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.

Refounded in March 2024 after Microsoft hired co-founders Mustafa Suleyman and Karen Simonyan plus most staff in a roughly $650M licensing deal, Inflection pivoted from the Pi consumer assistant to enterprise AI under CEO Sean White. The Palo Alto lab now sells Inflection for Enterprise, letting regulated-industry customers fine-tune Inflection-2.5 and successor models on Azure. Total funding sits near $1.56B (Greylock, Microsoft, Nvidia, Reid Hoffman), and White says no fresh raise is needed. Recent moves include the BoostKPI acquisition and a push into empathetic customer-support and internal-employee agents.

Equity comp at Inflection AI
- In March 2024, Microsoft hired most of Inflection's team (including co-founders Mustafa Suleyman and Karén Simonyan) and licensed Inflection's technology in a deal valued at approximately $650 million. Inflection continued as an independent company (rebranded to focus on enterprise AI) under new leadership with Reid Hoffman as chair. Employees who joined before the acquihire held equity in an entity that lost its founding team; remaining equity value depends on the standalone company.

If you are leaving Inflection AI with vested incentive stock options (ISOs), most stock plans give you 90 days from departure to exercise or forfeit them. The calculator works at any valuation: enter your strike and the current 409A fair market value (FMV) or an expected exit price. It computes your window deadline, the alternative minimum tax (AMT) cost of exercising in full, and the partial-exercise share count that maximizes expected after-tax value.
Example: leaving Inflection AI with 5,000 vested ISOs at a $1 strike, with the last reported price at $1.35, exercising all of them inside the 90-day window puts a $1,750 bargain element into one tax year. Above the 2026 federal AMT exemption ($88,100 single, $137,000 married joint), the 28% AMT rate adds roughly $490 on top of regular tax before any state AMT (CA, CO, CT, MN). Exercising fewer shares lowers that bill at the cost of forfeiting the rest; the calculator above finds the count that maximizes expected after-tax value for your exact figures.

Inflection AI equity questions
- I left Inflection AI. 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 Inflection AI'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 Inflection AI grant ISOs, NSOs, or RSUs?
- Equity compensation at Inflection AI 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 Inflection AI 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 Inflection AI shares qualify turns on when you acquired them and the company's asset size at that time.
