Important Notice Regarding the Availability of Proxy Materials for the Stockholders’ Meeting to Be Held on Thursday, May 16, 2024 at 11:00 a.m. Pacific Time online at www.virtualshareholdermeeting.com/BLZE2024.

This proxy statement is furnished in connection with solicitation of proxies by our Board of Directors for use at the 2024 Annual Meeting of Stockholders (the “Annual Meeting”) to be held at 11:00 a.m. Pacific Time on Thursday, May 16, 2024, 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/BLZE2024. Beginning on or about April 5, 2024, 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 2024 Annual Meeting and our annual report for the year ended December 31, 2023 (the “Annual Report”). As used in this proxy statement, the terms “Backblaze,” “Company,” “we,” “us,” and “our” mean Backblaze, Inc. unless the context indicates otherwise.

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.

Two Class III directors have been nominated for election at the Annual Meeting, each for a three-year term expiring in 2027. Upon the recommendation of our Nominating and Corporate Governance Committee, our Board has nominated Gleb Budman and Evelyn D’An for election as Class III directors at the Annual Meeting. The term of office of each elected Class III director will continue until such director’s term expires in 2027, or until such director’s successor has been duly elected and qualified, or the earlier of his or her death, resignation or removal.

Each person nominated for election has agreed to serve if elected. Directors are elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. This means that nominees 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.

The biographies below include information, as of March 21, 2024, regarding the specific experience, qualifications, attributes or skills of each of our Class I, Class II and Class III directors.

Gleb Budman is one of our co-founders and has served as our Chief Executive Officer since 2007. Mr. Budman has also served as a member of our Board since 2009 and Chairperson since January 2021.

Mr. Budman also previously founded two other startup companies. Mr. Budman earned a M.B.A. and B.S. in Mechanical Engineering from the University of California, Berkeley. We believe that Mr. Budman is qualified to serve as a member of our Board because of his extensive experience in leadership roles at various technology companies, and the continuity that he brings to our Board as our co-founder and Chief Executive Officer.

We believe Mr. Fry is qualified to serve as a member of our Board because of his significant professional experience in the areas of finance, accounting and audit oversight, both as a director and executive, as well as his substantial experience with respect to the software and cloud businesses, which allows him to contribute valuable insight and perspective.

There are no family relationships among any of our directors or executive officers. See “Board of Directors and Corporate Governance” and “Board of Directors and Corporate Governance—Director Compensation” below for additional information regarding our Board.

Our Audit Committee has selected the firm of BDO USA, P.C., independent registered public accounting firm, to audit our financial statements for the year ending December 31, 2024. BDO USA, P.C. has audited our financial statements since the year ended December 31, 2019.

Notwithstanding its selection and even if our stockholders ratify the selection, our Audit Committee, in its discretion, may appoint another independent registered public accounting firm at any time during the year if the Audit Committee believes that such a change would be in the best interests of us and our stockholders.

At the Annual Meeting, the stockholders are being asked to ratify the appointment of BDO USA, P.C. as our independent registered public accounting firm for the year ending December 31, 2024. Our Audit Committee is submitting the selection of BDO USA, P.C. to our stockholders because we value our stockholders’ views on our independent registered public accounting firm and as a matter of good corporate governance. We expect that representatives of BDO USA, P.C. will be present at the Annual Meeting, and they will have an opportunity to make statements and will be available to respond to appropriate questions from stockholders.

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 in person or represented by proxy at the meeting and are voted will be required to ratify the selection of BDO USA, P.C..

The following table sets forth all fees incurred for professional audit services and other services rendered by BDO USA, P.C. during the years ended December 31, 2023 and 2022 (in thousands):

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 BDO USA, P.C. for the years ended December 31, 2022 and 2023 were pre-approved by our Audit Committee.

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.

The following matrix presents the diverse composition of our Board as of the date of this proxy statement:

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

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.

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.

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 of directors. 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—Documents & Charters 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 committee as of March 21, 2024:

The members of our Audit Committee are Evelyn D’An, Earl E. Fry, Jocelyn Carter-Miller and Barbara Nelson. Ms. D’An is the chair of the Audit Committee. Our Board has determined that each member of our Audit Committee is independent under the rules and regulations of the SEC and Nasdaq’s listing standards applicable to audit committee members. Our Board has also determined that each member of the Audit Committee can read and understand fundamental financial statements and qualifies as an audit committee financial expert within the meaning of SEC regulations and meets Nasdaq’s financial sophistication requirements. Our Audit Committee met 14 times in 2023.

