The securities to be registered hereby
are the units, Class A ordinary shares, par value $0.0001 per share, and warrants to purchase Class A ordinary shares of M3-Brigade Acquisition
VI Corp. (the “Registrant”). The description of the units, Class A ordinary shares and warrants set forth under the heading
“Description of Securities” in the Registrant’s prospectus forming a part of its Registration Statement on Form S-1
(File No. 333-289225), originally filed with the U.S. Securities and Exchange Commission on August 4, 2025, as thereafter amended and
supplemented from time to time (the “Registration Statement”), to which this Form 8-A relates is incorporated by reference
herein. Any form of prospectus or prospectus supplement to the Registration Statement that includes such descriptions and that are subsequently
filed are hereby also incorporated by reference herein.

Item 2.

Pursuant to the Instructions as to
Exhibits for Form 8-A, no exhibits are required to be filed, because no other securities of the Registrant are registered on The Nasdaq
Stock Market LLC, and the securities registered hereby are not being registered pursuant to Section 12(g) of the Securities Exchange Act
of 1934, as amended.
