Description of Business

1. DESCRIPTION OF BUSINESS

IonQ, Inc. (“IonQ” or the “Company”), formerly known as dMY Technology Group, Inc. III (“dMY”), was incorporated in the state of Delaware in September 2020 and formed as a special purpose acquisition company for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination with one or more businesses. IonQ Quantum, Inc. (formerly known as IonQ, Inc., and referred to as “Legacy IonQ” herein), was incorporated in the state of Delaware in September 2015 and is headquartered in College Park, Maryland.

On March 7, 2021, Legacy IonQ entered into an Agreement and Plan of Merger (the “Merger Agreement”) with dMY and Ion Trap Acquisition Inc. (“Merger Sub”), a direct, wholly owned subsidiary of dMY. Pursuant to the Merger Agreement, on September 30, 2021 (“the Closing Date”), the Merger Sub was merged with and into Legacy IonQ with Legacy IonQ continuing as the surviving corporation following the merger, becoming a wholly owned subsidiary of dMY and the separate corporate existence of the Merger Sub ceased (the “Business Combination”). Contemporaneously with the Business Combination, dMY changed its name to IonQ, Inc. and Legacy IonQ changed its name to IonQ Quantum, Inc.

IonQ develops quantum computers and networks designed to solve some of the world’s most complex problems, and transform business, society, and the planet for the better. To operate the quantum computers and networks, the Company has developed custom hardware, custom firmware, and an operating system to orchestrate the quantum computers.

Summary of Significant Accounting Policies

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Significant Accounting Policies

The Company’s significant accounting policies, which are disclosed in the audited financial statements for the year ended December 31, 2024, and the notes thereto are included in the Company’s Annual Report on Form 10-K (the “Annual Report”) that was filed with the Securities and Exchange Commission (“SEC”) on February 26, 2025. Since the date of that filing, there have been no material changes to the Company’s significant accounting policies except as noted below.

Basis of Preparation

The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") as determined by the Financial Accounting Standards Board (“FASB”). Such condensed consolidated financial statements include the accounts of IonQ and majority-owned and wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. For consolidated non-wholly-owned subsidiaries, a noncontrolling interest is recognized to reflect the portion of income and equity that is not attributable to the Company.

Unaudited Interim Financial Information

The interim condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared by the Company and are unaudited, pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures contained in this Quarterly Report on Form 10-Q comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), for a quarterly report and are adequate to make the information presented not misleading. The interim condensed consolidated financial statements included herein reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods presented. These interim condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto for the year ended December 31, 2024, included in the Annual Report. The condensed consolidated statements of operations and the condensed consolidated statements of comprehensive loss for the three or six months ended June 30, 2025, are not necessarily indicative of the results to be anticipated for the entire year ending December 31, 2025, or thereafter. All references to June 30, 2025 and 2024, in the notes to the condensed consolidated financial statements are unaudited.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP and the rules and regulations of the SEC require management to make estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes.

Significant estimates and assumptions are inherent in the analysis and measurement of items including, but not limited to: standalone selling price for revenue arrangements with multiple performance obligations, total expected costs for revenue arrangements recognized over time, capitalization of quantum computing system costs, useful lives for quantum computing systems, estimates of the fair value of intangible assets acquired in business combinations, and stock-based compensation for awards with performance and market conditions. Management bases its estimates and assumptions on historical experience, expectations, forecasts, and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ and be affected by changes in those estimates.

Foreign Currency

The reporting currency of the Company is the U.S. dollar. Financial statements of subsidiaries whose functional currency is not the U.S. dollar are translated at exchange rates in effect at the balance sheet date for assets and liabilities and at average exchange rates for revenues and expenses for the respective periods. Translation adjustments are recorded in accumulated other comprehensive income (loss) in the condensed consolidated balance sheets.

The Company is exposed to foreign currency risk to the extent that it enters into transactions denominated in currencies other than its subsidiaries’ respective functional currencies. Transactions denominated in currencies other than subsidiaries’ functional currencies are recorded based on exchange rates at the time such transactions arise. Changes in exchange rates with respect to amounts recorded in the Company’s condensed consolidated balance sheets related to these items will result in unrealized foreign currency transaction gains and losses based upon period-end exchange rates. The Company also records realized foreign currency transaction gains and losses upon settlement of the transactions. Foreign currency transaction gains and losses resulting from the conversion of the transaction currency to functional currency are included in other income (expense), net in the condensed consolidated statements of operations.

Fair Value Measurements

The Company evaluates the fair value of certain assets and liabilities using the fair value hierarchy. 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 at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

•
Level 1—Observable inputs, which include quoted prices in active markets;
•
Level 2—Observable inputs other than the quoted prices in active markets that are observable either directly or indirectly, such as quoted prices in markets that are not active, or other inputs such as broker quotes, benchmark yield curves, credit spreads and market interest rates for similar securities that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities;
•
Level 3—Unobservable inputs that are supported by little or no market activity and that are based on management’s assumptions, including fair value measurements determined using pricing models, discounted cash flow methodologies or similar techniques.

The Company’s assessment of the significance of a particular input to the fair value measurements requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.

For assets that are measured using quoted prices in active markets, the total fair value is the published market price per unit multiplied by the number of units held, without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs are primarily valued by reference to quoted prices of similar assets or liabilities in active markets, adjusted for any terms specific to that asset or liability. Assets that are measured using unobservable inputs, including investments in convertible debt securities of privately-held companies, use the market or income approach and may involve pricing models whose inputs require significant judgment or estimation. The inputs in these valuations may include, but are not limited to, capitalization and discount rates and earnings before interest, taxes, depreciation, and amortization (“EBITDA”) multiples.

Assets and liabilities that are measured at fair value on a non-recurring basis include property and equipment, intangible assets, and goodwill. The Company recognizes these items at fair value upon initial recognition when acquired through a business combination or an asset

acquisition or when they are considered to be impaired. The fair value of these assets and liabilities are determined with valuation techniques using the best information available and may include quoted market prices, market comparables and discounted cash flow models.

Due to their short-term nature, the carrying amounts reported in the Company’s condensed consolidated financial statements approximate the fair value for cash and cash equivalents, accounts receivable, accounts payable and accrued expenses.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include cash and checking deposits, money market funds, and U.S. government and agency securities. The Company considers all short-term highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. Restricted cash for collateralizing letters of credit and certain other obligations is included in prepaid expenses and other current assets and other noncurrent assets in the condensed consolidated balance sheets. The Company issues letters of credit in the ordinary course of business, including for lease arrangements. Letters of credit totaling $2.3 million and $2.1 million were outstanding as of June 30, 2025 and December 31, 2024, respectively.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable are non-interest bearing and represent amounts billed and currently due from customers at the gross invoiced amount as well as unbilled amounts related to unconditional rights for consideration to be received for services performed but not yet invoiced. A receivable is recorded when the Company has an unconditional right to receive payment. Accounts receivable consists of the following (in thousands):

On a periodic basis, management evaluates its accounts receivable and determines whether to provide an allowance for credit losses. This assessment is based on management’s evaluation of relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the receivable.

Allowances for credit losses were not material as of either June 30, 2025 or December 31, 2024.

Inventories, Net

Inventories are stated at the lower of cost or net realizable value, with cost computed using the weighted-average cost basis, and is recorded in prepaid expenses and other current assets in the condensed consolidated balance sheet. Inventories are evaluated regularly for excess quantities and obsolescence. This evaluation includes analysis of the Company's current and future strategic plans, risk of technological obsolescence, and general market conditions. During the three and six months ended June 30, 2025, excess and obsolescence charges were not material.

Materials and Supplies, Net

Materials and supplies, including spare parts, are carried at average cost and recorded in prepaid expenses and other current assets in the condensed consolidated balance sheets. Materials and supplies used in the production of quantum computing systems are capitalized to property and equipment when installed. Materials and supplies used to support customer contracts, for maintenance, or for research and development efforts are expensed when consumed. The Company capitalized $2.1 million and $2.6 million of materials and supplies to property and

equipment for the three months ended June 30, 2025 and 2024, respectively, and $4.2 million and $3.6 million of materials and supplies to property and equipment for the six months ended June 30, 2025 and 2024, respectively.

