Harraden group exits 5% holder status in M3-Brigade (MBAV) 13G/A

Rhea-AI Filing Summary

Harraden Circle investment entities and Frederick V. Fortmiller, Jr. filed Amendment No. 2 to a Schedule 13G for M3-Brigade Acquisition V Corp. They report beneficial ownership of 500,000 shares of Class A common stock, representing 1.74% of the class as of the December 31, 2025 event date.

The shares are directly held across several Harraden funds, with Harraden Circle Investments, LLC, related general partners, and Mr. Fortmiller deemed indirect beneficial owners through their management roles. The group certifies the holdings were not acquired to change or influence control of the company. The amendment states this is an exit filing because their ownership has fallen below 5% of the outstanding Class A shares.

FAQ

What does the MBAV Schedule 13G/A filing by Harraden Circle report?

The filing reports that Harraden Circle entities and Frederick V. Fortmiller, Jr. beneficially own 500,000 MBAV Class A shares, or 1.74% of the class. It amends prior disclosures and confirms their stake has fallen below the 5% reporting threshold.

Who are the reporting persons in the MBAV Schedule 13G/A Amendment No. 2?

Reporting persons are Harraden Circle Investments, LLC, several affiliated Harraden Circle limited partnerships and general partners, and Frederick V. Fortmiller, Jr. They are linked through investment manager and general partner roles that give them indirect beneficial ownership of the MBAV Class A shares.

How many M3-Brigade Acquisition V Corp. shares do the Harraden entities own?

They report beneficial ownership of 500,000 shares of MBAV Class A common stock. This stake represents 1.74% of the outstanding Class A shares, with voting and dispositive power shared among the Harraden entities and Frederick V. Fortmiller, Jr.

Why is this MBAV Schedule 13G/A described as an exit filing?

It is described as an exit filing because the reporting group states it has ceased to be beneficial owner of more than 5% of MBAV’s Class A common stock. Their current reported holding of 1.74% is below the 5% threshold that normally triggers ongoing Schedule 13D or 13G reporting.

Are the Harraden Circle holdings in MBAV intended to influence control of the company?

The filers certify the MBAV securities were not acquired and are not held for the purpose of changing or influencing control of the issuer. They also state the holdings are not part of any transaction intended to affect control, other than activities tied to proxy nomination rules.

Which Harraden funds directly hold MBAV shares according to the Schedule 13G/A?

Direct beneficial owners are Harraden Circle Investors, LP, Harraden Circle Special Opportunities, LP, Harraden Circle Strategic Investments, LP, and Harraden Circle Concentrated, LP. Other Harraden entities and Frederick V. Fortmiller, Jr. may be deemed indirect beneficial owners through general partner and investment manager roles.
