Transaction details

Director Kurt M. Eckert of Miami International Holdings, Inc. (MIAX) completed a sale of 37,917 shares of common stock on March 19, 2026, producing total proceeds of $1,478,763. The sales were carried out at a weighted average price of $39 per share, with individual transaction prices spanning from $38.62 to $39.48.

On the same day, Eckert exercised stock options to acquire 12,917 shares of common stock at an exercise price of $12 per share, for a total exercise cost of $155,004.


Ownership and trading plan

After these transactions, Eckert directly holds 142,375 shares of Miami International Holdings. The disposition of shares was executed pursuant to a pre-established Rule 10b5-1 trading arrangement that the director adopted on December 18, 2025. The 10b5-1 plan detail indicates the sale followed an authorized schedule rather than an ad hoc decision.


Valuation and earnings context

Miami International Holdings has a market capitalization reported at $3.62 billion and is trading close to InvestingPro's Fair Value estimate, indicating the stock is regarded as fairly valued by that assessment. Over the trailing twelve months, the company recorded an earnings per share (EPS) of -$1.00, reflecting a recent period of unprofitability.

Analysts, however, are anticipating a marked rebound, projecting EPS of $1.68 per share for fiscal 2026. The article notes that these figures are two of seven InvestingPro Tips available for more in-depth analysis of MIAX's investment case.


Recent operating performance and market footprint

Miami International Holdings reported strong results for the fourth quarter of 2025, surpassing earnings expectations. The company posted an adjusted diluted EPS of $0.52, well above the expected $0.33. Quarterly revenue reached $125 million, representing a 52% increase year over year.

Market activity at MIAX also showed growth in early 2026. In February 2026, the company's U.S. options exchanges handled an average daily volume of 10.8 million contracts, a 25.4% rise compared with February 2025. The MIAX Exchange Group achieved a 17.1% share of the U.S. equity options market in February, an increase of 8.1% from the same month a year earlier.


What this means

The disclosed sale and concurrent option exercise update a director's ownership and liquidity actions within MIAX, and the accompanying financial and market-share data underscore recent operational momentum at the exchange group. The 10b5-1 plan disclosure clarifies that the sale followed a pre-arranged program rather than being an immediate reaction to company developments.

Risks

  • MIAX reported a trailing twelve-month EPS of -$1.00, indicating recent unprofitability that introduces earnings recovery risk for investors; this primarily affects market participants in financial exchanges and equity derivatives.
  • Analyst projections of EPS of $1.68 for fiscal 2026 represent a forecast rather than realized results, creating execution risk if the company fails to meet those expectations; this carries implications for institutional investors and options market participants.
  • The director's sale, though executed under a pre-arranged 10b5-1 plan, represents insider liquidity which investors may interpret in different ways; this can influence short-term trading dynamics in MIAX shares within equity markets.
