These launches expand our addressable market among enterprise and AI-driven customers and lay the groundwork for further innovation to drive differentiated value for these customers.

Financial Developments

Follow-On Public Offering

On November 20, 2024, we issued and sold an aggregate of 6,250,000 shares (the “Shares”) of our Class A common stock, par value $0.0001 per share (the “Common Stock”) at a public offering price of $5.60 per share (the “Follow-On Offering”).

We also granted the underwriters an option to purchase up to an additional 937,500 shares of Common Stock at the same per-share price of $5.60 per share, which they exercised.

We received net proceeds of $37.4 million from the offering, after deducting the underwriting discounts and commissions and other offering expenses.

Banking Relationship and Line of Credit

On December 10, 2024, we voluntarily terminated our Loan and Security Agreement with City National Bank, dated October 21, 2021, as amended, which included a revolving line of credit that was 100% collateralized by cash held by us.

At the time of termination, no amounts were outstanding under the revolving line of credit, as we had fully paid down the revolving credit amount following the completion of our Follow-On Offering in November 2024.

2024 Restructuring Plan

In November 2024, we implemented a restructuring plan intended to improve our cost structure and operating efficiency (the “2024 Restructuring Plan”).

The 2024 Restructuring Plan included a reduction in headcount and in our facilities footprint at our corporate headquarters.

Consolidated Financial Statements — Note 16.

Restructuring — Restructuring Plans” for additional information.

On June 4, 2025, we entered into a credit agreement with Citizens Bank, N.A., establishing a senior secured revolving credit facility with a total borrowing capacity of up to $20.0 million to be used for general corporate purposes and working capital needs.

As of December 31, 2025, the Company had no outstanding borrowings under this facility.

2025 Restructuring and Transformation Plan

In November 2025, we initiated a restructuring and transformation plan designed primarily to improve efficiency and enhance the performance of our sales and marketing functions to support our go-to-market initiatives (the “2025 Restructuring and Transformation Plan”).

The 2025 Restructuring and Transformation Plan includes the reallocation of resources, the redesign of sales and marketing strategies and processes, and other corporate actions.

During the year ended December 31, 2025, we incurred charges of approximately $2.5 million, including employee termination expenses, an impairment charge related to our exit from our corporate headquarters facility, and other transformation costs.

We expect to incur additional charges of approximately $4.7 million to $7.5 million through the first quarter of 2027, at which time the 2025 Restructuring Plan is expected to be completed.

These charges include estimated employee termination expenses of approximately $0.8 million to $1.2 million, and other business transformation costs.

Share Repurchase Program

In August 2025, our Board of Directors approved a share repurchase program authorizing us to repurchase up to $10.0 million of our Class A common stock through August 1, 2026.

The program is intended to offset dilution resulting from stock-based compensation.

Repurchases are to be funded from the proceeds of employee stock option exercises and from employee contributions under the 2021 Employee Stock Purchase Plan.

Our Business Model

Our solutions are designed for individuals and businesses of all sizes, from large-scale enterprise businesses to small and medium-sized businesses (“SMB”) and across all industries.

Our solutions are designed to serve a wide range of customers from individuals and small businesses to large enterprises across all industries.

Our solutions appeal to customers with a desire for easy-to-use and cost-effective solutions while also delivering reliability and performance.

We generate revenue primarily from our two cloud services:

• Backblaze B2 Cloud Storage, which enables customers to store data for a wide range of use cases, and for developers to embed our platform into their applications.

In both cases, our customers use this offering on a consumption-based or capacity-based model or committed contract basis, and

• Backblaze Computer Backup, which provides virtually unlimited backup to businesses and consumers in a SaaS subscription model using primarily flat-rate pricing.

We believe our pricing is simple and straightforward, with fees and terms that are generally shared transparently on our website.

We believe we provide simple pricing for usage of our cloud services and increase revenue per customer through our customers’ natural data growth.

Additionally, we provide customers with additional value through cross-sell, upsell, and

use case expansion that can result in additional revenue per customer.

