Miami International Holdings Reports Third Quarter 2026 Results

MIAX reported Q3 2026 net revenue up 20% year over year to $131.0 million and adjusted EBITDA up 47% to $70.8 million, with margin expanding to 54% from 44%; adjusted diluted EPS was $0.45 versus $0.42. Options average daily volume grew 15.2% to 11.1 million contracts and market share edged up to 17.4%, though revenue per contract declined 4.9% to $0.098. The company lowered its FY2026 adjusted operating expense guidance to $254–$257 million from $260–$270 million and reduced its adjusted effective tax-rate range to 26%–28% from 27%–29%.

Analysis

MIAX’s earnings support a constructive but selective read: the core options franchise is growing, yet this quarter does not establish accelerating share capture. Options volume rose alongside industry volume, while share gained only 0.2 points and revenue per contract fell 4.9%. The key monitor is whether member/access-fee growth and volume can offset continued pricing and liquidity-payment pressure—not headline contract growth alone. The lower adjusted-expense midpoint is a modest earnings tailwind, but the year-on-year margin comparison is flattered by prior-period IPO/share-compensation costs; options-segment adjusted EBITDA growth is a more useful operating signal than consolidated growth.

Second-order risk sits in the smaller businesses: equities remains loss-making despite improved capture, and MIAX’s options strength does not offset its declining U.S. equities share. Futures remain structurally investment-stage, with negative adjusted EBITDA and financial-futures RPC below zero; new contracts and distribution through NinjaTrader could build participation, but may require incentives before economics turn positive. This creates upside optionality, not near-term earnings visibility. Strong liquidity limits financing risk, while reported GAAP and nine-month earnings are poor run-rate anchors given unusual tax, asset-sale and digital-asset items. Over 1–3 months, watch options RPC, share, and member connections; over 6–18 months, test whether futures launches convert into positive contribution economics. No valuation or estimate data are supplied, so the earnings beat’s attractiveness at the current price cannot be established.

Key Decisions for Investors

• Consider a staged long MIAX rather than chasing the initial reaction: add only if subsequent data show options share holding or rising while RPC stabilizes. The upside case is operating leverage in a high-margin core; the risk is volume growth masking deteriorating monetization. Verify valuation and post-report price action before sizing.
• Track options RPC, market share, and access-fee/member-connection growth over the next 1–3 months. Falsify the constructive thesis if share retreats toward or below the year-ago level while RPC continues to fall, or if management lowers the expense outlook.
• Treat futures as a watch item, not a separately underwritten growth driver yet. Require evidence of improving financial-futures RPC and narrowing segment adjusted EBITDA losses before attributing material value to new contracts or NinjaTrader distribution.
• Do not annualize GAAP earnings or the consolidated margin expansion. Reassess using recurring options economics and adjusted expenses, while checking how often CAT-related provisions and other excluded costs recur; recurring exclusions would weaken the quality-of-earnings case.
