Recent Developments

On May 16, 2025, pursuant to a definitive agreement and plan of merger (Mobius Agreement), the Company acquired all of the outstanding equity interests in Mobius Therapeutics, LLC (Mobius) for $12.4 million, net of cash acquired (Mobius Merger). Pursuant to the Mobius Agreement, the Company also agreed to pay the former Mobius equityholders contingent consideration in the form of single-digit royalty payments based on net sales of Mobius products for a period offour years, and additional, potential performance-based payments of up to $80.0 million in aggregate upon the achievement of certain net sales milestones with respect to such Mobius products. See Note 6.Business Combinations for additional details.

On April 4, 2025, the Company purchased certain real property consisting of an approximately 40,000 square foot, two-story building, located in Aliso Viejo, California (Aliso Building) and which is adjacent to the Company’s Aliso Viejo, California headquarters (Aliso Facility). The Company paid a purchase price of $16.6 million for the Aliso

Building, which is currently occupied by several tenants whose leases, which were assumed by the Company, expire at various times over the next four years. See Note 5.Real Estate Acquisitions and Leases for additional details.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates and assumptions used in the preparation of the accompanying condensed consolidated financial statements under different assumptions and conditions.

The Company’s condensed consolidated financial statements as of and for the three and nine months ended September 30, 2025 reflect the Company’s estimates of the impact of the macroeconomic environment, including the impact of inflation, supply shortages or delays, changes in supply and demand, foreign exchange rate fluctuations and other conditions which have led to disruptions in commerce and pricing stability. The Company is not aware of any specific event or circumstance that would require an update to its estimates, judgments and assumptions or a revision of the carrying value of the Company’s assets or liabilities as of September 30, 2025.

Cash, Cash Equivalents and Restricted Cash

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the condensed consolidated balance sheets that equate to the amount reported in the condensed consolidated statements of cash flows as of the beginning and end of nine months ended September 30, 2025 (in thousands):

The Company’s cash and cash equivalents include cash in readily available checking and money market accounts, as well as certificates of deposit. The Company maintains balances of cash and cash equivalents at one or more financial institutions that are in excess of federally insured limits.

Recently Adopted Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-09,Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to improve the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid by jurisdiction. The ASU is effective for public business entities’ annual periods beginning after December 15, 2024, with early adoption permitted. The Company adopted this pronouncement and is evaluating the impact it will have on its upcoming annual filing on Form 10-K for the year ending December 31, 2025; however the Company currently does not believe the adoption will have a material impact on its consolidated financial statements and disclosures for that Form 10-K filing.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2024, the FASB issued ASU No. 2024-03Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires disaggregated disclosure of certain costs and expenses on an interim and annual basis. ASU No. 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The disclosure updates are required to be applied prospectively with the option for retrospective application. The Company is currently evaluating the impact of adopting ASU No. 2024-03 on its condensed consolidated financial statements.

Note 3. Balance Sheet Details

Short-term Investments

Short-term investments consisted of the following (in thousands):

At each reporting date, the Company performs an evaluation of impairment to determine if any unrealized losses are the result of credit losses. Impairment is assessed at the individual security level. Factors considered in determining whether a loss resulted from a credit loss or other factors include the Company’s intent and ability to hold the investment until the recovery of its amortized cost basis, the extent to which the fair value is less than the amortized cost basis, the length of time and extent to which fair value has been less than the cost basis, the financial condition of the issuer, any historical failure of the issuer to make scheduled interest or principal payments, any changes to the rating of the security by a rating agency, any adverse legal or regulatory events affecting the issuer or issuer’s industry, and any significant deterioration in economic conditions.

The credit-related portion of unrealized losses, and any subsequent improvements, are recorded in interest expense in the condensed consolidated statements of operations through an allowance for credit losses. Unrealized gains and losses that are not credit-related are included in accumulated other comprehensive loss. Unrealized losses on available-for-sale debt securities as of September 30, 2025 and December 31, 2024 were not significant and were primarily due to changes in interest rates, including market credit spreads, and not due to increased credit risks associated with specific securities. Further, the Company does not intend to sell these investments prior to maturity and it is not more likely than not that the Company will be required to sell these investments before recovery of their amortized cost basis. Accordingly, the Company did not record an allowance for credit losses with these investments as of September 30, 2025 and December 31, 2024.

