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.

First Solar, Inc. is an American publicly traded manufacturer of solar panels. First Solar uses rigid thin-film modules for its solar panels, and produces CdTe panels using cadmium telluride (CdTe) as a semiconductor. The predecessor company, Solar Cells, Inc., was founded in 1990 by inventor Harold McMaster. In 1999, Solar Cells, Inc., was purchased by True North Partners, LLC, led by Michael Ahearn, and rebranded as First Solar, Inc.

The company traces to a 1984 venture by glass manufacturer Harold McMaster and now makes thin-film cadmium telluride solar modules rather than the crystalline silicon panels most of the industry produces. That choice is the strategy: the process avoids polysilicon supply chains concentrated in China, which turned into a durable advantage once tariffs and forced-labor import rules began constraining competitors. Modules are sold to utility-scale developers under multi-year contracts, so the order backlog extends visibility well beyond a typical manufacturer. Domestic manufacturing credits under recent energy legislation flow directly to earnings. Headquarters are in Phoenix, Arizona.

If you hold vested First Solar (FSLR) 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 FSLR position at $220.01 is worth $1,100,050. 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.

First Solar equity questions
- How much FSLR 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 FSLR 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 First Solar grant ISOs, NSOs, or RSUs?
- Equity compensation at First Solar typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
