What Is a 10b5-1 Plan and Why Do Executives Use One?

What Is a 10b5-1 Plan and Why Do Executives Use One?

A 10b5-1 plan is a written trading arrangement, adopted at a time when you do not have material nonpublic information, that commits you in advance to buying or selling company stock on set terms. If you follow it, it gives you an affirmative defense against an insider trading claim based on trades made under it.

That is what is a 10b5-1 plan in one paragraph. Now the part that matters more.

It is a defense, not a permission slip. It does not make you immune, it does not override your company's policies, and the 2022 amendments made it considerably harder to use it the way some people used to. The mental model that gets executives in trouble is thinking of the plan as a shield they can raise whenever they want to sell. It is closer to a contract with your past self, and the only version of you that could legally sign it was the one who knew nothing.

What Is a 10b5-1 Plan Solving For?

If you are an executive, you are almost always in possession of something the market does not know. Quarterly numbers before release. A deal in progress. A product that slipped. A customer that is leaving.

Meanwhile most of your net worth is in one stock, and reasonable financial planning says you should be selling some of it regularly.

Those two facts fight each other. Every discretionary sale invites the question of what you knew when you placed it, and that question can be asked years later with the benefit of hindsight and a stock chart.

Rule 10b5-1(c) gives you a way out: decide now, while you are clean, and let the decision execute later whether the news is good or bad. The trade happens because of an instruction you gave when you were uninformed, not because of what you learned since.

The out is narrow. It holds only if the plan meets every condition below, and it can be lost by how you behave after you adopt it.

What Is a 10b5-1 Plan Required to Contain?

A plan qualifies only if it meets each of these.

Adopted without material nonpublic information. When you adopt or modify the plan, you must not be aware of MNPI about the company or its securities. This is the condition that determines timing, and it is why plans are normally adopted during an open trading window.

Adopted in good faith, and operated in good faith. The plan cannot be part of a scheme to evade the prohibitions of the rule, and the 2022 amendments made explicit that the good faith requirement runs for the life of the plan, not just at adoption. Adopting a plan and then timing a press release around its trades is the behavior that language is aimed at.

No later influence over the trades. The plan must specify the amount, price, and date, or provide a formula, or delegate discretion to a third party who does not have MNPI. Once it is running, you cannot direct how or when it executes. Calling your broker to nudge a sale defeats the whole arrangement.

The Cooling-Off Periods

The single biggest practical change from the 2022 amendments, effective in February 2023, is that a plan no longer starts trading when you say so.

For directors and officers, the cooling-off period is the later of 90 days after adoption or modification, or two business days after the company files its financial results for the fiscal quarter in which the plan was adopted or modified. That second prong is capped at 120 days.

For everyone else other than the company itself, the cooling-off period is 30 days.

Two consequences follow, and both surprise people.

First, a plan adopted right before an earnings release for a well-timed sale is not going to help you, because the clock has not run.

Second, modification counts. In many circumstances, changing a plan is treated as terminating it and adopting a new one, which starts a fresh cooling-off period. Executives who like to adjust their plans discover that each adjustment costs them months of trading.

The Certification, the Overlap Limit, and the Single-Trade Rule

Three more requirements sit on top.

Directors and officers must include a representation in the plan certifying that, as of adoption, they are not aware of material nonpublic information and are adopting the plan in good faith. Putting that in writing focuses attention in a way a verbal assurance does not.

There are limits on overlapping plans covering open market trades in company securities, with defined exceptions including certain later-commencing plans and sell-to-cover arrangements for tax withholding on vesting equity.

And single-trade plans, meaning plans designed to execute as a single transaction, are limited to one in any twelve-month period.

Separately, the company now discloses in its quarterly and annual reports when directors and officers adopt, modify, or terminate these plans, along with material terms other than pricing. Form 4 filings carry a checkbox indicating reliance on the rule.

Plan adoption used to be quiet. It is not quiet anymore.

What the Plan Does Not Do

Four things, and each one catches somebody.

It does not override your company's own policies. Blackout periods, pre-clearance requirements, and ownership guidelines are separate obligations, and they can be stricter than the rule.

It does not fix concentration. A plan sells stock on a schedule, which is helpful. Whether that schedule matches what your financial plan actually requires is a different question and nobody answers it for you.

It does not address taxes. The timing of your sales interacts with holding periods, the character of the gain, withholding on vested equity, and estimated payments. Those need their own analysis.

It does not solve Section 16. Short-swing profit recovery and reporting obligations apply independently.

Where a Financial Advisor Fits

Capital Area Planning Group is a Washington, DC firm founded in 2024, with a team of roughly six, holding CFP and Series 65 credentials and providing financial planning and investment management to senior managers and executives in tech. That is a narrow client focus, and it lines up with the population that lives inside these rules.

An advisor's role here is bounded, and it is worth being precise about the boundary. The plan itself is a legal document and belongs to counsel and the company's legal department. What an advisor works on is the input: how much stock you should be reducing and over what period, how the schedule interacts with vesting and your cash needs, and what the rest of the portfolio should look like as the concentration comes down. That is the question the plan answers, and answering it badly produces a perfectly compliant plan that sells the wrong amount.

The firm currently shows a small number of verified reviews on its Sam's List profile, so no review count is cited here and that section should not be read as evidence either way. Verify independently, confirm registration and credentials, and ask how many executives with 10b5-1 plans the firm currently advises.

Two limitations. A firm founded in 2024 has a shorter track record than the tenure of the professionals inside it, and those are different things worth asking about separately. And an advisor cannot draft, review, or approve your plan, so you will still need counsel and your company's legal team regardless of who manages your portfolio.

Important disclosures. Registration as an investment adviser does not imply any certain level of skill or training. All investing involves risk, including the possible loss of principal. Nothing here is investment, tax, or legal advice, and nothing here is a recommendation of any firm, security, or strategy. Consider your own circumstances and consult your own professionals before acting.

Frequently Asked Questions

Can I cancel a 10b5-1 plan?

Generally yes, and that is exactly why cancellations draw attention. Terminating a plan is not itself a violation, but a pattern of adopting plans and cancelling them when the news turns can undercut the good faith requirement and is now more visible because of the quarterly disclosure rules. Talk to counsel before terminating, not after.

How long does it take before my 10b5-1 plan can start trading?

For directors and officers, the later of 90 days after adoption, or two business days after the company reports results for the quarter in which the plan was adopted, capped at 120 days. For other employees, 30 days. Plan for a quarter of waiting rather than a few weeks, and adopt well before you expect to need liquidity.

Do I need a 10b5-1 plan if I am not an officer or director?

You may still benefit from one if you regularly have access to material nonpublic information, and many companies encourage them broadly. The cooling-off period is shorter at 30 days, and the certification requirement applies to directors and officers rather than to everyone. Your company's insider trading policy is the place to start.

Does a 10b5-1 plan protect me if I had inside information when I adopted it?

No. Adopting the plan while aware of material nonpublic information defeats the affirmative defense for trades under it. The condition is tested at adoption and again at any modification, which is why plans are adopted in open windows and why the certification exists.

If most of your net worth is in one ticker and you have been waiting for a good moment to sell, the moment is a process, not a date. You can browse financial advisors on Sam's List who work with executives, and bring your company's counsel into the conversation early.
