Direct Answer
Direct answer: Form 144 is a notice of proposed sale filed with the SEC by an affiliate of an issuer who intends to sell restricted or control securities under Rule 144. The SEC states the trigger precisely: if you are an affiliate, you must file a notice with the SEC on Form 144 if the sale involves more than 5,000 shares or the aggregate dollar amount is greater than 50,000 dollars in any three-month period. The filing signals an intention. It does not confirm that any shares were sold, at what price, or on what date, and a Form 144 with no matching Form 4 afterwards may mean the sale never happened.
Key Takeaways
- Rule 144 is a safe harbour, not the only route. The SEC describes it as providing a safe harbour exemption to sellers, and notes that the rule is not the exclusive means for selling restricted or control securities.
- Two categories are covered and they are different. Restricted securities are acquired in unregistered private sales from the issuer or an affiliate. Control securities are those held by an affiliate of the issuing company.
- Buying from an affiliate makes your shares restricted. The SEC states that if you buy securities from a controlling person or affiliate, you take restricted securities even if they were not restricted in the affiliate’s hands.
- The holding period is six months for a reporting company and one year for a non-reporting company, and it applies only to restricted securities.
- The volume formula is the constraint most people get wrong. For an affiliate it is the greater of 1 percent of the outstanding shares of the class, or, if the class is listed on a stock exchange, the greater of 1 percent or the average reported weekly trading volume during the four weeks preceding the Form 144 filing.
- Over-the-counter stocks can only use the 1 percent measurement, which makes the constraint much tighter for thinly traded issuers.
- Non-affiliates who have held restricted securities of a reporting company for at least six months but less than one year may sell if the current public information condition is satisfied. After one year, and having not been an affiliate for at least three months, they can sell without regard to those conditions.
- Form 144 and Form 4 answer different questions. Form 144 is filed before a proposed sale by an affiliate; Form 4 reports a completed transaction by a Section 16 insider.
- Meeting Rule 144 does not by itself free the shares. Only a transfer agent can remove a restrictive legend, and it will generally not do so without the issuer’s consent.
What Are Restricted and Control Securities?
The SEC’s investor publication on Rule 144 draws the distinction clearly, and it is worth getting right because the two categories carry different conditions.
Restricted securities are securities acquired in unregistered, private sales from the issuing company or from an affiliate of the issuer. The SEC lists the usual routes by which investors receive them: private placement offerings, Regulation D offerings, employee stock benefit plans, compensation for professional services, or in exchange for providing seed money or start-up capital to the company. Rule 144(a)(3) identifies which sales produce restricted securities.
Control securities are those held by an affiliate of the issuing company. The SEC defines an affiliate as a person, such as an executive officer, a director, or a large shareholder, in a relationship of control with the issuer, and defines control as the power to direct the management and policies of the company, whether through ownership of voting securities, by contract, or otherwise.
Two practical consequences follow that catch people out regularly.
- Buying from an affiliate transfers the restriction to you. The SEC states that if you buy securities from a controlling person or affiliate, you take restricted securities even if they were not restricted in the affiliate’s hands.
- Securities an affiliate buys in the open market are not restricted, but their resale is still constrained. Because securities acquired in the public market are not restricted, there is no holding period for an affiliate who purchases them in the marketplace, but the resale of an affiliate’s shares as control securities is still subject to the rule’s other conditions.
There is also a visible marker. The SEC notes that an investor who acquires restricted securities will almost always receive a certificate stamped with a restrictive legend indicating that the securities may not be resold in the marketplace unless registered with the SEC or exempt from registration. Certificates for control securities usually are not stamped with a legend.
What Are the Five Conditions of Rule 144?
