Closing a Deal Before Year-End: Data Room Prep

Tactics for Speed

  • Pre-clear Phase-1 / Phase-2 disclosure scope with seller's counsel.
  • Use AI redaction for any large document subset.
  • Set tight Q&A SLA targets (24-48 hours).
  • Run vendor due diligence so confirmatory diligence is short.
  • Pre-prepare the closing-binder template.

Frequently Asked Questions

Can a 10-week closing actually work?

Yes for mid-market deals with prepared sellers. The bottleneck is usually antitrust filings rather than diligence.
