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.

Exelon separated its power generation business in 2022, creating the largest operator of nuclear plants in the United States. Nuclear output is carbon-free and runs continuously, which turned a commoditized asset into a scarce one as data-center operators began contracting directly for clean round-the-clock power. Production tax credits established a revenue floor that changed the risk profile of the fleet. Long-term power purchase agreements with technology companies are the strategic shift. Headquarters are in Baltimore.

Equity comp at Constellation Energy
- Constellation Energy's Change in Control Severance Agreement and Senior Management Severance Plan only trigger accelerated RSU vesting if an employee is involuntarily terminated without cause, or resigns for good reason, within 24 months after a change in control. A change in control alone does not accelerate vesting, meaning both events (the deal closing and a qualifying job loss) must occur.
- 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 Constellation Energy (CEG) 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 CEG position at $257.49 is worth $1,287,450. 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.

Constellation Energy equity questions
- How much CEG 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 CEG 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 Constellation Energy grant ISOs, NSOs, or RSUs?
- Equity compensation at Constellation Energy typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Constellation Energy RSUs use double-trigger vesting?
- Yes. Constellation Energy 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.