These options for cross-selling and upselling include the following:

Our business model is supported by a highly efficient cloud storage platform built on proprietary software and commodity hardware, which enables us to deliver predictable pricing and attractive price-to-performance at scale.

Our two primary cloud services are B2 Cloud Storage and Computer Backup, which together enable customers to store, use, and protect their data across a broad variety of use cases.

• B2 Cloud Storage enables customers to store and manage data for use cases ranging from backup and archive to application storage, ransomware protection, and AI/ML workloads.

B2 Cloud Storage operates as an IaaS model, allowing customers to scale usage dynamically on a pay-as-you-go basis or purchase capacity or committed contracts for greater predictability.

In addition to our standard B2 Cloud Storage offering, we provide B2 Overdrive, a premium high-performance storage option designed for data-intensive and AI-driven workloads that

require high sustained throughput and low latency.

Developers and partners can embed our storage into their applications, while enterprise customers use B2 Cloud Storage to support large-scale, data-intensive workflows.

• Computer Backup is designed to provide virtually unlimited backup for businesses and individuals in a SaaS subscription model using primarily flat-rate pricing.

Customers use Computer Backup to automatically and continuously back up data from desktops, laptops, and external drives, with data recoverable at any time through our Backblaze Storage Cloud.

We believe our pricing is simple and transparent, with fees and terms that are generally shared publicly on our website.

Our revenue is primarily recurring and supported by a land-and-expand model that encourages customers to increase usage of our platform over time as their data needs grow.

Additionally, we expand revenue per customer through cross-sell, upsell, and use case expansion opportunities, which include the following:

• Cross-Sell:

After adopting any of our products, customers may expand to other products as their use cases grow, including Computer Backup customers who adopt B2 Cloud Storage to facilitate broader use cases.

Adopting additional products expands usage of our platform.

Customers that adopt one product may expand to another as their use cases evolve, such as Computer Backup customers adding B2 Cloud Storage to enable broader data management.

Customers can choose to use various features and services for additional fees, such as Enterprise Control, Snapshots, cloud replication, and enhanced support tiers.

For example, our Computer Backup cloud service offers Enterprise Control, which provides larger customers with more management for an additional cost.

B2 Cloud Storage offers Snapshots that allow customers to create moment-in-time versions of their data, and we also allow customers to keep their data in multiple geographic regions, both of which provide more customer value.

For example, our Computer Backup cloud service offers Enterprise Control, which provides larger customers with greater administrative management for an additional cost.

B2 Cloud Storage offers Snapshots that allow customers to create moment-in-time versions of their data, and also allows customers to retain data in multiple geographic regions, both of which provide additional flexibility and value.

Additionally, customers receive email and chat support for free, but can also opt for enhanced support tiers for an additional cost, which provide dedicated customer support contacts and 24/7 response.

• Use Case Expansion:

B2 Cloud Storage customers may adopt the service for one business need, but can expand their use cases as their business evolves.

One such example would be a business using B2 Cloud Storage for media asset management storage, which decides to also use the service as an origin store for content distribution;

another would be a business that adopts B2 Cloud Storage for backup and archive purposes, which decides to also enable Object Lock for ransomware protection.

Customers often begin using our products for a single need and expand over time.

For example, a media company using B2 Cloud Storage for asset storage may later use it as an origin store for content distribution.

Another example would be a business that adopts B2 Cloud Storage for backup and archive purposes, which decides to also enable Object Lock for ransomware protection.

Use case expansion enables the opportunity to deepen our relationship with our customers and increase revenue.

We measure this growth by monitoring our overall net revenue retention rate, which measures our ability to retain and expand revenue from existing customers.

We believe that we can drive this metric by continuing to focus on our customers and by adding additional products and functionality to our platform.

Our overall net revenue retention rate is a trailing four-quarter average of the recurring revenue from a cohort of customers in a quarter as compared to the same quarter in the prior year.

