Question 1

What is anti-dilution protection?

Accepted Answer

Anti-dilution protection adjusts existing investors' ownership if a company raises money at a lower valuation (down round). Purpose: protects early investors from price drops. Mechanism: investors receive additional shares to compensate for lower price. Result: founders and employees bear more dilution in down rounds. Common: standard term in preferred stock. Types: full ratchet (severe) and weighted average (most common). Important: only triggers in down rounds, not normal dilution from up rounds.

Question 2

What's the difference between full ratchet and weighted average anti-dilution?

Accepted Answer

Full ratchet: conversion price drops to new lower price completely. Most severe for founders. Rare in practice. Example: $1 original price, down round at $0.50. All previous shares repriced to $0.50 (double the shares). Weighted average: adjustment considers size of down round. More common. Two variants: broad-based (includes all shares) or narrow-based (only certain shares). Example: if down round is small, adjustment is small. Formula: considers old price, new price, and shares issued. Narrow-based is more investor-friendly. Broad-based is more founder-friendly.

Question 3

When does anti-dilution get triggered?

Accepted Answer

Trigger: issuing shares at lower price than previous preferred price. Down round scenarios: company raises at lower valuation, market conditions force repricing, company struggling to raise. Not triggered by: normal option grants, normal fundraising at higher prices. Calculation timing: at closing of down round. Result: prior preferred shareholders receive additional shares (conversion ratio adjusts). Waterfall effect: multiple rounds of preferred stock may all adjust, compounding founder dilution. Monitor: model impact of potential down rounds on your ownership.

Question 4

How does anti-dilution impact founders and employees?

Accepted Answer

Impact: Anti-dilution protects investors, founders and employees bear the adjustment. In down round: investors get additional shares, founder/employee percentages drop more than pro-rata. Example: 50% down round with full ratchet could cut founder ownership in half. Employee options: if underwater (strike > current price), anti-dilution makes ownership even smaller. Common shares: no anti-dilution protection for common holders. Planning: understand anti-dilution terms when signing, model worst-case scenarios. Mitigation: raise at sustainable valuations, avoid down rounds through performance.

Question 5

How can founders negotiate anti-dilution terms?

Accepted Answer

Negotiation points: Type: broad-based weighted average is standard and founder-friendlier than narrow-based or full ratchet. Carve-outs: exclude certain issuances (employee options, acquisitions) from triggering anti-dilution. Pay-to-play: require investors to participate in down round to get anti-dilution benefit. Caps: limit maximum adjustment. Reality: institutional investors expect some anti-dilution. Full ratchet is rare and you should push back hard. Broad-based weighted average is market standard. Early stage: angels often don't get anti-dilution (on SAFEs). Priced rounds: harder to avoid entirely.

Question 6

What is pay-to-play and how does it relate to anti-dilution?

Accepted Answer

Pay-to-play: requires investors to invest in down round to maintain preferential rights. Mechanism: investors who don't participate may convert to common stock, losing anti-dilution and other preferred rights. Purpose: prevents free-riding on anti-dilution protection. Encourages investor commitment. Relation: conditions anti-dilution benefit on continued support. Founder benefit: aligns investor incentives, ensures down round participants aren't excessively diluted for non-participating investors. Common: often appears in later-stage documents. Negotiation: founders should push for pay-to-play when anti-dilution is included.

Question 7

How do you model anti-dilution provisions?

Accepted Answer

Modeling steps: 1) Identify current cap table with all preferred series and conversion prices. 2) Model down round scenario (new price, amount raised). 3) Apply weighted average formula to each series. 4) Calculate new conversion ratios. 5) See new fully-diluted ownership. Formula (broad-based weighted average): New price = Old price × (Outstanding shares + New shares at old price) / (Outstanding shares + Actual new shares). Tools: cap table software (Carta) handles this automatically. Spreadsheet modeling requires careful setup. Scenarios: model multiple down round scenarios to understand sensitivity.

Question 8

How did anti-dilution provisions become standard?

Accepted Answer

History: Anti-dilution emerged as venture capital institutionalized. Purpose: protect professional investors making concentrated bets. Evolution: full ratchet was more common early on. Weighted average became standard as more founder-friendly practices emerged. 2000s: NVCA model documents helped standardize terms. Today: broad-based weighted average is default. Full ratchet rare. Context: part of investor protection package including liquidation preferences, protective provisions. Balance: VCs argue it's fair risk management. Founders see it as heads-I-win-tails-you-lose. Market: terms cycle between investor and founder friendly based on market conditions.
