Description of Business

Description of Business	12 Months Ended
	Dec. 31, 2022
Description of Business	1. DESCRIPTION OF BUSINESS Rigetti Computing, Inc. and its subsidiaries (collectively, the “Company” or “Rigetti”), builds quantum computers and the superconducting quantum processors that power them. Through the Company’s Quantum Computing as a Service (“QCaaS”) platform, the Company’s machines can be integrated into any public, private or hybrid cloud. The Company offers product types of Platform, Research and Software Tools usage in application areas of benchmarking, chemical simulation, education/entertainment, machine learning, and optimization. The Company is located and headquartered in Berkeley, California. The Company also operates in Fremont, California; London, United Kingdom; Adelaide, Australia; British Columbia, Canada and Munich, Germany. The Company’s revenue is derived primarily from operations in the United States and the United Kingdom. Basis of Presentation On March 2, 2022 (the “Closing Date”), a merger transaction between Rigetti Holdings, Inc. (“Legacy Rigetti”) and Supernova Partners Acquisition Company II, Ltd. (“SNII”) was completed (the “Business Combination”, see Note 3). In connection with the closing of the Business Combination, the Company changed its name to Rigetti Computing, Inc. and all of SNII Class A ordinary shares and SNII Class B ordinary shares automatically converted into shares of Common Stock, par value $0.0001, of the Company (the “Common Stock”) on a one-for-one The Company determined that Legacy Rigetti was the accounting acquirer in the Business Combination based on an analysis of the criteria outlined in Accounting Standards Codification (ASC) 805, Business Combination. The determination was primarily based on the following facts: • Former Legacy Rigetti stockholders have a controlling voting interest in the Company; • The Company’s board of directors as of immediately after the closing is comprised of eight board members, six seats occupied by previous Rigetti board members and one seat being occupied by a previous Supernova representative. The final eighth seat was filled by an individual who did not have ties to either Rigetti or Supernova pre-merger; • Legacy Rigetti management continues to hold executive management roles for the post-combination company and be responsible for the day-to-day Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy Rigetti issuing stock for the net assets of SNII, accompanied by a recapitalization. The primary asset acquired from SNII was cash. Separately, the Company also assumed warrants that were deemed to be derivatives and meet liability classification subject to fair value adjustment measurements upon closing of the Business Combination (the “Closing”). No goodwill or other intangible assets were recorded as a result of the Business Combination. While SNII was the legal acquirer in the Business Combination, because Legacy Rigetti was deemed the accounting acquirer, the historical financial statements of Legacy Rigetti became the historical financial statements of the combined company, upon the consummation of the Business Combination. As a result, the financial statements included in this report reflect (i) the historical operating results of Legacy Rigetti prior to the Business Combination; (ii) the combined results of SNII and Legacy Rigetti following the closing of the Business Combination; (iii) the assets and liabilities of Legacy Rigetti at their historical cost; and (iv) the Company’s equity structure for all periods presented. The equity structure has been retroactively restated in all comparative periods up to the Closing Date, to reflect the number of shares of the Company’s Common Stock, $0.0001 par value per share, issued to Legacy Rigetti shareholders and Legacy Rigetti convertible preferred shareholders in connection with the Business Combination. As such, the shares and corresponding capital amounts and earnings per share related to Legacy Rigetti redeemable convertible preferred stock and Legacy Rigetti Common Stock prior to the Business Combination have been retroactively restated as shares reflecting the exchange ratio established in the Business Combination. The accompanying consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. All dollar amounts in tables, except share and per share amounts, in the notes to the consolidated financial statements are presented in thousands unless otherwise noted. Risks and Uncertainties Based on our forecasts, we believe that our existing cash and cash equivalents and available for sale investments will be sufficient to meet our anticipated operating cash needs for at least the next 12 months from the issuance of these financial statements based on our current business plan and expectations and assumptions considering current macroeconomic conditions.

Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Emerging Growth Company earlier of the date the Company (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, the consolidated financial statements may not be comparable to companies that comply with the new or revised accounting standards as of public company effective dates. Use of Estimates Principals of Consolidation Reclassifications Segments Foreign Currency Comprehensive Loss available-for-sale Cash, Cash Equivalents and Restricted Cash The Company’s restricted cash balance includes cash whose use is limited by contractual provisions. As of December 31, 2022, there was no restricted cash. As of December 31, 2021, restricted cash consists of cash secured as collateral for letters of credit in favor of the Company’s landlord and its corporate credit card program. The following table provides a reconciliation of cash, cash equivalents and restricted cash in the consolidated balance sheets to the total amount shown in the consolidated statements of cash flows: December 31, December 31, Cash $ 21,542 $ 11,729 Cash e 36,346 — Restricted cash — 317 Total cash, cash equivalents and restricted cash $ 57,888 $ 12,046 Investments available-for-sale Accounts Receivable Prepaid Expenses and Other Current Assets Deferred Offering Costs paid-in The LLC was filed with the SEC, there were no shares issued other than the commitment shares referred to in Note 12. As such $0.7 million of the offering costs were classified as deferred offering costs. As of December 31, 2021, the Company had recorded deferred offering costs of $3.4 million, all of which are related to the Business Combination as discussed in Note 3. Property and Equipment, Net Long-lived assets, which consist of property and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset (asset group) may not be recoverable. When such events or changes in circumstances occur, the Company performs an undiscounted cash flow analysis to determine if an impairment exists and, if so, an impairment loss would be recorded based on the excess of the carrying amount of the asset (asset group) over its fair value. During the year ended December 31, 2022 the Company determined there was a triggering event and an undiscounted cash flow analysis was performed. Based on the results of this analysis, the Company’s long-lived assets were not impaired and no impairment charge was recorded. During the 11 months ended December 31, 2021 no triggering events were noted. Goodwill The Company determined a triggering event existed in the fourth quarter of 2022 resulting from the sustained decline in the Company’s stock price. A quantitative impairment test was performed and as a result, the Company recognized a $5.4 million goodwill impairment charge for the year ended December 31, 2022. Deferred Financing Costs debt d b obligation. Public and Private Warrants had 4,450,000 Private Warrants and Public warrants outstanding. Each whole warrant entitles the holder to purchase one share of the Company’s Common Stock at a price of $ per share, subject to adjustments, and will expire after the Business Combination or earlier upon redemption or liquidation. The Private Warrants do not meet the derivative scope exception and are accounted for as derivative liabilities. Specifically, the Private Warrants contain provisions that cause the settlement amounts to be dependent upon the characteristics of the holder of the warrant which is not an input into the pricing of a fixed-for-fixed classified as a liability. Since the Private Warrants meet the definition of a derivative, the Company recorded the Private Warrants as liabilities in the consolidated balance sheet at fair value upon the closing, with subsequent changes in the fair value recognized in the consolidated statements of operations at each reporting date. The fair value of the Private Warrants are measured using the Black-Scholes option-pricing model. The Public Warrants also fail to meet the indexation guidance in ASC 815 and are accounted for as liabilities because they include a provision whereby if there is not an effective registration statement, the warrant holders have a cap of 0.361 shares of Common Stock per warrant (subject to adjustment), on the issuable number of shares in a cashless exercise. Subsequent to the separate listing and trading of the Public Warrants, their fair value has been measured based on the observable listed prices for such warrants. Upon consummation of the Business Combination, the Company recorded a liability related to the Public Warrants of $16.3 million, with an offsetting entry to additional paid-in See Note 13 and 15 for further information on fair value. Derivative Warrant Liabilities Other than the Public and Private Warrants noted above, the Company also issued warrants to Trinity Capital which are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period until exercised. The fair value of the warrant liabilities issued were initially measured using the Black- Scholes model and are subsequently remeasured at each reporting period with changes recorded as a component of other (expense) income in the Company’s consolidated statements of operations. During the year ended December 31, 2022 these warrants were exercised and are no longer outstanding. Earn-Out “Earn-Out These Sponsor Vesting Shares are accounted for as liability classified instruments because the Earn-Out As of December 31, 2022, the Earn-Out Significant inputs into the respective valuation models at March 2, 2022 (the initial recognition) and December 31, 2022 are as follows: Valuation Assumptions Initial Recognition on December 31, 2022 Stock Price $ 9.43 $ 0.73 Simulated trading days 1,198 1,050 Volatility (annual) 30.50 % 109.30 % Risk-free rate 1.74 % 4.04 % Estimated time to expiration (years) 5.000 4.170 Revenue Recognition Revenue from Contracts with Customers ASC 340-40, Other Assets and Deferred The Company recognizes revenue from contracts with • Identify the contract with a customer • Identify the performance obligations in the contract • Determine the transaction price • Allocate the transaction price to the performance obligations in the contract • Recognize revenue when (or as) performance obligations are satisfied The Company generates revenue through its Quantum Computing as a Service (“QCaaS”) and development contracts and other services. Access to Rigetti quantum computing systems can be purchased as a quantum computing subscription, or on a usage basis for a specified quantity of hours. Revenue related to subscription-based access to (“QCaaS”) is recognized over time as access to the systems is provided on a ratable basis over the subscription term, which can range from six months to two years. This time-based input measure of progress provides a faithful depiction of the transfer of the services because the benefits the customer obtains generally equals the benefit from its access to the systems throughout the subscription term. Revenue related to usage-based access to Rigetti quantum computing systems is recognized over time as the systems are accessed using an output method based on compute credit hours expended. This output method provides a faithful depiction of the transfer of the services because the customer has purchased a specified quantity of hours of usage that diminishes each time an hour is expended and therefore each hour of access to the systems is considered a discrete delivery of underlying services in these arrangements. Development contracts are generally multi-year, non-recurring When the Company’s contracts with customers contain multiple performance obligations, the transaction price is allocated on a relative standalone selling price basis to each performance obligation. The Company typically determines standalone selling price based on observable selling prices of our products and services. In instances where standalone selling price is not directly observable, standalone selling price is determined using information that may include market conditions and other observable inputs. Standalone selling price is typically established as a range. In situations in which the stated contract price for a performance obligation is outside of the applicable standalone selling price range and has a different pattern of transfer to the customer than the other performance obligations in the contract, the Company will reallocate the total transaction price to each performance obligation based on the relative standalone selling price of each. The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring goods and services to the customer. Revenue is recorded based on the transaction price, which includes fixed consideration and estimates of variable consideration. The amount of variable consideration included in the transaction price is constrained and is included only to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company’s contracts with customers may include renewal or other options at fixed prices. Determining whether such options are considered distinct performance obligations that provide the customer with a material right and therefore should be accounted for separately requires significant judgment. Judgment is required to determine the standalone selling price for each renewal option to determine whether the renewal pricing is reflective of standalone selling price or is reflective of a discount that would provide the customer with a material right. Based on the Company’s assessment of standalone selling prices, the Company determined that there were no significant material rights provided to its customers requiring separate recognition. The timing of revenue recognition may not align with the right to invoice the customer. The Company records accounts receivable when it has the unconditional right to issue an invoice and receive payment, regardless of whether revenue has been recognized. If revenue has not yet been recognized, a contract liability (deferred revenue) is also recorded. If revenue is recognized in advance of the right to invoice, a contract asset or unbilled receivable is recorded, depending on whether the Company’s right to consideration is considered conditional or unconditional. Unbilled receivables are included within accounts receivable in the consolidated balance sheets. In instances where the timing of revenue recognition differs from the timing of the right to invoice, the Company has determined that a significant financing component generally does not exist. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the products and services and not to receive financing from or provide financing to the customer. Additionally, the Company has elected the practical expedient that permits an entity not to recognize a significant financing component if the time between the transfer of a good or service and payment is one year or less. Payment terms on invoiced amounts are typically net 30 days. The Company does not offer rights of return for its products and services in the normal course of business, and contracts generally do not include service-type warranties that provide any incremental service to the customer beyond providing assurance that the goods and services conform to applicable specifications or customer-specific or subjective acceptance provisions. The Company also excludes from revenue government-assessed and imposed taxes on revenue-generating activities that are invoiced to customers. Costs of Obtaining and Fulfilling Contracts Cost of Revenue related costs, including compensation, bonuses, employee taxes and benefit costs of program management and personnel associated with the delivery of goods and services to customers. Cost of revenue also includes an allocation of facility costs, depreciation and amortization directly related to providing the QCaaS offerings and development contracts and other services.

