### Dear Fellow Stockholder:
On behalf of our board of directors and our senior management team, we are pleased to invite you to attend the 2026 annual meeting of stockholders of Butterfly Network, Inc. to be held at 11:00 a.m., Eastern Time, on Thursday, June 18, 2026. This year's annual meeting will be conducted solely via live audio webcast on the internet. You will be able to attend the annual meeting, vote and submit your questions during the annual meeting by visiting www.virtualshareholdermeeting.com/BFLY2026. You will not be able to attend the annual meeting in person.

Details regarding the meeting, the business to be conducted at the meeting, and information about Butterfly Network, Inc. that you should consider when you vote your shares are described in the accompanying proxy statement.

At the annual meeting, seven persons will be presented to our stockholders for election to our board of directors. In addition, we will ask stockholders to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2026, and to approve, by a non-binding advisory vote, the compensation of our named executive officers, as disclosed in the proxy statement. Our board of directors recommends the approval of each of the three proposals. Such other business will be transacted as may properly come before the annual meeting.

As permitted by the Securities and Exchange Commission's notice and access rules, we have elected to deliver our proxy materials to the majority of our stockholders over the internet. This electronic process gives you fast, convenient access to the materials and reduces the impact on the environment and our printing and mailing costs. On or about April 27, 2026, we will begin sending to our stockholders a Notice of Internet Availability of Proxy Materials (the "Notice") containing instructions on how to access our proxy statement for our 2026 annual meeting of stockholders and our 2025 annual report to stockholders.

We sincerely hope you will join us at our virtual annual meeting. Whether you plan to attend the annual meeting or not, it is important that you cast your vote either in person or by proxy. You may vote over the internet as well as by telephone or by mail. When you have finished reading the proxy statement, you are urged to vote in accordance with the instructions set forth in the proxy statement or the Notice. We encourage you to vote by proxy so that your shares will be represented and voted at the meeting, whether or not you can attend.

Thank you for your ongoing support of Butterfly Network, Inc.

Sincerely,

This proxy statement, including the Letter to Stockholders of Butterfly Network, Inc. (the "Company") contained in this proxy statement, includes "forward-looking statements" within the meaning of the "safe harbor" provisions of the United States Private Securities Litigation Reform Act of 1995. The Company's actual results may differ from its expectations, estimates, and projections and, consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as "expect," "estimate," "project," "budget," "forecast," "anticipate," "intend," "plan," "may," "will," "could," "should," "believes," "predicts," "potential," "continue," and similar expressions (or the negative versions of such words or expressions) are intended to identify such forward-looking statements.

These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from those discussed in the forward-looking statements. Most of these factors are outside the Company's control and are difficult to predict. Factors that may cause such differences include, but are not limited to: the Company's ability to grow and manage growth profitably; the success, cost and timing of the Company's product and service development activities; including the development of additional potential products; the potential attributes and benefits of the Company's products and services; the degree to which the Company's products and services are accepted by healthcare practitioners and patients for their approved uses; the Company's ability to obtain and maintain regulatory approval for its products, and any related restrictions and limitations of any approved product; the Company's ability to identify, in-license or acquire additional technology; the Company's ability to maintain its existing license, manufacture, supply and distribution agreements; manufacturing and supply of the Company's products; the success, cost and timing of the Company's efforts to out-license its intellectual property to third parties; the Company's ability to compete with other companies currently marketing or engaged in the development of products and services that the Company is currently marketing or developing; changes in applicable laws or regulations; the size and growth potential of the markets for the Company's products and services, and its ability to serve those markets, either alone or in partnership with others; the pricing of the Company's products and services and reimbursement for medical procedures conducted using its products and services; the Company's estimates regarding expenses, revenue, capital requirements and needs for additional financing; the Company's financial performance; and other risks and uncertainties indicated from time to time in the Company's most recent Annual Report on Form 10-K or in subsequent filings that it makes with the Securities and Exchange Commission. The Company cautions that the foregoing list of factors is not exclusive. The Company cautions you not to place undue reliance upon any forward-looking statements, which speak only as of the date hereof. The Company does not undertake or accept any obligation or undertake to release publicly any updates or revisions to any forward-looking statements to reflect any change in the Company's expectations or any change in events, conditions or circumstances on which any such statement is based.

This proxy statement, along with the accompanying Notice of 2026 Annual Meeting of Stockholders, contains information about the 2026 annual meeting of stockholders of Butterfly Network, Inc., including any adjournments or postponements of the annual meeting. We are holding the annual meeting at 11:00 a.m., Eastern Time, on Thursday, June 18, 2026. Because hosting a virtual annual meeting enables greater stockholder attendance and participation from any location around the world, improves meeting efficiency and our ability to communicate effectively with our stockholders, and reduces the cost and environmental impact of our annual meeting, this year's annual meeting will be conducted solely via live audio webcast on the internet. You will be able to attend the annual meeting, vote and submit your questions during the annual meeting by visiting www.virtualshareholdermeeting.com/BFLY2026. You will not be able to attend the annual meeting in person.

In this proxy statement, we refer to Butterfly Network, Inc. and its wholly-owned subsidiaries as "Butterfly," the "Company," "we" and "us."

This proxy statement relates to the solicitation of proxies by our board of directors for use at the 2026 annual meeting of stockholders.

On or about April 27, 2026, we will begin sending to our stockholders the Important Notice Regarding the Availability of Proxy Materials containing instructions on how to access our proxy statement for our 2026 annual meeting of stockholders and our 2025 annual report to stockholders.

#### **TABLE OF CONTENTS**

### IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING

### AND VOTING

#### Why is the Company Soliciting My Proxy?
Our board of directors is soliciting your proxy to vote at the 2026 annual meeting of stockholders to be held virtually, on Thursday, June 18, 2026 at 11:00 a.m., Eastern Time, and any adjournments or postponements of the meeting (the "annual meeting"). This proxy statement, along with the accompanying Notice of 2026 Annual Meeting of Stockholders, summarizes the purposes of the meeting and the information you need to know to vote at the annual meeting.

We have made available to you on the internet or have sent you this proxy statement, the Notice of Annual Meeting of Stockholders, the proxy card and a copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 because you owned shares of our Class A common stock or Class B common stock (together, the "common stock") on the record date, April 21, 2026. We will commence distribution of the Important Notice Regarding the Availability of Proxy Materials (the "Notice") and, if applicable, proxy materials to stockholders on or about April 27, 2026.

#### Why Did I Receive a Notice in the Mail Regarding the Internet Availability of Proxy Materials Instead of a Full Set of Proxy Materials?
As permitted by the rules of the U.S. Securities and Exchange Commission (the "SEC"), we may furnish our proxy materials to our stockholders by providing access to such documents on the internet, rather than mailing printed copies of these materials to each stockholder. Most stockholders will not receive printed copies of the proxy materials unless they request them. We believe that this process should expedite stockholders' receipt of proxy materials, lower the costs of the annual meeting and help to conserve natural resources. If you received the Notice by mail or electronically, you will not receive a printed or email copy of the proxy materials, unless you request one by following the instructions included in the Notice. Instead, the Notice instructs you as to how you may access and review all of the proxy materials and submit your proxy on the internet. If you requested a paper copy of the proxy materials, you may authorize the voting of your shares by following the instructions on the proxy card, in addition to the other methods of voting described in this proxy statement.

#### Why Are You Holding a Virtual Annual Meeting?
We are holding a virtual annual meeting to enable us to communicate with our stockholders while supporting the health and well-being of our stockholders and employees. We believe that hosting a virtual annual meeting enables greater stockholder attendance and participation from any location around the world, improves meeting efficiency and our ability to communicate effectively with our stockholders, and reduces the cost and environmental impact of our annual meeting. This year's annual meeting will be held in a virtual meeting format only. We have designed our virtual format to enhance, rather than constrain, stockholder access, participation and communication. For example, the virtual format allows stockholders to communicate with us in advance of, and during, the annual meeting so they can ask questions of our board of directors or management, as time permits.

#### How do I Access the Virtual Annual Meeting?
The live audio webcast of the annual meeting will begin promptly at 11:00 a.m. Eastern Time. Online access to the audio webcast will open 15 minutes prior to the start of the annual meeting to allow time for you to log in and test your device's audio system. The virtual annual meeting is running the most updated version of the applicable software and plugins. You should ensure you have a strong internet connection wherever you intend to participate in the annual meeting. You should also allow plenty of time to log in and ensure that you can hear streaming audio prior to the start of the annual meeting.

Log-in Instructions. To be admitted to the virtual annual meeting, you will need to log in at www.virtualshareholdermeeting.com/BFLY2026 using the 16-digit control number found on the proxy card or voting instruction card previously mailed or made available to stockholders entitled to vote at the annual meeting.

