Sentiment and the balance of points

Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

remaining performance obligations financial
"had $84.2 million of remaining performance obligations"
Remaining performance obligations are the work a company still needs to complete for its customers, like finishing a service or delivering a product. It’s important because it shows how much future income the company has coming in from current agreements, giving a clearer picture of its ongoing business.

Rule 10b5-1 trading arrangement regulatory
"adopted a “Rule 10b5-1 trading arrangement”"
restricted cash financial
"held as collateral to secure a letter of credit"
Cash that a company holds but cannot use for day-to-day operations because it is set aside for a specific purpose—such as meeting loan covenants, serving as collateral, funding an escrow, or complying with regulations. Like money in a locked savings account earmarked for a bill, restricted cash reduces the cash available to run the business and pay dividends or debts, so investors treat it differently when assessing a company’s true short-term financial strength.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), that relate to future events or our future financial performance regarding, among other things, our plans, strategies, and prospects, both business and financial. These statements are based on the beliefs and assumptions of our management team. Generally, statements that are not historical facts, including statements concerning possible or assumed future actions, business strategies, events, or results of operations, are forward-looking statements. Forward-looking statements contained in this Quarterly Report on Form 10-Q include, but are not limited to, statements about:
•the success, cost, and timing of our product development activities, including the development of additional potential products;
•the potential attributes and benefits of our products and services;
•our ability to obtain and maintain regulatory authorization for our products, and any related restrictions and limitations on the use of any authorized product;
•our ability to identify, in-license, or acquire additional technology;
•our ability to maintain our existing license, manufacturing, and supply agreements;
•the success, cost, and timing of our efforts to out-license our intellectual property to third parties;
•our ability to compete with other companies currently marketing or engaged in the development of ultrasound imaging devices, many of which have greater financial and marketing resources than us;
•the size and growth potential of the markets for our products and services, and the ability of each to serve those markets, either alone or in partnership with others;
•our estimates regarding expenses, revenue, capital requirements, and needs for additional financing; and
•our financial performance.
These statements may be preceded by, followed by, or include the words "believes," "estimates," "expects," "projects," "forecasts," "may," "will," "should," "seeks," "plans," "scheduled," "anticipates," or "intends" or similar expressions or phrases, or the negative of those expressions or phrases. The forward-looking statements are based on projections prepared by, and are the responsibility of, our management. Although we believe that our plans, intentions, and expectations reflected in or suggested by these forward-looking statements are reasonable, we cannot assure you that we will achieve or realize these plans, intentions, or expectations. Forward-looking statements are inherently subject to risks, uncertainties, and assumptions relating to, among other things:
•our growth depends on our ability to attract and retain customers;
•our business could be harmed if we fail to manage our growth effectively;
•our current expectations and assumptions are subject to risks, assumptions, estimates, and uncertainties;
•our business is subject to a variety of U.S. and foreign laws, which are subject to change and could adversely affect our business;
•the pricing of our products and services, and reimbursement for medical procedures conducted using our medical products and services;
•changes in applicable laws or regulations;
•our ability to protect or enforce our intellectual property rights; and
•economic downturns and political and market conditions beyond our control.
These and other risks and uncertainties are described in greater detail under the caption "Risk Factors" in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2025 (the "2025 Annual Report on Form 10-K"), in Item 1A of Part II of this Quarterly Report on Form 10-Q, and in other filings that we make with the Securities and Exchange Commission ("SEC"). The risks described under the caption "Risk Factors" are not exhaustive. New risk factors emerge from time to time, and it is not possible to predict all such risk factors, nor can we assess the impact of all such risk factors on our business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. Forward-looking statements are not guarantees of performance. You should not put undue reliance on these statements, which speak only as of the date hereof. All forward-looking statements attributable to the Company or persons acting on the Company’s behalf are expressly qualified in their entirety by the foregoing cautionary statements. We undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
Note 1. Organization and Description of Business
Butterfly Network, Inc., formerly known as Longview Acquisition Corp. ("Longview"), was incorporated in Delaware on February 4, 2020. Following a business combination between the Company and BFLY Operations, Inc. (formerly Butterfly Network, Inc.) on February 12, 2021 (the "Business Combination"), the Company’s legal name became Butterfly Network, Inc.
The Company is an innovative digital health business transforming care through a unique combination of portable, semiconductor-based ultrasound technology, intuitive software, services, and educational offerings that can make medical imaging more accessible than ever before. Butterfly’s solution enables the practical application of ultrasound information into the clinical workflow through affordable hardware that fits in a healthcare professional’s pocket and is paired with cloud-connected software that is easily accessed through a mobile application. The Company also licenses its proprietary Ultrasound-on-Chip™ semiconductor platform for co-development of novel technologies in non-competitive markets through a program called Butterfly Embedded™ ("Embedded").
The Company operates wholly-owned subsidiaries in the United States, Australia, Germany, the Netherlands, Taiwan, and the United Kingdom.
Note 2. Summary of Significant Accounting Policies
Basis of Presentation and Principles of Consolidation
The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with generally accepted accounting principles in the U.S. ("U.S. GAAP") and the accounting disclosure rules and regulations of the SEC regarding interim financial reporting. Certain information and note disclosures normally included in the annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the 2025 Annual Report on Form 10-K. All intercompany balances and transactions are eliminated upon consolidation. Certain amounts in these condensed consolidated financial statements and related footnotes may not foot or crossfoot due to rounding.
The condensed consolidated balance sheet as of December 31, 2025, included herein, was derived from the audited consolidated financial statements as of that date but does not include all disclosures, including certain notes, required by U.S. GAAP for annual reporting.
In the opinion of management, the accompanying condensed consolidated financial statements reflect all normal and recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods. The results for the three and nine months ended September 30, 2026 are not necessarily indicative of the results to be expected for any subsequent quarter, the year ending December 31, 2026, or any other period.
Use of Estimates
The Company makes estimates and assumptions about future events that affect the amounts reported in its condensed consolidated financial statements and accompanying notes. Future events and their effects cannot be determined with certainty. On an ongoing basis, management evaluates these estimates and assumptions.
The Company bases these estimates on historical and anticipated results and trends and on various other assumptions that the Company believes are reasonable under the circumstances, including assumptions about future events. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates, and any such differences may be material to the Company’s condensed consolidated financial statements.
The Company revised its estimated liabilities for loss contingencies and recognized an insurance recovery asset during the three and nine months ended September 30, 2026. The following table summarizes the effects of the Company's revised

