Liquidation Waterfall
The defined order in which exit or liquidation proceeds are distributed across a company's different classes of stockholders.
The waterfall determines exactly who gets paid, in what order, and how much when a company is sold or liquidated — typically starting with any secured debt, then preferred stockholders' liquidation preferences (often paid in reverse order of seniority, most recent round first), then remaining proceeds to common stockholders, subject to any participation rights along the way.
Modeling the waterfall accurately for a specific deal size is essential for understanding real outcomes for founders and employees, since the headline exit valuation can be very different from what common stockholders actually receive once every preference, participation right, and option strike price is accounted for.
The waterfall is where headline exit valuations become real outcomes. Common holders — founders, employees, option holders — are paid only after every debt claim, preference, and participation right ahead of them, so a respectable-sounding acquisition can leave common with far less than its ownership percentage suggests, or nothing.
Non-participating preferred has a built-in break-even: below a certain exit value, holders take their fixed preference; above it, converting to common pays more. Every new round's preferences raise the exit value common needs to see meaningful proceeds, so model the waterfall at several exit values before signing a new term sheet, not just before a sale.
Options participate only economically and only if they're in the money: holders effectively receive the spread between the deal price and their strike, and underwater options get nothing.
A company raised $8M across two preferred rounds, each 1x non-participating, and those preferred holders own 40% of the company as-converted. In a $25M acquisition, converting gives them 40% of $25M = $10M, more than their $8M preference, so they convert and common holders share the remaining $15M. In a $15M acquisition, converting would give them only $6M, so they take the $8M preference instead and common shares the remaining $7M.
Build a real waterfall model — not just a back-of-envelope estimate — before any acquisition negotiation or even before signing a new round's term sheet, so founders and the board understand exactly how proceeds actually flow at different possible exit valuations.
Do preferred investors always take their liquidation preference over converting to common?
No — they take whichever is larger: the fixed liquidation preference, or what they'd receive by converting to common stock and taking their pro-rata share, which is typically larger only in strong exits well above the total preference stack.
Who gets paid first in a liquidation waterfall?
Debt and other creditors first, then preferred liquidation preferences in the order the charter sets (often later rounds first, or pari passu), then common stockholders. Participation rights and any accrued dividends sit between the preference and the common distribution where they exist.
How does the conversion break-even work?
Divide the preference by the preferred holders' as-converted ownership. In the example above, $8M of 1x non-participating preferences owning 40% breaks even at $8M / 40% = $20M: below that exit value they take the preference, above it converting pays more.
Do employee stock options participate in the waterfall?
Only if they're in the money: option holders effectively receive the spread above their strike price. Underwater options receive nothing.
