Warrants |
Warrants | (7) Warrants ​ Each whole Public Warrant and Private Warrant entitles the holder to purchase one share of Common Stock at a price of $11.50 per whole share, subject to adjustment as discussed below. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of shares of Common Stock. The warrants will expire on March 2, 2027 at 5:00 p.m., New York City time, or earlier upon redemption or liquidation. ​ Public Warrants ​ When the price per share of the Company’s Common Stock equals or exceeds $18.00, the Company may redeem the outstanding warrants in whole and not in part, at a price of $0.01 per warrant as follows (except as described herein with respect to the Private Warrants):
| ● | upon a minimum of 30 days’ prior written notice of redemption to each warrant holder; and
| ● | if, and only if, the closing price of the shares of the Company’s Common Stock equals or exceeds $18.00 per share on the trading day prior to the date on which the Company sends the notice of redemption to the warrant holders.
​ If the foregoing conditions are satisfied and the Company issues a notice of redemption of the warrants, each warrant holder will be entitled to exercise its warrant prior to the scheduled redemption date. Any such exercise would not be done on a “cashless” basis and would require the exercising warrant holder to pay the exercise price in cash for each warrant being exercised. The price of the shares of the Company’s Common Stock may fall below the $18.00 redemption trigger price as well as the $11.50 warrant exercise price after the redemption notice is issued. ​ When the price per share of the Company’s Common Stock equals or exceeds $10.00, the Company may redeem the outstanding warrants in whole and not in part, at a price of $0.10 per warrant as follows (except as described herein with respect to the Private warrants):
| ● | upon a minimum of 30 days’ prior written notice of redemption provided that holders will be able to exercise their warrants on a cashless basis prior to redemption as described below; and
| ● | if, and only if, the closing price of the Company’s Common Stock equals or exceeds $10.00 per share on the trading day prior to the date on which the Company sends the notice of redemption to the warrant holders.
​ Beginning on the date the notice of redemption is given until the warrants are redeemed or exercised, holders may elect to exercise their warrants on a cashless basis and could potentially receive up to a maximum of 0.361 shares of Common Stock per warrant or a minimum of 0.034 shares of Common Stock per warrant. The number of shares of Common Stock that a warrant holder will ultimately receive upon a cashless exercise in connection with a redemption by the Company, is based on the fair market value of the Company’s Common Stock on the redemption date, determined based on the volume weighted average price of the Company’s Common Stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of the warrants, and the number of months that the corresponding redemption date precedes the expiration date of the warrants, as set forth in a table in the warrant agreement. ​ As of September 30, 2025 and December 31, 2024, Public Warrants issued and outstanding were 11,704,886 and 11,082,870, respectively (Refer to Note 5 for fair value measurement). The Public Warrants are accounted for as a derivative liability. The fair value of the Public Warrants is measured at each reporting period based on the listed price for the warrants, with subsequent changes in the fair value recognized in the condensed consolidated statement of operations at each reporting date. ​ During the three and nine months ended September 30, 2025, the number of Public Warrants exercised, each for one share of Common Stock in exchange for cash proceeds of $11.50 per share, were 221,118 and 260,912, respectively. During the three and nine months ended September 30, 2025, the proceeds from the warrant exercises totaled $2.5 million and $3.0 million, respectively, and the underlying Public Warrant derivative liabilities on their respective exercise dates totaled $1.3 million and $1.6 million, respectively. The proceeds from the warrant exercises and the underlying Public Warrant derivative liabilities on the exercise dates were recorded to par value of Common Stock and additional paid-in capital. ​ The calculated fair value of the derivative liability for the Public Warrants as of September 30, 2025 and December 31, 2024 were $214.3 million and $70.3 million, respectively. The change in the fair value of the Public Warrants included in the condensed consolidated statement of operations during the three and nine months ended September 30, 2025 was a loss of $162.8 million and $134.0 million, respectively. The change in the fair value of the Public Warrants included in the condensed consolidated statement of operations during the three and nine months ended September 30, 2024 was a gain of $0.5 million and $0.4 million, respectively. ​ Subsequent to September 30, 2025 and through November 6, 2025, the Company received proceeds of $46.5 million from the exercise of 4,042,099 Public Warrants. ​ Private Warrants ​ The Private Warrants have terms and provisions identical to those of the Public Warrants, including as to exercise price, exercisability