One stack per ticker (current-employer RSUs, prior-employer holdings, index fund, etc.). Each stack has its own current price, growth assumption, and cost-basis lots.

Estimates only. Not financial advice.
Lock-in-now is deterministic (0%). Plans that wait depend on future prices; risk is near-zero when inventory comfortably exceeds the goal. Volatility: each stack's option-implied vol if a ticker is set, otherwise 30%. Lognormal model; real markets have fatter tails.

Its 2023 acquisition of Horizon Therapeutics for $27.8 billion added rare-disease treatments Tepezza and Krystexxa, which combined for roughly $3 billion in 2025 revenue.

Equity comp at Amgen
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

If you hold vested Amgen (AMGN) shares and need a set amount of cash by a date (a house down payment, tuition, a sabbatical, a business buy-in), the question is which lots to sell and in which tax years to keep the most after tax. This calculator builds the minimum-tax sell schedule across your lots, accounting for federal long-term capital gains, the net investment income tax, and your state.
Example: a 5,000-share AMGN position at $421.51 is worth $2,107,550. Say you need $150,000 of it for a house down payment by next spring. Selling enough shares all in one tax year can push the gain into the higher long-term capital-gains bracket and trigger the 3.8% net investment income tax; spreading the sale across two tax years often nets more. The calculator above finds the minimum-tax sell schedule across your specific lots, basis, goal, and date.

Amgen equity questions
- How much AMGN stock do I sell to fund a goal without overpaying tax?
- It depends on your cost basis, your target amount and date, and how the sale spreads across tax years. Selling vested AMGN shares triggers long-term capital-gains tax, plus the 3.8% net investment income tax and state tax above certain income, and bunching a large sale into one year can push the gain into a higher bracket. The calculator above builds the minimum-tax sell schedule across your lots to net your target amount by your date.
- Does Amgen grant ISOs, NSOs, or RSUs?
- Equity compensation at Amgen typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Amgen RSUs use double-trigger vesting?
- No. Amgen restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
