Tertiary Market

The tertiary market is the market for securities subject to resale restrictions. Most commonly, it involves sales of restricted stock by company insiders — founders, executives, employees, and early investors — whose shares are subject to a lockup period or transfer restrictions. Tertiary market transactions require SEC registration exemptions (typically Rule 144) and typically involve a smaller pool of institutional buyers.

The nature of restricted securities

When a company goes public via initial public offering, not all shareholders receive unrestricted public shares. Insiders, early investors, and certain employees hold restricted shares subject to a lockup period, typically lasting 180 days (six months). During this period, they cannot sell; the SEC treats these shares as unregistered securities.

After the lockup period expires, insiders can sell under Rule 144 of the Securities Act, which allows certain holders of restricted securities to sell without registering the shares, provided they meet strict volume and holding-period requirements. Rule 144 has complex conditions: the seller must have held the shares for at least six months (one year in some cases), and sales are limited to the greater of 1% of outstanding shares or the average weekly trading volume of the preceding four weeks.

The tertiary market exists in the gaps left by lockup periods and Rule 144 limitations. It allows insiders to begin selling shares, albeit in a controlled way, before they can dump unrestricted quantities into the secondary market.

How tertiary trades work

A tertiary market transaction typically involves an insider, a broker-dealer specializing in restricted securities, and an institutional buyer — a hedge fund, insurance company, or dedicated restricted securities fund. The process is opaque and negotiated one-deal-at-a-time.

The insider or their advisor approaches a broker-dealer and describes the quantity and terms of shares to be sold. The broker-dealer canvasses institutional clients to gauge interest. Negotiations focus on price, volume, and timing. Tertiary market prices are typically 5–15% discounted to the public secondary market price, reflecting the illiquidity and restrictions on resale.

Documentation is careful. The buyer and seller enter a purchase agreement that specifies the number of shares, price, closing date, and representations and warranties. An escrow agent may hold the shares until all conditions are met. Legal counsel from both sides reviews the transaction to ensure it complies with Rule 144, company insider trading policies, and securities law.

Once the deal closes, the buyer receives share certificates or book-entry shares marked as restricted. The buyer must then hold these shares in compliance with Rule 144 before being able to sell them freely on the secondary market. This means a tertiary buyer is not purchasing liquidity; they are purchasing a restricted security with a future path to liquidity.

The lockup period and its mechanics

Immediately after an IPO, the company’s underwriters impose a lockup period during which insiders cannot sell. This lock-up is typically agreed to with the underwriters as part of the IPO process. It serves several purposes:

• It prevents a flood of insider sales immediately after the IPO, which would depress the stock price and signal that insiders lack confidence in the company.
• It preserves the IPO syndicate’s trading power; if insiders are restrained, the underwriters retain their customers longer.
• It allows the market to absorb shares gradually, without the supply shock that would result if all founders and employees immediately began selling.

Lockup periods are typically 180 days. When the lockup expires, insiders are free to sell under Rule 144 restrictions. This expiration date is known as “lockup-expiration day,” and it can be a volatile moment; some insiders sell substantial quantities at the moment the lock expires, moving the price.

Buyer motivations

Tertiary market buyers are not bargain-hunting speculators. They are typically sophisticated institutions with specific motivations:

Liquidity provision. Some hedge funds and trading firms profit by buying restricted securities at a discount and selling them months later on the public market, earning the spread.

Long-term conviction. Some institutional buyers believe in the company and prefer to acquire shares at a discount to the public price. They are willing to accept restriction because they plan to hold for years.

Insider alignment. A buyer might want to own a large stake and may negotiate with the insider seller to take a meaningful position, further aligning incentives.

Portfolio construction. A fund seeking exposure to a company might find a tertiary buyer beneficial because it allows them to build a position over time without moving the public market price.

Regulatory oversight

Tertiary trading is not formally regulated as a separate market; it falls under the SEC’s Rule 144 exemptions and securities law. The SEC monitors tertiary deals to ensure they comply with volume and timing rules and that sellers are not circumventing registration requirements.

Insiders must also comply with the company’s insider trading policies, which often impose additional restrictions beyond Rule 144. Executives and board members may be prohibited from trading during blackout periods surrounding earnings announcements or material events.

Transactions that appear unusual — large sales by a single insider, or coordinated sales by multiple insiders — can trigger SEC scrutiny for insider trading violations. Insiders are also required to file Form 4 with the SEC within two business days of a sale, disclosing the quantity, price, and nature of the transaction.

Tertiary vs. secondary vs. primary markets

The tertiary market occupies an intermediate position. The primary market is where the company first issues equity and receives cash. The secondary market is where unrestricted shares trade continuously, with price discovery driven by broad supply and demand. The tertiary market allows restricted shares to begin circulating before they become unrestricted, at a discount that reflects their restricted status.

As lockup periods expire and Rule 144 limitations ease, shares migrate from the tertiary market into the secondary market. This transition is typically smooth if demand is strong, but lockup expiration can be disruptive if insiders perceive the stock as overvalued and sell aggressively.

Pricing and discount dynamics

The tertiary market discount reflects the value of the option embedded in a restricted share. The buyer is acquiring illiquidity for a period and accepting the risk that the public price could fall during that period. Discounts vary based on:

• The amount of time remaining until the share becomes fully unrestricted; shorter times command smaller discounts.
• Trading volume of the public share; higher volume means faster eventual resale, justifying a smaller discount.
• Volatility of the stock price; higher volatility increases the buyer’s risk, commanding a larger discount.
• Market sentiment; in a bull market, tertiary buyers are eager and discounts compress; in a bear market, discounts widen.

A tertiary buyer purchasing shares at a 10% discount expects to sell them in the secondary market at parity within a year or two and earn the 10% return.
