#### PROXY STATEMENT FOR 2026 ANNUAL MEETING OF STOCKHOLDERS

#### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
This Proxy Statement is furnished in connection with solicitation of proxies by our Board of Directors for use at the 2026 Annual Meeting of Stockholders (the "Annual Meeting") to be held at 11:00 a.m. Pacific Time on Tuesday, May 26, 2026, and any postponements or adjournments thereof. The Annual Meeting will be a virtual meeting of stockholders, which will be conducted via a live audio webcast. You will be able to virtually attend the Annual Meeting, submit your questions and vote online during the meeting by visiting www.virtualshareholdermeeting.com/BLZE2026. Beginning on or about April 15, 2026, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials (the "Notice"), containing instructions on how to access this proxy statement for the 2026 Annual Meeting and our annual report for the year ended December 31, 2025 (the "Annual Report"). As used in this Proxy Statement, the terms "Backblaze," the "Company," "we," "us," and "our" mean Backblaze, Inc. unless the context indicates otherwise.

#### QUESTIONS AND ANSWERS ABOUT PROCEDURAL MATTERS

---

| | |
|:---|:---|
| **Q:**<br>| **Why are you holding a virtual meeting, and how can stockholders attend?**  |

---

---

| | |
|:---|:---|
| A:<br>| We have adopted a virtual meeting format for our Annual Meeting this year because we believe a virtual meeting provides expanded access, improved communication, increased opportunity for stockholder attendance and participation, and cost savings for our stockholders and the Company. To participate in our virtual Annual Meeting, including to vote, and to view the list of registered stockholders as of the record date during the meeting, visit http://www.virtualshareholdermeeting.com/BLZE2026 with your 16-digit control number provided with your Notice. If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, follow the instructions from your broker or bank.  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **What can I do if I need technical assistance during the Annual Meeting?**  |

---

A: If you encounter any difficulties accessing the virtual Annual Meeting during the check-in or meeting time, please call the technical support number that will be posted on the Annual Meeting log-in page.

We encourage you to access the Annual Meeting before the start time of 11:00 a.m. Pacific Time. Please allow ample time for online check-in, which will begin at 10:45 a.m. Pacific Time.

---

| | |
|:---|:---|
| **Q:**<br>| **Why did I receive the Notice?**  |

---

---

| | |
|:---|:---|
| A:<br>| In accordance with U.S. Securities and Exchange Commission ("SEC") rules, instead of mailing a printed copy of our proxy materials, we have elected to provide access to our proxy materials over the Internet. Accordingly, we have sent you the Notice because our Board of Directors is soliciting your proxy to vote at the Annual Meeting, including any adjournments or postponements thereof. All stockholders of record as of the close of business on April 1, 2026 (the "Record Date") will have the ability to access the proxy materials on a website referred to in the Notice or to request a printed set of these materials at no charge. You will not receive a printed copy of the proxy materials unless you specifically request one. Instead, the Notice instructs you how to access and review the proxy materials via the Internet, how to request a printed copy of the proxy materials and how to submit your proxy via the Internet or by telephone.  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **How do I request paper copies of the proxy materials?**  |

---

---

| | |
|:---|:---|
| A:<br>| You will not receive paper copies of the proxy materials in the mail unless you request them in accordance with the instructions in the Notice. If you would like to receive a printed copy of the proxy materials, please follow the instructions on the Notice for requesting the proxy materials, and we will promptly mail them to you.  |

---

In addition, by following the instructions in the Notice, you may request to receive future proxy materials on an ongoing basis (i) electronically by e-mail or (ii) in printed form by mail. Choosing to receive future proxy materials by e-mail will save the Company the cost of printing and mailing documents to stockholders and will reduce the impact of annual meetings on the environment. Your election to receive proxy materials by e-mail or by mail will remain in effect until you terminate it.

#### **TABLE OF CONTENTS**

---

| | |
|:---|:---|
| **Q:**<br>| **What proxy materials are available on the Internet?**  |

---

A: The proxy materials include:

&nbsp;&nbsp;&nbsp;&nbsp;• This Proxy Statement for the Annual Meeting; and

&nbsp;&nbsp;&nbsp;&nbsp;• The Annual Report, which consists of our Annual Report on Form 10-K for the year ended December 31, 2025.

The proxy materials are available at www.proxyvote.com.

---

| | |
|:---|:---|
| **Q:**<br>| **What information is contained in this proxy statement?**  |

---

---

| | |
|:---|:---|
| A:<br>| The information in this Proxy Statement relates to the proposals to be voted on at the Annual Meeting, the voting process, the compensation of our directors and certain of our executive officers, corporate governance, and certain other required information.  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **Who can vote at the Annual Meeting?**  |

---

---

| | |
|:---|:---|
| A:<br>| Only stockholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting. On the Record Date, there were 60,014,731 shares of our Class A common stock, par value $0.0001 per share ("Class A Common Stock"), outstanding and no shares of our Class B common stock, par value $0.0001 per share, outstanding. The holders of our Class A Common Stock have the right to one vote for each share of Class A Common Stock they held as of the Record Date.  |

---

*Stockholders of Record. If shares of our Class A Common Stock are registered directly in your name with our transfer agent, Equiniti Trust Company, LLC, you are considered the stockholder of record with respect to those shares, and the Notice was provided to you directly by us. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or to vote live at the Annual Meeting. Throughout this Proxy Statement, we refer to these registered stockholders as "stockholders of record."* 

*Street Name Stockholders. If shares of our Class A Common Stock are held on your behalf in a brokerage account or by a bank or other nominee, you are considered to be the beneficial owner of shares that are held in "street name," and the Notice was forwarded to you by your broker, bank or other nominee, who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee as to how to vote your shares. Beneficial owners are also invited to attend the Annual Meeting.* 

---

| | |
|:---|:---|
| **Q:**<br>| **How many shares must be present or represented to conduct business at the Annual Meeting?**  |

---

---

| | |
|:---|:---|
| A:<br>| A quorum is the minimum number of shares required to be present at the Annual Meeting for the meeting to be properly held under our amended and restated bylaws (the "Bylaws") and Delaware state law. The holders of a majority of the voting power of the shares of stock issued and outstanding and entitled to vote at the Annual Meeting, present in person or represented by proxy, shall constitute a quorum.  |

---

Under the General Corporation Law of the State of Delaware and our Bylaws, abstentions and broker "non-votes" are counted as present and entitled to vote and are, therefore, included for purposes of determining whether a quorum is present at the Annual Meeting.

A broker non-vote occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.

