Equity Compensation

Equity compensation is the bet that employees make on their employer’s future. Instead of pure cash, you accept (partially or fully) shares or options, betting that the company will grow and those shares become valuable. It works brilliantly for successful startups and is worthless for companies that fail.

Why companies offer equity

Equity compensation serves three purposes:

1. Cash preservation: A startup with $2M in the bank can’t afford $150k/year salaries for all employees. Offering 30% of that in options lets the startup hire talent while preserving cash for operations.

2. Incentive alignment: You’re more motivated to work late if the company’s success directly enriches you. Employees who own equity are typically more engaged.

3. Retention: Equity vests over four years, creating a sunk-cost trap. You’ve already waited two years; why leave now and forfeit the remaining 50% of your grant?

From the company’s perspective, equity is cheap relative to cash—it dilutes ownership but costs zero cash (until liquidation).

Forms of equity compensation

Stock options: You have the right to buy shares at a fixed exercise price. No immediate tax consequence. You owe taxes when you exercise (for non-qualified options) or sell (for incentive options). Options are risky (they’re worthless if the company doesn’t grow) but have unlimited upside.

Restricted stock units: You earn the right to receive shares when they vest. At vesting, you owe ordinary income tax on the value. Simpler than options; no exercise mechanics. Lower upside potential since taxes are owed immediately.

Restricted stock: Shares granted outright, with restrictions on sale until vesting. Similar tax treatment to RSUs but slightly different mechanics.

Profit interests (partnerships/LLCs): You earn a percentage of future profits. Used in partnerships and some LLCs instead of equity. Different tax treatment; complex.

Most tech companies use options or RSUs. Options are traditional (and have better tax treatment for ISOs). RSUs are simpler and increasingly popular at public companies.

Equity as part of compensation

A typical startup offer: $120k salary + $240k equity over four years. The equity is valued by taking the current share price × number of shares. So if you get 12,000 shares at $20 per share, that’s a $240k “grant.”

But this valuation is a snapshot. If the company raises a Series B at $50 per share, your $20 shares are now worth $50 each—$600k for the same 12,000 shares. But your vesting schedule is unchanged. You’ve gotten a windfall.

Conversely, if the company falters and the valuation drops to $5 per share, your $240k equity package is now worth $60k. The offer was $360k total comp; you’re actually getting $180k.

This is why equity offers are noisy. The cash component (salary) is real and guaranteed. The equity component is a bet on future growth.

Public vs. private: the risk profile

Public companies: Equity is liquid. You can exercise options, sell shares, and receive cash within days. Risk is lower because you can bail out anytime. Upside is capped at the public stock price.

Private companies: Equity is illiquid. You can’t exercise and sell unless there’s a liquidity event (acquisition or IPO). You’re locked in. Risk is much higher. Upside can be unlimited—if a startup acquires at $500M, your equity is worth 10x what a public company at $50B might offer.

Most startup employees take on the illiquidity risk for the upside potential.

Tax implications

The tax treatment of equity is complex and type-dependent:

• Non-qualified options: Spread at exercise is ordinary income. Sale gains are capital gains. Effective tax rate: 37% + 20% = 57% federal (worst case). But if the stock appreciates significantly post-exercise, the capital gains rate is favorable.

• ISOs: Spread at exercise is not immediately taxed (but is an AMT item). Sale gains can be long-term capital gains if holding period is met. Effective rate: 20% federal (best case). This is why ISOs are preferred for employees.

• RSUs: Vesting is ordinary income. Subsequent gains are capital gains. Effective rate: 37% + 20% = 57% federal for the gain, ordinary rates for the initial vesting.

The tax upside of options (especially ISOs) is why they’re so valuable. An ISO grant worth $1M on paper might be worth $1M in hand after taxes, whereas an RSU grant of the same value might be worth $700k after taxes.

Equity as golden handcuffs

Equity is a retention tool. You’re 3.5 years into a 4-year vest. You have one more year of $200k equity coming. Do you really want to start over at another company and lose it? Most people don’t. Equity is the golden handcuff.

Companies exploit this. They offer large grants but long vesting schedules, knowing that employees won’t leave before the cliff hits and before they’re nearly vested. Some executives view this cynically (tying people to unsustainable jobs) and others pragmatically (alignment + retention).

Equity and your net worth

For most employees, equity is the largest asset on their balance sheet. A startup employee with 10,000 vested options at a company worth $1B is sitting on potentially $500k (assuming a 2% ownership stake per 10k shares). This is much larger than savings.

If the company goes public, that $500k might become $5M. If it fails, it becomes $0. This binary risk profile is why equity compensation can feel high-stakes.

Smart employees diversify (don’t put all net worth in their company’s equity) and sell opportunistically (if company does a secondary offering or IPO and stock surges, sell some to lock in gains).
