Secondary Sales: What Investors Should Know Before Buying Private Company Shares

Companies are staying private longer. Founders, employees, and early investors increasingly need liquidity before a traditional exit. Secondary sales have become a mainstream path to that liquidity, but buying shares in a secondary transaction is meaningfully different from participating in a primary financing round.

A company's bylaws, investor rights agreement, ROFR and co-sale agreement, restricted stock purchase agreements, stock incentive plan, and other governance documents can all affect whether a secondary sale closes, how long it takes, and what the deal looks like on the other side. Companies want control over who joins their cap table, particularly to keep out competitors and bad actors, but also simply to maintain a cap table of known insiders. That means buyers face a process that has no equivalent in primary investing.

Here's what to understand before you wire.

Right of First Refusal

Under market-standard terms, the company typically has the first right to purchase shares from a selling founder or employee at the proposed price. That right is often followed by a secondary refusal right held by existing investors.

When you account for notice delivery, board review, and investor election windows running sequentially, the total ROFR process can stretch to 60 days or more. Build this timeline into your expectations before you commit to closing dates.

Board and Company Consent

Stock plans and bylaws frequently require board approval for any share transfer, separate from the ROFR process. If the board meets quarterly and approval requires a formal meeting, timing alone can make a deal unfeasible.

Even when the board acts by written consent under DGCL § 141(f), that requires unanimous approval from all directors. Getting every signature quickly is not always straightforward, particularly when investor-designated directors have competing interests in the same transaction.

One additional development: the NVCA venture financing documents were updated in late 2025 to add screening requirements for buyers with foreign government ties or access to sensitive U.S. data. This adds another layer of review before a transfer clears and another reason to ask the company upfront about its approval process before you spend time and legal fees on diligence.

Co-Sale Rights

Co-sale provisions allow existing investors to sell a proportional amount of their shares alongside any selling stockholder. A buyer looking to acquire 50,000 shares from an early employee may end up receiving most of those shares from tagging investors instead, with the employee's allocation reduced to a fraction of the original block.



If the employee can sell only 3,000 shares instead of 50,000, the deal may not be worth the effort and the transaction falls apart. Understand the co-sale structure before you commit to a specific block size.

Joinder Requirements

As a secondary buyer, you will almost certainly be required to sign a joinder to the company's existing stockholder agreements, including the voting agreement, ROFR and co-sale agreement, and investors' rights agreement.

These agreements impose ongoing obligations and restrictions on the shares you acquire. Review the joinder carefully before signing. The obligations follow the shares for as long as you hold them and they will apply when you eventually look to sell.

Limited Information Rights

Unlike investors who participate in a primary financing round, secondary buyers typically receive no information rights, no financial statements, and no board observer seats. You may be making a significant investment with limited visibility into the company's current performance.

If access to financial data is material to your investment thesis, negotiate for it before closing. This is not standard — but it is possible, and it is far easier to negotiate before you sign than after.

Representations, Warranties, and Indemnification

In a secondary sale, the seller is an individual stockholder, not the company. The representations and warranties you receive will be thin compared to what a company provides in a primary round, and the seller's ability to backstop an indemnity claim is limited by their personal financial capacity.

Understand what you're buying with minimal contractual protections and price the risk accordingly.

Valuation Challenges

Pricing secondary shares is difficult without audited financials or a recent 409A valuation. The last preferred-round price may be stale, and the company is under no obligation to share internal projections.

Where possible, negotiate access to key financial data as a condition to closing. Your pricing should reflect current performance instead of a headline number from a financing round that may be two years old.

Restrictions on Resale

The shares you acquire will likely be subject to the same ongoing transfer restrictions that complicated your purchase. When you eventually look to sell, the same ROFR, board consent, and co-sale provisions apply to your exit. Your own future liquidity is not guaranteed.

Forward Contracts

Some secondary transactions use forward contracts to lock in pricing and commit to a future share transfer — useful when the ROFR process, board approval, or other transfer mechanics will take time to resolve. A forward contract lets the parties agree on economic terms now while procedural requirements play out.

But forward contracts in the private company context carry significant risks. If the company or existing investors exercise their ROFR, the forward may never settle. If the company's value changes materially between signing and settlement, one side may be locked into unfavorable economics with limited recourse. During the interim period, the buyer has no stockholder rights, no information access, and no vote.

Any forward contract should clearly address what happens if the underlying transfer is blocked, delayed, or modified by co-sale participation and should allocate the economic risk of a failed closing between the parties before anyone signs.

Frequently Asked Questions

What is a right of first refusal in a secondary sale and how long does it take?
A right of first refusal gives the company (and sometimes existing investors) the right to purchase shares at the proposed price before an outside buyer can acquire them. The ROFR process includes notice delivery, board review, and investor election windows that run sequentially. In practice this process can take 60 days or more, and buyers should build this timeline into their closing expectations.

What is a joinder agreement in a secondary transaction?
A joinder is a document that makes the secondary buyer a party to the company's existing stockholder agreements, such as the voting agreement, ROFR and co-sale agreement, and investors' rights agreement. By signing a joinder, the buyer agrees to all the obligations and transfer restrictions in those agreements. These obligations follow the shares for as long as the buyer holds them.

Do secondary buyers get information rights in a private company?
Not by default. Unlike primary investors, secondary buyers typically receive no contractual information rights, no financial statements, and no board observer access. Buyers who need visibility into company performance should negotiate information rights as a condition to closing before they sign.

What are co-sale rights and how do they affect secondary transactions?
Co-sale rights allow existing investors to sell a proportional amount of their shares alongside any selling stockholder. A buyer targeting a specific block size from an employee may receive most of that block from tagging investors instead, with the employee's allocation significantly reduced. If the resulting block is too small to justify the transaction, the deal falls apart.

What is a forward contract in a secondary sale and what are the risks?
A forward contract allows parties to agree on economic terms for a future share transfer while procedural requirements — ROFR, board approval, co-sale — are resolved. The risks include the possibility that the transfer never closes if ROFR is exercised, that one party is locked into unfavorable economics if the company's value changes, and that the buyer has no stockholder rights during the interim period. Any forward contract should clearly address the economic consequences of a failed closing.

The Bottom Line

Secondary sales can be a valuable path into high-growth private companies. But the process has no equivalent in primary investing and the friction is not accidental. Companies designed these provisions to control their cap tables.

Ask the company upfront about its approval process. Find out whether waivers or shortened notice periods are available. Review every joinder and governance document before signing. Negotiate information rights before closing if visibility into company performance matters to your thesis. And make sure the sale is properly documented in a stock purchase agreement that reflects the negotiated terms.

The buyers who move through secondary transactions efficiently are the ones who understood the process before it started; not the ones who discovered the complexity mid-transaction.