Materials and supplies are evaluated regularly for excess quantities and obsolescence. This evaluation includes analysis of the Company's current and future strategic plans, risk of technological obsolescence, and general market conditions. During each of the three and six months ended June 30, 2025, excess and obsolescence charges were $0.5 million, and during each of the three and six months ended June 30, 2024, excess and obsolescence charges were $0.1 million.

Investments

Management determines the appropriate classification of investments at the time of purchase based upon management’s intent with regard to such investments. The Company primarily invests in debt securities and classifies its investments as available-for-sale at the time of purchase if they are available to support either current or future operations. This classification is re-evaluated at each balance sheet date. Convertible debt securities in privately-held companies are classified as available-for-sale. Investments not considered cash equivalents, with remaining contractual maturities of one year or less from the balance sheet date are classified as short-term investments, and those with remaining contractual maturities greater than one year from the balance sheet date are classified as long-term investments. All investments are recorded at their estimated fair value, and any unrealized gains and losses are recorded in the condensed consolidated balance sheets in accumulated other comprehensive loss. Realized gains and losses on sales and maturities of investments are determined based on the specific identification method and are recognized in the condensed consolidated statements of operations in other income (expense), net. Accrued interest receivable on available-for-sale investments is recorded in the condensed consolidated balance sheets in prepaid expenses and other current assets.

The Company performs periodic evaluations to determine whether any declines in the fair value of investments below amortized cost are credit losses or impairments. The evaluation consists of qualitative and quantitative factors regarding the severity of the unrealized loss, as well as the Company’s ability and intent to hold the investments until a forecasted recovery occurs. Declines in fair value are considered to be credit losses if they are related to deterioration in credit risk or are considered impairments if it is likely that the underlying securities will be sold prior to a full recovery of their cost basis. Credit losses and impairments are determined based on the specific identification method and are reported in other income (expense), net in the condensed consolidated statements of operations.

Property and Equipment, Net

Property and equipment, net is stated at cost less accumulated depreciation. Historical cost of fixed assets is the cost as of the date acquired. Hardware and labor costs associated with the building of quantum computing systems and supporting equipment are capitalized in the period the costs are incurred when it is probable that such costs will provide future economic benefit. The costs of quantum computing systems and supporting equipment that are used in research and development activities and have alternative future uses are capitalized. Costs to maintain quantum computing systems are expensed as incurred.

Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. Useful lives are as follows:

 

Computer equipment and acquired computer software

 

3 – 5 years

Machinery, equipment, furniture and fixtures

 

4 – 7 years

Quantum computing systems

 

3 years

Leasehold improvements

 

Shorter of the lease term or the estimated useful life of the related asset

 

The Company evaluates the useful life of its assets periodically and whenever events or changes in circumstances indicate that the useful life may have changed. In assessing useful lives, the Company considers, among other factors, the use of the asset, changes in technology, and the competitive environment.

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and current operating lease liabilities and operating lease liabilities, net of current portion on the Company’s condensed consolidated balance sheets. As of June 30, 2025, the Company has no financing lease arrangements. The Company recognizes lease expense for its operating leases on a straight-line basis over the term of the lease.

The Company records a ROU asset and lease liability in connection with its operating leases. The Company’s lease portfolio is comprised primarily of real estate leases, which are accounted for as operating leases. The Company elected the practical expedient to not separate lease and non-lease components for all leases.

ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of the future minimum lease payments, including the impact of any lease incentives, as applicable, over the lease term. An amendment to a lease is assessed to determine if it represents a lease modification or a separate contract. Lease modifications are reassessed as of the effective date of the modification using an incremental borrowing rate based on the information available at the commencement date. For modified leases the Company also reassesses the lease classification as of the effective date of the modification.

The interest rate used to determine the present value of the future lease payments is the Company’s incremental borrowing rate, because the interest rate implicit in the Company’s leases is not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located.

The Company’s lease terms include periods under options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company considers contractual-based factors such as the nature and terms of the renewal or termination, asset-based factors such as physical location of the asset and entity-based factors such as the importance of the leased asset to the Company’s operations to determine the lease term. The Company generally uses the base non-cancelable lease term when determining the ROU assets and lease liabilities.

Software Development Costs

The Company incurs software development costs for internal-use software, which the Company primarily uses to provide services to its customers, as well as for external-use software that will be part of a product to be sold, leased, or marketed.

Internal-Use Software

The costs to purchase and develop internal-use software are capitalized from the time that the preliminary project stage is completed, and it is considered probable that the software will be used to perform the function intended, until the time the software is placed in service for its intended use. Any costs incurred during subsequent efforts to upgrade and enhance the functionality of the software are also capitalized. Once this software is ready for its intended use, these costs are amortized on a straight-line basis over the estimated useful life of the software, which is typically assessed to be three years. Capitalized internal-use software is recorded within intangible assets, net, in the condensed consolidated balance sheets. During the three months ended June 30, 2025 and 2024, the Company capitalized $1.9 million and $1.2 million in internal-use software costs, respectively, and during the six months ended June 30, 2025 and 2024, the Company capitalized $3.4 million and $3.8 million, respectively. The Company amortized $1.6 million and $1.3 million of capitalized internal-use software costs during the three months ended June 30, 2025 and 2024, respectively, and $3.1 million and $2.4 million of capitalized internal-use software costs during the six months ended June 30, 2025 and 2024, respectively.

External-Use Software

Costs incurred in researching and developing external-use software are expensed as incurred until technological feasibility is established. Once technological feasibility is established, software costs are capitalized until the product is available for general release to customers. Judgment is required in determining when technological feasibility of a product is established. Generally, this occurs shortly before the products are released to production. No external-use software costs were capitalized during any of the three or six months ended June 30, 2025 and 2024.

Intangible Assets, Net

The Company’s intangible assets include website domain costs, patents, intellectual property, customer relationships, developed technology, non-compete agreements, backlog, and trademarks. With respect to patents, acquisition costs include external legal and patent application costs. Intangible assets with identifiable useful lives are initially valued at acquisition cost and are amortized over their estimated useful lives using the straight-line method. Intangible assets with indefinite useful lives are assessed for impairment at least annually.

Goodwill

Goodwill is the excess of the purchase price over the fair values assigned to the net assets acquired in a business combination. The Company tests goodwill for impairment on an annual basis, which it has determined to be the first day of the fourth quarter, and whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company tests goodwill qualitatively, or

quantitatively, by comparing the fair value of the reporting unit with the unit’s carrying amount. No impairment loss was recognized for any of the three or six months ended June 30, 2025 and 2024.

Business Combinations

The Company recognizes and measures the assets acquired and liabilities assumed in a business combination based on their estimated fair values at the acquisition date. Goodwill as of the acquisition date represents the excess of the purchase consideration of an acquired business over the fair value of the underlying net tangible and intangible assets acquired net of liabilities assumed. The purchase consideration is determined based on the fair value of the assets transferred and liabilities assumed after considering any transactions that are separate from the business combination. Any adjustments to provisional amounts that are identified during the measurement period, not to exceed one year from the date of acquisition, are recorded in the reporting period in which the adjustment amounts are determined. Upon the conclusion of the measurement period, any subsequent adjustments are recorded in the Company’s condensed consolidated statements of operations.

Impairment of Long-Lived Assets

Long-lived assets, such as property and equipment and other long-term assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent the carrying amount of the underlying asset exceeds its fair value. Impairment losses were not material for any of the three or six months ended June 30, 2025 and 2024.

Warrant Liabilities

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging.” For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued upon exercise or at each reporting date for the unexercised warrants, with changes in the fair value reported in the condensed consolidated statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. The warrants of dMY assumed in the Business Combination are classified as liabilities and remeasured at each reporting period. Derivative warrant liabilities are classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.

