When institutional investors close a priced round, they receive three documents that govern the relationship for the life of the company: the Investors' Rights Agreement (IRA), the Right of First Refusal and Co-Sale Agreement (ROFR/Co-Sale Agreement), and the Voting Agreement. Together, these documents define every major decision the company will make until exit — from who sits on the board to whether the founders can sell their shares.

Founders spend enormous attention on the term sheet, which covers valuation, option pool, and board seats. They often spend far less time on the IRA, which is longer, more technical, and contains provisions that become critically important in circumstances that feel abstract at closing. This post focuses on the IRA: what investors are actually receiving, why it matters, and what founders should understand before signing.

Registration Rights: Rarely Used, Expensive When They Are

Registration rights give investors the ability to require the company to register their shares with the SEC so they can be sold in the public markets. There are two types.

Piggyback rights allow investors to include their shares in any registration statement the company files — most relevantly, the IPO registration. If the company registers shares for sale in an IPO, investors with piggyback rights can "piggyback" and include their shares in the same registration. The company cannot prevent this without the investors' consent (subject to underwriter cutback provisions, which allow underwriters to reduce the number of investor shares in the offering if including them would impair the IPO).

Demand rights allow major investors to require the company to file a registration statement specifically so the investor can sell. These are rarely triggered — filing a registration statement is expensive and time-consuming, and most investors prefer to wait for an IPO — but they exist as a backstop right. S-3 demand rights (available to companies that qualify to use the shorter Form S-3) are more commonly exercised because the process is faster and cheaper.

Registration rights also include holdback provisions — restrictions preventing investors from selling shares for a specified period after an IPO (typically 180 days, sometimes 90). This is the "lock-up" you've heard about. Registration rights documents govern the mechanics of these lock-ups.

For most startup founders, registration rights feel theoretical until the IPO preparation process begins. At that point, they become very concrete: the company's underwriters will tell you exactly what investor holdback terms they require, and if the IRA says something different, you have a negotiation problem with your existing investors before the IPO even launches.

Information Rights: What Investors Can See

Information rights are operational, not theoretical. They define what financial and operational data you are contractually obligated to share with your investors — and the consequences of not sharing it.

Standard IRA information rights include:

Annual audited financials, delivered within 90-120 days of fiscal year end. Once your company reaches the stage where an audit is required (typically when investors start asking for it or when preparing for a later-stage raise), the annual financials need to be delivered on schedule. Late delivery is a breach of the IRA.

Monthly or quarterly unaudited financials, typically within 15-30 days after the period ends. These are usually management-prepared and cover income statement, balance sheet, and cash flow. Many IRAs also require a comparison to the annual budget.

Annual budget and operating plan, usually delivered 30 days before the start of each fiscal year. Investors use this to understand capital deployment and plan for follow-on funding decisions.

Inspection rights, which give major investors the right to visit your offices, review your books, and speak with key employees on reasonable notice. These are rarely exercised but exist.

Smaller investors often have limited or no information rights — only investors above a specified ownership threshold (commonly 1% or 5%) receive the full package. This is worth paying attention to when you have a large number of small-check angel investors on your cap table. Managing a broad information rights obligation to dozens of investors creates administrative burden and confidentiality risk.

Information rights typically terminate automatically upon an IPO. After the company is public, information disclosure is governed by SEC rules, not private contractual rights.

Pro-Rata Rights: How Investors Protect Their Ownership

Pro-rata rights — sometimes called preemptive rights or participation rights — give investors the right to purchase their proportional share of any future equity issuance. If you own 10% of the company and the company raises a new round, your pro-rata right gives you the right to buy enough shares in the new round to maintain your 10% stake.

This matters because every new equity issuance dilutes existing stockholders. Pro-rata rights allow investors to choose not to be diluted (by exercising their right and buying in) rather than having dilution imposed on them.

Super pro-rata rights go further: they allow investors to purchase more than their proportional share in a future round. Lead investors — those writing the largest checks — often negotiate super pro-rata rights. A lead investor with super pro-rata rights can effectively crowd out other investors in future rounds, which creates tension when the company wants to bring in new investors at the Series B.

