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, and (iv) adjusted free cash flow and adjusted free cash flow 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 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 adjusted gross margin and adjusted EBITDA margin 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 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, as this metric eliminates the effects of depreciation and amortization.

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.

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

We define non-GAAP net income (loss) as net income adjusted to exclude stock-based compensation, realized and unrealized gains and losses on foreign currency transactions, 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 into 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, payments on legal settlement costs, and payments on other non-recurring charges. Adjusted free cash flow margin is calculated as adjusted free cash flow divided by revenue.

Key Business Metrics:

Annual Recurring Revenue (ARR)

We define annual recurring revenue (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. ARR is calculated based on multiplying the monthly revenue from all Backblaze B2 and Computer Backup arrangements, which represent greater than 98% of our revenue for the periods presented for the last month of a period by 12. Our annual recurring revenue for Computer Backup and B2 Cloud Storage is calculated in the same manner as our overall annual recurring revenue based on the revenue from our Computer Backup and B2 Cloud Storage solutions, respectively.

Net Revenue Retention Rate (NRR)

To calculate the NRR for a specific quarter, we determine the revenue recognized in that quarter from customers who generated revenue during the same quarter of the previous year. This revenue is then divided by the revenue generated 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

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.

Number of Customers

We define a customer at the end of any period as a distinct account, as identified by a unique account identifier, that has paid for our cloud services, which makes up substantially all of our user base. In Q4 2023, we refined our customer definition to include end-user customers that purchase through a reseller. This resulted in no impact to previously reported metrics other than a 1% decrease to the 120% NRR metric reported for Q3 2023.

Annual Average Revenue Per User

We define annual average revenue per user (Annual ARPU) as the annualized value for the average revenue per customer. Annual ARPU is calculated by dividing our revenue for the last month of a period by the total number of customers as of the last day of the same period and then multiplying the resulting quotient by 12. Our annual average revenue per user for Computer Backup and B2 Cloud Storage is calculated in the same manner based on the revenue and number of customers from our Computer Backup and B2 Cloud Storage solutions, respectively.
