NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of Business and Summary of Significant Accounting Policies

Description of Business

Astera Labs, Inc. (the “Company”) offers an Intelligent Connectivity Platform, comprised of semiconductor-based, high-speed, mixed-signal connectivity products that integrate a matrix of microcontrollers and sensors, and COSMOS, the Company’s software suite, which is embedded in its connectivity products and integrated into its customers’ systems.

The Company’s patented software-defined platform approach delivers critical connectivity performance, enables flexibility and customization, and supports observability and predictive analytics. This approach aims to efficiently address the data, network, and memory bottlenecks, scalability, and other unique infrastructure requirements of its hyperscalers and system original equipment manufacturers (“OEMs”) customers.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements and notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the SEC regarding interim financial information. Certain information and disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. The unaudited condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and related notes as of and for the year ended December 31, 2025, included in its Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on February 20, 2026.

In the opinion of management, all adjustments, including normal recurring adjustments, that are considered necessary for a fair presentation of results of operations and financial position, have been included. Operating results for the periods presented herein are not necessarily indicative of the results of operations to be anticipated for the full fiscal year or any future period.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Astera Labs, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Significant Accounting Policies

There have been no material changes in the Company’s significant accounting policies during the three months ended March 31, 2026 compared with the significant accounting policies described in its Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on February 20, 2026.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. The Company’s significant estimates include, but are not limited to, revenue recognition, the valuation of acquired intangible assets, the valuation and realizability of deferred tax assets, reserves for uncertain tax positions, useful life of production equipment, the valuation of warrants, and the valuation and assumptions underlying stock-based compensation. By their nature, estimates are subject to an inherent degree of uncertainty and actual results could differ from those estimates.

The Company assessed certain accounting matters and estimates that generally require consideration of forecasted information available to the Company. Management is not aware of any specific event or circumstance that would require an update to estimates or judgments or a revision to the carrying value of assets or liabilities. These estimates and judgments may change as new events occur and additional information is obtained, which may result in changes being recognized in the Company’s consolidated financial statements in future periods, and actual results could differ from these estimates.

Reclassifications

Certain prior period balances were reclassified to conform to the current period’s presentation. None of these reclassifications had an impact on reported net income, balance sheets, or cash flows for any of the periods presented.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2024, the FASB issued Accounting Standards Update No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosure (“ASU 2024-03”), and in January 2025, the FASB issued Accounting Standard Update No. 2025-01, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosure (Subtopic 2020-40): Clarifying the Effective Date (“ASU 2025-01”). ASU 2024-03 requires additional disclosures of the nature of expenses included in the income statement and disclosures about specific expense categories included in the expense captions presented in the statements of operations. ASU 2024-03, as clarified by ASU 2025-01, is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. Both early adoption and retrospective application are permitted. The Company is currently evaluating the impact that the adoption of these new standards will have on its consolidated financial statements and related disclosures.

In May 2025, the FASB issued Accounting Standards Update No. 2025-04, Compensation-Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Clarifications to Share-Based Consideration Payable to a Customer (“ASU 2025-04”). ASU 2025-04 reduces diversity in practice and improves the decision usefulness and operability of the guidance for share-based consideration payable to a customer in conjunction with selling goods or services. The ASU is effective for annual reporting periods beginning after December 15, 2026 with updates to be applied on a retrospective or modified retrospective basis. Early adoption is permitted. The Company is evaluating the impact that this new standard will have on the Company’s consolidated financial statements and related disclosures.

In September 2025, the FASB issued Accounting Standards Update No. 2025-06, Intangibles - Goodwill and Other -Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). ASU 2025-06 removes all references to project stages throughout Subtopic 350-40 and clarifies the threshold that the entities must meet to begin capitalizing costs. The ASU is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The Company is evaluating the impact that this new standard will have on the Company’s consolidated financial statements and related disclosures.

2. Segment and Geographical Information

The Company’s chief operating decision maker (“CODM”) is its Chief Executive Officer (“CEO”), who reviews financial information presented on a consolidated basis for purposes of making operating decisions, assessing financial performance, and allocating resources. The CODM uses net income to evaluate the return on assets and to determine investment opportunities related to product development, platform enhancements, and new technologies. The CODM also uses net income to monitor budget versus actual results. The Company manages its operations and allocates resources as a single operating segment.

