prospective financial information and specific assertions noted in the Staff&#146;s comment, are, except as described below, the same as the slides in the investor presentation dated October&nbsp;6, 2021 (the &#147;October Presentation&#148;). The
October Presentation was furnished on a Current Report on Form <FONT STYLE="white-space:nowrap">8-K</FONT> and filed as soliciting material pursuant to Rule 425 and Rule <FONT STYLE="white-space:nowrap">14a-12</FONT> of the Securities Exchange Act

(&#147;<B><I>Rigetti</I></B>&#148;). The prospective financial information was prepared for purposes of the Supernova management team&#146;s diligence of the Rigetti business and its growth opportunity as well as the Supernova Board&#146;s
evaluation of the Business Combination in connection with approving the Business Combination and recommending it to the Supernova shareholders for approval. The prospective financial information was also shared with potential investors in connection
with the Company&#146;s confidential private placement of public equities (&#147;<B><I>PIPE Financing</I></B>&#148;). The information in the October Presentation, including the prospective financial information, was made publicly available pursuant
to the contractual obligation set forth in Section&nbsp;7 of the PIPE Financing subscription agreements, which required the Company to publicly disclose all material <FONT STYLE="white-space:nowrap">non-public</FONT> information that it had shared
