Deitzel Edward

EVP/CRO exercises options, immediately sells all shares at 3.9x cost basis in same-day wash.

Edward Deitzel, the company's Executive Vice President and Chief Risk Officer, exercised 11,000 stock options at $12 per share and sold the entire position the same day at $47.28, banking a substantial gain of approximately $388,000 net. This is a mechanical exercise-and-sell transaction with no meaningful increase in his stock ownership—he ended with the same number of shares he held before the trade. However, his execution timing stands out: across three prior sales at MIAX, the stock subsequently gained in each instance, indicating consistently poor timing on his exits. This current transaction occurs while the stock trades near its 52-week high after climbing sharply over the preceding months, and while the company continues to operate at a loss despite growing revenue. Deitzel's repeated pattern of selling into strength—combined with the company's ongoing unprofitability—suggests he is prioritizing liquidity and profit-taking rather than demonstrating conviction in the business. The fact that this is his fourth open-market sale in the past three years, with no offsetting open-market purchases during the same period, reinforces a net-reduction trend in his insider holdings.

EVP/CRO/CCO Deitzel sold 12,335 shares at avg $42.01 for $518,221.44 on 2026-04-07/08

Edward Deitzel, serving as Executive Vice President, Chief Risk Officer, and Chief Compliance Officer at MIAX Exchanges, executed three separate sales totaling 12,335 shares (12.3K shares) for $518,221.44 ($518.2K) at an average price of $42.01, reducing his holdings from 128,556 shares to 116,221 shares (a -9.6% reduction). The transaction occurred near the 52-week high of $50.96, with the stock currently trading 18.9% below that peak at $41.35, indicating the sales preceded a material pullback in valuation. His cross-ticker track record shows one prior buy at this company (2025-08-13) that delivered +62.9% over 30 days and +115.1% over 90 days, demonstrating prior capability to identify entry points, but this filing represents a discrete exit at elevated levels rather than a continuation of conviction. The company faces profitability pressures with a full-year net loss of $-102,080,000.00 ($-102.1M) despite quarterly revenue of $339,778,000.00 ($339.8M) and annual revenue growth of +19.6%, creating a backdrop of operational stress that may have influenced the timing of this reduction in equity exposure.

EVP/CRO/CCO Deitzel buys 100 MIAX shares at $23.00; 9 other insiders also bought within 14 days (cluster pattern).

Deitzel Edward, EVP Chief Risk Officer and Chief Compliance Officer, purchased 100 shares of MIAX at $23.00 on 2025-08-13, bringing his holdings to 32,193 shares (32.2K shares). This purchase is part of a broader pattern: 9 other insiders also bought within the past 14 days, indicating coordinated insider accumulation around the company's recent IPO. The stock is trading at $31.12 as of 2025-08-15, just 2 trading days after listing, reflecting typical early post-IPO volatility. The cluster buy activity suggests multiple company insiders viewed the offering price as attractive, though the significance is tempered by the minimal position increase (100 shares, +0.3% of holdings) and the very early stage of trading data available.