The following table includes the significant expense categories and amounts that are regularly provided to the CODM (in thousands):

(1) Stock-based compensation and personnel-related expenses presented in the above table are related to operating expenses and exclude amounts included in the cost of revenue.

(2) Other segment items included are primarily related to interest income, income tax benefit, engineering design related costs, and professional and consulting services fees.

Revenue by location is determined by the billing address of the Company’s customers, which includes the Company’s end customers’ manufacturing partners and the Company’s distributors.

The following table sets forth revenue by geographic area (in thousands):

The Company had the following customers that individually comprised 10% or more of its revenue:

*Less than 10% of total revenue

Certain of the customers listed above are manufacturing partners that purchase the Company's products on behalf of the Company’s end customers. As end customers may shift production volumes among their manufacturing partners from period to period, the revenue concentration percentages attributable to individual direct customers may fluctuate in a manner that is not necessarily representative of changes in underlying end-customer demand.

The Company had the following customers that individually comprised 10% or more of its accounts receivable, net:

*Less than 10% of total accounts receivable, net

The Company did not recognize any material allowance for credit losses as of March 31, 2026 and December 31, 2025.

Property and equipment, net by geographic location is based on the location of the asset. As of March 31, 2026, 23% and 69% of the Company’s property and equipment, net was located in the United States and Taiwan, respectively. As of December 31, 2025, 20% and 73% of the Company’s property and equipment, net was located in the United States and Taiwan, respectively.

3. Marketable Securities

The amortized cost, gross unrealized gains and losses, and fair value of available-for-sale securities by major security type are as follows (in thousands):

As of March 31, 2026 and December 31, 2025, the Company’s marketable securities that were in a continuous loss position for 12 months or more, as well as the unrealized losses on those marketable securities, were not material. Unrealized losses have not been recognized into income as the Company neither intends to sell, nor anticipates that it is more likely than not that the Company will be required to sell, the securities before recovery of their amortized cost basis. The decline in fair value is due primarily to changes in market interest rates, rather than credit losses.

The contractual maturities of cash equivalents and marketable securities classified as available-for-sale are as follows (in thousands):

Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

The Company did not recognize any material allowance for credit losses as of March 31, 2026 and December 31, 2025 or impairment charges for the three months ended March 31, 2026 and 2025.

There were no material realized gains or losses from available-for-sale securities that were reclassified out of accumulated other comprehensive income for the three months ended March 31, 2026 and 2025.

4. Fair Value Measurements

Fair Value of Assets and Liabilities

The Company considers fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company utilizes the following three-level fair value hierarchy to establish the priorities of the inputs used to measure fair value:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Assets and liabilities valued based on observable market data for similar instruments, such as quoted prices for similar assets or liabilities or other inputs that are observable or can be corroborated by observable market data.

Level 3 — Unobservable inputs reflecting the Company’s assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.

The following table presents information about the Company’s financial assets measured at fair value on a recurring basis based on the fair value hierarchy as follows (in thousands):

As of March 31, 2026 and December 31, 2025, there were no marketable securities with Level 3 fair value hierarchy measurement.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Goodwill, intangible assets, property, plant and equipment, and certain equity investments without readily determinable fair values are not required to be measured at fair value on a recurring basis. However, if the Company is required to evaluate these assets for impairment, whether due to certain triggering events or because of the required annual impairment test, and a resulting impairment is recorded to reduce the carrying value to the fair value, these assets are measured at fair value during such period. There was no impairment on these assets during the three months ended March 31, 2026 and 2025.

As of March 31, 2026 and December 31, 2025, the Company had no liabilities required to be measured at fair value on a nonrecurring basis.

Assets and Liabilities Not Measured at Fair Value

The carrying amount of the Company’s financial instruments, including cash equivalents, accounts receivable, and accounts payable, approximates their respective fair values because of their short maturities.

5. Condensed Consolidated Balance Sheet Components

Inventory

Inventory consists of the following (in thousands):

Property and Equipment, Net

Property and equipment, net consists of the following (in thousands):

Depreciation and amortization expense for the three months ended March 31, 2026 and 2025 was $3.7 million and $1.1 million, respectively.

