Meaning
A supplementary financial or operational benefit awarded to select shareholders outside the formal purchase agreement alters uniform distribution among equity holders. Receiving side deal consideration includes consulting contracts or employment retention bonuses paid exclusively to lead founders or major funds during an acquisition. This condition stops applying when all side arrangements are fully disclosed, evaluated for fair value and approved by unconflicted shareholder majorities.
Differential Payout
Acquirers often offer side deal consideration to align founder incentives or secure voting consent from critical equity holders. Additional payments disguised as consulting fees or future performance bonuses divert total deal value away from the main purchase price waterfall. Common shareholders who receive only standard merger consideration suffer financial dilution because total enterprise purchase capital is siphoned into side agreements.
This practice creates severe friction between founding executives receiving retention packages and passive investors holding uncompensated equity.
Fiduciary Breach
Siphoning merger valuation into private side arrangements invites immediate judicial challenge from excluded equity holders. Courts examine whether side deal consideration represents genuine post-closing employment value or hidden merger consideration designed to bypass charter distribution rules. Directors who approve M&A deals containing unequal shareholder benefits lose standard legal immunities if payments reflect unfair diversion of corporate proceeds.
Litigation Risk
Post-closing shareholder lawsuits challenging secret side payments force founders to defend personal compensation contracts in court. Defense costs and potential clawbacks erode executive gains from sale transactions.