Table of Contents
estimates on captions in the condensed consolidated statements of operations and comprehensive loss (in thousands, except per-share amounts):
Three months ended September 30, 2026Nine months ended September 30, 2026
Loss from operations $(600)$2,150 
Net loss and comprehensive loss$(600)$2,150 
Net loss per common share attributable to Class A and B common stockholders, basic and diluted$— $0.01 
See Note 12 "Commitments and Contingencies" for additional information on the losses and loss recovery related to these estimated liabilities and insurance recovery asset, respectively. There have been no other material changes to the Company’s use of estimates as described in the consolidated financial statements for the year ended December 31, 2025.
Concentration of Credit Risk
Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents and accounts receivable. As of September 30, 2026, the Company’s cash and cash equivalents consisted primarily of bank deposits and money market accounts. The Company maintains its bank deposits in various operating accounts above federally insured limits. The Company maintains its money market accounts with one financial institution. The Company has not experienced any significant losses on such accounts and does not believe it is exposed to any significant credit risk on its cash and cash equivalents.
As of September 30, 2026 and December 31, 2025, two customers and no customers, respectively, accounted for more than 10% of the Company’s accounts receivable. For the three months ended September 30, 2026, two customers each accounted for more than 10% of the Company’s total revenue. For the nine months ended September 30, 2026, one customer accounted for more than 10% of the Company’s total revenue. For the three and nine months ended September 30, 2025, no customers accounted for more than 10% of the Company’s total revenue.
Segment Information
The Company has determined that it operates in one reportable segment, which includes all activities related to the development, manufacture, and sale of the Company's products, software, and other services. The Company’s chief operating decision maker ("CODM"), its Chief Executive Officer, regularly reviews the Company's consolidated net loss, which is reported as net loss and comprehensive loss on the condensed consolidated statements of operations and comprehensive loss, for purposes of evaluating the Company's financial performance, including reviewing budget versus actual results, and determining changes in the Company's allocation of resources across the Company's strategic initiatives. The Company's measure of segment assets is total assets, as reported on the condensed consolidated balance sheets, and substantially all of the Company’s long-lived assets are located in the United States.
In addition to the operating expenses presented on the condensed consolidated statements of operations and comprehensive loss, the CODM also reviews certain significant segment expenses. The following table summarizes the Company's segment revenue and significant segment expenses included in consolidated net loss (in thousands):

Because the Company operates in one reportable segment, other required segment disclosures are included on the Company's condensed consolidated financial statements. Interest income, interest expense, and the provision for income taxes are included on the condensed consolidated statements of operations and comprehensive loss. Depreciation, amortization, and impairments; write-down of inventories; and purchases of property, equipment, and intangible assets, including capitalized software, are included on the condensed consolidated statements of cash flows.