6. Business Combinations

On February 9, 2026, the Company acquired certain assets of a privately held company that develops data center acceleration solutions designed to make data storage and processing faster, more efficient, and more cost-effective. In connection with the acquisition, the Company added highly skilled workforce and technology to enable development of its products and solutions. The total purchase consideration was $74.0 million, which consisted of $65.0 million in cash, $5.0 million in holdback for general indemnities, and $4.0 million in share-based consideration. The transaction has been accounted for as a business combination.

The purchase price was allocated on a preliminary basis to goodwill of $68.4 million and an immaterial amount to intangible assets and net identifiable assets acquired. Goodwill primarily relates to expected synergies and assembled workforce and is not deductible for U.S. federal income tax purposes.

Additional information related to the acquisition, such as that related to income tax and other contingencies, existing as of the acquisition date may become known during the remainder of the measurement period, not to exceed 12 months from the acquisition date, which may result in changes to the amounts and allocations recorded.

During the three months ended March 31, 2026, the Company had immaterial measurement period adjustments to goodwill.

7. Leases

The Company has entered into operating leases primarily for office real estate in the United States and internationally. From time to time, the Company entered into a new leases and renewed existing leases in the ordinary course of business to support its ongoing operations and growth. The Company’s lease payments consist primarily of fixed rental payments for the right to use the underlying leased assets over the lease terms for all leases.

Supplemental balance sheet information related to the Company’s operating leases is as follows (in thousands):

Operating lease ROU assets, net are included in other assets; operating lease liabilities, current are included in accrued expenses and other current liabilities; and operating lease liabilities, non-current are included in other liabilities, on the condensed consolidated balance sheets.

The weighted-average remaining lease term and discount rates were as follows:

The future minimum operating lease payments for each of the next five years and thereafter are as follows (in thousands):

As of March 31, 2026, the Company had entered into lease agreements associated with the exercise of an existing expansion option at its headquarters in San Jose, California. These agreements result in total estimated future undiscounted lease obligations of $14.8 million. The lease terms are expected to commence at various dates between April 2026 and March 2027 and will expire in November 2032.

8. Commitments and Contingencies

Purchase Commitments

The Company depends upon third-party subcontractors to manufacture wafers and other inventory parts or to perform certain services. The Company’s subcontractor relationships typically allow for the cancellation of outstanding purchase orders but require payment of all expenses incurred through the date of cancellation. The Company’s purchase commitments also include payments for software licenses and cloud services when there is a fixed, non-cancellable payment schedule or when minimum payments are due according to a delivery schedule. The Company is committed to make the following minimum payments under its purchase commitments as of March 31, 2026 (in thousands):

Legal Proceedings

From time to time, the Company may become subject to legal proceedings, claims and litigation arising in the ordinary course of business. The Company is not currently a party to any material legal proceedings or claims, nor is the Company aware of any other pending or threatened legal proceedings or claims that could reasonably be expected to have a material adverse effect on the Company’s business, operating results, cash flows or financial condition should such legal proceedings or claims be resolved unfavorably.

Indemnification Obligations

In the ordinary course of business, the Company often includes standard indemnification provisions in its arrangements with its members, partners, suppliers and vendors. Pursuant to these provisions, the Company may be obligated to indemnify such parties for losses or claims suffered or incurred in connection with its service, breach of representations or covenants, intellectual property infringement or other claims made against such parties. These provisions may limit the time within which an indemnification claim can be made. It is not possible to determine the maximum potential amount under these indemnification obligations due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. The Company has not in the past incurred significant expense defending its licensees against third party claims, nor has it incurred significant expense under its standard service warranties or arrangements with its members, partners, suppliers, and vendors. Accordingly, the Company had no liabilities recorded for these provisions as of March 31, 2026 and December 31, 2025.

9. Common Stock Warrants

In October 2022, the Company issued a warrant to a customer (“Holder”) to purchase an aggregate of up to 1,484,230 shares of Common Stock (the “Customer Warrant”). The exercise period of the Customer Warrant is through the seventh anniversary of the issue date.

In October 2023, the Company amended the Customer Warrant and issued an additional warrant to the Holder to purchase an aggregate of up to 831,945 shares of Common Stock (the “2023 Warrant”), with the same exercise period as the Customer Warrant. The 2023 Warrant will vest and become exercisable over the contract term, contingent upon the achievement of performance conditions, comprised of specified tranches of purchases by the Holder and its affiliates to the Company.

