[144] Waystar Holding Corp. SEC Filing

Rhea-AI Filing Summary

Waystar Holding Corp. – Form 144 filing (07/21/2025)

An affiliate insider (Craig Bridge) intends to sell up to 85,000 common shares of Waystar Holding Corp. through Morgan Stanley Smith Barney. The planned sale represents roughly 0.05 % of the 173.0 million shares outstanding and has an estimated aggregate market value of $3.12 million based on recent prices. The shares derive from options exercised on 07/19/2024 and will be sold on or after 07/21/2025, potentially under a Rule 10b5-1 trading plan.

The filing also discloses prior 10b5-1 sales by the same insider: 15,946 shares sold on 06/11/2025 generating $649,178 in gross proceeds. No adverse information is asserted by the filer, and the transaction appears routine for liquidity diversification.

Insights

Equity Research Analyst

TL;DR: Small insider sale (~0.05 %)—low impact.

The proposed 85 k-share sale is immaterial relative to Waystar’s float and follows typical post-exercise monetisation. Together with June’s 15.9 k shares, total YTD disposals by Craig Bridge remain well below levels that might signal negative sentiment or impair liquidity. Absence of adverse disclosures or unusual timing suggests routine diversification. Impact on price or fundamentals is negligible.

Corporate Governance Specialist

TL;DR: Routine Form 144; governance risk minimal.

The notice meets Rule 144 requirements: shares held >6 months since option exercise, broker identified, and 10b5-1 plan referenced. Volume limits (1 % of outstanding shares or weekly trading volume) are comfortably met. No red flags regarding undisclosed information. From a governance standpoint, the filing is compliant and non-problematic.
