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 six months ended June 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, prepaid expenses that were previously included in “prepaid and other current assets” have been reclassified and are now presented as separate line items in the condensed consolidated balance sheet as of December 31, 2024 and the condensed consolidated statement of cash flows for the six months ended June 30, 2024.
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 expects to maintain its EGC status through the last day of the fiscal year following November 2026, the fifth anniversary of its IPO, and 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, valuation of the Company’s ESPP expense, 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 $2.4 million for both the three and six months ended June 30, 2025, resulting in increases of $0.04 per basic and diluted share for both the three and six months ended June 30, 2025. The Company expects an additional reduction in depreciation expense and increase in net income of approximately $2.8 million for the remainder of 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.
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 six months ended June 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 Company is currently assessing the implications of these tax law changes and does not expect that they will have a material impact on its condensed consolidated financial statements. Since the OBBB Act was enacted after the Company’s balance sheet date, the Company’s income tax provision and related income tax accounts for the three and six months ended June 30, 2025, does not incorporate the effects of these tax law changes.
Concentrations and Risks and Uncertainties

Credit risk. Financial instruments that potentially subject the Company to credit risk primarily consist of cash, cash equivalents, accounts receivable, marketable securities, and unbilled accounts receivable. The Company maintains its cash, restricted cash, and marketable securities with high-quality financial institutions with investment-grade ratings. In the event of a failure of any financial institutions where the Company maintains deposits, it may lose timely access to its funds at such institutions and incur significant losses to the extent its funds exceed the $250,000 limit insured by the Federal Deposit Insurance Corporation. Deposits with these financial institutions may exceed the amount of insurance provided on such deposits. For accounts receivable, the Company is exposed to credit risk in the event of nonpayment by customers to the extent of the amount recorded on the condensed consolidated balance sheets. The Company does not have separate collateral requirements to support financial instruments subject to credit risk.

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 business.
The following table presents concentrations related to the Company’s cash disbursements, accounts payable transactions, and accounts receivable transactions:

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.
Recently Issued Accounting Pronouncements

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. This ASU is effective for annual reporting periods 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. As a result, the Company will implement the standard beginning with its annual reporting period ending December 31, 2025. 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.

The Company classifies its U.S. treasury securities and money market funds within Level 1 of the fair value hierarchy, as their fair value is determined by quoted prices in active markets for identical assets. The Company classifies its corporate debt securities within Level 2 of the fair value hierarchy as the fair value of these securities is determined using inputs other than quoted prices that are directly or indirectly observable in the market, including readily available pricing sources for underlying securities that may not be actively traded.
The following table presents the level within the fair value hierarchy at which the Company’s held-to-maturity investments are measured (in thousands):

Leases [Abstract]  
Leases Leases
The Company enters into finance lease arrangements to obtain hard drives and related equipment for its data center operations. The terms of these agreements generally range from two to four years and certain of these arrangements have optional renewals to extend the term of the lease generally at a fixed price. Contingent rental payments are generally not included in the Company’s finance lease agreements. Finance leases are generally secured by the underlying leased equipment. The Company's finance leases have original lease periods expiring between 2025 and 2029. Financing lease right-of-use assets are included in property and equipment, net on the Company’s condensed consolidated balance sheets.

The Company leases its facilities for data center spaces and office space under non-cancelable operating leases with various expiration dates. Certain lease agreements include renewal options to extend the lease term at a price to be determined upon exercise. These options are not reasonably certain to be exercised and therefore are not factored in the determination of lease payments. Contingent rental payments are generally not included in the Company’s lease agreements. The Company’s lease agreements do not contain any material residual value guarantees or restrictive covenants. The Company's leases have original lease periods expiring between 2025 and 2033. The Company had no short-term leases as of June 30, 2025.
The weighted average remaining lease terms and discount rates as of June 30, 2025 and December 31, 2024 were as follows:

