How to sell private company stock? A complete guide

Key takeaways

• Selling private company stock is more complex than selling shares on a public exchange because there is no open market for buyers and sellers to transact freely.
• The two main routes for selling private company shares are company-organized tender offers and independent secondary market transactions.
• Most private companies have the right of first refusal, meaning they must approve any share sale before it can go through.
• The value of private company shares is determined through methods like 409A valuations, recent funding round prices, and comparable company analysis rather than a real-time market price.
• Tax consequences depend on whether you hold shares as a result of exercised options, how long you have held them, and whether any special exemptions apply.
• If you cannot afford to exercise your stock options, two paths exist: option lending and cashless exercise.
• Private company shareholders often wait years for a liquidity event like an IPO or acquisition before they can sell their shares.

This is a common situation for employee shareholders, early investors, and founders. While your shares might look valuable on paper, especially if the company is growing quickly or has recently raised money at a high valuation, actually turning that value into cash usually depends on a specific set of opportunities.

Typically, private company shareholders have to wait for a liquidity event, specifically an IPO or an acquisition, before they can sell. Some companies, however, create earlier opportunities through secondary transactions. Understanding how those transactions work, and what conditions apply, is the starting point for anyone thinking about selling private company shares.

What does it mean to sell private company stock?

When you hold equity in a private company, you own something real, but that ownership does not come with an easy exit. Unlike publicly traded shares, which you can sell on a stock exchange at any time during market hours, private company shares are not listed on any exchange.

How do you sell shares in a private company?

There are two primary ways to sell stock in a private company: through a company-organized tender offer or through a secondary market transaction arranged independently. Each route has meaningful differences in how it is structured, who controls the process, and what it costs you as a seller.

• What is a tender offer and how does it work for sellers?

A tender offer is a company-facilitated liquidity event. The company brings outside investors or a corporate buyer to the table, sets a price per share, and opens a defined window of time during which eligible shareholders can choose to sell some or all of their qualifying shares.

Tender offers are not a regular occurrence. It is entirely at the company's discretion whether to run one, and there are no guarantees they will. If the company does organize one, there are usually eligibility requirements that sellers must meet, such as having been employed for a minimum length of time or having already exercised their options and held the resulting shares for a specific period.

One important concept to understand is oversubscription. This happens when more shareholders want to sell than there are buyers willing to absorb at the set price. In an oversubscribed tender offer, the company may prioritize certain categories of sellers, such as current employees, over others. That means participation is never guaranteed even when a tender offer is in progress.

A tender offer should be open for at least 20 business days under SEC rules. During that window, you have time to review the offer documentation, assess the price, evaluate the eligibility criteria, and consult with a financial or tax advisor before deciding whether to participate.

• What is a secondary transaction and how is it different?

A secondary transaction is a private sale of shares that takes place outside of any company-organized program. Secondary marketplaces connect individual shareholders with accredited investors who want exposure to private companies without waiting for an IPO.

The trade-off is friction and cost. Company-organized transactions are smoother because the company sets the price and manages the logistics. In a standalone secondary transaction, you are responsible for finding a buyer, negotiating a price, and often hiring an attorney and accountant to review the shareholder agreement and sales contract. Transaction fees in secondary markets can run upward of 5% of your gross proceeds, and the price you get may still fall short of what you believe the shares are worth.

Another complication is company approval. Most private companies retain the right of first refusal on any share transfer. That means before your secondary sale can close, the company has the opportunity to step in and buy the shares themselves at the agreed price. If they exercise that right, the sale goes to them, not your intended buyer. If they waive it, the sale can proceed, but the timeline can stretch considerably.

What to consider before selling private company shares?

Before you sell, four factors will shape both whether you can and whether you should.

• Does your company restrict how you can sell your shares?

Most private companies include transfer restrictions in their shareholder agreements. The most common is the right of first refusal, which requires you to offer your shares to the company before approaching outside buyers. Some agreements also include board approval requirements, co-sale rights, and lockup periods. Check your shareholder agreement first, and speak with your CFO or legal counsel to understand what the company will and will not permit before going further.

• What is the bid-ask spread, and why does it matter?

In a secondary sale, the spread is the gap between what buyers are willing to pay and what you want to receive. If buyers are bidding $85 on shares you value at $100, that $15 difference scales quickly across a large share count. Keep in mind that waiting carries its own risk. If the company's valuation drops in a future round, the offer you passed on today may look better in hindsight.

• What are the tax implications of selling private company stock?

Tax treatment depends on how and when you acquired your shares. Exercising and selling in the same transaction is typically taxed as ordinary income. If you exercised in a prior year, any further appreciation is subject to capital gains tax, with long-term rates applying if you have held the shares for more than one year. The QSBS exemption under Section 1202 may allow you to exclude a significant portion of your gain if your company and holding period qualify. Consult a tax advisor before committing to any sale.

• What are your actual liquidity needs right now?

Weigh the value of having cash today against the potential upside of waiting. If you have an immediate financial need or want to reduce concentration risk in your portfolio, selling a portion of your shares may make sense. If the company is on a strong growth trajectory and you can afford to wait, holding could yield a better outcome. Neither choice is universally right, and a financial advisor can help you think through the tradeoffs specific to your situation.