Revenue Recognition

The Company derives revenue from the design, development, construction and sale of specialized quantum computing hardware together with related maintenance and support, from the sale of quantum networking products together with related services and maintenance, from providing access to its quantum-computing-as-a-service (“QCaaS” or “Platform” services), and from consulting services related to co-developing algorithms on the quantum computing systems. The Company applies the provisions of the FASB Accounting Standards Update (“ASU”), Revenue from Contracts with Customers (“ASC 606”), and all related applicable guidance. The core principle of ASC 606 is that an entity shall recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

To support this core principle, the Company applies the following five step approach:

1.
Identify the contract with the customer
2.
Identify the performance obligations
3.
Determine the transaction price
4.
Allocate the transaction price to the performance obligations
5.
Recognize revenue when (or as) the entity satisfies a performance obligation

Certain of the Company’s contracts contain multiple performance obligations, most commonly in contracts for the sale of specialized quantum computing hardware together with related maintenance and support and the sale of quantum networking products together with related services and maintenance. Certain contracts may also include access to the Company’s QCaaS. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when or as the performance obligation is satisfied. When there are multiple performance obligations in a contract, the Company allocates the transaction price to each performance obligation based on its standalone selling price when available. The Company determines standalone selling price based on the observable price of a product or service when it sells the

products or services separately in similar circumstances and to similar customers. Certain products and services have limited or no history of being sold on a standalone basis, requiring the Company to estimate the standalone selling price. The Company estimates the standalone selling price based on other contracts for similar products and services adjusted for differing terms than the contract being evaluated, as well as internal pricing guidelines and market factors. In addition, the Company takes into consideration the estimated costs to be incurred to satisfy the performance obligation plus an appropriate profit margin.

Performance obligations are satisfied over time if the customer receives the benefits as the Company performs the work, if the customer controls the asset as it is being produced (continuous transfer of control), or if the product being produced for the customer has no alternative use and the Company has a contractual right to payment for performance to date. For performance obligations related to specialized quantum computing hardware and consulting services, revenue is recognized over time based on the efforts incurred to date relative to the total expected effort, primarily based on a cost-to-cost input measure. The Company applies judgment to determine a reasonable method to measure progress and to estimate total expected effort. Factors considered in these estimates include the Company's historical performance, the availability, productivity and cost of labor, the nature and complexity of work to be performed, the effect of change orders, availability and cost of materials, and the effect of any delays in performance. For performance obligations related to quantum networking products and related services, revenue is recognized at the point in time when control passes to the customer, which is generally at the shipping point based on customary incoterms, or upon completion of the required services.

The Company has determined that its QCaaS contracts represent a combined, stand-ready performance obligation to provide access to its quantum computing systems together with related maintenance and support. The transaction price generally consists of a fixed fee for a minimum volume of usage to be made available over a defined period of access. Fixed fee arrangements may also include a variable component whereby customers pay an amount for usage over contractual minimums contained in the contracts. For performance obligations related to providing QCaaS access, fixed fees are recognized on a straight-line basis over the access period. Variable usage fees are recognized in the period they occur. The Company has determined that contracts that contain consulting services related to co-developing quantum computing algorithms and the ability to use its quantum computing systems to run such algorithms represent a combined performance obligation that is satisfied over-time.

For the three and six months ended June 30, 2025 and 2024, materially all revenue was recognized based on transfer of service over time. In arrangements with cloud service providers, the cloud service provider is considered the customer and IonQ does not have any contractual relationships with the cloud service providers’ end users. For these arrangements, revenue is recognized at the amount charged to the cloud service provider and does not reflect any mark-up to the end user.

The Company may enter into multiple contracts with a single counterparty at or near the same time. The Company will combine contracts and account for them as a single contract when one or more of the following criteria are met: (i) the contracts are negotiated as a package with a single commercial objective; (ii) consideration to be paid in one contract depends on the price or performance of the other contract; and (iii) goods or services promised are a single performance obligation. Consideration payable to a customer includes cash amounts that an entity pays, or expects to pay, to the customer. For arrangements that contain consideration payable to a customer, the Company uses judgment in determining whether such payments are a reduction of the transaction price or a payment to the customer for a distinct good or service.

The variable fees associated with the QCaaS are generally billed a month in arrears. Customers also have the ability to make advance payments. Advance payments are recorded as a contract liability until services are delivered or obligations are met and revenue is earned. Contract liabilities to be recognized in the succeeding 12-month period are classified as current and the remaining amounts are classified as non-current liabilities in the Company’s condensed consolidated balance sheets.

Assets Recognized from Costs to Obtain a Contract

Sales commissions paid to employees and third parties are considered incremental costs to obtain a contract with a customer. These costs are capitalized in the period a customer contract is executed and are amortized as an expense consistent with the transfer of the goods or services to the customer. Capitalized costs are recorded in prepaid expenses and other current assets and other noncurrent assets in the condensed consolidated balance sheets. Applying the practical expedient, the Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets is one year or less. As of June 30, 2025 and December 31, 2024, total capitalized costs were $2.3 million and $2.4 million, respectively. Amortization expense was $0.4 million and $0.5 million for the three months ended June 30, 2025 and 2024, respectively, and $0.7 million and $0.9 million for the six months ended June 30, 2025 and 2024, respectively, and is included in sales and marketing in the condensed consolidated statements of operations.

Research and Development

Research and development expenses consist of personnel-related costs, including salaries, benefits and stock-based compensation, and allocated overhead costs for the Company’s research and development function. Unlike a standard computer, design and development efforts continue throughout the useful life of the Company’s quantum computing systems to ensure proper calibration and optimal functionality.

Research and development expenses also include purchased hardware and software costs related to quantum computing systems constructed for research purposes that are not probable of providing future economic benefit and have no alternate future use, as well as costs associated with third-party research and development arrangements.

Stock-Based Compensation

The Company measures and records the expense related to stock-based awards based on the fair value of those awards as determined on the date of grant. The Company recognizes stock-based compensation expense over the requisite service period of the individual grant, generally equal to the vesting period and uses the straight-line method to recognize stock-based compensation. The Company uses the Black-Scholes-Merton (“Black-Scholes”) option-pricing model to determine the estimated fair value for stock options. The Black-Scholes option-pricing model requires the use of subjective assumptions, which determine the fair value of stock option awards, including the option’s expected term, the price volatility of the underlying common stock, risk-free interest rates, and the expected dividend yield of the common stock. The assumptions used to determine the fair value of the stock options represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. The Company records forfeitures as they occur.

Stock-based compensation cost for restricted stock units, performance-based restricted stock units, and restricted common stock is measured based on the fair value of the Company’s common stock on the grant date. The fair value of performance-based restricted stock units with a market condition is estimated on the date of grant using the Monte Carlo simulation model. The Monte Carlo simulation model requires the use of subjective assumptions, which determine the fair value of these awards, including price volatility, contractual term, discount rate, risk-free interest rates, and the expected dividend yield of the common stock. The assumptions used to determine the fair value of the performance-based restricted stock awards represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. For awards with a performance-based vesting condition, including those with a market condition, the Company records stock-based compensation cost if it is probable that the performance conditions will be achieved. Stock-based compensation cost will be recognized if the performance condition is satisfied, even if the market condition is not met and the award does not vest. At each reporting period, the Company reassesses the probability of the achievement of the performance conditions and any change in expense resulting from an adjustment in the estimated shares to be released is treated as a cumulative catch-up in the period of the adjustment.

The Company records stock-based compensation expense for incentive compensation liabilities based on estimated payments to employees for which the Company expects to settle the liability by granting restricted stock units. For these awards, stock-based compensation expense is accrued commencing at the service inception date, which generally precedes the grant date, through the end of the requisite service period.

Income Taxes

Income taxes are accounted for using the asset and liability method. Deferred income taxes are provided for temporary differences in recognizing certain income, expense and credit items for financial reporting purposes and tax reporting purposes. Such deferred income taxes primarily relate to the difference between the tax bases of assets and liabilities and their financial reporting amounts. Deferred tax assets and liabilities are measured by applying enacted statutory tax rates applicable to the future years in which deferred tax assets or liabilities are expected to be settled or realized.

