China M&A Disputes: Earn-Outs, Representation and Warranty Claims, and Purchase Price Adjustments

Introduction

A China M&A transaction does not end at closing; it ends when the price mechanics have finished running. Earn-outs are missed, warranties turn out to be false, and the purchase price adjustment never settles — and each of those fights lands in front of a Chinese court or tribunal that will read the contract first and the parties' intent second. For a foreign buyer, the single most useful thing to understand is how Chinese law and practice treat the three post-closing battlegrounds, because that is what decides which clauses are worth the paper they are written on.

Valuation Adjustment Mechanisms and the 2019 Minutes

The best-known Chinese price mechanism is the valuation adjustment mechanism (VAM), commonly called a 对赌 ("bet-on" or performance-guarantee) arrangement. Its enforceability was settled in principle by the Minutes of the National Court Work Conference on Civil and Commercial Trial Work (全国法院民商事审判工作会议纪要, issued as 法〔2019〕254号 on 8 November 2019). Article 5 of the Minutes draws the key line:

• A VAM between an investor and the target company's shareholders or actual controller is generally valid, absent other grounds for invalidity.
• A VAM between an investor and the target company itself is not invalid merely because the company is a party — but a claim that the company must repurchase shares or pay cash compensation must also comply with the Company Law rules on capital reduction and profit distribution. In practice, if the company has not completed a lawful capital reduction, a repurchase claim may fail; if it has no distributable profits, a cash-compensation claim may not be enforced.

The practical lesson for a foreign buyer is structural: a performance guarantee signed by the shareholders or the controller is the enforceable form, while a guarantee that runs against the company's own assets carries a built-in capital-rules limitation. Drafting the counterparty correctly is worth more than drafting the formula correctly.

Earn-Outs and Purchase Price Adjustments

Earn-outs and purchase price adjustments are creatures of the contract, and Chinese courts enforce them as such. What breaks them in practice is not the law but the drafting: a metric that can be measured more than one way (net profit, EBITDA, revenue, working capital), an accounting standard that is not pinned down, and a dispute mechanism that never specifies how a disagreement is resolved. The safer structure states the metric, the accounting basis, the measurement date, and a fallback — an agreed accountant or expert, or arbitration — because a price clause without a dispute clause simply converts the earn-out into litigation.

Representation and Warranty Claims

Representation and warranty claims turn on four drafting decisions that Chinese courts will respect if they are written down: the survival period, the notice procedure, the basket and cap, and the remedy (indemnity, price reduction, or both). A buyer that fails to give notice within the agreed window, or that never agreed a window at all, faces a seller's argument that the claim is time-barred or waived. The evidence discipline matters equally: the claim is only as strong as the documents showing what was warranted, what was disclosed, and what turned out to be false.

Practical Points for a Foreign Buyer

• Make the counterparty enforceable. Put performance guarantees against shareholders or the controller, and treat company-backed buybacks as subject to capital-reduction rules under the 2019 Minutes.
• Pin down the price mechanics. Specify the metric, accounting basis, measurement date and a binding dispute route for earn-outs and adjustments.
• Draft the warranty machinery. Survival, notice, basket, cap and remedy — all four, in writing.
• Choose the forum deliberately. Chinese-law M&A disputes are frequently arbitrated; confirm the clause before the dispute exists. For the enforcement backdrop, see Enforcing Foreign Arbitral Awards in China: A Practical Guide.
• Preserve the file. Disclosure schedules, board minutes and the correspondence around closing are the evidence a post-closing claim will stand on.
