The practice of 'revesting'—making a founder's deal proceeds contingent on continued employment—is becoming more aggressive. With talent-only deals, some acquirers argue for revesting 100% of the founder's payout, asserting that the payment is for future work, not for the now-irrelevant business they built.

When their board pushed for an acquisition with egregious terms, the founders realized their required three-year employment contracts were their ultimate leverage. By refusing to sign, they could effectively veto a deal that the board otherwise had the votes to pass.

Serial acquirer Lifco improves post-acquisition performance by having sellers retain an ownership stake in their business. This goes beyond typical earn-outs, keeping the founder's expertise and incentives aligned with the parent company for long-term growth, rather than just hitting short-term targets.

An earn-out is a tool for alignment, not just a financial hedge. If a target company is on track to miss its earn-out targets, a savvy acquirer will proactively renegotiate the terms. The long-term value of retaining and motivating the key team members outweighs the short-term financial gain of a missed payment.

Many founders honestly commit to staying after an acquisition but underestimate the psychological shift from owner to employee. The loss of ultimate control often leads to their departure, despite their best intentions and contractual obligations. Diligence must assess this psychological readiness.

Understanding a founder's real motivation for selling is crucial. Some want a partner for growth, while others are seeking an exit. A founder could take a partial earn-out and leave the day after closing, abandoning the business and becoming your biggest integration risk.

A buyer can mitigate the risk of losing critical talent by making a deal's closure contingent on securing the commitment of a few essential employees. This shifts the responsibility to the seller to ensure those key individuals are motivated and aligned with the acquisition.

Go beyond standard performance-based earn-outs by structuring payments with 'kickers' that reward sellers for specific de-risking actions. For example, if there's high customer concentration, offer an additional payment for diversifying revenue away from the main client, aligning them with the buyer's risk mitigation goals.

Palo Alto Networks' M&A strategy requires founders to "unvest" half their existing stock. This is offset by a generous new equity grant (25-40% top-off) in the parent company, creating powerful financial incentives for founders to stay for the new three-year vesting period.