In February 2026, the Company issued a warrant to the Holder to acquire up to an aggregate of 3,262,299 shares of common stock at an exercise price of $142.82 per share (the “2026 Warrant”, and together with the Customer Warrant and the 2023 Warrant, the “Warrants”). The 2026 Warrant will vest and become exercisable over the contract term, contingent upon the achievement of performance conditions, comprised of specified tranches of purchases by the Holder and its affiliates to the Company.

The grant date fair value of the 2026 Warrant were determined to be $85.83 per share, using the Black-Scholes-

Merton option pricing model, for maximum total 2026 Warrant fair value of $280.0 million. The per share grant date fair values of the 2026 Warrant were estimated using the following assumptions:

As of March 31, 2026 and December 31, 2025, an aggregate of 1,331,902 shares and 1,165,513 shares, respectively, of the underlying Warrants were vested and exercisable. Additionally, an aggregate of 73,085 and 30,589 shares were probable of vesting as of March 31, 2026 and December 31, 2025, respectively. There were no warrant exercises as of March 31, 2026.

The Company recognized $2.1 million and $0.4 million for the three months ended March 31, 2026 and 2025, respectively, as a reduction of revenue in the condensed consolidated statements of operations and comprehensive income related to the Warrants. The remaining grant date fair values of the Warrants that are probable of vesting will be recognized as a reduction of revenue in proportion to the amount of related product sales, which could occur until January 2, 2033.

10. Stock-Based Compensation

A summary of stock-based compensation expense recognized in the condensed consolidated statements of operations and comprehensive income is as follows (in thousands):

(1) Stock-based compensation expense for the three months ended March 31, 2026 did not include the $4.0 million in share-based consideration related to acquisitions, see Note 6 - Business Combinations for further details.

Stock Options

A summary of stock option activity under the 2018 Plan and 2024 Plan is as follows (in thousands, except years and per share data):

As of March 31, 2026, there was approximately $0.6 million of total unrecognized compensation cost, related to unvested stock options, which is expected to be recognized over a weighted-average remaining requisite service period of 1.3 years, using the straight-line method.

Restricted Stock Units (“RSUs”)

A summary of RSU activity under the 2018 Plan and 2024 Plan is as follows (in thousands, except per share data):

As of March 31, 2026, there was $457.6 million of unrecognized stock-based compensation expense related to unvested RSUs, which is expected to be recognized over a weighted-average period of 1.9 years.

Performance Stock Units (“PSUs”)

A summary of PSU activity under the 2024 Plan is as follows (in thousands, except per share data):

As of March 31, 2026, there was $43.1 million of unrecognized stock-based compensation expense related to these PSUs, which is expected to be recognized over a weighted-average period of 2.4 years.

11. Net Income per Common Share

The following table sets forth the computation of basic and diluted net income per share attributable to the Company’s common stockholders (in thousands, except per share data):

Potentially dilutive securities include dilutive common stock from assumed exercise of stock options, RSUs, Warrants, and Employee Stock Purchase Plan shares using the treasury stock method. Under the treasury stock method, potential shares outstanding are not included in the computation of diluted net income per share if their effect is anti-dilutive. Anti-dilutive potential shares are as follows (in thousands):

12. Income Taxes

The Company's income tax benefit recognized for the three months ended March 31, 2026 and 2025 is as follows (in thousands, except percentages):

On July 4, 2025, the One Big Beautiful Bill Act (the "Act") was signed into law. The legislation includes a broad range of tax reform provisions affecting businesses including, but not limited to, the reinstatement of 100% bonus depreciation, immediate expensing of domestic research and development costs, and revisions to the U.S. taxation of profits derived from international operations. The legislation has multiple effective dates, with certain provisions were effective in 2025 and others becoming effective through 2027. The Company has assessed the effects of the new tax legislation, including immediate expensing of domestic research and development expenditures and revisions to foreign-derived intangible income provision for the calendar year, and the results have been reflected in its condensed consolidated financial statements for the three months ended March 31, 2026.

The Company accrues for income taxes during interim periods based on the estimated effective tax rate for the year. The effective tax rate for the three months ended March 31, 2026 is different than the statutory federal tax rate primarily due to the valuation allowance in the United States and the excess tax benefits related to equity compensation, foreign derived intangible income deduction and U.S. research and development credits, which results in current tax benefits. The determination of the realizability of deferred tax assets requires significant judgment in assessing if there is sufficient positive evidence to support a conclusion that it is more likely than not the deferred tax assets will be realized. If the Company continues to achieve positive operating results, it may release the valuation allowance associated with its U.S. deferred tax assets in future periods. A release of all, or a portion, of the valuation allowance would result in the recognition of certain deferred tax assets and may result in a material decrease to income tax expense for the period the release is recorded.

