Definition
An extension is a unilateral act by the bidder to push the tender expiration to a later date. Extensions can be voluntary (to give holders more time, accommodate negotiations) or mandatory (when Rule 14e-1 requires a 10-business-day extension after a material change).
Mechanics
- Announced by press release before the prior expiration time
- Filed as an amendment to Schedule TO
- Withdrawal rights remain in effect throughout
Common reasons
- Material change to terms (price increase, condition modification)
- Regulatory clearance not yet received
- Negotiating support from a significant holder
- Awaiting target board action
Pattern
Multi-month deals often see 5–10+ extensions stacked one after another as the bidder works through regulatory review.
