At 10%/yr expected growth, the AMT premium outweighs the after-tax gain on every share. Letting the window close avoids the AMT bill.
Net after-tax value vs. shares exercised
Each point is the expected after-tax NPV at your hold horizon if you exercise that many shares now and let the rest expire.

Estimates only. Excludes disqualifying dispositions, NSOs, multi-state moves, and AMT preferences other than ISO bargain elements. Long-term capital gains tax assumes a qualifying disposition (ISO held ≥1 yr from exercise and ≥2 yr from grant); state LTCG follows ordinary brackets except where the state grants preferential treatment (HI, ND, SC, WI, AR, NM) or has a dedicated LTCG-only tax (WA). Assumes you are within the $100K ISO limit (any portion of an annual ISO grant whose FMV at grant exceeds $100K is treated as NSO from the start, §422(d)). State AMT figures are 2025 (next-year values published in late 2026). Not financial advice.
QSBS note. If your shares qualify (typically pre-IPO C-corp grants held 5+ years), a federal rule lets you exclude up to $10M of gain on a future sale from federal tax. That single rule shifts exercise-timing math more than AMT does. (This is §1202 “qualified small-business stock”.) Modeled in beta, not here.
You solved the exercise window. The beta plans what comes after it: the new shares, your remaining equity, hedges, and taxes in one multi-year plan.

Equity comp at Amesite Inc.
- Amesite operates three distinct equity instruments simultaneously: (1) stock options for employees with a vesting period that changed from 2 years in FY2023/FY2024 to 4 years in FY2025, all with 10-year terms; (2) annual RSU grants to directors (worth $100,000 per year) that vest on the one-year anniversary of grant; and (3) a Deferred Fee Plan for Directors under which outside directors may take their quarterly cash retainer as deferred stock units (DSUs, shares issued in lieu of cash that are held and delivered at a future date) instead, with settlement deferred until the director leaves the board or a change in control occurs. The 2018 Equity Incentive Plan provides no automatic acceleration upon a change in control at the plan level; acceleration requires explicit language in individual award agreements.
- Vesting schedule: Employee stock options shifted from 2-year vesting (no cliff documented) in FY2023/FY2024 to 4-year vesting in FY2025. Director RSUs vest on the one-year anniversary of grant..

Amesite Inc. equity questions
- I left Amesite Inc.. How long do I have to exercise my ISOs?
- Most stock plans give you 90 days from your departure date to exercise vested incentive stock options (ISOs); unexercised options are forfeited when the window closes. Tax law is slightly wider: ISO treatment requires you to have been an employee within 3 months of exercise (Internal Revenue Code Section 422(a)(2)), so options exercised under an employer-extended window are taxed as non-qualified stock options (NSOs). Check your grant agreement for Amesite Inc.'s exact terms. The calculator above computes your deadline from your departure date, the alternative minimum tax (AMT) cost of exercising, and the share count that maximizes after-tax value.
- Does Amesite Inc. grant ISOs, NSOs, or RSUs?
- Equity compensation at Amesite Inc. typically takes the form of incentive stock options (ISOs) and non-qualified stock options (NSOs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise.
- Are Amesite Inc. shares eligible for QSBS?
- They might be. Qualified small business stock (QSBS) under Internal Revenue Code Section 1202 can exclude federal tax on much of the gain when shares were acquired at original issuance from a C-corporation while its gross assets were under $50 million, and held at least five years. Whether your Amesite Inc. shares qualify turns on when you acquired them and the company's asset size at that time.