The effective tax rate for the three months ended March 31, 2025 is different than the statutory federal tax rate primarily due to the valuation allowance in the United States and the excess tax benefits related to equity compensation, foreign derived intangible income deduction and U.S. research and development credits, which results in current tax benefit. This is offset by the current tax expense from the capitalization of research and development expenditures under Section 174 of the Internal Revenue Code.

Results of Operations

Comparison of the Three Months Ended March 31, 2026 and 2025

Revenue

Total revenue increased $148.9 million, or 93%, for the three months ended March 31, 2026, compared to the same period in 2025, primarily due to an increase in overall unit shipments driven by higher demand for our Scorpio, Aries, and Taurus products, as well as higher overall average selling prices resulting from an increased mix of hardware modules and Scorpio products.

Cost of Revenue, Gross Profit, and Gross Margin

Total cost of revenue increased $33.2 million, or 83%, for the three months ended March 31, 2026, compared to the same period in 2025, primarily due to higher overall unit shipments and a favorable shift in product mix.

Gross margin increased 136 bps to 76.3% for the three months ended March 31, 2026 compared to 74.9% for the same period in 2025. The increase was primarily driven by a favorable product mix.

Research and Development

Research and development expense increased $61.1 million, or 95%, for the three months ended March 31, 2026 compared to the same period in 2025. The increase was primarily due to a $29.3 million increase in overall spending to support our R&D initiatives, which includes hardware design, software license, and cloud hosting services costs, a $17.1 million increase in personnel-related costs and $10.2 million of non-cash stock-based compensation expenses resulting from a 90% increase in headcount, and $3.1 million increase in other operating costs to support our business expansion.

Sales and Marketing

Sales and marketing expense increased by $0.2 million, or 1%, for the three months ended March 31, 2026 compared to the same period in 2025. The increase was primarily due to a $2.0 million increase in personnel-related costs resulting from a 55% increase in headcount and $0.3 million in other operating costs to support our business expansion, partially offset by a $2.4 million decrease in non-cash stock-based compensation expenses.

General and Administrative

General and administrative expense increased $3.9 million, or 18%, for the three months ended March 31, 2026 compared to the same period in 2025. The increase was primarily due to a $2.5 million increase in professional services fees associated with the continued development of our public company infrastructure, a $1.8 million increase in personnel-related costs resulting from a 57% increase in headcount, a $1.5 million increase in other operating costs to support our business expansion. The increase was partially offset by a $1.9 million decrease in non-cash stock-based compensation expenses.

Interest Income

For the three months ended March 31, 2026, interest income increased $1.1 million, or 11%, compared to the same period in 2025, primarily due to higher average balances of short-term investments and cash equivalents as a result of cash flow from operations.

Income Tax Benefit

The benefit from income tax decreased $3.2 million, or 32%, for the three months ended March 31, 2026 compared to the same period in 2025, primarily due to a decrease in excess tax benefits related to equity compensation.

Non-GAAP Financial Measures

This Quarterly Report on Form 10-Q contains certain financial measures that are not presented in accordance with generally accepted accounting principles in the United States (“GAAP”), which we use to supplement the performance measures in our condensed consolidated financial statements, which are presented in accordance with GAAP. We refer to these measures as “non-GAAP financial measures.” These non-GAAP financial measures include non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income, and non-GAAP net income. We use these non-GAAP financial measures for financial and operational decision-making and as a means to assist us in evaluating period-to-period comparisons. By excluding certain items that may not be indicative of our recurring core operating results, we believe that non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income, and non-GAAP net income provide meaningful supplemental information regarding our performance. Accordingly, we believe these non-GAAP financial measures are useful to investors and others because they allow for additional information with respect to financial measures used by management in its financial and operational decision-making and they may be used by our institutional investors and the analyst community to help them analyze the health of our business. However, there are a number of limitations related to the use of non-GAAP financial measures, and these non-GAAP measures should be considered in addition to, not as a substitute for or in isolation from, our financial results prepared in accordance with GAAP. Other companies, including companies in our industry, may calculate these non-GAAP financial measures differently or not at all, which reduces their usefulness as comparative measures.