The SEC summarises five conditions. An affiliate selling control or restricted securities generally has to satisfy all of the applicable ones.
| Condition | What it requires | Applies to |
|---|---|---|
| Holding period | At least six months if the issuer is a reporting company subject to Exchange Act reporting requirements, at least one year if it is not. The period begins when the securities were bought and fully paid for. | Restricted securities only |
| Current public information | Adequate current information about the issuing company must be publicly available before the sale. For reporting companies this generally means compliance with the periodic reporting requirements of the Securities Exchange Act of 1934. For non-reporting companies it means certain company information is publicly available, including the nature of its business, the identity of its officers and directors, and its financial statements. | Affiliates, and non-affiliates in the six to twelve month window for reporting companies |
| Trading volume formula | The number of equity securities sold during any three-month period cannot exceed the greater of 1 percent of the outstanding shares of the same class, or, if the class is listed on a stock exchange, the greater of 1 percent or the average reported weekly trading volume during the four weeks preceding the filing of a notice of sale on Form 144. | Affiliates |
| Ordinary brokerage transactions | Sales must be handled in all respects as routine trading transactions, brokers may not receive more than a normal commission, and neither the seller nor the broker can solicit orders to buy the securities. | Affiliates |
| Filing a notice of proposed sale | A notice on Form 144 must be filed with the SEC if the sale involves more than 5,000 shares or the aggregate dollar amount is greater than 50,000 dollars in any three-month period. | Affiliates |
Several tacking rules attach to the holding period and are worth knowing because they change the start date:
- Additional securities purchased from the issuer do not affect the holding period of previously purchased securities of the same class.
- Restricted securities purchased from another non-affiliate allow the buyer to tack on that non-affiliate’s holding period.
- For gifts made by an affiliate, the holding period begins when the affiliate acquired the securities, not on the date of the gift.
- For a stock option, including an employee stock option, the holding period begins on the date the option is exercised, not the date it was granted.
That last point is the one that most often surprises employees at newly public or recently acquired companies. Years of vesting do not start the clock. Exercise does.
What Changes If You Are Not an Affiliate?
The conditions relax substantially, and the SEC states the two cases directly.
If you are not, and have not been for at least three months, an affiliate of the company issuing the securities, and you have held the restricted securities for at least one year, you can sell the securities without regard to the conditions described above. If the issuer is subject to Exchange Act reporting requirements and you have held the securities for at least six months but less than one year, you may sell as long as you satisfy the current public information condition.
| Seller | Issuer | Holding period elapsed | Conditions that apply |
|---|---|---|---|
| Affiliate | Reporting company | Six months or more | Current public information, volume formula, ordinary brokerage transactions, and Form 144 notice above the thresholds |
| Affiliate | Non-reporting company | One year or more | The same set, with current public information met through the alternative disclosures |
| Affiliate, shares bought in the open market | Any | No holding period applies | The rule’s other conditions still apply to resale of control securities |
| Non-affiliate for at least three months | Reporting company | Six months to one year | Current public information only |
| Non-affiliate for at least three months | Reporting company | One year or more | None of the conditions above |
| Non-affiliate for at least three months | Non-reporting company | One year or more | None of the conditions above |
The three-month look-back on affiliate status is easy to miss and does real work. Someone who resigned from a board last month is still treated as an affiliate for this purpose. The status question is about the past three months, not about the present moment.
Worked Example: How the Volume Formula Binds
Both companies below are hypothetical and were constructed for this guide to show how differently the same formula behaves depending on liquidity. In each case the seller is an affiliate holding 400,000 restricted shares of a reporting company, acquired in a private placement eight months earlier, so the six-month holding period is satisfied.
| Input | Company A, exchange listed and liquid | Company B, exchange listed and thin |
|---|---|---|
| Shares outstanding | 60,000,000 | 8,000,000 |
| 1 percent of shares outstanding | 600,000 | 80,000 |
| Average reported weekly volume, four weeks preceding the filing | 900,000 | 20,000 |
| Applicable limit, greater of the two | 900,000 shares per three months | 80,000 shares per three months |
| Shares the affiliate wishes to sell | 400,000 | 400,000 |
| Can the position be sold in one three-month period? | Yes, 400,000 is below the 900,000 limit | No |
| Minimum number of three-month periods required | 1 | 5, since 400,000 divided by 80,000 is 5 |
| Approximate elapsed time to exit fully | Within one quarter | About 15 months |
| Is a Form 144 required? | Yes, the sale involves more than 5,000 shares | Yes, each tranche exceeds 5,000 shares |
Every figure was computed for these illustrations from the stated inputs and can be reproduced from the table. The point is not the specific arithmetic but the asymmetry it produces: an identical position, identical holding period, and identical intention produce a one-quarter exit at one company and a multi-year exit at another. The variable that decides it is trading volume, which the seller does not control.
