Director Heidi Miller purchases 7,200 shares of WAY at $26.25; stock now $26.58, down 39.2% from 52-week high

Director Heidi Miller initiated a position in Waystar with a purchase of 7,200 shares at $26.25 on March 2, 2026, establishing her first holding in the company. The purchase occurs as the stock trades 39.2% below its 52-week high of $43.69 and has declined 24.5% over the past 90 days, creating a backdrop of significant downward price momentum. Miller's cross-ticker track record shows 2 prior open-market sales with a 0.00% well-timed rate, indicating her historical sells did not precede gains—though this cross-ticker pattern provides limited predictive value for timing at Waystar specifically. Waystar's fundamentals remain intact with revenue of $268.7M, net income of $30.6M, annual revenue growth of 16.5%, and a P/E of 21.10, suggesting operational stability despite the recent stock decline.

Significance 6/10

Director Heidi Miller sells 30,000 FI shares for $6,033,842.62, reducing holdings by 47.4% to 33.2K shares

Director Heidi Miller executed 2 separate sales on 2024-10-30, selling 30,000 shares at a blended average price of $201.13 for total proceeds of $6,033,842.62. This represents a substantial reduction in her position—she held 63,235 shares pre-transaction and retained 33,235 shares post-transaction, a net reduction of 47.4%. The sales occurred near the 52-week high of $203.29, with the stock currently trading at $197.90 (-2.6% from that peak). Against the broader backdrop of the company's strong recent performance (90-day stock gain of 24.5%, annual revenue growth of 7.6%, and market cap of $112.6B), this large directional sell by a board member is a significant data point for investors to monitor, particularly given the magnitude of the position reduction.