We calculate our overall net revenue retention rate for a quarter by dividing (i) recurring revenue in the current quarter from any accounts that were active at the end of the same quarter of the prior year by (ii) recurring revenue in the current corresponding quarter from those same accounts.

Our overall net revenue retention rate includes any expansion of revenue from existing customers and is net of revenue contraction and customer attrition, and excludes revenue from new customers in the current period.

Our net revenue retention rate for B2 Cloud Storage and Computer Backup is calculated in the same manner as our overall net revenue retention rate based on the revenue from our B2 Cloud Storage and Computer Backup solutions, respectively.

Our Net Revenue Retention Rate was essentially flat for B2 Cloud Storage for the year ended December 31, 2024 compared to the year ended December 31, 2023 .

Our Net Revenue Retention Rate increased by 9% for Computer Backup for the year ended December 31, 2024 compared to the year ended December 31, 2023, primarily due to the price increase.

Our continued focus on our customers is driving significant revenue retention, as evidenced by our overall net revenue retention rates (“NRRs”) of 105% and 116% as of December 31, 2025 and December 31, 2024, respectively.

The enhancement of our B2 Cloud Storage offerings is a key contributor to this success, resulting in NRRs of 111% and 123% for the same periods.

The decrease in the NRR for B2 Cloud Storage and Computer Backup was primarily driven by the impact of a price increase, which took place in October 2023, with Computer Backup also reflecting lower expansion from existing customers.

To calculate the NRR for a specific quarter, we determine the revenue recognized in that quarter from customers who generated revenue during the last month of the same quarter of the previous year.

This revenue is then divided by the revenue generated from those same customers in the prior year quarter.

Our overall NRR rate is calculated as the average of these quarterly rates over the past four quarters to provide a comprehensive view of revenue trends.

Gross Customer Retention Rate

1 unchanged sentence

Our gross customer retention rate reflects only customer losses and does not reflect the expansion or contraction of revenue we earn from our existing customers.

We have maintained gross customer retention rates of approximately 90% across our revenue products as of both December 31, 2025 and December 31, 2024.

We believe our high gross customer retention rates demonstrate that we provide a vital service to our customers, as the vast majority of our customers tend to continue to use our platform from one period to the next.

To calculate our gross customer retention rate, we take the trailing four-quarter average of the percentage of cohort of customers who were active at the end of the quarter in the prior year that are still active at the end of the current quarter.

We calculate our gross customer retention rate for a quarter by dividing (i) the number of accounts that generated revenue in the last month of the current quarter that also generated recurring revenue during the last month of the corresponding quarter in the prior year, by (ii) the number of accounts that generated recurring revenue during the last month of the corresponding quarter in the prior year.

Our Gross Customer Retention Rate decreased by 1% for both B2 Cloud Storage and Computer Backup for the year ended December 31, 2024 compared to the year ended December 31, 2023.

To calculate our gross customer retention rate, we take the trailing four-quarter average of our quarterly gross customer retention rates.

We calculate the quarterly gross customer retention rates by dividing (i) the number of accounts that generated revenue in the last month of the current quarter that also generated recurring revenue during the last month of the corresponding quarter in the prior year, by (ii) the number of accounts that generated recurring revenue during the last month of the corresponding quarter in the prior year.

Annual Recurring Revenue

1 unchanged sentence

These expenses include operating in colocation facilities, network and bandwidth costs, and depreciation of our equipment and finance leased equipment in colocation facilities.

These expenses include operating our data center spaces, network and bandwidth costs, and depreciation of our equipment and finance leased equipment in data center spaces.

Personnel-related costs associated with customer support and maintaining service availability, including salaries, benefits, bonuses, and stock-based compensation are also included.

Cost of revenue also includes credit card processing fees, amortization of capitalized internal-use software development costs, and allocated overhead costs.

We intend to continue to invest additional resources in our infrastructure to support the growth of our business.

