# What Is Down-Round Protection?

> Down-round protection refers to contractual terms—chiefly anti-dilution provisions—that shield preferred investors from full dilution when a company raises at a lower valuation.

**Down-round protection** is the bundle of legal rights that reduce how much preferred investors dilute when a company raises at a lower price than their original investment.

## How it works

The main tool is **anti-dilution** in the certificate of incorporation. Two common flavors:

**Weighted average anti-dilution** adjusts the conversion price based on how much money was raised down and how far the price dropped. It is the market standard in most U.S. venture deals.

**Full ratchet** resets the earlier investor's price to the new lower price as if they had invested at the down round—much harsher on founders and common.

Example: an investor bought Series A at $1.00 per share with broad-based weighted average protection. A Series B down round at $0.60 triggers a conversion price adjustment. The Series A holder receives additional shares on conversion without paying new money—ownership shifts away from common.

Other protections include **ratchets** tied to milestones, **liquidation preference** multiples that step up on down rounds, and **pay-to-play** that suspends protection for non-participating investors.

## Why it matters

- **Founders:** Down-round protection can silently transfer 5–15+ points of ownership in bad scenarios. Model cap tables with down-round cases before signing.
- **Investors:** Protection aligns incentives—earlier backers took risk and want guardrails. New investors may resist excessive ratchets that block clean financings.
- **Employees:** Common and option pools bear most anti-dilution pain. Repricing may be needed to retain talent after a reset.

## Common mistake

Assuming "standard" anti-dilution is harmless. Weighted average is normal, but narrow-based formulas and full ratchets still hurt. Read the exact formula in the charter, not the term sheet summary.

## FAQ

### What is Down-Round Protection in simple terms?

Legal language in preferred stock that gives earlier investors extra shares (or a lower effective price) if a later round prices below theirs. It limits how much their ownership gets diluted.

### Why does Down-Round Protection matter?

In a down round, protected investors gain shares at founders' and common holders' expense. Founders should model scenarios before signing broad anti-dilution terms.
