Post-Exit Lockup Management: What to Do in the 180-Day Window

The typical IPO lockup is 180 days during which insiders (executives, directors, employees, early investors) cannot sell their shares. The period begins on the IPO pricing date and ends exactly 180 calendar days later. Some lockups have staggered release provisions, early release based on price performance, or extended hold periods for specific holders, but the 180-day baseline is standard.

For employees and executives, the lockup period is a planning window. The stock is locked, so decisions about how to manage the position after the lockup expires are made in a context where current selling is not an option. This produces better decisions than the post-lockup moment when the stock is suddenly sellable and emotion dominates.

This article walks through the specific moves a newly-public executive should make during the 180-day lockup, the risks that emerge during the window, and the transition from lockup to post-lockup execution.

The 180-Day Standard and Its Variations

Underwriters and the SEC establish lockups as part of IPO documentation. Standard terms:

• 180 calendar days from IPO pricing: most common.
• Directors, officers, and certain key employees covered: typically 10-50 people.
• Early release provisions: some lockups release 25-50% of shares if the stock trades above a threshold (typically 25-40% above IPO price) for a sustained period.
• Underwriter waiver: underwriters can waive lockup early, typically after 90 days, at their discretion.
• Post-lockup staggered release: some plans release 25% at 90 days, 50% at 180 days, 75% at 270 days, 100% at 360 days.

Lockups also cover restricted stock units settled during the lockup (shares vest but cannot be sold) and options exercised during the lockup (exercise is allowed but resulting shares are locked).

Some deals have extended lockups. Founder-focused lockups of 365 days or 720 days are increasingly common, particularly for companies with concentrated founder stakes. These reflect both underwriter preference and founder commitment signaling.

The Early Moves: Days 1-30 Post-IPO

First 30 days post-IPO priorities:

1. Confirm tax-withholding and estimated payments. IPO-related RSU settlements trigger ordinary income with supplemental withholding. Confirm the gross amount withheld and the balance owed. Underpayment penalties under §6654 compound quickly; get ahead of Q3/Q4 estimated payments.

2. Establish banking and cash infrastructure. Newly-public executives often receive cash from partial RSU settlements (sell-to-cover or net-share). Ensure the cash is parked in insured accounts pending investment decisions.

3. Engage financial advisor or family office. If not yet in place, begin interviews. Most MFOs can onboard during the 180-day window, providing the framework for post-lockup execution.

4. Review estate plan. Post-IPO valuations make prior estate plans obsolete. Schedule review within 30 days.

5. Begin 10b5-1 plan preparation. Rule 10b5-1(c)(1) plans require 90-day minimum cooling-off between establishment and first trade. Plan started on day 30 can trade starting day 120, before lockup ends.

The 10b5-1 Plan Design

Rule 10b5-1(c)(1) provides an affirmative defense against insider-trading liability if the trading plan is established while the insider does not have material non-public information.

Post-SEC 2022 rule amendments:

• 90-day cooling-off period for officers and directors before the first trade.
• 30-day cooling-off period for non-officer insiders.
• Single-trade plans (one sale) require the same cooling-off periods and cannot be used to modify existing plans.
• Good faith operation required; cannot be modified to avoid the cooling-off if MNPI exists.
• Public disclosure of plan establishment for §16 officers and directors through Form 4 disclosures.

A well-designed 10b5-1 plan for a newly-public executive typically covers:

• 24-month sale schedule with monthly or quarterly trades.
• Sell rules based on price, date, or combination.
• Hedge-against-blackout provisions (suspending trades during blackouts).
• Provisions for amendment on specific circumstances.

The plan is drafted by securities counsel in coordination with a broker. Legal fees: $10K-$40K for initial setup.

Diversification Planning During Lockup

With shares locked, the executive cannot sell. But the 180-day window is when the diversification plan gets built:

1. Target concentration percentage. A post-IPO target of 15-25% of net worth in the company stock is typical, declining over 3-5 years to 5-10%. Specific target depends on personal risk tolerance and financial needs.

2. Sale-schedule design. Working backward from the target, determine how many shares to sell per quarter to reach the target in 24-36 months. 10b5-1 plan codifies the schedule.

3. Allocation of proceeds. Pre-plan where the proceeds go: diversified public equity, fixed income, alternatives, real estate, charitable vehicle. Decisions made during lockup execute smoothly post-lockup.

4. Hedging for the non-sold portion. Collars, protective puts, or variable prepaid forwards can hedge the remaining concentrated stake. Structuring these requires post-lockup execution but planning during lockup.

5. §721 exchange fund contribution. Exchange funds can accept concentrated stock at or after lockup end. The 7-year hold and 40-50 bps annual fee produce a diversified portfolio without immediate gain recognition. Plan the contribution during lockup.

Charitable Planning During Lockup

Appreciated public stock can be gifted to charity after IPO. During lockup, the stock is restricted and gifts are constrained, but planning proceeds:

1. DAF or foundation establishment. Set up the giving vehicle during lockup. Post-lockup, first gifts can execute immediately.

