Shelly Brown, Executive Vice President and Chief Strategy Officer at Miami International Holdings, sold 3,257 shares across two trades on April 6-7, 2026 under a pre-arranged 10b5-1 plan for roughly $135,214. The transactions occurred as MIAX traded above InvestingPro's Fair Value estimate. The company reported robust fourth-quarter 2025 results and higher year-to-date trading volumes through March 2026, while remaining unprofitable over the prior twelve months despite analyst expectations of a return to profitability this year.

Key Points

  • Shelly Brown sold 3,257 MIAX shares on April 6-7, 2026 under a pre-arranged 10b5-1 plan for approximately $135,214; she now holds 324,147 shares - financial services and capital markets sectors.
  • Miami International Holdings reported Q4 2025 EPS of $0.52 versus analysts' $0.33 and revenue of $125 million, a 52% year-over-year increase - corporate earnings and exchange operator performance.
  • MIAX Exchange Group volumes rose, with year-to-date average daily trading volume up 26.6% to 10.9 million contracts through March 2026 and February 2026 average daily volume up 25.4% year-over-year to 10.8 million contracts, capturing 17.1% of the U.S. equity options market - market share and trading activity.

Shelly Brown, who serves as Executive Vice President and Chief Strategy Officer at Miami International Holdings, INC. (MIAX:MIAX), executed two stock sales under a pre-arranged 10b5-1 trading plan on April 6 and April 7, 2026. The total disposal amounted to 3,257 shares of common stock for an aggregate consideration of approximately $135,214.

The first sale, on April 6, comprised 2,357 shares sold at a weighted average price of $41.33 per share. Trade prices within that lot ranged from $40.10 to $41.79. The second sale, completed on April 7, consisted of 900 shares transacted at $42.00 per share.

Following the two transactions, Brown retains direct ownership of 324,147 shares of Miami International Holdings. The company is identified in market data as having a market capitalization of $3.83 billion.


Market context noted alongside the disclosure indicates MIAX was trading above InvestingPro's Fair Value estimate at the time of the sales. The same InvestingPro notes highlight that Miami International Holdings has not been profitable over the last twelve months, though analysts included in InvestingPro data project the company will achieve profitability within the current year.

Financial results released for the fourth quarter of 2025 show a meaningful improvement in the company’s operating performance. Miami International Holdings reported earnings per share of $0.52 for the quarter, compared with analysts' consensus of $0.33. Quarterly revenue came in at $125 million, representing a 52% increase relative to the same quarter one year earlier.

Operational volumes at the MIAX Exchange Group also strengthened. Year-to-date average daily trading volume rose 26.6% to 10.9 million contracts through March 2026. For February 2026 specifically, the group reported an average daily volume of 10.8 million contracts, a 25.4% increase compared with February 2025. The group’s reported market share for U.S. equity options stood at 17.1% for the period referenced.

Governance activity during the same period included a change to the board of directors: Lee Becker informed the company that he will not stand for reelection at the 2026 Annual Meeting of Shareholders. The company stated that Becker’s decision is not the result of any disagreement with management or the board.


These disclosures combine insider selling activity, valuation context from InvestingPro, recent quarterly earnings and revenue growth, volume trends at the MIAX Exchange Group, and a board-level departure. Together they provide a multi-faceted view of recent developments at Miami International Holdings but do not, on their own, establish causation between the insider sale and broader company performance.

The facts above are limited to the transactions and corporate results that were reported. Where commentary or forward-looking projection is referenced it reflects the InvestingPro notes cited alongside the transaction disclosure.

Risks

  • Valuation concern: MIAX was trading above InvestingPro's Fair Value estimate at the time of the insider sales, which may indicate potential overvaluation - affects investor sentiment in financial services and equities.
  • Profitability uncertainty: The company was not profitable over the last twelve months, creating execution risk until analysts' projected return to profitability is realized - impacts earnings expectations for exchange operators.
  • Board-level change: A director, Lee Becker, will not stand for reelection at the 2026 Annual Meeting; while the departure is not attributed to disagreements, it introduces a governance change that could affect stakeholder perceptions - relevant to corporate governance in the financial sector.