The SEC also notes a further tightening for securities that are not exchange listed: over-the-counter stocks, including those quoted on the OTC Bulletin Board and the Pink Sheets, can only be sold using the 1 percent measurement. For a thinly traded over-the-counter issuer, the average weekly volume alternative is simply unavailable, so the 1 percent figure is the ceiling regardless of how actively the stock happens to trade.
This is also why a cluster of Form 144 filings from one affiliate over consecutive quarters is often a mechanical consequence of the volume limit rather than an escalating signal. A large holder unwinding a position in a constrained security has no alternative but to file repeatedly.
Form 144 Versus Form 4: What Each One Tells You
These two filings are frequently confused, and the confusion produces bad inferences in both directions.
| Feature | Form 144 | Form 4 |
|---|---|---|
| What it is | Notice of a proposed sale under Rule 144 | Statement of changes in beneficial ownership |
| Timing | Filed before the sale | Filed after the transaction |
| Who files | An affiliate selling under Rule 144 above the thresholds | Section 16 insiders: officers, directors, and beneficial owners of more than 10 percent of a registered class |
| Does it confirm a trade? | No. It states an intention. | Yes. It reports what happened. |
| Price | Not an executed price | Reported execution price or price range |
| Trigger | More than 5,000 shares, or an aggregate dollar amount greater than 50,000 dollars in any three-month period | A reportable change in beneficial ownership |
| Best use in research | Advance visibility into planned affiliate selling capacity | Confirmation of actual insider buying and selling |
The correct reading discipline follows from the table. Treat a Form 144 as a statement of intent that may or may not be acted on, then look for a corresponding Form 4 to learn whether, when, and at what price the sale actually occurred. A Form 144 filed with no subsequent Form 4 from a Section 16 insider is a plan that was not executed, at least not in the period covered.
For the reporting side of the pair, see SEC Forms 3, 4, and 5 explained and how to read a Form 4 on EDGAR. The transaction codes that distinguish an open-market sale from an option exercise or a tax withholding are covered in Form 4 transaction codes.
Where Rule 10b5-1 Plans Fit
Many affiliate sales are executed under a written trading arrangement adopted in advance, so that the individual is not making trading decisions while aware of material non-public information. That arrangement and Rule 144 are complementary rather than alternatives, and both can apply to the same sale.
- The trading arrangement addresses when and how decisions are made. It is designed so that the specific trades are determined ahead of time rather than at the moment of execution.
- Rule 144 addresses whether the resale itself is exempt from registration. It is about the securities and the seller’s relationship to the issuer, not about information.
- The volume limit and the Form 144 notice still apply. A sale executed under a pre-adopted plan by an affiliate remains subject to the three-month volume ceiling and to the notice threshold.
This is the main reason a run of Form 144 filings can look like a coordinated exit and be nothing of the sort. Scheduled sales under an arrangement adopted months earlier produce regular, evenly sized filings, which is close to the opposite of a discretionary decision to sell. The mechanics of those arrangements are covered in Rule 10b5-1 trading plans, and the broader interpretation problem in interpreting insider selling.
Removing a Restrictive Legend
Satisfying Rule 144 is necessary but not sufficient. The SEC is explicit: even if you have met the conditions of Rule 144, you cannot sell your restricted securities to the public until you have had the legend removed from the certificate.
The process has a specific chain of control:
- Only a transfer agent can remove a restrictive legend.
- The transfer agent will not remove it without the issuer’s consent, usually in the form of an opinion letter from the issuer’s counsel stating that the legend can be removed.
- Without that consent the transfer agent has no authority to remove the legend or to permit execution of the trade in the marketplace.
- To begin the process, the holder contacts the issuing company or the transfer agent to ask about their procedures.
The SEC also describes what happens when the parties disagree. If a dispute arises about whether a restrictive legend can be removed, the SEC will not intervene. Removal of a legend is a matter solely in the discretion of the issuer of the securities, state law rather than federal law covers disputes about removal, and the SEC will not take action in any decision or dispute about removing a restrictive legend.
That is a meaningful practical risk for a holder of restricted stock. The right to sell under Rule 144 and the ability to sell are separate things, and the second one depends on cooperation from the company. The SEC notes that removing the legend can be a complicated process requiring work with an attorney who specialises in securities law.
