Charles Dirkson R

Loar exec Dirkson bought 44,000 shares ($3.0M) across 3 days at $67.41–$67.49; stock now $63.03 (-36.6% from 52-week high). Cluster buy pattern.

Charles Dirkson R executed 3 separate purchases totaling 44,000 shares (44.0K shares) for $2,967,830.64 ($3.0M) over March 10–12, with a blended average price of $67.45. This addition represents a +1.1% increase in his holdings (now 4,087,005 shares post-transaction). The buys occur during a period of stock weakness: the current price of $63.03 sits -36.6% from the 52-week high and -3.6% over 30 days. At LOAR specifically, Dirkson's prior 3 trades were all sells (conducted May 2025 and December 2024), each well-timed at the 90-day mark with subsequent declines ranging from -13.4% to -21.6%. His cross-ticker buy track record shows 1 prior open-market buy with a +29.4% average 90-day return (100% win rate on buys). A cluster pattern is present: 2 other insiders also bought within the past 14 days alongside this filing. The company's fundamentals remain solid (revenue $126.8M latest quarter, annual growth +23.2%), though the elevated P/E of 52.09 and significant recent drawdown from recent highs provide the context for this discretionary purchase.

Director Charles Dirkson bought 5,000 BLDR shares at $109.67 on 2025-05-27, doubling holdings to 10,237 shares amid -46.0% decline from 52-week high.

Charles Dirkson, a director of Builders FirstSource, acquired 5,000 shares for $548,350.00, increasing his holdings by 95.5% from 5,237 to 10,237 shares in a single open-market transaction. The purchase occurred at $109.67 per share, above the current price of $108.93 but well below the 52-week high of $201.83—a 46.0% decline from peak. His cross-ticker track record shows 3 prior sells with a 100.00% well-timed rate, meaning those sales preceded downward moves; however, this buy activity does not map against his historical pattern. BLDR's fundamentals show annual revenue contraction of -4.1% against a market cap of $12.0B and P/E of 13.16, providing context for the valuation at which the director is adding exposure.

Charles Dirkson R sold 678,372 shares for $54,885,518.27 in two transactions at LOAR on 2025-05-16 and 2025-05-19

Charles Dirkson R executed two separate sales totaling 678,372 shares (14.4% of pre-transaction holdings) at a blended average price of $80.91 on 2025-05-16 and 2025-05-19. His cross-ticker track record shows 1 prior sell with a 90-day well-timed rate of 100.00%, and at LOAR specifically, his 2024-12-12 sale exhibited a 90d return of -21.6%, indicating a pattern of selling ahead of price declines. The current price of $84.94 is now above his transaction prices, but this filing merits attention given the insider's demonstrated track record of well-timed exit decisions and the substantial dollar volume of the disposition ($54.9M). Post-transaction holdings of 4.04M shares remain substantial, though the -14.4% reduction signals a meaningful shift in position sizing.

Charles Dirkson sold 126,960 shares of LOAR at $81.18 on 2024-12-12; retains 4,721,377 post-sale.

Charles Dirkson sold 126,960 shares at $81.18 for $10,305,978.00 on 2024-12-12, reducing his holdings by 2.6% to 4,721,377 shares. The sale occurred at a price $1.31 above the current price of $79.87, placing the transaction near the upper portion of the recent 30-day and 90-day price range. At $7.2B market cap with latest quarterly revenue of $103,519,000.00 and net income of $8.656,000.00, Dirkson remains a substantial shareholder with over 4.7M shares outstanding post-transaction, indicating continued material investment in the company. The moderate reduction in holding size, absence of additional context flags, and Dirkson's continued significant stake suggest routine portfolio activity rather than a signal of fundamental concern about the business.
