Item 1.01 Entry into a Material Definitive Agreement.

On February 18, 2026, M3-Brigade Acquisition V Corp. (the “Company”) issued a promissory note (the “Note”) to MI7 Sponsor, LLC (the “Sponsor”), the Company’s sponsor, pursuant to which the Company can borrow up to an aggregate principal amount of $2,000,000 from the Sponsor. On February 18, 2026, the Company borrowed $600,000 under the Note. The proceeds of the Note will be used to provide the Company with general working capital.

The Note bears no interest and is payable in full upon the consummation of the Company’s initial business combination (the “Maturity Date”). A failure to pay the principal on the Maturity Date shall be deemed an event of default, in which case the Note may be accelerated. If the Company does not consummate an initial business combination, the Note will be repaid solely to the extent the Company has funds available outside its trust account established in connection with the Company’s initial public offering.

The description of the Note does not purport to be complete and is subject to, and qualified in its entirety by reference to, the Note, a copy of which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.
