Exhibit 99.1

**Backblaze Announces Fourth Quarter and Full Year 2022 Financial Results**

*44% Revenue Growth in B2 Cloud Storage, 23% Revenue Growth Overall in Q4 2022*

**San Mateo, CA (**February 15, 2023**)**—Backblaze, Inc. (Nasdaq: BLZE), a leading specialized storage cloud platform, today announced results for its fourth quarter and year ended December 31, 2022.

"We were pleased to finish 2022 with strong Q4 overall revenue growth of 23% driven by an increasing proportion of our B2 Cloud Storage service, which grew 44% in Q4," said Gleb Budman, CEO of Backblaze. "We are excited as we begin 2023 as we see the opportunity to help more small and large businesses reduce the cost of their cloud infrastructure," continued Mr. Budman. "Given the uncertain macroeconomic environment, businesses have even more reason to seek cost savings with best-of-breed cloud services — and Backblaze provides them a solution with B2 Cloud Storage, which is 1/5th the price of traditional cloud storage providers such as Amazon S3. Further, B2 is very easy to use, saving users up to 90% of the time it takes to manage traditional cloud services."

"Turning to our own financial picture, as we continue to grow revenue, we're moderating expense growth and are targeting to approach adjusted EBITDA breakeven in Q4 of this year," continued Mr. Budman.

**Cautionary Note Regarding Forward-looking Statements**

This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which involve risks and uncertainties. These forward-looking statements are frequently 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," or other similar terms or expressions that relate to our future performance, expectations, strategy, plans or intentions, and include statements in the section titled "Financial Outlook" and statements regarding the use and impact of our IPO proceeds.

Our actual results could differ materially from those stated in or implied by the forward-looking statements in this press release due to a number of factors, including but not limited to: market competition, including competitors that may have greater size, offerings and resources; effectively managing growth; disruption in our service or loss of availability of customers' data; cyberattacks; ability to attract and retain customers; continued growth consistent with historical levels; ability to offer new features on a timely basis; material defects or errors in our software; supply chain disruption; ability to maintain existing relationships with partners and to enter into new partnerships; ability to remediate and prevent material weaknesses in our internal controls over financial reporting; retention of key employees; the impact of COVID-19 and its variants on our business and the business of our customers, vendors, supply chain and partners; litigation and other disputes; and general market, political, economic, and business conditions. Further information on these and additional risks, uncertainties, assumptions, and other factors that could cause actual results or outcomes to differ materially from those included in or implied by the forward-looking statements contained in this release are included under the caption "Risk Factors" and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2021, updates reflected in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2022, and other filings and reports we make with the SEC from time to time.

The forward-looking statements made in this release reflect our views as of the date of this press release. We undertake no obligation to update any forward-looking statements in this press release, whether as a result of new information, future events or otherwise.

**Non-GAAP Financial Measures**

To supplement the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we use non-GAAP adjusted gross margin and adjusted EBITDA 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 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 margin as gross profit, exclusive of stock-based compensation expense, depreciation expense of our property and equipment, and amortization expense of capitalized software included within cost of revenue, as a percentage of adjusted gross profit to revenue. We exclude stock-based compensation, which is a non-cash item, 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 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.

***Adjusted EBITDA***

We define adjusted EBITDA as net loss adjusted to exclude depreciation and amortization, stock-based compensation, interest expense, income tax provision, unrealized loss on SAFE, gain on extinguishment of debt and SAFE holder settlement. We use adjusted EBITDA to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that adjusted EBITDA, when taken together with our GAAP financial results, provides 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 to be an important measure because it helps illustrate underlying trends in our business and our historical operating performance on a more consistent basis.

**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 (and excludes Physical Media revenue), 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)***

Our overall net revenue retention rate (NRR) 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 Computer Backup and B2 Cloud Storage is calculated in the same

------

manner as our overall net revenue retention rate based on the revenue from our Computer Backup and B2 Cloud Storage solutions, respectively.

***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 serve 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.

***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.

***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.
