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

In finance, Rule 144A is a resale rule. US law says a sale of stocks or bonds must be registered with the SEC unless an exemption applies. A company can sell in private under the private placement exemption. But a buyer who sells on too soon could be seen as an underwriter, someone who buys in order to distribute the securities. Then the resale needs registration too.

Rule 144A takes away that doubt for one kind of buyer. If the stocks or bonds go only to a qualified institutional buyer (QIB), the seller is not treated as part of a distribution. The same holds for a dealer who sells this way. The buyer still holds restricted securities, so the next sale needs an exemption as well.

The market is large. In 2024, companies raised about $1T through Rule 144A and Regulation S deals, the SEC staff says. Regulation S covers sales made outside the US. For 2012, the SEC put Rule 144A deals by operating companies at $636B. Registered deals raised $1.2T that year.

A Rule 144A deal uses two exemptions. The company uses one to sell, and the banks use Rule 144A to sell on. The steps run like this.

1. 01
   The private saleThe company sells new securities to one or more banks, called initial purchasers. That sale relies on the private offering exemption or on Regulation S.
2. 02
   The marketingThe banks offer the securities. Since September 23, 2013, they may offer them to anyone, even by public advertising, as long as they sell only to QIBs.
3. 03
   The resaleThe banks resell to buyers they reasonably believe are QIBs, and tell them that the sale relies on Rule 144A.
4. 04
   Later tradingQIBs can trade the securities among themselves under the same rule. A sale to anyone else needs another exemption.

Rule 144A works for US and foreign companies alike. When the SEC wrote it, one aim was to bring foreign deals into the US private market. A foreign company can then raise money from US funds without a full SEC filing.

Every Rule 144A resale must meet four conditions. The table gives each in plain terms.

The listed-class test explains what the rule is used for. Common shares of a listed company already trade on an exchange, so they cannot be sold under Rule 144A. Bonds and shares of private companies usually pass this test.

The names are close, but the rules do different jobs. Rule 144 lets holders sell restricted securities into the public market after a holding period. Rule 144A lets them sell to QIBs at any time.

Both examples are illustrative. The companies, buyers and amounts are invented to show how the conditions apply.

A $500 Million Bond Deal

A company sells $500M of new bonds to three banks in a private sale. The same day, the banks resell them to 40 insurers, pension plans and funds. Each buyer has confirmed it holds at least $100M in securities. Six months later, one insurer sells $20M of the bonds to a mutual fund that is also a QIB. Both resales fall under Rule 144A. A wealthy individual who asks to buy $1M is turned away.

A $5 Million Sale of Private Shares

An early investor holds preferred shares in a private company and wants $5M of cash. An insurer that qualifies as a QIB offers to buy. The shares are not of a listed class, so they pass that test. The company does not report to the SEC, so the buyer must be able to get its basic financial statements on request. The company’s own transfer limits still apply, so the sale may need its consent. Our guide to secondaries covers how such sales are priced.

If you are an individual, you cannot buy in a Rule 144A deal. Your routes into private companies are Regulation D private placements and, for smaller companies, Regulation A+ offerings. You may still hold Rule 144A bonds through a fund.

If you hold shares in a private company, Rule 144A is one exit to know about. It reaches only large buyers, and you usually need the company’s help with the facts and its consent to the transfer. Employees with Rule 701 shares and other holders face the same conditions.

Common Mistakes

• Mixing up Rule 144 and Rule 144ARule 144 opens the public market after a holding period. Rule 144A opens only sales to QIBs.
• Thinking the company uses Rule 144A to sellThe rule covers resales. The company sells under another exemption, usually to banks.
• Assuming the securities become free to tradeRule 144A securities stay restricted in the buyer’s hands.
• Selling listed common sharesA class listed on a US exchange fails the listed-class test.
• Skipping the buyer checkThe seller must reasonably believe the buyer is a QIB, using recent information.
