Description of Business

Description of Business	6 Months Ended
	Jun. 30, 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 Cloud Services (“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 Combinations. 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; and • Legacy Rigetti management continues to hold executive management roles for the post-combination company and be responsible for the day-to-day operations. 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 related to the cash amounts that was assumed at historical costs. 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 unaudited condensed 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”) regarding interim financial reporting. All intercompany transactions and balances have been eliminated in consolidation. All dollar amounts, except share and per share amounts, in the notes are presented in thousands, unless otherwise specified. The condensed consolidated balance sheet as of December 31, 2021, included herein, was derived from the audited consolidated financial statements as of that date, but does not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The interim results are not necessarily indicative of the results for any future interim period or for the entire year. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes included as Exhibit 99.1 to the Company’s Current Report on Form 8-K, Risks and Uncertainties — The Company is subject to a number of risks similar to those of other companies of similar size in its industry, including, but not limited to, the need for successful development of products, the need for additional capital (or financing) to fund operating losses, competition from substitute products and services from larger companies, protection of proprietary technology, patent litigation, dependence on key individuals, and risks associated with changes in information technology. COVID-19 COVID-19. COVID-19 COVID-19 Change in Fiscal Year — In October 2021, the board of directors of Rigetti approved a change to Rigetti’s fiscal year-end from January 31 to December 31, effective December 31, 2021. The Company believes the year-end change is important and useful to its financial statement users to allow for increased comparability with its industry peers. As a result of this change, the Company’s fiscal year now begins on January 1 and ends on December 31 of each year, starting on January 1, 2022. Year-over-year quarterly financial data has been and will continue to be recast to be comparative with the new fiscal quarter ends in the new fiscal year.

Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Emerging Growth Company — Following the Business Combination, the Company qualifies as an emerging growth company (‘‘EGC’’) as defined in the Jumpstart our Business Startups (‘‘JOBS’’) Act. The JOBS Act permits companies with EGC status to take advantage of an extended transition period to comply with new or revised accounting standards, delaying the adoption of these accounting standards until they would apply to private companies. The Company intends to use this extended transition period to enable us to comply with new or revised accounting standards that have different effective dates for public and private companies until the 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. The Company anticipates that it will remain an EGC under the JOBS Act until the earliest of (a) the last day of Rigetti’s first fiscal year following the fifth anniversary of the completion of SNII’s initial public offering, (b) the last date of Rigetti’s fiscal year in which Rigetti has total annual gross revenue of at least $1.07 billion, (c) the date on which Rigetti is deemed to be a “large accelerated filer” under the rules of the SEC with at least $700.0 million of outstanding securities held by non-affiliates non-convertible Use of Estimates Reclassifications Deferred Offering Costs paid-in The Company incurred $0.8 million and $0 of offering costs for both the three and six months ended June 30, 2022 and 2021, respectively, which related to filing new registration statements with the SEC after the close of the Business Combination. These costs are incremental to those disclosed in Note 3. As the shares for which the registrations statements were filed were issued as of June 30, 2022, the Company recorded the costs as a reduction to additional paid-in Deferred Financing Costs Segments Foreign Currency Comprehensive Loss non-owner Cash and 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.

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 option-pricing Subsequent to the separate listing and trading of the Public Warrants the fair value of the Public Warrants has been measured based on the observable listed prices for such warrants and the fair value of the Private Warrants are measured using an option pricing model. On the consummation of the Business Combination, the Company recorded a liability related to the Private Warrants of $9.2 million, with an offsetting entry to additional paid-in three an d Similarly, on 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 three and Derivative Warrant Liabilities — The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 815, “Derivatives and Hedging” (“ASC 815”) at the initial recognition. Other than the Public and Private Warrants noted above, the company also has other warrants issued and outstanding 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 will be subsequently remeasured at each reporting period with changes recorded as a component of other income in the Company’s consolidated statements of operations. Derivative warrant liabilities are classified as non-current Earn-Out Earn-Out These Sponsor Earn-Out Earn-Out Earn-Out Earn-Out Earn-Out million and $17.7 million are included in gain on fair value change, net in the condensed consolidated statements of operations for the three and six months ended June 30, 2022.

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.

