How much FLEX stock is too much?

There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your FLEX position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).

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 a meaningful share of your net worth sits in FLEX, concentration risk is the question. This calculator quantifies drawdown impact at 30 / 50 / 70%, and the trade-off between selling down (tax cost now) versus hedging (option premium drag), auto-filled with FLEX's option-implied volatility.

Example: 5,000 FLEX shares at $116.61 is a $583,050 position. A 30% drawdown costs $174,915; a 50% drawdown costs $291,525; a 70% drawdown costs $408,135. The calculator quantifies the trade-off between selling down (immediate capital-gains tax) and hedging (option premium drag) using FLEX's option-implied volatility and your cost basis.
