What Equity Holders Need to Know Before the IPO Lockup Period Ends
For most equity holders at recently-IPO'd companies, the lockup expiration date is the first time they have had to navigate this kind of financial decision. The equity may represent a significant portion of their net worth. The tax consequences can be substantial. The planning window is finite. And the mechanics of how public equity compensation works are not intuitive until you have been through them once.
This post covers the foundational concepts that equity holders commonly need to understand before the lockup expiration date, organized by what tends to be most consequential.
The Lockup Agreement Creates a Specific Restriction, Not a Permanent One
A lockup agreement is a contractual restriction -- typically 90 to 180 days after the IPO -- that prevents insiders and major shareholders from selling their shares. The restriction exists to prevent a flood of insider selling in the period immediately after the company goes public, which would suppress the stock price during its initial trading period.
When the lockup expires, that contractual restriction lifts. But the lockup expiration is not the only restriction that applies. Company trading policies, blackout windows around earnings announcements, and pre-clearance requirements for executive-level employees may limit when and how you can sell even after the lockup. The company's equity plan administrator or general counsel can tell you exactly what applies to your role.
The Securities and Exchange Commission regulates the trading restrictions that apply to insiders at public companies, and the SEC's investor education resource at investor.gov covers the basics of insider trading rules in plain language.
The Tax Treatment of Your Shares Depends on Grant Type and Holding Period
This is the area where equity holders most commonly arrive under-informed. The tax consequences of selling your shares are not uniform -- they depend on what kind of equity you received, when you exercised or vested, and how long you have held the shares.
Incentive stock options (ISOs), non-qualified stock options (NSOs), and restricted stock units (RSUs) all have different tax event structures. For ISOs, the most favorable tax treatment requires meeting both a one-year-post-exercise and two-year-post-grant holding period. For RSUs, ordinary income is recognized at vest, and capital gains treatment applies to any appreciation after vest. For NSOs, ordinary income is recognized at exercise on the spread.
What this means practically: shares you receive through different grants may have very different tax costs when sold. Some may qualify for long-term capital gains rates. Some may result in ordinary income. Some may have AMT implications from prior exercises. A CPA who specializes in equity compensation can map this out for your specific grant history before any decisions are made.
You Likely Have a Concentrated Position
For employees who have been at a company since early stages, shares received through equity compensation may represent a substantial fraction of their total net worth. Concentration in a single stock is a financial planning concern that is separate from whether the stock itself is good or bad.
The planning question is not whether to diversify but how and when -- with full awareness of the tax consequences, the trading restrictions, and the financial goals involved. Financial planners who work with equity compensation clients are familiar with this tradeoff. The FINRA investor resources on portfolio concentration cover the general principles, and advisors who specialize in concentrated equity positions are equipped to model the specific tradeoffs for a given situation.
The Planning Window Matters as Much as the Expiration Date
Most of the useful work that can be done around lockup expiration happens before the date, not after it. Tax planning that begins six months before expiration has more options available than tax planning that begins two weeks before. Holding period calculations that are done in advance can inform timing decisions. Advisor coordination that happens early allows each professional to do their best work.
The planning window is not unlimited. Advisors -- particularly CPAs during busy periods -- may have limited availability. Early engagement gives everyone, including you, more time to prepare.

What Commonly Surprises First-Time Equity Holders
Several things consistently catch equity holders off guard when approaching lockup expiration for the first time.
The first is the range of post-lockup restrictions that still apply. Many people expect that lockup expiration means immediate, unrestricted ability to sell. In practice, blackout windows, pre-clearance requirements, and volume restrictions under SEC Rule 144 may limit when and how much you can sell even after the contractual lockup lifts. Understanding these restrictions before the date prevents planning around a window that does not actually exist.
The second is how long the tax analysis takes. People often underestimate how much work goes into understanding the tax position for a collection of grants from different periods. Lot-by-lot holding period analysis, AMT carryforward review, multi-state allocation questions -- each can take significant time when done properly. Engaging a CPA six months before lockup expiration gives adequate time; two weeks before does not.
The third is concentration. For employees who have been at a company since early stages, the shares can represent 60, 70, or 80 percent of their liquid net worth. This is a risk management issue that is independent of whether the company is performing well. Advisors who work with equity compensation clients address this regularly, and the planning approaches for managing concentration have well-established frameworks. The surprise is usually how concentrated the position is until someone calculates it.
What Changes When the Lockup Expires
The lockup expiration changes legal flexibility. You gain the ability to sell shares (subject to other restrictions). What it does not do is answer the questions of how much to sell, when, through what structure, with what tax planning, and how any sale fits your broader financial situation. Those questions are best answered before the lockup expires, not after.
The equity compensation event may also be the first significant liquidity event you have experienced. The scale of the decisions is different from routine financial management. The involvement of specialized advisors -- not just a general financial advisor but one with specific equity compensation experience -- is worth the effort to find.
A simple framework for framing this event: the lockup expiration date is not the decision date. It is the date when legal flexibility arrives. The decisions about how to use that flexibility -- sell how much, when, with what tax planning, within what trading restrictions, coordinated with what financial plan -- are made before the date, with professional advisors who have had enough time to do useful analysis. The earlier the preparation begins, the more options are on the table when the date arrives. For equity holders approaching this for the first time, starting the advisor search and the information gathering process three to six months before the lockup expires is the single most actionable step.
