Significance 4/10

GRNT CEO Brandenberg buys 6,100 shares at $5.80; second buy in 3 weeks amid rally, but P/E of 63.89 marks premium valuation.

Brandenberg Luke C, President and CEO, purchased 6,100 shares at $5.80, increasing his holdings by 4.0% to 157,267 shares. This is his second open-market buy at GRNT in three weeks (prior purchase on 2025-05-15), occurring as the stock has rallied +17.1% over the past 30 days. However, his prior four measurable trades at GRNT show a 0% win rate at the 90-day horizon, with outcomes of +13.5%, +13.0%, +7.4%, and -9.3% at 30 days but -8.7%, -10.0%, -9.7%, and -6.7% at 90 days, indicating that initial gains have consistently reversed. The company carries a notably elevated P/E ratio of 63.89, and annual revenue contracted 3.6% year-over-year, which limits conviction signals from fundamentals alone. Investors should note the repetition of the pattern: near-term price appreciation followed by longer-term erosion.

Significance 6/10

GRNT CEO Brandenberg purchased 18,252 shares at $5.55 (2025-05-15); post-trade holdings 151,167 shares; concurrent cluster buy pattern

CEO Luke C Brandenberg purchased 18,252 shares of GRNT at $5.55 on 2025-05-15, increasing his holdings by 13.7% to 151,167 shares, a material accumulation by the chief executive. The stock trades at $5.65 currently (above the transaction price) but remains 19.9% below its 52-week high, though up 15.1% over 30 days. At the same-ticker level, Brandenberg's prior 5 purchases at GRNT showed a 0 of 5 well-timed record at the 90-day mark (none resulted in 90-day gains), with 90-day returns averaging -8.1% across those trades. The company carries a high P/E of 62.78 against $9.8M net income on $122.9M quarterly revenue, with annual revenue declining 3.6% year-over-year. The transaction occurred within a cluster pattern—2 other insiders also bought within the past 14 days—which adds incremental signal strength despite the insider's mixed timing history at this particular ticker.

Significance 6/10

CEO Brandenberg buys 10,000 GRNT shares across 2 transactions totaling $60,954.85; 3 other insiders bought within 14 days

Luke C. Brandenberg, President and CEO, completed two separate purchases totaling 10,000 shares (10.0K shares) for $60,954.85 on 2024-12-11 and 2024-12-12, at a blended average price of $6.10, increasing his holdings from 100.6K shares to 110.6K shares (+9.9%). The stock currently trades at $6.14, down 12.9% from its 52-week high of $7.05 and down 6.8% over the past 30 days, near the lower end of its $5.29–$7.05 range. Significantly, three other insiders have also purchased shares within the past 14 days, forming a cluster buy pattern. Brandenberg's prior purchases at GRNT show 2 of 2 measurable outcomes with positive 90-day returns (+7.1% and +3.4%), and his broader cross-ticker track record spans 10 prior buys with a 71.43% 90-day win rate and average 90-day return of +9.7%. Fundamentals show the company generated $94.1M in quarterly revenue with $9.1M net income, though facing a -20.8% annual revenue decline, at a P/E of 16.59. The convergence of CEO purchasing, peer insider buying, and historical timing acumen at this ticker warrants investor attention, though near-term headwinds (revenue contraction and recent price weakness) create a mixed backdrop.

Significance 7/10

GRNT CEO Brandenberg buys 1,500 shares at $6.21; 3rd buy in 14 days amid cluster pattern, 90d track record 71.43% win rate

Brandenberg Luke C, as President and CEO, purchased 1,500 shares of Granite Ridge Resources at $6.21 on 2024-12-05, raising his holdings from 99,133 to 100,633 shares (+1.5%). This transaction is part of a larger buying cluster: 2 other insiders purchased shares within the same 14-day window, suggesting coordinated confidence at current valuations. His same-ticker history shows 5 prior purchases at GRNT over the past seven months, with 3 of 3 measurable outcomes showing positive 90-day returns, including a +7.1% 90-day gain on the 2024-08-13 buy. His cross-ticker track record spans 9 prior open-market buys with a 71.43% 90-day win rate and +9.7% average 90-day return. The stock trades at $6.24 currently, down 11.5% from its 52-week high of $7.05 but up 4.7% over 90 days. Against this context, the CEO's repeated accumulation at modest valuations (current P/E 16.86, market cap $815.8M, latest quarterly net income $9.1M) alongside peer purchases suggests conviction at these price levels, though the company's annual revenue has contracted 20.8% year-over-year, warranting closer inspection of operational trends.

