Miami International Holdings, Inc.MIAX

Miami International Holdings (MIAX) reported $369.7M revenue and $170.2M net income for Q1 2026, operating with $550.8M cash reserves and $1.07B equity. The self-described 'innovator in derivatives markets' still sells historical trading data on physical USB drives-eight terabytes per client, suggesting someone in IT still uses the term 'portable storage devices' unironically.

MIAX’s core business revolves around data services for options and equities markets, offering real-time feeds, historical archives, and market data licensing. With $46M operating income and just $11.7M capex, the company’s cash generation appears sturdy, though its reliance on legacy data products raises questions in an era of cloud-first competitors.

Recent filings reveal a management desks active in share disposals: three insider transactions in July alone, including a $1.2M sale by a director. Meanwhile, the July 21 8-K hints at executive pay changes without disclosing numbers, leaving investors to ponder how 'cash-generative' aligns with insider selling at a 18.5x P/E.

The company scheduled its Q2 earnings call for August 5, though no new financial data has been released since March. With $60.9M operating cash flow and no debt mentioned in filings, the lack of updates feels less like caution and more like a deliberate pause before what could be a critical disclosure period.

Risks include overreliance on data services (69% of revenue per 10-Q), thin liquidity in shares traded (average $4.2M daily volume), and the evergreen threat of exchange competitors undercutting its USB-drive-as-a-service model. Catalysts hinge on Q2 results and whether insider sales accelerate.
