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 U.S. generally accepted accounting principles (“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 2024 Annual Report on Form 10-K. All intercompany balances and transactions are eliminated upon consolidation.

The condensed consolidated balance sheet as of December 31, 2024, 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 months ended March 31, 2025 are not necessarily indicative of the results to be expected for any subsequent quarter, the year ending December 31, 2025, or any other period.

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 March 31, 2025, substantially all of the Company’s cash and cash equivalents were invested in money market accounts with one financial institution. The Company also maintains balances in various operating accounts above federally insured limits. The Company has not experienced any significant losses on such accounts and does not believe it is exposed to any significant credit risk of its cash and cash equivalents.

As of March 31, 2025 and December 31, 2024, no customer and one customer accounted for more than 10% of the Company’s accounts receivable, respectively. No customer accounted for more than 10% of the Company’s total revenue for the three months ended March 31, 2025 and 2024.

Segment Reporting

The Company has determined that it operates inone 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 ("CEO"), 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):

Other segment items include interest income, interest expense, the change in fair value of warrant liabilities, other income (expense), net, and the provision for income taxes.

Because the Company operates inone 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 consolidated statements of cash flows.

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. There have been no material changes to the Company’s use of estimates as described in the consolidated financial statements for the year ended December 31, 2024.

Operating Expenses – Other

The Company classifies certain operating expenses that are not representative of the Company’s ongoing operations as other on the condensed consolidated statements of operations and comprehensive loss. These include costs related to the Company’s business transformation initiative, reductions in force, litigation, and legal settlements.

The following table summarizes the types of expenses classified as other in the Company’s condensed consolidated statements of operations and comprehensive loss (in thousands):

Recent Accounting Pronouncements Issued but Not Yet Adopted

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which introduced new guidance on disclosures for income taxes, including enhancements to the rate reconciliation and income taxes paid disclosures. This guidance is effective for the Company for annual reporting periods beginning January 1, 2025. 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 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 or 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.

Note 3. Revenue Recognition

Disaggregation of Revenue

The Company disaggregates revenue from contracts with customers by product type and by geographical market. 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 days for sales on credit of product, software, and other services. For the three months ended March 31, 2025 and 2024, the Company recognized $6.4 million and $6.0 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 March 31, 2025 and December 31, 2024, the Company had $41.1 million and $33.3 million, respectively, of remaining performance obligations. As of March 31, 2025, the Company expects to recognize 52% of its remaining performance obligations as revenue in the next twelve months and an additional 48% 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 March 31, 2025 and December 31, 2024.

The Company’s outstanding warrants include 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”). As of March 31, 2025, there were an aggregate of 13,799,357 and 6,853,333 outstanding Public Warrants and Private Warrants, respectively. Each whole warrant entitles the registered holder to purchaseone share of Class A common stock at an exercise price of $11.50 per share, subject to adjustment per the warrant agreements. The warrants will expire on February 12, 2026 or earlier upon redemption or liquidation. 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 months ended March 31, 2025 and 2024.

The Company measures 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 is the same as that of a Public Warrant. Accordingly, the Company measures its Private Warrants using Level 2 fair value inputs based on quoted prices in active markets for the Public Warrants.

The following table summarizes the Company’s assets and liabilities that are measured at fair value on a recurring basis, by level within the fair value hierarchy (in thousands):

Note 5. Inventories

The following table summarizes the Company’s inventories (in thousands):

Work-in-progress represents inventory items in intermediate stages of production by third-party manufacturers. For the three months ended March 31, 2025 and 2024, net realizable value inventory adjustments and excess and obsolete inventory charges were not significant and were recognized in product cost of revenue. See Note 12 “Commitments and Contingencies” for additional information regarding the Company’s inventory supply arrangements.

Note 6. Property and Equipment, Net

The following table summarizes the Company’s property and equipment, net (in thousands):

Note 7. Restricted Cash

The following table reconciles cash, cash equivalents, and restricted cash from the condensed consolidated balance sheets to the condensed consolidated statements of cash flows (in thousands):

Restricted cash included within prepaid expenses and other current assets was restricted by an agreement with the Bill & Melinda Gates Foundation (“Gates Foundation”). As of December 31, 2024, the Company has fulfilled all of its obligations in the agreement, and all of the restrictions on these funds have lapsed. Restricted cash included within other non-current assets is held as collateral to secure a letter of credit for one of our office leases and is expected to be maintained as a security deposit throughout the duration of the lease.