Recent Accounting Pronouncements Issued but Not Yet Adopted
The Company considers the applicability and impact of all Accounting Standards Updates ("ASUs") issued by the Financial Accounting Standards Board ("FASB"). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on the Company’s consolidated financial statements.
11

Table of Contents
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which introduced new guidance on disclosures of specified information about certain costs and expenses included within expenses presented on the face of the income statements, such as purchases of inventory and employee compensation. This guidance is effective for the Company for annual reporting periods beginning January 1, 2027 and interim reporting periods beginning January 1, 2028. The Company is currently evaluating the impact that the adoption of this pronouncement will have on the Company's consolidated financial statements and disclosures.
In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which introduced new guidance to modernize the accounting for internal-use software development costs by removing references to prescriptive and sequential software development stages and providing additional considerations when evaluating the probable-to-complete recognition threshold. This guidance is effective for the Company for both annual and interim periods beginning January 1, 2028. The new guidance may be adopted using either a prospective, modified, or retrospective transition approach. The Company is currently evaluating the impact that the adoption of this pronouncement will have on the Company's consolidated financial statements and disclosures, including which transition approach the Company expects to use.

The Company disaggregates revenue from contracts with customers by type of good or service, geographical market, and business line. For the business line disaggregation, the Company considers revenue from its core business to be all revenue generated by activities outside of its Embedded business line. The Company believes that these categories aggregate the payor types by nature, amount, timing, and uncertainty of its revenue streams. The following table summarizes the Company’s disaggregated revenue (in thousands):

Contract Balances
Contract balances represent amounts presented in the condensed consolidated balance sheets when the Company has either transferred goods or services to the customer or the customer has paid consideration to the Company under the contract. These contract balances include trade accounts receivable and deferred revenue. The Company recognizes a receivable when it has an unconditional right to payment, and payment terms are typically 30 to 90 days for sales on credit of product, software, and other services. For the three months ended September 30, 2026 and 2025, the Company recognized $6.2 million and $5.2 million, respectively, of revenue that was included in the deferred revenue balance at the beginning of the period. For the nine months ended September 30, 2026 and 2025, the Company recognized $25.4 million and $14.2 million, respectively, of revenue that was included in the deferred revenue balance at the beginning of the period.

Transaction Price Allocated to Remaining Performance Obligations
As of September 30, 2026 and December 31, 2025, the Company had $84.2 million and $99.6 million, respectively, of remaining performance obligations. As of September 30, 2026, the Company expects to recognize 60% of its remaining performance obligations as revenue in the next twelve months and an additional 40% thereafter.
Note 4. Fair Value of Financial Instruments
Fair value estimates of financial instruments are made at a specific point in time, based on relevant information about financial markets and specific financial instruments. As these estimates are subjective in nature, involving uncertainties and matters of significant judgment, they cannot be determined with precision. Changes in assumptions can significantly affect estimated fair value.
The Company measures fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The Company utilizes a three-tier hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:
•Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities that an entity has the ability to access.
•Level 2 — Valuations based on quoted prices for similar assets or liabilities, quoted prices for identical assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
•Level 3 — Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company has no assets or liabilities valued with Level 3 inputs.
The carrying values of cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses approximate their fair values due to the short-term or on-demand nature of these instruments.
There were no transfers between fair value measurement levels during the periods ended September 30, 2026 and December 31, 2025.
All of the Company’s unexercised warrants expired at the end of their contractual exercise period on February 12, 2026. These warrants included publicly traded warrants (the "Public Warrants"), which were issued as one-third of a warrant per unit during Longview’s initial public offering, and warrants sold in a private placement to Longview’s sponsor (the "Private Warrants"). Each whole warrant entitled the registered holder to purchase one share of Class A common stock at an exercise price of $11.50 per share, subject to adjustment per the warrant agreements. The Company recognizes the change in fair value of warrant liabilities in the condensed consolidated statements of operations and comprehensive loss. No warrants were exercised during the three and nine months ended September 30, 2026 and 2025.
The Company measured its Public Warrants using Level 1 fair value inputs based on quoted prices in active markets for the Public Warrants. Because any transfer of Private Warrants from the initial holder of the Private Warrants would result in the Private Warrants having substantially the same terms as the Public Warrants, management determined that the fair value of each Private Warrant was the same as that of a Public Warrant. Accordingly, the Company measured its Private Warrants using Level 2 fair value inputs based on quoted prices in active markets for the Public Warrants.
The Company did not have any assets or liabilities that are measured at fair value on a recurring basis as of September 30, 2026. The Company did not have any assets that are measured at fair value on a recurring basis as of December 31, 2025. The following table summarizes the Company’s liabilities that are measured at fair value on a recurring basis as of December 31, 2025, by level within the fair value hierarchy (in thousands):