Potential common shares from stock options, unvested restricted stock units and Common Stock warrants are computed using the treasury stock method, while those from convertible Series C and C-1 if-converted Stock-Based Compensation 4-year change-in-control Compensation expense is based on the grant-date fair value of the awards and recognized over the requisite service period using a straight-line method for awards that have a service only condition. Compensation expense for awards with service and performance and/or market conditions is recognized using a graded vesting method. Compensation expense for RSAs is recognized fully on grant date. Compensation expenses for awards with a market condition are recognized over the requite service period regardless of whether the market condition is met unless the service requirement is not met. The Company has elected to account for forfeitures of employee stock awards as they occur. Fair Value Measurements Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2—Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. Level 3—Inputs are unobservable for the asset or liability. The level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest-level input that is significant to the fair value measurement in its entirety.

Recently Adopted Accounting Pronouncements 2016-0 2, right-of-use The Company adopted Topic 842 effective January 1, 2022, using the modified retrospective transition option of applying the new standard at the adoption date for all leases with an original term greater than 12 months. The Company elected the package of practical expedients requiring no reassessment of (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification of any expired or existing leases, or (iii) initial direct costs for any existing leases. Adoption of the standard had a material impact on the Company’s consolidated balance sheet by recognizing operating lease ROU assets and operating lease liabilities but did not The Company determines if an arrangement includes a lease at inception. Operating leases are included in the Company’s balance sheet as operating lease ROU assets and operating lease liabilities as of December 31, 2022. Operating lease ROU assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value of its lease payments, the Company uses an estimated incremental borrowing rate that is applicable to the Company based on the information available at the later of the lease commencement date, lease modification date, or the date of adoption of Topic 842. The operating lease ROU assets also include any lease payments made less lease incentives. The Company’s leases may include options to extend or terminate the lease, which is considered in the lease term when it is reasonably certain that the Company will exercise any such options. Lease expense is recognized on a straight-line basis over the expected lease term, taking into account adjustments for provisions such as free rent, escalating base monthly rental payments or deferred payment terms such as rent holidays that defer the commencement date of required payments. The Company has elected not to apply the recognition requirements of Topic 842 for short-term leases. The Company considers leases with a term of 12 months or less at the date of commencement to be short-term.

Under the qualitative assessment, management considers relevant events and circumstances including but not limited to macroeconomic conditions, industry and market considerations, overall Company performance and events directly affecting the Company. It was noted during our assessment that the Company has experienced a sustained decline in stock price, however as of November 1, 2022 the Company determined that goodwill was not impaired. Subsequently in December 2022, the Company’s stock price continued to decline, resulting in a triggering event to evaluate goodwill for impairment as of December 31, 2022. As a result, further quantitative analysis was conducted to determine the extent to which, if any, the Company’s carrying value exceeded its fair value as of December 31, 2022. The quantitative analysis used fair value based on market capitalization adjusted for a control premium based on market comparable transactions. This quantitative analysis resulted in the Company’s fair value being significantly below its carrying value, resulting in a non-cash