The Company records a valuation allowance when it determines, based on available positive and negative evidence, that it is not more-likely-than-not that some portion or all of its deferred tax assets will be realized.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, restricted cash, investments, and trade accounts receivable. The Company maintains the majority of its cash, cash equivalents, restricted cash and investments with several high credit quality financial institutions. The Company’s deposits routinely exceed amounts guaranteed by the Federal Deposit Insurance Corporation.

The Company’s accounts receivable are derived from customers primarily located in the U.S., including the U.S. government. The Company performs periodic evaluations of its customers’ financial condition and generally does not require its customers to provide collateral or other security to support accounts receivable and maintains an allowance for credit losses. Credit losses historically have not been material.

Significant customers are those that represent more than 10% of the Company’s total revenue. For the three and six months ended June 30, 2025, the Company had two significant customers that accounted for 65% of total revenue and three significant customers that accounted for 73% of total revenue, respectively. For the three and six months ended June 30, 2024, the Company had two significant customers that accounted for 79% and 75% of total revenue, respectively.

Earnings (Loss) Per Share

Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding for the period. Diluted earnings per share is computed by dividing net income (loss) by the weighted average number of shares of common stock during the period, plus common stock equivalents, outstanding during the period. If the Company reports a net loss, the computation of diluted loss per share excludes the effect of dilutive common stock equivalents, as their effect would be antidilutive.

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

3. BUSINESS COMBINATIONS

2025 Acquisitions

During 2025, the Company completed three acquisitions, for which each of the purchase price allocations are based on preliminary information and subject to change. Upon completion of the final purchase price allocations, the final fair values of assets acquired and liabilities assumed and resulting goodwill may differ materially from the preliminary assessment. The Company has estimated the preliminary fair values of assets acquired and liabilities assumed in each acquisition based on information currently available and will continue to adjust those estimates as additional information pertaining to events or circumstances present at the acquisition date becomes available during the measurement period.

The Company incurred approximately $15.8 million in transaction costs, which were primarily related to fees associated with financial and legal advisors, related to closed and pending acquisitions. Transactions costs were recorded in general and administrative expenses in the condensed consolidated statements of operations.

The Company has included the revenue and expenses of each acquisition in its condensed consolidated statements of operations from the date of acquisition.

ID Quantique SA

On April 30, 2025, the Company acquired a controlling stake in ID Quantique SA (“IDQ”) for approximately $118.9 million of total consideration (the “IDQ Acquisition").

A noncontrolling interest was recognized at fair value on the acquisition date, which was determined to be the noncontrolling interest's proportionate share of the acquirees' identifiable net assets. The acquisition supports the Company’s quantum networking capabilities by expanding its quantum networking expertise and technology portfolio, including quantum-safe communications and quantum detection systems.

Privately-Held Securities

During the second quarter, the Company entered into a subscription agreement (“Investment Agreement”) to purchase $20.0 million of convertible debt securities of a privately-held entity (“Investee”). As of June 30, 2025, the total amount of privately-held securities included in other noncurrent assets on the condensed consolidated balance sheet was $20.0 million. The Company did not record any adjustments or impairments for the privately-held securities held as of June 30, 2025. The fair value of convertible debt securities is based on unobservable inputs and is classified as Level 3 in the hierarchy.

In connection with the Investment Agreement, the Investee and the Company entered into a commercial contract for access to the Company’s products and services. The Company assessed the commercial contract under the guidance within ASC 606, Revenue from Contracts with Customers, as well as the commercial substance of the arrangement considering the customer’s ability and intention to pay as well as the Company’s obligation to perform under the contract. Based on its assessment, the Company concluded the commercial contract is within the scope of ASC 606 and the Company will apply the principles within ASC 606 to measure and recognize revenue. During the three and six months ended June 30, 2025, no revenue was recognized from the commercial contract.

10. COMMITMENTS AND CONTINGENCIES

Warranties and Indemnification

The Company’s commercial services are typically warranted to perform in a manner consistent with general industry standards that are reasonably applicable and materially in accordance with the Company’s documentation under normal use and circumstances.

The Company’s arrangements generally include certain provisions for indemnifying customers against liabilities if its products or services infringe third-party intellectual property rights. To date, the Company has not incurred any material costs as a result of such obligations and has not accrued any liabilities related to such obligations in the accompanying condensed consolidated financial statements.

Stockholder Lawsuit

In May 2022, a securities class action complaint captioned Leacock v. IonQ, Inc. et al., Case No. 8:22-cv-01306, was filed by a stockholder of the Company in the United States District Court for the District of Maryland (the “Leacock Litigation”) against the Company and certain of the Company’s current officers. In June 2022, a securities class action complaint captioned Fisher v. IonQ, Inc., Case No. 8:22-cv-01306-DLB (the “Fisher Litigation”) was filed by a stockholder against the Company and certain of the Company’s current officers (“IonQ Defendants”). Both the Leacock Litigation and Fisher Litigation, which have been consolidated into a single action, allege violations of Section 10(b) of the Exchange Act, and Rule 10b-5 promulgated thereunder, and Section 20(a) of the Exchange Act and seek damages. In September 2022, the Court appointed lead plaintiffs and counsel for lead plaintiffs, and ordered lead plaintiffs to file a consolidated amended complaint. The consolidated amended complaint was filed on November 22, 2022. As part of the consolidated amended complaint, certain members of the Company’s board of directors as well as other dMY-related defendants (“Additional Defendants”) have been added as defendants to the case. On February 7, 2023, the IonQ Defendants and the Additional Defendants each filed a motion to dismiss the consolidated amended complaint. On March 23, 2023, lead plaintiffs filed their omnibus opposition to the motions to dismiss. On April 26, 2023, the IonQ Defendants and the Additional Defendants each filed a reply in support of the motions to dismiss. On September 28, 2023, the District Court of Maryland issued an order dismissing plaintiffs' claims against the IonQ Defendants and the Additional Defendants with prejudice and directed the clerk to close the case. On October 26, 2023, the plaintiffs filed a motion for post-judgment relief, seeking to amend their consolidated amended complaint. The IonQ Defendants and Additional Defendants filed oppositions to plaintiffs’ motion on December 1, 2023, and plaintiffs filed their reply on January 8, 2024. On July 10, 2024, the plaintiffs' motion for post-judgment relief was denied and the District Court of Maryland directed the clerk to close the case. On July 26, 2024, the plaintiffs filed a Notice of Appeal with the Fourth Circuit Court of Appeals seeking to review the trial court's decision. Plaintiffs filed their Opening Brief in the Fourth Circuit on September 9, 2024. A response brief by IonQ Defendants was filed on October 8, 2024 and plaintiffs’ reply brief was filed on October 29, 2024. Oral argument in the Fourth Circuit occurred on January 31, 2025. On April 8, 2025, the Fourth Circuit held for the IonQ Defendants in a published opinion. As of July 7, 2025, the deadline for plaintiffs to file an appeal with the United States Supreme Court lapsed, and there are no other avenues for plaintiffs to appeal, which means that the Fourth Circuit’s decision upholding the trial court's dismissal with prejudice stands. This case is now considered closed.

Warrants

11. WARRANTS

In November 2019, contemporaneously with a revenue arrangement, the Company entered into a contract, pursuant to which the Company agreed to issue warrants to acquire shares of Legacy IonQ Series B-1 preferred stock (the “Warrant Shares”) to a customer, subject to certain vesting events. Upon closing of the Business Combination, these warrants exercisable for Legacy IonQ Series B-1 preferred stock were assumed by the Company and converted into a warrant to purchase shares of common stock. In August 2020, 543,152 of the Warrant Shares vested and became immediately exercisable. The exercise price for the vested Warrant Shares is $1.38 per share and the warrant is exercisable through November 2029. Effective November 2024, no additional Warrant Shares can vest pursuant to the terms of the warrant agreement.