---

| | |
|:---|:---|
| **Q:**<br>| **How can I vote my shares at the Annual Meeting?**  |

---

---

| | |
|:---|:---|
| A:<br>| Shares held in your name as the stockholder of record may be voted at the Annual Meeting. You may vote electronically at the Annual Meeting by going to http://www.virtualshareholdermeeting.com/BLZE2026 and using your unique control number that was included in the Notice to log in. You will need your unique control number to authenticate into the Annual Meeting. Shares held beneficially in street name may be voted at the Annual Meeting only if you obtain a legal proxy from the broker, trustee or other nominee that holds your shares giving you the right to vote the shares.  |

---

------

**Even if you plan to virtually attend the Annual Meeting, we recommend that you vote in advance so that your vote will be counted if you later decide not to attend the meeting.** 

---

| | |
|:---|:---|
| **Q:**<br>| **How can I vote my shares without attending the Annual Meeting?**  |

---

---

| | |
|:---|:---|
| A:<br>| *For Stockholders of Record* — If you are a stockholder of record, there are three ways to vote without attending the Annual Meeting:  |

---

&nbsp;&nbsp;&nbsp;&nbsp;• *Via the Internet —* You may vote by proxy via the Internet by following the instructions provided on the Notice or, if you requested printed copies of the proxy materials by mail, on the proxy card. You will be asked to provide the 16-digit control number printed on the Notice or on your proxy card. Your vote must be received by 11:59 p.m. Eastern Time on May 25, 2026 to be counted.

&nbsp;&nbsp;&nbsp;&nbsp;• *By Telephone —* You may vote by proxy by telephone by following the instructions provided on the Notice or, if you requested printed copies of the proxy materials by mail, on the proxy card. You will be asked to provide the control number printed on the Notice or on your proxy card. Your vote must be received by 11:59 p.m. Eastern Time on May 25, 2026 to be counted.

&nbsp;&nbsp;&nbsp;&nbsp;• *By Mail —* If you requested and received printed copies of the materials by mail, you may vote by mail by timely completing, signing and dating the enclosed proxy card and returning it in the envelope provided.

*For Beneficial Owners — If you are a beneficial owner holding shares through a bank, broker or other nominee, please refer to the information forwarded by your bank or broker to see which voting options are available to you. You are also invited to attend the Annual Meeting; however, you may not vote your shares at the virtual Annual Meeting unless you obtain a legal proxy from your broker, bank, or other nominee.* 

---

| | |
|:---|:---|
| **Q:**<br>| **What proposals will be voted on at the Annual Meeting?**  |

---

---

| | |
|:---|:---|
| A:<br>| At the Annual Meeting, stockholders will be asked to vote on the following proposals:  |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) To elect one Class II director to the Board of Directors, Jocelyn Carter-Miller, to hold office until the Annual Meeting of Stockholders held in 2029; and

&nbsp;&nbsp;&nbsp;&nbsp;(2) To ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2026.

---

| | |
|:---|:---|
| **Q:**<br>| **What is the voting requirement to approve each of the proposals?**  |

---

---

| | |
|:---|:---|
| A:<br>| *Proposal One* — The election of directors requires a plurality of the votes of the shares present in person or represented by proxy at the Annual Meeting and entitled to vote on the election of directors. "Plurality" means that the individuals who receive the largest number of votes cast "for" are elected as directors. As a result, any shares not voted "for" a particular nominee (whether as a result of withholding, abstention, or a broker non-vote) will not be counted in such nominee's favor.  |

---

*Proposal Two — The affirmative vote of the holders of a majority of the voting power of the shares of stock entitled to vote on this proposal that are present or represented by proxy at the Annual Meeting and are voted is required to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm. Abstentions and broker non-votes will have no effect on the outcome of this proposal.* 

---

| | |
|:---|:---|
| **Q:**<br>| **How does the Board of Directors recommend that I vote?**  |

---

---

| | |
|:---|:---|
| A:<br>| Our Board of Directors unanimously recommends that you vote your shares:  |

---

&nbsp;&nbsp;&nbsp;&nbsp;• "FOR" the nominee for election as a Class II director named in Proposal One (Jocelyn Carter-Miller); and,

&nbsp;&nbsp;&nbsp;&nbsp;• "FOR" the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2026.

------

---

| | |
|:---|:---|
| **Q:**<br>| **What happens if I do not give specific voting instructions?**  |

---

A: *For Stockholders of Record* — If you are a stockholder of record and you:

&nbsp;&nbsp;&nbsp;&nbsp;• indicate when voting on the Internet or by telephone that you wish to vote as recommended by our Board of Directors; or

&nbsp;&nbsp;&nbsp;&nbsp;• sign and return a proxy card without giving specific voting instructions,

then the persons named as proxy holders will vote your shares in the manner recommended by our Board of Directors on all matters presented in this Proxy Statement and as the proxy holders may determine in their discretion with respect to any other matters properly presented for a vote at the Annual Meeting.

If you are a stockholder of record and you do not return a proxy card and do not vote your shares, no votes will be cast on your behalf on any of the items of business at the Annual Meeting.

*For Beneficial Owners — If you are a beneficial owner of shares held in street name and do not provide the organization that holds your shares with specific voting instructions then, under applicable rules, the organization that holds your shares may generally vote on "routine" matters, such as Proposal Two, but cannot vote on "non-routine" matters. If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, that organization will inform the inspector of election that it does not have the authority to vote on this matter with respect to your shares. This is generally referred to as a "broker non-vote."* 

---

| | |
|:---|:---|
| **Q:**<br>| **How may my brokerage firm or other intermediary vote my shares if I fail to provide timely directions?**  |

---

---

| | |
|:---|:---|
| A:<br>| Brokerage firms and other intermediaries holding shares of common stock in street name for customers are generally required to vote such shares in the manner directed by their customers. In the absence of timely directions, your broker will have discretion to vote your shares on our sole routine matter — the proposal to ratify the appointment of our independent registered public accounting firm. Your broker will not have discretion to vote on the following "non-routine" matter absent direction from you: the election of the Class II director.  |

---

**Please note that brokers may not vote your shares on the election of directors in the absence of your specific instructions as to how to vote, so if you are a beneficial owner, we encourage you to provide instructions to your broker regarding the voting of your shares.** 

---

| | |
|:---|:---|
| **Q:**<br>| **What happens if additional matters are presented at the Annual Meeting?**  |

---

---

| | |
|:---|:---|
| A:<br>| If any other matters are properly presented for consideration at the Annual Meeting, including, among other things, consideration of a motion to adjourn the Annual Meeting to another time or place (including, without limitation, for the purpose of soliciting additional proxies), the persons named in the proxy card and acting thereunder will have discretion to vote on those matters in accordance with their best judgment. We do not currently anticipate that any other matters will be raised at the Annual Meeting.  |

---

---

| | |
|:---|:---|
| **Q:**<br>| **Can I change or revoke my vote?**  |

---

---

| | |
|:---|:---|
| A:<br>| Subject to any rules your broker, trustee, or nominee may have, you may change your proxy instructions at any time before your proxy is voted at the Annual Meeting.  |

---

If you are a stockholder of record, you may change your vote by (i) filing with our Secretary, prior to your shares being voted at the Annual Meeting, a written notice of revocation or a duly executed proxy card, in either case dated later than the prior proxy card relating to the same shares, or (ii) by virtually attending the Annual Meeting and voting via the Internet in accordance with the instructions at http://www.virtualshareholdermeeting.com/BLZE2026 (although attendance at the Annual Meeting will not, by itself, revoke a proxy). A stockholder of record that has voted on the Internet or by telephone may also change his or her vote by later making a timely and valid Internet or telephone vote.

