtopic 220-40) - Reporting Comprehensive Income - Expense Disaggregation Disclosures.” The ASU requires disclosure of specified information about certain costs and expenses, including (i) certain amounts already required to be disclosed in the same disclosure as the other disaggregation requirements, (ii) a qualitative description of amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, and (iii) the total amount of selling expenses and an entity’s definition of such expenses. For public companies, this ASU is effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027 on either a prospective or retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of this standard. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740) - Improvements to Income Tax Disclosures” requiring enhancements and further transparency to certain income tax disclosures, most notably the tax rate reconciliation and income taxes paid. This ASU is effective for fiscal years beginning after December 15, 2024 for public companies and is effective for fiscal years beginning after December 15, 2025 for non-public business entities. In accordance with our EGC status, the Company will implement the standard beginning with its annual reporting period ending December 31, 2026. This amendment should be applied on a prospective basis and retrospective application is permitted. The Company is currently evaluating the impact of the adoption of this standard.
