What Should an Investor Inspect Before Buying a Stake in a Private Company?

Before buying a stake in a private company, understand what you own, what could change your ownership, and what choices you have if the business or its owners disagree. A strong business story does not explain your share rights or how much control you will have.

Map the Ownership and Capital Structure

Request the current cap table and a fully diluted version showing options, warrants, convertible notes, SAFEs, and other rights to acquire shares. Reconcile it with the stock ledger, charter documents, and past financing records. Ask who owns each class, whether holders have special rights, and what happens if the company grants a promised equity award.

Model a future financing at a lower valuation and ask how it would affect your ownership percentage and voting power. Review preemptive rights, anti-dilution provisions, transfer limits, and any preferred return or liquidation preference that ranks ahead of your stake. Your ownership percentage may mislead if another class receives proceeds first or carries different voting rights.

Read the Rights That Govern Your Stake

Ask for the charter, shareholder or operating agreement, subscription or purchase agreement, investor rights agreement, and amendments. Identify which actions require your consent, including issuing senior securities, taking on significant debt, selling the company, or changing its business. Check your rights to financial information and budgets. Also review inspection rights and participation in future financings.

For a minority position, focus on what happens when owners disagree. Review board appointment or observer rights, drag-along and tag-along provisions, transfer restrictions, and ways to resolve disputes. Ask who can set compensation, approve related-party contracts, and authorize distributions. If management can retain all cash indefinitely, your ownership may offer no practical way to receive value.

Consider How Value Could Reach You

Discuss possible outcomes with management, while treating a sale or public offering as uncertain. Ask whether value might come from distributions, a strategic sale, a management buyout, or another investor purchasing your stake. Find out who controls each path and whether you can sell without approval. Request any existing shareholder liquidity policy and records of past distributions.

Compare the company's earnings and cash generation with the proposed price and terms. If you have limited control over expenses and distributions, consider whether a royalty or other payment structure is worth discussing. Any such structure needs clear accounting definitions, reporting access, and legal review. Ask your attorney and CPA about the documents and their consequences for your situation.

Ask Questions That Expose Control and Dilution

Request written answers along with the documents that support them:

• "What securities or promises could dilute my stake?"
• "Which decisions can I block, and which can management make alone?"
• "What rights do I have to financial records and future financing?"
• "How are executive pay and related-party contracts approved?"
• "What happens if owners disagree or I want to transfer my shares?"
• "What is a realistic path for a minority holder to receive value?"

Red flags include an unreconciled cap table, undocumented share promises, rights that differ from the term sheet, or management unwilling to explain who controls a decision. Resolve and document these issues before closing.
