What it means
A founder leaves a startup before a product launch, and the company must check its signed equity terms before deciding what happens to the founder's shares. Calling the departure 'bad' in a conversation does not activate a buyback right.
Leaver provisions typically define categories such as good, bad or intermediate leavers, and law-firm guidance describes how agreements can distinguish misconduct from illness, redundancy or other circumstances, with precise definitions and price formulas that vary by deal. Possible bad-leaver triggers include dismissal for serious misconduct, breach of agreed obligations or voluntary departure during a specified early period, though whether resignation counts depends on the text.
A manager should not assume every person who resigns is a bad leaver, and the agreement should define when the trigger is tested: the date notice is given, employment ends, a breach is established or shares transfer, since a few days around a vesting cliff can change significant value. Vesting determines when equity is earned under the agreed schedule, so unvested options or shares may be forfeited or subject to transfer while already vested holdings can have separate treatment, and the company must read both provisions together.
A bad leaver might be required to transfer shares at a specified price, such as cost, nominal value or a discount to fair market value, and some agreements use different prices for vested and unvested shares. There is no universal 'lower of cost and fair value' rule, so a simple illustration is 10,000 shares subject to a valid agreed buyback price of $1 each, which gives consideration of $10,000.
If the agreement instead uses fair market value, a valuation process is needed and should state the valuation date, expert appointment and dispute process, so the formula follows the contract, not the label. Check who may buy the shares.
It could be the company, other founders or investors, and company share repurchases may be subject to capital-maintenance law and approval requirements, so a transfer mechanism cannot be invented after the event. Notice and exercise periods also matter, because an agreement may give remaining holders a limited time to elect a purchase, and the clock runs from the defined trigger using the required form of notice.
The person leaving may dispute the reason or procedure for termination. An allegation of misconduct is not the same as a proved contractual trigger, so preserve employment evidence and obtain advice before sending a notice that affects equity.
The language should be proportionate to the purpose, since an extremely broad clause that penalises any departure can create legal and commercial disputes, and guidance from corporate advisers stresses balancing founder fairness with company protection. Keep the equity outcome apart from other entitlements and update records only when the transfer is complete.
A bad-leaver clause does not by itself cancel wages owed under employment law, so the two calculations should be kept separate, and the cap table should be updated after a completed transfer, not before, because a proposed repurchase can fail if approvals, signatures or payment are missing. For owners, the practical question is what the signed terms say about this departure, these shares and this buyer, so confirm the trigger, process, valuation and employment obligations before taking action.
In practice
Real-world examples.
Example
A signed founder agreement treats a proved serious misconduct dismissal as a bad-leaver trigger. The board follows the dismissal process in the employment contract and records its evidence. Only then does it serve the notice that lets the company buy back the shares.
Example
A company checks whether early voluntary departure affects unvested options under its actual plan. The plan defines a bad leaver as someone who resigns within twelve months of grant. An employee who resigns after fourteen months falls outside that definition.
Example
A departing holder disputes the valuation date, so the parties use the expert procedure specified in their agreement. An independent valuer values the shares at the date named in the agreement. The price is paid within the period the agreement sets.
Formula
Calculation
Illustrative transfer price = affected shares x price per share specified by a valid agreement
Worked example 1: 10,000 shares x $1 = $10,000, if that price and transfer procedure apply.
Worked example 2 (different prices for vested and unvested shares): a founder was granted 40,000 shares vesting over four years and leaves after one year, so 10,000 shares are vested and 30,000 are unvested. Suppose the agreement says unvested shares return at nominal value of $0.01 and vested shares of a bad leaver are repurchased at a 50% discount to a fair market value of $4.00.
Unvested price = 30,000 x $0.01 = $300.
Vested price = 10,000 x ($4.00 x 50%) = 10,000 x $2.00 = $20,000.
Total = $20,300. These terms are assumptions for illustration, and a real agreement may say something different.Case study
Seen in the real world.
This entirely fictional example follows Horizon Robotics, an invented startup. A co-founder departed during a vesting period and the remaining founders assumed all shares could be bought for nominal value. Their adviser found that only certain unvested shares were covered by that mechanism. They followed the signed process for the affected shares and recorded the result. The case does not imply that every early departure is misconduct.
The adviser read the shareholder agreement and the founder's vesting schedule side by side. Of the departing co-founder's 100,000 shares, 25,000 had vested, and the agreement treated vested shares differently from the 75,000 unvested shares. The founders therefore bought the unvested shares at the price the document specified and negotiated a separate price for the vested ones. Horizon updated its share register only after payment and signature were complete. The founders also revised their agreement, so future departures would be handled with clear definitions and a stated valuation method.
Watch out
Common mistakes.
- Calling someone a bad leaver without confirming a defined contractual trigger.
- Applying one low price to all shares without checking vesting and valuation terms.
- Ignoring employment rights, transfer approvals or required notice periods.
Questions

What is a bad leaver?
A person whose departure meets an adverse equity-plan or shareholder-agreement definition.
What happens to their shares?
The agreement may require forfeiture or transfer at a specified price; the result depends on terms, vesting and law.
What are common triggers?
They can include serious misconduct, defined breaches or early resignation, but only as the relevant documents provide.
