Miami International Holdings Launches Secondary Public Offering

On December 9, 2025, Miami International Holdings, Inc., known by the stock symbol MIAX, announced a significant step in its financial operations by launching a proposed secondary public offering of 6,750,000 shares of its common stock. This move is primarily aimed at allowing certain selling stockholders to divest their holdings, thereby providing an opportunity for new investors to become part of the MIAX family.

Details of the Offering

The proposed secondary public offering encompasses shares that are being sold entirely by current stockholders. Notably, MIAX itself will not be selling any shares in this offering, which means the company will not see any proceeds from the sale. This indicates that the offering is primarily oriented toward facilitating liquidity for existing investors rather than raising new capital for the business.

The offering also includes a provision for underwriters to purchase up to an additional 1,012,500 shares within a 30-day window, which can serve to enhance market stability should demand exceed expectations.

Underwriters and Management

In orchestrating this offering, Miami International has engaged prominent financial institutions as lead joint bookrunning managers, including J.P. Morgan, Morgan Stanley, and Piper Sandler. These firms are known for their expertise in managing public offerings, thereby ensuring that the process is handled with proficiency and investor confidence.

Other notable organizations participating as joint bookrunning managers include Raymond James, Rosenblatt, William Blair, and Keefe, Bruyette & Woods, a Stifel Company. Their collective experience is expected to guide the offering effectively, setting the stage for a successful transaction.

Accessing the Prospectus

The formal details of the offering will be available through a prospectus, which can be accessed for free via the U.S. Securities and Exchange Commission's EDGAR database. Those interested in obtaining a copy will find it available from various financial institutions, including J.P. Morgan, Morgan Stanley, and Piper Sandler. This transparency is a critical component in public offerings, providing potential investors with the information needed to make informed decisions.

SEC Filing Status

It is important to note that a registration statement on Form S-1 concerning the shares has been filed with the SEC, but it has not yet been approved. Thus, the company emphasizes that no sales of common stock can occur until this registration statement becomes effective. This regulatory compliance underlines MIAX's commitment to transparency and investor protection.