Some of these investments, including costs of infrastructure equipment (including related depreciation) and expansion, and software development costs and related amortization are incurred in advance of generating revenue, and either the failure to generate anticipated revenue or fluctuations in the timing of revenue could affect our gross margin from period to period.

We plan to continue investing in our infrastructure to support the growth of our business.

These investments include the purchase and expansion of infrastructure equipment (and related depreciation) as well as software development activities and associated amortization.

Because these costs are often incurred ahead of revenue generation, delays in realizing anticipated revenue or fluctuations in the timing of revenue could adversely affect our gross margin from period to period.

During the second quarter of 2025, we completed a study on the useful lives of our property and equipment, resulting in an extension of the useful life of our infrastructure equipment.

This update resulted in a reduction in depreciation expense of approximately $5.2 million for the year ended December 31, 2025 and is anticipated to result in further reduction of approximately $2.8 million for the year ending December 31, 2026.

Operating Expenses

The most significant components of our operating expenses are personnel costs, which consist of salaries, benefits, bonuses, and stock-based compensation.

We also incur other non-personnel costs related to our general overhead expenses.

We expect that our operating expenses will decrease in the near-term as a result of our 2024 Restructuring Plan, however, our operating expenses may increase over time in absolute dollars as we grow our business.

We expect our operating expenses, excluding depreciation, amortization, restructuring charges, and stock-based compensation expenses, to remain relatively flat in 2026 compared to 2025, as efficiencies from our restructuring activities in 2025 offset increased investments in research and development and other growth-related costs.

(1) For the periods presented, Physical Media revenue has been consolidated into B2 Cloud Storage or Computer Backup revenue based on the underlying offering from which it originates.

Revenue increa sed by $25.6 million, or 25%, for the year ended December 31, 2024.

B2 Cloud Storage increased by $16.9 million, or 36% for the year ended December 31, 2024.

The increase was largely due to increased storage from new and existing customers of $8.9 million, the impact of the price increase in October 2023 of $6.0 million, and increased sales of B2 Reserve of $2.0 million .

Computer Backup increased by $8.7 million, or 16% for the year ended December 31, 2024.

The increase was due to the impact of the price increase in October 2023 of $10.6 million and increased storage fees for version history longer than 1 year of $0.7 million.

The increases were partially offset by $2.6 million due to the decreased license count.

Our price increase amounts noted above are inherent estimates that are based on an average price charged per customer and other assumptions that may offset the increase, such as free egress and impact of the price increase on the amount of data stored and customer license count.

Total revenue increased by $18.2 million, or 14%, for the year ended December 31, 2025.

Primary factors influencing the $16.6 million increase in B2 Cloud Storage revenue include the following:

• a $10.1 million increase in sales to new customers;

• a $6.5 million increase driven by higher storage usage as a result of upselling and organic growth by existing customers.

Primary factors influencing the $1.6 million increase in Computer Backup revenue include the following:

• a $4.5 million increase due to price increases that went into effect in October 2023;

• a $0.7 million increase driven by increased utilization by existing customers;

• a $3.6 million decrease from a decline in license counts.

Cost of Revenue

Primary factors influencing the $1.2 million, or 2%, decrease in cost of revenue for the year ended December 31, 2025 include the following:

• a $6.0 million decrease in depreciation expense primarily due to the extension of the useful life of our infrastructure equipment;

• a $1.5 million decrease in personnel-related costs resulting from lower headcount following our recent restructuring and ongoing efficiency initiatives;

• a $3.4 million increase in amortization expense related to capitalized investments in platform enhancements and new software features;

• a $2.9 million increase primarily reflecting incremental rent and facility costs associated with expanding our data center footprint to support increased storage capacity.

Gross margin was 61% for the year ended December 31, 2025 compared to 54% for the year ended December 31, 2024.

The increase in our gross margin was primarily driven by higher revenue and lower fixed costs, including reduced depreciation expense resulting from the extension of the useful life of our infrastructure equipment, effective April 1, 2025, which increased gross margin by approximately 4%.

In addition, improved economies of scale related to personnel supporting cost of sales contributed to the increase.

