Mattias Stetz

COO Mattias Stetz sells 20,000 shares of RSI at $25.63; 10b5-1 plan execution with stock down 8.4% in 30 days.

Mattias Stetz, Chief Operating Officer, sold 20,000 shares at $25.63 on 2026-06-01 under a pre-arranged 10b5-1 trading plan, reducing his holdings by 8.4% to 217.9K shares. This is a scheduled, non-discretionary transaction. The stock has declined 8.4% over the 30-day period and is currently -13.1% from its 52-week high of $29.24, though it remains up 21.7% over 90 days. His prior trades at RSI show mixed outcomes: four sales in early May posted modest 1.9% gains at both 30 and 90 days, while an earlier May 1st sale resulted in -9.8% and -9.5% returns respectively at those horizons. The company's fundamentals show revenue of $370.4M with 22.8% annual growth, though the P/E of 141.22 reflects a premium valuation relative to net income of $9.1M.

COO Mattias Stetz liquidates all remaining holdings via series of open-market sales, continuing 49-trade selling pattern with poor historical timing.

Mattias Stetz, the company's Chief Operating Officer, has executed a complete exit from his RSI holdings through a sequence of open-market sales totaling approximately 86,675 shares over two consecutive trading days. This represents the continuation of an extraordinary pattern: Stetz has now completed 49 open-market sales in the 36-month window without a single open-market purchase, meaning this filing caps a strategy of systematic liquidation. The historical record is uniform and unfavorable: all five of his prior RSI sales saw the stock rise afterward, indicating consistently poor timing on his exits—each time he sold, the company's shares subsequently appreciated. Despite this track record of mistimed exits, the stock now trades well below its 52-week high while the company remains profitable with revenue growing in the low twenties. Stetz's complete liquidation of his position stands as a notable outlier in the executive ranks, raising questions about his confidence relative to the company's operational fundamentals.

RSI COO STETZ sold 20,000 shares at $28.09; stock at $28.33; 30d +29.1%, 90d +60.3%

Mattias Stetz, Chief Operating Officer of Rush Street Interactive, sold 20,000 shares on 2026-05-01 at $28.09, reducing his holdings from 257,874 to 237,874 shares. The sale occurred as the stock was trading near its 52-week high of $28.33 (+0.0% from peak), following a sharp 29.1% gain over the prior 30 days and 60.3% over 90 days. The sale itself remains small relative to his remaining position (7.8% reduction). This flagged derivative-conversion transaction should be understood as a partial sale of a specific batch rather than a position exit, and the insider's full position including derivative securities is not yet fully captured in available Form 4 Table I data. Across his five most recent trades at RSI, three occurred on 2026-03-04, with the earliest measurable showing a +12.2% return 30 days out; timing patterns at this specific ticker remain incomplete and difficult to assess.

COO Mattias Stetz sells 70,000 RSI shares at $24.06–$27.44 for $1,853,309; stock up 35.2% in 30d, 57.4% in 90d.

Mattias Stetz, Chief Operating Officer of Rush Street Interactive, executed 2 separate sales totaling 70,000 shares for $1,853,309, reducing his holdings to 0 shares post-transaction. The sales occurred at $24.06 on 2026-04-27 and $27.44 on 2026-04-29, with a blended average price of $26.48. Since the filing date, the stock has appreciated 35.2% over 30 days and 57.4% over 90 days, reaching the 52-week high of $27.98, indicating the insider sold before a substantial rally. At the RSI ticker, Stetz's 5 prior trades in March 2026 showed strong 30-day forward returns (+12.2% to +13.0%) but 90-day outcomes are not yet measurable; his broader cross-ticker track record across 20 prior sells shows an average 90-day return of +15.5%, which reflects poorly-timed sell exits. However, the FLAG indicates the transactions involve derivative conversions; the insider's true position may include unrealized derivative holdings not captured in Table I. The sale warrants context from derivative holdings before full significance can be assessed.

COO Mattias Stetz sells 110,000 RSI shares (30.6% reduction) across 9 trades for $2.2M at $20.03 avg, Mar 2-4

Chief Operating Officer Mattias Stetz executed 9 separate sales totaling 110,000 shares (110.0K shares) for $2,202,972.21 ($2.2M) between March 2–4, 2026, reducing his holdings from 359,624 shares to 249,624 shares (a 30.6% reduction). The transactions occurred near the 52-week high, with prices ranging from $19.88 to $20.22 and a blended average of $20.03, versus the current price of $20.38. At RSI specifically, Stetz's prior 5 trades show mixed outcomes: his most recent prior sales (Jan 2, 2026) have delivered -7.4% returns over 30 days, while older sales (Dec 2025, Nov 2025) showed positive 30-day and 90-day returns; 0 of 2 measurable same-ticker sales at the 90-day mark have been well-timed. The company's financials show strong growth (annual revenue +22.8%) and a high P/E of 67.93, reflecting investor expectations already embedded in valuation. The multi-transaction structure across three trading days and the magnitude of the reduction warrant attention to whether this reflects a specific liquidity need, scheduling plan, or portfolio rebalancing decision on the part of the COO.