If you are a beneficial owner of shares held in street name, you may change your vote (i) by timely submitting new voting instructions to your broker, trustee or other nominee or (ii) if you have obtained a legal proxy from the broker, trustee or other nominee that holds your shares giving you the right to vote the shares, by attending

------

the Annual Meeting and voting via the Internet in accordance with the instructions at http://www.virtualshareholdermeeting.com/BLZE2026 (or as otherwise provided by the broker, trustee or other nominee consistent with the foregoing).

Any written notice of revocation or subsequent proxy card must be received by our Secretary prior to the taking of the vote at the Annual Meeting. Such written notice of revocation or subsequent proxy card should be hand delivered to our Secretary or should be timely sent so as to be delivered to our principal executive offices, Attention: Secretary.

---

| | |
|:---|:---|
| **Q:**<br>| **Who will bear the cost of soliciting votes for the Annual Meeting?**  |

---

---

| | |

Proposals to be presented at our 2027 Annual Meeting of Stockholders that are not intended for inclusion in the proxy statement must be submitted in accordance with the applicable advance notice provisions of our Bylaws. Our Bylaws provide that, if you wish to submit a proposal that is not intended for inclusion in next year's proxy materials or a proposal to nominate a director, you must do so no later than February 27, 2027 and not earlier than January 28, 2027, *provided, however*, that if our 2027 Annual Meeting of Stockholders is held before April 26, 2027 or after August 3, 2027, then your proposal must be received no earlier than the close of business on the 120th day prior to such meeting and not later than the close of business on the later of the 90th day prior to such meeting or the 10th day following the day on which notice or public announcement of the date of such meeting is first made.

---

---

| | |
|:---|:---|
| A:<br>| We have adopted a procedure called "householding," which the SEC has approved. Under this procedure, we deliver a single copy of the Notice and, if applicable, the proxy materials to multiple stockholders who share the same address unless we have received contrary instructions from one or more of the stockholders. This procedure reduces our printing costs, mailing costs, fees, and impact on the environment. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written request, we will deliver promptly a separate copy of the Notice and, if applicable, the proxy materials to any stockholder at a shared address to which we delivered a single copy of any of these documents. To receive a separate copy of the Notice, and, if applicable, the proxy materials, stockholders should send their requests to our principal executive offices, Attention: Secretary. Stockholders who hold shares in street name (as described above) may contact their brokerage firm, bank, broker-dealer, or other similar organization to request information about householding. Stockholders who currently receive multiple copies of the Notice at their address and would like to request "householding" of their communications should contact us, if they are record records, or their brokers, if they hold in street name.  |

#### PROPOSAL ONE

#### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

#### ELECTION OF DIRECTOR

#### General
Our Board of Directors (the "Board") may establish the authorized number of directors from time to time by resolution. Our Board currently consists of five members. Our directors hold office until their successors have been elected and qualified or appointed, or the earlier of their death, resignation or removal. Our Board is divided into three classes with staggered three-year terms. The Certificate of Incorporation and the Bylaws provide that only our Board can fill vacant directorships. Any additional directorships resulting from an increase in the authorized number of directors would be distributed pro rata among the three classes so that, as nearly as possible, each class would consist of one-third of the authorized number of directors.

#### Nominees
One Class II director has been nominated for election at the Annual Meeting, for a three-year term expiring in 2029. Upon the recommendation of our Nominating and Corporate Governance Committee, our Board has nominated Jocelyn Carter-Miller for election as the Class II director at the Annual Meeting. The term of office of the elected Class II director will continue until such director's term expires in 2029, or until such director's successor has been duly elected and qualified, or the earlier of her death, resignation or removal.

The person nominated for election has agreed to serve if elected. Directors are elected by a plurality of the votes properly cast in person or by proxy at the Annual Meeting. This means that the nominee receiving the highest number of "For" votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the nominee named below. However, if you are a street name stockholder, which means that your shares are held by a broker, bank or other nominee, your shares will not be voted for the election of directors unless you have provided voting instructions to your nominee.

#### Information Regarding the Nominees and the Continuing Directors
The biographies below include information, as of March 31, 2026, regarding the specific experience, qualifications, attributes or skills of each of our Class I, Class II and Class III directors.

At the Annual Meeting, the stockholders are being asked to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2026.

#### Pre-Approval of Audit and Non-Audit Services
Consistent with requirements of the SEC and the Public Company Accounting Oversight Board regarding auditor independence, our Audit Committee is responsible for the appointment, compensation and oversight of the work of our independent registered public accounting firm. In recognition of this responsibility, our Audit Committee, or the Chair if such approval is needed between meetings of the Audit Committee, generally pre-approves all audit and permissible non-audit services provided by the independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services. All services rendered by Deloitte & Touche LLP for the year ended December 31, 2025 and by BDO USA, P.C. for the year ended December 31, 2024 were pre-approved by our Audit Committee.

#### Change of Auditors
As previously reported on Form 8-K filed with the Securities and Exchange Commission on April 11, 2025, on April 8, 2025, we notified BDO USA, P.C. that it was dismissed as our independent registered public accounting firm, effective immediately. The decision to dismiss BDO USA, P.C. was approved by our Audit Committee.

The audit reports of BDO USA, P.C. for our consolidated financial statements for each of the two most recent fiscal years ended December 31, 2024 and December 31, 2023 did not contain an adverse opinion or a disclaimer of opinion nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. During our two most recent fiscal years ended December 31, 2024 and December 31, 2023, there were no disagreements (within the meaning of Item 304(a)(1)(iv) of Regulation S-K) on any matter of accounting principles or practices, financial statement disclosure, or auditing scope and procedures, which disagreement(s), if not resolved to BDO USA, P.C.'s satisfaction, would have caused it to make reference to the subject matter of the disagreement(s) in connection with its report.

During our fiscal years ended December 31, 2024 and December 31, 2023, there were no reportable events (as that term is defined in Item 304(a)(1)(v) of Regulation S-K), except for material weaknesses in our internal control over financial reporting, which were fully remediated as of December 31, 2024, related to: (i) our controls to allow sufficient and timely review of significant accounting transactions, account reconciliations and presentation of the statement of cash flows; (ii) our controls over certain equity transactions to allow management to timely identify errors related to the recording of those transactions; and (iii) our controls to allow sufficient and timely review of the key assumptions and mathematical accuracy of our going concern assessment. These reportable events were discussed between the Audit Committee and BDO USA, P.C., and we have authorized BDO USA, P.C. to respond fully to the inquiries of our new independent registered public accounting firm concerning these reportable events. All of the material weaknesses were remediated as of December 31, 2024.

We provided BDO USA, P.C. with a copy of the Current Report on Form 8-K filed on April 11, 2025 prior to its filing with the Securities and Exchange Commission ("SEC") and requested that BDO USA, P.C. furnish us with a letter addressed to the SEC stating whether or not BDO USA, P.C. agrees with the above statements. A copy of the letter from BDO USA, P.C. addressed to the SEC dated April 11, 2025 was filed with the Form 8-K as Exhibit 16.1 thereto.

On April 8, 2025, the Audit Committee approved the engagement of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2025, effective immediately.

