How Does an Investor Analyse a Cap Table?
A cap table shows who owns a company, but a figure such as 12% leaves several questions open. It may refer only to shares held today or include claims that could become shares later. Voting rights and exit-payment terms explain other parts of the stake that the percentage cannot show.
The legal record shows the shares held today. Options and convertible instruments add another layer because they may become shares later. A proposed funding round changes the picture again as new investors join. Each version describes ownership at a different point, while the rights attached to the shares determine control and exit proceeds.
An investor who treats share count as a measure of control can reach the wrong conclusion. Reddit's public filing shows why. At its June 8, 2026 annual meeting, Class A and Class B shares voted together, but each Class B share carried 10 votes while each Class A share carried 1 vote. Two holders could own the same number of shares and still have very different voting power. This public example illustrates the mechanism; it is not presented as a Frontierspace investment or result.
The Different Questions a Cap Table Answers
The meaning of an ownership stake changes as a company raises money and moves closer to an exit. A cap table helps explain those changes by answering several related questions:
- Who holds each class or instrument, and how many securities are issued and outstanding?
- Which options, warrants, restricted awards, SAFEs, notes and other securities could turn into shares? How would they change the share count used to work out ownership?
- How will new money, conversion mechanics, and an option-pool increase change every holder's stake?
- Which holders can vote, appoint directors, block actions, or exercise protective rights?
- How do debt, liquidation preferences, conversion choices, fees, and carry affect proceeds?
These questions belong together. A fully diluted percentage may be accurate for a financing discussion but still say little about voting control or the order in which exit proceeds will be paid.
Why the Share Count Changes the Percentage
The denominator is the share count beneath the percentage. If that share count changes, the percentage changes even when the investor's number of shares does not.
For a company valued at $40 million before a round, 10 million fully diluted pre-money shares imply a price of $4.00 per share. That price changes if the round's terms add an option-pool increase or converting instruments to the share count before the new money arrives. The same $40 million valuation is then spread across more shares, so each share costs less and existing holders bear more dilution.
Ownership can therefore look different in different versions of the same cap table. The issued-and-outstanding version counts the shares that exist today. A fully diluted version also includes the options and convertible instruments covered by the agreed definition. The financing pro forma takes this a step further by showing how ownership may change when the proposed round closes.
The four views describe shares held today, the fully diluted share count, the proposed funding round and the exit payout. Each explains a different part of ownership. The legal documents and deal terms set the actual result.
Four Views of the Same Capital Structure
No single ownership percentage captures the current record, future dilution, control, and exit proceeds.

How the Legal Records Support the Cap Table
A forecast of future ownership depends on an accurate record of what exists today. Even a polished spreadsheet may contain an old option balance or miss a right agreed in a side letter. It may also use conversion terms that differ from the signed agreement. These gaps can change the forecast, which is why the underlying records matter as much as the spreadsheet.
- Corporate records: The charter and stock ledger describe the shares and their holders. Board and shareholder approvals, along with share certificates where used, support that record.
- Financing documents: The stock purchase, investor-rights, voting and transfer agreements contain the terms agreed with investors.
- Employee equity: The equity plan sets the pool's size and rules. Grant records show what has been promised, when it vests and whether options have been exercised or cancelled. Shares bought back affect the balance too.
- Other instruments: SAFEs, notes, warrants and restricted awards may create future claims on shares. Side letters and terms agreed for a company purchase may add rights that are absent from the main spreadsheet.
The NVCA financing-document set, current on July 25, 2026, is useful because it shows how the pieces fit together. The charter defines the securities, while the stock purchase agreement records the financing. A separate voting agreement can change control. Investor-rights and transfer agreements determine how information and ownership may move. The models reveal the architecture, but the company's signed documents determine the actual answer.
How a Funding Round Changes Ownership
Once the current table reconciles, the proposed financing can be added. The headline valuation gives a useful first estimate, but it is not yet the final ownership answer.
A $10 million investment at a $40 million pre-money valuation appears to buy 20% of a simple $50 million post-money value. The final share count also depends on the option pool and the terms of any instruments that convert. A pool increase before the round adds shares to the pre-money count, as a SAFE conversion can do. These changes affect the price per share used for the new investment. Existing holders may therefore lose more of their stake than the headline 20% suggests.
The pro forma connects the current ownership record to the proposed result through a series of calculations:
- The dated version of the current table provides the starting share count and its source records.
- Each SAFE, note, warrant or other instrument converts under its own terms, which determine how many shares it adds.
- The option-pool calculation separates granted, exercised, cancelled and unallocated shares.
- The agreed price per share and funding terms determine how many new shares the investor receives.
- The resulting table shows each holder's shares, class, fully diluted percentage and voting power.
A consistent model accounts for all shares and totals ownership to 100%. Voting power follows the rights of each class rather than necessarily matching that ownership split. An unexplained gap can point to missing records or a mistaken assumption.
How Dilution Builds Across Rounds
When a new cap table replaces the old one, it can become hard to explain how a holder's stake changed. A record linking the two dates makes that history visible. It shows shares added through funding rounds, pool increases, grants and exercises. Conversions and anti-dilution changes also affect the count, while transfers, buybacks and cancellations explain other movements.