#### Will I Be Able to Ask Questions and Have These Questions Answered During the Virtual Annual Meeting?
Stockholders may submit questions for the annual meeting after logging in. If you wish to submit a question, you may do so by logging into the virtual meeting platform at www.virtualshareholdermeeting.com/BFLY2026, typing your question into the "Ask a Question" field, and clicking "Submit." Please submit any questions before the start time of the meeting.

Appropriate questions related to the business of the annual meeting (the proposals being voted on) will be answered during the annual meeting, as time permits. Additional information regarding the ability of stockholders to ask questions during the annual meeting, related to rules of conduct and other materials for the annual meeting will be available at www.virtualshareholdermeeting.com/BFLY2026.

#### **TABLE OF CONTENTS**

#### What Happens if There Are Technical Difficulties During the Annual Meeting?
Beginning 15 minutes prior to, and during, the annual meeting, we will have technicians ready to assist you with any technical difficulties you may have accessing the virtual annual meeting, voting at the annual meeting or submitting questions at the annual meeting. There will be technical support telephone numbers referenced on the log in page of the virtual annual platform should you require technical assistance and/or experience connectivity issues on the day of the meeting.

#### Who May Vote?
Only stockholders of record at the close of business on April 21, 2026 will be entitled to vote at the annual meeting. As of the close of business on the record date, there were 261,640,906 shares of our common stock outstanding and entitled to vote, consisting of 235,213,969 shares of Class A common stock and 26,426,937 shares of Class B common stock. Our Class A common stock and Class B common stock are our only classes of voting stock.

If on April 21, 2026 your shares of common stock were registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, then you are a stockholder of record.

If on April 21, 2026 your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in "street name" and the Notice is being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the annual meeting. However, since you are not the stockholder of record, you may not vote your shares at the annual meeting unless you request and obtain a valid proxy from your broker or other agent.

You do not need to attend the annual meeting to vote your shares. Shares represented by valid proxies, received in time for the annual meeting and not revoked prior to the annual meeting, will be voted at the annual meeting. For instructions on how to change or revoke your proxy, see "*May I Change or Revoke My Proxy?*" below.

#### How Many Votes Do I Have?
Each share of our Class A common stock that you own entitles you to one vote and each share of our Class B common stock that you own entitles you to 20 votes.

#### How Do I Vote?
Whether you plan to attend the annual meeting or not, we urge you to vote by proxy. All shares represented by valid proxies that we receive through this solicitation, and that are not revoked, will be voted in accordance with your instructions on the proxy card or as instructed via the internet or telephone. You may specify whether your shares should be voted FOR, AGAINST or ABSTAIN for each nominee for director and whether your shares should be voted FOR, AGAINST, or ABSTAIN with respect to each of the other proposals. If you properly submit a proxy without giving specific voting instructions, your shares will be voted in accordance with our board of directors' recommendations as noted below. Voting by proxy will not affect your right to attend the annual meeting.

If your shares are registered directly in your name through our stock transfer agent, Continental Stock Transfer & Trust Company, or you have stock certificates registered in your name, you may vote:

• **By internet or by telephone**. Follow the instructions included in the Notice or, if you received printed materials, in the proxy card to vote over the internet or by telephone.

• **By mail**. If you received a proxy card by mail, you can vote by mail by completing, signing, dating and returning the proxy card as instructed on the card. If you sign the proxy card but do not specify how you want your shares voted, they will be voted in accordance with our board of directors' recommendations as noted below.

**Telephone and Internet voting facilities for stockholders of record will be available 24 hours a day until 11:59 p.m., Eastern Time on June 17, 2026** 

If your shares are held in "street name" (held in the name of a bank, broker or other holder of record), you will receive instructions from the holder of record. You must follow the instructions of the holder of record in order for your shares to be voted. Telephone and internet voting also will be offered to stockholders owning shares through certain banks and brokers.

#### How Does Our Board of Directors Recommend that I Vote on the Proposals?
Our board of directors recommends that you vote as follows:

• "**FOR**" the election of the nominees for director;

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

• "**FOR**" the approval on a non-binding advisory basis of compensation of our NEOs, as disclosed in this proxy statement.

**2026 Proxy Statement**<sub>8</sub>

![](ny20023801x2_footer.jpg)

------

#### **TABLE OF CONTENTS**
If any other matter is presented at the annual meeting, your proxy provides that your shares will be voted by the proxy holder listed in the proxy in accordance with the proxy holder's best judgment. At the time this proxy statement was first made available, we knew of no matters that needed to be acted on at the annual meeting, other than those discussed in this proxy statement.

#### May I Change or Revoke My Proxy?
If you give us your proxy, you may change or revoke it at any time before the annual meeting. You may change or revoke your proxy in any one of the following ways:

• if you received a proxy card, by signing a new proxy card with a date later than your previously delivered proxy and submitting it as instructed above;

• by re-voting by internet or by telephone as instructed above;

• by delivering written notice before the annual meeting to Butterfly Network, Inc.'s Corporate Secretary at Butterfly Network, Inc., 1600 District Avenue, Burlington, Massachusetts 01803, that you have revoked your proxy; or

• by attending the annual meeting and voting at the meeting. Attending the annual meeting will not in and of itself revoke a previously submitted proxy. You must specifically request at the annual meeting that it be revoked.

Your most current vote, whether by telephone, internet or proxy card is the one that will be counted.

#### What if I Receive More Than One Notice or Proxy Card?
You may receive more than one Notice or proxy card if you hold shares of our common stock in more than one account, which may be in registered form or held in street name. Please vote in the manner described above under "How Do I Vote?" for each account to ensure that all of your shares are voted.

#### Will My Shares be Voted if I Do Not Vote?
If your shares are registered in your name or if you have stock certificates, they will not be counted if you do not vote as described above under "*How Do I Vote?*" If your shares are held in street name and you do not provide voting instructions to the bank, broker or other nominee that holds your shares as described above, the bank, broker or other nominee that holds your shares has the discretion to vote uninstructed shares held in street name on "routine" matters. Under stock market rules, a broker lacks discretion to vote shares held in street name on "non-routine" matters in the absence of instructions from the beneficial owner of the stock (called a "broker non-vote"). A "broker non-vote" will occur if your broker cannot vote your shares on a particular matter because it has not received instructions from you and does not have discretionary voting authority on that matter or because your broker chooses not to vote on a matter for which it does have discretionary voting authority. Proposal 2 (the ratification of the appointment of our independent registered public accounting firm) is a routine matter, but Proposals 1 (the election of the nominees for director) and 3 (the approval on a non-binding advisory basis of compensation of our NEOs) are non-routine matters. Therefore, we encourage you to provide voting instructions to your bank, broker or other nominee. This ensures your shares will be voted at the annual meeting and in the manner you desire.

#### What Vote is Required to Approve Each Proposal and How are Votes Counted?

---

| | |
|:---|:---|
| **Proposal 1: Elect Directors** | The nominees for director will be elected by the affirmative vote of a majority of the votes cast for the election of a nominee. For each nominee, you may vote either FOR or AGAINST such nominee, or you may ABSTAIN from voting for one or more nominees. Abstentions will have no effect on the results of this vote. Brokerage firms do not have authority to vote customers' unvoted shares held by the firms in street name for the election of the directors. As a result, any shares not voted by a customer will be treated as a broker non-vote. Such broker non-votes will have no effect on the results of this vote.  |
| **Proposal 2: Ratify Appointment of Independent Registered Public Accounting Firm** | The affirmative vote of a majority of the votes cast for this proposal is required to ratify the appointment of our independent registered public accounting firm. Abstentions will have no effect on the results of this vote. Brokerage firms have authority to vote their customers' unvoted shares held by the firms in street name on this proposal. If a broker does not exercise this authority, such broker non-votes will have no effect on the results of this vote. We are not required to obtain the approval of our stockholders to select our independent registered public accounting firm. However, if our stockholders do not ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026, our audit committee of our board of directors will reconsider its selection.  |

Abstentions will have no effect on the results of this vote. Brokerage firms do not have authority to vote customers' unvoted shares held by the firms in street name on this proposal.

Although the advisory vote is non-binding, our compensation committee and our board of directors will review the voting results and take them into consideration when making future decisions regarding executive compensation. |

We will then reimburse them for their expenses.

#### What Constitutes a Quorum for the Annual Meeting?
The presence of the holders of a majority in voting power of our common stock issued and outstanding and entitled to vote at the annual meeting, in person or represented by proxy, will constitute a quorum at the annual meeting.

#### Householding of Annual Disclosure Documents
Some brokers or other nominee record holders may be sending you a single set of our proxy materials if multiple Butterfly Network, Inc. stockholders live in your household. This practice, which has been approved by the SEC, is called "householding." Once you receive notice from your broker or other nominee record holder that it will be "householding" our proxy materials, the practice will continue until you are otherwise notified or until you notify them that you no longer want to participate in the practice. Stockholders who participate in householding will continue to have access to and utilize separate proxy voting instructions.