As part of the Business Combination, the Company assumed 7,500,000 public warrants on September 30, 2021. As of June 30, 2025, there were 1,834,462 public warrants to purchase common stock outstanding. Each warrant entitles the registered holder to purchase one share of common stock at a price of $11.50 per share. The public warrants are classified as liabilities and remeasured at each reporting period. No public warrants have been redeemed by the Company as of June 30, 2025.

12. AT-THE-MARKET OFFERING

In February 2025, in connection with the commencement of an "at the market" offering program, the Company entered into an Equity Distribution Agreement (the "Equity Distribution Agreement") with Morgan Stanley & Co. LLC and Needham & Company, LLC, as sales agents ("the Sales Agents"), pursuant to which the Company could offer and sell, from time to time, through or to the Sales Agents, shares of the Company's common stock, par value $0.0001 per share (the "Shares"), having an aggregate gross offering price of up to $500 million ("2025 ATM Offering Program"). The Sales Agents were entitled to a commission of up to 3.25% of the gross proceeds of all shares sold under the Equity Distribution Agreement. On March 10, 2025, the Company terminated the Equity Distribution Agreement, after which no further Shares could be sold through the 2025 ATM Offering Program.

During the six months ended June 30, 2025, the Company sold a total of 16,038,460 shares of common stock through the 2025 ATM Offering Program for an aggregate purchase prices of $358.3 million, net of issuance costs of $14.3 million.

14. STOCK-BASED COMPENSATION

Equity Incentive Plans

The Company has a 2015 Equity Incentive Plan (the “2015 Plan”), which provided for the grant of share-based compensation to certain officers, directors, employees, consultants, and advisors. Upon the closing of the Business Combination, no further awards were made pursuant to the 2015 Plan and all outstanding Legacy IonQ stock options under the 2015 Plan were assumed by the Company. Such stock options granted under the 2015 Plan will continue to be governed by the terms of the 2015 Plan and the stock option agreements thereunder, until such outstanding options are exercised or until they terminate or expire. For awards granted under the 2015 Plan, vesting generally occurs over four to five years from the date of grant.

In August 2021, the Company’s board of directors adopted the 2021 Equity Incentive Plan (the “2021 Plan”), which was subsequently approved by the Company’s stockholders in September 2021, and became effective upon the closing of the Business Combination. The 2021 Plan provides for the grant of stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards (“RSU”), performance awards and other forms of awards to employees, directors, and consultants. The number of shares of the Company’s common stock reserved for issuance under the 2021 Plan automatically increases on January 1 of each year, through and including January 1, 2031, by 5% of the Fully Diluted Common Stock (as defined in the 2021 Plan) outstanding on December 31 of the preceding year, or a lesser number of shares determined by the Company’s board of directors prior to such increase. As of January 1, 2025, the number of shares reserved for issuance under the 2021

Plan increased by 14,532,010. For awards granted under the 2021 Plan, vesting terms range from less than one year to four years from the date of grant. As of June 30, 2025, the Company had 31,633,456 shares available for grant under the 2021 Plan.

In May 2025, in connection with the Lightsynq Acquisition, the Company assumed the Lightsynq Technologies Inc. 2024 Equity Incentive Plan (the “Lightsynq Plan”). Upon closing of the Lightsynq Acquisition, no further awards were made pursuant to the Lightsynq Plan and certain outstanding Lightsynq stock options under the Lightsynq Plan were assumed by the Company. Such stock options granted under the Lightsynq Plan will continue to be governed by the terms of the Lightsynq Plan and the stock option agreements thereunder, until such outstanding options are exercised or until they terminate or expire. For awards granted under the Lightsynq Plan, vesting generally occurs over four years from the date of grant. As of June 30, 2025, the Company had no shares available for grant under the Lightsynq Plan.

Under each equity incentive plan, all options granted have a contractual term of 10 years.

Stock Options

The Company estimates the fair value of stock options on the date of grant using the Black-Scholes option pricing model. The Black-Scholes option-pricing model requires estimates of highly subjective assumptions, which affect the fair value of each stock option. The assumptions used to estimate the fair value of stock options are as follows:

Performance-Based Restricted Stock Units

The Company grants performance-based restricted stock unit awards (“PSU”) to certain officers, employees, and consultants, which vest over approximately two to four years. The number of shares that can be earned will range from 0% to 300% of the target number of shares, based on the Company's achievement of certain financial and technical goals, as well as a stock price hurdle requirement for a portion of the awards. In the event that the stock price hurdle is not met at the time the PSUs vest, the maximum PSU opportunity shall be limited to target (100%) performance.

In February 2025, the Company granted a PSU award to its President and Chief Executive Officer, which vests over three years. The number of shares that can be earned will range from 0% to 200% of the target number of shares based on the Company's achievement of certain performance goals.

The number of PSUs expected to vest and for which compensation cost has been recognized is based on the number of awards that the Company believes are probable of vesting as of June 30, 2025.

For the portion of the PSUs subject to the stock price hurdle, the fair value was determined using a Monte Carlo simulation model. The Monte Carlo simulation model requires estimates of subjective assumptions, which affect the fair value of each PSU. The assumptions used to estimate the fair value of PSUs subject to the stock price hurdle are as follows:

Income Taxes

15. INCOME TAXES

An income tax benefit of $15.3 million was recognized for the three and six months ended June 30, 2025, resulting from a partial release of U.S. federal and state valuation allowances, which was recorded as a discrete item in the second quarter due to the deferred tax liabilities related to identifiable intangibles from the Lightsynq Acquisition. Income tax expense, due to the Company's international operations, was less than $0.1

million for the three and six months ended June 30, 2024. The effective tax rate for each period differs from the statutory rate primarily as a result of not recognizing a deferred tax asset for losses due to having a valuation allowance against deferred tax assets.

The realization of tax benefits of deferred tax assets is dependent upon future levels of taxable income, of an appropriate character, in the periods the items are expected to be deductible or taxable. Based on the available objective evidence, the Company does not believe it is more likely than not that the net deferred tax assets will be realizable. Accordingly, the Company has provided a valuation allowance against the net deferred tax assets as of June 30, 2025, and December 31, 2024. The Company intends to maintain the remaining valuation allowance until sufficient positive evidence exists to support a reversal of, or decrease in, the valuation allowance.

On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was signed into law. This legislation contains a broad range of tax reform provisions affecting businesses. The Company is assessing the legislation and its effect on the consolidated financial statements.

18. SUBSEQUENT EVENTS

In July 2025, the Company entered into an underwriting agreement with J.P. Morgan Securities LLC, providing for the offer and sale of 14,165,708 shares of the Company's common stock, par value $0.0001 per share, at a price of $55.49 per share, 3,855,557 pre-funded warrants to purchase an aggregate of 3,855,557 shares of common stock at a price to the public of $55.49 less the pre-funded warrant exercise price, and 36,042,530 Series A warrants to purchase 36,042,530 shares of the Company's common stock at no additional consideration. The offering closed on July 9, 2025, for aggregate proceeds of $980.0 million, net of certain issuance costs.

On July 11, 2025, the Company completed the acquisition of Capella Space Corporation, an American space technology company with synthetic aperture radar and satellite solutions for government and commercial applications, for 7,401,396 shares of common stock, subject to customary post-closing adjustments. Due to the limited time between the acquisition date and the Company's filing of this Quarterly Report on Form 10-Q, the initial accounting for the business combination is incomplete and the Company is not yet able to disclose the preliminary amounts to be recognized as of the acquisition date for assets acquired and liabilities assumed.

Summary of Significant Accounting Policies (Policies)

Significant Accounting Policies

Significant Accounting Policies

The Company’s significant accounting policies, which are disclosed in the audited financial statements for the year ended December 31, 2024, and the notes thereto are included in the Company’s Annual Report on Form 10-K (the “Annual Report”) that was filed with the Securities and Exchange Commission (“SEC”) on February 26, 2025. Since the date of that filing, there have been no material changes to the Company’s significant accounting policies except as noted below.