During our two most recent fiscal years ended December 31, 2025 and December 31, 2024, neither us, nor anyone acting on our behalf, consulted with Deloitte & Touche LLP on (i) any matter regarding the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on our consolidated financial statements, and no written report or oral advice was provided to us by Deloitte & Touche LLP that was an important factor considered by us in reaching a decision as to any accounting, auditing or financial reporting issue, or (ii) any matter that was the subject of any disagreement (as described in Item 304(a)(1)(iv) of Regulation S-K and the related instructions thereto) or a reportable event (as defined in Item 304(a)(1)(v) of Regulation S-K).

#### REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2026.

#### **TABLE OF CONTENTS**

#### BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

#### Board Composition
Our Board currently consists of five members. Our directors hold office until their successors have been elected and qualified or appointed, or the earlier of their death, resignation or removal.

Our Board is divided into three classes with staggered three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election.

Directors in a particular class will be elected for three-year terms at the annual meeting of stockholders in the year in which their terms expire. As a result, only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Each director's term continues until the election and qualification of his or her successor, or the earlier of his or her death, resignation, or removal.

The classification of our Board may have the effect of delaying or preventing changes in our control or management.

Our Board has a diverse gender and racial or ethnic composition, including three women, one African American or Black, one Hispanic or Latinx, and one of two or more races or ethnicities.

#### Director Independence
Our Class A Common Stock is listed on the Nasdaq Global Market ("Nasdaq"). Under Nasdaq's rules, independent directors must comprise a majority of a listed company's board of directors within one year of the completion of an initial public offering. In addition, Nasdaq's rules require that, subject to specified exceptions, each member of a listed company's audit, compensation and corporate governance and nominating committees be independent. Audit committee members and compensation committee members must also satisfy the independence criteria set forth in Rule 10A-3 and Rule 10C-1, respectively, under the Exchange Act. Under Nasdaq's rules, a director will only qualify as an "independent director" if, in the opinion of that company's board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

To be considered to be independent for purposes of Rule 10A-3 and under Nasdaq's rules, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (2) be an affiliated person of the listed company or any of its subsidiaries.

To be considered independent for purposes of Rule 10C-1 and under Nasdaq's rules, the board of directors must affirmatively determine that each member of the compensation committee is independent, including a consideration of all factors specifically relevant to determining whether the director has a relationship to the company which is material to that director's ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: (i) the source of compensation of such director, including any consulting, advisory or other compensatory fee paid by the company to such director and (ii) whether such director is affiliated with the company, a subsidiary of the company or an affiliate of a subsidiary of the company.

Our Board undertook a review of its composition, the composition of its committees and the independence of our directors and considered whether any director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that Jocelyn Carter-Miller, Barbara Nelson, Earl E. Fry and Evelyn D'An, representing four (4) of our directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is "independent" as that term is defined under Nasdaq's rules.

The independent members of our Board hold, and are expected to continue to hold, separate regularly scheduled executive session meetings at which only independent directors are present.

------

#### **TABLE OF CONTENTS**

#### Board Leadership Structure
Under our Corporate Governance Policy and Guidelines, our Board has combined the roles of Chairperson and Chief Executive Officer, who is Gleb Budman. Our Board has determined that we would be best served by having a Chairperson with deep operational and strategic knowledge of our business. Our Board has also appointed Jocelyn Carter-Miller as our Lead Independent Director. Our Board has determined that we would be best served by also having a Lead Independent Director to be responsible for, among other things, conducting sessions with the independent directors as part of every Board meeting, calling special meetings of the independent directors, and chairing all meetings of the independent directors.

#### Role of the Board in Risk Oversight
One of the key functions of our Board is informed oversight of our risk management process. In particular, our Board is responsible for monitoring and assessing strategic risk exposure. Our executive officers are responsible for the day-to-day management of the material risks we face. Our Board administers its oversight function directly as a whole. Our Board also administers its oversight through its various standing committees that address risks inherent in their respective areas of oversight. For example, our Audit Committee is responsible for overseeing the management of risks associated with our financial reporting, accounting, and auditing matters as well as cybersecurity attacks; our Compensation Committee oversees the management of risks associated with our compensation policies and programs; and our Nominating and Corporate Governance Committee oversees the management of risks associated with director independence, conflicts of interest, composition and organization of our Board, and succession planning.

#### Board Committees
Our Board has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. Our Board may establish other committees to facilitate the management of our business from time to time. Our Board and its committees set schedules for meeting throughout the year and can also hold special meetings and act by written consent from time to time, as appropriate. Our Board expects to delegate various responsibilities and authority to committees as generally described below. It is expected that the committees will regularly report on their activities and actions to the full Board. Each member of each committee of our Board qualifies as an independent director in accordance with Nasdaq's listing standards. Each committee of our Board has a written charter approved by our Board. Copies of each committee charters have been posted on the *Governance—Governance Documents* portion of our website at https://ir.backblaze.com. Members serve on these committees until their resignation or until otherwise determined by our Board.

The following table provides membership information for each of such Board committees as of March 31, 2026:

#### Audit Committee

#### **TABLE OF CONTENTS**
Our Audit Committee assists our Board with its oversight of the integrity of our financial statements; our compliance with legal and regulatory requirements; the qualifications, independence, and performance of the independent registered public accounting firm; and the design and implementation of our risk assessment and risk management. Among other things, our Audit Committee is responsible for reviewing and discussing with our management the adequacy and effectiveness of our disclosure controls and procedures. The Audit Committee also discusses with our management and independent registered public accounting firm the annual audit plan and scope of audit activities, scope and timing of the annual audit of our financial statements, and the results of the audit, quarterly reviews of our financial statements and, as appropriate, initiates inquiries into certain aspects of our financial affairs. Our Audit Committee is responsible for establishing and overseeing procedures for the receipt, retention, and treatment of any complaints regarding accounting, internal accounting controls or auditing matters, as well as for the confidential and anonymous submissions by our employees of concerns regarding questionable accounting or auditing matters. In addition, our Audit Committee has direct responsibility for the appointment, compensation, retention, and oversight of the work of our independent registered public accounting firm. Our Audit Committee has sole authority to approve the hiring and discharging of our independent registered public accounting firm, all audit engagement terms and fees, and all permissible non-audit engagements with the independent auditor.

#### Compensation Committee
The members of our Compensation Committee are Jocelyn Carter-Miller, Earl E. Fry and Evelyn D'An. Ms. Carter-Miller is the Chair of the Compensation Committee. Our Board has determined that each member of our Compensation Committee is independent under the rules and regulations of the SEC and Nasdaq's listing standards applicable to compensation committee members. Our Compensation Committee assists our Board with its oversight of the forms and amount of compensation for our executive officers (including officers reporting under Section 16 of the Exchange Act), the administration of our equity and non-equity incentive plans for employees and other service providers and certain other matters related to our compensation programs. Our Compensation Committee, among other responsibilities, evaluates the performance of our Chief Executive Officer and, in consultation with him, evaluates the performance of our other executive officers (including officers reporting under Section 16 of the Exchange Act). Our Compensation Committee also oversees the management of risks associated with our compensation policies and programs. Our Compensation Committee met 8 times in 2025.

