Anti-Dilution Ratchet

Last updated

Quick Answer

The specific mechanism used to adjust conversion prices in a down round, with full ratchet and weighted average being the two main types.

What it is

An anti-dilution ratchet is the specific formula used to recalculate the conversion price of preferred stock when new shares are issued at a lower price. Full ratchet adjusts the conversion price to exactly match the new lower price, while broad-based weighted average takes into account the relative size of the new issuance, resulting in a less punitive adjustment for existing common shareholders.

In Practice

The Series A investors had a full ratchet anti-dilution provision, so when the Series B priced at 50% below their original investment, their conversion price dropped to match — effectively doubling their share count at the founders' expense.

Operational context

What good looks like

  • The term is tied to a real workflow, not just a definition.

  • Ownership, timing, and evidence are clear.

  • The reader can tell what decision the concept supports.

  • Related terms point to the next useful explanation.

Why It Matters

The type of anti-dilution ratchet significantly impacts how much pain is shared in a down round. Founders should push for broad-based weighted average, which is more standard and less punitive than full ratchet.

VC Beast Take

Full ratchet provisions are a red flag in term sheets. They signal either an inexperienced founder who didn't negotiate or an aggressive investor. In practice, full ratchet can create a death spiral in down rounds that makes the company nearly impossible to finance.
