Non-GAAP Financial Measures

To supplement the financial measures, which are prepared and presented in accordance with generally accepted accounting principles in the United States (GAAP), we provide investors with non-GAAP financial measures including (i) adjusted gross profit (and margin), (ii) adjusted EBITDA and adjusted EBITDA margin, (iii) non-GAAP net income (loss) and non-GAAP net income (loss) per share, (iv) adjusted free cash flow and adjusted free cash flow margin, and (v) other Non-GAAP measures. These non-GAAP financial measures are not necessarily comparable to other companies and should be considered as a supplement to, not a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP. We present these non-GAAP measures because management believes they are a useful measure of our performance and provide an additional basis for assessing our operating results. Please see the appendix attached to this press release for a reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures.

A reconciliation of non-GAAP guidance measures to corresponding GAAP measures is not available on a forward-looking basis without unreasonable effort due to the uncertainty regarding, and the potential variability of, expenses and other factors in the future. For example, stock-based compensation expense-related charges are impacted by the timing of employee stock transactions, the future fair market value of our common stock, and our future hiring and retention needs, all of which are difficult to predict with reasonable accuracy and subject to constant change.

Adjusted Gross Profit and Margin

We believe adjusted gross profit (and margin), when taken together with our GAAP financial results, provides a meaningful assessment of our performance and is useful to us for evaluating our ongoing operations and for internal planning and forecasting purposes.

We define adjusted gross profit as gross profit, excluding stock-based compensation expense, depreciation and amortization and restructuring charges within cost of revenue. We define adjusted gross margin as a percentage of adjusted gross profit to revenue. We exclude stock-based compensation, which is a non-cash item, and restructuring charges because we do not consider these items as 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 profit (and margin) provides consistency and comparability with our past financial performance and facilitates period-to-period comparisons of operations.

Adjusted EBITDA and Adjusted EBITDA Margin

We define Adjusted EBITDA as net loss adjusted to exclude depreciation and amortization, stock-based compensation, interest expense, investment income, income tax provision, realized and unrealized gains and losses on foreign currency transactions, impairment of long-lived assets, restructuring charges, legal settlement costs, and other non-recurring charges. Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by revenues for the period. We use Adjusted EBITDA and Adjusted EBITDA Margin to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that Adjusted EBITDA and Adjusted EBITDA Margin, when taken together with our GAAP financial results, provide meaningful supplemental information regarding our operating performance by excluding certain items that may not be indicative of our business, results of operations, or outlook. We consider Adjusted EBITDA and Adjusted EBITDA Margin to be important measures because they help illustrate underlying trends in our business and our historical operating performance on a more consistent basis.

4

Non-GAAP Net Income (Loss) and Non-GAAP Net Income (Loss) Per Share

We define non-GAAP net income (loss) as net income (loss) adjusted to exclude stock-based compensation, realized and unrealized gains and losses on foreign currency transactions, impairment of long-lived assets, restructuring charges, legal settlement costs, and other items we deem non-recurring. Non-GAAP net income (loss) per share is defined as non-GAAP net income (loss) divided by basic and diluted weighted average common shares outstanding. We believe that non-GAAP net income (loss) and non-GAAP net income (loss) per share, when taken together with our GAAP financial results, provide meaningful supplemental information regarding our operating performance by excluding certain items that may not be indicative of our business, results of operations, or outlook.

Adjusted Free Cash Flow and Adjusted Free Cash Flow Margin

We believe that Adjusted Free Cash Flow and Adjusted Free Cash Flow Margin are useful metrics for assessing liquidity that provide information to management and investors about the cash generated from our core operations that can be reinvested in the business. However, these measures should not replace cash flows from operations as a liquidity benchmark. One limitation of these metrics is that they do not reflect our future contractual commitments, nor do they capture the overall changes in our cash balance during a specific period. Nonetheless, we believe that Adjusted Free Cash Flow and Adjusted Free Cash Flow Margin are key metrics providing insight on our financial trajectory that helps us make informed decisions as we work towards sustainable positive cash flow.

We define adjusted free cash flow as net cash provided by operating activities less purchases of property and equipment, capitalized internal-use software costs, principal payments on finance leases and lease financing obligations, as reflected in our consolidated statements of cash flows, and excluding payments on restructuring charges, legal settlement payments, and payments on other non-recurring charges. Adjusted free cash flow margin is calculated as adjusted free cash flow divided by revenue.

