Smart Money Convergence

MBUU does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

Boat maker Malibu Boats reported that director Michael J. Connolly notified the board on August 18, 2026 that he won't stand for re-election at the company's 2026 annual meeting of stockholders, and he'll serve out his current term until then. The filing stresses that his decision wasn't due to any disagreement with the company over operations, policies, or practices. Separately, the board voted on August 20 — under Section 3.02 of the company's bylaws — to shrink from nine directors to eight once his seat opens up.
