What Is Rule 144? Definition, How It Works and Examples

In finance, Rule 144 is the standard route for selling shares that never went through a public offering. The SEC, the US securities regulator, wrote it under the Securities Act of 1933. It covers two kinds of shares. The first is restricted securities, shares that came from the company in a private deal. The second is control securities, shares of any kind held by an affiliate.

An affiliate is a person who controls the company, is controlled by it or shares common control with it. In practice that means directors, senior officers and large shareholders. The SEC describes control as the power to direct the company’s management and policies, through votes, a contract or otherwise.

The rule matters because the law treats every sale of securities as needing registration unless an exemption applies. Ordinary investors trading on an exchange use an exemption without thinking about it. A holder of private shares has to show that the exemption fits. Rule 144 gives a checklist for doing that.

Under the Securities Act, a person who buys shares from a company in order to resell them to the public is an underwriter. An underwriter’s sale needs registration. Rule 144 says that a seller who meets its conditions is deemed not to be an underwriter. That is why lawyers call it a safe harbor: if you stay inside it, the sale is exempt.

So the Rule 144 securities question is really two questions. Are your shares restricted, because they came from the company privately? And are you an affiliate, so that even shares you bought on the market count as control securities? The answers decide which conditions apply to you.

Non-affiliate, company reports

Hold for six months. Until one year has passed, the company must also have current public information. After one year, the holding period is the only condition.

Non-affiliate, company does not report

Hold for one year. No other Rule 144 condition applies to the sale.

Affiliate

Every condition applies: current public information, the holding period for restricted shares, the volume cap, the manner of sale and the Form 144 notice above the size test.

Status is checked at the time of sale and over the three months before it. A former officer who left the company less than three months ago still counts as an affiliate for this test.

Rule 144 restricted stock is stock you received from the company, or from an affiliate, in a deal that was not a public offering. The rule lists the main sources. They include a private placement under Regulation D, shares employees receive under Rule 701, and resales to large institutions under Rule 144A. Most shares in a private company fall into one of these groups.

Restricted stock usually carries a legend. That is a printed or electronic note on the share record saying the shares may not be resold unless they are registered or exempt. Control securities usually carry no legend, but the affiliate rules still apply to them.

How the Legend Comes Off

Meeting the holding period does not change the share record by itself. Only the transfer agent, the firm that keeps the company’s register of shareholders, can remove the legend. The SEC says the agent will not act without the company’s consent. That consent usually comes as an opinion letter from the company’s lawyers. The SEC’s guide to Rule 144 warns that the process can be complicated.

The table sums up the conditions and where each one sits in the rule. Non-affiliates deal mainly with the first three rows. Affiliates deal with all of them.

The notice an affiliate files before selling has its own page: Form 144. Many insiders also sell through a Rule 10b5-1 plan, a trading schedule set up in advance. The plan does not replace Rule 144. The sales under it still have to meet the conditions above.

The Rule 144 date is the day your holding period ends and the shares become eligible for sale under the rule. The clock starts when you bought the shares and paid for them in full. Some later events keep the original start date. A stock split, a stock dividend and a conversion of preferred stock into common all carry the earlier date forward.

Stock options work differently. An employee option is acquired without cash or investment risk, so the clock starts when you exercise it and pay. A cashless exercise, where some of the shares pay for the rest, keeps the date of the option grant. For equity granted to staff, Rule 701 adds a shortcut covered below.

The pattern in the table is common. For most early holders, the Rule 144 date arrives before the lock-up ends. The holding period sets the earliest legal date. The contract and the company’s policies usually set the real one.

While the company is private, its shares have no public market. Holders sell, if at all, through secondary transactions or a company tender offer. These deals often rely on other exemptions and need the company’s approval under its own transfer rules. Rule 144 sets the legal floor, and the company’s documents can add more.

After an IPO, three dates line up. The IPO lock-up ends, typically after 180 days. The Rule 144 holding period has usually passed for early holders. Shares granted to employees under Rule 701 become sellable for non-affiliates 90 days after the company starts reporting. Whatever comes last is the day you can sell. The page on lock-up expiration covers what that day can do to the stock price.

If you hold through a fund or an SPV, a special purpose vehicle that pools investors’ money for one deal, the vehicle is the shareholder. Rule 144 applies to its sale, and its manager decides when to sell.

• Starting the clock at the option grantFor a cash exercise, the holding period starts when you exercise and pay. The grant date counts only in a cashless exercise.
• Treating the Rule 144 date as the sale dateA lock-up or the company’s transfer rules can keep you from selling long after the holding period ends.
• Forgetting the legendAn eligible share with a legend on it still cannot be sold on the market. The transfer agent removes it after the company consents.
• Ignoring affiliate statusA director’s shares bought on the exchange are control securities. The volume cap and notice rules apply to them.
• Assuming a promissory note starts the clockPaying with a note counts only if it has full recourse, adequate collateral and is paid off before the sale.
• Mixing up Rule 144 and Rule 144ARule 144 governs resales to the public. Rule 144A governs resales to large institutions known as qualified institutional buyers.

Figures were last checked on October 21, 2026. The rules are United States federal rules. Company documents and lock-up contracts can add limits of their own, so check them before you plan a sale.
