A repurchase option is a clause in your stock agreement that gives the company the right to buy your shares back at a predetermined price when a specific event occurs, most often when you leave. You cannot refuse. If you hold restricted stock in a startup, founder shares, or equity in any private company, a provision like this almost certainly governs what happens to those shares when the relationship ends, and the gap between a well-drafted clause and a default one can be worth a lot of money.
How the Right Actually Works
Think of it as a one-sided call option written into your agreement. The company holds the right; you hold the obligation. When a triggering event happens, the company can force the sale at whatever price the contract specifies, and your consent is not part of the transaction.
The company does not have to pull the trigger. If the event occurs and the company does nothing within the contractual window, the option typically expires and your shares become unrestricted. Some companies forget. Some decide the shares are not worth the cash outlay. Some quietly let the window close as an informal concession to a departing employee. Until that window closes, though, the leverage sits with the company.
Three terms do most of the work in any repurchase provision: what events trigger the right, how the price is calculated, and how long the company has to exercise. Everything else is scaffolding.
One mechanical point worth understanding at the outset. There are two ways a company can reclaim unvested shares. One is a repurchase option the company has to actively exercise. The other is automatic forfeiture, where shares revert to the company the moment you leave. Repurchase options are more common when you actually paid cash for the shares, because the company needs to return your purchase price. Automatic forfeiture is typical for stock awards you received at no cost. The distinction matters: if your agreement uses a repurchase option and the company misses the window, you keep the shares.
What Triggers the Right
The option sits dormant until a specific event activates it. The most common trigger by far is the end of your service relationship with the company, whether that service was as an employee, a consultant, or a board member.
Many agreements sort departures into two categories that carry very different financial outcomes:
- Good leaver events: involuntary termination without cause, death, disability, and sometimes retirement. The departing shareholder receives fair market value for repurchased shares.
- Bad leaver events: voluntary resignation, termination for cause, or breach of a restrictive covenant such as a non-compete or confidentiality agreement. The company repurchases at the original purchase price or par value, which strips away all the appreciation that built up during your tenure.
The dollar gap between these categories can be enormous. A founder who spent four years building a company and leaves as a good leaver might receive shares valued at $50 each. The same founder classified as a bad leaver might receive $0.001 per share. Misreading which bucket your departure falls into is one of the most expensive mistakes in startup equity.
Other triggers appear less often: a shareholder’s bankruptcy, commission of a felony, or failure to hit pre-defined performance targets. Venture investors sometimes negotiate repurchase rights tied to milestones, such as a revenue target or a follow-on round within a set timeframe, so a founder isn’t sitting on a large stake if the business isn’t performing. Companies also use repurchase rights for cap table cleanup before an acquisition, buying out small shareholders to simplify the ownership structure and reduce the number of signatures needed at closing.
Whatever the trigger, the contract should spell out exactly how long the company has to act afterward. Windows of 30 to 90 days are typical. Miss that deadline and the repurchase right usually lapses permanently for that event, and the shares become unrestricted.
What You’ll Be Paid
The pricing formula is the most financially significant term in the provision, and the one most likely to surprise you if you haven’t read your agreement carefully. The three common approaches:
- Original cost or par value. The company buys back shares at whatever you initially paid. For early-stage grants issued at a fraction of a cent per share, this is effectively zero. Standard for unvested shares and bad leaver situations, it functions as a penalty that erases all appreciation.
- Fair market value. The company pays what the shares are worth at the time of repurchase. For private companies, this usually requires a third-party valuation. Standard for good leaver situations.
- Discounted fair market value. Some agreements set the price at a percentage of fair market value, often around 75% to 80%, for departures that don’t fit neatly into good or bad leaver categories. A voluntary resignation without any covenant breach often lands here.
Valuation is the harder question for private company shares, because there is no public market to set the price. Most agreements either specify a formula (a multiple of revenue or EBITDA, say) or require an independent appraisal. Who picks the appraiser, who pays, and what happens if the parties disagree on the result are all details that should be addressed in the agreement but often aren’t. Many private companies also carry a Section 409A valuation refreshed every 12 months or after any material event, and that number frequently becomes the baseline for fair market value calculations. If the most recent 409A valuation is nine months old and the business has changed materially, the stale number may not reflect what your shares are actually worth. A well-drafted agreement states whether the repurchase price uses the most recent 409A valuation, requires a fresh one at the time of repurchase, or applies some other method.
Repurchase Option vs. Right of First Refusal
These two provisions often sit side by side in the same stock agreement and get confused constantly. They solve different problems.
A repurchase option lets the company initiate the buyback. The company decides to exercise after a triggering event, and you have to sell. You don’t choose whether the transaction happens.
A right of first refusal kicks in only when you try to sell your shares to someone else. Before you can complete that sale, you have to offer the shares to the company first, on the same terms the outside buyer proposed. If the company passes, you can sell to the third party. You control when this process starts, by deciding whether to seek a buyer. The ROFR process usually adds about 30 days to any share transfer, since the company needs time to evaluate and formally waive or exercise.