We will promptly deliver a separate copy of our Notice or, if applicable, our proxy materials to you if you write or call our Corporate Secretary at: Butterfly Network, Inc., 1600 District Avenue, Burlington, Massachusetts 01803 or (781) 557-4800.

#### Board Skills Table
Our director nominees are highly-skilled individuals with diverse qualifications, enabling the board of directors to advise the Company on a variety of matters. Below are certain qualifications, skills and experiences of our director nominees that contribute to the board of directors' effectiveness as a whole.

![](ny20068165x1_skills.jpg)

<sup>(1)</sup> Effective immediately following the annual meeting, Mr. Robbins will serve as chair of the compensation committee, subject to his election to our board of directors at the annual meeting.

<sup>(2)</sup> Ms. Phanstiel is chair of the audit committee.

<sup>(3)</sup> Dr. Schwartz is chair of the nominating and governance committee.

<sup>(4)</sup> Dr. Edelman is chair of the technology committee.

#### Role of Board in Risk Oversight
The board of directors have extensive involvement in the oversight of risk management related to the Company and its business and accomplishes this oversight through the regular reporting to the board of directors by the audit committee. The audit committee periodically reviews the Company's accounting, reporting and financial practices, including the integrity of its financial statements, the surveillance of administrative and financial controls and its compliance with legal and regulatory requirements. Through its regular meetings with management, including the finance, legal, internal audit and information technology functions, the audit committee reviews and discusses all significant areas of our business and summarizes for the board of directors areas of risk and the appropriate mitigating factors. In addition, the board of directors receives periodic detailed operating performance reviews from management.

#### **TABLE OF CONTENTS**
The audit committee oversees the Company's cybersecurity controls. The Company uses, stores and processes data for and about our customers, employees, partners and suppliers. The Company has implemented a cybersecurity risk management program that is designed to identify, assess, and mitigate risks from cybersecurity threats to this data and the Company's systems.

#### Controlled Company Exemption
Jonathan M. Rothberg, Ph.D. beneficially owns a majority of the voting power of all outstanding shares of the Company's common stock. As a result, we are a "controlled company" within the meaning of the corporate governance standards of the New York Stock Exchange ("NYSE"). Under these corporate governance standards, a company of which more than 50% of the voting power for the election of directors is held by an individual, group or another company is a "controlled company" and may elect not to comply with certain corporate governance standards, including the requirements (1) that a majority of its board of directors consist of independent directors, (2) that its board of directors have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities and (3) that its board of directors have a nominating and corporate governance committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities. As a result, we may utilize one or more of these exemptions, and you may not have the same protections afforded to stockholders of companies that are subject to all of these corporate governance requirements. However, we do not currently utilize any of the foregoing exemptions.

If we cease to be a "controlled company" and our shares continue to be listed on the NYSE, we will be required to comply with these standards and, depending on the board's independence determination with respect to its then-current directors, we may be required to add additional directors to our board in order to achieve such compliance within the applicable transition periods. Pursuant to our Third Amended and Restated Certificate of Incorporation, as amended, all of our shares of Class B common stock, which are currently held by Dr. Rothberg, will automatically convert into shares of Class A common stock effective February 12, 2028. Therefore, we will cease to be a "controlled company" on or before February 12, 2028.

#### Composition of the Board of Directors
Our business and affairs are managed under the direction of our board of directors. Our board of directors is declassified, and the directors are elected annually.

#### Independence of the Board of Directors
NYSE rules generally require that independent directors comprise a majority of a listed company's board of directors. As a controlled company, we are largely exempt from such requirements. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, we have determined that Larry Robbins, Dawn Carfora, Elazer Edelman, M.D., Ph.D., Caroll H. Neubauer, S. Louise Phanstiel and Erica Schwartz, M.D., J.D., M.P.H., representing five of the Company's seven current directors and one director nominee, are "independent" as that term is defined under the applicable rules and regulations of the SEC and the listing requirements and rules of the NYSE.

#### Board Committees
The standing committees of our board of directors consist of an audit committee, a compensation committee, a nominating and corporate governance committee and a technology committee. The board of directors may from time to time establish other committees.

Our Chief Executive Officer and other executive officers regularly report to the non-executive directors and the audit, the compensation and the nominating and corporate governance committees to ensure effective and efficient oversight of our activities and to assist in proper risk management and the ongoing evaluation of management controls. We believe that the leadership structure of the board of directors will provide appropriate risk oversight of our activities given the controlling interests held by Jonathan M. Rothberg, Ph.D.

*Meeting Attendance. During the fiscal year ended December 31, 2025, there were seven meetings of our board of directors, and the committees of the board of directors described below met a total of twenty times. No director attended fewer than 75% of the total number of meetings of the board of directors and of committees of the board of directors on which such director served during the fiscal year ended December 31, 2025. The board of directors has adopted a policy under which each member of the board of directors makes reasonable best efforts to, but is not required to, attend each annual meeting of our stockholders. None of our directors then serving as directors attended our 2025 annual meeting of stockholders.*

#### **TABLE OF CONTENTS**

### Audit Committee
Our audit committee met seven times during the fiscal year ended December 31, 2025. Our audit committee consists of S. Louise Phanstiel, who serves as the Chairperson, Dawn Carfora and Larry Robbins. Effective as of immediately following the annual meeting, our audit committee will consist of Ms. Phanstiel as Chairperson and each of Mr. Robbins and Dr. Schwartz as members, in each case subject to such member's election to our board of directors at the annual meeting. Each member of the audit committee qualifies as an independent director under the NYSE corporate governance standards and the independence requirements of Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The board of directors has determined that Ms. Phanstiel qualifies as an "audit committee financial expert" as such term is defined in Item 407(d)(5) of Regulation S-K and possesses financial sophistication, as defined under the rules of the NYSE.

The purpose of the audit committee is to prepare the audit committee report required by the SEC to be included in our proxy statement, assist the board of directors in overseeing and monitoring (1) the quality and integrity of the financial statements, (2) compliance with legal and regulatory requirements, (3) our independent registered public accounting firm's qualifications and independence, (4) the performance of our internal audit function (5) the performance of our independent registered public accounting firm, and oversee the Company's cybersecurity risk management program.

The board of directors has adopted a written charter for the audit committee, which is available on the Company's website at www.butterflynetwork.com under About Us - Investors - Governance - Corporate Governance.

### Compensation Committee
Our compensation committee met six times during the fiscal year ended December 31, 2025. Our compensation committee is comprised of all independent directors and consists of Dawn Carfora, who serves as the Chairperson, S. Louise Phanstiel and Larry Robbins. Effective as of immediately following the annual meeting, our compensation committee will consist of Mr. Robbins as Chairperson and each of Mr. Neubauer and Ms. Phanstiel as members, in each case subject to such member's election to our board of directors at the annual meeting.

The purpose of the compensation committee is to assist the board of directors in discharging its responsibilities relating to (1) setting our compensation program and compensation of our executive officers and directors (aside from our Chief Executive Officer), (2) monitoring our incentive and equity-based compensation plans, (3) preparing the compensation committee report required to be included in our proxy statement under the rules and regulations of the SEC, and (4) overseeing matters relating to human capital management, including diversity and inclusion and internal pay equity.

Each year, typically during the first calendar quarter, we evaluate each executive officer's performance for the prior year. In connection with the annual review cycle, the Chief Executive Officer meets with our executive officers to discuss our accomplishments and the individual's performance and contributions during the prior year. The Chief Executive Officer also evaluates company performance against corporate goals. This process leads to a recommendation by the Chief Executive Officer to the compensation committee with respect to each executive officer, other than himself, as to:

• the achievement of corporate goals and individual performance;

• the level of contributions made to the general management and leadership of the Company;

• the appropriateness of salary increases;

• the amount of bonuses to be paid, if any; and

• whether or not stock option, RSU and/or other equity awards should be made.

These recommendations are reviewed and taken into account by the compensation committee, together with the compensation committee's evaluation of the Chief Executive Officer's performance and contributions. The compensation committee then approves the compensation of our Section 16(b) officers, and makes a recommendation on the compensation of our Chief Executive Officer and Chairperson of the board of directors to the full board of directors, which then approves the compensation of our Chief Executive Officer. Mr. DeVivo, our Chief Executive Officer and Chairperson of the board of directors, is not present when the compensation committee or the board of directors discusses and makes decisions about his compensation. The compensation committee grants RSUs and/or other equity awards to our Section 16(b) officers.

In 2025, the compensation committee engaged Pay Governance as a compensation consultant to evaluate executive compensation, discuss general compensation trends, provide competitive market practice data, and assist in the design and implementation of certain elements of the executive compensation program.

