Cap Table
A cap table (capitalization table) lists all shareholders and their ownership percentages. Essential for calculating proceeds distribution in any M&A transaction.
Full Definition
A capitalization table (cap table) is a detailed record of a company's ownership structure — listing every class of equity, each holder's number of shares, and the percentage ownership represented. In M&A, the cap table determines who gets paid, how much, and in what order when deal proceeds are distributed at closing.
What a cap table includes: A complete cap table lists: common shares outstanding (founders, employees, other common holders); preferred stock by series (Series A, B, C, etc.) with each series' liquidation preferences and conversion ratios; outstanding options and warrants (both vested and unvested) with exercise prices; convertible instruments (SAFEs, convertible notes) with their conversion terms; and any other rights or instruments that could dilute existing stockholders. The "fully-diluted" cap table includes all potential shares assuming every instrument converts or exercises, regardless of whether it's currently in-the-money.
Cap tables in M&A due diligence: Buyers review the cap table to understand exactly who they're buying from and who has the right to approve the deal. Key questions: Who are the major shareholders? Do any shareholders have veto rights over a sale? Are there tag-along rights that require all shareholders to participate? Are there anti-dilution provisions that could change the payout waterfall? Are there options underwater in the deal that must be addressed at closing?
The waterfall analysis: The cap table drives the distribution waterfall — the order and amounts in which proceeds are distributed at close. Preferred stockholders receive their liquidation preferences before common stockholders receive anything. Options may be cashed out, cancelled, or converted depending on their exercise prices relative to the deal price. Unvested options may accelerate (single or double trigger) or be cancelled. Modelling the waterfall across different deal prices and structures is essential to understanding who actually benefits from a transaction.
Common cap table problems: Cap tables at smaller, early-stage, or informally-run businesses are often messy: uncertificated shares, unclear vesting schedules, missing assignment agreements, unauthorized share transfers, equity promised in email but never formally documented. Cleaning up a cap table before going to market — using a cap table management platform and proper legal documentation — accelerates due diligence and builds buyer confidence.
Seller vs. Buyer Perspective
Know your cap table cold before you talk to any buyer. Who owns what percentage? What are the liquidation preferences on preferred stock? What happens to options and warrants at various deal prices? Run the waterfall at your target price before any conversation with a buyer — you need to know exactly what you'll net, not the gross deal price. Founders in venture-backed companies often discover in the waterfall analysis that preferred investor preferences consume far more of the proceeds than expected.
Request a fully-diluted cap table on day one of diligence. Verify it against the company's stock ledger, board resolutions authorizing share issuances, and any convertible instrument agreements. Discrepancies between the cap table and supporting documents are a significant red flag — either the cap table is wrong (messy record-keeping) or someone is hiding equity interests. The cap table also determines who must sign the deal documents — if someone holds 5% and their signature is required for the deal to close, you need to know that before you start negotiating.
Real-World Example
A venture-backed software company is acquired for $8M. The cap table shows founders with 40% common, Series A investors with 30% preferred ($3M liquidation preference), Series B investors with 20% preferred ($4M liquidation preference), and employees with 10% common (options). The waterfall: Series B gets their $4M first; Series A gets $3M next; $1M remains for common holders. The $1M split 80/20 between founders (40% common) and option holders (10% common) after adjusting for outstanding option shares. Founders net $800K on an $8M deal — not the $3.2M a naive 40% calculation would suggest.
Why It Matters & Common Pitfalls
- !'Fully diluted' means something specific. Make sure the cap table you're reviewing includes all potential dilutive instruments, not just currently-outstanding shares. Options, warrants, convertible notes, and SAFEs all belong in the fully-diluted count — and missing any of them changes the per-share deal price.
- !Liquidation preferences can flip the economics dramatically. In down-round or modest-exit scenarios, preferred liquidation preferences may consume nearly all proceeds, leaving common stockholders with minimal payouts. Model multiple exit price scenarios — particularly prices below and near the invested capital — to understand each class's incentives.
- !Option plan mechanics need careful attention. Board approval of the option plan, individual grant documentation, proper exercise prices (409A compliance), and vesting schedules must all be verified. Defective option grants create legal liability and complicated closing mechanics.
- !Shareholder approval requirements can delay or block deals. Some transactions require approval from a specified percentage of shareholders — or from specific classes of preferred stockholders. Identify blocking positions early: a single investor with 5% ownership but class-voting rights can hold up or prevent a deal.