In June 2025, the Company amended an existing lease for a data center facility to (i) extend the non-cancellable term of the original lease and (ii) expand into additional infrastructure designed to support multiple-storage offerings. This expansion is expected to commence in the second quarter of 2026 and includes a non-cancellable lease term of approximately seven years. The original lease term was also extended to align with this period.
The multi-storage data center space is considered a separate asset class from the original co-location infrastructure due to its differentiated architectural characteristics, service delivery model, and operational risk profile. The lease and non-lease components of this new asset class are combined in accordance with the Company’s established lease accounting policy. The Company’s current asset classes of operating lease agreements include rentals of (i) office space, (ii) multi-storage data center spaces, and (iii) co-location data center spaces. The Company refers to multi-storage data center spaces and co-location data center spaces collectively as “data center spaces”.
The Company accounted for the lease amendment as a modification under ASC 842. The amendment consists of two components: (i) an extension of the original lease term, which was remeasured as of the modification date, and (ii) a lease for additional, distinct space, which will be accounted for as a separate lease component and measured at its commencement date in the second quarter of 2026. The Company applied an incremental borrowing rate (“IBR”) of 6.8% to remeasure the lease liability. The IBR was estimated based on current market rates for secured borrowings with similar terms and adjusted for the Company’s credit profile. The lease amendment increased total undiscounted minimum lease payments by approximately $34.5 million, of which $17.5 million relates to the expanded space.

Commitments and Contingencies Commitments and Contingencies
Contractual Commitments
The Company has non-cancellable commitments related mainly to service agreements used to facilitate the Company’s operations. As of June 30, 2025, the Company had $1.2 million, $2.7 million, $1.9 million, and $0.7 million payable for these commitments during the remainder of the year ending December 31, 2025 and the years ending December 31, 2026, 2027, and 2028 respectively.

During the six months ended June 30, 2024, the Company made payments of $0.2 million to a related party, Meaningful Works, for marketing services per terms of an agreement. An executive officer of Meaningful Works is an immediate family member of the Company’s CEO. As of December 31, 2024, the scope of services has been completed per terms of the agreement.
401(k) Plan
The Company sponsors a 401(k) defined contribution plan covering all eligible U.S. employees. Contributions to the 401(k) plan are discretionary. The Company contributed $0.5 million to the 401(k) plan for both the three months ended June 30, 2025 and 2024 and $1.0 million for both the six months ended June 30, 2025 and 2024, respectively.
Legal Matters
The Company is involved from time to time in various claims and legal actions arising in the ordinary course of business. Where appropriate, the Company has established accruals for matters that are both probable and reasonably estimable. We also generally maintain insurance to cover certain types of litigation claims, subject to policy limits, retentions and deductibles, and other factors. Based on information currently available, management does not expect the resolution of these matters, individually or in the aggregate, to have a material adverse effect on the Company’s financial position, results of operations, or cash flows. Nonetheless, the outcome of litigation is inherently uncertain, and unforeseen developments could result in an adverse impact on the Company, including defense and settlement costs, diversion of management resources, and other factors.
Indemnification
The Company enters into indemnification provisions under agreements with other parties from time to time in the ordinary course of business. These agreements may require the Company to indemnify and defend the indemnified party against third-party claims arising from the Company’s activities or from any breaches of representations or warranties made by the Company. It is not possible to reasonably estimate the maximum potential amount under these indemnification agreements due to the unique facts and circumstances of each arrangement. To date, the Company has not incurred any material costs or losses in connection with such indemnification obligations. As a result, the Company has not recorded any liabilities related to these obligations in its condensed consolidated financial statements as of the periods presented.