Pay Governance has served as our compensation committee's sole independent compensation consultant since 2024. Pay Governance reports directly to the compensation committee, and the compensation committee has the sole authority to hire, fire and direct the work of Pay Governance. As part of its engagement, Pay Governance is regularly requested by the

compensation committee to update our comparative peer group and perform an analysis of executive compensation as relates to base salary, target annual cash incentives and long-term equity incentives. Pay Governance provides recommendations for public company executive compensation, based on its review of proxy statement data, survey data, current industry trends, existing employment arrangements, appropriate dilution and overhang and other factors specifically related to us, increases to the level of base salary of certain executive officers, setting target bonus opportunities for the annual performance-based cash incentive plan, and equity awards to certain executive officers. Our compensation committee and, with respect to our Chief Executive Officer, our board of directors, considered these recommendations, along with the Company's and the individual's overall performance and the unique circumstances associated with any individual executive, in determining these compensation changes, which were made to ensure better alignment with market data and in consideration of internal pay equity.

Although our board of directors and compensation committee consider the advice and recommendations of Pay Governance or any other independent compensation consultant that our compensation committee may engage as to our executive or director compensation, our board of directors and compensation committee ultimately make their own decisions about these matters.

Pay Governance did not provide any services to us or our compensation committee other than as described above in connection with our executive and director compensation for 2025, although we may engage Pay Governance or another consultant to provide services for us in connection with executive and director compensation in the future. The compensation committee assessed the independence of Pay Governance pursuant to SEC rules and concluded that the work of Pay Governance for the compensation committee does not raise any conflict of interest.

Our board of directors has adopted a written charter for the compensation committee, which is available on the Company's website at www.butterflynetwork.com under About Us - Investors - Governance - Corporate Governance.

### Nominating and Corporate Governance Committee
Our nominating and corporate governance committee met three times during the fiscal year ended December 31, 2025. Our nominating and corporate governance committee is comprised of all independent directors and consists of Erica Schwartz, M.D., J.D., M.P.H., who serves as the Chairperson, Elazer Edelman and Larry Robbins. Effective as of immediately following the annual meeting, our nominating and corporate governance committee will consist of Dr. Schwartz as Chairperson and each of Dr. Edelman and Ms. Phanstiel as members, in each case subject to such member's election to our board of directors at the annual meeting.

The purpose of the nominating and corporate governance committee is to assist the board of directors in discharging its responsibilities relating to (1) identifying individuals qualified to become new board of directors members, consistent with criteria approved by the board of directors, (2) reviewing the qualifications of incumbent directors to determine whether to recommend them for reelection and selecting, or recommending that the board of directors select, the director nominees for the next annual meeting of stockholders, (3) identifying board of directors members qualified to fill vacancies on any board of directors committee and recommending that the board of directors appoint the identified member or members to the applicable committee, (4) reviewing and recommending to the board of directors corporate governance principles applicable to the Company, (5) overseeing the evaluation of the board of directors and management and (6) handling such other matters that are specifically delegated to the committee by the board of directors from time to time.

Generally, our nominating and corporate governance committee considers candidates recommended by stockholders as well as from other sources such as other directors or officers, third party search firms or other appropriate sources. Once identified, the nominating and corporate governance committee will evaluate a candidate's qualifications in accordance with our corporate governance guidelines. Threshold criteria include: independence, experience, skills, expertise, diversity, personal and professional integrity, character, business judgment, time availability in light of other commitments, dedication and conflicts of interest. Our nominating and corporate governance committee has not adopted a formal diversity policy in connection with the consideration of director nominations or the selection of nominees. However, the nominating and corporate governance committee will consider issues of diversity among its members in identifying and considering nominees for director, and strive where appropriate to achieve a diverse balance of backgrounds, perspectives, experience, age, gender, ethnicity and country of citizenship on our board of directors and its committees. Mr. Neubauer, our director nominee who is not an incumbent director, was recommended to our nominating and corporate governance committee by the chief executive officer.

#### **TABLE OF CONTENTS**

### Compensation Committee Interlocks and Insider Participation
Our compensation committee has three members: Dawn Carfora, who serves as the chairperson, S. Louise Phanstiel and Larry Robbins. In 2025, none of our executive officers served on the board of directors or compensation committee of any entity that had one or more executive officers serving as a member of our board of directors or compensation committee. There are no family relationships between or among the members of our board of directors or executive officers.

### Board Leadership Structure and Role on Risk Oversight
Our board of directors recognizes the time, effort and energy that the Chief Executive Officer must devote to his position in the current business environment, as well as the commitment required to serve as our Chairman, particularly as the board of directors' oversight responsibilities continue to grow. In addition, Mr. Robbins currently serves as the lead independent director of the board. Our board of directors believes its administration of its risk oversight function has not affected its leadership structure.

Our board of directors believes that this structure is enhanced by the independent leadership provided by our lead independent director. The lead independent director's responsibilities include, but are not limited to, the following: (i) presides over all meetings of the board of directors at which the Chairman is not present, including executive sessions of the non-management directors; (ii) serves as a liaison between the Chairman and Chief Executive Officer, and non-management directors to increase efficiency and streamline communications and apprise non-management directors of matters discussed; (iii) in consultation with the Chairman and Chief Executive Officer, is responsible for the meeting agendas for the board of directors, and reviews the meeting schedules to assure that there is sufficient time for discussion of all agenda items; (iv) advises the Chief Executive Officer of the board of director's informational needs following consultation with non-management directors, has the authority to approve the materials to be delivered to the directors in advance of regular meetings of the board of directors, and provides feedback regarding the quality, quantity, and timeliness of those materials; (v) has the authority to call meetings of the independent directors; (vi) communicates with the Chief Executive Officer about decisions reached, suggestions and views expressed by non-management directors in executive sessions or outside of meetings of the board of directors (except that the chairman of the compensation committee leads the discussion of the Chief Executive Officer's performance and communicates the Board's evaluation of that performance to the Chief Executive Officer); (vii) if requested by major stockholders, is available when appropriate, for consultation and direct communication in compliance with the Company's policies and procedures; and (viii) performs such other duties as requested by independent directors.

Currently, our Chief Executive Officer is also our Chairman. Our board of directors believes that, at this time, having a combined Chief Executive Officer and Chairman is the appropriate leadership structure for the Company. In making this determination, the board of directors considered, among other matters, Mr. DeVivo's management of our business on a day-to-day basis coupled with his direct involvement in our business operations, and believes that Mr. DeVivo is highly qualified to act as both Chairman and Chief Executive Officer due to his experience, knowledge, and personality. Among the benefits of a combined Chief Executive Officer/Chairman considered by the board of directors is that such structure promotes clearer leadership and direction for the Company and allows for a single, focused chain of command to execute our strategic initiatives and business plans.

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. Our board of directors is actively involved in oversight of risks that could affect the Company. This oversight is conducted primarily by our full board of directors, which has responsibility for general oversight of risks. As part of its oversight, our board of directors receives reports by each committee chair regarding the committee's considerations and actions. In particular, the audit committee is responsible for discussing the adequacy of our risk management activities with management and our independent registered public accounting firm. The audit committee's primary emphasis is financial risk, including our internal control over financial reporting, and it also oversees our management of exposure to certain financial risks through its periodic review of our investment policy and the allocation of our investment portfolio. In addition, the compensation committee is responsible for considering whether our compensation programs and practices are reasonably likely to have a material adverse effect on us.

At each of its meetings, the board of directors receives business updates from various members of management. These updates may identify matters that have emerged within that member of management's scope of responsibility that involve operational, financial, legal or regulatory risks and, in these cases, the board of directors provides guidance to management. Our board of directors believes that full and open communication between management and the board of directors is essential for effective risk management and oversight.

### Insider Trading Policy
We have adopted an insider trading policy governing the purchase, sale and other transactions in our securities by our directors, officers, employees and certain other covered persons.

The policy prohibits our directors, officers, employees and certain other covered persons from illegally trading in Company securities and related derivative securities while aware of material non-public information about the Company or its securities. Additionally, certain individuals are prohibited from trading securities during various times throughout the year, and certain individuals must receive preclearance from our Chief Financial Officer or his designee prior to trading. Our insider trading policy is filed as an exhibit to our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

### Prohibition on Hedging and Pledging
Our insider trading policy also prohibits members of the board of directors, NEOs, and all other subject personnel from purchasing financial instruments designed to hedge the economic risk of owning our securities (or entering any transaction that has the same economic effect), and prohibits certain persons, including members of the board of directors and the NEOs, from pledging our securities.

### Code of Conduct and Ethics

Generally, stockholders and other constituents who have questions or concerns should contact our Investor Relations group at investors@butterflynetwork.com.

Communications will be distributed to the board of directors, or to any individual director or directors as appropriate, depending on the facts and circumstances outlined in the communications. Items that are unrelated to the duties and responsibilities of the board of directors may be excluded, such as: junk mail and mass mailings; resumes and other forms of job inquiries; surveys; and solicitations or advertisements. In addition, any material that is unduly hostile, threatening, or illegal in nature may be excluded, provided that any communication that is filtered out will be made available to any outside director upon request.

