# How does a secondary sale of private company shares actually work before an IPO?

Selling private pre-IPO shares on the secondary market requires company approval, a willing buyer, and careful payment sequencing since there's no public exchange to rely on.

---


Selling private company shares before an IPO, through what's commonly called a secondary sale, means finding a willing buyer for shares that have no public market and typically can't be transferred without the company's own approval first — unlike a public stock sale, which settles instantly through an exchange, a pre-IPO secondary sale requires navigating the company's transfer restrictions, securing company consent, negotiating a price with no reliable public benchmark, and resolving payment and transfer sequencing entirely between you and the buyer, since there's no exchange infrastructure handling any of it automatically.

This process has become considerably more common and more structured over the past decade, as private companies have stayed private longer and employees and early investors increasingly look for ways to access some liquidity before an eventual IPO or acquisition — but it remains meaningfully more complex and risk-laden than a public market transaction, and understanding the actual mechanics matters before assuming it works anything like selling a public stock through a regular brokerage account.

## Why can't you just sell your private shares to anyone who wants to buy them?

Most private companies include transfer restrictions in their shareholder agreements, stock option plans, or bylaws specifically limiting a shareholder's ability to sell or transfer their shares without the company's prior approval — this exists for legitimate reasons from the company's perspective, including maintaining control over its cap table, preventing shares from ending up with unwanted or disruptive new shareholders, and complying with securities law exemptions that often depend on the company maintaining a limited and known set of shareholders.

This means the very first step in any pre-IPO secondary sale, before even finding a buyer or negotiating a price, is understanding exactly what your specific company's transfer restrictions actually require — some companies have a formal right of first refusal (meaning the company or existing investors get the first opportunity to buy your shares at whatever price you've negotiated with an outside buyer before that outside sale can proceed), while others may prohibit secondary sales entirely without specific board approval, or have no restrictions at all for certain types of shares.

## How do you actually determine a fair price without a public market to reference?

The most common reference point is the company's most recent priced funding round — if the company raised money at a specific valuation within the past year or so, that valuation provides a reasonable, though imperfect, starting point for negotiating a secondary sale price, typically adjusted up or down based on how the company's performance and the broader market have evolved since that round closed. A company that's grown significantly and generated considerable investor enthusiasm since its last round might command a secondary sale price above that round's implied valuation, while a company facing headwinds or operating in a cooling market for its sector might see secondary interest at a meaningful discount to its last official valuation.

Specialized secondary marketplaces that handle regular transaction volume in well-known private companies' shares can also provide useful pricing data points from recent comparable transactions, which is often more current and more reflective of actual market appetite than relying solely on an official valuation that may be many months old by the time you're actually trying to sell. It's worth treating any of these reference points as a starting point for negotiation rather than a precise, objective price the way a quoted public stock price would be.

<p>The company's last funding round valuation, recent comparable secondary transactions if available, and your own sense of the company's current trajectory should all factor into evaluating whether an offered price is reasonable.

## What role does a right of first refusal actually play, and how does it affect your sale?

A right of first refusal gives the company, and sometimes specific existing investors, a defined period after you've negotiated a sale price with an outside buyer to step in and purchase your shares themselves at that same price, effectively matching the outside offer rather than letting it proceed to the external buyer. This exists to let the company maintain some control over who its shareholders ultimately are, and it means your negotiated outside sale isn't necessarily final the moment you and a buyer agree on terms — there's a real possibility the company itself, or an existing investor, exercises this right and ends up as the actual purchaser instead.

This is worth factoring into your expectations from the outset — a right of first refusal doesn't prevent you from eventually selling at the agreed price, but it does mean you may not end up selling to the specific outside buyer you negotiated with, and the process generally takes somewhat longer as a result of this additional approval step built into most private company transfer processes.

## Does payment sequencing create the same "who goes first" risk as other private transactions?

Yes, essentially the same fundamental risk that applies to any private transaction where goods or assets and payment aren't exchanged simultaneously through a trusted intermediary — a seller transferring shares before payment is confirmed risks the buyer simply not paying, while a buyer paying before the transfer is actually completed and approved (including any right of first refusal window) risks paying for shares that never actually transfer to them, or that the company steps in and redirects elsewhere. For a transaction of any meaningful size, this risk is worth addressing explicitly rather than simply trusting the other party, the same basic principle that applies to escrow arrangements in other high-value private transactions covered elsewhere on this blog.

Many established secondary marketplaces address this directly by handling the transaction through their own structured closing process, coordinating the transfer and payment in a way that reduces this sequencing risk for both parties — which is one meaningful advantage of using a reputable, established platform rather than arranging a secondary sale entirely independently with a buyer you found through informal channels, where you'd otherwise need to arrange your own escrow or trusted intermediary to manage exactly this risk.