Debt Debt
Revolving Credit Facility
On June 4, 2025, the Company entered into a credit agreement (the “Credit Agreement”) with Citizens Bank, N.A. (the “Lender”), establishing a senior secured revolving credit facility with a total capacity of $20.0 million (the “Revolving Credit Facility”) to be used for general corporate purposes and working capital needs. The Revolving Credit Facility includes a sub-limit of up to $3.0 million for the issuance of letters of credit. The Credit Agreement is scheduled to mature on June 4, 2027, at which point all obligations become due. The Credit Agreement includes an option that allows the
Company to extend the maturity date by one year, subject to certain conditions. We incurred $0.6 million of deferred financing costs in connection with the establishment of the Revolving Credit Facility, which is included in other assets and will be amortized on a straight-line basis over the two-year term of the facility.
The Revolving Credit Facility is secured by a first-priority lien on substantially all assets of the Company and its consolidated subsidiaries, each of which also guarantees the obligations under the facility. Borrowings under the facility bear interest at a variable rate, at the Company’s discretion, equal to either (a) the average Secured Overnight Financing Rate plus 3.25% or (b) a base rate, as defined in the Credit Agreement, plus 2.25%. Additionally, the Credit Agreement requires the payment of a commitment fee of 0.35% on the unused portion of the Revolving Credit Facility and a letter of credit availability fee of 0.125% on outstanding letters of credit.

As of June 30, 2025, the Company had no outstanding borrowings under the Revolving Credit Facility nor outstanding letters of credit. As of June 30, 2025, $20.0 million was available for borrowing under the Revolving Credit Facility.
Debt Covenants under the Credit Agreement
The Credit Agreement contains customary restrictive financial and operating covenants, including limitations on our ability to incur additional indebtedness, pay dividends, make certain investments, sell assets, and engage in other specified transactions. In August 2025, in connection with the establishment of a new share repurchase program (see Note 16 for further information), the Company amended the Credit Agreement to permit share repurchases of up to $10.0 million, thereby excluding such repurchases from the covenant restrictions. The Credit Agreement also requires the Company to comply with the following financial covenants on a quarterly basis: (i) a minimum liquidity of $10.0 million held on deposit with the Lender, over which the Company retains control and considers as cash and cash equivalents, (ii) a minimum consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) threshold, and (iii) a maximum total leverage ratio of 2.75 to 1.00, which is calculated based on consolidated EBITDA.
The Credit Agreement defines consolidated EBITDA on a trailing four fiscal quarter basis and includes specified adjustments and exclusions. As a result, EBITDA as defined under the Credit Agreement may differ materially from Adjusted EBITDA as presented elsewhere in this report. For example, the calculation of EBITDA under the Credit Agreement includes exceptions and caps related to adjustments for (i) restructuring and other strategic initiatives, (ii) legal settlements, (iii) completed acquisitions, and (iv) all other non-specified non-recurring charges. As of June 30, 2025, the Company was in compliance with the covenants under the Credit Agreement. Failure to comply with these covenants could have a material adverse effect on the Company’s financial condition and liquidity.

RCA Debt Facility
On December 10, 2024, the Company voluntarily terminated its revolving credit agreement (as amended, the “RCA”) with City National Bank.

As of June 30, 2024, the interest rate associated with the outstanding balance under the RCA was 8.1% per annum. Total interest expense and amortization of debt issuance costs related to the RCA was $0.1 million and $0.2 million for the three and six months ended June 30, 2024, respectively.

In 2021, the Company adopted the 2021 Equity Incentive Plan (the “2021 Plan”) under which the Company may grant options, stock appreciation rights, restricted stock units (“RSUs”), restricted stock awards, other equity-based awards and incentive bonuses to employees, officers, non-employee directors and other service providers of the Company and its affiliates.

The number of shares available for issuance under the 2021 Plan is increased on January 1 of each year beginning in 2022 and ending with a final increase in 2031 in an amount equal to the lesser of: (i) 4,784,100 shares, (ii) 5% of the total number of shares of Class A common stock outstanding on the preceding December 31, or (iii) a smaller number of shares determined by the Company’s Board of Directors.

