How it works in a data room
When signing and closing are separated, the agreement sets out conditions such as regulatory approvals, third-party consents or financing, and a long-stop date for meeting them. The room keeps hosting documents during that gap: approval filings, consent letters and updates on any matters agreed at signing. Both sides track progress against the date, and extensions are recorded as signed amendments in the legal folder. The room often stays open longer than expected for exactly this reason.
Why it matters in a deal
The long-stop date balances certainty against flexibility. Too short, and a slow regulator can kill a good deal; too long, and the seller is tied up while the business changes. It interacts with break fees, material adverse change protections and interim conduct rules. For data room budgets, it also determines how long the room may need to stay open.

Example
A cross-border energy deal signs with a long-stop date nine months out, conditional on foreign investment approval. The regulator asks follow-up questions twice, and approval arrives in month eight. The parties had prepared an extension amendment just in case, but closing happens with three weeks to spare. The energy and infrastructure guide covers regulated deals.
