Don Sullivan, a vice president at $CSW Industrials, Inc., sold $1,555,812.50 worth of stock on August 5, 2026, disposing of 4,526 shares at $343.75 each. The open-market transaction was reported via Form 4 the same day. Sullivan held 17,041 shares directly afterward.
The sale continued a pattern of regular dispositions by Sullivan. He sold 4,136 shares at $301.41 in December 2025, netting approximately $1.25 million, and followed with a 166-share sale at $300.26 in April 2026. Earlier, he made a series of sales in June, July, and August 2025 at prices ranging from about $283 to $305. The August 5 price of $343.75 was the highest among his disclosed open-market sales in that period.
Other insiders were selling, too. CEO Joseph B. Armes sold roughly 1,000 shares a month through much of 2025 and into early 2026, including 1,500 shares each in February, March, and April 2026. VP Luke Alverson sold in April and May 2026, while CFO James E. Perry and CTO Jeff Underwood each made sales in late 2025. The only open-market purchase by a $CSW insider over the past year was by Director Darron K. Ash, who bought 300 shares at $256.62 on March 13, 2026, for $76,986.
On the congressional front, Representative Gilbert Cisneros (D-Calif.) disclosed five purchases of $CSW shares between November 2025 and May 2026. Each fell in the $1,001–$1,001 range, with a $1,001 midpoint estimate. The trades occurred on November 6, 2025; November 18, 2025; January 15, 2026; March 3, 2026; and May 18, 2026. Disclosure delays on those filings ranged from 21 to 39 days. Representative Josh Gottheimer (D-N.J.) also reported a $CSW purchase on November 17, 2025, within the same range.
$CSW shares closed at $349.31 on August 4, the day before Sullivan’s sale. The stock had risen from a $260.20 close on May 18, 2026, when Cisneros made his most recent purchase, and from $256.62 where Director Ash bought in March. Sullivan retained 17,041 shares after the transaction.