Basis of Preparation

Basis of Preparation

The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") as determined by the Financial Accounting Standards Board (“FASB”). Such condensed consolidated financial statements include the accounts of IonQ and majority-owned and wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. For consolidated non-wholly-owned subsidiaries, a noncontrolling interest is recognized to reflect the portion of income and equity that is not attributable to the Company.
Unaudited Interim Financial Information

Unaudited Interim Financial Information

The interim condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared by the Company and are unaudited, pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures contained in this Quarterly Report on Form 10-Q comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), for a quarterly report and are adequate to make the information presented not misleading. The interim condensed consolidated financial statements included herein reflect all adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods presented. These interim condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto for the year ended December 31, 2024, included in the Annual Report. The condensed consolidated statements of operations and the condensed consolidated statements of comprehensive loss for the three or six months ended June 30, 2025, are not necessarily indicative of the results to be anticipated for the entire year ending December 31, 2025, or thereafter. All references to June 30, 2025 and 2024, in the notes to the condensed consolidated financial statements are unaudited.

Use of Estimates

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP and the rules and regulations of the SEC require management to make estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes.

Significant estimates and assumptions are inherent in the analysis and measurement of items including, but not limited to: standalone selling price for revenue arrangements with multiple performance obligations, total expected costs for revenue arrangements recognized over time, capitalization of quantum computing system costs, useful lives for quantum computing systems, estimates of the fair value of intangible assets acquired in business combinations, and stock-based compensation for awards with performance and market conditions. Management bases its estimates and assumptions on historical experience, expectations, forecasts, and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ and be affected by changes in those estimates.

Foreign Currency

Foreign Currency

The reporting currency of the Company is the U.S. dollar. Financial statements of subsidiaries whose functional currency is not the U.S. dollar are translated at exchange rates in effect at the balance sheet date for assets and liabilities and at average exchange rates for revenues and expenses for the respective periods. Translation adjustments are recorded in accumulated other comprehensive income (loss) in the condensed consolidated balance sheets.

The Company is exposed to foreign currency risk to the extent that it enters into transactions denominated in currencies other than its subsidiaries’ respective functional currencies. Transactions denominated in currencies other than subsidiaries’ functional currencies are recorded based on exchange rates at the time such transactions arise. Changes in exchange rates with respect to amounts recorded in the Company’s condensed consolidated balance sheets related to these items will result in unrealized foreign currency transaction gains and losses based upon period-end exchange rates. The Company also records realized foreign currency transaction gains and losses upon settlement of the transactions. Foreign currency transaction gains and losses resulting from the conversion of the transaction currency to functional currency are included in other income (expense), net in the condensed consolidated statements of operations.
Fair Value Measurements

Fair Value Measurements

The Company evaluates the fair value of certain assets and liabilities using the fair value hierarchy. 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 at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

•
Level 1—Observable inputs, which include quoted prices in active markets;
•
Level 2—Observable inputs other than the quoted prices in active markets that are observable either directly or indirectly, such as quoted prices in markets that are not active, or other inputs such as broker quotes, benchmark yield curves, credit spreads and market interest rates for similar securities that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities;
•
Level 3—Unobservable inputs that are supported by little or no market activity and that are based on management’s assumptions, including fair value measurements determined using pricing models, discounted cash flow methodologies or similar techniques.

The Company’s assessment of the significance of a particular input to the fair value measurements requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.

For assets that are measured using quoted prices in active markets, the total fair value is the published market price per unit multiplied by the number of units held, without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs are primarily valued by reference to quoted prices of similar assets or liabilities in active markets, adjusted for any terms specific to that asset or liability. Assets that are measured using unobservable inputs, including investments in convertible debt securities of privately-held companies, use the market or income approach and may involve pricing models whose inputs require significant judgment or estimation. The inputs in these valuations may include, but are not limited to, capitalization and discount rates and earnings before interest, taxes, depreciation, and amortization (“EBITDA”) multiples.

Assets and liabilities that are measured at fair value on a non-recurring basis include property and equipment, intangible assets, and goodwill. The Company recognizes these items at fair value upon initial recognition when acquired through a business combination or an asset

acquisition or when they are considered to be impaired. The fair value of these assets and liabilities are determined with valuation techniques using the best information available and may include quoted market prices, market comparables and discounted cash flow models.

Due to their short-term nature, the carrying amounts reported in the Company’s condensed consolidated financial statements approximate the fair value for cash and cash equivalents, accounts receivable, accounts payable and accrued expenses.

Cash, Cash Equivalents and Restricted Cash

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include cash and checking deposits, money market funds, and U.S. government and agency securities. The Company considers all short-term highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. Restricted cash for collateralizing letters of credit and certain other obligations is included in prepaid expenses and other current assets and other noncurrent assets in the condensed consolidated balance sheets. The Company issues letters of credit in the ordinary course of business, including for lease arrangements. Letters of credit totaling $2.3 million and $2.1 million were outstanding as of June 30, 2025 and December 31, 2024, respectively.

Accounts Receivable and Allowance for Credit Losses

Accounts Receivable and Allowance for Credit Losses

Accounts receivable are non-interest bearing and represent amounts billed and currently due from customers at the gross invoiced amount as well as unbilled amounts related to unconditional rights for consideration to be received for services performed but not yet invoiced. A receivable is recorded when the Company has an unconditional right to receive payment. Accounts receivable consists of the following (in thousands):

On a periodic basis, management evaluates its accounts receivable and determines whether to provide an allowance for credit losses. This assessment is based on management’s evaluation of relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the receivable.

Allowances for credit losses were not material as of either June 30, 2025 or December 31, 2024.

Inventories, Net

Inventories, Net

Inventories are stated at the lower of cost or net realizable value, with cost computed using the weighted-average cost basis, and is recorded in prepaid expenses and other current assets in the condensed consolidated balance sheet. Inventories are evaluated regularly for excess quantities and obsolescence. This evaluation includes analysis of the Company's current and future strategic plans, risk of technological obsolescence, and general market conditions. During the three and six months ended June 30, 2025, excess and obsolescence charges were not material.
Materials and Supplies, Net

Materials and Supplies, Net

Materials and supplies, including spare parts, are carried at average cost and recorded in prepaid expenses and other current assets in the condensed consolidated balance sheets. Materials and supplies used in the production of quantum computing systems are capitalized to property and equipment when installed. Materials and supplies used to support customer contracts, for maintenance, or for research and development efforts are expensed when consumed. The Company capitalized $2.1 million and $2.6 million of materials and supplies to property and

equipment for the three months ended June 30, 2025 and 2024, respectively, and $4.2 million and $3.6 million of materials and supplies to property and equipment for the six months ended June 30, 2025 and 2024, respectively.

Materials and supplies are evaluated regularly for excess quantities and obsolescence. This evaluation includes analysis of the Company's current and future strategic plans, risk of technological obsolescence, and general market conditions. During each of the three and six months ended June 30, 2025, excess and obsolescence charges were $0.5 million, and during each of the three and six months ended June 30, 2024, excess and obsolescence charges were $0.1 million.

Investments

Investments

Management determines the appropriate classification of investments at the time of purchase based upon management’s intent with regard to such investments. The Company primarily invests in debt securities and classifies its investments as available-for-sale at the time of purchase if they are available to support either current or future operations. This classification is re-evaluated at each balance sheet date. Convertible debt securities in privately-held companies are classified as available-for-sale. Investments not considered cash equivalents, with remaining contractual maturities of one year or less from the balance sheet date are classified as short-term investments, and those with remaining contractual maturities greater than one year from the balance sheet date are classified as long-term investments. All investments are recorded at their estimated fair value, and any unrealized gains and losses are recorded in the condensed consolidated balance sheets in accumulated other comprehensive loss. Realized gains and losses on sales and maturities of investments are determined based on the specific identification method and are recognized in the condensed consolidated statements of operations in other income (expense), net. Accrued interest receivable on available-for-sale investments is recorded in the condensed consolidated balance sheets in prepaid expenses and other current assets.

