Cap Table Hygiene: How Messy Equity Structures Kill Deals

Why Cap Table Problems Kill Deals

Cap table problems are among the most common reasons deals slow down or collapse in early-stage venture financing. The pattern is consistent: a founder reaches a term sheet stage, due diligence begins, and the investor's legal team discovers that the cap table does not accurately reflect the company's actual equity structure. An option pool is larger than shown. A departed co-founder holds shares without a vesting agreement. An early SEIS investor holds convertible notes that were never formally converted. Each problem requires resolution before the transaction can close.

Some of these issues are relatively minor and can be resolved in a few days. Others, particularly those involving departed shareholders who cannot be located or informal equity promises that were never documented, can take weeks to resolve and can involve legal costs that materially change the economics of an early-stage deal. In the worst cases, where the problem cannot be resolved within the investor's timeline, deals fall through entirely.

This article covers what a clean cap table looks like, the most common problems and how they arise, how to clean up a messy cap table before a fundraise, and what investors look for in cap table due diligence. It includes a worked example of a cap table showing fully diluted ownership across share classes.

What a Clean Cap Table Looks Like

A clean cap table has the following characteristics, all of which should be verifiable from company documents held at Companies House and in the company's own records:

• All share classes are documented. Every class of share (ordinary shares, preference shares, A shares, B shares) has a formal Articles of Association provision defining the rights attached to it. There are no undocumented share classes.
• The option pool is accurately accounted for. The total authorised option pool is disclosed. Options that have been granted, including to departed employees who have not yet exercised or forfeited, are listed on a schedule. The distinction between granted-and-unvested, granted-and-vested, and exercised options is clear.
• All shareholder agreements are in place. Every shareholder holds their shares under a documented agreement. Founder shares have vesting agreements. Investor shares have the investment documentation (whether a subscription agreement, a SEIS advance assurance letter, or a convertible note agreement).
• All convertibles are documented and their conversion mechanics are clear. Any SAFE notes, convertible notes, or advance subscription agreements are on a formal schedule showing the amount, the conversion terms, and the current status.
• The register of members at Companies House matches the internal cap table. This should be an obvious requirement but is frequently not the case in early-stage companies, where share transfers and new issuances are sometimes recorded internally but not filed with Companies House.

Common Cap Table Problems

The problems that appear most frequently in pre-fundraise due diligence are:

Missing Vesting Agreements

Founder shares issued at incorporation are frequently not subject to formal vesting agreements, particularly in companies incorporated in the first year or two of operation before founders understood the importance of this. A founder holding fully vested shares from day one, with no vesting restriction, creates a significant problem if that founder leaves the company early. The investor is then funding a business where a departed founder holds a material unconditional equity stake with no ongoing obligation to the company. Most institutional investors will require a vesting arrangement to be put in place retrospectively before proceeding.

Unforfeited Options from Departed Employees

Many early-stage companies grant options to employees without maintaining a disciplined process for tracking option status when those employees leave. Options that should have been forfeited on departure (because they were unvested, or because the employee left and did not exercise) remain on the option schedule as apparently live grants. This inflates the fully diluted share count and the option pool apparently in use.

Informal Equity Promises

Informal promises of equity, made verbally or in email exchanges without formal documentation, are a common source of disputes and complications. A co-founder who was promised 10% but received 5% in the formal documentation; a contractor who was told they would receive options but was never formally granted them; an advisor who holds a side letter that pre-dates the current Articles. Each of these represents a potential claim that complicates the due diligence process.

Complex Liquidation Preference Stacking

Multiple rounds of financing with participating preferred shareholders can create liquidation preference stacks that dramatically reduce common equity value in all but the best exit scenarios. Where these stacks are not clearly modelled in the cap table, investors cannot accurately assess the economics of the transaction. This is increasingly common in companies that have raised multiple rounds at flat or down valuations and have accumulated significant liquidation preferences.

Too Many Small Shareholders

Companies that raised early capital from a large number of individuals through crowdfunding platforms or informal angel rounds sometimes end up with thirty to fifty shareholders each holding small positions. This creates friction in consent processes, drag-along and tag-along provisions, and future share transfers. Some investors will require a shareholder tidy-up (consolidating or buying out small shareholders) before investing.

Cap Table Example: Fully Diluted Ownership

The following example shows a simplified fully diluted cap table for a company that has completed a seed round and has an option pool in place:

This example is clean because every shareholder is identified, every share class is distinct, the option pool is split between granted and ungranted, and the total reconciles to 100%. In practice, a real cap table would also show vesting schedules for founder shares and option holders, the per-share price paid at each round, and the liquidation preference amounts for preference shareholders.

Cleaning Up a Messy Cap Table Before a Fundraise

A cap table cleanup has three components: a legal audit, a records reconciliation, and a remediation process. The typical timeline for a moderately complex cleanup is six to twelve weeks. The costs depend on complexity but typically run between £5,000 and £25,000 in legal fees. This is significantly less than the cost of dealing with the same issues under a transaction timeline.

Step 1: Legal Audit

Engage a startup-focused corporate lawyer to review all share issuance documents, option agreements, shareholder agreements, convertible notes, and the Companies House register. The output should be a gap analysis identifying every document that is missing, inconsistent, or incorrectly filed.

Step 2: Records Reconciliation

Build or update the internal cap table to reflect the actual documented position (not the assumed position). Every discrepancy between the internal cap table and the Companies House register must be identified and explained.

Step 3: Remediation

Address each issue in priority order. Priority issues (those that will block a transaction) are: missing vesting agreements, unforfeited departed-employee options that should have lapsed, and convertibles that need to be formally documented or converted. Secondary issues (those that will slow but not block a transaction) are: minor Companies House filing delays, option grants that need formal HMRC valuation sign-off, and informal arrangements that need to be documented.

What Investors Look for in Cap Table Due Diligence

When an investor reviews a cap table in due diligence, they are looking for: accuracy (does the cap table match the Companies House register and underlying documents), completeness (are all share classes, options, warrants, and convertibles included), consistency (do the vesting schedules and option terms match the employment agreements and grant letters), and economic analysis (what does each class of share receive in various exit scenarios, and is the liquidation preference structure fair and sustainable).

Key Takeaways

• Cap table problems are one of the most common causes of deal delay and deal failure in early-stage financings. The time to fix them is before starting investor conversations.
• A clean cap table has all share classes documented, the option pool accurately split between granted and ungranted, all shareholder agreements in place, all convertibles documented, and the Companies House register matching the internal records.
• The most common problems are: missing vesting agreements on founder shares, unforfeited options for departed employees, informal equity promises, complex liquidation preference stacks, and too many small shareholders.
• Cap table cleanup involves three steps: legal audit, records reconciliation, and remediation. Budget six to twelve weeks and £5,000 to £25,000 in legal costs for a moderately complex cleanup.
• The fully diluted cap table must clearly show every class of shares, all option grants, all convertibles, and the economic waterfall in exit scenarios.
• Investors look for accuracy (matches underlying documents), completeness (all instruments included), consistency (option terms match grant letters), and economic analysis (exit waterfall is clear).
• The most effective pre-fundraise action is a line-by-line reconciliation of the internal cap table against the Companies House register. If they do not match, fix the discrepancies before investor engagement begins.
