What happens to my unvested equity when I leave?
If you hold RSUs or stock options, your severance agreement is not the document that decides what happens to them. Your equity plan document is. This is the single most important thing to understand about equity in a layoff, and it is the thing people most often get wrong, because the severance agreement is the paper in front of them and the plan document is the paper they have never read.
Two separate things can go wrong here, and they have different deadlines. The first is what vests and what does not. The second is what happens to the options you already own once you leave. I will take them in order.
One thing to be clear about up front. This post is about what happens when you are laid off, an involuntary termination. If you are leaving on your own, a resignation, the equity picture can be very different, and it usually cuts against you. Many of the provisions that protect you, including any acceleration or negotiated vesting, can be tied specifically to being let go rather than choosing to leave. Walk out on your own and you can forfeit money that a laid-off person in the same seat gets to keep. If you are weighing a voluntary exit, do not assume the same rules apply. That is its own conversation, and worth having before you give notice.
A note on what this kind of help actually is
Most people picture a financial advisor as someone who picks investments. I do that, but it is not where the real value shows up in a moment like this. The value is having been the co-pilot through situations exactly like this one, many times, across the full arc: the day the news breaks, the stack of choices that follows, the decisions that cannot be undone, and then the years afterward when you find out how those decisions actually landed.
That last part is the part you cannot get from an article or a one-time consultation. I have watched these decisions play out over years. I know which questions turn out to matter, where people stumble, and what the version of this looks like that they were glad they thought through carefully. That accumulated view is what I bring to your situation, so you are not making these calls for the first time alone. Someone in the room has seen how this story tends to go.
What vests and what is forfeited
Most equity vests on a schedule. On the day you separate, anything already vested is generally yours to keep. Anything not yet vested is usually forfeited, unless something in your agreement says otherwise.
That word "usually" is doing a lot of work, and the exceptions are where the money is.
Some plans accelerate vesting on a layoff, meaning unvested shares vest early because of the termination. Some accelerate only in specific situations, most commonly a change in control, where the company is acquired. Some severance agreements negotiate additional vesting as part of the package. And some plans have a retirement provision, where employees past a certain age or years of service keep vesting on shares they would otherwise lose. If you are older or long-tenured, check this one specifically, because it can be worth a great deal and almost nobody knows to look for it.
The only way to know which of these applies to you is to read the plan document and your grant agreements, not the severance offer. If the numbers are large, this is worth having someone read alongside you, because the language is dense and the difference between vesting and forfeiture can be a significant sum.
Now the part that quietly costs the most: the exercise window
Here is the trap that catches more money than forfeited vesting does, because it applies to the options you already earned.
If you hold vested stock options, leaving the company starts a clock. You typically have a limited window after your last day to exercise those options, and if you do not exercise within it, they expire. Gone. These are options you already vested, already own, and they can disappear on a deadline you did not know existed.
That window is often ninety days, but it varies by plan, and the length is written in your plan document. Ninety days sounds like plenty until you are also job hunting, managing health coverage, and trying not to spend your severance. The deadline arrives while you are busy, and expired options do not come back.
Exercising is not automatic and it is not free. To exercise, you generally have to pay the strike price, and depending on the type of option, exercising can create a tax bill in the same year, sometimes a large one and sometimes one that is owed even though you have not sold the shares or received any cash. That means the decision to exercise is itself a cash flow and tax decision, landing at the exact moment your income just stopped. It deserves real attention, not a rushed choice in the final days of the window.
This is where the tax planning matters most, and where I do some of the most useful work. The timing of when you exercise can land the tax in one calendar year or the next, and because your income after a layoff often drops, exercising in the following year can sometimes mean a lower bill on the same shares. Whether that works depends on your situation, the type of option, and the deadlines in your plan, which is exactly why I get on a call with your CPA when the numbers are large. One of us is watching the planning, the other is watching the return, and together we work out whether any of the exercise can shift into a lower-tax year without losing the options themselves.
The people who lose money here are not careless. They are overwhelmed. The severance agreement, the health coverage, the job search, and the tax questions all land at once, and a ninety day clock on options they already owned slips past in the noise.

What to do
Find your equity plan document and your individual grant agreements. Not the severance offer, the plan itself. If you cannot find them, your equity administrator or HR can provide them, and you should ask before your access to internal systems is cut off.
Then answer three questions.
What is already vested and clearly yours. What is unvested and whether any acceleration, negotiated vesting, or retirement provision applies to it. And for any vested options, how long your exercise window is, what exercising will cost you, and what tax it triggers.
One more practical step that people do not think to take. The stock option piece is complicated enough that it is worth a conversation with HR or your equity administrator on its own, separate from everything else in your package. I have had clients set up a meeting for exactly that, just to walk through how their options work, what their window is, and what exercising involves. HR will not always volunteer this, but they will usually walk you through it if you ask, and it is far better to have that conversation while you still have access and time than to piece it together against a deadline.
Those answers can add up to a large number, in either direction, and they are all governed by documents most people never open until it is too late. The exercise window in particular is a one-way door with a specific deadline, which puts it in the same category as the account decisions that cannot be undone.
This is a decision worth seeing in the context of everything else happening at once. The exercise cost, the tax it creates, and the effect on your overall picture can be modeled together, so you are deciding with the full view rather than reacting to a deadline. If you want to walk through your own equity that way, start a conversation.
