Key Terms

Post-Effective Amendment, deregister, voluntary delisting, reverse stock split

4 terms

Post-Effective Amendment regulatory

"Post-Effective Amendment No. 3 to Form S-1"

A post-effective amendment is an official update to a securities registration document filed after that document has become effective with regulators; it corrects, adds or replaces information about the securities, the company, or an offering. Investors care because it keeps the legal record current and can change what is being sold or the rights attached to shares — like getting a revised product manual after a launch that may affect value or use.

deregister regulatory

"to deregister any and all securities"

Deregister is the act of removing a company’s securities from a public regulatory registry or ending their listing on a stock exchange; think of it like taking a car off public roads so it no longer needs public inspections. For investors, deregistration matters because it usually reduces required public disclosures, can make shares harder to buy or sell, and increases uncertainty about the company’s finances and governance due to lower transparency and liquidity.

voluntary delisting regulatory

"apply for the voluntary delisting of the Class A common stock"

Voluntary delisting is when a company chooses to remove its shares from a public stock exchange so they no longer trade on that market. For investors this matters because it can make shares harder to buy or sell, reduce public disclosure and price transparency, and often signals a shift in strategy such as going private or moving to a smaller trading venue—similar to a store closing its high‑street shop but continuing to sell by appointment.

reverse stock split financial

"one-for-four reverse stock split of the Class A common stock"

A reverse stock split reduces a company's number of outstanding shares while raising the price per share proportionally, so the total value of each investor's holding is unchanged; a 1-for-10 split turns 100 shares worth $1 each into 10 shares worth $10 each. Companies often do this to regain compliance with an exchange's minimum price rule or to attract investors who avoid very low-priced stocks.

Direct Digital Holdings, Inc., a Delaware corporation (the “Company”), is filing these post-effective amendments (these “Post-Effective Amendments”) to the following Registration Statements on Form S-1 (collectively, the “Registration Statements”), which have been previously filed with the Securities and Exchange Commission (the “Commission”), to deregister:

•Any and all securities, registered but unsold or otherwise unissued as of the date hereof under the Registration Statement on Form S-1 (File No. 333-261059), as amended, initially filed with the Commission on November 15, 2021, registering (i) 2,800,000 units, each unit consisting of one share of the Company’s Class A common stock and one warrant to purchase one share of the Company’s Class A common stock, (ii) an additional 420,000 shares of Class A common stock and warrants to purchase an additional 420,000 shares of Class A common stock available upon the exercise of the underwriters’ over-allotment option and (iii) 280,000 shares of Class A common stock issuable upon the exercise of unit purchase options held by the underwriters entitling the underwriters to purchase units consisting of one share of Class A common stock and one warrant to purchase one share of Class A common stock;