Outstanding at September 30, 202616,636,780
Generally, each award vests based on continued service per the award agreement. The grant date fair value of the award is recognized as stock-based compensation expense over the requisite service period. The grant date fair value was determined based on the fair market value of the Company’s Class A common stock on the grant date.
Included in the table above are market-based RSUs granted between 2023 and 2025 that include a service condition. The market-based conditions for these awards are objective metrics related to the Company’s stock price defined in the award agreements. The service condition for these awards is satisfied by providing service to the Company through the achievement date of the market-based conditions. The grant date fair value of the awards is recognized as stock-based compensation expense over the derived service period. The grant date fair value and derived service period were determined by using a Monte Carlo simulation with similar assumptions as those previously disclosed by the Company.
Award Accelerations and Modifications
During the third quarter of 2026, certain service-based RSUs of an external consultant had their vesting accelerated by one year. In total, 0.7 million RSUs had their vesting accelerated. For the three and nine months ended September 30, 2026, the incremental stock-based compensation expense resulting from the acceleration was $0.9 million.
Employee Stock Purchase Plan
For the three and nine months ended September 30, 2026, there were no significant changes to the Company’s 2024 Employee Stock Purchase Plan (the “ESPP”). On January 1, 2026, pursuant to the terms of the ESPP, the number of shares reserved for issuance was increased automatically by 1% of the number of shares of common stock issued and outstanding on December 31, 2023.
No shares of common stock were issued under the ESPP during the three months ended September 30, 2026 and 2025. 1.3 million and 1.1 million shares of common stock were issued under the ESPP during the nine months ended September 30, 2026 and 2025, respectively.

Note 10. Net Loss Per Share
We compute net loss per share of Class A and Class B common stock using the two-class method. Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of each class of the Company’s common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of the

Company’s common stock, including those presented in the table below, to the extent dilutive. Basic and diluted net loss per share were the same for each period presented as the inclusion of all potential shares of the Company’s common stock outstanding would have been anti-dilutive.
As the Company uses the two-class method required for companies with multiple classes of common stock, the following tables present the calculation of basic and diluted net loss per share for each class of the Company’s common stock outstanding (in thousands, except share and per share amounts):

For the periods presented above, the net loss per share amounts are the same for Class A and Class B common stock because the holders of each class are entitled to equal per share dividends or distributions in liquidation in accordance with the Company's certificate of incorporation, as amended and restated. The undistributed earnings for each period are allocated based on the contractual participation rights of the Class A and Class B common stock as if the earnings for the period had been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis.

Note 11. 401(k) Retirement Plan
The Company sponsors a 401(k) defined contribution plan covering all eligible U.S. employees. Contributions to the 401(k) plan are discretionary. For the three months ended September 30, 2026 and 2025, expenses for matching 401(k) contributions were $0.1 million and $0.1 million, respectively. For the nine months ended September 30, 2026 and 2025, expenses for matching 401(k) contributions were $0.4 million and $0.4 million, respectively.
Note 12. Commitments and Contingencies
Commitments
Leases:
The Company primarily enters into leases for office space that are classified as operating leases. For the three months ended September 30, 2026 and 2025, total lease cost was $0.7 million and $0.8 million, respectively. For the nine months ended September 30, 2026 and 2025, total lease cost was $2.2 million and $2.2 million, respectively. Total lease cost was primarily composed of operating lease costs.
Purchase Commitments:
The Company enters into inventory purchase commitments with third-party manufacturers in the ordinary course of business, including a non-cancellable inventory supply agreement with a certain third-party manufacturing vendor. The provisions of the agreement allowed the Company, once it reached a certain cumulative purchase threshold in the fourth
18