As a result of the Business Combination, among other things (1) all outstanding shares of Legacy Rigetti Common Stock as of immediately prior to the Closing (including Legacy Rigetti Common Stock resulting from the Legacy Rigetti Preferred Stock Conversion), were exchanged at an exchange ratio of 0.7870 (the “Exchange Ratio”) for an aggregate of 78,959,579 shares of Common Stock; (2) each warrant to purchase Legacy Rigetti Common Stock converted into a warrant to purchase shares of Common Stock (“Assumed Warrant”), with each Assumed Warrant subject to the same terms and conditions as were applicable to the original Legacy Rigetti warrant and having an exercise price and number of shares of Common Stock purchasable based on the Exchange Ratio and other terms contained in the Merger Agreement; (3) each option to purchase Legacy Rigetti Common Stock converted into an option to purchase shares of Common Stock (“Assumed Option”), with each Assumed Option subject to the same terms and conditions as were applicable to the original Legacy Rigetti option and with an exercise price and number of shares of Common Stock purchasable based on the Exchange Ratio and other terms contained in the Merger Agreement, and; (4) each Legacy Rigetti restricted stock unit award converted into a restricted stock unit award to receive shares of Common Stock (“Assumed RSU Award”), with each Assumed RSU Award subject to the same terms and conditions as were applicable to the Legacy Rigetti restricted stock unit award, and with the number of shares of Common Stock to which the Assumed RSU Award converted based on the Exchange Ratio and other terms contained in the Merger Agreement. In connection with the execution of the Merger Agreement, SNII entered into a sponsor support agreement (the “Sponsor Support Agreement”) with the Sponsor, Legacy Rigetti and SNII’s directors and officers.

Financing Arrangements	6. FINANCING ARRANGEMENTS Loan and Security Agreement 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 9 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) 9 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 of greater of 11% and the US Prime Rate plus 7.50% per annum, payable monthly. The Term Loan includes certain negative covenants, primarily consisting of restrictions on the Company’s ability to incur indebtedness, pay dividends, execute fundamental change transactions, and other specified actions. 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 17.83 – 23.70% for all tranches of the debt as of June 30, 2022. 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 Other modifications per the amendment included an extension of the requirement to raise an additional $75 million of equity and a defined exit fee for the additional $5.0 million to be at 20% of the advanced funds under the amendment. Tranche C amount upon the consummation of a merger. 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.

WARRANTS As a result of the Business Combination (see Note 3), the Company has retroactively adjusted the Rigetti warrants outstanding and corresponding strike price 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. 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. As of June 30, 2022, there were 4,450,000 Private Warrants issued and outstanding. 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 June 30, 2022 are as follows: Valuation Assumptions Initial Recognition June 30, 2022 Stock Price $ 9.43 $ 3.67 Strike Price $ 11.50 $ 11.50 Volatility (annual) 29.50 % 56.00 % Risk-free rate 1.74 % 3.01 % Estimated time to expiration (years) 5 4.672 Dividend yield — % — % Trinity Warrants The Trinity Warrants were issued in March of 2021 for warrants to purchase 313,252 shares of common stock, and additional warrants to purchase shares of common stock were issued in connection with the Tranche B Amendment, see Note 6. Therefore, there were total o f common stock warrants issued in conjunction with the Loan and Security Agreement in 2021.

The Company assessed the materiality of the error, both quantitatively and qualitatively, in accordance with the SEC’s Staff Accounting Bulletin No. 99, and concluded that the error was not material to any of its previously reported financial statements based upon both quantitative and qualitative aspects of the error. The Company recorded the following adjustments to correct the prior interim period error in the financial statements as of and for the period ended June 30, 2022 such that the consolidated balance sheet and the year-to-date consolidated statement of operations appropriately reflect the accounting impacts of the related transactions . • Reduced Derivative Warrant Liabilities by $1.3 million and increased the Change in Fair Value of Derivative Warrant Liabilities by $1.3 million The warrant liability balance taking into account the above adjustment was $6.4 million as of June 2, 2022, at which time all outstanding Trinity Warrants o were exercised into shares of the Company’s Common Stock.

