An IPO lockup period restricts insiders from selling shares for a set window after a company goes public. The restriction exists to prevent early insiders from flooding the market immediately after the IPO and suppressing the stock price during its initial trading period. Lockup agreements typically run 90 to 180 days, though specific terms vary by company and underwriting agreement.
When the lockup expires, the legal restriction on selling lifts. That moment is often treated as a straightforward calendar event, but it is better understood as a decision point that has been approaching for months. The questions worth asking before the lockup ends are usually harder to answer after it does, particularly when tax deadlines and market conditions converge. This article covers the topics equity holders commonly bring to their advisory teams in the months before a lockup expiration.
The Securities and Exchange Commission and investor.gov, the SEC's investor education resource, both provide public materials on insider trading restrictions and lockup agreements that are worth reviewing alongside professional guidance.

What Lockup Expiration Actually Changes
The lockup period restricts when you can sell but does not by itself determine whether selling is appropriate, tax-efficient, or aligned with your broader financial picture. When the lockup expires, you gain legal flexibility but that flexibility does not carry instructions.
Several things happen at lockup expiration that are worth understanding before the date arrives:
Concentrated position risk. For many employees and insiders, shares received through employment compensation represent a large percentage of their net worth. The lockup period can extend that concentration while the stock price is volatile. Some equity holders arrive at lockup expiration with a position that has grown to represent 70 to 90 percent of their liquid assets, a concentration level that most financial planners would flag as a risk management concern.
Trading window constraints. Even after lockup expiration, many public companies operate blackout windows that restrict insider trading around earnings periods. Lockup expiration and trading window open periods may not align, and coordinating with your company's legal counsel about what is and is not permitted at any given time matters before you assume the lockup expiration date is the date you can sell.
Market liquidity timing. When a large number of insiders and early investors reach lockup expiration simultaneously, trading volumes in the stock often increase. The FINRA resources on equity compensation and insider trading provide context on how these events typically play out and what disclosures are involved.
Tax Timing Topics to Clarify With a CPA
Taxes are the most time-sensitive topic at lockup expiration because some decisions have hard deadlines that cannot be extended.
Ordinary income vs. capital gains. The tax treatment of your shares depends on their origin. Shares from incentive stock options (ISOs), non-qualified stock options (NSOs), and restricted stock units (RSUs) are all taxed differently at exercise, at vesting, and at sale. A CPA familiar with equity compensation can map out the tax basis and holding period for each lot, which is the foundation for every other planning conversation.
Short-term vs. long-term capital gains. Shares held for more than one year before sale are taxed at long-term capital gains rates, which are lower than short-term rates. Whether any of your shares qualify for long-term treatment depends on when the holding period began and how it is calculated for each grant type. Some holding periods start at exercise or vesting, not at lockup expiration. Clarifying this before you sell determines how much flexibility you actually have on timing.
Alternative Minimum Tax (AMT) considerations for ISO holders. Exercising ISOs can trigger AMT in the year of exercise, depending on the spread at exercise. If you exercised ISOs before the IPO, your CPA may need to review whether any AMT liability is still relevant and how a sale interacts with the AMT credit carryforward. The IRS publishes guidance on AMT and equity compensation, though the application to specific situations requires professional interpretation.
State tax residency. If you have lived or worked in more than one state since receiving your equity grants, multiple states may have a claim on a portion of the income when you sell. This is a niche area that requires specific professional guidance rather than general research.