Table of Contents
quarter of 2021, to pay for a portion of the subsequent inventory purchases using an advance previously paid to the vendor. As of September 30, 2026, the Company has fully satisfied its non-cancellable inventory supply agreement.
The Company applied the guidance in Accounting Standards Codification Topic 330, Inventory to assess the purchase commitment and related loss, using such factors as Company-specific forecasts which are reliant on the Company’s limited sales history, agreement-specific provisions, macroeconomic factors, and market and industry trends. For the three and nine months ended September 30, 2026 and 2025, the Company did not recognize any additions to the accrued purchase commitment liability, or any related losses, based on its purchase commitment assessment as there were no significant changes to the assessment factors.
The Company reviews its inventory on hand, including inventory acquired under the purchase commitments, for excess and obsolescence ("E&O") on a quarterly basis. Any E&O inventory acquired that was previously accounted for as a purchase commitment liability accrual or vendor advance write down is recorded at zero value. During the three and nine months ended September 30, 2026 and 2025, the Company did not acquire a significant amount of such E&O inventory.
Contingencies
The Company is involved in litigation and legal matters from time to time, which have arisen in the normal course of business. The Company accrues an estimated liability for legal contingencies when the Company considers a potential loss probable and can reasonably estimate the amount of the potential loss. Although the ultimate results of these matters are not currently determinable, other than with respect to the estimated liabilities for loss contingencies described below, management does not expect that they will have a material effect on the Company’s condensed consolidated balance sheets, statements of operations and comprehensive loss, or statements of cash flows.
On February 16, 2022, a putative class action lawsuit, styled Rose v. Butterfly Network, Inc., et al. was filed in the United States District Court for the District of New Jersey. The claims are against the Company and certain of its directors and previous management as well as members of the board of directors of the Company prior to the completion of the Business Combination, alleging that the defendants made false and misleading statements and/or omissions about the Company's post-Business Combination business and financial prospects. The alleged class consists of all persons or entities who purchased or otherwise acquired the Company’s stock between January 12, 2021 and November 15, 2021, persons who exchanged Longview shares for the Company’s common stock, and persons who purchased Longview stock pursuant to, or traceable to, the Company's Proxy/Registration Statement on Form S-4 filed with the SEC on November 27, 2020 or any amendment thereto. The Company intends to vigorously defend against this action. The lawsuit seeks unspecified damages, together with interest thereon, as well as the costs and expenses of litigation. There is no assurance that the Company will be successful in the defense of the litigation or that insurance will be available or adequate to fund any potential settlement or judgment or the litigation costs of the action. During the nine months ended September 30, 2026, the Company recognized an estimated liability of $0.3 million for a loss contingency in connection with this litigation. There were no changes to the Company's estimate during the three months ended September 30, 2026. The estimated liability is included in accrued expenses and other current liabilities on the condensed consolidated balance sheets, and the estimated loss is included in other on the condensed consolidated statements of operations and comprehensive loss.
On June 21, 2022, a stockholder derivative action, styled Koenig v. Todd M. Fruchterman, et al. was filed in the United States District Court for the District of Delaware against the Company’s board of directors and the Company as nominal defendant. On November 28, 2023, a stockholder derivative action, styled Bhavsar v. Todd M. Fruchterman, et al. was filed in the United States District Court for the District of Delaware against the board of directors and the Company as nominal defendant. Both these actions allege violation of Section 14(a) of the Exchange Act and Rule 14a-9 promulgated thereunder, and claims for breach of fiduciary duty, contribution and indemnification, aiding and abetting, and gross mismanagement. The lawsuits are premised upon allegedly inadequate internal controls and purportedly misleading representations regarding the Company’s financial condition, business prospects, and the Company’s November 2021 earnings announcement. The Company intends to vigorously defend against these actions. The lawsuits seek unspecified damages, disgorgement, and restitution, together with interest thereon, as well as the costs and expenses of litigation. There is no assurance that the Company will be successful in the defense of the litigation or that insurance will be available or adequate to fund any potential settlement or judgment or the litigation costs of the action. The Company is unable to predict the outcome or reasonably estimate a range of possible loss at this time.
In the ongoing civil action styled Sezonov v. Longview Investors LLC, et al., a stockholder is pursuing claims on behalf of a putative class arising from the Business Combination. The stockholder filed her complaint on December 13, 2023 in the Court of Chancery of the State of Delaware against two entities affiliated with Longview, and four former members of the Longview board of directors (including Larry Robbins, who also is a current member of the Company’s board of directors).