Debt

Debt	12 Months Ended

Debt	10. DEBT In March 2021, the Company entered into an agreement (the “Loan Agreement”) with Trinity Capital Inc. (“Trinity”) to secure a debt commitment of $12.0 million (the “Tranche A”) which was drawn at the closing. The term loan is collateralized by a first-priority, senior secured interest in substantially all of the Company’s assets. In conjunction with the Loan Agreement, the Company issued Trinity a warrant to purchase shares of Common Stock (the “Trinity Warrants”) which is recorded at fair value using the Black-Scholes model, see Note 15 for the fair value assumptions. The Loan Agreement contains customary representations, warranties and covenants; however, the debt agreement does not include any financial covenants. In May 2021, the debt agreement was modified to increase the overall debt commitment by $15.0 million (the “Tranche B” or the “Amendment”) and $8.0 million of the additional commitment was drawn at the closing and the remaining commitment of $7.0 million was available at the Company’s option at any time through March 10, 2022 subject to certain conditions. The Company drew the $7.0 million in November 2021. In conjunction with the Amendment, the Company cancelled the Initial Warrants and issued 995,099 (783,129 shares post conversion upon the closing of the Business Combination) warrant shares to purchase the Common Stock which was an incremental cost allocated between Tranche A and Tranche B, see Note 13 for further information on these warrants. The Amendment to the debt agreement was considered a modification for accounting purposes. The Company capitalized $2.8 million of debt issuance costs which consist of incremental costs incurred for the lenders and third-party legal firms as well as the fair value of the warrant issued in conjunction with the term loan. Under the Amendment, the maturity date was modified to be the date equal to 48 months from the first payment date of each specific cash advance. Subject to an interest only period of 19 months following each specific cash advance date, the term loan incurs interest at a rate of the greater of 11% or In January 2022, the debt agreement was modified to increase the overall debt commitment by $5.0 million (the “Tranche C” or the “Third Amendment”) which was drawn on January 27, 2022. Subject to an interest only period of 19 months, Tranche C incurs interest at a rate of the greater of 11% and the US Prime Rate plus 7.50% per annum, payable monthly, until the maturity date, February 1, 2026. Other modifications per the amendment included an extension of the requirement to raise an additional $75 million of equity until April 1, 2022, and a defined exit fee for the additional $5.0 million to be at 20% of the advanced funds under the amendment. The company met the requirement to raise additional equity of $75 million through the business combination mentioned in Note 3. The Company paid an exit fee of $ % of the Tranche C amount upon the consummation of the merger. The exit fee was capitalized as a debt issuance cost and is amortized using the effective interest method over the life of Tranche C. The exit fee is not applicable to Tranche A and Tranche B. In conjunction with the amendment, the Company also guaranteed payment of all monetary amounts owed and performance of all covenants, obligations and liabilities. In addition, the Company is required to pay a final payment fee equal to 2.75% of the aggregate amount of all term loan advances. The final payment fee is being accreted and amortized into interest expense using the effective interest rate method over the term of the loan. The effective interest was between 20.75 % The fair value of the debt is classified as Level 2. Given the maturity and variable interest rate on the debt, the book value approximates its fair value. Long term debt and the unamortized discount balances are as follows: December 31, December 31, 2022 2021 Outstanding principal amount $ 30,709 $ 27,000 Add: accreted liability of final payment fee 407 125 Less: unamortized debt discount, long term (990 ) (1,618 ) Less: current portion of long term debt-principal (9,491 ) (1,291 ) Debt—net of current portion $ 20,635 $ 24,216 Current portion of long term debt—principal $ 9,491 $ 1,291 Less: current portion of unamortized debt discount (1,188 ) (716 ) Debt—current portion $ 8,303 $ 575 During the year ended December 31, 2022, the Company recorded interest expense of $ million, which includes the accretion of the end of term liability of $ million, the amortization of commitment fee asset of $ million and the amortization of debt issuance cost of $ million, respectively. The unamortized debt discount of $ million as of December 31, 2022 is offset against the carrying value of the term loan in the consolidated balance sheet. During the 11 months ended December 31, 2021, the Company recorded interest expense of $ million, which includes the accretion of the end of term liability of $ million, the amortization of commitment fee asset of $ million and the amortization of debt issuance cost of $ million. The unamortized debt discount of $ million as of December 31, 2021 is offset against the carrying value of the term loan in the consolidated balance sheet.

WARRANTS As a result of the Business Combination (see Note 3), the Company has retroactively adjusted the number and corresponding strike price of Rigetti warrants outstanding prior to March 2, 2022, the date of the Business Combination, to give effect to the Exchange Ratio used to determine the number of shares of Common Stock into which they were converted. Liability Classified Warrants Public Warrants Each Public Warrant entitles the holder to the right to purchase one share of Common Stock at an exercise price of $11.50 per share. No fractional shares will be issued upon exercise of the Public Warrants. The Company may elect to redeem the Public Warrants subject to certain conditions, in whole and not in part, at a price of $0.01 per Public Warrant if (i) 30 days’ prior written notice of redemption is provided to the holders, and (ii) the last reported sale price of the Company’s Common Stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading Private Warrants The Private Warrants may not be redeemed by the Company so long as the Private Warrants are held by the initial purchasers, or such purchasers’ permitted transferees. The Private Warrants have terms and provisions identical to those of the Public Warrants, including as to exercise price, exercisability and exercise period, except if the Private Warrants are held by someone other than the initial purchasers’ permitted transferees, then the Private Warrants are redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. On August 18, 2022, the Private Placement Warrants were transferred from the initial purchasers to permitted transferees and remain unredeemable by the Company as of December 31, 2022. The fair value of the Private Warrant was measured using the Black Scholes model approach. Significant inputs into the respective models at March 2, 2022 (the initial recognition) and December 31, 2022 are as follows: Valuation Assumptions December 31, Initial Recognition Stock Price $0.73 $9.43 Strike Price $11.50 $11.50 Volatility (annual) 109.26% 30.66% Risk-free rate 4.04% 1.74% Estimated time to expiration (years) 4.172 5.000 Dividend yield —% —% Trinity Warrants The Trinity Warrants were issued in March of 2021 for the purchase of 313,252 shares of Common Stock, and additional warrants to purchase 469,877 shares of Common Stock were issued in connection with the Tranche B Amendment, see Note 10. Therefore, there were total of 783,129 Common Stock warrants issued in conjunction with the Loan and Security Agreement in 2021. The Company utilized a Black-Scholes model to determine the grant date fair value of the warrants which was approximately $2.7 million and was recorded as a debt issuance cost. The outstanding Common Stock warrants were subsequently remeasured at each reporting period using the Black-Scholes models with changes recorded as a component of other income in the Company’s consolidated statement of operations. The liability related The warrant issued in conjunction with the Loan and Security Agreement was classified as a liability under ASC 480, “Distinguishing Liabilities from Equity”. See Deferred Financing Cost disclosure at Note 2 Summary of Significant Accounting Policies. Significant inputs into the Black Scholes model used to value the Trinity Warrant liabilities at June 2, 2022, the exercise date, are as follows: Valuation Assumptions - Trinity Warrant Liability June 2, 2022 Stock price $8.23 Strike price $0.27 Volatility (annual) 105.10% Risk-free rate 2.94% Estimated time to expiration (years) 9.000 Dividend yield —% Equity Classified Warrants Series C Preferred Stock Financing Warrants In conjunction with a prior Series C Preferred Stock Financing the Company issued a total of 10-year capital.

