Why this matters before you hand in notice
Equity compensation is often one of the largest financial components of a job, but it's also one of the easiest to lose through simple timing mistakes. Once you resign, the clock usually starts running immediately on both vesting (which stops) and exercise windows (which begin counting down), so reviewing these details before you give notice β not after β gives you room to negotiate your last day or exercise decisions if something looks unfavorable.
Common pitfalls people run into
The most frequent mistake is discovering the exercise deadline only after it has already passed, since many plans give as little as 30 to 90 days. Another common issue is underestimating the cash needed to exercise plus the resulting tax bill, which can be a meaningful expense with no guarantee the shares will hold their value. Finally, employees sometimes assume unvested shares will be paid out in some form, when in most standard agreements they are simply cancelled with no compensation.
Frequently Asked Questions
Can my employer extend the exercise deadline after I leave?
Some companies have discretion to extend the post-termination exercise window, and a number of employers have adopted longer standard windows specifically to reduce this pressure on departing staff, but it is never guaranteed β always check your specific grant agreement or ask HR directly rather than assuming an extension will be offered.
What if I can't afford to exercise my options before the deadline?
Options for this vary by company and country: some brokers or specialty lenders offer financing against vested options, and some companies allow a 'cashless exercise' where shares are sold immediately to cover the cost, but availability isn't universal, so confirm what your specific plan allows well before the deadline.