<sup>(1)</sup> The amounts in this column reflect the aggregate grant date fair value of stock awards granted during 2025 and 2024, respectively, computed in accordance with Accounting Standards Codification ("ASC") Topic 718, Compensation-Stock Compensation ("Topic 718"). Such grant date fair values do not take into account any estimated forfeitures. Details as to the assumptions used to calculate the fair value of the stock awards are included in Note 11 "Stock-Based Compensation" to our consolidated audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The grant date fair value of each time-based RSU award is measured based on the closing price of our Class A common stock on the grant date. For performance-based RSU awards granted on December 8, 2025 and September 3, 2024 to Mr. Doherty and Mr. Cashman, respectively, the vesting conditions relating to each such awards are considered market conditions and not financial performance conditions. Accordingly, there is no grant date fair value below or in excess of the amounts reflected in the table above for Mr. Doherty and Mr. Cashman that could be calculated and disclosed based on achievement of the underlying market condition. The grant date fair value of such performance-based awards with a market condition granted to Mr. Doherty and Mr. Cashman, measured utilizing a Monte Carlo simulation as of the date of grant, was $1,284,798 and $1,026,667, respectively.

### Narrative to 2025 Summary Compensation Table

### Elements of Compensation

### Base Salary
Base salaries are a fixed amount paid to each executive for performing his or her normal duties and responsibilities. We determine the amount based on the executive's overall performance, level of responsibility, and comparison to market data. Based on these criteria, in February 2025, our board of directors approved base salaries of $901,000, $530,000 and $618,000 for Joseph DeVivo, Steven Cashman and Heather Getz, respectively, for 2025. Ms. Getz resigned from her role as Chief Financial & Operations Officer on August 1, 2025 and departed on August 15, 2025.

Our board of directors, upon recommendation of our compensation committee approved an annual base salary of $530,000 for John Doherty upon his commencement of employment with us on December 8, 2025.

Effective January 1, 2026, our board of directors, upon recommendation of the compensation committee, approved a salary increase for Mr. DeVivo to $928,000. Also effective January 1, 2026, our compensation committee approved a salary increase for Mr. Cashman to $530,250.

### Annual Bonus Plan
Our annual bonus plan for 2025 was a cash program that rewards employees for achieving critical business and financial goals that are key indicators of ongoing operational performance and support our ongoing business strategy. The compensation committee reviews our target annual bonus opportunities each year to ensure they are competitive. The target annual incentive opportunity as a percent of annual base salary for each of our NEOs in 2025 was as follows:

<sup>(1)</sup> Mr. Doherty commenced employment with the Company on December 8, 2025 and was not eligible for the Company's 2025 annual bonus plan.

The compensation committee undertook a rigorous and holistic review of performance when determining its recommendation as to final bonus payouts for the NEOs. The goals included the Company's 2025 revenue achievement compared to internal targets, the Company's adjusted EBITDA, and execution against various operational goals, such as the successful launch of the Company's Compass 2.0 (a revamped version of the Company's enterprise software offering), signing two additional enterprise customers (defined as a customer that integrates 500 probes to Compass), and moving the Company's P5 generation chip into production.

### Policies and Practices Related to the Grant of Equity Awards Close in Time to the Release of Material Nonpublic Information
Since mid-2022, we have exclusively granted RSUs and PSUs under our equity incentive program. Accordingly, we do not have a formal policy related to the timing of option awards in relation to the release of material nonpublic information. The compensation committee and our board of directors do not take material nonpublic information into account when determining the timing or terms of awards, and we have not timed the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation.

### Employment Agreements and Severance Benefits
We have entered into employment agreements or offer letters with each of our executive officers, including our NEOs, which set forth their basic terms of at-will employment and establish the individual's initial base salary, eligibility to participate in the annual bonus plan and receive equity awards, and eligibility to participate in standard employee benefits. Furthermore, some of these agreements or offer letters also provide for certain benefits under qualifying terminations. Each of these agreements are described below.

#### Joseph DeVivo
We entered into an employment agreement with Mr. DeVivo, as our President and Chief Executive Officer, to begin employment on April 24, 2023, which was subsequently amended effective June 5, 2023 and further amended effective January 1, 2024 (such agreement, as amended, the "DeVivo Employment Agreement"). Pursuant to the DeVivo Employment Agreement, Mr. DeVivo is eligible to receive an annual discretionary bonus with a target of 125% of his base salary. Pursuant to the DeVivo Employment Agreement, in 2023, Mr. DeVivo was granted (i) 2,400,000 RSUs (the "DeVivo RSUs"), with one-third of such RSUs vesting on the grant date and the remainder of such RSUs vesting on a pro rata annual basis over the next two years and (ii) 1,600,000 PSUs (the "DeVivo Performance RSUs" and collectively with the DeVivo RSUs, the "Initial Equity Grants"), with the DeVivo Performance RSUs vesting as follows: (i) one-third vested upon the achievement of a price for the Class A common stock equal to or exceeding $3.00 per share, (ii) one-third shall vest upon the achievement of a price for the Company's Class A common stock equal to or exceeding $4.50 per share and (iii) one-third shall vest upon the achievement of a price for the Company's Class A common stock equal to or exceeding $6.00 per share. In each case, the closing stock price for 20 consecutive trading days must equal or exceed the share price targets, and provided such share price is achieved prior to the fifth anniversary following the grant date of such DeVivo Performance RSU. Mr. DeVivo must continue to have a service relationship with the Company on the applicable vesting dates to vest in any shares in the Initial Equity Grants.

If Mr. DeVivo's employment is terminated by the Company without cause or by Mr. DeVivo for good reason outside of the change of control period (as defined in the DeVivo Employment Agreement), subject to Mr. DeVivo's execution of and non-revocation of a separation agreement, Mr. DeVivo will be entitled to receive: (i) a cash payment in an amount equal to one times the sum of (A) Mr. DeVivo's then current base salary, plus (B) Mr. DeVivo's target bonus for the then current year, and (C) an additional $100,000, to be paid in substantially equal installments for 12 months following such termination, (ii) subject to Mr. DeVivo's copayment of premium amounts at the applicable active employees' rate and proper election to continue Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA") health coverage, payment of the portion of the premiums equal to the amount that we would have paid to provide health insurance to Mr. DeVivo had he remained employed with us for up 12 months following such termination, and (iii) partial acceleration of vesting of any unvested time-based equity awards equal to the portion of the award that would have vested had Mr. DeVivo remained employed by the Company for the 12-month period following such termination.

The DeVivo Employment Agreement also requires Mr. DeVivo to enter into a non-competition, confidentiality and intellectual property agreement with the Company.

### Executive Severance Plan
Our Executive Severance Plan (as defined below) ensures alignment with market data and the benefits offered by the companies in our peer group, and helps to attract, retain and motivate superior executive talent.

In addition, all outstanding unvested equity awards held by an NEO who is a participant in the Executive Severance Plan will become fully vested upon termination without cause or for good reason within 12 months following a change of control. We have not provided any excise tax gross-ups to any of our NEOs in the event of a change of control. Pursuant to the terms of the DeVivo Employment Agreement, Mr. DeVivo is not eligible to participate in the Executive Severance Plan.

### Additional Narrative Disclosure

### 401(k) Plan
We maintain a tax-qualified retirement plan that provides eligible U.S. employees, including our NEOs, with an opportunity to save for retirement on a tax-advantaged basis. All participants' interests in their contributions are 100% vested when contributed. Contributions are allocated to each participant's individual account and are then invested in selected investment alternatives according to the participants' directions. The retirement plan is intended to qualify under Section 401(a) of the Code. We match 100% percent of employee contributions, up to 2% percent of each employee's compensation (as defined in the plan).

### Health and Welfare Benefits
All of our full-time employees, including our executive officers, are eligible to participate in certain medical, disability and life insurance benefit programs offered by us.

### Other Benefits
Our NEOs who currently serve as employees (and some other employees) are also entitled to additional benefits, including reimbursement of certain housing and commuting expenses, including reimbursement relocation expenses.

### Nonqualified Deferred Compensation
We do not have any nonqualified defined contribution plans or other deferred compensation plans.

### Employee Stock Purchase Plan
Subject to certain restrictions outlined in the Company's Employee Stock Purchase Plan (the "ESPP"), all employees and NEOs who currently serve as employees are eligible to participate in the Company's ESPP. The ESPP allows participating employees to enroll in a two-year offering period split into four purchase periods. Each purchase period lasts six months and new offering periods begin twice a year on January 1 and July 1. Participating employees must confirm their elections for payroll deduction prior to the start of the offering period and the Company then deducts that portion from each of the employee's paychecks during the offering period, using the funds to purchase shares of Class A common stock at a discounted rate at the conclusion of the offering period.