Accounts Receivable, Net

Accounts receivable consisted of the following (in thousands):

Accounts receivable, net increased as of September 30, 2025 compared to December 31, 2024 primarily due to an increased proportion of net sales fromiDose TR during 2025 giveniDose TR has extended payment terms and higher net sales price per unit than the Company’s other products. The Company’s allowance for credit losses represents

management’s estimate of current expected credit losses related to customer receivables. Bad-debt write offs charged during the nine months ended September 30, 2025 were not significant.

Additionally, no singular customer accounted for more than 10% of net accounts receivable as of September 30, 2025 or December 31, 2024.

Inventory

Inventory consisted of the following (in thousands):

Accrued Liabilities

Accrued liabilities consisted of the following (in thousands):

Note 4. Fair Value Measurements

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.

The carrying amounts of cash equivalents, accounts receivable, accounts payable, and accrued liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments.

The valuation of assets and liabilities is subject to fair value measurements using a three-tiered approach and fair value measurements are classified and disclosed by the Company in one of the following three categories:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

The following tables present information about the Company’s financial assets and liabilities measured at fair value on a recurring basis as of September 30, 2025 and December 31, 2024 and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value (in thousands):

Money market funds are highly-liquid investments and are actively traded. The pricing information on these investment instruments is readily available and can be independently validated as of the measurement date. This approach results in the classification of these securities as Level 1 of the fair value hierarchy.

U.S. government agency bonds, U.S. treasury securities, bank certificates of deposit, commercial paper, municipal bonds, corporate notes and asset-backed securities are measured at fair value using Level 2 inputs. The Company reviews trading activity and pricing for these investments as of each measurement date. Pursuant to the Company’s deferred compensation plan (the Deferred Compensation Plan), the Company has also established a rabbi trust that serves as an investment to shadow the Deferred Compensation Plan liability. The investments of the rabbi trust and Deferred Compensation Plan liability consist of company-owned life insurance policies (COLIs) and the pricing on these investments can be independently evaluated. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities obtained from third party data providers. These inputs represent quoted prices for similar assets in active markets or these inputs have been derived from observable market data. This approach results in the classification of these securities as Level 2 of the fair value hierarchy.

The Company’s acquisitions may include contingent consideration as part of the purchase price. The fair value of the contingent consideration is estimated as of the acquisition date based on significant inputs not observable in the market, which include the present value of the contingent payments to be made using a Monte Carlo simulation model, computation of net sales volatility, discount rates derived using internal rate of return analysis, the probability and timing of achieving certain future milestones, and to a lesser extent, Glaukos’ credit rating. Contingent consideration represents a Level 3 measurement within the fair value hierarchy. The valuation of contingent consideration uses assumptions the Company believes a market participant would make. The Company assesses these estimates on an ongoing basis as it obtains additional data impacting the assumptions. Should actual results increase or decrease as compared to the assumptions used in the analysis, the fair value of the contingent consideration obligations will increase or decrease, up to the contracted limit, as applicable. Any changes in the fair value of contingent consideration related to updated assumptions and estimates are recognized within other income (expense), net in the condensed consolidated statements of operations. As of September 30, 2025 and December 31, 2024 the contingent

consideration liability was $9.1 million and $1.6 million, respectively. As of September 30, 2025, the balance included the contingent consideration liability related to the Mobius Agreement.

There wereno transfers between levels within the fair value hierarchy during the periods presented.

Note 5. Real Estate Acquisitions and Leases

Real Estate Acquisitions

On April 4, 2025, the Company completed the acquisition of the Aliso Building, consisting of land, buildings and assumed leases, for a total purchase price of approximately $16.6 million. Upon closing, the Company assumed sellers’ interest, as lessor, infour existing leases with a weighted-average remaining term oftwo years, exclusive of certain tenant renewal options.

The Company accounted for the purchase as an asset acquisition and allocated the purchase price to land, building, and identified intangible assets and liabilities, based in each case on their relative estimated fair values and without giving rise to goodwill. Intangible assets and liabilities represent the value of in-place leases and below-market leases. In making estimates of fair values, the Company used various sources, including data provided by independent third parties, as well as information obtained by the Company as a result of its due diligence, including expected future cash flows of the property and various characteristics of the markets where the property is located.

