Purchase Price Adjustment
A purchase price adjustment is a contractual mechanism that changes the amount ultimately paid in an acquisition based on specified closing-date items or calculations.
Why the term matters
Purchase agreements often start with a base or enterprise value and then adjust for items such as cash, indebtedness, transaction expenses and net working capital. The agreement typically defines an estimated closing statement, a post-closing calculation process, review rights, dispute procedures and a final settlement. The precise formula is transaction-specific.
The adjustment bridges headline value and closing value
A buyer may agree to an enterprise value before the exact closing balance sheet is known. The purchase-price formula converts that headline value into the amount payable for the actual business delivered at closing.
This helps prevent either side from receiving an unintended benefit from short-term changes in cash, debt or working capital.
Estimated numbers are often trued up later
A common structure uses an estimated closing statement shortly before closing and a buyer-prepared post-closing statement after the books can be finalized. The seller receives review rights and may dispute specified calculations.
Recent 2026 SEC-filed acquisition agreements use this estimated-versus-final approach for cash, debt, transaction expenses and working capital.
Double counting is a major drafting risk
A liability should not normally reduce price twice—once as debt and again inside working capital—unless the contract intentionally says so. Purchase agreements therefore often include detailed accounting principles and rules designed to prevent duplication.
The adjustment model should be tested with actual balance-sheet line items before signing.
The adjustment is not necessarily a renegotiation
When the formula works as intended, a post-closing adjustment applies rules the parties already negotiated. It is different from reopening valuation because one party later dislikes the economics.
Disputes usually focus on definitions, accounting consistency or factual amounts rather than the original headline multiple.
Common mistakes
Treating enterprise value as the final check to sellers Cash, debt and other agreed items can materially change equity proceeds.
Leaving accounting rules vague Different classifications can shift value even when the underlying business has not changed.
Forgetting dispute mechanics Deadlines, access rights and the neutral accountant process can determine how efficiently a true-up is resolved.
Example
A deal has a $100 million base value. At closing, the agreement adds $4 million of cash, subtracts $18 million of debt and subtracts a $2 million working-capital shortfall. Ignoring other items, the resulting equity consideration is $84 million. A later post-closing true-up may change that amount if final figures differ from the estimates.

Professional note
The economics live in the definitions. “Cash,” “indebtedness,” “transaction expenses” and “working capital” can each contain negotiated inclusions and exclusions. A seemingly minor definition can move value dollar-for-dollar.
