Executive Chairman Carter Thomas L Jr buys 1,120 shares at $13.50; strong 20-trade track record with 93.75% 90d win rate

Carter Thomas L Jr, the Executive Chairman, purchased 1,120 shares at $13.50, adding to a substantial 3,682,724 share post-transaction position, signaling continued confidence in BSM's value proposition. His track record is highly material: across 20 prior buys, he has achieved a 93.75% win rate over 90 days with an average 90-day return of +9.8%, demonstrating consistent judgment in identifying entry points. The company's fundamentals remain solid with $59,359,000.00 in latest-quarter revenue and $13,272,000.00 net income, supported by annual revenue growth of +8.4%, providing a stable foundation for the insider's conviction. The current price of $13.78 sits at -11.0% from the 52-week high, creating a potential entry opportunity that aligns with this executive's historical pattern of buying near cycle lows.

Executive Chairman Carter Thomas makes three open-market purchases totaling ~68K shares as stock trades well below 52-week highs; repeat buyer with flawless track record at this ticker.

Carter Thomas, as Executive Chairman, made three purchases within a four-day window, acquiring nearly 68,000 shares worth approximately $909,000 at an average price near current levels. The stock is trading roughly 13% below its 52-week high and has declined over the past three months, yet Thomas is buying into this weakness—a pattern consistent with his prior Form 4 activity, which shows 20 prior open-market purchases with zero sales. Most significantly, his five previous purchases at this same ticker were followed by stock appreciation at both the 30-day and 90-day horizons; every prior buy proved well-timed. The company remains profitable with growing revenue, providing a fundamental backdrop that suggests Thomas is buying into a financially sound business at lower prices rather than catching a falling knife. This represents his 21st, 22nd, and 23rd open-market purchases in the 36-month window—a sustained accumulation pattern by someone with direct operational knowledge of the business.

CEO Carter Thomas L Jr bought 15,300 shares at blended $12.57 on 2025-09-11/12; stock now -19.6% from 52-week high

CEO Carter Thomas L Jr executed 2 separate purchases totaling 15,300 shares for $192,312.95 on 2025-09-11 and 2025-09-12 at a blended average price of $12.57, increasing his holdings to 3.51M shares (a +0.4% increase). The current price of $12.53 is -19.6% below the 52-week high of $15.59 and has declined -10.0% over the past 90 days. Notably, this purchase follows a rapid sequence of five buys at BSM within the preceding month (2025-08-19 through 2025-09-10), suggesting sustained accumulation as valuations have compressed. The company's fundamentals show revenue declining -26.8% annually, and the insider's cross-ticker track record of 18 prior buys reflects a -7.0% average 90-day return with an 11.11% win rate, indicating historically weak timing on such accumulations. Without scheduled trading plan disclosure, the pattern of near-daily purchases during a declining price period warrants scrutiny into whether these reflect opportunistic conviction or external drivers.

CEO Carter Thomas L Jr purchases 25,370 shares (3 transactions) at blended avg $12.08; 5th consecutive buy at BSM in Aug-Sep

Carter Thomas L Jr, CEO/President/Chairman, executed 3 separate purchases totaling 25,370 shares for $306,501.13 between 2025-09-08 and 2025-09-10 at a blended average price of $12.08. This marks the fifth consecutive buy at Black Stone Minerals in a span of less than a month, following prior acquisitions on 2025-08-08, 2025-08-11, 2025-08-12, 2025-08-19, and 2025-08-20. The current stock price of $12.32 remains 21.0% below the 52-week high of $15.59, and the company's annual revenue has contracted 26.8% year-over-year, indicating a challenging operating environment despite strong current net income of $120,028,000.00. The insider's cross-ticker track record shows weak timing outcomes (90d win rate 11.11%, avg 90d return -7.0%), and none of his prior BSM trades have yet achieved positive 90-day returns, which tempers the significance of the repeated acquisition pattern in an otherwise depressed valuation context.

CEO Carter Thomas L Jr bought 41,000 shares of BSM for $491,949.50 in 2 trades; stock down 22.7% from 52-week high.

Carter Thomas L Jr, CEO and Chairman, executed 2 open-market purchases totaling 41,000 shares at a blended average price of $12.00 on consecutive days (August 19–20, 2025), increasing his holdings by 1.2% to 3,472,031 shares. The current price is $12.05, only 0.4% above the transaction prices, while the stock trades 22.7% below its 52-week high of $15.59 and is down 10.5% over 90 days. Notably, Carter's prior same-ticker purchases at BSM (4 additional buys within the preceding 12 days, all with outcomes not yet measurable) and his 5-trade BSM history show only 0 of 1 measurable prior buy was well-timed on a 90-day basis; his cross-ticker track record spans 13 prior buys with a 11.11% 90-day win rate and average 90-day return of -7.0%. Meanwhile, the company's latest quarter shows annual revenue declined 26.8% year-over-year, creating a contrasting backdrop against persistent insider accumulation at depressed levels.

