(To Prospectus dated April 14, 2023)






This prospectus supplement updates and supplements the prospectus, dated April 14, 2023 (as supplemented to date, the “Prospectus”), which forms a part of our registration statement on Form S-1 (No. 333-266810). This prospectus supplement is being filed to update and supplement the information in the Prospectus with the information contained in our Current Report on Form 8-K filed with the Securities and Exchange Commission on July 13, 2023 (the “Current Report”). Accordingly, we have attached the Current Report to this prospectus supplement.

The Prospectus and this prospectus supplement relate to the offer and sale from time to time by Ampere Computing LLC or its permitted transferees (“Ampere” or the “selling stockholder”) of up to 500,000 shares (the “Shares”) of common stock, par value $0.0001 (the “common stock”), of the Company, issued upon the exercise of the vested portion of that certain warrant issued to the selling stockholder (the “Ampere Warrant”) pursuant to the warrant subscription agreement, dated as of October 6, 2021, by and between Legacy Rigetti (as defined below) and Ampere (the “Warrant Subscription Agreement”), for an aggregate purchase price (including amounts for exercise) of $10,000,000, or $10.00 per share. The Shares consist of 500,000 outstanding shares of common stock issued in connection with the exercise of the vested portion of the Ampere Warrant and receipt by the Company of an aggregate $5,000,000 (including aggregate exercise price).

The selling stockholder may offer, sell or distribute all or a portion of the Shares publicly or through private transactions at prevailing market prices or at negotiated prices. We will not receive any of the proceeds from such sales of the Shares.

We will bear all costs, expenses and fees in connection with the registration of these Shares, including with regard to compliance with state securities or “blue sky” laws. The selling stockholder will bear all commissions and discounts, if any, attributable to their sale of Shares. See the section entitled “Plan of Distribution.”

This prospectus supplement updates and supplements the information in the Prospectus and is not complete without, and may not be delivered or utilized except in combination with, the Prospectus, including any amendments or supplements thereto. This prospectus supplement is qualified by reference to the Prospectus, including any amendments or supplements thereto, except to the extent that the information in this prospectus supplement updates and supersedes the information contained therein.

The common stock is listed on The Nasdaq Capital Market (“Nasdaq”) under the symbol “RGTI.” On July 12, 2023, the last reported sales price of the common stock as reported on Nasdaq was $1.74 per share.

We are an “emerging growth company” as defined under U.S. federal securities laws and, as such, have elected to comply with reduced public company reporting requirements. The Prospectus complies with the requirements that apply to an issuer that is an emerging growth company.



Investing in our securities involves a high degree of risks. You should review carefully the risks and uncertainties described in the section titled “Risk Factors” beginning on page 16 of the Prospectus, and under similar headings in any amendments or supplements to the Prospectus.



Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities, or passed upon the accuracy or adequacy of the Prospectus or this prospectus supplement. Any representation to the contrary is a criminal offense.



The date of this prospectus supplement is July 13, 2023.

Item 8.01

Other Events.

As previously disclosed, on January 25, 2023, Rigetti Computing, Inc. (the “Company”) received a letter from the Listing Qualifications Department of The Nasdaq Stock Market, LLC (“Nasdaq”) indicating that, based on the closing bid price for the previous 30 consecutive business days, the listing of the Company’s common stock was not in compliance with Nasdaq Listing Rule 5550(a)(2) to maintain a minimum bid price of $1.00 per share (the “Bid Price Rule”). Under Nasdaq Listing Rule 5810(c)(3)(A), the Company had a period of 180 calendar days, or until July 24, 2023, to regain compliance.

On July 12, 2023, the Company received notification from Nasdaq confirming that for the period from June 27, 2023 to July 11, 2023 the closing bid price of the Company’s common stock had been at $1.00 or greater and that accordingly, the Company has regained compliance with the Bid Price Rule and the matter is now closed.


Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.

Dated: July 13, 2023