In allocating the fair value of the identified tangible and intangible assets and liabilities of the acquired property, land is valued based upon comparable market data or independent appraisals. Buildings are valued on an as-if vacant basis based on a cost approach utilizing estimates of cost and the economic age of the building or an income approach utilizing various market data. In-place lease intangibles are valued based on the Company’s estimates of costs related to tenant acquisition and the carrying costs that would be incurred during the time it would take to locate a tenant if the property were vacant, considering current market conditions and costs to execute similar leases at the time of the acquisition.

The following table presents the details of the tangible assets acquired and intangible lease liabilities assumed:

Land, buildings, site improvements and tenant improvements are recorded and stated at cost and, except for land, are amortized using the straight-line method over the estimated remaining useful life of the assets, which is 30.0 years for the building,20.0 years for site improvements and an average of approximately 2.2 years for tenant improvements.

The lease income and related lease expense associated with thefour aforementioned leases are recorded within other (expense) income, net within the accompanying condensed consolidated statements of operations and is not

significant during the three months ended September 30, 2025 and will not be material for the full year ending December 31, 2025.

Leases

The Company has operating and finance leases for facilities and certain equipment. Leases with an initial term of 12 months or less are expensed and not recorded on the condensed consolidated balance sheet. Lease expense for operating leases is recognized on a straight-line basis over the lease term.

The Company’s leases have non-cancelable lease terms of approximatelyone year tothirteen years, some of which include options toextend the leases for up toten years. The exercise of lease renewal options is at the Company’s sole discretion. In certain of the Company’s lease agreements, the rental payments are adjusted periodically to reflect actual charges incurred for common area maintenance, landlord incentives and/or inflation.

The Company’s Aliso Facility isone property containing three existing office buildings, comprising approximately 160,000 rentable square feet of space, and which is accounted for as a finance lease. The term of the Aliso Facility commenced on April 1, 2019 for expense recognition and continues forthirteen years. The lease agreement contains an option to extend the lease fortwo additional five year periods at market rates.

The Company also leasestwo adjacent buildings, two office suites and a warehouse located in San Clemente, California and a facility in Burlington, Massachusetts. The total leased square footage of the San Clemente facilities equals approximately 120,000 and thetwo most significant leases now expire on May 31, 2035, after executing afive-year extension from the previous May 31, 2030 expiration date, during the first quarter of 2025. Each of thesetwo leases contain an option toextend the lease forone additional five-year period at market rates. The total leased square footage of the Burlington facility is approximately 60,000 square feet, and the lease expires on July 31, 2033. The Burlington facility lease contains an option to extend the lease forone additional five-year period at market rates.

The Company’s remaining foreign subsidiaries’ leased office and warehouse space totals less than 35,000 square feet.

The following table presents the maturity of the Company’s operating and finance lease liabilities within the condensed consolidated balance sheets:

Note 6. Business Combinations

The Mobius acquisition is intended to expand the Company's portfolio of pharmaceutical products related to the treatment of glaucoma, as the lead Mobius product isMitosol, the only FDA-approved ophthalmic formulation of mitomycin-C, which is often utilized as an adjunct in late-stage glaucoma filtration procedures.

The combined fair value of the consideration transferred at closing was $24.5 million (the Merger Consideration), that consisted of the following (in thousands):

The contingent consideration represents the fair value of: (i) potential future net sales-based milestone payments up to $80.0 million based on predetermined measurement periods, and are conditional based on achieving contractually specified net sales thresholds for the Mobius products for the calendar years ending December 31, 2025 through December 31, 2030, and; (ii) future single digit percentage royalty payments based on net sales of the Mobius products to be made for calendar years ending December 31, 2025 through December 31, 2030. As of September 30, 2025, $7.1 million of the contingent consideration liability is included in other liabilities and $0.6 million is included in accrued liabilities in the condensed consolidated balance sheets.

