Research Alliance Corp. II (RACB) was a blank-check special purpose acquisition company that filed a Form 15-12G with the Securities and Exchange Commission on December 16, 2022, initiating the voluntary termination of its registered securities under Section 12(g) of the Securities Exchange Act of 1934. The filing effectively concluded RACB's life as a public registrant, a procedural step most commonly taken after a SPAC completes a business combination or elects to wind down operations. Backed by the Research Alliance sponsor group, the vehicle was part of the surge in blank-check activity that characterized U.S. capital markets during the 2020–2021 SPAC boom.