## What tax consequences should you expect from a secondary sale?

Selling private company shares generally triggers a capital gains tax event, with the specific treatment (short-term versus long-term capital gains rates) depending on how long you've held the shares and your specific tax jurisdiction's rules. For shares acquired through employee stock options specifically, the tax analysis can be considerably more complex, since the type of option (incentive stock options versus non-qualified options, for instance, under US tax rules) affects both when taxable income was or will be recognized and how the eventual sale is taxed, making this an area worth discussing with a tax professional well before actually executing a sale rather than assuming a straightforward capital gains calculation applies uniformly to every situation.

It's also worth factoring tax consequences into your actual decision about whether and how much to sell — a secondary sale that triggers a substantial tax bill in a single year might be worth structuring differently (selling a smaller portion, or timing the sale relative to other income) than simply selling your maximum available amount without considering the resulting tax impact.

## How does this play out for someone actually pursuing a secondary sale?

Call her Ingrid, an early employee at a private technology company who'd accumulated a meaningful equity stake over several years and, facing a personal need for liquidity well before any anticipated IPO, decided to explore a secondary sale of a portion of her vested shares. She began by reviewing her option agreement and discovered the company required formal written consent before she could even approach potential buyers, which she requested and received within a few weeks, along with confirmation that the company retained a right of first refusal on any negotiated sale.

Ingrid connected with a buyer through an established secondary marketplace specializing in the company's sector, negotiating a price modestly below the company's most recent funding round valuation, reflecting some cooling in investor sentiment toward the sector since that round had closed. The company ultimately didn't exercise its right of first refusal, and the sale proceeded to the outside buyer, with the marketplace's own structured closing process handling the coordinated transfer and payment, removing the need for Ingrid to personally arrange an escrow or trust the buyer to pay immediately after she'd transferred her shares. The entire process, from initial consent request to final payment, took a little over two months — longer than Ingrid had initially expected, but considerably smoother than attempting to arrange the same transaction independently with a buyer found through an informal personal connection, which she'd briefly considered before learning about the marketplace option.

## What's the practical takeaway for anyone considering a pre-IPO secondary sale of their shares?

Start by thoroughly understanding your own specific shareholder agreement's transfer restrictions and required approvals, well before approaching any potential buyer. Use an established, reputable secondary marketplace where possible, both for access to more realistic pricing information and for a more secure, structured closing process than arranging the transaction entirely independently. Factor in the realistic possibility of a right of first refusal affecting who you ultimately sell to, plan for a longer timeline than a simple handshake deal might suggest, and consult a tax professional about the specific consequences for your situation before finalizing how much of your position to actually sell.

## Can the company simply refuse to allow a secondary sale at all?

Depending on the specific terms of your shareholder or option agreement, yes — some companies retain broad discretion to deny permission for a secondary sale entirely, not just a right of first refusal on a sale that's otherwise permitted, particularly for earlier-stage companies more concerned about maintaining tight control over their cap table and shareholder base. This is worth understanding clearly before investing significant time in finding a buyer or negotiating terms, since discovering late in the process that the company simply won't permit any secondary transfer at all is a frustrating and avoidable outcome if the restriction could have been identified upfront by reading your agreement carefully or asking the company directly and early.

Some companies, recognizing that long-tenured private status creates real liquidity pressure for employees and early investors, have become more accommodating over time, periodically opening structured liquidity windows allowing employees to sell a limited portion of their vested shares under company-organized terms, sometimes through a company-sponsored tender offer rather than an individually negotiated secondary sale. It's worth asking your company directly whether any such structured program exists or is planned, since this can be a considerably smoother and more predictable path to partial liquidity than pursuing an independent secondary sale against a company that hasn't signaled openness to doing so.

## How does a secondary sale differ from participating in a company-organized tender offer?

A tender offer is a structured, company-organized process where the company itself (or a specific investor, often alongside a new funding round) offers to purchase shares from a broad group of existing shareholders at a set price and within a defined window, rather than an individual shareholder independently finding and negotiating with their own outside buyer. This is generally a simpler, more predictable process for an individual shareholder than an independently arranged secondary sale, since the company has already handled the approval, pricing, and process design — your role is primarily deciding how much, if any, of your eligible shares to tender at the offered price, rather than navigating transfer restrictions, finding a buyer, and negotiating terms yourself.

The tradeoff is that a tender offer's price and terms are set by the company or its process, not individually negotiated, meaning you have less control over price than you might in an independently arranged sale to a specific interested buyer, and participation is often capped at a limited percentage of your holdings rather than allowing you to sell as much as you'd like. For an employee or investor who simply wants some liquidity without navigating the independent secondary sale process described above, participating in a company-organized tender offer, when one is available, is often the more straightforward option worth asking about before pursuing a fully independent secondary transaction.

Either path ultimately depends on the same underlying reality: private company shares are fundamentally less liquid than publicly traded stock, and whatever mechanism you use to access that liquidity — an independently negotiated secondary sale or a company-organized tender offer — involves more friction, more approvals, and more uncertainty about timing and price than simply placing a sell order through a brokerage account. Approaching either option with that realistic expectation from the outset makes for a smoother process than assuming your private shares can be converted to cash on anything close to the speed or simplicity of a public market transaction.
