Miami International Holdings Unveils Plans for Secondary Stock Offering
On December 9, 2025, Miami International Holdings, Inc. (commonly referred to as MIAX), which is listed on the New York Stock Exchange under the ticker MIAX, revealed its intention to conduct a secondary public offering. This offering includes a total of 6,750,000 shares of its common stock, which comprises shares granted through warrants to certain key stockholders of the company.
The significant aspect of this offering is that it consists solely of secondary shares owned by existing stockholders known as the Selling Stockholders, meaning that MIAX will not sell any of its own common stock nor will the company receive any financial benefits from the proceeds of this sale. Additionally, the underwriting team, which consists of Joseph, Morgan Stanley, and Piper Sandler, has been entrusted with managing this offering as joint lead bookrunning managers.
As part of the offering mechanism, the underwriters have a provision allowing them to purchase an extra 1,012,500 shares within a 30-day option period from the Selling Stockholders. This additional option provides flexibility and potential further capital fluidity in the wake of increased demand.
To participate and understand more about the offering, interested parties must refer to a prospectus that outlines the details of the offering, which will be accessible through EDGAR on the U.S. Securities and Exchange Commission’s (SEC) website. It is essential to note that until the registration statement on Form S-1, pertaining to MIAX's common stock, becomes effective, no shares may be sold or offers to buy can be accepted. Furthermore, this release does not serve as an offer to sell or solicit offers to buy shares in any jurisdiction where such activities would require registration or qualification under regional securities laws.
MIAX is recognized as a leader in operating regulated financial markets across diversified asset classes and geographical regions. Currently, it manages nine exchanges that span options, futures, equities, and international markets. This notably includes MIAX Options, MIAX Pearl, MIAX Emerald, and MIAX Sapphire, among others. Moreover, MIAX owns Dorman Trading, which is a fully-fledged Futures Commission Merchant.
Potential investors are advised to keep a watch on the official communications from MIAX and the financial institutions involved to ensure they are informed about the exact timelines and procedures for engaging with this stock offering. As part of a broader strategy, this initiative aligns with MIAX's steadfast commitment to enhancing liquidity and operational efficiency within financial markets while focusing on shareholder value.
Finally, the issuing of shares by existing shareholders can be seen as a reflection of their trust in Miami International Holdings' potential and forecasted growth in an evolving market landscape. As MIAX continues to innovate and expand its influence within the financial services sector, stakeholders should stay tuned for any updates regarding the offering as more details become available and as shares navigate through market dynamics. Investors are reminded to consult with financial advisors before participating in any stock transactions, particularly in light of the inherent risks noted in this release that relate to forward-looking statements regarding the future performance and strategic endeavors of MIAX.