The bridge also prevents a common arithmetic mistake. If a stake is diluted by 20% in one round and by 15% in a later round, it retains 68% of its starting ownership: 80% multiplied by 85%. Adding the two dilution percentages would imply that 65% remains, which is wrong because the second round acts on the already diluted stake.
This shows how dilution builds across rounds. The investor can test how much of its stake may remain after several rounds. It can then decide whether it needs pro rata rights or cash set aside to invest more.
What the Option-Pool Balance Leaves Out
The option pool deserves its own schedule because the headline balance does not reveal how much equity has already been promised. A large pool may be mostly granted, while a smaller one may contain enough unallocated equity for the hiring plan. Those are very different situations.
Carta's Founder Ownership 2026 report, published on March 13, 2026, illustrates the pool's importance. In its Series C dataset, the median employee pool of 16.8% slightly exceeded median founder ownership of 16.1%. The figures provide a market reference, while the company's own hiring plan explains how much equity it may actually use.
That leads to four practical questions:
- How much of the plan is approved, granted, exercised, cancelled, or still unallocated?
- Which holders absorb a proposed pool increase?
- Does the requested pool match a role-by-role equity budget through the next expected financing?
- How do outstanding awards and future grants affect the fully diluted denominator?
An equity budget tied to planned hires gives the pool a clearer basis than a market median. It shows how much equity the company expects to offer for each role. Investors can then see whether a proposed pre-money pool increase matches those needs or asks existing holders to accept more dilution than the hiring plan supports.
Why Ownership and Control Can Differ
The Reddit example shows why control needs a separate explanation from share ownership. Share count describes the stake, while voting classes, board rights and consent terms shape who can influence important decisions.
- Voting classes: Different classes may carry different votes per share or no vote on ordinary matters.
- Board rights: Appointment and observer rights may sit with a class, investor, or ownership threshold.
- Protective provisions: A minority holder may have the right to approve new funding or a sale. It may also have a say on changes to the charter and other major actions.
- Threshold rights: Some rights may end when a stake falls below a set size. This can affect access to reports, pro rata investment, share registration and a say in company decisions.
A minority stake can carry meaningful influence, while a larger share of the economic value can come with little formal control. The cap table and the share rights describe those different parts of ownership.
How Ownership Translates Into Exit Proceeds
The same separation is needed at exit. A holder with 12% of the fully diluted shares does not automatically receive 12% of the proceeds. Debt, liquidation preferences, conversion choices, and vehicle-level fees may all be paid before the investor reaches its net result.
- Senior claims: Debt and deal costs may be paid first. These and other claims with priority can reduce the cash left for shareholders.
- Preference stack: Each preferred series has its own payout terms. Its multiple and payment order set the initial claim. Participation terms govern whether it also shares in the remaining cash, while caps and amounts accrued over time can change the total.
- At some exit values, a preferred holder receives more by converting to common shares than by taking its preference.
- Vehicle layer: An investor holding through an SPV may receive less after the vehicle's expenses, management fees and carry.
At one exit value, a preferred holder may receive more by taking its preference. At another, conversion to common may pay more. Share class, preference, and capital-structure analysis explains how that choice affects the payout.
Cap Table Diligence Questions
- How current is the table, who maintains it and what has changed since the prior version?
- Are all equity classes, awards, warrants, SAFEs, notes, side letters, and transfer commitments included?
- Which securities are included in each ownership percentage, and does that definition match the financing documents?
- Can every issuance, grant, transfer, and cancellation be traced to the required authorization?
- How do ownership, voting power, and proceeds change under the proposed round, a down round, a pool increase, and several exit values?
- Which discrepancies remain open, who is resolving them and could they affect closing or the economics?
Which Cap Table Is the Real One?
The completed review returns to the ownership percentage that first caught the investor's attention. The analyst can now explain which denominator produced it and how the next financing may dilute it. The same analysis shows whether voting rights move with the stake and how the security participates in an exit.
These views belong to the same investment. The legal record explains the shares held now, the funding model shows how they may change, and the rights attached to them shape control and payouts. Consistent definitions let the committee follow a stake through that whole story.
Frequently Asked Questions
What is a fully diluted cap table?
It shows shares held today plus other claims that could become shares, such as options, awards, warrants and convertible securities. The chosen definition sets which claims count. Two fully diluted tables can therefore show different percentages if they include different instruments.
Is a pro forma cap table the same as the legal stock ledger?
The two records serve different purposes. The stock ledger records issued ownership, while a pro forma models what ownership may look like after a proposed transaction. Signed documents, approvals, and completed issuances establish the legal result.
Why can ownership percentage differ from voting power?
Share classes can have different votes per share. Voting agreements, board rights and rights to block certain actions also affect control. A holder's share of the value need not match its share of the votes.
Can a cap table predict investment returns?
A cap table can support scenario analysis, but it cannot predict returns. Company performance and future financings shape the exit value and timing. Security terms and fees then determine the investor's share. The transaction documents establish the investor's legal entitlement.
