Earnout Disputes Surge 40%: Lessons in Contingent Consideration Structuring
bIAnk AI Research · February 2026 · 6 min
Earnout-related litigation has surged 40% in two years, driven by pandemic-era deals with unrealistic milestones. New structuring approaches are emerging to bridge valuation gaps more effectively.
Earnout disputes have surged 40% over the past two years, with courts and arbitration panels increasingly handling disagreements about milestone achievement, accounting definitions, and buyer conduct during the earnout period.
The root cause traces to 2020-2021 vintage deals. Deals done at peak valuations frequently included earnout components to bridge buyer-seller valuation gaps. As post-acquisition performance has fallen short of optimistic projections, disputes have multiplied.
Common flashpoints include ambiguous revenue definitions, buyer interference with earnout achievement (through cost cuts or strategic changes), and disagreements about adjustments for extraordinary items or one-time charges.
Leading practitioners are developing more robust earnout structures. Best practices now include: defining precise financial metrics with worked examples, appointing independent accountants for dispute resolution, and including "commercially reasonable efforts" covenants with teeth.
Alternative contingent consideration structures are gaining traction. CVRs (Contingent Value Rights), synthetic earnouts using escrow mechanisms, and milestone-based deferred consideration with independent verification are all seeing increased adoption.