Table of Contents
The complaint asserts claims for breaches of fiduciary duty, unjust enrichment, civil conspiracy and aiding and abetting breaches of fiduciary duty, and seeks unspecified damages. The case is currently in the discovery phase and has not yet reached the class certification stage. The Company has produced documents to the plaintiff in the case pursuant to a non-party subpoena. The Company’s understanding is that the defendants in this action intend to continue to vigorously defend the claims pending against them. There is no assurance that the defendants will be successful in the defense of the litigation, or that insurance will be available or adequate to fund any potential settlement or judgment or the litigation costs of the action. In the event that such insurance is not available or adequate, the Company has indemnification obligations to certain defendants in the case that may be implicated later. During the three and nine months ended September 30, 2026, the Company recognized increases of $4.3 million and $11.3 million, respectively, to its estimated liability for a loss contingency in connection with this indemnification obligation. During the nine months ended September 30, 2026, the Company also recognized a related $13.7 million insurance recovery asset, which includes an increase of $3.7 million during the three months ended September 30, 2026, that the Company has deemed probable and estimable. As of September 30, 2026, the total estimated liability for such loss contingency is $14.3 million, and the total related insurance recovery asset is $13.7 million. The estimated liability is included in accrued expenses and other current liabilities on the condensed consolidated balance sheets, the insurance recovery asset is included in prepaid expenses and other current assets on the condensed consolidated balance sheets, and both the estimated loss and loss recovery are included in other on the condensed consolidated statements of operations and comprehensive loss.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis provides information which management believes is relevant to an assessment and understanding of our condensed consolidated results of operations and financial condition. The discussion should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto contained in this Quarterly Report on Form 10-Q and the consolidated financial statements and notes thereto contained in our 2025 Annual Report on Form 10-K. This discussion contains forward-looking statements and involves numerous risks and uncertainties, including, but not limited to, those described under the caption "Risk Factors" in Item 1A of Part I of our 2025 Annual Report on Form 10-K. Actual results may differ materially from those contained in any forward-looking statements.
Overview
We are an innovative digital health business transforming care through a unique combination of portable, semiconductor-based ultrasound technology, intuitive software, services, and educational offerings that can make medical imaging more accessible than ever before. Butterfly’s solution enables the practical application of ultrasound information into the clinical workflow through affordable hardware that fits in a healthcare professional’s pocket and is paired with cloud-connected software that is easily accessed through a mobile application.
Butterfly developed ultrasound devices that can perform whole-body imaging in a single handheld probe because they are powered by our proprietary semiconductor technology instead of piezoelectric crystals. Our Ultrasound-on-Chip™ makes ultrasound more accessible outside of large healthcare institutions, while our software is intended to make the product easy to use, fully integrated with the clinical workflow, and accessible on a user’s smartphone, tablet, and almost any hospital computer system connected to the Internet. We aim to enable the delivery of imaging information anywhere at point-of-care to drive earlier detection throughout the body and remote management of health conditions. We market and sell the Butterfly system, which includes probes, related accessories, and software subscriptions (which we refer to herein as our "core business"), to healthcare systems, physicians, and healthcare providers through a direct sales force, distributors, and our eCommerce channel. We also license our proprietary Ultrasound-on-Chip™ semiconductor platform for co-development of novel technologies in non-competitive markets through our Embedded program.
Key Performance Measures
We review the key performance measures discussed below to evaluate the business and measure performance, identify trends, formulate plans, and make strategic decisions. Our key performance measures may fluctuate over time as the adoption of our devices increases, which may shift the revenue mix more toward software and other services. The quarterly measures may be impacted by the timing of device sales.
Units fulfilled
We define units fulfilled as the number of devices whereby control is transferred to a customer. We do not adjust this measure for returns as our volume of returns has historically been low. We view units fulfilled as a key indicator of the growth of our business. We believe that this measure is useful to investors because it presents our core growth and the performance of our business period over period.

Units fulfilled increased by 264 units, or 5.4%, for the three months ended September 30, 2026 compared to the three months ended September 30, 2025. This increase was largely driven by higher probe sales volume in the U.S. through direct sales to health systems, sales to our distribution partners, and sales through our eCommerce channel.
Software and other services mix
We define software and other services mix as a percentage of our total revenue recognized in a reporting period that is based on software subscriptions and other related services, consisting primarily of our Embedded program and our software as a service ("SaaS") offering. We view software and other services mix as a key indicator of the profitability of our business, and thus we believe that this measure is useful to investors.

Software and other services mix increased by 19.8 percentage points, to 52.1%, for the three months ended September 30, 2026 compared to the three months ended September 30, 2025. This increase was primarily driven by software and other services revenue generated from our various Embedded partnerships, including our co-development partnership with Midjourney, Inc.