RSI COO Mattias Stetz sells 110,000 shares ($2.1M) at $19.09; post-sale hold is 144,806 shares

Mattias Stetz, Chief Operating Officer of Rush Street Interactive, executed 3 separate sales totaling 110,000 shares for $2,099,581.00 at $19.09 on 2026-01-02, reducing his holdings by 43.2% to 144,806 shares. The sale occurs at a price 1.7% below the current market price of $19.44 and 15.3% below the 52-week high of $22.53, suggesting execution in a relatively subdued trading environment. Stetz's prior 5 trades at RSI show mixed timing outcomes (2 of 3 measurable 90-day returns were negative, indicating well-timed sells in those cases), but his broader cross-ticker track record shows an 8-trade average 90-day return of +17.3% following sells—a poorly-timed pattern—with a well-timed rate of only 33.33%. The FLAG indicates this sale involves a derivative-conversion transaction, meaning the 144,806 post-transaction share count in Table I does not represent his total equity exposure; derivative holdings in Table II are not yet available, so the full position size and any protective or leveraged components cannot be assessed from this filing alone.

COO Stetz sells 30,000 RSI shares at $18.51; stock now at $18.67, down 17.1% from 52-week high.

Mattias Stetz, Chief Operating Officer, sold 30,000 shares (representing a 15.4% reduction in his pre-transaction holdings) at $18.51 on 2025-12-01, realizing $555,200 in proceeds. The sale occurred near the stock's current price of $18.67, positioning the transaction in the lower portion of the 52-week range ($9.68–$22.53) where the stock is down 17.1% from its high. Examining Stetz's execution pattern at Rush Street Interactive: his prior three measurable trades at this ticker produced mixed near-term outcomes (losses of 15.6% and 10.0%, versus a gain of 15.5%), with 2 of 3 well-timed at the 90-day mark by selling before declines. The company's fundamentals show strong top-line growth of +33.7% year-over-year with $277.9M in quarterly revenue, though profitability remains modest at $6.1M net income and the valuation is stretched at a P/E of 124.47. This sale represents the insider's second discretionary transaction at RSI in under two months, warranting monitoring of whether continued selling reflects a shift in conviction or simply rebalancing activity amid recent price volatility.

COO Mattias Stetz sells 30,000 RSI shares at $17.09; stock down -26.2% from 52-week high, -11.1% in 30 days.

Mattias Stetz, Chief Operating Officer of Rush Street Interactive, sold 30,000 shares (30.0K shares) at $17.09 on 2025-11-03 for $512,691.00 ($512.7K), reducing his holdings by 13.3%. The sale occurred as RSI trades -26.2% below its 52-week high of $22.53 and has declined -11.1% over the prior 30 days, despite the company reporting $277,911,000.00 ($277.9M) in latest quarterly revenue and +33.7% annual revenue growth. Across Stetz's same-ticker history at RSI, his prior five sales show mixed timing outcomes: 1 of 3 measurable 90-day outcomes was well-timed (stock fell after the sale), while two recent 2025-10 and 2025-09 sales occurred before -15.6% and -10.0% 30-day declines, though their 90-day results remain unmeasured. The current sale occurs during a period of stock weakness and follows a pattern of elevated selling activity at this ticker in recent months.

COO Mattias Stetz sells 30,000 RSI shares at $20.10; holds 224.8K post-transaction as stock trades -10.1% over 30 days

Mattias Stetz, Chief Operating Officer of Rush Street Interactive, sold 30,000 shares (11.8% of his pre-transaction holdings of 254.8K shares) at $20.10 on 2025-10-01, generating $603.1K in proceeds. The timing context is mixed: the stock has declined 10.1% over the past 30 days and is 11.0% below its 52-week high of $22.53, yet has gained 33.3% over the past 90 days. His prior trades at RSI show no well-timed pattern at the 90-day mark (0 of 3 prior measurable sells occurred before subsequent declines), and his cross-ticker track record shows an average 90d return of +43.2% after sells—meaning he tends to exit before price gains, not before declines. The company's fundamentals remain robust with $269.2M in latest-quarter revenue, $16.7M net income, and 33.7% annual revenue growth, though the P/E ratio of 167.08 reflects elevated valuation expectations.

COO Stetz sells 30,000 RSI shares at $21.45; stock +66.5% in 90 days, prior RSI sales show mixed 90d timing (0 of 1 well-timed)

STETZ MATTIAS sold 30,000 shares at $21.45, reducing his RSI holdings by 10.3% to 261,051 shares. The sale occurred while RSI stock has appreciated 66.5% over 90 days and 8.0% over 30 days, trading near its 52-week high of $22.33 at current price $21.28. His same-ticker sales history at RSI shows three recent sells (July 1, July 3, August 1) with strong positive 30-day returns (36.2%, 29.0%, 15.5%), but his one measurable 90-day outcome from March 2024 produced a positive 90-day return (+44.8%), indicating he sold before a substantial rally rather than before a decline—a poorly timed exit at that mark. The current sale follows an accelerating multi-month run-up in the stock, and investors should monitor whether this establishes a pattern of selling into strength at RSI or represents a single rebalancing activity by the COO.