2. Target giving amount. Bunching several years of charitable intent into the high-AGI IPO year captures the deduction at high marginal rates. Plan the total amount and deployment schedule.

3. Qualified appraisal preparation. Gifts over $5,000 require qualified appraisals under §170(f)(11). For public stock with exchange prices, the qualified-appraisal process is straightforward but takes 2-4 weeks. Start before gift execution.

4. Bunching strategy. Set up the DAF to receive $5M-$10M in the IPO year for grant-out over 5-10 years. High-AGI-year deduction captured immediately.

Estate Planning During Lockup

Post-IPO valuations are higher than pre-IPO. Estate plans drafted on pre-IPO valuations should be refreshed:

1. Updated balance sheet and projections. Family office or wealth advisor provides current position-size projections.

2. GRAT strategies for concentrated stock. Post-IPO volatility makes GRATs particularly effective. Short-term (2-year) rolling GRATs capture appreciation above the §7520 hurdle rate without using additional exemption.

3. Dynasty trust funding. Transfers to pre-funded dynasty trusts during lockup use current valuation (often elevated from IPO) and current exemption.

4. Spousal gifts. Unlimited marital deduction under §2523 for citizen spouse. Equalize ownership to optimize both spouses’ exemptions.

5. Generation-skipping transfers. Allocate GST exemption to skip-person trusts. 2025 exemption is $13.99M scheduled to drop in 2026.

Risks During the Lockup

Several risks emerge during the lockup window:

1. Price drop through lockup. The stock can fall 30-60% during the 180 days. The executive cannot sell to limit downside. Hedging is constrained during lockup.

2. Underwriter waiver or early release. Some lockups allow early release. The executive may suddenly be sellable weeks earlier than expected, disrupting planning.

3. Rule 144 constraints post-lockup. Rule 144 volume limits apply to affiliates (officers, directors, 10% holders). Affiliate sales limited to 1% of outstanding shares in any 3-month period plus filing requirements.

4. Public disclosure obligations. §16 officers and directors file Form 4 within 2 business days of insider trades. Plan-based trades are generally exempt from §16(b) short-swing liability, but reporting still applies.

5. Tax timing risk. The IPO-year tax bill is due by April 15 of the following year. If the stock drops significantly, the executive may need to sell more shares than planned to cover taxes. The lockup prevents this; estimated payments must be covered from other liquidity.

The Transition to Post-Lockup Execution

The week before lockup expiration:

1. Confirm 10b5-1 plan is active and ready. First trades should execute on schedule.

2. Broker relationship coordinated. The broker executing trades should have clear instructions on price targets, trade sizing, and compliance requirements.

3. Tax-withholding strategy reviewed. Post-lockup sales generate capital gain taxed at long-term rates for shares held over one year. Plan estimated payments accordingly.

4. Charitable gifts pre-positioned. If gifts will execute at lockup expiration, the receiving charity or DAF account should be open and ready.

5. Family and advisor communication. Everyone involved in decisions should know the schedule and understand what executes when.

Common Lockup-Period Mistakes

1. Treating the lockup as nothing-to-do time. The 180-day window is the most productive planning period. Wasting it produces rushed post-lockup decisions.

2. Setting up 10b5-1 plan too late. 90-day cooling-off means plans established after day 90 of lockup cannot execute until after lockup ends plus the cooling-off. Start early.

3. Under-estimating IPO-year tax. Supplemental withholding at 37% federal is usually insufficient for executive-level income. Underpayment penalties compound.

4. Skipping estate plan refresh. Pre-IPO plan doesn’t match post-IPO reality. Heirs pay the price of deferred update.

5. Over-committing to real estate and lifestyle during lockup. Cash feels abundant from partial settlements; commitments made during lockup compound into obligations that constrain post-lockup choices.

Frequently Asked

Can I sell a portion of my shares under the 144 rule during lockup? No. The lockup is a contractual restriction separate from Rule 144. Lockup applies to all covered shares regardless of 144 eligibility.

What if my company goes through a secondary offering during lockup? Insiders may be given the opportunity to sell into the secondary at the secondary’s price. Not always available; specific terms vary.

Can I set up the 10b5-1 plan before the IPO? Yes, in theory. The plan must be established at a time when the insider does not have MNPI. Pre-IPO, the insider has significant MNPI about the company. Post-IPO, pre-lockup-end is the clean window.

What about pledging shares during lockup? Many IPO lockups specifically prohibit pledging, hedging, or transferring restricted shares. Pledging exceptions require written underwriter consent.

Does Rule 10b5-1(c)(1) require SEC filings? Yes, as amended in 2022. Form 4 reports on trades, and Form 144 reports on affiliate sales. §16 officers and directors also disclose plan establishment in their Form 4 filings. Companies disclose 10b5-1 plans quarterly in 10-Qs and 10-Ks.
