The Document That Determines Whether Your Equity Is Real
HR emails you a 14-page PDF called “Restricted Stock Unit Award Agreement.” You’re supposed to sign it. You skim the first paragraph, see phrases like “subject to the terms and conditions of the Plan,” and sign it anyway because the offer is good and you’re starting in two weeks.
You just agreed to something. You’re not sure what.
This is almost universal. Tech workers negotiate salary with spreadsheets and comp calculators, then sign the equity agreement in four minutes flat. That’s backwards — for a mid-level engineer at a public company, RSUs are often 30–50% of total compensation. The agreement isn’t just legal boilerplate. It’s the spec sheet for a significant chunk of your net worth.
Here’s what that document actually says, in plain language, and what questions to ask before you accept.
The Anatomy of a Grant Agreement
A realistic RSU grant looks something like this fictional (but very typical) header:
Grant Date: August 1, 2026
Number of RSUs Granted: 1,500
Vesting Commencement Date: August 1, 2026
Vesting Schedule: 25% on the one-year anniversary of the Vesting Commencement Date; thereafter, 1/16th of the remaining shares each quarter.
Four lines. Everything that matters is in those four lines.
Grant Date vs. Vesting Start Date
These are usually the same date, but not always. If you join in the middle of a quarter and the company does quarterly RSU refreshes, your grant date (when the award was approved by the board) might be October 15, but your vesting commencement date could be retroactively set to October 1.
Why does it matter? Your cliff (more on that in a second) and the entire vesting timeline start from the vesting commencement date, not the grant date. A two-week difference doesn’t matter. A two-month difference absolutely does.
At most large public companies these dates are the same. At startups or companies that do annual refreshes, double-check. If you start July 10 and your agreement says your vesting commencement date is August 1, that’s fine — but know your cliff hits August 1 of next year, not July 10.
The Cliff: What Actually Happens at 12 Months
The 1-year cliff is the single most misunderstood piece of equity compensation. Here’s what it means precisely:
You receive 0 shares before month 12. At exactly month 12, you receive 25% of your total grant at once — the entire first year’s worth. Then you receive the remaining 75% on a quarterly or monthly schedule over the next 3 years.
In concrete terms: 1,500 RSU grant, 4-year vest, 1-year cliff.
- Day 364: you own 0 RSUs
- Day 365 (cliff): you own 375 RSUs
- End of month 15: you own 375 + ~94 = ~469 RSUs (if quarterly after cliff)
- End of year 4: you own all 1,500 RSUs
The cliff exists to protect the company from hiring someone, having them quit in month 11 with nearly a year’s equity, and repeat. From your side, it means leaving before your first anniversary is catastrophically expensive from an equity standpoint. At $40/share, those 375 shares are $15,000. Gone.
This is the number you should have in your head when you’re considering leaving before the cliff. Not “I’ll leave when I’m ready” — but “my cliff is April 15, and it’s worth $15,000 to wait six more weeks.”
Termination: The Two Scenarios That Actually Matter
The grant agreement will have a termination clause. It reads something like:
Upon termination of the Participant’s Continuous Service for any reason, any unvested RSUs shall immediately be cancelled and forfeited without consideration.
That’s the standard language. Let’s break down what it means in practice.
Unvested RSUs at Termination: They’re Gone
The company cancels any RSUs that haven’t vested yet. There’s no grace period, no pro-rata calculation for the current quarter, no severance conversion. If you had 300 RSUs scheduled to vest next month and you’re laid off today, those 300 RSUs disappear.
Some companies grant a “qualifying termination” clause — typically 90 days of additional vesting if you’re laid off involuntarily. Most don’t. Check your agreement specifically. If it’s not there, assume the unvested shares are gone the day your employment ends.
Vested RSUs at Termination: Already Yours
Anything that already vested is yours. For RSUs at a public company, by the time an RSU vests, it’s already been taxed as ordinary income (the company withholds shares or cash to cover taxes at vest). What you hold after vesting is stock you own, full stop.
When you leave, you keep it. You can sell it the next trading day if you want. There’s no “exercise window” like stock options — RSUs don’t expire. You already own the shares.
