The AMT credit only recovers in years where regular tax exceeds AMT — typically a year with no ISO exercise. It carries forward indefinitely (Form 8801) and applies in any future tax year where regular tax exceeds AMT.
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.

Equity comp at Lyntris Inc.
- Lyntris was only recently formed: a Delaware LLC organized April 6, 2026, converted to a Delaware corporation May 1, 2026, then combined with two Trive Capital portfolio companies (Accelint and Vitesse) on May 7, 2026, ahead of its July 23, 2026 S-1 filing. Its pre-IPO employee equity is not standard RSUs. Predecessor Accelint granted 'P units' (a profits-interest structure, a form of equity tied to future appreciation rather than a share grant) through FS Management Equity LLC, with about $2.1 million of unrecognized compensation expense on unvested P units as of December 31, 2025, vesting over a weighted-average 3.7 years. Accelint separately adopted an August 15, 2024 Phantom Equity Appreciation Plan, granting phantom units to select employees that pay out only upon a change in control, IPO, or liquidation event while the holder remains employed. No standard double-trigger RSU disclosure was found for post-IPO equity awards.

If you have left Lyntris Inc. (LYNX) with vested incentive stock options (ISOs), most stock plans give you 90 days from your departure date to exercise or forfeit them. Exercising everything at once concentrates the AMT bargain element into a single tax year. This calculator computes your window deadline from your departure date, the alternative minimum tax (AMT) cost of a full exercise at the current trading price, and the partial-exercise share count that maximizes expected after-tax value.
Example: leaving Lyntris Inc. (LYNX) with 5,000 vested ISOs at a $3.79 strike, with the last close at $12.62, exercising all of them inside the 90-day window puts a $44,150 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 $12,362 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.

Lyntris Inc. equity questions
- I left Lyntris 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 Lyntris 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 Lyntris Inc. grant ISOs, NSOs, or RSUs?
- Equity compensation at Lyntris 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.
- When did the Lyntris Inc. IPO lockup expire?
- Lyntris Inc. (LYNX) went public on August 19, 2026. The standard post-IPO lockup runs 180 days, so employee and insider shares generally became sellable around February 15, 2027. Confirm against your own grant paperwork, since some lockups release early or in stages.