In 2021, the Company adopted the 2021 Employee Stock Purchase Plan (the “2021 ESPP”). The number of shares available for issuance under the 2021 ESPP is increased on January 1 of each year beginning in 2022 and ending with a final increase in 2041 in an amount equal to the lesser of: (i) 1,913,630 shares, (ii) 2% of the total number of shares of Class A common stock outstanding on the preceding December 31, or (iii) a smaller number of shares determined by the Company’s Board of Directors.

On August 2, 2024, the Company adopted the 2024 New Employee Equity Incentive Plan (the “Inducement Plan”), pursuant to which the Company reserved 414,740 shares of its Class A common stock to be used exclusively for grants of equity-based awards to individuals who were not previously employees or directors of the Company.

Restricted Stock Units
RSUs granted under the 2021 Plan generally vest based on continued service up to a four-year period for employees and over a one-year period for non-employee directors.

The 2025 Bonus Plan is contingent upon the achievement of annual corporate performance targets. In each respective calendar year, the Company accrues for the 2025 Bonus Plan. The Compensation Committee assesses the actual performance against these targets to determine the payout amount which is disbursed in the following year. Payouts include both cash and RSU components, which are accounted for under Accounting Standards Codification (“ASC”) 710, Compensation-General and ASC 718, Compensation-Stock Compensation, respectively. The RSUs will be issued under the 2021 Plan and are subject to performance and service condition vesting requirements, beginning from the grant date to the payout date, with the number of RSUs calculated in accordance with the established payout amount. Participants must remain employed with the Company through the date of payout to maintain eligibility under the 2025 Bonus Plan.
During March 2022, the Compensation Committee approved the Bonus Plan (as defined in Note 14 to Notes to Consolidated Financial Statements in the Annual Report) for its employees. In January 2025, the Compensation Committee approved the issuance of 301,571 RSUs that vested based on actual performance against the targets set in the Bonus Plan for the year ended December 31, 2024.
Pursuant to the bonus plans, the Company recognized $1.0 million and $0.5 million in stock-based compensation during the three months ended June 30, 2025 and 2024, respectively, of which the Company capitalized $0.1 million in each period for the development of internal-use software. The Company recognized $2.1 million and $1.3 million in stock-based compensation during the six months ended June 30, 2025 and 2024, respectively, of which the Company capitalized $0.2 million in each period for the development of internal-use software.

Earnings Per Share [Abstract]  
Net Loss per Share Attributable to Common Stockholders Net Loss per Share Attributable to Common Stockholders
Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potentially dilutive common stock equivalents during the period. For purposes of this calculation, the Company’s stock options, share purchase rights pursuant to the Company’s ESPP, and unvested restricted stock are considered to be potential common stock equivalents, but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is antidilutive.

The following table presents the calculation of basic and diluted net loss per share (in thousands, except share and per share data):

Since the Company was in a loss position for all periods presented, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been antidilutive. The weighted average potential shares of common stock that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented are as follows:

In November 2024, management approved a restructuring plan intended to improve the Company’s cost structure and operating efficiency (the “2024 Restructuring Plan”). The 2024 Restructuring Plan included an involuntary reduction in headcount of approximately 12% of the Company’s workforce. In addition, as part of the 2024 Restructuring Plan, the Company reduced its footprint at its corporate headquarters. The 2024 Restructuring Plan was substantially completed as of December 31, 2024.

The 2024 Restructuring Plan resulted in total restructuring charges of $4.9 million, which were recognized in the fourth quarter of 2024, primarily consisting of employee severance and benefits of $3.9 million, impairment charges of
$0.9 million on its operating right-of-use assets related to the lease of the Company’s corporate headquarters, and professional fees of $0.1 million. In the second quarter of 2025, the Company recorded a $0.1 million credit to the estimated severance and benefits costs and an incremental impairment charge of $0.1 million related to the execution of the sublease of the Company’s corporate headquarters.

Segment Reporting [Abstract]  
Segment Reporting Segment Reporting
The Company operates in one operating and reportable segment, which derives revenue from the services operating on its storage platform. The Company’s chief operating decision maker (the “CODM”) is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance and allocating resources.