These benefits were partially offset by higher variable costs associated with the expansion of our data center spaces.

We exclude stock-based compensation, which is a non-cash item, and restructuring charges because we do not consider it indicative of our core operating performance.

We exclude depreciation expense of our property and equipment and amortization expense of capitalized internal-use software because these may not reflect current or future cash spending levels to support our business.

We believe adjusted gross margin provides consistency and comparability with our past

financial performance and facilitates period-to-period comparisons of operations, as this metric eliminates the effects of depreciation and amortization.

Liquidity and Capital Resources

Since inception, we have financed operations primarily through payments received from our customers and, in later periods from the net proceeds from our initial public offering.

As of December 31, 2024 and 2023 , our principal sources of liquidity were cash, restricted cash, and short-term investments of $54.9 million and $33.4 million, respectively.

We believe that our existing cash, cash equivalents, and short-term investments, together with cash provide d by operations, will be sufficient to support our working capital and capital expenditure requirements for at least the next 12 months.

Our material cash requirements include contractual and other obligations under our finance and operating lease agreements, and purchase commitments as discussed below.

Our future capital requirements will depend on many factors, including our total revenue growth rate, the timing and the amount of cash received from customers, the expansion of sales and marketing activities, the timing and extent of spending to support development efforts, the potential expansion of our data centers, the price at which we are able to purchase or lease infrastructure equipment, the impact of inflation on interest rates, the introduction of platform enhancements, and the continuing market adoption of our platform.

Since inception, we have financed operations primarily through payments received from our customers and, in later periods from the net proceeds from our public offerings.

As of December 31, 2025 and 2024 , our principal sources of liquidity were cash, cash equivalents, and marketable securities of $51.4 million and $54.9 million, respectively.

We believe that our existing cash, cash equivalents, and marketable securities, together with cash provided by operations and our revolving credit facility, will be sufficient to support our working capital and capital expenditure requirements for at least the next 12 months.

Our material cash requirements include contractual and other obligations under our credit facility, finance and operating lease agreements, and purchase commitments as discussed below.

Our future capital requirements will depend on many factors, including our total revenue growth rate, the timing and the amount of cash received from customers, the expansion of sales and marketing activities, the timing and extent of spending to support development efforts, the potential expansion of our data center spaces, the price at which we are able to purchase or lease infrastructure equipment, the impact of inflation on interest rates, the introduction of platform enhancements, and the continuing market adoption of our platform.

In the future, we may enter into arrangements to acquire or invest in complementary businesses, products, and technologies.

We plan to continue to enter into finance lease agreements for purchase of infrastructure equipment and may also be required or choose to seek additional equity or debt financing.

To support our up-market transformation, we expect to increase our capital expenditures, continue leveraging finance lease agreements for infrastructure investments and, when strategic opportunities arise, we may supplement our revolving credit facility with additional equity or debt funding to accelerate enterprise-focused growth.

In the event that we require additional financing, we may not be able to raise such financing on terms acceptable to us or at all.

If we are unable to raise additional capital or generate cash flows necessary to expand our operations and invest in continued innovation, we may not be able to compete successfully, which would harm our business, results of operations, and financial condition.

In October 2021, we entered into a revolving credit agreement (as amended to date, the “RCA”) with City National Bank (the “Lender”).

Under the RCA, as amended in December 2023, the maximum borrowing available was reduced from $30 million to $20 million and advances on the line of credit will bear monthly interest at a variable rate equal to, at our discretion, (a) the average SOFR plus 2.75%, or (b) the base rate.

On December 10, 2024, the Company voluntarily terminated its RCA At the time of termination, no amounts were outstanding under the revolving line of credit, as the Company had fully paid down the revolving credit amount following the completion of its Follow-On public offering in November 2024.

The RCA did not have financial covenants and it required us to hold collateral in the form of a lien prior to any advance.

The outsta nding balance was collateralized by an equal amount of cash held, which we were obligated to hold as restricted cash.

