Miami International: Not Trading This Exchange Yet

Miami International Holdings (MIAX) experienced a strong debut, trading at a significant revenue discount to peers despite its operating margins lagging, though projected to reach 25% by H1 2025. While valued at over 6x sales and 25x operating profits post-IPO, making it not cheap on earnings, its upside is contingent on closing the profitability gap with industry leaders like CBOE and ICE, positioning it as a compelling post-IPO watch given its relative valuation and margin trends.

Analysis

Miami International Holdings (MIAX) has executed a successful public debut, presenting a complex valuation case for investors. The company currently trades at a significant revenue discount relative to its peers, but this is counterbalanced by lagging operating margins. While profitability trails industry leaders such as CBOE and ICE, MIAX is demonstrating improving operating leverage, with a projection for margins to reach 25% in the first half of 2025. Post-IPO, the stock is valued at over 6 times sales and 25 times operating profits, a multiple that is not considered inexpensive on an earnings basis. The primary investment thesis hinges on the company's ability to successfully close the profitability gap with its competitors, making its margin trajectory the key factor to monitor going forward.

Key Decisions for Investors

• Given the valuation is not cheap on an earnings basis post-IPO, investors should consider monitoring the stock's performance and margin progression before establishing a position, rather than chasing the initial rally.
• The central catalyst for MIAX is its ability to improve profitability; therefore, tracking progress toward the projected 25% operating margin for H1 2025 is critical for validating the investment thesis.
• A thorough relative valuation against peers like CBOE and ICE is prudent to determine if the current revenue multiple discount sufficiently compensates for the existing margin gap and associated execution risk.