### Executive Severance Plan
On May 3, 2021, the compensation committee of the board of directors adopted the Butterfly Network, Inc. Executive Severance Plan, which was subsequently amended on November 10, 2021 and further amended by our board of directors on June 30, 2025 (the "Executive Severance Plan"). Eligible participants in the Executive Severance Plan include our executives having the title of senior vice president or executive vice president, except that, pursuant to the terms of the DeVivo Employment Agreement, Mr. DeVivo is not eligible to participate in the Executive Severance Plan.

Under the Executive Severance Plan, if we terminate a participant's employment without cause (as defined in the Executive Severance Plan) or a participant resigns for good reason (as defined in the Executive Severance Plan) at any time other than during the 12 month period following a change in control (as such term is defined in the Executive Severance Plan) (the "Change in Control Period"), then the participant is eligible to receive the following benefits:

• Severance payable in the form of salary continuation. The severance amount is equal to participant's then-current base salary times a multiplier determined based on the participant's title or role with us. The multiplier for Mr. Doherty and Mr. Cashman (executive vice president) is 1.0.

• We will pay for company contribution for continuation coverage under COBRA, during the severance period.

Under the Executive Severance Plan, if we terminate a participant's employment without cause or participant resigns for good reason, during the Change in Control Period, then the participant is eligible to receive the following benefits:

• Severance payable in a single lump sum. The severance amount is equal to participant's then-current base salary and then-current target annual bonus opportunity, times a change in control multiplier of 1.0.

• We will pay for company contribution for continuation coverage under COBRA during the severance period.

• Any outstanding unvested equity awards held by the participant under our then-current outstanding equity incentive plan(s) will become fully vested on the date the termination of such participant's employment becomes effective.

A participant's rights to any severance benefits under the Executive Severance Plan are conditioned upon the participant executing and not revoking a valid separation and general release of claims agreement in a form provided by us.

The Executive Severance Plan also includes a modified 280G cutback, which provides that to the extent Total Payments (as defined in the Executive Severance Plan) would be subject to the excise tax imposed under Section 4999 of the Code, then the Total Payments shall be reduced (but not below zero) so that the maximum amount of Total Payments (after reduction) shall be one dollar less than the amount which would cause the Total Payments to be subject to the excise tax imposed by Section 4999 of the Code, but only if such reduced amount would result in the participant receiving a net after tax amount that exceeds the net after tax amount the participant would receive if the Total Payments were not reduced and were instead subject to the excise tax imposed by Section 4999 of the Code.

The term "change in control" under the Executive Severance Plan means:

&nbsp;&nbsp;&nbsp;&nbsp;(i) any person or group of persons (other than us or our affiliates) becomes the owner, directly or indirectly, of our securities representing more than 50% of the combined voting power or the fair market value of our then outstanding voting securities (the "Outstanding Company Voting Securities") (but excluding any bona fide financing event in which securities are acquired directly from us); or

&nbsp;&nbsp;&nbsp;&nbsp;(ii) the consummation of a merger or consolidation of us with any other corporation, other than a merger or consolidation (i) that results in the Outstanding Company Voting Securities immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least 50% of the combined voting power of the Outstanding Company Voting Securities (or such surviving entity or, if we or the entity surviving such merger is then a subsidiary, the ultimate parent thereof) outstanding immediately after such merger or consolidation, or (ii) immediately following which the individuals who comprise the board of directors immediately prior thereto constitute at least a majority of the board of directors of the entity surviving such merger or consolidation or, if we or the entity surviving such merger is then a subsidiary, the ultimate parent thereof; or

&nbsp;&nbsp;&nbsp;&nbsp;(iii) the sale or disposition by us of all or substantially all of our assets, other than (i) a sale or disposition by us of all or substantially all of our assets to an entity, at least 50% of the combined voting power of the voting securities of which are owned directly or indirectly by our stockholders following the completion of such transaction in substantially the same proportions as their ownership of us immediately prior to such sale or (ii) a sale or disposition of all or substantially all of our assets immediately following which the individuals who comprise the board of directors immediately prior thereto constitute at least a majority of the board of directors of the entity to which such assets are sold or disposed or, if such entity is a subsidiary, the ultimate parent thereof;

&nbsp;&nbsp;&nbsp;&nbsp;(iv) provided that with respect to Sections (i), (ii) and (iii) above, a transaction or series of integrated transactions will not be deemed a Change in Control (A) unless the transaction qualifies as a change in control within the meaning of Section 409A

of the Code, or (B) if following the conclusion of the transaction or series of integrated transactions, the holders of our Class B common stock immediately prior to such transaction or series of transactions continue to have substantially the same proportionate voting power in an entity which owns all or substantially all of our assets immediately following such transaction or series of transactions.

### Compensation Recovery Policy (Clawback Policy)
Effective October 2, 2023, we adopted a compensation recovery policy (the "Clawback Policy") in compliance with the requirements of the Dodd-Frank Act, final SEC rules and applicable New York Stock Exchange listing standards (the "final clawback rules"), which covers our current and former executive officers, including all of our NEOs, and any other person designated by our compensation committee or board of directors as being subject to the Clawback Policy. Under the Clawback Policy, in the event that we are required to prepare a restatement of our previously issued financial statements due to our material noncompliance with any financial reporting requirement under securities laws, we are required to recover (subject to certain limited exceptions described in the Clawback Policy and permitted under the final clawback rules) any cash or equity incentive-based compensation received by any current or former executive officer after the effective date of the Clawback Policy and in the three completed fiscal years prior to the date we are required to restate our financial statements that is in excess of the amount that would have been received based on the restated financial statements.

### Pay Versus Performance
As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, we are providing information about the relationship between executive compensation actually paid to our PEO and the other NEOs (as calculated in accordance with Item 402(v) of Regulation S-K) and certain financial performance measures.

The following table shows the total compensation for our NEOs for the past three fiscal years as set forth in the Summary Compensation Table, the compensation actually paid ("CAP") to our first PEO (Joseph DeVivo, Chief Executive Officer from April 24, 2023 to the present, "PEO1"), our second PEO (Jonathan Rothberg, Interim Chief Executive Officer from December 31, 2022 to April 24, 2023, "PEO2") and, on an average basis, our other NEOs (in each case, as determined under SEC rules), our total shareholder return ("TSR") and our net income.

<sup>(1)</sup> For 2025, Mr. DeVivo served as our only PEO, and each of Mr. Cashman, Mr. Doherty and Ms. Getz served as our non-PEO NEOs. For 2024, Mr. DeVivo served as our only PEO, and Ms. Getz and Mr. Cashman served as our non-PEO NEOs. For 2023, Mr. DeVivo and Dr. Rothberg each served as our PEO during part of the year, and Ms. Getz and Mr. Stoica served as our non-PEO NEOs. 

<sup>(2)</sup> The dollar amounts reported in column (b) are the amounts of total compensation reported for our PEOs for each corresponding year in the "Total" column of the Summary Compensation Table. 

<sup>(3)</sup> The dollar amounts reported in columns (c) and (e) represent the amount of CAP as computed in accordance with SEC rules. CAP does not necessarily represent cash and/or equity value transferred to the applicable NEO without restriction, but rather is a value calculated under applicable SEC rules. We do not have a defined benefit plan so no adjustment for pension benefits is included in the table below. Similarly, no adjustment is made for dividends as dividends are factored into the fair value of the award. The following table details these adjustments:

---

<sup>(1)</sup> Effective April 2025.

These fees are payable in arrears in quarterly installments as soon as practicable following the last business day of each fiscal quarter, provided that, following the director's first election or appointment to the board of directors, such director's cash compensation will be prorated during the first fiscal quarter in which he or she was initially appointed or elected for the number of days during which he or she provides service. If a director dies, resigns or is removed during any quarter, he or she will be entitled to a cash payment prorated through his or her last day of service. Non-employee directors are also reimbursed for reasonable out-of-pocket business expenses incurred in connection with attending meetings of the board of directors and any committee of the board on which they serve and in connection with other business related to the board of directors. Directors may also be reimbursed for reasonable out-of-pocket business expenses in accordance with our travel and other expense policies, as may be in effect from time to time.

In addition, we grant to new non-employee directors upon their initial election to our board of directors a number of RSUs, (each RSU relating to one share of our Class A common stock), having an aggregate fair market value equal to $300,000, determined by dividing (A) $300,000 by (B) the closing price of our Class A common stock on the NYSE on the date of the grant (rounded down to the nearest whole share), on the first business day after the date that the non-employee director is first appointed or elected to the board of directors. Each of these grants shall vest in equal annual installments over three years from the date of the grant, subject to the non-employee director's continued service as a director on the applicable vesting dates.

