Paul McAndrew, the CEO of Mueller Water Products, sold 40,000 shares of $MWA on August 10, 2026, for $1,055,572, a transaction that reduced his holdings by roughly 48 percent. The open-market sale was disclosed in a Form 4 filing submitted to the SEC the same day. After the sale, McAndrew retained 42,556 shares.
The shares were sold at an average price of $26.39. Mueller Water Products, a machinery sector firm with a market capitalization near $4.2 billion, makes equipment for water transmission, distribution, and measurement. Its stock had traded between $24.60 and $27.09 over the six weeks before the transaction. McAndrew's sale is his only Form 4 filing in the database, so no personal trading history on $MWA is available for additional context.
The transaction adds to a series of insider sales at $MWA across 2025 and 2026. On May 28, 2026, Chief Technology Officer Marietta Edmunds Zakas sold 54,254 shares in an open-market trade totaling $1,370,586. Vice President Todd P. Helms executed two open-market sales in early 2026: 10,720 shares on February 19 for $318,548, and an equal block of 10,720 shares on March 17 for $295,952. In December 2025, Helms sold 8,015 and 7,079 shares on a single day, generating roughly $371,616. Steven S. Heinrichs, classified as an "Other" insider, completed multiple sales in late 2025, including two on December 9 that together totaled 33,522 shares for roughly $814,105. Director Thomas J. Hansen sold 24,005 shares in August 2025 for $627,719, and Director Jeffery S. Sharritts sold 7,700 shares that same month for $198,822.
Insider buying has been less frequent but did occur. Director Gregg C. Sengstack purchased 25,000 shares on February 25, 2026, for $739,415 at $29.58 per share. Director Brian C. Healy made a series of smaller open-market purchases: 1,125 shares in January 2026, 1,166 in May, and 1,183 in July, each valued between approximately $27,000 and $30,000. Healy also bought shares in October 2025 and July 2025 at similar sizes.
In Congress, Representative Michael T. McCaul, a Texas Republican, disclosed three purchases of $MWA stock during 2026. The STOCK Act filings showed transactions on February 3, May 18, and May 29, each at a midpoint estimate of $15,001. The May purchases fell during the same period when several insider sales and director purchases were occurring. Congressional financial disclosures use broad dollar ranges, so the stated values are midpoint approximations derived from those ranges.
