Director Brian C. Healy buys 1,183 MWA shares at $25.33 under pre-arranged 10b5-1 plan; stock down 17.9% in 90 days

Brian C. Healy purchased 1,183 shares of Mueller Water Products at $25.33 on 2026-07-07 under a 10b5-1 trading plan adopted on 2026-02-11, meaning this purchase was scheduled rather than a discretionary decision. The stock has declined 17.9% over the past 90 days and trades 20.2% below its 52-week high of $31.00, currently at $24.75. Healy's prior open-market purchases across all tickers show an 87.50% win rate with 90-day average returns of +6.6%, but his same-ticker history at MWA is mixed: three prior buys produced positive 90-day returns (+14.4%, +4.9%, +4.9%) while two generated negative results (-6.8%, -8.6%). The company reports trailing-quarter revenue of $384,400,000.00, net income of $59,100,000.00, and annual growth of +8.8%, with a P/E of 18.61. Because this transaction was pre-arranged and not discretionary, it carries limited signal about current conviction; investors should note the recent price weakness and mixed track record at this specific ticker.

Director Gregg C. Sengstack buys 25,000 shares of Mueller Water Products (MWA) at $29.58; first buy in insider history.

Gregg C. Sengstack, a director, made his first open-market purchase on 2026-02-25, acquiring 25,000 shares at $29.58 for a total value of $739,415.00. This is a notable shift in behavior: across his cross-ticker transaction history, he has completed 1 prior buy (with an average 90-day return of 14.7%) but has executed 13 prior sells. The purchase occurs after recent positive price momentum, with MWA trading at $30.12 today, just 0.1% below its 52-week high of $30.15, and showing a 24.3% gain over 90 days. The stock's trading at a 23.53 P/E against fundamentals including $318.2M in latest quarterly revenue, $43.2M net income, and 8.8% year-over-year revenue growth. While the timing—purchasing near a 52-week peak after significant recent appreciation—differs from the well-timed sell patterns evident in his prior transactions (77.78% of his 13 prior sells were followed by stock declines), this purchase represents a material commitment to the company at current levels.

Steven S Heinrichs executed 10 separate sales on 2025-03-05 totaling 195,433 shares for $4,864,587.82, reducing his Mueller Water Products holdings by 94.5% from 206,831 to 11,398 shares.