#### Compensation Committee Processes and Procedures
Our Compensation Committee intends to meet at least five times each year and may otherwise meet at such times and places as the committee determines. The agenda for each meeting is usually developed by the Chair of our Compensation Committee and members of the management team. Our Compensation Committee meets regularly in executive sessions without members of management present. From time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, provide financial or other background information or advice or otherwise participate in Compensation Committee meetings. In particular, our Compensation Committee consults with our Chief Executive Officer in connection with reviewing, recommending or determining our executive compensation policies. Nevertheless, our Chief Executive Officer may not be present during our Compensation Committee's executive sessions or during voting or deliberations of the Compensation Committee regarding such individual's compensation. The charter of our Compensation Committee grants the committee access to all of our books, records, facilities and personnel. In addition, our Compensation Committee has the authority, in its sole discretion, to retain or obtain the advice of compensation consultants, legal counsel, or other advisors of its choosing, and we must provide for appropriate funding, as determined by our Compensation Committee, for payment of reasonable fees to any such advisor retained by the committee. The Compensation Committee has direct responsibility for the appointment, compensation and oversight of the work of any such advisors engaged for the purpose of advising the committee. Under the charter of our Compensation Committee, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other advisor to the Compensation Committee, other than in-house legal counsel and certain other types of advisors, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the advisor's independence; however, there is no requirement that any advisor be independent.

During the year ended December 31, 2025, our Compensation Committee engaged the services of Compensia, Inc. ("Compensia"), a national compensation consulting firm, to advise our Compensation Committee regarding the

------

#### **TABLE OF CONTENTS**
amount and types of compensation provided to our executive officers and non-employee directors in 2025. Compensia generally does not provide any services to us other than the services provided to our Compensation Committee. Our Compensation Committee has assessed the independence of Compensia pursuant to SEC and Nasdaq rules and concluded that no conflict of interest exists that would prevent Compensia from independently representing our Compensation Committee. Working with Compensia, our Compensation Committee has approved a set of relevant peer companies by which to review and evaluate our executive compensation.

#### Compensation Committee Interlocks and Insider Participation
None of our executive officers currently serves, or in the past fiscal year has served, as a member of the board of directors or compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) of any other entity that has one or more executive officers serving on our Board or Compensation Committee.

#### Nominating and Corporate Governance Committee
The members of our Nominating and Corporate Governance Committee are Barbara Nelson, Jocelyn Carter-Miller, and Earl E. Fry. Ms. Nelson is the Chair of the Nominating and Corporate Governance Committee. Our Board has determined that each member of our Nominating and Corporate Governance Committee is independent under Nasdaq's listing standards applicable to nominating and corporate governance committee members. Our Nominating and Corporate Governance Committee, among other things, assists our Board with its oversight of and identification of individuals qualified to become members of our Board, consistent with criteria approved by our Board, and selects, or recommends that our Board selects, director nominees; develops and recommends to our Board a set of corporate governance guidelines; and oversees the evaluation of our Board. Our Nominating and Corporate Governance Committee also oversees the management of risks associated with director independence, conflicts of interest, composition and organization of our Board, and succession planning. Our Nominating and Corporate Governance Committee met 5 times in 2025.

#### Director Nominations Process
Our Board will evaluate candidates for membership on our Board, including candidates nominated or recommended by stockholders, based on criteria established by our Board and as set forth in our Director Nominations Policy and Procedures. As part of this process, our Board, with oversight of our Nominating and Corporate Governance Committee, will oversee a periodic evaluation of the performance of our Board as a whole, of each Board committee and of individual directors and of the qualifications and performance of directors eligible for reelection at the annual meeting of stockholders. Specifically, in its evaluation of director candidates, including directors eligible for reelection, our Board seeks to achieve a balance of knowledge, experience, and capability on the Board and considers the following: the current size and composition of our Board and the needs of our Board and its respective committees; legal and regulatory requirements for boards of directors; such issues as character, integrity, judgment, diversity, independence, area of expertise, corporate, industry and eco-system experience, length of service, potential conflicts of interest, availability, other commitments and the like; industry best practices; and such other factors as the Nominating and Corporate Governance Committee may consider appropriate. With respect to diversity, the Board believes that a diverse boardroom provides a number of benefits, including greater diversity of thought which can help lead to a stronger decision-making process, enhanced breadth of personal experiences and viewpoints, and better representation of different stockholders and other stakeholders. The Board and its committees consider the effectiveness of such policies and procedures as part of its annual evaluation process.

The Nominating and Corporate Governance Committee has established certain minimum qualifications for director candidates: (i) high personal and professional ethics and integrity, (ii) proven achievement and competence in the nominee's field and the ability to exercise sound business judgment, (iii) skills that are beneficial to those of existing Board members, (iv) the ability to assist and support management and make significant contributions to our success, and (v) an understanding of the responsibilities that are required of a member of our Board and the commitment of time and energy necessary to diligently carry out those responsibilities. In evaluating the candidates, the Nominating and Corporate Governance Committee does not assign any particular weighting or priority to various factors. With regard to candidates who are properly recommended by stockholders or by other means, the Board will review the qualifications of any such candidate, which review may, in the Nominating and Corporate Governance Committee's discretion, include interviewing references for the candidate, performing background checks, direct interviews with the candidate, or other actions that such committee deems necessary or proper.

------

#### **TABLE OF CONTENTS**
The Nominating and Corporate Governance Committee will apply these same principles when evaluating candidates to our Board who may be elected initially by the full Board to fill vacancies or add additional directors prior to the annual meeting of stockholders at which directors are elected. After completing its review and evaluation of director candidates, the Nominating and Corporate Governance Committee selects, or recommends to the full Board for selection, the director nominees. The Nominating and Corporate Governance Committee will also apply these same principles when evaluating candidates to our Board who are recommended by our stockholders in accordance with our policies and procedures.

It is the policy of our Board to consider recommendations for Board candidates from stockholders holding a voting interest of at least five percent (5%) of our fully diluted voting power continuously for at least twelve months prior to the date of the submission of the recommendation. Stockholder recommendations for candidates to our Board must be directed in writing to Backblaze, Inc. 2261 Market Street, STE 81006, San Francisco, California 94114, to the attention of either the General Counsel or our legal department, and must include the candidate's name, home and business contact information, detailed biographical data and relevant qualifications, a signed letter from the candidate confirming his or her willingness to serve, information regarding any relationships between the candidate and Backblaze, and evidence of the recommending person's ownership of our capital stock. Such recommendations must also include a statement from the recommending stockholder in support of the candidate, particularly within the context of the criteria for membership on our Board. The Nominating and Corporate Governance Committee may request additional information regarding recommended candidates.

Stockholder nominations to the Board must meet the requirements set forth in the Bylaws. Under these requirements, nominations for election to our Board may be made at a meeting of stockholders by any stockholder entitled to vote in the election of directors who provides timely written notice to our Secretary. This notice must contain specified information concerning the nominee and concerning the stockholder proposing the nomination. In order to be timely, a stockholder's notice must be delivered to or mailed and received by our Secretary at our principal executive offices within the time period specified in the Bylaws.

#### Code of Conduct
Our Board has adopted a Code of Conduct (the "Code"). The Code applies to all of our employees, officers, directors, contractors, consultants, suppliers and agents. The full text of the Code has been posted on the *Governance—Governance Documents* portion of our website at https://ir.backblaze.com. We intend to disclose future amendments to, or waivers of, the Code, as and to the extent required by SEC regulations, at the same location on our website identified above or in public filings.