The practical split: a repurchase option protects the company when you leave. A right of first refusal protects the company when you stay but try to sell to someone it doesn’t want on its cap table. Most private company stock agreements include both.
The 83(b) Election Trap
If you receive restricted stock subject to a repurchase option, one of the most consequential decisions you’ll make happens within the first 30 days.
Under federal tax law, when you receive property for services and that property is subject to a substantial risk of forfeiture (an unvested repurchase right qualifies), you aren’t taxed until the restriction lapses, meaning until the shares vest.1Office of the Law Revision Counsel. 26 USC 83 – Property Transferred in Connection With Performance of Services At each vesting date, you owe ordinary income tax on the difference between what you paid and the fair market value at that moment. If the company’s value has grown significantly, you could owe tax on substantial phantom gains without having received any cash.
The alternative is an 83(b) election. You choose to be taxed immediately on the value at the time of grant instead of waiting for vesting. File IRS Form 15620 within 30 days of receiving the shares, and the deadline is not flexible.2Internal Revenue Service. Section 83(b) Election – Form 15620 Miss it, and the election is gone forever for that grant.1Office of the Law Revision Counsel. 26 USC 83 – Property Transferred in Connection With Performance of Services
For early-stage employees who pay a nominal amount for shares worth very little at grant, the 83(b) election is almost always the right move. You pay a small tax bill now, and all future appreciation gets taxed as capital gains when you eventually sell. Without the election, every vesting event triggers ordinary income tax at potentially much higher rates.
Here’s where it connects back to the repurchase right. If you file an 83(b) election and then leave before your shares vest, the company exercises its repurchase option and buys back those unvested shares at cost. You’ve already paid tax on them, and you don’t get a refund. The tax code explicitly provides that if elected property is later forfeited, no deduction is allowed for the forfeiture.1Office of the Law Revision Counsel. 26 USC 83 – Property Transferred in Connection With Performance of Services You may be able to claim a capital loss if the repurchase price is less than what you paid, but the income tax you paid at grant is gone. The 83(b) election is a bet that you’ll stay long enough to vest.
When the Company Can’t Legally Fund the Buyback
A repurchase right is only as valuable as the company’s ability to pay for it. Most states prohibit a corporation from buying back its own shares if doing so would make the company insolvent or impair its capital. Delaware, where most startups incorporate, specifically bars repurchases when the company’s capital is impaired or when the purchase would cause impairment.3Delaware Code Online. Delaware Code Title 8, Chapter 1, Subchapter V – Stock and Dividends
This creates a bind. You leave, the agreement says the company will buy your vested shares at fair market value, but the company doesn’t have the cash and legally can’t deplete its capital to pay you. What happens next depends on the contract. Some agreements let the company pay in installments or issue a promissory note. Others state that the repurchase right lapses if the company can’t legally fund it, meaning you keep your shares but remain a minority shareholder in a private company with no market for your stock.
If you’re negotiating an equity agreement, press on this point. Ask what happens if the company can’t fund the repurchase within the exercise window. A promissory note with a defined payment schedule and interest rate beats an open-ended promise. An agreement silent on funding constraints leaves you in the worst position: neither cashed out nor truly free to sell elsewhere.
What Happens in an Acquisition
Repurchase rights interact closely with change-of-control provisions. If the company gets acquired, what happens to the unvested shares the company could otherwise repurchase?
Under single-trigger acceleration, all unvested shares vest immediately on the acquisition, which eliminates the company’s repurchase right before the acquirer takes over. This is rare in modern agreements because acquirers don’t want the entire equity pool to cash out at closing and lose its retention value.
Double-trigger acceleration is far more common. It requires two events: the acquisition itself, plus your involuntary termination (usually without cause) within a defined period afterward, typically 9 to 18 months. Only if both fire do your unvested shares accelerate. This protects you from losing equity because the acquirer restructured, while still keeping you incentivized to stay through the transition.
The overlooked piece: double-trigger acceleration only works if the acquirer actually assumes or continues your equity awards. If the acquirer cancels unvested options as part of the deal, there’s nothing left to accelerate when the second trigger fires. A strong agreement addresses this directly, requiring that if the acquirer doesn’t assume the awards, acceleration happens at closing as if a single trigger applied.
One boundary worth flagging. The repurchase option discussed throughout this article is the contractual right embedded in private company stock agreements. Public company share buyback programs, where a board authorizes repurchases on the open market under a safe harbor framework for timing, price, volume, and broker use,4eCFR. 17 CFR 240.10b-18 – Purchases of Certain Equity Securities by the Issuer are a different mechanism entirely. Nobody is forced to sell in that setting. If you hold public company stock, the rules governing your shares are not the ones described here.