Forward Warrant Agreement	14. FORWARD WARRANT AGREEMENT In connection with the execution of the Merger Agreement in October 2021, Rigetti entered into a warrant subscription agreement (“Forward Warrant Agreement”) with a strategic partner, Ampere Computing LLC (“Ampere”) for the purchase of a warrant for an aggregate purchase price (including amounts from exercise) of $ On June 30, 2022, pursuant to the Warrant Subscription Agreement, the Company issued the warrant to Ampere upon receipt of an aggregate of $5.0 million (including the exercise price), and upon such payment and issuance, 500,000 shares of the Company’s Common Stock vested under the warrant and were immediately exercised by Ampere pursuant to the terms of the warrant. Ampere is required to pay an additional $5.0 million to Rigetti no later than the closing date of the listing of Ampere’s capital stock, provided that if the listing has not occurred by the second anniversary of the Warrant Subscription Agreement, Ampere is not obligated to make the additional payment. Upon the payment of such additional amounts, the warrant will vest and be exercisable with respect to the remaining 500,000 shares underlying the warrant. The Warrant Subscription Agreement further provides that the Company will use commercially reasonable efforts to file a registration statement to register the resale of the remaining shares underlying the warrant. The Company filed a registration statement registering the resale of the initial 500,000 shares issued under the warrant during the year ended December 31, 2022. The Company evaluated the Forward Warrant Agreement as a derivative in conjunction with the guidance of ASC 480, “Distinguishing Liabilities from Equity”. The Company calculated the fair value of the Forward Warrant Agreement by using the Forward Contract Pricing methodology at inception and at December 31, 2022. The fair value of the Forward Warrant Agreement was estimated based on the following key inputs and assumptions 1) Assumed holding period 2) Related risk-free rate and 3) Likelihood of the outcome of the various contingencies outlined below. Based on these inputs and assumption, the Company calculated the fair value of the Forward Warrant Agreement to be a $ derivative asset derivative liability at December 31, 2022 and December 31, 2021, respectively. The Company has included the derivative asset as a forward contract asset and the derivative liability separately in other liabilities (current) on the balance sheet line in the accompanying consolidated balance sheets as of December 31, 2022 and December 31, 2021, respectively. The change in fair value is recorded as part of the general and administrative operating activities in the Company’s consolidated statements of operations.

The carrying values as of December 31, 2022 and December 31, 2021, represent the original principal amounts borrowed less principal payments and debt issuance costs. The fair value of the Public Warrants has been measured based on the observable listed prices for such warrants, a Level 1 measurement. The Company’s money market funds and U.S. Treasury securities are classified within Level I due to the highly liquid nature of these assets with quoted prices in active markets. The investments in available-for-sale The Private Warrants were initially measured at fair value using a Black Scholes model. The Company estimated the fair value of the Forward Warrant Agreement using a forward analysis with unobservable inputs which included selected risk-free rate and probability outcomes. The Company has further discussed the key aspects of the fair value measurements described above in Notes 13 and 14 to the financial statements. The aggregate fair value of the Sponsor Vesting Shares on the Closing date was estimated using a Monte Carlo simulation model. The Company has further discussed the key aspect of the valuation inputs in Note 2 significant accounting policy for Sponsor Earn-Out As of December 31, 2021, the Company recorded a derivative warrant liability for the Trinity Warrants at fair value using a Black-Scholes option model with unobservable inputs including volatility. The Company estimates the volatility of its ordinary share warrants based on implied volatility from the Company’s traded warrants and from historical volatility of select peer company’s ordinary shares that matches the expected remaining life of the warrants. On June 2, 2022, all outstanding Trinity Warrants were exercised into shares of the Company’s Common Stock There have been no changes in fair value measurement techniques (other than the change in valuation assumptions described in Note 1) during the year ended December 31, 2022. There were no transfers between Level 1 or Level 2, or transfers in or out of Level 3 of the fair value hierarchy during the year end December 31, 2022. The fair value estimates are based on pertinent information available to management as of December 31, 2022 and December 31, 2021. Although management is not aware of any factors, other than those noted above, that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for the purpose of these financial statements.

