Anti-Sandbagging Clauses in 2026: The Contract Provision Many Buyers Do Not Realize They May Be Giving Up
A Recent Delaware Decision Is Pushing Deal Lawyers to Revisit Buyer Knowledge, Indemnity Rights, and M&A Drafting Strategy
For years, anti-sandbagging provisions were often treated as one of many indemnification-related clauses buried deep inside acquisition agreements.
Today, that is changing.
Following recent Delaware court discussions regarding sandbagging and post-closing indemnification claims, many transactional lawyers are taking a closer look at how purchase agreements allocate risk when a buyer learns about a potential issue before closing.
The issue is attracting significant attention because it sits at the intersection of:
Representation and warranties
Indemnification rights
Buyer knowledge
Due diligence
Disclosure schedules
Risk allocation
Mergers and acquisitions (M&A)
Private equity transactions
Purchase agreement drafting
For deal lawyers, buyers, sellers, private equity sponsors, and M&A advisors, the discussion is becoming increasingly important in 2026.
What Is Sandbagging in M&A?
In private M&A transactions, "sandbagging" generally refers to a situation where a buyer brings a post-closing indemnification claim based on a breach of a representation or warranty even though the buyer may have learned about the issue before closing.
The concept has been debated for years across different jurisdictions.
Supporters often argue that:
The seller agreed to the representation
The purchase agreement allocated the risk
The buyer negotiated contractual protections
Critics often argue that:
A buyer should not benefit from issues it already knew about
The approach may create disputes regarding disclosure and reliance
Transaction expectations may differ between parties
Because of these competing views, sandbagging provisions have become an important drafting issue in many acquisition agreements.

What Is an Anti-Sandbagging Clause?
An anti-sandbagging clause is a contractual provision that may limit a buyer's ability to pursue certain indemnification claims if the buyer knew about the issue before closing.
While drafting approaches vary, these provisions are generally designed to address situations involving buyer knowledge of potential breaches.
In simple terms:
A pro-sandbagging clause generally favors the buyer.
An anti-sandbagging clause generally favors the seller.
Some agreements remain silent on the issue entirely.
The exact impact depends on the language of the agreement, governing law, and transaction-specific facts.
Why Delaware Is Being Closely Watched
Delaware remains one of the most influential jurisdictions for corporate transactions.
Because many acquisition agreements use Delaware law, developments from Delaware courts often receive significant attention from transactional lawyers across the United States.
Recent Delaware decisions have renewed discussion around an important question:
What happens when an acquisition agreement does not expressly address sandbagging?
Historically, practitioners have debated whether Delaware's default approach should favor buyers, sellers, or neither side when agreements remain silent.
That debate has become more active following recent Delaware Chancery Court commentary.
The Delaware Development That Is Driving Discussion
A recent Delaware Court of Chancery decision, In re Dura Medic Holdings, Inc. Consolidated Litigation, has become one of the most discussed M&A cases among deal lawyers.
Commentators have noted that the decision provides additional guidance regarding Delaware's treatment of sandbagging issues.
Several legal analyses have observed that the court discussed Delaware as generally following a pro-sandbagging approach when agreements do not contain an express anti-sandbagging provision.
Legal commentators have also noted the court's emphasis on contractual language and risk allocation within the acquisition agreement itself.
Importantly, lawyers continue to analyze the decision carefully, and transaction outcomes will always depend on specific facts, governing law, and contract language.

Why Buyers Are Paying Closer Attention
Many buyers spend substantial time and resources conducting due diligence before closing.
This often includes reviews involving:
Financial statements
Tax matters
Commercial contracts
Employment issues
Intellectual property
Compliance risks
Litigation matters
The question that frequently arises is:
If diligence reveals a concern, does the buyer lose future indemnification rights?
The answer may depend on:
The purchase agreement
The governing law
Disclosure schedule language
Knowledge qualifiers
Integration clauses
Negotiated sandbagging provisions
For this reason, buyers are increasingly reviewing these provisions earlier in the transaction process.
Why Sellers Are Focusing on Anti-Sandbagging Language
From the seller perspective, the concern is often different.
Many sellers want greater certainty regarding post-closing exposure.
Sellers may argue that if a buyer learns about a specific issue before closing and proceeds with the transaction anyway, the buyer should not later pursue a claim based on the same issue.
As a result, some sellers negotiate for:
Express anti-sandbagging clauses
Knowledge qualifiers
Updated disclosure schedules
More detailed indemnification limitations
These provisions are often heavily negotiated in private company acquisitions.
Why Contract Drafting Matters More Than Ever
One of the biggest takeaways from recent discussions is the importance of precise drafting.
Deal lawyers increasingly focus on:
Knowledge Definitions
What qualifies as buyer knowledge?
Does it mean:
Actual knowledge?
Constructive knowledge?
Knowledge obtained through diligence?
Knowledge of specific individuals?
Different definitions can produce different outcomes.
Disclosure Mechanics
Lawyers are paying closer attention to:
Disclosure schedules
Supplemental disclosures
Document production processes
Data room disclosures
Written notice requirements
These details can become important during post-closing disputes.
Integration Clauses
Recent commentary has highlighted the role of integration clauses.
Some practitioners view integration language as particularly important when determining whether information outside transaction documents affects contractual rights.
How Private Equity Firms Are Responding
Private equity firms frequently participate in transactions where indemnification frameworks receive significant attention.
Many sponsors now review:
Sandbagging provisions
Anti-sandbagging language
Disclosure procedures
Indemnity caps
Escrow structures
Representation and Warranty Insurance (RWI)
earlier than before.
As competition for deals continues, transaction teams often seek greater clarity around risk allocation before signing.
Common Questions Lawyers Are Discussing in 2026
Should Agreements Be Silent?
Some agreements remain silent on sandbagging issues.
Others contain explicit provisions.
The appropriate approach often depends on negotiating leverage, transaction objectives, and risk tolerance.
Does Buyer Knowledge Always Matter?
Not necessarily.
Different jurisdictions may approach the issue differently.
Transaction-specific language can also significantly affect outcomes.
Can Disclosure Alone Resolve the Issue?
Not always.
Lawyers frequently evaluate:
How disclosures were made
Whether disclosures were specific
Whether disclosures appeared in transaction documents
Whether disclosure schedules were updated
Practical Takeaways for Deal Lawyers
Several practical themes continue to emerge from current market discussions:
Buyers
Review sandbagging provisions early.
Understand knowledge-related definitions.
Evaluate disclosure procedures carefully.
Coordinate diligence findings with transaction counsel.
Sellers
Review indemnification provisions closely.
Consider whether anti-sandbagging language is appropriate.
Ensure disclosure schedules are carefully prepared.

Why This Topic Will Continue To Matter
The increasing focus on anti-sandbagging provisions reflects a broader trend in modern M&A transactions.
Parties are paying closer attention to:
Contract interpretation
Risk allocation
Due diligence findings
Buyer knowledge
Seller disclosures
Post-closing indemnification rights
As transaction structures become more sophisticated, lawyers continue to seek greater clarity regarding how representations, warranties, disclosures, and indemnification provisions interact.
For many deal professionals, anti-sandbagging language is no longer viewed as a minor boilerplate provision.
Instead, it is becoming a central part of negotiation strategy in many private M&A transactions.