The Company performed a valuation analysis of the fair market value of Mobius’s assets and liabilities as of closing. The following table sets forth an allocation of the Merger Consideration to the identifiable tangible and intangible assets acquired and liabilities assumed, with the excess recorded to goodwill. The allocation of the Merger Consideration as of May 16, 2025 was as follows (in thousands):

Goodwill represents the excess of the Merger Consideration over the preliminary fair value of the underlying assets acquired and liabilities assumed. Goodwill is attributable to the assembled workforce, intellectual property, and established processes at Mobius and expected synergies. The transaction is considered an asset acquisition for tax purposes. As such, goodwill will be deductible once the contingent consideration is paid, consistent with the tax treatment of asset acquisitions.

The fair value and estimated useful lives of the Mobius intangible assets acquired are as follows (in thousands, except where noted):

Note 7. Intangible Assets and Goodwill

Intangible assets

As part of the Mobius Merger, the Company acquired identifiable intangible assets for (i) developed technology related to Mitosol, an ophthalmic formulation of mitomyacin-C, which is often used as an adjunct in late-stage glaucoma filtration procedures, which will be amortized to cost of sales over a weighted-average estimated useful life of approximately 9 years, and (ii) customer relationships, which will be amortized to selling, general and administrative expense over an estimated useful life of 9 years.

The fair value of developed technology and customer relationships assets were determined using an excess earnings methodology. Significant assumptions used in the valuations include: (i) the period in which material net cash inflows are expected to commence, which was estimated to be 2025 for both the developed technology and customer relationships, and (ii) the period in which the present value of cash inflows are expected to become immaterial, which was estimated to be 2054 for developed technology and 2044 for the customer relationships, and (iii) the discount rate of 41.0% for both the developed technology and customer relationships.

Effective March 17, 2023, the Company entered into a sales agreement (Sales Agreement) with Celanese Canada ULC (Celanese) under which Celanese will make available and supply to the Company certain raw materials used to create a nanoporous membrane utilized in theiDose TR, and authorized the Company to reference its Drug Master File (DMF) with respect to such raw materials, which is required for the Company to commercializeiDose TR. The term of the Sales Agreement isfour years after theiDose TR launch date in February 2024. In exchange for the ability to obtain future raw materials and the rights related to the DMF, the Company is subject to minimum compensation payments over four years of $6.3 million and potential additional royalties based on a percentage of sales of theiDose TR product. The Company recognized an intangible asset related to the minimum compensation payments at fair value of $5.2 million upon the date of acquisition, which was determined to be theiDose TR launch date. As of September 30, 2025, the remaining balance of $4.9 million is included in Intangible assets, net on the condensed consolidated balance sheets and will continue to be amortized to cost of sales over its useful life offour years, which is the initial term of the Sales Agreement. A member of the Celanese board of directors also sits on the board of directors of the Company.

The Company evaluated its indefinite-lived intangible assets for impairment and concluded there were no indicators of impairment as of September 30, 2025.

Goodwill

The assessment of goodwill by reporting unit is performed annually, in the fourth quarter, or more frequently if events or circumstances indicate the carrying value may no longer be recoverable and that an impairment loss may have occurred. The Company considered the current and expected future economic and market conditions and its impact on the Company’s reporting unit.** **Based on interim assessments, the Company did not identify any “triggering” events which would indicate an impairment of goodwill as of September 30, 2025.

The following table presents the composition of the Company’s intangible assets and goodwill (in thousands):

As of September 30, 2025, expected amortization expense for unamortized finite-lived intangible assets for the next five years and thereafter is as follows (in thousands):

Actual amortization expense to be reported in future periods could differ from these estimates as a result of asset impairments, acquisitions, or other facts and circumstances.

Note 8. Revenue from Contracts with Customers

The Company’s net sales are generated primarily from sales ofiDose TR, itsiStent family of products,Photrexa and associated drug formulations, and royalty income. The Company’s customers are primarily comprised of ambulatory surgery centers, hospitals and physician private practices, with third party distributors being used in certain international locations where the Company currently does not have a direct commercial presence.

The Company concluded that one performance obligation exists for the majority of its contracts with customers, which is to deliver products in accordance with the Company’s normal delivery times. Revenue is recognized when this performance obligation is satisfied, which is the point in time when the Company considers control of a product to have transferred to the customer. Revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for those products or services.