The Company performs periodic evaluations to determine whether any declines in the fair value of investments below amortized cost are credit losses or impairments. The evaluation consists of qualitative and quantitative factors regarding the severity of the unrealized loss, as well as the Company’s ability and intent to hold the investments until a forecasted recovery occurs. Declines in fair value are considered to be credit losses if they are related to deterioration in credit risk or are considered impairments if it is likely that the underlying securities will be sold prior to a full recovery of their cost basis. Credit losses and impairments are determined based on the specific identification method and are reported in other income (expense), net in the condensed consolidated statements of operations.

Property and Equipment, Net

Property and Equipment, Net

Property and equipment, net is stated at cost less accumulated depreciation. Historical cost of fixed assets is the cost as of the date acquired. Hardware and labor costs associated with the building of quantum computing systems and supporting equipment are capitalized in the period the costs are incurred when it is probable that such costs will provide future economic benefit. The costs of quantum computing systems and supporting equipment that are used in research and development activities and have alternative future uses are capitalized. Costs to maintain quantum computing systems are expensed as incurred.

Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. Useful lives are as follows:

 

Computer equipment and acquired computer software

 

3 – 5 years

Machinery, equipment, furniture and fixtures

 

4 – 7 years

Quantum computing systems

 

3 years

Leasehold improvements

 

Shorter of the lease term or the estimated useful life of the related asset

 

The Company evaluates the useful life of its assets periodically and whenever events or changes in circumstances indicate that the useful life may have changed. In assessing useful lives, the Company considers, among other factors, the use of the asset, changes in technology, and the competitive environment.

Leases

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and current operating lease liabilities and operating lease liabilities, net of current portion on the Company’s condensed consolidated balance sheets. As of June 30, 2025, the Company has no financing lease arrangements. The Company recognizes lease expense for its operating leases on a straight-line basis over the term of the lease.

The Company records a ROU asset and lease liability in connection with its operating leases. The Company’s lease portfolio is comprised primarily of real estate leases, which are accounted for as operating leases. The Company elected the practical expedient to not separate lease and non-lease components for all leases.

ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of the future minimum lease payments, including the impact of any lease incentives, as applicable, over the lease term. An amendment to a lease is assessed to determine if it represents a lease modification or a separate contract. Lease modifications are reassessed as of the effective date of the modification using an incremental borrowing rate based on the information available at the commencement date. For modified leases the Company also reassesses the lease classification as of the effective date of the modification.

The interest rate used to determine the present value of the future lease payments is the Company’s incremental borrowing rate, because the interest rate implicit in the Company’s leases is not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located.

The Company’s lease terms include periods under options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company considers contractual-based factors such as the nature and terms of the renewal or termination, asset-based factors such as physical location of the asset and entity-based factors such as the importance of the leased asset to the Company’s operations to determine the lease term. The Company generally uses the base non-cancelable lease term when determining the ROU assets and lease liabilities.

Software Development Costs

Software Development Costs

The Company incurs software development costs for internal-use software, which the Company primarily uses to provide services to its customers, as well as for external-use software that will be part of a product to be sold, leased, or marketed.

Internal-Use Software

The costs to purchase and develop internal-use software are capitalized from the time that the preliminary project stage is completed, and it is considered probable that the software will be used to perform the function intended, until the time the software is placed in service for its intended use. Any costs incurred during subsequent efforts to upgrade and enhance the functionality of the software are also capitalized. Once this software is ready for its intended use, these costs are amortized on a straight-line basis over the estimated useful life of the software, which is typically assessed to be three years. Capitalized internal-use software is recorded within intangible assets, net, in the condensed consolidated balance sheets. During the three months ended June 30, 2025 and 2024, the Company capitalized $1.9 million and $1.2 million in internal-use software costs, respectively, and during the six months ended June 30, 2025 and 2024, the Company capitalized $3.4 million and $3.8 million, respectively. The Company amortized $1.6 million and $1.3 million of capitalized internal-use software costs during the three months ended June 30, 2025 and 2024, respectively, and $3.1 million and $2.4 million of capitalized internal-use software costs during the six months ended June 30, 2025 and 2024, respectively.

External-Use Software

Costs incurred in researching and developing external-use software are expensed as incurred until technological feasibility is established. Once technological feasibility is established, software costs are capitalized until the product is available for general release to customers. Judgment is required in determining when technological feasibility of a product is established. Generally, this occurs shortly before the products are released to production. No external-use software costs were capitalized during any of the three or six months ended June 30, 2025 and 2024.
Intangible Assets, Net

Intangible Assets, Net

The Company’s intangible assets include website domain costs, patents, intellectual property, customer relationships, developed technology, non-compete agreements, backlog, and trademarks. With respect to patents, acquisition costs include external legal and patent application costs. Intangible assets with identifiable useful lives are initially valued at acquisition cost and are amortized over their estimated useful lives using the straight-line method. Intangible assets with indefinite useful lives are assessed for impairment at least annually.

Goodwill

Goodwill

Goodwill is the excess of the purchase price over the fair values assigned to the net assets acquired in a business combination. The Company tests goodwill for impairment on an annual basis, which it has determined to be the first day of the fourth quarter, and whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company tests goodwill qualitatively, or

quantitatively, by comparing the fair value of the reporting unit with the unit’s carrying amount. No impairment loss was recognized for any of the three or six months ended June 30, 2025 and 2024.
Business Combinations

Business Combinations

The Company recognizes and measures the assets acquired and liabilities assumed in a business combination based on their estimated fair values at the acquisition date. Goodwill as of the acquisition date represents the excess of the purchase consideration of an acquired business over the fair value of the underlying net tangible and intangible assets acquired net of liabilities assumed. The purchase consideration is determined based on the fair value of the assets transferred and liabilities assumed after considering any transactions that are separate from the business combination. Any adjustments to provisional amounts that are identified during the measurement period, not to exceed one year from the date of acquisition, are recorded in the reporting period in which the adjustment amounts are determined. Upon the conclusion of the measurement period, any subsequent adjustments are recorded in the Company’s condensed consolidated statements of operations.
Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

Long-lived assets, such as property and equipment and other long-term assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent the carrying amount of the underlying asset exceeds its fair value. Impairment losses were not material for any of the three or six months ended June 30, 2025 and 2024.

Warrant Liabilities

Warrant Liabilities

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging.” For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued upon exercise or at each reporting date for the unexercised warrants, with changes in the fair value reported in the condensed consolidated statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. The warrants of dMY assumed in the Business Combination are classified as liabilities and remeasured at each reporting period. Derivative warrant liabilities are classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.

Revenue Recognition

Revenue Recognition

The Company derives revenue from the design, development, construction and sale of specialized quantum computing hardware together with related maintenance and support, from the sale of quantum networking products together with related services and maintenance, from providing access to its quantum-computing-as-a-service (“QCaaS” or “Platform” services), and from consulting services related to co-developing algorithms on the quantum computing systems. The Company applies the provisions of the FASB Accounting Standards Update (“ASU”), Revenue from Contracts with Customers (“ASC 606”), and all related applicable guidance. The core principle of ASC 606 is that an entity shall recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

To support this core principle, the Company applies the following five step approach:

1.
Identify the contract with the customer
2.
Identify the performance obligations
3.
Determine the transaction price
4.
Allocate the transaction price to the performance obligations
5.
Recognize revenue when (or as) the entity satisfies a performance obligation

Certain of the Company’s contracts contain multiple performance obligations, most commonly in contracts for the sale of specialized quantum computing hardware together with related maintenance and support and the sale of quantum networking products together with related services and maintenance. Certain contracts may also include access to the Company’s QCaaS. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when or as the performance obligation is satisfied. When there are multiple performance obligations in a contract, the Company allocates the transaction price to each performance obligation based on its standalone selling price when available. The Company determines standalone selling price based on the observable price of a product or service when it sells the

products or services separately in similar circumstances and to similar customers. Certain products and services have limited or no history of being sold on a standalone basis, requiring the Company to estimate the standalone selling price. The Company estimates the standalone selling price based on other contracts for similar products and services adjusted for differing terms than the contract being evaluated, as well as internal pricing guidelines and market factors. In addition, the Company takes into consideration the estimated costs to be incurred to satisfy the performance obligation plus an appropriate profit margin.

