A capitalization table, or cap table, is the record of who owns a company: every share of common and preferred stock, every option and warrant, and every SAFE or convertible note that may turn into stock. For a startup, an accurate cap table is essential because investors and acquirers rely on it in due diligence, and errors can delay a financing, reduce sale proceeds or trigger disputes. The cap table must also match the company’s legal records, which is where many problems start.
Many founders keep their first cap table in a spreadsheet and update it only when an investor asks. That approach tends to break down quickly. Here is what a cap table should include, how pro forma tables work, and the legal issues that most often surface in diligence.
What Is a Cap Table?
A cap table is a ledger of a company’s equity and equity-linked securities. It shows each holder, the type of security held, the number of shares, and each holder’s percentage ownership. There is no single required format, but a useful cap table generally tracks:
- Issued and outstanding shares of common stock and each series of preferred stock.
- Equity incentive awards: options granted (with exercise price, vesting schedule and grant date), restricted stock and restricted stock units.
- The unallocated option pool reserved under the equity plan.
- Warrants issued to lenders, landlords or service providers.
- Convertible instruments such as SAFEs and convertible notes, with their caps, discounts and other conversion terms.
- Vesting and repurchase rights on founder and employee restricted stock.
Outstanding vs. Fully Diluted Ownership
Ownership can be measured in different ways, and confusion between them causes real disagreements. “Outstanding” ownership counts only shares actually issued. “Fully diluted” ownership generally counts outstanding shares plus all options, warrants and the reserved pool, as if everything were exercised or converted. Financing documents usually define exactly what “fully diluted” includes, and whether SAFEs and notes are counted matters a great deal when pricing a round. Founders should know which measure an investor or employee offer letter is using.
Pro Forma Cap Tables in a Financing
When a company raises a priced round, the parties build a pro forma cap table that shows ownership immediately after closing. It models:
- The new preferred shares issued to investors at the negotiated price.
- Conversion of outstanding SAFEs and notes, which depends on their specific terms. Our article on convertible notes and SAFEs explains these mechanics.
- Any increase in the option pool, which investors often require to be counted before the new money comes in.
The pro forma table drives the price per share and each holder’s dilution, so small errors can shift real value. It is also used to confirm that the restated charter authorizes enough shares. See our overview of Series A financing for how these pieces fit together.
The Cap Table Must Match the Legal Records
A cap table is only a summary. The legal source of truth is the company’s corporate records: the charter, board and stockholder approvals, stock purchase agreements, option grant documents, the stock ledger and any stock certificates or notices for uncertificated shares. In diligence, investors’ counsel will compare the cap table line by line against these records. Common problems include:
- Equity promised but never properly issued, such as shares or options mentioned in an offer letter or email without board approval.
- Founder stock issued without documentation, or without an IP assignment to the company.
- Missing 83(b) elections for restricted stock subject to vesting, which can create significant tax problems for the holder. See the benefits of making an 83(b) election.
- Options granted without a supportable exercise price, meaning without a current Section 409A valuation, which can create adverse tax consequences for employees.
- Issuing more shares than the charter authorizes, or more options than the plan reserves.
- Securities law gaps, such as stock or options issued without a valid exemption. Employee equity in California often relies on federal Rule 701 and California Corporations Code Section 25102(o), which carry their own conditions and notice requirements.
Some defects can be fixed after the fact. Delaware, for example, has statutory procedures for ratifying defective corporate acts and stock issuances. Corrections are generally simpler and less expensive when they are found early rather than in the middle of a financing or acquisition.
Why the Cap Table Matters in an Exit
In an acquisition, the cap table becomes the basis for the “waterfall” that determines how sale proceeds are divided. Liquidation preferences, participation rights, option treatment and escrow or holdback allocations all depend on accurate data. Buyers typically require stockholders and the company to stand behind the cap table through representations and indemnities, so mistakes discovered after closing can become claims.
Practical Tips for Maintaining a Cap Table
A few habits go a long way:
- Update it with every equity event: each issuance, grant, exercise, transfer, repurchase, cancellation and conversion.
- Tie every entry to an approval and a signed document, and keep those documents organized in a data room.
- Use cap table management software once the company has more than a handful of holders, and reconcile it periodically against the legal records.
- Track vesting and post-termination exercise periods so expired options are removed and departing employees receive accurate information.
- Model before you sign. Run a pro forma before issuing new SAFEs, granting a large option, or accepting a term sheet.
- Remember tax and filing uses. Cap table data supports 409A valuations, qualified small business stock records, and, for Delaware corporations, the franchise tax calculation.
The Takeaway
A cap table is more than a spreadsheet; it is a summary of legal rights that investors, acquirers and employees will rely on. Keeping it current and consistent with board approvals and signed documents from day one is far easier than reconstructing years of equity history under deal pressure.
Frequently Asked Questions
What should a startup cap table include?
It should list every holder of common and preferred stock, all granted options and restricted stock units, the unallocated option pool, warrants, and SAFEs and convertible notes with their conversion terms. Vesting, exercise prices and grant dates should also be tracked.
What is a pro forma cap table?
A pro forma cap table shows ownership as it will look after a proposed transaction closes, such as a priced financing. It models new investor shares, conversion of SAFEs and notes, and any option pool increase so the parties can agree on price and dilution.
What does fully diluted mean on a cap table?
Fully diluted ownership generally counts outstanding shares plus shares issuable on exercise or conversion of options, warrants and the reserved option pool. Deal documents define the term precisely, including whether SAFEs and notes are counted.
Can errors in a cap table be fixed?
Often, yes. Missing approvals can sometimes be ratified, and Delaware has statutory procedures for validating defective stock issuances. Fixes are usually easier and less costly before a financing or acquisition is underway.