Non-GAAP Gross Profit and Non-GAAP Gross Margin

We define non-GAAP gross profit as gross profit presented in accordance with GAAP, adjusted to exclude non-cash stock-based compensation expenses. The non-GAAP gross margin is non-GAAP gross profit divided by revenue. We have presented non-GAAP gross profit because we consider non-GAAP gross profit to be a useful metric for investors and other users of our financial information in evaluating our operating performance as it excludes the impact of non-cash stock-based compensation, a charge that can vary from period to period for reasons that are unrelated to our core operating performance. This metric also provides investors and other users of our financial information with an additional tool to eliminate the effects of items that may vary for different companies for reasons unrelated to core operating performance.

A reconciliation of our GAAP gross profit and GAAP gross margin, the most directly comparable GAAP financial measures, to non-GAAP gross profit and non-GAAP gross margin is presented below:

(1) Total may not sum due to rounding.

Non-GAAP Operating Income and Non-GAAP Operating Margin

We define non-GAAP operating income as operating income presented in accordance with GAAP, adjusted to exclude non-cash stock-based compensation expenses and acquisition-related costs. We define non-GAAP operating margin as non-GAAP operating income divided by revenue. We have presented non-GAAP operating income and non-GAAP operating margin because we consider them useful metrics for investors and other users of our financial information in evaluating our operating performance as it excludes the impact of non-cash stock-based compensation expense and acquisition-related costs, a charge that can vary from period to period or are one time charges for reasons that are unrelated to our core operating performance. These metrics also provide investors and other users of our financial information with an additional tool to eliminate the effects of items that may vary for different companies for reasons unrelated to core operating performance.

A reconciliation of our GAAP operating income and GAAP operating margin, the most directly comparable GAAP financial measures, to non-GAAP operating income and non-GAAP operating margin is presented below:

(1) Acquisition-related costs include certain incremental expenses incurred to effect a business combination such as third-party costs: advisory, legal, accounting, valuation, and other professional fees.

(2) Total may not sum due to rounding.

Non-GAAP Net Income

We monitor non-GAAP net income for planning and performance measurement purposes. We define non-GAAP net income as net income presented in accordance with GAAP on our condensed consolidated statements of operations,

excluding the impact of non-cash stock-based compensation expenses, acquisition-related costs, and the related tax impact on the adjustments. We have presented non-GAAP net income because we believe that the exclusion of these charges allows for a more relevant comparison of our results of operations to other companies in our industry and facilitates period-to-period comparisons as it eliminates the effect of certain factors unrelated to our overall operating performance.

A reconciliation of our GAAP net income, the most directly comparable GAAP financial measure, to our non-GAAP net income is presented below:

(1) Acquisition-related costs include certain incremental expenses incurred to effect a business combination such as third-party costs: advisory, legal, accounting, valuation, and other professional fees.

(2) Income tax effect is calculated based on the tax laws in the jurisdictions in which we operate and is calculated to exclude the impact of non-cash stock-based compensation expense and one-off discrete tax adjustments that are unrelated to our core operating performance. We no longer maintain valuation allowance for non-GAAP purposes due to our cumulative tax profits on a non-GAAP basis. For the three months ended March 31, 2026 and 2025, the non-GAAP tax rate was approximately 11% and 7%, respectively.

Liquidity and Capital Resources

Since our inception, we have financed our operations primarily through proceeds from equity issuances including net proceeds from our IPO, and cash generated from the sale of our products. As of March 31, 2026, our principal sources of liquidity were cash, cash equivalents, and marketable securities of $1.2 billion. Our principal use of cash is to fund our operations, invest in research and development, fund capital expenditures for production equipment, acquisitions of businesses or technologies, and to support our overall growth.

We generated $74.6 million in cash flow from operating activities for the three months ended March 31, 2026 and a retained earnings of $90.6 million as of March 31, 2026. We believe that our current cash, cash equivalents, and marketable securities will be sufficient to fund our operations for at least the next 12 months and beyond. Our future capital requirements, however, will depend on many factors, including our growth rate, the timing and extent of our sales and marketing and research and development expenditures, capital expenditures for production equipment, the continuing market acceptance of our products, and the use of cash to fund potential mergers or acquisitions. In the event that additional financing is required from outside sources, we may seek to raise additional funds through equity, equity-linked arrangements, and debt. If we are unable to raise additional capital when desired and at reasonable rates, our business, results of operations, and financial condition could be adversely affected.