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. Our Audit Committee reviews and oversees all related person transactions in accordance with our policies and procedures. Our Audit Committee also reviews the Company’s cybersecurity and other information technology risks.

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 10 times in 2023.

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, 2023, our Compensation Committee engaged the services of Compensia, Inc. (“Compensia”), a national compensation consulting firm, to advise our Compensation Committee regarding the amount and types of compensation provided to our executive officers and non-employee directors in 2023. 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.

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.

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 6 times in 2023.

Our Board will evaluate candidates for membership on our board of directors, 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 of directors seeks to achieve a balance of knowledge, experience, and capability on the board of directors 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.

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 of directors 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. 201 Baldwin Ave., San Mateo, CA 9440, 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 of directors 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.

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—Documents & Charters 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.

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 this 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, 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.

The Board met 6 times during the year ended December 31, 2023. 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, 2023.

It is our policy that directors are invited and strongly encouraged to attend our annual meetings of stockholders. Of the six members of our Board who were then in office, all six attended our Annual Meeting of Stockholders in 2023.

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 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.

The following table presents the total compensation, including equity awards, paid to each of our non-employee directors during the year ended December 31, 2023 for their service on our Board. We also reimburse our directors for expenses associated with attending meetings of our Board and its committees.

Directors who are also our employees or officers receive no additional compensation for their service as directors while employed by the Company. Specifically, Mr. Budman, a current director and current employee, did not receive additional compensation for his service as a director in 2023. See the section titled “Executive Compensation” elsewhere in this proxy statement for additional information about the compensation of Mr. Budman, who was also a named executive officer in 2023.

Prior to our initial public offering in November 2021, we did not implement a formal policy with respect to compensation payable to our directors for their service on our Board. 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 2023.

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:

All cash amounts are paid in arrears in quarterly installments.

Each non-employee director serving on our Board as of immediately following our initial public offering, who also served on our Board for at least nine months prior to our initial public offering, was granted an RSU award for 9,375 shares of our Class A Common Stock (reflecting $150,000 divided by the Company’s initial public offering price). Subject to the director’s continuing service, the RSU award will vest on the one-year anniversary of the grant date, which was the effective date of the registration statement on Form S-8 that we filed on November 12, 2021.

Each non-employee director initially appointed or nominated as a member of our Board after our initial public offering will receive an RSU award covering a number of shares of 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 nomination. Each non-employee director elected or 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 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 at which the election or re-election occurs. Such annual RSUs will vest on the earlier of the next following annual shareholders meeting or the first anniversary of grant. Directors newly appointed to our Board between annual stockholder meetings, 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 stockholder meeting date or the date of the equity award immediately following this offering, as the case may be.

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

The following table provides information concerning our executive officers as of March 21, 2024:

The following table shows information regarding the compensation of our principal executive officer and our two most highly compensated executive officers (other than our chief executive officer) who were serving as executive officers as of December 31, 2023, whom we refer to herein as our “named executive officers.”

The base salaries of all of our named executive officers are reviewed from time to time and adjusted when our Board or the Compensation Committee determines an adjustment is appropriate. In addition, all eligible employees, including our named executive officers, were entitled to receive a cash bonus in equal amounts based on a percentage of our cash sales during the year.

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%.

The 2024 annual bonus plan is similar to the 2023 annual bonus plan, except that the financial performance metrics are based on revenue, adjusted EBITDA and the amount of cash (including cash equivalents, restricted cash and short-term investments) as of year-end. In addition, the named executive officers each have a 2024 target bonus of 10% of their respective annual earnings, except for Mr. Budman who has a 2024 target bonus of 25% of his respective annual earnings.

Historically, we generally offered stock options to our 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 common stock at a price equal to the fair market value of our common stock on the date of grant. Our Compensation Committee determines the fair market value of our 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. Generally, our stock options granted to employees vest up to 25% of the total number of option shares on the first anniversary of the award and in equal monthly installments over the following 36 months.

