Earnout

An earnout is a contractual provision in an M&A transaction where a portion of the purchase price is deferred and paid to the seller only if the acquired company meets specific performance targets after the deal closes. Earnouts are one of the most common — and most contentious — deal structures in startup acquisitions.

**How Earnouts Work**

In a typical earnout structure, the buyer and seller agree on a total purchase price but disagree on what the company is worth today versus what it could be worth if growth continues. The earnout bridges that gap:

- **Upfront payment:** A baseline amount paid at closing, reflecting what the buyer is confident the business is worth today. - **Earnout payment:** An additional amount (or amounts) paid over 1-3 years if the company hits defined milestones.

Example: A startup is acquired for a headline price of $50M. The buyer pays $30M at closing and structures a $20M earnout tied to the company achieving $15M ARR within 24 months of closing. If the company hits $15M ARR, the founders receive the additional $20M. If they don't, they don't.

**Common Earnout Metrics**

Earnout targets typically fall into three categories:

- **Revenue-based:** Annual Recurring Revenue (ARR), total revenue, or revenue growth rates. Most common in SaaS acquisitions. - **Customer-based:** Customer retention rates, net new customers, or renewal of key contracts. - **Product-based:** Delivery of specific product features, completion of a technology migration, or achieving a regulatory milestone.

**Why Buyers Use Earnouts**

Earnouts protect buyers from overpaying for a company whose future performance is uncertain. If a startup's pitch depends heavily on a product not yet launched, a market not yet entered, or a sales pipeline not yet closed, a buyer may be skeptical of the full valuation. An earnout lets the buyer say: "We'll pay for that upside if and when it materializes."

**Why Sellers Accept (and Resist) Earnouts**

Sellers accept earnouts when they believe strongly in their own projections and want to maximize total deal value — and when the alternative is a lower upfront price or no deal at all. But experienced founders know earnouts carry significant risk:

- **Loss of control:** After an acquisition closes, the buyer controls the business. They may change strategy, redirect resources, deprioritize products, or restructure the team in ways that make hitting earnout targets harder or impossible. - **Accounting manipulation risk:** Buyers can sometimes — intentionally or not — structure intercompany charges, cost allocations, or revenue recognition policies that disadvantage earnout calculations. - **Incentive misalignment:** Founders focused on hitting a 2-year ARR target may make short-term decisions that hurt the business long-term — or may feel trapped in a role they'd otherwise leave.

**Common Earnout Pitfalls**

1. **Poorly defined metrics:** Ambiguous revenue definitions (GAAP vs. non-GAAP, gross vs. net) create disputes. Founders should insist on explicit, auditable definitions in the acquisition agreement. 2. **No acceleration clause:** If the buyer sells the business before the earnout period ends, founders should have provisions ensuring they receive credit for progress or acceleration of remaining payments. 3. **No resource guarantees:** Without contractual commitments to maintain budget, headcount, or product direction, buyers can effectively kill an earnout by starving the business of resources. 4. **Targets set at close-to-impossible levels:** Some buyers use earnouts as a negotiating tool with no real intent of paying them, setting targets just out of reach.

**When VCs Care About Earnouts**

For VC-backed companies, earnouts are most common in acqui-hires and smaller M&A deals where the acquirer is paying a premium for talent and technology but is uncertain about revenue sustainability. In larger, cleaner exits — where the business has proven, recurring revenue and strong retention — buyers have less need for earnout protection and founders have more leverage to negotiate a clean cash-at-close structure.