After the Closing Date and consummation of the Business Combination effective March 2, 2022, no additional awards were issued under the 2013 Plan. Awards outstanding under the 2013 Plan will continue to be governed by such plan; however, the Company will not grant any further awards under the 2013 Plan. 2022 Equity Incentive Plan In connection with the Business Combination (Note 3), the shareholders approved the Rigetti Computing, Inc. 2022 Equity Incentive Plan (the “2022 Plan”) in February, 2022, which became effective immediately upon the Closing Date. The 2022 Plan provides for the grant of ISOs, NSOs, stock appreciation rights, restricted stock awards (“RSA”), restricted stock unit awards, performance awards and other forms of awards to employees, directors, and consultants, including employees and consultants of the Company’s affiliates. The aggregate number of shares of common stock reserved for issuance under the 2022 Plan is 18,332,215 shares as of December 31, 2022. As of December 31, 2022, 4,748,116 shares were available for future issuance under the 2022 Plan. The number of shares reserved for issuance under the 2022 Plan will automatically increase on January 1st of each year for a period of nine years commencing on January 1, 2023 and ending on (and including) January 1, 2032, in an amount equal to 5% of the common stock of all classes outstanding on December 31 of the preceding year; provided, however, that the board of directors of the Company may act prior to January 1st of a given year to provide that the increase for such year will be a lesser number of shares of Common Stock. Stock Options A summary of activity related to stock option is summarized as below: Number of Options Weighted- Average Price Weighted- Average Life (in years) Aggregate Intrinsic Outstanding—December 31, 2021 11,468,275 $ 0.36 Granted 1,750,000 $ 0.96 Exercised (2,768,568 ) $ 0.27 Forfeited and expired (1,603,804 ) $ 0.27 Outstanding—December 31, 202 2 8,845,903 $ 0.38 7.2 $ 3,103 Exercisable—December 31, 2022 5,464,027 $ 0.40 7.2 $ 1,780 On December 12, 2022 the Company granted to the CEO an equity award (“CEO award”) under its 2022 Plan that consisted of options to purchase a total of 1,750,000 shares of its common stock with an exercise price of $0.96 per share. Of the total stock options granted to the CEO, 1,250,000 have time-based vesting over 3 years and the remaining 500,000 have market-based vesting conditions. Compensation expense for the CEO award for the year ending December 31, 2022 was insignificant. The weighted-average grant date fair value of options granted during the twelve months ended December 31, 2022 and 11 months ended December 31, 2021 was $0.81 and $3.43 respectively. The total intrinsic value of options exercised during the twelve months ended December 31, 2022 and 11 months ended December 31, 2021 is $9.9 million and $5.7 million, respectively. As of December 31, 2022, there was $2.4 million of unrecognized compensation cost related to non-vested Restricted Stock Units A summary of activity related to RSUs is summarized as below: RSUs Weighted Average Fair Non-vested 5,388,455 $ 3.93 Granted 17,782,607 $ 4.92 Vested (7,007,789 ) $ 4.99 Forfeited (4,830,682 ) $ 5.03 Non-vested 11,332,591 $ 4.36 On March 2, 2022, the performance condition of all outstanding RSUs was met due to the closing of the Business Combination. As a result, the Company recorded a cumulative catch-up Total fair value of the RSUs vested during the twelve months ending December 31, 2022 and 11 months ended December 31, 2021 was $35.0 million and $0 respectively. Stock-based compensation expense related to RSUs granted to employees was $ 42.7 million and $ 0 for the twelve months ended December 31, 2022 and 11 months ended December 31, 2021, respectively. As of December 31, 2022, the unrecognized compensation expense related to unvested RSUs was approximately $ 41.9 million which is expected to be recognized over a weighted-average period of approximately 2.85 years. Restricted Stock Awards During the twelve months ended December 31, 2022, 120,000 restricted stock awards (“RSAs”) were issued and vested immediately on the grant date as part of transaction bonuses in recognition of efforts in connection with the Business Combination. The total compensation expense related to RSAs was $0.6 million for the twelve months ended December 31, 2022. The table below summarizes the total stock-based compensation expenses for the year ended December 31, 2022 and 11 months ended December 31, 2021: Year Ended December 31, 2022 11 Months Ended December 31, 2021 Research and development $ 14,092 $ 975 Selling and marketing expenses 2,109 106 General and administrative expenses 28,611 684 Total stock-based compensation expenses $ 44,812 $ 1,765 Fair Value of Common Stock and Options The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model that uses the assumptions noted in the table below. Expected volatility for the Company’s Common Stock was determined based on an average of the historical volatility of a peer group of similar public companies. The expected term of options granted was calculated using the simplified method, which represents the average of the contractual term of the option and the weighted-average vesting period of the option. The Company uses the simplified method because it does not have sufficient historical option exercise data to provide a reasonable basis upon which to estimate expected term. The assumed dividend yield is based upon the Company’s expectation of not paying dividends in the foreseeable future. The risk-free rate is based upon the U.S. Treasury yield curve in effect at the time of grant for the period equivalent to the expected life of the option. In determining the exercise prices for options granted, the Company’s board of directors has considered the fair value of the Common Stock as of the grant date. Before the Company’s common stock was publicly traded, the fair value of the Common Stock has been determined by the board of directors at each award grant date based upon a variety of factors, including the results obtained from an independent third-party valuation, the Company’s financial position and historical financial performance, the status of technological developments within the Company’s products, the composition and ability of the current engineering and management team, an evaluation or benchmark of the Company’s competition, the current business climate in the marketplace, the illiquid nature of the Common Stock, arm’s-length Stock options issued in 2022, including the options that are based on market conditions, did not have significant impact on the stock-based compensation expense during the year ended December 31, 2022. The range of assumptions used in the Black-Scholes option-pricing model for time based options issued to employees and in Monte Carlo simulation model for market based options during the 12 months ended December 31, 2022 and 11 months ended December 31, 2021 are as follows: 12 Months ended December 31, 2022 11 Months ended 2021 Time based vesting awards Market based vesting Expected volatility 150 % 150 % 46.8 % Weighted-average risk-free interest rate 3.77 % 3.76 % 1.07 % Expected dividend yield 0 % 0 % 0 % Expected term (in years) 5.85 5.0 6.1 years Exercise price/Stock price $ 0.96 $ 0.96 $ 0.21