Other Non-GAAP Measures

Adjusted Cost of Revenue and Adjusted Operating Expenses

Adjusted research and development, adjusted sales and marketing, and adjusted general and administrative (collectively, “adjusted operating expenses”) and adjusted cost of revenue are non-GAAP financial measures that we define as each respective GAAP expense category excluding stock-based compensation expense, depreciation and amortization, restructuring costs, and other non-recurring charges. These measures provide management with greater transparency into the underlying trends in our business by facilitating period-to-period comparisons of our ongoing cost structure, excluding the impact of certain non-cash or non-recurring items that may not be indicative of our operating performance. These measures are intended to assist in forecasting and budgeting by providing greater visibility into our normalized expense base.

Key Business Metrics:

Annual Recurring Revenue (ARR)

We define ARR as the annualized value of all Backblaze B2 and Computer Backup arrangements as of the end of a period. Given the renewable nature of our business, we view ARR as an important indicator of our financial performance and operating results, and we believe it is a useful metric for internal planning and analysis. For subscription-based arrangements, ARR is calculated by multiplying the monthly revenue for the last month of a period by 12. For consumption-based arrangements, ARR is calculated by multiplying average daily revenue for the last month of a period by 365. Total Company ARR represents the annualized value of all B2 Cloud Storage consumption- and subscription-based arrangements and Computer Backup subscription-based arrangements as of the end of a period.

5

Beginning in the first quarter of 2026, to improve comparability between periods, we revised our methodology for calculating ARR for our consumption-based arrangements to use a daily revenue rate during the last month of the period rather than a monthly rate. Prior period ARR amounts presented have been recast to conform to the current period presentation.

Net Revenue Retention Rate (NRR)

To calculate 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.

Beginning in the first quarter of 2026, we are presenting NRR using a single-quarter calculation, comparing current quarter revenue to the corresponding prior year quarter, rather than an average of quarterly rates over the prior four quarters, in order to provide a more current measure of customer retention. Prior period NRR amounts have been recast to conform to the current period presentation.

Gross Customer Retention Rate

We use gross customer retention rate to measure our ability to retain our customers. 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 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 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.

Backblaze ©2026 | 2 Cautionary Note Regarding Forward-Looking Statements This presentation contains forward-looking statements, which involve risks and uncertainties. These forward-looking statements are generally identified by the use of forward-looking terminology, including the terms “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “likely,” “may,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “target,” “will,” “would” and, in each case, their negative or other various or comparable terminology. All statements other than statements of historical facts contained in this presentation, including statements regarding our strategy, future operations, future financial position, future revenue, projected costs, planned investments and initiatives, prospects, plans, objectives of management and general economic trends and trends in the industry and markets are forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results to differ materially from any future results expressed or implied by the forward-looking statements, including that our AI customer revenue is early-stage and widespread adoption is uncertain; we may not achieve the growth rates implied by current trends; estimates of addressable market size and market opportunity are based on internal assumptions and third-party data that may prove inaccurate or may not reflect actual market conditions; our sales and marketing and cost-saving initiatives may not achieve their intended results; new features and price changes may not have the anticipated impact; supply availability, volatility and pricing may adversely affect our business; our recently announced strategic agreement with CoreWeave involves a new delivery model and is subject to risks related to customer concentration, ramp timing, consumption levels, and our ability to scale operations, any of which could cause actual revenue to differ from contracted amounts. Additional risks are set forth under “Risk Factors” in our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q. These forward-looking statements reflect our views with respect to future events as of the date of this presentation and are based on assumptions and subject to risks and uncertainties. Given these uncertainties, you should not place undue reliance on these forward-looking statements. We undertake no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise after the date of this presentation, except as required by applicable law. Non-GAAP Financial Measures To supplement the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we use non-GAAP Adjusted Gross Profit and Margin, non-GAAP Net Income (Loss), non-GAAP Net Income (Loss) per share, Adjusted EBITDA and Margin, and Adjusted Free Cash Flow and Margin. These non-GAAP financial measures exclude certain items and are not prepared in accordance with GAAP; therefore, the information is not necessarily comparable to other companies and should be considered as a supplement to, not a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP. We present these non-GAAP measures because management believes they are a useful measure of the Company’s performance and provide an additional basis for assessing our operating results. Please see the Appendix attached to this presentation for a reconciliation of non-GAAP Adjusted Gross Margin, non-GAAP Net Income, Adjusted EBITDA Margin and Adjusted Free Cash Flow to the most directly comparable GAAP financial measures.