BSM CEO Carter Thomas L Jr purchased 9,200 shares at $12.36; stock down 8.7% in 90 days

Carter Thomas L Jr, BSM's CEO, President, and Chairman, purchased 9,200 shares on 2025-08-12 at $12.36, bringing his total holdings to 3,431,031 shares. The transaction occurs in a deteriorating price environment: the stock is -8.7% over 90 days and -20.1% from its 52-week high of $15.59. His prior trades at BSM show mixed results—one prior buy from 2024-09-06 yielded positive 90-day returns (+6.8%), but more recent purchases on 2025-05-21, 2025-08-07, 2025-08-08, and 2025-08-11 remain unmeasured or marginally negative. Across his broader cross-ticker track record, his 12 prior open-market buys averaged -6.4% over 90 days with only a 12.50% win rate, suggesting a pattern of poor timing on purchases. Meanwhile, company fundamentals show annual revenue decline of -26.8%, though the latest quarter generated $159,494,000.00 in revenue and $120,028,000.00 in net income. The clustering of four buy transactions at BSM within five days (2025-08-07 through 2025-08-12) is notable and warrants investigation into whether these reflect a formal trading plan or discretionary positioning decisions.

Carter Thomas L Jr (CEO) acquired 72,210 shares across 3 purchases at blended avg $12.18 ($879.3K) at BSM amid -26.8% annual revenue decline

CEO Carter Thomas L Jr purchased 72,210 shares over three days (Aug 7–11, 2025) at prices ranging from $12.10 to $12.24, bringing total holdings to 3,421,831 shares. The current price of $12.06 is below the transaction blended average of $12.18, and the stock is -22.6% from its 52-week high and down 9.4% over 30 days. At the same-ticker level, his prior 5 buys at BSM show mixed outcomes: one produced +8.7% return in 30 days and +6.8% in 90 days, but three others declined in the 90-day window, and his timing success rate at this ticker is 1 of 4 (25%). More significantly, fundamental headwinds are evident: Black Stone Minerals reported annual revenue decline of -26.8% year-over-year despite recent quarterly revenue of $159.5M and net income of $120.0M. The purchase occurs in a context of negative price momentum and industry-level revenue contraction, without a clear indication of a catalytic inflection point supporting the timing of these acquisitions.

CEO Carter Thomas L Jr bought 14,500 BSM shares at $13.52 on 2025-05-21; stock down -17.0% from 52-week high of $16.25

CEO Carter Thomas L Jr purchased 14,500 shares of Black Stone Minerals at $13.52, adding to a base of 3.35M shares post-transaction. The buy occurred as the stock trades $13.49 currently, -17.0% below its 52-week high of $16.25 and down -5.8% over the prior 30 days. Examining prior trades at this same ticker, his 5 previous buys at BSM show mixed outcomes: only 1 of 5 achieved positive 90-day returns, with an average 90-day return of -2.8% across those trades. Cross-ticker, his broader track record (8 prior open-market buys) shows an average 90-day return of -6.4% with a win rate of 12.50%. Company fundamentals present headwinds: while the latest quarter generated $59.3M in revenue with $15.9M net income, annual revenue declined -26.8% year-over-year, signaling a deteriorating top-line trend that contextualizes the stock's recent price weakness.

CEO Carter Thomas L Jr bought 100,000 BSM shares at $14.12 on 2024-09-06; holds 3.13M shares post-transaction.

CEO Carter Thomas L Jr purchased 100,000 shares of Black Stone Minerals, L.P. at $14.12 on 2024-09-06, increasing his holdings from 3.03M to 3.13M shares. The timing context is material: the stock trades at $14.05 today, 23.5% below its 52-week high of $18.36, and his own same-ticker buy history at BSM shows 0 of 5 prior buys were well-timed at the 90-day mark, with an average 90-day return of -7.2%. Fundamentals show annual revenue contracted 10.8% year-over-year despite solid absolute quarterly metrics ($109.6M revenue, $68.3M net income), suggesting structural headwinds. This purchase adds 3.3% to his existing stake but does not contradict the established pattern of poor timing execution across his insider trading record.
