Equity Liquidity Event

For most employees, equity is a promise. They won’t see a penny until there’s a liquidity event—an IPO where they can sell shares on the open market, an acquisition where the buyer assumes or cashes out options, or a secondary offering where investors buy employee stakes at a set price. The event transforms paper wealth into real money.

IPO: the canonical liquidity event

An initial public offering is the original liquidity event. The company lists on an exchange; shares become tradeable on the open market. Employees can then exercise their options (if any are unvested) and sell the resulting shares to public market investors.

The IPO locks in a valuation. If your company IPOs at $50 per share, your $10-strike options suddenly have $40 of intrinsic value per share. You exercise, realize the gain, and potentially sell immediately for cash.

IPOs are rare—only a tiny fraction of funded startups ever go public. But they’re highly visible and reward early employees generously. An engineer at Google with an initial grant of 5,000 options at $5 (circa 2004) saw those options worth over $1M within five years of the IPO.

Acquisition: the more common exit

Most private companies that achieve a liquidity event are acquired, not IPO’d. An acquirer purchases the company for a fixed price, pays off debt, and distributes the remaining proceeds to shareholders and employees (according to the cap table and any equity acceleration terms).

At acquisition, the buyer assumes or cashes out employee equity. Common scenarios:

• Option assumption: The buyer keeps the stock options alive, converts them to buyer’s options at an agreed exchange ratio, and lets them continue vesting. This ties employees to the buyer post-acquisition.
• Cash-out at acquisition: The buyer pays out the value of all vested options (and, if the purchase price is high enough, some unvested options under acceleration clauses) in cash at closing. Cleanest for the buyer, who doesn’t want to retain employee equity liabilities.
• Rollover / earnout: The buyer keeps a portion of equity (maybe 20%) in escrow or ties it to post-acquisition milestones. Employees get partial cash now, partial payout later if earnout targets are hit.

An engineer with 5,000 options at $10 strike who joins a startup acquired at $50 per share realizes $200,000 of intrinsic value (5,000 × $40 spread), before taxes.

Secondary offerings: intermediate exits

A secondary offering is an internal sale where a late-stage private company (usually post-Series C or D) offers employees a chance to sell their vested equity to new investors at a set price. This is a partial liquidity event—you get cash without the company having an exit.

Secondaries are increasingly common and popular with late-stage startups because they:

• Provide employee retention (give them cash to pay down loans, buy houses, etc.)
• Don’t require a full exit
• Provide new capital

Employees can typically sell 10–50% of their vested equity. A late-stage employee with 10,000 vested options who gets a secondary at $100 per share can sell 5,000 shares for $500,000 cash, keeping 5,000 for upside.

Private equity buyouts

When a private equity firm acquires a company, employees’ equity is usually cashed out at the buyout price. Unlike strategic acquisitions (where the buyer is a competitor and wants to retain some equity holders), PE buyers typically clean out all employee equity. The business is restructured, employees might be laid off, and new equity is issued to the PE-backed management team.

Employees see a one-time cash distribution, no long-term equity upside in the PE-owned entity.

Direct listings and DPOs

A newer variant is a direct listing (DL) or direct public offering (DPO), where a private company’s existing shareholders can sell their shares directly into a public market without a traditional IPO roadshow. This is favorable for late-stage employees—they get liquid stock immediately without the traditional IPO lock-up period.

Timing and uncertainty

The critical unknown is when a liquidity event will occur. A startup might promise equity but never exit. After 10 years, your options are still unvested (or vested but worthless). This is the risk side of equity compensation.

Startups often claim “we’re planning an IPO in three years” but don’t deliver. Acquisition timelines are even murkier. Your equity is a bet on a future exit that might never come.

Lock-up periods and tax

Even after a liquidity event, you often can’t immediately sell all your shares. IPOs typically impose 180-day lock-up periods where insiders (employees, directors) can’t sell. Acquisitions may impose escrow periods (6–12 months) before you get the final cash payout.

When you sell, you owe capital gains taxes on any spread between your cost basis (grant date price or exercise price) and the sale price. If you’ve held shares for more than a year, you qualify for long-term capital gains rates (15–20% federal). If less than a year, ordinary income rates apply (up to 37%).

The psychological boost

A liquidity event is a huge moment psychologically. Equity that was abstract and uncertain suddenly becomes real money. Many employees use liquidity events to pay off debt, buy houses, or take a sabbatical. For founders, it often determines their entire financial security.

But the wealth distribution is wildly unequal. Early employees (founders, Series A hires) typically have 100–1000x more equity value than Series D hires. A founder with 2% of a company acquired at $500M makes $10M. An engineer hired in Series D with $200k of equity makes $200k. The lottery nature of startup equity makes liquidity events highly skewed.

Unexpected liquidity events: bankruptcy

The dark side of liquidity events is bankruptcy. A startup that appears solvent (with employee equity) suddenly fails, runs out of cash, and files Chapter 7 or 11. In bankruptcy, equity holders are last in line, after creditors and debt holders. Employees typically walk away with $0.

This is why employee equity in a failing company is worthless, despite being valuable on paper.