Significance 6/10

GRNT CEO Brandenberg bought 2,500 shares at $6.57 on 2024-11-26; 4 other insiders also purchased within 14 days.

Brandenberg Luke C, President and CEO of Granite Ridge Resources, purchased 2,500 shares at $6.57 on 2024-11-26, expanding his holdings to 99,133 shares. This buy occurs within a cluster pattern—4 other insiders also acquired shares within the past 14 days—which may reflect coordinated confidence or alignment around current valuation. Notably, Brandenberg's prior trades at GRNT show 3 of 4 measurable outcomes were well-timed at the 90-day mark, suggesting his buying pattern has historically preceded price appreciation at this ticker. However, the company faces headwinds: annual revenue declined -20.8% year-over-year, and the stock trades at a P/E of 17.70 against a market cap of $856,372,885.60, with current price $6.55 sitting -7.1% below its 52-week high. The cluster buy may warrant attention to whether management perceives near-term value inflection despite recent revenue contraction.

Significance 7/10

President/CEO Brandenberg bought 5,000 shares at $6.50; cluster pattern: 3 other insiders also bought within 14 days

Luke C Brandenberg, President and CEO of Granite Ridge Resources, purchased 5,000 shares at $6.50 on 2024-11-15, increasing his holdings to 96,633 shares. The transaction coincides with a cluster pattern: 3 other insiders also bought within the past 14 days, suggesting coordinated conviction across the executive team. His same-ticker history at GRNT shows mixed timing outcomes (3 of 5 prior buys delivered positive 90-day returns), and the current price of $6.61 sits 6.2% below the 52-week high. The underlying business shows challenges: annual revenue declined -20.8% year-over-year despite current-quarter revenue of $94,100,000.00 and net income of $9,054,000.00. The cluster buy pattern and CEO-level participation merit attention, particularly given near-term price momentum (+8.5% over 30 days) and the question of whether this reflects confidence in turnaround prospects or stabilization.

At the company level, fundamentals show mixed signals: revenue of $90.7M with positive net income of $5.1M, but annual revenue declined -20.8% year-over-year. His prior purchases at GRNT show variable outcomes: 2 of 4 measurable 90-day outcomes were well-timed (the 2023-09-15 buy returned +23.4% in 90 days), but two resulted in negative returns. This transaction occurs while the stock remains -4.6% down over the past 30 days, and represents a modest position increase of 5.8% relative to his pre-transaction holdings.

Significance 6/10

CEO Luke C Brandenberg buys 5,000 GRNT shares at $5.93; stock -26.2% from 52-week high amid 2 concurrent insider buys

Luke C Brandenberg, President and CEO of Granite Ridge Resources, purchased 5,000 shares at $5.93, raising his holdings to 86,633 shares (+6.1% net change). The stock currently trades at $5.91, -26.2% from its 52-week high of $8.01, and has declined 8.5% over the past 30 days. This purchase occurs within a cluster pattern: 2 other insiders also bought within the past 14 days, suggesting aligned conviction among leadership despite recent weakness. Notably, Brandenberg's prior trades at GRNT show mixed timing results—his May 2024 buy declined 2.1% within 30 days, though earlier 2023 purchases at this ticker delivered positive 90-day returns of +23.4% and +37.6%. The company's fundamentals show revenue of $89.0M and net income of $16.2M in the latest quarter, but annual revenue contracted -20.8% year-over-year, and the valuation (P/E: 12.85) remains compressed. The convergence of insider accumulation despite macroeconomic headwinds and depressed price levels warrants monitoring of execution outcomes.