Description of Certain Components of Financial Data
Revenue
Product revenue consists of revenue from the sale of products, such as medical devices, accessories, and semiconductor chips. Our software and other services revenue consists of revenue from the sale of SaaS subscriptions, extended warranties, services related to our Embedded partnerships, implementation and integration services, and software development kits ("SDKs"), which may be perpetual or term-based. SaaS subscriptions include licenses for teams and individuals as well as enterprise-level subscriptions. Services related to our Embedded partnerships include out-licensing arrangements and related research and development services.
For sales of products and perpetual SDKs, revenue is recognized at a point in time upon transfer of control to the customer. Sales of SaaS subscriptions, extended warranties, and term-based SDKs are generally related to stand-ready obligations or continued provision of access, and the revenue for those offerings is recognized ratably over time. For sales of services related to our Embedded partnerships and implementation and integration services, revenue is recognized over time using input methods to determine a measure of progress.
Over time, as adoption of our devices increases through further market penetration, as practitioners in the Butterfly network continue to use our devices, and as our Embedded partnerships continue to grow and develop, we expect our annual revenue mix to shift more toward software and other services. The quarterly revenue mix may be impacted by the timing of device sales.
To date, we have invested in building out our commercial footprint, with the ultimate goal of growing adoption at large-scale healthcare systems and driving awareness of the usability of ultrasound. As we expand our healthcare system software offerings and develop relationships with larger healthcare systems, we continue to expect a higher proportion of our sales in healthcare systems compared to eCommerce.
Cost of revenue
Cost of product revenue includes manufacturing costs, inbound freight, packaging, warranty replacement costs, royalty fees for licensed intellectual property, payment processing fees, and inventory obsolescence and write-offs. We expect our cost of product revenue to fluctuate over time due to the level of units fulfilled in any given period and to fluctuate as a percentage of product revenue over time as our focus on operational efficiencies in our supply chain may be offset by increased prices of certain inventory components.
Cost of software and other services revenue includes personnel costs, cloud hosting costs, and payment processing fees. Because the costs and associated expenses to deliver our software and other service offerings are less than the costs and associated expenses of manufacturing and selling our products, we anticipate an improvement in profitability and margin expansion over time as our revenue mix shifts increasingly toward software and other services. We plan to continue to invest additional resources to expand and further develop our SaaS and other service offerings which will be reflected in cost of revenue as amortization expense.
Research and development
Research and development expenses primarily consist of personnel costs and benefits, professional services, facilities-related expenses and depreciation, fabrication services, and software costs. Most of our research and development expenses are related to developing new products and services that have not reached the point of commercialization and improving our products and services that have been commercialized. Fabrication services include certain third-party engineering costs, product testing, and test boards. Research and development expenses are expensed as incurred. We expect to continue to make substantial investments in our product and software development, clinical, and regulatory capabilities.
Sales and marketing
Sales and marketing expenses primarily consist of personnel costs and benefits, advertising, conferences and events, facilities-related expenses, and software costs. We expect to increase our investments in our commercial capabilities.
General and administrative
General and administrative expenses primarily consist of personnel costs and benefits, insurance, patent fees, software costs, facilities-related expenses, and outside services. Outside services consist of professional services, legal fees, and other professional fees.

Table of Contents
Other
Operating expenses classified as other are expenses that we do not consider representative of our ongoing operations. These other expenses primarily consist of employee severance and benefits costs related to reductions in force, litigation costs, loss contingencies and related loss recoveries related to ongoing litigation, and legal settlements.
Results of Operations
We operate as a single reportable segment to reflect the way our CODM reviews and assesses the performance of the business. The accounting policies are described in Note 2 "Summary of Significant Accounting Policies" in our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

Liquidity and Capital Resources
Since our inception, our primary sources of liquidity have been cash flows from operations and proceeds from stock issuances and the Business Combination. Our primary uses of liquidity are operating expenses, working capital requirements, and capital expenditures.
During the three months ended September 30, 2026, we utilized $2.4 million of cash and cash equivalents for ongoing operations. As of September 30, 2026, our cash and cash equivalents balance was $122.3 million. Our future spending will depend on various factors, including our rate of revenue growth and the timing and extent of spending on strategic business initiatives. We expect that our existing cash and cash flows from operations will be sufficient to meet our anticipated liquidity, working capital, and capital expenditure requirements and fund our operations for at least the next 12 months.
As of September 30, 2026, we have restricted cash of $4.0 million to secure a letter of credit for one of our leases, which is expected to be maintained as a security deposit for the duration of the lease.
Our material cash requirements include contractual obligations with third parties for office leases, technology licensing agreements, and outsourced services. Our fixed office lease payment obligations were $21.5 million as of September 30, 2026, with $3.8 million payable within the next 12 months. Our fixed technology license payment obligations were $10.5 million as of September 30, 2026, with $1.5 million payable within the next 12 months. Our fixed outsourced services payment obligations were $3.1 million as of September 30, 2026, with $1.4 million payable within the next 12 months.
As of September 30, 2026, we had no obligations, assets or liabilities, which would be considered off-balance sheet arrangements.