Why is selling private company stock so complicated?

Compared to selling shares in a publicly traded company, selling private company stock involves significantly more friction at every stage of the process.

Start with price discovery. When you own shares in a public company, the price is visible to everyone and updated continuously during market hours. With a private company, there is no such reference point. The most recent 409A valuation gives you an IRS-sanctioned estimate of fair market value, and the per-share price from the last funding round gives you another data point, but neither of those figures is the same as what a buyer will actually pay for your shares today.

Then there is the approval process. Depending on your shareholder agreement, completing a sale may require written consent from the board, a waiver of the right of first refusal from existing investors, and legal review of the transfer documents. Each of those steps adds time.

Add to that the cost of professional advice. Getting an attorney to review your shareholder agreement, analyze the sales contract, and advise you on transfer restrictions. You may also need an accountant to help you understand the tax implications before you commit. These are not optional expenses if you want to protect yourself.

And finally, there is the uncertainty that comes with company-run transactions. A tender offer can be modified or canceled at any time before it closes. If the company pulls the deal, you are back to waiting, no matter how much preparation you did.

How do you calculate the value of shares in a private company?

Unlike public stocks, private company shares do not have a live market price. Valuing them involves a few different reference points, each with its own limitations.

• 409A valuation: This is an independent evaluation of a private corporation's common stock fair market value, usually performed yearly or following a significant funding occurrence. It is the IRS-accepted standard for setting stock option exercise prices and is often used as a baseline for understanding what shares are currently worth. However, the 409A value is typically set conservatively, and the actual price achievable in a secondary sale depends on market demand.

• Preferred stock price from the most recent funding round: When a company raises venture capital, investors pay a per-share price for preferred stock. Dividing the post-money valuation by the total number of fully diluted shares gives you an implied per-share value. Keep in mind that preferred shareholders typically have liquidation preferences and other protections that common shareholders do not, so the implied common share price is usually lower than the preferred price would suggest.

• Comparable company analysis: If publicly traded companies operate in the same space and at a similar scale, their valuation multiples (on revenue, EBITDA, or other metrics) can be used to triangulate an estimated value for the private company. This approach requires judgment and access to reliable financial data from the private company.

• Secondary market pricing: Platforms that facilitate secondary transactions sometimes publish data on recent trades in specific private company shares. If available, this can be the most direct indicator of what buyers are actually willing to pay right now.

What if I cannot afford to exercise my stock options before selling?

One of the most common obstacles people face when trying to sell private company stock is the cost of exercising their stock options in the first place. Before you can sell shares, you have to own them. And owning them requires paying the exercise price, which is the per-share cost set when your options were granted.

For some employees, particularly those with a large number of options or a relatively high exercise price, coming up with the cash upfront can be a genuine barrier. Two mechanisms exist to help work around this.

• Option lending: A lender provides a loan to cover your exercise cost, letting you acquire the shares without paying out of pocket. Terms vary: some lenders require personal recourse, putting your personal assets at risk if the stock loses value. Others take a share of your proceeds at a future liquidity event instead. Either way, you are adding leverage to an already illiquid investment, so weigh the interest cost, repayment terms, and downside risk carefully before committing.

• Cashless exercise: Available in some company-organized tender offers, a cashless exercise lets you sell your options without funding the exercise cost upfront. The proceeds from the sale automatically cover the exercise price, and you receive the net difference. For example, with a $10 strike price and a $50 tender offer price, you net $40 per share with no cash required. This option is only available when the company explicitly permits it, and if the tender offer is oversubscribed and your allocation is cut, the unexercised options simply remain unexercised.

Conclusion

Selling private company stock is not as straightforward as placing a sell order in a brokerage account, but it is far from impossible. The key is understanding the pathways available to you, the restrictions your company has put in place, and the financial and tax consequences of different approaches before you commit to any course of action.

The most important takeaways are these: start by reviewing your shareholder agreement and talking to your company about the options available. If a tender offer is available, give it serious consideration, as it is often the least complicated route. If you are pursuing a secondary sale independently, go in knowing the costs and timeline involved.

Your equity is real. Making the most of it just requires knowing how the process actually works.

Frequently asked questions

1. What happens to my stock options if I leave the company?

When you leave a private company, your vested but unexercised stock options typically enter a post-termination exercise window, which is the period during which you can still exercise them. This window is often 90 days after your last day, though some companies offer extended windows of up to 10 years. If you do not exercise your options before the window closes, they expire worthless. Understanding your post-termination window is one of the most time-sensitive decisions employees face when leaving a private company.

2. What is the difference between a tender offer and a secondary sale?

A tender offer is organized and controlled by the company. The company sets the price, identifies eligible sellers, arranges the buyer, and manages the process. A secondary sale is a private transaction you initiate independently, usually through a secondary marketplace or a direct connection with an investor.

3. Can I sell private company stock at any time?

Not usually. Unlike public stocks, private company shares cannot be freely transferred without meeting certain conditions. Your shareholder agreement likely includes transfer restrictions such as a right of first refusal, board approval requirements, or lockup periods. You can only sell when those conditions are satisfied.