Finding and Reading Form 144 Filings
Form 144 filings are available through SEC EDGAR alongside the issuer’s other filings. The SEC adopted amendments in 2022, in a release titled Updating EDGAR Filing Requirements and Form 144 Filings (Release Nos. 33-11070 and 34-95025, issued 2 June 2022), that mandate electronic filing or submission on EDGAR of a range of documents that were previously permitted rather than required to be filed electronically, including notices of sales of securities of certain issuers.
When you open one, read these fields in this order:
- The issuer and the class of securities. A company can have multiple classes with very different share counts, and the 1 percent test applies to the class being sold.
- The number of shares to be sold and the approximate date of sale. Both are proposed, not executed.
- The aggregate market value stated. This is an estimate at the time of filing, not a realised amount.
- Shares outstanding for the class. This lets you compute the 1 percent figure and see how close the proposed sale sits to the ceiling.
- The nature of the acquisition and the acquisition date. This is what establishes the holding period and tells you whether the shares came from an option exercise, a grant, or a private purchase.
- Securities sold during the past three months. This is the running total against the volume limit, and it is the field that shows whether the seller is at capacity.
Then look for the follow-up. If the filer is a Section 16 insider, a Form 4 should appear after any actual sale. That is the document that turns an intention into a fact.
Misconceptions Versus Reality
| Misconception | Reality |
|---|---|
| A Form 144 means an insider sold stock | It means an affiliate gave notice of an intended sale. Confirmation comes from a Form 4, if the filer is a Section 16 insider. |
| Repeated Form 144 filings show escalating pessimism | They frequently show a large holder working within the three-month volume ceiling, which requires repeated filings by construction. |
| Rule 144 is the only way to sell restricted stock | The SEC describes it as a safe harbour and states explicitly that it is not the exclusive means for selling restricted or control securities. |
| The holding period starts when the shares were granted or when they vested | It begins when the securities were bought and fully paid for. For options, including employee stock options, it begins on the date the option is exercised. |
| Shares an affiliate bought on the open market are unrestricted and freely sellable | They are not restricted securities and carry no holding period, but their resale as control securities remains subject to the rule’s other conditions. |
| Meeting Rule 144 means the shares are tradable | The restrictive legend must still be removed, which requires the issuer’s consent and the transfer agent’s action. |
| Every restricted holder has to file a Form 144 | The notice obligation described applies to affiliates, and only above the 5,000 share or 50,000 dollar thresholds in a three-month period. |
| The dollar figure on the form is the money the seller received | It is an aggregate market value stated at the time of the notice, before any sale has occurred. |
How to Use Form 144 Data Without Overreading It
Form 144 belongs in the ownership data set, but it belongs there as a capacity and intention signal rather than as evidence of a decision. Every structural feature of the filing points that way. It is filed in advance, so it describes a plan. It is triggered by thresholds as low as 5,000 shares or 50,000 dollars over three months, so it captures routine sales as readily as significant ones. It states an aggregate market value estimated at the moment of filing, so its dollar figure is not proceeds. And it is filed because a volume ceiling forces a large position to be unwound in instalments, so its frequency reflects the size of the holding and the liquidity of the stock at least as much as it reflects any view about the company.
What the filing genuinely tells you is more useful than what people usually try to read into it. It tells you who is an affiliate, which is not always obvious from the Section 16 filings alone. It tells you how the shares were acquired and when, which establishes whether you are looking at a founder’s original stake, a private placement from a financing round, or an exercised option. It tells you how much of the three-month volume allowance has already been used, which is the field that shows whether a seller is working at capacity. And, read across several quarters, it maps the shape of a planned exit: steady equal tranches look like a pre-arranged schedule, while irregular filings that begin abruptly look like something else.
The discipline that keeps all of this honest is pairing. Read the Form 144 for the plan and the Form 4 for the execution, and treat the gap between them as information in its own right. A notice with no subsequent Form 4 is a sale that did not happen in that window. A Form 4 at a materially different size from the notice tells you the plan changed. Neither of those observations is available from either filing on its own, which is precisely why the pair is worth reading together and why a screen built on Form 144 headlines alone produces so many false signals.