Forward Warrant Agreement	10. FORWARD WARRANT AGREEMENT In connection with the execution of the Merger Agreement in October 2021 (See Note 1), Rigetti entered into a warrant subscription agreement (“Forward Warrant Agreement”) with a strategic partner , Ampere Computing LLC (“Ampere”) The purchase of the warrant was conditioned upon, among other things, the consummation of the Business Combination and the entry into a collaboration agreement between Rigetti and Ampere. The parties entered into the collaboration agreement in January 2022. Ampere was required to p million to Rigetti no later than the later of (i) the Closing and (ii) June 30, 2022. 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, 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 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 and the Company is not obligated to issue the warrants. 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 shares issued or issuable pursuant to the warrant and upon such payment the warrant will vest and be exercisable by Ampere with respect to shares of Common Stock pursuant to the terms of the warrant. The Company evaluated the Forward Purchase Agreement as a derivative in conjunction with the guidance of ASC 480, “Distinguishing Liabilities from Equity”. The Company calculated fair value of the Forward Purchase Agreement by using the Forward Contract Pricing methodology at inception and at the end of June 30, 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 contract to be a $1.5 million derivative asset and a million) derivative liability at June 30, 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 in the accompanying consolidated balance sheets as of June 30, 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 condensed consolidated statements of operations. The following table represents key valuation assumptions as of the quarter ended June 30, 2022. Key Valuation Assumptions Holding period (in years) 0.000 - 0.628 Risk free rate 0.00% - Probability of occurring the contingency 50% - 100% Underlying value per share $3.39 - $3.67 The fair value of the Forward Purchase Agreement was determined prior to vesting and exercise of the warrants into shares of Company Common Stock upon Ampere’s payment of million on June 30, 2022 using the share value at opening market price on June 30, 2022. The fair value of the unexercised Forward Award Agreement was determined using the market close value on June 30, 2022.

Fair Value Measurements

Fair Value Measurements	11. FAIR VALUE MEASUREMENTS The Company reports all financial assets and liabilities and nonfinancial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1—Inputs are quoted prices (unadjusted) 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 inputs 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. The fair value measurements of financial assets and liabilities that are measured at fair value at June 30, 2022 and December 31, 2021 are as follows: June 30, 2022 Level 1 Level 2 Level 3 (In Thousands) Assets: Forward Warrant Agreement $ — $ — $ 1,543 Total Assets $ — $ — $ 1,543 Liabilities: Derivative warrant liability-Private Warrants — — 3,338 Derivative warrant liability-Public Warrants 5,606 — — Earn-out — — 8,925 Total Liabilities $ 5,606 $ — $ 12,263 December 31, 2021 Level 1 Level 2 Level 3 (In Thousands) Liabilities: Derivative warrant liability—Trinity Warrants — 4,355 Forward warrant agreement — — 230 Total Liabilities — — 4,585 As of June 30, 2022, the Company has recorded the following financial instruments subject to fair value measurements: 1) Derivate warrant liabilities—Public Warrants liability and Private Warrants, 2) Forward Warrant Agreement, and 3) Earnout liability. The fair value of the Public Warrants has been measured based on the observable listed prices for such warrants, a Level 1 measurement. All other financial instruments are classified as Level 3 liabilities as they all include unobservable inputs. 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 9 and 10 to the financial statements. The aggregate fair value of the Sponsor Earn-Out Earn-Out As of December 31, 2021, the Company recorded a derivative warrant liability – Trinity Warrants which was fair valued based on a Black-Scholes option model with unobservable inputs which included 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 during the three and six months ended June 30, 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 three and six months ended June 30, 2022.

