Risks & Post-Merger Integration

A complete IB workup names every binding risk and pre-funds a mitigant. The MSFT × ATVI deal's defining feature was its 21-month regulatory journey — uncommon, instructive, and a template for future cross-border mega-deals.

Deal Outcome

Deal closed October 13, 2023 — 21 months after announcement.