and exercise period, except that if the Private Warrants are held by the initial purchasers, or such purchasers’ permitted transferees, then the Private Warrants are not redeemable by the Company and may be exercised for cash or on a cashless basis. If the Private Warrants are held by someone other the initial purchasers or such purchasers permitted transferees, then the Private Warrants become Public Warrants and are redeemable by the company and exercisable by such holders on the same basis as the Public Warrants. ​ As of September 30, 2025 and December 31, 2024, Private Warrants issued and outstanding were 1,109,174 and 1,992,102, respectively (Refer to Note 5 for fair value measurement). The Private Warrants are accounted for as a derivative liability. The fair value of the Private Warrants is determined using the Black-Scholes option-pricing model, with subsequent changes in the fair value recognized in the condensed consolidated statements of operations at each reporting date. ​ The calculated fair value of the derivative liability for the Private Warrants as of September 30, 2025 and December 31, 2024 was $26.4 million and $22.8 million, respectively. The change in the fair value of Private Warrants included in the condensed consolidated statements of operations during the three and nine months ended September 30, 2025 was a loss of $19.1 million and $15.3 million, respectively. The change in the fair value of the Private Warrants included in the condensed consolidated statements of operations during the three and nine months ended September 30, 2024 was a gain of $0.7 million and $0.3 million, respectively. ​ Significant inputs into the Black-Scholes option-pricing models used to value the Private Warrants at September 30, 2025 and December 31, 2024 are as follows: ​

​ Equity Classified Warrants ​ Series C Preferred Stock Financing Warrants ​ During 2020, a subsidiary of Legacy Rigetti issued and sold an aggregate of 54.5 million shares of its Series C Preferred Stock at a purchase price of $1.15 per share, for an aggregate purchase price of $56.2 million (the “Series C Preferred Stock Financing”). In conjunction with the Series C Preferred Stock Financing, the Company issued a total of 5,248,183 warrants to purchase Class A Common Stock to the Series C investors (the “Series C Warrants”). The Series C Warrants have a $0.01 per share exercise price and a 10-year term to expiration. The Series C Warrants can be exercised for cash or on a cashless basis. The Company determined that the Series C Warrants met the requirements for equity classification under ASC 480 and ASC 815. ​ The Company estimated the fair value of the Series C warrants using the Black-Scholes model and allocated approximately $1.2 million in proceeds from the Series C Preferred Stock to the value of the Series C Warrants on a relative fair value basis, which was recorded to additional paid in capital. The Series C Warrants were assumed by the Company in connection with the Business Combination. ​ The number of Series C Warrants exercised during the three and nine months ended September 30, 2025 were zero and 16,682, respectively. The proceeds from the warrant exercises were recorded to par value of Common Stock and additional-paid-in capital. As of September 30, 2025 and December 31, 2024, Series C Warrants issued and outstanding were 777,118 and 793,800, respectively. ​ Customer Warrant ​ In February 2020, the Company issued a warrant to purchase shares of its Class A Common Stock to a customer in conjunction with a revenue arrangement (the “Customer Warrant”). The Customer Warrant was assumed by the Company in connection with the Business Combination and converted into a warrant to purchase 2,680,607 shares of Common Stock. The Customer Warrant has an exercise price of $1.152 per share and has a 10-year term to expiration. The Customer Warrant vests upon the achievement of certain performance conditions (i.e., sales milestones) defined in the agreement, and upon a change of control, either 50% or 100% of the then unvested Customer Warrant will become fully vested, dependent on the acquiring party in the change of control transaction. The Customer Warrant can be exercised for cash or on a cashless basis. ​ The Company followed the guidance in ASC 718 and ASC 606 for the accounting of non-cash consideration payable to a customer. The Company determined that the Customer Warrant met the requirements for equity classification under ASC 718 and measured the Customer Warrant based on its grant date fair value, estimated to be $0.2 million. The Company recorded this amount as a deferred asset and additional paid in capital as of the issuance date, as the Company believes it is probable that all performance conditions (i.e., sales milestones) in the Customer Warrant will be met. As of September 30, 2025 and December 31, 2024, the deferred asset balance outstanding is approximately $0.1 million, respectively, which will be recognized as a reduction in revenue in future periods. ​ The vesting status of the Customer Warrant is as follows: ​
​ | ​ | ​ | ​ | ​
​ |  | September 30, 2025 |  | December 31, 2024
Vested Customer Warrant shares |  | 1,340,297 |  | 1,340,297
Unvested Customer Warrant shares |  | 1,340,310 |  | 1,340,310
​ |  | 2,680,607 |  | 2,680,607
