Private Company Cap Table Due Diligence

A cap table that looks simple on day one rarely stays that way. By the time investors begin their review, layers of SAFEs, convertible notes, option grants, and multi-round preferred stock have turned what started as a spreadsheet into a complex ownership record. Any gap, inconsistency, or missing document can delay or derail a deal.

For equity professionals working with private companies, keeping the cap table audit-ready isn't just a year-end exercise. It's a discipline that pays dividends every time a financing, M&A process, or regulatory review comes around. The newly released Private Company Cap Table Due Diligence Checklist, developed for NASPP members, is designed to help companies proactively close those gaps before investors find them.

Why investors scrutinize your cap table so closely

When a sophisticated investor reviews your cap table, they're working through three core questions: Is the equity real and legally authorized? Are there hidden dilution risks or undisclosed claims? And can future rounds and exit scenarios be modeled with confidence? A "no" or "not sure" on any of these becomes a red flag, and red flags slow deals.

Cap table errors don't just slow financing. They can affect valuation, create legal exposure, and surface compliance risk at the worst possible moment. The cost of fixing problems during diligence is almost always higher than addressing them in advance.

What the checklist covers

The checklist is organized around the eight areas investors examine most closely. Here's a quick overview of what's inside:

1. Summary cap table: Issued and fully diluted view, option pool status, founder dilution history, and ownership by round.
2. Security-by-security breakdown: Common, preferred, options, SAFEs, convertible notes, warrants, and all side agreements.
3. Legal backing: Every cap table line matched to a signed agreement, including purchase docs, grant agreements, certificates, and electronic issuances.
4. Board & shareholder approvals: Documentation that each issuance and round was properly authorized by the board and, where required, stockholders.
5. Option plan & 409A compliance: Current and historical 409A valuations, strike price alignment at grant date, and early exercise documentation.
6. Share reconciliation: Authorized vs. issued shares, option pool math, and a fully diluted count that ties across all documents.
7. Convertible modeling: SAFE and note conversion scenarios stress-tested across interest accrual and next-round dilution impacts.
8. Investor rights & preferences: Liquidation preferences, anti-dilution provisions, pro rata rights, participation rights, and voting mechanics.

The red flags investors notice immediately

The checklist also catalogs the most common issues that slow or kill deals. These are worth reviewing now, not during a live process:

• Missing board approval for one or more option grants
• No 409A valuation, or options granted when the 409A was outdated
• SAFEs not tracked consistently or modeled for conversion
• Cap table figures that don't match signed legal documents
• Founder shares that weren't properly vested or issued
• Share issuances that weren't authorized
• Multiple conflicting versions of the cap table in circulation

A clean cap table is a strategic asset

Beyond satisfying investor scrutiny, a well-maintained cap table benefits every team that touches equity, including finance, legal, HR, and leadership. It creates a single source of truth for financial reporting, compensation decisions, scenario modeling, and board discussions. The earlier this discipline is established, the easier it is to maintain as the company grows.
