Meaning
A provision in a stock option plan allows a holder to purchase shares before the vesting period is complete. An early exercise option converts unvested options into restricted stock that remains subject to the original vesting schedule. It shifts the tax clock by allowing the holder to file an 83(b) election.
Exercise Price
Immediate payment for the shares is required at the time the choice is made. The early exercise option uses the current fair market value as the strike price for the transaction. This requires the holder to commit capital upfront without a guarantee of future liquidity.
The risk remains that the shares may never reach a value higher than the purchase price.
Repurchase Right
Company protections remain in place through a right to buy back unvested shares. If a participant departs before the vesting milestones are reached, the early exercise option subjects the stock to a repurchase at the lower of the original cost or the current fair market value. This mechanism prevents the participant from walking away with shares that have not been earned through service.
It ensures that the equity remains tied to the contribution of the individual.
Tax Timing
Filing a tax election within thirty days of the transaction is a requirement for the holder. By using the early exercise option, the individual establishes the cost basis at a lower valuation. This limits future tax liability to capital gains rates.
Ordinary income rates do not apply to the appreciation after the exercise date. The strategy relies on the expectation that the stock price will increase over time.
