Howley W Nicholas has filed 234 Form 4 transactions across two companies, with a clear and sustained selling bias. The total value of open-market sales is $132.8 million, while open-market purchases total zero. The only other acquisition activity is $137,256.58 in grants or awards, which are compensation events rather than discretionary buys. The recent pattern is concentrated entirely in TDG, the ticker for TransDigm Group. On August 18, 2026, Nicholas filed 14 open-market sales on TDG, ranging from $85,933.55 to $4,931,914.91. The combined value of those August sales is roughly $12.4 million. That same day, he also exercised options worth $673,474.04, a mechanical transaction that typically precedes or accompanies share sales. On July 20, 2026, he filed 10 open-market sales on TDG, with individual values from $158,673.61 to $2,085,897.66, totaling about $11.4 million. Across the 24 most recent trades, all are sales except for the single option exercise. The selling is consistent in timing, with trades clustered on the 20th and 18th of consecutive months, and the dollar amounts are substantial. The absence of any open-market purchases in the entire filing history, combined with the steady monthly sales in TDG, shows a one-directional pattern: Nicholas is a net seller, and the recent activity does not deviate from that trend.