#### Transactions in the Company's Securities
Our Board has adopted an Insider Trading Policy (the "Policy"), which applies to all of our directors, officers, employees and agents (such as consultants and independent contractors), as well as certain family members, economic dependents, and any other individuals or entities whose transactions in securities such individual influences, directs or controls. Under the Policy, such individuals are prohibited from transacting in publicly-traded options, such as puts and calls, and other derivative securities with respect to our securities, and such prohibition extends to any hedging or similar transaction designed to decrease the risks associated with holding our securities. Stock options, restricted stock units ("RSUs"), restricted stock, stock appreciation rights and other securities issued pursuant to our benefit plans or other compensatory arrangements with us are not subject to this prohibition. In addition, individuals subject to the Policy may not pledge our securities as collateral for loans.

#### Non-Employee Director Stock Ownership Guidelines
To help align our non-employee directors' interest with those of our stockholders, the Company maintains stock ownership guidelines, effective August 15, 2025, which require each non-employee director to maintain ownership in shares of the Company's common stock equal to five times his or her annual cash retainer. Each non-employee director has five years from the later of the policy's effective date or their date of appointment to achieve the applicable ownership threshold. Shares counting towards ownership targets include RSUs, whether vested or unvested. As of December 31, 2025, all directors either met the stock ownership guidelines or were on track to meet the guidelines within the applicable five-year window.

#### Equity Awards Grant Policy
We do not have any program, plan, or obligation that requires us to grant equity awards on specified dates, although historically we have granted such awards to our existing executive officers and employees at least annually

------

#### **TABLE OF CONTENTS**
and to newly-hired employees upon the commencement of their employment. Equity awards may occasionally be granted following a significant change in job responsibilities or to meet other special retention or performance objectives.

Authority to grant equity awards to our employees rests with the Compensation Committee. The Compensation Committee does not grant equity awards in anticipation of the release of material nonpublic information, and we do not time the release of material nonpublic information based on equity award grant dates. Under the terms of our 2021 Equity Incentive Plan and 2024 New Employee Equity Incentive Plan, pursuant to which new equity awards are granted, the exercise price of any option to purchase shares of our common stock awarded under the plan must be equal to at least 100% of the fair market value of our Class A Common Stock (which is determined based on the closing sales price of our Class A Common Stock on the Nasdaq Global Market) on the date of grant.

#### Meetings of the Board of Directors
The Board met 12 times during the year ended December 31, 2025. No director attended fewer than 75% of the total number of meetings of the Board or of any committees of the Board of which he or she was a member during the year ended December 31, 2025.

It is our policy that directors are invited and strongly encouraged to attend our annual meetings of stockholders. Of the five members of our Board who were then in office, all five attended our Annual Meeting of Stockholders in 2025.

#### Stockholder Communications with the Board of Directors
Stockholders wishing to communicate with our Board or with an individual member of our Board may do so by writing to the Board or to the particular director, care of the General Counsel by mail to our principal executive offices, Attention: General Counsel. The envelope should indicate that it contains a stockholder communication, and each such communication should set forth the name and address of the stockholder and the number of shares of our Class A Common Stock that are owned, of record and beneficially, by such stockholder. All such stockholder communications will be forwarded to the director or directors to whom the communications are addressed.

#### Director Compensation
The following table presents the total compensation, including equity awards, paid to each of our non-employee directors during the year ended December 31, 2025 for their service on our Board. We also reimburse our directors for expenses associated with attending meetings of our Board and its committees.

#### Non-Employee Director Compensation Policy
In April 2021, our Board approved a director compensation policy for non-employee directors to be effective in connection with our initial public offering. Pursuant to this policy, our non-employee directors receive following completion of the offering the compensation described below. No changes were made to our non-employee director compensation policy in 2025.

------

#### **TABLE OF CONTENTS**
*Cash Compensation* 

Each non-employee director receives an annual cash retainer of $35,000. Our Lead Independent Director is also paid an additional annual cash retainer of $15,000.

In addition to the annual cash retainer, each director receives the following annual cash amounts for service on Board committees:

---

| | | |
|:---|:---|:---|
| **Committee** | **Chairperson** | **Member**  |

All cash amounts are paid in arrears in quarterly installments.

*Equity Compensation* 

Each non-employee director that is initially appointed or elected as a member of our Board will receive an RSU award covering a number of shares of Class A Common Stock having a grant date value of $300,000, determined using the closing price of our Class A Common Stock on the grant date. Subject to the director's continuing service, the RSU award will vest in equal annual installments over a 3-year period, with vesting to occur on the anniversary of the grant date, which will be the date of the director's appointment or election.

Each non-employee director re-elected to our Board at, or otherwise continuing to serve as a director after, an annual meeting of our stockholders will also receive an RSU award covering a number of shares of Class A Common Stock having a grant date value of $150,000, determined using the closing price of our Class A Common Stock on the grant date, which shall be the date of the annual meeting of stockholders at which the election or re-election occurs. Such annual RSUs will vest on the earlier of the next following annual meeting of stockholders or the first anniversary of grant. Directors newly appointed to our Board between annual meetings of stockholders, receiving an automatic equity grant immediately following this offering as detailed above or who joined the Board within the prior 12 months to such annual meeting of stockholders, will receive an annual award prorated to reflect their time on the Board prior to the annual meeting of stockholders date.

Equity awards held by our non-employee directors will vest in full upon a change in control of the Company.

#### Narrative Explanation of Compensation Arrangements with our Named Executive Officers

#### Base Salaries and Annual Incentive Opportunities
The base salaries of all of our named executive officers are reviewed at least annually and adjusted when our Compensation Committee (or Board) determines an adjustment is appropriate.

In 2023, we adopted an annual bonus plan that is designed to incentivize and reward eligible employees, including our named executive officers, based on our achievement of certain financial metrics in the fiscal year and individual performance. The financial performance metrics were revenue and adjusted EBITDA. For more information about adjusted EBITDA, see the section in the Annual Report titled "Management's Discussion and Analysis of Financial Condition and Results of Operations—Non-GAAP Financial Measures—Adjusted EBITDA". The target bonus amounts are determined by the employee's level (up to 10%) and annual earnings, and the total bonus payout can range from zero to 200% of the target bonus depending on the final achievement against the performance metrics. The named executive officers each have a target bonus of 10% of their respective annual earnings. The actual achievement with respect to the financial performance metrics, and therefore the resulting payout, for the 2023 annual bonus plan was 150%.

In 2024, the annual bonus plan was designed to incentivize and reward eligible employees, including our named executive officers, based on our achievement of certain financial metrics in the fiscal year and individual performance. The financial performance metrics were annual revenue, annual adjusted and cash (including cash equivalents, restricted cash and short-term investments) as of year-end. The target bonus amounts were determined

------

#### **TABLE OF CONTENTS**
by the employee's level and annual earnings, and the total bonus payout could range from zero to 156% of the target bonus depending on the final achievement against the performance metrics. Mr. Budman, Mr. Suidan, and Ms. Cessna had a target bonus of 25%, 50% and 10%, respectively, of their respective base salary (calculated as of December 31, 2024 and pro-rated in the event of an employment start date during the year, which was the case for Mr. Suidan). The actual achievement with respect to the financial performance metrics, and therefore the resulting payout, for the 2024 annual bonus plan was 82.33%. The 2024 annual bonus was paid in the form of fully vested RSUs (each RSU being equivalent to one share of Class A Common Stock) based on the closing stock price on the date of grant (following our earnings announcement reporting the annual financial results).

