1x liquidation preference gives preferred shareholders first claim on exit proceeds up to the amount they invested—before common stockholders (usually founders and employees) receive anything.

How it works

Imagine a company sells for $30 million. Preferred investors collectively invested $20 million with a standard 1x non-participating preference. They first receive their $20 million back. The remaining $10 million flows to common unless investors convert to common to capture a better split—a choice governed by the charter.

If the sale price is only $15 million, preferred takes $15 million (capped at their 1x), and common gets zero. That is the protective floor investors buy with the preference. Participating preferred—where investors take their 1x and share in the remainder—creates a different outcome; always read the full waterfall, not just the headline multiple.

Why it matters

• Founders: A clean 1x non-participating preference is common in U.S. venture deals. Stacked preferences across multiple rounds or participating structures can wipe out common on moderate exits.
• Investors: 1x is baseline downside protection. Without it, a down exit could return pennies on the dollar even when the company sold for real money.
• Operators: Option pools sit in common stock. A heavy preference stack affects whether your vested options are worth anything in a modest acquisition.

Common mistake

Assuming “1x” always means founders keep everything above the invested amount. Multiple rounds each with 1x preferences stack in seniority order—later rounds often get paid before earlier ones, shrinking the common slice faster than founders expect.
