Episode notes
Australia's Mandatory Merger Regime Now In Force
- Australia's mandatory suspensory merger regime began 1 January with initial voluntary phase last year.
- Changes include new exemptions, serial acquisition tweaks, and upcoming April rules expanding 'control' triggers to >20% and ≥50% thresholds.
SAMR Treats Mergers As Industrial Policy
- SAMR uses merger control as an industrial policy tool, not just a competition regulator.
- Synopsys‑Ansys shows China may call in sub‑threshold deals in sensitive tech and tie clearance to geopolitical shifts like US export relaxations.
Voluntary Notification Can Protect Timing And Narrative
- Do consider voluntary filings in China even if your deal falls below monetary thresholds.
- Waiting risks SAMR calling the deal in months later and starting the review clock on their terms, losing control of timing and narrative.