working capital cash usage, partially offset by an improvement of $8.8 million in net loss adjusted for certain non-cash items. The $19.5 million increase in net working capital cash usage was driven by a $12.1 million increase in cash used for changes in prepaid expenses and other assets, a $10.1 million increase in cash used for changes in deferred revenue, an $8.0 million increase in cash used for changes in accounts receivable, and a $2.8 million reduction in cash provided by changes in inventory and its related vendor advances. These increases in cash usage were partially offset by a $13.5 million increase in cash provided by changes in accounts payable and accrued expenses. The $8.8 million improvement in net loss adjusted for certain non-cash items was driven by a $23.4 million improvement in net loss, partially offset by the non-recurrence of the $17.6 million of adjustments for write-downs of inventories and vendor advances.
Net cash used in investing activities
Net cash used in investing activities increased by $0.8 million, or 35.5%, for the nine months ended September 30, 2026 compared to the nine months ended September 30, 2025, primarily driven by increased investment in the development of our internal-use software.
Net cash provided by financing activities
Net cash provided by financing activities decreased by $72.1 million, or 90.8% for the nine months ended September 30, 2026 compared to the nine months ended September 30, 2025. This decrease was primarily due to the $81.0 million provided by the net proceeds from our public share offering during the prior year period, partially offset by a $6.1 million increase in cash provided by exercises and purchases of our shares pursuant to our stock plans.
Critical Accounting Policies and Significant Judgments and Estimates
This discussion and analysis of our financial condition and results of operations are based on our condensed consolidated financial statements which have been prepared in accordance with U.S. GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, contingent assets and liabilities, and related disclosures. Our estimates are based on our historical experience and various other factors that we believe are reasonable under the circumstances, and these form the basis for making judgments about items that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
As of September 30, 2026, we concluded that revisions to our estimated liabilities for loss contingencies related to ongoing litigation and a related insurance recovery asset were appropriate. As a result, we recognized an additional $4.3 million estimated loss and a $3.7 million loss recovery in our other operating expenses during the three months ended September 30, 2026. See the "Use of Estimates" subheading in Note 2 "Summary of Significant Accounting Policies" and see Note 12 "Commitments and Contingencies" in the Notes to Condensed Consolidated Financial Statements in Part I, Item 1 "Financial Statements" of this Quarterly Report on Form 10-Q for additional information about our estimated liabilities for loss contingencies and the related insurance recovery asset.
For our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q, there have been no other material changes to the critical accounting policies and estimates disclosed in our 2025 Annual Report on Form 10-K.
Recently Issued Accounting Pronouncements
A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is set forth in Note 2 "Summary of Significant Accounting Policies" in the Notes to Condensed Consolidated Financial Statements in Part I, Item 1 "Financial Statements" of this Quarterly Report on Form 10-Q.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
We did not have any floating rate debt as of September 30, 2026. Our cash and cash equivalents consist primarily of bank deposits and money market accounts. The primary objective of our investments is the preservation of capital to fulfill liquidity needs. We do not enter into investments for trading or speculative purposes. Due to the short-term nature and low risk profile of these investments, we do not expect cash flows to be affected to any significant degree by a sudden change in market interest rates, including an immediate change of 100 basis points, or one percentage point. Declines in interest rates, however, would reduce future investment income.

Table of Contents
Inflation Risk
We do not believe that inflation has had a material effect on our business, financial condition, or results of operations, other than its impact on the general economy. Nonetheless, to the extent our costs are impacted by general inflationary pressures, including as a result of tariffs, we may not be able to fully offset such higher costs through price increases or manufacturing efficiencies. Our inability or failure to do so could harm our business, financial condition, and results of operations.
Foreign Exchange Risk
We operate our business primarily within the United States and currently execute the majority of our transactions in U.S. dollars. We have not utilized hedging strategies with respect to such foreign exchange exposure. This limited foreign currency translation risk is not expected to have a material impact on our condensed consolidated financial statements.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of the end of the period covered by this Quarterly Report on Form 10-Q.
Disclosure controls and procedures are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, our principal executive officer and principal financial officer, respectively, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2026.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the three months ended September 30, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Table of Contents
A significant portion of our revenue is derived from a limited number of customers, including our Embedded partners, and the loss of, or a significant reduction in revenue from, any of these customers could adversely affect our business, financial condition, and results of operations.
A limited number of customers account for a significant portion of our revenue. For the three months ended September 30, 2026, two customers each accounted for more than 10% of our total revenue. For the nine months ended September 30, 2026, one customer accounted for more than 10% of our total revenue. By comparison, no customer accounted for more than 10% of our total revenue for the three and nine months ended September 30, 2025. As of September 30, 2026, two customers each accounted for more than 10% of our accounts receivable.
We expect that a limited number of customers will continue to account for a significant portion of our revenue for the foreseeable future. Our agreements with these customers may be terminated in certain circumstances, including for certain breaches and insolvency events. Our ability to receive milestone and other contingent payments under these agreements depends on factors outside our control. If any of these customers terminates or fails to renew its agreement with us, delays or fails to make required payments, or experiences financial difficulties, our revenue, cash flows, and results of operations could be materially adversely affected. Our concentration of accounts receivable also exposes us to increased credit risk.
