Brookfield Business (BBU) Director Mackenzie Exchanges Shares

What Happened

Mackenzie Donald William, a director of Brookfield Business Corp (BBU), recorded dispositions on March 27, 2026 totaling 20,145 BBU-related units/shares: 13,430 (disposition to issuer) and 6,715 (disposition reported as derivative). No cash price or total dollar value is reported on the Form 4.
These were not ordinary open‑market sales but transfers to the issuer under a court‑approved plan of arrangement that converted BBU non‑voting limited partnership units and BBHC exchangeable shares into class A subordinated voting shares of the Corporation on a one‑for‑one basis. This filing represents the BBU Units and BBHC Exchangeable Shares transacted pursuant to that Arrangement.

Key Details

Transaction date: March 27, 2026. Form 4 filed March 31, 2026.
Items reported: 13,430 disposition to issuer; 6,715 disposition (derivative). Total disposed = 20,145.
Price/Value: N/A (no cash price or total dollar amount reported).
Shares owned after transaction: Not specified in the Form 4 provided.
Footnotes: F1 describes the November 6, 2025 arrangement and the court‑approved plan of arrangement completed March 27, 2026; F2 explains the BBHC exchangeable shares were previously exchangeable into BBU units and were exchanged one‑for‑one for the Corporation’s class A subordinated voting shares.
Filing timeliness: Form filed March 31, 2026; the filing does not indicate a late reporting flag on the form as provided.

Context

The derivative line (6,715) reflects BBHC exchangeable shares being exchanged as part of the corporate reorganization, not an options exercise or open‑market sale. This is a structural conversion tied to the Arrangement, so it’s a corporate restructuring event rather than a signal of insider buying or selling intent.