Revenue is recognized at an amount that reflects the consideration the Company expects to be entitled to in exchange for goods or services, and substantially all of the Company’s net sales for the three and nine months ended September 30, 2025 and September 30, 2024 are considered revenue from contracts with customers.

Disaggregation of Revenue

The Company’s revenues disaggregated by product category and geography for the three and nine months ended September 30, 2025 and September 30, 2024 were as follows (in thousands):

Contract Balances

Contract Assets

Amounts are recorded as accounts receivable when the Company’s right to consideration becomes unconditional. Payment terms on invoiced amounts are typically between 30 –60 days for glaucoma and corneal health products, though extended payment terms have been offered as part of theiDose TR commercial launch. However, the Company does not consider any significant financing components in customer contracts given the expected time between transfer of the promised products and the payment of the associated consideration is less thanone year. As of September 30, 2025 and December 31, 2024, substantially all amounts included in accounts receivable, net on the condensed consolidated balance sheets are related to contracts with customers.

Aside from the aforementioned contract assets, the Company does not have any contract assets given that the Company does not have any unbilled receivables and sales commissions on products are expensed within selling, general and administrative expenses within the condensed consolidated statements of operations when incurred as any incremental cost of obtaining contracts with customers would have an amortization period of less thanone year.

Contract Liabilities

Contract liabilities reflect consideration received from customers’ purchases allocated to the Company’s future performance obligations.

The Company has a performance obligation to issue a volume-based rebate to customers who may be eligible for such rebate at the conclusion of their contract term. This performance obligation is transferred over time and the Company’s method of measuring progress is the output method, whereby the progress is measured by the estimated rebate earned to date over the total rebate estimated to be earned over the contract period.

Additionally, the Company has performance obligations related to certain customers’ right to a future discount on single dose pharmaceutical purchases in the U.S., as well as voluntary patient assistance programs to provide financial assistance to qualified patients. Each of these performance obligations is expected to be recognized when the customer or patient elects to utilize the discount, which is generally within one year. The impact of these programs on revenue were not material for the periods presented.

Certain sales of the Company’s pharmaceutical products are subject to rebates under the Medicaid Drug Rebate Program (MDRP). The rebate accrual calculation requires management to estimate the volume of net sales that will be subject to these rebates. There can be significant time-lag in receiving rebate notices from each state (generally, several months or longer after a sale is recognized). Estimated MDRP rebates are recorded as a reduction of revenue in the period the related sale is recognized.

The Company’s total accrued volume-based rebates and MDRP allowances are included in accrued liabilities on the condensed consolidated balance sheets and estimated rebates accrued were $12.8 million and $8.0 million as of September 30, 2025 and December 31, 2024, respectively, as detailed below:

During the three and nine months ended September 30, 2025 and September 30, 2024, the Company did not recognize any revenue related to material changes in transaction prices regarding its contracts with customers and did not recognize any material changes in revenue related to amounts included in contract liabilities at the beginning of the period.

The Company’s net sales within a fiscal year may be impacted seasonally, as demand for U.S. ophthalmic procedures is typically softer in the first quarter and stronger in the fourth quarter of a given year.

Note 9. Net Loss per Share

Basic net loss per share is calculated by dividing the net loss by the weighted average number of common shares that were outstanding for the period, without consideration for common stock equivalents. For periods when the Company realizes a net loss, no common stock equivalents are included in the calculation of weighted average number of dilutive common stock equivalents as the effect of applying the treasury stock method is considered anti-dilutive. Due to the Company’s net loss position, basic and diluted net loss per share for each of the three and nine months ended September 30, 2025 and September 30, 2024 are the same.

The following potentially dilutive securities were not included in the calculation of diluted net loss per share because to do so would be anti-dilutive (in common stock equivalent shares, in thousands):

Note 10. Convertible Senior Notes

In June 2024 the Company executed a Convertible Notes Exchange, whereby certain qualified institutional investors exchanged$230.0 million in aggregate principal of the Company’s 2.75% convertible notes due 2027 (Convertible Notes) held for an aggregate of 4,253,423 shares of the Company’s common stock, leaving$57.5 million aggregate principal of remaining Convertible Notes outstanding. Then, on October 4, 2024, the Company issued a notice of redemption (the Redemption Notice) for all remaining$57.5 million aggregate principal outstanding of its Convertible Notes to be redeemed on December 16, 2024 (the Redemption Date) for the principal amount together with accrued and unpaid interest.

