Cap Table Analysis

cap-table-analysis

Cap table modeling — rounds, dilution, option pools, liquidation preferences.

When to Activate

• Building or updating a capitalization table for a startup or private company
• Modeling the impact of a new funding round on existing shareholders
• Calculating dilution from option pool creation or expansion
• Analyzing liquidation preferences and waterfall scenarios
• Evaluating conversion scenarios for convertible instruments (notes, SAFEs)
• Preparing for a liquidity event (M&A, IPO) and computing shareholder proceeds
• Advising founders on the true cost of a proposed term sheet

Core Concepts

Cap Table Construction

A capitalization table records every equity interest in the company — common shares, preferred shares, options, warrants, convertible instruments:

• Fully diluted share count: Includes all issued shares plus all shares issuable upon exercise of options, warrants, and conversion of convertible instruments. This is the denominator for ownership calculations
• As-converted basis: All preferred shares shown as if converted to common. Used for ownership percentage calculations
• Share classes: Common (founder, employee), Preferred (Series Seed, A, B, C — each with its own terms)
• Authorized vs. issued vs. outstanding: Authorized is the maximum; issued includes treasury shares; outstanding excludes treasury
• Ledger format: Each transaction (grant, exercise, transfer, repurchase, conversion) recorded chronologically

Share Class Economics

Each preferred series has distinct economic rights that affect payout at exit:

• Liquidation preference: Dollar amount preferred holders receive before common shareholders. Typically 1x the original investment
• Dividend rights: Cumulative (accrues whether declared or not) or non-cumulative. Participating or non-participating
• Conversion ratio: Initially 1:1 (one preferred share converts to one common share). Adjusted by anti-dilution provisions
• Voting rights: Preferred may vote on an as-converted basis or have specific class votes (protective provisions)
• Redemption rights: Rare in VC but some Series have a put right after 5-7 years

Dilution Math

Dilution is the reduction in ownership percentage when new shares are issued:

Dilution % = New Shares Issued / (Pre-Existing Shares + New Shares Issued)

Pre-round ownership:  Shares Held / Pre-Money Fully Diluted Count
Post-round ownership: Shares Held / Post-Money Fully Diluted Count

• Primary dilution: New shares issued in a funding round
• Option pool dilution: Creating or expanding the ESOP. If done pre-money, existing shareholders (including the new investor in economic terms) bear the dilution
• Anti-dilution dilution: If anti-dilution protection triggers, additional shares are issued to prior investors — diluting common and unprotected shareholders further
• Cumulative dilution across rounds: Multiply retention ratios: (1 - dilutionround1) (1 - dilutionround2) ... = cumulative retention

Option Pool Creation and Shuffling

• Pre-money option pool: The term sheet states the option pool as a percentage of pre-money fully diluted shares. This means existing shareholders create the pool before the new investment, bearing all the dilution
• Post-money option pool: Pool created after the investment — dilution shared proportionally among all shareholders including the new investor. Less common but more founder-friendly
• Pool sizing: Typically 10-20% at Series A. Should cover 18-24 months of hiring. Undersizing requires expansion (more dilution) sooner; oversizing wastes founder equity
• Shuffle: Investors insist the pool is created pre-money, effectively lowering the real pre-money valuation of the operating company

Stated pre-money:          $20M
Option pool (15%):         $3M worth of shares created pre-money
Effective pre-money:       $17M (value attributable to existing shareholders before pool)
Investment:                $5M
Post-money:                $25M
Investor ownership:        $5M / $25M = 20%
Pool:                      15%
Founders + existing:       65% (not 80%)

ESOP (Employee Stock Option Plan)

• Vesting: Typically 4-year vesting with 1-year cliff (25% vests at month 12, remainder monthly)
• Exercise price (strike price): Must be set at fair market value (409A valuation in the US). Determines the option holder's cost basis
• Diluted vs. vested: Cap table should show both — fully diluted (all granted options) and vested only. Unvested options may be forfeited upon departure
• Early exercise: Some plans allow early exercise (before vesting) subject to repurchase right. Creates 83(b) election opportunity for tax planning
• Cashless exercise: At liquidity event, exercise price is netted from proceeds — no out-of-pocket cost for the holder

Liquidation Preferences

Determine how proceeds are distributed in a liquidity event (sale, dissolution, deemed liquidation):

1x Non-Participating Preferred:

• Investor gets back 1x their investment OR converts to common and shares pro rata — whichever is greater
• At low exit values, the preference protects downside. At high exit values, conversion to common yields more
• Conversion threshold: The exit value at which converting to common yields more than the preference. = Liquidation Preference / Ownership %

Participating Preferred:

• Investor gets 1x preference PLUS pro rata share of remaining proceeds as if converted to common
• Double-dips: gets the money back and shares in the upside
• Significantly more investor-favorable than non-participating

Participating with Cap:

• Participating up to a total return cap (e.g., 3x). After the cap, treated as converted to common
• Compromise between non-participating and fully participating

Multiple liquidation preferences:

• 2x or 3x preference: Investor gets 2x or 3x their investment before common shareholders receive anything
• Increasingly rare but appears in later-stage rounds, especially bridge or down rounds

Conversion Scenarios

• Voluntary conversion: Preferred holder converts to common when the pro rata common share exceeds the liquidation preference
• Automatic conversion: Triggers upon IPO (typically at a minimum offering price and size) or upon vote of the preferred class
• Shadow preferred / Series stacking: Each series may convert independently. In a waterfall, Series C gets paid first, then B, then A, then common. Earlier series may be "underwater" — their preference exceeds their pro rata value but conversion also yields less

Pay-to-Play

Compels existing investors to participate in subsequent rounds to maintain their preferential rights:

• Full ratchet conversion: Non-participating investor's preferred converts to common (losing liquidation preference, anti-dilution, and other preferred rights)
• Shadow preferred: Non-participating investor converts to a lesser class of preferred with reduced rights
• Purpose: Prevents free-rider problem where existing investors refuse to participate in a down round while retaining their liquidation preference that subordinates new investors

Methodology

1. Gather all equity instruments: Collect articles of incorporation, stock purchase agreements, option grants, convertible note and SAFE agreements, warrant agreements
2. Build the share ledger: Record every issuance, transfer, exercise, and cancellation chronologically
3. Model each round: For each funding round, compute pre-money shares, new shares issued, post-money cap table, and per-share price
4. Layer in convertibles: Model conversion of notes and SAFEs at the applicable discount, cap, or both — computing the effective price and resulting shares
5. Option pool analysis: Show the pool creation, allocated vs. unallocated, vested vs. unvested
6. Waterfall analysis: Model the distribution of proceeds at various exit values, applying liquidation preferences in priority order
7. Sensitivity table: Show each stakeholder's proceeds at different exit values ($10M, $25M, $50M, $100M, $250M, $500M+)
