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.
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.

About Matternet, Inc.
Matternet, Inc. (MTTN) is a public Aerospace/Defense company, incorporated in Delaware and headquartered in Mountain View, CA. IPO'd Sep 21, 2026.
OTC; reverse merger with Los Altos Ventures Corp shell closed May 2026, began trading Sept 2026; FAA Type-Certified drone delivery.
Equity grants at Matternet, Inc. typically include incentive stock options (ISOs) and non-qualified stock options (NSOs).
Andreas Raptopoulos founded Matternet in Mountain View, California in 2011 with Dimitar Pachov, Paola Santana, and Darlene Damm. The company builds an autonomous drone delivery network: aircraft, ground stations, and cloud dispatch software that move medical samples and packages between fixed sites. In September 2022, the FAA granted its M2 aircraft Type Certification, a standard airworthiness approval, the first issued to a non-military drone. Matternet went public via a reverse merger (merging into an already-public shell company) with Los Altos Ventures Corp, closing May 22, 2026, and began trading on the OTCQB market as MTTN on September 21, 2026.

Equity comp at Matternet, Inc.
- In May 2026, Matternet became a public company through a reverse merger (combining with an already-public shell company, Los Altos Ventures Corp, instead of running a traditional IPO). Each legacy Matternet share was exchanged for about 2.08 shares of the new public entity, and Matternet raised roughly $33 million in a private placement (new shares sold directly to investors) as part of the deal. On June 30, 2026, Matternet filed an S-1 registering the resale of up to 51,602,243 shares held by existing stockholders, alongside a new 2026 Equity Incentive Plan and 2026 Employee Stock Purchase Plan (675,000 shares reserved). Because the company went public via this route rather than a conventional IPO, equity holders should confirm current lock-up and resale-registration status directly with the company rather than assuming standard IPO liquidity timelines apply.

Matternet, Inc. equity questions
- I left Matternet, 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 Matternet, 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 Matternet, Inc. grant ISOs, NSOs, or RSUs?
- Equity compensation at Matternet, 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 Matternet, Inc. IPO lockup expire?