Further, in connection with each of our annual meetings of stockholders, each non-employee director automatically receives an option to purchase shares of our Class A common stock or RSUs having an aggregate grant date fair value of $185,000 (increased from $150,000 effective April 2025), valued according to Topic 718 (rounded down to the nearest whole share), each year on the first business day after our annual meeting of stockholders (or the first business day of the third fiscal quarter of such year if there has been no annual meeting of stockholders held by such date). Options have a term of 10 years from the grant date of the award. The award vests at the end of the period beginning on the date of each regular annual meeting of stockholders (or the first business day of the third fiscal quarter, as applicable) and ending on the date of the next regular annual meeting of stockholders, subject to the non-employee director's continued service as a director through the applicable vesting dates.

<sup>(1)</sup> These plans consist of our 2012 Employee, Director and Consultant Equity Incentive Plan, (the "2012 Plan"), our Amended and Restated 2020 Equity Incentive Plan, as amended, (the "2020 Plan"), and our ESPP.

<sup>(2)</sup> Consists of (i) 4,115,855 shares to be issued upon exercise of outstanding options and vesting of outstanding RSUs under the 2012 Plan and (ii) 22,973,935 shares to be issued upon exercise of outstanding options and vesting of outstanding RSUs under the 2020 Plan. This excludes shares to be issued under the ESPP because the number of shares to be issued on future purchase dates is not determinable as the closing stock price on those future purchase dates is an input to the calculation of shares to be issued. 

<sup>(3)</sup> Consists of the weighted-average exercise price of the 5,551,227 stock options outstanding on December 31, 2025 and does not include RSUs, which do not have an exercise price, or purchase rights under the ESPP.

<sup>(4)</sup> Consists of (i) 16,103,152 shares that remained available for future issuance under the 2020 Plan as of December 31, 2025 and (ii) 3,982,245 shares that remained available for future issuance under the ESPP as of December 31, 2025. No shares remained available for future issuance under the 2012 Plan as of December 31, 2025. 

<sup>(5)</sup> We do not have any compensation plans that were not approved by stockholders nor have we granted any inducement awards.

<sup>(6)</sup> The 2020 Plan has an evergreen provision that allows for an annual increase in the number of shares available for issuance under the 2020 Plan to be added on the first day of each fiscal year, beginning in fiscal year 2021 and ending on the second day of fiscal year 2030. The evergreen provision provides for an automatic increase in the number of shares available for issuance equal to the lesser of (i) 4% of the number of outstanding shares of common stock on such date and (ii) an amount determined by the plan administrator. 

<sup>(7)</sup> The ESPP has an evergreen provision that allows for an annual increase in the number of shares available for issuance under the ESPP to be added on the first day of each fiscal year, beginning in fiscal year 2025 and ending on the second day of fiscal year 2033. The evergreen provision provides for an automatic increase in the number of shares available for issuance equal to the lesser of (i) 2,076,487 shares, which is 1% of the number of outstanding shares of common stock on December 31, 2023 and (ii) an amount determined by the plan administrator.

### REPORT OF AUDIT COMMITTEE
The audit committee of our board of directors, which consists entirely of directors who meet the independence and experience requirements of the NYSE, has furnished the following report:

The audit committee assists our board of directors in overseeing and monitoring the integrity of our financial reporting process, compliance with legal and regulatory requirements and the quality of internal and external audit processes. This committee's role and responsibilities are set forth in our charter adopted by our board of directors, which is available on our website at www.butterflynetwork.com. This committee reviews and reassesses our charter annually and recommends any changes to our board of directors for approval. The audit committee is responsible for overseeing our overall financial reporting process, and for the appointment, compensation, retention, and oversight of the work of Deloitte & Touche LLP. In fulfilling its responsibilities for the financial statements for fiscal year ended December 31, 2025, the audit committee took the following actions:

• Reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2025 with management and Deloitte & Touche LLP, our independent registered public accounting firm;

• Discussed with Deloitte & Touche LLP the matters required to be discussed in accordance with Auditing Standard No. 1301 - Communications with audit committees; and

• Received written disclosures and the letter from Deloitte & Touche LLP as required by applicable requirements of the Public Company Accounting Oversight Board regarding Deloitte & Touche LLP's communications with the audit committee concerning independence, and the audit committee further discussed with Deloitte & Touche LLP their independence. The audit committee also considered the status of pending litigation, taxation matters and other areas of oversight relating to the financial reporting and audit process that the committee determined appropriate.

Based on the audit committee's review of the audited financial statements and discussions with management and Deloitte & Touche LLP, the audit committee recommended to our board of directors that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 for filing with the SEC.

### Indemnification Agreements with Officers and Directors and Directors' and Officers' Liability Insurance
We have entered into indemnification agreements with each of our executive officers and directors. The indemnification agreements and our amended and restated bylaws require that we indemnify and advance expenses to our directors and officers to the fullest extent permitted by applicable law in effect on the date thereof or as amended to increase the scope of permitted indemnification, for any and all losses (including all interest and assessments and other charges in connection therewith) actually and reasonably incurred by the indemnitee or on the indemnitee's behalf in connection with any proceeding in any way connected with, resulting from or relating to the indemnitee's status as a director or officer. We also maintain a general liability insurance policy, which covers certain liabilities of our directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers.

#### Procedures for Related Party Transactions
We have adopted a related person transaction procedure that sets forth the following policies and procedures for the review and approval or ratification of related person transactions.

A "Related Person Transaction" is a transaction, arrangement or relationship in which we or any of our subsidiaries was, is or will be a participant, the amount of which involved exceeds $120,000, and in which any related person had, has or will have a direct or indirect material interest. Transactions involving compensation for services provided to us or any of our subsidiaries as an employee, consultant or director will not be considered related person transactions under this policy. A "Related Person" is:

• any person who is or was an executive officer, director, or director nominee of the Company at any time since the beginning of the Company's last fiscal year;

• a person who is or was an Immediate Family Member (as defined below) of an executive officer, director, director nominee at any time since the beginning of the Company's last fiscal year;

• any person who, at the time of the occurrence or existence of the transaction, is the beneficial owner of more than 5% of any class of the Company's voting securities (a "Significant Stockholder"); or

• any person who, at the time of the occurrence or existence of the transaction, is an Immediate Family Member of a Significant Stockholder of the Company.

#### **TABLE OF CONTENTS**
An "Immediate Family Member" of a person is any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of such person, or any other person sharing the household of such person, other than a tenant or employee.

We have implemented policies and procedures designed to minimize potential conflicts of interest arising from any dealings we may have with our affiliates and to provide appropriate procedures for the disclosure of any real or potential conflicts of interest that may exist from time to time. Specifically, pursuant to its charter, the audit committee has the responsibility to review related party transactions.

Under the related person transaction policy, the related person in question or, in the case of transactions with a beneficial holder of more than 5% of the Company's voting stock, an officer with knowledge of a proposed transaction, will be required to present information regarding the proposed related person transaction to the audit committee (or to another independent body of the board of directors) for review. To identify related person transactions in advance, we expect to rely on information supplied by our executive officers, directors and certain significant stockholders. In considering related person transactions, our audit committee is expected to take into account the relevant available facts and circumstances, which may include, but are not limited to:

• the related person's interest in the transaction;

• the approximate dollar value of the amount involved in the transaction;

• the approximate dollar value of the amount of the related person's interest in the transaction without regard to the amount of any profit or loss;

• whether the transaction was undertaken in the ordinary course of business of the Company;

• whether the transaction with the related person is proposed to be, or was, entered into on terms no less favorable to the Company than terms that could have been reached with an unrelated third party;

• the purpose of, and the potential benefits to the Company of, the transaction; and

• any other information regarding the transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

The audit committee will approve only those transactions that it determines are fair to the Company and in the Company's best interests.

Louise Phanstiel, and Erica Schwartz, M.D., J.D., M.P.H. for election at the annual meeting. If each such director nominee is elected, he or she will serve on our board of directors until the 2027 annual meeting of stockholders and until his or her respective successor has been elected and qualified or until his or her earlier death, resignation, disqualification or removal.

Unless authority to vote for any of these nominees is withheld, the shares represented by the enclosed proxy will be voted FOR the election of Joseph DeVivo, Jonathan M. Rothberg, Ph.D., Larry Robbins, Elazer Edelman, M.D., Ph.D., Caroll H. Neubauer, S. Louise Phanstiel, and Erica Schwartz, M.D., J.D., M.P.H. as directors.

We have no reason to believe that any nominee will be unable or unwilling to serve as a director.

### Vote Requirement and Recommendation of the Board of Directors
The affirmative vote of a majority of the votes cast is required to elect each nominee as a director. Abstentions and broker non-votes will have no effect on the election of directors.

## Proposal 2: Ratification of Appointment of Independent Registered Public Accounting Firm
The audit committee has appointed Deloitte & Touche LLP ("Deloitte") as our independent registered public accounting firm, to audit our financial statements for the fiscal year ending December 31, 2026. Our board of directors proposes that the stockholders ratify this appointment. We expect that representatives of Deloitte will be present at the annual meeting, will be able to make a statement if they so desire, and will be available to respond to appropriate questions.