NET LOSS PER SHARE As a result of the Business Combination (see Note 3), the Company has retroactively adjusted the weighted average shares outstanding prior to March 2, 2022 to give effect to the Exchange Ratio used to determine the number of shares of Common Stock into which they were converted. The following table sets forth the computation of basic and diluted net loss per share of Common Stock for the year ended December 31, 2022 and 11 months ended December 31, 2021: Year Ended 11 Months 2022 2021 Net loss $ (71,521) $ (38,241) Basic and diluted shares Weighted-average Class A Common Stock outstanding 102,300,852 23,337,127 Loss per share for Class A Common Stock — Basic $ (0.70) $ (1.64) — Diluted $ (0.70) $ (1.64) There issuable earn-out these shares have not been met as of December 31, 2022. The weighted-average common shares outstanding for the twelve months ended December 31, 2022 and December 31, 2021 include 2,541,856 and 5,116,058 weighted-average shares of warrants with an exercise price of $0.01, respectively. The Company’s potential dilutive securities, which include stock options, restricted stock units, convertible preferred stock and warrants have been excluded from the computation of diluted net loss per share as the effect would be anti-dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share is the same. The Company excluded the following potential common shares from the computation of diluted net loss per share as of December 31, 2022 and December 31, 2021: December 31, December 31, 2022 2021 Convertible Series C-1 — 23,218,320 Convertible Series C Preferred Stock — 54,478,033 Common Stock Warrants 14,444,127 1,822,319 Stock Options 8,845,903 11,468,227 Restricted Stock Units 11,332,591 — 34,622,621 90,986,899 (1) The number of outstanding shares as of December 31, 2021 have been retrospectively adjusted to reflect the Exchange Ratio.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred income tax assets and liabilities as of December 31, 2022 and December 31, 2021, are as follows: December 31, December 31, Deferred t a Net operating loss carryforwards $ 61,313 $ 46,553 Accruals and reserves 160 147 Stock-based compensation 5,233 744 Research and development credits 11 11 Intangible assets 11,509 32 ROU l 2,507 — Gross deferred assets 80,733 47,487 Deferred t l ROU a (2,289 ) — Depreciation and amortization (2,063 ) (1,420 ) Total deferred tax liabilities (4,352 ) (1,420 ) Total net deferred tax assets 76,381 46,067 Valuation allowance (76,381 ) (46,067 ) Net deferred tax assets $ — $ — The effective tax rate differs from the statutory rate, primarily due to the Company’s history of incurring losses which have not been benefited and other permanent differences.

Accordingly, the net U.S. federal and state deferred tax assets have been fully offset by a valuation allowance. The net change in the total valuation allowance was an increase of approximately $30.3 As of December 31, 2022, the Company had net operating loss carryforwards for federal income tax purposes of $230.9 million, of which $189.4 2035 Utilization of the net operating losses and credits may be subject to substantial annual limitation due to federal and state ownership change limitations provided by the Internal Revenue Code and similar state provisions. Such annual limitations could result in the expiration of the net operating losses and credits before their utilization. The Company has not performed a Section 382 analysis to determine if an ownership change occurred and whether the use of net operating loss carryforwards and credits carryforwards will be limited to offset future taxable income. For financial statement purposes, the Company has included the federal and state net operating losses and credits in the deferred tax assets with a full valuation allowance. The Company files U.S., various state income tax returns as well as foreign income tax returns within Australia, Canada and the United Kingdom with varying statutes of limitations. The tax years from inception in 2013 forward remain open to examination due to the carryover of unused net operating losses and tax credits. The Company had unrecognized tax benefits of $4.7 million as of December 31, 2022 all of which is offset by a full valuation allowance. These unrecognized tax benefits, if recognized, would not affect the effective tax rate. There were no interest or penalties accrued as of December 31, 2022. A reconciliation of the beginning and ending amounts of unrecognized income tax benefits during the year is as follows: Beginning balance at January 1, 2022 $ 4,672 Current year increase (decrease) — Prior year adjustment—increase (decrease) — Ending balance at December 31, 2022 $ 4,672

As such $0.7 million of the offering costs were classified as deferred offering costs. As of December 31, 2021, the Company had recorded deferred offering costs of $3.4 million, all of which are related to the Business Combination as discussed in Note 3.
Property and Equipment, Net	Property and Equipment, Net Long-lived assets, which consist of property and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset (asset group) may not be recoverable. When such events or changes in circumstances occur, the Company performs an undiscounted cash flow analysis to determine if an impairment exists and, if so, an impairment loss would be recorded based on the excess of the carrying amount of the asset (asset group) over its fair value. During the year ended December 31, 2022 the Company determined there was a triggering event and an undiscounted cash flow analysis was performed. Based on the results of this analysis, the Company’s long-lived assets were not impaired and no impairment charge was recorded. During the 11 months ended December 31, 2021 no triggering events were noted.
Goodwill	Goodwill The Company determined a triggering event existed in the fourth quarter of 2022 resulting from the sustained decline in the Company’s stock price. A quantitative impairment test was performed and as a result, the Company recognized a $5.4 million goodwill impairment charge for the year ended December 31, 2022.
Deferred Financing Costs	Deferred Financing Costs debt d b obligation.
Public and Private Warrants	Public and Private Warrants had 4,450,000 Private Warrants and Public warrants outstanding. Each whole warrant entitles the holder to purchase one share of the Company’s Common Stock at a price of $ per share, subject to adjustments, and will expire after the Business Combination or earlier upon redemption or liquidation. The Private Warrants do not meet the derivative scope exception and are accounted for as derivative liabilities. Specifically, the Private Warrants contain provisions that cause the settlement amounts to be dependent upon the characteristics of the holder of the warrant which is not an input into the pricing of a fixed-for-fixed classified as a liability. Since the Private Warrants meet the definition of a derivative, the Company recorded the Private Warrants as liabilities in the consolidated balance sheet at fair value upon the closing, with subsequent changes in the fair value recognized in the consolidated statements of operations at each reporting date. The fair value of the Private Warrants are measured using the Black-Scholes option-pricing model. The Public Warrants also fail to meet the indexation guidance in ASC 815 and are accounted for as liabilities because they include a provision whereby if there is not an effective registration statement, the warrant holders have a cap of 0.361 shares of Common Stock per warrant (subject to adjustment), on the issuable number of shares in a cashless exercise. Subsequent to the separate listing and trading of the Public Warrants, their fair value has been measured based on the observable listed prices for such warrants. Upon consummation of the Business Combination, the Company recorded a liability related to the Public Warrants of $16.3 million, with an offsetting entry to additional paid-in See Note 13 and 15 for further information on fair value.
Derivative Warrant Liabilities	Derivative Warrant Liabilities Other than the Public and Private Warrants noted above, the Company also issued warrants to Trinity Capital which are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period until exercised. The fair value of the warrant liabilities issued were initially measured using the Black- Scholes model and are subsequently remeasured at each reporting period with changes recorded as a component of other (expense) income in the Company’s consolidated statements of operations. During the year ended December 31, 2022 these warrants were exercised and are no longer outstanding.