Portfolio Concentration Topics to Explore With an Investment Advisor
Concentration in a single stock is a risk management question as much as a return question. The conversations worth having with an investment advisor or financial planner before lockup expiration tend to cluster around a few themes.
What percentage of your net worth does this position represent? There is no universal answer to what concentration level is too high, but advisors working with equity compensation generally use it as a starting point for planning. A position representing 50 percent of your liquid assets is a different planning conversation than one representing 10 percent.
What are your liquidity needs in the next one to three years? Large planned expenses, including home purchases, business investments, or educational costs, affect whether holding or selling makes more sense from a cash flow perspective. An advisor can model scenarios based on your specific timeline and goals without making a recommendation about whether to buy or sell the stock.
Diversification strategies beyond simple selling. Depending on your situation and the size of the position, advisors sometimes discuss structured approaches to concentration management. Exchange funds, charitable strategies, and derivatives-based hedging are examples of tools that professional advisors use with clients holding concentrated equity. Each has its own tax and legal considerations, and none should be pursued without understanding the terms and implications thoroughly.
How this position fits your overall financial picture. For founders and senior executives, the IPO-adjacent equity is often the first major liquidity event of their career. How it fits alongside other assets, income sources, and long-term plans is a question a financial advisor is positioned to help think through, even if they cannot predict how the stock will trade.

Advisor Coordination Topics
Lockup expiration is one of the clearest examples of an event that benefits from coordinated advice across multiple professionals. Tax, legal, and investment decisions at lockup expiration are interconnected, and optimizing one in isolation sometimes creates a problem in another.
CPA and investment advisor coordination. A sale that is optimal from a portfolio concentration standpoint may trigger a tax liability that your CPA would have handled differently with advance notice. Coordinating both perspectives before executing any transaction is worth the time.
Company legal counsel vs. your own attorney. Company legal counsel represents the company's interests, not yours. If your equity compensation agreement has provisions you have not reviewed with your own attorney, lockup expiration is a reasonable time to do that review.
Company-specific trading restrictions. As noted above, trading windows, pre-clearance requirements, and other company-imposed constraints can limit when and how you transact even after lockup expiration. Your company's general counsel or equity plan administrator can clarify what restrictions apply to your specific situation and role.

Questions to Bring to Your Advisory Team
The following questions are worth preparing before meeting with advisors. They are not a substitute for professional guidance but they help focus the conversation and ensure the most relevant topics get addressed.
For your CPA:
- What is the tax basis and holding period for each lot of shares I hold?
- Do any of my shares qualify for long-term capital gains treatment today?
- Are there AMT considerations from prior ISO exercises that affect planning?
- What are the tax consequences of different timing scenarios for a sale?
- What documentation will I need, and when?
For your financial advisor:
- What percentage of my liquid net worth does this position represent?
- How does this position fit my overall financial plan?
- What diversification strategies are worth discussing for a position of this size?
- How do my liquidity needs over the next few years affect the timing question?
For your company's equity plan administrator:
- When exactly does the lockup restriction lift for my grants?
- What trading windows or pre-clearance requirements apply to my role?
- Are there any other contractual restrictions on selling I should be aware of?
Getting Advisor Support Before the Deadline
The conversations above benefit from time. A CPA who learns about a pending lockup expiration two weeks before the date has fewer options than one who has six months to plan. The same is true for investment advisors structuring a diversification approach or attorneys reviewing agreement terms.
The Capivise advisor match connects people navigating equity liquidity events with advisors who specialize in this type of situation. The questions to ask an advisor resource on the site covers how to evaluate whether a given advisor's background fits your specific circumstances.
The lockup expiration date is a deadline, not a decision. The decisions that shape the outcome of that event are made in the months before it, ideally with coordinated professional input. Treating it as a planning milestone rather than a calendar date is the most useful reframe for anyone approaching this event for the first time.

Additional Topics to Research
The SEC's investor education platform at investor.gov has plain-language materials on insider trading rules, holding periods, and equity compensation disclosures that are useful background before engaging advisors. The materials do not replace professional guidance, but they provide a vocabulary and framework that makes professional conversations more productive.
For employees at companies that have recently gone public or are approaching an IPO, the equity compensation planning conversation is often the first time many of these topics have been relevant. The learning curve is steep and the stakes are high. Starting early, with the right professionals, is the most reliable way to avoid decisions that are difficult to undo.