Frequently Asked Questions
What is SEC Form 144?
Form 144 is a notice of proposed sale filed with the SEC by an affiliate who intends to sell restricted or control securities under Rule 144. The SEC states that an affiliate must file a notice on Form 144 if the sale involves more than 5,000 shares or the aggregate dollar amount is greater than 50,000 dollars in any three-month period. It announces an intention to sell rather than reporting a completed transaction.
Does a Form 144 filing mean an insider actually sold shares?
No. Form 144 is filed before a proposed sale, so it records an intention rather than an execution. To learn whether a sale actually occurred, at what size and at what price, look for a Form 4 from the same person afterwards, since Section 16 insiders report completed transactions there. A Form 144 with no matching Form 4 indicates the planned sale did not take place in that period.
What are restricted securities?
Restricted securities are securities acquired in unregistered, private sales from the issuing company or from an affiliate of the issuer. The SEC lists the common routes as private placement offerings, Regulation D offerings, employee stock benefit plans, compensation for professional services, and exchanges for seed money or start-up capital. Rule 144(a)(3) identifies which sales produce restricted securities.
What is the Rule 144 holding period?
Six months if the issuing company is a reporting company subject to the reporting requirements of the Securities Exchange Act of 1934, and one year if the issuer is not subject to those requirements. The period begins when the securities were bought and fully paid for. It applies only to restricted securities, so an affiliate who purchased shares in the open market has no holding period for those shares.
How much stock can an affiliate sell under Rule 144?
The SEC describes the trading volume formula as follows: the number of equity securities an affiliate may sell during any three-month period cannot exceed the greater of 1 percent of the outstanding shares of the same class being sold, or, if the class is listed on a stock exchange, the greater of 1 percent or the average reported weekly trading volume during the four weeks preceding the filing of a notice of sale on Form 144.
Is the volume limit different for over-the-counter stocks?
Yes, and it is tighter. The SEC states that over-the-counter stocks, including those quoted on the OTC Bulletin Board and the Pink Sheets, can only be sold using the 1 percent measurement. The average reported weekly trading volume alternative is unavailable for those securities, so 1 percent of the outstanding shares of the class is the ceiling for any three-month period.
What conditions apply if I am not an affiliate?
If you are not, and have not been for at least three months, an affiliate of the issuing company, and you have held the restricted securities for at least one year, you can sell without regard to the Rule 144 conditions. If the issuer is subject to Exchange Act reporting requirements and you have held for at least six months but less than one year, you may sell provided the current public information condition is satisfied.
What is the difference between Form 144 and Form 4?
Form 144 is filed by an affiliate before a proposed sale of restricted or control securities and states an intention. Form 4 is filed by a Section 16 insider after a transaction and reports a completed change in beneficial ownership, including the execution price. One looks forward and may not result in any trade; the other looks backward and confirms what happened.
When does the holding period start for stock options?
On the date the option is exercised, not the date it was granted. The SEC states this explicitly for stock options including employee stock options. Vesting does not start the clock either. This regularly surprises employees who have held options for years and assume the shares are immediately saleable once they exercise.
Can I remove a restrictive legend myself once Rule 144 is satisfied?
No. Only a transfer agent can remove a restrictive legend, and the transfer agent will not do so without the issuer’s consent, usually in the form of an opinion letter from the issuer’s counsel. Without that consent the transfer agent has no authority to remove the legend or to permit the trade. The SEC notes that the process can be complicated and may require a securities attorney.
What happens if the company refuses to remove the legend?
The SEC will not intervene. It states that removal of a legend is a matter solely in the discretion of the issuer of the securities, that state law rather than federal law covers disputes about removing legends, and that it will not take action in any decision or dispute about removing a restrictive legend. The holder’s recourse is therefore through state law rather than through the Commission.
Where can I find Form 144 filings?
Through SEC EDGAR, alongside the issuer’s other filings. The SEC adopted amendments in June 2022, in Release Nos. 33-11070 and 34-95025 titled Updating EDGAR Filing Requirements and Form 144 Filings, mandating electronic filing or submission on EDGAR for a range of documents that had previously been permitted rather than required to be filed electronically, including notices of sales of securities of certain issuers.