A reconciliation of non-generally accepted accounting principles (GAAP) guidance measures to corresponding GAAP measures for historical results is provided in the Appendix to this presentation.

The revenue outlook for fiscal year 2026 also reflects a narrowed range of total Company revenue from the previously announced outlook. These forward-looking statements reflect our views with respect to future events as of the date of this presentation and are based on assumptions and subject to risks and uncertainties, and actual results may differ materially. A reconciliation of Adjusted EBITDA Margin guidance to GAAP net loss margin is not available on a forward-looking basis without unreasonable effort because certain reconciling items, including stock-based compensation expense, restructuring charges, depreciation and amortization, interest expense, and income tax provisions cannot be reasonably predicted due to their inherent uncertainty and variability. These items could individually or in the aggregate be material to the Company's reported GAAP results. Revenue ($M) Adj. EBITDA Margin

Backblaze ©2026 | 20 Q&A

Backblaze ©2026 | 21 Thank You!

Backblaze ©2026 | 22 Appendix

Backblaze ©2026 | 23 ● “ARR” means Annual Recurring Revenue. For subscription-based arrangements, ARR is calculated by multiplying the monthly revenue for the last month of a period by 12. Beginning in the first quarter of 2026, to improve comparability between periods, we revised our methodology for calculating annual recurring revenue for our consumption-based arrangements to use a daily revenue rate during the last month of the period rather than a monthly rate. Prior period ARR amounts presented have been recast to conform to the current period presentation. ● “Gross Customer Retention” is used to measure our ability to retain our customers and is based on 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. ● “NRR” means Net Revenue Retention. To calculate 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. Beginning in the first quarter of 2026, we are presenting NRR using a single-quarter calculation, comparing current quarter revenue to the corresponding prior year quarter, rather than an average of quarterly rates over the prior four quarters, in order to provide a more current measure of customer retention. Prior period NRR amounts have been recast to conform to the current period presentation. Definitions

Backblaze ©2026 | 24 ● “Customer” means a customer at the end of any period as a distinct end user, as identified by a unique account identifier, which makes up substantially all of our user base. ● “Adjusted EBITDA” is defined as net loss adjusted to exclude depreciation and amortization, stock-based compensation, interest expense, investment income, income tax provision, realized and unrealized gains and losses on foreign currency transactions, impairment of long-lived assets, restructuring charges, legal settlement costs, and other non-recurring charges. Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by revenues for the period. We use Adjusted EBITDA and Adjusted EBITDA Margin to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that Adjusted EBITDA and Adjusted EBITDA Margin, when taken together with our GAAP financial results, provide meaningful supplemental information regarding our operating performance by excluding certain items that may not be indicative of our business, results of operations, or outlook. We consider Adjusted EBITDA and Adjusted EBITDA Margin to be important measures because they help illustrate underlying trends in our business and our historical operating performance on a more consistent basis. ● “Adjusted Free Cash Flow” We define adjusted free cash flow as net cash provided by operating activities less purchases of property and equipment, capitalized internal-use software costs, principal payments on finance leases and lease financing obligations, as reflected in our consolidated statements of cash flows, and excluding payments on restructuring charges, legal settlement payments, and payments on other non-recurring charges. Adjusted free cash flow margin is calculated as adjusted free cash flow divided by revenue. Definitions

Backblaze ©2026 | 25 ● “Non-GAAP Net Income (Loss)” We define non-GAAP net income (loss) as net income (loss) adjusted to exclude stock-based compensation, realized and unrealized gains and losses on foreign currency transactions, impairment of long-lived assets, restructuring charges, legal settlement costs, and other items we deem non-recurring. Non-GAAP net income (loss) per share is defined as non-GAAP net income (loss) divided by basic and diluted weighted average common shares outstanding. We believe that non-GAAP net income (loss) and non-GAAP net income (loss) per share, when taken together with our GAAP financial results, provide meaningful supplemental information regarding our operating performance by excluding certain items that may not be indicative of our business, results of operations, or outlook. ● “Adjusted Gross Profit (and Margin)” We define adjusted gross profit as gross profit, excluding stock-based compensation expense, depreciation and amortization and restructuring charges within cost of revenue. We define adjusted gross margin as a percentage of adjusted gross profit to revenue. 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 profit (and margin) provides consistency and comparability with our past financial performance and facilitates period-to-period comparisons of operations. Definitions
