How much FLEX 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 FLEX 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 Flex grant ISOs, NSOs, or RSUs?

Equity compensation at Flex typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.

Do Flex RSUs use double-trigger vesting?

Yes. Flex restricted stock units (RSUs) vest only when two things both happen: the time-based schedule completes, and the company has a liquidity event such as an initial public offering (IPO) or an acquisition. Until both occur you do not own the shares and owe no tax on them.

Founded in Silicon Valley in 1969 and later redomiciled to Singapore, the company builds products other companies design, running electronics manufacturing for customers across automotive, medical, industrial, and cloud infrastructure. Contract manufacturing is a scale business with thin margins, so the strategy has been to move up into higher-value segments where engineering content and regulatory qualification make a customer harder to move. Medical devices and automotive electronics carry longer design cycles and stickier relationships than consumer hardware. Data-center power and cooling products have become the growth line. Headquarters are in Austin, Texas.

Equity comp at Flex

Flex Ltd's 2017 Equity Incentive Plan uses double-trigger vesting for RSUs and other equity awards. Double trigger means unvested awards only accelerate (vest immediately) if both conditions occur: a change of control of the company, and either the awards are not converted, assumed, or replaced by the acquiring or successor company, or the award holder is involuntarily terminated within a designated window following the change of control. A change of control alone, with awards assumed by the successor, does not trigger acceleration.
RSUs use double-trigger vesting. Two things must both happen before the shares are yours: (1) the normal time-based vesting completes, and (2) the company has a liquidity event (an IPO or an acquisition). Until both happen, you do not yet own the shares and you do not owe tax on them.

If you hold vested Flex (FLEX) 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 FLEX position at $116.61 is worth $583,050. 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.
