KEMPER J MARINER

CEO Kemper J Mariner sold 18,714 shares at blended $128.68 for $2.4M, retaining 1.51M shares post-sale.

Mariner executed three separate sales totaling 18,714 shares for $2,408,023.97 at prices ranging from $128.04 to $129.19 on 2026-02-02, representing a -1.2% reduction in his 1.52M share position. The sales occurred near the stock's 52-week high of $128.05, with the current price at $127.96, and follow a period of substantial upside momentum: 30-day +9.9% and 90-day +19.4%. His prior trades at UMBF show a pattern of well-timed exits: 4 of 4 measurable prior sales resulted in negative 90-day returns, indicating he has historically sold before subsequent declines at this ticker. However, timing characterizations are best viewed alongside the context that he retains a substantial 1.51M share position, maintaining significant direct exposure to UMBF's performance despite the recent reductions.

UMBF: CEO Kemper Mariner sold 15,367 shares at $114.58 on 2025-12-08; holds 1.52M post-sale.

Kemper Mariner, Chairman and CEO of UMB Financial Corp, sold 15,367 shares at $114.58 for total value of $1,760,750.86, reducing his holdings from 1.54M shares to 1.52M shares. His prior trades at UMBF (5 sales in September 2025) showed negative 30-day and 90-day returns, with 2 of 2 prior measurable outcomes well-timed at the 90-day mark (stock declined after sale). His cross-ticker track record shows a 29.41% well-timed rate on 20 prior sells with an average 90-day return of +7.1%. The current stock price of $114.24 is 10.1% below the 52-week high and up 4.8% over 30 days, despite UMBF's solid fundamentals (P/E 14.30, net income $188.3M, market cap $8.7B). The sale represents a modest 1.0% reduction in his ownership stake.

UMBF CEO Mariner sells 4,500 shares for $561.4K; 36.0% reduction in holdings over two days

CEO Kemper Mariner executed 5 separate sales totaling 4,500 shares for $561,380.00 at an average price of $124.75 on 2025-09-09 and 2025-09-10, reducing his holdings from 12,500 to 8,000 shares (a -36.0% reduction). The stock currently trades at $121.68, down 4.6% from its 52-week high of $127.60, placing the transaction prices near the upper end of the 52-week trading range. The company's P/E of 17.48 and strong net income of $217.4M reflect a healthy financial profile. Notably, Mariner's cross-ticker track record shows avg 30d return +6.8% and avg 90d return +11.8% following his prior sells—indicating his past sales have been poorly timed overall (stock rising after his exits). His same-ticker history at UMBF is mixed: 2 of 4 prior measurable sales were well-timed, while 2 were poorly timed (dec 2024 sales followed by declines). This transaction's timing signal is ambiguous given the divergent outcomes in his historical pattern.

UMBF Chairman/CEO Mariner sold 15,523 shares at $116.33 on 2025-08-13; holds 1.54M shares post-trade.

Kemper Mariner, Chairman and CEO of UMB Financial Corp, sold 15,523 shares valued at $1,805,742.47, reducing holdings by 1.0% to 1,536,781 shares. The sale price of $116.33 is 8.3% below the 52-week high of $127.60, though the stock has gained 9.6% over the past 30 days and 9.4% over 90 days. His cross-ticker track record across 20 prior open-market sales shows an average 90-day return of 11.2% with a well-timed rate of 11.11%, but at UMBF specifically, prior sales show mixed outcomes: 2 of 3 measurable same-ticker sales achieved positive returns at the 90-day mark, while the most recent two June 2025 sales remain unmeasured. The small percentage reduction in absolute shares and modest sale size relative to a $8.9B market cap and net income of $217.4M suggest a routine portfolio adjustment from an executive who remains heavily invested in the company.

The current price is $102.13, near the transaction price; the stock trades 20.0% below its 52-week high of $127.60 and has returned 1.8% over the past 30 days. Mariner's prior five sales at UMBF show mixed timing outcomes—two of five were well-timed at the 90-day mark—while his broader cross-ticker track record shows a 10.00% well-timed rate across 20 prior sells with an average 90-day return of 11.6%, suggesting he typically sells into strength rather than before declines. The transaction itself represents routine portfolio management at a valuation near recent trading levels, with no apparent signal of material concern or conviction.
