GRBK Green Brick Partners, Inc. Insider Trading

GRBK President/COO Dolson sold 35,000 shares for $2,366,600 over 2 days; retains 258,605 shares post-transaction

Jed Dolson, President and COO of Green Brick Partners, executed 2 separate sales totaling 35,000 shares for $2,366,600 on 2025-08-12 and 2025-08-13 at blended average price $67.62, reducing his holdings by -11.9% to 258,605 shares. The transactions occurred near the stock's recent strength—the company trades at current price $70.34 with 30-day change of +10.3% and 90-day change of +11.6%—yet below its 52-week high of $83.77. Fundamentally, Green Brick delivered robust results with revenue of $549,147,000, net income of $81,948,000, annual revenue growth of +18.1%, and a low P/E of 8.76, suggesting the business is performing well. Notably, Dolson's prior 2 sales at GRBK (December 2023) did not exhibit well-timed execution: the 90d returns were +3.5% and +9.7%, meaning the stock rose after those sales, and neither of the 2 prior same-ticker sells were well-timed at the 90-day mark. This filing presents a material reduction in insider position during a period of stock strength and favorable fundamentals, warranting review of transaction context and intent.

Director Einhorn executes offsetting sale/purchase of 1,017,163 shares at $69.16; ends with 8.64M shares as stock trades near 52-week lows.

Director David Einhorn executed 2 separate sales totaling 1,017,163 shares for $70,346,993.08 paired with 1 purchase of 1,017,163 shares for $70,346,993.08—a monetarily neutral transaction at identical pricing ($69.16 per share). The timing coincides with significant price weakness: GRBK is down 17.1% from its 52-week high and down 17.1% over the past 30 days, though the stock remains above its 52-week low of $44.70. Einhorn's prior sales at this ticker (5 instances dating back to 2023) have consistently been followed by stock appreciation, with 30-day and 90-day returns ranging from +12.4% to +34.8%—none were well-timed at the 90-day mark. His post-transaction holding of 8.64M shares represents a stable long-term position despite the offsetting trades, suggesting the transaction may reflect technical or tax-related restructuring rather than a directional conviction change. The fundamental backdrop shows a low P/E of 8.81 against $523.7M quarterly revenue and $89.1M net income.

CEO James R. Brickman sells 14,100 shares of GRBK for $1,088,904.12 at blended average $77.23/share

CEO James R. Brickman executed 2 separate sales totaling 14,100 shares for $1,088,904.12 on August 23, 2024, reducing his holdings from 1.61M to 1.60M shares (a -0.9% net decrease). The sale occurred when the stock was trading near its 52-week high ($79.25 current price is -0.6% from the $79.76 peak), after a strong 90-day rally of +44.8%. Given the company's strong fundamentals (P/E of 10.57, $105.4M net income on $560.6M quarterly revenue), the transaction represents a modest portfolio adjustment rather than a wholesale exit; the CEO retains substantial ownership at 1.60M shares post-sale. The timing of the sale near the stock's peak, combined with the 30-day and 90-day momentum context, provides the data point but no FLAG restricts interpretation of trade timing.

CFO Richard Arthur Costello sold 15,000 GRBK shares at $72.75; reduces holdings 28.8% to 37.1K shares

Richard Arthur Costello, Chief Financial Officer of Green Brick Partners, sold 15,000 shares at $72.75, reducing his holdings by 28.8% to 37,116 shares post-transaction. The $1.1M sale occurred near the 52-week high of $74.81 (-2.5%), and the company maintains strong fundamentals with net income of $105.4M on revenue of $560.6M and a P/E of 9.72. Notably, Costello's prior sale at GRBK on 2024-05-06 generated a 90-day return of +26.5%, meaning the stock rose substantially after that sale—a poorly-timed outcome relative to the insider's interest in exiting. This current sale's timing proximity to the 52-week high warrants investor attention to whether management sentiment has shifted regarding near-term valuation or capital allocation priorities.

Director Einhorn sells 1,000,000 shares (1.00M) at $57.80 for $57,802,500.00 in 2 separate transactions

Director David Einhorn divested 1,000,000 shares in two separate sales on 2024-07-11, reducing his holdings by -43.4% from 2,302,690 to 1,302,690 shares. The 1.00M share sale at $57.80 occurred at a price 12.4% below the current $66.02, indicating the stock has appreciated since the transaction. His prior four sales at GRBK showed mixed timing outcomes: 3 of 4 achieved positive 90-day returns (ranging +9.0% to +31.0%), while only the 2023-09-06 sale showed a negative 90-day return (-10.9%), meaning his same-ticker sell timing has been consistently poor by the measure of capturing downside (0 of 4 well-timed). The substantial magnitude—disposing of 43.4% of holdings in a single filing day—alongside the recent strong price momentum (+15.5% in 30 days, +23.9% in 90 days) and a reasonable valuation (P/E 9.77) suggests this represents a significant portfolio action rather than a routine rebalance.
