Can Vested Equity Be Taken Back? What the Documents Actually Say
Sometimes, and the mechanism is rarely the vesting schedule. Repurchase rights let a company buy back vested shares on departure, cause definitions determine the price and whether unvested shares survive, and short post-termination exercise windows can make vested options worthless. All three sit in documents most founders skim.
Vesting is not the clause that decides this
Most founders can recite their vesting schedule and could not tell you what happens to vested shares if they leave in year three after a disagreement with the board.
Vesting governs when equity is earned. A separate set of provisions governs what happens to earned equity when the relationship ends, and those are the ones that produce the outcomes people describe as having their equity taken back.
Three mechanisms do most of the work.
Repurchase rights. The company reserves a right to buy back shares on termination. Sometimes only unvested shares, which is uncontroversial. Sometimes vested shares as well, at a price that may be fair market value or, in a termination for cause, the original purchase price. That second version is where the real risk sits, and it is often described in a single sentence.
Cause definitions. Whether a departure is for cause changes both the price and, in some agreements, whether vested equity survives at all. A narrow definition covering fraud and criminal conduct is normal. A broad one covering failure to perform duties to the satisfaction of the board is a different instrument entirely.
Exercise windows. Vested options must be exercised to become shares. A short window after departure, combined with an exercise price and a tax bill, can make vested options practically unusable.
What to check, in the order it matters
Does the company have a repurchase right over vested shares? If yes, at what price, and does the price change with the reason for departure? Fair market value repurchase is a liquidity mechanism. Repurchase at original cost after years of work is a forfeiture with a different name.
How is cause defined? Read the actual list. Ask what happens on a good faith disagreement about strategy, on a board decision to change the CEO, and on a termination without any allegation of misconduct. Those three scenarios are far more common than fraud.
Who decides that cause exists? A definition that leaves the determination to the board's sole discretion is materially weaker than one requiring a specified process or an objective standard.
How long is the post-termination exercise window? A short default window is common and it is negotiable. Extending it is one of the highest value asks available to an employee or a departing founder, and it costs the company very little.
Does acceleration exist, and on what trigger? Single trigger accelerates on a change of control. Double trigger requires both the change of control and a termination afterwards. Acquirers generally prefer double trigger, which is why the negotiating moment is the financing rather than the acquisition.
Where do these terms live? The term sheet summarizes. The equity incentive plan, the option grant, the stock purchase agreement, and the shareholders agreement control. Read the operative documents.
The founder-specific version
Founders often hold shares purchased at formation subject to reverse vesting, rather than options. That structure has different mechanics and different tax treatment, and the repurchase right on departure is usually explicit. It is also the structure where an early election on the tax treatment of unvested shares can matter enormously, and where the deadline for making it is short and unforgiving.
What is reasonable to negotiate
The goal is not to remove every protective term. Investors and co-founders have legitimate reasons to want unvested equity returned when someone leaves early, and a founder who resists all of it signals something unhelpful.
What is reasonable to push on is narrower.
Limit repurchase rights to unvested shares. This is the single most valuable change and it is frequently accepted, because the protective purpose is served entirely by unvested equity.
Narrow the cause definition to conduct that would concern any reasonable board: fraud, material breach, criminal conduct, gross negligence. Resist performance-based cause language, which converts an ordinary disagreement into a forfeiture event.
Extend the post-termination exercise window. Low cost to the company, high value to the individual.
Agree acceleration terms at the financing, in writing, rather than assuming they will be handled at an exit when the leverage has moved.
And make sure the documents agree with each other. Inconsistencies between a plan document, a grant, and a shareholders agreement are common, and they resolve badly under pressure.
This is general information rather than legal advice, and the specific answers depend on your documents and jurisdiction. Anything in this category is worth having a lawyer read before signing, because the cost of that review is trivial against what these clauses control.
Frequently asked questions
- Can a company take back vested equity?
- In some structures, yes. A repurchase right can allow the company to buy back vested shares on departure, and the price may depend on whether the departure was for cause. Vested options can also lapse if they are not exercised within a short post-termination window. Vesting alone does not determine whether you keep equity.
- What makes a cause definition dangerous?
- Breadth and who decides. A definition limited to fraud, criminal conduct, or material breach is normal. One extending to failure to perform duties to the board's satisfaction converts an ordinary disagreement into a forfeiture event, particularly when the board has sole discretion to determine that cause exists.
- Why do vested options sometimes end up worthless?
- Because options are not shares. Exercising requires paying the exercise price and often triggers a tax liability, within a window that can be short after departure. Someone who cannot fund that in time loses the option entirely, which is why extending the exercise window is one of the most valuable terms to negotiate.
- When should acceleration be negotiated?
- At the financing, not at the exit. Single trigger acceleration applies on a change of control, while double trigger requires a change of control plus a subsequent termination. Acquirers generally prefer double trigger, so the leverage to agree these terms exists while you are raising rather than while you are being acquired.