The 2025 annual bonus plan was similar to the 2024 annual bonus plan, except that the financial performance metrics were based on annual revenue, annual adjusted free cash flow and annual recurring revenue ("ARR") as of year-end. ARR is defined as the monthly revenue as of the last month of the period, multiplied by 12. While the bonus program for 2025 initially contemplated settlement in a combination of cash and RSUs, the Compensation Committee subsequently determined that bonus awards for the period would be settled entirely in RSUs (each RSU being equivalent to one share of Class A Common Stock) based on the closing stock price on the date of grant (following our earnings announcement reporting the annual financial results). Mr. Budman, Mr. Suidan and Ms. Cessna had a target bonus of 75%, 50% and 30%, respectively, of their respective base salary (calculated as of December 31, 2025). The actual achievement with respect to the financial performance metrics, and therefore the resulting payout, for the 2025 annual bonus plan was 68%. The 2025 annual bonus was paid in the form of fully vested RSUs (each RSU being equivalent to one share of Class A Common Stock) based on the closing stock price on the date of grant (following our earnings announcement reporting the annual financial results).

#### Equity Compensation
Historically, we generally offered stock options to eligible employees, including our named executive officers, as the long-term incentive component of our compensation program. Our stock options allow our employees to purchase shares of our Class A Common Stock at a price equal to the fair market value of our Class A Common Stock on the date of grant. Our Compensation Committee determines the fair market value of our Class A Common Stock with respect to our stock option grants based on the closing price of our Class A Common Stock on the Nasdaq Global Market.

Since our initial public offering in November 2021, we have generally offered RSUs to eligible employees, including our named executive officers, as the long-term incentive component of our compensation program. Each RSU represents a contingent right to receive one share of Class A Common Stock upon vesting. Generally, RSUs granted to new hires vest in equal quarterly installments over 4 years, while those granted to existing employees vest quarterly over 2 or 3 years. The RSUs granted to new hires include a one-year cliff vest such that 25% of the total number of the shares vest on approximately the first year anniversary of the vesting commencement date of the award and the remainder of the shares vest in equal quarterly installments over the following 3 years.

#### Retirement Savings and Employee Benefits and Perquisites
We have established a 401(k) tax-deferred savings plan, which permits participants, including our named executive officers, to make contributions by salary deduction pursuant to Section 401(k) of the Internal Revenue Code. We are responsible for administrative costs of the 401(k) Plan. We make an annual contribution equal to 3% of each employee's base salary pursuant to the safe harbor provisions of our plan, subject to an applicable maximum contribution.

\* As more fully set forth in "*Security Ownership of Certain Beneficial Owners and Management*" in this Proxy Statement, Mr. Budman holds an aggregate beneficial ownership interest of 1,893,117 shares of Class A Common Stock, representing 3.2% of total voting power. 

#### Severance and Change in Control Benefits
We have entered into severance and change in control agreements with each named executive officer. The severance and change in control agreements will provide for payment of cash severance and acceleration of outstanding equity awards upon certain involuntary terminations.

*Involuntary Termination Outside of a Change in Control Period* 

If the named executive officer is subject to a termination without cause or a resignation for good reason, or the named executive officer's employment terminates due to death or disability, and such termination or resignation does not occur within 3 months prior to or 12 months after a change in control, then the named executive officer will receive a lump sum cash severance payment equal to (i) a number of months of his or her then-current base salary, (ii) a prorated portion of his or her annual target bonus and (iii) 12 months for Mr. Budman, and 6 months for Mr. Suidan, of the monthly premium for COBRA coverage for the officer and his or her eligible dependents. The number of months used to calculate the severance payment are the greater of (a) 12 months for Mr. Budman, as Chief Executive Officer, and 6 months for Mr. Suidan, and (b) one month for each year of continuous employment, with such number not to exceed 18 months.

*Involuntary Termination Within a Change in Control Period* 

If the named executive officer is subject to a termination without cause or a resignation for good reason, or the named executive officer's employment terminates due to death or disability, and such termination or resignation occurs within 3 months prior to or 12 months after a change in control, then (A) the named executive officer will receive a lump sum cash severance payment equal to (i) a number of months of his or her then-current base salary, (ii) a prorated portion of his or her annual target bonus, and (iii) 18 months for Mr. Budman, and 12 months for Mr. Suidan, of the monthly premium for COBRA coverage for the officer and his or her eligible dependents, and (B) one hundred percent (100%) of the shares subject to each then-outstanding equity award subject to time-based vesting held by the named executive officer shall become fully vested, and the level of achievement of performance

------

#### **TABLE OF CONTENTS**
goals applicable to each then-outstanding equity award subject to performance-based vesting held by the officer shall be deemed to equal the greater of (i) the target level of achievement and (ii) the actual level of achievement, to the extent determinable. The number of months used to calculate the severance payment will be 18 months for Mr. Budman, as Chief Executive Officer, and the greater of (a) 12 months for Mr. Suidan, and (ii) one month for each year of continuous employment, with such number not to exceed 18 months.

Receipt of the severance benefits is contingent upon the named executive officer's execution and non-revocation of a general release of claims and, if requested by our Board, resignation from the Board. The definitions of relevant terms are set forth in the severance and change in control agreement.

#### Emerging Growth Company Status
We are an "emerging growth company," as defined in the Jumpstart Our Business Startups Act of 2012. As an emerging growth company we are exempt from certain requirements related to executive compensation, including, but not limited to, the requirements to hold a non-binding advisory vote on executive compensation, to provide information relating to the ratio of total compensation of our Chief Executive Officer to the median of the annual total compensation of all of our employees, each as required by the Investor Protection and Securities Reform Act of 2010, which is part of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and to provide certain pay-versus-performance disclosures pursuant to Item 402(v) of Regulation S-K.

#### SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
The following table sets forth certain information with respect to the beneficial ownership of our Class A Common Stock as of March 14, 2026, for:

&nbsp;&nbsp;&nbsp;&nbsp;• each of our named executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;• each of our directors, including our one Class I director nominee

&nbsp;&nbsp;&nbsp;&nbsp;• all of our current executive officers and directors as a group; and

&nbsp;&nbsp;&nbsp;&nbsp;• each stockholder known by us to be the beneficial owner of more than 5% of our outstanding Class A Common Stock.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days and shares of Class A Common Stock underlying RSUs that may be settled within 60 days of March 14, 2026.

The percentage ownership columns in the table is based on 60,086,048 shares of our Class A Common Stock outstanding as of March 14, 2026. The table below is based upon information supplied by officers, directors and principal stockholders and Schedule 13Gs and 13Ds filed with the SEC through March 14, 2026.

