SAINT FREDERICK G.

COSTAR President buys 20,000 shares at $45.33; stock down -51.7% from 52-week high. Cluster buy by 2 other insiders in past 14 days.

Frederick G. Saint, President of Marketplaces at CoStar, purchased 20,000 shares at $45.33 on 2026-03-02, increasing his holdings by 7.7% to 279.9K shares. The purchase occurred as the stock trades 51.7% below its 52-week high of $96.83 and has declined 23.9% in the past 30 days and 32.2% over 90 days. Saint's cross-ticker track record shows 3 prior sells with a 66.67% well-timed rate at the 90-day mark, though his two most recent same-ticker sales at CSGP (Aug-28 and Jul-28, 2025) were both well-timed against declines. The buy is part of a broader cluster pattern, with 2 other insiders purchasing within the past 14 days, suggesting coordinated confidence at depressed valuations. However, CoStar's fundamentals present complexity: the company reported net income of $-30.9M in the latest quarter despite 18.7% annual revenue growth, and trades at an extreme P/E of 2339.00, reflecting market skepticism about near-term profitability even as top-line growth accelerates.

CSGP President Frederick G. Saint sold 25,000 shares at $90.33 on 2025-08-28; stock now at $88.12 (-9.0% from 52-week high).

Frederick G. Saint, President of Marketplaces at CoStar Group, sold 25,000 shares for $2,258,250.00, reducing his holdings from 318,103 shares to 293,103 shares. The sale occurred at $90.33, and the stock has since declined to $88.12 (a -6.8% move over 30 days). Saint's cross-ticker track record shows 2 prior sells with an average 30-day return of +0.6%, while his same-ticker history at CSGP includes a prior sell on 2025-07-28 that experienced a -4.0% 30-day return. The company shows strong annual revenue growth of +11.4% to $781,300,000.00, but a notably elevated P/E of 352.48 and minimal profitability ($6,200,000.00 net income) warrant attention to valuation dynamics relative to the price action and insider liquidation pattern.

President of Marketplaces Frederick G. Saint sold 25,000 shares (25.0K) of CSGP at $93.23 for $2,330,750.00

Frederick G. Saint, President of Marketplaces, sold 25,000 shares at $93.23, reducing his holdings by 7.3% to 319,539 shares post-transaction. The sale occurred while CSGP stock has appreciated 18.4% over the past 30 days and 28.9% over the past 90 days, trading near its 52-week high of $95.59. Across his cross-ticker track record, Saint has executed 1 prior sell with an average 30-day return of +5.3%, and at CSGP specifically, a prior sale on 2025-06-11 also showed a +5.3% 30-day outcome. The company reports a highly elevated P/E of 382.36 against recent revenue of $781,300,000.00 and net income of $6,200,000.00, indicating significant valuation compression despite 11.4% annual revenue growth. This transaction represents a routine partial reduction in a substantial long position during a period of significant stock appreciation.

CoStar President Frederick Saint sells 25,000 shares at $81.10; holds 344,539 shares post-sale as stock trades near 52-week high

Frederick G. Saint, President of Marketplaces at CoStar Group, sold 25,000 shares (344.5K shares remaining post-transaction) at $81.10 on 2025-06-11, representing a $2.0M transaction. The sale occurred while the stock trades at $82.37, near its 52-week high of $83.22, and follows strong short-term momentum with a 30-day gain of +9.6%. However, context is limited: the company is trading at an elevated P/E of 294.18 despite recent net losses of $-14.8M, and without disclosure of whether this sale was scheduled under a 10b5-1 plan, its timing relative to Saint's historical trading patterns, or any material non-public information, the transaction does not signal a clear strategic change. Saint retains substantial holdings (344.5K shares), suggesting ongoing stakes in the company.
