Earn-Out Mechanism Disputes
1. Introduction
An earn-out mechanism is a contractual arrangement in mergers and acquisitions (M&A) where the purchase price is partially deferred and contingent on the future performance of the target company.
Disputes often arise over:
Calculation of earn-out amounts
Interpretation of performance targets or milestones
Accounting methods or adjustments
Good faith and conduct of the parties
Enforcement and timing of payments
Earn-out disputes are frequently resolved via arbitration, as parties include arbitration clauses in share purchase agreements (SPAs) or joint venture agreements. Singapore is a preferred jurisdiction for international earn-out disputes, governed by the International Arbitration Act (IAA, Cap. 143A).
2. Key Principles in Earn-Out Disputes
2.1. Interpretation of Clauses
Courts and arbitral tribunals emphasize contractual intent, focusing on plain language and agreed definitions of financial metrics.
2.2. Good Faith and Reasonable Conduct
Parties are expected to act in good faith, not manipulating operations or accounting to avoid earn-out payments.
2.3. Discretion and Tribunal Role
Where agreements give discretion to determine earn-out, tribunals will interpret it objectively, often requiring evidence of standard industry practice.
2.4. Arbitrability
Earn-out disputes are generally arbitrable because they are contractual and civil in nature.
2.5. Interim Relief
Courts may grant injunctions or freezing orders to preserve assets or prevent manipulation during arbitration.