Managing pro-rata rights becomes operationally complex as the cap table grows. When a Series B round is oversubscribed (more demand than the company wants to raise), pro-rata rights from existing investors compete with allocations to new investors. This is a common source of conflict between founders who want to bring in new strategic investors and existing investors exercising their pro-rata rights to maintain ownership.

Right of First Refusal on New Securities

This is distinct from the ROFR/Co-Sale Agreement, which covers secondary transfers of existing shares. The IRA's right of first refusal on new securities gives investors the right to purchase new securities — any future equity issuance — before the company sells those securities to third parties.

In practice: if you want to sell shares to a new investor at $5.00/share in a Series B, your existing IRA investors must first be offered the opportunity to purchase those shares at $5.00/share up to their pro-rata allotment. Only if they decline (or the round is larger than what they'd take) can you sell the remainder to the new investor.

This provision has teeth when existing investors want to buy in but the company wants to dilute them by bringing in a new lead investor. It creates a built-in friction that founders sometimes find frustrating and investors view as basic portfolio protection.

Observer Rights vs. Board Seats: The Distinction Matters

Major investors in a priced round typically receive a board seat — a voting director position that allows them to participate in all board decisions, including approval of major transactions, executive compensation, and annual budgets. Board seats are heavily negotiated at the term sheet stage.

Smaller investors — those writing meaningful but not lead checks — often receive observer rights instead of board seats. An observer can attend all board meetings, receive all board materials, and speak at board meetings. But observers cannot vote. They are not directors. They have no fiduciary duties to the company or its stockholders.

The practical difference is large. Directors can be held personally liable (within Delaware's standards) for breach of their fiduciary duties. Observers cannot. Directors vote on resolutions; observers don't. Directors receive formal legal obligations to maintain confidentiality; observers' confidentiality is contractual.

What founders often miss: observers see everything a director sees. They receive the board package — financial results, competitive analysis, M&A discussions, hiring decisions. If your board is considering an acquisition and you want to manage information carefully, you cannot exclude your observers from those discussions without removing their observer rights entirely (which requires their consent). Choose carefully who receives observer rights. Once granted, observer rights are very difficult to revoke.

Key Man Provisions: The Red Flag to Watch For

Some IRAs — particularly in rounds where investors are concerned about founder concentration risk — include key man provisions. These provisions define certain events triggered by a founder leaving the company: accelerated board meetings, investor veto rights over the replacement hire, or even conversion of the preferred stock into a different security with different rights.

Key man provisions are aggressive and should be resisted. They treat the departure of a founder as a triggering event that gives investors additional powers — often at the worst possible moment, when the company is already in a difficult situation. If you see key man provisions in a proposed IRA, negotiate them out entirely or limit them strictly (for example, only applicable within the first 12 months, only if both co-founders depart simultaneously).

What Terminates the IRA

The IRA typically terminates on the earliest of: (1) an IPO in which the company raises above a specified threshold; (2) a merger or acquisition in which the company is not the surviving entity; or (3) consent of a specified percentage of the investors party to the agreement.

The M&A termination is important. If your company is acquired, most IRA provisions terminate automatically. But some obligations survive — particularly indemnification obligations and certain representations. Understand what survives before you close an acquisition, because surviving obligations can affect what you retain from deal consideration.

Reading the IRA Before You Sign

The IRA runs 20-30 pages in a typical Series A. It's not light reading. But it is the document that governs your investors' rights for the life of the company. The terms in it are not standard in the sense of unchangeable — they're standard in the sense of commonly seen, which means the negotiating range is known and founders who ask for changes get them more often than they expect.

Read the information rights carefully — they define an ongoing obligation you'll have to comply with quarterly for years. Read the pro-rata rights carefully — they affect who can invest in your future rounds and on what terms. Read the observer rights section carefully — it determines who is in the room when you discuss your most sensitive strategic decisions. And always flag key man provisions to your counsel before signing.

These are not hypothetical concerns. They are the contractual infrastructure your company operates under every day until you exit.