Revenue Recognition	Revenue Recognition Revenue from Contracts with Customers ASC 340-40, Other Assets and Deferred The Company recognizes revenue from contracts with • Identify the contract with a customer • Identify the performance obligations in the contract • Determine the transaction price • Allocate the transaction price to the performance obligations in the contract • Recognize revenue when (or as) performance obligations are satisfied The Company generates revenue through its Quantum Computing as a Service (“QCaaS”) and development contracts and other services. Access to Rigetti quantum computing systems can be purchased as a quantum computing subscription, or on a usage basis for a specified quantity of hours. Revenue related to subscription-based access to (“QCaaS”) is recognized over time as access to the systems is provided on a ratable basis over the subscription term, which can range from six months to two years. This time-based input measure of progress provides a faithful depiction of the transfer of the services because the benefits the customer obtains generally equals the benefit from its access to the systems throughout the subscription term. Revenue related to usage-based access to Rigetti quantum computing systems is recognized over time as the systems are accessed using an output method based on compute credit hours expended. This output method provides a faithful depiction of the transfer of the services because the customer has purchased a specified quantity of hours of usage that diminishes each time an hour is expended and therefore each hour of access to the systems is considered a discrete delivery of underlying services in these arrangements. Development contracts are generally multi-year, non-recurring When the Company’s contracts with customers contain multiple performance obligations, the transaction price is allocated on a relative standalone selling price basis to each performance obligation. The Company typically determines standalone selling price based on observable selling prices of our products and services. In instances where standalone selling price is not directly observable, standalone selling price is determined using information that may include market conditions and other observable inputs. Standalone selling price is typically established as a range. In situations in which the stated contract price for a performance obligation is outside of the applicable standalone selling price range and has a different pattern of transfer to the customer than the other performance obligations in the contract, the Company will reallocate the total transaction price to each performance obligation based on the relative standalone selling price of each. The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring goods and services to the customer. Revenue is recorded based on the transaction price, which includes fixed consideration and estimates of variable consideration. The amount of variable consideration included in the transaction price is constrained and is included only to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company’s contracts with customers may include renewal or other options at fixed prices. Determining whether such options are considered distinct performance obligations that provide the customer with a material right and therefore should be accounted for separately requires significant judgment. Judgment is required to determine the standalone selling price for each renewal option to determine whether the renewal pricing is reflective of standalone selling price or is reflective of a discount that would provide the customer with a material right. Based on the Company’s assessment of standalone selling prices, the Company determined that there were no significant material rights provided to its customers requiring separate recognition. The timing of revenue recognition may not align with the right to invoice the customer. The Company records accounts receivable when it has the unconditional right to issue an invoice and receive payment, regardless of whether revenue has been recognized. If revenue has not yet been recognized, a contract liability (deferred revenue) is also recorded. If revenue is recognized in advance of the right to invoice, a contract asset or unbilled receivable is recorded, depending on whether the Company’s right to consideration is considered conditional or unconditional. Unbilled receivables are included within accounts receivable in the consolidated balance sheets. In instances where the timing of revenue recognition differs from the timing of the right to invoice, the Company has determined that a significant financing component generally does not exist. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the products and services and not to receive financing from or provide financing to the customer. Additionally, the Company has elected the practical expedient that permits an entity not to recognize a significant financing component if the time between the transfer of a good or service and payment is one year or less. Payment terms on invoiced amounts are typically net 30 days. The Company does not offer rights of return for its products and services in the normal course of business, and contracts generally do not include service-type warranties that provide any incremental service to the customer beyond providing assurance that the goods and services conform to applicable specifications or customer-specific or subjective acceptance provisions. The Company also excludes from revenue government-assessed and imposed taxes on revenue-generating activities that are invoiced to customers.

Compensation expenses for awards with a market condition are recognized over the requite service period regardless of whether the market condition is met unless the service requirement is not met. The Company has elected to account for forfeitures of employee stock awards as they occur.
Fair Value Measurements	Fair Value Measurements Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2—Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. Level 3—Inputs are unobservable for the asset or liability.

Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements 2016-0 2, right-of-use The Company adopted Topic 842 effective January 1, 2022, using the modified retrospective transition option of applying the new standard at the adoption date for all leases with an original term greater than 12 months. The Company elected the package of practical expedients requiring no reassessment of (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification of any expired or existing leases, or (iii) initial direct costs for any existing leases. Adoption of the standard had a material impact on the Company’s consolidated balance sheet by recognizing operating lease ROU assets and operating lease liabilities but did not The Company determines if an arrangement includes a lease at inception. Operating leases are included in the Company’s balance sheet as operating lease ROU assets and operating lease liabilities as of December 31, 2022. Operating lease ROU assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value of its lease payments, the Company uses an estimated incremental borrowing rate that is applicable to the Company based on the information available at the later of the lease commencement date, lease modification date, or the date of adoption of Topic 842. The operating lease ROU assets also include any lease payments made less lease incentives. The Company’s leases may include options to extend or terminate the lease, which is considered in the lease term when it is reasonably certain that the Company will exercise any such options. Lease expense is recognized on a straight-line basis over the expected lease term, taking into account adjustments for provisions such as free rent, escalating base monthly rental payments or deferred payment terms such as rent holidays that defer the commencement date of required payments. The Company has elected not to apply the recognition requirements of Topic 842 for short-term leases. The Company considers leases with a term of 12 months or less at the date of commencement to be short-term.
