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%. GAAP net income was $52.5 million versus a $102.1 million loss a year earlier, while adjusted diluted EPS rose to $0.45 from $0.42. Options average daily volume grew 15.2% to 11.1 million contracts and market share edged up to 17.4%; MIAX lowered full-year adjusted operating expense guidance to $254–$257 million from $260–$270 million.

Analysis

The earnings quality is better than the headline suggests in one respect and weaker in another: options volume outgrew the market, but only by a modest 0.2-point share gain, while revenue per contract fell 4.9%. That combination points to volume-led growth with pressure on monetization—potentially mix, fee economics or liquidity incentives—not yet durable pricing power. Since options supplies most of MIAX’s net revenue, sustained RPC erosion would matter more than near-term share gains. The sharp adjusted EBITDA expansion also reflects prior-year comparability distorted by IPO-related costs; it should not be extrapolated as a new run-rate. Adjusted results include a $6.3 million provision for CAT costs deemed unrecoverable, a reminder that exclusions do not remove operating and recovery risks.

Near term, lower expense guidance and the options volume trend support the stock, but the guidance reduction is modest relative to the revenue base. Over 1–3 months, watch options RPC and share gains against industry volumes; volume growth without stable unit economics would weaken the growth multiple case. Equities remains small and its reported segment improvement does not offset falling MIAX equity share. Futures is an option on longer-term diversification, not yet a current earnings driver: the segment remains loss-making and financial futures RPC is negative. Over 6–18 months, successful new product distribution could diversify revenue, but launch claims need validation in contract volumes and segment losses. Consensus risk is treating 54% adjusted EBITDA margin as evidence of structurally higher profitability before monetization and new-business economics are proven.

Key Decisions for Investors

• Constructive but not a chase: consider a modest long MIAX after the initial earnings reaction, preferably on a pullback that holds the pre-release closing level. Reassess if options RPC continues to decline or market-share gains reverse; no price target without valuation and market-price context.
• For the next 1–3 months, track quarterly options RPC alongside market share and ADV. Falsification: continued share gains accompanied by stabilizing/improving RPC would invalidate the monetization concern; falling share or further RPC compression would weaken the long thesis.
• Treat futures launches as a watch item, not a standalone catalyst trade. Verify contract growth, RPC improvement—especially financial futures—and narrowing adjusted EBITDA losses before assigning meaningful diversification value.
• Do not annualize the 47% adjusted EBITDA growth or rely on the GAAP EPS comparison; separate recurring exchange economics from prior-year IPO costs, digital-asset marks, and the CAT-cost provision when updating estimates.