For further details, see Note 12 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.

We use City National Bank, a subsidiary of RBC, for our banking needs.

We maintain cash deposits in the United States, in Federal Deposit Insurance Corporation insured banks.

In the event of a failure of any financial institutions where we maintain deposits, we may lose timely access to our funds at such institutions and incur significant losses to the extent our funds exceed the $250,000 limit insured by the Federal Deposit Insurance Corporation.

In addition, the disruption and uncertainty impacting the banking industry from failures of other banks resulted in some reduced access to capital, increased costs of capital, and reduced opportunities to invest with investment grade securities, which may have

also resulted in lower investment yields and investment income.

Any further impact could have a material adverse effect upon our liquidity and business.

We are currently evaluating other options for our banking needs, which may allow greater flexibility and access to additional capital in the future.

We generally enter into finance lease arrangements to obtain hard drives and related equipment for our data center operations.

We also generally enter into leases for our facilities for data centers and office space under non-cancelable operating leases w ith various expiration dates.

Financial Statement and Supplementary Data — Note 10.

Finance Leases and Lease Financing Obligations” for our future minimum commitments related to our finance leases.

On June 4, 2025, we 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 borrowing capacity of up to $20.0 million (the “Revolving Credit Facility”) to be used for general corporate purposes and working capital needs.

The Revolving Credit Facility allows for borrowings, repayments, and re-borrowings up to the total capacity, subject to compliance with the terms of the Credit Agreement.

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 us to extend the maturity date by one year, subject to certain conditions.

Borrowings under the facility bear interest at a variable rate, at our discretion, equal to either (a) the average Secured Overnight Financing Rate (“SOFR”) 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.

Our ability to pay interest on or to refinance our indebtedness depends on our future performance, working capital levels and capital structure, which are subject to general economic, financial, competitive, legislative, regulatory and other factors which may be beyond our control.

There can be no assurance that we will generate sufficient cash flow from our operations or that future financings will be available on acceptable terms or in amounts sufficient to enable us to service or refinance our indebtedness or to make necessary capital expenditures.

As of December 31, 2025, we had no outstanding borrowings under the Revolving Credit Facility.

As of December 31, 2025, no letters of credit were outstanding and $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 (as discussed further below), we 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 us 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 we retain control and consider as cash and cash equivalents, (ii) a minimum consolidated earnings before interest, taxes, depreciation and amortization (“EBITDA”) (as defined below) 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-cash and non-specified non-recurring charges.

As of December 31, 2025, we were in compliance with the covenants under the Credit Agreement.

Failure to comply with these covenants could limit the Company’s ability to access additional borrowings under the Revolving Credit Facility or could result in the acceleration of repayments of amounts outstanding under the facility.

Finance Leases

We enter into finance lease arrangements to obtain hard drives and related equipment for our data center operations.

S ee Note 10 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for our future minimum commitments related to our finance leases.

The weighted average discount rate for finance leases was 12.6% as of December 31, 2025.

For further information on our future minimum commitments on our operating leases, s ee “Item 8.

Financial Statement and Supplementary Data — Note 11.

Commitments and Contingencies” to our consolidated financial statements.

Operating Leases

We lease data center spaces and office space under non-cancelable operating leases with various expiration dates.

See Note 10 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further information on our future minimum commitments on our operating leases.

The weighted average discount rate for operating leases was 6.9% as of December 31, 2025.

In June 2025, we 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.

Purchase Commitments

In addition, we have purchase commitments that relate mainly to infrastructure agreements used to facilitate our operations.

As of December 31, 2024, we had non-cancelable purchase commitments of $1.0 million and $0.4 million payable for the years ending December 31, 2025 and 2026, respectively.

As of December 31, 2025, there are $2.5 million, $2.2 million, and $0.8 million payable for these commitments for the years ending December 31, 2026, 2027, and 2028, respectively.

Share Repurchase Program

In August 2025, our Board of Directors approved a share repurchase program authorizing us to repurchase up to $10.0 million of our Class A common stock through August 1, 2026.

