Outside Date

The contractual deadline in an M&A agreement by which closing must occur, after which either party may terminate if conditions remain unsatisfied. Also called a drop-dead date.

What Is an Outside Date?

An outside date — synonymous with drop-dead date, long-stop date, or sunset date — is the contractual deadline in an M&A definitive agreement by which the transaction must close. If the conditions precedent to closing have not been satisfied or waived by the outside date, either party may terminate the agreement and walk away without liability (subject to certain exceptions, such as a party’s own breach causing the delay).

The outside date creates a hard stop on deal execution risk. It forces both parties to pursue regulatory approvals, shareholder votes, and other closing conditions with urgency, and provides a clean exit if the transaction proves impossible to complete within a reasonable timeframe.

Setting the Outside Date

The outside date is calibrated to provide sufficient time for all closing conditions to be satisfied:

ConditionTypical Timeframe
HSR Act review1-2 months (initial); 6-12 months (with second request)
Multi-jurisdiction antitrust3-12 months
Foreign investment review2-6 months
Shareholder vote2-4 months
Industry-specific approvals2-12 months

Typical Outside Dates by Transaction Type

  • Simple domestic deal: 3-6 months
  • Deal with standard antitrust review: 6-9 months
  • Complex cross-border deal: 9-18 months

Key Provisions

Extension Rights

Most agreements include provisions to extend the outside date if regulatory approval is the sole outstanding condition:

  • Automatic extension — the date extends by 3-6 months if all conditions except regulatory approval are met
  • Optional extension — either or both parties can elect to extend by a specified period
  • Maximum extension — an outer limit beyond which no further extensions are permitted

Termination Consequences

When the outside date passes without closing:

  • No break-up fee if neither party is in breach
  • Reverse termination fee if the buyer’s failure (financing, regulatory effort) caused the delay
  • Break-up fee if the target’s breach prevented closing
  • Survival of certain provisions — confidentiality, expense reimbursement, and fee obligations survive termination

Restrictions on Termination

A party may not terminate at the outside date if:

  • Its own material breach of the agreement caused the failure to close
  • It failed to use commercially reasonable (or best) efforts to satisfy conditions within its control
  • It is otherwise acting in bad faith

Strategic Considerations

Ticking Fees

Some agreements include “ticking fees” — daily or monthly payments by the buyer to the seller for each day closing is delayed beyond a specified date. Ticking fees compensate the seller for the cost of operating under interim covenants and the uncertainty caused by a protracted closing process. They also incentivise the buyer to accelerate regulatory approvals.

Hell-or-High-Water Clauses

Buyers may agree to “hell-or-high-water” commitments — obligations to take all actions necessary to obtain regulatory approval, including divesting overlapping businesses. These provisions interact with the outside date by reducing the buyer’s ability to allow regulatory delay to run out the clock.

Relationship to MAC Clause

If a material adverse effect occurs before the outside date, the buyer may terminate under the MAC condition rather than waiting for the outside date. The MAC clause and the outside date provide complementary exit rights: the MAC for deterioration in the target’s business, and the outside date for execution failure.

APAC Context

Australia — outside dates in Australian schemes of arrangement are typically 6-12 months from signing, reflecting the time required for ACCC review, court hearings, and the scheme meeting. The scheme implementation deed specifies the outside date and extension mechanics. FIRB (Foreign Investment Review Board) approval timelines have increased in recent years, sometimes requiring longer outside dates for cross-border transactions.

India — Competition Commission of India review timelines, combined with sector-specific approvals (RBI, SEBI, IRDAI), can require outside dates of 9-15 months for complex transactions. The CCI’s Phase II review process adds significant uncertainty to the timeline.

Hong Kong — outside dates in Hong Kong public M&A are influenced by the Takeovers Code’s timetable requirements. The Code imposes specific deadlines for various steps in the offer process, and the outside date in the underlying agreement must accommodate these regulatory timelines.

“The outside date is the most important calendar date in any M&A agreement after closing,” observes Daniel Bae, founder of Amafi. “In APAC cross-border deals, setting it requires a jurisdiction-by-jurisdiction mapping of every regulatory timeline — underestimate any single approval, and the entire deal is at risk.”