The only exception: trading windows and Rule 10b5-1 plans if you’re an insider or have MNPI. But that’s a separate issue. For most rank-and-file engineers, your vested shares are yours to sell whenever you want after you leave.
Acceleration: Single-Trigger vs. Double-Trigger
This section of the grant agreement is where reading carefully actually pays off. It covers what happens to your unvested RSUs if the company gets acquired.
Single-Trigger Acceleration
In the event of a Change of Control, 100% of unvested RSUs shall immediately vest.
Single-trigger means: acquisition alone triggers full vesting. The company gets bought, you get all your shares immediately. This sounds great, and it is — for the employee.
Which is exactly why most companies don’t offer it. Single-trigger acceleration makes acquisitions complicated. The acquirer just bought the company and now every engineer’s unvested equity just vested and they can all leave tomorrow with no retention hook. Acquirers hate this.
You’ll mostly see single-trigger at smaller startups, or for C-suite executives who negotiated it specifically.
Double-Trigger Acceleration
In the event of a Change of Control, if the Participant’s Continuous Service is terminated without Cause or for Good Reason within 12 months following such Change of Control, 100% of unvested RSUs shall immediately vest.
Double-trigger requires two things to happen: (1) Change of Control, AND (2) your employment ends involuntarily within a specified window (usually 12–24 months). Both triggers have to fire.
This is the standard for most public tech companies and well-structured startups. It’s actually a reasonable deal: if the acquirer keeps you on and treats you well, you keep vesting under the new company. If they acquire and immediately layoff or restructure away your role, you get the acceleration. It doesn’t punish good acquirers who intend to retain you.
What to look for: Does your agreement have any acceleration clause? Some grants have none — if the company gets acquired and you’re laid off, your unvested shares are just gone. That’s a bad deal. Double-trigger is the minimum you should expect at a well-run company.
The Questions to Ask HR Before You Sign
Most people don’t ask any of these. You should ask at least the first three.
1. What is the vesting commencement date, and is it the same as my start date? If they differ by more than a few days, ask why. This affects when your cliff hits.
2. Is there a qualifying termination provision for involuntary layoffs? Some agreements grant 90–180 days of additional vesting if you’re laid off. Worth knowing.
3. What is the acceleration provision on a Change of Control? Single-trigger, double-trigger, or nothing. This matters enormously if you’re at a company that could be acquired.
4. What is the current 409A valuation or fair market value? Relevant if you’re at a private company — this determines the per-share value for tax purposes. Public company employees can skip this.
5. How are RSUs taxed at vest — share withholding or sell-to-cover? This doesn’t change your tax liability, but it changes whether you end up with fractional shares, cash, or a mix. Some companies let you choose.
6. Are there any lock-up periods post-IPO? If the company is pre-IPO, standard lock-up is 180 days after IPO. You can’t sell during that window even though you own the shares.
What You Can Actually Ignore
The grant agreement will include large sections you can safely skim:
- Definitions section: Usually 2–3 pages defining “Cause,” “Good Reason,” “Change of Control,” and other terms. You need to know these definitions exist, but you don’t need to memorize them unless you’re in an acceleration scenario.
- Plan document references: “Subject to the terms of the 2019 Equity Incentive Plan” — this just means your grant exists within a larger plan. The plan document is even longer. You don’t need it unless something goes wrong.
- Committee discretion clauses: The Compensation Committee can modify the plan. They almost never do in ways that hurt existing grantees, and they can’t retroactively take back vested shares.
- Section 409A compliance language: Required boilerplate for deferred compensation. This doesn’t affect anything you’ll experience day-to-day.
The Two Numbers That Matter
When you’re done reading, you should walk away with exactly two numbers memorized:
-
Your cliff date. The calendar date when you hit the 12-month mark and your first 25% vests. Keep this in your head at all times, especially when you’re thinking about leaving.
-
The value of your unvested shares at current price. This is the real cost of leaving, and it should factor into every career decision you make.
Everything else in the document exists to protect the company in edge cases. The cliff date and unvested value are the numbers that protect you.
Your 2 AM self — the one who just got a great LinkedIn recruiter message — needs these numbers before they say yes to a call.
