Mackenzie Donald William 4

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.

• 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.

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.