The program is intended to offset dilution resulting from stock-based compensation.

Repurchases are to be funded from the proceeds of employee stock option exercises and from employee contributions under the 2021 Employee Stock Purchase Plan.

Repurchases may be made from time to time in open market transactions, pursuant to Rule 10b5-1 trading plans, or through other means, in accordance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended.

The timing, number of shares repurchased, and prices paid for the shares under this program will depend on 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 us to acquire any amount of Class A common stock.

During the year ended December 31, 2025, we repurchased a total of 256,549 shares of our Class A common stock for $2.0 million.

As of December 31, 2025, approximately $8.0 million remained available for repurchases under the program.

The following table shows a summary of our cash flows for the periods presente d:

Operating Activities

1 unchanged sentence

Our primary uses of cash from operating activities are for personnel-related expenses, sales and marketing expenses, infrastructure expenses, and overhead expenses.

Cash flows from operating activities primarily consist of our net loss adjusted for certain non-cash items, including stock-based compensation, depreciation, and amortization of property and equipment, amortization of capitalized internal-use software, net, noncash lease expense, and changes in operating assets and liabilities during each period.

For the year ended December 31, 2025, cash provided by operating activities was $23.5 million, which resulted from a net loss of $25.6 million, adjusted for non-cash charges of $58.5 million and net cash outflow of $9.3 million from changes in operating assets and liabilities.

Non-cash charges primarily consisted of $26.4 million for stock-based compensation expense, $25.6 million for depreciation and amortization expense, noncash lease expense on operating leases of $4.9 million, and a $1.0 million impairment loss on right-of-use assets primarily related to our restructuring activities.

The net cash outflow from changes in operating assets and liabilities was primarily due to a $4.5 million decrease in operating lease liabilities reflecting the timing of lease payments, a $2.7 million increase in other assets primarily related to employee sales commissions, a $1.7 million increase in accounts receivable driven by higher revenue from enterprise customers and the timing of billings and related collections, and a $1.5 million increase in prepaid expenses and other current assets primarily due to higher unbilled revenue.

For the year ended December 31, 2024, cash used in operating activities was $12.5 million, which resulted from a net loss of $48.5 million, adjusted for non-cash charges of $60.8 million and a net cash inflow of $0.2 million from changes in operating assets and liabilities.

4 unchanged sentences

Cash provided by operations increased during the year ended December 31, 2024, as compared to the same period in 2023 primarily due to our growing customer base, increased storage from new and existing customers and the price increase that began to take effect in October 2023, partially offset by increased expenditures related to managing and operating our co-location facilities, and increased spending in support of our expanded research and development and sales and marketing spending to support business growth.

For the year ended December 31, 2023, cash used in operating activities was $7.4 million, which resulted from a net loss of $59.7 million, adjusted for non-cash charges of $52.8 million and a net cash outflow of $0.4 million from changes in operating assets and liabilities.

Non-cash charges primarily consisted of $24.9 million for depreciation and amortization expense and $25.2 million for stock-based compensation expense.

The net cash outflow from changes in operating assets and liabilities was primarily the result of a $2.5 million decrease in operating lease liabilities, a $1.4 million decrease in

accrued expenses and other current liabilities, which decreased primarily due to our accrued compensation and due to timing of payment of our expenses, a $0.4 million increase in other assets, a $0.4 million increase in prepaid and other current assets and a $0.3 million decrease in accounts payable, offset in part by a $4.5 million increase of deferred revenue, which increased due to our growing customer base and upfront collections from our customers.

Cash used in operations decreased during the year ended December 31, 2023, as compared to the same period in 2022 primarily due to our growing customer base, increased storage from existing customers, and the price increase that began to take effect in October 2023, partially offset by increased expenditures related to managing and operating our co-location facilities, and increased spending in support of our expanded research and development and sales and marketing spending to support business growth.