Except as indicated in the footnotes below, we believe, based on the information furnished to us, that the persons and entities named in the table below have sole voting and investment power with respect to all Class A Common Stock that they beneficially own, subject to applicable community property laws.

Unless otherwise indicated, the business address of each beneficial owner listed in the table below is c/o Backblaze, Inc., 2261 Market Street, STE 81006, San Francisco, California 94114.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Consists of (i) 78,346 shares of our Class A Common Stock, and (ii) 34,200 shares of our Class A Common Stock issuable upon exercise of options exercisable within 60 days of March 14, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Consists of (i) 62,346 shares of our Class A Common Stock, and (ii) 34,200 shares of our Class A Common Stock issuable upon exercise of options exercisable within 60 days of March 14, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Consists of (i) 73,791 shares of our Class A Common Stock, and (ii) 34,200 shares of our Class A Common Stock issuable upon exercise of options exercisable within 60 days of March 14, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Consists of (i) 73,791 shares of our Class A Common Stock, and (ii) 34,200 shares of our Class A Common Stock issuable upon exercise of options exercisable within 60 days of March 14, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;(5) Consists of (i) 2,376,285 shares of our Class A Common Stock, and (ii) 136,800 shares of our Class A Common Stock issuable upon exercise of options exercisable within 60 days of March 14, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;(6) Based solely on the Schedule 13G filed by the stockholder on January 30, 2026. The principal business address of this stockholder is 100 Vanguard Blvd., Malvern, PA 19355. On March 26, 2026, The Vanguard Group filed an amendment to its Schedule 13G reporting 0% beneficial ownership of the Company's Class A Common Stock. We understand this reduction to zero reflects an internal realignment within Vanguard rather than a disposition of shares in the open market. In accordance with SEC Release No. 34-39538, certain subsidiaries or business divisions that formerly had, or were deemed to have, beneficial ownership with The Vanguard Group, Inc., will report beneficial ownership separately (on a disaggregated basis). The Company believes that one or more Vanguard subsidiaries may hold shares of the Company's Class A Common Stock and anticipates that such ownership will be reflected in future Schedule 13G filings by those subsidiaries.

#### CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

#### Policies and Procedures for Related Party Transactions
We have adopted a written related party transaction policy. The Audit Committee of our Board has the primary responsibility for the review, approval and oversight of any "related person transaction," which is any transaction, arrangement, or relationship (or series of similar transactions, arrangements, or relationships) in which we are, were, or will be a participant and the amount involved exceeds $120,000, and in which the related person had, has, or will have a direct or indirect material interest. Under our related party transaction policy, our management is required to submit any related party transaction not previously approved or ratified by our Audit Committee or our Board. In approving or rejecting the proposed transactions, our Audit Committee will take into account all of the relevant facts and circumstances available. Our Audit Committee will approve only those transactions that, as determined by our Audit Committee, are in, or are not inconsistent with, our best interests and the best interests of our stockholders.

Although we have not had a written policy until shortly before our initial public offering in November 2021 for the review and approval of transactions with related persons, our Board has historically reviewed and approved any transaction where a director or officer had a financial interest, including the transactions described above. Prior to approving such a transaction, the material facts as to a director's or officer's relationship or interest as to the agreement or transaction were disclosed to our Board. Our Board would take this information into account when evaluating the transaction and in determining whether such transaction was fair to us and in the best interest of all of our stockholders.

#### Certain Related Party Transactions
In addition to the compensation arrangements with directors and named executive officers described elsewhere in this Proxy Statement, the following is a description of each transaction since January 1, 2022 and each currently proposed transaction in which:

&nbsp;&nbsp;&nbsp;&nbsp;• we have been or are to be a participant;

&nbsp;&nbsp;&nbsp;&nbsp;• the amount involved exceeded or exceeds $120,000; and

&nbsp;&nbsp;&nbsp;&nbsp;• any of our directors, executive officers or holders of more than 5% of our outstanding capital stock, or any immediate family member of, or person sharing the household with, any of these individuals, had or will have a direct or indirect material interest.

#### Indemnification Agreements
We have entered, and intend to continue to enter, into separate indemnification agreements with each of our directors and executive officers, in addition to the indemnification provided for in the Certificate of Incorporation and the Bylaws. The indemnification agreements, the Certificate of Incorporation and the Bylaws require us to indemnify our directors, executive officers and certain controlling persons to the fullest extent permitted by Delaware law.

The Audit Committee has reviewed and discussed with our management and Deloitte & Touche LLP our audited financial statements for the year ended December 31, 2025.

#### DELINQUENT SECTION 16(a) REPORTS
Section 16(a) of the Exchange Act requires our directors and certain of our officers and any person who beneficially owns more than 10% of our Class A Common Stock to file with the SEC initial reports of beneficial ownership and reports of subsequent changes in their beneficial ownership of our Class A Common Stock. Such directors, executive officers and stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file. The SEC has designated specific due dates for these reports and we must identify in this Proxy Statement those filings that were not filed when due. Based solely on our review of copies of the reports filed with the SEC pursuant to Section 16(a) of the Exchange Act and the written representations of the reporting persons, we believe that all reporting requirements under Section 16(a) of the Exchange Act during 2025 were complied with by each of our directors and officers and each person who beneficially owned more than 10% of our Class A Common Stock, except for the following:

&nbsp;&nbsp;&nbsp;&nbsp;• On May 30, 2025, a Form 4 reporting the annual grant of RSUs to Earl E. Fry, a Class I Board member, was filed one day late due to administrative error.

&nbsp;&nbsp;&nbsp;&nbsp;• On March 3, 2025, a Form 4 reporting three transactions by Marc Suidan, our Chief Financial Officer, was filed late. These transactions consisted of (i) the grant of RSUs, and (ii) two sales undertaken to cover withholding tax obligations in connection with the vesting of RSUs.

&nbsp;&nbsp;&nbsp;&nbsp;• On March 3, 2025, a Form 4 reporting four transactions by Gleb Budman, our Chief Executive Officer and Chairperson of our Board of Directors, was filed late. These transactions consisted of (i) the withholding of shares of common stock to cover withholding tax obligations in connection with the vesting of RSUs, (ii) the grant of RSUs, and (iii) two sales undertaken to cover withholding tax obligations in connection with the vesting of RSUs.

&nbsp;&nbsp;&nbsp;&nbsp;• On March 3, 2025, a Form 4 reporting five transactions by Tina Cessna, our former Senior Vice President, Engineering, was filed late. These transactions consisted of (i) the withholding of shares of common stock to cover withholding tax obligations in connection with the vesting of RSUs, (ii) the grant of RSUs, (iii) two sales undertaken to cover withholding tax obligations in connection with the vesting of RSUs, and (iv) a market sale.

#### OTHER MATTERS
We know of no other matters to be submitted at the Annual Meeting. If any other matters properly come before the Annual Meeting, it is the intention of the persons named in the proxy card to vote the shares they represent as we may recommend.

It is important that your shares be represented at the Annual Meeting, regardless of the number of shares that you hold. You are, therefore, urged to vote at your earliest convenience on the Internet or by telephone as instructed, or by executing and returning a proxy card, if you have requested one, in the envelope provided.