Cash Flows

The following table summarizes our cash flows for the periods presented:

Change in Cash Flows from Operating Activities

Net cash provided by operating activities for the three months ended March 31, 2026 was $74.6 million, compared to $10.5 million for the comparable period in 2025. The $64.1 million increase in operating cash inflows was a result of a $48.5 million increase in net income, higher non-cash charges of $12.3 million, and a favorable change of $3.3 million from changes in operating assets and liabilities. The higher non-cash charges of $12.3 million were primarily due to a $6.5 million increase in stock-based compensation expense, $2.6 million increase in depreciation and amortization, a $1.7 million increase in warrants contra revenue, and $1.3 million increase in accretion of discounts on marketable securities. The favorable change of $3.3 million in operating assets and liabilities was predominantly attributable to a $28.4 million favorable change in the prepaid expenses and other assets, and a $7.1 million favorable change in inventory. The favorable change was partially offset by (i) a $20.8 million unfavorable changes in accounts receivable due to higher product sales and the timing of customer payments, and (ii) a $11.4 million unfavorable change in accounts payables and accrued other liabilities primarily due to the timing of payments.

Change in Cash Flows from Investing Activities

Net cash used in investing activities for the three months ended March 31, 2026 was $94.0 million, compared to $3.9 million for the comparable period in 2025. The $90.1 million increase in cash used in investing activities was primarily due to a $65.0 million increase associated with the acquisition of a business, a $53.7 million decrease in proceeds from sales and maturities of marketable securities, and a $3.0 million increase in proceeds used in purchase of property and equipment, partially offset by a $34.2 million decrease in purchases of marketable securities.

Change in Cash Flows from Financing Activities

Net cash provided by financing activities for the three months ended March 31, 2026 was $0.1 million, compared to $0.4 million for the comparable period in 2025. The $0.3 million decrease in cash provided by financing activities was primarily due to a decrease related to proceeds received from exercises of stock options.

Critical Accounting Estimates

Our unaudited condensed consolidated financial statements and the related notes thereto included elsewhere in this Quarterly Report on Form 10-Q are prepared in accordance with GAAP. The preparation of unaudited condensed consolidated financial statements in accordance with GAAP requires us to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and the related disclosures as of the date of the financial statements, as well as the reported amounts of revenue and expenses during the period presented. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from our estimates. To the extent that there are differences between our estimates and actual

results, our future financial statement presentation, financial condition, results of operations, and cash flows could be affected.

There have been no material changes to our critical accounting policies and estimates as described in our Annual Report on Form 10-K for the year ended December 31, 2025.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest rate risk and foreign currency exchange risk are described in Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk” in our Annual Report on Form 10-K for the year ended December 31, 2025. As of March 31, 2026, there have been no material changes to the interest rate and foreign currency exchange risk described as of December 31, 2025.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Our disclosure controls and procedures are designed to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of March 31, 2026, our disclosure controls and procedures were effective at a reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

A control system, no matter how well designed and operated, can provide only reasonable, not absolute assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls.

Part II - Other Information

Item 1. Legal Proceedings

We are not currently a party to any material pending legal proceedings. From time to time, we may be subject to legal proceedings and claims arising in the ordinary course of business. The results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

We caution you that the foregoing list may not contain all of the forward-looking statements made in this Quarterly Report on Form 10‑Q. You should not rely upon forward-looking statements as predictions of future events.

We have based the forward-looking statements contained in this Quarterly Report on Form 10-Q primarily on management’s current beliefs and our current expectations and projections about future events and trends that we believe may affect our business, results of operations, financial condition, and prospects. In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report on Form 10‑Q, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information.

New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this Quarterly Report on Form 10-Q. The results, events, and circumstances reflected in the forward-looking statements may not be achieved or occur, and actual results, events, or circumstances could differ materially from those described in the forward-looking statements.

The forward-looking statements made in this Quarterly Report on Form 10‑Q relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made in this Quarterly Report on Form 10‑Q to reflect events or circumstances after the date of this Quarterly Report on Form 10‑Q or to reflect new information or the occurrence of unanticipated events, except as required by law.