Interest expense relating to the Convertible Notes in the condensed consolidated statements of operations for the three and nine months ended September 30, 2024 was$0.4 million and$4.6 million related to contractual interest expense, respectively and$0.1 million and$0.7 million related to amortization of debt issuance costs, respectively.

Capped Call Transactions

On December 2, 2024, the Company entered into unwind agreements with certain financial institutions (Option Counterparties) to unwind 50% of the capped call transactions (Capped Call Unwind Agreements) that the Company previously entered into with such Option Counterparties in connection with the issuance of the Convertible Notes. Under the terms of the Capped Call Unwind Agreements, there was athree-day unwinding period, referred to as the Volume-Weighted Average Price (VWAP) period, before the cash settlement was delivered. At the time of signing the Capped Call Unwind Agreements, the Company recognized a derivative asset at its fair value of$53.9 million, reflecting the initial cash settlement value based on the VWAP as of the signing date, with a corresponding entry recorded to additional paid-in capital in the condensed consolidated balance sheets.

On December 6, 2024, the Capped Call Unwind Agreements were settled and the Company received$53.2 million in cash, at which point the derivative asset was derecognized. The remaining outstanding 50% of the capped call transactions will not be remeasured to fair value as long as the accounting criteria continue to be met.

Note 11. Stock-Based Compensation

The following table summarizes the allocation of stock-based compensation related to stock options and RSUs in the accompanying condensed consolidated statements of operations (in thousands):

At September 30, 2025, the total unamortized stock-based compensation expense was approximately $92.3 million, of which $10.8 million and $81.6 million was attributable to stock options and RSUs, respectively. The Company currently issues its annual stock options and RSU grants to eligible employees during the second quarter of each year.

Of the $10.8 million related to stock options, $10.3 million is attributable to time-based stock options and will be recognized over the time-based stock options’ remaining vesting terms of approximately 4.0 years (2.3 years on a weighted average basis). The remaining $0.5 million is attributable to performance-based options and will be recognized over the performance-based stock options’ remaining vesting terms of less thanone year (0.5 years on a weighted average basis).

Of the $81.6 million related to RSUs, $80.3 million is attributable to time-based RSUs and will be recognized over the RSUs’ vesting terms of approximately 4.0 years (2.8 years on a weighted-average basis). The remaining $1.3 million is attributable to performance-based RSUs and will be recognized over the performance-based RSUs’ remaining vesting terms of less thantwo years (0.7 years on a weighted average basis).

The total stock-based compensation cost capitalized in inventory was not significant for the three and nine months ended September 30, 2025 and September 30, 2024.

Note 12. Income Taxes

For the three and nine months ended September 30, 2025, the Company recorded a provision for income taxes of $0.2 million and $0.8 million, respectively, with an effective tax rate of (1.46)% and (1.52)%, respectively. For the three and nine months ended September 30, 2024, the Company recorded a provision for income taxes of $0.2 million and $0.9 million, respectively. For each of the three and nine months ended September 30, 2025 and September 30, 2024, the provision for income taxes was primarily comprised of state and foreign income tax expense, net of release of uncertain tax positions for which the statute of limitations has expired.

On July 4, 2025, House Resolution 1, commonly referred to as the One Big Beautiful Bill Act (OBBBA) was enacted into law. Key provisions of the OBBBA include the extension and modification of certain provisions of the Tax Cuts and Jobs Act of 2017, changes to bonus depreciation, adjustments to business interest expense limitations, and modifications to the treatment of research and development expenditures. The OBBBA has multiple effective dates, with certain provisions effective in 2025 and others becoming effective in 2026. In accordance with ASC 740, the effect of changes in tax rates and laws on deferred tax balances are recognized in the period when the legislation is enacted. The Company has reflected the effect on the OBBBA within the provision for income taxes and the deferred tax balances as of September 30, 2025. The OBBBA did not materially impact the Company's effective tax rate.

Note 13. Commitments and Contingencies