Measure of Segment Profit or Loss

The key measure of segment profit or loss utilized by the CODM to assess the performance of and allocate resources to the Company’s operating segment is consolidated net income (loss). Net income (loss) is used in monitoring budget versus actual results and is presented on the condensed consolidated statements of operations and comprehensive loss. The measure of segment assets is reported on the condensed consolidated balance sheet as total consolidated assets.

The CODM reviews cost of revenue, research and development, sales and marketing, and general and administrative expenses exclusive of depreciation, amortization, and stock-based compensation, which are reviewed separately. The segment information for the three and six months ended June 30, 2025 and 2024 is presented below in the following table (in thousands):

Subsequent Events Subsequent Events
In August 2025, the Company announced a share repurchase program to purchase up to $10.0 million of shares of its common stock through August 1, 2026, as approved by the Company’s board of directors. The program is intended to reduce the dilutive impact of stock-based compensation and will be funded through the cash proceeds from stock options exercised by employees and employee purchases under the 2021 ESPP, which is intended to be cash neutral to the Company.

Repurchases may be made from time to time in open market transactions, privately negotiated transactions, or by other means, including automatic purchase plans pursuant to Rule 10b5-1, in accordance with applicable securities laws. The timing, number of shares repurchased, and prices paid for the shares under this program will be generally determined by management based on its evaluation of general business and market conditions as well as corporate and regulatory limitations, prevailing stock prices, and other considerations.

The share repurchase program may be suspended, modified, or discontinued at any time and does not obligate the Company to acquire any amount of common stock.

Accounting Policies [Abstract]  
Basis of Presentation and Principles of Consolidation
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 six months ended June 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
Reclassifications
To conform to the current period’s presentation, prepaid expenses that were previously included in “prepaid and other current assets” have been reclassified and are now presented as separate line items in the condensed consolidated balance sheet as of December 31, 2024 and the condensed consolidated statement of cash flows for the six months ended June 30, 2024.
Use of Estimates
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, valuation of the Company’s ESPP expense, 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 $2.4 million for both the three and six months ended June 30, 2025, resulting in increases of $0.04 per basic and diluted share for both the three and six months ended June 30, 2025. The Company expects an additional reduction in depreciation expense and increase in net income of approximately $2.8 million for the remainder of 2025.
Comprehensive Loss
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.
Income Taxes
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 six months ended June 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 Company is currently assessing the implications of these tax law changes and does not expect that they will have a material impact on its condensed consolidated financial statements. Since the OBBB Act was enacted after the Company’s balance sheet date, the Company’s income tax provision and related income tax accounts for the three and six months ended June 30, 2025, does not incorporate the effects of these tax law changes.
Concentrations and Risks and Uncertainties
Concentrations and Risks and Uncertainties

Credit risk. Financial instruments that potentially subject the Company to credit risk primarily consist of cash, cash equivalents, accounts receivable, marketable securities, and unbilled accounts receivable. The Company maintains its cash, restricted cash, and marketable securities with high-quality financial institutions with investment-grade ratings. In the event of a failure of any financial institutions where the Company maintains deposits, it may lose timely access to its funds at such institutions and incur significant losses to the extent its funds exceed the $250,000 limit insured by the Federal Deposit Insurance Corporation. Deposits with these financial institutions may exceed the amount of insurance provided on such deposits. For accounts receivable, the Company is exposed to credit risk in the event of nonpayment by customers to the extent of the amount recorded on the condensed consolidated balance sheets. The Company does not have separate collateral requirements to support financial instruments subject to credit risk.

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 business.
The following table presents concentrations related to the Company’s cash disbursements, accounts payable transactions, and accounts receivable transactions:

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.
Recently Issued Accounting Pronouncements
Recently Issued Accounting Pronouncements

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. This ASU is effective for annual reporting periods 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. As a result, the Company will implement the standard beginning with its annual reporting period ending December 31, 2025. 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.
