Non-officer Bass buys 2,095 BXSL shares at market; stock down 28% from 52-week high, third open-market purchase at this ticker in 36 months.

Robert Bass purchased approximately 2,100 shares of Blackstone Secured Lending Fund on a down day, adding to his existing position when the stock trades significantly below its 52-week high. This is his third open-market purchase at BXSL in the past three years, continuing a pattern of accumulation in the company. His timing on prior purchases at this ticker has been mixed: one of his earlier purchases was followed by modest gains over a three-month period, while his other earlier purchase saw the stock decline slightly over the same horizon. The company remains profitable with solid earnings, which provides fundamental support for a buyer at depressed valuations. Bass is not an officer or director, so this trade reflects his personal investment decision rather than insider conviction about near-term catalysts.

Insider Enns Lucie buys 1,045 shares of BXSL at $23.48; stock down 29.8% from 52-week high. Cluster of 2 other insiders buying within 14 days.

Lucie's purchase of 1,045 shares ($24.5K) at $23.48 occurs as BXSL trades 29.8% below its 52-week high and 4.4% lower over the past 30 days. The transaction gains weight from the fact that 2 other insiders also bought within the past 14 days, forming a cluster buy pattern at depressed price levels. This multi-insider activity within a tight window suggests coordinated interest in the fund at current valuations, though the stock's ongoing 15.5% decline over 90 days and near-52-week lows warrant assessment of whether this represents conviction or opportunistic accumulation near a support level.

Clark James Frederic bought 750 BXSL shares at $23.78; stock down 29.3% from 52-week high; prior buy at this ticker returned -5.6% at 90 days.

Clark James Frederic purchased 750 shares of Blackstone Secured Lending Fund at $23.78 on 2026-03-11, increasing his holdings by +37.5% to 2,750 shares. The purchase occurs as the stock trades at $23.71, positioned -29.3% from its 52-week high of $33.53 and down -7.6% over the past 30 days. His prior buy at BXSL on 2025-11-11 ultimately returned -5.6% at the 90-day mark, and across his cross-ticker track record, his 2 prior buys averaged 90d return of -5.6% with a 0.00% win rate. The current acquisition appears to follow a pattern of purchasing activity at this holding despite weak recent price momentum and a historical track record of negative returns over the subsequent three months.

COO Katherine Rubenstein buys 1,035 shares of BXSL at $24.08; stock down 28.4% from 52-week high.

Katherine Rubenstein, Chief Operating Officer, purchased 1,035 shares at $24.08 on 2026-03-10, increasing her holdings to 5,770 shares from 4,735 shares (+21.9%). The transaction occurred when the stock traded at a substantial discount to its 52-week high of $33.53, currently sitting 28.4% below that peak, with a 90-day decline of 14.6%. The company shows solid fundamentals with net income of $132,437,000.00, a P/E of 11.88, and a market cap of $5,572,392,665.89. The purchase by a COO during a period of price weakness represents incremental accumulation in the securities of the fund she serves, though the modest share count and lack of prior comparative transaction history limit the signal strength.

Insider Clark James Frederic buys 2,000 shares of BXSL at $26.68, inaugural purchase; stock down 22.8% from 52-week high.

Clark James Frederic purchased 2,000 shares of Blackstone Secured Lending Fund at $26.68, representing his first open-market buy across his trading history. The current price of $26.62 shows minimal movement since transaction, though the stock is trading 22.8% below its 52-week high of $34.50 and down 10.7% over the prior 90 days. The fund carries a healthy 10.28 P/E and $6.2B market capitalization with $132.4M in net income, suggesting a established financial vehicle. As a debut purchase and given the modest position size relative to fund fundamentals, this transaction warrants monitoring to assess whether it represents the beginning of an insider accumulation pattern or a standalone opportunistic entry.

Bass buys 3,760 BXSL shares at $26.63; stock down 25.4% from 52-week high, now trading at $25.75

Robert J Bass purchased 3,760 shares of Blackstone Secured Lending Fund at $26.63, increasing his holdings by 21.6% to 21,167 shares. The purchase occurred as BXSL trades 25.4% below its 52-week high of $34.50 and has declined 17.2% over the past 90 days. His single prior BXSL purchase on 2025-05-13 yielded a -1.4% 90-day return, and his cross-ticker track record shows an average 90-day return of -3.9% with a 20.00% win rate, indicating his prior buys have not consistently preceded price appreciation. The transaction is modest in scale relative to his existing position, and the stock's recent weakness provides limited context for whether this represents conviction or a routine rebalancing activity.

Blackstone Secured Lending insider Robert J Bass buys 1,626 shares at $30.78; holdings rise 10.3% to 17,403 shares

Robert J Bass purchased 1,626 shares of BXSL at $30.78, increasing his total holdings by 10.3% to 17,403 shares and committing $50,048.28 in capital. The stock currently trades at $31.12, within its 52-week range of $26.88–$34.50, suggesting modest upward movement since the transaction. Bass's cross-ticker track record shows 5 prior open-market buys with an average 90-day return of -3.6% and a 33.33% win rate, indicating his buy timing has not systematically generated outperformance. The lack of same-ticker historical data limits the ability to assess whether this purchase reflects a pattern at BXSL specifically.