Performance obligations are satisfied over time if the customer receives the benefits as the Company performs the work, if the customer controls the asset as it is being produced (continuous transfer of control), or if the product being produced for the customer has no alternative use and the Company has a contractual right to payment for performance to date. For performance obligations related to specialized quantum computing hardware and consulting services, revenue is recognized over time based on the efforts incurred to date relative to the total expected effort, primarily based on a cost-to-cost input measure. The Company applies judgment to determine a reasonable method to measure progress and to estimate total expected effort. Factors considered in these estimates include the Company's historical performance, the availability, productivity and cost of labor, the nature and complexity of work to be performed, the effect of change orders, availability and cost of materials, and the effect of any delays in performance. For performance obligations related to quantum networking products and related services, revenue is recognized at the point in time when control passes to the customer, which is generally at the shipping point based on customary incoterms, or upon completion of the required services.

The Company has determined that its QCaaS contracts represent a combined, stand-ready performance obligation to provide access to its quantum computing systems together with related maintenance and support. The transaction price generally consists of a fixed fee for a minimum volume of usage to be made available over a defined period of access. Fixed fee arrangements may also include a variable component whereby customers pay an amount for usage over contractual minimums contained in the contracts. For performance obligations related to providing QCaaS access, fixed fees are recognized on a straight-line basis over the access period. Variable usage fees are recognized in the period they occur. The Company has determined that contracts that contain consulting services related to co-developing quantum computing algorithms and the ability to use its quantum computing systems to run such algorithms represent a combined performance obligation that is satisfied over-time.

For the three and six months ended June 30, 2025 and 2024, materially all revenue was recognized based on transfer of service over time. In arrangements with cloud service providers, the cloud service provider is considered the customer and IonQ does not have any contractual relationships with the cloud service providers’ end users. For these arrangements, revenue is recognized at the amount charged to the cloud service provider and does not reflect any mark-up to the end user.

The Company may enter into multiple contracts with a single counterparty at or near the same time. The Company will combine contracts and account for them as a single contract when one or more of the following criteria are met: (i) the contracts are negotiated as a package with a single commercial objective; (ii) consideration to be paid in one contract depends on the price or performance of the other contract; and (iii) goods or services promised are a single performance obligation. Consideration payable to a customer includes cash amounts that an entity pays, or expects to pay, to the customer. For arrangements that contain consideration payable to a customer, the Company uses judgment in determining whether such payments are a reduction of the transaction price or a payment to the customer for a distinct good or service.

The variable fees associated with the QCaaS are generally billed a month in arrears. Customers also have the ability to make advance payments. Advance payments are recorded as a contract liability until services are delivered or obligations are met and revenue is earned. Contract liabilities to be recognized in the succeeding 12-month period are classified as current and the remaining amounts are classified as non-current liabilities in the Company’s condensed consolidated balance sheets.

Assets Recognized from Costs to Obtain a Contract

Sales commissions paid to employees and third parties are considered incremental costs to obtain a contract with a customer. These costs are capitalized in the period a customer contract is executed and are amortized as an expense consistent with the transfer of the goods or services to the customer. Capitalized costs are recorded in prepaid expenses and other current assets and other noncurrent assets in the condensed consolidated balance sheets. Applying the practical expedient, the Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets is one year or less. As of June 30, 2025 and December 31, 2024, total capitalized costs were $2.3 million and $2.4 million, respectively. Amortization expense was $0.4 million and $0.5 million for the three months ended June 30, 2025 and 2024, respectively, and $0.7 million and $0.9 million for the six months ended June 30, 2025 and 2024, respectively, and is included in sales and marketing in the condensed consolidated statements of operations.

Research and Development

Research and Development

Research and development expenses consist of personnel-related costs, including salaries, benefits and stock-based compensation, and allocated overhead costs for the Company’s research and development function. Unlike a standard computer, design and development efforts continue throughout the useful life of the Company’s quantum computing systems to ensure proper calibration and optimal functionality.

Research and development expenses also include purchased hardware and software costs related to quantum computing systems constructed for research purposes that are not probable of providing future economic benefit and have no alternate future use, as well as costs associated with third-party research and development arrangements.

Stock-Based Compensation

Stock-Based Compensation

The Company measures and records the expense related to stock-based awards based on the fair value of those awards as determined on the date of grant. The Company recognizes stock-based compensation expense over the requisite service period of the individual grant, generally equal to the vesting period and uses the straight-line method to recognize stock-based compensation. The Company uses the Black-Scholes-Merton (“Black-Scholes”) option-pricing model to determine the estimated fair value for stock options. The Black-Scholes option-pricing model requires the use of subjective assumptions, which determine the fair value of stock option awards, including the option’s expected term, the price volatility of the underlying common stock, risk-free interest rates, and the expected dividend yield of the common stock. The assumptions used to determine the fair value of the stock options represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. The Company records forfeitures as they occur.

Stock-based compensation cost for restricted stock units, performance-based restricted stock units, and restricted common stock is measured based on the fair value of the Company’s common stock on the grant date. The fair value of performance-based restricted stock units with a market condition is estimated on the date of grant using the Monte Carlo simulation model. The Monte Carlo simulation model requires the use of subjective assumptions, which determine the fair value of these awards, including price volatility, contractual term, discount rate, risk-free interest rates, and the expected dividend yield of the common stock. The assumptions used to determine the fair value of the performance-based restricted stock awards represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. For awards with a performance-based vesting condition, including those with a market condition, the Company records stock-based compensation cost if it is probable that the performance conditions will be achieved. Stock-based compensation cost will be recognized if the performance condition is satisfied, even if the market condition is not met and the award does not vest. At each reporting period, the Company reassesses the probability of the achievement of the performance conditions and any change in expense resulting from an adjustment in the estimated shares to be released is treated as a cumulative catch-up in the period of the adjustment.

The Company records stock-based compensation expense for incentive compensation liabilities based on estimated payments to employees for which the Company expects to settle the liability by granting restricted stock units. For these awards, stock-based compensation expense is accrued commencing at the service inception date, which generally precedes the grant date, through the end of the requisite service period.
Income Taxes

Income Taxes

Income taxes are accounted for using the asset and liability method. Deferred income taxes are provided for temporary differences in recognizing certain income, expense and credit items for financial reporting purposes and tax reporting purposes. Such deferred income taxes primarily relate to the difference between the tax bases of assets and liabilities and their financial reporting amounts. Deferred tax assets and liabilities are measured by applying enacted statutory tax rates applicable to the future years in which deferred tax assets or liabilities are expected to be settled or realized.

The Company records a valuation allowance when it determines, based on available positive and negative evidence, that it is not more-likely-than-not that some portion or all of its deferred tax assets will be realized.

Concentrations of Credit Risk

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, restricted cash, investments, and trade accounts receivable. The Company maintains the majority of its cash, cash equivalents, restricted cash and investments with several high credit quality financial institutions. The Company’s deposits routinely exceed amounts guaranteed by the Federal Deposit Insurance Corporation.

The Company’s accounts receivable are derived from customers primarily located in the U.S., including the U.S. government. The Company performs periodic evaluations of its customers’ financial condition and generally does not require its customers to provide collateral or other security to support accounts receivable and maintains an allowance for credit losses. Credit losses historically have not been material.

Significant customers are those that represent more than 10% of the Company’s total revenue. For the three and six months ended June 30, 2025, the Company had two significant customers that accounted for 65% of total revenue and three significant customers that accounted for 73% of total revenue, respectively. For the three and six months ended June 30, 2024, the Company had two significant customers that accounted for 79% and 75% of total revenue, respectively.
Earnings (Loss) Per Share

Earnings (Loss) Per Share

Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding for the period. Diluted earnings per share is computed by dividing net income (loss) by the weighted average number of shares of common stock during the period, plus common stock equivalents, outstanding during the period. If the Company reports a net loss, the computation of diluted loss per share excludes the effect of dilutive common stock equivalents, as their effect would be antidilutive.