In deciding to appoint Deloitte as our independent registered public accounting firm to audit our financial statements for the fiscal year ending December 31, 2026, the audit committee reviewed auditor independence considerations and existing commercial relationships with Deloitte and concluded that Deloitte has no commercial relationship with the Company that would impair its independence for the fiscal year ending December 31, 2026.

The following table sets forth the fees billed to or incurred by our Company for professional services rendered by Deloitte, our independent registered public accounting firm, for the audit of our annual consolidated financial statements (including the consolidated financial statements of Legacy Butterfly) for the years ended December 31, 2025 and 2024, and fees billed for other services rendered by Deloitte during those periods:

&nbsp;&nbsp;&nbsp;&nbsp;(1) *Audit Fees . Audit fees consisted of professional services rendered for the audit of our annual consolidated financial statements, review of our quarterly consolidated financial statements, consents, comfort letters, and services in connection with documents filed with the SEC.* 

#### Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Public Accountant
Consistent with SEC policies regarding auditor independence, the audit committee has responsibility for appointing, setting compensation and overseeing the work of our independent registered public accounting firm. In recognition of this responsibility, the audit committee has established a policy to pre-approve all audit and permissible non-audit services provided by our independent registered public accounting firm.

Prior to engagement of an independent registered public accounting firm for the next year's audit, management will submit an aggregate of services expected to be rendered during that year for each of four categories of services to the audit committee for approval.

1. *Audit* services include services performed in the audit and review of financial statements, as well as work that generally only an independent registered public accounting firm can reasonably be expected to provide, including comfort letters, statutory audits, and attest services and consultation regarding financial accounting or reporting standards.

2. *Audit-Related* services are for assurance and related services that are traditionally performed by an independent registered public accounting firm, including due diligence related to mergers and acquisitions, employee benefit plan audits, and special procedures required to meet certain regulatory requirements.

3. *Tax* services include all services performed by an independent registered public accounting firm's tax personnel except those services specifically related to the audit of the financial statements, and include fees in the areas of tax compliance, tax planning, and tax advice.

4. *Other Fees* are those associated with services not captured in the other categories. The Company generally does not request such services from our independent registered public accounting firm.

#### **TABLE OF CONTENTS**
Prior to engagement, the audit committee pre-approves these services by category of service. The fees are budgeted and the audit committee requires our independent registered public accounting firm and management to report actual fees versus the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage our independent registered public accounting firm for additional services not contemplated in the original pre-approval. In those instances, the audit committee requires specific pre-approval before engaging our independent registered public accounting firm.

The audit committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the audit committee at its next scheduled meeting.

In the event the stockholders do not ratify the appointment of Deloitte as our independent registered public accounting firm, the audit committee will reconsider its appointment.

### Vote Requirement and Recommendation of the Board of Directors
The affirmative vote of a majority of the votes cast at the annual meeting is required to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. Abstentions and broker non-votes, if any, will have no effect on the outcome of the vote on this proposal.

**OUR BOARD OF DIRECTORS RECOMMENDS A VOTE TO RATIFY THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2026, AND PROXIES SOLICITED BY OUR BOARD OF DIRECTORS WILL BE VOTED IN FAVOR OF SUCH RATIFICATION UNLESS A STOCKHOLDER INDICATES OTHERWISE ON THE PROXY.**

## Proposal 3: Non-Binding Advisory Vote on Approval of the Compensation of our Named Executive Officers, as Disclosed in this Proxy Statement
We are seeking your advisory vote as required by Section 14A of the Exchange Act, on the approval of the compensation of our NEOs as described in the Executive and Director Compensation section, the compensation tables and related material contained in this proxy statement. Because your vote is advisory, it will not be binding on our compensation committee or our board of directors. However, the compensation committee and our board of directors will review the voting results and take them into consideration when making future decisions regarding executive compensation.

Our compensation program is structured to attract, motivate and retain highly qualified executive officers by paying them competitively, consistent with our success and their contributions to that success. We require top talent with a wide range of skills, experience, and leadership qualities to lead the organization in support of our mission to democratize healthcare and to make medical imaging accessible to everyone around the world by using our proprietary technology. In order to attract and retain the talent required to fulfill our mission, accelerate growth, and promote stockholder value, the compensation committee's goal is to implement an executive compensation program that is built upon strategic objectives.

Stockholders are urged to read the Executive and Director Compensation section of this proxy statement, which discusses how our compensation policies and procedures implement our compensation philosophy. The compensation committee and our board of directors believe that these policies and procedures are effective in implementing our compensation philosophy and in achieving its goals.

In accordance with the rules of the SEC, the following resolution, commonly known as a "say-on-pay" vote, is being submitted for a stockholder vote at the 2026 annual meeting:

"RESOLVED, that the compensation paid to the NEOs of Butterfly Network, Inc., as disclosed in the proxy statement for the 2026 Annual Meeting of Stockholders pursuant to Section 14A of the Exchange Act, including the summary compensation table and other executive compensation tables, the narrative disclosures that accompany the compensation tables and the related material disclosed in the proxy statement, is hereby APPROVED."

At our 2022 annual meeting of stockholders, our stockholders voted in favor of holding future "say-on-pay" votes every year, as recommended by our board of directors. Accordingly, we expect that the next "say-on-pay" vote will occur at the 2027 annual meeting of stockholders.

### Vote Requirement and Recommendation of the Board of Directors
The affirmative vote of a majority of the votes cast at the annual meeting is required to approve, on an advisory basis, this proposal. Abstentions and broker non-votes will have no effect on the outcome of the vote on this proposal.

**OUR BOARD OF DIRECTORS RECOMMENDS A VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AND PROXIES SOLICITED BY OUR BOARD OF DIRECTORS WILL BE VOTED IN FAVOR OF SUCH APPROVAL UNLESS A STOCKHOLDER INDICATES OTHERWISE ON THE PROXY.**

### OTHER MATTERS
Our board of directors knows of no other business which will be presented to the annual meeting. If any other business is properly brought before the annual meeting, proxies will be voted in accordance with the judgment of the persons named therein.

### STOCKHOLDER PROPOSALS AND NOMINATIONS FOR DIRECTOR
To be considered for inclusion in the proxy statement relating to our 2027 annual meeting of stockholders, we must receive stockholder proposals (other than for director nominations) in accordance with the procedures outlined in Rule 14a-8 of the Exchange Act no later than December 28, 2026. However, if the date of the 2027 annual meeting of stockholders is changed by more than 30 days from the anniversary date of the previous year's meeting, then the deadline is a reasonable time before we begin to print and send our proxy statement for the 2027 annual meeting of stockholders. SEC rules set forth standards for eligibility and specify the types of stockholder proposals that may be excluded from a proxy statement.

If a stockholder wishes to propose a nomination of persons for election to our board of directors or present a proposal at an annual meeting but does not wish to have the proposal considered for inclusion in our proxy statement and proxy card, our amended and restated bylaws establish an advance notice procedure for such nominations and proposals. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the board of directors or by a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered timely notice in proper form to our Corporate Secretary of the stockholder's intention to bring such business before the meeting.

The required notice must be in writing and received by our Corporate Secretary at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year's annual meeting. However, in the event that the date of the 2027 annual meeting of stockholders is advanced by more than 30 days, or delayed by more than 70 days, from the first anniversary of the 2026 annual meeting of stockholders, a stockholder's notice must be so received no later than the close of business of the 90th day prior to the 2027 annual meeting of stockholders or the 10th day following the day on which notice of the date of the 2027 annual meeting of stockholders was first made, whichever first occurs. For stockholder proposals to be brought before the 2027 annual meeting of stockholders, the required notice must be received by our Corporate Secretary at our principal executive offices no earlier than close of business on February 18, 2027, and no later than close of business on March 20, 2027. All stockholder proposals should be marked for the attention of Corporate Secretary and sent to Butterfly Network, Inc., 1600 District Avenue, Burlington, Massachusetts 01803 and via email to legal@butterflynetinc.com.

In addition to satisfying the foregoing requirements, to comply with Rule 14a-19 under the Exchange Act, the SEC's universal proxy rule, stockholders who intend to solicit proxies in support of director nominees other than our board of directors' nominees must provide notice by April 19, 2027 to submit a notice of nomination at an annual meeting of stockholders. The deadline under Rule 14a-19(b) is a minimum notice requirement that does not override or supersede the earlier deadline in our amended and restated bylaws. A stockholder intending to solicit proxies in support of director nominees other than our nominees must satisfy the requirements of both our amended and restated bylaws and Rule 14a-19, which imposes conditions beyond those in our amended and restated bylaws. Rule 14a-19(b) requires that the stockholder's notice to us must include the names of all nominees for whom the stockholder intends to solicit proxies and must include a statement that the stockholder intends to solicit the holders of shares representing at least 67% of the voting power of shares entitled to vote on the election of directors in support of director nominees other than our nominees. Such notice should be marked for the attention of Corporate Secretary at the address above.