The total intrinsic value of options exercised during the six months ended June 30, 2022 and June 30, 2021 is As of June 30, 2022, there was $1.9 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 Value Per Share Balance at December 31, 2021 5,388,455 Granted 9,885,413 $ 4.89 Vested (2,630,699 ) Forfeited (792,643 ) Balance at June 30, 2022 11,850,526 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 six months ending June 30, 2022 and 2021 was $12.9 million and $0 respectively. Stock-based compensation expense related to RSUs granted to employees was $10.7 million and $21.9 million for the three and six months ended June 30, 2022, respectively. Stock-based compensation expense was $0 for the three and six months ended June 30, 2021. As of June 30, 2022, the unrecognized compensation expense related to unvested RSUs was approximately $49.1 million which is expected to be recognized over a weighted-average period of approximately 2.24 years. Restricted Stock Awards During the first six months ended June 30, 2022, 120,000 shares 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 The table below summarizes the total stock compensation expenses for the three and six months ended June 30, 2022 and 2021 (in thousands): 3 Months Ended June 30, 6 Months Ended June 30, 2022 2022 Research and development $ 2,209 $ 4,598 Sales and marketing expenses 256 697 General and administrative expenses 8,576 17,227 Total Stock Compensation Expenses $ 11,041 $ 22,522 3 Months Ended June 30, 6 Months Ended June 30, 2021 2021 Research and development $ 299 $ 638 Sales and marketing expenses 29 61 General and administrative expenses 193 419 Total Stock Compensation Expenses $ 521 $ 1,118 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. 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 The Company did not grant any stock option awards during the six months ended June 30, 2022. The range of assumptions used in the Black-Scholes option-pricing model for options issued to employees during the six months ended June 30, 2021, are as follows: June 30, 2021 Expected volatility 46.8 % Weighted-average risk-free interest rate 1.07 % Expected dividend yield 0 % Expected term (in years) 6.1 years Exercise price $ 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 three and six months ended June 30, 2022, and 2021 (in thousands, except for share and per share data): Three Months Ended June 30, 2022 2021 Net Loss $ (9,974 ) $ (10,074 ) Basic and diluted shares Weighted-average Class A Common Stock outstanding 114,096,390 21,977,123 Loss per share for Class A Common Stock — Basic $ (0.09 ) $ (0.46 ) — Diluted $ (0.09 ) $ (0.46 ) Six Months Ended June 30, 2022 2021 Net Loss $ (20,444 ) $ (17,861 ) Basic and diluted shares Weighted-average Class A Common Stock outstanding 84,060,966 21,912,665 Loss per share for Class A Common Stock — Basic $ (0.24 ) $ (0.82 ) — Diluted $ (0.24 ) $ (0.82 ) There are 2,683,830 and 3,326,508 for the three and six months ended June 30, 2022, respectively, and 5,237,367 and 5,245,876 w 0.01 f 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 weighted average potential common shares from the computation of diluted net loss per share as of June 30, 2022 and June 30, 2021: June 30, 2022 2021 Convertible Series C-1 — 23,218,418 Convertible Series C Preferred Stock (1) — 54,478,261 Common Stock Warrants (1)(2) 14,176,066 1,890,514 Stock Options (1) 9,482,711 12,795,605 Restricted Stock Units 11,850,526 — 35,509,303 92,382,798 (1) The number of outstanding shares as of June 30, 2021 have been retrospectively adjusted to reflect the Exchange Ratio.

Emerging Growth Company	Emerging Growth Company — Following the Business Combination, the Company qualifies as an emerging growth company (‘‘EGC’’) as defined in the Jumpstart our Business Startups (‘‘JOBS’’) Act. The JOBS Act permits companies with EGC status to take advantage of an extended transition period to comply with new or revised accounting standards, delaying the adoption of these accounting standards until they would apply to private companies. The Company intends to use this extended transition period to enable us to comply with new or revised accounting standards that have different effective dates for public and private companies until the 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. The Company anticipates that it will remain an EGC under the JOBS Act until the earliest of (a) the last day of Rigetti’s first fiscal year following the fifth anniversary of the completion of SNII’s initial public offering, (b) the last date of Rigetti’s fiscal year in which Rigetti has total annual gross revenue of at least $1.07 billion, (c) the date on which Rigetti is deemed to be a “large accelerated filer” under the rules of the SEC with at least $700.0 million of outstanding securities held by non-affiliates non-convertible

Derivative Warrant Liabilities	Derivative Warrant Liabilities — The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 815, “Derivatives and Hedging” (“ASC 815”) at the initial recognition. Other than the Public and Private Warrants noted above, the company also has other warrants issued and outstanding 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 will be subsequently remeasured at each reporting period with changes recorded as a component of other income in the Company’s consolidated statements of operations.

Revenue Recognition	Revenue Recognition 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.