Since our initial public offering in November 2021, we have generally offered RSUs to our 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, our RSUs granted to employees vest in equal quarterly installments over 4 years, however, 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 award and the remainder of the shares vest in equal quarterly installments over the following 36 months.

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.

Our named executive officers are eligible to participate in our health and welfare plans to the same extent as are full-time employees generally. We generally do not provide our named executive officers with other perquisites or personal benefits.

The following table sets forth information regarding each unexercised option and all unvested stock held by each of our named executive officers as of December 31, 2023.

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.

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 each of Mr. Patchel and Ms. Cessna, 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 each of Mr. Patchel and Ms. Cessna, and (b) one month for each year of continuous employment, with such number not to exceed 18 months.

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 each of Mr. Patchel and Ms. Cessna, 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 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 each of Mr. Patchel and Ms. Cessna, 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.

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.

The following table sets forth certain information with respect to the beneficial ownership of our Class A Common Stock as of March 8, 2024, for:

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 8, 2024.

The percentage ownership columns in the table is based on 41,339,176 shares of our Class A Common Stock outstanding, in each case, as of March 8, 2024.

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., 201 Baldwin Ave., San Mateo, CA 94401.

The following table provides certain information as of December 31, 2023 with respect to our equity compensation plans. All of our equity compensation plans have been approved by our stockholders.

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.

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:

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.

In August 2021, we issued $10.0 million of convertible notes (which we also refer to as a Simple Agreement for Future Equity agreement (“SAFE”)) in a private financing round. In July 2022, we received a demand letter from the investors that entered into SAFE agreements with us in August 2021, which related to a contractual dispute in connection with the SAFE transaction. The SAFE holders sought a refund of their original investment of $10.0 million. In February 2023, we settled with the SAFE holders for a full release of all claims related to the SAFE transaction for a one-time payment in the amount of $1.5 million in aggregate. TMT Investments PLC, which was a greater than 5% stockholder, was a party to the settlement and received a pro-rata payment of $0.3 million as part of the SAFE settlement.

Pursuant to existing severance agreements, each of Tim Nufire, a Company founder who was also a director and a greater than 5% stockholder , and Brian Wilson, a Company founder who was also a director, executive officer and greater than 5% stockholder, received the following severance benefits in connection with their

termination of employment from the Company on January 15, 2023 and February 28, 2023, respectively, in exchange for a release of any claims and other covenants: (a) a lump sum cash severance payment equal to (i) 15 months of base salary for Mr. Nufire and 16 months of base salary for Mr. Wilson based on one month per year of employment with us) and (ii) their respective 2023 target bonus (equal to ten percent of their respective annualized salary) prorated for the number of days each served as an employee in 2023, and (b) reimbursement of COBRA health insurance premiums for a period of six months following their respective date of termination. Charles Jones, a Company founder who was then a greater than 5% stockholder, also received a severance payment on the same terms and conditions as set forth above in connection with his termination from us on January 15, 2023.

Yan Budman, the brother of Gleb Budman, our Chief Executive Officer and Chairperson , is a partner and Chief Strategy Officer at Meaningful Works, Inc. (“Meaningful Works”), a brand marketing agency. In August 2023, we entered into an agreement with Meaningful Works to provide certain services related to brand marketing activities. During 2023, we paid Meaningful Works a total of $206,000 for its services to us.

The information contained in the following report of our Audit Committee is not considered to be “soliciting material,” “filed” or incorporated by reference in any past or future filing by us under the Exchange Act or the Securities Act of 1933, as amended, unless and only to the extent that we specifically incorporate it by reference.

The Audit Committee has reviewed and discussed with our management and BDO USA, P.C. our audited financial statements for the year ended December 31, 2023. The Audit Committee has also discussed with BDO USA, P.C. the matters required to be discussed by applicable requirements of the Public Company Accounting Oversight Board regarding communications between our independent registered public accounting firm and audit committee.

The Audit Committee has received and reviewed the written disclosures and the letter from BDO USA, P.C. required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the audit committee concerning independence, and has discussed with BDO USA, P.C. its independence from us.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2023 for filing with the Securities and Exchange Commission.

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 2023 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:

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.