Note 8. Accrued Expenses and Other Current Liabilities

The following table summarizes the Company’s accrued expenses and other current liabilities (in thousands):

The following table summarizes warranty expense activity (in thousands):

The Company classifies its accrued warranty liability based on the timing of expected warranty activity. The future costs of expected activity greater than one year are recorded within other non-current liabilities on the condensed consolidated balance sheets.

Note 9. Stockholders' Equity

Public Share Offering

On January 31, 2025, the Company issued and sold 27,600,000 shares of its Class A common stock in a public offering at a price of $3.15 per share. The Company received gross proceeds of $86.9 million and incurred $5.2 million of underwriting discounts and commissions as well as $0.6 million of other incremental expenses paid by the Company. The net proceeds to the Company, after deducting expenses, was $81.1 million, which has been recognized as increases in cash and cash equivalents and stockholders' equity on the condensed consolidated balance sheets.

Equity Incentive Plans

For the three months ended March 31, 2025, there were no significant changes to the Company’s 2012 Employee, Director and Consultant Equity Incentive Plan, as amended, (the “2012 Plan”) and the Company’s Amended and Restated 2020 Equity Incentive Plan (the “2020 Plan”). On January 1, 2025, pursuant to the terms of the 2020 Plan, the number of shares reserved for issuance was increased automatically by 4% of the number of outstanding shares of common stock as of January 1, 2025.

Stock Option Activity

The following table summarizes the changes in the Company’s outstanding stock options:

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 using similar methods and assumptions as those previously disclosed by the Company.

Restricted Stock Unit Activity

The following table summarizes the changes in the Company’s outstanding restricted stock units (“RSUs”):

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 in 2023 and 2024 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 agreement. 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 risk-free interest rate, expected dividend yield, and expected volatility assumptions as those used by the Company for determining the grant date fair value of its stock options.

Employee Stock Purchase Plan

The Company’s 2024 Employee Stock Purchase Plan (the “ESPP”) was approved by the Board and the Company’s stockholders in the second quarter of 2024, with 4.2 million shares of common stock initially reserved and available for issuance. Under the ESPP, each eligible employee is granted an option to purchase shares of common stock, with the purchase price paid through payroll deductions, subject to the plan’s limitations on the number and value of shares purchasable. Each offering period under the ESPP has an expected duration of 24 months, divided into four six-month purchase periods, with purchases occurring in June and December. The purchase price per share is equal to the lower of 85% of the closing market price on the first day of the offering period, or 85% of the closing market price on the applicable purchase date. Proceeds received from the issuance of shares are credited to stockholders’ equity in the period that the shares are issued. The grant date fair value of the awards is recognized as stock-based compensation expense over the requisite service period. The grant date fair value was determined using similar methods and assumptions as those used for the Company’s stock option awards granted under its equity incentive plans. No shares of common stock have been issued under the ESPP during the three months ended March 31, 2025.

Stock-Based Compensation Expense

The following table summarizes the Company’s stock-based compensation expense (in thousands):

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 year are allocated based on the contractual participation rights of the Class A and Class B common stock as if the earnings for the year had been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis.

The following table summarizes the Company’s anti-dilutive common equivalent shares:

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 March 31, 2025 and 2024, expenses for matching 401(k) contributions were $0.1 million and $0.2 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 March 31, 2025 and 2024, total lease cost was $0.7 million and $0.7 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 quarter of 2021, to pay for a portion of the subsequent inventory purchases using an advance previously paid to the vendor. As of March 31, 2025, the aggregate amount of minimum inventory purchase commitments is $5.6 million, and the Company has a vendor advance asset of $2.7 million, net of write-downs, and an accrued purchase commitment liability of $0.1 million related to the agreement. The portion of the balances that is expected to be utilized in the next 12 months is included in current assets and current liabilities in the accompanying condensed consolidated balance sheets.

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 months ended March 31, 2025 and 2024, 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 months ended March 31, 2025 and 2024, 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, 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 its 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, or traceable to, the Proxy/Registration Statement 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. The Company is unable to predict the outcome or reasonably estimate a range of possible loss at this time.

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, as amended, 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 lawsuit seeks 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.