Investing Activities

Critical Accounting Estimates

Our consolidated financial statements and the related notes thereto included elsewhere in this Annual Report on Form 10-K are prepared in accordance with GAAP.

The preparation of consolidated financial statements also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures.

We base our estimates on historical experience and on various other assumptions that we believe to be

reasonable under the circumstances.

Actual results could differ significantly from the estimates made by management.

To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations, and cash flows will be affected.

Our accounting estimates do not involve significant estimation uncertainty that may have or is reasonably likely to have a material impact on our financial condition or results of operations.

Additional information about estimates and other accounting policies are discussed in Note 2 to our accompanying consolidated financial statements.

Our consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K are prepared in accordance with GAAP.

The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures.

We evaluate our estimates and judgments on an ongoing basis, based on historical experience, current trends, and other factors that we believe are reasonable under the circumstances.

Actual results could differ materially from these estimates, and such differences could have a material impact on our financial condition, results of operations, and cash flows.

While our significant accounting policies are described in Note 2 to our consolidated financial statements, we believe the following accounting estimates involve the most significant judgments and assumptions used in the preparation of our consolidated financial statements and therefore represent our critical accounting estimates.

Useful Lives of Long-Lived Assets

Our long-lived assets primarily consist of data center equipment, servers, networking equipment, capitalized internal-use software, and certain right-of-use assets related to our lease arrangements.

These assets are recorded at cost and depreciated or amortized on a straight-line basis over their estimated useful lives.

Determining the appropriate useful lives of our long-lived assets requires significant judgment and is based on our expectations regarding the period over which the assets will provide economic benefit.

Factors considered in establishing useful lives include historical asset performance, technological changes, expected usage patterns, and anticipated maintenance or replacement cycles.

We review useful lives periodically and may revise them when warranted by changes in circumstances or new information.

Changes in estimated useful lives affect the timing of depreciation and amortization expense recognized in future periods.

Because depreciation is primarily included in cost of revenue, revisions to useful lives would impact future gross margin and operating results on a prospective basis.

During the second quarter of 2025, we completed a study on the useful lives of our property and equipment, resulting in an extension of the useful life of our infrastructure equipment.

Capitalization of Internal-Use Software

We capitalize certain costs related to the development of internal-use software that supports our Backblaze Storage Cloud platform and related products.

Capitalized costs primarily consist of personnel-related costs, including salaries, benefits, and stock-based compensation, incurred during the application development stage of software projects.

Capitalization begins when the preliminary project stage is complete and it is probable that the software will be completed and used for its intended purpose, and ceases when the software is substantially complete and ready for its intended use.

Significant judgment is required in determining whether a software project qualifies for capitalization, determining when capitalization should begin and end, and identifying and measuring the costs that qualify for capitalization.

We also estimate the expected useful lives of capitalized internal-use software and amortize these costs on a straight-line basis over the period in which the software is expected to provide economic benefit.

Changes in our estimates related to project scope, expected functionality, qualifying costs, or useful lives could materially affect the amount of costs capitalized, the timing of expense recognition, and our results of operations.

Capitalized internal-use software represents a significant asset on our consolidated balance sheets, and amortization of these costs is included primarily in cost of revenue.

If our assumptions regarding capitalization eligibility, project completion, or useful lives were to change, our operating results and gross margin could be materially impacted.

A hypothetical 10% increase or decrease in the amount of project costs capitalized for the year ended December 31, 2025 would have resulted in a corresponding decrease or increase of approximately $1.0 million in operating expenses for the period.

This provision allows an emerging growth company to delay the adoption of some accounting standards unless and until those standards would otherwise apply to private companies.

We have elected to use the extended transition period under the JOBS Act for the adoption of accounting standards until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act.

As a result, our consolidated financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

We have elected to use the extended transition period under the JOBS Act for the adoption of new or revised accounting standards and, as a result, we will adopt such standards on the dates applicable to private companies until we cease to be an emerging growth company on December 31, 2026, which is the last day of the fiscal year following the fifth anniversary of our initial public offering.
